Reliability test system of heavy-duty CNC vertical lathe

Abstract

The invention discloses a heavy numerical control vertical lathe reliability test system which aims at solving the problems that at present, a heavy numerical control vertical lathe reliability test device can not simulate dynamic cutting force or static cutting force or torque loading. The heavy numerical control vertical lathe reliability test system comprises a balancing weight inertia loading and loading assisting device, an electro-hydraulic servo cutting force loading device and a vertical dynamometer torque loading device. The balancing weight inertia loading and loading assisting device is installed on a rotating working table in a heavy numerical control vertical lathe. A radial electro-hydraulic servo loading device in the electro-hydraulic servo cutting force loading device is installed on the ground around the rotating working table. One end of the radial electro-hydraulic servo loading device makes contact with the circumferential surface of a loading working table. The top end of an axial electro-hydraulic servo loading device is fixedly installed at the bottom end of a sleeper in the heavy numerical control vertical lathe. The bottom end of the axial electro-hydraulic servo loading device makes contact with and is connected with the upper surface of the loading working table. The vertical dynamometer torque loading device is fixedly connected with the center of the loading working table and the center of the rotating working table at the same time.

Description

technical field [0001] The invention relates to a test device applied in the field of reliability of heavy machining equipment, more precisely, the invention relates to a heavy-duty numerical control vertical lathe capable of realizing dynamic and static cutting force and torque loading on the heavy-duty numerical control vertical lathe reliability test system. Background technique [0002] Heavy-duty machine tools are one of the important CNC processing equipment for pillar industries such as national defense, aerospace, transportation and water conservancy engineering. At present, the heavy-duty CNC machine tools developed in China have achieved certain developments in terms of precision, speed, large-scale, heavy and multi-axis linkage. However, due to the characteristics of heavy-duty machine tools and their large workpieces, large load changes, and large strokes, they are easily affected by working conditions and the environment, resulting in frequent failures and seri...
