Double station annular pipe fitting circumferential laser welding machine and method

Abstract

The invention discloses a double station annular pipe fitting circumferential laser welding machine and a method. The double station annular pipe fitting circumferential laser welding machine comprises a mounting bracket mounted on the surface of a wall. Two first clamping shells are symmetrically arranged at the lower end of the mounting bracket, a connecting plate is jointly and fixedly connected to the middle positions of the upper ends of the two first clamping shells, a lifting mechanism for moving the first clamping shells up and down is arranged between the connecting plate and the mounting bracket, two ends of each first clamping shell are rotatably connected to second clamping shells through rotating shafts, closing mechanisms are arranged between the first clamping shells and thesecond clamping shells, device slots are formed in the inner sides of the first and second clamping shells, and the device slots are formed circumferentially in a spaced manner. The double station annular pipe fitting circumferential laser welding machine is simple in structure, can carry out laser welding to annular pipefittings of different models, and is suitable for welding and processing ofvarious pipefittings of different apertures, so that the annular pipefitting is welded favorably and the structural stability is good.

Description

technical field [0001] The invention relates to the technical field of laser welding machines, in particular to a double-station annular pipe fitting circumferential laser welding machine and method. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and sma...

Problems solved by technology

However, the laser welding machine equipped with a rotary laser welding head has a complex structure and poor stability. It is difficult to perform laser welding on different types of annular pipe fittings, which is not conducive to the welding process of annular pipe fittings.
