Definitions

  • the invention relates to a centrifugal vibratory grinding machine according to the preamble of the claim.
  • centrifugal slide grinding machine is the subject of the earlier application P 32 28 658.9.
  • the liquid added during processing and enriched with abrasion particles flows out through the separation gap. This creates wear, so that after certain times it is necessary to replace the base plate or the container, which is associated with considerable costs.
  • the invention is based on the object of designing the generic centrifugal vibratory grinding machine in a simple manner in terms of production technology in such a way that long service lives are achieved despite a certain amount of wear in the area of the separating gap.
  • the utility value of a centrifugal mass finishing machine of the generic type is increased. If, after a certain period of use, the gap exceeds the predetermined size in such a way that too much liquid passes through it, the gap can be reduced to the required extent in a simple manner by readjustment.
  • the column setting can be done by a Screw adjustment, e.g. B. the bottom plate. Each screw adjustment brings a continuous adjustment. However, spacers can also be provided, namely of different thicknesses.
  • the gap extending in the horizontal plane leads to long service lives of the slide grinding machine combined with not inconsiderable cost savings. If the gap-forming surfaces are formed by overlapping hard metal rings, this leads to a further increase in the service life.
  • the facing carbide ring surfaces are not designed to be exactly flat, they work flat when the centrifugal mass finishing machine is in operation. So that the liquid passing through the gap is not sprayed off somewhere, an apron extends from the underside of the hard metal ring on the container side, adjacent to the outer mouth of the gap. This directs the liquid so that it can be collected completely.
  • One way of maintaining the gap is to provide weight-relieving springs between the support frame and the container. The spring force counteracts the gravity of the container, so that there is always the guarantee of a passage for the liquid between the two hard metal rings.
  • the springs are arranged approximately at the height of the gap and are penetrated by adjusting pins which are supported on one end on an annular flange of the support frame and on the other end on an annular flange of the container.
  • the adjustment pins designed as screws then allow the gap to be reduced by simply adjusting the nuts.
  • the adjustment pin is supported with the interposition of a second spring against the underside of the support ring flange. With regard to this second spring, it is a spring of less dimension, so that the preset gap is always maintained. This results in an aquaplaning effect or a floating arrangement of the container if a larger throughput of liquid through the gap should occur in the short term. This also compensates for unevenness in the rings.
  • the centrifugal vibratory grinding machine has a support frame 1 with two side walls 2, 3 lying parallel to one another. An inclined bottom wall 4 extends between these and is supported in its upper region by a transverse wall 5. The lower end of the bottom wall extends up to a further transverse wall 6. This projects beyond the bottom wall 4 and continues at its upper end into a horizontally angled wall section 7, which in turn has an angled, vertically oriented web 8.
  • the side walls 2, 3 carry a rocker 10 in their upper region by means of trunnions 13.
  • the rocker 10 is equipped with a drive motor 11 at its end above the transverse wall 6.
  • the other, larger area end of the rocker 10 sits in one upward flange 12 from which the aforementioned journals 13 extend.
  • the horizontal working position of the rocker 10 is limited by the fact that on the underside of the rocker, opposite the drive motor 11, stops 14 made of flexible material are provided, which are supported on the wall section 7 forming a counterstop surface, see FIG. 2 Rocker 10 still 15 stops provided. The same interact with the web 8 in the tilted position of the rocker.
  • the slide grinding container 17 which is made of polyurethane, is circular on the inside, while it forms a pentagon on the outside.
  • the container 17 On the bottom side, the container 17 has an outwardly projecting annular flange 19. This is provided with sleeves 20 arranged in the same circumferential distribution.
  • these sleeves 20 pass through adjustment pins 21 designed as screws.
  • the screw head 26 of the adjusting pin 21 is supported on the underside of the ring flange 25.
  • the bracing takes place against the force of springs 9 designed as compression springs, which are arranged on the adjusting pin 21 and extend between the ring 23 and the ring flange 25. As a result, the container 17 is carried.
  • the ring 23, which is supported on the underside of the ring flange 19, is the carrier of a hard metal ring 28.
  • the connection of the two rings 23, 28 takes place by welding.
  • the alignment of the rings 23, 28 is such that their undersides are cursed with one another.
  • annular skirt 29 extends in the area of the outer edge in such a way that it overlaps into the flange 12, leaving an outer ring zone Z free.
  • a hard metal ring 30 extends underneath it. Like the hard metal ring 28, this is aligned horizontally and fastened to the upper edge of a rotating disk forming the bottom 31 of the container 17.
  • the upper side of the bottom 31 has a lining 32 made of polyurethane.
  • a horizontally running gap S extends between the hard metal ring 30 of the base 31 and the hard metal ring 28 on the container side. This gap is maintained by the force of the compression springs 9, which are at approximately the same height. The gap size can be changed by turning the nuts 27.
  • the flank 28 ′ of the hard metal ring 28 facing the container axis tapers downwards towards the center of the container and runs out at the level of the inner edge 30 1 of the hard metal ring 30 on the bottom.
  • the inner flank 28 ' continues into an upwardly widening wall section 33 of the container 17. This merges via a step 34 into a slightly widening wall section 35 which ends in a cylindrically oriented wall section 36.
  • projections 37 are provided which extend approximately beyond the fill level and project inward from the container. The same are designed as strips lying in the height direction of the container 17, which are made of the same material
  • Container walls are molded in the same angular distribution. The latter have a rear surface that faces the direction of rotation and enters the inner surface.
  • the drive motor 11 drives the floor 31 via a toothed belt drive, not shown.
  • the mixture of processing bodies, workpieces W and treatment liquid is pressed by the rotating base 31 against the inner wall of the container 17 and is conveyed upwards. From there it slides back to the center of the rotating floor 31. As a result of the rotation of the base 31, an annular bead is produced in the container 17.
  • Any treatment liquid enriched with abrasion located in the bottom area can now enforce the gap S between the two hard metal rings 28, 30 due to centrifugal force. From there, the liquid splashes against the inner wall of the apron 29 and then flows to the bottom wall 4.
  • the gap S between the two hard metal rings 28, 30 has become larger due to possible wear, the gap can be brought back to the appropriate dimension by turning the nuts 37.
  • the adjustment pin 21 ' is longer. His screw head 26 1 does not support un indirectly from the underside of the ring flange 25. It is supported on this by a second spring 40, which is designed as a compression spring and is arranged between the screw head 26 1 and the underside of the ring flange 25.
  • the spring is weaker than the spring 9 Tungsten carbide ring 30 held.
  • An enlargement of the gap S is produced in that the nut 27 is rotated towards the end of the adjusting pin 21 '. Should a larger amount of liquid suddenly enter the gap S in this embodiment, this leads to a floating of the hard metal ring 28 or the container 17 against the force of the springs 40.
  • a buffer made of flexible material could also be provided be.
