[0002] In the automobile manufacturing industry, the automobile swing arm ball hinge is an important component connecting the wheel and the vehicle body. It can effectively transmit various forces borne by the wheel to the vehicle body and ensure that the wheel can move smoothly along the predetermined trajectory. The automobile swing arm and its related components must have sufficient stiffness, strength and durability to support the vehicle body and the shock absorber, and play a role in buffering vibration when the shock absorber works, effectively assisting the operation of the lower suspension; the lower swing arm undertakes the tasks of supporting the vehicle weight and assisting steering, and is equipped with a rubber sleeve, which not only plays a fixing role, but also connects the shock absorber. The assembly quality of the swing arm ball hinge directly affects the handling performance and riding comfort of the automobile. In the assembly process of the swing arm ball hinge, the pressing of the spherical washer is a technical difficulty because it needs to be precisely installed at a specific position of the ball hinge to achieve ideal mechanical properties and durability. When using the original installation method for the spherical washer on the ball hinge, it is easy to damage the ball bowl, and it is not easy to detect the state of the ball bowl after the pressing is completed, resulting in defective products. In the new pressing method, only the ball pin itself is stressed, greatly reducing the occurrence of damage to other components. Content of the Utility Model

[0003] The utility model provides a spherical washer pressing tooling for an automobile swing arm ball hinge, which can solve the problem that the pressing of the spherical washer of the existing automobile swing arm ball hinge mostly adopts manual pressing.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0019] As Figures 1-4 shown, the present invention provides the following technical solutions to solve the problem that the pressing of the spherical washer of the existing automotive swing arm ball joint mostly uses manual pressing, which depends on the experience and skills of the operator and it is difficult to ensure the consistency of the pressing force and position: A pressing tool for the spherical washer of an automotive swing arm ball joint, including a bottom plate 8, on one side of the bottom plate 8, an aluminum plate 9 is horizontally arranged, on the upper side of the bottom plate 8, a base 7 is vertically arranged, and a plurality of positioning blocks 10 are arranged on the upper side of the aluminum plate 9; a fixed block 16, which is movably arranged up and down on the upper part of the base 7, three limiting protrusions 161 are evenly distributed on the outer side wall of the fixed block 16, and a cylindrical cushion block 5 is arranged on the upper side of the limiting protrusion 161; a cover plate 6, which is arranged on the upper side of the base 7, a nut 4 is inserted through the middle of the cover plate 6, and the corresponding fixed block 16 and nut 4 can be selected when replacing different products; a pressing head 3, which is movably arranged up and down directly above the cover plate 6, a connecting column 11 is arranged on the upper side of the pressing head 3, and an adapter plate 1 is arranged on the upper side of the connecting column 11. Through the positioning block 10 on the aluminum plate 9 and the fixed block 16 on the base 7, the precise positioning of the spherical washer can be realized to ensure its correct position in the ball hinge.

[0020] In this embodiment, as Figure 4 shown, a clamping groove 71 matching the limiting protrusion 161 is arranged at the upper end of the base 7, and an avoidance notch 72 is arranged at the lower side of the clamping groove 71 to facilitate the placement of the product.

[0021] In this embodiment, as Figure 1 shown, a mounting shaft 31 is arranged at the upper end of the pressing head 3, plug pins 2 are horizontally arranged on both sides of the mounting shaft 31, and the plug pins 2 are inserted into the connecting column 11. The pressing head 3 and the connecting column 11 can be detachably arranged through the plug pins 2.

[0022] In this embodiment, as Figure 2As shown, a pressing block 15 is provided at the lower end of the pressing head 3, and a gasket 14 is provided inside the pressing head 3 on the upper side of the pressing block 15. It is convenient for adjustment and replacement. The number and thickness of the gasket 14 can be adjusted so that the pressing position of the spherical washer can be adjusted and pressed to the required position.

[0023] In this embodiment, as Figure 1 shown, a plurality of mounting holes 91 for mounting the positioning blocks 10 are provided on the aluminum plate 9. When replacing different products, different positioning blocks 10 can be installed. The positioning blocks 10 are provided with limiting grooves for clamping the products.

[0024] In this embodiment, as Figure 3 shown, an installation groove 162 for installing the product is provided in the middle of the fixing block 16.

[0025] In this embodiment, as Figure 1 shown, place the bottom plate 8 on the workbench to ensure its stability. Install the aluminum plate 9 on one side of the bottom plate 8, and install a plurality of positioning blocks 10 on the upper side of the aluminum plate 9 to limit the position of the spherical washer. Place the fixing block 16 on the upper part of the base 7, place the cylindrical cushion block 5 on the three limiting protrusions 161, and install the cover plate 6 on the upper side of the base 7. Place the pressing head 3 directly above the cover plate 6. A connecting column 11 is connected to the upper side of the pressing head 3, and a transfer plate 1 is installed on the upper side of the connecting column 11 for connecting an external power source or a control system. First, put the spherical washer on the ball pin, and then the position of the ball pin passes through the base 7, the fixing block 16, and the cover plate 6 from bottom to top. Then, tighten the nut 4 from top to bottom. The nut 4 needs to be screwed into the threaded section of the ball pin as much as possible to ensure that the thread itself is not damaged during the pressing process. As the pressing head 3 presses down, the fixing block 16 moves down, pressing the spherical washer into the appropriate position of the ball pin. The pressing head 3 stops moving down, and the control system is turned off, and the pressing process is completed.
