Definitions

• the present invention relates to a method for producing a split bearing arrangement, in which in several processing stations a bearing upper part is separated from a bearing base part integrally connected to it by introducing a force via a fracture separation process in a predetermined fracture plane and then again by a screw connection having at least two screws mite_Lnander is connected.
• the invention further relates to a manufacturing device for producing a split bearing arrangement, in which the workpiece consisting of a bearing base part and a bearing upper part integrally connected thereto has at least one break separation station for separating the bearing upper part from the bearing base part and a screwing station for reconnecting the bearing upper part to the bearing base part by means of at least two Screws having screw connection is supplied.
• Bearing arrangements of the type mentioned above have, for example, workpieces such as crankcase connecting rods or the like. on.
• the object of the present invention is to provide a procedure and a production device in which damage to the screws and assignment errors in relation to the upper bearing parts are completely excluded.
• this object is achieved according to the invention in that the bearing base part and the bearing upper part are fixed on an adapter device conveyed from processing station to processing station and the bearing upper part is arranged at least in some operations in the processing stations via an adapter device arranged on the adapter device and outside of it Area of the screw connection to the upper bearing part, retractable auxiliary support is held.
• a transport device is provided, via which an adapter device carrying the workpiece is conveyed from a processing station to at least one subsequent processing station, the adapter device being equipped with a retractable auxiliary support, which is thus fixed on the adapter device is arranged that it acts outside the screw connection on the upper bearing part of the workpiece.
• the invention is based on the idea of combining the advantages of conventional procedures and production facilities in which the screws are arranged before the fracture separation process with the advantages of a fracture separation method without screws.
• auxiliary support assigned to the two bearing parts over the entire production sequence, which ultimately takes over the task of inserted screws in a novel manner and ensures that the respective upper bearing part remains on the associated bearing base part over the entire production process.
• the auxiliary support is not assigned to a specific station, but remains due to its arrangement on the adapter device over the entire manufacturing process in the area of the two bearing parts and thus on the workpiece.
• the auxiliary support can be designed in many different ways. It can consist of one or more support elements which, depending on the shape, engage at a suitable point on the upper bearing part. It can be operated mechanically, pneumatically or also hydraulically.
• the use of adapter devices for receiving and holding workpieces in manufacturing processes with a number of processing stations in the field of production lines is already known.
• the use in a method for producing a split bearing arrangement and the arrangement of an auxiliary support on the adapter device and its special arrangement in connection with the delivery or reset option is completely new and opens up a multitude of surprising possibilities for the course of the method.
• One of these options opens up the possibility of delivering and resetting the auxiliary support.
• the upper bearing part For certain operations and in particular when transporting from one processing station to the next processing station, it is necessary for the upper bearing part to be held firmly on the bearing base part.
• the workpiece can be fed directly to the screwing station after the break separation process.
• the bearing base part and the upper lab part are subjected to a loosening and cleaning process in the plane of the fracture after the fracture separation process.
• This loosening and cleaning process can be designed in many different ways.
• a vibrating or impact device can be provided in the respective station, which acts on the upper bearing part and brings it into rapid contact with the bearing base part in the fracture plane.
• metal particles generated and loosely located in the fracture surface can be removed by the fracture separation process.
• This process can be supported by means of a blow-off, suction or brush device.
• the upper part of the bearing In the phase of vibration or impact impact, the upper part of the bearing must be fixed exactly in relation to the bearing base part parallel to the fracture plane and at the same time kept loose perpendicular to the fracture surface. It is expedient to provide a fixing device which has fixing and holding mandrels which can be inserted into the bores for the screws. During this process, the auxiliary supports are withdrawn, so that for the Cleaning process by blowing, vacuuming or brushing the upper bearing part can even be moved relatively far from the bearing base part to form a gap, without the connection between these two parts being broken and thus the assignment errors mentioned at the outset can occur.
• the fixing and holding mandrels can be arranged in any way.
• break separation notch In practice it has proven useful to place a so-called break separation notch in the workpiece before the break separation process to define the break separation plane.
• This notch can be made in a variety of ways. It is advantageous if the notch is made by laser in the area of the fracture separation plane.
• break separation notch prefferably introduced by means of the laser in a separate station which is arranged directly in front of the break separation station.
• a particularly advantageous arrangement results, however, if the loading and unloading station, the screwing and laser station, and the break separation station and the detaching and cleaning station are each combined to form a double station in such a manufacturing device. In this way, different work steps can be carried out simultaneously in the different stations, so that downtimes of the respective station are reduced to a minimum.
• a manufacturing facility designed in this way is therefore in able to process a larger number of workpieces per unit of time without loss of quality than would be possible with a conventional series connection of processing stations and a gradual transfer of workpieces to be processed.
• Figure 1 shows an embodiment of an adapter device with a workpiece in the form of a crankcase with an upper part of the crankcase engaging, i.e. auxiliary support delivered,
• FIGS. 3a to 31 schematically show the upper bearing part of the crankcase according to FIGS. 1 and 2 with auxiliary support in different phases of the processing and in different processing stations of the production device according to the invention
• FIGS. 1 and 2 The exemplary embodiment of an adapter device 1 shown in a vertical section in FIGS. 1 and 2 rests on a transport device 2 and is essentially trough-shaped, ie U-shaped in cross section.
• the workpiece in the form of a crankcase 3 rests in the interior of the trough-shaped adapter device 1 and (viewed in the plane of the drawing) is equipped with a number of bearing arrangements 4 arranged one behind the other, each of which consists of a bearing base part 5 and a bearing upper part 6.
• crankcase 3 rests on its underside on counter stops 7 and bears against a counter stop 8 on the side facing the bearing arrangement 4.
