Tubular Product Size Detection Technology

Manual measure tools, such as micrometer were used to measure outside and inside diameter of tube product, which is effected by people factor and has long measuring period and low precision and dose not fulfill the on-line measuring need of batch production .So, according to the product line structure of tube product, The on-line measuring method with linear CCD is brought forward in this article and imitating operation is done by the mentioned method.Firstly, Product line structure of tube product is introduced. Systemic measure scheme is designed on the basis of product line structure and every component of measuring system is specified. Secondly, tube product shape imitating ,rolling imitating of on-line tube product ,measuring the chordlength imitating with CCD and dimension measure arithmetic-circle leastsquare estimation are finished. Lastly, according to mentioned dimension measuring method ,imitating operation and the result of imitating operation are emphatically analyzed.
