Problems solved by technology

However, there are many factors affecting the reliability of the motorized spindle as a machining center, and the environmental stress is complex. A single bench test cannot reflect the living environment of the motorized spindle well, and the failure mode obtained is not necessarily the motorized spindle. failure mode, so the bench test is only suitable for the performance test of the electric spindle, not the reliability test

Abstract

The invention discloses a system and a method for testing the reliability of an electric spindle in a machining center. The method comprises the following steps of: 1, establishing the system for testing the reliability of the electric spindle in the machining center; 2, determining test environment and test time; 3, performing a function test on the electric spindle to remove early failures; 4, acquiring the performance parameter of the electric spindle in a stable state and determining a failure criterion; and 5, circularly machining a typical workpiece, monitoring the state and performanceparameter of the electric spindle and judging the failures. The system comprises a temperature sensor, a noise sensor, a force sensor, an eddy current displacement sensor, a vibration sensor, and a control unit connected with the parts. The system has the advantages of simple and compact structure, low cost, simple principle, convenience of operation, high test accuracy and the like.

Description

technical field [0001] The invention mainly relates to the field of processing equipment, in particular to a test method and system for the reliability of an electric spindle of a machining center. Background technique [0002] As the machining center continues to develop towards high speed, high efficiency and super precision, its reliability level has become the main bottleneck restricting the development of the machining center. Through the actual investigation, it is found that the life of the electric spindle is the main factor affecting the reliability of the machining center. Therefore, to improve the reliability of the machining center, it is necessary to improve the life of the electric spindle. [0003] At present, the methods to improve the reliability of the motorized spindle mainly include selecting suitable high-speed bearings, designing reasonable lubrication and cooling systems, and improving the dynamic and thermal characteristics of the motorized spindle fr...
