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.

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, this technology is further described:

[0021] see figure 1 , figure 2 As shown, an 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 section 11 on one side of the rotating pin 9, and a reading section on the other side. Section 12; the end of the clamping section 11 is provided with a chuck 2 that can be adjusted in a plane determined by a pair of pliers arms 10 and the included angle with the pliers arms 10, and the two chucks 2 with pointed ends are symmetrically arranged at the front end, and the chucks 2 Inner card when tilted inward (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.

[0022] The thickness of the pliers arm 10 is constant, and the thickness of the pliers arm 10 is...

Abstract

The invention relates to a measuring tool, provides a linear dimension measuring tool and especially relates to an integrated inner and outer caliper. 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 clamping section is provided with a locking device for locking the pair of caliper arms in a certain included angle; and the front end of each caliper head is in a cone shape.

Description

technical field [0001] The technology relates to measuring tools, and provides a linear dimension measuring tool, especially an integrated inner and outer 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. The calipers are used and the measurement data can be read out directly. 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 difficu...
