Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a deburring device and a deburring method, and more particularly to a gear deburring device that removes fine burrs and dents formed on a tooth end surface during processing of a gear.
[0002]
[Prior art]
In the grinding of gears, it is common to finish the gears by shaving and then heat-treat. In heat treatment, shot peening is performed to improve the fatigue life. At that time, burr is generated on the tooth surface, or dents are generated on the tooth surface due to interference of the heat treatment jig. There is an inconvenience.
[0003]
If such burrs and dents remain on the tooth surface, noise is generated when the gear is driven and early wear of the gear is caused.
Conventionally, in order to remove such burrs and dents on the tooth surface from the tooth surface, a deburring device that rotates while pressing a tool such as a shaving cutter against the tooth surface of the gear after heat treatment has been adopted. Has been. An example of such a deburring device is one having a structure disclosed in Japanese Patent Laid-Open No. 3-43118.
[0004]
The conventional deburring device shown in this publication includes a shaving cutter that is rotationally driven by a motor, a feed mechanism that moves the shaving cutter back and forth with respect to the gear to be processed, and a height adjustment mechanism that moves the shaving cutter up and down. It has. Further, since the gear to be machined and the shaving cutter generally have a twist angle, in order to mesh the gear to be machined and the shaving cutter, it is necessary that both are arranged with an appropriate axis crossing angle. For this reason, this deburring device has an inclination adjustment mechanism that adjusts the inclination angle of the shaving cutter with respect to the work gear.
[0005]
In a conventional deburring device, the tilt adjustment mechanism supports a shaving cutter and a connecting arm that holds a motor so as to be rotatable about a horizontal axis perpendicular to the rotation axis of the shaving cutter. The connecting arm is appropriately adjusted and fixed according to the corner.
[0006]
In order to remove the burrs and dents of the gear to be processed by this deburring device, for example, the gear to be processed is supported rotatably around the vertical axis, and the height adjusting mechanism and the feed mechanism are operated. Then, the shaving cutter is moved up and down relative to the gear to be processed. As a result, the shaving cutter is meshed with the gear to be machined. By rotating the shaving cutter by operating the motor, the tooth surface and the shaving cutter are slid while the gear to be machined is rotated. It is possible to remove burrs and dents on the tooth surface of the gear.

[0022]
For example, as shown in FIG. 3, the shaving cutter 3 has a shape in which a plurality of cutting edge grooves are provided on a tooth surface 19 of a helical gear, and is used for shaving before heat treatment. A cutter with a sharper edge than that, for example, a cutter worn by shaving is used.
[0023]
As shown in FIGS. 1 and 4, the cutter rotating mechanism 4 is housed in a holder 22 fixed on a swing base 21 described later, and is supported rotatably around a vertical axis. A spindle shaft 23 having the shaving cutter 3 fixed to the upper end thereof, a motor 24 for generating a rotational driving force transmitted to the spindle shaft 23, and a connecting shaft 25 for connecting the motor 24 and the spindle shaft 23 are provided. is doing. Universal joints 26 and 27 are arranged between the connecting shaft 25 and the motor 24 and spindle shaft 23, respectively. A spline joint 28 is provided between the connecting shaft 25 and the universal joint 26. Thus, even if the relative angle between the connecting shaft 25 and the motor 24 or the spindle shaft 23 changes, the universal joints 26 and 27 can transmit the rotational driving force of the motor 24 to the spindle shaft 23. .
[0024]
The cutter forward / reverse mechanism 5 includes a horizontally arranged ball screw 29, a motor 30 and a speed reducer 31 that apply a rotational driving force to the ball screw 29, and a linear guide 32 that extends horizontally toward the gear support mechanism 2. A first slider 33 and a second slider 34 provided so as to be movable in the horizontal direction along the linear guide 32, and a pressure transmission means 35 for connecting the first and second sliders 33, 34. It is equipped with.
[0025]
A nut 36 attached to the ball screw 29 is fixed to the first slider 33, and when the ball screw 29 is rotated by driving the motor 30, the nut 36 moves forward and backward along the ball screw 29. As a result, the first slider 33 to which the nut 36 is fixed is moved forward and backward together with the nut 36.
