The utility model will be further explained with reference to the drawings.

Referring to fig. 1-4, an assembling apparatus for a rear cover bearing of a starting motor includes a vertically disposed guide post 4, a bracket 1 slidably sleeved on the guide post 4, and an elastic element for supporting the bracket 1 and providing a restoring elastic force to the bracket 1, wherein the upper end of the guide post 4 is used for supporting and positioning a bearing 3, the bracket 1 is used for supporting and positioning a rear cover 2, and a positioning position of the rear cover 2 is higher than a positioning position of the bearing 3.

In the structure, the bracket 1 can play a role of positioning the rear cover 2, the guide post 4 can play a role of positioning the bearing 3, after the rear cover 3 is pressed down by the press, the rear cover 2 is matched with the bearing 3 in a sleeved mode, the bracket 1 moves down along with the cover 2, after the press is reset, the bracket 1 resets under the action of the elastic element 6, and the assembly of the rear cover 2 and the bearing 3 is driven to lift together, so that the blanking is facilitated.

Continuing to refer to fig. 1, the upper end of the guide post 4 is provided with a positioning block 400 with a shape matched with that of the bearing 3, the cross section of the positioning block 400 is smaller than that of the guide post 4, and the bearing 3 is sleeved on the positioning block 400 and supported on the guide post 4.

With continued reference to fig. 4, the bracket 1 includes a connecting portion 100 for slidably fitting with the guide post 4 and a positioning portion 101 for supporting and positioning the rear cover 2, and the positioning portion 101 has a positioning slot 1010 corresponding to the rear cover 2. The position of the positioning part 101 is higher than that of the connecting part 100, so that the position of the rear cover 2 can be higher than that of the bearing 3.

Referring to fig. 1, the guide post 4 is provided with a limiting member, and when the bracket 1 moves up to the highest position, the bracket 1 is in blocking contact with the limiting member.

As an optimization: the limiting part is a retainer ring 5 sleeved on the guide post 4, and in addition, the limiting part can also be a stop block and other structures on the outer wall of the guide post 4.

Preferably, the elastic element is a spring 6. The spring 6 is sleeved on the guide post 4, the lower end of the guide post 4 is provided with a base 7, the lower end of the spring 6 is abutted against the base 7, and the upper end of the spring is abutted against the bracket 1.
