Definitions

  • the invention relates to an attachment for an angle grinder, with an eccentric head which can be screwed onto its output spindle and which acts on a tool carrier via an eccentrically arranged ball bearing, the freedom of movement of which is flexible by a flexible linkage device attached to the housing of the angle grinder and a reciprocating movement in accordance with the eccentricity and is limited to an overlapping pivoting movement around the flexible point of the articulation device.
  • the AEG company has been selling the SS 707 and SS 717 orbital sander types since 1978, in which the tool carrier, which has an eccentric ball bearing, is flexibly articulated by four cylindrical rubber buffers arranged in a rectangle to parts rigidly connected to the drive machine housing in such a way that a rotational movement of the tool carrier is prevented is and this only performs a small oscillating circuit movement according to the eccentricity of the ball bearing.
  • These known orbital sanders are designed as attachments for manual drive machines (see catalog AEG DIY system, February 1978). However, they are not suitable for grinding surfaces along edges or in narrow corner areas.
  • the output spindle is provided with an eccentric, which acts via an eccentrically arranged ball bearing on a strip-shaped tool carrier, the freedom of movement by a bolt attached to the grinder housing, which engages in an elongated hole of the strip-shaped tool carrier , is limited to a to-and-fro movement in the longitudinal direction of the ledge and to an overlapping pivoting movement around the bolt, so that the tool carrier describes an elliptical movement path at its front free end.
  • the tool carrier carries there a rectangular sanding pad at its front free end.
  • this known angle hand grinder is also suitable for sanding and fine sanding on longitudinal edges and in corners.
  • the elliptical, circular movement of the individual abrasive grain enables a very fine sanding, the sanding sheet being worn there almost uniformly over the entire surface.
  • this known device must be purchased as a single device, since its eccentric head and the tool carrier linkage are integrated into the basic device and are therefore not designed as an attachment.
  • the invention has for its object to provide a generic attachment for angle grinders such that it can be used for all types of angle grinders available on the market and allows inexpensive production of a set of different tool carriers.
  • the outer ring of the ball bearing is arranged eccentrically in the rotating eccentric head and a central internal threaded bushing is fastened in the inner ring
  • the articulation device consists of a tab that can be screwed onto a handle screw hole of the angle grinder and that is flexibly connected to the tab , at the lower end of the threaded bushing, radially projecting cantilever part and that the tool carrier is a structurally separate from the articulation device and the eccentric, which is interchangeable.
  • the invention provides a number of advantages.
  • the attachment can be attached to almost all commercially available angle hand grinders via the screw-on bracket, since on the one hand the thread of the output spindle of such devices is standardized and the threaded holes on the head of the known angle grinder on both sides for screwing on additional handles are used for the flexible articulation in the invention.
  • a further decisive advantage is that when the tool holder is changed, the eccentric head including the ball bearing and also the flexible linkage device remain on the angle grinder and therefore only the tool holder - for example when worn against a new one - or against another type of tool holder must be replaced.
  • fingers can be protruding grinding plates or tool carriers in the form of an arch triangle or, preferably, elongated hexagonal tool carriers, in which the front and rear corners each have an angle of 90 °.
  • a grinding plate largely combines the advantages of an arched triangular grinding plate with those of a grinding plate protruding in the form of a finger.
  • the cantilever part can consist of a cup which largely encloses the eccentric head and which protrudes toward the tab and which can be clamped together with the tool carrier by means of a single cap screw on the internally threaded bushing.
  • Fig. 1 shows an angle grinder 1
  • the output spindle 2 is provided with a standardized thread and has two threaded holes 3, 4 provided on both sides of the angle grinder head for optionally screwing on additional handles.
  • the attachment consists of an eccentric head 5 which can be screwed onto the output spindle 2 by means of a threaded bore 6 and rotates with the latter.
  • the eccentric head 5 carries in an eccentric receptacle 8 with respect to the axis 7 of the threaded bore 6 the outer ring 9 of a deep groove ball bearing 10, on the inner ring 11 of which an internally threaded bushing 12 is clamped by means of a cap screw 13 screwed into the internally threaded bushing 12 from above.
