Description

Technical Field

[0002] Flange, also known as flange, is just a general term. It usually refers to a disc-shaped metal body with several fixing holes around it for connecting other things.

[0003] The patent with publication number CN218487622U discloses a flange welding device for flange production, including a warehouse body, an adjustment component is arranged inside the warehouse body, a welding component is arranged on the inner top wall of the warehouse body, the adjustment component includes a partition fixedly mounted on the inner peripheral wall of the warehouse body, a servo motor fixedly mounted on the front side wall of the inner cavity of the warehouse body, the output shaft of the servo motor is fixedly mounted with a threaded rod through a coupling, the outer surface of the threaded rod is threadedly connected with two moving plates, the tops of the two moving plates are embedded with electric push rods, the tops of the two moving plates are fixedly mounted with fixed warehouses, the output ends of the two electric push rods are fixedly mounted with moving rods, and slide rails are fixedly mounted between the front and rear side walls of the inner cavity of the two fixed warehouses. The flange welding device for flange production has the advantage of conveniently fixing large and small flanges by being provided with an adjustment component.

[0004] The existing flange welding device for flange production usually fixes one side of the flange and uses a welding assembly to weld the other side. As a result, during use, when the user needs to weld the other side of the flange, that is, the side where the fixing assembly is located, the flange needs to be disassembled again, rotated and then re-fixed. This not only takes a lot of time, but also during the turning process, since the welding head often stops working not long ago, its surface temperature is high. When the user's hand accidentally touches the welding head, there is a risk of burns. Therefore, this process also has certain safety hazards. Utility Model Content

[0034] In the embodiment of the utility model, when the flange needs to be rotated, the second servo motor 14 is started, and the second servo motor 14 drives the first rotating rod 15 to rotate, and drives the first bevel gear 16 to rotate. Since the first bevel gear 16 and the second bevel gear 18 are meshed with each other, and the second bevel gear 18 is fixed to the second rotating rod 17, the second servo motor 14 can be started to drive the second rotating rod 17 to rotate, and the working plate 19 can be driven to rotate under the rotation of the second rotating rod 17, which is convenient for adjusting the angle of the top flange.
