ABSTRACT:
Apparatus for precision assembly of photoreceptor drum having a thin-walled hollow tube and at least one end bell, includes an assembly fixture head having a drum collet for uniformly gripping an end of the hollow tube to true its cross-section; a means for defining the extreme distal end of the photoreceptor drum opposite the gripped tube end; an end bell collet for supporting the first end bell concentric with the gripped tube end; and a slidable cylindrical sleeve for selectively positioning the end bell a predetermined axial distance from the extreme distal end of the drum. Further, the apparatus is provided with a means for curing flowable adhesive which is applied between the end bell and the gripped tube end to securely fix the end bell concentric with the cross-section of the hollow tube at the uniform predetermined axial distance from the extreme distal end. The distal end defining means can include a second assembly fixture head for simultaneously mounting first and second end bells at respective ends of the drum, such that the end bells are concentrically secured to the hollow tube at the desired predetermined axial distance from each other.
