Description

Technical Field

[0001] This utility model relates to the field of spring disassembly and assembly machine technology, specifically a car shock absorber spring disassembly and assembly machine. Background Technology

[0002] Automotive shock absorber springs are crucial components of the vehicle's suspension system, primarily used to dampen the oscillations caused by the spring's rebound after absorbing shocks and to absorb impacts from the road surface. They dissipate vibration energy through a damping effect, reducing vehicle vibration and thus improving ride comfort and vehicle stability. An automotive shock absorber spring removal and installation machine is a specialized tool used to disassemble and install automotive shock absorber springs. It is mainly used to safely compress and release the springs during shock absorber repair and replacement, avoiding injuries caused by spring force. Automotive shock absorber springs are typically under high compression; direct disassembly may cause the spring to suddenly eject, resulting in serious injury. The automotive shock absorber spring removal and installation machine ensures safe operation through mechanical fixing and compression methods.

[0003] Existing automotive shock absorber spring removal and installation machines mainly use mechanical screw compression or hydraulic compression methods. However, when fixing the spring, these machines rely solely on the operator's experience to determine whether the spring is properly secured. They lack an automatic locking function, and some machines use simple pins or manual locking devices, which cannot handle situations where the spring suddenly comes loose. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive shock absorber spring removal and installation machine to solve the problems mentioned in the background art, which rely solely on the operator's experience to judge whether the spring is fixed in place when fixing the spring, lack automatic locking function, and some equipment uses simple pins or manual locking devices, which cannot cope with the situation of the spring suddenly loosening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car shock absorber spring removal and installation machine, comprising a base and a clamping part:

[0006] The clamping part is located on the top of the base. The clamping part has a tube clamp on the top of the base. The top of the tube clamp is provided with a sleeve. A lifting frame is slidably nested on the outside of the sleeve. A slide rod is slidably provided on the side of the lifting frame. A biting chuck a is provided at one end of the slide rod. A rotating clamp is rotatably provided at the bottom of the slide rod. A sliding sleeve is slidably nested on the outside of the slide rod. The displacement of the sliding sleeve drives the rotating clamp to rotate to clamp and fix the shock absorber spring.

[0007] By adopting the above technical solution, stable clamping of the shock absorber spring can be achieved. The up-and-down movement of the sliding sleeve drives the opening and closing action of the rotating clamp, ensuring that the spring will not pop out accidentally during the disassembly and assembly process, thus improving operational safety.

[0008] Preferably, the clamping part also has a lead screw rotatably disposed inside the sleeve, and the inside of the lifting frame has a threaded groove, through which the lead screw passes vertically and is threadedly nested with the lifting frame.

[0009] By adopting the above technical solution, the lifting height of the lifting frame can be precisely controlled by rotating the lead screw, and the spring compression force can be accurately adjusted, which facilitates the disassembly and assembly of shock absorbers of different sizes.

[0010] Preferably, the clamping part also has a groove formed on the side of the lifting frame, and the slide rod passes laterally through the groove and is slidably connected to the lifting frame.

[0011] By adopting the above technical solution, the slide bar can slide smoothly in the slide groove, thereby adjusting the position of the slide bar.

[0012] Preferably, there are two slide bars, which are slidably disposed on both sides of the lifting frame and arranged in a mirror-symmetrical structure along the center of the lifting frame.

[0013] By adopting the above technical solution, bidirectional symmetrical clamping of the spring can be achieved, making the force more uniform and preventing the spring from tilting or twisting during disassembly and assembly.

[0014] Preferably, the clamping part also has a rotating shaft disposed at the bottom of the slide bar, which is embedded in one end of the rotating clamp and rotatably connected to the rotating clamp.

[0015] By adopting the above technical solution, the rotating clamp can rotate flexibly around the rotating shaft.

[0016] Preferably, the clamping part further has a biting chuck a disposed at one end of the slide bar, and a biting chuck b disposed at the end of the rotary clamp near the biting chuck a, the biting chuck b being bitingly connected to the biting chuck a.

[0017] By adopting the above technical solution, the clamping force can be enhanced by the meshing action of clamping head a and clamping head b, ensuring that the spring will not slip out under compression and improving the clamping firmness.

[0018] Preferably, the sliding sleeve is laterally nested and slides on the outside of the slide bar, and the sliding sleeve abuts against the rotating clamp.

[0019] By adopting the above technical solution, the lateral movement of the sliding sleeve can drive the closing of the rotary clamp, thereby achieving a rapid clamping operation.

[0020] Preferably, the clamping part also has a return spring nested on the outside of the slide bar, the return spring abutting against one end of the slide sleeve.

[0021] By adopting the above technical solution, the sliding sleeve can be displaced by the elastic force of the return spring after the return spring is released.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a clamping part, the shock absorber spring can be stably clamped; by moving the sliding sleeve up and down to drive the opening and closing action of the rotating clamp, the spring will not be accidentally popped out during disassembly and assembly; the mechanical linkage structure realizes the stable clamping and precise compression of the spring; the symmetrical design of the double sliding rods ensures balanced force; the adjustable lifting mechanism adapts to springs of different sizes; and the reset spring ensures operational safety.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: an automotive shock absorber spring removal and installation machine, comprising a base 1 and a clamping part 2.

