Definitions

  • the known grinding tool has a grinding plate which tapers towards one end and is rounded at the opposite end.
  • This grinding plate can be connected by means of a plurality of mounting holes in different positions with a receptacle which is driven to oscillate.
  • the grinding tool thereby performs oscillatory movements, which are formed as approximately linear reciprocating movements transversely to the longitudinal axis of the grinding device.
  • the oscillation of the grinding plate should apparently be oscillated back and forth about a device-fixed pivot axis, without, however, explaining this embodiment in detail.
  • Another grinding tool known from EP-B-0 244 465 has an oscillation drive by means of which a drive axle is pivoted back and forth at high frequency and with a low pivoting angle.
  • the grinding tool is connected in the middle of its preferably triangular shaped with convex outwardly curved side edges grinding surface with the drive axis.
  • the grinding tool thus performs a pivoting movement about the drive axis, wherein the center of the pivoting movement is in the drive axle.
  • the corner areas undergo the strongest deflection, being swung back and forth on circular segments. Also at the preferably outwardly convex curved side edges results in such a movement.
  • the known grinder has proven to be extremely advantageous to perform difficult grinding or polishing work in hard to reach places, which can be worked through the nature of the drive and by the movement of the grinding tool particularly advantageous along the inner longitudinal edges to corner areas.
  • the invention is therefore an object of the invention to improve a grinding device according to the aforementioned type such that the abrasive effect is increased in the central region of the grinding tool, with a working along the inner longitudinal edges, however, should still be possible.
  • the object of the invention is achieved in a grinding apparatus according to claim 1.
  • a particularly high grinding performance is ensured by the oscillating drive of the grinding device to a device-fixed pivot axis with a pivot angle between 0.5 and 7 ° and with a frequency greater than 5000 vibrations / minute.
  • the grinding plate is connected via a slot with the drive axle, an optimal adaptation to the respective grinding task allows, so that vibrations can be largely avoided and at the same time the highest possible grinding performance is guaranteed.
  • the fastener may in this case be formed, for example, as a screw which can be screwed into a threaded blind hole of the drive axle.
  • the grinding plate is triangular in shape and has convex outwardly curved side edges.
  • the outer end of the drive shaft 16 is widened by a flange 18, to which a triangular grinding tool 22 by means of a generally designated by the numeral 25 recording, which is located outside the geometric center of the grinding tool 22, can be attached.
  • the structure of the grinding tool 22 is known per se.
  • the grinding tool 22 comprises a grinding plate designated as a whole by the numeral 24, on whose underside remote from the drive axis 16 either an abrasive material can be applied directly, which is the case, for example, with diamond-coated grinding plates.
  • the underside of the grinding plate 24 may also, as shown in the drawing, be provided with a Velcro material 32 so that the Sanding plate 24, an abrasive, such as an abrasive paper piece, which is provided at its top with a suitable fabric material, can be easily pressed so as to allow an easily detachable connection between a releasable abrasive and the grinding plate 24.
  • the grinding tool 22 consists either of grinding plate 24 with abrasive coating on the underside or of grinding plate 24 and associated abrasive that can be releasably attached to the underside of the grinding plate. It is understood that instead of a connection possibility by means of a hook and loop fastener, for example, an adhesive connection with a releasable adhesive tape can be considered.
  • the grinding device according to the invention now differs from a grinding device according to the prior art by the receptacle 25, which is shown in FIGS. 1 and 2.
  • the receptacle 25 has in this embodiment, a slot 26 which extends from the geometric center I of the grinding plate 24 on an imaginary connecting line to the opposite corner 42 in the direction of the adjacent side edge 41 out. Through this slot 26, a fastener in the form of a screw 38 by a washer 36 with its thread 34 in a threaded blind hole 20 of Drive axle 16 are screwed.
  • the attachment opening is formed as a slot 26, so the geometric location of the connection between the grinding plate 24 and the drive axle 16 can be adjusted, so move from the geometric center I out to a remote from the opposite corner 42 end position II, if the greatest possible deflection in the opposite corner region 42 and a stronger abrasive action in the middle region is desired, or else to shift in the direction of the opposite corner 42 to position III, in order to achieve a lower abrasive effect in the region of the opposite corner 42.
