[0025] As shown in Figures 1 to 6 A sheet metal welding laser welding machine comprises a rack 1, a clamping assembly 2, a fixing assembly 3, a welding assembly 4 and an adjusting assembly 5.

[0026] Laser welding is a welding method that utilizes a laser to couple a high-energy laser beam into an optical fiber, transmits the laser beam through a collimating mirror to parallel light, and then focuses the parallel light on a workpiece to form a high-energy heat source, melts the material at the joint, and then forms a high-quality weld after rapid cooling of the liquid metal. According to the formation characteristics of the weld during welding, laser welding can be divided into heat conduction welding and laser deep penetration welding.

[0027] In addition, during sheet metal welding, laser welding can achieve high-precision positioning and welding, avoiding errors and deformation that can occur in traditional welding methods. At the same time, due to the fast speed and small heat-affected zone of laser welding, high-quality welds and small welding deformation can be obtained.

When it is necessary to clamp a workpiece, the first air cylinder 24 is activated to generate a pushing force. The pushing force is transmitted to the mounting strip 27 through the push block 26, so that the mounting strip 27 moves along the guide rails 22. With the movement of the mounting strip 27, it gradually approaches and contacts the workpiece. When the mounting strip 27 is in close contact with the workpiece, the clamping assembly 2 achieves clamping and positioning of the sheet metal part in the transverse direction.

The output end of the third cylinder 542 is fixedly connected with the material receiving table 543, and through the extension and retraction movement of the cylinder, the material receiving table 543 and the workpiece mounted thereon can be driven to move up and down or translate. The material receiving table 543 and the mounting seat 544 are rotationally connected, so that the material receiving table 543 can be rotationally adjusted within a certain range to meet the positioning requirements of different workpieces.

[0032] The adjuster 55 is composed of a fourth cylinder 551, a driven plate 552 fixedly installed at the end of the fourth cylinder 551, a limiting rod 553 fixedly installed at the side of the driven plate 552, an adjusting seat 554 fixedly installed on the material receiving plate 51, a fifth cylinder 555 rotationally installed on the adjusting seat 554, and a support seat 556 fixedly installed on the output end of the fifth cylinder 555.

[0035] The clamping assembly 2, the rack 1, the fixing assembly 3, the welding assembly 4 and the adjusting assembly 5 are each provided with two groups, and the second group is mirror-imaged along the short side of the base 41. By providing two groups of each assembly, under the action of the double stations, when one group of sheet metal parts is welded, the other group of sheet metal parts is subjected to the pre-treatment edge grinding process, so as to reduce the waiting time of the workpieces to be processed and improve the accuracy and efficiency of the laser welding.

[0036] Working principle:

[0037] In the initial state, the first cylinder 24 is in an inactive state, and the pushing block 26 and the mounting strip 27 are in the initial position. When it is necessary to clamp the workpiece, the first cylinder 24 is activated to generate a pushing force. The pushing force is transmitted to the mounting strip 27 through the pushing block 26, so that the mounting strip 27 moves along the guide rail 22. With the movement of the mounting strip 27, it gradually approaches and contacts the workpiece. The second cylinder 31 provides power to drive the mounting piece 32 and the mounting plate 33 at the bottom to move to the predetermined position along the slide rail 34. At the same time, the rotating motor works to drive the clamping plate 36 fixed on the output end to rotate, so as to realize the longitudinal stable clamping and accurate positioning of the sheet metal part, connect and fix other assemblies, and ensure the stability of the entire adjusting assembly 5. When the welding arm is fixed on the base 41, the welding assembly 4 positions the welding head 43 on the sheet metal part to be welded through the accurate movement of the mechanical arm 42, and then realizes the welding of the sheet metal part by using the laser generated by the welding head 43 and the gas environment.
