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.

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, this technology is further described:

[0022] see figure 1 , figure 2 As shown, a direct reading integrated internal and external caliper includes a pair of pliers arms 10 symmetrically arranged and cross-hinged by a rotating pin 9. Each pliers arm 10 is a clamping segment 11 on one side of the rotating pin 9, and the other side is It is the reading section 12; at the end of the clamping section 11, there is a chuck 2 that can be adjusted in the plane determined by the pair of pliers arms 10 and the angle between the pliers arms 10, and the two chucks 2 with pointed ends are arranged symmetrically. When the card head 2 is tilted inward, it is an inner card (see image 3 shown), when the card head 2 is tilted outward, it is a wild card (see Figure 4 shown); in the reading section 12 is also provided with a reading device.

[0023] The thickness of the pliers arm 10 is constant, and the thickness of the pliers arm 10 ...

Abstract

The invention relates to a measuring tool, provides a linear dimension measuring tool and especially relates to an integrated inner / outer caliper capable of realizing direct reading. The 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 through control screws respectively; and 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.

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...
