For example, when the concentricity of the pads is measured by using a dial indicator in the precision of the tire processing equipment, an operator needs to hold a pointer to read the center of each pad, the whole process passes through 12 pads, and the measurement needs to be carried out again when slight shaking or over-range occurs, so that the accuracy of data is influenced; secondly, the overall verification time is too long and requires at least 2-3 people to make the measurement adjustments. For another example, when the perpendicularity of the crown transmission ring is measured, due to the fact that a plurality of bolts are arranged on the outer side of the ring body, when the dial indicator is used for measurement, the dial indicator is in a contact structure, and the measurement is prone to being blocked and cannot be conducted.
