Abstract
The utility model discloses a measuring tool for detecting the diameter of a small hole. The measuring tool comprises a steel ball and the small hole, wherein the diameter of the steel ball is greater than that of the small hole and the steel ball is placed on the small hole of a product. The measuring tool has the advantages of simple structure, convenience for manufacture, easiness for operation, reduction in the measuring difficulty, time economization, improvement of working efficiency and accurate measuring.
Description
Technical field:
The utility model relates to the measurer field, specifically is a kind of measurer that detects hole diameter.
Background technology:
Usually the size of measured hole adopt measurers such as vernier caliper, micrometer caliper, but these measurers all has certain measurement range.For small hole, outside the measurement range of these measurers, and, there is not chamfering again for small hole, vernier caliper, micrometer caliper just have no idea to measure the diameter of micro hole at all.A kind of measurer that detects hole diameter of design mainly is to make the small ball of a diameter greater than aperture now, and steel ball is placed on the aperture, is after utilizing the similar principle of triangle to measure, and calculates the diameter of aperture.This test measuring device is not only easily manufactured, and processing ease has reduced ordinary measring tool and measured difficulty, measures accurately.
The utility model content:
The purpose of this utility model provides a kind of measurer that detects hole diameter, has solved the defective that micro hole is difficult to measure with measurer vernier caliper commonly used.
The technical solution of the utility model is as follows:
A kind of measurer that detects hole diameter comprises steel ball, aperture, it is characterized in that: described steel ball size is greater than hole diameter, and steel ball is positioned on the aperture of product.
Described aperture port does not have chamfering.
The utility model has the advantages that:
The utlity model has simple in structurely, easily manufactured, processing ease has reduced the difficulty of measuring, and has saved the time, has improved work efficiency, measures advantage accurately.
Description of drawings:
Fig. 1 structural diagrams intention of the present utility model.
Embodiment:
A kind of measurer that detects hole diameter comprises steel ball 1, aperture 2, and steel ball 1 diameter is greater than aperture 2 diameters, and steel ball 1 is positioned on the aperture 2 of product 3.Aperture 2 ports do not have chamfering.
Aperture 2 for the diameter that does not have chamfering on the product 3 (1 to 2 millimeter) is difficult to survey with the vernier caliper card accurate.Simple way is to utilize the similar principle of triangle that the steel ball 1 of one known diameter D (2 to 3 millimeters) is placed on the aperture 2, records height m, then aperture 2 diameters
Claims (1)
1. a measurer that detects hole diameter comprises steel ball, aperture, it is characterized in that: described steel ball size is greater than hole diameter, and steel ball is positioned on the aperture of product.