[0026]
The pressurizing force transmission means 35 includes a first bracket 37 fixed to the first slider 33, a second bracket 38 fixed to the second slider 34, and a pressure spring disposed therebetween. 39. Reference numeral 40 in the drawing denotes a pressure adjusting unit. By rotating the sleeve 41, the adjustment spring 42 in the sleeve 41 is expanded and contracted, and the first bracket 3. 7 To second bracket 3 8 The applied pressure transmitted to can be adjusted.
[0027]
FIG. 5 is a plan view of the pressure transmission means 35 as seen from above. According to FIG. 5, the detection plate 43 is fixed to the first bracket 37 via a connection plate 37a, and the sensor fixing plate 38b is fixed to the second bracket 38 via a connection plate 38a. The sensor fixing plate 38b is provided with a proximity sensor 44 that outputs a detection signal when the distance between the sensor fixing plate 38b and the detection plate 43 is a predetermined distance or more. As a result, when the external spring acts on the second bracket 38 to compress the pressure spring 39 and the distance from the detection plate 43 connected to the first bracket 37 is increased, the proximity sensor 44 is activated. Thus, a detection signal is output.
[0028]
As shown in FIG. 1, the cutter tilting mechanism 6 includes a motor 45 and a speed reducer 46 that generate a rotational driving force, a swing arm 47 fixed to the output shaft of the speed reducer 46, and the swing arm. Swing base fixed to the tip of 47 21 And the swing base 21 An arc-plate guide rail 48 centered on the output shaft of the speed reducer 46, and a circumferentially spaced position between the guide rail 48 in the radial direction as shown in FIG. And a cam follower 49 that contacts the surface of the guide rail 48 and guides the movement of the guide rail 48 in the circumferential direction.
[0029]
The cutter swinging mechanism 7 is composed of the same constituent members as the cutter tilting mechanism 6 and drives the motor 45 in accordance with a command signal from a controller (not shown) to center the position of the shaving cutter 3 after tilting. As described above, the shaving cutter 3 is reciprocally swung within a predetermined angle range set in advance along the same direction as the tilting direction.
[0030]
The operation of the deburring device 1 according to this embodiment configured as described above will be described below.
When the work W on which burrs and dents are formed by shot peening in the heat treatment step is conveyed by a manipulator (not shown), as shown in FIG. 2, the ejector provided in the gear support mechanism 2 The plate 16 is raised, and the work W that has been transported is placed thereon.
[0031]
The ejector plate 16 on which the workpiece W is placed is lowered, and the inner hole of the workpiece W is fitted into the boss portion 17 at the upper part of the gear support base 11. At the same time, the cylinder 12 is actuated and the work clamper 13 is lowered in the vertical direction along the linear guide 14 to press the upper surface of the work W fitted to the boss portion 17. Thereby, the work W is sandwiched and fixed between the gear support 11 and the work clamper 13. In this state, the ejector plate 16 is further lowered to leave the workpiece W. The gear support 11 and the work clamper 13 are supported by the holders 9 and 18 so as to be rotatable about the same vertical axis, so that the work W is rotatably arranged around the vertical axis, Preparation is complete.
[0032]
Next, the cutter tilting mechanism 6 is operated, and the shaving cutter 3 is moved to an angle at which the shaving cutter 3 can be engaged with the workpiece W according to the twist angle of the workpiece W and the intersection angle between the workpiece W and the shaving cutter 3. It is tilted around the output shaft of the speed reducer 46. Here, the axis of the output shaft of the speed reducer 46 is always orthogonal to the axis of the workpiece W and the axis of the shaving cutter 3.
