Definitions

  • the invention relates to a miter stop module for a machine tool according to the preamble of claim 1, and to a woodworking machine having such a miter stop module according to the preamble of claim 15.
  • a locking screw which can be actuated by star grip or handwheel, which penetrates a block fixedly mounted on the machine table and can be screwed against a contact surface of a pivoting section of the miter stop module running along a circle segment. If the locking screw is released, a swivel section of the miter stop module, which is received pivotably on the machine table, can be swiveled, whereby the operator can adjust the miter angle via an angle scale along the circle segment before moving the swivel section by means of the locking screw fixed.
  • the object of the present invention is therefore to provide a miter stop module or a woodworking machine with a miter stop module, which simplify the operation of the machine.
  • the miter stop module in this case has a quick positioning device, which allows rapid positioning of the workpiece stop or the pivoting section on the most frequently used miter angles (quick positioning angle), as well as a scale representing this number of Schnellpositionierwinkeln for the operator.
  • a quick positioning device which allows rapid positioning of the workpiece stop or the pivoting section on the most frequently used miter angles (quick positioning angle)
  • a scale representing this number of Schnellpositionierwinkeln for the operator.
  • all types of analog or digital scales which transmit haptic, acoustic or visual signals to the operator, which reproduce the respective quick positioning angle, are suitable as the scale.
  • Particularly suitable in the sense of a simple structure is an analogue reading scale on which all Schnellpositionierwinkel are plotted.
  • the number Schnellpositionierwinkel for example, all on a grid with 15 ° increments to the longitudinal direction angle in the swing range include, preferably also still the two angles +/- 22.5 ° to the transverse direction and includes a useful pivoting range, for example, +/- 60th ° around the transverse direction (perpendicular to the longitudinal direction) or transverse angle direction extends.
  • a simple and fast positioning of the workpiece succeeds.
  • the quick positioning can be designed so that not only provisionally position the pivot portion of the miter stop module, but also in the set to the desired Schnellpositionierwinkel Miter position for the subsequent operation (for example, cut on the circular saw) can be finally positioned.
  • the quick positioning is only provided for positioning on one of the Schnellpositionierwinkel and provisionally fixing the pivot portion in this position, wherein an additional fixing device is provided for the final fixation in this position.
  • This design has the advantage that the above-described, in existing Miter stop modules already existing fixer for final fixation of the pivot portion can be used and the quick positioning therefore only for quick positioning on the desired Schnellpositionierwinkel and provisional fixing in this position until or during the final fixing must be formed on the fixing device and therefore may have a simple and inexpensive structure, for example according to the below-described, advantageous developments of the invention.
  • the fixing device can, as for example in the case of the abovementioned common fixation devices, be designed so that the pivoting section can not only be fixed in a position corresponding to one of the quick positioning angles, but also at any angle in the pivoting area.
  • the most common miter angles can thus be adjusted in a simple and rapid manner via the quick positioning device, whereas rarely used miter angles can be further adjusted without this positioning aid in the usual way.
  • the scale for the operator is easily standing up Read table height, so that he can quickly position the swivel section on one of these Schnellpositionierwinkel without having to lean forward.
  • a further fine adjustment scale with a finer resolution can advantageously be provided in addition to the quick positioning scale, for example a dialoge angular reading scale already frequently used in connection with the conventional fixing unit described above on the pivoting section with a fixed angular pull ,
  • the rapid positioning device can have a locking element that is movably received longitudinally in the longitudinal direction and the pivoting section has a circular segment-shaped outer dimension in the region of the scale or in its pivoting region.
  • the pivoting section has a circular segment-shaped outer dimension in the region of the scale or in its pivoting region.
  • At the outer dimension or in the vicinity of stationary positioning receptacles for the locking element can be provided at the Schnellpositionierwinkeln so that the locking element can be brought into and out of engagement with one of the positioning recordings, when this positioning recording in the longitudinal direction with the locking element is aligned, so if Pivoting portion has been pivoted on the this positioning recording associated Schnellpositionierwinkel.
  • the operation and the structure of the miter stop module are further simplified if the positioning receptacles are formed as projecting from the top of the pivot portion positioning or as embedded in the top of the pivot portion positioning grooves. Because then these positioning pins or positioning grooves can be detected by the user at the same time as a scale for Schnellpositionierwinkel or at least as part of it.
  • the locking element can then be designed, for example, as a slide which can be moved in the longitudinal direction and which has a slide groove or a suitable slide pin which fits the positioning pins or positioning grooves.
  • the at least partially formed by the positioning or positioning grooves scale can also be read well by the operator at the same time.
  • the locking element has a locking portion with which it can be locked in engagement with one of the positioning recordings position, so that the Schnellpositionier worn not only for a provisional Fixation, but can be used to a final positioning of the miter fence on the desired Schnellpositionierwinkel.
  • Suitable for this purpose would be, for example, a hook on the free end of the slider, which can be inserted into a recess provided at the end of the positioning or the positioning groove, for example via a tilting mechanism, via which the slider can be tilted in addition to the movement in the longitudinal direction, wherein a biasing spring may be provided which biases the slider with its hook in the recess.
  • the locking element must then be guided safely across the longitudinal direction and even have a high material resistance to transverse movements.
  • a certain provisional Fixing the slide in the respective position recording can accomplish the slide groove or the slide pin of the slider two in the longitudinal direction acute angle converging contact surfaces and the positioning and two positioning the contact surfaces on the slider facing, parallel contact surfaces, wherein the distance of the parallel contact surfaces from each other corresponds to a mean distance of the acute angle converging contact surfaces.
  • a simple threading or threading of the slider on the selected positioning or in the selected positioning groove because the slide groove at its free end wider or the slide pin at its free end is narrower than the associated positioning pin or the associated positioning groove.
  • the locking element and the positioning seat wedged in a further insertion of the locking element in the associated positioning recording ie that the tapered contact surfaces run against the parallel contact surfaces and clamp there and thus a certain fixation of the quick positioning is achieved.
