Offset correction device for motor rectification blade

Abstract

The invention discloses an offset correction device for a motor rectification blade and belongs to the field of motor blades. The device comprises a base and a press machine arranged on the base, anda head end fixed base and a tail end fixed base are arranged on two sides of the press machine on the base respectively. A stepless positioning base is arranged between the bottom side of the press machine and the base, and the stepless positioning base comprises a sliding base arranged on the base and connected with the base in a sliding mode and a movable base plate arranged between the slidingbase and the press machine and movably connected with the sliding base. The offset correction device can ensure that the motor rectification blade designs an offset correction requirement to the hilt,and greatly increase the convenience of adjusting the position of an output end of the press machine to ensure that the output end of the press machine can reach to all positions of the motor rectification blade. The device is convenient to use and remarkable in economical benefit, and the demand of large quantity, short period and fast rhythm of an existing motor rectification blade can be met.

Description

technical field [0001] The invention relates to the field of engine blades, in particular to a device for correcting deflection of engine rectifying blades. Background technique [0002] The existing aero-engine low-pressure rectifying blades are generally composed of square tenons, convergent blades, and double-cylindrical rotor crowns. run. Therefore, in the manufacture of low-pressure rectifying blades of the engine and subsequent assembly of components, it must be ensured that the finished products of the low-pressure rectifying blades fully meet the final use requirements. Because it is an integral aviation aluminum alloy part, and its own shape characteristics in the processing process cause its actual deformation to be extremely large, and it often has some offsets of up to 8mm, so a correction offset device must be designed , so that the low-pressure rectifying blade reaches the final design state. If the actual deformation is assembled on the engine without corre...

AI Technical Summary

Problems solved by technology

There are three main problems in this method: 1. The positioning state of the parts is unstable during calibration, and the force point on the surface of the airfoil cannot be accurately found, which will easily cause uneven force on the surface of the airfoil, so that the correction of the offset area cannot achieve the desired effect ; 2. Accurate force correction cannot be realized in the state of stepless adjustment. Stepless adjustment means that any force of any size can be applied at any position on the surface of the airfoil without being affected by space restrictions; 3. The correction efficiency is low. Stage batches, large cycles, and tight nodes cannot meet the needs of the site
