279133000 | WITH CENTERING MEANS | 11 |
20090014968 | Method and device for centering and clamping a workpiece in a balancing machine - The method includes the steps of positioning a workpiece ( | 01-15-2009 |
20130001900 | SETTING MECHANISM FOR A SETTABLE TOOL HOLDER ADAPTOR, AND TOOL ADAPTOR - A setting mechanism for a settable tool holder adapter includes a differential screw having two thread portions of differing pitch but identical direction of hand and a pressure piece having a pressure piece thread. One of the thread portions of the differential screw is screwed into the thread of the pressure piece. | 01-03-2013 |
20130075984 | SECURING DEVICE FOR SECURING A CHUCK ON A ROTATING SPINDLE - The invention concerns a securing device for securing a chuck, in particular a power-operated chuck, on a rotating spindle of a machine, wherein a rotating element and at least one chucking-slide assembly are provided in a main body in such a way that, when the rotating element turns, the chucking-slide assemblies change their radial position such that, in a chucking position, they force the chuck against the securing device in the axial direction. | 03-28-2013 |
20130093147 | METHOD AND DEVICE FOR CENTERING AND CLAMPING A WORKPIECE IN A BALANCING MACHINE - The chuck includes a centering clamping member having a variable diameter, a radially extending clamping surface, which is adjacent to the centering clamping member, a movable clamping element, a first spring element, via which the centering clamping member can be moved into a clamping position, a second spring element, via which the clamping element can be loaded with a first force, a third spring element, via which the clamping element can be loaded with a second, higher force, and an axially movable actuating device by which the centering clamping member and the clamping element can be moved into a release position against the force of the first and third spring elements. | 04-18-2013 |
20130119619 | TOOL HOLDER - The present invention relates to a tool holder that either has a modular design, and the modules of which are centered via interfaces, or/and in which a centered interface is provided between the tool and the tool receiver such that high concentricity, and thus a high processing accuracy are achieved. The present invention further relates to a system comprising a tool holder and a tool. | 05-16-2013 |
20140062039 | QUICK-CHANGE TOP TOOLING - A quick-change top tooling system is provided to accommodate various sized and configurations of workpieces to be chucked. The quick-change top tooling system includes a chuck body, at least one jaw assembly, and at least one workstop assembly. The jaw assembly comprises a master post fixed to a surface of the chuck body and a jaw releasably coupled to the master post. The workstop assembly comprises a workstop base mounted to the surface of the chuck body and a workstop releasably coupled to the workstop base. The at least one jaw and workstop may engage and clamp a workpiece to be chucked to maintain the concentricity and parallelism of the workpiece. | 03-06-2014 |
20140131958 | Tool Attachment For A Hand-Held Machine Tool - A tool attachment has: a mounting unit for mounting on a mounting interface of a hand-held machine tool; and a centering aid provided on the mounting unit for axially centering the mounting unit on the mounting interface. | 05-15-2014 |
20140191480 | RIM REPLACING DEVICE IN TIRE BALANCE MEASURING DEVICE - A lower side coupling of a Hirth coupling is coaxially coupled and fixed to a spindle, an upper side coupling of the Hirth coupling is coaxially coupled and fixed to a lower rim, the upper side coupling of the lower rim is meshed with the lower side coupling of the spindle, and upward separation of the lower rim from the spindle is prevented by chuck mechanisms. | 07-10-2014 |
20140197610 | SUBSTRATE GRIPPING APPARATUS - The present invention relates to a substrate gripping apparatus includes a base, a plurality of support posts which are vertically movable relative to the base, a lifting mechanism configured to lift the support posts, and a substrate holder and a substrate guide member mounted to each of the support posts. Each of the support posts includes a relative movement mechanism configured to move the substrate holder in such a direction that the substrate holder releases a peripheral portion of a substrate, while raising the substrate guide member relative to the substrate holder, when the support post moves upward, and to move the substrate holder in such a direction that the substrate holder grips the peripheral portion of the substrate, while lowering the substrate guide member relative to the substrate holder, when the support post moves downward. | 07-17-2014 |
20150115553 | Clamping Fixture - The invention relates to a clamping fixture comprising a chuck ( | 04-30-2015 |
