Abstract

The invention provides a clamp for flattening and processing a high-speed power turbine support ring sleeve for a gas turbine, relates to a clamp for flattening the turbine support ring sleeve and processing an inner circle and solves the problem that no clamp suitable for flattening of the high-speed power turbine support ring sleeve of an existing gas turbine and processing of the inner circle exists, and accordingly the manufacture is difficult. A right clamp body and a left clamp body are arranged on a support, a side wall of the right clamp body is provided with a semi-circular arc groove, a side wall of the left clamp body is provided with a second semi-circular arc groove corresponding to the first semi-circular arc groove, a workpiece to be processed is arranged in a limiting groove which is formed by the first semi-circular arc groove and the second semi-circular arc groove and matched with the workpiece to be processed, the right clamp body is connected with the left clamp body through a positioning block and a connecting piece, on end of a screw jack is connected with the support, and the other end of the screw jack is connected with an outer wall of the right clamp body. The clamp is used for flattening and processing the high-speed power turbine support ring sleeve of the gas turbine.

Description

technical field [0001] The invention relates to a fixture used for flattening a sleeve for a turbine support ring and processing an inner circle. Background technique [0002] A certain type of gas turbine adopts many new technologies, new materials, and new structures in the design, resulting in complex structural shapes of parts and high requirements for machining accuracy and surface roughness. Since the speed of the high-pressure power turbine part reaches 5500rpm, high requirements are placed on the stability of the bearing. It is necessary to add a pre-tightening force to the outer ring of the bearing to ensure the stability of the bearing when it rotates. This pre-tightening force is provided by a belt The elliptical sleeve with high elastic potential energy is provided. Due to the high temperature, the material used for the elliptical sleeve is 8Cr2Ni4WA, which belongs to high-strength alloy carburizing steel. The inner circle and the outer circle are processed into...
