End cover auxiliary welding device for air cylinder machining

Abstract

An end cover auxiliary welding device for air cylinder machining comprises a base, and the surface of the base is vertically provided with a first supporting plate in a fixed mode and slidably connected with a second supporting plate; the first supporting plate and the second supporting plate are arranged in a spaced mode; the outer side of the second supporting plate is connected with a second pneumatic rod, the top of the interior of the first supporting plate is rotationally provided with a first end cover positioning mechanism in a penetrating mode, the top of the interior of the second supporting plate is rotationally provided with a second end cover positioning mechanism in a penetrating mode, and mirror images of the first end cover positioning mechanism and the second end cover positioning mechanism are symmetrically arranged; and the surface of the base is provided with a driving mechanism, and the driving mechanism is in engagement connection with the first end cover positioning mechanism and the second end cover positioning mechanism. According to the end cover auxiliary welding device, an end cover of an air cylinder is sucked and fixed with negative pressure through the two end cover positioning mechanisms located on the left side and right side, accordingly, end cover falling and deviation are avoided, a cylinder body can be conveniently assembled on an end cover,and quick assembling of the end cover and the cylinder body is achieved.

Description

technical field [0001] The invention belongs to the technical field of gas storage tanks, in particular to an auxiliary welding device for end caps used for processing gas storage tanks. Background technique [0002] The air storage tank is the gas storage device in the automobile braking system; the air storage tank is used to store the gas compressed by the air compressor (air pump), and is used in automobile braking, whistle and other systems; [0003] During the processing of the gas storage tank, two end caps need to be welded and fixed on both ends of the cylinder body, so as to seal the two ends of the cylinder body and form a complete shape of the gas storage tank; the current automatic welding equipment is mainly fixed horizontally, vertically Directional welding method, the horizontal clamping device drives the assembled end cover cylinder to rotate, and the vertical welding torch performs automatic welding on the rotating end cover; [0004] Since there is no pos...

AI Technical Summary

Problems solved by technology

[0004] Since there is no positioning structure when the end cap and the cylinder are assembled, the end cap and the cylinder are both arc-shaped and smooth, which makes it easy to loosen after the end cap and the cylinder are matched, and the end cap is easy to fall off. The alignment set in the early stage is very laborious. In addition, it is necessary to complete the end caps at both ends at the same time, and the force can only be applied from the outside. The operator needs to repeatedly operate and align multiple times to achieve this. It takes a long time and affects the processing efficiency. During welding, the end caps will also be partially misplaced, and the welding quality is not easy grasp
