Problems solved by technology

The machine tool is always subjected to multi-directional force under the condition of multi-dimensional movement when it is working. The actual load state of the machine tool cannot be reproduced in fact by single-axis loading, and the reliability test results cannot be guaranteed.
Some machine tool manufacturers at home and abroad have to

Embodiment

[0075] The five-axis linkage machine tool loading test device can carry out follow-up loading on the gantry milling machine, such as Image 6 shown. Fix the parallel loading device 23 on the workbench 20 of the machine tool 24 , adjust the position of the workbench 20 and the pose of the parallel loading device 23 , and connect the interface 1 between the loading mechanism and the spindle with the machine tool spindle 21 .

[0076] During actual loading, first, the industrial control computer 11 issues a mechanism initialization command to enable and initialize the mechanism motion controller 9, motor servo driver 8, linear motor 6 and signal compensation and processing device 10, and check and confirm the state of the parallel loading mechanism; after that Start the machine tool spindle 21 and make the machine tool move along the specified tool path; under the action of the control system, the parallel loading device performs follow-up loading on the tested machine tool 24 ac...

Abstract

The invention discloses a five-axis linkage loading test device for a machine tool. The device consists of a following loading mechanism mechanical part and a measurement and control system. The following loading mechanism mechanical part applies a load to a spindle through an interface of the spindle of the machine tool. The measurement and control system is used for realizing servo motor control, mechanism motion control, load calculation and signal processing functions of the following loading mechanism mechanical part. The five-axis linkage loading test method for the machine tool comprises the five major steps of: 1, measuring load data; 2, establishing a load spectrum; 3, organizing tool path data; 4, performing hardware solidification of the data; and 5, calibrating and correcting a database. The device and the method are universal and widely applicable to various types of tests in the reliability of the machine tool, and have practical significance and reference value for the research and development of high-performance load simulators in China.

Description

technical field [0001] The invention relates to a five-axis linkage machine tool loading test device and a loading test method, belonging to the technical field of machine tool reliability experiments. Background technique [0002] CNC machine tools are the key equipment of modern machinery manufacturing industry. Currently, China's machine tool consumption ranks first in the world, but the domestic machine tool market still mainly relies on imports for high-end CNC machine tools. One of the main reasons affecting the competitiveness of domestic high-end machine tools is product quality, and one of the most important quality problems of domestic machine tools is product reliability. There is a big gap between most domestic CNC machine tools and foreign advanced machine tools in terms of product reliability. In addition to the basic links such as key components and manufacturing processes, another key factor affecting the reliability of CNC machine tools is the lack of neces...
