Dynamic loading five-axis numerical control machine tool cradle type swing table reliability test system

Abstract

The invention discloses a dynamic loading five-axis numerical control machine tool cradle type swing table reliability test system which comprises a cradle type swing table, a dynamic loading part, a simulation test part, an environment simulation part and a state monitoring part. The cradle type swing table, the dynamic loading part, the simulation test part, the environment simulation part and the state monitoring part are arranged on the horizontal iron; the dynamic loading component realizes real-time multi-angle dynamic loading of the simulation test component, the environment simulation component and the state monitoring component on the cradle type swing table; the simulation test component can be installed at any position of the rotating table, so that the force and torque combined loading of the cradle type swing table can be realized at the same time; through the matching design of the contact part of the simulation test part and the loading rod device, the real-time transmission of the load is ensured; dynamic signals such as vibration, temperature and rotating speed are monitored in real time; according to the technical scheme, the test requirements of cradle type swing tables in different models and different working temperature environments can be met.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of numerical control processing equipment, is applicable to a cradle-type five-axis numerical control machine tool, and specifically relates to a reliability test system for a dynamically loaded cradle-type swing table of a five-axis numerical control machine tool. Background technique [0002] CNC machine tools are essential key equipment in modern manufacturing systems and modern manufacturing equipment with high-tech content. The quality of CNC machine tools is an important indicator to measure the degree of industrial modernization of a country, which affects the country's manufacturing capacity and comprehensive national strength.

Problems solved by technology

[0004] In the prior art, there is only a static stiffness test device for the cradle-type swing table, which can only carry out axial and tangential static loading on the rotary table, but cannot realize torque loading, and cannot realize multi-axis linkage working state However, in the actual use of five-axis CNC machine tools, the cradle-type swing table and the rotary table are in a multi-axis linkage compound motion state, and the working conditions simulated by the existing test equipment have great limitations; In addition, the cradle-type table will also bear the torque brought by the workpiece processing, and the existing test equipment obviously cannot simulate this type of load; Due to the load caused by the load, the existing experimental device obviously failed to simulate the actual working state including the temperature environment and coolant spray, and could not detect and analyze the motion state and functional state of the cradle table in real time, and it was difficult to meet the current requirements. Requirements for a comprehensive test of the reliability of the cradle table
