| 279134000 | SEPARATE CHUCK-ACTUATING POWER SOURCE | 9 |
| 20100308547 | POWER TOOL - A power tool, which includes a handle portion and a housing; a chuck disposed in front of the housing, and the chuck that is selectively operated in one of a working mode and a chucking mode. The power tool further includes a driving device which drives the chuck to axially move between a first position and a second position. The electric tool is in the working mode when the chuck is in the first position and is in the chucking mode when the chuck is in the second position | 12-09-2010 |
| 20110068546 | Clamping unit - A clamping unit ( | 03-24-2011 |
| 20110181005 | REMOTELY CONTROLLABLE ROTARY SWITCH ACTUATOR - A rotary actuator comprises a rotatable chuck assembly and an actuating mechanism. The chuck assembly may include a chuck housing movable between retracted and deployed positions. The chuck assembly may further include a pair of jaws pivotable between open and closed positions in correspondence to the retracted and deployed positions of the chuck housing. The actuating mechanism may be coupled to the chuck assembly for rotation between “Off”, “Neutral”, and/or “On” positions. | 07-28-2011 |
| 20120025476 | Tool Chuck with Sleeve and Clutch Mechanism To Remove Operator Variability - A tool chuck may include a chuck body defining a longitudinal axis. A sleeve may be mounted on the chuck body for movement between a first axial position and a second axial position. A clutch part provided on the sleeve. The clutch part may engage with a cooperating clutch part when the sleeve is in the second axial position. The clutch part may have a working surface that faces in a direction perpendicular to the longitudinal axis. | 02-02-2012 |
| 20120074658 | Power Tool with Integrated Bit Retention Device - A power tool having a housing, an electric motor disposed in the housing, and a spindle drivingly attached to the electric motor. The spindle includes a cavity adapted for receiving a bit therein and a window extending through the spindle in communication with the cavity. The power tool further has a retention device including a bit engaging member disposed within the housing and operable to extend through the window and retain a bit within the cavity. The power tool still further has an actuator operable by a user externally of the housing to disengage the bit engaging member from a bit received in the cavity and, finally, a mechanical interconnection system operably coupled between the actuator and the retention device to actuate the retention device in response to the actuator, wherein the mechanical interconnection is disposed within the housing. | 03-29-2012 |
| 20120326402 | MACHINE TOOL - The invention refers to a machine tool for the machining of one or more work pieces, wherein the work piece is held indirectly or directly by a clamping device in the machine tool on or at a non-rotary work piece table or a work piece table rotating around at least one axis. | 12-27-2012 |
| 20130154206 | CHUCK WHICH CAN BE COUPLED BY AUTOMATION - A chuck for clamping workpieces or tools in a clamping space with a clamping force (F). The chuck includes at least two chuck jaws movable in translation along one clamping plane (E) in the direction of and a gear train located at least largely within the chuck for transfer of a driving torque of a drive motor, which can be coupled to the gear train by coupling means of the gear train, to the chuck jaws for movement of the chuck jaws. The coupling means able to be coupled to a corresponding coupling connection of the drive motor. The movement from the maximum size of the clamping space to the minimum size of the clamping space is executed via the gear train from the drive motor. | 06-20-2013 |
| 20140117631 | CLAMPING DEVICE - A clamping device for machine tools with a power-operated chuck, the clamping jaws of which are actuatable by the clamping device via a movement converter and draw rod. A drive motor is provided with a switching element which is adjustable by axial control in a middle and two limit positions, wherein the switching element is connectable to the clamping device in one limit position and, in the other limit position, to an adjustment element connectable to an auxiliary device. The switching element is lockable in the limit positions with a machine spindle. | 05-01-2014 |
| 279135000 | Self-contained | 1 |
| 20110095493 | PIEZOELECTRIC CLAMPING DEVICE - A clamping apparatus has been developed for coupling a tool member to the output shaft of a power tool without the use of auxiliary hands tools or a shaft-lock lever. The clamping apparatus includes a clamp member and a piezoelectric element. The clamp member is coupled to an output shaft of a motor. The piezoelectric element opposes the first clamp member and is configured to change from a first state to a second state in response to being coupled to a source of electrical energy. | 04-28-2011 |
