Method and device for detecting central position of rotating shaft of cradle turntable

The invention provides a method and a device for detecting the central position of a rotating shaft of a cradle turntable. The cradle turntable comprises a plurality of rotating shafts, a rotating workbench and a display interface, the plurality of rotating shafts comprise a C shaft, an X shaft, a Y shaft and a Z shaft, the plurality of rotating shafts further comprise an A shaft or a B shaft, theZ shaft is a main shaft, the detection method comprises the following steps: acquiring the length of a standard part, and mounting the standard part on the main shaft; controlling a dial indicator tobe mounted on a rotary worktable; at least controlling the to-be-measured shaft to rotate by a preset angle; and determining the position of the to-be-measured axis according to the X-axis reading and the Y-axis reading of the display interface, wherein the position comprises an X-axis coordinate, a Y-axis coordinate and/or a Z-axis coordinate. According to the method, the dial indicator on the rotary workbench is moved b
