  • Patent number: 9022393
    Abstract: A cutting tool includes a chuck, a compressible conical collet and a lock nut for locking the collet. The cutting tool lock nut has a nut portion with a threaded portion for threading with the chuck, and a locking portion with a collet-locking surface formed with angled coolant grooves thereon. The collet-locking surface presses on the collet head, thereby compressing it to grip a tool shank in a collet bore thereof. As the locking portion presses only against a peripheral surface of the collet head, the lock nut is suitable for locking collets with different bore diameters. When the chuck is provided with a coolant fluid, the coolant fluid flows through the chuck and through the collet towards the locking portion, passing through the coolant notches between the locking portion and the collet head, and sprayed towards a location along the tool shank.

The collet is easily removed from the lock nut by applying pressure in any circumferential, lateral direction against the collet.

  • Patent number: 6945145
    Abstract: A quick action, cam operated hand tool holder, such as a tap wrench. The cam is moveable between at least one released and one locked positions, preferably by a conventional T-handle. A third position may also be provided which may be either a second locked or a second released position. An adjustable nut, or similar, retains a collet within the wrench and adjusts the wrench to different sizes of tools (i.e. taps) and adjusts the gripping force applied when the cam is locked. The collet is preferably reversible, accommodating different tool sizes on each end, but may also be single ended.

  • Patent number: 6932357
    Abstract: A gear reducing collet nut assembly is provided for holding a tool bit. The assembly includes an outer grip sleeve that can be rotated to actuate a clamping structure with a bore for holding a tool bit. More specifically, the assembly includes a planetary gear system to amplify torque from the grip sleeve to facilitate effective manual operation. The assembly includes a base member that is securable to a shaft of a rotary power tool, and the planetary gears are rotatably mounted at a plurality of positions on the base member. The planetary gears are driven by a central sun gear that is fixed to the grip sleeve. The planetary gears deliver torque to a ring gear that extends peripherally around the planetary gears. Movement of the ring gear is effective to actuate the clamping structure. In an embodiment, an exterior of the ring gear is threaded to the base member and axially fixed relative to the grip sleeve.

  • Patent number: 6913429
    Abstract: A bit retaining assembly for retaining a bit in a rotary tool, in particular a router such as a hand-held router, a table-mounted router, a pocket cutter, a laminate trimmer, a rotary cutout tool, or the like employs a planetary gear system for multiplying the torque applied to clamp the bit within a collet. The bit retaining assembly comprises a chuck for coupling the bit retaining assembly to the rotor shaft of the rotary tool. A collet is disposed in the chuck for receiving the bit. A nut threaded onto the chuck compresses the collet about the bit to secure the bit within the collet. A planetary gear system transmits torque applied to a housing member to the nut for rotating the nut on the chuck. Preferably, the planetary gear system multiplies the torque transmitted to the nut so that the torque transmitted to the nut is greater than the torque applied to the housing member.

  • Patent number: 6886835
    Abstract: The present invention enhances the lubricating property of the sliding surfaces of a clamp nut and a collet, reduces a friction coefficient, prevents the occurrence of seizure, and enhances durability. Accordingly, it is possible to rotate the clamp nut and the collet without causing vibrations due to imbalance. Moreover, this invention provides a clamp nut that can maintain tool-mounting accuracy for a long period of time even in the case of high-speed rotation, and also provides a collet chuck including such clamp nut. Concerning the clamp nut which is mounted on a collet chuck body for holding tools in the collet and which clamps the collet chuck body and the collet together, at least a part of the clamp nut which comes in contact with the collet is made of oil-bearing metal.

  • Patent number: 6860889
    Abstract: A tool for gripping and removing mechanical fasteners such as pedicle screws. With reference to FIG. 7, the device generally resembles a screwdriver, having a handle on one end, a long shaft in the middle, and fastener engaging means on the other end. The fastener engaging means comprises a set of two or more jaws having inward facing gripping surfaces positioned to grasp the external surfaces of a screw head. The jaws are formed as part of a collet slidably mounted within an outer thread sleeve. The thread sleeve is attached to the shaft. A tapered journal on the collet interacts with a tapered bore in the thread sleeve so that when the collet is pulled into the thread sleeve, the set of two or more jaws are squeezed together. The threaded engagements between the collet and the thread sleeve should be the reverse of the thread on the screw to be removed; i.e., if a right-hand screw is to be removed then the threaded engagement between the collet and the thread sleeve should be made with a left-hand thread.

  • Publication number: 20040130105
    Abstract: A chuck for securing a cutter with a faceted end on a machine includes a body with a head, a retainer, a plug and a positioning device. The head has a tapered periphery, an external thread and a passage defined axially in the head. Three slots are defined radially through the head to divide the head into three clamping members. A tapered hole and a through hole with an internal thread are adjacently defined in the retainer. The cutter is inserted into the passage, and the plug is positioned in one of the slots to abut the faceted end of the cutter. As the retainer screws on the head tightly, the clamping members securely grip the cutter, and the plug holds the faceted end of the cutter in place so the cutter will not rotatably slip so accurate cuts can be made.

  • Patent number: 5938212
    Abstract: An adaptive holder for interconnecting a non-locking bit shaft in a locking bit chuck provides an elongate body having a locking bit shaft at a first end and a chuck connector at the second end. The locking bit shaft is of hexagonal cross-section with an annular fastening groove defined spacedly inward of its outer end. The body is formed of elastically resilient material. The chuck connector provides a second body end defining a hexagonal fastening channel and a threaded external surface operatively carrying an annular collet threaded from its inner end outwardly to a point spacedly distant from its outer end with plural imperfectly formed threads in its outer end portion to cause radially inward motion of the body second end to move along the imperfect threads to releasably fasten a non-locking bit in the channel. The second end portion of the body may define one or more slots extending through the body to the fastening channel to aid radial motion of the body to fasten a bit.

    Abstract: High speed machining of parts is greatly enhanced when the axial alignment between the machining tool, its tool holder assembly, and a tool driver assembly can be precisely maintained, preferably within about one ten thousandths of an inch, in order to achieve the utmost in machining precision in the parts being machined. In order to maintain this desired degree of alignment, the machining tool is mounted in an angularly adjustable holder assembly which mates with a complementary socket that forms a part of the tool driver assembly. The tool holder assembly can also be used to move the tool radially sideways in a rectilinear fashion relative to the tool driver assembly, if desired. The tool holder assembly, besides being able to adjust the alignment of the tool relative to the tool driver assembly, is also operative to securely clamp the tool to the tool driver assembly.