[0033]
In this case, the rotational driving force from the motor 45 and the speed reducer 46 is applied to the connecting arm 47 and the swing base. 21 Swing the base 21 The shaving cutter 3 is tilted by being tilted together with the holder 22 fixed to. Swing base 21 Is supported by a circular arc flat guide rail 48 supported by a plurality of cam followers 49 so as to be rotatable around the output axis of the speed reducer 46, so that an excessive impact force acts on the shaving cutter 3 in the deburring operation. Even so, the cam follower 49 and the guide rail 48 can stabilize the shaving cutter 3 so as not to shake.
[0034]
Further, since the motor 24 of the cutter rotating mechanism 4 is connected to the spindle shaft 23 to which the shaving cutter 3 is fixed via the connecting shaft 25, the spline joint 28, and the universal joints 26 and 27, the cutter tilting mechanism 6 is operated. Even if the inclination angle of the shaving cutter 3 is changed, the rotational force of the motor 24 can be transmitted to the shaving cutter 3 and the shaving cutter 3 can be stably rotated.
[0035]
Next, the cutter back-and-forth moving mechanism 5 is operated, and the shaving cutter 3 in the inclined state as described above is advanced toward the workpiece W. Specifically, the ball screw 29 is rotationally driven via the speed reducer 31 by the operation of the motor 30 that constitutes the cutter forward / reverse mechanism 5, and the nut 36 attached to the ball screw 29 is directed toward the workpiece W. Can be moved in a straight line. Accordingly, the first slider 33 fixed to the nut 36 is guided by the linear guide 32 and is linearly advanced in the direction of the workpiece W.
[0036]
Since the first slider 33 and the second slider 34 are connected by the pressure transmission means 35, when the first slider 33 is advanced, the second slider is passed through the pressure transmission means 35. The applied pressure is transmitted to 34, and the second slider 34 is also moved forward.
Specifically, when the first slider 33 is moved forward from the state in which the first and second sliders 33 and 34 are stationary, the first and second brackets 37 and 38 of the pressure transmission means 35 are used. A pressure force is transmitted to the second bracket 38 by the pressurizing spring 39 disposed therebetween, and the second slider 34 is moved forward along the linear guide 32.
[0037]
Since the shaving cutter 3, the cutter rotating mechanism 4 and the cutter tilting mechanism 6 are mounted on the second slider 34, the shaving cutter 3 tilted in accordance with the twist angle of the workpiece W by the operation of the cutter tilting mechanism 6. Is moved forward until it is engaged with the workpiece W.
In this case, in order to more appropriately mesh the shaving cutter 3 and the workpiece W, the cutter rotating mechanism 4 is operated when the shaving cutter 3 and the workpiece W come into contact with each other, and the shaving cutter 3 is rotated at a low speed. However, it can be moved forward toward the workpiece W.
[0038]
When the shaving cutter 3 is properly meshed with the workpiece W and the first slider 33 is moved to a predetermined advance position, the shaving cutter 3 is pressed against the workpiece W with an appropriate pressing force by the pressure spring 39. . In this state, the cutter rotating mechanism 4 is operated and the shaving cutter 3 is rotated at a high speed, whereby the deburring operation is started.
[0039]
On the other hand, when the tooth tip of the shaving cutter 3 and the tooth tip of the workpiece W come into contact with each other and the engagement between the two is not properly performed, the first slider 33 is moved to the predetermined advance position. Further, the pressure spring 39 is compressed, and the first bracket 37 and the second bracket 38 come close to each other. Since the detection plate 43 is fixed to the first bracket 37 and the sensor fixing plate 38b is fixed to the second bracket 38, when the first bracket 37 and the second bracket 38 are close to each other, the sensor fixing plate 38b is detected. When the distance from the plate 43 is increased, and the distance is more than a predetermined distance, the proximity sensor 44 is activated, and it is detected that the shaving cutter 3 and the workpiece W are not properly meshed with each other. Then, based on this detection signal, the forward movement of the shaving cutter 3 by the cutter forward / backward moving mechanism 5 is switched to the backward movement, and after the shaving cutter 3 is once separated from the workpiece W, the meshing operation is repeated again.
