Ball screw of engraving-milling machine

Abstract

The invention discloses a ball screw of an engraving-milling machine. A thread rod is arranged on a screw body; a shaft sleeve installation position is formed at one end of the thread rod; a machining shaft end is arranged at one end of the shaft sleeve installation position; a screw hole is formed in the machining shaft end; a thread structure is arranged on a surface layer of the thread rod; a nut is arranged on the thread rod; a reverser is arranged on the nut; a flange installation counterbore hole is formed in one end of the nut; a groove is formed in the nut; an inner wall is arranged at one end of the groove; an electrostatic sheet is arranged at one end of the inner wall; a clamping shaft is arranged at a top end of the electrostatic sheet; a hollow layer is arranged at one end of the electrostatic sheet; a plurality of dust absorption holes are formed in a surface layer of the nut; and a ball is arranged between the thread rod and the groove. The ball screw disclosed by the invention is novel in structure, and simple and convenient to operate, and has the characteristics of being high in accuracy, reversible and high in efficiency; the electrostatic sheet and the hollow layer facilitate absorption for dust falling off during working of the engraving-milling machine through the dust absorption holes; and extremely high dustproof efficiency is achieved, and improvement for working precision and quality is benefited.

Description

technical field [0001] The invention relates to a ball screw, in particular to a ball screw of an engraving and milling machine. Background technique [0002] At present, engraving and milling machine (CNC engraving and milling machine) is a kind of CNC machine tool. It is generally considered that the engraving and milling machine is a CNC milling machine that uses small tools, high power, and high-speed spindle motors. The advantage of engraving machine is engraving. If the hardness of the processed material is relatively high, it will appear powerless. The emergence of engraving and milling machines can be said to fill the gap between the two. The engraving and milling machine can not only engrave, but also mill. It is a high-efficiency and high-precision CNC machine tool. The concept of engraving and milling machine was first proposed and realized by Jiatie. The engraving and milling machine has a wide range of applications, and is widely used in the rough and fine m...
