[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] Example

[0017] In order to solve the above technical problems, this embodiment provides a rotating shaft assembly and a retaining spring assembly device, such as Figure 1-2 As shown, it includes a base 10, a positioning component 20 coaxially arranged on the base 10, and a clamping component 30 for clamping the rotating shaft component. The positioning component 20 is used to position the retaining spring. A driving component 40 is connected to the end of the clamping component 30 away from the positioning component 20. The driving component 40 is used to drive the clamping component 30 to approach or move away from the positioning component 20, so that the retaining spring on the positioning component 20 is installed into the end of the rotating shaft component. The rotating shaft component is clamped by the clamping component 30, and then the end of the rotating shaft component is driven to move toward the positioning component 20 by the driving component 40. The rotating shaft component is driven by the driving component 40 to squeeze the positioning component 20, so that the retaining spring on the positioning component 20 is sleeved on the end of the rotating shaft component, thereby realizing semi-automatic installation of the retaining spring and improving the insertion efficiency and installation accuracy.

[0018] In order to avoid deviation in the installation of the retaining spring, as a preferred embodiment, the clamping assembly 30 includes a first mounting seat 31 for clamping the rotating shaft assembly and guide blocks 32 slidably fitted on both sides of the first mounting seat 31. The driving end of the driving assembly 40 is connected to the first mounting seat 31, and the first mounting seat 31 can slide along the guide blocks 32 to approach or move away from the positioning assembly 20. By setting the guide blocks 32, when the driving assembly 40 drives the first mounting seat 31 to approach the positioning assembly 20, the guide blocks 32 on both sides of the first mounting seat 31 guide the movement of the first mounting seat 31, thereby avoiding the first mounting seat 31 from tilting during the movement, which causes deviation in the installation of the retaining spring, and realizing the guided movement of the clamping assembly to cooperate with the installation of the retaining spring.

[0019] As a preferred embodiment, the base 10 is provided with a slide groove 11 along the direction of the guide block 32, and the first mounting seat 32 is slidably set in the slide groove 11. By setting the slide groove 11, when the driving component 40 drives the first mounting seat 31 to approach the positioning component 20, the slide groove 11 at the bottom of the first mounting seat 31 guides the movement of the first mounting seat 31, thereby preventing the first mounting seat 31 from tilting during the movement, causing deviation in the installation of the retaining spring, and realizing the clamping component approaching or moving away from the positioning component to cooperate with the installation of the retaining spring.

[0020] In order to expand the inner hole of the retaining spring to achieve positioning installation, as a preferred embodiment, the positioning component 20 includes a second mounting seat 21, and the second mounting seat 21 is movably penetrated with a positioning shaft 22 for positioning the retaining spring. The side of the positioning shaft 22 away from the clamping component 30 is installed with an elastic member 23. By installing the retaining spring on the positioning shaft 22, and then driving the rotating shaft component close to the positioning shaft 22 on the positioning component 20 through the driving component 40, while the rotating shaft component squeezes the positioning shaft 22, the retaining spring installed on the positioning shaft 22 expands the inner hole through the guide bevel 222, completing the positioning installation of the retaining spring. When the rotating shaft assembly is away from the positioning shaft 22, the positioning shaft 22 is reset by the elastic reset of the elastic member 23. By setting the positioning shaft 22, the inner hole of the retaining spring is enlarged. Then, when the end of the rotating shaft assembly pushes the positioning shaft 22 into the second mounting seat 21, the retaining spring on the positioning shaft 22 is sleeved on the end of the rotating shaft assembly. When the rotating shaft assembly is away from the positioning shaft 22, the positioning shaft 22 is reset by the elastic reset of the elastic member 23. By setting a telescopically movable positioning shaft 22 on the second mounting seat 21, the inner hole of the retaining spring is enlarged to cooperate with the positioning and mounting retaining spring.

[0021] As a preferred embodiment, the positioning assembly 20 also includes a third mounting seat 24 arranged on the side of the second mounting seat 21 away from the clamping assembly 30. One end of the elastic member 23 abuts against the positioning shaft 22, and the other end abuts against the third mounting seat 24. When the rotating shaft assembly is away from the positioning shaft 22, the elastic reset of the elastic member 23 drives the positioning shaft 22 to reset, thereby realizing the positioning shaft installation reset.

[0022] As a preferred embodiment, a positioning boss 221 is provided at the end of the positioning shaft 22 close to the clamping assembly 30, and a guide bevel 222 is formed on the side of the positioning boss 221 away from the clamping assembly 30. The retaining spring is placed between the positioning boss 221 and the second mounting seat 21. The retaining spring is installed on the positioning shaft 22, and the driving assembly 40 drives the rotating shaft assembly to push the positioning shaft 22 on the positioning assembly 20. While the rotating shaft assembly pushes the positioning shaft 22, the retaining spring installed on the positioning shaft 22 expands the inner hole through the guide bevel 222. When the positioning boss 221 of the positioning shaft 22 is pushed into the second mounting seat 21, the retaining spring is folded and sleeved on the end of the rotating shaft assembly to complete the positioning and installation of the retaining spring. By setting the guide bevel 222, the inner hole of the retaining spring is expanded to cooperate with the installation of the retaining spring.
