Description

Technical Field

[0001] This invention relates to the field of automotive parts welding tools, specifically a welding station device for welding automotive parts. Background Technology

[0002] With the rapid development of the times, automobiles have become the mainstream means of transportation in today's society. During automobile production, the parts used for assembly are an important part of the internal structure of the automobile. They connect the automobile tightly together, making the whole automobile more stable and robust. During the production process, automobile parts need to be welded using a welding station.

[0003] For example, the Chinese patent with the number CN114102015A, "A welding table device for welding automotive parts", includes a stand and a storage structure. A connecting plate is fixedly connected to the top of the stand, and a worktable is fixedly connected to the top of the connecting plate. An electromagnetic adsorption structure is provided on the inner right side of the worktable. The electromagnetic adsorption structure includes an electromagnetic panel, and the electromagnetic panel is attached to the worktable.

[0004] In the aforementioned patent, although the electromagnetic panel is opened to allow falling debris to be attracted to the surface, and some easily rolling metal parts are then attracted to the electromagnetic panel for positioning, thus enhancing the positioning effect of the metal parts, the welding slag generated during the welding process is at a high temperature. After falling onto the workbench and being attracted by the electromagnetic force, it is easy to stick to the surface of the workbench and is relatively difficult to separate. This makes subsequent cleaning more cumbersome, increases the cleaning time of the workbench, and reduces cleaning efficiency, thereby reducing welding efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a welding table device for welding automotive parts, in order to solve the problems mentioned in the background art. For example, when the switch in front of the control panel of the electromagnetic adsorption structure is turned on to activate the electromagnetic panel, the electromagnetic panel starts to work and generates magnetic force to magnetically attract and adsorb the welding debris. However, some problems still exist. The welding debris generated during the welding process is at a high temperature. After falling onto the worktable and being attracted by the electromagnetic force, it is easy to stick to the surface of the worktable and is difficult to separate. This makes the subsequent cleaning more cumbersome, increases the cleaning time of the worktable surface, and reduces the cleaning efficiency, thereby reducing the welding efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, during the rotation of the two lead screws, four moving blocks located on the outer surfaces of the two lead screws move towards the center. During the movement of the four moving blocks, two scrapers move at the top of the welding table body, scraping off the welding slag that has fallen and adhered to the column on the welding table body. Under the push of the scraper 5, the slag finally enters the collection tank, realizing the rapid removal and collection of welding slag on the surface of the welding table. At the same time, it can scrape off the welding slag that adheres to the surface of the welding table, making the cleaning speed fast and convenient.

[0018] 2. In this invention, during the movement of the four moving blocks driven by the lead screw, the movable rods located inside the four No. 1 bearing seats are pushed and rotated by the moving blocks. During the rotation of the four movable rods, the fixed platform is lifted and the two gear columns are rotated. As the gear columns rotate, the six gears meshing with them move in the six mounting slots respectively and drive the six fixed seats to separate, releasing the fixation of the car parts. Conversely, the same principle applies. This realizes the replacement of welded car parts while cleaning the desktop, greatly improving welding and cleaning efficiency.

[0019] 3. In this invention, the second geared motor starts and drives the worm gear to rotate. During the rotation of the worm gear, it drives two gears to rotate. Under the drive of the gears, the rotating shaft rotates, thereby driving the adjusting rod to rotate. During the rotation of the adjusting rod, the adjusting rod slides inside the adjusting through hole and moves the support column upward inside the sleeve column, raising the welding table body. After being raised to the specified height, the rotation of the second geared motor is stopped for fixing. This realizes the adjustment of the height of the welding table, enabling the welding table to be used under different conditions and improving the practicality of the device.

[0030] In this embodiment, when the welding table body 1 needs to be cleaned, the two No. 1 reduction motors 30 start simultaneously, causing the two lead screws 3 to rotate. During the rotation of the two lead screws 3, the four moving blocks 4 located on the outer surface of the two lead screws 3 move towards the center. During the movement of the four moving blocks 4, the two scrapers 5 move at the top of the welding table body 1, scraping off the welding slag that has fallen and stuck to the column on the welding table body 1. Under the push of the scrapers 5, the slag finally enters the collection tank 18 and eventually falls into the collection box 20. After the collection box 20 is full, the handle 3... 2. The collection box 20 is pulled out from the placement groove 19. The moving block 4 can move inside the slide groove 2 by setting the lead screw 3. The first gear motor 30 can provide power to the lead screw 3. The scraper 5 can remove the welding slag on the surface of the welding table body 1. The triangular scraper 6 can make the welding slag at the edge move towards the center. The collection groove 18 can collect the welding slag pushed in by the scraper 5. The placement groove 19 can fix the collection box 20. The handle 32 can be used to easily pull out the collection box 20. Example 2

[0031] Figure 1-5 As shown, each of the four movable blocks 4 has a No. 1 bearing seat 7 fixedly connected to its top. Each of the four No. 1 bearing seats 7 has a movable rod 8 rotatably installed inside. A fixed platform 10 is located at the top and center of the welding table body 1.

