Description

Technical Field

[0001] The utility model relates to a bearing push-out force tooling. Background Art

[0002] Currently, a push-out force test is required for bearings and bearing seats during assembly. A bearing push-out force inspection mold is required for the bearing push-out force test. However, the bearing push-out force inspection mold in the existing technology is not coaxial during the test and the force is uneven, resulting in a bearing jam problem. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides a bearing push-out force tooling.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a bearing push-out force tooling, comprising:

[0005] Lower die base;

[0006] The feature is that a core shaft extending upward is provided in the middle of the top end surface of the lower die base, a ring groove arranged around the core shaft is provided on the top end surface of the lower die base, a through hole penetrating up and down is provided inside the core shaft, and an upper die base is sleeved on the outer wall of the top end head of the core shaft.

[0007] In the above structure, a circle of annular bosses is provided on the bottom end surface of the upper die seat.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: the bearing push-out force tooling structure of the present invention is reasonably designed, and the push-out force test of the bearing is achieved through the mutual cooperation between the upper die seat and the lower die seat. It has good coaxiality and uniform force, which effectively reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Fig. 1 This is a structural schematic diagram of a bearing push-out force tooling according to an embodiment of the present utility model;

[0010] Fig. 2 This is a reference diagram of the use status of a bearing push-out force tooling described in an embodiment of the present utility model.

[0011] In the picture:

[0012] 1. Lower die base; 2. Mandrel; 3. Ring groove; 4. Through hole; 5. Upper die base; 6. Annular boss; 7. Bearing; 8. Bearing seat. DETAILED DESCRIPTION

[0013] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0014] like Figs. 1-2 As shown, a bearing push-out force tooling includes:

[0015] Lower die base 1;

[0016] It is characterized in that: a core shaft 2 extending upward is provided in the middle part of the top end surface of the lower die base 1, a ring groove 3 arranged around the core shaft 2 is provided on the top end surface of the lower die base 1, a through hole 4 penetrating up and down is provided inside the core shaft 2, and an upper die base 5 is sleeved on the outer wall of the top end head of the core shaft 2.

[0017] In the above structure, a circle of annular bosses 6 is provided on the bottom end surface of the upper die base 5 .

[0018] When the bearing push-out force tooling of the present invention is in operation, the upper die seat is connected to the tension and compression testing machine, the bearing 7 (with the bearing seat 8) after the pressure is completed is sleeved on the core shaft of the lower die seat, the top end of the core shaft is inserted into the bottom end surface of the upper die seat, the lower die seat is in contact with the table of the tension and compression testing machine, and the tension and compression test is started to complete the bearing push-out force test.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
