Description

Technical Field

[0001] This utility model relates to the field of vacuum boiler technology, and in particular to a wheel rim interface welding and mating 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 interface welding and mating device, which is achieved through the following technical solution: A wheel rim joint welding and mating device includes an operating table, with a support leg at each of the four corners of the top of the operating table, a support plate on the top of all the support legs, a workpiece clamping mechanism on the operating table, and a mating and tightening mechanism connected to the support plate.

[0004] The workpiece clamping mechanism includes a fixed positioning device located at the front end of the operating table and a movable positioning device located at the rear end of the operating table corresponding to the fixed positioning device. The fixed positioning device includes an "L"-shaped fixing plate, which includes a vertically arranged positioning plate and a connecting plate that fits against the operating table. The connecting plate is fixedly connected to the operating table.

[0005] The movable positioning device includes a positioning seat, the bottom of which is fixedly connected to the operating table. A groove is provided at the rear of the positioning seat, and a telescopic cylinder is horizontally fixedly connected to the groove. The telescopic cylinder is provided with a telescopic rod, which passes through the positioning seat. A linear bearing is provided on the positioning seat corresponding to the telescopic rod, and the telescopic rod is connected to the linear bearing.

[0006] A linear bearing 2 is provided on each of the left and right sides of the linear bearing 1. Each linear bearing 2 is connected to a linear shaft. A push plate is fixedly connected to the top of all the linear shafts and the telescopic rod 1. A shock-absorbing pad is provided at the connection between the push plate and the linear shaft and the telescopic rod 1.

[0007] The tightening mechanism includes a telescopic cylinder 2, which is fixedly connected to the middle of the support plate. The telescopic cylinder 2 is provided with a telescopic rod 2, and a connecting plate 1 is fixedly connected to the bottom of the telescopic rod 2. A shock-absorbing cylinder is provided at the connection between the connecting plate 1 and the telescopic rod 2. A tightening wheel is provided at each of the left and right ends of the bottom of the connecting plate 1.

[0008] As a preferred embodiment, the operating table is provided with a support leg at each of the four corners of its bottom.

[0009] As a preferred embodiment, the push plate is rectangular in shape.

[0010] As a preferred embodiment, the shock-absorbing pad is in the shape of a "[" and is fixedly connected to the push plate.

[0011] As a preferred embodiment, the shock-absorbing pad is made of rubber.

[0012] 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.

[0013] As a preferred embodiment, the connecting plate is provided with several vertical waist holes 1, and the operating table is provided with waist holes 2 corresponding to the waist holes. Bolts pass through waist holes 1 and waist holes 2 to fix the connecting plate to the operating table.

[0014] Compared with existing technologies, the advantages of this invention are: it enables automatic alignment at the rim interface, and during the alignment process, the rim is subjected to uniform force, preventing unnecessary deformation. This improves efficiency, saves time and labor, and reduces the defect rate.

[0015] When using this rim joint welding and mating device, the open rim to be welded is placed vertically between the fixed positioning device and the movable positioning device, with the opening positioned between the two tightening wheels. Telescopic cylinder one is activated, causing telescopic rod one and the two linear axes to move forward, driving the push plate forward and clamping the rim between the push plate and the fixed plate. Then, telescopic cylinder two is activated, causing telescopic rod two to move downwards. Connecting plate one drives the two tightening wheels downwards. During the downward movement of the two tightening wheels, they press inwards on both sides of the rim opening, pulling the opening inwards until the two openings are joined together, thus welding the joint. After welding is completed, telescopic cylinder one and telescopic cylinder two are activated, causing the push plate and tightening wheels to return to their original positions. The welded rim is then released and removed for processing the next open rim.

[0016] 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.

The connecting plate 412 is fixedly connected to the operating table 1 by bolts. The connecting plate 412 has several vertically oriented slots 7, and the operating table 1 has slots 8 corresponding to the slots 7. Bolts 9 pass through the slots 7 and slots 8 to fix the connecting plate 412 to the operating table 1. The position of the fixing plate 41 can be adjusted back and forth to adjust the distance between the fixed positioning device 4 and the movable positioning device 5 according to the rim width. During adjustment, the bolts 9 are loosened, and the fixing plate 41 is moved back and forth appropriately. After adjustment, the bolts 9 are locked.

[0020] The movable positioning device 5 includes a positioning seat 51, the bottom of which is fixedly connected to the operating table 1. A groove 52 is provided at the rear of the positioning seat 51. A telescopic cylinder 6 is horizontally fixedly connected to the groove 52. The telescopic cylinder 6 is provided with a telescopic rod 62, which passes through the positioning seat 51. A linear bearing 63 is provided on the positioning seat 51 at the location corresponding to the telescopic rod 62. The telescopic rod 62 is connected to the linear bearing 63.

[0021] A second linear bearing 64 is provided on each of the left and right sides of the first linear bearing 63. Each second linear bearing 64 is connected to a linear shaft 65. A push plate 66 is fixedly connected to the top of all the linear shafts 65 and the first telescopic rod 62. A shock-absorbing pad 67 is provided at the connection between the push plate 66 and the linear shafts 65 and the first telescopic rod 62. The shock-absorbing pad 67 can reduce the impact force generated when the push plate 66 contacts the wheel rim. When the first telescopic cylinder 6 is activated, the first telescopic rod 62 moves linearly along the first linear bearing 63, and the linear shaft 65 moves linearly along the second linear bearing 64, thereby driving the push plate 66 to move and achieve the fixed clamping of the wheel rim.

[0022] The tightening mechanism 3 includes a second telescopic cylinder 31, which is fixedly connected to the middle of the support plate 102. The second telescopic cylinder 31 has a second telescopic rod 32, the bottom of which is fixedly connected to a first connecting plate 33. A shock-absorbing cylinder 34 is provided at the connection point between the first connecting plate 33 and the second telescopic rod 32. A tightening wheel 35 is provided at each of the left and right ends of the bottom of the first connecting plate 33. The shock-absorbing cylinder 34 helps to mitigate the impact force generated when the tightening wheel 35 contacts the wheel rim.

[0028] When using this rim joint welding and mating device, the open rim 10 to be welded is vertically placed between the fixed positioning device 4 and the movable positioning device 5, with the opening positioned between the two tensioning wheels 35. The telescopic cylinder 6 is activated, causing the telescopic rod 62 and the two linear shafts 65 to move forward, driving the push plate 66 forward and clamping the rim between the push plate 66 and the fixed plate 41. Then, the telescopic cylinder 31 is activated, causing the telescopic rod 32 to move downward, and the connecting plate 33 drives the two tensioning 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 on both sides of the opening of the rim 10, pulling the opening of the rim 10 inward until the two openings are joined together (as shown). Figure 7 As shown), the interface is welded. After welding, telescopic cylinder 6 and telescopic cylinder 31 are activated, driving push plate 66 and tightening wheel 35 to return to their positions. The welded rim is then loosened and removed for processing of the next open rim.

[0029] 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.

[0030] Telescopic cylinder 6 and telescopic cylinder 31 are connected to the cylinder, and their strokes are preset according to the specifications of the wheel rim 10.
