Definitions
- the invention relates to a system for the precise mutual alignment and welding of the essential assemblies of a vehicle body to form a complete body during prototype production.
- assemblies are first welded together from the sheet metal parts of the body, e.g. Vehicle floor, stem, rear, side wall right / left inside, side wall right / left outside, whereby this list or subdivision into assemblies - depending on the vehicle type - can be different.
- the subdivision of a vehicle body into individual assemblies is determined by the designer at a very early design stage of vehicle development based on experience and in consensus with various positions of a vehicle manufacturer concerned with vehicle development and production.
- the individual assemblies are in turn composed of several sheet metal parts, which in their initial state are only so large that they can be handled manually. Due to this moderate size of the individual sheet metal parts of the assemblies and due to the open or even flat design of the individual assemblies, the individual sheet metal parts can be built in relatively simple devices. half of an assembly fix in position to each other and connect with each other by welding points. Combining the various assemblies into a complete body is more problematic, however, because of the large and weight-related unwieldiness of the various assemblies and because the body as a whole is a voluminous hollow body.
- DE 35 25 851 C2 shows a multi-part mounting unit for use in a system for the prototype production of first sample bodies.
- the essential parts of the known recording unit are composed of contour-lasered boards.
- the receiving unit adapted to the type of vehicle to be manufactured is designed in such a way that many of its individual parts can be reused despite the individual overall design after the receiving unit has been disassembled.
- Several receiving units individually designed according to the body shape at the clamping point are fixed and screwed onto a flat base plate and protrude from it at right angles.
- the receiving units are arranged on the base plate in such a way that the various assemblies to be welded together and large parts of the resulting vehicle body can be received and fixed precisely in the receiving units.
- the known literature is limited to a type-flexible design of the required receiving units themselves, but does not contain any information as to whether or, if so, how side walls can be accommodated in a manufacturing device in an exact position.
- the object of the invention is to show a plant for the prototype production of body shells, in which all the advantages mentioned below can be achieved in their entirety:>
- the proportion of type-specific components of such a prototype production system should be lower than before, and the production system should thus be given greater flexibility with regard to different vehicle types.
- prototype production should in principle allow greater closeness or relationship to later series production than previously, so that studies relating to series production at the prototype production stage are also possible. After all, prototype production itself should be carried out more efficiently than before.
- this object is achieved by a prototype production system which is designed according to the entirety of the features of claim 1.
- the idea of dividing the required workload into several workstations, which is known per se from series production, is in this case adopted in a special, prototype-specific manner for prototype production.
- the components of the prototype body are assembled in a precise, cage-like, stapling station and stapled through the cage openings.
- the already correctly positioned body parts of the body which is now inherently stable and only supported on the underside, but otherwise freely accessible, are fully welded together.
- This division not only makes the prototype production close to the series, but also makes the prototype production rational and ergonomically very cheap because the larger number of required welding spots can be carried out on the freely accessible body.
- the plant for prototype production is made up of various individual parts and plant components composed, which are largely designed as system-standardized building block elements, which can be assembled quickly and yet precisely in a different configuration due to a grid of plug-in and connection openings.
- the system can not only be set up inexpensively and in a short time, but can also be converted into a different type of vehicle for the production of a different type of vehicle.
- the required manufacturing accuracy and rationality of the system is created, on the one hand in universal, ie type-independent and on the other hand only in type-specific, ie only for a certain vehicle type, the multi-part assembly being created , type-specific recording units for their part consist largely of universally usable parts.
- FIGS. 1 and 2 are a partial, perspective views of the stapling station of the system according to FIGS. 1 and 2,
- FIG. 4 shows a single view of the welding station of the system according to FIGS. 1 and 2, 5 and 6 top view (FIG. 5) and cross section (FIG. 6) on or through a mounting plate provided with sockets, threaded holes and net lines,
- ⁇ a is an enlarged view of the detail Via from Figure 6,
- FIG. 7 shows an enlarged illustration of detail VII from FIG. 5, namely an axial view of a socket designed as an elongated hole to compensate for temperature expansions,
- FIG. 10 is a perspective view of a carrying skid for conveying a body placed on it.
- the prototype manufacturing plant for vehicle bodies 21 shown in FIGS. 1 and 2 presupposes that all essential assemblies or large parts of the body - they are referred to below as "assemblies" - have been prefabricated separately. The following description does not address this.
- these prefabricated assemblies are to be precisely aligned with one another and welded together to form a complete body.
- Prototype bodies with a greater or lesser number of advantages and disadvantages have already been manufactured with corresponding manufacturing systems.
