Automatic welding equipment

Abstract

The invention discloses automatic welding equipment, and relates to the technical field of welding equipment. The automatic welding equipment comprises a barrel, and a driving cavity and a moving cavity are sequentially formed in the barrel from one end to the other end. Through mutual cooperation of a supporting driving motor, a threaded lead screw, a transmission sliding block, a transmission supporting ring and a supporting roller, the equipment can enter pipe fittings with different pipe diameters for inner girth welding, the influence of the depth of the pipe fittings is avoided, the use condition of the equipment is reduced, and the situation that the equipment cannot be used due to the large depth of the pipe fittings is avoided, so that the equipment is more practical and convenient to popularize; and through mutual cooperation of a displacement driving motor, a first double-groove belt pulley, a second double-groove belt pulley, a second lifting arm, a grooved roller and a second triangular belt, the equipment can be moved to a to-be-welded position, the situation that the welding effect is affected due to the fact that the equipment is unstable during welding is avoided, the quality of welding seams is improved, and the service life of the pipe fittings is prolonged.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, in particular to an automatic welding equipment. Background technique [0002] Circular seam welding of pipe fittings is a common type of welding in welding technology. The circular seam is usually divided into inner circular seam and outer circular seam. For pipe fittings with high load-bearing strength, in order to ensure the strength of the workpiece, the form of double circular seam welding on the inner and outer surfaces is generally adopted. Most of the circular seam welding machine systems on the market are aimed at the outer ring The inner circular seam welding machine usually relies on the welding arm to extend into the pipe for inner circular seam welding. However, relying on the welding arm to extend into the pipe for inner circular seam welding, the length of the welding arm is limited, and the depth cannot be adjusted. Larger pipe fittings are welded with inner girth seam,...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an automatic welding equipment to solve the existing problem: relying on the welding arm to extend into the pipe fittings for inner circular seam welding, the length of the welding arm extending into the pipe is limited, and it is impossible to carry out internal welding on pipe fittings with a large depth. Circumferential welding makes the device only usable under specific conditions, which makes the device not practical enough and not convenient for the popularization of the device