Fixed seats 14 are slidably installed inside each of the six square through holes 12. Mounting grooves 15 are provided on both sides of the fixed platform 10 at the locations of the six square through holes 12. Gear rods 13 are slidably installed inside each of the six mounting grooves 15. The bottom ends of the six gear rods 13 are respectively connected to the outer surfaces of the two gear rods 9. The six toothed rods 13 are fixedly installed at the top and bottom of the six fixed seats 14 respectively. Support plates 11 are fixedly installed at the bottom and on both sides of the fixed platform 10. The bottom of the two support plates 11 is in contact with the top of the welding platform body 1. Placement plates 21 are fixedly connected to the inner side and near the bottom of three fixed seats 14. Storage slots 22 are opened on the inner side and near the bottom of the remaining three fixed seats 14. One end of the three placement plates 21 is movably inserted into the three storage slots 22 respectively. Limiting rods 17 are fixedly connected to both sides of the six toothed rods 13. Limiting slots 16 are opened on both sides of the six mounting slots 15. The twelve limiting slots 16 are slidably installed on the outer surface of the twelve limiting rods 17 respectively. The width of the mounting slots 15 is the same as the width of the toothed rods 13.

[0032] In this embodiment, during the movement of the four moving blocks 4 driven by the lead screw 3, the movable rods 8 located inside the four bearing seats 7 are pushed and rotated by the moving blocks 4. During the rotation of the four movable rods 8, the fixed platform 10 is lifted and the two toothed columns 9 are rotated. As the toothed columns 9 rotate, the six toothed rods 13 meshing with them move in the six mounting slots 15 respectively and drive the six fixed seats 14 to separate, releasing the fixation of the automobile parts. Conversely, the same applies. By setting the support plate 11, it is beneficial to ensure the stability of the fixed platform 10. By setting the limiting slot 16 and the limiting rod 17, the toothed rods 13 can be effectively fixed. By setting the placement plate 21, support force can be given to the automobile parts before they are clamped and fixed. By setting the movable rods 8, the fixed platform 10 can be moved up and down. By setting the square through hole 12, the fixed seat 14 is positioned. Example 3

[0033] according to Figure 1 , Figure 6 and Figure 7As shown, support columns 23 are fixedly installed at the bottom of the welding table body 1 and at the four corners. Each of the four support columns 23 has a movably sleeved connecting column 24 at its bottom. Each of the four sleeve columns 24 has an adjustment through hole 25 through it on one side. I-shaped fixing rods 31 are fixedly installed inside the four sleeve columns 24. Two rotating shafts 27 are rotatably installed at the top of the I-shaped fixing rods 31 and at the middle position. Gears 28 are fixedly installed on the outer surface of the two rotating shafts 27 respectively. A worm gear 29 meshes between the two gears 28. A second geared motor is rotatably connected to the bottom of the worm gear 29. Adjusting rods 26 are fixedly installed at both ends of the two rotating shafts 27. The other ends of the four adjusting rods 26 are rotatably installed at the bottom of the four support columns 23 respectively. Four No. 3 bearing seats are fixedly installed at the top of the I-shaped fixing rods 31 and near the two side edges. The two ends of the two rotating shafts 27 are rotatably installed inside the four No. 3 bearing seats respectively. The internal size of the adjustment through hole 25 is the same as the width of the adjusting rod 26. The internal size of the sleeve column 24 is the same as the size of the support column 23.

[0034] In this embodiment, when the height of the welding table body 1 needs to be adjusted, the second gear motor starts and drives the worm gear 29 to rotate. During the rotation of the worm gear 29, the two gears 28 rotate, and the rotating shaft 27 rotates under the drive of the gears 28, thereby driving the adjusting rod 26 to rotate. During the rotation of the adjusting rod 26, the adjusting rod 26 slides inside the adjusting through hole 25 and slides the support column 23 inside the sleeve column 24 and moves it upward, raising the welding table body 1. After raising it to the specified height, the second gear motor stops rotating and is fixed. By setting the third bearing seat, the position of the rotating shaft 27 is fixed to prevent skewing. By setting the adjusting through hole 25, the adjusting rod 26 can move inside the sleeve column 24.

[0035] The operating method and working principle of this device are as follows: When cleaning the welding table body 1 is required, the two No. 1 reduction motors 30 start simultaneously, causing the two lead screws 3 to rotate. During the rotation of the two lead screws 3, the four moving blocks 4 located on the outer surface of the two lead screws 3 move towards the center. During the movement of the four moving blocks 4, the two scrapers 5 move at the top of the welding table body 1, scraping off the welding slag that has fallen and stuck to the column. Under the push of the scrapers 5, the slag eventually enters the collection tank 18 and finally falls into the collection box 20. At the same time, during the movement of the moving blocks 4, the movable rods 8 located inside the four No. 1 bearing seats 7 are pushed by the moving blocks 4 and rotate. During the rotation of the four movable rods 8, the fixed platform 10 is lifted and the two geared columns 9 rotate. As the geared columns 9 rotate... The six gears 13 meshing with it move in the six mounting slots 15 respectively and drive the six fixed seats 14 to separate, releasing the fixation of the car parts. Conversely, after the collection box 20 is full, the collection box 20 is pulled out from the mounting slot 19 by the handle 32. When it is necessary to adjust the height of the welding table body 1, the second gear motor starts and drives the worm gear 29 to rotate. During the rotation of the worm gear 29, it drives the two gears 28 to rotate. Under the drive of the gears 28, the rotating shaft 27 rotates, thereby driving the adjusting rod 26 to rotate. During the rotation of the adjusting rod 26, the adjusting rod 26 slides in the adjusting through hole 25 and the support column 23 slides in the sleeve column 24 and moves upward, raising the welding table body 1. After being raised to the specified height, the second gear motor stops rotating and is fixed.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
