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 provides a linear size measuring tool, especially inside and outside integrated calipers, and belongs to measuring tools. 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; the clamping segments are provided with a locking device which locks the pair of caliper arms in certain included angle; and the front ends of the clamping heads form a wedge 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...