[0032] The clamping part 2 is located on the top of the base 1. The clamping part 2 has a tube clamp 201 fixedly installed on the top of the base 1. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. The tube clamp 201 is used to clamp and fix the bottom of the shock absorber spring. The top of the tube clamp 201 is provided with a sleeve 202. A lifting frame 204 is slidably nested on the outside of the sleeve 202. A slide rod 207 is slidably installed on the side of the lifting frame 204. One end of the slide rod 207 is provided with a biting clamp a208. A rotating clamp 210 is rotatably installed on the bottom of the slide rod 207. A sliding sleeve 212 is slidably nested on the outside of the slide rod 207. The displacement of the sliding sleeve 212 drives the rotating clamp 210 to rotate to clamp and fix the shock absorber spring. This can achieve stable clamping of the shock absorber spring. The up and down movement of the sliding sleeve 212 drives the opening and closing action of the rotating clamp 210, ensuring that the spring will not pop out accidentally during the disassembly and assembly process, thus improving operational safety.

[0033] Example 2

[0034] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: an automotive shock absorber spring removal and installation machine, including a clamping part 2, a slide bar 207, and a clamping head b211.

[0035] A lead screw 203 is vertically rotatably installed inside the sleeve 202. A threaded groove 205 is opened inside the lifting frame 204. The lead screw 203 passes vertically through the threaded groove 205 and is threadedly nested with the lifting frame 204. The lifting height of the lifting frame 204 can be precisely controlled by rotating the lead screw 203, so as to achieve precise adjustment of the spring compression force and facilitate the disassembly and assembly of shock absorbers of different sizes.

[0036] A sliding groove 206 is provided laterally on the side of the lifting frame 204. The sliding rod 207 passes through the sliding groove 206 laterally and is slidably connected to the lifting frame 204, so that the sliding rod 207 can slide smoothly in the sliding groove 206, thereby adjusting the position of the sliding rod 207.

[0037] There are two slide rods 207. The two slide rods 207 are slidably arranged on both sides of the lifting frame 204. The two slide rods 207 are arranged in a mirror symmetrical structure along the center of the lifting frame 204, which can realize bidirectional symmetrical clamping of the spring, making the force more uniform and preventing the spring from being tilted or twisted during disassembly and assembly.

[0038] A rotating shaft 209 is integrally provided at the bottom of the slide bar 207. The rotating shaft 209 is embedded in one end of the rotating clamp 210 and is rotatably connected to the rotating clamp 210, so that the rotating clamp 210 can rotate flexibly around the rotating shaft 209.

[0039] A clamping head a208 is integrally provided at one end of the slide bar 207, and a clamping head b211 is provided at the end of the rotary clamp 210 near the clamping head a208. The clamping head b211 and the clamping head a208 are interlocked and connected. The clamping force can be enhanced by the interlocking action of the clamping head a208 and the clamping head b211, ensuring that the spring will not slip out under the compressed state and improving the clamping firmness.

[0040] The sliding sleeve 212 is laterally nested and slides on the outside of the slide rod 207, and the sliding sleeve 212 abuts against the rotating clamp 210.

[0041] By adopting the above technical solution, the lateral movement of the sliding sleeve 212 can drive the closing of the rotary clamp 210, thereby achieving a rapid clamping operation.

[0042] A return spring 213 is nested on the outside of the slide rod 207. The return spring 213 abuts against one end of the slide sleeve 212. The return spring 213 is in the open state when it is not subjected to external force. After the return spring 213 is released, the slide sleeve 212 can be displaced by the elastic force of the return spring 213. When the slide sleeve 212 is slid away from the rotating clamp 210 by external force, the slide sleeve 212 will push and squeeze the return spring 213, causing the return spring 213 to contract and store force. After the slide sleeve 212 moves away, the rotating clamp 210 will be affected by gravity and rotate open.

[0043] Working principle: First, the shock absorber assembly is placed vertically on the base 1, and the lower end of the shock absorber is fixed by the tube clamp 201. The operator rotates the screw 203, which drives the lifting frame 204 to move up and down along the sleeve 202, so that the clamping mechanism is aligned with the spring position of the shock absorber assembly. Once the lifting frame 204 reaches the appropriate height, it pushes the sliding sleeve 212 to move. When the sliding sleeve 212 slides away from the rotating clamp 210 under external force, it pushes and compresses the return spring 213, causing the return spring 213 to contract and store force. After the sliding sleeve 212 moves away, the rotating clamp 210 will rotate and open due to gravity. Then, the engaging jaws b211 and a208 move to the side of the shock absorber assembly spring. Then, the sliding sleeve 212 is released, and under the push of the return spring 213, the sliding sleeve 212 pushes the rotating clamp 210 to rotate around the rotating shaft 209, causing the engaging jaws b211 and a208 to engage and close, thus firmly clamping the spring. At this time, the two symmetrically arranged sliding rods 207 move synchronously through the sliding groove 206 to ensure that the spring is subjected to uniform force.
