[0049] The working principle of a universal gear rack tooth profile processing device disclosed in the present invention is as follows: by loosening the clamping button 113, the position of the adjusting frame 110 and the connecting frame 109 can be manually adjusted, and the adjusting frame 110 can be pressed against the connecting frame 109 by the clamping button 113, so that the position of the adjusting frame 110 and the connecting frame 109 is fixed, and the sliding motor 106 drives the motor gear 107 to rotate, so that the motor gear 107 cooperates with the fixed rack 103 to realize the sliding of the slider 105 along the bottom frame 102 and the guide column 104, thereby adjusting the position of the rack 230 to be processed and the gear 326 to be processed. Before processing, the inner push handle 218 can be pressed to drive the snap-in column 221 to slide outward, so that the snap-in column 221 leaves the adjustment hole 231, the inner push spring 219 is compressed, and the snap-in spring 222 is compressed. At this time, the angle between the clamping seat 216 and the lifting plate 210 can be adjusted, and then the inner push handle 218 is released, the inner push spring 219 and the snap-in spring 222 rebound, so that the snap-in column 221 is inserted into the specified adjustment hole 231, completing the angle adjustment between the clamping seat 216 and the lifting plate 210, thereby adjusting the tooth angle of the rack 230 to be processed; by pulling out the pull-out handle 212, the pull-out spring 215 is stretched, so that the inner tooth block 213 is disengaged from the vertical screw rod 203, and the height of the lifting rod 209 and the lifting plate 210 can be quickly adjusted at this time to determine the initial processing position; by adjusting the position of the ratchet frame 205, the position of the ratchet bar 206 can be adjusted, thereby adjusting the time for each engagement of the bottom ratchet 204 and the ratchet bar 206, thereby adjusting the distance that the clamping seat 216 is lifted and lowered each time during processing. By adjusting the position of the vertical rack frame 303, the time of each engagement of the lower ratchet 308 and the side ratchet bar 304 can be adjusted, thereby adjusting the angle of rotation of the gear 326 to be processed each time the reciprocating slide 302 reciprocates; manually driving the adjusting worm 311 to rotate, thereby driving the adjusting turbine 312 and the rotating seat 310 to rotate, thereby adjusting the processing angle of the teeth of the gear 326 to be processed.

[0050] The rack 230 to be processed is placed between the two clamping plates 229 by hand, and the clamping motor 223 drives the motor bevel gear 224 to rotate, thereby driving the screw bevel gear 226 and the clamping screw 225 to rotate, thereby driving the two clamping blocks 228 and the clamping plate 229 to slide inward along the clamping guide column 227 at the same time, and the rack 230 to be processed is clamped by the clamping plate 229. In the process of the cutting gear 112 cutting the teeth of the rack 230 to be processed, the linear motor stator 108 drives the rack end mover 201 and the reciprocating sliding seat 202 to slide back and forth, cooperating with the cutting gear 112 to cut teeth. When the rack end mover 201 moves left During the movement, the bottom ratchet 204 contacts the ratchet bar 206. At this time, the ratchet bar 206 will not drive the bottom ratchet 204 to rotate, the cross column spring 208 will be compressed, the cross column 207 and the ratchet bar 206 will slide outward, and when the rack end mover 201 moves to the right, the ratchet bar 206 drives the bottom ratchet 204 and the vertical screw rod 203 to rotate, thereby driving the lifting rod 209 and the lifting plate 210 to descend once through the thread cooperation of the internal tooth block 213 and the vertical screw rod 203, thereby driving the rack 230 to be processed to descend once, each time it descends one tooth distance, thereby realizing the overall processing of the rack 230 to be processed in this reciprocating manner. The gear 326 to be processed is placed on the outside of the three expansion plates 325, and the adjusting wheel 321 and the threaded column 322 are manually driven to rotate, which can drive the internal threaded sleeve 323 to slide along the inner rotating cylinder 320, thereby driving the expansion connecting rod 324 to rotate, thereby driving the expansion plate 325 to move outward, and the gear 326 to be processed is fixed by the expansion plate 325. The linear motor stator 108 drives the gear end mover 301 and the reciprocating slide 302 to slide back and forth. When the reciprocating slide 302 moves to the right, the lower ratchet 308 contacts the side ratchet bar 304, and the side ratchet bar 304 will not drive the lower ratchet 308 to rotate. The rack spring 306 will be compressed, and the side ratchet bar 304 and rack slide 305 will slide downward. When the reciprocating slide 302 moves to the left, the lower ratchet 308 contacts the side ratchet bar 304, and the side ratchet bar 304 drives the lower ratchet 308 and the lower rotating wheel 307 to rotate. The transmission belt 309 drives the inner gear ring 313 to rotate, driving the docking gear 316, the gear shaft 315 and the docking bevel gear 317 to rotate, thereby driving the rotating bevel gear 319 and the inner rotating cylinder 320 to rotate. The expansion plate 325 drives the gear to be processed 326 to rotate one tooth angle each time, thus reciprocating to achieve the gear cutting process of the gear to be processed 326. The cutting motor 111 rotates and drives the cutting gear 112 to rotate, and the cutting gear 112 cuts the teeth of the rack 230 to be processed and the gear to be processed 326.
