The fixture can be further subdivided into process assembly fixtures, project test fixtures and circuit board test fixtures, etc. The bearing of the gear box cover is a pinion shaft installed in the gear box body through the bearing and the bearing cover, and the pinion meshes with the large gear to transmit power.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing press-fitting jig is used to press-fit the bearing of the gear box cover, the staff is required to manually position the bearing of the gear box cover and then push it for press-fitting. The operation process is relatively cumbersome, which affects work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a bearing press-fitting jig for a gear box cover, so as to solve the problem that when the existing press-fitting jig is used to press-fit the bearing of the gear box cover, the staff needs to manually position the bearing of the gear box cover and then push it for press-fitting, which results in a cumbersome operation process and affects work efficiency.
