Description

Pressure device for a clamping system

Description

The invention relates to a pressure device of a clamping system, wherein the clamping system has a tensioner and attached to the tensioner pressure device comprises a clamping head. The pressure device transmits the clamping force of the tensioner on the chuck. For this purpose, the pressing device on a Andruckarm, wherein the Andruckarm is at one end in operative connection with the tensioner and at the opposite free end has a slot in which a mounting rod for the clamping head is longitudinally displaceable and rotatable. This mounting rod makes it possible to fix the clamping head longitudinally displaceable and rotatable at the free end of the Andruckarms.

Such a clamping system with pressure device has the disadvantage that the manufacturing use of the clamping system for clamping of production-related standard parts is extremely limited, since the clamping area around the tensioner around for clamping standard parts is minimal. In addition, the degrees of freedom in longitudinal displacement and rotational direction around the mounting rod provide no security against misalignments because the clamping system does not maintain the pre-adjusted positions safely. Finally, for any application that goes beyond the tensioning clamping range of the known clamping systems, expensive special constructions to fix standard parts for measuring and / or testing by clamping or pressing in test equipment construction. Thus, only special constructions and custom-made products can meet the corresponding additional requirements, which additionally burden the construction and production costs for vehicle components.

For a secure clamping of standard workpieces only the adjustability of the clamping pressure of a clamping system is necessary. It therefore exists u. a. the need for the further two degrees of freedom, such as longitudinal displaceability and rotatability, to be embodied as fixable positions in order to reduce the readjustment effort. This requirement can not be solved by the universal clamping tool known from US Pat. No. 4,747,588, since the degree of freedom of the adjustability of the clamping heads does not assume any fixed positions in any such readjusting of the clamping pressure.

The object of the invention is to provide a pressure device of a clamping system that allows different clamping positions using standard parts, these predetermined clamping positions can be maintained without readjustment in a necessary readjustment of the clamping pressure. Another aspect of the invention relates to the extension of the

Range of application or the enlargement of the possible clamping range in each case taking into account the reproducibility with the new pressure device.

This object is achieved with the subject of the independent claims. Advantageous developments of the invention will become apparent from the dependent claims. According to the invention, a pressure device is provided which has a pressure arm and a clamping head. The Andruckarm the pressure device has at one end a slot. In this slot, a mounting rod for the clamping head is longitudinally displaceable and rotatable, wherein the mounting rod fixes the clamping head longitudinally displaceable and rotatable at the free end of the Andruckarms. In addition, the pressure device according to the invention has an anti-rotation lock securing the angle between the clamping head and the pressure arm, with an anti-rotation plate and a safety pin.

This pressure device has the advantage that due to the rotation, the once set angular position of the clamping head is fixed in relation to the Andruckarm so that the readjustment can fully concentrate on the setting of the clamping pressure. By preventing rotation with anti-rotation plate and safety pin thus the reliability of the clamping system is improved when adjusting and readjusting the clamping pressure, since the risk of changing the angle once set even with multiple readjustment of the

Clamping pressure is maintained. In addition, since the anti-twist device can be standardized, retrofitting is possible in all existing clamping systems in order to increase their positioning reliability in the production process.

In a preferred embodiment of the invention, the anti-rotation plate is arranged orthogonal to the slot of the pressure device and carries on its upper side the mounting rod and the securing pin, which projects spaced from the mounting rod in the slot of the Andruckarms. In addition, the anti-rotation plate can have the clamping head and define the angle between the clamping head and the pressure arm, wherein this defined angle is secured by the securing pin.

Such an embodiment of the anti-rotation has the advantage that the anti-rotation plate with clamping head forms a unit which is rotatably connected via the mounting rod with the Andruckarm, wherein the securing pin ensures the set angle to Andruckarm. Preferably, the anti-rotation plate and the chuck form a one-piece component. This one-piece has the advantage of being on

Connecting elements between anti-rotation plate and clamping head can be omitted, which simplifies the retrofitting of existing clamping systems and cheaper.