• the adapter device On the side opposite the bearing arrangement 4, the adapter device is equipped with two clamping cylinders 9, by means of which the crankcase 3 can be pressed against the counter stops 7 and 8 and can thus be clamped in the adapter device.
• the upper bearing part 6 In order to divide the bearing arrangement 4, the upper bearing part 6 must be separated from the bearing part 5 integrally connected to it along a fracture plane 10. This is done by a fracture separation process known per se in a so-called fracture separation station, in which a fracture force is introduced into the bore of the bearing arrangement 4 in a known manner via a fracture separation mandrel, which is usually divided into two.
• FIGS. 1 and 2 on the side of the adapter device 1 opposite the clamping cylinders 9, support punches 11 are provided at an acute angle to one another, which are arranged at the front end of support cylinders 12, which together form the auxiliary support 13 for the upper bearing part 6 ,
• FIG. 1 shows the auxiliary support 13 in the position that engages the upper bearing part, that is to say in the delivered position
• FIG. 2 shows the support plunger 11 of the auxiliary support 13 in the retracted position, that is to say lifted off the upper part 6 of the bearing.
• the upper bearing part 6 is held on the bearing base part 5 after the fracture separation process has been carried out by a screw connection having two screws.
• crankcase prepared in this way is then conveyed by means of the transport device 2 via the adapter device 1 into the first station of the production device, in which 10 notches 14 are made in the fracture plane.
• This technology is known and can be done in a variety of ways, but preferably by removing material by means of a laser.
• FIG. 3a This process is shown schematically in FIG. 3a.
• the auxiliary support 13 is withdrawn in this phase.
• main supports 15 are delivered before the subsequent fracture separation process, which, in a known manner, act flexibly on the upper bearing part 6 and prevent a so-called rotational fracture during the fracture separation process.
• the auxiliary support 13 is first delivered and then the main support 15 is withdrawn, as is shown schematically in FIG. 3c.
• the Auxiliary support 13 so that the upper bearing part 6 already separated from the bearing base part 5 in this phase cannot detach from the bearing base part 5 and cannot be confused with another upper bearing part.
• a fixing device 16 is delivered, as shown schematically in FIG. 3d.
• the fixing device 16 has two fixing and holding mandrels 17 which are connected to one another via a yoke 18.
• a vibrating or bouncing device 19 is also arranged.
• the fixing and holding mandrels 17 are inserted into the bores for the screws in a further working step and in this way the upper bearing part 6 is fixed exactly in position relative to the bearing base part 5 parallel to the fracture plane 10 and at the same time held loosely perpendicular to the fracture plane ,
• the auxiliary support 13 is then withdrawn and the vibrating or bouncing device 19 is brought in and brought into contact with the upper bearing part 6, as is shown schematically in FIG. 3e.
• the vibrating or bouncing function is then carried out and any metal particles adhering to the fracture plane are released.
• the auxiliary support 13 is then moved back in and the bearing upper part 6 is thus precisely fixed relative to the bearing base part 5.
• the Vibrating or bouncing device 19 is uncoupled and the fixing device 16 is withdrawn.
• the upper bearing part 6 is always held precisely on the bearing base part 5, so that not only are the mix-ups described at the outset excluded, but it is also ensured that the upper bearing part 6 is held securely in one position on the bearing base part 5 , which corresponds exactly to the situation before the breaking process, ie the elevations and depressions of the fracture surface of one part correspond precisely with the depressions and elevations of the fracture surface of the other part.
• This situation is also ensured according to the invention over the entire course of production, since the upper bearing part on the bearing base part is held in a precise assignment and position either by the auxiliary support 13 or (as shown in FIG. 3e) by the fixing and holding mandrels 17.
• Another advantage of the procedure according to the invention is that the screws are only fed and tightened after the fracture separation process has been completed, so that a high-quality screw connection is always ensured. Damage to screws or even bending of the screws during the break separation process is therefore excluded.
• the auxiliary support is withdrawn and the crankcase machined in this way is fed to a further operation via the adapter device 1 and the transport device 2.
• a so-called carousel arrangement 21 was chosen as the central transport device 2, on the circumference of which the various stations are arranged.
• the transport from one station to the next station is indicated by arrows in FIG.
• the sequence results from the position numbers given in a circle, which in addition to the various stations also indicate the sequence on the carousel arrangement.
• sequence for the manufacturing facility indicated in FIG. 4 is as follows:
• Adapter device used, aligned and clamped by means of the clamping cylinder.
• the auxiliary supports are in the retracted position (see FIG. 2).
• the adapter device with the f "estgespannten workpiece on the carousel assembly is conveyed (position 2) and from there the laser station (position 3) is supplied.
• the adapter device with the workpiece is placed on the Carousel arrangement is conveyed back to position 4 and moved by rotating the carousel arrangement to position 5, from which it is then fed to the break separation station (position 6) and, after the break separation, to the release and cleaning station (position 7).
• the adapter device with the broken and cleaned workpiece then returns to the carousel arrangement (position 8) and by rotating the carousel arrangement to position 9, from which the adapter device with the workpiece is then fed to the screwing station (position 10), in which the screws are screwed in and tightened with a predetermined torque.
• the adapter device is fed to the unloading station (position 12) via position 11 on the carousel arrangement. There the finished workpiece is removed from the adapter device and removed.
• the sequence can be selected in such a way that in the period in which a workpiece in the laser station is equipped with a break separation notch, a previous workpiece already equipped with a break separation notch is subjected to a break separation process in the break separation station and in the release process. and cleaning station of any metal particles can be exempted. In this way, downtimes in the individual stations can be reduced and the number of workpieces per unit of time increased.