  • the outer ring 9 of the ball bearing is clamped to the eccentric head 5 by a plurality of pan head screws 14 distributed over the circumference.
  • the tool carrier 16, which is designed as a grinding plate, can be connected to the eccentric ball bearing 10 by means of a cap screw 15 inserted into the internally threaded bushing 12 from below.
  • the attachment is provided with a flexible articulation device 17, which is shown only schematically in FIG. 1 and in constructive detail in FIGS. 2 to 4.
  • the articulation device 17 comprises a cantilever part 18 which can be clamped directly onto the end face of the internally threaded bushing 12 and between whose radially projecting projection 19 and a tab 20 an elastic rubber buffer 21 is clamped.
  • the tab 20 is directed approximately perpendicular to the tool carrier 16 and is provided with an elongated hole 22 and is fastened by means of a cap screw to the screw hole 4 lying rearward in FIG. 1.
  • a group of different cap screws 23 with washers 24 is assigned to the attachment.
  • the cantilever part 18 of the flexible articulation device 17 consists of a cup 25, which largely encloses the eccentric head 5, on the inner bottom of which a hexagon receptacle 26 is attached for the lower end of the threaded bushing 12 designed as a congruent hexagon head 27.
  • a hexagon receptacle 26 On the outside of the cup 25 there is provided the radially protruding projection 19, which, when the attachment is mounted, moves backwards, i.e.
  • the transverse component of the circular movement path 30 is, however, suppressed by the rubber buffer 21 at the rear end of the tool carrier 16, so that the reciprocating movement of the grinding plate overlaps a pivoting movement around the articulation point 33 and the grinding plate in its front region 34 has an elliptical movement path 35 executes, which is, however, shown greatly enlarged in Fig. 5. Due to the swiveling movement, the rubber buffer is minimally loaded for compression or expansion, which is indicated by the short arrows on the front side S of the buffer. The buffer is not subjected torsion.
  • the tool carrier or grinding plate 16 shown which has the shape of an elongated hexagon and in which the screwing point 36 is offset on the longitudinal axis L next to the center M of the grinding plate, there is an eccentricity of 0.5 millimeters in the front area 34 of the grinding plate an elliptical trajectory, the short axis is 1 millimeter and the long axis is about 2 to 3 millimeters.
  • the hexagonal tool carrier 16 has at its two opposite ends in the longitudinal axis L each at a right angle R, so that with such a grinding tool in an optimal manner along the edge and in the corner of a workpiece 37, which is, for example, a drawer acts, can be worked.
  • the grinding plate is provided on both sides of its longitudinal center M with screw-through openings 38, so that when the front area 34 wears out, the tool carrier can be converted into a position turned through 180 ° and screwed on again.
  • the tab 40 here has at its lower, forwardly bent end a downwardly directed bolt 41 which engages in a horizontal elongated hole 42 in the shoulder 43 of the collar part 44.
  • the elongated hole 42 has a width equal to the diameter of the bolt 41, so that the bolt 41 acts as a hinge axis.
  • the length of the elongated hole 42 should be significantly greater than the sum of the diameter of the bolt 41 and the stroke length according to the double arrow 31, for example 20 millimeters, since this facilitates the adaptation of the attachment to the respective angle grinder devices.
  • the articulation device 45 consists of an approximately parallel to the plane of the tool carrier 16 Connecting member 46 which is pivotally mounted on the cantilever 47 and the tab 20 about axes perpendicular to the plane of the tool carrier.
  • Connecting member 46 which is pivotally mounted on the cantilever 47 and the tab 20 about axes perpendicular to the plane of the tool carrier.
  • a hinge sleeve 48 is screwed onto the tab 20 and a sleeve 49 is inserted into the collar part 47.
  • the articulation axes 50, 51 are here made in one piece with the connecting member 46 consisting of round material, which thus has an overall U-shape.
  • ball bearings can also be provided to reduce the bearing friction.
  • the invention is not restricted to the exemplary embodiments shown. Rather, the attachment can be assigned different tool carriers with tools for grinding, polishing, corner grinding, scraping or slitting.
