Definitions

  • the invention relates to a drill stand, in particular for Rock drill, with a pedestal that is attached to a base plate and a carriage with a receptacle for a drilling machine with a Drilling axis carries, with the pedestal a column axis and, each in axially parallel arrangement, two opposing guide grooves with a trapezoidal cross-section and a linear row of teeth and the slide with a pinion engaging in the row of teeth with a Drive shaft and with guide bodies for engaging in the guide grooves Is provided.
  • drilling machine Insofar as the term "drilling machine” is used below, it is included not just to understand a hand drill, but every drilling unit with a drive motor, a reduction gear and one Fastening device for a drill, even if this drilling unit is permanently connected to the slide.
  • the drilling axis lies on the Center of gravity of the footplate opposite side of the pillar, so that it can be drilled into the footprint of the stand, and even in room corners.
  • the footprint consists of natural and Artificial stone, made of concrete u.
  • Diamond bits are preferably used as drills, So-called "core drill” in question.
  • the term "pedestal” not only means that its axis is in operation must be vertical; the pillar can rather be compared to the Reference plane of the footplate can be pivoted, and the footplate can both on floors and on walls and undersides of ceilings, i.e. in Overhead position.
  • the base plate is usually used by means of a vacuum device or a dowel connection in the largest possible Close to the hole to be made connected to the surface to be drilled. The footprint is therefore more appropriate than "work surface" designated.
  • a drill stand with a pedestal which has a cylindrical surface that only has a protruding surface Rack is interrupted and on a sled with a cylindrical inner surface is also displaceable. Diametrically opposite Guide grooves and free of play in these from the carriage Guide bodies are not provided.
  • a drill stand whose column has a square cross-section from which a toothed rack projects and on the one a C-shaped slide with a partially complementary one Inner cross section is displaceable. Diametrically opposite guide grooves and play-free into these guide bodies which can be pressed in from the slide are not provided. On one leg of the C-shaped slide guide there is a slide-free adjustable slide rail available. Through the diagonal The arrangement of the column cross-section on the base plate is the bending stiffness the pedestal only increased in two diagonal directions.
  • the pedestal has an approximately X-shaped cross-section on which a rack is attached and on which a complex C-shaped slide can be moved with two parallel guides.
  • Each of these tours exists from two double wedge-shaped sliders, one wedge surface each has a leadership role.
  • the double wedge-shaped sliders do not work against each other, but in the same direction, and only through the interaction of four sliders and four guide rollers parallel guidance is possible. The effort is only made because to combine the drill stand with other tool guides can.
  • Diametrically opposite guide grooves and free of play in them Slides that can be pressed in from the slide are not provided. Also are the guide rollers can only be adjusted in the axial direction around the slide to be able to lose weight, but not across it to ensure a play-free setting to be able to make.
  • the invention is therefore based on the object of a drill stand to specify the genus described above, in which the Section modulus at a given material cross section in is increased in all directions, games in the sled guide as far as be eliminated as far as possible, and in which the handling in strenuous Spatial positions is facilitated.
  • a base plate 1 with a virtual reference plane E-E, brought into a horizontal position using four leveling spindles 2 can be, for example, parallel to a work surface 3.
  • a Chamber 4 can be housed a vacuum suction device.
  • the base plate 1 by means of an elongated hole, a dowel and a Clamping screw to be attached to or on the work surface 3.
  • a knob 10 serves to pivot a centering lever, not shown.
  • a lockable stand column 8 arranged at its lower end provided with flats 8a between the bearing blocks 6, opposite the Base plate 1 can be determined by a tension lever 25 and at its upper End has a handle 9.
  • a carriage 11 with a receptacle 12 for an electric drill, which specifies a drilling axis AB-AB is up and down on the pedestal 8 movable.
  • the pedestal 8 has a linear row of teeth 13, and the carriage has a shaft 14 with a pinion 22 (FIG 5) by a hand lever that can be moved from one side to the other 15 is drivable.
  • the shaft 14 can be locked by a locking bolt 23 and runs against an adjustable stop as it moves down 24th
  • the standing column 8 has two on diametrically opposite sides trapezoidal guide grooves 16, on the bottom of which a scale 17 is arranged.
  • the leadership happens via complementary trapezoidal prismatic slide rails 18 ( Figures 4, 6, 7 and 8) using four Tensioning screws 19 free of play but slidable against the pillar 8 are braced.
  • a further handle 20 under which for the vacuum operation is a vent valve 21, the device can transport and hold when attaching.
  • the outline of the column 8 is by a cylindrical surface defined, which is indicated by a circle "K".
  • the stand column 8 is a Extruded part and consists of a light metal alloy.
  • Circle “K” Within this Circle “K” are the linear row of teeth 13, the two guide grooves 16th and two pairs of grooves 26 and 27. Their teeth 13 facing Groove flanks 26a form a dovetail guide 28 for the Stop 24, which will be described in more detail below.
  • Dovetail guide 29 for a not shown, clampable oblique strut, the stiffening of the pillar 8 with respect to the river plate 1 serves.
  • Figure 3 also shows that 11 spirit levels 30 and 31 are arranged in the carriage are for leveling the footplate 1 when standing vertically or horizontal pillar 8.
  • Figures 3 and 4 show that the carriage 11 has an approximately horseshoe shape trained base body 32, in the legs 32a which is trapezoidal prismatic slide rails 18 sit by the clamping screws 19 can be pressed into the guide grooves 16. From the base body 32 is the receptacle 12 for the holder of a drill, not shown in the form of a boom.
  • the legs 32a have axially parallel grooves 33, through the bottom of the groove, the clamping screws 19 are passed. That with the drive shaft 14 integrally formed pinion 22 has in its center radial bores 34 for the engagement of the locking bolt 23, of which only one hole is shown.
  • the locking bolt 23 lies on that of the drilling axis AB facing side of the pillar 8.
  • the drive shaft 14 has Hexagonal profiles 35 deviating from the cylindrical shape at both ends for attaching the hand lever 15. These profiles 35 are by a Circumferential groove 36 interrupted, in which one arranged on the hand lever 15 Interlocking body 37 ( Figure 9) engages.
  • Figures 6, 7 and 8 show one of a plastic (e.g. polyamide) existing slide rails 18, namely Figure 6, the external view with two Stepped bores 38 for the engagement of two clamping screws 19 below Interposition of a metal socket (Figure 4, top left).
  • Figure 7 shows a side view
  • Figure 8 is a rear view.
  • the guide rail is injection molded and has two end regions 18a, the cross sections of which are shown in FIG and a middle piece 18b, the cross section of which is weakened and is T-shaped. As a result, the end regions 18a become mechanical decoupled so that they are always full and defined or without play in the Guide grooves 16 can rest.
  • the hand lever 15 has a hub 39, with a radial bore 40 in which the locking body 37 (a ball) is mounted radially movable.
  • the hub 39 is from a sliding sleeve 41 surrounded, which is displaceable against the force of a compression spring 42 and one between two holes with different diameters Has control edge through which the locking body 37 in and out Engagement with the circumferential grooves 36 in the drive shaft 14 can be brought.
  • the stop 24 for the slide 11 is in one piece (made of plastic), but weakened by a central groove 45. Due to the complementary shape, the stop 24 is on the dovetail guide 28 of the stand column 8 can be pushed on in the axial direction and can be fixed by means of a clamping screw 46. The one beyond the central groove 45 lying sections 24a and 24b are when tightening the clamping screw 46 against each other - as in the prior art - undesirable rotatable.
