Problems solved by technology

During the processing of rotor blade tenon, the technological reference position of the blade is generally special. At the same time, due to the different processing positions, the blade needs to be loaded and unloaded multiple times, which affects the processing accuracy and processing efficiency. The labor intensity of the operator is high, and it is easy to cause the processing size of the part to be out of tolerance.

Abstract

The invention discloses a datum conversion device for machining a rotor vane joint. The datum conversion device comprises a base plate, a square box limiting clamping block I, a standard square box, avane locating ball, a vane head locating mechanism, a side face tightly-pressing mechanism, a top tightly-pressing mechanism, a vane tightly-pressing screw, a vane tail locating mechanism, a square box limiting clamping block II, an overturning pressing plate I and an overturning pressing plate II. By means of the datum conversion device, the machining difficulty of the rotor vane joint can be lowered; machining stability and production efficiency are improved; the labor intensity of operators is lowered; and machining quality problems due to errors caused by multiple times of clamping are reduced.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular provides a reference conversion device for processing rotor blade tenons. Background technique [0002] As an important part of turbomachinery such as aero-engines and gas turbines, blades have complex shapes and extremely high machining accuracy. During the processing of rotor blade tenon, the technological reference position of the blade is generally special. At the same time, due to the different processing positions, the blade needs to be loaded and unloaded multiple times, which affects the processing accuracy and processing efficiency. The labor intensity of the operator is high, and it is easy to cause the processing size of the part to be out of tolerance. Contents of the invention [0003] The purpose of the present invention is to provide a reference conversion device for processing the tenons of rotor blades without changing the existing machine tool. When chang...
