Description

Technical Field

[0001] The utility model relates to the technical field of sprocket processing, in particular to a non-standard sprocket deburring device. Background Art

[0002] Crankshaft sprockets are widely used in the field of automobile engines. The sprocket at the rear end of the crankshaft is used for chain transmission. Sprockets are usually processed and manufactured by methods such as gear shaping and gear hobbing.

[0003] Publication No. CN219633345U discloses a deburring machine for sprocket processing. The patent places the sprocket on a non-slip pad on a rotating seat, drives a motor, and the motor drives the shaft to rotate. The shaft causes the rotating seat to rotate, and then the sprocket is rotated through the non-slip pad. When the next notch of the sprocket faces the grinding block, the driving motor is stopped, and then the above grinding steps are performed to complete the sprocket rotation deburring process, so that the sprocket can be rotated for deburring. When it is necessary to grind other teeth of the sprocket, manual adjustment of the position of the sprocket is avoided. However, the patent still has the following problems in actual use:

[0004] The motor drives the shaft to rotate, and the shaft causes the rotating seat to rotate accordingly, and then the sprocket is rotated through the anti-skid pad. When the next notch of the sprocket faces the grinding block, the driving motor is stopped, and then the above grinding steps are performed to complete the sprocket rotation deburring process. However, when deburring the sprocket in actual use, it must be ensured that the sprocket is located at the center of the rotating seat. If the sprocket is placed, it is not positioned, so that if the sprocket rotates during the processing, it is possible to rotate offset, which will affect the quality of the sprocket deburring process.

[0005] A non-standard sprocket deburring device is proposed to solve the above-mentioned problems. Utility Model Content
