Definitions

  • the invention relates to an axial thread rolling head according to claim 1.
  • Axialgewinderollkexcellent are known for example from DE 12 69 086 or DE 24 38 937 C3 become. You usually see three offset by 120 ° to each other Profile rollers before, which are rotatably mounted in a so-called storage unit.
  • the Bearing unit is held by a shaft which is clamped in a machine tool becomes.
  • the thread rolling head is held in the direction of rotation, can but move it axially.
  • the rolling head is pressed onto the rotating workpiece, wherein the feed by the axially freely movable rolling head in the shaping of the Thread is done. After completion of the thread forming is required, the profile rollers disengage with the workpiece.
  • the profile rollers for certain workpiece diameter and Thread designed. If in the same machine tool another workpiece machining must be made, of course, another thread rolling head be used. This also applies to the case that the clamping section of the Shank is to be adapted to the special machine tool.
  • the shaft is in the state The technology component of the thread rolling head and can not be easily removed when the rolling head is not disassembled.
  • the invention has for its object to provide an axial thread rolling head, in the case of a multiplicity of thread rolling heads to be kept, the production outlay can be reduced.
  • axial thread rolling head In the axial thread rolling head according to the invention are clamping portion of Shank on the one hand and coupling section, bearing section and driver section the shaft on the other hand separate parts, via suitable connecting portion axially and rotationally fixed, but releasably connected to each other.
  • the corresponding shaft section by a be replaced easily with the other connected to the storage unit Part can remain in this.
  • the clamping portion may remain in the machine tool when the Removed storage unit and replaced by another desired. If in the machine tool only one thread rolling head is used, is for a Variety of different rolling heads only a single clamping shaft required.
  • the separate parts of the shaft firmly to connect with each other.
  • An embodiment of the invention provides for this purpose that the chucking portion has an axial cylindrical collar fitting in a coaxial cylindrical recess of the coupling portion is insertable, wherein a rear-side radial annular surface of the coupling portion against a radial abutment surface of the Einspannabitess rests.
  • the coupling section has radial circumferentially spaced bores in the cylindrical Lead recess and record the mounting screws.
  • the axial Bund has radial threaded holes for receiving the threaded portion of the Mounting screws. To separate the described parts therefore only need the fixing screws are released, of which e.g. three are provided.
  • the radial surfaces which lie against each other are precisely worked and determine the axial length of the shaft, for which a certain degree is maintained got to.
  • the holes and the Fixing screws designed so that when screwing in the mounting screws the radial annular surface and the radial abutment surface against each other be tense.
  • the in Figs. 1 to 3 illustrated shaft is composed of a first part 10 and a second part 12 together.
  • the part 10 has an elongated cylindrical Clamping portion 14 which is pierced axially in a known manner. He serves for Clamping in a suitable machine tool, wherein the axial perforation can receive a stop against which the workpiece abuts to move apart of bearing unit on the one hand and shank on the other.
  • a radial flange 16 is formed, which is a radial stop surface 18 forms.
  • the threaded holes 22 fastening screws 24, whose head is conical, as seen at 26.
  • the described portions of the part 10 are integrally formed.
  • the part 12 has a hollow cylindrical portion 30, which with radial through holes 32 is provided.
  • the through holes 32 are arranged at 90 ° spacing and have a conical countersink 34.
  • the conical countersink 34 eccentric.
  • the section 30 points to the part 10 opposite side on a coupling portion 36, here as a jaw coupling portion is trained.
  • the jaw coupling portion 36 cooperates a complementary coupling portion of the bearing unit of the axial thread rolling head together. Bearing unit on the one hand and the shaft according to FIGS. 1 to 3 On the other hand, relative to each other axially movable to the coupling portions in or disengage.
  • the bearing unit is received by a bearing section 38, which connects to the coupling portion 36.
  • a splined portion 40 which, as also known, with a complementary through hole of a central gear rotatably cooperates, in turn with pinions on the eccentric shafts for the profile rollers of the Axial thread rolling head combs.
  • the part 12 is also one piece.
  • the inner recess 42 of the section 30 fits snugly on the collar 20 and the axes of the holes 32 coincide with the axes of the threaded holes 22.
  • the mounting screws 24 screwed through the holes 32 in the threaded holes 22.
  • the Countersinks 34 with which the conical heads cooperate, eccentric are formed by the formation of the countersinks 34 an axial force component generated between the parts 10 and 12, whereby a rear annular surface 44 of the Section 30 is tightened against the stop surface 18 of the flange 16.
  • the part 12 is normally fixedly mounted in the axial thread rolling head, not shown. If another roll head is to be used or another chuck section, only a loosening of the mounting screws 24 is required, to take the pieces apart.