- the prototype manufacturing system according to the invention described below which, however, achieves all of the following advantages: Rational prototype production. Less preparatory time and money required before prototypes of a particular vehicle type can actually be manufactured. Low proportion of type-specific components of such a prototype production system and thus greater flexibility of the production system with regard to different vehicle types.
- the prototype production system is provided with the following design features:
- two pairs of stations 1, 2 and 1 ', 2' are arranged one behind the other in a production line in the longitudinal direction 3 and are connected to one another for transport by a conveyor device - for example by a crane track 4.
- the first workstation 1, 1 'used in the direction of travel 3 serves to align and staple the assemblies, which is why it is called the stapling station below.
- the modules which have already been tacked are completely welded out, which is why these second work stations are referred to below as welding stations.
- the conveyor for connecting the workstations 1, 2, 1 ', 2' for transport purposes is designed as a bridge crane system with a raised crane runway 4 and a traveling crane 5 movable thereon. educated.
- the crane harness 6 attached to the load hook consists of a traverse running in the longitudinal direction 3 with load suspension cables attached at both ends.
- two pairs of stations 1, 2 and 1 ', 2' each consisting of stapling station 1 or 1 'and welding station 2 or 2', are arranged one behind the other in the transport-linked production line.
- the first pair of stations 1, 2 is designed for the mutual alignment and stapling of the assemblies, including the right and left side walls arranged inside the body 21, and the second pair of stations 1 ', 2' for the subsequent alignment and stapling of the two outer side walls.
- the assemblies of the body or the partially finished body rests on a frame-like support skid 23 during transport to the first station 1 or between successive workstations.
- the resulting body of the vehicle 21 is then received and held horizontally with vertical play but in a slip-resistant manner.
- Two longitudinal frame legs 26 of the supporting skid 23 each protrude beyond the vehicle body 21 in the front and rear in the longitudinal direction and are provided at the end with eyelets for attaching a crane harness.
- the stapling station 1, 1 ' shown enlarged in detail in FIG. 3, has a horizontal, flat base plate 7 on the underside and a vertical side wall 8, designed as a beam truss, on the right and left.
- the side walls can be moved on horizontal guide rails 10 in the transverse direction 24 and can be moved between a lockable working position on the one hand and a moved loading position on the other hand.
- the side walls 8 In the collapsed approach stood the side walls 8, these can be connected on the upper side by releasable and fixable connecting beams 9 to form a stable cage.
- Both the base plate 7 and the two side walls 8 are provided with a multiplicity of receiving units 18 adapted to the type of vehicle to be manufactured for the location-defined receiving and tightening of the assemblies within the stitching station 1, 1 '. Further details of the stapling station will be discussed in more detail below.
- the welding station 2, 2 ' also has on the underside a horizontal, flat mounting plate 30 which is also provided with a multiplicity of receiving units 18' adapted to the type of vehicle to be manufactured.
- receiving units 18' adapted to the type of vehicle to be manufactured.
- the receiving units 18 'of the welding station are limited to the underside of the body body 21 to be tensioned, so that the body body 21 accommodated in the welding station 2, 2' is freely accessible from the sides, from the front, from the rear and from above.
- Both the stapling station 1, 1 'and the welding station 2, 2' contain, on the one hand, universal, i.e. system components and device parts that can be used regardless of type and, on the other hand, type-specific, i.e. System components and device parts that can only be used for a specific vehicle type.
- the system components or device parts of the stapling station 1, 1 'mentioned below are as follows for the purpose of universal use of these components or parts educated. To a certain extent, these are parts of a modular system, from the different standardized "building blocks" of which workstations for different body shapes can be put together quickly and flexibly.
- the base plate 7 shown in more detail in FIG. 3 is provided with a multiplicity of sockets 14, 17 arranged in a regular grid and threaded bores 15 arranged therebetween and arranged according to the same grid.
- the authoritative grid is orthogonal and the same grid in the horizontal longitudinal (3) and transverse direction 24 and also in the vertical direction 28 - this will be discussed again below.
- the sockets are made very precisely and embedded in the base plate with the same precision.
- One type of socket 14 (shown enlarged in FIG. 6a) is provided with a cylindrical plug opening; it is used to fix the assembly parts without play.
- Another type of socket 17 (FIG. 7) has an oval, that is to say a slot-shaped opening; this socket serves to compensate for thermal expansion.
- the oval sockets are inserted into the mounting plate so that the long axis of the oval extends parallel to the transverse direction 24.
- the inserted parts can also be firmly screwed together using prepared threaded bores 15 or corresponding through holes 22 in the mounting plates 13 (for example FIGS. 5 and 6).
