Definitions

  • the invention relates to a device for deep rolling or smooth rolling of crankshafts with at least one movable rolling device, each of which contains a tool holder with at least one rolling element and a tool holder with at least one supporting element, and with at least one further rolling device, the rolling devices being moved from one to one Carriage attachable stand to be carried.
  • FIG. 1 Facilities of the type described above are known and have proven themselves in practice. They can be constructed so that they can be placed on the bed slides of a lathe or a lathe-like machine as so-called attachment devices.
  • the lathe can then accommodate, clamp and drive a workpiece to be rolled, preferably a crankshaft to be rolled, on the one hand in a chuck and on the other hand in the center point of the quill.
  • the required rolling device is then manually applied with its tools to the bearing point to be rolled and the necessary rolling pressure is applied and the lathe is driven.
  • a rolling device for connecting rod bearing journals to be rolled is carried along by the connecting rod bearing because of its oscillating suspension. In the rest position, it is kept in balance by spring elements.
  • the invention is therefore based on the object of proposing a device of the type described at the outset with which it is possible to at least match the rolling devices with the rolling tools to different crankshaft types with regard to the crankshaft stroke adapt.
  • a device of the type described in the introduction in that the movable rolling devices are arranged in a positionally variable manner in relation to the other rolling devices in a radial plane of a crankshaft, a slide or a slide-like element being provided at least for the movable rolling devices Sled carrier is arranged, which in turn is arranged on a support element which is arranged on the stand.
  • Such an arrangement of the rolling devices enables adaptation to different stroke sizes of the bearing points of a crankshaft by changing the position of the movable rolling devices in said radial plane. This makes it possible for the first time to adjust the stroke of such attachment devices which have at least two rolling devices.
  • Sled constructions are particularly well-proven for carrying out linear changes in position and are safely mastered in production and maintenance. Such a structure also allows the desired mobility and is easy to manufacture.
  • the constructive structure uses proven construction elements, which on the one hand are mastered safely and on the other hand guarantee high functional reliability.
  • each movable rolling device is arranged in the associated radial plane in at least two independent coordinate directions in a linearly variable position, the support element being guided vertically displaceably and adjustably on the stand.
  • At least one rolling device is arranged to be movable in a coordinate direction perpendicular to the radial plane mentioned. This enables problem-free adaptation to different distances between the surfaces to be machined in the axial direction.
  • a further embodiment of the invention provides that at least the movable rolling devices in a radial plane of a crankshaft are arranged so as to be variable in position regardless of the movement of the movable carriage. This further simplifies the construction and, at the same time, it is possible to bring the rolling devices into and out of engagement without changing the relative position of the rolling devices.
  • movable rolling devices are arranged such that they can be changed in position in relation to the other rolling devices in the axial direction of the crankshaft. This in turn simplifies the construction and, on the other hand, it becomes possible to keep the entire device in the axial direction in the same position, while the movable rolling device is used to adapt to different positions of the workpiece surfaces to be machined in the axial direction.
  • each movable rolling device is pivotally suspended about a pivot axis parallel to the axis of a crankshaft to be rolled on a pivot arm which in turn is pivotally suspended on the device about an axis parallel to said pivot axis.
  • the stand and the support element are designed as round guides, the support element being guided in the stand in a non-rotatable but movable manner. This is a particularly simple constructive design to achieve the desired flexibility and adjustability.
  • the axis parallel to the mentioned pivot axis continues as a circular guide and forms a slide which is slidably guided in a corresponding hole in the other slide.
  • a circular guide considerably simplifies construction and production.
  • one of the two fluid cylinders determines a first pivot position of a cylinder with its first end position and a second pivot position of the swivel arm with its second end position, the second cylinder with less force than the first at least for fixing the first pivot position Cylinder is operated. This is the easiest way imaginable to move in and fix two desired position positions.
  • a supplementary embodiment of the invention provides that 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.
  • a balancing of the rolling device for example by means of springs, can be avoided, and the rolling device becomes simple and yet reliable in the correct pivot position held for repositioning. It is important here, however, and it should be pointed out that the pivot point of the deep rolling device lies in front of the pivot axis of the deep rolling device on the swivel arm, so that a clear direction of movement or pivoting direction of the deep rolling device is fixed.
  • Another embodiment of the invention in turn provides that the entire device is arranged on a bed slide of a machine for receiving and driving a crankshaft and is arranged to be displaceable together with the bed slide on the machine bed.
  • the entire device is arranged on a bed slide of a machine for receiving and driving a crankshaft and is arranged to be displaceable together with the bed slide on the machine bed.

  • the fact that the respective rolling device is movable and is connected to only one power actuating device ensures that only the rolling force occurs as a transverse force on the workpiece and is canceled out there. Additional lateral forces that could stress the workpiece and that result from the power actuation device are largely avoided.
  • the presence of at least one further rolling element and / or support element, which can change position in the manner described, makes a tool exchange unnecessary in the case of corresponding workpieces, and time is thereby saved in production.
  • greater flexibility of the device is achieved because, within a certain frame, the device according to the invention can react to the design of the workpiece with a corresponding change in position of the rolling elements and / or the support elements. It it is also possible to use fewer rolling devices in a single device and to move them to the point to be rolled on the workpiece and to make a selection by changing the position of the support elements and / or the rolling elements, so that a at the respective place of work suitable tool is used.
  • At least one rolling element 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 is arranged in a positionally variable manner on the tool carrier can simplify the construction of the device, at least in certain applications, and this positional 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. to bring different elements to the place of use, but it is also possible to remove corresponding elements from the place of use and return them to the place of use after inserting a workpiece into the machine.
  • 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.
  • the use of such roller heads in a device of the type according to the invention further increases the economy of such a device, e.g. in that the spare parts inventory can be reduced and can essentially be limited to the 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 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 an additional, undesirable radial load on the workpiece resulting from the rolling force is prevented.
