Numerical control machine tool and machining method thereof

Abstract

According to the technical scheme, a numerical control machine tool is characterized by comprising a machine tool body, a spindle box, an upper spindle and a lower spindle, the spindle box, the upper spindle and the lower spindle are arranged on the machine tool body, the upper spindle and the lower spindle are the same in structure and are symmetrically arranged, and the upper spindle and the lower spindle are in transmission connection through a first belt; a driving mechanism is installed on the machine tool body, and the driving mechanism comprises a driving motor, a driving wheel, a driven wheel and a second belt, the driving wheel is connected to the output end of the driving motor and is controlled by the driving motor to rotate, the driven wheel is rotationally mounted on the machine tool body through a rotating shaft, and the second belt is wound on the driving wheel, the driven wheel and the lower main shaft; and an adjusting mechanism for automatically adjusting the tension of the second belt is further arranged on the machine tool body. The numerical control machine tool and the machining method thereof have the beneficial effects that the working efficiency is high, transmission is stable, the tensioning force of the transmission belt can be automatically adjusted, meanwhile, cooling is controllable, the cooling effect is good, the working temperature is controllable, and working is stable.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a numerically controlled machine tool and a processing method thereof. Background technique [0002] Machine tools refer to machines that make machines, also known as work machines or tool machines, and are habitually referred to as machine tools; they are generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools; there are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting , as well as casting, forging, welding, stamping, extrusion, etc., but for parts with high precision and fine surface roughness requirements, they generally need to be processed by cutting on the machine tool. Machine tools are in the modernization of the national economy. CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system;...

Problems solved by technology

[0002] Machine tools refer to machines that manufacture machines, also known as machine tools or machine tools, which are customarily referred to as machine tools; generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools; there are many ways to process mechanical parts in modern machinery manufacturing: In addition to cutting , as well as casting, forging, welding, stamping, extrusion, etc., but all parts with higher precision requirements and finer surface roughness requirements generally need to be final processed on machine tools by cutting methods. Machine tools play an important role in the modernization of the national economy CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system; the control system can logically process programs with control codes or other symbolic instructions, and Decoding, represented by coded numbers, is input into the numerical control device through the information carrier; after calculation and processing, the numerical control device sends out various control signals to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing; now The production efficiency of some machine tools is not high, and it is difficult to meet the needs of processing efficiency. There are also CNC machine tools with double spindles for processing, but it is inconvenient to adjust the tension force, and the tension force of the transmission belt cannot be automatically adjusted; at the same time, the existing In order to avoid affecting the nature of the workpiece, the machine tool needs to carry out temperature control in order to avoid affecting the properties of the workpiece. However, the existing temperature control device has poor temperature control effect and cannot meet the cooling and cooling speed requirements and temperature accuracy control, which affects the working efficiency of the machine tool.
