Abstract

The intention belongs to measurement tools for the measure caliber rule with the infinite accuracy. The rule includes the fixed scale and the motion rule A. The motion ruler of the short ruler is installed in the seat of the short ruler. Turning the rotation knob makes the relative displacement between the motion ruler and the fixed scale. Through the gear drive pair, the engaged motion ruler of the long ruler is interlocked with the speed-increasing ratio. The assistant ruler is installed in the seat of the short ruler. Turning the rotation knob makes them the relative displacement. The assistant ruler possesses the positioning set B. Similarly, The motion ruler of the long ruler is installed in the seat of the long ruler. The engaged motion ruler. of the short ruler is interlocked with speed-decreasing ratio.

Description

technical field [0001] The invention belongs to a measuring instrument, in particular to a caliper with infinite measuring precision characterized by the use of a mechanical measuring method. Background technique [0002] In the known technology, the measurement value and accuracy of the caliper are determined by the displacement change of the dynamic and fixed caliper and the ratio of multiple scale values ​​formed by the dislocation change. For example, the "high-precision vernier caliper" disclosed in Chinese patent application CN93118277 and the "micrometer complex vernier caliper" disclosed in Chinese patent ZL86101318, the technical solutions of both are aligned and displayed by adding multiple scales with dislocation changes. Because the trajectory of the scale value is relatively messy, and the numerical precision of its measurement is definite and unchanged. It brings inconvenience to the measurement work with special function requirements. Contents of the invent...
