Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically a double-sided laser composite welding device. Background Technology

[0002] Laser-arc hybrid welding combines two heat sources—laser and electric arc—to achieve greater weld penetration and a more efficient, high-quality welding process. It leverages the characteristics of both laser and electric arc to overcome the shortcomings of individual laser welding and electric arc welding. It combines the advantages of both independent heat sources (e.g., laser heat sources have high energy density, excellent directivity, and transparent dielectric properties; electric arc plasma has high thermo-electric conversion efficiency, low equipment and operating costs, and mature technology), while largely avoiding their drawbacks (e.g., laser energy loss due to the high reflectivity of metallic materials, high equipment costs, and low electro-optical conversion efficiency; and electric arc heat sources have lower energy density and poor discharge stability at high speeds). Furthermore, the organic combination of the two sources generates many new characteristics (high energy density, high energy utilization, high arc stability, lower tooling preparation precision, and improved workpiece surface quality), making it a promising new welding heat source.

[0003] Currently, traditional laser composite welding devices only have a single laser welding head, which cannot weld workpieces quickly, resulting in low work efficiency and reduced productivity. Therefore, a double-sided laser composite welding device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided laser composite welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided laser composite welding device, comprising a base plate, on which a first fixing frame and a second fixing frame are fixedly connected, and a connecting rod is provided between the first fixing frame and the second fixing frame. A servo motor is provided on the side of the first fixing frame, and a rotating rod is rotatably connected to the output end of the first servo motor. One end of the rotating rod passes through the right side of the first fixing frame and is rotatably connected to the left side of the second fixing frame. A moving block is provided on the outer surface of the rotating rod, and a fixed block is provided on the lower surface of the moving block. A T-shaped groove is formed on the lower surface of the fixed block, and a T-shaped groove is formed on the side of the fixed block. A stepper motor is provided, and a bidirectional screw is rotatably connected to the output end of the stepper motor. One end of the bidirectional screw passes through the front of the fixed block and is rotatably connected to the rear inner wall of the T-shaped slide groove. A slider is provided inside the T-shaped slide groove. A connecting post is provided on the lower surface of the slider, and a positioning block is provided on the lower surface of the connecting post. A laser head, a welding torch, and a wire feeder are respectively provided on the lower surface of the positioning block. A steel plate is provided below the laser head. A pad is provided on the upper surface of the base plate. A limit groove is formed on the surface of the base plate. A geared motor is provided on the side of the base plate. The output of the geared motor... A bidirectional screw is rotatably connected to the end of the first limiting groove. One end of the bidirectional screw passes through and is rotatably connected to the left side wall of the first limiting groove. A slider is provided on the outer surface of the bidirectional screw. A positioning plate is provided on the upper surface of the slider. A limiting block is provided on the upper surface of the positioning plate. A clearance groove is provided on the side of the limiting block. A reduction motor is provided on the top of the limiting block. A rotating shaft is provided at the output end of the reduction motor. One end of the rotating shaft passes through and is rotatably connected to the bottom wall of the first clearance groove. A movable plate is provided on the outer surface of the rotating shaft. A limiting plate is fixedly connected to the side of the movable plate. A clearance groove is provided on the side of the limiting plate. There is a servo motor 2, the output end of which is provided with a rotating rod 2, one end of which is provided with a positioning block 2, and a limit groove 2 is provided on the side of the positioning block 2. A stepper motor 2 is provided on the top of the positioning block 2, the output end of which is provided with a rotating shaft 2, and a clamping block is provided on the outer surface of the rotating shaft 2. A connecting block is provided on the side of the positioning block 2, and a clearance groove 2 is provided on the side of the connecting block. A synchronous motor is provided on the side of the synchronous motor, and a rotating rod 3 is provided on the output end of the synchronous motor. One end of the rotating rod 3 passes through and is rotatably connected to the left side wall of the clearance groove 2. A clamping plate is provided on the outer surface of the rotating rod 3.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Preferably, the number of clamps is four, with two clamps forming a group. The two groups of clamps are symmetrically arranged on both sides of the steel plate. By providing clamps, the clamps can control the vertical steel plate before welding the two steel plates, aligning the welding surfaces of the two steel plates and preventing deformation during welding.

[0008] Preferably, the second rotating shaft is a bidirectional screw, and there are four second rotating shafts. Two second rotating shafts form a group, and the two groups of second rotating shafts are symmetrically arranged. Each group of second rotating shafts has two clamping blocks on its outer surface. The two clamping blocks are symmetrically arranged. With the second rotating shaft and the clamping blocks, the second reduction motor drives the second rotating shaft to rotate, so that the two clamping blocks move synchronously, thereby enabling the clamping blocks to clamp the workpiece and prevent the workpiece from shifting during welding.

[0009] Preferably, there are two positioning blocks, connecting columns, and sliders, arranged symmetrically. Each positioning block has a laser head, welding torch, and wire feeder on its lower surface. With these components, the servo motor can be controlled to move the rotating rod, causing the positioning block to simultaneously weld the laser head, welding torch, and wire feeder on both sides of the steel plate. A stepper motor can also rotate a bidirectional screw, which in turn moves the slider. This movement of the slider moves the connecting column, causing the positioning block to move, facilitating adjustment of the welding spacing.

[0010] Preferably, there are two servo motors, which are symmetrically arranged on both sides of the steel plate. By setting the servo motors, when one side of the steel plate is welded, the servo motors can be controlled to drive the positioning block to rotate, so that the positioning block drives the clamping block to rotate the steel plate, thereby welding the other side of the steel plate.

[0011] Preferably, there are two sliders, which are symmetrically arranged, and each slider has a limit block on its surface. With the sliders, the geared motor drives the bidirectional screw to rotate, which in turn moves the sliders, allowing the clamping block to be adjusted according to the size of the steel plate.

[0012] Beneficial effects

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The double-sided laser composite welding device is equipped with a servo motor, a rotating rod, a moving block, a servo motor, a positioning block, and a clamping block. The servo motor drives the rotating rod to rotate, which in turn causes the moving block to move the two positioning blocks. This, in turn, causes the two positioning blocks to move the laser head, welding gun, and wire feeder, enabling simultaneous welding of both sides of the steel plate. After one side of the steel plate is welded, the servo motor can be controlled to rotate the positioning block, which in turn causes the clamping block to move the steel plate to the unwelded side for welding. This allows the double-sided laser composite welding device to perform rapid welding of workpieces, improving both work efficiency and productivity. Attached Figure Description

This, in turn, moves the limiting plate 29, which in turn moves the positioning block 32. The positioning block 32 then lowers the clamping block 36 to the appropriate position. The steel plate 17 is then placed on the pad 18 using a tool. Finally, the second stepper motor 35 drives the second rotating shaft 34 to rotate, which in turn clamps the steel plate 17 onto the clamping block 36. Hold the steel plate 17, and then use the synchronous motor 40 to drive the rotating rod 41 to move the clamping plate 42, so that the clamping plate 42 clamps the vertical steel plate 17.
