Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an anti-springback flange welding fixture. Background Technology

[0002] During the manufacturing process of car door panels, it is necessary to fold the edges of the door panels to make them look smooth. Then, the folded edges of the door panels are welded and fixed to the inner panels by installing the inner panels.

[0003] After welding, due to the thermal expansion and contraction characteristics of the material and the problem of material springback after heating, the flanging process often fails to meet the predetermined standards after welding. However, pre-bending with a mold requires a long time for debugging due to the welding process, which is extremely wasteful of time and material costs. Utility Model Content

[0004] The purpose of this invention is to provide an anti-springback flange welding fixture to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A springback-resistant flange welding fixture includes a base plate. Multiple lifting devices are mounted on the top of the base plate, each with a blocking positioning block on its top. A through hole, which is threaded, is located at the center of the top of the base plate. The bottom end of a support rod is threaded into the through hole. A rolling device is fitted onto the top of the support rod. The rolling device includes a disc, a first bearing, a second bearing, a sliding sleeve, a top rod, a telescopic rod, and a roller. The first bearing is fitted onto the top of the support rod. A mounting hole is located at the center of the disc, which is fitted onto the first bearing. The sliding sleeve is slidably mounted on the support rod. The second bearing is fitted onto the sliding sleeve. One end of the telescopic rod is fixedly mounted on the bottom of the disc, and the other end is fixedly connected to the top of the top rod. The roller is rotatably mounted on the bottom of the top rod.

[0007] By adopting the above technical solution, the cooperation between the telescopic rod and the disc can control the position of the top rod on the top of the base plate. The height of the disc can be controlled by the screw connection at the bottom of the support rod. Thus, the roller can be manually driven to roll and flip the disc through appropriate height adjustment and control. Before welding, the flipping angle is rolled once, and the springback amount is preset to avoid the flipping warping after welding.

[0008] In a further embodiment, the telescopic rod includes a first square tube and a second square tube, the first square tube being fixedly installed at the bottom of the disc, and one end of the second square tube being slidably installed inside the first square tube.

[0009] In a further embodiment, a protruding limiting block is provided at one end of the second square tube located inside the first square tube, the protruding limiting block being used to limit the maximum sliding distance of the second square tube.

[0010] In a further embodiment, a limit plate is provided on one side of the roller.

[0011] In a further embodiment, a handwheel is provided at the top of the support rod.

[0012] In a further embodiment, the outer ring of the second bearing is provided with a connecting rod, the other end of which is fixedly connected to the bottom of the disk.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The position of the top rod on the top of the base plate can be controlled by the cooperation of the telescopic rod and the disc. The height of the disc can be controlled by the screw connection at the bottom of the support rod. Thus, the roller can be manually driven to roll and flip the disc through the appropriate height adjustment and control. Before welding, the flipping angle is rolled once and the springback amount is preset to avoid the flipping warping after welding. Attached Figure Description

[0020] Example 1:

[0021] like Figures 1-2 As shown, an anti-springback flange welding fixture includes a base plate 1. Multiple lifting devices 2 are mounted on the top of the base plate 1. Each lifting device 2 has a blocking positioning block 4 on its top. A through hole, which is threaded, is located at the center of the top of the base plate 1. The bottom end of a support rod 3 is threaded into the through hole. A rolling device 5 is fitted onto the top of the support rod 3. The rolling device 5 includes a disc 51, a first bearing 52, a second bearing 53, a sliding sleeve 54, a top rod 55, a telescopic rod 56, and a roller 57. The first bearing 52 is fitted onto the top of the support rod 3. A mounting hole is provided at the center of the disc 51, which is fitted onto the first bearing 52. The sliding sleeve 54 is slidably mounted on the support rod 3, and the second bearing 53 is fitted onto the sliding sleeve 54. One end of the telescopic rod 56 is fixedly installed at the bottom of the disc 51, and the other end of the telescopic rod 56 is fixedly connected to the top of the top rod 55. The roller 57 is rotatably installed at the bottom of the top rod 55. The telescopic rod 56 includes a first square tube and a second square tube. The first square tube is fixedly installed at the bottom of the disc 51, and one end of the second square tube is slidably installed inside the first square tube. A protruding limiting block is provided at the end of the second square tube inside the first square tube. The protruding limiting block is used to limit the maximum sliding distance of the second square tube. A limiting plate is provided on one side of the roller 57. A handwheel is provided at the top of the support rod 3. The handwheel is used to better rotate the support rod and adjust the height of the disc. A connecting rod is provided on the outer ring of the second bearing 53. The other end of the connecting rod is fixedly connected to the bottom of the disc 51.

[0022] Specific implementation process: The position of the top rod on the top of the base plate can be controlled by the cooperation of the telescopic rod and the disc. The height of the disc can be controlled by the screw connection at the bottom of the support rod. In this way, the roller can be manually driven to roll and flip the plate by appropriate height adjustment and control. Before welding, the flipping angle is rolled once and the springback amount is preset to avoid the flipping plate warping after welding. When using, the telescopic rod needs to be pulled to the approximate position so that the roller is just above the flipping edge. Then, the height is adjusted by the support rod 3 so that the roller presses down on the flipping edge. Then, the side baffle of the explosion is attached to the edge of the door panel. In this way, when pushing the roller to roll, only the centripetal force of the telescopic rod is needed to avoid the problem of the roller dislodging.

[0023] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
