Description

Technical Field

[0001] This utility model relates to the field of wheel rim welding technology, and in particular to a wheel rim welding joint tightening device. Background Technology

[0002] A wheel rim, commonly known as a wheel hub, is a component on a wheel that mounts and supports the tire, forming the wheel together with the spokes. During the manufacturing process, a sheet metal plate is first bent into a circular shape. However, the bent rim is open, requiring welding at the joint. Current welding techniques often require two workers to push the open rim inward until the joint is aligned before welding. This method is not only time-consuming and labor-intensive, but also prone to increasing the product defect rate due to uneven or improper force application. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a wheel rim welding joint tightening device, which is achieved through the following technical solution:

[0004] A wheel rim welding joint tightening device includes a welding table, each of the four corners of the top of the welding table is provided with a support leg, and the top of all the support legs is provided with a support plate. The welding table is provided with a workpiece clamping mechanism, and the support plate is connected to a welding joint tightening mechanism.

[0005] The workpiece clamping mechanism includes a positioning device located at the front end of the welding table and a baffle located at the rear end of the welding table corresponding to the positioning device. The positioning device includes an "L"-shaped push-pull plate, which includes a vertically arranged positioning plate and a connecting plate that fits against the welding table. The connecting plate is fixedly connected to the welding table.

[0006] The welding joint tightening mechanism includes a telescopic cylinder, which is fixedly connected to the middle of the support plate. The telescopic cylinder is provided with a telescopic rod, and a connecting plate is fixedly connected to the bottom of the telescopic rod. A shock-absorbing cylinder is provided at the connection between the connecting plate and the telescopic rod. A tightening wheel is provided at each of the left and right ends of the bottom of the connecting plate.

[0007] As a preferred embodiment, the welding station is provided with a support leg at each of the four corners of its bottom.

[0008] As a preferred embodiment, each of the left and right ends of the connecting plate is provided with a pair of connecting ears, and each of the tightening wheels is located between the pair of connecting ears. The tightening wheels and the connecting ears are connected by a short shaft.

[0009] As a preferred embodiment, the connecting plate is provided with several vertically oriented waist holes 1, and the welding table is provided with waist holes 2 corresponding to the waist holes 1. Bolts pass through waist holes 1 and waist holes 2 to fix the connecting plate and the welding table.

[0010] Compared with existing technologies, the advantages of this invention are: it enables automatic tightening at the rim interface, and during the mating process, the rim is subjected to uniform force, preventing unnecessary deformation. This improves efficiency, saves time and labor, and reduces the defect rate.

[0011] The tightening wheel and the connecting lug are connected by a short shaft, which allows the tightening wheel to rotate. This prevents the tightening wheel from generating excessive friction with the rim when it presses inward against the opening of the rim, thus avoiding unnecessary deformation of the rim.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0021] A wheel rim welding joint tightening device includes a welding table 1, with a support leg 101 at each of the four corners of the top of the welding table 1, and a support plate 102 on the top of all the support legs 101. A workpiece clamping mechanism 2 is provided on the welding table 1, and a welding joint tightening mechanism 3 is connected to the support plate 102.

[0022] The workpiece clamping mechanism 2 includes a positioning device 4 located at the front end of the welding table 1 and a baffle 5 located at the rear end of the welding table 1 corresponding to the positioning device 4. The positioning device 4 includes an "L"-shaped push-pull plate 41, which includes a vertically arranged positioning plate 411 and a connecting plate 412 that fits against the welding table 1. The connecting plate 412 is fixedly connected to the welding table 1. The position of the push-pull plate 41 can be adjusted forward and backward to adjust the distance between the positioning device 4 and the baffle 5 according to the rim width. During adjustment, loosen the bolt 9, move the push-pull plate 41 forward and backward appropriately, and then lock the bolt 9 after adjustment.

[0023] The welding joint tightening mechanism 3 includes a telescopic cylinder 31 connected to an air pump. The telescopic cylinder 31 is fixedly connected to the middle of the support plate 102. The telescopic cylinder 31 has a telescopic rod 32, and a connecting plate 33 is fixedly connected to the bottom of the telescopic rod 32. A shock-absorbing cylinder 34 is provided at the connection between the connecting plate 33 and the telescopic rod 32. A tightening wheel 35 is provided at each of the left and right ends of the bottom of the connecting plate 33. The shock-absorbing cylinder 34 can alleviate the impact force generated when the tightening wheel 35 contacts the wheel rim.

[0024] When using this rim welding joint tightening device, the open rim 10 to be welded is placed vertically between the positioning device 4 and the baffle 5, with the rim joint positioned between the two tightening wheels 35. The positioning device 4 is adjusted, and the push-pull plate 41 is moved forward to clamp the rim between the baffle 5 and the push-pull plate 41. After adjustment, the push-pull plate 41 is fixed to the welding table 1 with bolts 9. Then, the telescopic cylinder 31 is activated, the telescopic rod 32 moves downward, and the connecting plate 33 drives the two tightening wheels 35 to move downward (e.g., ...). Figure 6 As shown), during the downward movement of the two tightening wheels 35, they will press inward at the two side interfaces of the rim 10, pulling the interfaces of the rim 10 inward until the two openings are tightly joined together (as shown). Figure 7 As shown), the interface is welded. After welding, the telescopic cylinder 31 is activated, which drives the tightening wheel 35 to return to its original position. The welded rim is then loosened and removed for processing of the next open rim.

[0025] The tightening wheel 35 is connected to the connecting lug 36 via a short shaft 37, which allows the tightening wheel 35 to rotate. This prevents the tightening wheel 35 from generating excessive friction with the rim 10 when it presses inward against the opening of the rim 10, thus avoiding unnecessary deformation of the rim 10.

[0026] The specific implementation of this utility model has been described in detail above, but it is only an example. This utility model is not limited to the specific implementation cases described above, and equivalent modifications to this utility model are also within the protection scope of this utility model.
