Chuck Key Patents (Class 279/147)
  • Patent number: 11524342
    Abstract: A tool holder for collet chucks, wherein a clamping rotor for applying an axial force to a collet chuck is provided. The clamping rotor, including the two axial bearings of the clamping rotor, are accommodated in a tool holder main part, which is connected to a collet chuck receiving body that receives the collet chuck. In order to captively support the clamping rotor in the main part, a bearing seat element is screwed into the main part, said bearing seat element delimiting a receiving chamber for the clamping rotor towards the collet chuck receiving element. Thus, the clamping rotor is enclosed and held in the main part independently of the collet chuck receiving body. This creates new possibilities for the maintenance and adaptation of the tool holder under different conditions, and in particular the force flow emanating from the clamping rotor during a clamping process is kept away from the collet chuck receiving body, thereby improving the precision of the tool holder.

  • Patent number: 10226831
    Abstract: A tap holder includes a body extending along an axis and having a front end portion defining a front opening and an externally threaded portion. A gripping assembly includes a spring having first and second legs, a first jaw mounted to the first leg, and a second jaw mounted to the second leg. Each jaw has a tapered outer wall and an inner wall with the inner walls of the jaws facing each other. A sleeve has an internally threaded bore threadably received on the externally threaded portion of the body, and an inner tapered surface configured to abut the tapered outer walls of the first and second jaws. As the sleeve is rotated relative to the body, a distance between the first and second gripping surfaces may be adjusted for gripping a tap between the inner walls of the first and second jaws.

  • Patent number: 9527138
    Abstract: A clamping means in the type of an outer clamping means or an inner clamping means for fixed-clamping of work pieces, for the purpose of rotative processing. For achieving a radial displaceability of the clamping segments thereof, an inclined guide surface of a clamping sleeve or of a clamping mandrel with correspondingly inclined slide surfaces on the clamping segments are used. For the application of force into the clamping segments, at least one coupling element is provided on the housing or on the actuation member. The clamping element is axially fixed to the housing or to the actuation member and engages with at least one clamping segment axially in a form-fit manner in a coupling region between an in axial direction distal guide surface region of the guide surface and an in axial direction proximal guide surface region of the guide surface.

  • Patent number: 5800102
    Abstract: The present invention uses a collar that fits over a nose and a locking cylinder of a chuck of the drilling machine. The collar has a cutout section to accommodate the chuck key including the key gear when it is engaged with the beveled gear of the locking cylinder. The collar has a first bore of a first diameter with is slightly larger than the outer diameter of the nose to provide a tight fit between the collar and the nose of the chuck. A fastener is used to attach the collar to the nose of the chuck. A second bore has a second diameter to fit over at least the beveled gear of the locking cylinder. The second diameter is large enough to provide a clearance so that the locking cylinder is free to rotate within the collar. Turning the chuck key about a key axis opens or closes the jaws of the chuck to grip or release a bit placed along a drill axis of the drilling machine.

    Abstract: A drill chuck key includes a bevel gear that is connectable with a collar of a drill to tighten or loosen the jaws of the drill and a mechanism for operating that bevel gear as the key is moved. The mechanism permits the tightening or loosening operation to be carried out using the same movement of the key, and prevents over- or under- tightening of the drill jaws. One form of the mechanism includes a double pawl engaging ratchet wheels one of which has at least one trip dog thereon so that identical oscillating motion of the key will impart tightening to the drill jaws and can also loosen those jaws. Another form of the mechanism includes epicyclic gearing.
