Description

Technical Field

The above document still has shortcomings. When used, it solves the technical problem that the gears with large outer circles, thin wheels, and weight-reducing holes on the spokes have large tooth deformation after heat treatment, which causes the workpiece teeth to be scrapped because they cannot be ground. The utilization rate of raw materials is improved, thereby reducing the processing cost of gears. However, the distance between the positioning mechanisms on both sides is fixed in the above-mentioned middle. When used, only gears of fixed size to be processed can be positioned, which is not convenient for positioning gears of different sizes to be processed, thereby reducing the performance of the shaping device. At the same time, when shaping the gear to be processed in the above document, the gear to be processed needs to be re-clamped to realize the rotation of the gear to be processed to shape the different positions of the gear to be processed, which is more troublesome to operate. When shaping the gear to be processed, it is not convenient to rotate the gear to be processed. Utility Model Content
