Description

Technical Field

[0001] This application relates to the technical field of auxiliary tools for installing automobile swing arms, and more particularly to an angle positioning tool for installing automobile swing arms. Background Art

[0002] Figure 1 As shown in the connection diagram of the automobile swing arm 6 and the vehicle frame 7, the swing arm is an important structural part in the automobile suspension system. It mainly undertakes the functions of supporting the vehicle body and the shock absorber. During the driving process of the automobile, the shock absorber will be subjected to great impact and vibration, and the automobile swing arm can play a role in buffering vibration. The shock absorber can also play a good auxiliary role in the lower suspension.

[0003] In order to ensure the working performance of the swing arm, the angle is very important during the installation and debugging of the swing arm. In the prior art, the swing arm is generally held by hand by workers and then measured with a small level. This method has a large error and the installation is relatively cumbersome.

[0004] Therefore, there is an urgent need to develop an angle positioning tool that can assist in the installation of the swing arm. Utility Model Content

[0005] The purpose of this application is to provide an angle positioning tool for installing an automobile swing arm to solve the problems raised in the above background art.

[0006] To achieve the above purpose, this application provides an angle positioning tool for installing an automobile swing arm, adopting the following technical solutions:

[0007] An angle positioning tool for installing an automobile swing arm includes a positioning rod, a gasket and a nut. The positioning rod includes a connecting section, a load-bearing section and a clearance section that are integrally bent and formed. The clearance section is U-shaped, and the end far from the connecting section is a supporting part;

[0008] A limiting block is fixed on the surface of the connecting section. The limiting block includes a limiting ring block and a hole plug that are integrally formed. The diameter of the hole plug is smaller than the diameter of the limiting ring block, and the hole plug is adapted to the shaft hole of the vehicle frame. The nut is screwed on the connecting section, and the gasket is arranged between the nut and the hole plug. The diameter of the gasket is larger than the diameter of the hole plug.

[0009] Preferably, for the convenience of the staff to operate, the nut is a hand-tightening nut.

[0010] An anti-slip sleeve is sleeved on the surface of the supporting part.

[0011] Preferably, the top edge of the hole plug is beveled. The beveled setting of the top edge of the hole plug can facilitate the staff to blindly plug the positioning tool into the shaft hole of the vehicle frame, making it more convenient to use.

[0012] In summary, the present application includes at least one of the following beneficial technical effects: The angle positioning tool for installing an automotive swing arm has a simple structure and is easy to use. The positioning rod is directly integrally bent and formed according to the assembly angle requirement. The positioning rod is cooperatively locked on the vehicle frame to directly support the swing arm and support the swing arm at a set angle, which not only improves the installation efficiency but also can ensure the installation angle of the swing arm and ensure that the swing arm has good working performance.

[0017] The following further describes the present application in detail Figures 2-3 with reference to the accompanying drawings.

[0018] An embodiment of the present application discloses an angle positioning tool for installing an automotive swing arm. Referring to Figure 2 , it includes a positioning rod 1, a gasket 2 and a nut 3. The positioning rod 1 includes a connecting section 11, a load-bearing section 12 and a clearance section 13 that are integrally bent and formed. The clearance section 13 is U-shaped, and one end away from the connecting section 11 is a support portion. An anti-slip sleeve 14 is sleeved on the surface of the support portion;

[0019] A limiting block is fixed on the surface of the connecting section 11. The limiting block includes a limiting ring block 4 and a hole plug 5 that are integrally formed. The diameter of the hole plug 5 is smaller than the diameter of the limiting ring block 4, and the hole plug 5 is adapted to the shaft hole of the vehicle frame. The nut 3 is screwed on the connecting section 11. The gasket 2 is arranged between the nut 3 and the hole plug 5. The diameter of the gasket 2 is larger than the diameter of the hole plug 5. For more convenient use, the nut 3 is a hand-tightening nut 3, and the staff can easily turn the hand-tightening nut 3, which is efficient and convenient.

[0020] Referring to Figure 2 , the top edge of the hole plug 5 is provided with an oblique angle. The oblique angle setting of the top edge of the hole plug 5 can facilitate the staff to blindly plug the positioning tool into the shaft hole of the vehicle frame, and the use is relatively convenient.

[0021] The implementation principle of an angle positioning tool for installing an automotive swing arm in an embodiment of the present application is as follows:

[0022] Reference Figure 2 and Figure 3 , the staff first connects the swing arm to the vehicle frame through a pin shaft, then inserts the positioning rod 1 into the shaft hole of the vehicle frame from below upwards, and presses the supporting part against the designated contact point of the swing arm. Then, the positioning rod 1 can be fixed by the gasket 2 and the hand-tightening nut 3. The angle of the supporting part in the positioning rod 1 is set, so that the positioning rod 1 can directly support the swing arm at the most suitable angle. The positioning rod 1 can directly liberate the hands of the staff and greatly improve the assembly efficiency.

[0023] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
