Definitions

  • the invention relates to a rod-like gear tool according to the preamble of claim 1.
  • the known rolling rods have lugs on the ends, with the help of which they are attachable to the carriage.
  • the height of the teeth is naturally predetermined and must always be observed. It goes without saying that after a certain time a wear of the teeth takes place. It is also known for the reprocessing of such worn rolling rods Sand down the residual profile and formulate a new profile. This gives the entire tooth profile a lower height. To this height It is known to compensate a so-called supplement between sled and To arrange rolling rod.
  • the disadvantage of such a solution is that they is only limited use, requires a difficult machine assembly and It can easily happen that the lugs or tabs at the ends of the Break rod.
  • the invention is based on the object of a toothing tool create the benefits of the latter solution without the main one Disadvantages. Despite the loss of logistics costs should at the same time the other expenses compared to conventional Devices are reduced.
  • the gear tool as per se known, in cross-section is approximately rectangular, on opposite Sides a toothing on. Further, on the other are opposite Side means provided for attachment in the machine tool.
  • the effort for the production of a rolling rod according to the invention is naturally slightly larger than for one which has only one tooth profile. On the other hand, it is significantly lower than for two separate rolling rods, in particular if the tooth profile on both sides of the invention Rolling rod is identical.
  • the service life corresponds, as I said, the double Life of conventional rolling rods, so that the elimination of a reprocessing, which in turn is associated with corresponding expenditure, is outweighed by the benefits.
  • Rolling rods of conventional type are known to be supported by their underside on a sled of the machine tool. This is with the double gearing the type described not possible. Therefore, according to the invention on the other sides of the rolling rod means provided to this safely set at a given height on a slide.
  • an embodiment of the invention provides that the means each have two oppositely directed abutment surfaces, the are formed on the sides of the rolling rod.
  • a tensioning device causes this Application of the contact surfaces on parallel spaced bearing surfaces. Further the clamping device has clamping means with which the contact surfaces pressed against the bearing surfaces.
  • the clamping means each have two oppositely directed clamping surfaces, on each side of the opposite other sides of the Has toothing tool, wherein the clamping surfaces associated with Contact surfaces form a spline.
  • the tensioning device has an elongated first clamping body, on which the bearing surfaces are formed and in which an elongate recess is formed above a bearing surface is, whose cross-section is complementary to the wedge-shaped profile.
  • the tensioning device has a second clamping body, which has an inclined surface having, with the facing clamping surface of the gear tool cooperates and means are provided to the second clamping body so pretension that the contact surfaces against the facing bearing surfaces be pressed.
  • the second clamping body has a second inclined surface, with the first inclined surface diverges outwards.
  • the second inclined surface works with a complementary inclined surface of the first clamping body together. It is provided at least one clamping screw, which is the second clamping body attracts against the first clamping body, creating a spline in the Complementary recess is pressed and the contact surfaces against the bearing surfaces are pressed to secure the gear tool in its restrained position.
  • the clamping bodies are preferably both integrally molded and extend at least over the length of the gear tool.
  • a rolling rod 10 is generally rectangular in cross-section and has on opposite sides a first toothing 12 and a second Toothing 14 on.
  • the serrations 12, 14 extend over the entire Length of the gear tool (rolling rod).
  • the profile toothing 12, 14 has different shape zones, namely one particular Inlet zone, a calibration zone and an outlet zone. In this order are the zones for the teeth 12 from right to left and for the Gearing 14 from left to right.
  • z For the production of a spindled Toothing, z.
  • two such rolling rods used by on a counter-rotating slide one not machine tool are clamped, where they are opposite Sides in the workpiece form a toothing. Consequently, can the rolling rod 10 first with its tooth profile 12 and then with their tooth profile 14 are used when the first by wear is useless.
  • the roll bar 10 has at the other opposite Pages two parallel spaced strips 16, 18 and 20, 22nd
  • the strips 16, 20 have upwardly facing contact surfaces 24, 26th and the strips 18, 20 downwardly facing contact surfaces 28, 30. The latter lie on bearing surfaces 32 and 34 of a clamping body 36, on the next will be discussed below.
  • each bar provides 16 to 22 in Cross section of a spline dar.
  • the bars 16 to 22 are symmetrical to a transverse center plane of the rolling rod 10 and symmetrical to its longitudinal center plane.
  • the first clamping body 36 extending over the length of the rolling rod 10th extends is approximately U-shaped in cross section.
  • the left leg forms with its top the bearing surface 32, while the bearing surface 34 of a recess 42 is formed on the inside of the other Leg is shaped and complementary to the cross-sectional profile of the strips 16 to 22.
  • the position of the strips 16 to 22 is such that when an edition of Contact surfaces 24, 26 and 28, 30 on the bearing surfaces 32, 34 a distance given to the web of the U-profile. This bridge is very stable to Pressing forces that act to a great extent on the rolling rod 10, take.
  • a second clamping body 44 has a first inclined surface 46 and a second Inclined surface 48, which inclined surfaces 46, 48 away from each other diverge and are arranged so that they are complementary to one Bevel 16 of the swept bar and a further inclined surface 50 of the first clamping body 36.
  • the second clamping body 44 extends over the same length as the first clamping body 36, and with the aid of several clamping screws, one of which is shown at 52 in dashed lines, becomes the second Clamping body 44 laterally clamped against the first clamping body 36.
  • the associated strip 22 is pressed into the recess 30, wherein the abutment surface 30 is pressed firmly against the bearing surface 34.
  • the Contact surface 28 is pressed firmly against the bearing surface 32 and the rolling rod 10 laterally held by the inclined surfaces 46, 48.
  • the clamping body 44 removed and the roll bar 10 is rotated 180 ° about its vertical axis and clamped again in the manner described.
