Abstract

The invention relates to a device and method for measuring circular objects. The device includes: a first panel, a second panel and a main control module arranged on the first panel, the first panel and the second panel are connected through a coaxial mechanism; wherein, the first end of the first panel is a first arc shaped plate, the second end of the second panel is a second arc-shaped plate; the first arc-shaped plate is provided with a first inscribed circle contact sensor and a first circumscribed circle contact sensor, and the second arc-shaped plate A second inscribed circle contact sensor and a second circumscribed circle contact sensor are provided on the device; an angle sensor is also provided on the device, and the angle sensor detects the first contact formed between the centerline of the first panel and the centerline of the second panel. Angle, the main control module determines the inner diameter measurement parameters of the measured circular object according to the first angle and the structural parameters of the first arc-shaped plate and the second arc-shaped plate. The invention can shrink the device, thereby reducing the overall size of the device, and is convenient to use and carry.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a device and method for measuring a circular object. Background technique [0002] Circular objects abound in real life, but the measurement of their radius and circumference is more complicated. The pots and pans we use in our daily life, the fruits and vegetables we taste, the ornamental flowers and trees, and the steel cables for construction all have circular structures without exception. To cooperate with objects of other shapes, this kind of cooperation needs to consider the matching problem between the dimensions of the circular structure, and the most basic data for matching the size is the radius or circumference of the circular object. [0003] The three-point contact method in the prior art is a quick way to measure the radius or circumference of a circular object. The measuring tools can be divided into digital diameter gauges and graduated radius gauges. The cu...
