Definitions
- the invention relates to a device for dressing a grindstone for grinding a tread structure for a ski, consisting of a rotary drive for the grindstone, from one to the peripheral surface of the Grinding stone adjustable, having at least one cutting insert Dressing tool and from a feed drive for axially parallel relative movement of the dressing tool opposite the grindstone.
- a rotating whetstone is used to machine the tread of a ski used, the circumferential surface has opposite thread grooves, so can with the help of such a grindstone the tread of the ski with an appropriate Structure are ground, with the advantage that with Except for any waxing or edge polishing, post-processing the tread is unnecessary.
- the possible fineness of the tread structure limited only by the dressing tool for the grindstone, that of at least one protruding against the peripheral surface of the grindstone Cutting insert in the form of a stripping diamond.
- the dressing tool For dressing of the grindstone is the dressing tool parallel to the axis rotating grindstone to move, with the relative axial feed rate of the dressing tool in relation to the grindstone with the speed of the grindstone the slope of the through the Cutting insert in the circumferential surface of the grindstone cut thread groove certainly.
- the fineness can also be achieved via this pitch of the thread grooves the grindstone structuring and thus the delicacy of structuring one with specify a ski tread machined for such a grindstone.
- a ski can only do the fineness of its structure be specified, but not advantageous to the respective requirements adapted structure course, which is influenced by different influencing factors, such as type of snow, Snow temperature, type of tread, type of ski or ability of the ski user.
- the invention is therefore based on the object of a device for Dressing a grindstone to grind a tread structure for one Skis of the type described in such a way that grindstones for the Production of various structural shapes and subtleties to take account of the predefined influencing variables are trained quickly and reproducibly can be.
- the invention solves this problem in that for the feed drive and / or the rotary drive is a control device with an input device selectable control program memory and with one to the control program memory connected evaluation circuit for program-related Definition of position-dependent switching points for the speed of the Feed drive and / or the rotary drive is provided.
- the invention is based on the knowledge that between the two crossing, opposing thread grooves remaining, diamond-shaped in plan Ridges form rows that are transverse to the direction of rotation of the grindstone extend and one of the ratio of the slopes of the intersecting Include the thread groove dependent angle with the direction of rotation. at matching slopes of the intersecting thread grooves the rows of diamond-shaped bars perpendicular to the direction of rotation. at different gradients result depending on the gradient difference a corresponding inclination of these rows of diamonds, which one accordingly inclined course of the tread pattern compared to the Longitudinal axis.
- the pitch of the respective thread groove is determined
- Control device for the feed drive or the rotary drive a control program memory assigned in which various control programs for Predefined structural shapes of the skiing surface are stored, so that over the input device only that for a specific tread structure stored control program must be selected in order to be sent to the Program memory connected evaluation circuit of the control device the switching points for the speed of the feed drive or To be able to specify rotary actuator.
- These switchover points are determined by the program determined and determined the depending on the axial position Change the pitch of the thread groove by the puller in the Circumferential surface of the grindstone is cut.
- the change in the inclination of the structures can additionally be shifted from the axial longitudinal center of the grindstone to special asymmetrical conditions for the displacement of the water film between the tread and snow, such as this with cross-country skis can be advantageous if, according to an ice skating technique compared to an alpine ski, special, asymmetrical load conditions result.
- the Thread grooves also include a slope that changes continuously with the angle of rotation have, for example, a wavy structure in the tread to be able to grind.
- the evaluation circuit is sent to a program data memory for via the input device depending on the selected control program specifiable characteristic data for the control program connected, This allows the control system to be set in a simple manner using the specifiable characteristic data Be influenced to the control program to the desired To be able to adapt requirements. You can use these characteristics For example, the inclination relationships that are repeated over the length of the ski Sections of the tread structure, the fineness of the tread structure or a possible side shift of the selected structure can be set. These are program-related queried and entered via the input device Characteristic data are then stored in the program data memory of the evaluation circuit to determine the speed and the position-dependent Switchover points for the speed of the feed drive and / or the Rotary drive specified. Since it only depends on the slope of the Circumferential surface of the grindstone these gradients can either be via the feed drive or the rotary drive to be controlled. But of course it is also possible to get one Control via the feed as well as the rotary drive.
