Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to at least one hardening compaction roller which can be swiveled around an axis parallel to a rotational drive axis of a device for rotationally driving a main shaft of a crankshaft. A compaction device having a head support lever and at least one further compaction device;
The present invention relates to a device for rolling or smoothing compaction of a crankshaft, wherein the rolling device is supported by a stand arranged on a slider.

2. Description of the Related Art Known devices of this type are configured to be mounted on the carriage of a lathe or a machine similar to a lathe. The lathe receives the workpiece to be compacted, in particular the crankshaft to be compacted, on the one hand on the chuck and, on the other hand, on the center of the spindle for rotational driving. Each time the required rolling device is moved with the tool to the shaft location to be rolled, the required rolling force is applied and the crankshaft is driven by the lathe. The rolling device for the connecting rod shaft to be rolled is entrained by the connecting rod shaft for its oscillating suspension. In the rest position, the device is balanced through the elastic member. However, there is a drawback in that the main shaft of the crank shaft of various crank arm lengths and the shaft for the connecting rod cannot be simultaneously and continuously machined by the known apparatus.

(Problem of the invention) An object of the present invention is to apply a compaction device of the type described at the beginning to a compaction device having compacting tools, which can be applied to crankshafts of various sizes, and a main shaft of the crankshaft and a shaft for connecting rod. Is to be configured so that and can be processed simultaneously and continuously.

(Means for Solving the Problem) The problem to be solved by the present invention is solved by the configurations described in claims 1 and 17. As a result, the rotation of the main shaft of the lathe causes the main shaft of the crank shaft to rotate, and the main shaft is compressed by the hardening compaction device, and at the same time, the shaft for the connecting rod moves on a circular orbit around the axis of the main shaft of the crank shaft. As a result, it is possible to roll the connecting rod shaft while moving following the movement of the connecting rod shaft.

(Embodiment) Two rolling devices are variable in relative position, one rolling device is fixed in its position, and the other rolling device is pivotally supported at one end thereof on a slider so as to be rotatable around an axis and the other. First by being pivotally supported by the pivot at the end
FIGS. 3 to 3 show the constitution of a hardening compaction device 1 or 1'for machining the main shaft 3 of the crankshaft 5, and FIGS.
The apparatus shown in FIG. 6 uses a hardening rolling device 1 or 1'according to FIGS. 1 to 3 and combines it with a movable hardening rolling or smooth rolling device 50 to form a main shaft 3 of a crankshaft. 1 shows a device for hardening rolling or smooth rolling and the similar rolling of the connecting rod shaft 4. The hardening rolling device 1 or 1 ′ and the movable hardening rolling or smoothing rolling device 50 have the same basic structure. In the embodiment, one is arranged invariably and the other is arranged variably. The functionality of these devices is similar except that they are present.

According to FIGS. 4 to 6, the movable compaction device 50 is pivotally mounted on the slider 47 at one end thereof via a shaft 40 parallel to the rotary drive axis 46 of the device for rotationally driving the main shaft of the crankshaft. The other end of the pivoting arm 51 pivotally supported is pivotally supported by a pivot 60 parallel to the axis 46 so as to be swingable around the pivot 60. As a result, when the crankshaft 5 is rotationally driven around the axis of the main shaft 3, the rotation of the connecting rod shaft 4 on the circular orbit causes the swiveling arm 51 to swivel with respect to the slider 47 and the other pivotal shaft 60 with respect to the swiveling arm 51. The swing of the compaction device 50 expands or contracts the distance from the shaft 40 to the hardening compaction roller head of the other compaction device 50. The two parallel swivel arms 51 also have one angle lever for swiveling in the same plane.
It is equipped with 56 pivotally, and this angle lever 56 is a swing arm 51.
Is operatively connected to a hydraulic cylinder 57 fixed to. The free end 58 of the angle lever 56 is moved by the retractable piston rod of the hydraulic cylinder 57, as shown in FIG.
It can be pressed against 50, thereby serving to adjust its reference position when swinging the movable compaction device 50 around the pivot 60 in the plane of the drawing with respect to the swivel arm 51 before the start of processing. . This oscillating movement positions the movable compaction device 50 at the predetermined machining start position shown in FIG. 4, which is to be newly aligned with respect to the crankshaft of other dimensions and to be compacted. Necessary for positioning at the shaft location. However, since the center of gravity S of the movable compaction device 50 is located in front of the pivot 60 as shown in FIG. 4, the movable compaction device 50 is movable by the moment around the pivot due to its own weight. The pressure device 50 is an angle lever 56
The free end 58 of the.

