[0039] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0040] like Figure 1-4 As shown, the present invention provides an efficient rough processing device for an end gear disc, the device comprising: a processing table 1, a clamping mechanism 2 and a grinding mechanism;

[0041] The clamping mechanism 2 includes: a fixed block 201, a first clamping block 202 and a second clamping block 203; wherein,

[0042] The middle part of the processing table 1 protrudes upward to form a truncated cone portion for positioning the end toothed disc, and the upper end of the processing table 1 is provided with a number of No. 1 clamping blocks 202 which can spread outward in its radial direction to abut against the inner wall of the end toothed disc at equal intervals along the circumferential direction of the truncated cone portion, and each of the No. 1 clamping blocks 202 is vertically fixed with a fixing rod 21 which can partially extend into the interior of the processing table 1 at the bottom end, and a fixing block 201 is horizontally fixed at the bottom end of each of the fixing rods 21, and a power mechanism 3 which can drive all the fixing blocks 201 to move along the radial direction of the truncated cone portion is provided inside the processing table 1, and a No. 2 clamping block 203 which can abut against the end toothed disc can be lifted and lowered above each of the No. 1 clamping blocks 202, and a grinding mechanism which can move along the radial direction of the end toothed disc for grinding it is movably provided on one side of the processing table 1.

[0043] In the above scheme, when in use, the inner circle of the broken tooth disk to be processed is horizontally passed through the truncated cone portion and placed on the processing table 1, and the power mechanism 3 drives all the fixed blocks 201 along the radial direction of the truncated cone portion to drive all the No. 1 clamping blocks 202 toward the inner wall of the end tooth disk until all the No. 1 clamping blocks 202 are all against the end tooth disk, so as to limit the end tooth disk in the horizontal direction by multiple No. 1 clamping blocks 202 to prevent the end tooth disk from moving in the horizontal direction during the grinding process and affecting the grinding effect.

[0044] While all the No. 1 clamps 202 are moving in the horizontal direction and abutting against the end toothed disc, they can drive the No. 2 clamps 203 arranged thereon to move toward the inner wall of the end toothed disc. All the No. 2 clamps 203 can move to above the steps on the inner wall of the end toothed disc and drive all the No. 2 clamps 203 to descend in the vertical direction until they abut against the steps of the end toothed disc, so as to limit the end toothed disc in the longitudinal direction and prevent it from moving in the longitudinal direction during the grinding process, thereby affecting the grinding effect.

[0045] After the end toothed disc to be processed is clamped and fixed, the grinding mechanism is started to move along the circumferential direction of the end toothed disc, so that the grinding mechanism grinds each tooth groove on the end toothed disc one by one.

[0046] In summary, the present invention drives all the fixed blocks 201 through the power mechanism 3 to drive all the No. 1 clamping blocks 202 and all the No. 2 clamping blocks 203 to move along the moving direction of the end gear disk, and drives all the No. 2 clamping blocks 203 to rise and fall in the vertical direction, so that the clamping mechanism 2 can clamp and fix end gear disks of different sizes, without the need to replace the clamping mechanism, thus saving time and effort and improving its practicality.

[0047] In a preferred embodiment of the present invention, the power mechanism 3 includes: a screw rod 301, a round table slider 302 and a reset member 303; wherein,

[0048] A screw rod 301 is vertically and rotatably arranged at the center position inside the processing table 1, and a truncated table slider 302 is vertically fixedly arranged on the screw rod 301, and the side wall of the truncated table slider 302 abuts against the end of each fixed block 201. A plurality of reset members 303 corresponding to all the fixed blocks 201 are horizontally fixedly arranged on the inner wall of the processing table 1 at equal intervals along its circumferential direction, and each reset member 303 is connected to the corresponding fixed block 201.

[0049] In the above scheme, when in use, the screw rod 301 is rotated to drive the conical slider 302 to rise and fall along its axis. When the conical slider 302 descends, its inclined surface can push all the fixed blocks 201 abutting on its surface in the horizontal direction and drive all the No. 1 clamping blocks 202 and the No. 2 clamping blocks 203 to move toward the end gear disk until they abut against its inner wall, and drive all the No. 2 clamping blocks 203 to descend in the vertical direction and abut against the step of the end gear disk, thereby clamping and fixing the end gear disk.

[0050] When it is necessary to release the clamping relationship between the clamping mechanism 2 and the end gear disk, all the No. 2 clamping blocks 203 are driven to rise in the vertical direction to separate from the end gear disk, and the screw rod 301 only needs to be rotated in the reverse direction to drive the truncated cone slider 302 to rise along its axis. Under the action of the corresponding reset member 303, each of the fixed blocks 201 can drive the No. 1 clamping block 202 and the No. 2 clamping block 203 located above it to move in the opposite direction toward the screw rod 301, so that all the No. 1 clamping blocks 202 are separated from the end gear disk, thereby completing the release of their clamping relationship.

