Abstract

The invention relates to a heavy numerical control planing machine mobile workbench reliability test device, belongs to the technical field of heavy mechanical machining equipment reliability test, and overcomes the problem that only the no-load operation test or the field reliability test can be performed on the heavy numerical control planing machine at present. The test stand comprises a counterweight inertial loading part, a loading auxiliary part, an X-direction loading part, a Y-direction loading part, a Z-direction loading part and an automatic control part. X-direction, Y-direction andZ-direction high-frequency cutting force loading on the workbench can be realized by using the piezoelectric ceramic actuator, X-direction static and low-frequency cutting force loading on the workbench can be realized by using the magnetic powder brake and Y-direction and Z-direction static and low-frequency cutting force loading on the workbench can be realized by using the hydraulic servo oilcylinder.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of heavy-duty cutting processing equipment, and in particular relates to a reliability testing device for a mobile workbench of a heavy-duty numerical control gantry planer capable of simulating inertial force, dynamic cutting force and static cutting force. Background technique [0002] Heavy-duty CNC gantry planers are widely used in various mechanical processing departments such as power stations, automobiles, and ships, and are especially suitable for processing extra-large, extra-heavy, and extra-long parts. The heavy-duty CNC planer has the characteristics of large self-weight, large load change, huge inertia, long stroke, etc., which makes it have frequent failures and lower reliability than other ordinary machining equipment. Its reliability problem is serious, and it has become the focus of attention of machine tool manufacturers and users and the bottleneck of the development...
