Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a tool for processing a special half-axle gear shaft diameter retaining spring groove. Background Art

[0002] In the production process of special half-shaft gears, it is usually necessary to use retaining rings to fix the special half-shaft gears. In order to facilitate the installation of retaining rings, it is usually necessary to open shaft diameter retaining ring grooves. In order to facilitate the processing of shaft diameter retaining ring grooves, the staff usually use special half-shaft gear shaft diameter retaining ring groove processing tooling. The existing special half-shaft gear shaft diameter retaining ring groove processing tooling usually consists of a workbench, a fixed chuck and a milling equipment.

[0003] For example, the utility model with application number CN202121099099.7 discloses a device for processing the retaining ring groove at the end of a roller shaft. A clamping device for clamping the roller shaft and a milling device for processing the retaining ring grooves at both ends of the roller shaft are arranged on an operating table. The clamping device includes a rotatable clamping seat 1 and a clamping seat 2 which are relatively arranged. When in use, the first end of the roller shaft is clamped on the clamping seat 1, and the second end of the roller shaft is clamped on the clamping seat 2; the milling device includes a milling assembly 1 and a milling assembly 2, a milling cutter 1 of the milling assembly 1 mills a retaining ring groove 1 at the first end of the roller shaft, and a milling cutter 2 of the milling assembly 2 mills a retaining ring groove 2 at the second end of the roller shaft; the device for processing the retaining ring groove at the end of the roller shaft of the utility model adopts a one-time clamping method, and the retaining ring grooves are processed at both ends at the same time, which reduces the number of clamping times of the roller shaft and improves production efficiency. When processing the two retaining ring grooves, the same position positioning is adopted to ensure the processing accuracy of the retaining ring groove, ensure the quality of the roller shaft, and improve the service life of the roller shaft.

[0004] However, as far as the current traditional special half-shaft gear shaft diameter retaining ring groove processing tooling is concerned, during the processing, in order to prevent dust from adhering to the surface of the special half-shaft gear and affecting the processing accuracy, the staff is usually required to first clean the dust adhering to the special half-shaft gear, and then place the special half-shaft gear into a fixed chuck for fixing. The operation is relatively cumbersome and increases the labor intensity of the staff. Utility Model Content
