Embodiment Construction

[0043] see Figure 1-8 , the present invention provides a comprehensive loading method for the reliability test of a CNC cylindrical grinding machine: the workpiece shaft is installed on the head frame of the grinding machine to simulate the workpiece to be ground, and the cylinders 4, 18, 25, 28 are used as force load application devices, The brake 7, 33 is used as the torque load applying device to simulate the stress state of the grinding wheel shaft of the grinding machine and the workpiece to be ground in the actual grinding process. Use the miniature load sensor to collect the applied force load in real time, use the indirect measurement method to obtain the torque signal, transmit the collected signal to the control system of the loading device for data processing, and finally feed back to each load control device, including the output The electric signal acts on the electric proportional valve to control the movement of the cylinders 4, 18, 25, 28, and acts on the magn...

Abstract

The invention relates to a comprehensive loading method and device for a reliability test of a numerically controlled cylindrical grinder. The workpiece shaft is installed on the head frame of the grinder to simulate the workpiece to be ground, and the force applied by four cylinders and two magnetic powder brakes are used. The torque comprehensively simulates the force state of the grinding wheel shaft and the workpiece to be ground during the actual grinding process, and applies loads to the grinding wheel shaft and the workpiece shaft at the same time, collects and feeds back the load signal in real time, and performs closed-loop control on the applied loads. The present invention can accurately simulate the stress state of the CNC grinding machine during actual processing, provides experimental equipment and test methods for verifying the reliability of the CNC grinding machine, provides a technical basis for improving the reliability of the grinding machine, and can adapt to different types of machines Cylindrical grinder.

Description

technical field [0001] The invention relates to a comprehensive loading method and a loading device for a reliability test of a numerically controlled cylindrical grinder. Background technique [0002] CNC machine tools are the basic equipment in the machinery industry. They have the characteristics of large usage and wide application range, and are the basic means of advanced manufacturing technology. However, the generally low reliability severely restricts the development of domestic CNC machine tools. [0003] In order to improve the reliability of CNC machine tools, the domestic CNC machine tool field has carried out research on a variety of machine tool loading devices, in order to use the loading device to simulate the actual working conditions of CNC machine tools, and to understand the stress, deformation and potential of each part of the equipment under various working conditions. Record and evaluate potential failures, find weak links and make continuous improvem...
