Machining tool used for thin-wall barrel type part

Abstract

The invention discloses a machining tool, in particular to a machining tool used for a thin-wall barrel type part and belongs to the technical field of machining technology, assembly, design and manufacturing. By means of the machining tool used for the thin-wall barrel type part, large machining errors in the machining process of the thin-wall part due to clamping reasons can be effectively avoided. The machining tool comprises a base frame and clamping support components, and the base frame is sleeved with the clamping support components in an expansible and contractible mode in the radial direction; the thin-wall barrel type part is fixed onto the machining tool in an expansible mode through the clamping support components, and the machining tool is installed on machining equipment for the thin-wall barrel type part in a clamped mode through the base frame.

Description

technical field [0001] The invention relates to a processing tool, in particular to a processing tool for thin-walled cylindrical parts, and belongs to the technical field of mechanical processing technology assembly design and manufacture. Background technique [0002] It is generally believed that in shell parts, sleeve parts, ring parts, disc parts, and shaft parts, when the ratio of the wall thickness of the part to the radius of curvature of the inner diameter is less than 1:20, it is called a thin-walled part. [0003] In actual production, when processing various types of thin-walled parts, it is often encountered that the parts are easily deformed during the processing. To analyze the internal and external causes of deformation of the machined parts, so that when processing such thin-walled parts, how to prevent their deformation, so as to meet the requirements of the parts drawings, the exploration of the processing methods to meet the various technical indicators a...

AI Technical Summary

Problems solved by technology

Second, because the workpiece is thin, cutting heat will cause thermal deformation of the workpiece, making it difficult to control the size of the workpiece

Third, under the action of cutting force, especially radial cutting force, it is easy to generate vibration and deformation, which affects the dimensional accuracy, shape, position accuracy and surface roughness of the workpiece

[0009] However, due to fixtures or human operations, the main deformations that are likely to be caused are: workpiece deformation due to uneven clamping force, uneven heat dissipation of the workpiece, low positioning accuracy, low coaxiality, and incapable of one-time processing of thin-walled parts. The entire outer surface is machined
