Portable device for detecting full working condition loading and performances of main shaft

Abstract

The invention belongs to the technical field of machinery testing devices, and relates to a portable device for detecting the full working condition loading and performances of a main shaft. The device comprises a simulation knife handle module, a knife handle clamping module, a loading bearing module, an axial force loading module, a radial force loading module, a detection module and an accessory module. The simulation knife handle module in the knife handle clamping module cooperates with a clamping groove at the upper part of a simulation knife handle. An axial force loading head of the axial force loading module makes contact with the bottom of a bearing shell in the loading bearing module in the loading process to achieve the axial force loading of the main shaft. A radial force piezoelectric ceramic loading rod in the radial force loading module makes contact with a bearing shell side surface to achieve the radial force loading of the main shaft. The device applies a load by integrating a main shaft performance detecting component with a standardized knife handle, achieves the real load of the main shaft of a simulated machine tool in the machining process and obtains the performance testing data, so as to improve the operability and accuracy of the reliability test and the performance test of the main shaft.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing equipment, and relates to a device for testing the spindle of a CNC machine tool, in particular, to a device that can simulate the dynamic cutting force and torque received by the spindle during actual cutting, and perform a loading test and performance test on the spindle. detection device. Background technique [0002] As the key functional component of CNC machine tools, the reliability and comprehensive performance of the spindle have a great influence on the operation status of the entire CNC machine tool. Traditional spindle performance tests often require building a specific test bench in a laboratory environment and installing various detection devices for testing. Although some on-site inspection devices for spindles can detect some items, they are only for no-load inspection or actual workpiece cutting, and cannot simulate the performance inspection of loading under specified...
