ABSTRACT:
A device for aligning and measuring a hollow, rotatable bore includes a laser beam source within a housing having an aperture in its front face for passing the beam. The housing is mounted at one end of the extruder bore to project the beam through the bore to be detected by a target at the opposite end. The diameters of the aperture and bore are concentric and the laser beam defines an axis that is alignable with the axis of rotation of the rotatable member, using target signals, by vertical and horizontal displacement with micrometers disposed on the rear face of the laser housing. Various arrangements for mounting the housing on the extruder are disclosed. The target includes a sensing cell in a housing mounted in an adapter with four balls disposed on its periphery 90.degree. apart. The housing orients the cell plane coincident with the plane of the four balls and the diameter at the four balls is dimensioned to exceed that of the bore to be measured so that the target member when tilted and inserted into the bore will jam into place at an angle. The four balls can be urged into contact with the inside diameter of the bore, resulting in a target that is self-centered. In another mode, the housing may be moved so that the cell plane is perpendicular to the axis of the bore to permit the diameter of the bore to be checked.
