Problems solved by technology

Due to the large equipment, this method is more commonly used in workshops or laboratories. For construction sites or other places where it is not convenient to carry heavy testing equipment, conical plug gauges are generally used for measurement. The general accuracy of conical feeler gauges can only reach 0.1mm, and prone to measurement errors

Abstract

The invention discloses a digital display feeler gauge for measuring a small aperture and a working method thereof, and belongs to the technical field of measuring tools. A vernier is installed on themain ruler in a sliding mode, one end of the vernier is fixedly connected with the positioning block, one end of the main ruler is fixedly connected with the bottom face of the semi-conical feeler gauge, and the vertical section of the semi-conical feeler gauge is tightly attached to the side face of the positioning block. And when the main ruler and the vernier are tightened, the vertex of the semi-conical feeler gauge is aligned with the end part of the positioning block. A capacitive grating sensor, a processor and a data processing module are arranged in the vernier, and a digital displayscreen is arranged on the vernier; the capacitive gate sensor is connected with the data processing module, and the processor is connected with the digital display screen and the data processing module. The device can quickly measure the aperture of a small part, is high in numerical value precision, and can remarkably improve the working efficiency and the speed and accuracy of data collection.The method is simple to operate, does not depend on the skill level of operators, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of measuring tools, and relates to a digital display feeler gauge for measuring small apertures and a working method thereof. Background technique [0002] At present, for parts that need to accurately measure the inner diameter, a special electronic magnifying glass is generally used to zoom in and take pictures, and then use recognition software to detect the diameter of the part photo. Due to the large equipment, this method is more commonly used in workshops or laboratories. For construction sites or other places where it is not convenient to carry heavy testing equipment, conical plug gauges are generally used for measurement. The general accuracy of conical feeler gauges can only reach 0.1mm, and prone to measurement errors. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a digital display feeler gauge for measuring small ape...
