Abstract: A bolt for the detachable connection of two component parts provided with at least one through-hole and a clamping system serving for detachably, rapidly and reliably interconnecting objects provided with through-holes. A plug-in pin includes a bolt housing having through-openings; a clip means supported in the through-openings; and a clamping device arranged in the housing's interior and provided with an external thread, which meshes with an internal thread of the housing and during clamping, forces the clip means out of the housing such that an outer portion of the clip means protrudes from the through-openings. The clip means is made at least as one sliding element supported in the bolt housing in a rotationally fixed fashion and the sliding element's outer portion has a support surface in the form of a lateral area segment of a truncated cone or an annular support surface.

Abstract: The invention relates to a clamping device, in particular for clamping a workpiece, comprising a support body 10 including a clamping member 20 for applying an axial force at a longitudinal end thereof and a limiting member 30 substantially in the region of the opposite longitudinal end of the support body 10, and at least one expansion region 40, 50. In this arrangement, a ball clamping set 60, 70 is arranged in each case in the at least one expansion region 40, 50, the at least one ball clamping set 60, 70 including at least one first ball 80 having a first diameter and at least two second balls 90, 95 having a second diameter, the first diameter being larger than the second diameter and the at least one ball clamping set 60, 70 cooperating with the clamping member 20. In addition, the balls 80, 90, 95 of the ball clamping set 60, 70 are in contact so as to convert the axial force of the clamping member 20 by means of the ball clamping set 60, 70 into a radial force which acts towards the support body 10.

Abstract: A table, particularly an orienting and welding table comprises a table plate having a surface provided with uniformly distributed cylindrical throughgoing openings arranged in a grid with a uniform distance therebetween.
