Automatic girth welding device for air cylinder for automobile

Abstract

The invention discloses an automatic girth welding device for an air cylinder for an automobile. The automatic girth welding device comprises a base, wherein two symmetric machine seats on the base, an air cylinder bracket located between the two machine seats, and clamping mechanisms separately arranged on the two machine seats, wherein each clamping mechanism comprises a clamping cylinder, a mobile box seat and an air cylinder end cover clamp; piston rods of the clamping cylinders are connected with the outer sides of the mobile box seats; the air cylinder end cover clamps are arranged on the inner sides of the mobile box seats; the mobile box seats are further provided with servo motors; the servo motors are connected with rotating shafts arranged along the axial direction of the air cylinder through transmission devices; the rotating shafts are connected with the air cylinder end cover clamps; a cylinder body of the air cylinder is arranged on the air cylinder bracket; the clamping cylinders push the air cylinder end cover clamps to move towards the direction of the cylinder body of the air cylinder, so that air cylinder end covers are clamped with the cylinder body of the air cylinder; the servo motors are started to enable the air cylinder end cover clamps to drive the whole air cylinder to rotate and be subjected to welding; after the air cylinder rotates a circle, girth welding is completed; and furthermore, the automatic girth welding device is high in efficiency and high in quality.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to an automatic girth welding device for an automotive gas cylinder. Background technique [0002] The air storage tank is a gas storage device in the automobile braking system, which is used to store the gas compressed by the air compressor. The gas storage tank is generally composed of the cylinder body and the end caps at both ends. The welding quality often determines the airtightness, compressive strength and other properties of the gas storage tank. At present, most of the gas storage tanks are still produced by manual welding. On the one hand The efficiency is low. On the other hand, the welding quality depends entirely on the welding worker's operation level, resulting in uneven quality. Contents of the invention [0003] The object of the present invention is to provide an automatic girth welding device for a gas tank for automobiles, which can perform g...
