Problems solved by technology

[0002] Vernier calipers are mostly used to detect the aperture. When it is necessary to detect the distance between two holes, there is currently no good detection tool for detection. First of all, it is not possible to ensure that the center distance between the two holes is correct. At the center of the hole, it is easy to cause the hole distance to be too small or too large during detection. At the same time, when the diameters of the two holes are not on the same straight line during detection, it is easy to be deflected, resulting in a deviation in the detected hole distance. A two-hole center measuring tool is needed for this purpose

Embodiment 1

[0042] A main scale area 4 located on the side of the main body 1 is formed between the top guide groove 2 and the middle guide groove 3. The main scale area 4 is provided with a main scale arranged along the length direction of the main body 1. The starting point of the main scale is located at the front end adjustment assembly 6. Directly below the axis of the adjusting shaft 602, a scale plate is affixed to the top of the baffle plate 601 of the rear end adjustment assembly 9. The scale plate is provided with an auxiliary scale along the length direction of the main body 1, and the starting point of the auxiliary scale is located at the bottom of the rear end adjustment assembly 9. Just above the axis of the adjustment shaft 602;

Embodiment 2

[0044] The indication plate 701 is provided with an aperture scale arranged along its length direction, and the mobile indication plate 702 is provided with an aperture auxiliary scale arranged along its length direction, and the main scale and the auxiliary scale bracket as well as the aperture scale and the aperture auxiliary scale are provided with a vernier caliper. Scale mode is formed.

[0045] working principle:

[0046] When detecting the first detection hole, pull out the pull plate on the front end adjustment assembly 6, move the locking teeth on the collision block to the direction away from the slot, and clamp the front end inner side on the front end clamping assembly 8. The jaws and the front-end outer jaws extend into the hole to be detected, and then push the front-end inner jaws and the front-end outer jaws on the front-end clamping assembly 8 located at the bottom of the front-end lifting adjustment assembly 6, so that the front-end inner jaws and the front-e...

Abstract

The invention belongs to the technical field of measurement tools, in particular to a two-hole center measurement tool. According to the scheme, the tool comprises a body and a front-end instruction component, wherein the body is of a strip structure, a top guide slot, a middle guide slot and a bottom guide slot are formed sequentially in one of the body in the width direction, and the middle guide slot is located between the top guide slot and the bottom guide slot; and the front-end instruction component is located in the top guide slot and is connected with the top guide slot in a sliding mode, a front-end clamping component is fixedly connected to the output end, close to the middle guide slot, of the front-end instruction component, and the front-end instruction component is used fordisplaying inner diameters of adjacent to-be-measured holes. Through the tool, the distance between the two holes is effectively detected, meanwhile it is ensured that the detection diameters of the two holes are located on the same plane, therefore, it is ensured that the distance between the two detection holes does not skew, the distance between the two holes and the diameters of the two to-be-measured holes are visually obtained, and it is convenient for an operator to detect the holes.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a measuring instrument for the center of two holes. Background technique [0002] Vernier calipers are mostly used to detect the aperture. When it is necessary to detect the distance between two holes, there is currently no good detection tool for detection. First of all, it is not possible to ensure that the center distance between the two holes is correct. At the center of the hole, it is easy to cause the hole distance to be too small or too large during detection. At the same time, when the diameters of the two holes are not on the same straight line during detection, it is easy to be deflected, resulting in a deviation in the detected hole distance. Need a kind of two-hole center measuring tool for this reason. Contents of the invention [0003] The invention proposes a measuring tool for the center of two holes, which solves the problems in the prior art. ...
