Diameter grabbing and measuring device and its measuring method

Abstract

The present invention provides a diameter gripping and measuring device and a measuring method thereof. The diameter gripping and measuring device includes a measuring module, a bottom plate, a through hole in the bottom plate, a material presence inductor and a rotating module which are located on the bottom plate, a rotary fixing plate, a first material gripping device and a second material gripping device; the rotary module drives the rotary fixing plate to rotate so that the first material gripping device and the second material gripping device can be switched between a feeding position and an unloading position; the first material gripping device and the second material gripping device sequentially grip the cylinder of a measured object to a first driving device and a second driving device, so that the cylinder of the measured object can be gripped by the first driving device and the second driving device; and a displacement sensor measures the diameter of the cylinder of the measured object. With the diameter gripping and measuring device and the measuring method thereof of the invention adopted, the outer diameter of the cylinder is not required to be manually measured through calipers; a servo motor is adopted as a driver, and an externally-arranged high-precision grating ruler is adopted as full closed-loop output signals, and therefore, the precision of an output measurement value can be ensured; and production cost can be effectively saved, automated detection degree is improved, and the improvement of the fully-automated production level of factories can be benefitted.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a diameter grabbing and measuring device and a measuring method thereof. Background technique [0002] With the continuous improvement of the automation of factory production, in order to improve production efficiency, the proportion of automatic production lines is increasing. In the production process of some precision electronic components, it is necessary to strictly control the outer diameter of the product. The outer diameter measurement of most round products is usually manually measured with calipers. In the process of mass production of products, the method of manually measuring with calipers can no longer meet the needs of production, and the manpower of using calipers to measure The cost is high, and it cannot meet the measurement of the outer diameter of the product in the mass production of factory automation. [0003] Therefore, it is necessary to d...