The swivel arm 51 is pivotally supported by a slider 47 so as to be swivelable around a shaft 40 arranged in parallel with a pivot 60. The slider 47 is slidably guided by a slider support 48 having a slider guide 49 which is movable laterally with respect to the axis 46 of the crankshaft 5 (FIG. 5). Slider support 48
Is supported by a support column 41 formed as a circular guide, which support column 41 adjusts the heightwise position of both rolling devices 1 or 1'and 50 to match the dimensions of the crankshaft 5 to be machined. For this purpose, it is arranged vertically adjustable on the stand 42. This adjustment direction is indicated by arrow 66 (Fig. 5). For this purpose, the support column 41 is provided on its inner lower side with an internal thread which cooperates with a screw spindle 67. This screw spindle
67 has a bevel gear 68 rotatably and axially slidably supported inside the stand 42. The bevel gear 68 is an adjusting device.
It meshes with the bevel gear 69 of 70. The adjusting device 70 is formed in this embodiment as a square shaft, which can be rotated via a key or a handle. Of course, it is also possible to provide a motor that is controlled so that automatic adjustment can be performed.

In order to adjust the position of the movable compaction device 50 so as to suit the machining of the crankshaft 5 of various sizes, the slider guide 49 of the slider support 48 before the machining of the crankshaft 5,
The slider 47 can be adjusted perpendicularly to the axis 46 of the crankshaft 5 (in the direction of arrow 59) (FIG. 4). Slider support 48
The bracket 62 is provided on the bracket 62.
A handle 45 of the adjusting drive is rotatably mounted on the. This handle 45 engages a suitable screw 71 on the slider 47, so that when the handle 45 is turned, the slider 47 will correspondingly move in the radial direction (direction of the arrow 59) and thus the crankshaft 5.
Is slid in the tangential direction of the cross-section circle of the connecting rod shaft 4. Of course, instead of the handle 45, it is also possible to provide a suitably controlled motor for automatic adjustment.

As can be seen from FIG. 4, a hardening rod device 1 or 1 ′ for hardening and rolling the main shaft 3 and the connecting rod shaft 4 of the crankshaft 5
A movable compaction device 50 for curing compaction and rolling is supported by the slider support 48 and the slider 47, respectively. The hardening roller 1 or 1'is slightly flexibly fixed directly to the slider support 48, as can be seen in FIG. As already mentioned, a slider 47, which is formed as a circular guide for supporting the slider 43, is guided by a slider support 48, on which an extended shaft 40 of the slider 43 pivots outwardly as already mentioned. Arm 51 is provided (fourth
Figure). Since this slider 43 carries out hardening rolling over the entire length of the connecting rod shaft 4 of the crankshaft 5, the machining is interrupted before or during the machining of the crankshaft 5, and the machining is interrupted in the slider 47 by the arrow 72. It is arranged so that it can slide in any direction (Fig. 5). Sliding in the direction of the arrow 72 is realized via an adjusting drive, which in this embodiment is the handle 44, and a screw spindle 61 connected to the handle, which screw spindle 61 engages with a corresponding internal thread of the slider 43. I am fit. A handle 44 with a threaded spindle 61 is rotatably but immovably supported in a slider 47 so that a proper rotation of the handle 44 causes the slider 43 to move axially (arrow 72 direction). As a result, the lateral distance between the movable compacting device 50 and the hardening compacting device 1 or 1'is changed, so that the relative position of both compacting devices is the relative position of both compacting devices. Can be adapted to various lengths of the crank arm connecting the main shaft 3 with the main shaft 3. Of course, the handle 44 can be replaced by a motor, so that the above adjustments can be made automatically.

