Definitions

  • the invention relates to a hand-held grinder with a drive motor and a grinding or polishing tool driven with it in a swinging manner.
  • hand grinders are known as so-called orbital sanders and are widely used. They are used, for example, to prepare a surface to be subsequently covered with paint or the like.
  • the vibrating plate is driven by an electric motor and an intermediate eccentric, and it usually carries an exchangeable sanding sheet.
  • the oscillating movement takes place either in a straight line back and forth or in an orbital movement, i.e. H. the back and forth movement is superimposed on a transverse movement. Overall, the oscillating plate performs a movement, at least in the longitudinal direction, which is of the order of about one centimeter.
  • the end edges of the vibrating plate must therefore be kept at a sufficiently large distance from other surfaces running transversely to the workpiece surface currently being machined. 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.
  • a grinding device which, by oscillating movement of an arm, moves a grinding tool held at a front end of this arm back and forth along at least a substantially straight line.
  • the grinding tool can be rectangular or round.
  • the frequency of this movement is in the range between 3,000 and 4,000 / min and the displacement is in the range of a few cm and thus in the range of conventional orbital sanders, so that grinding of the inner longitudinal edges is also only possible to a limited extent.
  • US Pat. No. 3,160,995 shows a grinding tool designed in the form of a segment of a circle, which runs under a cover which also has the form of a segment of a circle.
  • the swiveling axis of the grinding tool lies in the center of the circle and the angle of the corner of the grinding tool coinciding with the center of the circle is less than 90 °, while the angle of the cover above it at the corner coinciding with the center of the circle is 90 °.
  • the grinding tool can thus be pivoted out and out under the cover about its pivot axis coinciding with the center of the circle, without protruding with its side edges under the cover.
  • the first object of the invention is therefore to develop a hand grinder so that it can be used to grind surfaces down to converging inner edges or the like for spatial reasons difficult grinding work.
  • the hand grinder with a drive accommodated in a housing and with a grinding tool which has a work surface with exposed side edges suitable for grinding inner longitudinal edges and in particular at least one grinding corner area and which therefore drives the drive around a device-fixed pivot axis is driven to oscillate with a small pivoting angle is designed so that the pivot axis cuts the grinding tool, in order to give it a rotary pivoting movement, in a central region, that the pivoting frequency of the grinding or polishing tool is approximately 10,000 to 25,000 oscillations / min and that Swivel angle is about 0.5 ° to 7 °.
  • This hand-held grinder adheres to the advantageous principle of the oscillating driven grinding or polishing tool.
  • the grinding or polishing tool of this hand-held grinder performs a swiveling movement in which it oscillates about an axis fixed to the device, the pivoting angle being kept relatively small but being worked at a high frequency.
  • the second object of the invention is to be seen in this different oscillating pivoting movement of the grinding or polishing tool for a completely new shaping of the grinding or polishing tools, in particular what the working surface of the grinding or polishing tool.
  • This task is achieved in the case of a grinding tool in which the grinding tool is driven to oscillate about a pivot axis fixed to the housing, with a working surface which has exposed side edges which are suitable for grinding internal longitudinal edges and which run towards one another to form at least one grinding corner region solved that the exposed side edges suitable for grinding inner longitudinal edges are convexly bent outward following the abrasive corner area, so that inner longitudinal edges can be machined particularly well.
  • a grinding tool with a working surface which has exposed side edges suitable for grinding internal longitudinal edges and running towards one another to form at least one grinding corner region is designed such that the exposed ones are suitable for grinding internal longitudinal edges Enclose side edges in the grinding corner area at an angle of ⁇ 90 °, so that with this corner area it is preferably possible to grind corners, 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 can be guided with these side longitudinal edges adjoining the corner.
  • a hand-held grinder with a drive accommodated in a housing and with a grinding tool which, due to at least one grinding corner area, has a non-circular work surface with exposed side edges suitable for grinding inner longitudinal edges, and which has a small swivel axis due to the drive Swivel angle is driven in an oscillating manner and with a grinding tool according to the invention if the pivot axis also cuts the grinding tool in a central region, since imbalances and thus vibrations of the entire hand-held grinding device can be avoided by the pivoting axis cutting this in a central region of the grinding tool.
  • the convex side surfaces can then be designed according to the invention such that in their outermost region they do not execute any radial movement with respect to the pivot axis, but only a movement running perpendicular to the radial direction, which results in the grinding tool resting extremely quietly on an inner longitudinal edge .
  • a high ablation rate is achieved due to the high frequency, while, in contrast to the orbital sander, the small swiveling angle causes only a slight deflection of the grinding or polishing tool, specifically across the axis of the device. At a certain swivel angle, this deflection is of course less, the smaller the distance of the free end of the grinding or polishing tool from this fixed axis. In this way, 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. You then have 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.
  • an axis fixed to the device this relates primarily 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 in the center of the working surface of the grinding or polishing tool and at 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 vibration deflections of different widths are obtained on the two tool ends protruding on opposite sides.
  • an axis for example a peg-shaped axis, on which the grinding or polishing tool is held and whose geometric axis runs through the tip of the pivoting angle.
  • the oscillating pivoting movement of the grinding or polishing tool can be achieved in a manner known per se with the aid of a conventional drive motor, for example an electric motor, and an eccentric driven by this, for which reason 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 running approximately parallel to the longitudinal axis of the eccentric drive shaft or the motor drive shaft.
  • any other motor is of course also possible, which can drive such a rocker arm or a comparable element to swing back and forth.
  • the known orbital sanders work at a frequency in the order of 10,000 vibrations / min. 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.
  • a preferred embodiment of the invention therefore provides that the pivoting frequency of the grinding or polishing tool is approximately 10,000 to 25,000 vibrations / min. This means that the frequency of this tool can be considerably higher than that of 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 mainly be used for polishing. So it is easily possible to use this hand grinder to polish scratches from sensitive windows, for example, which can occur if the wiper of a car is operated with a dry window that is 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 expedient to keep the pivoting angle of the grinding or polishing tool in a range from approximately 0.5 ° to 7 °. It is easily conceivable, but associated with a certain effort, to make the pivoting angle changeable.
  • a particularly preferred variant of the invention is characterized in that a drive shaft having or forming the device-fixed axis can be driven to oscillate in the direction of rotation by means of a motor and an intermediate gear.
  • 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.
  • a further embodiment of the invention is that 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 square shape, the longitudinal edges being rectilinear or also being 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.
  • the housing extends essentially laterally in the direction away from the pivot axis; that is to say, for example, that the pivot axis lies in a front gear part of this housing and then extends in one direction away from the pivot axis.
  • This has the particular advantage that when editing corners the grinding tool with a part opposite the housing with respect to the pivot axis can be inserted well into any corners, advantageously then the corner region of the grinding tool having an angle of ⁇ 90 ° should be arranged in the region of the grinding tool opposite the housing, so that this for the Operator is clearly visible and insertion of this corner area into a corner is not hindered by the housing itself, since this extends in the opposite direction with respect to the pivot axis.
  • the housing has a longitudinal axis which encloses approximately a right angle with the swivel 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 transmission which converts the rotating movement into an oscillating movement 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 as a handle for an operator.
  • the grinding device shown in Fig. 1 is equipped with a motor 1 housed in the housing.
  • a motor 1 housed in the housing.
  • the motor 1 is followed by a transmission 2, which is also housed in the housing.
  • the rotational movement of the electric motor is converted into an oscillating movement of a grinding or polishing tool 3.
  • the grinding or polishing tool performs a reciprocating wire movement around the geometrical axis 29, which is fastened to the device.

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.
