Embodiment Construction

[0040] In order to make the technical purpose, technical solution and technical effect of the present invention clearer, so that those skilled in the art can understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as figure 1 as shown, figure 1 A schematic structural view of a three-point caliper in a preferred embodiment of the present invention is shown. The three-point caliper includes a main ruler 1, and a sliding groove 11 is opened on the main ruler 1; the three-point caliper also includes a movable ruler body 8 slidably arranged in the sliding groove 11;

[0042] One side of the main ruler 1 is formed with a first extension part 12, and the other side is formed with a second extension part 13; the first extension part 12 protrudes and forms a first fixed measuring claw 2, and the second extension part 13 protrudes and forms Ther...

Abstract

The invention provides a three-point caliper and a measuring method thereof. The three-point caliper comprises a main caliper (1), and a sliding groove (11) is formed in the main caliper (1); the three-point caliper further comprises a movable caliper body (8) which is arranged in the sliding groove (11) in a sliding mode; a first extension part (12) is formed on one side of the main caliper (1), and a second extension part (13) is formed on the other side of the main caliper (1); a first fixed measuring claw (2) is formed on the first extension part (12) in a protruding manner, and a second fixed measuring claw (3) is formed on the second extension part (13) in a protruding manner; the first fixed measuring claw (2) and the second fixed measuring claw (3) are symmetrically arranged by taking the symmetric surface of the sliding groove (11) as the symmetric surface; and a movable measuring claw (4) is formed on the movable caliper body (8) in a protruding manner. The three-point caliper and the measuring method thereof are novel in design and high in practicability.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a three-point caliper and a measuring method thereof. Background technique [0002] A caliper is a measuring tool used to measure length, inner and outer diameters, and has the functions of measurement and inspection. When using a caliper to measure the hole diameter, the inner diameter measuring claw is easy to slide on the surface of the part, resulting in the cutting edge of the inner diameter measuring claw not being stuck on the diameter of the hole, making the measured value smaller. Contents of the invention [0003] The object of the present invention is to propose a three-point caliper and its measuring method for the above-mentioned technical problems. [0004] The technical scheme that the present invention solves its technical problem is: [0005] The present invention proposes a three-point caliper, which includes a main ruler on which a sliding groove is opene...
