The eccentric shaft 33 is parallel to the output shaft of the stepping motor 31. A plurality of bearings 34 that can be inserted into the indexing groove wheel 21 are mounted on the eccentric shaft 33. The bearings 34 are used to reduce the friction between the eccentric shaft 33 and the indexing groove wheel 21. The eccentric shaft 33 rotates one circle with the dial 32 to drive the indexing groove wheel 21 to rotate The gear 22 on the tray 2 is rotated by one indexing position, and the avoidance groove 22 on the tray 2 is rotated by one processing position. The figure shows a four-slot indexing groove wheel 21, that is, the dial 32 rotates one circle, and the eccentric shaft 33 on the dial 32 drives the avoidance groove 22 on the tray 2 to rotate 90°.

The gear rotating device 4 is installed below the tray 2, and the grinding device 5 is installed on the frame 1 above one side of the tray 2. The gear rotating device 4 is used to lift the gear to be processed from the tray 2 and drive The gear rotates to facilitate the chamfering process by the grinding device 5.

The CNC module 7 is an existing servo system, which mainly controls the operation of the driving mechanism 3, the gear rotating device 4 and the grinding device 5. The control method is a mature existing technology, so it will not be repeated here.

[0024] The chamfering mechanism is realized by the following scheme: Figures 4 to 7As shown, the gear rotating device 4 includes a movable frame 401, a first motor 402, a screw rod 403, a nut seat 405, a slide rail 404, a sliding bracket 406, a main shaft 407, a key shaft 408, a driven gear 409, a second motor 410 and a single-tooth gear 411. The movable frame 401 can be horizontally movably installed in the frame 1. The first motor 402 is fixed on the movable frame 401. A vertically arranged screw rod 403 is installed on the output shaft of the first motor 402. The slide rail 404 is vertically installed on the movable frame 401 on one side of the screw rod 403. The sliding bracket 406 is slidably installed on the slide rail 404 and can slide up and down along the slide rail 404. The nut seat 405 is installed on the sliding bracket, and the nut seat 405 is threadedly connected to the screw rod 403. The main shaft 407 is vertically rotatably installed on the sliding bracket 406 through a bearing seat 34. A key shaft 408 matching the size of the gear to be processed is detachably installed on the top of 07, and the first motor 402 drives the nut seat 405 to rise and fall through the screw rod 403. When the nut seat 405 rises and falls, it drives the sliding bracket to move up and down along the slide rail 404, and the sliding bracket drives the key shaft 408 on the main shaft 407 to lift the gear to be processed from the processing position to wait for chamfering. The driven gear 409 is installed at the lower part of the main shaft 407, and the second motor 410 is installed on the movable frame 401 on one side of the driven gear 409. A single-tooth gear 411 is installed on the output shaft of the second motor 410. When the main shaft 407 moves to the upper limit position, the single-tooth gear 411 and the driven gear 409 are in the same horizontal plane, and the second motor 410 drives the single-tooth gear 411 to rotate one circle, and the single-tooth gear 411 drives the driven gear 409 to rotate one tooth position, so that the grinding device 5 gradually chamfers the gear to be processed;The grinding device 5 includes a guide plate 501, a guide seat 502, a polished rod 503, a cam motor 504, a cam plate 505, a crank shaft 506, a rubber wheel 508, a push rod 507, a push frame 509, a track 510, a slider 511, a connecting rod 512, a guide groove plate 514, a push-pull plate 516, an asynchronous motor 518 and an alloy drill bit 519. The guide plate 501 is fixedly mounted on the frame 1, the guide seat 502 is fixedly connected to the movable frame 401, two horizontally arranged polished rods 503 are installed on the guide seat 502, and both ends of the polished rods 503 are installed on the frame 1 on one side of the guide plate 501. A cam motor 504 is installed, and a cam plate 505 and a crank shaft 506 are installed on the output shaft of the cam motor 504 in sequence from bottom to top. A push rod 507 is installed on the side wall of the guide seat 502 close to the guide plate 501 and is in the same horizontal plane as the cam plate 505. A rubber wheel 508 that can rotate freely and abuts against the side wall of the cam plate 505 is installed at the end of the push rod 507. The cam plate 505 and the rubber wheel 508 are in rolling cooperation, which can drive the gear rotating device 4 to approach or move away from the grinding device 5. After the grinding device 5 completes a single grinding, the cam plate 505 pushes the guide seat 502 away to prevent the grinding device 5 from hitting the gear to be processed. In order to ensure reset, the guide A compression spring is mounted on the light rod 503 on the side of the seat 502 away from the guide plate 501; the push frame 509 is installed on the frame 1 on the other side of the guide plate 501 through a track 510, and the push frame 509 is installed with a slider 511, and the two ends of the connecting rod 512 are respectively connected to the crank shaft 506 and the slider 511 through a connecting sleeve 513, and the crank shaft 506 can drive the push frame 509 to reciprocate along the track 510, and the guide groove plate 514 is installed on the frame 1 above the guide plate 501, and the surface of the guide groove plate 514 is processed with a groove 515 aligned with the processing position, and the push-pull plate 516 is placed above the guide groove plate 514, and the bottom of the push-pull plate 516 A guide wheel 517 corresponding to the groove 515 is installed on the surface. One side of the push-pull plate 516 is hinged with the push frame 509 through a pull rod 520. The push frame 509 drives the push-pull plate 516 to make the guide wheel 517 roll back and forth in the groove 515 on the guide groove plate 514. The asynchronous motor 518 is installed on the push-pull plate 516. The alloy drill bit 519 is connected to the output shaft of the asynchronous motor 518. The alloy drill bit 519 chamfers the gear to be processed when the guide wheel 517 enters the groove 515 through the asynchronous motor 518. When the guide wheel 517 leaves the groove 515, the alloy drill bit 519 is located above the gear to be processed to avoid the gear from hitting the cutter. During installation, the position of the crank shaft 506 and the cam plate 505 should be adjusted so that when the guide wheel 517 is located in the groove 515, the gear to be processed contacts the alloy drill bit 519. ;

