Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and specifically to a flange machining tooling. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as gearbox flanges. To facilitate flange disassembly, an outer flange plate is often installed on the outer edge of the flange. After machining the outer contour of the flange, further precision machining (such as the outer diameter and inner bore) is required, which conventional lathe clamping and fixing devices, such as three-jaw chucks, are insufficient for.

[0003] Therefore, developing a tooling that can effectively clamp and fix flanges for processing is of great practical significance. Utility Model Content

[0004] Due to the aforementioned defects in the existing technology, this utility model provides a tooling that can effectively clamp and fix flanges for processing, specifically a flange processing tooling, to solve the problem that conventional lathe clamping and fixing devices, i.e., three-jaw clamps, are difficult to use for clamping and fixing flanges.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flange processing fixture, wherein the flange includes a circular flange body, a flange through hole is opened in the center of the flange body, and multiple flange outer flanges are fixed on the outer edge of the flange body and evenly arranged around the center circumference of the flange body. A flange outer flange protrusion is provided on one side of the flange outer flange. The flange processing fixture includes a fixture base plate.

[0007] The tooling base plate is provided with a tooling center fixing column that matches the through hole in the flange;

[0008] The tooling base plate is also provided with multiple flange fixing devices for fixing the outer flange of the flange, and each device corresponds to one of the outer flanges of the flange.

[0009] This utility model provides a flange processing fixture that uses the central through hole of the flange as a positioning part, and at the same time, it is used in conjunction with a flange fixing device to fix the outer flange plate to prevent it from flying off during rotation. This ensures that the flange is clamped and fixed for subsequent processing, and it has great application prospects.

[0010] As a preferred technical solution:

[0011] As described above, the flange processing fixture has three outer flange plates.

[0012] There are three flange fixing devices, and the three flange fixing devices are evenly arranged around the central fixing column of the tooling.

[0013] As described above, a flange processing fixture includes a flange fixing device comprising a flange pressure plate.

[0014] The flange plate is fixed to the tooling base plate by plate fixing bolts.

[0015] As described above, a flange processing fixture has a screw hole on its base plate that matches the pressure plate fixing bolt, and the pressure plate fixing bolt is threadedly connected to the screw hole.

[0016] As described above, in a flange processing fixture, when the flange is assembled on the flange processing fixture, the flange pressure plate abuts against the protruding side of the outer flange plate.

[0017] As described above, a flange processing fixture is further provided with a limit pin fixed on the base plate of the fixture;

[0018] When the flange is assembled onto the flange machining fixture, the limiting pin abuts against the other side of the flange outer flange protrusion. The limiting pin serves to limit rotation and prevent the product from rotating along with it.

[0019] As described above, in a flange processing fixture, the flange pressure plate has a through hole, the screw end of the pressure plate fixing bolt passes through the through hole and is threadedly connected to the base plate of the fixture, and the nut end of the pressure plate fixing bolt limits the flange pressure plate.

[0020] The flange processing fixture described above has a circular base plate.

[0021] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0022] Compared with the prior art, the above-mentioned utility model has the following advantages or beneficial effects:
