Numerical control equipment moving precision test device and test method

Abstract

The invention discloses a motion precision testing device for numerical control devices, which comprises a signal conditioning plate connected with a numerical control device, a data collecting card and a programmable computer, wherein level conversion or input-output conversion of pulse signals or feedback signals which are real-time received and outputted by the numerical control device can becarried out by the signal conditioning plate, the data collecting card receives signals input by the signal conditioning plate at real time to convert the signals into computer readable signals and outputs control signals to the numerical control device, and the programmable computer equipped with a storage module stores processing procedures or operating parameters of the numerical control device and then builds up the theoretical trace, controls the data collecting card to output control signals, reads pulse signals or feedback signals of the numerical control device which are inputted by the data collecting card, builds up the real-time operating trace, and displays the theoretical trace and the real-time trace to output. The invention constructs a software and hardware platform according to motion characteristics of the numerical control device, and tests the motion characteristics of the numerical control device via simulated operation, which has high efficiency, simple operationwith various testable contents, wide application scope and high testing precision.

Problems solved by technology

However, with the research and development of advanced CNC systems and drivers, the shortening of production cycles, and the increasing requirements of users for the reliability design of modern CNC machine tools, some traditional CNC system testing methods can only meet the needs of simple functional testing due to their crude design. It cannot fully reflect the performance index of the measured object in detail. For example, after the workpiece is produced by the CNC machine tool on site, the motion accuracy of the CNC machine tool is detected by measuring the workpiece, etc.

These traditional detection methods have the disadvantages of low efficiency, complicated operation, and weak advanced nature. Obviously, they can no longer really meet the needs of the existing CNC system and drive design and production. general direction
