[0028] Working principle: The user of the detection machine of the present invention first puts the workpiece into the fixture 22, puts the nut on the top of the workpiece, and then starts the machine. The locking component 26 and the detection component 27 are driven by the first cylinder 28 and the second cylinder 36 to move downward, and the locking head 38 is connected to the nut set above the workpiece. At this time, the motor under the fixture works to drive the fixture 22 to rotate, so that the nut is locked, and the detection convex point 34 of the detection component is connected to the detection hole 9 on the fixture. In the process of locking the nut, the tripping value of the workpiece is first debugged to a certain range, and then the speed of the motor at the lower end of the fixture 22 is reduced and rotated slowly to improve the accuracy of the tripping value.