In order to move the total rolling device to the working position or to return from the working position to the preparation position, the total rolling device is moved to the axis line 46 of the crankshaft 5.
Is provided on the carriage 73 so as to be slidable in the lateral direction, that is, in the direction of the arrow 59 '. Although not described in detail here, this sliding can take place for example via a hydraulic cylinder or a handle or a screw spindle with a motor. On the one hand the movement of the slider 47 in the direction of the arrow 59 serves for adjustment to the stroke of the crankshaft (length of the crank arm) (Fig. 4) and on the other hand brings the entire device into the working position as already mentioned, or Carriage to separate from the processing position
The entire device is moved on 73 in the direction of arrow 59 '.

According to the present invention, one compacting or smooth compacting device 1 or 1'and a movable compacting device 50 are configured as compact units to compact and compact one main shaft 3 of the crankshaft 5 and one connecting rod shaft 4. In this case, in order to roll the plurality of main shafts 3 and the plurality of connecting rod shafts 4 of one crankshaft 5,
Before the machining of the new main shaft 3 and the connecting rod shaft 4 is started, the entire device is moved along the axis 46 of the crankshaft 5 while maintaining the relative position of the hardening roller 1 or 1'and the movable roller 50. Need to move in the direction. This is accomplished by sliding carriage 73 in the direction of arrow 72 'on the machine bed. For this purpose, the carriage 73 is moved in a known manner on the machine bed via the screw spindle 74 in the direction of the arrow 72 '. The screw spindle 74 can also be manually operated or controlled by a suitably controlled motor to automatically slide in the direction of arrow 72 '.

Below the slider 47, hydraulic cylinders 52 and 53 are provided in front of and behind the revolving arm 51 via support members 76 and 75, and both hydraulic cylinders 52 and 53 act in mutually opposite directions. Before starting the machining, the turning position of the turning arm 51 is set according to the length of the crank arm of the crank shaft 5.
Serve to adjust by piston rods 64 and 65 abutting against. In order to move the swivel arm 51 to the first swivel position 54, one hydraulic cylinder 53 is connected to the other hydraulic cylinder 52.
Driven by a greater force than that, and the piston rod 65 is extended until it hits the stopper, and the swing arm 51 moves to the first position.
Occupy the turning position 54 of. Turn the swivel arm 51 to the first swivel position
The piston rod 64 of the other hydraulic cylinder 52 is moved towards the swivel arm 51 in order to position it at 54 and thus the first
At the turning position 54, the turning arm 51 is positioned by being sandwiched between the piston rods 65 and 64. In this turning position, the movable rolling device 50 can be brought into contact with the shaft portion to be rolled. After the predetermined positioning of the swivel arm 51, during machining of the crankshaft 5, the piston rods 64 and 65 of both hydraulic cylinders 52 and 53 are retracted outside the swivel motion range of the swivel arm 51, and thus to the range where they do not contact the swivel arm 51. To be At this time, similarly, the free end 58 of the angle lever 56 is also flipped high upward from the device so that the movement of the movable compaction device 50 is not hindered by the extension of the piston rod of the hydraulic cylinder 57.

