Problems solved by technology

The first one needs to consume a lot of manpower, material resources and financial resources
The second kind of reliability test of rolling functional parts of CNC lathe by computer can greatly reduce the cost and save time, but the reliability of the product will be greatly reduced, because there will be considerable uncertainty and sudden changes in the actual operation of the equipment. situation, these are computer simulation test equipment can not do

Abstract

The invention discloses a reliability test device for a rolling functional part of a numerically controlled lathe. The reliability test device comprises an axial force loading unit, a radial force loading unit, a hydraulic pump station, a console and an inclined lathe body, the axial force loading unit and the radial force loading unit are arranged on the inclined bed body in parallel; the hydraulic pump station and the console are arranged beside the inclined bed body; a first moving pair and a first workbench are arranged on the axial force loading unit, and the first workbench can slide on the inclined bed body through the first moving pair; the radial force loading unit is provided with a second moving pair and a second working table, and the second working table can slide on the inclined bed body through the second moving pair; the first workbench and the second workbench are connected through a dowel bar and move in parallel. According to the technical scheme, the axial force, the radial force and the rotating speed in the loading cutting process are simulated at the same time; high-frequency or low-frequency vibration generated in the real turning tool cutting process can be effectively simulated; simulation of actual working conditions of the rolling function part of the numerical control lathe and reliability test are realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing equipment and methods, and in particular relates to a reliability testing device and method for rolling functional parts of a numerically controlled lathe. Background technique [0002] The CNC lathe is a very typical electromechanical-hydraulic integration system, which contains a large number of components. In order to improve its reliability, not only the reliability test of the whole machine, but also the reliability test of its components is mandatory. As the key components of CNC lathes, the rolling functional parts have very prominent problems in terms of accuracy and reliability, and new technologies are urgently needed to solve them. There is still a considerable gap between our country and foreign countries in the research on the reliability of rolling functional parts. To study its accuracy and reliability, the research and development of test benches is very important. Roll...