[0025] Adapting to various specifications of gears is achieved through the following solutions: Figure 8 , Fig. 9As shown, the flexible adjustment device includes an adjustment bracket 61, a scale plate 62 and a locking handle 63. The adjustment bracket 61 is installed on the movable frame 401 above the guide seat 502, and the adjustment scale plate 62 is fixed on the side wall of the guide seat 502. A strip through groove 64 is processed on the scale plate 62. The locking handle 63 passes through the strip through groove 64 and is connected to the adjustment bracket 61. Since gears of different specifications have different modules, numbers of teeth, pitch circle diameter and other parameters, the relative position of the guide seat 502 and the movable frame 401 can be adjusted by adjusting the position of the locking handle 63 on the adjustment bracket 61. At the same time, the corresponding single-tooth gear 411 and the driven gear 409 are selected to adjust the spacing between the gear rotating device 4 and the grinding device 5. When adjusting the spacing between the alloy drill bit 519 and the gear to be processed, the locking handle 63 is pulled open and released, and then moved to the corresponding position on the scale plate 62, and then tightened to complete the adjustment.

[0026] The method of using the present invention is:

[0027] When in the initial state, the first motor 402 controls the nut seat 405 on the screw rod 403 to be located at the bottom, and then the gear to be processed is placed on the limit pin 23 of the tray 2. At this time, the main shaft 407 avoids the tray 2, leaving a gap for the station movement of the tray 2, and then the stepping motor 31 drives the dial 32 to rotate. When the dial 32 rotates, the eccentric shaft 33 cooperates with the upper indexing groove wheel 21 to push the tray 2 to move a processing position. Then the first motor 402 cooperates with the nut seat 405 through the screw rod 403 to control the main shaft 407 to move upward, and make the main shaft 407 rise and fall to the correct meshing position with the gear to be processed to ensure the effective transmission of torque. At the same time, the asynchronous motor 518 drives the alloy drill bit 519 to rotate, and at the same time, the driving force of the cam motor 504 is transmitted to the push frame 509 through the connecting rod 512. The push frame 509 drives the asynchronous motor 518 to reciprocate on the guide groove plate seat through the push-pull plate 516, and the guide wheel 517 on the push-pull plate 516 When falling into the groove 515, the alloy drill bit 519 enters the processing position to chamfer the gear to be processed, and then the cam plate 505 pushes the rubber wheel 508 away, and the guide wheel 517 leaves the groove 515, so that the gear to be processed avoids the alloy drill bit 519 to avoid collision with the tool; then the second motor 410 engages with the driven gear 409 through the single-tooth gear 411, and the single-tooth gear 411 rotates one circle to make the driven gear 409 rotate one tooth position, and the driven gear 409 synchronously drives the main shaft 407 to rotate the same angle to achieve the self-rotation of the gear to be processed, which can ensure that the chamfering process evenly covers the entire gear edge; when the gear is chamfered in one circle, the first motor 402 drives the main shaft 407 to move downward through the screw rod 403 and the nut seat 405, so that the key shaft 408 is separated from the processed gear, and at this time the stepping motor 31 works, driving the eccentric shaft 33 on the dial 32 to push the indexing groove wheel 21 to move one processing position, and repeat the above steps for continuous processing.

[0028] When replacing gear specifications, for gears with smaller parameter differences, it is only necessary to pull out the handle, and according to the specifications of the new gear, move the position of the adjustment bracket 61 according to the scale on the scale adjustment dial to adjust the center distance between the alloy drill bit 519 and the chamfered gear to achieve the change of chamfering specifications. After adjustment, press the handle to lock it, and the chamfering size can be replaced; for gears with larger parameter differences, it is necessary to replace the single-tooth gear 411 and the driven gear 409 with corresponding parameters on the basis of the above.

[0029] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitation of the present invention.
