Device and process for backstep welding of damping spring disk

Abstract

The invention relates to the technical field of welding, particularly to a device and a process for backstep welding of a damping spring disk. The device comprises a rotary table, a locating plate, a vertical plate, a rotating cylinder, a liquid storage cylinder pressing plate, a spring disk locating pin long seat locating plate, a spring disk locating pin long seat, a spring disk locating pin, a spring disk pressing plate, a spring disk locating round pin, a spring disk locating long pin, a spring disk locating pin seat, a liquid storage cylinder locating plate, and a reinforcement plate. Compared with the prior art, the disk is three-point located by the aid of a tooling and fixedly clamped through the rotating cylinder, welding thermal deformation after welding is reduced, dimensions after the welding are stable and reliable, and adjustment is convenient. The structure of the device for the backstep welding of the spring disk is simple and stable, the maintenance cost is low, and the device is convenient to maintain.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to equipment and technology for reverse welding of damping spring discs. Background technique [0002] Traditionally, the same direction welding process is used for the welding of spring discs. The same direction welding process is simple. Put the spring disc into the liquid storage cylinder with the bottom cover pressed and put it into the fixture. Press the start button of the equipment, the safety door is automatically closed, the workpiece is automatically clamped, the fixture is turned and tilted at 45 degrees, two fixed welding torches enter the torch at the same time and weld the spring plate and the bottom cover, the equipment turntable rotates 370 degrees, and the workpiece is automatically released after welding. The torch and clamp return to their original positions. This kind of process method spring plate welding and bottom cover welding are synchronized, and the man-...

AI Technical Summary

Problems solved by technology

Therefore, the process method can only be two processes of spot welding and positioning, and then strengthening welding. Welding cannot be carried out continuously for a week, which makes it easy to have appearance defects such as weld flow and weld bead. The important thing is that it is not easy to form effective penetration on the workpiece. The spring plate is easy to pull off under load and other major quality problems