[0040]
In this way, when the shaving cutter 3 is properly meshed with the workpiece W, the shaving cutter 3 rotates at a predetermined speed in a state of being pressed against the workpiece W by the pressure of the pressure spring 39. By rotating at high speed around the axis, burrs and dents existing on the tooth surface of the workpiece W are removed.
[0041]
In this state, as shown in FIG. 6, when the cutter swing mechanism 7 is operated, the shaving cutter 3 is swung back and forth over a predetermined minute angle range. That is, since the cutter swinging mechanism 7 is configured by the above-described cutter tilting mechanism 6, by further operating the motor 45 that tilts the shaving cutter 3, the shaving cutter 3 reciprocates around the position after tilting. It will be swung.
[0042]
As a result, the shaving cutter 3 can be slid on the tooth surface of the workpiece W while rotating the workpiece W meshed with the shaving cutter 3 around the vertical axis of the gear support 11, and the rotation axis of the workpiece W and It is moved along a crown formed on the tooth surface of the workpiece W by being swung around a horizontal axis perpendicular to both the rotation axes of the shaving cutter 3. Accordingly, the entire tooth surface having the crown of the workpiece W can be slid by the shaving cutter 3, and shots that are likely to be formed at the dents formed at every part on the tooth surface or at the end of the tooth surface. All burrs caused by peening can be scraped off.
[0043]
After the deburring operation is finished, the swinging operation of the shaving cutter 3 by the operation of the cutter swinging mechanism 7 is stopped, the rotational speed of the shaving cutter 3 by the cutter rotating mechanism 4 is lowered, and the cutter forward / backward moving mechanism 5 Is operated, and the shaving cutter 3 is moved backward in a direction away from the workpiece W. At this time, the shaving cutter 3 may be returned to the horizontal position by the operation of the cutter tilting mechanism 6.
[0044]
Thereafter, the work clamper 13 is lifted by the operation of the cylinder 12 to release the gripping state of the work W, and the work W is removed from the boss portion 17 by the lift of the ejector plate 16, and is transported by the manipulator. Is possible.
[0045]
As described above, according to the deburring device 1 according to the present embodiment, the shaving cutter 3 is reciprocated within a predetermined angle range while the shaving cutter 3 is engaged with the workpiece W and rotated while being pressed with an appropriate pressing force. Since the rocking is performed, the tooth surface of the workpiece W having a crown is slid by the shaving cutter 3 as a whole, and burrs can be efficiently removed.
[0046]
Further, since the shaving cutter 3 is reciprocally swung over a predetermined angular range around an axis perpendicular to both the rotation axis of the workpiece W and the rotation axis of the shaving cutter 3, the shaving cutter 3 matched to the twist direction of the tooth surface of the workpiece W is obtained. It is not necessary to strictly adjust the inclination angle. Therefore, the adjustment work when adjusting the inclination angle of the shaving cutter 3 with respect to the workpiece W having different twist angles can be easily performed. Furthermore, even when the shape of the workpiece W varies due to distortion or the like during quenching, fine adjustment of the tilt angle for each workpiece W is unnecessary, and the working time can be greatly shortened.
[0047]
In the above embodiment, the tilt angle adjustment of the shaving cutter 3 is performed by the operation of the motor 45 that constitutes the cutter tilting mechanism 6. Therefore, the tilt angle adjustment work itself that is performed manually is eliminated, and the working time can be shortened. it can.
[0048]

[0049]
According to the deburring device according to the invention of claim 2, by the operation of the motor. shaving Since the cutter can be tilted according to the torsional direction of the gear to be processed, it is only necessary to command the twisting direction to the motor when deburring the to-be-processed gear with different torsion angles. There is an effect that the required work time can be shortened.
[0050]
In this case, in the deburring device of the present invention, shaving The cutter shaving Since it is swung over a predetermined angular range around an axis perpendicular to the axis of the cutter and the gear to be processed, shaving Adjustment of the tilt angle of the cutter is relatively simple and does not require strict fine adjustment. Therefore, even when the tooth surface shape of the gear to be machined varies due to distortion caused by heat treatment or the like, it is not necessary to individually adjust the inclination angle, and the working time can be shortened.
