Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, and specifically to a dual-station switching mechanism for a laser welding machine. Background Technology

[0002] A laser welding machine is a highly efficient and precise welding device that utilizes the high energy density of a laser beam to weld workpieces. It focuses the laser beam onto a very small area, generating high temperatures in a short time, causing the materials to be welded to melt and fuse together rapidly. Laser welding machines offer advantages such as high welding speed, high weld quality, small heat-affected zone, minimal deformation, and simple operation. They are widely used in aerospace, automotive manufacturing, electronics, and medical device industries. A crucial component of a laser welding machine is the dual-station switching mechanism, which allows welding to be performed at one station while workpiece loading, unloading, and preparation are done at the other, significantly improving production efficiency.

[0003] According to patent document CN220407429U, a dual-station laser welding machine is disclosed, relating to the field of laser welding technology. This dual-station laser welding machine includes a welding frame adjustment assembly and a fixing assembly. An electric push rod is fixedly installed on the top of the welding frame, and a lifting plate is fixedly installed on the free end of the electric push rod. Two sets of welding machines are fixedly installed on the top of the lifting plate. This dual-station laser welding machine can rotate the workpiece during the welding process. This allows the workpiece to be positioned for welding using two sets of welding machines at different locations, reducing the time spent manually adjusting the workpiece and lowering the labor intensity of workers. Furthermore, through the coordinated use of a bidirectional lead screw, a moving block, a guide rod, and a connecting plate, the clamping plate can be moved to clamp the workpiece before welding, effectively reducing the amplitude of workpiece wobbling and preventing welding failures.

[0004] When switching between two stations, laser welding machines typically move the welding head to the other station. However, this method often results in low switching efficiency and may introduce errors during the movement, affecting welding accuracy. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a technical solution: it includes a welding table 1, and a workstation switching table 2 is fixedly connected to the middle of the top front side of the welding table 1.

[0024] Please see Figure 2-5The workstation switching platform 2 includes a workstation switching plate 21. Supporting side plates 22 are fixedly connected to the left and right sides of the bottom of the workstation switching plate 21. A motor placement plate 23 is fixedly connected to the center of the front side of the workstation switching plate 21. A motor 24 is fixedly connected to the top of the motor placement plate 23. Guide rods 25 are fixedly connected to both sides of the center of the top of the workstation switching plate 21. Guide grooves 26 are formed on both sides of the inner side of the two guide rods 25 on the top of the workstation switching plate 21. Arc-shaped guide grooves 27 are formed on both sides of the outer side of the two guide rods 25 on the top of the workstation switching plate 21. The output end of the motor 24 extends to the bottom of the motor placement plate 23 and is fixedly connected to a track 218. A turntable 216 is rotatably connected to the front side of the center of the bottom of the workstation switching plate 21. The track 218 is fitted onto the outer wall of the turntable 216 and the transmission disc 217. Sliding sliders 28 are slidably connected to the tops of the two guide rods 25. Guide grooves 26 are formed on both the front and rear sides of the top of the two sliders 28. There are slider grooves 29. The front sides of the two sliders 28 that are close to each other are fixedly connected to the moving control rods 210. The bottom ends of the two moving control rods 210 extend to the bottom sides of the workstation switching plate 21 through two guide grooves 26 and are fixedly connected to the drive shafts 211. The two drive shafts 211 are respectively attached to the inner sides of the track 218. The top of the two sliders 28 is movably connected to the welding part placement plate 212. The bottom of the two welding part placement plates 212 is slidably connected to the inner side of the two slider grooves 29 opened on the top of the sliders 28. The top rear side of the two welding part placement plates 212 is fixedly connected to the welding part placement disk 213. The rear side of the two welding part placement plates 212 that are far from each other is fixedly connected to the abutment rods 214. The bottom ends of the two abutment rods 214 are fixedly connected to the pulleys 215. The outer walls of the two pulleys 215 are slidably connected to the inner walls of the two arc-shaped guide grooves 27.

[0025] When welding is required, the weldment is first placed on top of two weldment placement trays 213 and fixed by the trays 213. One of the weldment placement trays 213 is welded on the inner side of the top plate 16 and the welding base plate 14. After the weldment fixed by the weldment placement tray 213 on the inner side of the top plate 16 and the welding base plate 14 is welded, the motor 24 is started. The motor 24 drives the track 218 to rotate, which in turn drives the turntable 216 and the transmission disc 217 to rotate. The transmission disc 217 drives two movement control rods 210 to move through two transmission shafts 211. The two movement control rods 210 drive two sliders 28 to slide on top of two guide rods 25. The two sliders 28 drive two weldment placement plates 212 to move on top of the two guide rods 25. When one of the weldment placement trays 212 is placed on top of the welding base plate 14, the welding is completed. When plate 212 moves to a side away from welding base plate 14, another welding component placement plate 212 is moved to the inside of top plate 16 and welding base plate 14. At the same time, during the station switching, the pulleys 215 at the bottom of the two abutment rods 214 slide on the inner wall of the two arc-shaped guide grooves 27, thereby guiding the movement of the two welding component placement plates 212. When the two welding component placement plates 212 are about to move to a parallel state, the pulleys 215 at the bottom of the two abutment rods 214 slide according to the curvature of the inner wall of the two arc-shaped guide grooves 27, so that the two welding component placement plates 212 move in opposite directions at the top of the slider 28 by the pull of the two abutment rods 214, thereby avoiding the collision of the two welding component placement plates 212 during the movement and ensuring the stability and safety of the welding components during the welding process.

