[0002] Laser welding machine, also commonly known as laser welding machine, laser welding machine, is a machine used for laser welding in material processing. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses to the inside of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc. It has a high aspect ratio, a small weld width, a small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welds, no post-welding treatment or only simple treatment, high weld quality, no pores, can be precisely controlled, small focused light spot, high positioning accuracy, and easy automation.

[0003] In the prior art, when two tubular parts are welded by a laser welding machine, they usually need to be clamped and fixed by a clamp. However, the existing clamp needs to be tightened manually to complete the clamping of the tubular part during use, which makes the operation of clamping and fixing the tubular part cumbersome and prone to errors during adjustment. At the same time, when the welded product is subsequently taken out, it is necessary to manually adjust the clamping again, which makes it inconvenient to quickly remove the product from the clamp, thereby not only reducing work efficiency but also reducing welding accuracy.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 - Figure 3 As shown, in this embodiment, in order to facilitate the clamping and fixing of the tubular member by the rotating clamping device 3 and rotate it during welding, the purpose of completing the rapid and accurate welding and fixing of the tubular member can be achieved, and the specific use principle of the rotating clamping device 3 in conjunction with the laser welding machine body 2 is as follows:

[0020] Place the two tubular parts to be welded together in the inner ring 17 of the fixed ring 9 on both sides of the top surface of the machine 1, respectively, and turn on the cylinder 19 installed between the connecting plates 18 on the outer wall of the inner ring 17. The cylinder 19 drives the output end to push the arc clamping plate 20 inward, and the tubular parts can be quickly clamped and fixed in the inner ring 17 through the arc clamping plate 20. Next, turn on the electric push rod 6 installed on the outer wall of the side seat 5 on the left and right sides of the top surface of the machine 1. The electric push rod 6 drives the output end to push the movable seat 7 inward, and the sliding block 8 installed on the bottom surface of the movable seat 7 opens on the top surface of the machine 1. The slide block 8 will slide in the sliding groove 4, and the sliding block 8 will drive the fixing ring 9 to move inward on the top surface of the machine table 1. At this time, the symmetrical fixing ring 9 will make a relative movement operation until the fixed pipe-shaped parts in the inner ring 17 in the fixing ring 9 are butted together. Therefore, the two pipe-shaped parts can be clamped and fixed on the same axis after the butt joint, so as to ensure the progress of the subsequent welding of the pipe-shaped parts. Then, when the laser welding machine body 2 is turned on, the laser welding head of the laser welding machine body 2 moves to the position where the two pipe-shaped parts are butted to weld the butt joint. When welding, the mounting plate installed on the top surface of the fixing ring 9 is turned on. The drive motor 15 on the inner wall of the seat 11 drives the output end to drive the gear 16 to rotate. Since the gear 16 is meshed with the outer gear ring 14 installed on the outer wall of the rotating ring 12, the gear 16 will drive the outer gear ring 14 to rotate under the meshing action, and the outer gear ring 14 will drive the rotating ring 12 to rotate in the ring of the fixed ring 9. During the rotation, the T-arc slider 13 installed on the outer wall of the rotating ring 12 will slide in the T-shaped ring groove 10 opened on the inner wall of the fixed ring 9. At the same time, the tubular The parts will rotate with the rotation of the rotating ring 12, and the welding operation of the butt joints of the two pipe-shaped parts will be quickly completed during the rotation process. After welding, the cylinder 19 is started again to drive the output end to drive the arc clamping plate 20 to move outward, and the pipe-shaped parts will no longer be clamped and fixed, so that the staff can quickly take down the finished product after welding, thereby achieving the purpose of quickly clamping and fixing the pipe-shaped parts for butt welding, without the need to manually clamp and disassemble the pipe-shaped parts by adjusting the clamp, thereby not only facilitating the clamping and taking of the pipe-shaped parts, but also improving the welding accuracy and welding efficiency of the pipe-shaped parts.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, various improvements may be made to the present invention and its components may be replaced by equivalents, or some of its technical features may be replaced by equivalents without departing from the scope of the present invention. All that is within the spirit and principles of the present invention should be included in the protection scope of the present invention.
