Definitions

  • the present invention relates to a gear cutting machine, for example, a machine for milling threads, gears or screws according to the independent device claim and to a method for machining gear teeth on workpieces according to the independent method claim.
  • Gear machines are already known. However, the gearing process is relatively expensive, especially for gears with large modules, for longer threads or for gears with a large number of teeth, which must be individually gef rasst.
  • Eshausen Veriereungsmaschinen which have several independent Wälzf räser and / or thread mill to work on several workpieces at the same time.
  • Such machines also have multiple tool motors, and thus are usually bulky, expensive, and difficult to program.
  • the problem of lost dead times is not solved.
  • the other objective is to minimize the unproductive dead times during which no workpiece is machined, and to increase speed and productivity.
  • the flexibility is also to be increased while keeping the space and the price of the machine low, for example by reducing the number of drive motors.
  • the machine should preferably be CNC-controllable.
  • a milling cutter having a first axis of rotation for machining teeth
  • a first group having a first spindle and a counter holder for rotationally driving a first workpiece about a workpiece axis
  • a second group having a second spindle and an anvil for rotatably driving a second workpiece about the workpiece axis, guides parallel to the designated workpiece axis for alternatively shifting the named first group or group to a processing station where gears can be milled in the first or in the second workpiece from the named cutter.
  • Another advantage is that the number of components, especially expensive or bulky components, can remain low.
  • FIG. 1 is a schematic representation of a machine tool in a perspective view from the front, the machine being in a position for machining the workpiece with a hob.
  • FIG. 1 is a schematic representation of a machine tool in a perspective view from the front, the machine being in a position for machining the workpiece with a hob.
  • the illustrated gear machine 1 is a Wälzf milling machine with a cutter 3, which is rotatably driven by a motor 50 about the rotation axis Y1.
  • the inventive method can also be applied with a Gewindef räser, which rotates about the horizontal axis in the figure X.
  • both a non-illustrated threaded or Schneckenf räser, which operates approximately parallel to the workpiece, as well as a hob on a common module 5 is mounted between a first processing position and a second processing position to a can pivot any angle in a range to edit the same workpiece either or alternatively with the threaded and with the Wälzf räser.
  • the tool motor 50 is mounted on the module 5, which is pivotable about the axis Z, so that the entire length of the workpiece can be edited.
  • the axis Z is horizontal and orthogonal to the workpiece axis X.
  • the machine 1 comprises a first group of workpieces with a first workpiece 6 held between a first spindle 61 and a first counter-holder 62. Bn first workpiece motor 60, the first workpiece 6 rotate about the horizontal workpiece axis X.
  • the second group of workpieces is also present, which includes a second workpiece 7, a second spindle 71, a second counterholder 72 and a second workpiece motor 70.
  • the second group is arranged coaxially with the first group, but the direction of the spindle and counter-holder are opposite.
  • the second workpiece can be rotated by the second spindle about the workpiece axis X.
  • Both groups of workpieces are mounted on the same guide 53 on an inclined surface 10, and thus can be moved manually or preferably motor driven simultaneously linearly along the workpiece axis X. To keep the distance between the two groups, preferably the two groups only moved together; independent shifts are not possible. This also has the advantage that only a single actuator and a single command for the displacement of both groups are required.
  • the arrangement of both groups on an inclined surface 10 has, inter alia, the advantage that the base of the workpiece motors 60, 70 does not strike against the lower end of the hob 3 or against other parts on the module 5, in particular if the ends of the workpieces 6, 7 to be edited.
  • the processing space remains more easily accessible than if the base of the motors 60, 70 were mounted approximately vertically.
  • the first group is located at a first group
  • Loading or unloading station D at which the machined workpiece 6 unloaded and a new it workpiece can be loaded manually or automatically.
  • the second group is, however, at a processing station E, where the second workpiece 7 is machined by the Veryakungsf.
  • the loading and unloading of a workpiece at the station D preferably takes place during the processing at the station E.
  • both groups can be moved linearly along the guide 53 at the same time to bring the first workpiece 6 loaded to the processing station Ezu and to bring the workpiece 7 processed at the same time to the second loading station F, where it discharges and can be replaced.
  • the gear cutting machine can be combined with an automatic loading and unloading device that either provides one of the two charging stations or both stations.
  • Two independent loading and unloading devices can also be provided to supply the two processing stations independently.
  • the workpiece 6 can also move linearly in the direction X along the guide 53 relative to the module 5 during the milling process.
  • the two workpiece motors 60 and 70 are disposed at opposite ends of the guide 53 so that they do not butt against the module 5 and that the entire length of the workpieces 6, 7 can be machined by the miller 3.
  • the tool motor 50, the workpiece motor 60 and preferably also motors for linear displacement of the tool and / or the workpieces 6, 7 along the various guides are preferably controlled by a program in a CNC unit.
  • the CNC unit preferably operates the rotary drives and the linear drives synchronously, preferably at programmable speed and speed ratios, in order to be able to machine different types of gears and / or threads with the same machine.
  • the present invention is particularly, but not exclusively, suitable for machining threads and gears up to module 2.5.
  • Rotary axes X and Y1 in each machining position always in a vertical plane (neglecting the small horizontal distance along Z).
  • the tool motor 50 is thus never in a horizontal position orthogonal to the workpiece rotor 60, so that the depth of the machine 1 and the accessibility are improved.
  • the illustrated gear cutting machine has two charging stations and a processing station. Also possible are variants with more charging stations and / or more processing stations along one or more guides.
  • data carriers with a software program for carrying out the method which can be executed by data processing means in a milling machine (for example magnetic and / or optical media carriers), can also be marketed.
