[0003] When measuring the displacement dimension between the product raceway and the inverter, the visual method and the red oil rubbing method are usually used. The visual method is to judge whether the displacement dimension deviation between the raceway and the inverter meets the requirements based on the experience of the machine adjustment personnel. In this process, everyone's experience is different, and the judgment results are also different. There will be a large error, which is relatively limited. The red oil rubbing method is to pre-process a spiral line on the inner wall of the nut, use ink to apply it on the spiral line, and measure it with white paper to roughly measure the left and right deviation values. In this process, the thickness of the line copied by the red mud is different, and the measurement results are also different, which also leads to measurement deviation. The above two methods cannot accurately measure the error value, which affects the measurement results, leads to instability in the subsequent processing, and reduces the product qualification rate; therefore, a contact nut raceway displacement measuring device is proposed to address the above problems.
