Integrated clamp

Abstract

The invention relates to a measuring tool, and provides a linear size measurement tool, especially an integrated clamp. The clamp has two states: internal clamping and external clamping. The clamp comprises a pair of clamp arms which are arranged symmetrically and are hinged to each other in an intersected manner through a rotating pin. A part, at one side of the rotating pin, of each clamp arm is a clamping segment, and a part, at the other side of the rotating pin, of each clamp arm is a reading segment. End parts of the clamping segments are provided with a pair of clamping heads, wherein inclined angles between a plane defined by the pair of clamp arms and the clamp arms can be adjusted. The two clamping heads with the pointed front ends are arranged symmetrically. When the clamping heads are inclined inwards, the clamping heads are in the state of internal clamping; when the clamping heads are inclined outwards, the clamping heads are in the state of external clamping. The reading segment are provided with reading devices which are used for reflecting an internal clamping length and an external clamping length. The clamping heads are rotatingly disposed at the end parts of the clamping segments through control screws, and two sides of the rear end of each clamping head are provided with limiting bosses which are used for limiting the corresponding clamping head to be inclined inwards and outwards to a limit position. When the clamping heads are inclined inwards and outwards to the limit positions, the inclined angles between the axes of the clamping heads and the axes of the clamping segments are 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 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 also difficult to ensure the accuracy of the measu...

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.
