Processing equipment and method for wall thickness difference control and deflection correction of slender shaft workpiece

Abstract

The invention discloses processing equipment and a processing method for wall thickness difference control and deviation correction of a slender shaft workpiece. The processing equipment for the wall thickness difference control and the deviation correction of the slender shaft workpiece comprises an automatic centering clamping mechanism, a supporting mechanism, a processing cutter and a cutter guide mechanism, wherein the automatic centering clamping mechanism is used to clamp the slender shaft workpiece from the two ends of the slender shaft workpiece and to allow the slender shaft workpiece to be automatically centered; the supporting mechanism is used to support the slender shaft workpiece from the side wall surface of the slender shaft workpiece; the processing cutter is used to process a central shaft hole of the slender shaft workpiece; and the cutter guide mechanism is used to guide the processing cutter into the central shaft hole of the slender shaft workpiece. The slender shaft workpiece is kept in the preset position all the time; the structural stability of the slender shaft workpiece in a processing procedure is ensured; the slender shaft workpiece is precisely processed on the condition of precise positioning, so that the wall thickness difference control and the deviation correction on the slender shaft workpiece are realized; the processing equipment and the processing method are adapted to the wall thickness difference control and the deviation correction of slender shaft parts of turboprop and turboshaft series engines.

Description

technical field [0001] The invention relates to the technical field of wall thickness difference control and deflection correction of turboprop engine slender shafts, in particular, to a processing device for wall thickness difference control and deflection correction of slender shaft workpieces. In addition, the invention also relates to a processing design method for wall thickness difference control and deflection correction of slender shaft workpieces. Background technique [0002] With the increase of turboprop and turboshaft series engine models and the improvement of performance requirements in recent years, the design and structural features of the power long shaft, the core transmission part, have also changed to the direction of multi-step holes, multi-diameter ranges, and large aspect ratios. , which increases the difficulty of controlling the wall thickness difference. Since the wall thickness difference directly affects the stability of the power long shaft und...
