Method for detecting microscopic state of round broach

The invention relates to a method for detecting the microscopic state of a circular broach, and the method comprises the following steps: horizontally installing a supporting base on the ground, adjusting the positions of two movable supporting seats on the supporting base to be matched with the length of the circular broach, respectively placing the two ends of the circular broach on the two movable supporting seats, and carrying out the detection of the microscopic state of the circular broach. The measuring mechanism moving on the side wall of the supporting base is used for shooting the rotating circular broach of the movable supporting base, and the actual microscopic state of the broach is recorded. In the round broach detection process, round broach movable supporting bases of different specifications can be conveniently matched, according to different detection parts, the first motor drives the measuring mechanism to adjust the position, the second motor works to achieve rotation of the round broach,
