Definitions

  • the invention relates to a drill stand for hand drills, consisting of table tops with a guide column, a height-adjustable and clampable bracket on this, a slide that is guided on the column, a column-parallel rack element that is attached to the slide standing up, one rotatable in the boom mounted shaft, which carries a drive pinion which is in drive engagement with the rack element and with a clamping neck supported by the slide for the collar of a drill.
  • the object of the invention is to produce a drill stand of the type mentioned more efficiently.
  • the advantage of the invention is that the essential parts of the drill stand, namely Aus_ boom, slide and holder have the same profile cross section. This training is of crucial importance for the rational production of the drill stand, since all three elements can be produced from the same extruded profile by simply cutting them off. Another section of this extruded profile forms a column base attached to the underside of the table.
  • the table top itself, the column and the rack element and even the drive pinion are sections of our own extruded profiles, especially aluminum profiles, which can be manufactured very precisely, so that subsequent finishing is not necessary.
  • the boom and slider can be swiveled around the column and the holder can be swiveled relative to the slider, making it possible to set the drilling axis in any given range.
  • the first channels are dimensioned so that there is a sliding guide with respect to the column and the drill collar. Thanks to the clamping device, the channel cross-section can be reduced to such an extent that the boom is clamped to the column and the drill collar is clamped to the holder.
  • the second channels are preferably corresponding with a smaller cross section formed so that the tubular rack element is displaceable in the boom, but the holder and the slide can be clamped on the rack element.
  • the drill stand shown in the drawing consists of a table top 10, a circular cylindrical column 12, a bracket 14 clamped to the column, a slider 16 guided on the column, a holder 18 fastened to the slider 16 for a drilling machine 20, a rack element 22 in Form of a profile tube with a groove 35 and in this rack 24 J inserted in the bracket 14 rotatably mounted actuating shaft 26 on which a drive.
  • Pinion 28 is fixed, which engages in the rack 24, an operating lever 30 which is fixed from the protruding end of the shaft 26, two tension springs 32 which are suspended on cross bars 31, 33 of the boom 14 and the slide 16 and a column base 34th , which is attached to the underside of the table top 10.
  • Boom 14, slide 15, holder 18 and column base 34 have exactly the same profile cross section and are cut off pieces of the same extruded profile which is designated by 80 in FIG. 10.
  • the outside diameter of the circular cylindrical column 12 which also consists of an extruded tube, corresponds to the inside diameter of an essentially circular cylindrical channel 36 of the profile section 80 (FIG. 10) with a sliding fit.
  • the outer diameter of the column 12 is equal to the standardized diameter of the collar of a conventional hand drill 20.
  • the profile section 80 has two side walls 38, 40 which extend parallel to one another in the central region and which are connected in one piece at the ends to circular cylinder walls 42, 44.
  • the diameter of a first circular cylinder wall 42 is approximately equal to the distance between the two side walls 38, 40.
  • the second circular cylinder wall 44 is smaller in diameter and is connected to the side walls by inclined wall sections. It delimits a second circular-cylindrical channel 45.
  • Both circular cylinder walls 42, 44 point in the middle plane of symmetry 50 in the wall facing away from each other cut open slots 51, 53, adjacent to which adjoin the circular cylinder walls 42, 44 each outwardly pointing clamping webs 48, 48 and 66, 66.
  • Each pair of clamping webs has at least one pair of aligned holes, one of which is threaded.
  • a clamping screw 49 or 67 is arranged in each pair of holes.
  • the heights of the profile sections for boom 14, slider 16 and holder 18 can be the same. However, it is sufficient to design the slide with a lower height than the holder and this narrower than the boom.
  • the second circular cylinder wall 44 which is smaller in diameter, has in the plane of symmetry 50 an inner slot 62 diametrically opposite the slot 53, the width of which is equal to at least the width of the drive pinion 28 because when the profile section 80 is used as a bracket 14, it extends through this inner slot.
  • the inner diameter of the second channel 45 accommodates the profiled tube 22 with sliding seat 7 .
  • the clamping screws 67 of the slider 16 and the holder 18 are tightened, as a result of which the slider and holder are clamped to one another and to the profile tube are.
  • the groove 35 is so deep that the rack 24 used does not protrude beyond the outer radius of the tube 22.
  • the pinion 28 engaging in the toothed rack secures the profile tube to a relative rotation in the boom 14.
  • the profile tube is guided so that it can move in the channel 45 of the boom.
  • the table top which is cut from an extruded profile section, is symmetrical to the central longitudinal central plane and has two lateral foot webs 52, furthermore fastening grooves 54 and two vertical ribs 56, 58, the clear distance of which is equal to the outer distance of the two side walls 38, 40 .
  • the profile section 80 which is inserted as a column base 34 between the ribs 56, 58 and, after alignment of its circular-cylindrical channel 36, is welded to a circular opening 60 in the table top.
  • a slotted profile tube piece 70 is clamped in an infinitely variable, longitudinally adjustable manner and, adjacent to the slot, has outer clamping webs 64 with aligned holes for a clamping screw 68. Opposite these clamping webs, the pipe section 70 has an outwardly pointing rib 72, in which a groove is formed, in which a ver with a scale see rod 74 is attached, which allows reading and adjusting the drilling depth.
  • the pipe section 70 also acts as a depth stop.
  • the rack 24 consists of a section of a ribbed extruded profile, which has at one end a hook 76 pointing away from the ribbed side, which forms a slightly widening clamping groove towards the free end of the hook leg 78, the base width of which is the same less an undersize sufficient for a clamp fit is the wall thickness of the tube 22 measured between the bottom of the groove 35 and the inner surface of the tube 22.
  • the toothed rack has a bore for a fastening screw 84 screwed into the tube 22.
