Description

Technical Field

[0001] The utility model relates to the technical field of flange production, in particular to a multi-station tooling for one-time welding of flanges. Background Art

[0002] Flange, also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two equipments, such as reducer flange.

[0003] Any connection parts that are bolted and closed around two planes are generally called "flanges", such as the connection of ventilation ducts, which can be called "flange parts". However, this connection is only a part of a device, such as the connection between a flange and a water pump, so it is not appropriate to call the water pump a "flange part". Smaller ones such as valves can be called "flange parts". Flanges are usually welded on the circumference of the end of the pipe to connect the pipe, valve and shaft together.

[0004] During the existing flange production process, the flange needs to be welded to the production accessories. The existing welding equipment needs to position and clamp the flange, but the existing clamping device does not have the function of angle adjustment. Therefore, when the user needs to weld in multiple places, the flange must be removed repeatedly, which brings great trouble to the user. Summary of the invention

[0005] To this end, the utility model provides a multi-station tooling for one-time welding of flanges. The user places the flange on the top of the base and welds the flange and processed accessories through the welding groove to solve the problem that the existing welding equipment needs to position and clamp the flange, but the existing clamping device does not have the function of angle adjustment. Therefore, when the user needs to weld in multiple places, the flange must be repeatedly removed, which brings great trouble to the user.

[0007] Two first fixing blocks, each of which has two first bearings disposed therein;

[0008] Two first fixed shafts, the two first fixed shafts are respectively arranged at the inner sides of the two first fixed blocks, and the two first fixed shafts are respectively movably connected to the two first fixed blocks via rolling bearings;

[0009] A bridge plate, wherein the bridge plate is fixedly connected between the two first fixed shafts;

[0010] A positioning mechanism is provided on the top of the bridge plate.

[0011] Preferably, the positioning mechanism comprises a second fixed shaft, which is disposed on the top of the bridge plate and is movably connected to the second fixed shaft via a rolling bearing.

[0012] Preferably, a second fixed block is fixedly connected to the top of the second fixed shaft, and a base is fixedly connected to the top of the second fixed block.

[0013] Preferably, a plurality of welding grooves are provided on the top of the base, and the plurality of welding grooves are evenly distributed around the center of the base.

[0014] Preferably, both sides of the plurality of welding grooves are fixedly connected with limit pins.

[0038] The user embeds the multiple holes corresponding to the flange into the outside of the multiple positioning pins 14. At this time, the flange is located on the top of the multiple support blocks 10. After the placement is completed, the multiple pressure plates 11 are rotated so that the multiple pressure plates 11 are located on the top of the flange, so that the multiple pressure plates 11 perform extrusion positioning work on the flange.
