Abstract

The invention provides a rotary milling fixture device for machining a guide vane of an air compressor, which can be used to solve the problems of poor generality, poor vane machining rigidity and machining size instability existing in the traditional guide vane clamping mechanism. The rotary milling fixture device is characterized by comprising a big-head-end three-jaw chuck and a small-head-end three-jaw chuck, wherein the big-head-end three-jaw chuck is connected with a main driving disk of a machine tool by a first transition disk, the small-head-head three-jaw chuck is connected with a tip of the machine tool by a second transition disk, a big head end and a small head end of the guide vane to be machined are respectively positioned and clamped by the big-head-end three-jaw chuck and the-small head-end three-jaw chuck, and a small head end part of the guide vane to be processed is tightly jacked up by the tip of the machine tool.

Description

technical field [0001] The invention relates to the technical field of processing guide vanes of gas turbine compressors, in particular to the technical field of tooling for processing guide vanes of gas turbine compressors using a four-axis or five-axis rotary milling machine tool, specifically a rotary milling fixture for processing guide vanes of gas compressors device. Background technique [0002] Gas turbine compressor guide vanes are usually designed as cylindrical or conical surfaces at both ends, and the middle part is the airfoil profile. Since the airfoil profile is an irregular curved surface, the machining of the airfoil profile usually adopts four-axis or five-axis rotation Milling machine, which requires the guide vane to be clamped on the rotary milling machine by using the cylindrical surface or conical surface at both ends of the guide vane as the positioning and clamping reference. In the existing clamping mechanism, the cylindrical surface or conical sur...