[0051] In a preferred embodiment of the present invention, each of the reset members 303 comprises: a reset seat, a reset spring, a reset rod and a reset plate; wherein,

[0052] A reset plate is horizontally and movably arranged inside the reset seat with an opening facing the screw rod 301 and horizontally fixed on the processing table 1, and a reset rod is horizontally fixed on one side of the reset plate and can extend from the opening of the reset seat and fixed on the corresponding fixed block 201, and a reset spring is horizontally fixed on the other side of the reset plate, and the other end of the reset spring is fixed on the reset seat.

[0053] In the above scheme, the screw rod 301 is rotated to drive the truncated cone slider 302 to rise and fall along its axis. When the truncated cone slider 302 descends, its inclined surface can push all the fixed blocks 201 abutting on its surface in the horizontal direction and drive all the No. 1 clamping blocks 202 and the No. 2 clamping blocks 203 to move toward the end gear disk until they abut against its inner wall. At the same time, each of the fixed blocks 201 is pushed away from the screw rod 301 by the reset rod and compresses the corresponding reset spring to make it in a compressed state, and then drives all the No. 2 clamping blocks 203 to descend in the vertical direction and abut against the step of the end gear disk, thereby clamping and fixing the end gear disk.

[0054] When it is necessary to release the clamping relationship between the clamping mechanism 2 and the end gear disk, all the No. 2 clamping blocks 203 are driven to rise in the vertical direction to separate from the end gear disk, and the screw rod 301 only needs to be rotated in the reverse direction to drive the truncated cone slider 302 to rise along its axis. Under the action of the corresponding reset spring, each of the fixed blocks 201 can drive the No. 1 clamping block 202 and the No. 2 clamping block 203 located above it to move in the opposite direction toward the screw rod 301, so that all the No. 1 clamping blocks 202 are separated from the end gear disk, thereby completing the release of their clamping relationship.

[0055] In a preferred embodiment of the present invention, a No. 1 motor is vertically fixedly disposed on the top of the processing table 1, and the output shaft of the No. 1 motor is coaxially connected to the screw rod 301 through a coupling.

[0056] In the above scheme, the first motor is started to drive the screw rod 301 to rotate, thereby driving the truncated cone slider 302 threadedly connected thereto to move up and down along its axis.

[0057] In a preferred embodiment of the present invention, the device further comprises a lifting mechanism for driving all the second clamping blocks 203 to lift and lower in the vertical direction, the lifting mechanism comprising: a vertical rod 4, a support block 5, a longitudinal spring 6 and a lifting ring 7; wherein,

[0058] A vertical pole 4 is vertically fixed at the bottom end of each No. 2 clamping block 203, and the bottom end of each vertical pole 4 passes through the corresponding fixed block 201 and extends to the bottom thereof where a support block 5 is horizontally fixed. A longitudinal spring 6 is sleeved on each vertical pole 4 between the fixed block 201 and the support block 5, and both ends of the longitudinal spring 6 are respectively fixed on the fixed block 201 and the support block 5. A lifting ring 7 is horizontally and liftably arranged inside the processing table 1 between all the fixed blocks 201 and the support blocks 5, which can abut against all the support blocks 5 when descending.

[0059] In the above scheme, the lifting ring 7 is driven to descend in the vertical direction so that it abuts against all the support blocks 5, and the lifting ring 7 is continued to be driven to descend in the vertical direction to push all the support blocks 5 to descend in the vertical direction together, so as to drive all the No. 2 clamping blocks 203 to descend together and abut against the end gear disk, thereby clamping the end gear disk to prevent movement during the grinding process, and each support block 5 compresses the corresponding longitudinal spring 6 during the descending process to make it in a compressed state.

[0060] When the grinding is completed, when it is necessary to contact the clamping relationship of all the No. 2 clamping blocks 203 with the end gear disk, it is only necessary to drive the lifting ring 7 to rise in the vertical direction, and all the support blocks 5, under the resetting action of the corresponding longitudinal springs 6, can drive each of the support blocks 5 and the No. 2 clamping blocks 203 fixed thereon by the fixing rod 21 to rise in the vertical direction and separate from the end gear disk to restore to their original positions, thereby completing the clamping relationship with the end gear disk.

[0061] In a preferred embodiment of the present invention, the lifting mechanism further includes a third electric telescopic rod 14 for driving the lifting ring 7 to lift; wherein,

[0062] At least two No. 3 electric telescopic rods 14 are fixedly arranged at intervals and vertically penetrate the bottom end of the processing table 1 , and the telescopic end of each of the No. 3 electric telescopic rods 14 is fixed on the lifting ring 7 .

[0063] In the above scheme, the lifting ring 7 is driven to lift in the vertical direction by the third electric telescopic rod 14, so that the lifting ring 7 can push the support block 5 through the fixing rod 21 to drive the second clamping block 203 to descend in the vertical direction and abut against the end gear disk during the descending process, thereby clamping and fixing the end gear disk. When the lifting ring 7 rises, the second clamping block 203 rises in the vertical direction to separate from the end gear disk under the resetting action of the longitudinal spring 6, thereby releasing the clamping relationship with the end gear disk.

