Definitions
- the invention relates to a deep rolling device of a deep rolling machine for crankshafts, which is designed in a scissor-type construction and in which two pivotable scissor arms opposite each other each carry a deep rolling roller head or a supporting roller head, the supporting roller head being provided with two axially parallel supporting rollers, the axes of rotation of which are in a common one Level lie, with a drive device that generates the closing and opening movement of the deep rolling device and the deep rolling force.
- Deep rolling devices of the aforementioned type are known from German patent DE 197 22 308 Cl, which discloses a deep rolling machine for crankshafts.
- one deep-rolling device can be assigned to each main and connecting rod bearing journal of a crankshaft.
- the construction of the deep rolling machine is designed so that when each deep rolling device is closed, the support rollers of the support roller head and then the deep rolling rollers of the deep rolling roller head are pressed against a main or connecting rod bearing journal.
- the support roller head and the deep rolling roller head each perform a swiveling movement in succession.
- the swiveling movement of the support roller and the deep roller head in the closing sense is associated with the risk that the support roller and the deep roller head may collide with the crankshaft in the area of an Olbund, since the clearances between the support roller and the deep roller head on the one hand and the two oil bundles of a main or connecting rod bearing journal, on the other hand, are scarce.
- the invention has for its object to design a deep rolling device of the type mentioned in such a way that the pivoting movement of the support roller and the deep rolling roller head in the closing sense cannot trigger a collision with the crankshaft in the region of an oil collar.
- the support roller head has at least one axial guide roller, which is arranged in the pivoting direction for closing the scissor arm carrying the support rollers, in front of the support rollers, the axis of rotation of which is perpendicular to the axis of rotation of the crankshaft and lies in a plane which is flush with the plane the axes of rotation of the support rollers form an acute angle, and their diameter is larger than the width of the support roller head and slightly smaller than the distance between the oil collars of a main or connecting rod bearing journal.
- the invention ensures that when the guide roller abuts against an oil collar, the deep-rolling device is aligned in the axial direction of the crankshaft.
- Such an orientation of the deep rolling unit ensures that the pivoting movement of the deep rolling roller head in the closing sense cannot lead to a collision of the deep rolling roller head with the crankshaft in the region of an oil collar.
- the axial guide roller is at a distance from this common plane.
- the outer contour of the axial guide roller can also have other shapes besides the classic cylindrical one, e.g. be spherical or composed of several geometric shapes.
- axial guide rollers can be provided instead of a single one, which are arranged next to one another and fill the free space which is circumscribed by two adjacent oil collars.
- Two axial guide rollers are customary, the outer width of which is dimensioned such that both axial guide rollers fit into the free space between the oil collars with little lateral play.
- Such an arrangement also has the advantage that the axial guide rollers are relatively small. This also reduces the lateral friction between the axial guide rollers and the oil collars.
- Fig. 1 shows a section through a deep rolling machine with a partial view of a
- crankshaft transport device with a deep rolling device assuming its open position in relation to an inserted crankshaft
- FIG. 3 shows a detail A from FIG. 2 on an enlarged scale
- Fig. 5 shows a section analogous to Fig. 3 with a special arrangement of the axial support roller
- a deep-rolling machine 1 is designed with a drive device (not shown) which serves to receive a crankshaft 3 introduced with a crankshaft transport device 2.
- the drive device produces the rotary movement of the crankshaft 3 about its axis 4 during the deep rolling of the main 5 and connecting rod bearing journals 6.
- the axis 4 is thus in the axis of rotation 7 of the drive device.
- the present exemplary embodiment is based on the deep rolling of a main bearing journal 5 of the crankshaft 3 limited, since this is sufficient to explain the subject matter of the invention.
- the main bearing journal 5 is assigned a deep rolling device 8 which, in a scissor-type construction with two scissor arms 9, 10, a scissor pivot point 11, one
- a deep rolling roller head 13 and a support roller head 14 is provided.
- the deep rolling head 13 and the supporting roller head 14 cannot be moved individually in the direction along the axis of rotation 4. Rather, they can only be set in certain planes which correspond to the respective position of the main bearing journal 5 or connecting rod journal along the axis of rotation 4 of the crankshaft 3 to be machined. Such a plane is shown for example in FIG. 3.
- 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 scissors of the deep rolling device 8 described above; the power device 16 the deep rolling force. By dividing the movements generated by the cylinders 15 and 16, a particularly narrow construction of the deep rolling device 8 is obtained.
- the deep rolling device 8 is articulated via an articulation point 17 to an angle lever 19 which can be pivoted about an axis 18.
- the angle lever 19 can be pivoted with the aid of a piston-cylinder unit 20.
- the piston-cylinder unit 20 By actuating the piston-cylinder unit 20, the deep-rolling device 8 is brought into and out of the working position.
- the deep-rolling machine 1 is designed so that when the deep-rolling device 8 is closed, the two axially parallel support rollers 21, 22 of the support roller head 14 and then the two deep-rolling rollers 23, 24 of the deep-rolling head 13 come to rest on the main bearing journal 5.
- the support roller head 14 performs a pivoting movement 35 in the counterclockwise direction around the articulation point 17 and the deep rolling roller head 13 performs a pivoting movement 36 in the clockwise direction about the scissor pivot point 11. Both pivoting movements 35 and 36 are carried out simultaneously and the closed position is reached at their respective ends, as shown in FIG. 2.
- the closed position corresponds to the working position of the deep rolling device 8.
- the axial guide roller 27 is arranged at an acute angle 37 between 0 and 45 ° and in a plane 38.
- the axis of rotation 41, about which the axial guide roller 27 can be rotated, lies in the plane 38 and is perpendicular to the axis of rotation 4 of the crankshaft 3 (FIG. 4).
- the plane 38 includes the axis of rotation 4 of the crankshaft 3, ie the plane 38 can oscillate about the axis of rotation 4.
- the level falls 38 in the sectional plane IV - IV, ie the acute angle 37 is 0 ° and the axial guide roller 27 has a lateral distance s from the plane 34 in which the two axes 32 and 33 lie.
- the two planes 34 and 38 run parallel to one another.
- the axial guide roller 27 is inclined at an acute angle 37 relative to the common plane 34 of the two axes 32 and 33 of the respective support rollers 21 and 22, which angle is greater than 0 °.
- This design means that when the support roller head 14 is pivoted into the closed position in the direction of the pivoting movement 35, the axial guide roller 27 rushes ahead of the two support rollers 21 and 22.
- the axial guide roller 25 enters the free space in front of the support rollers 21 and 22, which is circumscribed by the distance 29a of the two oil bundles 25 and 26 on the main bearing journal. In this way it is avoided that one of the support rollers 21 or 22 runs against one of the oil bundles 25 or 26 when the deep-rolling device 8 is closed.
- the axial guide roller 27 can have different shapes. In Figure 3, for example, it has a cylindrical shape. In FIG. 5, the axial guide roller 27 has a multiple contour, which is composed of a cylindrical 39 and a conical section 40. In addition, the axial guide roller 27 can also be configured crowned (not shown). In the case of bearing journals 5, which have a particularly large width 29a, instead of a single axial guide roller 27, two axial guide rollers (not shown) can also be arranged next to one another, one bearing against the oil collar 25 and the second against the oil collar 26. Due to the scissor design of the deep rolling device 8, the axial guide roller 27 also takes over the guiding of the deep rolling roller head 13 in the axial direction.
- the diameter 28 of the axial guide roller 27 is larger than the width 29 of the support roller head and slightly smaller than the distance 29a of the oil collars 25, 26 of the main bearing journal 5.
