Abstract: A head unit for a stop holder for a drilling machine for purposes of compensating for a height displacement between two adjacent components during the introduction and/or machining of a component hole. The stop holder has a front rest section for purposes of resting on the components. The rest section has an axial projection, which forms a second contact surface displaced relative to a first contact surface in the axial direction, i.e., the tool longitudinal direction. Also disclosed is a stop holder, and a method for compensating for a height displacement between two adjacent components during the introduction and/or machining of a component hole.

Abstract: A drilling-out aid device for assisting in drilling out a rivet, in particular a blind rivet, by a drilling tool, includes a proximal handle portion for handling the drilling-out aid device; a guide device for centrically guiding a drilling shaft of the drilling tool; a distal rivet-head receiving device for centrically orientating the drilling-out aid device on the head of the rivet to be drilled out; and a rivet-head pressing device, which is mounted displaceably in the longitudinal direction of the drilling-out aid device relative to the rivet-head receiving device to apply a centric gripping force to the head of the rivet to be drilled out.

Abstract: A fastening device includes a fastening needle system, which is guided in a base body of the fastening device. The fastening needle system is configured to be led through a drilling hole of one or more components. By exercising a pulling force onto the fastening needle system, the components can be fastened between the front portion of the fastening needle and the base body. A fastening system may include the fastening device and a fastening pliers.

Abstract: An automatic riveting machine produces squeezed precision rivet connections in any working direction, including an overhead working direction, while using rivets of different lengths. A rivet bore having a precision fit and linear squeezing motions result in a precision rivet connection. The rivets are also pressed into the rivet bore by a linear motion. For this purpose, the automatic riveting machine includes a drilling unit (2) with a drill bit (212), a lubricator (204), a rivet supply unit (3) including a rivet feeder pipe (302) and rivet transfer tongs (302) journalled to a journal axis (304), and a squeezing rivet setter (4). The rivet transfer unit (3) is held in a fixed position on a support console (5) which in turn is docked to a positioning robot PR. The drilling unit (2) and the rivet setter (4) are movable along the support console (5) on guides for positioning in a working position or in a back rest position.
