Description
Technical Field
[0001] This utility model relates to the field of automotive repair technology, specifically to a disassembly tool for an automotive shock absorber and an automotive. Background Technology
[0002] During driving, cars are subjected to various impacts and vibrations from the road surface. As a key component of the car's suspension system, the shock absorber effectively buffers these impacts, improving driving stability and comfort. Typically, a shock absorber consists of a damping assembly and a coil spring, forming a MacPherson strut or other types of suspension structure. The coil spring is generally under compression on the damping assembly, storing a large amount of elastic potential energy.
[0003] When repairing shock absorbers, they need to be removed from the vehicle and the shock absorber assembly separated from the coil spring. However, because the coil spring is under high preload, forcibly removing it without effectively limiting its deformation may cause it to pop out instantly, resulting in personal injury or equipment damage. Therefore, specialized automotive shock absorber removal tools are usually used to clamp the coil spring, fixing its shape and preventing it from popping out instantly.
[0004] While existing automotive shock absorber disassembly fixtures are simple in structure, they require additional tools such as screwdrivers to fix the coil spring shape, making it inconvenient for repair personnel to operate by hand. Utility Model Content

[0029] Implementation Method 1
[0030] like Figures 1 to 4 As shown, this utility model provides a disassembly fixture for an automotive shock absorber. The automotive shock absorber includes a shock-absorbing assembly and a coil spring. The disassembly fixture is used to fix the shape of the coil spring. It includes: a bracket 1, a position adjustment unit 2, a first clamping unit 3, and a second clamping unit 4. The position adjustment unit 2 is disposed on the bracket 1 and is used to drive the first clamping unit 3 to move along the height direction H of the bracket 1 to adjust the position of the first clamping unit 3. The first clamping unit 3 is connected to the position adjustment unit 2. The first clamping unit 3 and the second clamping unit 4 are arranged along the height direction H of the bracket 1, and there is a placement space between the first clamping unit 3 and the second clamping unit 4 for placing the automotive shock absorber. When the automotive shock absorber is placed in the placement space along the height direction H of the bracket 1, the coil spring is clamped between the first clamping unit 3 and the second clamping unit 4 to maintain its shape.
[0031] In practical implementation, a bracket 1 provides an overall support structure; a position adjustment unit 2 is mounted on the bracket 1 and is used to drive the first clamping unit 3 to move along the height direction H of the bracket 1, thereby adapting to coil springs of different heights and sizes; the first clamping unit 3 is connected to the position adjustment unit 2 and can move with it, cooperating with the second clamping unit 4 to clamp the coil spring; the second clamping unit 4 and the first clamping unit 3 are arranged along the height direction H, forming a placement space for placing the car shock absorber; when the car shock absorber is placed in this placement space along the height direction H, the coil spring is clamped between the first clamping unit 3 and the second clamping unit 4, thereby maintaining its shape and preventing pop-out accidents due to the release of elastic potential energy. Through the coordinated action of the adjustable first clamping unit 3 and the second clamping unit 4, the coil spring can be stably clamped without the need for additional tools such as screwdrivers, improving operational convenience and safety, and solving the technical problem in the prior art that disassembling the fixture requires the use of auxiliary tools such as screwdrivers to fix the shape of the coil spring.
[0032] According to one embodiment of the present invention, the bracket 1 includes a first support mechanism 11, a second support mechanism 12, and a third support mechanism 13; the second support mechanism 12 is located between the first support mechanism 11 and the third support mechanism 13, and the first support mechanism 11 is connected to the third support mechanism 13 through the second support mechanism 12; the position adjustment unit 2 is disposed on the third support mechanism 13; the first clamping unit 3 and the second clamping unit 4 are located between the first support mechanism 11 and the third support mechanism 13.
[0033] In this embodiment, the first support mechanism 11 and the third support mechanism 13 can be in a horizontal state, and the second support mechanism 12 can be in a vertical state.
[0034] According to one embodiment of the present invention, the position adjustment unit 2 includes a linear motion mechanism.

[0036] In practical implementation, when the lead screw 22 is rotated, the nut 23 moves along the axial direction of the lead screw 22, driving the first clamping unit 3 to move along the height direction H of the bracket 1. This structure achieves precise position adjustment of the first clamping unit 3 through the cooperation of the lead screw 22 and the nut 23, improving operational convenience and enhancing adaptability to helical springs of different specifications.
[0037] According to one embodiment of the present invention, the linear motion mechanism further includes a connecting sleeve 24 and at least one control lever 25; the lead screw 22 passes through the connecting sleeve 24 and is inserted into the bearing 21; the control lever 25 is disposed on the connecting sleeve 24 and is arranged at an angle to the lead screw 22.
[0038] In practice, the control lever 25 is mounted on the connecting sleeve 24 and is set at a certain angle to the lead screw 22. This design allows the operator to indirectly drive the lead screw 22 to rotate by rotating the control lever 25, thereby adjusting the position of the lead nut 23 and realizing the height adjustment of the first clamping unit 3. The control lever 25 provides a better operating lever arm, making the rotation control of the lead screw 22 more convenient and labor-saving, and improving the operational convenience and work efficiency of the entire disassembly fixture.

[0043] In practical implementation, with the above-mentioned structural settings, in addition to adjusting the position of the first clamping unit 3 in the height direction H of the bracket 1 through the position adjustment unit 2, it can also be adjusted through the fastener 7, that is, the fastener is inserted into different position adjustment holes 61 to improve the flexibility of the tooling.

[0045] In practice, the fastening nut 8 is positioned below the second clamping unit 4, engaging with the threaded section of the limiting rod 5 and abutting against the lower end face of the second clamping unit 4. This serves to restrict the movement of the second clamping unit 4 toward the first support mechanism 11 when tightened. This structure, through the engagement of the fastening nut 8 and the threaded section, locks the position of the second clamping unit 4, preventing displacement during operation. This further enhances clamping stability and safety, and allows the fixture to more reliably adapt to helical springs of different heights, improving overall ease of use and applicability.
