Problems solved by technology
However, this device cannot realize the measurement of the double screw feed system, let alone the influence of the span of the screw on the dynamic characteristics of the double screw feed system; A connecting plate is designed in between, and the distance between the guide rails can be adjusted by adjusting the connection position between the slider of the guide rail and the connecting plate, but the adjustment range of the distance between the guide rails is limited by the size of the connecting plate itself
[0005] It can be seen from the above that at present, when testing the dynamic characteristics of the machine tool feed system, there is no device that can test the dynamic characteristics of both the single-screw feed system and the double-screw feed system, and there is no device that can realize the span adjustment of the double-screw
