AI Technical Summary

Technical Problem

Traditional clamping methods make it difficult to achieve accurate positioning and processing accuracy of standard parts of aircraft engine blades, resulting in the blade profile processing accuracy being unable to meet usage requirements.

Method used

A polygonal clamping groove and support pin structure is adopted to clamp the standard parts through the support seat and pressure plate. The support pin supports the weak position of the leaf profile, and stepless adjustment is achieved through the locking assembly to ensure the stability and precision of the standard parts during the processing.

Benefits of technology

The machining accuracy of blade profiles is improved, positioning difficulties and cutting deformation problems under traditional clamping methods are solved, and the machining accuracy and stability of blade standard parts are ensured.

Abstract

The application discloses an engine stator blade standard part clamping device and a processing method, wherein the clamping device comprises a support seat, a pressing plate and a connecting rod, the connecting rod is used for connecting the support seat and the pressing plate, the first clamping groove and the pressing plate are combined to form a clamping groove, the clamping groove is used for clamping the end of the standard part, and the cross section of the clamping groove is a polygon matched with the cross section profile of the standard part; the clamping device further comprises a first support pin, a second support pin and a locking assembly, the first support pin is linearly slidably connected with the support seat in the length direction, the second support pin is parallel to the first support pin, the second support pin is linearly slidably connected with the support seat in the length direction, and the locking assembly is used for locking the sliding of the first support pin and the second support pin relative to the support seat, so that the first support pin and the second support pin support the convex position of the standard part. The application solves the problem that the machining precision of the standard part blade profile is difficult to meet the use requirement caused by the traditional clamping mode.
