Description

Technical Field

[0001] This utility model relates to the field of welding and fixing technology, and more specifically, it relates to a vehicle welding switching device for a welding production line. Background Technology

[0002] Existing welding production lines typically require clamping mechanisms to position and fix the vehicle body when welding different car models to ensure stability during the welding process. However, most existing clamping mechanisms are fixed installations, lacking flexible adjustment capabilities. When the production line needs to switch between different car models, the fixed clamping mechanisms often cannot effectively adapt due to differences in the structural dimensions of each model, resulting in clamping position deviations or insufficient clamping force, which affects welding accuracy and stability. Furthermore, manually adjusting or replacing fixtures for different car models is not only time-consuming and labor-intensive but also reduces the efficiency of the production line. Therefore, there is an urgent need to design a car model welding switching device for welding production lines to improve the flexibility of the production line and the welding quality.

[0005] Preferably, a slider is slidably connected in the inclined groove, and an abutment plate is connected to the side wall of the slider. The abutment plate is slidably connected to the inclined groove, and the design of the abutment plate facilitates fixing the clamping mechanism in the adjustment hole.

[0006] Preferably, the other side wall of the slider is connected to three sets of abutment springs, and the other end of the abutment spring is connected to a threaded plate. The inner side wall of the threaded plate is provided with a threaded groove, and the locking or unlocking state of the clamping mechanism is realized by the cooperation of the threaded plate and the threaded rod.

[0007] Preferably, a rotating groove is provided on the top inner side of the fixed cylinder, and a rotating disk is rotatably connected in the rotating groove. This design provides the flexibility of rotation, allowing the operator to adjust the position of the clamping mechanism through simple rotation, which enhances the ease of operation and adaptability of the equipment and reduces the complexity of the operation process.

[0008] Preferably, the upper surface of the rotating disk is connected to a rotating plate, and the upper surface of the rotating plate is connected to a hexagonal block. This design, through the connection of the hexagonal block, allows the operator to easily operate the adjustment of the clamping device using standard tools, improving the efficiency of the adjustment process and facilitating quick adaptation to the needs of different vehicle models.

[0009] Preferably, the lower end face of the rotating disk is connected to a threaded rod, and the surface of the threaded rod is provided with multiple sets of threaded strips adapted to the threaded groove. The cooperation between the threaded rod and the threaded plate ensures that the clamping device can be stably adjusted in position, avoiding unstable clamping force caused by loose or deviated threads.

[0010] Preferably, a limiting groove is provided at the bottom of the inner side of the fixed cylinder, and a limiting plate is connected to the lower end face of the threaded rod. The limiting plate is embedded in the limiting groove and rotatably connected to the limiting groove.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a vehicle model welding switching device for a welding production line, which has the following beneficial effects: The vehicle model welding switching device for a welding production line provided by the present invention can effectively solve the problem of improper adaptation of clamping mechanism caused by vehicle model differences in the prior art. Specifically, the device can quickly adjust the position of the clamping mechanism according to the size and structural requirements of different vehicle models through the adjustment hole and the adjustable clamping mechanism, so as to ensure that the workpiece can be stably clamped during the welding process, thereby improving production efficiency.

[0012] The adjustable clamping mechanism allows it to adapt to different workpiece models, eliminating the need for customized clamping devices for each vehicle model. Operators simply need to adjust the clamping mechanism's fixed position by rotating the hexagonal block according to the specific parameters of the vehicle model. This allows the clamping device to be adapted quickly and easily, reducing the time required for changing fixtures and improving production line efficiency. The rubber pads inside the clamp effectively prevent damage to the workpiece while ensuring sufficient clamping force, keeping the workpiece stable during welding and avoiding quality problems caused by unstable clamping. Furthermore, the unlocking mechanism of the clamping mechanism is designed to be very simple. After welding, operators can release the clamp by simply rotating the hexagonal block in the opposite direction, allowing the clamp to quickly retract and facilitating workpiece removal.

