The main body 2 can reinforcing elements 10 have, for example in the form of reinforcing ribs, for example, in the xz plane and thus perpendicular to the plane of the body 2 extend.

A key aspect of the present invention is the provision of a support and guide device 30 for backlash-free support and guiding in the opening 20 recorded coupling element 40 for achieving a torsion-proof coupling of a positioning device 1 at a further positioning device 1 in a positioning device 100 ,

Further key aspects of the present invention are the specific design of the opening 20 and / or the supporting and guiding device 30 with the first and second support and guide elements 31 respectively. 32 ,

The opening 20 as such, according to the invention to a recording of the coupling element 40 trained with game, although also under thermal load, thereby rotation, torsion and / or de-stressing the coupling of the positioning 1 over the coupling element 40 to ensure. This is the opening 20 dimensioned with dimensions that are larger than the dimensions of the positioning device 100 associated coupling element 40 ,

The support and guide elements 31 and 32 are in a first area 21 the opening 20 , which is the second edge 2-2 of the basic body 2 facing, arranged and cover there the opening 20 partially.

On the other hand, a second area remains 22 the opening 20 , which is the second edge 2-2 of the basic body 2 turned away, the first edge 2-1 of the basic body 2 facing it, uncovered.

The 8th to 15 show embodiments of the positioning device according to the invention 100 using various embodiments of the positioning device according to the invention 1 and in particular using a stand 80 with frame 81 and pillar 82 for receiving and holding first and second retaining rails 60 and 70 to which the positioning devices according to the invention 1 with their recordings 3 and 4 rest.

These and other features and characteristics of the present invention will be further elucidated with reference to the following statements:

First of all, some general aspects are explained and, inter alia, the following changes proposed to be carried out alternatively or in combination according to the invention compared with the previous procedure are proposed:

The main body 2 has a redesign, is limited to the minimum and / or designed so that even in spite of the considerable heat and the constant temperature change no distortion and its consequences such as cracks, changes in shape, etc. can occur.

The elimination of crossbars, nodes and all elements that are obstructed by an expansion, is decisive, is only possible by the present invention and provides one of their great advantage.

The construction and / or the shape of the individual parts, which as a whole a component holder in the sense of the positioning device according to the invention 1 were determined, were chosen or determined, and also on the basis of results from long-term tests, that no delay forms by the free expansion path.

At most, an elongation and / or material-related elongation over the area stretching may occur, but have no effect on the dimensional stability and the positioning accuracy.

A symmetrical design additionally distributes all acting forces evenly.

Generously introduced radii instead of small corners additionally convey excess stresses.

There is an improvement of the thermal loads.

Instead of previous cross struts a box design are only supports for the mechanical loads in the sense of ribs 10 brought in.

The number and position of these lateral supports 10 results from the number and location of the support points 5-1 a recording 1 , In individual cases, however, it is equivalent if a support between two support points 5-1 is attached, if not a large distance from each other own, in particular taking into account the respective component shape and the weight of the component.

A respective lateral support, which in the context of the invention, a reinforcing rib 10 As reinforcing element has or forms, may preferably all the way up to receiving edge, so for example up to the upper edge 2-1 be drawn, otherwise a change in shape due to mechanical influences in the mold when placing a component 15 caused by a robot or by vibration. This applies in particular to the case in which the reinforcing ribs 10 as lateral support not up to the upper edge 2-1 to be pulled. In this case, a deformation from the end of the support by the reinforcing element can be due to a longer mechanical action 10 up to the upper edge 2-1 take place.

An improvement of the mechanical load capacity is achieved.

Alternatively or additionally, all recording areas 2-9 at positioning devices 1 in the form of pick-up points 5-2 or centering pins 5-1 at positions of the receiving areas 2-9 be relocated, which no longer have any changes.

So far, however, was a connection of recording pins, etc. at the affected default.

An essential aspect of the invention is the provision of two parallel cuboids as supporting and guiding elements 31 . 32 a supporting and guiding device 30 , Other shapes are possible. The support and guide elements 31 . 32 are in particular on or on a locking bar - namely the coupling element 40 - The positioning 1 and are especially on the platen 50 assembled.

The support and guide elements 31 . 32 have the function of a rotation of the positioning 1 because the shots 3 . 4 the positioning devices 1 in the positioning device 100 only loose on the carrier rails 60 . 70 rest.

In particular, by the support and guide elements 31 . 32 are the small size and reduced weight of the positioning 1 possible.

So far, the anti-rotation over a V-profile of the recordings 4 , This procedure required an elongated box-like design with several parallel walls and transverse walls and a correspondingly increased weight.

