Definitions
- the invention is based on a hand-held grinding tool with a motor and a gear, which drive an oscillating drive means by a deflection angle, which moves a grinding belt attached to it back and forth.
- the grinding belt adapts to the radius of the object.
- a motor-driven grinding apparatus is known from DE 34 47 828 AI, which is used for grinding, smoothing and polishing preferably round rods and tubes.
- This uses an open grinding belt which is looped around the workpiece and which is held with its two ends in two clamping or clamping devices of the grinding apparatus.
- a motorized with The rectified rotational movement of the drivable gear sets the two clamping and tensioning devices and thus also the grinding belt in an alternating, synchronously opposite movement via a movement device, which pulls the grinding belt over the workpiece.
- a hand-held grinding tool according to the invention with the features of claim 1 or claim 8 has the advantage over the above that * a simple change of the grinding belt is possible.
- the closure according to the invention on the sanding belt eliminates the need to cut and glue the sanding belt, or loosen and fasten the ends to a clamping or tensioning device.
- the loosening or fastening of the sanding belt takes place, for example, in the case of a Velcro fastener by simply pressing on it, without further steps being necessary.
- the Velcro fastener offers sufficient security against unintentional loosening.
- the closure engages with the drive means.
- the sanding belt is first placed around the object to be processed and then pressed with its two ends against the drive means, the counterpart on the drive means ke are arranged for Velcro of the sanding belt.
- the grinding belt after it has been led around the object to be processed, to guide the entire drive means and to connect the two ends of the grinding belt between the drive means and the object to be processed directly by means of a Velcro fastener.
- the drive means is an oscillating head, which in particular has the shape of a wheel. This makes it possible in a simple manner to guide the grinding belt around the oscillating head and either on. to fix it or its two ends, as described above, between the oscillating head and the 15th to be machined . Join the workpiece together.
- the transmission has a beveled drive shaft on its end face facing away from the motor, on which a pin is arranged eccentrically,
- the closure is formed at the first end and at the second end of the grinding belt. Compared to an arrangement within the grinding belt, the entire length of the sanding belt can be used. This serves to process round objects with very different diameters with the same sanding belt.
- Another embodiment of the invention provides that the grinding belt is arranged with its first end on the drive means and its second end is connected to a handle.
- the grinding belt can be easily changed.
- an elastic element is arranged between the second end of the grinding belt and the handle.
- the first end of the grinding belt is rotatably attached to the drive means. As a result, it is possible that the user does not have to assume unnatural hand and arm positions in the case of locations which are difficult to reach and which are to be processed.
- the drive means is a machine insert.
- the grinding tool can be used universally, since inserts other than the grinding belt can also be coupled to the machine insert. Further advantageous embodiments of the invention are the subject of the dependent claims.
- Fig. 1 shows a first embodiment of a hand-held
- FIG. 2 shows a section through a second embodiment of a ' grinding tool with an abrasive belt
- FIG. 1 shows a hand-held grinding tool 1 which has a drive means 2 in the form of an oscillating head 5.
- the driving head 5 is driven by the means described in FIGS. 2 and 3 for a further exemplary embodiment.
- the oscillating head 5 is set into an oscillating movement. It swings about an axis 16.
- a grinding belt 3 is guided around the oscillating head 5.
- the grinding belt 3 has a closure 4 through which the first end 11 is detachably connected to the second end 12 of the grinding belt 3 to form a ring.
- a 'Velcro 4 will be described by way of example as a closure. 4
- the Velcro fastener 4 is so ordered that it lies between the oscillating head 5 and an object 17 to be machined (FIG. 2).
- FIGS. 2 and 3 show a second exemplary embodiment of a hand-held grinding tool 1 according to the invention.
- this second embodiment works like the first embodiment shown in FIG.
- the same or equivalent parts are provided with the same reference numerals. Only the differences from the first exemplary embodiment described above are discussed below.
- the oscillating head 5 is moved by a gear 7, which is mounted in a housing 18 of the grinding tool 1 and by a motor 6 is driven.
- the drive is not essential for the invention, so that a detailed description of these elements is dispensed with.
- a drive shaft 8 is formed at the end of the transmission 7 and rotates about a longitudinal axis A of the grinding tool 1.
- the rotation of the drive shaft 8 is converted into an oscillating movement by a deflection angle D along the double arrow C by a pin 9 arranged eccentrically on it and engaging in a link guide 10 on the oscillating head 5. This takes place in that the pin 9 is arranged eccentrically to the longitudinal axis A along a pin axis B.
- the more detailed configuration is shown in Fig. 3.
- the drive shaft 8 is delimited by an end surface 20 tilted against the longitudinal axis A.
- the pin 9 is arranged eccentrically to the longitudinal axis A on this end surface 20.
- the pin axis B formed by the pin 9 extends in its extension through the axis 16 about which the oscillating head 5 oscillates.
- the deflection angle D is defined by the distance between the pin axis B and the longitudinal axis A along the end surface 20. ' niert.
- the value of the deflection angle D corresponds to the amplitude at the oscillation of the "vibrating head 5 about the axis 16 along the double arrow C (FIG. 2 ') is reached.
- the pin 9 is rotatably supported by a bearing 19 in the connecting link guide 10 3, the representation of the grinding belt 3 has been omitted due to the clarity.
- the abrasive region 21 on the object 17 ' is the area which faces away from the grinding tool. 1
- the grinding belt 3 is moved back and forth by the oscillating movement of the oscillating head 5 over the grinding area 21, thereby making it one
- FIG. 4 shows a third exemplary embodiment of a hand-held grinding tool 1 according to the invention. Are here too
- the first end 11 of the grinding belt 3 is rotatably attached to the drive means 2.
- the drive means 2 is formed on a machine insert 15.
- a handle 13 is attached via an elastic element 14.
- a spring 14 is described as an elastic element 14.
- any other elastic elements 14 can also be used.
- the handle 13 In order to be able to process an object 17 (not shown) with such a grinding tool 1, the handle 13 is guided around the object 17, so that the grinding belt 3 on the grinding
- the grinding belt 3 does not have to be released from the grinding tool 1. This ensures rapid processing of the object 17. It is also possible to use the grinding belt 3 over a wide range of its length, depending on the area in which the grinding belt 3 is placed around the object 17 'by means of the handle 13. As a result, the grinding belt 3 can be used longer without having to be replaced. This saves costs for the user. This effect is further enhanced if the grinding belt 3 is designed as a grinding surface on both sides. Due to the rotatable mounting of the first end 11 on the drive means 2, the one shown in FIG.
- An abrasive cloth tape, abrasive fleece, polishing tape, saw wire, brush tape or eraser tape In addition to the use of a Velcro fastener 4 on the sanding belt 3, it is equally possible to use push buttons, clamps, screws, hooks or similar connecting means.
- a grinding tool 1 can be processed, for example, with a grinding tool 1 according to the invention:
- a railing in particular stair railing, a garden fence with a round or semicircular profile, turned table and chair legs.
- the following machining operations can also be carried out: rounding edges of furniture, machining small parts using stationary grinding and polishing equipment, erasing, removing adhesive residues, sawing circular sections and sawing pipes with saw wire.
