Definitions

  • the invention relates to an adjustable sanding pad for machining a profiled workpiece, with a package defining a profiled grinding surface from side by side, arranged side by side, upright to the grinding surface arranged slats, which are mounted in a housing against each other transversely to the grinding direction and with the help of a Clamping device can be clamped in the respective displacement position.
  • an abrasive in particular sandpaper
  • a profiled workpiece In manual grinding, an abrasive, in particular sandpaper, is guided by hand over a profiled workpiece.
  • profiled sanding blocks made of wood or cork are used to hold the abrasive between themselves and the workpiece.
  • the abrasive is either held by hand on the sanding block, glued to the sanding block or fastened to it with clips.
  • the production of the sanding blocks is very time-consuming and costly since a separate sanding block has to be made for each possible profile shape.
  • the invention has for its object to provide a sanding pad whose contour on the one hand quickly adjust to the profile shape to be machined and on the other hand can be fixed exactly in the desired profile shape, the sanding pad being suitable for manual as well as for mechanical grinding should.
  • a quick and safe way of fastening the abrasive to the abrasive pad is to be created.
  • the lamellae of the package can be inserted from a stop-limited starting position against spring force into the housing and that the clamping device acts on the end of the lamellae in the grinding direction with a clamping force.
  • the profile shape of the grinding pad can not only be adapted quickly and precisely to the profile shape of the workpiece to be manufactured, but the grinding pad can also be fixed exactly in the desired profile shape.
  • the disk set is supported on the side opposite the grinding surface on an elastic housing insert and / or the clamping device consists of an adjustable clamping plate in the grinding direction, which is mounted in an end face of the housing and with the opposite end of the housing cooperates as a counter bearing.
  • the position of the individual slats relative to one another is fixed in the desired position with the clamping plate acting on the end face of the plate pack.
  • the housing preferably has Velcro fasteners for fastening a covering of the grinding surface.
  • abrasive An abrasive made of paper, linen or the like placed between the workpiece and the sanding pad nestles against the sanding pad and the workpiece, after which it is moved over the workpiece by hand or by machine.
  • FIG. 1 an abrasive pad according to the invention in a partially sectioned front view
  • FIG. 2 the abrasive pad in a section along the line II-II from FIG. 1.
  • Fig. 1 shows a pressed on a profiled workpiece 10 grinding pad 3 with adapted to the profile shape of the workpiece 10 slats 6.
  • the in a housing 2, from the individual, in the unclamped state mutually displaceable slats 6, existing package is in the desired position with a clamping screw 8 guided in a nut 7.
  • the nut 7 acts on a clamping plate 14 which is adjustable in the grinding direction and which is mounted in one end face of the housing 2, cooperates with the opposite end face of the housing 2 as a counter bearing and clamps the lamellae 6 between the contact surfaces 12 and 13 (FIG. 2).
  • An abrasive 9 is fastened to the housing 2 on both sides by means of Velcro fasteners 5.
  • the slats 6 have an elongated hole 11, the upper end of which is pressed by an elastic material 1 against a stop pin 4 when the slats 6 are not clamped.
  • the grinding pad 3 is set when the clamping screw 8 is loosened, the lamellae 6 guided between the contact surfaces 12 and 13 first being pressed against the stop bolt 4 by the elastic housing insert 1 enclosed in the housing 2, and the lamellae 6 thus extended in one plane. be judged. Because the grinding pad 3, initially without the abrasive 9, is placed on the workpiece 10 and pressed against the resistance of the elastic housing insert 1 until it has accepted the workpiece profile. Now the clamping screw 8 is tightened and thus the exact profile shape is fixed. Subsequently, the grinding body 9 is placed over the now profiled disk pack, placed on the workpiece 10 again and the abrasive 9 is fastened to the housing 2 by means of the Velcro fasteners 5.
  • the workpiece 10 can be ground manually or by machine.

Abstract

L'invention concerne un coussin de meulage réglable (3) pour l'usinage d'une pièce profilée (10), comprenant un paquet de lamelles (6) alignées les unes à côtés des autres perpendiculairement à la direction de meulage, et placées de chant par rapport à la surface de meulage, montées à l'intérieur d'un boîtier (2), mutuellement déplaçables perpendiculairement à la direction de meulage, et pouvant être fixées en leurs positions de déplacement respectives, au moyen d'un dispositif de fixation. En vue d'obtenir un coussin de meulage (3) ayant un profil qui, d'une part, peut être réglé rapidement sur la forme du profil à usiner et, d'autre part, fixé exactement dans la forme voulue du profil, l'invention est caractérisée en ce que les lamelles (6) du paquet sont introduites dans le boîtier (2), à l'encontre d'une force élastique, en une position initiale de limite de butée, et en ce que le dispositif de fixation sollicite, par une force de serrage, les lamelles (6) sur le côté avant, dans le sens du meulage.
