The second Y-axis fine-tuning slide 54 is used to install the camera rotation mechanism 52, and is used for precise fine-tuning of the camera rotation mechanism 52 along the Y-axis direction. By adjusting the second Z-axis fine-tuning slide 53 and the second Y-axis fine-tuning slide 54 The rotation center of the camera rotation mechanism 52 is coaxial with the OA shaft core 200 located at the secondary positioning station.

Before use, the secondary positioning unit 50 needs to be adjusted as follows: (1) First, adjust the second Y-axis adjustment bolt 55 to make the rotation center line of the camera rotation mechanism 52 and the rotation center of the OA shaft core 200 at the secondary positioning station The lines are parallel; (2) Then adjust the second Z-axis fine-tuning slide 53 and the second Y-axis fine-tuning slide 54 so that the rotation center of the camera rotation mechanism 52 is coaxial with the OA shaft core 200 at the secondary positioning station.

Please refer to Figures 10 to 12 together.

d尺寸的真圓度來表示，真圓度越大，誤差越小，反之，誤差越大。 During the secondary positioning, the camera rotation mechanism 52 drives the secondary positioning camera 51 to continuously rotate in the subdivision interval of the remaining deflection angle α-β, so that the secondary positioning camera 51 is repeatedly within the subdivision interval of the remaining deflection angle α-β. Take a picture and calculate the error value, the error value is in a normal distribution, so as to realize the process of multiple measurement errors from large to small and then to large. The position with the smallest error value is used as the best measurement position, and a photo closest to the ideal angle can be obtained. The value of the error is based on the inner hole diameter calculated by the first area scan camera 511

The roundness of the d dimension is expressed, the greater the roundness, the smaller the error, and vice versa, the greater the error.

測量誤差範圍，當e=0.1°時，則滿足測量精度要求。 In this embodiment, the camera rotation mechanism 52 rotates 0.1° each time to meet the accuracy requirements of the measurement, and continuously rotates at most 10 times, and then selects the position with the smallest error for measurement. Take the thickness dimension of the end face of the OA shaft core 200 to explain: (1) The actual size is based on the tolerance and the upper limit value is H; the deflection angle is e; the camera calibration size/actual size=cos(e×2 π/360); (2) )Camera calibration size=H×cos(e×2π/360); actual size-camera calibration size
