A device for measuring the position degree of disc hole

Abstract

The invention relates to a device for measuring the position of a disc hole, which includes a slide rail, a long hole arranged on the slide rail, and a positioning device fixed under the slide rail after passing through the long hole through the butterfly bolt IV and the butterfly bolt V respectively. The pin I and the positioning pin II, the L-shaped meter seat and the measuring slide seat arranged between the positioning pin I and the positioning pin II. By recording the readings of the dial indicator, after measuring all the holes, the average of all the readings is taken as the theoretical standard reading, and the difference between the actual reading of each measuring hole and the theoretical standard reading is the position deviation value of the measuring hole, the difference The positive or negative of reflects the direction of position deviation. The measurement method is simple and easy, and the measuring device has a simple structure and strong mobility. It can directly replace large-scale measuring equipment such as three-coordinates, and complete the task of quantitatively measuring the position of the plate hole anytime and anywhere, reducing measurement costs, improving measurement efficiency, and improving machining efficiency. Productivity.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a device for measuring the position degree of disc holes. Background technique [0002] In the field of mechanical manufacturing, mechanical workpieces with disc holes processed on circular or annular sections are often encountered. When measuring the position of the disc holes of such workpieces, the commonly used detection method is to use a special disc hole position gauge to detect , as attached figure 1 As shown, if the measuring pin of the gauge can be inserted into the plate hole, the workpiece is qualified, otherwise it is unqualified. This method has certain limitations. It can only qualitatively detect whether the position of the disc hole meets the process requirements, but cannot quantitatively measure the deviation value and direction of the position of the disc hole. Especially for the field of machining, it is difficult to meet the measurement requi...

Problems solved by technology

This method has certain limitations. It can only qualitatively detect whether the position of the plate hole meets the process requirements, but it cannot quantitatively measure the deviation value and direction of the position of the plate hole.

Especially for the field of machining, it is difficult to meet the measurement requirements with simple qualitative measurement whether the workpiece is qualified or not.

[0003] In order to be able to quantitatively measure the deviation value and deviation direction of the disc hole position, people usually use large-scale professional testing equipment such as three-coordinate measuring instruments, which not only has high measurement costs, but also has relatively poor mobility and flexibility.

It is difficult to meet the requirements of quantitative measurement anytime and anywhere on the production site
