[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1, please refer to Figures 1-7 This embodiment provides a laser welding device for automotive shift forks, including: a housing 1; a disc 2, the disc 2 being rotatably connected to the top of the housing 1; A limiting block 31 is fixedly connected to the top of the disc 2. A mounting groove 32 and a sliding groove 320 are provided in the middle of the disc 2. A rectangular frame 33 is slidably connected inside the mounting groove 32. A hydraulic chamber 34 is fixedly connected inside the rectangular frame 33. Hydraulic rods A35 and B37 are slidably connected inside the two ports of the hydraulic chamber 34. A positioning block 36 and a moving plate 38 are fixedly connected to the other ends of hydraulic rods A35 and B37, respectively. An inclined groove 39 is provided on the outer wall of the moving plate 38. A sliding plate 310 is slidably connected inside the sliding groove 320. A sliding shaft 3 is fixedly connected to the outer wall of the sliding plate 310. 11. An arc-shaped clamping plate 312 is fixedly connected to the upper end of the skateboard 310. An L-shaped plate 313 is fixedly connected to the bottom of the disc 2. A dual-axis motor is fixedly connected to the inner side of the L-shaped plate 313. A connecting rod A314 and a ratchet 316 are fixedly connected to the two output ends of the dual-axis motor, respectively. A connecting rod B315 is hinged to the other end of the connecting rod A314. The other end of the connecting rod B315 is hinged to the rectangular frame 33. A toothed ring 317 is fixedly connected to the bottom of the disc 2. A pawl 318 is hinged to the inner wall of the toothed ring 317. A circular opening is provided at the bottom of the base 1. A toothed ring 319 is fixedly connected to the inner wall of the circular opening.

[0027] A spring A is fixedly connected to the inner wall of the toothed ring 317, and the other end of the spring A is fixedly connected to the pawl 318. This connection method ensures that the spring A can stably perform its function, while forming a controllable linkage between the toothed ring 317 and the pawl 318, thereby achieving the expected functional performance during mechanical operation. The toothed ring 317 is located inside the toothed ring 319, and the toothed ring 317 meshes with the toothed ring 319, thereby achieving effective transmission of force and motion. The end of the sliding shaft 311 away from the slide plate 310 is slidably connected inside the inclined groove 39.

[0028] In use, first place the car shift fork on the upper end of the disc 2, so that its vertical surface abuts against the limit block 31, then start the lower output end of the dual-axis motor, and then its bottom output end will drive the connecting rod A314 to rotate. Then the connecting rod B315 at the other end of the connecting rod A314 will push the rectangular frame 33 to slide inside the mounting groove 32, and then the hydraulic chamber 34 located inside the rectangular frame 33 will also move accordingly. Then the hydraulic rods A35 and B37, which are slidably connected in the two ports of the hydraulic chamber 34, will also move accordingly. When the hydraulic rod A35 moves, the positioning block 36 at its end contacts one side of the shift fork. As the rectangular frame 33 continues to move, the hydraulic oil inside the hydraulic chamber 34 is squeezed, pushing the hydraulic rod B37 to move away from the hydraulic chamber 34, thereby driving the moving plate 38 to move. The inclined groove 39 on the outer wall of the moving plate 38 exerts a force on the sliding plate 310 through the sliding shaft 311, causing the sliding plate 310 to slide in the sliding groove 320. The arc-shaped clamping plate 312 at the upper end of the sliding plate 310 then approaches the shift fork, and finally cooperates with the positioning block 36 to clamp and fix the shift fork, realizing the rapid positioning and clamping of the shift fork, ensuring that the shift fork will not be displaced during the welding process. Then, the car shift fork can be welded. When the position of the car shift fork needs to be adjusted, the upper output end of the dual-axis motor is started, which drives the ratchet 316 to rotate. When the ratchet 316 rotates, it pushes the pawl 318, which drives the gear ring 317 to rotate. Since the gear ring 317 meshes with the gear ring 319, the rotation of the gear ring 317 will drive the disc 2 to rotate on the top of the housing 1, thereby realizing the position adjustment of the shift fork. When the ratchet 316 rotates in the opposite direction, the pawl 318 separates from the ratchet 316 under the action of the spring A, and the gear ring 317 will not rotate with it, thus avoiding the shift fork from rotating in the opposite direction due to misoperation during the welding process.

