Multi-station continuous grinding device and method for guide vane

Abstract

The invention discloses a multi-station continuous grinding device and method for a guide vane and belongs to the technical field of gas turbine vane machining. The multi-station continuous grinding device for the guide vane comprises a four-shaft linkage slow feeding grinding machine, a rolling wheel, a grinding wheel and a clamp; the rolling wheel is installed on a rolling wheel shaft of the four-shaft linkage slow feeding grinding machine; the grinding wheel is installed on a grinding wheel shaft of the four-shaft linkage slow feeding grinding machine; the clamp is installed on a rotating table of the four-shaft linkage slow feeding grinding machine; the side face of the rolling wheel comprises four grinding areas; the structure of the four grinding areas is the same as the structure of four machining areas of an installing plate of the guide vane; a structure ground by the side face of the rolling wheel and opposite to the concave and convex structure of the side face of the rolling wheel is formed on the side face of the grinding wheel; and the clamp comprises a bottom plate which is provided with an upper installing plate positioning and clamping mechanism, a lower installing plate positioning and clamping mechanism, a vane body tight pressing mechanism, a radial positioning and clamping mechanism and a pot back positioning and clamping mechanism. By means of the device and method, four to-be-machined stations of the guide vane can be subjected to continuous grinding.

Description

technical field [0001] The invention relates to the technical field of gas turbine blade processing, in particular to a multi-station continuous grinding device and method for guide blades. Background technique [0002] With the development of aviation machinery processing industry technology, the requirements for the accuracy of the mounting plate on the multi-connected guide vane are getting higher and higher. In the process of manufacturing aero-engine or gas turbine blades, the mounting plate and blade body of the guide Guaranteed casting without margin. Since the material of the guide vane is high-temperature casting alloy, which is a difficult-to-machine material, the processing performance is poor, resulting in low processing efficiency. The mounting plate of the guide vane is mainly machined to ensure accuracy. Feed grinding is used to machine the mounting plate of the guide vanes. [0003] The mounting plate of the guide vane mainly has four processing areas, such ...
