Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention can be used in either a high-speed planetary rotating barrel polisher or a rotary barrel polisher, and in both cases the barrel operates as a three-stage action barrel. Regarding polishing equipment.

(Prior art and problems to be solved) Conventional high-speed planetary rotating barrel polishing has been widely used due to its high processing efficiency, but it is difficult to roughen the surface of processed workpieces using abrasive materials charged into the barrel tank. Once a limit is reached and a certain level of roughness is reached, no further improvement can be expected. On the other hand, rotating barrel polishing has a low processing efficiency, but is characterized by greatly improving the surface roughness of the processed workpiece.

Therefore, when two processes of rough finishing and gloss finishing are required, the rough finishing is performed using a high-speed planetary rotating barrel polishing machine, and then the abrasive is replaced with a glossy polishing material for glossy finishing, or the high-speed planetary rotating barrel polishing machine is used. After rough finishing is performed in the machine, the contents are transferred to a rotating barrel tank and polishing is carried out in a separate rotating barrel, so replacing the contents takes time and requires a lot of effort. Furthermore, when a high-speed planetary rotating barrel polishing machine and a rotating barrel polishing machine are used, the surface roughness is improved, but the installation area is large and the cost is high.

(Means for Solving the Problems) However, according to the present invention, the barrel tank is attached to the turret via a gear housing so that it can rotate and revolve (that is, perform planetary rotation motion), and the barrel The tank was made to be able to rotate around its axis while being fixed to the turret, so
Not only can one device use high-speed planetary rotating barrel polishing method and rotary barrel polishing method as needed, but the shape of the barrel can be modified to perform three-stage action in either case. You can choose.

In addition, the turret is rotated and revolved in a high-speed planetary manner to roughly finish the workpiece, and the barrel tank containing the workpiece, abrasive material, and if necessary, water and compound is then rotated and revolved. By rotating the machine, the workpiece can be finished with a glossy finish using the same abrasive material. In addition, in contrast to this method, after polishing by the rotating barrel polishing method, it is possible to perform polishing by the high-speed planetary rotating barrel polishing method using the same abrasive material. In this way, two polishing steps with different properties can be performed successively without replacing the contents (hereinafter referred to as mass).

That is, according to this invention, a turret is fixed to a turret shaft rotatably installed on the fuselage body, and a plurality of gear housing shafts are rotatably attached to the same circumference of the periphery of the turret parallel to the turret shaft, The gear housing shaft fixes the gear housing and is connected to a drive device, and a plurality of barrel shafts protrude from inside the gear housing so as to be rotatable radially in a direction perpendicular to the turret shaft. The barrel polishing device is characterized in that a barrel tank is attached to each of the barrels, and the turret shaft and barrel shaft are connected to different drive devices, respectively, and the drive device for the barrel shaft is installed in each gear housing parallel to the turret shaft. The present invention is characterized in that it is comprised of a large bevel gear fixed to the rotating shaft of an installed rotary motor and a small bevel gear fixed to the barrel shaft. The driving device for the barrel shaft is linked by a rotary motor installed on the fuselage, and is connected to a large bevel gear fixed to a rotating shaft rotatably installed in a gear housing parallel to the turret shaft, and fixed to the barrel shaft. The shape of the barrel barrel is such that the surface fixed to the barrel axis is a square that is perpendicular to the barrel axis, and the surface that is parallel to the barrel axis and that is the square is It is characterized by having square surfaces of the same size that are perpendicular to each other.

Further, in this invention, a plurality of turrets of the gear housing are rotatably attached to the same circumference, and a plurality of barrel barrels are attached radially to each of the gear housings, so that a multi-vessel type can be achieved with an extremely simple structure. They succeeded in obtaining a barrel polishing device.

