Definitions
- the invention relates to a Elektrohandschleifma machine, in particular an eccentric grinder, the type defined in the preamble of claim 1.
- Rubber body on the underside of which an ' abrasive sheet containing the abrasive is interchangeably fixed as a wearing part.
- the rubber body is clipped over the outer edge of the grinding plate with an annular groove which is incorporated at the bottom of a central recess on the upper side of the rubber body facing away from the sanding sheet.
- the abrasive carrier there called abrasive plate, is plate-shaped and by means of screws on the
- the abrasive backing consists of a rigid top plate and a bottom plate made of soft material.
- an abrasive sheet containing abrasive grain is releasably secured by means of a surface adhesive connection.
- edge protection formed on the sanding plate protects the outer edges of the abrasive carrier made of soft material during the grinding process, particularly in the area of edges and gradations of the workpiece, and is very well protected by the protrusion of the circumferential protective member over the abrasive carrier cannot hit the workpiece at any time during the grinding process. This extremely reduces the wear on the abrasive carrier and significantly increases the service life of the abrasive carrier.
- the protective member protruding in the grinding plate level over the outer contour of the abrasive carrier can be an integral part of the grinding disc, which is preferably made of plastic, or can be attached to the grinding disc as a separate component in the form of a circumferential strip.
- the protective member partially overlaps the abrasive carrier on its outer surface, wherein in the one-piece embodiment of the protective member with the grinding plate, a circumferential angle piece on the grinding plate with a circumferential leg projects axially beyond the underside of the grinding plate receiving the abrasive carrier.
- a circumferential strip is provided with a circumferential web which extends axially over the underside of the grinding plate.
- FIG. 1 excerpts of a longitudinal section of a
- FIG. 2 is an enlarged view of section II in Fig. 1
- Fig. 3 is the same representation as in Fig. 2 of another embodiment.
- the eccentric sander shown in detail in longitudinal section in FIG. 1 as an exemplary embodiment for a general electric hand-held grinder, which can also be designed as an orbital sander, for example, has an electric motor 11 accommodated in a housing 10, which has a grinding plate via an eccentric 13 fastened to its rotor shaft 12 14 drives.
- the grinding plate 14 is axially fixed to the eccentric 13 by means of a fastening screw 15 screwed in at the end and is supported on the eccentric 13 by means of a ball bearing 16 integrated in the grinding plate .14, while the rotor shaft 12 is mounted in the housing 10 by means of a ball bearing 17.
- a brake rubber 18 for braking the grinding plate 14 is designed such that it protects the housing 10 from damage at its largest diameter.
- a fan 20 is attached to the rotor shaft 12, which sucks in air from the underside of the grinding plate 14 via dust extraction holes 21 present in the grinding plate 14 and conveys it to an air outlet connection 22, to which a dust collector filter is usually connected.
- an abrasive carrier 23 made of soft material, preferably rubber, is releasably attached to the underside of the 5 sanding plate 14 molded from plastic.
- the underside of the grinding plate 14 is coated with a surface adhesive 24, for example with a .
- Velcro adhesive sheet covered with a counter surface adhesive layer 25 covering the disc surface of the abrasive medium carrier 23, for example a nonwoven,
- Abrasive backing 23 produces.
- the abrasive carrier 23 in the same way as in the abrasive disc 14, built-in suction holes 26 are machined, when the abrasive carrier 23 is placed correctly on the abrasive disc
- abrasive carrier 23 On the underside of the abrasive carrier 23 facing away from the grinding plate 14 is an abrasive grit
- the abrasive carrier 23 is provided with edge protection.
- This edge protection has a protective member 30 running around the sanding plate 14, which protrudes in the plane of the sanding plate over the outer contour of the abrasive carrier 23 and partially overlaps the abrasive carrier 23 on its outer surface 231.
- FIG. 2 the detail II in FIG. 1 is shown enlarged with the sanding sheet 27 removed.
- the protective member 30 is an integral part of the grinding plate 14 and is injected when it is sprayed.
- -It has a rotating elbow 31 on which on the axially projecting the abrasive carrier 23 receiving underside of the grinding disc 14 with a "circumferential leg 311 and thus the
- Outer surface 141 of the grinding plate 14 partially overlaps.
- the protective member 30 is a circumferential strip 32 fastened to the grinding plate 14 and made of an elastic material, preferably rubber.
- the strip 32 is clipped onto the circumferential outer edge 141 of the grinding plate 14 and, with a circumferential web 321 also extending axially and projecting over the underside of the grinding plate 14, partially overlaps the outer surface 231 of the abrasive carrier 23.
- the strip 32 is fixed on the grinding plate 14 by a tongue / groove connection, for which incorporated a circumferential groove 34 in the A.ußenrand 141 of the grinding plate 14 and at the '141 A.ußenrand the facing surface of the bar 32 has a projecting, circumferential Spring 35 is formed, which is pressed into the groove 34 in a positive and non-positive manner.
