Numerical control lathe for precision machining

Abstract

The invention discloses a numerical control lathe for precision machining, and belongs to the field of numerical control lathes. A main motor drives a main shaft body to rotate after speed reduction through a motor belt wheel, a synchronous belt and a main shaft belt wheel, stepless speed change is achieved, heat generated by movement of the main shaft body promotes ammonium chloride powder to be heated and decomposed into hydrogen chloride gas and ammonia gas, an elastic balloon is driven to expand to extrude a flexible heat absorption pad to be bent and expands to drive a magnetic rod to be close to a magnetic plate, an elastic telescopic pipe and the magnetic plate are driven to extend out through repulsive force, and a deformation memory spring is heated to extend to drive the magnetic plate to be unfolded, so that sufficient adsorption of scrap iron is achieved, and the scrap iron is prevented from interfering with rotation of the main shaft body; and along with cooling of cooling liquid in a bent hose and decomposition and heat absorption of the ammonium chloride powder, the temperature in a main shaft box is reduced, so that the influence of too high temperature on lubrication in the main shaft box body is avoided, interference on rotation of the main shaft body is reduced, and the precision is improved.

Description

technical field [0001] The invention relates to the field of numerically controlled lathes, and more specifically relates to a precision-machined numerically controlled lathe. Background technique [0002] CNC lathe is an automatic lathe equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, and decode them, express them in coded numbers, and input them into CNC lathes through information carriers. After calculation and processing, the numerical control device sends out various control signals to control the movement of the lathe, and automatically process the parts according to the shape and size required by the drawing. It is a flexible and high-efficiency automatic lathe. [0003] In the prior art, during the machining process of the CNC lathe, it is easy to cause splashed iron filings to enter the spindle box and affect the internal spindle transmission, resulting in a decrease in the ...
