Automatic high-speed precision numerical control machine tool for cutting spherical surface

Abstract

The invention provides an automatic high-speed precision numerical control machine tool for cutting a spherical surface, which is provided with a base, wherein a main shaft device is arranged on one side at the upper part of the base; a saddle dragging plate which does linear reciprocating motion along the axis of the main shaft of the main shaft device is arranged at the upper part of the base, which is positioned at the same side of the main shaft device; a direct-driving type torque motor rotary table device is arranged on the saddle dragging plate; a rotary axis of the direct-driving typetorque motor rotary table device is absolutely intersected with the rotary axis of the main shaft device; the upper end of the direct-driving type torque motor rotary table device is connected with arotary saddle device and drives the rotary saddle device to do rotary reciprocating motion around the axis of the direct-driving type torque motor rotary table device; a tool rest dragging plate device which does linear reciprocating motion along the direction perpendicular to the axis of the main shaft of the main shaft device is arranged at the upper end of the rotary saddle device; and linear motion of the tool rest dragging plate device and rotary motion of the rotary saddle device form cutting motion for workpieces, so that the workpieces clamped at the front end of the main shaft deviceis cut to form a regular spherical shape.

Description

technical field [0001] The invention relates to the technical field of machine tool manufacturing, in particular to a high-speed precision automatic numerical control machine tool for spherical cutting. Background technique [0002] In industries such as sanitary ware and automobiles, high-precision spherical parts that require a contour of 2 μm and a smoothness of 0.4 μm are often encountered. According to the traditional processing conditions in the past, such parts often need to be roughed by ordinary cars----whirlwind milling Ball (or ordinary CNC car ball)----CNC whirlwind grinding spherical surface----Manual polishing and other processes, even if the process control is very strict, the defective rate and scrap rate are relatively high, and due to the processing It is cumbersome and the work efficiency is not high. There are two main reasons: one is that the CNC lathe processes the spherical shape according to the principle of CNC interpolation. To form the required sh...