[0029] Example 2, please refer to Figures 1-7 Based on embodiment 1, the upper end of the disc 2 is equipped with a flipping assembly 4. The flipping assembly 4 includes a reciprocating screw 41, which is fixedly connected to the upper end of the ratchet 316. A circular sleeve 42 is threadedly connected to the outer wall of the reciprocating screw 41. A limit ring 43 is rotatably connected to the bottom of the circular sleeve 42. A lifting plate 44 is fixedly connected to the upper end of the limit ring 43. An movable groove 45 is opened inside the lifting plate 44, and a slot 47 is opened on the outer wall of the circular sleeve 42. The movable groove 45 is internally slidably connected to a sliding block 48, and the side of the lifting plate 44 is hinged to a movable block 410. The upper end of the movable groove 45 is provided with a limit groove 46, and the inside of the limit groove 46 is fixedly connected to a spring B49. The other end of the spring B49 is fixedly connected to the movable block 410. The outer wall of the movable block 410 is fixedly connected to an electric turntable 411, and the outer wall of the electric turntable 411 is fixedly connected to an electromagnetic plate 412.

[0030] The upper end of the disc 2 is fixedly connected to a limit rod 413, and the lifting plate 44 is slidably connected to the outer wall of the limit rod 413. The limit rod 413 plays a key role in positioning and guiding.

[0031] In use, although the reciprocating screw 41 will rotate regardless of the direction of the ratchet 316's rotation, the circular sleeve 42 will not rise or fall with it because it is not limited in the initial state. When it is necessary to flip the car shift fork, the ratchet 316 first rotates in a direction that will not drive the toothed ring 317, flipping the movable block 410, electric turntable 411 and electromagnetic plate 412 inward. Then the movable block 410 will be squeezed and slid into the movable groove 45. When the slot 47 on the outer wall of the circular sleeve 42 coincides with the movable groove 45, the movable block 410 will enter the slot 47. At this time, the circular sleeve 42 is restricted and cannot continue to rotate. It can only move up and down with the rotation of the reciprocating screw 41. When the reciprocating screw 41 rotates, the circular sleeve 42 moves downward along its outer wall, simultaneously driving the limiting ring 43 and the lifting plate 44 to descend synchronously. During the descent, the lifting plate 44, through the cooperation of the sliding block 48 in the movable slot 45 and the movable block 410, causes the electric turntable 411 and the electromagnetic plate 412 to gradually approach and contact the clamped car shift fork. At this time, the electromagnetic plate 412 is energized to generate magnetic force, which attracts the surface of the shift fork. Then, the reciprocating screw 41 continues to rotate, causing the circular sleeve 42 to drive the lifting plate 44 and other components to rise and reset. When it rises to a certain height, the electric turntable 411 starts, driving the shift fork to rotate 180 degrees, realizing the flipping operation of the shift fork. After the flipping is completed, the reciprocating screw 41 continues to rotate, causing the circular sleeve 42 to drive the lifting plate 44 and other components to descend. When it descends to a suitable height, the electromagnetic plate 412 is de-energized, releasing the shift fork, thus realizing the flipping of the car shift fork.

[0032] Example 3, please refer to Figures 1-7 Based on embodiment 1, a dust collection assembly 5 is assembled on the upper end of the disc 2. The dust collection assembly 5 includes a vacuum cleaner 51. The suction end of the vacuum cleaner 51 is fixedly connected to a vacuum pipe 52. The other end of the vacuum pipe 52 is fixedly connected to a vacuum cover 53. A connecting rod 54 is fixedly sleeved on the outer wall of the vacuum pipe 52. The other end of the connecting rod 54 is fixedly connected to a moving block 56. A connecting rod C57 is hinged to the bottom of the lifting plate 44. The other end of the connecting rod C57 is hinged to the moving block 56.

[0033] A fixed frame 55 is fixedly connected to the upper end of the disk 2, and a movable block 56 is slidably connected inside the fixed frame 55, so that the movable block 56 can move freely inside the fixed frame 55 while maintaining the stability of the overall structure, thereby achieving a more precise and reliable motion control effect.

[0034] The height of the connecting rod 54 is higher than the highest point of the reciprocating screw 41, which means that during equipment operation, the connecting rod 54 is always located in the area above the reciprocating screw 41, thereby ensuring that there is no interference or collision between the two.

[0035] In use, when the lifting plate 44 descends, it drives the moving block 56 to slide inside the fixed frame 55 via the connecting rod C57. The moving block 56 drives the suction pipe 52 and the suction hood 53 to move synchronously via the connecting rod 54, so that the suction hood 53 can prevent the suction of dust generated during the welding process. When the lifting plate 44 rises, the connecting rod C57 pulls the moving block 56 to slide in the opposite direction, and the suction hood 53 returns to its original position, preventing the suction assembly 5 from interfering with the workspace when the equipment is idle or when other operations are being performed. This design, which is linked with the lifting plate 44, ensures that the position of the suction hood 53 is always adapted to the welding area, effectively improving the collection efficiency of welding fumes, reducing pollution to the working environment, and also reducing the risk of operators inhaling fumes.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
