Fast measuring device for distance between hole and plane

Abstract

The invention relates to a fast measuring device for the distance between a hole and a plane. The fast measuring device comprises a handle, a mandrel, a supporting arm and a measuring gauge. The mandrel is fixed to the lower end of the handle, the handle is of a cavity structure, one end of the supporting arm is arranged in a cavity of the handle in a sleeved mode and connected with the bottom of the cavity of the supporting arm through a spring, a thread is arranged on the inner wall of the part, at the upper end of the supporting arm, of the handle, a bolt is further arranged at the upper end of the handle, the other end of the supporting arm is arranged outside the handle and is connected with the measuring gauge, and a groove for radial movement of the supporting arm is formed between the supporting arm and the lower end of the handle. The fast measuring device has the advantages that measuring is convenient, precision is high, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of measuring instruments for the position and size of mechanical parts, in particular to a fast measuring device for the distance between a hole and a plane. Background technique [0002] The accuracy requirements for the processing of some mechanical parts are relatively high, such as the pump cover. For the distance between the center of the hole on the pump cover and the plane, the assembly accuracy should be considered, and the size of the distance should be controlled. However, the general measurement is relatively Difficult, when a surveyor uses ordinary measuring tools to measure, he needs to use multiple measuring tools for calibration, and even one person cannot operate it, and needs the assistance of other personnel; if you want to measure the distance of multiple positions, you must continue to calibrate, which is not only troublesome, but also time-consuming Laborious and inefficient.
