Description

Technical Field

[0001] The invention relates to the technical field of shock absorber bracket welding, in particular to a shock absorber spring bracket welding device. Background Art

[0002] Shock absorber spring bracket welding refers to the process of fixing the spring bracket and other components (such as arc-shaped connecting pieces) together through welding. This welding process usually uses arc welding, laser welding or other welding methods to connect the metal materials after melting at high temperature to ensure a firm combination of the components. The shock absorber spring bracket is a key component in the shock absorption system. Traditional shock absorber spring bracket welding mainly relies on arc welding technology. The high temperature generated by the arc heats the contact surface of the bracket and the connecting piece to a molten state to form a firm metal joint. The operator manually controls the position and speed of the welding gun to ensure the uniformity and quality of the welded joint. This process relies on experience and operating techniques, so the welding quality is greatly affected by the operator's skills and environmental factors. Although traditional shock absorber spring bracket welding can avoid some deformation caused by thermal expansion and welding force, it still has some disadvantages. During the welding process, manual operation may lead to unstable welding accuracy and welding deviation. Manual control is difficult to achieve completely consistent stress distribution.