The swivel arm 51 can be located in the second swivel position 55, this operation being performed by the piston rod of one hydraulic cylinder 53.
This is done by fully retracting 65 and unrolling the piston rod 64 of the other hydraulic cylinder 52 until the pivot arm 51 abuts the retracted piston rod 65 for its pivoting motion. At that time, only the movable compaction device 50 is swung from the machining device of the device to the rest position, and all compaction devices including the hardening compaction device 1 or 1 ′ are not pulled back from the machining position. There is no need to change the basic position of the device. When the second turning position 55 is not sufficient, the angle lever 56 is repelled, and the movable compaction device 50 tilts the roller head side downward in the drawing plane due to the position of its center of gravity S. The free end 58 of the lever 56 is flipped up to a position where it no longer abuts the movable compaction device 50, so that only the working spindle 3 can be machined by the hardening compaction device 1 or 1 '. As a result, not only the main shaft 3 of the crankshaft 5 and the connecting rod shaft 4 can be simultaneously machined by the hardening roller 1 or 1 ', but also the correction machining of only the crankshaft 5 can be performed.

Despite the fact that the vertical position of the hardening compaction device 1 or 1'and the movable compaction device 50 is relatively fixed, it should be adjusted to the diameter of the main shaft 3 and / or the connecting rod shaft 4 of the crankshaft 5. The positioning can be easily performed by adjusting the piston-cylinder unit 10 attached to the hardening roller 1 or 1'and the movable roller 50, respectively. FIG. 4 schematically shows a crankshaft 5 having a main shaft 3 and two connecting rod shafts 4 on the left side of the entire apparatus. Both devices are returned to the processing position in the open state, and the main shaft 3 of the crankshaft 5 is
Is in a relative position such that it is hardened by the hardening roller 1 or 1 ', and the connecting rod shaft 4 is hardened by the movable roller 50, and extends parallel to the direction of arrow 59' by a lathe (not shown). The virtual plane 78 is rotated so as to contact both the main shaft 3 and the connecting rod shaft 4. In this position, the entire device consisting of both rolling compactors is simply slid in the direction of arrow 59 and moved to a position that fits the main shaft 3 on the one hand and the connecting rod shaft 4 on the other hand, and the movable compacting device. 50 and the cure compaction device 1 or 1'are closed to provide cure compaction. First, when the diameter of the connecting rod shaft 4 of the crank shaft 5 to be hardened and compressed is changed, the rotational angular position of the crank shaft 5 is only correspondingly changed in the above-mentioned machine (not shown), and The plane 78 again forms a tangent to the main shaft 3 and the connecting rod shaft 4. On the other hand, if the diameter of the main shaft 3 changes, the imaginary plane 78 will be displaced in the vertical direction due to the fixed center of the machine that receives the crankshaft 5, so that a suitable vertical correction will cause the support post 41 to move in the direction of the arrow 66. It is performed by appropriately displacing vertically.

However, when the dimensions of the crankshaft change, at the same time as the change, not only the stroke size of the crankshaft (length of the crank arm) and the rotation angle position, but also the R portion to be compressed,
The diameter of the shaft portion to be rolled and the axial length of the shaft portion to be rolled can be changed at the same time. This requires replacement of the hardening roller compactor head, which in the known art must be done manually. The compaction device according to the invention must eliminate this drawback and should allow automatic adjustment of the entire compaction device before the start of processing in order to adapt it to the various dimensions of the crankshaft. Such curing compaction device 1 or 1 '
The basic structure of the movable compaction device 50 is shown in FIGS. The setting roller 1 comprises two arms 6 and 7. These arms 6 and 7 are connected to each other like scissors via a joint plate 23 and a hinge pin 24 in a known manner. At the rear ends 8 and 9 facing each other, a piston-cylinder unit 10 is likewise arranged in a known manner, which unit moves the arms 6 and 7 in pliers or scissors fashion. The front end 11 of the arms 6 and 7 opposite the rear end 8 and the front end 12 of the arms 6 and 7 opposite the rear end 9 are provided with roller rollers required in the prior art. On the other hand, in the present invention, the hardening compaction device 1 or 1 ′ pivotally supports a fork-shaped lever 19 for supporting the hardening compaction roller and a fork-shaped lever 20 for supporting the supporting roller. Pins 25, 26
Prepared by pivoting each. The levers 19, 20 are thus free to rock around their pivot pins 25 or 26, the rocking directions being indicated by arrows 27 and 26 '.

