[0003] The existing publication number is CN212286161U, which is a chamfering device for transmission gears of a reducer. This device realizes both front and rear adjustment and up and down adjustment of the device through the cooperation between the hydraulic telescopic rod and the fixed block, so that the staff can adjust according to the actual size of the gear when processing through the device, improving the functionality of the device, and through the matching use of the limit kit and the fastening bolt, it is convenient for the staff to fasten and limit the gears on the mounting plate to ensure the stability of the device during operation. However, this device can only perform chamfering processing on a single transmission gear when in use, and it is difficult to automatically replace a single transmission gear after chamfering, thereby reducing the chamfering efficiency of the transmission gear; and the method of fixing the transmission gear by fastening bolts is not perfect, and requires manual adjustment, which makes it easy for the transmission gear to be skewed after fixing, and affects the convenience of retracting and releasing the transmission gear before and after chamfering.
