Abstract
The utility model discloses a dedicated detecting tool for detecting the internal dimension and the external dimension of a universal caliper. A square main shaft successively passes through four measuring blocks. The two ends of the square main shaft are equipped with positioning screw nuts. Locking screw nut caps are disposed on the outer sides of the positioning screw nuts. Three groups of caliper-dedicated measuring blocks are disposed between the two sides of the square main shaft and the four measuring blocks. By square main shafts with different length, the measuring blocks and the caliper-dedicated measuring blocks are arranged alternatively. Therefore, not only is an external dimension measuring standard of original caliper-dedicated measuring blocks reserved, but also an internal dimension measuring standard can be formed on two end faces between measuring blocks. As a result, the defect that the original caliper-dedicated measuring blocks has no internal dimension measuring standard is overcome and a requirement specified by a verification regulation is satisfied. The dedicated detecting tool has characteristics of simple and fast measuring blocks installing steps, outstanding torsion balance effect of the positioning screw nuts, wide view of detecting calibration readings, and safe and reliable use and operation, and effectively guarantees detecting and calibrating quality so as to increase work efficiency.