The piston / cylinder unit 21 is connected to the lever 19 via its piston rod via a pivot pin 28, while the cylinder of the piston / cylinder unit 21 is supported on the arm 6. In the illustrated switching position according to FIG. 1, the lever 19 is in the angular position 15. At the second end of the lever 19, a hardened roller head 13 or 13 ', known per se, is arranged as a double tool in the illustrated embodiment. Lever 19 angular position 15
Now the curing compaction roller head 13 is in the working position.

The support roller head 14 on the lever 20 is also provided facing the curing roller compaction roller head 13 in a manner also known in the art. The angular position 17 of the lever 20 is at the processing position
14 and thus the transition (R) 2 on the main shaft 3 can be compacted. For this purpose, piston cylinder unit
It is necessary for the arms 6 and 7 to be moved via 10 in a manner known per se, so that the setting roller head 13 and the supporting roller head 14 come into contact with the corresponding shaft points of the crankshaft 5. Curing compaction device 1 of FIGS. 1 and 3
Alternatively, a movable compaction device 50 is provided in addition to 1 '(FIG. 4),
The movable rolling device 50 processes the connecting rod shaft 4 of the crank shaft 5, and the hardening rolling device 1 or 1'hardens the main shaft 3 (FIG. 4). The main shaft 3 of the crankshaft 5 is rotated by the rotation of the main shaft of the lathe, whereby the main shaft 3 is compacted by the hardening compaction device 1 or 1 ', and at the same time, the connecting rod shaft 4 revolves around the axis 46 of the main shaft 3. As a result, the movable compaction device 50 also moves together with the connecting rod shaft 4,
At that time, the movable compaction device 50 can perform the compaction compaction of the connecting rod shaft 4 while swinging about the pivot shaft 60 on the swing arm 51 which is swung like a pendulum about the shaft 40 as a fulcrum while being swung. Providing a plurality of compaction devices itself belongs to the known art,
Detailed description is not given here.

In order to cure and roll the main shaft 3 of the crank shaft 5, one end of the crank shaft 5 is received by the center of the lathe and the other end is gripped by the chuck to rotate by the rotation of the main shaft of the lathe as shown in FIG. Driven. At that time, the free end 58 of the angle lever 56 is raised upward from the device so that the movement of the movable compaction device 50 is not hindered by the extension of the piston rod of the hydraulic cylinder 57 during the curing compaction. The crankshaft 5 can be rotated, for example, at 50 to 150 rpm.
Now, when the main shaft 3 of the crankshaft 5 comes as the next workpiece having, for example, the R parts 2 of different sizes, the hardened roller head 13 'is aligned with it. Therefore, in order to roll the R portion 2 of the main shaft 3 of the crankshaft 5 having different dimensions, the piston cylinder unit 21 is operated and the piston rod thereof is retracted. Thereby, the lever 19 is moved from one angular position 15 to another angular position 16. Then, the hardening compaction roller head 13 'comes to the processing position, and the different R portions 2 of the main shaft 3 of the crankshaft 5 can be compacted. Lever 19 arrow 27
The pivoting movement in the direction of is not limited to the switching position described in this embodiment in any way. Similarly, it can be applied to two or more curing compaction roller heads. However, it is also meaningful to provide only one hardening roller compaction roller head 13 when applying the hardening roller 1 or 1 '.
The swiveling movement that can occur, for example via the lever 19, simplifies the tool exchange for the tool 13 or makes it easier to operate when the hardening roller 80 for the R part 2 is damaged, thus making it possible to set the hardening roller for the R part. It makes sense to help simplify the replacement of the pressure roller 80. It is likewise possible to facilitate the insertion of the workpiece by such a pivoting movement.