- Thread pitches Since the change in the at different pitches of the thread grooves Thread pitches must be determined axially, is a location assignment between dressing tool and grindstone required. This location assignment can be easily achieved by constructing the control device Position switches arranged according to the axial length of the grindstone for the feed drive is connected. These position switches are the Control device transmits predefined actual positions for the feed drive, between which the feed control with sufficient accuracy without an additional position control can be carried out. An additional Position control is of course also possible.
- the grindstone to be dressed is 1 stationary, while the dressing tool 2 on a parallel to Rotary axis of the grindstone 1 slidable carriage 3 is provided.
- the Carriage 3 is guided via a threaded spindle 4 along a carriage guide 5 moved by a feed drive 6, which is designed as an electric motor.
- the Grinding stone 1 is driven by a rotary drive 7, which is like the feed drive 6 is controlled with the aid of a control device 8.
- the control the feed drive 6 and the rotary drive 7 can be different Control programs are carried out, which are stored in a control program memory 9 are and can be selected via an input device 10.
- the Boundary conditions of the individual control programs are determined by characteristic data fixed, which can be specified via the input device 10 in order the selected control program according to the respective requirements to be able to adapt.
- the specifiable characteristic data are via the input device 10 read into a program data memory 11, this Provides characteristic data of an evaluation circuit 12, which the reference variables for controlling the feed drive 6 or the rotary drive 7 determined and the control device 8 acted upon by these reference variables.
- the evaluation circuit 12 thus determines the respective program Speeds for the feed drive 6 or the rotary drive 7 and the position-dependent switching points for any given speed changes established.
- the grindstone 1 can accordingly Specifications are processed using the dressing tool 2.
- the starting position is via a position switch 13 for the tool slide 3 detected for the employment of the dressing tool 2, its cutting insert, preferably a stripping diamond or a ceramic material, in the peripheral surface of the grindstone 1 cuts a thread groove.
- the slope this thread groove depends on the feed speed of the dressing tool 2 and the speed of the rotary drive 7 for the grindstone 1.
- This Speeds are used to achieve a certain pitch of the thread groove via the control device 8 depending on the selected control program and the selected boundary conditions. Are due to the program Changes in the pitch of the thread groove are provided for example, the feed speed of the carriage 3 when the the control device 8 predetermined changeover point changed.
- the axial Position of the carriage 3 is a rotary encoder 14 of the feed drive 6 recorded.
- the count of one connected to the rotary encoder 14 Counter, the position switch 13 to a predetermined count is set indicates the axial position of the carriage 3, so that this position detection the position-dependent switching points for the speed of the Feed drive 6 can be easily controlled.
- the feed drive 6 is displayed after the program-related speed changes at the end of the Feed line switched off, which is monitored by the position switch 15, the counter for the turning steps to compensate for any errors sets a predetermined value.
- the changeover points for changing the feed rate are again caused by the control device 8 for a program-related Dressing of the grindstone 1 ensures that with the help of this grindstone 1 To be able to grind ski surface with a selected structure.
- the invention is of course not based on the illustrated embodiment limited.
- the grindstone 1 with its rotary drive 7 on a sled compared to the unmovable Dressing tool 2 can be moved, since it is only on an axial relative movement the dressing tool 2 arrives opposite the grindstone 1 in order to to be able to cut a thread groove in the rotating grindstone 1.
- the dressing tool could have a controlled actuator drive be equipped so that over the depth of the thread grooves additional design options for the tread structures to be ground is achieved.
- the position switches 13, 15 could also be the evaluation circuit 12 are assigned, as this is dashed in the drawing is indicated. In this case, the respective end points for the position control of the slide 3 of the control device 8 via the evaluation circuit 8 specified.
- grindstones 1 for different types of ski can be dressed in the same way, but naturally in terms of The tread structure to be selected is considered according to the type of ski must be because z.