Due to the relatively narrow free space of a maximum of 1 mm between the continuous coupling rod 40 and the cuboids 31 . 32 In addition, there is another advantage in the form of a positive clamping on the positioning of the coupling rod 40 ,

Previously, deposits of a layer of zinc on the contact points often caused a slight bond between the components during prolonged production 15 and the positioning devices 1 , whereby the positioning devices 1 when removing finished components 15 - z .B. through the robots - were lifted upwards and when tearing off the connection to the mounting rails 60 . 70 fell and could damage these and other parts of the plant.

The locking over the cuboid 31 . 32 can also be used with so-called dummies.

These pursue the purpose of stabilizing the tie rods 40 if no or not all positioning devices 1 were fitted so as to prevent deformation.

Without the new anti-twist device via the support and guide device 30 The dummies can become skewed over time and leave the set position due to the vibrations. This raises the coupling rod 40 on and the dummies slipped to the inside of the goods carrier. Deformations are the result.

In addition, there is an additional expense for the maintenance of the coupling rods 40 or by disturbances of subsequent productions.

These problems are prevented according to the invention.

Below are details of the embodiments of the 1 to 15 :

The positioning device according to the invention 1 for a sheet metal component 15 consists of a basic body 2 , on one side 2-2 a recording device 3 . 4 he carries over on rails 60 . 70 the underlying positioning device can be supported, and on the other side 2-1 at least one holding device 5 having for the sheet metal component.

The main body 2 Eg consists of a vertical wall, so extends in the figures in the z-direction. On the wall 2 are both the receiving device 3 . 4 as well as the holding devices 5 arranged.

Vertically directly below a holding device 5 can be a reinforcing rib 10 to the lower edge 2-2 of the basic body 2 be educated.

It can also be on the front 2-5 and on the back 2-6 of the basic body 2 vertically below a respective holding device 5 one reinforcing rib each 10 be educated.

The main body 2 can in particular perpendicular to the receiving device 3 . 4 be aligned.

The recording device 3 . 4 may consist of two spaced profiles, wherein a receiving device 3 as a support 8th acts and the other recording device 4 as a fixed camp 9 is trained.

The support 8th can as one to a corresponding retaining rail 60 the underlying positioning device 100 be formed open U-profile.

The camp 9 , which is also referred to as a guide bearing, can as one to a corresponding retaining rail 70 the underlying positioning device 100 enclosing profile or be designed as an open profile. In this case, any shapes are conceivable over which a guide can be made according to the trained carrier rails. Also conceivable are open, partially enclosed or fully enclosed forms for the receiving means 4 , For example, with a triangular shape in cross section or in the form of round tubes or the like.

There may be fasteners 13 be formed over which the positioning 1 at the respective holding rail 60 . 70 can be variably fixed in a rail longitudinal direction.

In the following, some aspects essential to the invention are presented:

By the use according to the invention of the guiding and supporting device 30 with the first and second guide and support elements 31 and 32 is it possible the opening 20 to run as large as needed, without the disadvantages associated with conventional positioning or positioning devices.

Here is the size of the opening 20 not decisive for the torsion and torsion protection, as well as the stress-free coupling. This is realized according to the invention by the interaction of the coupling element 40 , for example in the form of a coupling or connecting bar or bar, and the guiding and supporting device 30 ,

In conventional positioning devices and positioning an anti-rotation over a V or angle profile is intended as a receiving means, but with the corresponding disadvantages of the complex box design with the corresponding disadvantages in terms of size, in particular length in the direction of the support rails 60 . 70 , Increased cost of materials and the risk of mechanical stress under thermal alternating load.

Due to the constant change of temperature, distortion and cracks usually occur, which of course also influences the profile of the images 4 ,

Other factors such as vibration also have a detrimental effect on the conventional long-form assembly.

As an additional measure, this has so far been a small opening 20 introduced and served in the train of thought of the designers as an end stop, if the profile 4 a possible rotation or position change of the recordings would not be enough.

The partially continuous skewing until the end stop has traditionally given rise to further problems, e.g. obliquely run-in dummies and devices that could no longer be repaired, as well as difficult conditions during the set-up procedure or changing of the devices and the resulting increased maintenance and replacement intervals.

The recesses or openings 20 are within the meaning of the invention, an additional improvement in terms of handling, change, exchange of positioning 10 as recordings and has no effect.

As a core of the invention are thus the guiding and support means 30 the guiding and support elements 31 and 32 to watch.

The invention possible elimination of cross braces, nodes and the like is relevant to the present invention.

Failure to comply with this will result in self-deformation resulting from the occurrence of cracks, etc., due to the effects of temperature and the like. This is the main problem in all conventional box-shaped positioning and positioning devices and thus without free expansion path in the longitudinal axes the present invention is achieved. In this case, according to the invention, corresponding positional changes due to thermal alternating load are avoided.

As an additional development, a symmetrical embodiment is particularly suitable for operation.
