Definitions

  • the invention relates to a device for roughening the cylinder bores of cylinder crankcases according to the preamble of claim 1.
  • At least one cylinder crankcase in the direction of the row of cylinder bores can be introduced on a workpiece carrier plate of a device housing (arrow G).
  • a vertical base plate is assigned, which runs parallel to the row of cylinder bores of the introduced cylinder crankcase.
  • On the base plate at least two vertically adjustable (arrows B and C) shaft housing are arranged to receive the hollow shafts with rotatable nozzle blocks (arrows E and F).
  • the nozzle blocks are in a vertical adjustment (arrows E and F) in non-adjacent cylinder bores of the cylinder crankcase and out, with a connected to the terminal supports high-pressure liquid source is switched on and off.
  • the base plate or the workpiece carrier plate is adjustable for further processing of cylinder bores of the cylinder crankcase by a pitch of the cylinder bores in the row (arrow D or arrow G).
  • Another embodiment of the device is characterized in that on a workpiece carrier plate of a device housing at least two juxtaposed cylinder crankcase with parallel rows of cylinder bores in the direction of the rows of cylinder bores can be introduced (arrow H).
  • the device housing is in the range of the introduced cylinder crankcase associated with a vertical base plate which is perpendicular to the rows of cylinder bores of the introduced cylinder crankcase.
  • On the base plate at least two vertically adjustable (arrows B and C) shaft housing are spaced from the rows of cylinder crankcases of two adjacent cylinder housing, the hollow shafts with rotatable nozzle blocks (arrows E and F) record.
  • the nozzle blocks in the same cylinder bores of two adjacent cylinder crankcases are in and out, with a connected to upper terminal supports high-pressure liquid source is switched on and off.
  • the base plate or the workpiece carrier plate is adjustable for further processing of cylinder bores of adjacent cylinder crankcase perpendicular to the base plate by a pitch of the cylinder bores in the row (arrow K or arrow H).
  • these two embodiments of the device can also unite to form a device which is characterized in that the two shaft housing on the base plate at a distance A are mutually variable.
  • the base plate is optionally horizontally displaceable in its plane (arrow D) or perpendicular to its plane adjustable (arrow K).
  • the workpiece carrier plate can be adjusted either parallel (arrow G) or vertically (arrow H) to the base plate.
  • the device is designed by selecting the adjustment devices for processing behind one of the ( Fig. 1 ) or parallel juxtaposed cylinder crankcase suitable and usable.
  • the nozzle blocks and the hollow shafts are smaller in outer diameter than the smallest inner diameter of the cylinder bores to be machined.
  • the nozzle blocks with the hollow shafts protrude at the bottom of the shaft housing to the maximum depth of the cylinder bores.
  • the drives for the adjustments (arrows B and C) of the shaft housings are fixed to the base plate and the rotary motion drives (arrows E and F) are attached to the shaft housings.
  • the adjusting movements (arrows D and K) of the base plate and the adjusting movements (arrows G and H) of the workpiece carrier plate are adapted to the pitch of the cylinder bores in the row of the cylinder crankcase and tuned.
  • Fig. 1 can be seen, at least one cylinder crankcase 10 is applied to the workpiece carrier plate 30 with a series of arranged in a predetermined pitch cylinder bores 11. With more than one cylinder crankcase 10 on the workpiece carrier plate 30, the cylinder bores 11 form a continuous row.
  • the workpiece carrier plate 30 may have guide or Fixierfactn 12, in the guide or fixing bolts 31 of the workpiece carrier plate 30 engage.
  • the cylinder crankcase 10 are therefore clearly and immovably fixed in the position on the workpiece carrier plate 30.
  • the workpiece carrier plate 30 can be introduced in the direction of the row of cylinder bores 11 in the device housing.
  • the workpiece carrier plate 30 In the inserted position of the workpiece carrier plate 30 is associated with a vertical base plate 20 which is aligned with its plane parallel to the row of cylinder bores 11 of the integrated cylinder crankcase 10.
  • On the base plate 20 are at least two shaft housing 21 and 25 vertically adjustable, as the arrows B and C show. In this case, the distance A of the shaft housing 21 and 25 is adjusted so that the central longitudinal axes of the shaft housing 21 and 25 are aligned with the central longitudinal axes of non-adjacent cylinder bores 11.
  • a cylinder crankcase 10 with four cylinder bores 11 this is the first and third cylinder bores 11, so that the cylinder crankcase 10 can be machined in two processing steps.
  • the shaft housings 21 and 25 are aligned with the first and fourth cylinder bores 11.
  • n / 2 operations are required when the workpiece carrier plate 30 carries only one cylinder crankcase 10.
  • the device is particularly simple when the workpiece carrier plate 30 carries only a cylinder crankcase 10.
  • hollow shafts 22 and 26 with rotatably mounted and drivable nozzle blocks 23 and 27 are arranged.
  • the nozzle rods 23 and 27 with the hollow shafts 22 and 26 are smaller in outer diameter than the smallest inner diameter of the cylinder bores 11, so that the device for all cylinder crankcases 10 is usable. In this case, project the hollow shafts 22 and 26 with the nozzle blocks 23 and 27 at least by the maximum depth of the cylinder bores 11 on the lower side of the shaft housing 21 and 25, so that the device can also edit the cylinder bores 11 with the greater depth.
  • Fig. 2 shows, on the workpiece carrier plate 30 and at least two cylinder crankcases 10 are applied side by side, the rows of cylinder bores 11 are parallel and the individual cylinder bores 11 are aligned parallel to the base plate 20 when the workpiece carrier plate 30 is perpendicular to the vertical base plate 20 introduced into the device housing becomes (arrow H).
  • the two shaft housings 21 and 25 are set to a distance from each other, which corresponds to the distance of the two rows of cylinder bores 11 of the adjacent, applied to the workpiece carrier plate 30 adjacent cylinder crankcase 10. The roughening process takes place in the same way.
  • the nozzle blocks 23 and 27 are in the vertical adjustment of the shaft housing 21 and 25 inserted into the aligned cylinder bores 11 and led out again, wherein the connected to the terminal supports 24 and 28 liquid high-pressure plate is turned on and off.
  • the base plate 20 makes an adjusting movement (arrow K) in the direction of the cylinder crankcases 10 on the workpiece carrier plate 10 or the workpiece carrier plate 30 an adjustment (arrow H) in the direction of base plate 20.
  • This adjustment corresponds to the pitch of the cylinder bores 11 of the workpiece carrier plate 30 applied cylinder crankcase 10th
  • the workpiece carrier plate 30 has two drives in order to make the insertion direction thereof parallel or perpendicular to the base plate 20 (arrow G, FIG. Fig. 1 or arrow H, Fig. 2 ).
  • the base plate 20 can be assigned two drives, wherein the base plate 10 either horizontally adjusted in its plane (arrow D, Fig. 1 ) or with its plane perpendicular in the direction of the workpiece carrier plate 30 is adjustable (arrow K, Fig. 2 ).
  • the device can then be used for processing one after the other or in parallel on the workpiece carrier plate 30 applied cylinder crankcase 10. In this case, select drives of the device for the desired sequence of movements and apply the cylinder crankcase 10 in the assigned position on the workpiece carrier plate 30.
