Description

Positioning fixture for hot forging three-way flange processing Technical Field The utility model relates to the technical field of machine manufacturing, in particular to a positioning fixture for hot forging of a three-way flange. Background In general, when processing a three-way flange, blank materials are ensured to be stable, clamped and cut by a cutter. The existing commonly used three-way flange machining process comprises the steps of firstly flattening and punching one end face, then taking down a workpiece, turning the workpiece by 90 degrees, re-clamping the workpiece to machine a second plane, and then taking down the workpiece again, turning the workpiece by 90 degrees, and re-clamping the workpiece to machine a last plane. On one hand, the perpendicularity of a plane after common clamping processing can only be judged by experience, and the precision is low, on the other hand, the workpiece is required to be clamped again for many times without positioning tooling processing, so that the processing efficiency and the processing stability are affected, on the other hand, the processed product is easy to have quality problems, and the reworking and scrapping of the unqualified product can increase the production cost. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a positioning fixture for hot forging of a three-way flange. In order to achieve the purpose, the hot forging three-way flange processing positioning fixture comprises a three-way flange, a pressure head arranged at one end of the three-way flange and a positioning seat arranged at the other end of the three-way flange, wherein a connecting hole is formed in one end, connected with the pressure head, of the three-way flange, the pressure head is provided with a connecting part, the three-way flange is detachably connected with the pressure head through the matching of the connecting part and the connecting hole, a cushion block is arranged between the positioning seat and the three-way flange, a baffle plate is arranged on the positioning seat, and the baffle plate is provided with a plurality of protruding parts. Further, the first blind hole has been seted up to the surface of connecting portion, the second blind hole has been seted up on the pore wall of connecting hole, the position of seting up of second blind hole with the position of seting up of first blind hole is corresponding, be equipped with elastic component and locating part in the second blind hole, the one end of elastic component with the pore wall of second blind hole is connected, the other end of elastic component with the locating part is connected, at least part the locating part is via the second blind hole exposes to the external world and can stretch into in the first blind hole. Further, the limiting piece is of a spherical structure, and the elastic piece is a spring. Further, the elastic piece is a columnar structure made of silica gel or rubber materials. Further, the number of the first blind holes is multiple, and the number of the second blind holes corresponds to the number of the first blind holes.
