Problems solved by technology
For small machine tools, this measurement method can basically meet the accuracy measurement requirements because of the small diameter of the screw rod and it is easy to push manually after assembly. However, this method is not feasible for large machine tools because the screw rod is thick. 1. The workbench is heavy, and it cannot be measured manually because it cannot be pushed manually. Even if it is pushed barely, the tightness cannot be felt. In addition, the limitation of the measurement position of the dial gauge makes it impossible to accurately reflect the measured data

The invention relates to measurement equipment, in particular to measurement method and device of the comprehensive assembly accuracy for a numerical control machine. In the measurement method, a screw rod is driven by a servo motor to drive a workbench to move, workbench position variable quantity is collected in real time through a fixed time interval in the process, and comprehensive assembly accuracy of the screw rod and a guide rail isreflected through the position variable quantity and a drive moment value. The measurement device comprises a measured screw rod, a measured guide rail, a measured nut seat, the servo motor which is connected with the measured screw rod and a control system of the servo motor, wherein the control system comprises a motor drive module, a data collection module, a data analysis module and a database module. The measurement system and the measurement method are particularly suitable for measuring the comprehensive assembly accuracy of the guide rail, the screw rod and the nut seat of a large-scale numerical control machine with a thick screw rod and have the advantages of strong universality and high accuracy; and the system can be the control system of the numerical control machine, is beneficial to cost saving and enhances the working efficiency.
Description
Technical field [0001] The invention relates to a measuring device, in particular to a comprehensive assembly accuracy measuring device for a numerical control machine tool and a measuring method thereof. Background technique [0002] At present, the comprehensive installation accuracy measurement method of the screw, guide rail and nut seat (workbench) on the printed circuit board CNC machine tool is generally: after the overall assembly is completed, manually push the workbench back and forth to feel the tightness of each position during the pushing process , And then cooperate with the value displayed by the dial indicator to evaluate the comprehensive assembly accuracy of the guide rail, the screw rod and the nut seat. For small machine tools, this method of measurement can basically meet the accuracy measurement requirements because of the small diameter of the screw rod and easy push after assembly. However, this method is not feasible for large machine tools because the sc...
