Definitions

  • the present invention relates to a chuck for clamping a ball track milling cutter.
  • Chucks or tool chucks are known in the prior art, can be clamped by the tools, such as ball track milling cutters in a machine tool.
  • a chuck for chucking a ball race milling cutter comprising: a worm gear having a worm wheel and a worm, the chuck comprising a sleeve having a first internal thread, the sleeve being axially movable by rotational movement of the worm wheel, wherein in the first internal thread, a first external thread of the ball race cutter is arranged engageable.
  • a sleeve is provided within a chuck into which a ball raceway milling cutter can be screwed, whereby the sleeve can be designed to be axially movable by means of a worm gear.
  • this ensures that the thread that holds the ball track cutter and the thread that engages the worm wheel and is made possible by the axial movement for clamping, two different separate threads.
  • a chuck wherein the sleeve has a second external thread, wherein the second external thread is arranged engageable in a second internal thread of the worm wheel.
  • the connection between the sleeve and worm gear can be made via an external thread / internal thread connection, which can be achieved by a rotational movement of the worm wheel in a simple constructive manner, an axial displacement of the sleeve.
  • a chuck is provided, wherein the second external thread is arranged opposite to the first internal thread.
  • An arrangement of the first internal thread relative to the second external thread allows an extension of the chuck with a slender front portion, whereby the ball raceway milling cutter can mill even deeper ball tracks.
  • a chuck is provided, wherein the chuck has a stop for the ball raceway milling cutter.
  • a chuck is provided, wherein the chuck has a stop for the sleeve.
  • a stop for the sleeve can prevent too deep retraction of the sleeve in the chuck, whereby jamming can be excluded.
  • a chuck is provided, wherein the screw has an inner profile, such as a hexagon socket, and / or wherein the inner profile is accessible from the outside.
  • the arrangement of an inner profile, such as a hexagon socket can be achieved in a simple manner, for example by a socket wrench or a wrench, driving the worm gear, whereby a clamping and unclamping a tool, such as a ball mill, can be made possible.
  • a chuck is provided, wherein the chuck has an HSK interface or a steep taper interface.
  • the arrangement of a hollow shaft cone interface or a steep taper interface allows a mechanically stable insertion of the chuck into a corresponding machine tool.
  • a chuck is provided, wherein the chuck has an inner cone for receiving a conical portion of the ball raceway milling cutter.
  • a tapered portion of the chuck for receiving a tapered portion of the ball race cutter allows centering of the ball race cutter in the respective chuck.
  • a chuck with a sleeve available wherein the sleeve is formed axially displaceable by a worm gear and the releasably mechanically connected to a ball race, for example screwed, can be.
  • a thread of the sleeve can be used for axial movement of the sleeve.
  • the chuck has a worm gear for clamping and unclamping a ball race with a worm wheel 1 1 1, which can be driven by a worm wheel 1 13.
  • the worm wheel 1 13 may for example comprise a hexagon socket, in which a wrench can engage.
  • the worm wheel 1 1 1 can be rotated about its longitudinal axis from the outside, whereby the sleeve 103 can be moved axially, ie along its longitudinal axis 121, via an internal thread / external thread connection. Due to the axial movement of the sleeve 103, a chuck can be inserted into the chuck. set ball track milling cutters are clamped, if the sleeve 103 is moved in the direction of the HSK interface 1 15. If the sleeve 103 is moved away from the HSK interface 15, the ball track milling cutter can be stretched out.
  • the unclamped state of the ball raceway milling cutter can be unscrewed, ie the external thread 105 is screwed out of the sleeve 103 and a tool change can be made.
  • a clamping operation is carried out by inserting the ball race into the chuck, the ball race is screwed into the sleeve 103.
  • the worm wheel 1 1 1 is brought to rotate about its longitudinal axis and the sleeve 103 can be moved, for example, to HSK interface 1 15, whereby the Kugelbahnfräser also HSK - Interface 1 15 is moved and can be brought to rest on the receptacle 106 at the position 1 16, whereby the Kugelbahnfräser is clamped.
  • HSK interface 1 15 HSK interface 1 15
  • the Kugelbahnfräser also HSK - Interface 1 15 is moved and can be brought to rest on the receptacle 106 at the position 1 16, whereby the Kugelbahnfräser is clamped.
  • it can be prevented by the inventive clamping principle that only a few or only individual threads are engaged by an operator error between sleeve 103 and worm wheel 1 1 1. A breaking out of the sleeve 103 from the worm wheel 11 can therefore be reliably prevented.
