Problems solved by technology

However, the current high-stress reliability test only applies single-axis loading to CNC machine tools, and it is difficult to apply multi-dimensional loads to multi-axis machine tools.
But in fact, the machine tool is subjected to multi-dimensional forces and moments during cutting, and single-axis loading cannot reproduce the actual working conditions of the machine tool, which greatly reduces the reliability effect

Abstract

A non-contact force loading device for simulating three-axis CNC machine tool processing. The device mainly includes three parts: a loading bar, a loading plate, and a three-translation parallel mechanism; the loading bar is installed on the front end of the three-axis CNC machine tool spindle, and the loading plate is installed On the three-translation parallel mechanism, the three-translation parallel mechanism is installed on the CNC machine tool workbench. The invention tracks the motion of the three-axis CNC machine tool by controlling the three-translational parallel mechanism, so that the loading rod is in the center of the loading disk in real time; by passing currents of different frequencies to the loading disk, forces of different frequencies are applied to the loading rod, thereby simulating the three-axis CNC machine tool The machining process of the machine tool realizes the performance test of the CNC machine tool. The device has a simple and symmetrical structure, is easy to realize modularization, and has low manufacturing cost.

Description

technical field [0001] The invention relates to the field of machine tool reliability tests, in particular to a loading device for simulating three-axis numerical control machine tool processing used in machine tool reliability tests. Background technique [0002] CNC machine tools are high-tech working machines, machines for manufacturing machines, basic equipment for realizing national industrialization, modernization, informatization, and intelligence, and an important guarantee for realizing the strategy of manufacturing a powerful country. For CNC machine tools, its reliability not only refers to the smooth operation of the machine tool itself, but more importantly, it can ensure that qualified products can be processed for a long time, so reliability is an important indicator of CNC machine tools. The reliability of CNC machine tools involves the entire life cycle of CNC machine tools, from the design, manufacture, assembly, installation, commissioning, user use of CNC...
