Direct reading integrated hermaphrodite caliper

Abstract

This technology relates to measuring tools, and provides a linear size measuring tool, especially a direct reading integrated inner and outer calipers, which have two states of inner clamp and outer clamp, including a pair of clamp arms that are symmetrically arranged and cross-hinged by rotating pins. One side of each pincer arm is a clamping section, and the other side is a reading section; at the end of the clamping section, there is a chuck that can adjust the angle between the clamp arm and the clamp arm in a plane determined by a pair of clamp arms. The two chucks with pointed fronts are arranged symmetrically. When the chuck is inclined inward, it is an inner card; ;When the chuck tilts inward to the limit position, the included angle between the chuck axis and the clamping segment axis is 12°; when the chuck tilts outward to the limit position, the included angle between the chuck axis and the clamping segment axis is 25°.

Description

technical field [0001] The technology relates to measuring tools, and provides a linear size measurement tool, especially a direct reading integrated internal and external caliper, which can be used as an internal caliper when measuring wall thickness and other dimensions, and can be used for measuring inner aperture and other dimensions. It can be used as an external caliper and can directly read out the measurement 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 a...

Problems solved by technology

[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. Use 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 difficult to ensure the accuracy of the measurement.

In addition, the common caliper in the prior art is a single inner caliper and outer caliper, which has a single function, cannot directly read the measurement results, and cannot meet the requirements of direct and effective measurement.
