Abstract

The invention provides an improved novel clamp for rotary milling of compressor blades. The clamp has the advantages of stable and reliable clamping, uniform reference and stable rotary milling processing. The clamp comprises a blade root support base, a blade root side surface positioning block and a blade root side surface pressing block are mounted on two sides of the blade root support base respectively, and the blade root support base is mounted at a rotary disc. The clamp is characterized in that a wheel groove is mounted at the upper part of the blade root support base, a padding block is mounted at the bottom of the wheel groove, a rectangular through slot is transversely formed at the bottom of the blade root support base, a slide block is mounted in the rectangular through slot, the slide block is connected with a guide rod through a split pin, and the guide rod vertically penetrates the blade root support base.

Description

(1) Technical field [0001] The invention relates to the field of processing tooling for compressor blades, in particular to an improved new fixture for rotary milling of compressor blades. (2) Background technology [0002] Generally, the rotary milling fixture of the compressor blade is positioned on the side of the blade root intake, such as figure 1 One side of the tooth shape of the blade root is positioned by the tooth-shaped positioning block 1, and the other side is connected with the tooth-shaped pressing block 3 through the rotating mechanism 2, and the blade is pressed with the screw, and the tooth-shaped positioning block 1 and the tooth-shaped pressing block 3 are connected with each other. The tooth shape of the blade root is matched with the top mechanism of the CNC machine tool to complete the clamping work of the rotary milling of the compressor blade. Its clamping is fast and convenient, but it has high requirements on the bottom surface of the blade root, ...
