Multihead synchronous or asynchronous carving (drilling) milling numerical control processing equipment

Abstract

The invention discloses multihead synchronous or asynchronous carving (drilling) milling numerical control processing equipment which comprises a portal frame, a lathe bed, a numerical control unit, a transmission system and x-axle, y-axle and z-axle guide rails, wherein the numerical control unit comprises an x-axle drive motor, a y-axle drive motor and a z-axle drive motor which are arranged on the portal frame. The multihead synchronous or asynchronous carving (drilling) milling numerical control processing equipment is characterized in that left and right sides of the portal frame are respectively provided with two y-axle guide rails, and the portal frame is also provided with 2-6 independent synchronous or asynchronous power heads and multiple sets of tools matched with the power heads, a lathe generates a three-dimensional processing figure by using a computer, the computer controls each power head respectively for processing after processing coordinates are input, a corresponding control system is provided with a servo motor or a stepping motor, the power heads move on the three guide rails along the x-axle direction, three points are fixed; and a screw or rack structure is adopted in the transmission system. The multihead synchronous or asynchronous carving (drilling) milling numerical control processing equipment has the advantages of simple structure, low cost, high processing accuracy, good stability, high processing efficiency, wide application range and the like.

Description

technical field [0001] The invention relates to a machine tool in mechanical processing, in particular to a multi-head synchronous or asynchronous engraving (drilling) milling numerical control processing equipment. Background technique [0002] With the continuous development of society, today's machinery industry not only pursues the high precision of mechanical manufacturing in processing and manufacturing, but also reflects in high-speed processing technology. Therefore, CNC machine tools are a common mechanical processing equipment that is widely used. , and the use of CNC milling machines for engraving and milling processing of mechanical products is also a commonly used processing form. It is one of the preferred equipment for mold forming, precision machining, especially large-scale precision machining. Existing general CNC engraving and milling processing equipment is usually installed on the column behind the machine tool by a group of CNC units, or mounted on the ...

AI Technical Summary

Problems solved by technology

[0007] The numerical control engraving and milling machine tool of above open document, in the factory of small-scale processing capacity and small batch production, but all there is common problem in large-scale or mass production: the one, the load-bearing area of ​​equipment is little, rigidity is poor, The operation is unstable. The second is that this type of machine tool only has one CNC unit for processing. Every time a workpiece is processed, it must be stopped to replace the tool. This not only wastes time, but also seriously affects work efficiency. CNC machine tools are relatively expensive, so , how to improve the high efficiency of the equipment under high stability has always been a matter of great concern to the machinery industry
