Machine tool spindle trial run platform capable of simulating working conditions

Abstract

The invention provides a machine tool spindle trial run platform capable of simulating working conditions. A front spindle fixing support and a rear spindle fixing support are arranged on a working table and used for supporting the front portion and the rear portion of a spindle to be tested correspondingly. A displacement information acquisition mechanism used for acquiring displacement information of a check rod and an angle / speed measurement information acquisition mechanism used for acquiring rotation information of a spindle holder are arranged on the working table and correspond to the check rod at the front end of the spindle to be tested and the spindle holder. The front end and the rear end of the spindle to be tested are both provided with acceleration sensors and temperature sensors, and the acceleration sensors and the temperature sensors are used for acquiring vibration information and temperature information of the spindle to be tested in the running process. A driving motor used for driving the spindle to be tested to rotate, a motor position adjustment mechanism used for adjusting the horizontal position of the driving motor and a force sensor module used for acquiring the magnitude of tensile force of the driving motor during movement are arranged below the working table. A motor sheave of the driving motor is connected with a spindle sheave at the rear end ofthe spindle to be tested through a transmission belt. The machine tool spindle trial run platform capable of simulating the working conditions is a machine tool spindle dynamic performance test platform capable of realizing omni-directional system integration.