(Example) Next, details of the present invention will be explained with reference to the attached drawings. FIG. 1 is a partially sectional front view of an apparatus for implementing the present invention, and FIG. 2 is a partially sectional plan view. That is, the casing 1 is a hollow box made of an iron plate, and the turret shaft 2 is fixed to the casing 1 by a bearing 3,
It is mounted so that it can rotate relative to 4. A main pulley 40 is fixed to the lower end of the turret shaft 2, and turrets 5, 5a are fixed to the center using ETP bushings (manufactured by Miki Pulley Co., Ltd.). Sprocket 6 is loosely fitted. Turret 5, 5a
A plurality of bearings 7, 7a are mounted on the same circumference of the turret at equal intervals. bearing 7,
Both shafts 9, 9a of a gear housing 8 are fitted into the shaft 7a in parallel with the turret shaft 2, and the gear housing 8 is rotatably mounted. A geared motor 10 for rotational motion is installed in the gear housing 8 in parallel with the turret shaft 2, and a large bevel gear 12 is fixed to the rotating shaft 11 of the geared motor 10. It meshes with the small bevel gears 13. The small bevel gear 13 has a barrel shaft 1
4 are attached radially in a direction perpendicular to the turret shaft 2, protrude outward from the side surface of the gear housing 8, and a barrel tank 15 is attached thereto. The barrel tank 1
5 is rotatably supported by a rotating shaft 16 mounted symmetrically to the barrel shaft 14. The rotating shaft 16 is supported by a support piece 1 attached to the gear housing 8.
Supported by 7. The main pulley 4
0 is rotated via a motor 18 with a centrifugal reduction gear, a pulley 19, and a V-belt 20 fixed to the fuselage. Further, one of the multi-row sprockets 6 is interlocked with a fine movement geared motor 22 via a chain 21. A sprocket 23 is fixed to the upper shaft 9 of the gear housing 8, and the sprocket 23 is interlocked with the multi-row sprocket 6 by a chain 24. As shown in FIGS. 1, 2, 4, and 5, the shape of the barrel tank 15 is such that the surfaces 28a and 28b fixed to the barrel shaft 14 are squares perpendicular to the barrel shaft 14, and parallel, the surfaces 28a, 2
8b and a square surface 29 of the same size that is perpendicular to each other.
a, 29b, 29c, 29d, 29e, 29f,
It is desirable to have 29g and 29h. In this way, the top view, elevation view, and side view of the barrel shaft will have the same shape as shown in the figure, and even in the case of a rotating barrel (rotation around the barrel shaft 14), a high-speed planetary rotating barrel can be used. Even in the case (planetary rotation with the revolution axis as the turret axis 2 and the rotation axis as the axis 9), the slope shown in the figure becomes a so-called three-stage action barrel that performs an appropriate stirring action, and has the effect of improving polishing efficiency. In the figure, 25 is a lid of the barrel tank 15. Note that 26 and 27 are current collectors for sending electricity to the geared motor 10 for rotational motion.

The operation of the present invention will be explained below according to the structure of the embodiment described above. According to the apparatus of the present invention, only high-speed planetary rotating barrel polishing, only rotating barrel polishing, continuous rotating barrel polishing after high-speed rotating barrel polishing, high-speed planetary rotating barrel polishing continuously after rotating barrel polishing, and simultaneous combination of high-speed rotating and rotation Although various polishing methods such as the following can be performed, continuous rotating barrel polishing will be described here rather than high-speed rotating barrel polishing, which is the easiest to understand this invention.

A predetermined amount of the workpiece, abrasive material, water and compound if necessary are added into the barrel tank 15, and the lid 25 is attached and sealed. When all the barrel tanks 9 (in this embodiment, there are 16 tanks) have been prepared, the motor 18 with a centrifugal speed reducer is started. At this time, it is assumed that the fine movement geared motor 22 and the rotational movement geared motor 10 are stopped. When the motor 18 is started, the turrets 5 and 5a are moved to the second position.
As shown in the figure, it rotates in the direction of arrow a, the barrel tank 15 is turned around the turret shaft 2 together with the gear housing 8, and the shaft 9 is rotated by the chain 21 in the direction of arrow b in the figure. The ratio n/N between the revolution number N and the rotation number n of the barrel tank 15 can be appropriately selected by adjusting the rotation speed of the geared motor 22 for fine movement. It is optimal to choose N to be -1. In addition, the number of rotations of the barrel tank 15 in this case is 60 to 200/√2 revolutions per minute, optimally 100 to 200/min, when the revolution radius of the barrel tank (gear housing 8) is R (m).
Good results can be obtained by selecting 160/√2 rotations. Since the barrel tank 15 (gear housing 8) revolves around the turret shaft 2 and rotates around the shaft 9, the mass in the barrel tank 15 flows centrifugally, and the workpiece is subjected to high-speed planetary rotation barrel polishing.

