Abstract

The invention provides an engagement fixture for square steel blade milling, and can solve the problems of long blade manufacturing period and high machining difficulty easily caused by positioning and clamping blades by a traditional engagement fixture. The engagement fixture for square steel blade milling comprises a turntable, and is characterized by further comprising an engagement clamping mechanism and a floating tip mechanism; the engagement clamping mechanism includes two engagement blocks and a lead screw translation structure; the lead screw translation mechanism is mounted on the turntable; the floating tip mechanism is arranged in the center position of the lead screw translation mechanism; and the two engagement blocks are respectively mounted on the lead screw translation mechanism, are positioned on two sides of the floating tip mechanism, and can oppositely or reversely move along the lead screw translation mechanism.

Description

technical field [0001] The invention relates to the field of tooling fixtures for blade processing, in particular to a teething fixture for milling square steel blades. Background technique [0002] With the continuous development of blade design and research technology, the requirements for manufacturing precision of blades are getting higher and higher, and some traditional fixtures and clamping methods can no longer meet the processing accuracy requirements of existing blades. At present, the fixture used in the milling of square steel blades is the LANG brand bite fixture, which is positioned on the inner back radial surface of the blade root, the air outlet side of the blade root, and the axial end surface of the blade root, and is positioned and pressed by the center hole of the blade crown. Therefore, in order to meet the position accuracy requirements of the blade shroud, it is often necessary to increase the process reference plane on the inner back radial plane of ...
