- the invention is therefore based on the object of proposing a machine of the type described at the outset, with which it is possible with simple means to adapt to wide workpieces with at least different eccentricities, such as e.g. on crankshafts with different strokes, as well as at different angles of rotation of the surfaces to be machined. This adjustment should also be able to take place automatically if necessary.
- this object is achieved in a machine of the type described in the introduction in that the movable rolling devices are arranged in a linearly variable position in a radial plane of the workpiece, the swivel axis for the swivel arm being arranged in a support device which in turn is supported by a crossbar supported on the machine stand is and is connected to adjustment drives that allow an adjustment of the position of this axis at least in one plane transverse to the crankshaft axis with at least one horizontal and / or vertical component.
- This is a simple constructive structure in order to achieve the desired mobility with the simplest of means.
- the linear position variability is easy to control in terms of size and direction and is easy to implement in terms of device technology.
- said axis can be moved by the support device at least in one plane transverse to the workpiece axis, for example 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 use one or to move several complete devices completely out of the work area, so that an adaptation to a changing number of surface areas to be processed is possible in this way.
- 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. This increases the machine's adaptability 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.

- 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.
- the use of such roller heads in a device of the type according to the invention further increases the economic viability of a device of the type according to the invention in that the supply of spare parts can be reduced and can essentially be limited to the roller heads. Furthermore allows the use of such roller heads a simpler construction of the device.
- a supplementary embodiment of the invention provides that an independent roller head is provided for each rolling element and / or for each supporting element or supporting element pair or rolling element pair.
- the structure of the roller heads can be standardized, so that the same roller heads can always be used in machines with a different number of rolling elements, so that the different number of rolling elements is achieved simply by varying the roller heads.
- each roller head is arranged in a variable position on the associated tool carrier. This is an easy way to bring the respective roller head into a desired position.
- At least one tool holder is provided with a tool holder that can be changed in position in at least two predetermined or predefinable positions, with at least one rolling element or support element that extends over the tool holder in the positions mentioned can be brought, wherein at least one rolling element in the working position and / or at least one associated support means can be kinematically connected or connected to a force actuating means.

- different equipment of the machine can be achieved in adaptation to certain 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.

- 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 makes it possible to exert high rolling forces 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 hinge point is present approximately in the middle of the arms. It is also possible to place the joint point at one end of the arms, for example, and thus to connect the ends of the arms to one another.
- a rolling device is provided with at least one rolling element and / or a support element, which is each arranged in a fixed position with respect to the associated tool carrier.
- the rolling elements and / or support elements must then be arranged in a fixed position in relation to the associated tool carrier.
- the rotary drive of the workpiece is controlled by the angle of rotation, the angle of rotation position of the workpiece and the position of at least one movable rolling device in the radial plane being mutually dependent.
- a machine of the type according to the invention is usually equipped with several rolling devices.
- the rolling devices can also be of different types.
- the workpiece is driven centrally via a separate workpiece drive, if necessary. is controlled by the angle of rotation.
- rolling devices designed according to the invention can be movable along a workpiece axis in a machine of the type according to the invention, so that the rolling devices can be moved into the desired and pre-programmable working positions via appropriate drive and control means, for example via programmable NC controls can be driven.
- the program can not only position the rolling devices themselves, but also select the tools to be positioned.
- a deep rolling device 1 or 1 ' is pivotally suspended on a swivel arm 51 in the plane of the drawing by means of the articulated axis 60.
- the swivel arm 51 which consists of two parallel legs, also carries a lever 56, which is also pivotably arranged in the plane of the drawing, and is operatively connected to a fluid cylinder 57 which is also fastened to the swivel arm 51.
- the free end 58 of the lever 56 can be pressed via the fluid cylinder 57 in the manner shown in FIG. 4 against the deep-rolling device 1 or 1 ", whereby the said deep-rolling device is caused to pivot in the plane of the drawing about the pivot axis 60.
- the said deep rolling device is to be pivoted into the position shown in FIG. 4, which is used for repositioning to another type of crankshaft and for placing the devices on it rolling bearings is needed.
