Definitions

  • the invention relates to a hand-held grinder with a drive motor and a grinding or polishing tool driven in a swinging manner.
  • hand grinders are known as so-called orbital sanders and are widely used. They are used, for example, to prepare an area to be subsequently covered with paint or the like.
  • the vibrating plate is driven with the help of an electric motor and an intermediate eccentric, and it usually carries an exchangeable sanding sheet.
  • the swinging movement is either straight and forth or in an orbital movement / ie the back and forth movement is still superimposed on a transverse movement.
  • the oscillating plate performs a movement, at least in the longitudinal direction, which is of the order of about one centimeter.
  • the front edges of the swivel plate must therefore be kept at a sufficiently large distance from other surfaces running transversely to the workpiece surface being processed. This is especially true if one of these surfaces is a sheet of glass.
  • oscillating grinders for example glass retaining strips and inner edges converging at right angles in window frames, cannot be grinded at all or at least quite inadequately. Grinding right into the corners is not possible anyway.
  • the object of the invention is therefore to develop a hand-held grinder of the type described above in such a way that it grinds surfaces down to en Let the inside edges or similar be subjected to difficult sanding work for spatial reasons.
  • the hand grinder is designed in accordance with the preamble of claim 1, in accordance with the characterizing part of this claim.
  • This hand-held grinder adheres to the principle of the vibrating driven grinding or polishing tool which is advantageous per se.
  • the grinding or polishing tool of this hand grinder performs a swiveling movement in which it oscillates about an axis fixed to the device, the swivel angle being kept relatively small, but instead being operated at a high frequency.
  • This different type of oscillating movement of the grinding or polishing tool allows a completely new shaping of the tools, in particular as far as the working surface of the grinding or polishing tool is concerned. Of course, this does not preclude the use of conventionally shaped grinding or polishing tools.
  • the grinding or polishing tool can be designed such that it has a tapering corner region, the side edges of which form an angle of less than 90 °, so that this corner region is preferably ground from corners is possible which is not possible with the previously known grinding tools.
  • the grinding tool has free-standing side edges adjoining the corner, so that grinding of inner longitudinal edges is also possible with such a grinding tool according to the invention in that the grinding tool with the side edges adjoining the corner can be guided against these inner longitudinal edges.
  • the swivel axis also cuts the grinding tool in a central region, since then the convex side surfaces can be designed according to the invention in such a way that in their outermost region they have no radial movement with respect to the swivel axis but only perform a movement perpendicular to the radial direction, which results in the grinding tool resting extremely quietly on an inner longitudinal edge.
  • Another advantage of a swivel axis arranged in a central region of the grinding tool is that unbalance and thus vibrations of the entire hand-held grinding device can be avoided.
  • this deflection is of course less, the smaller the distance of the free end of the grinding or polishing tool from this axis fixed to the device.
  • the use of grinding or polishing tools of different sizes can influence the deflection of the tool during the oscillating movement. It is easily possible to keep the rash so small that it is barely visible to the naked eye. One then has the impression that the grinding or polishing tool does not move at all, even though it of course does its job perfectly. In this case in particular, you can work right down to the inside corner.
  • this geometric axis primarily relates to the geometric axis about which the grinding or polishing tool is pivoted back and forth in the direction of rotation. It is obvious that this geometric axis does not have to be arranged centrally to the working surface of the grinding or polishing tool and, for example, in the case of a double-edged shape or the like.
  • a geometric axis offset in the longitudinal direction of the tool has the advantage that the two can be followed the opposite ends of the tool ends projecting vibrations of different widths.
  • the oscillating pivoting movement of the grinding or polishing tool can be achieved with the aid of a conventional drive motor, for example an electric motor, and an eccentric driven by this, which is why the drive is not shown and described in detail.
  • the eccentric transmits its rotational movement to a rotatably mounted rocker, the geometric axis of rotation of which can also be the geometric axis for the angular, oscillating movement of the grinding or polishing tool.
  • the eccentric engages in the end remote from the mentioned bearing axis of the rocker, in particular the longitudinal axis of the rocker approximately parallel to the longitudinal axis of the eccentric drive shaft b between. the motor drive shaft runs t.
  • any other motor is of course also possible, which can drive such a swing arm or a comparable element pivoting back and forth, for example.
  • the known orbital sanders work at a frequency in the order of ten thousand vibrations per minute. It makes sense to have the grinding or polishing tool of the hand-held grinding device according to the invention vibrate at least in this order of magnitude.
  • the swivel frequency of the grinding or polishing tool is approximately ten thousand to twenty-five thousand oscillations per minute. This means that the frequency of this tool can be considerably higher than in the known prior art. As a rule, however, it will be the case that, particularly in the case of electronic frequency control, smaller grinding or polishing tools tend to reach the upper limit of this range than comparatively larger ones. Otherwise, the high frequencies will be used primarily for polishing. So it is easily possible to use this hand-held grinder to polish scratches from sensitive windows, for example, which can occur when the wiper of a car is operated with the window dry, but covered with dust or sand grains.
  • the swivel angle should not exceed a certain maximum value with regard to its maximum deflection. In principle, there are no limits downwards. From this point of view, it is considered appropriate to keep the pivoting angle of the grinding or polishing tool in a range of about 0.5 ° to 7 °. It is easily conceivable, but with a certain effort, to make the pivoting angle changeable.
  • a particularly preferred variant of the invention features is characterized in that a drive shaft having the device-fixed axis or which can be driven by means of a motor and an intermediate gear in an oscillating manner in the direction of rotation.
  • the output shaft of the motor thus performs a rotary movement as usual, which, as said, is preferably a high-speed electric motor.
  • the gearbox converts this rotating movement into a reciprocating angular swivel movement of the frequency mentioned.
  • the grinding or polishing tool is positively connected to the drive shaft, the drive shaft in particular having a polygonal or star-shaped cross section and the tool having a receptacle or an opening with a corresponding cross section.
  • the drive shaft in particular having a polygonal or star-shaped cross section and the tool having a receptacle or an opening with a corresponding cross section.
  • the grinding or polishing tool is preferably arranged concentrically to the drive shaft.
  • it is primarily intended for a grinding or polishing tool with a polygonal shape, for example with a triangular or quadrangular shape, the longitudinal edges being straight or also from can be concave or convex.
  • FIG. 7 of the drawing very special edge shapes are also easily possible.
  • the grinding or polishing tool therefore has a non-circular, in particular approximately polygonal, working surface.
  • Another variant of the invention is characterized in that the grinding or polishing tool is arranged eccentrically to the drive shaft and in particular has an essentially rod-shaped or strip-like shape. This tool is particularly suitable for processing small and smallest areas or for inside edges and inside corners.
  • Special tasks can be accomplished with a grinding or polishing tool, which is advantageously characterized in that only the free end area of this tool has a grinding or polishing surface.
  • a further development of the invention provides that the free end or the free end area is angled and only the angled part has a grinding or polishing surface, as can be seen in FIG. 6 of the drawing.
  • This tool can be used to mechanically handle grinding and polishing tasks for which there has never been a hand tool.
  • Another particularly advantageous embodiment of the hand-held grinder according to the invention provides that the housing extends essentially laterally in the direction away from the pivot axis, that is to say that, for example, the pivot axis lies in a front gear part of this housing and this then moves away from the pivot axis in one direction extends.
  • the housing has a longitudinal axis which encloses approximately a right angle with the pivot axis.
  • the longitudinal axis of the housing coincides with the axis of rotation of the rotating motor, so that the axis of rotation of the rotating motor is also approximately at a right angle to the pivot axis.
  • Such an embodiment has the advantage that a particularly simple and advantageous embodiment of the rotating Movement in an oscillating motion converting gear is possible.
  • this embodiment has the advantage that the housing, in particular the part of the housing which accommodates the rotating motor, does not hinder working in a corner, since this lies approximately opposite the corner region of the grinding tool and thus makes it optimally visible to an operator.
  • the housing containing the rotating motor at the same time is also particularly advantageous to design the housing containing the rotating motor at the same time as a handle for an operator.

