Definitions

  • the invention relates to a deep rolling device Deep rolling machine for crankshafts, the scissors construction is executed and in which two pivotable scissor arms one opposite each other Wear a deep rolling head or a support roller head, wherein the support roller head with two paraxial arranged support rollers is provided, whose axes of rotation lie in a common plane, with one Drive device, the closing and Opening movement of the deep rolling device and the Deep rolling force generated.
  • Deep rolling devices of the aforementioned type are known by German Patent DE 197 22 308 C1, a Deep rolling machine for crankshafts disclosed.
  • the design of the deep rolling machine is designed to that when closing each deep rolling machine first the support rollers of the support roller head and then the Deep rolling rollers of the deep rolling roller head to a main or Pleuellagerzapfen be pressed down.
  • the pivoting movement of the support roller and the Festwalzrollenkopfes in the closing sense is with the Danger that there is a collision of the Support roller and the deep rolling roller head with the Crankshaft can come in the area of an oil collar, as the Free spaces between the support roller and the Deep rolling head on the one hand and the two oil bundles of a main or connecting rod journal, on the other hand scarce are measured.
  • the invention is based on the object Deep rolling machine of the type mentioned in the form of that the pivoting movement of the Stauerrollen- and the Deep rolling roller head in the closing sense no Collision with the crankshaft in the area of an oil collar can trigger.
  • this object is achieved in that the support roller head at least one Axial Economicssrolle having in the pivoting direction for closing the the support rollers carrying scissor arm in front of the Support rollers is arranged, whose axis of rotation to the axis of rotation the crankshaft is vertical and lies in one plane, which with the plane of the axes of rotation of the support rollers a acute angle encloses, and whose diameter larger as the width of the support roller head and slightly smaller than the distance of the oil bundles of a major or Connecting rod journal is.
  • a deep rolling machine 1 is provided with a drive device (not shown), the inclusion of a with a crankshaft transport device 2 introduced crankshaft 3 is used.
  • the drive device generates the rotational movement of the Crankshaft 3 about its axis 4 during the deep rolling of the Main 5 and connecting rod pin 6.
  • the axis 4 is thus in the axis of rotation 7 of the drive device.
  • the present embodiment is on the Deep rolling of a main journal 5 of the crankshaft 3 limited, as this explains the Invention subject is sufficient.
  • the main journal 5 is a deep rolling machine. 8 associated with the scissors construction with two scissor arms 9, 10, a scissors fulcrum 11, a Drive device 12, a deep rolling roller head 13 and a support roller head 14 is provided.
  • Scherenbauweise are the deep rolling head 13 and the Support roller head 14 individually in the direction along the Rotary axis 4 not movable. Rather, they are only in certain levels adjustable, which of each location the main journal to be machined 5 or Connecting rod journal along the axis of rotation 4 of the crankshaft. 3 correspond. Such a level is for example in Fig. 3 shown.
  • the drive device 12 has an adjusting cylinder 15 and a power device 16.
  • the adjusting cylinder 15 generates the closing and Opening movement of the above-described scissors of Deep rolling machine 8; the power unit 16 the deep rolling force.
  • the subdivision of the cylinders 15 and 16 generated movements is a particularly narrow construction of the deep rolling device 8 obtained.
  • the deep rolling device 8 is connected via a pivot point 17 a pivotable about an axis 18 angle lever 19th hinged.
  • the angle lever 19 can be pivoted by means of a Piston-cylinder unit 20. By actuating the piston-cylinder unit 20, the deep rolling machine 8 in the and taken from the working position.
  • the deep rolling machine 1 is designed so that when Close the deep rolling device 8, the two first axially parallel arranged support rollers 21, 22 of the Support roller head 14 and then the two fixed rollers 23, 24 of the deep rolling head 13 on the main journal 5 come to the plant.
  • the plane 38 closes - geometrically seen - the Rotary axis 4 of the crankshaft 3 with a, i. the level 38 can oscillate about the axis of rotation 4.
  • FIGS. 3 and 5 clearly show this possibility.
  • the plane falls 38 in the section plane IV - IV, i. the acute angle 37 is 0 ° and the Axial Installationsrolle 27 has from the Plane 34 in which the two axes 32 and 33 lie, a lateral distance s.
  • the two planes 34 and 38 extend to each other parallel.
  • the Axial arrangementrolle 27 may have different shapes to have. In FIG. 3, for example, it has one cylindrical shape. In FIG. 5, the Axial accommodationssrolle 27 a multiple contour, consisting of a cylindrical 39 and a tapered portion 40 composed. Besides, the axial guide roller 27 also be crowned (not shown) configured. at Bearing 5, which has a particularly large width 29a may have, instead of a single Axial Operationssrolle 27 also two axial guide rollers (not shown) be arranged side by side, with the one to the Oil collar 25 and the second applies to the oil collar 26.
  • the diameter 28 of the axial guide roller 27 is larger as the width 29 of the support roller head and slightly smaller than the distance 29a of the oil bundles 25, 26 of the Main Bearing Pin 5.