- the deep rolling devices 1 and 1 ' are arranged such that their center of gravity S is in the manner shown in Figure 4 in front of the pivot axis 60 so that the weight of the respective deep rolling device presses it against the free end 58 of the lever 56.
- the free end 58 of the lever 56 is pivoted away so that the mobility of the deep rolling device 1 or 1 'concerned is not hindered.
- the swivel arm 51 in turn is pivotally suspended on a carriage 47 via an axis 40 arranged parallel to the swivel axis 60.
- the slide 47 is guided in a slide carrier 48 so as to be displaceable transversely to the crankshaft axis 46.
- Carriage 48 and carriage 47 essentially form the support device 41 for the swivel arm 51 and for the deep-rolling device 1 or 1 'attached to it.
- the slide carrier 48 has two vertical guides 50, which are designed as circular guides and are moved vertically in a traverse 43 in the direction of the arrow 67.
- the cylinder body of a fluid cylinder, the piston rod 61 of which is attached to the slide carrier 48, is fastened to the cross member 43, this cylinder being designed as a fluid cylinder and forming the adjusting drive 44.
- the slide carrier 48 can be moved and positioned vertically.
- the adjustment drive 44 does not have to be designed as a fluid cylinder, however. It can just as well be an electromotive adjustment drive act, the carriage 48 then being moved vertically by the electric motor, for example via a ball screw.
- the electric motor can have such a design that the vertical path covered by means of the ball screw can be measured exactly. Vertical positioning of the carrying device 41 is thus possible in the simplest way.
- the cross member 43 supporting the entire support device is in turn supported on the machine stand 42 and can be arranged there in the direction of the arrow 59 so as to be movable and attachable. In this way, side positioning can also be made possible.
- the adjustment drive 45 for the adjustment or displacement of the slide 47 can also be designed here, for example, as a fluid cylinder, the cylinder body then in turn being supported on a cantilever 62 of the slide carrier 48 and being fastened there, while the piston rod 63 is fastened on the slide 47.
- An inward and outward movement of the piston rod 63 brings about a corresponding displacement of the slide 47 in the direction of the arrow 66.
- the adjustment drive 45 can again be effected by an elector motor, as already described.
- the slide guide 49 for the slide 47 is designed in the exemplary embodiment as a dovetail guide. It can save space also be designed pivoted by 90 °. However, the guidance of the carriage 47 in the carriage carrier 48 is not restricted to a dovetail guide.
- fluid cylinders 52 and 53 are attached to the slide 47.
- the piston rods 64 and 65 of the fluid cylinders mentioned can each be brought into contact with the swivel arm 51, acting in the opposite direction.
- the fluid cylinder 53 is operated with greater force than the other fluid cylinder and the piston rod 65 is extended to its stop. As a result, the swivel arm 51 has reached the first swivel position 54.
- the piston rod 64 of the fluid cylinder 52 is moved against the pivot arm 51, but with less force than the force of the piston rod 65, so that in the first pivot position 54 the pivot arm 51 is clamped between the piston rods 65 and 64 and thus locked is.
- the deep rolling devices can be placed on the bearings to be rolled.
- the lever 56 can also be swiveled so that the free end 58 no longer bears against the deep-rolling device 1 or 1 'and, because of the position of the center of gravity S in the plane of the drawing, it folds downward. In this way, an automatic adaptation to changing number of trunnions can be achieved while maintaining the basic positioning of the devices.
- the deep-rolling device 1 consists essentially of two arms 6 and 7. These arms 6 and 7 are connected to one another in a known manner via the tabs 23 and the hinge pin 24 in a scissor-like manner. At the opposite rear ends 8 and 9, a piston-cylinder unit 10 is also arranged in a known manner, which moves the arms 6 and 7 like pliers or scissors. At the end 11 opposite the end 8 and at the end 12 opposite the end 9, the roller head required in each case is arranged on an arm 6 or 7 in the prior art. In the deep rolling device according to the invention, however, the hinge pins 25 and 26 are provided there, which carry the fork-shaped levers 19 and 20 in an articulated manner. The levers 19 and 20 can thus swing freely about their hinge pins 25 and 26, as indicated by the arrows 27 and 26 '.
