Abstract

The invention provides a vernier caliper used for hole distance measurement. The vernier caliper comprises a main ruler, wherein the main ruler is provided with a gradienter used for detecting the level condition of the main ruler; the lower surface of the main ruler is provided with a fixed caliper inserted into one to-be-measured hole of a workpiece; the main ruler is provided with a sliding seat in a sliding way; the side surface of the sliding seat is provided with a vernier; and the bottom of the sliding seat is provided with a sliding caliper component which is inserted into the other to-be-measured hole of the workpiece or fit to the to-be-measured surface of the workpiece and can slide along the main ruler. The above vernier caliper used for hole distance measurement can quickly and accurately position the center of a circle of the to-be-measured hole so as to quickly detect an interval between two holes and an interval between a hole and a surface. The vernier caliper has theadvantages of being simple in structure, convenient in operation, accurate in measurement and the like.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a vernier caliper for hole distance measurement. Background technique [0002] As we all know, a vernier caliper is a precision instrument used to measure the length of an object, which can achieve accurate measurement of the diameter of the object, but the measurement of the hole spacing has a large error. [0003] In the prior art, the method of using the vernier caliper to measure the hole distance is: use the vernier caliper to measure the shortest distance between the hole edge and the hole edge, and then combine the radii of the two holes to calculate the distance between the two holes; or use the vernier caliper to roughly obtain the distance to be measured. The distance between the hole and the surface to be measured or the measurement line. It can be seen from this that the measurement error is large and the measurement efficiency is not high.
