ABSTRACT:
A method for providing a lateral bearing for the lower end of a drill quill which is mounted for plunging axial movement for drilling within a driver of a riveting machine, likewise mounted for axial movement. The method includes the steps of radially bearing the quill in a radial bearing and supporting the radial bearing in a cylindrical bearing support member having an axial bore which receives the radial bearing. The bearing support member is mounted on a bottom plate and laterally stabilizes the end of the drill quill for drilling precision. The drill quill is coaxially mounted within the rivet driver which also moves vertically, parallel to the plunging direction of the drill quill, to upset rivets. The driver is formed in segments in its midsection which extend through slots in the top of the quill bearing support member, and the bearing has a top flange that projects beyond the inner edge of the slots to provide a bearing surface for the inside of the segmented driver where it extends through the slots.