[0013] In summary, the welding production line vehicle model welding switching device provided by this invention improves the flexibility and efficiency of the production line, adapts to the needs of different workpiece models, reduces the difficulty and time cost of manual operation in the production process, and can reduce equipment wear and extend service life.

[0019] Please see Figures 1-5A welding production line vehicle welding switching device includes a welding frame 11 with multiple sets of adjustment holes 12 on its surface; it also includes a clamping mechanism, which includes a fixed cylinder 21 adapted to the adjustment holes 12. An installation sleeve 22 is fitted onto the outer surface of the fixed cylinder 21, and a clamp 23 is connected to the side wall of the installation sleeve 22. A rubber pad 24 is connected to the lower end of the clamp 23. Multiple inclined grooves 25 are formed on the inner side wall of the fixed cylinder 21, and a slider 26 is slidably connected within each inclined groove 25. An abutment plate 27 is connected to the side wall of the slider 26 and slidably connected to the inclined groove 25. Three abutment springs 28 are connected to the other side wall of the slider 26. The other end is connected to a threaded plate 29. The inner side wall of the threaded plate 29 is provided with a threaded groove 210. The top of the inner side of the fixed cylinder 21 is provided with a rotating groove 211. A rotating disk 212 is rotatably connected in the rotating groove 211. A rotating plate 213 is connected to the upper end face of the rotating disk 212. A hexagonal block 214 is connected to the upper end face of the rotating plate 213. A threaded rod 215 is connected to the lower end face of the rotating disk 212. The surface of the threaded rod 215 is provided with multiple sets of threaded strips 216 that are adapted to the threaded groove 210. A limiting groove 217 is provided at the bottom of the inner side of the fixed cylinder 21. A limiting plate 218 is connected to the lower end face of the threaded rod 215. The limiting plate 218 is embedded in the limiting groove 217 and rotatably connected to the limiting groove 217.

[0020] In this utility model, the clamping mechanism can be adjusted in position via the adjustment hole 12 to adapt to different vehicle models. Multiple clamping mechanisms are provided; only one is shown in the figure. Before welding, the operator places the workpiece to be welded onto the welding frame 11, and then adjusts the position of the clamping mechanism according to the workpiece model. Specifically, the fixing cylinder 21 of the clamping mechanism is inserted into the adjustment hole 12. Then, the operator rotates the hexagonal block 214 using an external tool. The hexagonal block 214 drives the rotating plate 213, along with the threaded rod 215 below, to rotate synchronously. The limiting plate 218 also rotates in the limiting groove accordingly. The internal rotation of 217 causes the threaded plate 29 to rotate, which drives multiple sets of threaded plates 29 to move via the threaded bar 216. The threaded plate 29 drives the corresponding slider 26 to slide along the inclined groove 25 towards the larger diameter end of the inclined groove 25 via the abutment spring 28. The slider 26 drives the abutment plate 27 to move synchronously. The abutment plate 27 gradually extends out of the inclined groove 25 and tightly abuts against the inner wall of the adjustment hole 12, thereby fixing the clamping mechanism. Then, by adjusting the clamp 23, the rubber pad 24 is pressed against the surface of the workpiece to clamp and fix the workpiece. After all the clamping mechanisms are installed in sequence, the welding work can begin. After the welding work is completed, the worker can rotate the hexagonal block 214 in the opposite direction. The hexagonal block 214 drives the rotating plate 213, along with the rotating disk 212, the threaded rod 215 and the limiting plate 218 to rotate synchronously. The threaded rod 215 drives the slider 26 to slide along the inclined groove 25 towards the end of the inclined groove 25 with a smaller diameter through the threaded plate 29. The abutment spring 28 is compressed, and the slider 26 drives the abutment plate 27 to move synchronously, so that the abutment plate 27 is received into the inclined groove 25. This releases the tight abutment state between the abutment plate 27 and the inner wall of the adjusting hole 12. After that, the worker can pull out the clamping mechanism, release the clamping and fixing of the workpiece, and take off the workpiece, thus completing the welding work of one workpiece.
