Abstract

The invention discloses a positioning device and method for blade processing, comprising an adapter plate, a support block, and an AB point positioning block, a C point positioning pin, a D point positioning pin, and an EF point positioning block all installed on the support block. The invention adds moving auxiliary positioning, and adopts a hinge pressing mechanism to press the blade head and blade body and operate them separately; the invention has a novel structure, compactness, accurate positioning, reliable pressing, fixed pressing position, It is convenient, rigid enough, and avoids scratching the blade body. It realizes the scheme of directly adopting wool reference point positioning when machining the tenon of the turbine working blade, which reduces the auxiliary process of processing, reduces the cost, shortens the processing cycle, improves the processing efficiency, and improves the grinding wheel at the same time. Utilization rate, design and manufacturing cost are low, fully meet the processing requirements of turbine working blade tenons, and provide reference experience 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 processin...
