Embodiment Construction

[0027] figure 1 Illustrated generally at 10 for clamping uneven workpieces 12 (see figure 2 ), wherein the clamping device 10 has a central suction device 14 in the form of an air box suction device 16 . The suction device 14 is surrounded by a support device 18, which has a plurality of positioning pins 20, wherein the suction device 14 and the support device 18 are aligned in the same direction, referred to below as the axial direction. The suction device 14 and the support device 18 are fastened to a housing 22 which, for its part, can be mounted on a (not shown) robot arm.

[0028] figure 2 A side view of the clamping device 10 is shown, in which a workpiece 12 is both supported and clamped. as from figure 2 As can be clearly seen in FIG. 3 , the positioning pin 20 has a hemispherical top 24 which bears against the workpiece 12 . Furthermore, the suction end of the gas box suction device 16 rests against the workpiece 12 , wherein the highly flexible gas box suctio...

Abstract

The device (10) has suction device (14) which sucks work piece to be clamped. A supporting device is provided with a cylinder forming housing (22). The cylinder and housing are provided on three axially projecting and axially movable positioning pins (20). A piston is arranged in cylinder, and axially moved adjacent to pins. A clamping sleeve is engaged on pin to engage jacket of piston directly or indirectly in clamping position of piston, and to exert radial force on pin, so that pin in housing is displaced radially, and axially clamped.

Description

technical field [0001] The invention relates to a clamping device having a support device and a suction device for suctioning a workpiece to be clamped. Background technique [0002] Such a clamping device is known from DE 10 2007 020 898 A1. Supporting devices are known, for example, from US 2009 / 0309284 A1, DE 10 2005 050 649 A1, DE 198 10 478 B4, DE 10 2005 022 887 A1 or DE 41 35 490 C1. Another such clamping device is known, for example, from DE 10 2005 050 649 A1. The clamping device has a suction space for sucking workpieces to be clamped, wherein a total of four positioning pins are arranged in the suction space, protruding more or less far from the suction space. A further embodiment envisages that the suction device is designed as a gas box suction, which is surrounded by four positioning pins. These positioning pins are sunk into the housing and can move axially in the housing. Screws acting radially on the positioning pin, clamping bushes clamping the position...
