High-speed numerically-controlled machine tool used for machining precision part

Abstract

The invention discloses a high-speed numerically-controlled machine tool used for machining a precision part. The high-speed numerically-controlled machine tool comprises a machine head provided with a cutter, a first steel ring sleeve, a second steel ring sleeve, a third steel ring sleeve and a fourth steel ring sleeve. The front end of an x-direction lead screw located in an x-direction main bearing mechanism is embedded into the first steel ring sleeve, an x-direction motor output shaft is embedded into the second steel ring sleeve, and the two ends of a first buffer spring are fixedly connected with the end face of the first steel ring sleeve and the end face of the second steel ring sleeve respectively. Each steel ring sleeve comprises a basic ring base and a fixed half ring fixed on the end face of the basic ring. One end of each elastic half ring is fixed at the one end of each fixed half ring, and a gap is reserved between the other end of each elastic half ring and the other end of each fixed half ring. The other end of each elastic half ring and the other end of each fixed half ring are connected with a bolt used for adjusting the gap. The situations that due to the fact that eccentricity and error happen on the motor output shaft and the lead screw, damage and deformation are caused are prevented, and product precision and efficiency are improved.

Description

technical field [0001] The invention relates to a numerical control machine tool, in particular to a high-speed numerical control machine tool used for machining precision parts. Background technique [0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, screw taps, dies and knurling tools for CNC machine tools can also be used for corresponding processing on the lathe. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces, and are the most widely used machine tools in machinery manufacturing and repair factories. [0003] Existing CNC machine tools have weak bearing capacity, low machining accuracy and product forming efficiency. How to design a CNC machine tool with strong bearing capacity, high precision, high speed, high machining accuracy and high product forming rate has become the direction of efforts of those skilled in the art. .
