Steel tube end plate welding machine

Abstract

The invention provides a steel tube end plate welding machine, and belongs to the technical field of machinery. The problem that an existing welding machine is insufficient in steel tube clamping and positioning precision is solved. The steel tube end plate welding machine comprises a rack, wherein a clamping and positioning assembly used for clamping and positioning the top of a steel tube is installed on the rack, a welding operation assembly and a top face positioning backer used for positioning the top face of the steel tube are arranged above the clamping and positioning assembly, and the top face positioning backer is connected with the rack through a driving element; the driving element can enable a top face positioning backer to avoid the area over the steel tube clamped by the clamping and positioning assembly. The clamping and positioning assembly clamps the top of the steel tube, so that the distance between the clamped and positioned part of the steel tube and the top face is small, the influence of bending deformation of the steel tube on the clamping precision is reduced, and the clamping and positioning precision of the end of the steel tube is improved. The positioning mode of the steel tube end plate welding machine is suitable for clamping and positioning steel tubes with different lengths, the positions of the upper ends of the steel tubes are consistent, and the steel tube end plate welding machine has the advantages of flexible machining and high machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and relates to a welding machine, in particular to a steel pipe end plate welding machine. Background technique [0002] A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. Steel pipes are used in a wide range of applications, such as furniture, heating equipment, etc. When steel pipes are used, they usually need to be cut according to a set length and end plates are used to cover the ports of the steel pipes. Steel pipes usually have bending deformation in the axial direction, which makes the precision of parts clamping and positioning low, that is, there is a deviation in the position of the end face of the parts. The matching degree of the moving trajectory is low, so that there are problems such as low welding quality and low welding qualification rate in the welding of steel pipe end plates. [0003] Taking the heat ...

AI Technical Summary

Problems solved by technology

Steel pipes usually have bending deformation in the axial direction, which makes the accuracy of parts clamping and positioning low, that is, there is a deviation in the position of the end face of the parts, and the moving track of the welding head is fixed during automatic welding, which leads to the actual welding seam and the welding head. The matching degree of moving trajectory is low, so that there are problems such as low welding quality and low welding qualification rate in the welding of steel pipe end plates

[0003] Taking the heat dissipation pipe in the heating equipment as an example, the end plate of the heat dissipation pipe needs to be sealed after welding to avoid water leakage, that is, the welding requirements of the end plate of the heat dissipation pipe are relatively high, and the current automatic welding equipment cannot guarantee the integrity of the heat dissipation pipe. Quality requirements; thus manual welding of the end plate of the heat pipe has the problems of low production efficiency, high labor intensity and high processing cost
