Integrated caliber

Abstract

The invention relates to a measuring tool, provides a linear dimension measuring tool and especially relates to an integrated caliber. The integrated caliper has inner caliper and outer caliper two states, and comprises a pair of caliper arms, which are symmetrically arranged and are in cross hinge through a rotation pin, wherein one section, at one side of the rotation pin, of each caliper arm is a clamping section, and the other section is a reading section. The end portion of each clamping section is provided with a caliper head, the included angle between which and the caliper arm is adjustable in the plane defined by the pair of caliper arms; the two caliper heads, the front ends of which are sharp ends, are symmetrically arranged; when the caliper heads tilt inwardly, the caliper is an inner caliper, and when the caliper heads tilt outwardly, the caliper is an outer caliper; the reading section is provided with a reading device for reflecting the length of the inner caliper and the length of the outer caliper; the caliper heads are rotatably arranged at the end portions of the clamping sections respectively through control screws; the two sides of the back end of each caliper head are respectively provided with a limit lug for limiting the caliper head from tilting inwardly and outwardly to an extreme position; and when the caliper heads tilt inwardly or outwardly to the extreme position, the included angle between the axis of the caliper head and the axis of the clamping section is 12 degrees and 25 degrees.

Description

technical field [0001] This technology relates to measuring tools, and provides a linear dimension measuring tool, especially an integrated caliper, which can be used as an inner caliper when measuring dimensions such as wall thickness, and can be used as an outer caliper when measuring dimensions such as inner hole diameter. , and can directly read out the measured data. Background technique [0002] In the prior art, when measuring linear dimensions such as wall thickness, inner hole diameter, and groove width of parts, inner calipers and outer calipers are often used for auxiliary measurement. After the opening of the calipers corresponds to the size to be measured, the calipers need to be removed. Using other measuring tools to measure the linear dimension of the caliper opening, the test results are affected by the skills of the inspectors, it is difficult to ensure that the caliper opening does not change, and it is also difficult to ensure the accuracy of the measurem...
