Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber installation equipment, in particular to a spring fixing tool for shock absorber assembly. Background Art

[0002] Shock absorber is mainly used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] When assembling the shock absorber, the spring needs to be compressed and installed. The assembly process of the shock absorber is as follows: place the spring on the spring disk of the damper; place the damper with the spring into the machine for positioning; compress the spring; assemble the dust cover and install the support; tighten the nut; and finally cut the material.

[0004] Before compressing the spring, the top of the spring needs to be limited to ensure successful compression. In the prior art, most of them limit the upward movement of the top of the spring by setting an annular plate at the top of the spring. Since the top of the spring is not a plane, when the annular plate limits the top of the spring, it is easy to cause the spring to be misaligned, resulting in the need to adjust the shock absorber after installation, which is very inconvenient.

[0005] In view of this, there is an urgent need for a spring fixing tool for assembling a shock absorber. Summary of the invention

[0006] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A spring fixing tool for shock absorber assembly, comprising a mounting frame and a plurality of limiting rods, wherein the mounting frame is arranged to form a spring assembly space;

[0009] The limiting rod is rotatably arranged on the mounting frame, the rotation direction of the limiting rod relative to the mounting frame is horizontal, the suspension end of the limiting rod is the spring fixing end, and a plurality of the limiting rods are arranged along the annular direction of the spring assembly space.

[0010] A further feature is that

[0011] The spring fixing end is provided with a groove.

[0012] The mounting frame comprises two mounting plates arranged in parallel from bottom to top, a plurality of mounting rods are vertically arranged between the two mounting plates, and a plurality of limiting rods are respectively arranged on corresponding mounting rods.

[0013] A collar is sleeved on the mounting rod, and the limiting rod is arranged on the collar.

[0014] A mounting ring is arranged on the ring side of the sleeve ring. The mounting ring extends in a horizontal direction. One end of the limiting rod is passed through the mounting ring.

[0015] The mounting plate is C-shaped.

[0016] The mounting frame also includes a plurality of connecting rods arranged between the two mounting plates.

[0017] The number of the limiting rods is three.

[0018] The three limiting rods are evenly distributed around the circumference.

[0019] The mounting rod is provided with a scale.

[0020] The above structure of the utility model can achieve the following beneficial effects:

[0021] During assembly, when it is necessary to fix the top of the spring, several limiting rods are rotated to rotate the fixed end of the spring to the top of the spring. Multiple spring fixed ends are placed at different positions of the top of the spring to limit the upward movement of the spring, thereby completing the fixation of the top of the spring. Several limiting rods can move independently to ensure that the spring remains in a straight position during the compression process, thereby reducing the need to adjust the spring after the shock absorber is assembled.
