Definitions

  • the present invention relates to the technical field of grinding machines, especially the hand grinders, and in particular a sanding pad for rotational drive on an output shaft of a Grinding machine.
  • Such a sanding pad is z.
  • a rotational drive of the Grinding plate on the output shaft of the (hand) grinder where this sanding pad automatically on the output shaft, in particular on a Driver, centered.
  • suction housing is provided with an exhaust pipe from which a suction hose extends to the respective suction device.
  • a laterally projecting handle is provided on the machine housing.
  • the handle is at the same time as Suction housing serving protective housing for drive elements of the Arranged sanding plate, hollow and formed with the cavity of the Protective housing connected.
  • the handle forms a discharge pipe for the Grinding dust, at the free end of the suction hose is attached, the extends away from the handle of the hand grinder.
  • the grinding wheel according to the publication DE 21 45 714 A1 has on her The entire surface of a perforation holes forming, with in the Inside the plate approximately radially extending channels in conjunction stand and their other end opens to the outside.
  • EP 0 781 629 A1 are directly or indirectly with a Machine or with a manually operable abrasive holder adaptable Abrasive and a work-fair application to a Machine grinding plate or on a grinding plate or on an actuatable Abrasive holder with or without suction suitable adapters known.
  • At least the abrasive article has a perforation that approximates evenly distributed over the entire surface of the abrasive body or at least is arranged partially and at least the the abrasive having penetrating layer, wherein the distance of the individual, the Perforation forming openings to each other and to the Extraction of the sanding plate or the grinding plate chosen so is that according to the document EP 0 781 629 A1, a nearly stagnant Transport of the grinding dust causes it to be.
  • a sanding pad for a sanding machine equipped with dust extraction DE 89 02 423 U1 in which the disk body for Grinding dust extraction with eight on an inner circle around the center distributed, transverse to the slice body plane openings and with eight on an outer circle around the center recesses formed in the free surface of the disk body, the about radially extending channels with the periphery of the Disk body and connected to the openings are equipped is, and attached to a disc of abrasive cloth abrasive material is congruent to the apertures on one of the circular lines Has holes, each arranged distributed on the inner circular line Openings at the bottom of a second recess opens, extending from the inner circular line to beyond a middle, third circular line extends. As a result, slices of abrasive cloth of any hole pattern be used.
  • the present invention is based on the object, a sanding pad of the aforementioned type so that the air flow or air flow with the grinding dust unbroken in the openings or openings of the support plate passes.
  • a Grinding machine such as hand grinder, to guide, where the Grinding resulting grinding dust by means of at least one in or on the grinder arranged sucking bell is sucked sees the invention in that the opening or opening in the support plate aerodynamically designed, so that the core of the present invention in one embodiment of the sanding plate, in particular the support plate, lies, when in the support plate for sucking off the sanding dust provided openings or openings aerodynamically shaped are.
  • the present Sanding plate is on the underside facing the sanding sheet Support plate at least one duct guide for the air with the Grinding dust provided.
  • the invention finally relates to a grinding machine, in particular a Hand grinder, comprising at least one sanding pad of the above set forth.
  • a sanding pad 100 is shown, the eccentric means a hand grinder designed in particular as an angle grinder 200 is drivable.
  • a hand grinder 200 a drive motor 204 with a preferably at right angles ablated output shaft 202, by means of which the sanding plate 100 is driven by way of rotational drive (see Fig. 1).
  • a protective housing for the Drive elements of the sanding pad 100 fastened this protective housing also serves as a suction housing for the costs incurred during grinding Abrasive dust 300.
  • a handle 208 attached by means of which the hand grinder 200 can be held during the grinding process see Fig. 1).
  • the actual grinding process causing abrasive sheet 80 is by means of a Velcro 70 held on a cushion or pad 60, on the side facing away from the hand grinder 200 surface 16 of the Support plate 10 is fixed (see Fig. 1).
  • the support plate 10 more (In the present embodiment: eight) air ducts 28 for the supply of the absorbed abrasive dust 300 to the openings 20, through which the sanding dust 300 is sucked off.
  • These channel guides 28 are for the air with the grinding dust 300 on the underside 16 of the support plate 10 substantially, because in this way the air flow or air flow continues unbroken and substantially unhindered in the openings 20.
  • the apertures 20 are formed approximately oval and extend from the center 12 of the support plate 10 radially to the peripheral edge 14 of the support plate 10 (see Fig. 3 to 6), wherein the openings 20 extend with its longitudinal center line 22 in approximately a circular arc (see , Fig. 5 and 6).
  • Another essential feature of the invention is an oblique Beveled the longitudinal side edges 24, 26 of each opening 20 given. While due to the direction of air flow or air flow of the grinding dust 300 from this air flow or air flow hardly detected first longitudinal side edge 24 of the opening 20 almost perpendicular runs, d. H. only very slightly ground or chamfered, is the severely affected by the air flow or air flow of the grinding dust 300 second longitudinal side edge 26 of the opening 20 ground very sharply or tapered to the air flow or air flow of the grinding dust 300th to offer as little resistance as possible, so that the air flow or air flow with the grinding dust 300 unbroken in the aerodynamically shaped Openings or openings 20 of the support plate 10 passes.
  • the openings 20 can be large or small. In in the event that only one aperture 20 (or eg an odd number At openings 20) is provided, the support plate 10 through Balance additional masses. Essential to the invention is in in each case the above-described aerodynamic design of the openings 20th
  • stiffening webs 50 On the hand grinder 200 facing top 18 of Support plate 10 are provided radially extending stiffening webs 50, by means of which the pressure loads of the support plate 10 is collected become. These eight stiffening webs 50 each extend approximately in half in the area between each two openings or openings 20 inside.
  • FIG. 3 and 4 of the hand grinder 200 facing Top 18 of the support plate 10 is shown, the Fig. 5 and FIG. 6 shows the underside 16 facing away from the hand grinder 200 the support plate 10.