In a preferred embodiment of the invention are the

Secured spigot and the clamping head opposite each other with respect to the mounting rod on the anti-rotation plate. In this case results in a rectilinear alignment of the clamping head with respect to the Andruckarm.

In a further preferred embodiment of the invention, the anti-rotation plate has a curved Lochrasterraupe opposite to the clamping head with respect to the mounting rod for defining and securing the angle between the clamping head and Andruckarm. In this case, the securing pin of the anti-rotation plate can be fixed in the perforated grid bead. Thus, it is possible that the securing pin allows a grid of angles between the clamping head and Andruckarm by the predetermined positions in the Lochrasterraupe. Such a perforated grid crawler has the advantage that the individual possible positions of the securing pin can be reliably fixed. In a further preferred embodiment of the invention, the anti-rotation plate has a curved slot slot opposite to the clamping head with respect to the mounting rod for defining and securing the angle between the clamping head and Andruckarm. In this case, the securing pin is fixable in the slot slot. This has the advantage that any intermediate angle can be secured by the securing pin. However, the adjustment of the angle or the pre-assembly of the angle is more complicated than with a predetermined perforated grid bead in the anti-rotation plate.

In a further embodiment of the invention, the pressure device for increasing the angular position between the clamping head and Andruckarm on an adapter plate, wherein the

Adapter plate is arranged orthogonal to the slot between the Andruckarm and the anti-rotation plate with clamping head. With such an adapter plate, the adjustability of the angle, which is already predetermined by the curved slotted slot or the bent perforated grid bead in Verdrehsicherungsplatte can be further increased by the mounting rod in order from bottom to top the anti-rotation plate with clamping head, the adapter plate and mechanically connecting the free end of the Andruckarms together. For this purpose, a securing pin is provided on the upper side of the adapter plate, which engages in the slot of the Andruckarms, while a second securing pin engages in the form of a releasable connecting element on the underside of the adapter plate in the curved slot slot or the curved Lochrasterraupe the anti-rotation plate with clamping head.

For this purpose, in the adapter plate has a through hole for the mounting rod and spaced from a bore for the Secured pins provided. In addition, the adapter plate has at least one further through hole, which is arranged on a circular line around the through hole for the mounting rod, wherein the circular line has a radius corresponding to the distance between the mounting rod and securing pin. Instead of a lower second securing pin, the further through hole of the adapter plate can have a releasable connecting element for defining and securing the angle between the pressing arm and the clamping head and for mechanically connecting the anti-rotation plate and the adapter plate. This connecting element may preferably be a screw which engages in a provided thread of the further through hole of the adapter plate.

Furthermore, it is provided that the clamping head is fork-shaped, since this type of clamping head opens up a wide field of application in the mounting of standard production parts in production and testing by clamping.

In order to expand the clamping range for the new pressure device, the pressure device has a boom. This boom extends the Andruckarm. For this purpose, the boom on a clamped end on a mounting rod and a securing pin, which are arranged and fixed in the slot of the Andruckarms. On the opposite free end of the boom through holes and / or threaded holes for a second mounting rod and a second securing pin for receiving the anti-rotation plate with clamping head and / or for receiving the adapter plate.

Such a cantilever may preferably be provided in five standardized lengths to provide correspondingly removed anti-rotation plates with chuck in several standard Sized lengths and to further increase the possibilities of variation of the clamping system. Finally, the adapter plate may be formed differently to increase the angular range for the left and right sides of the Andruckarm. With the help of such standardized additional parts, the range of application of conventional clamping systems can be significantly expanded, wherein the detectable or clampable volume range of standard components is significantly increased compared to conventional clamping system:

In summary, the invention provides the following advantages over systems known in the art.

