[0022] Please see Figure 1-4 This utility model provides a technical solution: a welding device for producing automotive parts with anti-shaking features, including a workbench 1, a robotic arm 2, and a welding gun 3. A mounting frame 4 is fixedly connected to the top of the workbench 1. A bidirectional screw 5 is movably mounted between the mounting frames 4. A threaded slider 6 is movably connected to the bidirectional screw 5. A movable seat 7 is fixedly connected to the top of the threaded slider 6. A first motor 8 is fixedly connected to the threaded slider 6. An adjusting shaft 9 is fixedly connected to the output shaft of the first motor 8 through a coupling. A mounting block 10 is fixedly connected to the outer wall of the adjusting shaft 9 at the top of the movable seat 7.

[0023] An electric push rod 11 is fixedly connected to the top of the mounting block 10. A bracket 12 is fixedly connected to the output end of the electric push rod 11. A second motor 13 is fixedly connected to one side of the bracket 12. The output shaft of the second motor 13 is fixedly connected to a locking pin 14 via a coupling. A locking tube 15 is movably connected to the outer wall of the locking pin 14. A locking groove 16 is opened on the inner wall of the locking tube 15. A positioning seat 17 is fixedly connected to one end of the locking tube 15. A sleeve 18 is fixedly connected to the top of the positioning seat 17. An adjusting rod 19 is movably connected to the inner wall of the sleeve 18. A pressing block 20 is fixedly connected to one end of the adjusting rod 19. This allows for positioning operations during the welding of automotive parts, ensuring stable connection during processing and preventing shaking that could affect welding accuracy. The positioning process also allows for adjustment according to the welding angle requirements, effectively improving welding stability and enabling angle adjustment to meet different usage needs and enhance applicability, thus bringing convenience to welding work.

[0024] In this embodiment, the outer wall of the locking post 14 is provided with several locking blocks, and the locking blocks are arranged in a ring at equal intervals on the outer wall of the locking post 14. The locking post 14 fits against the inner wall of the locking tube 15 through the locking blocks, so that the locking tube 15 and the locking post 14 can be disassembled and assembled. This makes it convenient to replace the positioning seat 17 after disassembling and assembling the locking post 14, so that the shape of the positioning seat 17 can be changed to meet the positioning needs of automotive parts of different shapes, effectively improving practicality. Example

[0025] Based on Embodiment 1, a preferred embodiment of the anti-shake welding apparatus for automobile parts production provided by this utility model is, for example... Figures 1 to 4 As shown: the outer wall of the adjusting rod 19 is provided with an outward thread, the inner wall of the sleeve 18 is provided with an inward thread, and the adjusting rod 19 and the sleeve 18 are threaded together. The adjusting rod 19 can be rotated to move downward so that the clamping block 20 can firmly position the part.

[0026] In this embodiment, the movable seat 7 is fixed in an arc shape on the upper surface of the threaded slider 6. The movable seat 7 includes a central hole, and a bearing is installed inside the central hole. The inner ring of the bearing is connected to the adjusting shaft 9, and the adjusting shaft 9 is movably connected to the movable seat 7 through the bearing, so that the adjusting shaft 9 and the movable seat 7 can be movably installed, thereby allowing the adjusting shaft 9 to rotate stably.

[0027] Furthermore, a bearing is provided at the end of the bidirectional screw 5 away from the handle, and the outer ring of the bearing is fixedly connected to the mounting bracket 4. One end of the bidirectional screw 5 is movably connected to the mounting bracket 4 through the bearing, which allows the bidirectional screw 5 to be movably installed with the mounting bracket 4, thereby enabling the bidirectional screw 5 to rotate stably and adjust the mating distance of the parts.

[0028] Furthermore, there are two threaded sliders 6, each with a protrusion at the bottom. The two threaded sliders 6 are mounted outside the bidirectional screw 5 about the vertical center of the worktable 1, and the protrusions at the bottom of the two threaded sliders 6 are connected to the mounting bracket 4, which can play a limiting and guiding role when the threaded sliders 6 move.

[0029] In use, the automotive parts to be welded are installed in the positioning seats 17 on the left and right sides respectively. The adjusting rod 19 is rotated through the threaded engagement with the sleeve 18 to position the bottom abutment block 20 for the automotive parts. Then, the two threaded sliders 6 are adjusted to move closer by rotating the bidirectional screw 5, so that the two positioned automotive parts can be joined together, which brings stability to the subsequent welding process and avoids welding errors caused by shaking. Before welding, the first motor 8 and the second motor 13 can be started respectively according to the welding angle. The first motor 8 drives the adjusting shaft 9 to rotate, which makes the mounting block 10 rotate, thereby driving the positioning seat 17 to rotate left and right. At the same time, the second motor 13 adjusts the positioning seat 17 to rotate back and forth, so that the angle can be adjusted according to the welding requirements during positioning, which effectively improves the welding stability and meets different usage requirements, thus improving applicability.
