Bearing diameter measurement, bearing diameter size measurement system, bearing diameter measuring device

 Bearing the machinery industry is a very important and very broad application of moving parts, its production volume, high precision. But now, the majority of our bearings manufacturers in the detection of bearing size or rely on mechanical, optical measuring instruments, can not do the detection rate of 100% and a "zero rejection rate," the detection target, manual inspection is easy to produce visual fatigue Therefore low detection efficiency, low precision, narrow range of applications. The project of the machine vision inspection technique to analyze the system to achieve measurement of the bearing bore geometry, the detection system has a non-contact, high speed, high precision, on-site anti-interference ability and relatively low cost, etc., can be widely used in a variety of real-time, on-line precision measurements, especially for dynamic real-time precision measuring part geometry parameters. Machine Vision bearing diameter measuring system consists of five parts: (1) a light source and an optical imaging device; (2) image acquisition card; (3) a computer; (4) motion control card; (5) the mechanical motion platform. The measuring system used in the production line, the measured bearing according to the set tempo on the stage movement, has been adjusted position CCD camera, and image acquisition card to obtain information about the inner diameter of the bearing, the computer using a variety of algorithms for image data calculation processing to calculate the inner diameter of the bearing, the bearing according to preset criteria are divided into different levels, from the sorting mechanism to place to a specific location, while the computer automatically generate statistical reports for printout. Bearing diameter measuring system has the following advantages: (1) the detection rate of 100%, you can better control product quality, and many manual inspection is sampling inspection; (2) a consistent test results, there is no fatigue issues; (3) can be reduce testing costs, improve product quality and reliability; (4) is open to all products bearing, even other mechanical parts (such as gears, bolts, etc.).