- the Plug pins 16 (FIG. 8) are cylindrical in their lower part and are inserted with this part into a socket of the mounting base, ie the mounting plate or the mounting tree.
- the upper part of the peg is also rotationally symmetrical and its largest diameter is exactly the same as the cylindrical part, but the upper part of the peg is in principle spherical with an attached truncated cone to make it easier to attach a heavy component.
- the base plate 7 or the build-up plate 30 of the stitching station 1, 1 'and the welding station 2, 2' and the build-up plate 13 or adapter plate 33 of both stations 1, 1'; 2, 2 'straight net lines 25 following the grid are incorporated.
- the incorporated network lines 25 run centrally through the sockets 14, 17 and the threaded bores 15.
- These mounting plates are also provided with sockets 14, 17 arranged with a grid and with threaded through holes 22 and can therefore be easily and precisely mounted in different arrangements on the base plate 7 using plug pins 16 and screws.
- the mounting plates are intended for receiving a group of receiving units 18.
- the horizontal outer dimensions of the mounting plates 13 are dimensioned in the longitudinal (3) and transverse directions 24 in accordance with the aforementioned grid, which is decisive for the position of the sockets 14, 17 and threaded bores 15.
- the sockets 14, 17 and threaded bores 15 in the mounting plates 13 are arranged eccentrically by half the grid dimension to the boundary edge of the mounting plates 13 which is parallel to the transverse direction 24.
- the mounting plates can be fixed by turning into a longitudinal or transverse position staggered by half the grid size using the sockets and plug pins.
- a carriage 11 can be moved on each of the guide rails 10.
- a vertically projecting, stiffly supported mounting tree 12 Arranged on each slide is a vertically projecting, stiffly supported mounting tree 12, which has a vertical flat side facing the base plate 7 on the side.
- At least two plug sockets 14, 17 and threaded bores 15 for mounting the truss-like side walls 8 are arranged in the assembly tree, corresponding to the above-mentioned grid in the vertical direction 28.
- the sockets 14, 17 attached to the assembly tree in the vertical direction with a grid are arranged, taking into account the common total height of the guide rail 10 mounted laterally on the long sides of the base plate 7 and the slide 11 movable on it, by an integral multiple of the grid dimension above the surface of the base plate 7 as a reference plane , This also facilitates exact height positioning of the truss-like side walls 8 to be mounted on the assembly tree.
- the specified working position is secured by a clamp.
- the opposite end of the horizontal travel path, the placement position need not be precisely predetermined and secured; it only has to be ensured that the carriage 11 does not move out of the end of the guide rail.
- the guide between the slide and the guide rail is designed as a precise and smooth-running roller bearing guide. It has to be precise because it determines the height position of the side walls and thus the accuracy of the assembly. It has to be easy to move so that the parts weighing tons can be moved manually by the worker without great effort.
- the travel path of the truss-like side walls 8 carried by the guide rails 10 and the slides 11 between the working position and the moved-off loading position is at least about 60 cm, but preferably about 1 m or more.
- the possibility of moving the side walls 8 away from the body creates a space that can be comfortably walked on by the worker between the mounting plates carrying the resulting body and the receiving units that they each project, on the one hand, and the side walls 8 on the other, which enables ergonomically favorable and rapid work.
- the right and left, truss-like side wall 8 are to be mentioned, each of which is designed as two torsion-resistant beam trusses that are mirror images of one another.
- the assembly beams of this beam framework save open, for the passage of welding tools suitable subjects.
- the course of the bar is roughly adapted to the course of the lateral outline and the position of the A, B and / or C pillars of the vehicle type to be manufactured.
- the two opposite, vertical flat sides of the beam trusses are machined plane-parallel.
- the side walls on the flat side facing the assembly trees 12 also have sockets 14, 17 and threaded holes 15 arranged with a grid.
- the side walls are machined flat in a horizontal plane and there are provided with a socket or plug pin and a connecting element at a point corresponding to the number and the required mounting position of the connecting bar 9.
- the length of the connecting bars 9 corresponding to the mutual spacing of the side walls 8 locked in the working position are only parts which can be used depending on the type. They are machined at their ends on the underside and are provided there with a plug pin or socket and with a connecting element for connection on the top side to the side walls 8.
- the connecting elements between the connecting bar 9 and the two opposite side walls 8 are each designed as quick-release fasteners.
- the connecting bars 9 must be loosened each time a finished body is changed and, after the assemblies for a new body have been inserted into the stitching station 1, 1 ', must be reassembled.
- the many receiving units 18 (FIG. 9) adapted to the type of vehicle to be manufactured are also designed as type-dependent special parts.