In the device of this invention, when the barrel tank is rotated horizontally as shown in Figs. 1 and 2, the mass gradually rises toward the outer circumference of the inner wall of the barrel tank at the same time as the start. It has the advantage of less impact when starting and stopping, but
It is also possible to rotate the turrets 5, 5a vertically, that is, the barrel tank 15 vertically. When the first step is completed, the motor 19 is stopped. This stop occurs when the proximity switch detects the dog on the turret.

Next, the geared motor 10 for rotational motion is started, and the rotating shaft 11 and the large bevel gear 12 are rotated. As a result of this rotation, the small bevel gear 13 and the barrel tank 14 that mesh with the large bevel gear 12 rotate as shown by arrow c in FIG. 1, the barrel tank 15 rotates in the vertical direction, and the workpiece rotates normally. Barrel polishing is performed. The rotation speed of this barrel should be 15 to 30/√2 revolutions per minute, optimally 18 to 25/√2 revolutions per minute, when the maximum inscribed circle radius of the barrel tank is r(m). is obtained. When the second step is completed, the geared motor 10 is stopped.

Next, if the position of the barrel tank 15a of the A station in Fig. 2 is set as the working position, first, the barrel tank 1
Remove the lid 25 (Figs. 1 and 3) of 5a,
The barrel tank 1 is driven by the geared motor 10.
5a is rotated as shown by arrow c (Fig. 2) to discharge the contents onto a selection device (not shown), and after loading the next unprocessed workpiece and abrasive material, etc., the lid is closed. 25
Tighten. Next, the geared motor 22 for fine movement was driven to turn the barrel tank 15b in the direction of arrow d (in Fig. 2) and stop it at the working position, and the same operation as above was repeated to complete the barrel tank 15d. Then, drive the motor 18 with a centrifugal speed reducer and
Turn the barrel tank of the station to the A station position and stop, repeat the same operation as above, and when all the operations of the barrel tank of the B station are completed, repeat the same operation with the C station and the D station in order to complete one cycle. ends.

Figure 3 shows another embodiment in which the barrel shaft is interlocked with one rotary motor installed in the fuselage, and like the embodiments in Figures 1 and 2, each gear housing is No need to install a motor.

Since the structure other than the barrel shaft drive device is the same as that shown in FIGS. 1 and 2, the same parts are given the same numbers and only the rotary barrel polishing operation will be described.

A large bevel gear 32 is attached to the upper end of the rotating shaft 31 that is inserted into the
Attach the sprocket 36 to the lower end of the sprocket. The large bevel gear 32 is a small bevel gear 1 fixed to the barrel tank 14.
It seems to mesh with 3. Said sprocket 3
6 and a multi-row sprocket 34 loosely fitted to the turret shaft 2 is a chain 35. Further, one of the sprockets 34 is linked with a geared motor 30 for rotational motion installed in the body 1 via a chain 33. That is, in order to perform rotary barrel polishing, first the geared motor 30 for rotary motion is started. Due to this start, the multi-row sprocket 34 moves from the stopped turret shaft 2.
The rotating shaft 31 in each gear housing 8 rotates. Therefore, the small bevel gear 1 meshing with the large bevel gear 32
3 and the barrel tank 14 are rotated as indicated by the arrow c in FIG. 3, the barrel shaft 15 is rotated in the vertical direction, and the workpiece is subjected to normal rotary barrel polishing. The other operations are the same as those in the embodiment shown in FIGS. 1 and 2, and will therefore be omitted.

In the above embodiment, high-speed planetary rotating barrel polishing and rotary barrel polishing were carried out separately, but it is also possible to drive the centrifugal motor and the rotary motor at the same time to create more complex movements for the contents in the barrel tank. It can also be used to polish workpieces. Furthermore, in the above embodiment, the case where the apparatus of the present invention is used for polishing has been described, but it is clear that it can be used for purposes other than polishing, such as stirring, crushing, chemical operations, etc., and this does not fall within the technical scope of the present invention. be. Furthermore, the shape of the barrel used in the apparatus of the present invention may be spherical or the like in addition to the shapes shown in FIGS. 4 and 5.

(Effects of the Invention) As described above, the present invention not only can be used for either a high-speed planetary rotating barrel polishing machine or a rotary barrel polishing machine, but can also be configured to have a three-stage action barrel in either case. A wide variety of polishing operations can be performed with one machine. In addition, when the turret is rotated horizontally, the barrel tank is rotated horizontally in high-speed planetary rotating barrel polishing, which has the advantage that there are no dents, chips, or cracks on the workpiece.
