Definitions

  • the invention relates to a device for reworking a steel edge of a ski with at least one grinding device of a motor driven, cup-shaped grinding wheel with transverse to the direction of rotation axis, arranged on a Anstellschlitten bearing block, one transverse to the feed direction and perpendicular to the axis of rotation the grinding wheel extending pendulum axis for the grinding device forms, with a guide for the Anstellschlitten which is rotatably mounted about an axis extending in the direction of feed in a transversely movable to the feed direction cross slide, and with an adjustment for the angular position of the guide of Anstellschlittens.
  • the optional processing of the side or the lower edge is by a Pivoting adjustment of the grinding device allows an axis extending in the feed direction, wherein a pivot stop determines the respective angular position of the grinding device and thus the angle of the steel edge in the side or bottom edge region. About an adjustment of these pivot stops the desired grinding angle can be set in the side and bottom edge area.
  • the grinding devices receiving Anstellschlitten are mounted on independently movable cross slide.
  • the guides for the Anstellschlitten the grinding devices in the cross slide are in turn pivotable about an axis extending in the feed direction between the stop-limited basic positions for selectively processing the lower and side edges, with the help of swing cylinders.
  • the cup-shaped grinding wheel is in each case set at the front side of the steel edge region to be ground at a predetermined angle, which determines the later edge angle of the machined steel edge and is maintained exactly over the ski length.
  • a predetermined angle which determines the later edge angle of the machined steel edge and is maintained exactly over the ski length.
  • the grinding wheels are mounted on guide plates which are adjustably mounted transversely to the longitudinal direction of the ski, by means of guide pins, of which the guide pins turned away from the ski are guided in a relative to the running surface of the ski around a ski longitudinal axis inclined backdrop while the engage the ski facing guide pins in parallel to the tread guides.
  • the invention is therefore based on the object, a device for reworking a steel edge of a ski of the type described in such a way that the steel edges can be ground so repeatable that arise for the particular requirements advantageous driving and guiding properties for the ski.
  • the invention solves this problem with the device according to claim 1, wherein the adjusting means for the angular position of the guide of the Anstellschlittens has an actuator, which is controlled by means of a control device in dependence on the ski length related position of the grinding engagement.
  • the actuator includes a controlled electric stepper motor with a low-backlash gear, which is connected to the guide for the Anstellschlitten.
  • a separate pivot drive is unnecessary to adjust the guide for the Anstellschlitten between the grinding positions for the lower and the side edge of the ski, because this conversion of the basic positions of the grinding device can be made via the actuator.
  • the alignment of the grinding device corresponding to the edge profile over the pendulum axis running perpendicular to the axis of rotation of the grinding wheel and transversely to the feed direction requires that the pot-like grinding wheel must be supported on the face side in the region of two peripheral sections on the steel edge of the ski which runs in a chordal manner with respect to the grinding wheel, resulting in the end regions of the ski Skis can lead to difficulties if the steel edge is to be machined into the end area while maintaining accurate grinding angle.
  • the grinding device can be rotatably connected to the bearing block via a locking device, so that for the machining of the ski ends, the grinding wheel can be used under a one-sided support on the steel edge to be ground.
  • a double-armed lever with two provided on both sides of the grinder guide rollers for the lateral longitudinal edges of the ski can be mounted on the cross slide, so that there is an independent concern of the guide rollers on the lateral longitudinal edges of the ski on the possible pendulum motion of the double-armed lever.
  • This support of the cross slide relative to the machined firmly held ski is only effective if both guide rollers rest against the ski.
  • a support via only one guide roller can be made possible, which is required in the end regions of the ski, the lever with the guide rollers in its respective pivot position by a locking device rotatably connected to the cross slide.
  • the control device for the change of the edge angle to be ground over the length of the ski offers the simple possibility of also controlling other grinding parameters as a function of the position of the grinding engagement related to the ski length.
