Abstract

The invention relates to the technical field of centering of welding machines, in particular to a centering structure of a straight seam welding machine, and aims to solve the problem that the welding quality of a workpiece is affected due to the fact that the straight seam welding machine in the prior art is difficult to center the workpiece and poor in effect. The centering structure comprises a mounting plate and a vertical air cylinder, a hinge mechanism is hinged to a piston rod of the vertical air cylinder, the hinge mechanism is connected with a transverse plate, a centering clamping sleeve is mounted on the bottom face of the transverse plate, a first centering cutter is mounted in the centering clamping sleeve, and a second centering cutter capable of sliding in the height direction of the first centering cutter is mounted on the side face of the first centering cutter. And a plurality of horizontal power mechanisms which sequentially penetrate through the transverse plate and the centering clamping sleeve and are connected with the second centering cutter are mounted on the transverse plate. The side face of the workpiece is attached to the side face of the second centering cutter, so that the side face of the second centering cutter can be used as a reference face, the workpiece can be centered more easily, and the quality of the welded workpiece is higher.

Description

technical field [0001] The invention relates to the technical field of centering of welding machines, and more specifically relates to a centering structure of straight seam welding machines. Background technique [0002] The straight seam welding machine is an automatic welding equipment that realizes the automatic completion of the straight line weld of the welding workpiece through automation and mechanization. The straight seam welding machine is also called the straight seam automatic welding machine, and the longitudinal seam automatic welding machine is a kind of automatic welding machine , can replace labor in large quantities, greatly improve production efficiency and welding quality, reduce labor costs, and improve the working environment of welders, such as corner seam welding of large transformer shells, straight seam welding of large cylinders, and straight seams of solar water heaters Welding, straight seam welding of steel strips on the production line, weldin...
