Abstract

The invention discloses a positioning device and method for blade machining. The positioning device comprises an adapter plate, a supporting block, an AB point positioning block, a C point positioningpin, a D point positioning pin and an EF point positioning block. The AB point positioning block, the C point positioning pin, the D point positioning pin and the EF point positioning block are all installed on the supporting block. Moving auxiliary positioning is added, a hinge pressing mechanism is adopted, and the head and the body of the blade are pressed and operated respectively; the positioning device is novel and compact in structure, accurate in positioning, reliable in pressing, fixed in pressing position, convenient in operation, and rigid enough, the blade body is prevented from being scratched; a scheme of directly adopting a blank reference point for positioning when the turbine working blade is used for processing the tenon is realized; the machining auxiliary procedures are reduced, the cost is reduced, the machining period is shortened, the machining efficiency is improved, meanwhile, the utilization rate of the grinding wheel is increased, the design and manufacturing cost is low, the turbine working blade tenon machining requirement is completely met, and meanwhile referential experience is provided for similar problems.

Description

【Technical field】 [0001] The invention belongs to the technical field of manufacturing turbine working blades of aero-engines, and relates to a positioning device and method for blade processing. 【Background technique】 [0002] Turbine working blade is one of the key parts of aero-engine parts. It is composed of tenon, edge plate and airfoil. Tenon tooth processing is an important processing procedure of this part. According to the routine, low-melting point alloy is poured on the blade first, and the point positioning is transformed into After the alloy block is positioned, broaching, milling and grinding are used to process the tenon. After processing, the low-melting point alloy is melted, and pollution must be removed, resulting in high processing costs, low efficiency, and long processing cycles. Turbine working blades of a certain machine refer to figure 1 , the blade body is thicker and rigid enough. In order to reduce costs, improve efficiency, and shorten the proce...
