Embodiment

[0021]This embodiment is a method of using a tension control to eliminate a double-drive mechanism, which includes the following steps:

[0022]1) Provide a control system including a controller, a first driving member controlled by the controller, and the first drive member drives the same load, the second drive. A pair of racks are provided on the load, wherein one rack is engaged with gear engagement of the gear on the active shaft of the first driving member, and the other rack is engaged with the gear of the slave of the second drive member output shaft. transmission;

[0023]2) Set the tension value PR2903 in the controller;

[0024]3) First initiate the second drive to control the driven shaft in accordance with the preset speed, and the axial load rate of the slave axis of the second drive of the controller real-time and the axial load rate of the first driven When the difference between the two is equal to the setting tension value PR2903, stop the second drive, i.e., the tension co...

Abstract

The invention discloses a method for eliminating the backlash of a dual-drive mechanism by using tension control, the set tension value is greater than a target tension value and less than twice the target tension value, and the target tension value is any one of the drive The corresponding axial load rate when the part-driven load just starts to move; the controller controls the first drive part to drive the load to move, and monitors the axial load rate of the first drive part and the second drive part in real time; When the difference between the axial load rate of the first drive member and the axial load rate of the second drive member is equal to the set tension value, the first drive member is stopped, that is, the tension control is completed, and the backstage is realized. Gap eliminated. The invention can quickly and completely eliminate the backlash of the movement of the dual-drive mechanism, and realize precise motion control without gaps.

Description

[Technical field][0001]The present invention relates to the field of CNC machine tool control technology, and more particularly to a method of eliminating a double-drive mechanism with a tension control.【Background technique】[0002]In the CNC machine tool, there is a situation in which two drivers are used to simultaneously control a single direction due to the large load. Such a mechanism has a large load, usually used the gear rack structure, large back gap, therefore, it is necessary to eliminate its back gap. The method of existing eliminating back gap is to use the gap between the mean or percent or the grating sensor measuring the mechanism, and the amount of the measuring back gap value is input to the controller, allowing the controller to compensate. This method requires manual operation, and it is necessary to measure the measuring error, and there is a measurement error, and it is not possible to reach the motion control of no gap, and the back gap eliminating efficiency i...
