Definitions

  • the invention relates to an arrangement for protecting cylinder walls of engine blocks according to the preamble of claim 1.
  • engine blocks are increasingly used in the manufacture of internal combustion engines made of light metal, whose cylinder walls by means of a thermal coating device be provided with an iron-containing running layer.
  • rotating plasmatrons are preferably used in this running layer.
  • the cylinder bores that are not in the active coating process be protected from pollution.
  • This pollution can, for example, from Coating particles originate that are not on the wall of the active coating process existing cylinder stick.
  • gas flow also entrains dust particles that are unwanted could deposit the cylinder walls and undesirable particle inclusions in the applied or the layer to be subsequently applied.
  • an inflatable "mask” which consists of a dimensionally stable, cylindrical Base part and a tubular inflatable bag attached to the top of the base part is attached.
  • the mask is used to protect parts of an engine block, especially of the crankshaft housing during the coating of cylinder bores. For this purpose, the mask is brought up to the cylinder to be coated from below. While During the coating process of cylinder bores, air is removed from the respective mask Aspirated cylinder.
  • the object of the invention is now to have a simple structure and use To create an arrangement by means of which is not in the active coating process cylinder walls located on engine blocks are protected against contamination can be.
  • FIG. 1 shows an arrangement 1 for protecting cylinder walls of engine blocks 2 of internal combustion engines.
  • an engine block 2 of a V-10 internal combustion engine In the present case is an engine block 2 of a V-10 internal combustion engine.
  • Engine block 2 The pivotally received in a frame 17 Engine block 2 is aligned in such a way that the cylinders 3 of those to be coated Cylinder bank 4 run vertically while the cylinders 5 follow coating or already previously coated other cylinder bank 6, conditionally run horizontally through a 90 ° angle between the two rows of cylinders 4, 6. If one speaks of cylinders in each case, this is in most cases to understand the actual cylinder bore.
  • plasma spraying devices with rotating burner heads can be provided, as are known from EP 0 601 968.
  • the arrangement 1 comprises a total of one with the number of cylinders 3, 5 of the engine block 2 corresponding number of shaped bodies 10, a total of ten in number, which on both sides of the frame 17 in two groups 9, 11, each with five shaped bodies 8, 10 are arranged.
  • the molded bodies 8, 10 are via schematically indicated lines 16 connected to an overpressure source, not shown, with only those to of a group 11 leading lines 16 are shown.
  • Each group 11 has a support frame 13, 14, which is horizontally displaceable, so that the molded body 8, 10 can be retracted or extended into the cylinders 3, 5.
  • FIG. 2 shows a shaped body 10 in an enlarged representation in cross section.
  • the molded body 10 has a dimensionally stable inner sleeve 18, which is of an elastic Envelope 19 is enclosed.
  • the sleeve 19 is preferably made of silicone, because silicone is elastic on the one hand and withstands high temperatures on the other. How indicated by arrows, can in the space 20 between the inner sleeve 18 and Envelope 19 pressurized air are introduced, so that the envelope 19 radially is pushed outwards. By supplying air under pressure the outer diameter of the casing 19 increases.
  • the inflatable molded body 10 in the cylinder 5 introduced and inflated therein.
  • the molded bodies 10 are designed such that they are slightly longer than the corresponding cylinder 5, so that they are axially on the latter tower over both sides.
  • the edge regions of the Cylinder 5 protected because the outside diameter of an inflated envelope outside the cylinder bore is slightly larger than the cylinder diameter and a kind Protective bead forms.
  • the molded bodies 8, 10 designed according to the invention are suitable both for different bore diameters as well as different bore lengths. In this respect, it does not matter whether the molded bodies 8, 10 are used to protect them Cylinders provided with a sliding layer or from uncoated cylinders.
  • the arrangement shown is particularly suitable for V and boxer engines, since the Coating engine blocks of those engines are those cylinders that are the same opposite cylinders in the active coating process with respect to any pollution is exposed.
