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

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

[0021] see figure 1 , figure 2 As shown, a multifunctional 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 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. The two chucks 2 with pointed ends are symmetrically arranged, and the chuck 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 selected as 6mm according to empirical data. In order ...

Abstract

The invention provides a linear size measuring tool, especially multifunctional 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; when the clamping heads incline inwardly / outwardly to limit positions, the included angle between the axis of the clamping heads and the axis of the clamping segments is 12 / 25 degree; the rear end of the two reading segments are provided with grooves opposite to each other, and grooves are used to accommodate clamping pins of a vernier caliper.

Description

technical field [0001] The technology relates to measuring tools, and provides a linear dimension measuring tool, especially a multifunctional 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 me...
