Clamping device for gas turbine bearing seats

Abstract

The invention discloses a clamping device for gas turbine bearing seats. The clamping device comprises a positioning base, a positioning shaft, a conic sliding block, guiding blocks, positioning blocks, an adjusting nut, pressing plates and support piles, a plurality of radially extending grooves are formed in one side of the positioning base, the positioning shaft is mounted on the positioning base in an inserted manner, the conic sliding block is mounted on the positioning shaft in a sleeving manner, the adjusting nut is mounted at the other end of the positioning shaft, the guiding blocks and the positioning blocks are slidably arranged in the grooves and are connected, end faces of one ends, opposite to the conic sliding block, of the positioning blocks match with an inner wall of a gas turbine bearing seat, and the pressing plates are mounted on flanges of an outer wall of the gas turbine bearing seat in a pressing manner and are fixed on the positioning base through fixing bolts.By the aid of the clamping device, positioned clamping of gas turbine bearing seats different in specifications and dimensions can be realized, and production cost of the gas turbine bearing seat canbe reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a clamping device for a bearing seat of a gas turbine. Background technique [0002] Gas turbine bearing housing is an important part of gas turbine. The structure of the gas turbine bearing seat is a two-end flange type rotary body, which has the characteristics of thin wall thickness, poor rigidity and high machining accuracy. At present, in order to prevent the gas turbine bearing seat from being damaged during the process of clamping the gas turbine bearing seat, special tooling is usually designed to precisely match the inner wall surface of the gas turbine bearing seat to ensure that the gas turbine bearing seat is not damaged and will not move. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Since the gas turbine requires a variety of gas turbine bearing...

AI Technical Summary

Problems solved by technology

[0004] Since gas turbines require a variety of gas turbine bearing housings of different specifications and sizes, it is necessary to design multiple sets of special tooling to complete the positioning and clamping of gas turbine bearing housings of different specifications and sizes, which makes the processing cost of gas turbine bearing housings higher.
