Problems solved by technology

For most precision and ultra-precision machining machine tools, a high-performance linear motion system is necessary and critical. Although the use of an appropriate preload method can reduce or even eliminate the static backlash, it cannot eliminate the friction caused by friction. The non-linear motion caused by certain factors, and the non-linear effect of friction caused by linear motion is much greater than the non-linear effect of friction caused by rotating parts, so the linear motion of the table relative to the guide rail in the CNC machine tool becomes the limit feed accuracy main factor of improvement

Abstract

The invention provides a crawler guide rail drive micro feeding servo system and a synchronous control method. The system comprises a work table servo motor A and a crawler guide rail servo motor B, the work table servo motor A drives a ball screw and drives a worktable to do linear motion, the crawler guide rail servo motor B drives a crawler guide rail to move, instantaneous speeds of the two are equal, the directions are same, and it is ensured that the worktable and the crawler guide rail achieve instant synchronizing. Linear motion climbing is thoroughly removed, the novel feeding servo system shows the excellent characteristics, and is used for the modern numerical control equipment industry, and through the extremely low making cost, the extremely high machine tool precision and performance can be obtained.

Description

technical field [0001] The present disclosure relates to the field of mechanical technology, in particular to a crawler guide rail driving micro-feed servo system and a synchronous control method. Background technique [0002] How to achieve accurate, stable and reliable micro-displacement of the worktable or tool during the machining process is one of the key technical bottlenecks for ultra-precision machining. For most precision and ultra-precision machining machine tools, a high-performance linear motion system is necessary and critical. Although the use of an appropriate preload method can reduce or even eliminate the static backlash, it cannot eliminate the friction caused by friction. The non-linear motion caused by certain factors, and the non-linear effect of friction caused by linear motion is much greater than the non-linear effect of friction caused by rotating parts. Therefore, in CNC machine tools, the linear motion of the table relative to the guide rail become...
