Gearbox differential housing processing technology

Gearbox differential housing processing technology:

1. Arrange the route of gearbox differential housing

(1) Arrange the processing process sequence first face back hole, which is because the plane area is large, the positioning is stable and reliable, which is beneficial to simplify the fixture structure and reduce the installation deformation. From the perspective of processing difficulty, the plane is easier to machine than the hole.

(2) The coarse and fine processing stages are separated. Separating the roughing and finishing is beneficial to fully expose the deformation of the workpiece after processing due to various reasons, and then eliminate it in the finishing process.

2. Selection of gearbox differential housing positioning reference

(1) The selection of the rough reference is mainly to determine the positional relationship between the machining plane and the machined surface, and to ensure that the allowance of the machined surface is uniform.

(2) The selection of the fine reference is generally “one side and two pins”, that is, positioning with the reference surface and the positioning pin hole, which is beneficial to ensure the size and position accuracy of each bearing hole, and the workpiece is easy to load and unload, reducing the auxiliary time and facilitating the improvement. productivity.