1. A cost saving through simplification and standardization of the construction as well as a renunciation of further detailing of existing systems;

2. a cost savings in the production by standardized elements for the new pressure device, so that instead of special designs, a mass production is possible;

3. a cost saving during assembly through predefined standardized processes in the modular system;

4. a cost saving in the maintenance and modification service, since only standardized parts are used and thus an inexpensive interchangeability of elements of the clamping system is made possible; 5. a cover of a large clamping area around the conventional tensioner with new standard parts of the new clamping system.

The invention will now be explained in more detail with reference to the accompanying figures.

Figure 13 shows a schematic plan view of a clamping system and the possible adjustable clamping range of a clamping head of the pressure device.

Figure 1 shows a schematic perspective view of a clamping system 1 with a pressure device 5 of a first embodiment of the invention. The clamping system 1 has a tensioner 9 and a pressure device 5, wherein the pressure device 5 via a Andruckarm 11 of Andruckvor- direction 5 is in operative connection with the tensioner 9. The tensioner 9 of the clamping system 1 has in this first embodiment of the invention, a clamping lever 33 which engages with a clamped end 12 of the Andruckarms 11 and exerts a clamping pressure in the direction of arrow A on the free end 13 of the Andruckarms 11 when the clamping lever 33rd is transferred in the direction of arrow B from a rest position not shown in the clamping position shown. However, the force exerted by the clamping lever and the tensioner mechanical clamping force on the pressure device can also be applied hydraulically, pneumatically and / or electromechanically by appropriate clamping devices of the clamping system. The pressure arm 11 has a slot 14 in the region of the free end 13 of the Andruckarms 11, wherein in the slot 14, a mounting rod 15 is arranged longitudinally displaceable. The mounting rod 15 is fixedly connected to an anti-rotation plate 16, which is orthogonal to the axis 34 of the mounting rod 15.

This anti-rotation plate 16 has in this embodiment of the invention, a fork-shaped chuck 10 on one end and a curved Lochrasterraupe 18 on the relative to the mounting rod 15 opposite end of the anti-rotation plate 16. In the perforated grid bead 18, a securing pin 17 is fixed, which projects from the fixing rod 15 at a distance into the oblong hole 14 of the pressing arm 11.

The anti-rotation plate 16, in cooperation with the securing pin 17, ensures that the position of the fork-shaped clamping head 10 is maintained during a readjustment of the contact pressure. The rotation of the fork-shaped clamping head 10 about the axis 34 of the mounting rod 15 is practically excluded due to this rotation by the anti-rotation plate 16 and the securing pin 17, so that here shown rectilinear alignment of the fork-shaped clamping head 10 is completely retained in the Andrucknachjustage.

FIG. 2 shows a schematic side view of an anti-rotation lock plate 16 with securing pin 17. This securing pin 17 is arranged at a distance a from a through hole 21 for the fastening rod shown in FIG. The securing pin 17 is arranged perpendicular to the upper side 37 of the anti-rotation plate 16. The securing pin 17 is fixed by a screw 35, which engages from the underside 38 of the anti-rotation plate 16 with an internal thread 36 of the securing pin 17. On the underside 38 of the anti-rotation plate 16 projects out of the clamping head 10, which is opposite to the securing pin 17 with respect to the bore 21 for the mounting rod.

Figure 3 shows a schematic plan view of an anti-rotation plate 16 with chuck 10. The anti-rotation plate 16 has a central through hole 21 for the mounting rod. In the modification shown in FIG. 3, the anti-rotation plate 16 has a perforated scanning bead 18 on an adjustable clamping region 39, wherein the adjustable clamping region 39 has a radius r which corresponds to the distance a shown in FIG. The shown in Figure 2

Securing pin 17 can be fixed in one of the positions of the hole pattern and thus define and secure an angle αi for the alignment of the clamping head 10 with respect to the above-mentioned Andruckarm 11.

Figure 4 shows a schematic plan view of a modified anti-rotation plate 16 with chuck 10. The modification is that instead of the curved shown in FIG Lochrasterraupe 18 a correspondingly curved slot slot 19 is arranged. With this slot slot 19, the angle αi between the chuck 10 and the above-mentioned Andruckarm 11 of the pressure device 5 can be continuously secured by a corresponding positioning of the securing pin in the slot slot 19.