[0064] In a preferred embodiment of the present invention, the grinding mechanism includes: a moving plate 8, a lifting platform 9, a motor box 10, a grinding tool 11, a first electric telescopic rod 12 and a second electric telescopic rod 13; wherein,

[0065] A movable plate 8 capable of moving along its circumferential direction is horizontally and movably arranged on one side of the processing table 1, and a lifting platform 9 is horizontally and movably arranged on the upper end of the movable plate 8 through a No. 1 electric telescopic rod 12, and a motor box 10 capable of moving the rod toward the end gear disk is horizontally and movably arranged on the upper end of the lifting platform 9 through a No. 2 electric telescopic rod 13, and a No. 2 motor is horizontally fixedly arranged inside the motor box 10, and the output shaft portion of the No. 2 motor extends from the motor box 10 and is coaxially fixedly provided with a grinding tool 11.

[0066] In the above scheme, the No. 1 electric telescopic rod 12 is vertically fixed on the movable plate 8, and its telescopic end is fixed on the lifting platform 9, while the No. 2 electric telescopic rod 13 is horizontally fixed on the upper end of the lifting platform 9, and its telescopic end is fixed in the motor box 10.

[0067] When in use, the movable plate 8 is driven to move along the circumferential direction of the processing table 1 to adjust the grinding position of the end tooth disc of the grinding mechanism, and the height of the lifting platform 9 is adjusted by the No. 1 electric telescopic rod 12 so that the grinding tool 11 set on the lifting platform 9 can grind each tooth groove on the end tooth disc. In addition, the No. 2 electric telescopic rod 13 is used to drive the grinding tool 11 to move in the horizontal direction to adjust the position of the grinding tool 11 in the horizontal direction, so that the grinding tool 11 can completely and better grind the tooth grooves on the end tooth disc.

[0068] In addition, the first electric telescopic rod 12, the second electric telescopic rod 13 and the third electric telescopic rod 14 can be cylinders or servo electric cylinders.

[0069] In a preferred embodiment of the present invention, the device further comprises a driving mechanism 20 for driving the movable plate 8 to move along the circumferential direction of the processing table 1, wherein the driving mechanism 20 comprises: a third motor, a driving gear and a driven gear; wherein,

[0070] A column 17 is vertically arranged at the center position of the bottom end of the processing table 1, a base 16 is horizontally fixedly arranged at the bottom end of the column 17, a rotating seat 18 is horizontally and rotatably arranged on the column 17, an L-shaped support rod 19 is horizontally fixedly arranged on the rotating seat 18, the top end of the support rod 19 is fixed on the moving plate 8, a driven gear is coaxially fixedly arranged on the rotating seat 18, and a No. 3 motor is vertically fixedly arranged on the bottom end of the processing table 1 located next to the driven gear, and a driving gear meshing with the driven gear is coaxially fixedly arranged on the output shaft of the No. 3 motor.

[0071] In the above scheme, when in use, the third motor is started to drive the driving gear on its output shaft to drive the driven gear meshing with it to rotate, and then the rotating seat 18 is driven through the support rod 19 to drive the moving block 8 to move along the circumferential direction of the processing table 1, thereby driving the grinding mechanism to move along the circumferential direction of the end toothed disk clamped and fixed at the upper end of the processing table 1, so that the grinding mechanism can perform grinding operations on each tooth on the end toothed disk, thereby improving the grinding effect.

[0072] In a preferred embodiment of the present invention, at least one ball capable of abutting against the truncated table slider 302 is rotatably provided at the end of each of the fixed blocks 201 .

[0073] In the above scheme, the ball bearings at the end of each fixed block 201 can always abut against the conical slider 302, so that when the conical slider 302 is lifted and lowered in the vertical direction, the sliding friction between the fixed block 201 and the conical slider 302 can be converted into rolling friction, thereby reducing the friction between the two and extending the service life of the two.

[0074] In a preferred embodiment of the present invention, two guide rods 15 are vertically fixed inside the processing table 1 located on both sides of the screw rod 301, and guide holes for the two guide rods 15 to pass through are provided at intervals and vertically penetrated on the truncated table slider 302.

[0075] In the above solution, the truncated table slider 302 is assembled on the two guide rods 15 through the guide holes.

[0076] When in use, the coordinated use of the guide rod 15 and the guide hole on the truncated cone slider 302 can ensure that the screw rod 301 can drive the truncated cone slider 302 threadedly connected thereto to move up and down smoothly and reliably along its axis during rotation.

[0077] In summary, the efficient rough processing device for the end gear disc provided by the present invention overcomes the problem that the clamp used in the prior art for processing the end gear disc can only clamp and fix the end gear disc of one size, and when processing end gear discs of different sizes, it is necessary to replace the clamp of the corresponding size to clamp the end gear disc, which reduces its practicality.
