Definitions
- the invention relates to a device for reworking a steel edge of a ski with at least one grinding device consisting of a cup-shaped grinding wheel driven by a motor with an axis of rotation extending transversely to the direction of advance, with a bearing block arranged on an adjustment slide, one bearing block transverse to the direction of advance and perpendicular to the axis of rotation of the grinding wheel forms a pendulum axis for the grinding device, with a guide for the positioning slide, which is rotatably mounted about an axis running in the feed direction in a cross slide that can be moved transversely to the feed direction, and with an adjusting device for the angular position of the guide of the positioning slide.
- the optional processing of the side or bottom edge is done by a Pivoting adjustment of the grinding device around an axis running in the feed direction enables a pivot stop to determine the respective angular position of the grinding device and thus the angle of the steel edge in the side or bottom edge area.
- the desired grinding angle in the side and bottom edge area can be set by adjusting these swivel stops.
- the adjusting carriages accommodating the grinding devices are mounted on cross slides which can be moved independently of one another.
- the guides for the positioning slides of the grinding devices in the cross slides can in turn be pivoted about an axis running in the feed direction between the stop-limited basic positions for the optional processing of the bottom and side edges, with the help of swing cylinders.
- the pot-like grinding wheel is placed on the face of the steel edge area to be ground at a predetermined angle, which determines the later edge angle of the machined steel edge and is exactly maintained over the ski length. Despite this exact adherence to the edge angle over the length of the ski, the driving and guidance less satisfactory with increasing waistline of the skis behavior of the steel edges, especially at higher loads, such as occur in ski racing.
- the invention is therefore based on the object of designing 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 repeatedly that advantageous driving and guiding properties for the ski result for the respective requirements.
- the adjusting device for the angular position of the guide of the positioning slide has an actuating drive which can be controlled with the aid of a control device depending on the position of the loop engagement related to the ski length.
- the actuator comprises a regulated electric stepper motor with a low-backlash gear, which is connected to the guide for the positioning slide.
- the alignment of the grinding device corresponding to the course of the edge via the pendulum axis running perpendicular to the axis of rotation of the grinding wheel and transversely to the feed direction means that the pot-like grinding wheel has to be supported on the end face in the region of two circumferential sections on the steel edge of the ski which runs like a tendon relative to the grinding wheel, which is in the end regions of the Skis can lead to difficulties if the steel edge is to be machined to the end area while maintaining precise grinding angles.
- the grinding device can be rotatably connected to the bearing block via a locking device, so that the grinding wheel can also be used with one-sided support on the steel edge to be ground for machining the ski ends.
- a double-armed lever with two guide rollers provided on both sides of the grinding device for the lateral longitudinal edges of the ski can be mounted on the cross slide, so that the possible pendulum movement of the double-armed lever results in the guide rollers resting independently on the lateral longitudinal edges of the ski.
- This support of the cross slide with respect to the ski, which is held for processing, is only effective if both guide rollers are in contact with the ski. So that support can also be made possible via only one guide roller, which is necessary in the end regions of the ski, the lever can be connected to the cross slide in a rotationally fixed manner by a locking device with the guide rollers in its respective pivot position.
- the control device for changing the edge angle to be ground over the length of the ski opens up the simple possibility of also controlling other grinding parameters as a function of the position of the looping intervention, which is related to the length of the ski.
- the grinding pressure can be acted upon by a corresponding actuation of the positioning cylinder for the positioning carriage, and the speed of the grinding wheel and / or the feed speed can be changed in order to have a corresponding influence on the surface quality of the grinding surfaces, which in cooperation with a corresponding one Design of the edge angle has an advantageous effect on the ski guidance and the hold of the ski on a hard or icy surface.
- the respective control parameters for grinding the ski edge of the control device must be specified in order to determine the reference variables.
- the control device can advantageously have an interface for entering these control parameters.
