Integrated multifunctional calipers

Abstract

The invention provides integrated multifunctional calipers. The calipers include an inside-calipers state and an outside-calipers state; the calipers comprise a pair of caliper arms, the two caliper arms are arranged symmetrically and are hinged to each other in an intersected manner via a rotational pin, the side, of the rotational pin, of each caliper arm includes a clamping segment, and the other side of the caliper arm includes a reading segment; the end portion of each clamping segment is provided with a clamping head, the included angle between the clamping head and the caliper arm in a plane defined by the pair of caliper arms can be adjusted, two clamping heads whose front ends include tips respectively are arranged symmetrically, when the clamping heads incline inwardly, the calipers serve as inside calipers, and when the clamping heads incline outwardly, the calipers serve as outside calipers; the reading segments are provided with a reading device which reflects the lengths of the inside calipers and the outside calipers; each clamping head is arranged in the end portion of the corresponding clamping segment rotationally, and the two sides of the rear end of the clamping head are provided with limiting bosses which limit the clamping head to incline inwardly/outwardly to a limit position; and the reading device is includes bevel gauges with arched kidney-shaped holes, two guide columns are arranged in each kidney-shaped hole movably, one guide column is connected with the corresponding caliper arm, and the two sides of each bevel gauge are provided with graduation lines corresponding to the lengths of the inside calipers and the outside calipers.

Description

technical field [0001] This technology relates to measuring tools, and provides a linear dimension measuring tool, especially an integrated multifunctional caliper, which can be used as an inner caliper when measuring dimensions such as wall thickness, and can be used as an inner caliper when measuring dimensions such as inner hole diameter. It is 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 al...

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.
