Abstract

The invention relates to a three-directional static rigidity synchronous testing system for a machine tool, and belongs to the technical field of static rigidity detection of the machine tool. The system comprises a load measuring subsystem, a three-directional stressing device, a displacement measuring subsystem and a data processor. The input end of the three-directional stressing device and the input end of the displacement measuring subsystem are connected with a main shaft of the machine tool, the output end of the three-directional stressing device is connected with the input end of the load measuring subsystem, and the output end of the displacement measuring subsystem and the output end of the load measuring subsystem are connected with the input end of the data processor. The testing system can apply load which is at certain angles with the X-axis, the Y-axis and the Z-axis of a machine tool coordinate system, and can measure continuously changing data of the load and deformation of the machine tool along three directions at the same time. After the data are processed by data processing programs, a continuously changing curve of nine Kig components in a 3*3 order static rigidity matrix can be obtained.

Description

technical field [0001] The invention belongs to the technical field of static stiffness detection of machine tools, and in particular relates to a three-way static stiffness synchronous testing system of a machine tool under the condition of simulated loading in the working space of a complete machine tool, and also relates to a static stiffness testing method based on the testing system. Background technique [0002] The static stiffness of the machine tool has a great influence on the machining accuracy and surface quality of the machine tool, and it is one of the important indicators for evaluating the performance of the machine tool. Through the test of the static stiffness of the machine tool, the weak link in the performance of the machine tool can be identified, and then the machining process plan of the machine tool can be formulated in a targeted manner, or the machine tool can be optimized to improve the machining accuracy of the machine tool. [0003] At present, ...
