Embodiment Construction

[0012] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.

[0013] A distance measuring method proposed by the present invention is used to measure the distance from the hole whose center line of the hole is parallel to the plane of the inner wall of the box to the plane, comprising the following steps:

[0014] S1. Design a distance measuring device. The overall structure is a slender rod assembly structure, which is composed of a fixed end 1, a moving end 3, and an intermediate rod 2. The fixed end and the moving end are respectively fixed at both ends of the intermediate rod. The rod is threaded, and the distance is shifted through the screw to adjust the position of the moving end 3 and the middle rod. The stroke △A relative to the initial position can be accurately measured with a feeler gauge, so that the distance measurement can be c...

Abstract

The invention relates to a distance measuring method, and the method is used for measuring the distance from a hole, the center axis of which is parallel to the plane of the inner wall of a box body,to a plane; the measurement of the distance is converted into the measurement of the travel distance of a mobile end by measuring the travel distance of the mobile end, and the travel distance can beaccurately measured by a feeler gauge, so that the measurement precision is improved. The method is suitable for the measurement of a long distance, wherein the size range of a measured element is known and the center of a hole of the measured element is opposite to the plane of the inner wall of a shell of another measured element; the method solves the problem of inaccurate measurement data in the prior art, and avoids the condition that a large-size tubular inside micrometer needs n extension rods for length connection. The geometrical shape of the inner cylindrical surface of a fixed end provides a line contact state internally tangent to a measured element, so that a measurement point position of the end does not need to be found and determined, the operation is very convenient, the practicability is high, the cost is low, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a distance measurement method, which is used for measuring the distance between the center line of a hole on a box-type structural member and the plane of the inner wall of the box. Background technique [0002] In order to measure the distance between the center of the hole on the box-type structural parts and the plane of the inner wall of the box, the existing technology is roughly measured with a steel tape or a ruler; for accurate measurement, the precise mandrel penetrated into the hole is used, and then a tubular inner diameter micrometer is used to measure the distance. Measurement. After the measurement, sum the obtained value and the radius value of the measured part, and the calculated "sum" is the value of the distance. For large-sized inner diameter micrometers, it is difficult to determine the position of the measured point circumscribed between the...
