Heavy-duty CNC gantry boring and milling machine table feed system reliability test bench

Abstract

The invention belongs to the technical field of heavy machining equipment reliability testing and particularly relates to a heavy numerical control plano-boring and milling machine workbench feeding system reliability test bed. The heavy numerical control plano-boring and milling machine workbench feeding system reliability test bed solves the problem that an existing reliability testing device cannot conduct a loading reliability test simulating the actual working conditions on a heavy numerical control plano-boring and milling machine workbench feeding system. The heavy numerical control plano-boring and milling machine workbench feeding system reliability test bed comprises a balancing weight inertia loading and loading auxiliary device part, an X-direction loading part, a Y-direction loading part, a Z-direction loading part and an automatic control part. The X-direction loading part comprises a vibration exciter, a first tension and pressure sensor, an auxiliary loading workbench, a first X-direction loading rod, a second X-direction loading rod and a cover plate. Two sets of identical hydraulic loading devices serve as the Y-direction loading part. The Z-direction loading part comprises an electro-hydraulic servo loading unit. The automatic control part comprises an upper industrial personal computer, a PLC, a vibration exciter controlling instrument, a Y-direction servo controller, a Z-direction servo controller, a servo controller in the moving direction of a workbench and a servo controller in the moving direction of an auxiliary workbench.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of heavy machinery processing equipment, and in particular relates to a reliability testing platform for the feed system of a heavy-duty numerical control gantry boring and milling machine worktable for simulating dynamic and static cutting loads and inertial loads. Background technique [0002] Heavy-duty CNC gantry boring and milling machines are widely used in various mechanical processing departments to process various planes, grooves, gears, etc. Equipped with various milling machine accessories such as universal milling head, round table, and dividing head, the scope of use of the machine tool can be further expanded. Its application range is becoming wider and wider, but due to the characteristics of the heavy-duty CNC gantry boring and milling machine itself and its large workpiece, large load changes, and large strokes, it is easily affected by working conditions and the envir...
