Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a welding positioning device for an automobile door trim panel. Background Art

[0002] An automobile door trim panel is a plate structure for decorating a car door, mainly including a door interior trim panel and a triangular trim panel. The back of the triangular trim panel is directly injection-molded, and there are at least two circular columns. Installation holes are opened at positions on the door interior trim panel corresponding to the columns on the back of the triangular trim panel. A nylon retaining ring is sleeved on the installation holes. The triangular trim panel is installed on the door interior trim panel through the interference fit between the columns and the nylon retaining ring. When welding the automobile door panel, a manual hot welding gun is used to melt and weld the welding points one by one.

The other end of the connecting rod 13 is fixedly connected to a clamping block 14, so that the connecting rod 13 drives the sliding of the clamping block 14. First springs 15 are fixedly connected to the opposite sides of the two clamping blocks 14 to apply an elastic force to the clamping blocks 14.

[0034] A second motor 16 is fixedly installed at the rear side of the middle part of the mounting plate 4. The output end of the second motor 16 is fixedly connected to a threaded rod 17 to facilitate driving the threaded rod 17 to rotate. The rear end of the outer side of the threaded rod 17 is threadedly connected to a scraping rod 18 to scrape the welding slag. The top end of the rear side of the scraping rod 18 is fixedly connected to a fixing plate 19 for installing a cleaning brush 23. The bottom end of the fixing plate 19 is fixedly connected to a plurality of connecting pipes 20. The inner side of the connecting pipes 20 is slidably connected to a pressing block 21. The other end of the connecting pipe 20 is fixedly connected to a second spring 22. The bottom ends of the plurality of pressing blocks 21 are fixedly connected to a cleaning brush 23 to facilitate increasing the elastic force of the cleaning brush 23 and facilitating the pushing of the cleaning brush 23 to increase the adaptability to the mounting plate 4. Installation grooves 24 are provided on both the left and right sides of the top end of the mounting plate 4.

The inner sides of the fixed pipes 25 are slidably connected to a pushing block 26. The bottom ends of the inner sides of the installation grooves 24 are fixedly connected to a plurality of pushing springs 27. The other ends of the pushing springs 27 are fixedly connected to the bottom ends of the pushing blocks 26 to facilitate the pushing of the pushing blocks 26, thereby facilitating the pushing of the bottom ends of the components in the irregular door panel, thereby improving the stability of the components. A dirt receiving box 28 is fixedly connected to the front side of the mounting plate 4 to facilitate the discharge of the scraped welding slag. The outer side of the sliding block 7 is slidably connected to the inner sides of the two upper and lower chutes 5. The other end of the first spring 15 is fixedly connected to the inner side of the fixed housing 12 to improve the stability of the first spring 15.

The other end of the threaded rod 17 is rotatably connected to the middle part of the front side of the mounting plate 4 to improve the stability of the rotation of the threaded rod 17.

[0035] Working principle: When in use, place the automotive door panel component to be clamped and positioned at the middle of the top of the mounting plate 4. Then, according to the height of the automotive door panel component, pull the connecting rod 13, so that the connecting rod 13 drives the clamping block 14 to be pulled out of the engaged clamping groove 11, causing the clamping block 14 to squeeze the first spring 15, thus releasing the clamping state between the clamping block 8 and the adjusting block 9. Then, pull the adjusting block 9, so that the adjusting block 9 slides inside the clamping block 8 to adjust the height. After adjustment, release the pulled connecting rod 13. Under the pushing action of the first spring 15 on the clamping block 14, the clamping block 14 engages with the corresponding clamping groove 11, thereby fixing the position of the adjusting block 9. Then, start the first motor 2. When the first motor 2 drives the rotating block 3 to rotate, the rotating block 3 pulls the rotating rods 6 on both sides to rotate, causing the rotating rods 6 on both sides to pull the sliding blocks 7 at the other ends to slide inside the multiple sliding grooves 5, so that the two sliding blocks 7 drive the two clamping blocks 8 to approach each other, thereby clamping the automotive door panel component. This facilitates the flexible adjustment of the height of the clamping surface in the clamping device according to the height of different parts in the automotive door panel, improves the adaptability when the welding positioning device clamps and positions the automotive door panel component, enhances the stability during clamping, and reduces the welding difficulty. Then, during cleaning, start the second motor 16 to drive the threaded rod 17 to rotate, which facilitates the threaded rod 17 to drive the scraping rod 18 to scrape the surface of the mounting plate 4. When the scraping rod 18 scrapes, it drives the rear fixing plate 19 to move. Under the action of the second spring 22, it drives the extrusion block 21 to squeeze the cleaning brush 23, improving the fit between the cleaning brush 23 and the mounting plate 4, facilitating the cleaning and scraping of the welding debris falling on the surface of the positioning device, reducing the long-term residual welding slag on the surface of the positioning device, forming hard nodules and scratches, which may cause the device to be worn and the welding positioning device to be damaged.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