[0026] Please see Figure 2-5The welding table 1 includes a base plate 11. Two support rods 12 are fixedly connected to the left and right sides of the top rear side of the base plate 11. Connecting plates 13 are fixedly connected to the top of the two sets of support rods 12. Welding base plates 14 are fixedly connected to the bottom of the two connecting plates 13. Second support rods 15 are fixedly connected to the front and rear sides of the top of the two connecting plates 13 on the side closest to each other. A top plate 16 is fixedly connected to the top of the two sets of second support rods 15. A robotic arm 117 is fixedly connected to the middle of the right side of the top of the base plate 11. An L-shaped limiting component connecting block 17 is fixedly connected to the middle of the front side of the top plate 16. A hydraulic push rod connecting plate 18 is fixedly connected to the top of the L-shaped limiting component connecting block 17. Guide rods 19 are fixedly connected to both sides of the top of the hydraulic push rod connecting plate 18. A hydraulic push rod connecting rod 110 is fixedly connected to the inner side of 19. A hinge block 113 is fixedly connected to the top front side of the hydraulic push rod connecting plate 18. A hydraulic push rod 111 is fixedly connected to the rear side of the hydraulic push rod connecting rod 110. A push block 112 is fixedly connected to the bottom end of the hydraulic push rod 111. A V-shaped rotating rod 114 is rotatably connected to the front side of the push block 112. The middle of the outer wall of the V-shaped rotating rod 114 is rotatably connected to the inner wall of the hinge block 113. A second support rod 15 is provided in the middle of the bottom front side of the L-shaped limiting component connecting block 17. A mechanical arm 117 is fixedly connected to the middle right side of the top of the base plate 11. An inverted L-shaped limiting rod 116 is rotatably connected to the bottom front side of the V-shaped rotating rod 114. The outer wall of the inverted L-shaped limiting rod 116 is slidably connected to the inner wall of the groove 115.

[0027] When the welded component moves to the inside of the welding base plate 14 and the top plate 16, the hydraulic push rod 111 is activated to pull the push block 112 upward inside the guide rod 19. This, in turn, pulls the V-shaped rotating rod 114 around the hinge block 113. At this time, the other end of the V-shaped rotating rod 114 pushes the inverted L-shaped limiting rod 116 downward along the inner wall of the groove 115. The bottom of the inverted L-shaped limiting rod 116 extends and engages with the welded component inside the welding base plate 14 and the top plate 16. The receiving plate 212 is used for limiting and fixing to prevent the welded parts from shifting during the welding process and improve welding accuracy. When it is necessary to switch the work station, simply control the hydraulic push rod 111 to push the push block 112 downward, so that the V-shaped rotating rod 114 rotates in the opposite direction and the inverted L-shaped limiting rod 116 releases the welded parts. In addition, when switching the work station, the welded parts can be taken out or placed by the robotic arm 117, thereby realizing automated welding, reducing the tediousness of manual operation, and further improving welding efficiency.

[0028] Working principle: When welding is required, the welding part is first placed on top of two welding part placement trays 213 and fixed by the welding part placement trays 213. One of the welding part placement trays 213 is welded on the inner side of the top plate 16 and the welding base plate 14. After the welding of the welding part fixed by the welding part placement tray 213 on the inner side of the top plate 16 and the welding base plate 14 is completed, the motor 24 is started. The motor 24 drives the track 218 to rotate. The track 218 drives the turntable 216 and the transmission disc 217 to rotate. The transmission disc 217 drives the two moving control rods 210 to move through the two transmission shafts 211. The two moving control rods 210 drive the two sliders 28 to slide on top of the two guide rods 25. The two sliders 28 drive the two welding part placement plates 212 to slide on top of the two guide rods 25. When one of the welding component placement plates 212 moves to a side away from the welding base plate 14, the other welding component placement plate 212 is moved to the inside of the top plate 16 and the welding base plate 14. At the same time, during the work station switching, the pulleys 215 at the bottom of the two abutment rods 214 slide on the inner wall of the two arc-shaped guide grooves 27, thereby guiding the movement of the two welding component placement plates 212. When the two welding component placement plates 212 are about to move to a parallel state, the pulleys 215 at the bottom of the two abutment rods 214 slide according to the curvature of the inner wall of the two arc-shaped guide grooves 27, so that the two welding component placement plates 212 move in opposite directions at the top of the slider 28 by the pull of the two abutment rods 214, thereby avoiding the collision of the two welding component placement plates 212 during the movement.

[0029] When the welded part moves to the inside of the welding base plate 14 and the top plate 16, the hydraulic push rod 111 is activated to pull the push block 112 to move upward inside the guide rod 19. Then, the push block 112 pulls the V-shaped rotating rod 114 to rotate around the hinge block 113. At this time, the other end of the V-shaped rotating rod 114 pushes the inverted L-shaped limiting rod 116 to slide downward along the inner wall of the groove 115. The bottom of the inverted L-shaped limiting rod 116 extends out and limits and fixes the welded part placement plate 212 inside the welding base plate 14 and the top plate 16, preventing the welded part from shifting during the welding process and improving the welding accuracy. When it is necessary to switch the work position, simply control the hydraulic push rod 111 to push the push block 112 downward, so that the V-shaped rotating rod 114 rotates in the opposite direction and the inverted L-shaped limiting rod 116 releases the welded part. In addition, when switching the work position, the welded part can be taken out or placed by the robotic arm 117.
