Patent application number | Description | Published |
20080217872 | Clamping Device - The invention relates to a tensioning device, especially for machine tools, in which a deforming tensioning element acts on a clamping part with a clamping force which results from the deformation in order to fix or release a fixing element. | 09-11-2008 |
20090208272 | CLAMPING AND/OR BRAKING DEVICE - The invention relates to a clamping and/or braking device, in particular a pneumatically actuatable clamping and/or braking device, with a housing having a space in which a hydraulic medium constructed least in part as a solid body is accommodated, wherein the space for accommodating the hydraulic medium is delimited on one side by a wall of the housing and on the other by a clamping and/or braking element, and with at least one actuating element that acts on the hydraulic medium to produce a clamping and/or braking force which can be transmitted by the clamping and/or braking element to an impinging element. According to the invention, at least one actuating element is shaped like a pin or a spike. The actuating element is movable along a predetermined spatial curve, and acts on the hydraulic medium through an aperture in the wall of the housing delimiting the space for accommodating the hydraulic medium. | 08-20-2009 |
20120186393 | WORKPIECE BRACKET - The invention concerns a workpiece console | 07-26-2012 |
20130181386 | PNEUMATIC COUPLING MODULE, IN PARTICULAR FOR A ZERO-POINT CLAMPING SYSTEM FOR A MACHINE TOOL - The invention relates to a pneumatic coupling module, in particular for a zero-point clamping system, with a least one pneumatically operable coupling device, to which the pneumatic medium can be fed via a supply channel and which is constructed in such a manner that the coupling device occupies a release position in its pressurized state and a locked position in its non-pressurized state, wherein the coupling module comprises an interface area for coupling another pneumatic coupling module or a pneumatically operable working module. According to the invention, a directional valve is provided in the supply channel, comprising a first port, which is connected to a first part of the supply channel, which feeds the pneumatic medium, a second port, which is connected to a second part of the supply channel, which leads from the directional valve to the coupling device, and a third port, which is connected to a supply coupling channel, the at least one outlet opening of which is arranged in the interface area in such a manner that the outlet opening can be coupled in a substantially sealed manner to at least one inlet opening of a supply channel or a manifold supply channel of an additional pneumatic coupling module or pneumatically operated working device, wherein the directional valve connects the first and the second ports in a first switching position (“INTERNAL”) in such a manner that the first and second parts of the supply channel are connected and the coupling device is controlled to assume its release position and wherein the directional valve disconnects the first port from the third port in the first switching position, whereby no pneumatic medium can be fed to the supply coupling channel, and wherein the directional valve disconnects the second port from the first port in a second switching position (“EXTERNAL”) and connects the first and third ports in such a manner that the first part of the supply channel is connected to the supply coupling channel and pneumatic medium can be fed to the supply coupling channel and that no pneumatic medium can be fed via the second part of the supply channel to the coupling device and it is controlled to assume the locked position. The invention further pertains to a modular clamping position consisting of such coupling modules. | 07-18-2013 |
20130234382 | CLAMPING SYSTEM - The invention concerns a clamping system for the clamping of workpieces, wherein clamping means can be moved by a small spacing relative to a stationary affixing block, so as to be able to clamp a workpiece independently of a fastening grid prespecified on a machine tool or to compensate for a distance change between clamping components located on the workpiece, so that a zero point previously defined on the workpiece again coincides after a renewed clamping with clamping components whose distances were changed. | 09-12-2013 |
20130241129 | SAFETY CLAMPING DEVICE - The invention concerns a safety clamping system for the fastening of workpieces on machine tools, wherein, in addition to one clamping mechanism known from the state of the art, at least one positioning mechanism is also provided, which can pre-position the workpiece roughly before the affixing and move it into the final affixing position and, at the same time, can facilitate the monitoring for an undesired detachment of the workpiece. | 09-19-2013 |
20140353898 | CLAMPING DEVICE, PARTICULARLY A CLAMPING MODULE - A clamping device includes a base part, a clamping element arranged such that it can be displaced relative to the base part in order to transmit a clamping force onto a part to be clamped, and a drive unit that displaceably impinges upon the clamping element. The drive unit has a threaded spindle or a threaded sleeve that can be driven rotationally by a motor to directly or indirectly cooperate with a corresponding part of the clamping element in such a manner that rotationally driving the threaded spindle or threaded sleeve effects a displacement of the clamping element and/or a generation of a clamping force. | 12-04-2014 |
