The Key Technology Research Of Multifunctional Probe About Big Distance Of Porous Parts

At present,there are relatively scarce testing equipments to test the big distance distributionsystem very precise in our country.This topic mainly research the key technology in multifunctionltest head,rooting in the measure of the big distance distribution system.It is the needs to assurancetechnology of the the big distance distribution of pore size. Solving the key problems of the big holedistance distribution system alignment measuring system in the process of measurement,to perfect thetheory system and technical measurement.It is better to applied to practical production measurementand to fill the bank of the domestic in the field of measurement at present.The article expounds the necessity research on the key technology of the multifunctionl test headand the measuring principle and solution.Putting forward the methods to set up a new system of thecoordinate system,which is based on high precision dual-axis tilt sensors,which is a simple andaccurate method. The principle of measurement is that to realize measuring jaw stretched out andreset,through the rotating mechanism driven by dc servo motor,so as to realize measurement of porediameter.To get the center coordinate through the front center PSD,to get coaxial tolerance by dateprocessing under the absolute coordinate.And introduce the integrated basic structure of the head indetails, the optimization of components in the probe design ang analysis.And according to differentparts and assembly parts,making the detailed process to ensure that its precision machining andassembly. Finally to analysis the error of measuring jaw structure and the precision of the dual-axistilt sensors installation influence on system.Eventually develop a measured parts according to theactual shape,size,which can achieve interchangeable type multiscale self-centering comprehensivemeasuring head.It realize the hole parts of high precision and high intelligent measurement.
