Shock absorber limiting ring seat point welding device and method for welding limiting ring seat through same

Abstract

A shock absorber limiting ring seat point welding device comprises a bottom plate, an electrode via hole is formed in one side of the bottom plate, a left locating device and a right clamping device are mounted at the left side and the right side of the electrode via hole respectively, and a supporting station of a workpiece is arranged on the left locating device and the right clamping device. The left locating device comprises a left supporting block, an adjusting sliding block, a limiting ring seat locating block and an adjusting jacking mechanism. The right clamping device comprises a right supporting block, a sliding block, a limiting ring seat clamping block and a limiting block, and the sliding block, the limiting ring seat clamping block and the limiting block are mounted on the right supporting block. A limiting ring seat spot welding method adopting the shock absorber limiting ring seat point welding device comprises the steps that S1, the device is mounted on a spot welder workbench; S2, a limiting ring seat is mounted; S3, a connecting rod is mounted; S4, the limiting ring seat is adjusted and clamped; S5, the dimension between the limiting ring seat and the upper end face of the connecting rod is adjusted and measured; S7, spot welding is carried out. The device is scientific in design, simple in structure and convenient to demount, fast clamping and accurate locating can be achieved, and the limiting ring seat spot welding method adopting the shock absorber limiting ring seat point welding device is easy and convenient to operate, high in efficiency, safe and reliable, and guarantees quality.

Description

technical field [0001] The invention relates to a shock absorber production equipment and method, in particular to a spot welding device for a limit ring seat of a shock absorber and a method for welding a limit ring seat with the same. Background technique [0002] The welding assembly of the connecting rod and the limiting ring seat is one of the important parts of the shock absorber. The longest stroke of the shock absorber is limited by welding the limiting ring seat on the connecting rod to prevent the shock absorber from being stretched. Overtravel causes the piston valve system structure installed on the connecting rod to collide with the guide on the end face of the shock absorber and damage it; currently, there is no special spot welding fixture in the production process of the shock absorber, and the method of spot welding the limit ring seat is : Put the limit ring seat and connecting rod together into the tooling sleeve first, and then put them on the electrode o...

Problems solved by technology

[0002] The welding assembly of the connecting rod and the limiting ring seat is one of the important parts of the shock absorber. The longest stroke of the shock absorber is limited by welding the limiting ring seat on the connecting rod to prevent the shock absorber from being stretched. Overtravel causes the piston valve system structure installed on the connecting rod to collide with the guide on the end face of the shock absorber and damage it; currently, there is no special spot welding fixture in the production process of the shock absorber, and the method of spot welding the limit ring seat is : Put the limit ring seat and connecting rod together into the tooling sleeve first, and then put them on the electrode of the welding machine together with the sleeve, and rely on manual work to balance the connecting rod, limit ring seat and sleeve on the electrode and then click Welding; the problems with this spot welding method are:

[0003] 1. The balance of human hands is poor, and it is difficult to ensure that the workpiece can be balanced on the electrode at all times. If it is slightly tilted, molten iron will splash during spot welding, which will easily cause burrs on the workpiece, and it is difficult to guarantee product quality;

[0004] 2. The safety is poor, and the splash of molten iron is easy to burn people;

[0005] 3. Workers are highly concentrated at work; production efficiency is low
