When processing and chamfering automobile motor magnetic tiles, grinding and chamfering processing devices are required, such as magnetic tile grinders, which are one of the chamfering processing devices.

[0046] The present invention discloses a method for using a device for processing and chamfering automobile motor magnetic tiles, comprising the following steps: when grinding and chamfering a large number of automobile motor magnetic tiles 7, firstly, two automobile motor magnetic tiles 7 are clamped and fixed to two clamping parts 6 respectively; then, the telescopic rod of the second electric cylinder 304 is controlled by the controller 201 to retract downward, thereby moving the lifting plate 303, the connecting slide rod 302, the lifting frame 301, the grinding and chamfering mechanism 4 and the automatic locking mechanism 10 downward in a straight line, until the grinding roller 402 in the grinding and chamfering mechanism 4 reaches a suitable grinding height, the telescopic rod of the second electric cylinder 304 can be controlled to stop operating; then, the lifting plate 303, the connecting slide rod 302, the lifting frame 301, the grinding and chamfering mechanism 4 and the automatic locking mechanism 10 are controlled to retract downward in a straight line, and then the grinding roller 402 in the grinding and chamfering mechanism 4 reaches a suitable grinding height, and then the telescopic rod of the second electric cylinder 304 is controlled to stop operating; then, the lifting plate 303, the connecting slide rod 302, the lifting frame 301, the grinding and chamfering mechanism 4 and the automatic locking mechanism 10 are controlled to retract downward in a straight line, and then ... The device 201 controls the telescopic rod of the first electric cylinder 203 to extend downward, thereby driving the L-shaped transparent baffle 204 to move linearly downward until the L-shaped transparent baffle 204 is completely closed; then the grinding motor 403 is started through the controller 201, thereby driving the active pulley, the driven pulley and the grinding roller 402 to rotate, and then the driving motor 404 is started through the controller 201, so that the driving motor 404 drives the reciprocating screw 405 to rotate, and then the screw nut 406 drives the reciprocating sliding seat 401 and the grinding roller 402 to move back and forth left and right under the action of the spiral groove on the reciprocating screw 405, thereby completing the grinding and chamfering operation of the automobile motor magnetic shoe 7.

[0047] The working principle of this embodiment is as follows: when grinding and chamfering a large number of automobile motor magnets 7, firstly, two automobile motor magnets 7 are clamped and fixed to the two clamping parts 6 respectively, and then the telescopic rod of the second electric cylinder 304 is controlled to retract downward by the controller 201, thereby moving the lifting plate 303, the connecting slide rod 302, the lifting frame 301, the grinding and chamfering mechanism 4 and the automatic locking mechanism 10 downward in a straight line, until the grinding roller 402 in the grinding and chamfering mechanism 4 reaches a suitable grinding height, the telescopic rod of the second electric cylinder 304 can be controlled to stop operating, and before the grinding roller 402 reaches a suitable grinding height, the lower ends of the two tightening teeth 1003 are in close contact with the upper side of the outer peripheral surface of the limit gear 605, so that the limit gear 605 and the clamping screw 603 are effectively locked, thereby preventing the clamping screw 603 and the clamping block 604 from loosening.

[0048] Then, the controller 201 controls the telescopic rod of the first electric cylinder 203 to extend downward, thereby moving the L-shaped transparent baffle 204 downward in a straight line until the L-shaped transparent baffle 204 is completely closed. When the L-shaped transparent baffle 204 is completely closed, the lower end of the L-shaped transparent baffle 204 is inserted into a strip-shaped groove 502 on the rear side of the upper end surface of the rotating disk 5, thereby sealing the front side of the housing cover 2.

[0049] Then, the grinding motor 403 is started through the controller 201, thereby driving the active pulley, the driven pulley and the grinding roller 402 to rotate, and then the driving motor 404 is started through the controller 201, so that the driving motor 404 drives the reciprocating screw 405 to rotate, and then the screw nut 406 drives the reciprocating sliding seat 401 and the grinding roller 402 to move back and forth left and right under the action of the spiral groove on the reciprocating screw 405, thereby completing the grinding and chamfering operation of the automobile motor magnetic shoe 7.

[0050] When the rear automobile motor magnet 7 is chamfered, the staff can control the telescopic rod of the first electric cylinder 203 to retract upward through the controller 201, thereby moving the L-shaped transparent baffle 204 upward in a straight line to open the L-shaped transparent baffle 204. Then, the staff will step on the double foot switch 202 with their feet to control the telescopic rod of the third electric cylinder 801 to extend. When the telescopic rod of the third electric cylinder 801 is extended forward to the limit position, the driving rack 802 will drive the transmission gear 803 to rotate 180 degrees clockwise, and then the rotating disk 5, the two clamping parts 6 and the two automobile motor magnets 7 will be rotated 180 degrees through the vertical rotating shaft 501, so that the positions of the two automobile motor magnets 7 are switched, and then At this time, the L-shaped transparent baffle 204 is closed, and the grinding and chamfering operation is continued on the current rear automobile motor magnet 7 through the grinding and chamfering mechanism 4; after the rear automobile motor magnet 7 is ground and chamfered, the staff can step on the other switch of the double foot switch 202 with their feet to control the retraction movement of the telescopic rod of the third electric cylinder 801. When the telescopic rod of the third electric cylinder 801 is retracted to the extreme position, the driving rack 802 will drive the transmission gear 803 to rotate counterclockwise by 180 degrees, and then the vertical rotating shaft 501 will drive the rotating disk 5, the two clamping parts 6 and the two automobile motor magnets 7 to rotate by 180 degrees, so that the positions of the two automobile motor magnets 7 are switched again, and such reciprocating operation can improve production efficiency.
