Definitions

  • the invention relates to a grinding device for grinding the surface of an approximately cylindrical or shaped workpiece, with a holding element and a grinding tool which can be fastened to it, preferably provided as sandpaper.
  • the object of the present invention is to provide a grinding device of the type described at the outset, with which pipes or the like can be ground, cleaned, polished or roughened in a very simple and rational manner.
  • the object is achieved in that at least one approximately semicircular cylindrical opening or an opening corresponding in cross section to the shape of the workpiece is formed on the holding element, on the inside of which fastening means are provided for holding the grinding tool.
  • the abovementioned fastening means are preferably provided as hook-and-loop fastener strips attached to the inside of the semicircular hollow body, by means of which sanding paper likewise provided with a hook-and-loop fastener can be removably fastened.
  • the grinding device according to the invention is particularly suitable for a hand-held grinding machine with a vibrating tool grinding plate, for which purpose the holding element has fastening means for detachable attachment to the grinding plate of the grinding machine.
  • FIG. 1 and 2 show a grinding device 10 which essentially has a plate-shaped holding element 12 and a semicircular hollow body 14 fastened thereon.
  • the holding element 12 is releasably attached to a hand grinder 20, the reciprocating linear or orbital vibration movement generated by the latter taking place in the longitudinal direction and / or on the circumference of the workpiece to be machined, which is designed as a tube 25.
  • This hand grinder 20 is known per se and is therefore no longer explained in detail below.
  • an approximately semicircular cylindrical opening 18 is formed in the shell-shaped hollow body 14, in which fastening means are provided for holding a grinding tool.
  • an adhesive Velcro tape 16 is attached as a fastening means, which extends over its semicircular inner circumference.
  • the grinding tool used as sanding paper 15 can be pressed into the hollow body 14 in the simplest manner and is then held therein. For this purpose, it is provided with an appropriate Velcro fastener on the back.
  • the holding element 12 has on its upper surface a fastening means, which is also designed as a Velcro tape 12 '. This enables the holding element 12 to be fastened to the grinding plate 23 of the hand-held grinding machine 20.
  • the correspondingly dimensioned holding element 12 and the hook-and-loop fastener tape are assigned to this grinding plate 23 12 'serves as a releasable fastening member. It can be very easily removed from the grinding plate 23 or reattached to it.
  • the mentioned opening 18 extends parallel to the reciprocating linear or orbital vibration movement of the grinding plate 23 of the grinding machine.
  • the hollow body 14 can be pressed onto the pipe 25 with the sanding paper attached, and due to the vibrating action of the sanding plate 23, this, for example a metal pipe, is extremely uniformly sanded on its surface within a very short time or polished to a high gloss using an appropriate sanding paper (polishing cloth) . With an appropriate fleece there is also the possibility of roughening the workpiece surface.
  • the hollow body 14 attached to the holding element 12 with the largest possible diameter, and for machining smaller workpiece diameters into the hollow body with correspondingly shaped, but smaller dimensioned tubular, semicircular inserts
  • Velcro straps on the inside and outside that are held on the outside of the hollow body or on the outer insert and hold the sandpaper or a smaller insert on the inside.
  • the holding element could also be dimensioned according to the grinding plate of the hand-held grinding machine and could have Velcro fastenings which serve as fastening means and encompass the side of the grinding plate.
  • the semicircular, shell-shaped hollow body 14 of the grinding device 10 can be attached to the holding element 12 releasably, for example by means of screws, or non-releasably, for example by means of rivets or glued.
  • the latter as well as the hollow body 14 are, however, preferably made from a piece made of plastic, but in principle they could also consist of another material (aluminum, steel, etc.).
  • two or more hollow bodies, preferably arranged parallel next to one another and having the same or different diameters, could be assigned to a holding element.
  • the sanding paper 45 is placed around a cylindrical workpiece 41 and releasably fastened around the workpiece 41 by a bandage 40 comprising this sanding paper 45.
  • This bandage 40 is provided on the inside and outside with a Velcro fastener tape, by means of which it holds the sanding paper 45 on the inside and on the one hand can be fastened in the opening 18 of the holding element 12 and on the other hand forms a self-fastening.
  • the sanding paper 45 with the abrasive grains on the inside is preferably placed approximately flush around this workpiece and the bandage 40 is then releasably attached by overlapping its two ends.
  • the holding element 12 can then be pressed with its semicircular opening 18 onto the bandage 40, while the vibrating grinding plate of the hand grinder is pressed onto the Velcro fastener tape 12 'and thus the workpiece 41 is ground or polished over its entire circumference in one operation, the hand grinder on the one hand using a high frequency executes this reciprocating feed movement and on the other hand it is also preferably guided by hand along the workpiece with a reciprocating and possibly superimposed pivoting movement. Above all, this allows pipes to be ground all around, which run along a wall and are difficult to access on the back.
  • FIGS. 4 and 5 also show two embodiment variants of grinding devices 43 and 50 provided with different shapes, each of which has a holding element 49, 52 provided with a Velcro fastener tape 49 ', 52' and a hollow body 48 each forming an opening 48 ', 54' , 54 have.
  • Abrasive paper can in turn be clamped into the respective opening 48 ', 54' by means of a Velcro fastener 46, 55 attached therein.
  • the grinding device 43 according to FIG. 4, which is rectangular in its cross section, is particularly suitable for grinding four-sided workpieces with rounded edges.
  • a further advantage with this grinding device 43 results from the fact that the radius 47 'formed by the sanding paper 47 which can be inserted into the opening 48' can be varied and can be precisely adapted to the actual rounding of the workpiece.
  • the grinding device 50 according to FIG. 5 is particularly suitable as a tool for woodworking for the purpose of machining a workpiece shaped according to the opening 54 '.
  • Other contours or ornament shapes than the one shown can be provided in the hollow body 54.
  • FIG. 6 shows a grinding device 30 which has only a hollow body 34 and a holding element 32 connected to it and designed as a handle. Otherwise, the hollow body 34 also has an approximately semicircular cylindrical opening 35 and an adhesive Velcro fastener tape 36 is also attached in it, which serves as a fastening means for the sandpaper. With this grinding device 30, a cylindrical workpiece can be polished, cleaned or ground by hand.
  • the holding element 32 and the hollow body 34 with the opening 35 could also be made in one piece or a separate handle could be provided, to which a holding element, as shown, for example, in FIG. 4 or FIG. 5, can be attached.
  • the invention is not limited to the exemplary embodiments explained.
  • the hollow bodies could be provided such that their inside is designed directly as a tool, for example by being coated with an abrasive.
  • the fasteners provided also do not have to be exclusively Velcro fasteners.
  • Self-adhesive tapes or the like would also be conceivable.
  • hook-and-loop fasteners are those which are available on the market and usually have, on the one hand, tapes provided with a large number of loop-shaped threads and, on the other hand, mushroom-shaped or hook-shaped threads of tapes or nonwovens engaging in them.
