Description

Technical field [0001] The present invention belongs to the technical field of mechanical testing equipment and method, and more particularly to a high frequency simulation loading reliability test apparatus and method. Background technique [0002] The CNC tool holder is a key functional component of a CNC lathe, and its fault directly affects the machining accuracy and productivity of the lathe. Throughout the reliability test bench of the current domestic and foreign CNC tool holder, most of them can only perform reliability testing of a single number-controlled tool holder, and there is a high cost of the test bench, and the spatial utilization rate is low. On the loading of the power head of the servo power tool holder, most of the test beads currently perform torque loading of the power head using only a single-measured power, lack of cutting loading. Add a single load in the loading mode, and the load capacity is low, the torque loading occupancy is large, the effect is lo...