  • the grinding pressure can be applied by a corresponding control of the Anstellzylinders for Anstellschlitten with different pressure and the rotational speed of the grinding wheel and / or the feed rate can be changed to take appropriate influence on the surface quality of the grinding surfaces, resulting in cooperation with a corresponding interpretation of Edge angle advantageous effect on the ski guiding and the maintenance of the ski on a hard or icy surface.
  • the respective control parameters for the grinding of the ski edge of the control device for determining the reference variables must be specified.
  • the control device may advantageously have an interface for inputting these control parameters.
  • a writing device for a preferably machine-readable identifier of the respective control parameters can be controlled via the control device, so that the carrier of this identifier attached to the ski, preferably glued, can be.
  • the respective control parameters for a repeated post-processing of the ski edges can be read automatically into the control device in order to be changed only in regions, if need be to improve the driving behavior.
  • the illustrated apparatus for processing the steel edges of a ski 1 has a in a non-illustrated housing on vertical guides 2 of the height displaceable frame 3, which can be adjusted via lifting cylinder along the guides 2.
  • guide rods 5 are provided for two cross slide 6, which are movable by means of on the one hand on the side cheeks 4 and on the other hand acting on the cross slide 6 actuating cylinders 7 along the guide rods 5.
  • guides 8 for Anstellschlitten 9 are rotatably mounted, namely about a direction of travel 10 of the ski 1 extending axis of rotation a, as indicated by dash-dotted lines in Figs. 1 and 2.
  • an actuating drive 11 which according to the embodiment of an electric stepper motor 12 and a low-backlash gear 13, preferably a bevel gear, consists, on the output shaft, the guide 8 rotatably seated.
  • the guided on guide rods 14 of the guide 8 Anstellschlitten 9 carries a bearing block 15 for a grinding device 16, which includes a motor 17 and a cup-shaped grinding wheel 18 and is rotatably supported in the bearing block 15 about a pendulum axis b, which is perpendicular to the axis of rotation of the cup-shaped grinding wheel 18 and is aligned transversely to the feed direction 10.
  • the grinder 16 can be rotatably connected to the bearing block 15 via a locking device 19, which is achieved in the embodiment by a locking cylinder between the bearing block 15 and the grinding device 16.
  • the ski 1 is machined on a merely in FIGS. 1 and 3 indicated by dash-dotted longitudinal carriage 20 machined on rubber-elastic supports 21 so that when lowering the frame 3 on the guides 2 in the frame 3 mounted hold-down rollers 22 touch down on the tread of the ski 1 and determine a reference plane for the processing of the steel edges, as can be seen in FIG. 2.
  • guide rollers 23 are provided in the cross slide 6, which are mounted on a double-armed lever 24 in the pot-like grinding wheel 18 via an axis 25 on a support arm 26 of the respective cross slide. 6 is articulated.
  • the guide rollers 23 can always rest on both sides of the grinding wheel 18 on the side edges of the ski.
  • a locking device 27 in the form of a locking cylinder the free pivoting movement of the lever 24 can be locked so that a side guide for the carriage. 6 also results when one of the two guide rollers 23 is already outside the side edge of the ski 1.
  • a supported on the guide 8 Anstellzylinder 28 engages the Anstellschlitten 9.
  • a control device which controls the actuators 11 as a function of the ski length related to the position of the grinding engagement so that different angles at the steel edges result in certain longitudinal sections, in addition between the outer and the inner edge of the ski. 1 can be distinguished.
  • control device can influence the respective requirements without significant additional expenditure on the feed speed of the ski relative to the grinding device, the speed of the grinding device and / or the grinding pressure as a function of the position of the grinding engagement relative to the ski length Device, the running and leadership of a ski 1, especially under racing conditions, be sensitively adapted to the snow and piste conditions and the driving style of the skier.
  • the setting device for the grinding angle could also include an actuating drive for the known stops for the guide 8 of the Anstellschlittens 9.
  • the feed direction 10, which results from the relative movement of the ski 1 receiving carriage 20 relative to the grinder 16 is given only for example, because the steel edge processing is of course possible in opposite directions, which is always utilized when the processing in several stages There is a return and a return.
