Abstract

The invention discloses a servo feeding system reliability testing device and method. The problem that a reliability testing device and method do not have the simulation numerical control machine tooldouble screw synchronous drive servo feeding system loading function is solved. The device comprises a double screw synchronous drive servo feeding system, a loading system, a detection system and acontrol system; the double screw synchronous drive servo feeding system is installed on a foundation through a tool body platform, the loading system is installed on the tool body platform through a servo manifold block support and a servo oil cylinder support, the loading system is connected with a working table installed on the tool body platform through a floating connector, and a first displacement sensor, a second displacement sensor, two pressure sensors, a first proximity sensor, a second proximity sensor and a laser interferometer in the detection system are installed on the tool bodyplatform and the foundation at the left side of the tool body platform; the control system is installed on the foundation at the upper right of the tool body platform through an operation desk. The invention further provides the testing method.

Description

technical field [0001] The invention relates to a test device in the fields of precision manufacturing technology and industrial automation control, more precisely, the invention relates to a reliability test device and a test method of a servo feed system. Background technique [0002] As an important part of CNC machine tools, the feed system has a direct impact on the positioning accuracy, stability and processing quality of the machine tool. The servo feed system composed of servo motor driven ball screw as the main transmission component is the most widely used in high-end CNC machine tools. The traditional linear feed system of CNC machine tools mainly uses a single ball screw. The driving structure of the single screw is unstable, and it is easy to generate large translation and torsion during operation, which affects the accuracy of the feed system. With the development of machine tools in the direction of high speed, high precision and high stability, higher requir...
