Description

Technical Field

[0001] This utility model relates to a positioning device, specifically a positioning device for gear chamfering, belonging to the field of gear chamfering technology. Background Technology

[0002] Chamfering refers to the machining process of cutting the edges of a workpiece into a certain bevel. Gear chamfering is the machining process of chamfering the corners of the end face and tooth surface of the gear, that is, the tooth profile edge. In order to prevent the sharp corners of the gear from chipping during meshing, the sharp corners need to be chamfered after the gear is machined.

[0003] Chinese patent application publication number CN219074586U discloses a chamfering device for one-way gears. This invention adjusts the contact point between the chamfering cutter and the gear via an adjustment drive unit during the chamfering process. This allows for the continuous chamfering of a single gear using a single chamfering cutter while minimizing overheating and wear, thus shortening the chamfering time and improving efficiency.

[0004] Although the above-mentioned patent solution can perform chamfering on gears, the gear chamfering processing device in the above-mentioned patent is not convenient for positioning gears of different sizes or modules. The gear is fixed by using a positioning seat groove. When processing gears of different modules, it is necessary to replace the groove inside the corresponding positioning seat, which makes the gear positioning process cumbersome.

[0005] Therefore, a positioning device for gear chamfering is proposed here. Utility Model Content
