279140000 | MEANS TO PREVENT JAW LOOSENING | 10 |
20100032910 | Spindle comprising a tension rod and a coupling device - The invention relates to a spindle, in particular a machine spindle, which is used to machine a work piece by means of a tool which is applied to the spindle, comprising an axially displaceable tension rod ( | 02-11-2010 |
20100066038 | Locking Chuck Jaws - A jaw for use in a drill chuck having a longitudinal center axis, comprising a chuck body which includes a jaw face formed on an inner surface of the chuck body and a plurality of teeth formed on an outer surface of the chuck body, the jaw face being substantially parallel to the longitudinal center axis. A ridge depends inwardly from the jaw face toward the longitudinal center axis. The ridge includes a tool engaging surface that is substantially parallel to the longitudinal center axis and has a width of between 0.020 to 0.060 inches. | 03-18-2010 |
20100213677 | KEY FOR QUICK CHANGE FOR TURRET POCKET - In an embodiment, there is a turret pocket key that includes a first slider block, a second slider block, a third slider block and a fourth slider block. The slider blocks are retained such that the slider blocks are adapted to move relative to one another, the key is adapted to move the first slider block and/or the fourth slider block to draw the first slider block and the fourth slider block relatively towards each other, and when the first slider block and the fourth slider block are drawn relatively towards each other, the second slider block and the third slider block move outward in a direction normal to the relative direction of movement of the first slider block towards the fourth slider block. | 08-26-2010 |
20120086177 | POWER TOOL HAVING A CLAMPING DEVICE FOR A WORKING ELEMENT - The present disclosure provides a power tool having a clamping device for a working element. The power tool includes an output shaft, a fastening piece having a flange portion for clamping the working element and a protruding shaft substantially perpendicular to the flange portion. A locking assembly comprising a locking member having a first position in which the protruding shaft is locked and a second position in which the protruding shaft is loosened is provided, wherein a pressing member can press the working element between the pressing member and the flange portion when the locking member is in the first position. The power tool can fasten the working element to the output shaft in a simple and reliable manner without the necessary use of such auxiliary tools as a spanner etc. and can achieve a stronger clamping force even under impact conditions. | 04-12-2012 |
20120139196 | POWER TOOL - A power tool has a driving shaft driving a working element, a fastening piece fastening the working element to the driving shaft having a projecting shaft insertable into the driving shaft, a locking assembly locking the projecting shaft in the driving shaft having a locking member wherein the locking member has a locking position for locking the projecting shaft with the driving shaft and a loosening position for loosening the projecting shaft with the driving shaft. At the locking position, the fastening piece is pressed towards an end portion of the driving shaft by an elastic component. The locking assembly further includes a movable member arranged outside of the driving shaft, the movable member having a first portion and a second portion which can be directly or indirectly mated with the locking member wherein a radial distance of the first portion relative to a shaft center of the driving shaft is unequal to that of the second portion relative to the shaft center of the driving shaft. | 06-07-2012 |
20130207353 | SELF TIGHTENING CHUCK WITH AN AXIAL LOCK - A chuck with a generally cylindrical body having a tail section configured to receive a drive shaft of a driver and a nose section having an axial bore formed therein. A plurality of jaws is movably disposed with respect to the body. A threaded spindle is rotatably connected to the body and operatively engages the jaws. A first ring is fixedly mounted about the body and has a first plurality of teeth. An inner sleeve is rotatably mounted about the tail section and has an open portion. A second ring that has at least one protrusion that mates with the corresponding open portion and extends outwardly from the inner sleeve and the ring has a second plurality of teeth. An outer sleeve is placed concentrically around the inner sleeve and contains a lock groove that the protrusion of the second ring is situated inside the lock groove. | 08-15-2013 |
20130228985 | TOOL LOCKING MECHANISM - A locking mechanism for use with a tool has a tool having a first working end, an opposite second end, a central axis therebetween, and a least one axial recess formed on an outer surface of the tool. A cap is rotatably received on the tool opposite second end, the cap comprising at least one recess formed on an outer surface thereon. The cap is rotatable between a first position in which the cap at least one recess aligns with the tool at least one recess, and a second position in which the cap at least one recess is out of alignment with the tool at least one recess. The locking mechanism further comprises a detent operatively positioned between the tool and the cap. The detent may be a pin and a spring, where the spring biases the cap into the second position. | 09-05-2013 |
20130292915 | RUNOFF SAFETY DEVICE - A runoff safety device is configured to prevent runoff of at least one of a chucking element and a tool from a spindle in a braking mode. The runoff safety device has at least one transfer unit and an imbalance compensating unit configured to at least reduce an imbalance of the transfer unit in a mode. | 11-07-2013 |
20150115554 | TOOL ATTACHMENT FOR A HAND-HELD MACHINE TOOL - In a tool attachment for fastening to a fastening interface of a hand-held machine tool, having a locking unit which in an unlocked state makes it possible for the tool attachment to be placed on the fastening interface of the hand-held machine tool and in a locked state makes it possible for the tool attachment to be locked to the fastening interface of the hand-held machine tool for operation, the locking unit having a rotatable locking body, and a first rotational position of the locking body being associated with the unlocked state and a second rotational position of the locking body being associated with the locked state, the locking unit has a locking member which is configured to prevent rotation of the locking body from the second rotational position into the first rotational position in the locked state. | 04-30-2015 |