  • the tool 3 has an approximately square work surface 5.
  • the tool 3 has a triangular shape. With the shape according to FIG. 2 it is easier to get into tapered corners. Other polygonal shapes of the tool 3 are also conceivable. In some applications, an elliptically shaped plate can also be used or the working surface 5 can be bulged.
  • the connecting lines between the corner points are shown arched. However, in order to work better in corners, these lines can be straight in the corner area.
  • an abrasive paper 6 or the like may be attached on the working surface 5 of the tool 3.

  • the drive shaft 4 can be inserted through the polygonal hole 11 until the shoulder 14 of the drive shaft 4 rests on the supporting or supporting body 8.
  • the drive shaft 4 is formed in the area that protrudes through the body 8, corresponding to the polygonal hole 11, so that a positive connection between the drive shaft 4 and the support or support body 8 is formed.
  • the body 8 is pressed against the shoulder 14 by the nut 12, which is screwed onto the thread 15 located at the end of the drive shaft 4.
  • the drive shaft 4 has a particularly central bore 16 for dust extraction. So that the dust extraction can not only take place centrally, grooves 17 are machined from the bore 13 in the radial direction on the working surface 5 of the tool 3. In order to allow suctioning from the edge in the embodiment according to FIG. 4, holes 18 are provided in the sandpaper or the like.

Its swing arm 21 is angled and has a fastening surface 22 which carries a grinding body 23. Only this one example is shown in the drawing. However, it is easy to see that the grinding body 23 can be arranged in any angular position or parallel to the swing arm 21. The length of the swing arm 21 can be chosen so that the grinding body 23 protrudes far beyond the edge of the gear housing, so that only the narrow swing arm 21 has to be guided to the limited working area.

Abstract

Etant donné que le meulage avec les meuleuses connues, telles que les meuleuses d'angle, meuleuses à bande ou ponceuses vibrantes pose des problèmes impossibles à résoudre, comme le meulage de bords intérieurs formant un angle entre eux, par exemple dans des listels de retenue de vitres de fenêtres et de portes, on a développé une meuleuse portative dont l'outil à meuler ou à poncer (3, 20, 30) effectue un mouvement d'oscillation qui, au contraire de l'état connu de l'art, se fait autour d'un axe fixe de l'appareil (29) avec un angle de pivotement minime compris de préférence entre 0,5o et 7o et avec une fréquence élevée de pivotement comprise entre dix mille et vingt cinq mille vibrations par minute. Ce mouvement différent d'oscillation permet de donner à l'outil à meuler ou à poncer presque n'importe quelle forme. En outre, le meulage ne doit pas obligatoirement se faire avec la surface de l'outil (3) transversale, en particulier perpendiculaire, par rapport à l'axe géométrique (29), mais on peut également utiliser une surface presque parallèle à la première, ou même arquée. On peut même imaginer d'utiliser l'ensemble de la région des coins de l'outil à meuler ou à poncer. De préférence, comme dans la plupart des meuleuses couramment utilisées aujourd'hui, la poussière du meulage est aspirée. Il est en outre possible de former dans la ponceuse, de manière très avantageuse, des poches ou similaires pour contenir une pâte abrasive pour polir, de même que pour une pâte-émeri. Dans la mesure où l'on utilise du papier-émeri, de la toile abrasive ou similaire, ceux-ci peuvent être fixés à l'outil ou échangés selon un procédé connu ou selon le procédé décrit ci-dessus.
