Device and method for measuring the thickness and position tolerance of a wheel bolt hole
A device and method for measuring the thickness and position tolerance of a wheel bolt hole. The device includes a screw, a handle, a detection pillar and a base plate, where the handle and the base plate are fixed via the screw; the detection pillar is fixed onto the base plate through interference fit; and the detection pillar a bolt hole. The position tolerance and thickness of a bolt hole are measured simultaneously, and the labor intensity is reduced, and the existing bolt hole position tolerance detection tool can be modified for the use as the tool of the device, saving costs. The tool can detect the thickness of a bolt hole and qualitatively determine the range where the difference between the value of bolt hole thickness and the standard value approximately lies, and can be used for the grading of bolt hole thickness values based.
