Definitions

  • the present invention relates to a quick release chuck utilized for holding power bits or tools to a machine tool, and more particularly to a quick release chuck which is configurable with a drive spindle and which contains locking mechanisms for locking a tool shank radially and axially.
  • any collet or chuck device utilized for holding a power bit, for example a router bit, to a drive spindle must lock the power bit both axially and radially with respect to the drive spindle.
  • the power bit cannot rotate relative to the drive spindle nor be moved axially in and out relative thereto. This concern is especially important with high speed machine tools both for accuracy considerations and safety.
  • one relatively simple means for rotationally securing the tool bit consist of defining a hexagonal or other multi-sided profile on the end of the tool bit which fits into a corresponding multi-sided recess formed in the chuck device.
  • collet chucks utilize a compressible collet for axially and rotationally holding the tool bit.
  • Collet chucks are useful in that they do not depend on a multi- sided configuration in the tool bit for holding the tool. Thus, any manner of power bits or tool bits having essentially round shank portions may be held by a collet chuck device.
  • collet chuck devices do not have the quick-change or quick-release capabilities that are desired in many applications. For example, it is highly desirable for portable tools such as routers or laminate trimmers to utilize quick release chuck devices for relatively quick and easy changeout of tool bits.
  • the tool shank portions must be multi-sided to fit within corresponding bores defined in the quick-change chuck devices.
  • spindle of a machine tool wherein the shank portion of the tool bit need not be multi-sided.
  • a further object of the invention is to provide a versatile quick change chuck device which is capable of holding tool bits having round tool shanks.

  • This locking device is an axial movement locking device in that it prevents the tool from being axially moved relative to the chuck device.
  • a rotational movement locking device is configured within the recess of the body member. This rotational movement locking device prevents rotation between the tool shank and the device.
  • This locking member defines a bore which is aligned with the body member recess for receiving the tool shank passing through the recess.
  • the rotational movement locking device comprises a plurality of spring loaded longitudinal bearing members disposed about the bore. These longitudinal bearing members extend radially and tangentially inward into the bore so as to contact the tool shank. The bearing members are spring loaded in a tangential and radially inward direction so as to rotationally lock the tool shank against rotation in at least one rotational direction.

  • the inner sleeve further comprises an outer sleeve section which is concentric about the body member.
  • the inner sleeve member is axially movable relative to the body member by an operator pulling back on the outer sleeve section.

  • Inner sleeve member 16 is axially movable relative to body member 12 in that it can be moved longitudinally within recess 14.
  • Inner sleeve member 16 also includes an internal passage 18 defined therethrough. Bore 18 is essentially concentric with recess 14.
  • An axial spring mechanism 20 is disposed between the inner sleeve member 16 and body member 12 so as to bias the inner sleeve member axially away from body member 12.

  • spring mechanism 20 can include any conventional biasing member, such as a spring washer 37, etc.
  • spring 36 rests against shoulder 19 defined in body member 12. The other end of spring 36 presses against the end face 21 of inner sleeve member 16. In this manner, spring 36 biases inner sleeve member 16 axially away from body member 12.
  • An axial movement locking device 22 is configured within inner sleeve member 16. Locking device 22 allows a tool shank 13 to be slid into internal passage 18 of inner sleeve member 16 when the inner sleeve member is moved axially towards body member 12.

  • Longitudinal bearing members 28 are directed tangentially inward by way of a slanted surface 31 cooperating with spring device 29. Accordingly, the greater the rotational torque applied to a tool shank held within bore 26 in a direction corresponding to the spring effect of springs 29, the tighter the tool shank is held against rotation within bore 26.

Alternatively, longitudinal bearing members 28 may come in a variety of size, or may comprise individual bearings disposed end to end. Additionally, the rotational movement locking device may be configured so that rotation of the shank is not permitted in either direction. With the one-way roller bearings, rotation of the shank is permitted in one direction. However, the roller bearings may be tangentially biased in both rotational directions so that the tool shank cannot rotate in either direction.

  • Device 10 also preferably includes a locking mechanism 44 which is operably disposed between inner sleeve member 16 and body member 12.
  • This locking member prevents undesired axial movement between the inner sleeve and the body member during operation of the device. Since axial movement of inner sleeve member 16 would unlock tool shank 13 and allow for the tool to be withdrawn, it is desired to lock inner sleeve member in position axially with respect to body member 12 when the device is in operation. For this reason, locking mechanism 44 is provided to axially lock the inner sleeve with respect to the body member.

In this manner, inner sleeve member 16 can no longer be axially pushed towards body member 12.
