Abstract

The invention discloses an electric main shaft tool mechanism for performance testing. The electric main shaft tool mechanism comprises a fixed clamping plate, a movable clamping plate and a movable clamping plate sliding mechanism which adjusts distance between the two clamping plates. The fixed clamping plate and / or the movable clamping plate are provided with clamping chucks for fixing a testedelectric main shaft. The clamping chuck comprises a chuck body, a claw, a claw driving mechanism which drives the claw to perform radial motion, and a positioning pin which is connected with the endof the claw. The claw driving mechanism comprises an inner gear ring which is embedded into the chuck body, and a screwing mechanism which drives the inner gear ring to perform circumferential movement along the chuck body. The inner gear ring is in threaded connection with the back part of the claw. The screwing mechanism drives the inner gear ring to rotate, and drives the claw to perform radialmotion along the chuck body through a screw thread. The tool mechanism further comprises a sensor installing belt. The sensor installing belt is provided with a plurality of electric main shaft temperature sensors and a plurality of sound level sensors. The electric main shaft tool mechanism can fix the electric main shafts with different lengths and different diameters and furthermore has advantages of wide application range, simple structure and high convenience in mounting.

Description

technical field [0001] The invention relates to the technical field of equipment testing, in particular to an electric spindle tooling mechanism for performance testing. Background technique [0002] The electric spindle is the core component of the high-speed CNC machine tool, and its performance directly determines the high-speed machining performance of the machine tool. The electric spindle rotates at high speed during the working process, which requires high acceleration and deceleration performance, which puts higher requirements on the heat dissipation, lubrication and precision control of the electric spindle. At the same time, during the high-speed operation of the electric spindle, due to the heating of the electric spindle bearing and the built-in motor, it will cause a series of problems such as thermal deformation, vibration, and noise of the electric spindle, which will affect the machining accuracy. Therefore, it is necessary to test the performance of the el...
