A CNC double-sided lathe for processing large-diameter thin-walled disk parts

Abstract

The invention discloses a numerical control two-sided lathe for machining large-diameter thin-wall disc parts. The numerical control two-sided lathe comprises a main drive system, two feeding system sets, a lathe body and a servo motor. The main drive system is provided with a main shaft which is of a hollow structure and used for mounting a clamp and connected with the servo motor. The clamp is used for clamping parts to be machined and comprises a clamp body and a pressing plate. The two feeding system sets are symmetrically arranged on the two sides of the main shaft. Each feeding system set comprises an x-direction movement assembly, a z-direction movement assembly and a knife rest. The x-direction movement assembly is arranged on the lathe body in the radial direction of the main shaft. The z-direction movement assembly is arranged on the x-direction movement assembly in the axial direction of the main shaft. The knife rest is arranged on the z-direction movement assembly. The knife rest can move in the x direction and the z direction through the x-direction movement assembly and the z-direction movement assembly. By means of the numerical control two-sided lathe, two-sided synchronous turning of the disc parts can be achieved, normal cutting force born by the parts counteract one another in the machining process, machining deformation of thin-wall parts can be reduced effectively, and machining accuracy is high.

Description

technical field [0001] The invention belongs to the field of thin-wall parts processing equipment, and more specifically relates to a numerically controlled double-sided lathe used for processing large-diameter thin-wall disk parts. Background technique [0002] Thin-walled parts have been increasingly widely used in various industrial sectors due to their material saving, light weight, and compact structure. However, thin-walled parts are weak in strength, poor in rigidity, and easy to deform. , The wall thickness is thin, so it is difficult to ensure the shape and position accuracy and processing quality of the parts during the processing process, which is prone to processing deformation, which seriously affects the processing accuracy of the parts, and it is difficult to clamp and position large-diameter thin-walled disc parts during the processing process Therefore, it is a difficult point in the processing process to solve the positioning and clamping of large-diameter ...

[0002] Thin-walled parts have been increasingly widely used in various industrial sectors due to their material saving, light weight, and compact structure. , The wall thickness is thin, so it is difficult to ensure the shape and position accuracy and processing quality of the part during the processing process, it is easy to produce processing deformation, which seriously affects the processing accuracy of the part, and it is difficult to clamp and position large-diameter thin-walled disc parts during the processing process , so to solve the positioning and clamping of large-diameter thin-walled disc parts, how to reduce the deformation during positioning and clamping, and how to improve its processing quality and quality are a difficult point in the processing process

[0003] Existing large-diameter thin-walled disc parts are mainly processed on one side by ordinary lathes, which process the two sides of the disc part separately through two clampings. High dimensional accuracy and surface roughness requirements, especially the large diameter and thin wall thickness of large-diameter thin-walled disk parts, so it is difficult to guarantee the flatness accuracy requirements and production needs of two planes by using ordinary lathes for single-sided processing, and the parts have large deformation , poor quality, and low processing efficiency
