Problems solved by technology

[0002] With the development of society and the advancement of technology, users have high requirements for precision, noise and vibration, and it is difficult for ordinary lathes to meet the above new requirements.
In the past, the advanced systems used on ordinary lathes were stepping motors, cam levers or ordinary screw mechanisms, and their feeding accuracy could only reach 2um at the highest, and some even failed to reach 2um. Such a structure is increasingly unable to meet the requirements of users, but the cost of directly replacing the CNC lathe is very high. If a new CNC drive system is used to replace the traditional drive system, the above problems will be solved.

Abstract

The invention relates to a novel servo positioning device applicable to an engine lathe. The novel servo positioning device comprises a servo motor which is connected with a ball screw through an elastic coupling; the end, close to the elastic coupling, of the ball screw is mounted on a bearing seat through an angular contact ball bearing; the bearing seat is mounted in a connecting base fixed on a lathe bed; the other end of the ball screw is connected with a screw nut seat which is connected with a workbench dragging plate through countersunk bolts, and an encoder is mounted on the servo motor. The novel servo positioning device is convenient for encoding, high in rotation speed, fast in feeding, simple in structure, convenient to maintain and high in positioning accuracy.

Description

technical field [0001] The invention relates to the field of automatic precision machining, in particular to a novel servo positioning device suitable for common lathes. Background technique [0002] With the development of society and the advancement of technology, users have very high requirements for precision, noise and vibration, and it is difficult for ordinary lathes to meet the above new requirements. In the past, the advanced systems used on ordinary lathes were stepping motors, cam levers or ordinary screw mechanisms, and their feeding accuracy could only reach 2um at the highest, and some even failed to reach 2um. Such a structure is increasingly unable to meet the requirements of users, but the cost of directly replacing the CNC lathe is very high. If a new CNC drive system is used to replace the traditional drive system, the above problems will be solved. Contents of the invention [0003] The purpose of the present invention is to overcome the problems exist...
