Description

Technical Field

[0001] This utility model relates to a disassembly device for a hydraulic vibration damper. It belongs to the technical field of hydraulic vibration dampers. Background Technology

[0002] Hydraulic shock absorbers are widely used in automotive suspension systems to reduce vehicle vibration and bumps, improving ride comfort and stability.

[0003] Currently, hydraulic shock absorbers are all disassembled manually. When some hydraulic shock absorbers are difficult to replace due to changes in hydraulic stroke, manual disassembly using tools such as pry bars is required, which is time-consuming, inefficient, and can easily damage the hydraulic shock absorbers.

[0004] Disassembling hydraulic shock absorbers requires specialized tools: Disassembling hydraulic shock absorbers typically requires specialized tools such as jacks, caliper jacks, shock absorber spring removers, specific wrenches, and sockets. Without these tools, disassembly will be difficult and may damage the shock absorber or other components.

[0005] High technical requirements: The disassembly process requires an understanding of the vehicle or equipment structure and the installation method of the hydraulic shock absorber. The operation steps have strict requirements in sequence. Failure to be familiar with the operation procedures may result in failure to disassemble successfully or even cause safety problems. Utility Model Content

[0006] This utility model proposes a disassembly device for a hydraulic shock absorber with two operating modes: manual rotation of the handle or motor rotation of the handle. It can quickly solve the problem that when the hydraulic shock absorber is compressed upwards for disassembly due to its short stroke, the operator cannot compress the shock absorber upwards because the damping is too large, thus making disassembly impossible.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A disassembly device for a hydraulic shock absorber includes a rotating screw, an upper baffle plate mounted on the upper end of the rotating screw and fixed to the upper end of the hydraulic shock absorber, and a lower top plate movably mounted on the middle end of the rotating screw and fixed to the lower end of the hydraulic shock absorber. A fixing sleeve is provided on one side of the upper baffle, and the fixing sleeve is connected to the fixing nut at the upper end of the hydraulic shock absorber to prevent displacement during operation.

[0008] The lower top plate is connected to the rotating screw through the lower top plate sleeve to achieve vertical movement. The lower top plate has a U-shaped groove for fixing the lower end of the hydraulic shock absorber; the U-shaped groove matches the lower end of the hydraulic shock absorber.

[0009] A rotating handle is connected to the lower end of the rotating lead screw. A through hole is designed at the bottom of the rotating lead screw for installing the rotating handle, which is cylindrical and works in conjunction with the through hole.

[0010] The upper baffle is rotatably connected to the rotating lead screw via a bearing, and the upper end of the rotating lead screw is also provided with a top nut to prevent the rotating lead screw from disengaging.

[0011] A fixed handle is also fixedly connected to the middle section of the upper baffle.

[0012] The lower top plate sleeve has an internal thread, which matches the external thread of the rotating lead screw.

[0013] The lower end of the rotating lead screw is connected to a motor via a coupling assembly, enabling electric control.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model relates to a disassembly device for a hydraulic shock absorber. The top of the rotating screw is connected to the upper baffle bearing, allowing them to rotate relative to each other. The upper baffle is placed above the hydraulic shock absorber and fixed firmly. The rotating rod is screwed into the threaded hole on the inner side of the lower top plate, and the U-shaped groove on the outer side of the lower top plate is engaged with the bottom of the hydraulic shock absorber. By using a rotating handle or a motor, the rotating screw is driven to rotate. As the stroke between the upper baffle and the lower top plate is compressed, the height of the lower arm can be adjusted by rotating the handle below the tooling, allowing for rapid compression and disassembly of the primary hydraulic shock absorber.