- a piston-cylinder unit 21 is connected via a piston rod to the lever 19 via a joint 28, while the cylinder of the piston-cylinder unit 21 is supported on the lever 6.
- the lever 19 In the switching position shown in FIG. 1, the lever 19 is in the angular position 15.
- known deep-rolling tools 13 and 13 ' are arranged. In the angular position 15 of the lever 19, the deep rolling roller head 13 is in the working position.
- a support roller head 14 Arranged opposite the deep rolling roller head 13, in a manner known per se, is a support roller head 14 which is arranged on the lever 20.
- the angular position 17 of the lever 20 holds the support roller head 14 in the working position, so that the transition radii 2 on the main bearing 3 can be rolled.
- the levers 6 and 7 are moved via the piston-cylinder unit 10 in a manner known per se and thus the deep rolling roller head 13 and the support roller head 14 are brought into contact with the corresponding bearing points of the crankshaft 5.
- the connecting rod bearing 4 can be rolled in the region of the fillets 2.
- only a corresponding device has to be arranged.
- the multiple arrangement of such devices is known from the literature on the prior art which has already been cited. A detailed description of this multiple arrangement can therefore be dispensed with here.
- crankshaft 5 For the machining of the crankshaft 5, this is, as shown in FIG. 2, received between centers and driven centrally.
- crankshaft 5 now arrives as the next workpiece with, for example, modified fillet radii
- the piston-cylinder unit 21 is actuated so that its piston rod retracts.
- the lever 19 is moved from the angular position 15 to the angular position 16 hazards.
- the deep rolling roller head 13 'comes into the working position and the crankshaft 5 with the changed radii can be rolled.
- the pivoting movement in the direction of arrow 27 of the lever 19 is of course in no way limited to the two switching positions described in the exemplary embodiment. More than two switching positions can also be provided. Likewise, more than two deep rolling roller heads can be used. But depending on the application of the deep rolling device 1, it may also make sense to provide only a single deep rolling roller head 13, for example if the now possible swiveling movement via the lever 19 is only or preferably to serve to simplify the tool change for the tool 13 or in the case a break of the deep rolling rollers to simplify the changing of the deep rolling rollers by better accessibility. However, the insertion of the workpiece can also be simplified by such a pivoting movement.
- the support roller head 14 can also be pivoted in the direction of the arrow 26 ', for example by means of the handle 22 from the angular position 17, which represents the working position, into the angular position 18.
- the locking bolt 29 is removed so that the lever 20 can now be pivoted effortlessly via the handle 22.
- the locking bolt 29 is then reinserted and then sits in the bore 30 of the arm 7.
- the support roller head 14 can be replaced effortlessly.
- the structure of a deep rolling device 1 'according to FIG. 3 is very similar to that of the deep rolling device previously described.
- the arm 7 with the support roller head 14, which is articulated via the lever 20 on the arm 7 via the hinge pin 26, can be constructed exactly as already described for FIG.
- This lever 7 is in turn articulated by means of the hinge pin 24 and the tab 23 to an arm 6 ', the first ends 8' and 9 of the arms 6 'and 7 being connected to a piston-cylinder unit 10 which the Swivel movement of the arms should cause relative to each other and which generates the necessary rolling force.
- this has a slide guide 37 on the underside, on which one or more slides 35 can be arranged.
- the one or more slides 35 are displaceable in the direction of arrow 36.
- the carriages 35 carry deep-rolling roller heads 31, 32 and 33. Since several sliding carriages 35 are provided in the exemplary embodiment, the deep-rolling roller heads 31 to 33 are connected to one another via brackets 38.
- the deep rolling roller head 31 is here in the working position 34, while the deep rolling roller heads 32 and 33 are available for a roller head change.
- the roller head 33 with its associated slide 35 is over an arm 39 connected to the piston-cylinder unit 21 '.
- An inward and outward movement of the piston rod of this piston-cylinder unit 21 ′ brings about a corresponding displacement of the slide 35 and thus of the roller heads 31 to 33 in the direction of the arrow 36.
- any desired roller head can be brought into the working position 34 or removed from it will.
- the roller head located in the working position can be mechanically locked or held in working position 34 via a position control of the piston of the piston-cylinder unit 21 '.
