Description

Technical Field

[0001] The utility model specifically relates to the technical field of gear processing and positioning, in particular to a positioning tool for gear end surface processing. Background Art

[0002] Gears are mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear generation and special machine tools and tools that use this principle to generate gears appeared one after another. With the development of production, the stability of gear operation has received attention.

[0003] Gears can be divided into gear teeth, tooth grooves, end faces, normal faces, tooth top circles, tooth root circles, base circles, pitch circles and other parts according to their structures. The current processing flow of gears is forging, normalizing, turning, gear hobbing and gear shaping, gear shaving, heat treatment and grinding. Specifically, grinding is the finishing of the inner hole, end face, outer diameter of the shaft and other parts of the gear after heat treatment to improve dimensional accuracy and reduce geometric tolerances.

[0004] However, when the existing clamp clamps the gear, the gear teeth on the gear are squeezed through the clamping plate, and the contact area between the gear and the clamping plate is limited. When the clamping force is too large, the local pressure on the gear teeth is relatively large, and the gear teeth are easily squeezed excessively, deformed and damaged. When the clamping force is small, the fixing effect of the clamp on the gear cannot be guaranteed. Therefore, there is a need to further improve the gear fixing clamp. Utility Model Content
