Abstract

The invention discloses an engine rotor blisk blade-tip curved surface processing device and a method and belongs to the technical field of cold processing in aerotechnics. The device comprises a vertical type numerical control lathe, an electrical main shaft grinding head device, a cooling device, a frequency changer and a clamp. On the premise that functions of the vertical type numerical control lathe are not changed, the electrical main shaft grinding head device and the cooling device are increased, and processing temperatures of an electrical main shaft and a grinding wheel are controlled effectively, so that both turning and curved surface grinding of the vertical type numerical control lathe can be achieved, and the cost is saved. According to the device and the method, a point type grinding method is adopted, complex curved surfaces can be ground accurately and reliably, the production cost of the grinding wheel is low, and a modification method is simple and reliable.

Description

technical field [0001] The invention belongs to the technical field of cold processing in the field of aviation technology, and in particular relates to a device and method for processing an integral blisk blade tip curved surface of an engine rotor. Background technique [0002] At present, the blade tips of the compressor rotor blades in our country are straight or inclined. It is difficult to meet the processing requirements for the curved surface of the compressor rotor blade tip with the existing equipment and current processing methods. Research the use of new equipment or modify existing equipment and develop new processing methods and measurement methods to meet the processing requirements of the blade tip surface. [0003] The compressor rotor is the core component of the engine. In the overall blisk structure (that is, the disc and the blade as a whole), the tip of the blade needs to be processed into a curved surface structure. Therefore, it is very difficult to p...
