Embodiment 1

[0025] CNC system automatic test system, such as figure 1 As shown, it includes a test circuit board 1-1 and a device under test 1-10 connected to the test circuit board 1-1. The test circuit board 1-1 is equipped with a universal input and output interface test circuit, a servo drive and a spindle encoder interface Test circuit and interface test circuit of servo drive and manual encoder;

[0026] The tested device 1-10 is a numerical control system;

[0027] The universal input and output interface test circuit is used to test whether the functions of the universal input and output ports of the device under test 1-10 are normal. The universal input and output interface test circuit includes a universal input interface and a universal output interface directly connected to the universal input interface; The principle is to use the characteristics of the same number of universal input interfaces and universal output interfaces of the tested CNC system to directly connect the univer...

Abstract

The invention relates to a numerical control system and discloses a full-automatic test system of the numerical control system. The full-automatic test system of the numerical control system comprises a test circuit board and a tested device connected with the test circuit board. A general input and output interface test circuit, a servo driver and main shaft encoder interface test circuit and a servo driver and hand-cranking encoder interface test circuit are arranged on the test circuit board. According to the full-automatic test system of the numerical control system, test operation can be performed without special test personnel any more, the test process is fully automatic, all the functions of the numerical control system can be tested, for example, the hardware functions of a numerical control system input and output interface, a servo driver interface, a main shaft encoder interface and a hand-cranking encoder interface are tested; in addition, after the full-automatic test system is matched with special test software operating in the numerical control system, a test result can be automatically displayed, abnormal functions are analyzed, and the most possible fault source is given.

Description

Technical field [0001] The invention relates to a numerical control system, in particular to a fully automatic test system for a numerical control system. Background technique [0002] Numerical control systems have very high requirements for product reliability and stability. The existing numerical control product testing methods are all based on semi-automatic test platforms, that is, special test equipment is used, and when the test equipment is in use, it needs to cooperate The manual operation of the tester realizes the test of the CNC system. The test coverage and accuracy of this method still depend on the quality and proficiency of the testers, resulting in low test efficiency. Therefore, it is necessary to develop a fully automated test equipment that uses no human involvement at all to improve test efficiency, test coverage, and accuracy. Summary of the invention [0003] The purpose of the present invention is to provide a fully automated testing system for a CNC syst...
