Definitions

  • the invention relates to a deep rolling machine or smooth rolling machine for rolling at least the surfaces eccentrically arranged on a workpiece, with means for receiving and rotating the workpiece and with at least one movable rolling device, at least comprising a tool holder with at least one rolling element and a tool holder with at least one a support element, with each movable rolling device being moved by the workpiece.
  • Machines of the type described above have become known, for example, from DE-OS 33 33 603.
  • the adaptation of the spatial position of the rolling devices, for example on crankshafts each with a different stroke, is associated with a high mechanical outlay and in terms of control technology because of the necessary calculation of angular positions of the complex mechanical system also connected with great effort.
  • a weight-neutral position with regard to the swivel arm carrying the deep rolling devices is only possible with a very specific type of crankshaft. With any other type of crankshaft, additional inertia forces are undesirably applied to the crankshaft to be rolled by the swivel arm.
  • the adaptation to different strokes is also very limited due to the limited pivoting possibility of the swivel arm carrying the rolling devices.
  • the invention is therefore based on the object of proposing a machine of the type described in the introduction, with which it is possible with simple means, in a wide range Areas of adaptation to different workpieces with at least different eccentricities, such as crankshafts with different strokes, as well as to different angles of rotation of the surfaces to be machined.

  • the movable rolling devices are arranged in the assigned radial plane in two independent coordinate directions in a linearly variable position. These coordinate directions preferably form the axes of a Cartesian coordinate system. This makes it easy to determine and retract each point on the radial plane.
  • a further embodiment of the invention provides that at least one rolling device is arranged to be movable in a coordinate direction perpendicular to the radial plane mentioned.
  • the machine can also be adapted to changing distances between the surfaces to be machined in the axial direction using the simplest of means. The adaptability This extends the machine to different workpieces.
  • At least one further rolling device is provided, at least this rolling device being arranged in a positionally variable manner in a radial plane of the crankshaft in such a coordinate direction in which the position of the rolling tools can be adapted to the pin diameter of a workpiece area to be machined is.
  • An embodiment of the invention provides that the movable rolling device is suspended on a swivel arm about an axis parallel to the workpiece axis, which in turn is suspended in the machine so as to be pivotable about an axis parallel to said axis and can be locked in at least one pivot position.
  • the axis mentioned changes position in a radial plane of the workpiece is arranged, whereby the ability to move is expanded in a simple manner.

  • the said axis can be removed from the support device at least in one plane transverse to the workpiece axis, e.g. be moved to the crankshaft axis, so that practically an adaptation to any stroke differences and stroke sizes and any angular position positioning is easily possible.
  • this makes it possible to move one or more complete devices completely out of the work area, so that adaptation to a changing number of surface areas to be processed is also possible in this way.
  • a further embodiment of the invention provides that the support device comprises a slide which can be moved transversely to the crankshaft axis and which is arranged in a slide carrier with a slide guide, an adjustment drive which is effective between the slide and the slide carrier being provided.
  • the slide carrier is guided in a vertically movable manner on the crossbar via vertical guides and is connected to an adjustment drive supported on the crossbar, while a further adjustment drive between slide and slide carrier is effective.
  • Another embodiment of the invention provides that for locking the swivel arm in a swivel position on the movable carriage, two fluid cylinders acting counter to the swivel arm are provided, which swivel the swivel arm into the desired position and hold it there.
  • two fluid cylinders acting counter to the swivel arm are provided, which swivel the swivel arm into the desired position and hold it there.
  • a supplementary embodiment of the invention provides that of the two fluid cylinders, a cylinder with its first end position has a first pivot position and with its second end position determines a second swivel position of the swivel arm, the second cylinder being operated with less force than the first cylinder, at least for fixing the first swivel position.
  • This is certainly the simplest possible way to move in and fix two desired positions.
  • a pivotally mounted lever is provided on the pivot arm, which lever can be actuated by a fluid cylinder also arranged on the pivot arm, the free end of which can be pressed against the associated rolling device in order to bring it into a specific pivot position.

  • At least one rolling cement and / or support element is arranged on the tool carrier in a variable position.
  • the fact that at least one rolling element and / or support element on the tool carrier is arranged such that it can be changed in position can simplify the construction of the device, at least in certain applications, and this position variability can at the same time facilitate the introduction of a workpiece into the device. Due to the change in position mentioned, it is not only possible if necessary. bring different elements to the place of use, but it is also possible to remove the corresponding element from the place of use and return it to the place of use after the insertion of a piece of value.
  • each rolling element and each support element is an element of a roller head.
  • Roller heads with rolling elements are already known and have proven themselves.

  • At least one tool holder carries at least one roller head.
  • this enables the machine to be equipped differently to suit specific production conditions, and on the other hand it is at least partially possible to use existing roller heads.
  • roller heads are arranged in at least two positions, of which at least one position is the working position.
  • a supplementary alternative of the invention provides that the roller heads are arranged on a guide for changing the position. This is a space-saving and simple construction for changing the position. The roller elements and / or support elements are then changed in their position at the same time with the roller heads.
  • an actuating device is provided for carrying out the change in position, it then further being proposed that at least one fluid-operated piston-cylinder unit is provided as the actuating device.
  • Actuating devices specially designed to carry out the change in position, coordinated and appropriately designed and arranged, are easy to implement and facilitate the change in position.
  • At least one more position is provided or predeterminable for the tool holder than it carries roller heads.
  • the movable rolling device consists essentially of two scissors-like arms which are kinematically connected to a force actuating means for generating the rolling force.
  • a force actuating means for generating the rolling force Such a configuration allows high rolling forces to be exerted on the workpiece in a small installation space, these rolling forces canceling each other out on the workpiece itself, so that one of the rolling forces resulting additional undesirable radial loading of the workpiece is prevented.
  • the scissor-like connection of the arms does not have to mean that a pivot point is present approximately in the middle of the arms. It is quite possible to place the articulation point on one end of the arms, for example, and thus connect the ends of the arms to one another.
