ABSTRACT:
Riveting apparatus is shown to comprise a riveting spindle mounted for vertical reciprocating movement in a frame under the influence of a cam controlled lever and a reacting spring means. A motor in driving relation to a rotary shaft embodied in the spindle operates a wobble type riveting tool. Depending on the embodiment the same or a separate motor functions to drive a cam device, through the medium of which the lever is uniformly and periodically cycled to produce a vertical movement of the spindle which carries the riveting tool to and from an underlying work piece. One end of the lever is connected with the spindle while the other is pivotally anchored to the projected extremity of the piston rod of an air cylinder. The latter may be set to fix the operative position of the projected extremity of the piston rod and thereby the pivot point of the lever. It serves also to accommodate the shock of an excess riveting load and to enable a simple, safe and sure adjustment of the pivot point of the lever as and when required.
