Lathe work method for thin-walled parts of middle-small diameter

Abstract

The invention discloses a method for turning middle and small thin-wall element, wherein the invention uses auxiliary clamper on general turning machine, first based on the outer diameter of element, produces a slim sheath with same diameter and middle slim as auxiliary clamper, machines the blank of object element, then puts the draw-in gear into the inner hole of slim sheath, puts them together into three-claw positioning clamping disc of turning machine, clamping and machining roughly and finely, and since the invention uses slim sheath as auxiliary clamper, the long-disc claw can obtain uniform dispersed clamping force on the surface of object element, to reduce unit clamping force, reduce vibration and deformation or the like. And the invention improves efficiency via transferring thin-wall element on three-claw automatic positioning clamping disc.

Description

Technical field [0001] The invention relates to the field of mechanical processing, and relates to a turning processing method, in particular to a turning processing method of small and medium diameter thin-walled parts. Background technique [0002] There are many parts on the fan, especially most of the parts on the fan rotor are thin-walled parts with relatively thin wall thickness, such as various bearings, bushings, etc. Due to the relatively thin wall thickness of these parts, the cutting heat generated in the turning process is relatively concentrated, and it is not easy to lose. Moreover, the parts are prone to deformation and vibration under the action of clamping force, which directly affect the processed parts The dimensional accuracy and surface roughness of the parts are mainly manifested in the dimensional accuracy and shape and dimensional accuracy of the processed parts, and the surface roughness of the parts is difficult to meet the design requirements of the dra...

AI Technical Summary

Problems solved by technology

Due to the relatively thin wall thickness of these parts, the cutting heat generated during the turning process is relatively concentrated and difficult to dissipate, and the parts are easily deformed and vibrated under the action of clamping force, which directly affects the processed parts. The dimensional accuracy and surface roughness are mainly reflected in the fact that the dimensional accuracy and shape and dimension accuracy of the processed parts are difficult to guarantee, and the surface roughness of the parts is also difficult to meet the design requirements of the drawings.
