Non-stop outer diameter measurement method

Abstract

The invention discloses a method for measuring outer diameter without shut down. The method comprises the following steps that 1, a base point is determined: a measurement head of an elastic measurement scale is taken as the base point and approaches to a workpiece, and readings of the measurement scale shake along with rotation of the workpiece when the workpiece in rotation contacts with the measurement head of the elastic measurement scale; 2, calipers descends: the calipers on two sides of the elastic measurement scale descends and contact with the workpiece in rotation under the action of gravity; 3, measurement and calculation are performed on readings: a reading of the base point of the elastic measurement scale and a reading of an included angle of the calipers on the two sides are read, and the outer diameter of the workpiece to be measured is calculated out according to lengths of the calipers. According to the triangle circumcenter law, circumradius is calculated out through readings of three points, and the outer diameter of the workpiece in manufacture is obtained.

Description

technical field [0001] The invention relates to a measuring method in production and processing, in particular to a non-stop outer diameter measuring method, which is mainly used for measuring the outer diameter in the circumferential grinding process. Background technique [0002] The thirties in 18th century, in order to adapt to the processing after the parts such as clock and watch, bicycle, sewing machine and firearms harden, Britain, Germany and the U.S. develop respectively the grinding machine that uses natural abrasive emery wheel. These grinding machines were remanufactured by adding grinding heads to existing machine tools such as lathes and planers at that time. They had a simple structure, low rigidity, and were prone to vibration during grinding. artifacts. In 1876, the universal cylindrical grinding machine made by the U.S. Brown-Sharp Company exhibited at the Paris Exposition was the first machine with the basic characteristics of modern grinding machines. ...

Problems solved by technology

[0003] When grinding and processing outer circular parts, it is often necessary to measure the workpiece during processing to process a workpiece with a certain outer diameter. Since the outer diameter cannot be measured during processing, it is often necessary to stop the machine tool and then measure the stationary workpiece , there is no low-cost and effective method to measure the workpiece in process
