Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration damper manufacturing technology, specifically to a welding device for a cylindrical vibration damper. Background Technology
[0002] Telescopic shock absorbers are a core component of automotive suspension systems. They use hydraulic damping to attenuate vibrations between the chassis and body during compression and extension strokes, improving ride comfort and handling stability. Their structure consists of an oil reservoir, a working cylinder, a piston, and multiple valves. Damping force is generated by controlling the flow path of the hydraulic fluid, converting vibration energy into heat energy for dissipation. Based on the adjustment method, they can be classified as passive, mechanically adjustable, and electronically controlled. The production and processing of telescopic shock absorbers requires welding equipment. However, some existing telescopic shock absorber welding equipment requires a considerable amount of time to change welding fixtures when welding multiple different parts. Furthermore, the parts cannot be rotated during welding; operators must move the welding torch to ensure complete welding, which wastes production time and affects the efficiency of the equipment.
