The invention belongs to the technical field of mechanical
machining equipment reliability tests, and relates to a
system for testing the reliability of a transverse working table of a
traverse-head contour shaping
machine for simulating dynamic and static
cutting loads. The defect that the loading reliability test problem of a transverse working table of a
traverse-head contour shaping
machine ina simulated actual working condition cannot be realized by an existing reliability test device in the prior art can be overcome. The
system comprises a X-direction loading part, a Y-direction loadingpart, a Z-direction loading part and a loading auxiliary part. The X-direction loading part comprises a rack, a gear, a
torque sensor and a
hydraulic pump. The Y-direction loading part comprises twosets of Y-direction piezoelectric
ceramic loading devices. One set of the Y-direction piezoelectric
ceramic loading device is installed at the right upper corner position of a to-be-tested
workbench.The other set of the Y-direction piezoelectric
ceramic loading device is installed at the right lower corner position of the to-be-tested
workbench. The Z-direction loading part comprises a Z-direction piezoelectric ceramic
actuator, a Z-direction tension and
pressure sensor, and a Z-direction linear bearing. The auxiliary loading
workbench of the loading auxiliary part is fixed on the to-be-tested workbench.