The support roller head 14 is also moved in the direction of the arrow 26 ', for example, by using the handle 22 from the angular position 17 in the processing position to the angular position 18
You can turn to. For this just a locking bolt
29 is pulled out, and the lever 20 is easily turned via the handle 22. In the swivel position 18, the locking bolt 29 is reinserted, where it is inserted into the hole 30 in the arm 7. At this turning position, the support roller head 14 can be replaced without difficulty. However, the lever 20 can also be formed in the embodiment of the lever 19, so that the lever 20 can also support a plurality of different support roller heads for different support configurations.

The support roller head 14 can likewise be swiveled in the direction of the arrow 26 ', for example by means of the handle 22, from an angular position 17 in the working position to another angular position 18. For this purpose, the locking bolt 29 may be pulled out, and the lever 20 can be swung without difficulty via the handle 22. In the swivel position 18, the locking bolt 29 is reinserted, where it is inserted into the hole 30 in the arm 7. At this turning position, the support roller head 14 can be replaced without difficulty. However, the lever 20 can also be formed in the embodiment of the lever 19, so that the lever 20 can also support a plurality of different support roller heads for different support configurations.

The hardening compaction device 1'according to FIG. 3 has substantially the same structure as the hardening compaction device 1 shown in FIGS. 1 and 2 in its essential structure. The arm 7 with the supporting roller head 14 pivoted on the lever 20 on the arm 7 via the hinge pin 26 has exactly the same construction as already described in FIG. This lever 7 is also hingedly connected to the arm 6'by means of pivot pins 24 and a connecting plate 23, in which case the arm 6 '.
Or the rear end 8'or 9 of the piston cylinder unit 10
Coupled to the arm, which provides a swiveling motion between the arms to provide the required rolling force.

The construction of the arm 6'is different from the arm 6 according to FIG.
In the region of the front end 11 'of the arm 6', this arm has a slider guide 37 on its underside, on which one or several sliders 35 can be provided. This one or several sliders 35 are arrows 36
Can be slid in the direction of. The slider 35 supports the hardening compaction roller heads 31, 32 and 33 in the embodiment according to FIG. Since several sliders 35 are provided in this embodiment, the hardening roller compaction roller heads 31 to 33 are connected to each other via a joint plate 38. The hardening compaction roller head 31 is in the working position 34 while the hardening compaction roller heads 32 and 33 are
Is receding.

Due to the sliding movement of the slider 35 with the hardening roller compaction roller heads 31 to 33 on the slider guide 37, the hardening roller compactor head 33 is connected to the piston cylinder unit 21 'through the arm 39 together with the slider 35 attached. ing. The advancing and retreating movements of the piston rod of this piston cylinder unit 21 'correspondingly actuate the movement of the slider 35 and move the hardening compaction roller heads 31-33 in the direction of arrow 36. Thereby, each desired curing compaction roller head 31-33 is brought to or away from the processing position 34. In each working position the hardened roller head is either mechanically locked or held in the working position 34 via an adjusting device connected to the piston of the piston cylinder unit 21 '.

In this configuration, each slider 35 can be formed as a fixed constituent member of the hardening compaction roller head to be attached. It is likewise possible to form several hardening roller compactor heads as a constituent unit, so that only one hardening roller compactor head with several working positions is present as a constituent group.

Of course, it is also possible to use the curing roller compaction roller head as the supporting roller head attached to the arm 7 as described for the lever 6 '. The arm 7 must then be formed at its second end 12 so as to correspond to the end 11 'of the only arm 6'.

However, during the rolling process, the free end 58 of the angle lever 56 is flipped high upward from the device so that the movement of the movable rolling device 50 is not hindered by the extension of the piston rod of the hydraulic cylinder 57.

(Effect of the Invention) According to the present invention, a compaction device of the type mentioned at the beginning can be applied to compaction crankshafts having various dimensions with compaction devices having compaction tools, and the main shaft of the crankshaft and the shaft for connecting rod Are configured so that they can be processed simultaneously and continuously.
