Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a multi-angle flange assembly and adjustment device for a round pipe. Background Art

[0002] In the prior art, it is very difficult to assemble and adjust the multi-angle flange of a round tube component. The reasons are:

[0003] 1. The round tube material itself has deviations, and the center point is difficult to find;

[0004] 2. The cutting accuracy of the intersecting line of the round tube is not high. It is difficult to locate the flange by the outer dimensions of the round tube, and it is even more difficult to locate the flange at multiple angles.

[0005] 3. It is difficult to measure the multi-angle flange of round tubes. Workers usually use lofting cone lines to control it, but the accuracy is not high.

[0006] In view of the above situation, in order to solve the above problems, unless a total station or 3D scanning is used to achieve accuracy, the cost is very high. If a positioning plate is used for adjustment, multiple welding points will appear on the surface of the round tube and the flange, causing damage to the steel surface. The cost of subsequent repair and grinding is high. Or manual positioning is used, but the hand strength is insufficient and there are safety hazards, and it is difficult to position accurately.

[0007] The Chinese authorization announcement number is CN206854927U, and the authorization announcement date is January 9, 2018. It discloses a welding tool for ensuring the center degree of flange and round tube, including a support platform, a bearing seat, a flange mounting plate, a rotating shaft and a tightening device. One end of the support platform is provided with a tightening device, and the other end is provided with a bearing seat. The bearing seat is provided with a flange mounting plate, which is connected to the bearing seat through a rotating shaft, and the flange mounting plate is provided with a flange. The flange is fixedly mounted on the flange mounting plate with a positioning pin and a bolt. The flange mounting plate is provided with an inner support cylinder, which is fixed in the flange by bolts. The inner wall of the round tube on one side in contact with the flange mounting plate is supported by the inner support cylinder, and the round tube on the other side is tightened by the tightening device to realize the follow-up rotation between the round tube and the flange. The utility model has a simple structure and a reasonable design, so that the center of the flange and the center of the inner support of the round tube are located in one place, and the follow-up rotation of the round tube and the flange is realized to ensure the assembly accuracy. The welding can be completed in a single assembly, which improves the welding production efficiency. The drawback of the prior art is that it cannot locate the multi-angle flange, and therefore, it is not suitable for assembling the multi-angle flange of a round pipe. In view of this situation, a solution is urgently needed. Utility Model Content
