When installing, the positions of the bent shaft 506 and the cam disc 505 are adjusted, so that the guide wheels 517 are in contact with the alloy drill bit 519 when the guide wheels 517 are located in the grooves 515.

[0025] The gears of various specifications are realized by the following scheme: as Figure 8 、 Figure 9As shown, the flexible adjusting device includes an adjusting support 61, a scale plate 62 and a locking handle 63, the adjusting support 61 is installed on the movable frame 401 above the guide seat 502, the adjusting scale plate 62 is fixed on the side wall of the guide seat 502, a strip-shaped through groove 64 is processed on the scale plate 62, and the locking handle 63 is connected with the adjusting support 61 after passing through the strip-shaped through groove 64.

[0026] The use method of the present application is:

[0027] In the initial state, the first motor 402 controls the nut seat 405 on the lead screw 403 to be located below, then the gear to be machined is placed on the limiting pin 23 of the tray 2, at this time the main shaft 407 avoids the tray 2, leaving a gap for the work position movement of the tray 2, then the stepping motor 31 drives the dial 32 to rotate, when the dial 32 rotates, the eccentric shaft 33 cooperates with the indexing slot wheel 21 on the dial 32 to push the tray 2 to move one machining position, then the first motor 402 cooperates with the lead screw 403 and the nut seat 405 to control the main shaft 407 to move upwards, and makes the main shaft 407 to lift to the correct meshing position with the gear to be machined, to ensure the effective transmission of torque, at the same time, the asynchronous motor 518 drives the alloy drill bit 519 to rotate, and 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 through the push-pull plate 516, when the guide wheel 517 on the push-pull plate 516 falls into the groove 515, the alloy drill bit 519 enters the machining position to chamfer the gear to be machined, then the cam disc 505 pushes away the rubber wheel 508, and the guide wheel 517 leaves the groove 515, so that the gear to be machined avoids the alloy drill bit 519 to avoid tool collision; then the second motor 410 meshes with the single-tooth gear 411 and the driven gear 409, one rotation of the single-tooth gear 411 can make the driven gear 409 rotate one tooth position, the driven gear 409 synchronously drives the main shaft 407 to rotate the same angle, to realize the rotation of the gear to be machined, so as to ensure that the chamfering is evenly distributed on the entire gear edge; when the chamfering of one circle of the gear is completed, the first motor 402 drives the main shaft 407 to move downwards through the lead screw 403 and the nut seat 405, so that the key shaft 408 is separated from the machined gear, at this time the stepping motor 31 works to drive the eccentric shaft 33 on the dial 32 to push the indexing slot wheel 21 to move one machining position, and the above steps are repeated for continuous machining.

[0028] When the gear specification is replaced, for gears with small parameter gap, only the handle is pulled out, the position of the adjusting support 61 is moved according to the scale on the scale adjusting disc according to the specification of the new gear, the center distance between the alloy drill bit 519 and the chamfered gear is adjusted, the chamfer specification is changed, after adjustment, the handle is pressed to lock, and the replacement of the chamfer size is completed; for gears with large parameter gap, the single-tooth gear 411 and the driven gear 409 corresponding to the parameters also need to be replaced on the basis of the above.
