Abstract

The invention discloses a precision spindle test run device capable of simulating working conditions. The flow and the mixing ratio of lubricating liquid, the outlet temperature and flow of cooling liquid, the rotating speed and breakdown torque of a test run spindle, the pressure of output gas of a gas source device, the environmental temperature of the test run spindle, the test run time of the test run spindle are set or monitored through a controller or subcontrol units, the parameter values are fed back in time, and the test run of the spindle under the working conditions is simulated; when the monitored values of the controller or the subcontrol units exceed the threshold value or do not conform with the set value, the test run device has the function of giving an alarm and the automatic stopping function. According to the precision spindle test run device, multi-factor real-time monitoring is achieved, the precision spindle test run device capable of simulating the working conditions is built, and therefore it is ensured that the various performances of the precision spindle are optimum on the working conditions.

Description

technical field [0001] The invention relates to the field of performance testing of machine tool spindles, in particular to a precision spindle test device capable of simulating working conditions. Background technique [0002] The spindle is the core functional component of the machine tool, and its performance directly affects the performance of the machine tool. With the development of science and technology, the spindle has formed serialized and standardized functional parts of machine tools. High speed, high precision, high torque and high stability are the basic characteristics of the spindle of precision machine tools. The oil and gas lubrication technology of spindle bearings, precision machining and precision assembly technology, reliability testing and life estimation technology, spindle rotation accuracy testing and error separation technology, and dynamic stiffness online measurement technology reflect the cutting-edge technology of today's high-end spindles.