- a writing device for a preferably machine-readable identification of the respective control parameters can be controlled via the control device, so that the carrier of this identification can be attached to the ski, preferably glued on.
- the respective control parameters for repeated reworking of the ski edges can be automatically read into the control device so that they can only be changed in certain areas to improve driving behavior.
- FIG. 1 shows a device according to the invention for reworking a steel edge of a ski in a simplified plan view
- Fig. 3 shows the device according to FIG. 1 in sections in a front view in the region of a cross slide and
- Fig. 4 shows the cross slide with the grinding device of FIG. 3 in a bottom view.
- the device shown for machining the steel edges of a ski 1 has a frame 3 which is vertically displaceable on vertical guides 2 in a housing (not shown in any more detail) and which can be adjusted along the guides 2 by means of lifting cylinders.
- guide rods 5 are provided for two cross slides 6, which can be moved along the guide rods 5 with the aid of actuating cylinders 7 acting on the one hand on the side walls 4 and on the other hand on the cross slides 6.
- Guides 8 for positioning slides 9 are rotatably mounted on the cross slide 6, specifically about an axis of rotation a extending in the direction of advance 10 of the ski 1, as is indicated by dash-dotted lines in FIGS. 1 and 2.
- an actuator 11 which according to the exemplary embodiment consists of an electric stepper motor 12 and a low-backlash gear 13, preferably a bevel gear, on the output shaft of which the guide 8 is seated in a rotationally fixed manner.
- the guide carriage 9 guided on guide rods 14 of the guide 8 carries a bearing block 15 for a grinding device 16, which comprises a motor 17 and a cup-like grinding wheel 18 and is held rotatably in the bearing block 15 about a pendulum axis b which runs perpendicular to the axis of rotation of the cup-like grinding wheel 18 and is aligned transversely to the feed direction 10.
- the grinding device 16 can be connected to the bearing block 15 in a rotationally fixed manner, which is what is achieved in the embodiment by a locking cylinder between the bearing block 15 and the grinding device 16.
- the ski 1 is clamped for machining on a longitudinal slide 20, indicated only by dash-dotted lines in FIGS. 1 and 3, for machining on rubber-elastic supports 21, so that when the frame 3 is lowered, hold-down rollers 22 mounted in the frame 3 via the guides 2 rest on the running surface of the ski 1 and determine a reference plane for machining the steel edges, as can be seen in FIG. 2.
- guide rollers 23 are provided in the cross slides 6, which are mounted on a double-armed lever 24, which in the area of the cup-shaped grinding wheel 18 has 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.
- the free pivoting movement of the lever 24 can be blocked by a locking device 27 in the form of a locking cylinder, so that there is a lateral guide for the slide 6 - o - also results when one of the two guide rollers 23 is already outside the side edge of the ski 1.
- a positioning cylinder 28 supported on the guide 8 engages the positioning slide 9.
- the actuating drive 11 of the adjusting device for the angular position of the guide 8 of the positioning slide 9 creates the conditions for changing this angular position and thus the edge angle of the steel edge during the grinding process.
- a control device is to be provided which controls the actuators 11 in dependence on the position of the loop engagement in relation to the length of the ski in such a way that different angles result at the steel edges 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 feed speed of the ski relative to the grinding device, the rotational speed of the grinding device and / or the grinding pressure as a function of the position of the grinding engagement in relation to the ski length, depending on the respective requirements, without any significant additional effort, can be influenced with the aid of the invention Device the running and guiding properties of a ski 1, especially under racing conditions, can be sensitively adapted to the snow and slope conditions and to the skiing style of the skier.
- the adjusting device for the grinding angle could also include an actuator for the known stops for the guide 8 of the adjusting slide 9.
- the feed direction 10, which results from the relative movement of the carriage 20 receiving the ski 1 with respect to the grinding device 16, is only given, for example, because the steel edge machining is of course also possible with the feed direction in the opposite direction, which is always used when the machining is carried out in several stages There is a return and a return.
