Because the shaft race structure is more complicated, its circumference usually can set up fixed presser foot, mistake proofing presser foot, occasionally still has the location presser foot. When the vernier caliper is used for measurement, the size state of the whole section cannot be accurately reflected because only local point taking is performed; when the three-coordinate measuring instrument is used for measurement, accurate abdication is needed to be carried out on the press claw, so that a measuring path is required to be planned once for each measuring type of shaft seat, the measuring time is long, and the requirement of rapid measurement is difficult to meet; when the non-return gauge is used for measurement, the position of the pressing claw is required to be abdied, the dimension in the whole inner diameter or outer diameter direction cannot be measured, the outer diameter can only be measured to the maximum point, the inner diameter can only be measured to the minimum point due to the limitation of the measurement principle, and when the local dimension is bad, the accurate measurement is difficult; when the bearing instrument is used for measuring, because the structure is specially designed for the solid bearing, the deformation of the part is easy to cause when the thin-wall part is measured, the size and the position of the measuring head cannot be matched with the universal type, each part needs to be customized, and the cost is high.
