  • Patent number: 11964114
    Abstract: An apparatus includes a body, a shaft assembly, and a deflection actuation assembly. The shaft defines a longitudinal axis and includes a flexible distal portion. The deflection actuation assembly includes a first rotary actuator, a translatable actuation member, and a resilient member. The translatable actuation member extends through the shaft assembly and is operatively coupled with the first rotary actuator and the flexible distal portion of the shaft assembly. The first rotary actuator is rotatable by a rotational force to thereby drive the translatable actuation member longitudinally. The resilient member is positioned between the first rotary actuator and the body and is configured to apply a friction force between the first rotary actuator and the body. The friction force is operable to increase the rotational force required to rotate the first rotary actuator.

    Abstract: A tool-holding system for centering a cutting tool to be utilized by a machine is disclosed herein. The tool-holding system includes a housing defining a tapered recess to be provided to the machine for receiving at least a portion of the tool, a first alignment portion provided to the housing, and an adaptor including a tapered shank that is to be received within the tapered recess defined by the housing. The adaptor includes an aperture formed in the adaptor for receiving a proximate end of the tool and a tool fastener for securing the proximate end of the tool within the aperture at a predetermined angular orientation therein. A second alignment portion is provided to the adaptor to cooperate with the first alignment portion to establish a predetermined angular orientation of the adaptor relative to the housing while the shank of the adaptor is at least partially inserted into the tapered recess. A fastener is also provided for securing the adaptor within the tapered recess of the housing.

  • Patent number: 8061718
    Abstract: A bit holder for a rotary tool is disclosed herein. In one embodiment, the bit holder comprises a drive shaft with an elongated bit channel configured to receive a tool bit for the rotary tool. A cavity is provided in a peripheral wall of the drive shaft. The cavity extends in a radial direction from the bit channel to an outer portion of the drive shaft. A moveable lock member is positioned in the cavity of the drive shaft. A collet is positioned in the bit channel apart from the cavity. The collet includes a collapsible end portion configured to clamp down on the tool bit. A collet nut rotatably engages the drive shaft and is moveable between a release position and a lock position. In the lock position the collet nut clamps the collapsible end portion of the collet while also forcing the lock member into the bit cavity.

  • Patent number: 8029216
    Abstract: A chuck and an article are configured such that the article is releasably secured in the chuck. One of the chuck and article is provided with a crest and the other with a trough. When the article is secured to the chuck, the crest enters the trough so as help prevent slippage of one with respect to the other. The chuck may include a receiver having a tapered bore, a collet having a complementarily tapered outer surface, and a nut configured to be threadingly secured to a forward end of the receiver; the article may be a shank, such as a tool shank. An inner surface of the collet may be provided with a crest which is configured to fit into a trough formed on the shank. In a secured position, the shank is accommodated in the bore of the collect with the crest of the collet at least partially occupying the trough of the shank, thereby preventing movement of the shank relative to the collet, which itself is accommodated in the bore of the receiver.

  • Patent number: 7669308
    Abstract: An collet and lock nut assembly includes a collet for receiving a cutting tool shank and a lock nut for creating a gripping force between the collet and the shank. The collet has a nose portion and a body portion separated by an annular groove. The lock nut has a plurality of retention tabs and a corresponding number of clear portions. The collet and lock nut assembly can be easily assembled by inserting at least one retention tab within the groove of the collet, and then applying pressure to the collet such that the remaining retention tabs of the lock nut are received within the groove of the collet to place the assembly in a locked position. The collet and cutting tool shank can be drawn from the tool holder by applying rotational torque to the lock nut. The collet is easily removed from the lock nut by applying pressure in any circumferential, lateral direction against the collet.

  • Publication number: 20090278324
    Abstract: A tool chucking apparatus to hold a machining cutter or tool includes a holding member and a fastening member that are coupled together to form a grip space inside to hold a collet. The collet has a plurality of pawl structures with a plurality of elastic slots formed thereon. When the holding member and the fastening member are coupled, the collet has one end tightly held in the holding member and the other end tightly held in the fastening member. Hence the two ends of the collet contract the elastic slots to tightly grip the cutter or tool. As a result, machining precision improves, safety enhances and the life span of the cutter or tool increases.

  • Patent number: 7549953
    Abstract: A quick-change tool-holding method and system for securing a tool within a primary tapered recess is disclosed. The tool-holding system includes an adaptor having a tapered exterior that closely approximates interior dimensions of the tapered recess to fit snugly within the tapered recess. The adaptor defines a secondary interior tapered recess and includes an exterior threaded portion about an aperture leading into the secondary tapered recess. A threaded fastener is also provided to include a threaded portion that is cooperable with threads provided adjacent to the primary tapered recess to secure the adaptor therein, as well as an aperture through which at least a portion of the exterior threaded portion of the adaptor extends when the adaptor is secured within the primary tapered recess by the threaded fastener. A collet comprising a plurality of slits formed therein is provided to allow the collet to elastically deform and constrict the tool when placed within an internal passage defined by the collet.

  • Patent number: 7506876
    Abstract: A quick-change system for changing a collet or bit on a tool has a base member to be attached to the body of the tool, an input member to be selectively latched to or unlatched from the tool body, an output member coupled to the input member via a torque multiplication device and having splines that are engageable and disengageable with a collet nut for the tool having a splined member when the two parts are moved relative to each other a given axial distance. When the input member is latched to the tool's body, the output member and the collet nut are disengaged so as to allow the collet nut to rotate with the tool's spindle during operation of the tool. When the input member is unlatched from the tool's body, it can rotate freely and is spring biased to cause the collet nut and output member to move into engagement such that torquing the input member loosens or tightens the collet nut to release or clamp the bit, respectively.
