Universal shot blasting fixture used for shot blasting of root of compressor blade

Abstract

The invention provides a universal shot blasting fixture used for shot blasting of the root of a compressor blade. The universal shot blasting fixture aims at solving the problem of high jig manufacture and maintenance cost due to poor universality of an existing shot blasting fixture of the compressor blade and comprises a base, a positioning and adjusting component and an adjustable blade profile enclasping component, wherein height supports with equal heights are respectively vertically arranged at four corner ends of the base, the positioning and adjusting component is supported on the height supports, the adjustable blade profile enclasping component is arranged on the positioning and adjusting component; the positioning and adjusting component comprises positioning guide blocks and sliding plates, the two positioning guide blocks are arranged on the height supports in parallel along the longitudinal direction and are connected through the two horizontally parallel sliding plates, and the sliding plates can move along the positioning guide blocks to achieve adjustment; and a blade inner arc pressing device and a blade back arc pressing device of the adjustable blade profile enclasping component are respectively oppositely arranged at the horizontal inner sides of the two positioning guide blocks with adjustable angles.

Description

technical field [0001] The invention relates to the field of tooling and fixtures for blade processing, in particular to a general shot-peening fixture used for shot-peening treatment of the blade roots of compressor blades. Background technique [0002] Usually due to the different profiles of different types of compressor blades, the part of the shot peening fixture used for the shot peening of the root of the compressor blade that holds the blade profile is designed according to the outer contour of the different compressor blade profiles. As a result, corresponding shot peening fixtures need to be configured for compressor blades of different profiles. The shot peening fixtures have no versatility, and the manufacturing and maintenance costs of shot peening fixtures are high, which cannot meet the daily production mode of small batches and multiple varieties of blades; and frequent replacement. Shot peening fixtures can also lead to inefficiencies in production. SUMMAR...
