DEVICE FOR CHECKING SIZES OF ARTICLES WITH LONGITUDINAL AXIS OF SYMMETRY Russian patent published in 1998 - IPC

FIELD: checking and measurement of parameters of curvilinear surfaces. SUBSTANCE: device has horizontal table provided with two independent drives designed to move table along two mutually perpendicular axes of horizontal plane (along axes X and Y). To perform measurements, table is fitted with pickups of linear motion (along axes X and Y, respectively). Surface of table moving part carries rigging for installation and positioning of article being checked. Laser radiation source coupled optically to radiation receiver is fixed above operating space of table. Photodiode may be used as radiation receiver. Radiation receiver is positioned on immovable part of table 1 under its moving part. Output of radiation receiver is connected to inputs of primary processing units and control unit. Second inputs of primary processing units are connected to linear motion pickups, and outputs are connected to processor unit. The latter is connected to storage unit and interface unit, which output serves as control unit output and is connected to computer. Rigging for installation of article to be checked is represented by two parallel runners of triangular section which longitudinal axis is parallel to axis Y. Operating space of table moving part is made transparent for optical coupling of radiation source and radiation receiver. Rigging for positioning article to be checked is essentially dividing head made as a disc with holes arranged over circumference. Spring-loaded secured rigidly on table surface is coupled functionally to dividing head through holes. EFFECT: wide functional capabilities, quick action. 4 cl, 2 dwg