- the admission units are mounted directly on the side walls 8 or indirectly with the interposition of base-side mounting plates 13 or an adapter plate 33 on the base plate 7 or mounting plate 30 and protrude at right angles from them.
- the receiving units are each provided with a plurality of adapted receiving points 37 and a movable clamping arm 38.
- the mounting units mounted on the bottom it must be taken into account that gaps remain between them in such a way that the frame legs 26 of the support skid 23 for receiving the resulting vehicle body 21 can be lowered into the gaps in the vertical direction 28 without hindrance and lifted out of them.
- a mounting bracket 35 which can be screwed onto the supporting base and is of the same design for all receiving units 18, 18 'is provided as the foot.
- a support plate 36 is screwed onto this mounting bracket 35, which protrudes from the supporting base and is shaped with its contour facing the vehicle body 21 individually according to the respective local outline contour of the body part on the outside thereof and at at least two receiving points 37 on a possibly diagonally arranged, small area touched "selectively".
- the length of the support plate 36 from the mounting bracket 35 to the punctual receiving points 37 corresponds to the individually required distance of the body part from the supporting base.
- This support board can be used today in generally as a data record of existing body shape data using a data-controllable laser cutting system can be cut out of a sheet metal sheet in a rational and precise manner, even a space-oblique design of the contact surface of the receiving points 37 can be generated. A small machining allowance for post-processing is kept at the pick-up points. Only the final finishing of the recording points to the actual final dimension and the final shape of the same is carried out separately.
- a tension arm 38 is pivotally attached, which can be closed or opened by a tensioner 40 provided with a hand lever 42.
- the tensioning arm engages over the body part to be tightened in a mouth-like manner. It is individually shaped on the inside in accordance with the respective local contour of the body part.
- the tensioning arm is each provided with a shape-adjusted clamping thumb 39.
- fitting bores with an axially adjoining nut thread with a high degree of position accuracy are machined individually in accordance with the desired position of each mounting unit to be assembled.
- To mount the receiving units they then only have to be fixed by means of a fixing screw to the truss-like side walls or to the mounting plates 13 or adapter plate 33 already mounted on the bottom. This eliminates the need to align or calibrate the recording unit. It is only a final measurement with measurement proto- koll necessary.
- a receiving unit is not within the intended tolerance field, which occurs relatively rarely in the described procedure, it is conventionally measured after loosening and screwed into the desired position by means of a fitting bush on the mounting bracket 35 and another fitting screw; then the adapter bush is fixed with tack points on the mounting bracket.
- the welding station 2, 2 ' also contains a universally usable part, namely a freely accessible mounting plate 30, which is likewise provided with plug sockets 14, 17 and threaded bores 15 arranged in a grid-conforming manner. So that the lifting-movable mounting plate 30 of the welding station 2, 2 '- together with a type-specific, uniform adapter plate 33 - can be used universally, it is narrower in the transverse direction 24 than the narrowest vehicle body 21 and in the longitudinal direction 3 shorter than the shortest vehicle body.
- the larger adapter plate 33 is fastened on this mounting plate 30 and is also provided with plug-in sockets 14, 17 and threaded bores 15 arranged in a grid-conform manner.
- the adapter plate 33 is fixed in position on the mounting plate 30.
- the uniform adapter plate 33 of the welding station can only be used for specific types.
- the adapter plate 33 is therefore individually designed in terms of shape and size to meet the space requirements for the arrangement of all receiving units 18 'required on the bottom side for the type of vehicle to be manufactured and corresponds approximately to the outline contour of the type of vehicle to be manufactured.
- the body 21 accommodated in the welding station 2, 2 ' is only held on the underside and is otherwise freely accessible on all sides, which not only makes work easier when welding the filled assemblies, but also offers the possibility of adjusting the height of the body during welding to change and bring them into an ergonomically optimal position.
- the mounting plate 30 of the welding station 2, 2 ' is arranged on the top of a lifting device 31, which is designed as a scissor lifting table and is surrounded by a bellows to protect the worker.
- two laser scanners 32 are arranged in the walk-in area of the welding station 2, 2 '- diametrically opposite one another, which are aligned with their scanning beam on the lifting device 31 and detect all objects in the detection area of the scanning beam.
- the horizontally arranged scanning Level 34 is approximately at calf height.
- the scanning beam covers an angular space of at least about 90 °.
- the laser scanner is coupled to the control of the lifting device in such a way that the latter can only be actuated if the laser scanner does not detect any other objects, in particular no legs of a worker, apart from the permanently installed lifting device. The lifting device can therefore only be actuated when all workers have emerged from the detection area of the laser scanner.
