  • the machine 11 shown in the drawing for deburring workpieces 12 in the form of housing covers is equipped with two pairs of horizontally arranged plate brushes 16, 17 and 18, 19 for deburring the long sides 13 and 14 of the workpiece 12 as well as with a vertically arranged pair Disc brushes 20 and 21 are provided, which are used for deburring the top or bottom 22 of the workpiece 12. While the pairs of plate brushes 16, 17 and 18, 19 with a horizontal axis are arranged opposite one another in a region 23 of the machine stand (not shown), the plate brushes 20, 21 with a vertical axis are arranged in an adjacent region 24 of the machine stand. According to FIG.
  • a machine table 26 can be moved back and forth between these two areas 23 and 24 of the machine stand, on which the workpiece 12 can be clamped, which in this way processes on its longitudinal sides 13, 14 and on its top and bottom sides 22 becomes.
  • the reciprocating drive for the table 26 can be done in any known manner.
  • the plate brush pairs 16, 17 and 18, 19 are driven with their horizontal, parallel shafts 27 according to arrows A and B or A and B in opposite directions.
  • the disc brushes 20 and 21 are driven with their shafts 28 in opposite directions according to arrows C and D and also carry out a rotational movement superimposed on this inherent rotation in the direction of arrow E about an axis 31 which is parallel to and essentially centered between the parallel vertical axes of rotation the plate brushes 20, 21 is arranged.
  • the outer circular path and that of the shafts 28 of the superimposed circular movement are shown in dash-dot lines in FIG. 1. In this way, the side 22 of the workpiece 12 can be machined or deburred evenly over the entire surface.
  • FIG. 2 shows the drive-related mounting and mounting of the vertical plate brushes 20 and 21.
  • a first drive motor 37 is flanged approximately in the middle, the output shaft 38 of which plunges into an intermediate shaft 39 and is connected to the latter in a rotationally fixed manner.
  • the vertical intermediate shaft 39 is non-rotatably connected at its lower free end to a first gear 41 which meshes with a larger second gear 42 which is seated on the same plane and which is non-rotatably connected to a receiving spindle 30 for the shaft 28 of the disk brush 21.
  • the intermediate shaft 39 is rotatably connected at its free end and the first gear 41 adjacent to a third toothed wheel 43 which is connected via a toothed belt 44 to a fourth toothed wheel 45 of larger diameter which is mounted on a receiving spindle 29 for the shaft 28 of the Disc brush 20 sits in a rotationally fixed manner.
  • the second gear 42 and the fourth gear 45 are arranged on opposite sides of the intermediate shaft 39 in such a way that their axes and thus the shafts 28 are at the same distance from the axis of the intermediate shaft 39 and the output shaft 38 of the first drive motor 37.
  • the gear wheels 41, 42, 43 and 45 are dimensioned such that the plate brushes 20 and 21 have approximately the same peripheral speeds.
  • the selected gear transmission from the intermediate shaft 39 to the holding spindle 29 on the one hand and the holding spindle 30 on the other hand ensures that the two disk brushes 20, 21 are driven in opposite directions.
  • a holder 48 is rotatably mounted around the intermediate shaft 39, which is also firmly connected to the output shaft 38 in the axial direction, and is held immovably on the shafts 38, 39 in the axial direction.
  • the holder 48 is provided with two receiving bores 51 parallel thereto, in which the receiving spindles 29, 30 for the shafts 28 of the plate brushes 20, 21 are rotatably mounted and axially held.
  • the holder 48 is non-rotatably connected at its uppermost region 53 to a sprocket 56, which is drivingly connected via a chain 54 to a second sprocket 57 which is arranged in the same plane but at a distance and which is non-rotatably mounted on the output shaft 58 of a second drive motor 59 , which is held stationary on the carrier 36 adjacent to the first motor 37.
  • the holder 48 is surrounded in an upper larger diameter cylindrical part 61 by a coolant supply ring 62 which is held in place on the carrier 36 by means of stud bolts 63.
  • the first motor 37 is used to drive the plate brushes 20, 21 in opposite directions about their own axes
  • the second motor 59 is used to achieve a superimposed rotary movement of the pair of plate brushes 20, 21 about the axis of the intermediate shaft 39, which at the same time is that of the holder 48 is.
  • This drive transmission or transmission unit which is described as a planetary head 64, is surrounded by a housing 66 connected to the carrier 36, from whose underside 67 the two holding spindles 29 and 30 for the shafts 28 of the disk brushes 20 and 21 protrude.
  • the identically designed, vertical plate brushes 20, 21 can be clamped with their shank 28 in the respective holding spindle 29, 30 in a rotationally fixed manner and firmly in the axial direction.
  • the lower end of the shaft 28 is fixedly connected to a holding plate 72, on which a plate 74 is firmly held, which holds bristles 75 in the form of a plurality of bundles 76 along an annular ring.
  • connection of the holding plate 72 and the plate 74 takes place by means of cylindrical pins 73 distributed over the outer circumference and by means of a central fastening screw 77 which is screwed into the holding plate 72 from below within the central recess 78 of the annular plate 74 and a recessed ring edge via a profiled disk 79 81 of the annular plate 74 presses against the holding plate 72.
  • the bristles are made of plastic, preferably polyamide, and are covered with abrasive particles, for example corundum, SiC, or the like, over substantially their entire length. Particles occupied.
  • These bristles 75 which are combined in bundles 76, are clamped at one end in the ring-shaped plate 74, for example cast in or glued in, and can be worn down to about a quarter of their length protruding from the underside of the plate 74.
  • the bristles 75 on the plate 74 are supplied with a cooling liquid, for example in the form of a drilling emulsion or oil.
  • a cooling liquid for example in the form of a drilling emulsion or oil.
  • outlet openings 82 of two diametrically opposed bores 83 are provided in the area of the ring edge 81 and are aligned with corresponding bores 84 in the holding plate 72.
  • the ends of these bores 84 open into a transverse bore 85 of the holding plate 72.
  • the transverse bore 85 is provided at both ends with a sealing plug 86 and crosses the end of an axial blind bore 87 in the shaft 28.
  • This blind bore 87 is shown in FIG of the receiving spindle 29 or 30 provided through bore 88, which emerges opposite the mouth of an axial blind bore 89 in the holder 48.
  • This axial blind hole 89 is opposite the receiving spindle 29, 30 in question and opens into a radial blind hole 90 in the holder 48.
  • These two radial holes 90 open into an inner annular groove 91 in the coolant.
  • Feed ring 62 At one point on the circumference of the feed ring 62, a radial connection bore 92 is provided which opens out into the inner annular groove 91 and is provided at the other end with a screw connection for connection to a coolant supply line, not shown.
  • coolant is supplied to a region of the plate brushes 20, 21 which is adjacent to the inner boundary edge of the annular bristle arrangement and is set back with respect to the plane of exit of the bristles from the underside of the plate 74. In this way, a uniform distribution of the coolant over the entire surface of the plate brush area provided with the bristles 75 results during the rotation due to the centrifugal forces.
  • FIG. 4 shows the coolant supply to the horizontal plate brushes 16-19 using one of these plate brushes of the two pairs.
  • the structure of these horizontal plate brushes 16-19 is the same except that their diameter is smaller than that of the vertical plate brushes; therefore the reference numerals also valid for this, as used in FIG. 3, are provided with a dash in FIG. 4.
  • the coolant supply is identical, except for the fact that the receiving spindle 29 for the shaft 27 of the plate brush 16 - 19 is directly surrounded by a corresponding coolant supply ring, which is connected in a corresponding manner to the outlet openings 82 via an inner annular groove and bores .
