Definitions

  • the invention relates to a grinding or polishing disc consisting of a platter with attachable grinding or polishing cloth, which can be clamped in a drive chuck, in particular a hand drill or do-it-yourself machine, by means of a shaft piece.
  • Grinding or polishing plates are known to which the grinding or polishing fabric is interchangeably applied by means of a pressure sensitive adhesive or Velcro fastener.
  • These known grinding or polishing plates have a rigid shaft piece for clamping in chucks of hand drills or home improvement machines. This can be used to grind and polish edges, but this version is only poorly suited for flat sanding and polishing, since even slight tilting can easily cause recesses or creases in the surface, which even an elastic platter cannot compensate for.
  • the grinding and polishing disc according to the preamble of claim 1 according to the invention is characterized in that the tube is axially displaceable with respect to the flexible shaft and can preferably be screwed by means of a threaded part at the entry of the flexible shaft at the turntable, as a result of which both flexible and rigid Setting for the grinding and polishing wheel is made possible.
  • a pipe or bolt can serve as a slide-in or slide-in or a screw-over nut serves as slide-over, which can be screwed onto threaded parts on the flexible shaft.
  • the threaded pieces are expediently arranged on the flexible shaft with an intermediate distance to the limit of their lateral flexibility.
  • one threaded piece can hold the turntable by means of a flange and a union nut, and the second threaded piece serves to accommodate the union nut which can be screwed together with two threaded pieces for stiffening.
  • the grinding or polishing disc consists of a platter 1 with applied grinding or polishing fabric 2. This can be applied in a conventional manner by means of adhesive or Velcro fastener.
  • the shaft piece for clamping in the drive chuck of a hand drilling or DIY machine M consists of a flexible shaft 3 which, according to FIG. 2, can be pushed over a rigid tube 4 and screwed onto the threaded piece 5 at the entry of the flexible shaft 3 at the platter 1.
  • This grinding and polishing wheel with a flexible and rigid drive shaft can be used for flat and edge grinding, without having to change over with another tool.
  • the grinding and polishing disc consists of a platter 6 and applied grinding or polishing fabric 7, in which the shaft piece for clamping in the drive chuck of a hand drill or home improvement machine M consists of a flexible shaft piece 8 and a rigid shaft piece 9 , wherein the rigid pipe 10 to be pushed over can be moved, fixed or screwed between the two shaft connectors 8 and 9.
  • a rigid bolt that can be inserted into the flexible hollow shaft can also be used accordingly. This can also be screwed on the one hand or can only be firmly inserted in a corresponding sleeve piece and have a flange or over-sleeve on the projecting part of the flexible shaft opposite the hollow shaft for clamping in the drive chuck.
  • FIG. 4 Another particularly preferred exemplary embodiment is shown in FIG. 4.
  • a rigid turntable 11 made of hard plastic, but in particular made of steel, with an applied grinding or polishing cloth 12 is used here appropriately inserted turntable 11 carries, while on the other hand on the flexible shaft 13 a second threaded piece 17 is applied at a distance 18, for receiving the union nut 19.
  • the union nut 19 is screwed up, as shown, for the flexible shaft, as shown in dash-dotted lines, a limited flexibility by the threaded pieces 14, 17 as stops, while when the union nut 19 is screwed down and extends both over the threaded piece 17 and over 14, a corresponding stiffening is achieved.
  • surface grinding can be done here with a flexible shaft and edge grinding with a stiffened, ie rigid shaft, without the need for a tool change.
  • the rigid shaft end 20 is used for clamping in the drive chuck of a hand-held or DIY machine M.

Claims (6)

1. Meule ou roue polisseuse qui consiste en une assiette (6, 11) où un tissu de meulage ou de polissage (7, 12) peut être monté et qui, à l'aide d'un arbre, peut être fixé dans un mandrin de commande, surtout dans une perceuse portative ou une autre machine de bricoleur. L'arbre est en partie flexible (8, 13) et doté d'un tube qui sert à limiter sa flexibilité latérale. Le dispositif est caractérisé par le fait que le tube (10) est axialement coulissable par rapport à l'arbre flexible (8, 13) et qu'il peut être vissé, de préférence avec une douille filetée, au point où l'arbre flexible entre dans la'assiette (7, 12).
2. Meule ou roue polisseuse d'après le droit 1, caractérisé par le fait qu'un écrou-chapeau (19) sert de couverture. Il peut être vissé à l'aide de douilles filetées (17, 19) placées sur l'arbre flexible (13).
3. Meule ou roue polisseuse d'après les droits 1 et 2, caractérisé par le fait que les douilles filetées (14, 17), placées sur l'arbre flexible (13), et la distance entre les deux (18) servent à limiter sa flexibilité latérale.
4. Meule ou roue polisseuse d'après le droit 3, caractérisé par le fait que l'une des douilles filetées (14) tient l'assiette (11) à l'aide d'un collet (15) et d'un écrou-chapeau (16) et que la deuxième douille filetée (17) sert à porter l'écrou-chapeau (19) qui peut être vissé aux deux douilles filetées (14, 17) afin de rendre le tout inflexible.
5. Meule ou roue polisseuse d'après un des droits 1 à 4, caractérisé par le fait que la partie flexible de l'arbre (8) est combinée avec au moins une partie inflexible (9). Le tube inflexible (10) ou le boulon inflexible est alternativement coulissable entre les deux parties de l'arbre (9, 8) où il peut être fixé.
6. Meule ou roue polisseuse d'après un des droits précédents, caractérisé par le fait que l'assiette (11) où un tissu de meulage ou de polissage (12) peut être monté, est une assiette inflexible, fait de matière plastique ou d'acier.
