Abstract

The invention provides an interchangeable clamping device for a turbine disk, which includes a base, a base body, a gland part and a positioning tray, a flange shaft is arranged in the base, and the bottom end of the base body is in contact with the flange shaft. The blue shaft is mated and connected, the gland part is locked with the top end surface of the base body, the positioning tray is installed on the lower bottom surface of the base, and the interchangeable clamping device is connected to the working mechanism through the positioning tray. The interchangeable clamping device for the turbine disk of the present invention can realize the high-rigidity clamping of the turbine disk, and can accurately switch the positioning reference between different processing procedures without manual alignment. This clamping device can be used in the combination of wire cutting and form grinding to process the tenon and groove of the turbine disk. Low, easy to promote the application of this composite processing technology.

Description

Technical field[0001]The present invention relates to the field of vortex engines, and more particularly to a interchange clamp device for a turbine disc.Background technique[0002]In the field of turntile engine, in order to meet the high-push ratio and weight loss requirements of the new generation of large conversions, it is designed to be larger, and the integrated double-wing mounting edge structure is designed, and the installation edge and the spoke sheet. Form a large depth of semi-closed thin-walled cavity, the overall structure is extremely complicated.[0003]However, the turbine disc slit is generally processed by forming milling, pulling processing and other processing. In recent years, with the advancement of electric processing technology and super-hard abrasive grinding technology, the combined processing of wire cutting + forming grinding is started to be applied to the trenching processing of the turbine disc. Traditional pull-down or milling, due to large cutting for...
