Abstract

The invention relates to a machining center lubricity test system and an optimization method and belongs to the field of testing of machining center lubrication systems. Thermosensitive parts of a spindle system and a feed system are identified by thermal imaging testing of the spindle system and the feed system, and temperature sensors are mounted at the thermosensitive parts. A test system of a machining center lubrication system is set up; the lubrication amount is adjusted by adjusting a lubrication time interval of a machining center; the spindle system and the feed system of the machining center move continuously in different lubrication amount states; and simultaneously, temperature data at the thermosensitive parts is acquired. The lubrication amount of the spindle system and the feed system of the machining center is optimized based on temperature rises of the thermosensitive parts. The invention provides the test system and the optimization method for optimizing the lubrication amount of the machining center lubrication system; the problem of unreasonable lubrication amount setting of the machining center lubrication system at present is solved; the movement performance of a machine tool can be improved; the use cost of the machine tool is lowered; and the pollution of lubricating oil is reduced.

Description

technical field [0001] The invention relates to the testing field of a machining center lubrication system, in particular to a machining center lubrication performance testing system and an optimization method. Background technique [0002] The testing and optimization of the machining center lubrication system is a difficult problem in the machine tool industry. Unreasonable lubrication supply will affect the smoothness of motion and the temperature rise of the machine tool, which will cause large thermal errors and affect the accuracy of the machine tool. At present, the lubrication system of machining centers generally adopts the method of regular and quantitative supply, and the setting of lubrication interval is generally based on experience, but in fact, the amount of lubrication should be different for machining centers with different specifications and different loads. The optimal lubrication interval The time needs to be determined after real-time monitoring and te...
