In each group of fixed plates 21, a motor 1 22 is fixedly installed on the outer side of one fixed plate 21. The two motors 1 22 are respectively fixed to one end of the screw 1 23 and the bidirectional screw 2 24, and the rotation of the screw 1 23 and the bidirectional screw 2 24 is driven by the motor 1 22.

[0024] refer to Figure 1-2 The surface thread of the lead screw 1 23 is provided with a slider 3 25, and the slider 3 25 slides on the outer side of the support plate 2. A telescopic cylinder 26 is fixedly installed on the outer side of the slider 3 25, and a motor 3 27 is fixedly installed on the lower end surface of the piston rod of the telescopic cylinder 26. A grinding wheel 28 is fixedly installed on the surface of the output shaft of the motor 3 27, and the grinding wheel 28 can grind the tooth groove of the gear 4.

[0025] refer to Figure 1-2 A bidirectional lead screw 24 is rotatably provided between a group of fixed plates 21 below. The surface thread of the bidirectional lead screw 24 is provided with a slider 1 241 and a slider 2 245. The slider 1 241 and the slider 2 245 are respectively arranged in different thread grooves of the bidirectional lead screw 2 24, and the slider 1 241 and the slider 2 245 are both slidably provided on the outer side surface of the support plate 2. The bidirectional lead screw 24 is driven to rotate by the motor 1 22, thereby driving the slider 1 241 and the slider 2 245 to move relative to each other.

[0026] refer to Figure 1-3 A mounting bracket 242 is fixedly installed on the outer side of the slider 1 241, and a motor 243 is fixedly installed inside the mounting bracket 242. A clamping plate 1 244 is fixed to the outer end of the output shaft of the motor 243 by bolts, and a support tube 2441 is fixed on the outer side of the clamping plate 1 244. The diameter of the support tube 2441 is the same as the diameter of the center hole of the gear 4, which is used to improve the clamping effect of the gear 4.

[0027] refer to Figure 1-3 The outer side surface of the slider 245 is provided with a through hole 2453 with the same diameter as the support tube 2441, which is convenient for the support tube 2441 to pass through. An annular groove 2451 is provided around the through hole 2453, and a clamping plate 2452 is rotatably installed in the annular groove 2451. The clamping plate 1 244 and the clamping plate 2 2452 can be used together to clamp the gear 4.

[0028] refer to Figure 3 The outer sides of the first and second clamping plates 244 and 2452 are fixedly provided with an annular rubber pad 29, and the surface of the rubber pad 29 is provided with anti-slip grooves.

[0029] Specifically, when the rotation of the two-way screw 24 drives the slider 1 241 and the slider 2 245 to move relative to each other, the support cylinder 2441 passes through the center hole of the gear 4 and the through hole 2453 of the slider 2 245 to support the gear 4, and then the rubber pads 29 on the outer sides of the splint 1 244 and the splint 2 2452 will contact the two side surfaces of the gear 4. As the two-way screw 24 rotates, the splint 1 244 and the splint 2 2452 on both sides complete the clamping of the gear 4 through the rubber pads 29, wherein the rubber pads 29 can protect the surface of the gear 4 to avoid excessive clamping force, which will cause damage to the surface of the gear 4. At the same time, the rubber pads 29 can also absorb vibrations during the grinding process to improve the processing accuracy of the gear 4.

[0030] refer to Figure 1 and Figure 4 The upper surface of the bottom plate 1 is symmetrically fixed with supports 31 near the support plate 2, and a rotating shaft 311 is rotatably installed between the two supports 31. A motor four 32 is fixedly installed on the outer side of one side support 31, and the output shaft of the motor four 32 is fixed to one end of the rotating shaft 311. A sleeve 312 is fixedly installed on the surface of the rotating shaft 311 by bolts, and a plurality of brushes 313 are fixedly provided on the surface of the sleeve 312 in a ring shape. The rotation of the rotating shaft 311 is driven by the motor four 32 to drive the brush 313 to clean the tooth groove position of the gear 4, which can effectively remove metal debris attached to the inner wall of the tooth groove after grinding.

[0031] refer to Figure 1 and Figure 4 A support frame 33 is provided next to the support 31, and the support frame 33 is fixedly mounted on the upper surface of the base plate 1, and the support frame 33 is arranged in an inverted U shape, and the cross bar at the upper end is located above the brush 313, and the upper cross bar of the support frame 33 is provided with an arc groove 331, which is used to facilitate the placement of the gear 4, and after being placed in the arc groove 331, it will not affect the rotation of the gear 4 in the arc groove 331, and the upper cross bar of the support frame 33 is provided with a through groove 332, which is communicated with the arc groove 331, so that the teeth of the gear 4 can contact the brush 313, and after the gear 4 is placed in the arc groove 331, the brush 313 below will not lift the gear 4, thereby avoiding affecting the clamping accuracy of the gear 4.

[0032] Furthermore, after the gear 4 is placed in the arc groove 331, the gear 4 is clamped by the clamping plate 1 244 and the clamping plate 2 2452, and then the grinding wheel 28 is moved to the top of the gear 4 by the rotation of the upper screw 1 23, and then the telescopic cylinder 26 is started to drive the grinding wheel 28 to move to a position where the tooth groove of the gear 4 can be ground, and then the motor 3 27 is started to make the grinding wheel 28 grind the tooth groove, and at the same time, the grinding wheel 28 is moved horizontally in conjunction with the forward and reverse rotation of the screw 1 23 to thoroughly grind the tooth groove.

[0033] Furthermore, after the grinding of one tooth groove is completed, the motor 243 drives the rotation of the clamping plate 1 244 to rotate the gear 4 until the next tooth groove position corresponds to the grinding wheel 28. According to this processing sequence, all the tooth grooves of the gear 4 can be thoroughly ground, and during the grinding process, the brush 313 can effectively clean the ground tooth grooves.
