Integrated tool system for integral blisk blade intake and exhaust edge and blade root grinding

Abstract

The invention relates to an integrated type tool system for polishing an overall blade disc blade air inlet edge, an air outlet edge and a blade root, and belongs to polishing tool systems. A fast switching device and a servo motor are coaxially installed on the front face and the back face of a substrate respectively. A buffering device, a supporting device, an idle pulley device and the fast switching device are installed on the front face of the substrate. The fast switching device is connected with an abrasive belt polishing driving wheel or a polishing head tool system. One end of a rotary platform is installed on the back face of the substrate through a rotary platform connecting plate. The integrated type tool system has the advantages that the structure is novel, the problem that the overall blade disc blade air inlet edge, the air outlet edge and a blade root part are hard to polish due to the limitation of the space is solved, the abrasive belt polishing method and the polishing head polishing method can be selected through the fast switching device according to the different polishing objects of the blade air inlet edge, the blade air outlet edge and the blade root, one servo motor can drive two sets of polishing tools, the tool integration performance is good, the size and weight of the tool system are reduced, the subsidiary time is shortened, and the polishing quality and the polishing efficiency are improved.

Description

technical field [0001] The invention belongs to a tool system for grinding and polishing, in particular to an integrated tool system for grinding and polishing of integral blisk blades. Background technique [0002] Blades are key parts of aero-engines, steam turbines and other equipment, and their machining accuracy directly affects the performance of the whole machine. However, blade parts generally have complex structures and poor rigidity, and work in high temperature, high pressure, and strong corrosive environments for a long time, and are subjected to alternating loads. Therefore, they are required to have good mechanical properties, thermal deformation resistance, corrosion resistance, and high precision and surface quality. Blade processing has always been one of the difficult problems in the manufacturing process of aero-engines and steam turbines. In particular, the grinding and polishing of the blisk, the key component of the next-generation aero-engine, is mor...

AI Technical Summary

Problems solved by technology

In particular, the grinding and polishing of the blisk, the key component of the next-generation aero-engine, is more difficult than the traditional blade grinding and polishing.

[0003] For a long time, the grinding and polishing of blades has been done manually by workers, which has low production efficiency, high work intensity, high requirements on the technical level of workers, and difficulty in ensuring precision.

Especially for the grinding and polishing of the inlet and exhaust edges of the overall blisk blade and the blade root, due to the limited space, the grinding and polishing operation is difficult, and the consistency of manual grinding and polishing is difficult to ensure. It is necessary to develop an automatic device to improve the grinding and polishing efficiency and ensure the grinding and polishing consistency of quality
