Multipurpose digital display internal micrometer

Abstract

The invention discloses a multipurpose digital display internal micrometer. The multipurpose digital display internal micrometer comprises elbow measuring frames (20) which can be assembled with replaceable measuring heads and various types of replaceable measuring heads (8 and 14); the elbow measuring frame on the left side can be adjusted through nuts (16 and 18); the elbow measuring frame on the right side can synchronously move backward and forward along with a micrometric screw (22) of the multipurpose internal micrometer; and the size of an object to be measured is displayed through a digital display device. The multipurpose digital display internal micrometer is particularly more convenient and faster in the aspects of size measurement and read of internal diameters, internal threads and internal channels.

Description

Multi-purpose digital inner diameter micrometer technical field The invention relates to a digital display inner diameter micrometer, in particular to a multipurpose digital display inner diameter micrometer capable of directly measuring and reading various inner diameter sizes. Background technique At present, the commonly used inner diameter measurement tool mainly uses the inner diameter dial indicator and the outer diameter micrometer to obtain the inner diameter size. For the measurement of the pitch diameter of the internal thread, although there is a straight rod type internal thread micrometer, it is also limited by the size of the inner diameter, and cannot measure the inner diameter, inner thread, inner groove and other inner diameters faster and more conveniently. Contents of the invention The purpose of the present invention is to design a multi-purpose digital display inner diameter micrometer, which can measure various inner hole sizes through various inte...