Figure 5 shows a schematic perspective view of the clamping system 1 according to Figure 1 with preset and secured angle αi between Andruckarm 11 and clamping head 10. The size of the angle αi depends on the size of the anti-rotation plate 16 and the introduced there bent slot slot or the curved Lochrasterraupe , The other components with the same functions as in the preceding figures are identified by the same reference numerals and not discussed separately.

FIG. 6 shows a schematic perspective view of a clamping system 2 with a pressure device 6 according to a second embodiment of the invention. Components having the same functions as in the preceding figures are identified by the same reference numerals and are not discussed separately. The difference from the embodiment according to FIG. 1 and FIG. 5 is that an adapter plate 20 is arranged between the pressure arm 11 and the angle-adjustable anti-rotation plate 16. With this adapter plate 20, an additional angle α _{2 is added} relative to the longitudinal extent of the Andruckarms 11 to the angle αi, so that angular positions α are achieved with 0 ≤ α ≤ 100 °.

For this purpose, the adapter plate 20 has a bore for the mounting rod 15, which is arranged centered over the bore which is provided in the anti-rotation plate 16. In addition, the adapter plate 20 now carries the securing pin 17 which fixed the adapter plate 20. In addition, the adapter plate 20 has a releasable connecting element 25, which engages with the perforated scanning bead 18 or a slotted slot of the anti-rotation plate 16. The bore for such a releasable connecting element 25 rests on a circular portion with a radius r, which corresponds to the distance a between the mounting rod 15 and the securing pin 17. This geometric arrangement will be explained with the following figures 7 and 8.

Figure 7 shows a schematic view of the bottom 41 of an adapter plate 20. The adapter plate 20 has at least three holes 21, 22 and 24: a central bore 21 for the mounting rod and at a distance a to a bore 22 for the securing pin. On a circular line 23, which has a radius r, is at an angle o < _2, a further bore 24 in the adapter plate 20 spaced from the bore 22 is arranged. This further bore 24 receives the detachable connecting element 25 shown in FIG. The radius r of the circular line 23 corresponds to the distance a between the bore 21 and the bore 22. The further bore 24 is offset relative to the bore 22 by the angle c * ₂ with respect to the bore 21. Thus, the chuck 10, which is shown in Figure 6, can be offset by a total angle α = αi + 0C ₂ with respect to the longitudinal axis of the Andruckarms 11, wherein the total angle α can be preset and secured both right and left of the Andruckarm.

FIG. 8 shows a schematic side view of the adapter plate 20 according to FIG. 7. In the side view, the holes 21 and 22 are mounted one above the other with dashed lines and additionally the further bore 24 is shown. For this purpose, the bore 22 has a counterbore 40 for a countersunk screw for fastening the securing pin 17, which is shown in FIG. These Countersink 40 has the advantage that with a corresponding countersunk screw the bottom 41 of the adapter plate 20 remains flat after fixing the securing pin.

FIG. 9 shows a schematic perspective view of a clamping system 3 with a pressure device 7 of a third embodiment of the invention. The pressure device 7 according to FIG. 9 differs from the preceding embodiments in that a boom 26 is attached to the free end 13 of the pressure arm 11. For this purpose, the arm 26 on its end 13 of the Andruckarms 11 fixed end 27 next to the mounting rod 15 at a distance a the securing pin 17, which projects into the slot 14 of the Andruckarms 11. The free end 28 of the arm 26 carries on its underside the anti-rotation plate 16 with the clamping head 10. For this purpose, the boom 26 has a through hole 29 in which a second mounting rod 31 is disposed, and a further through hole 30 at a distance a to the first through hole 29th in which a second securing pin 32 is arranged, which holds the anti-rotation lock plate 16 in position. The securing pin 32 engages with a curved perforated grid bead 18 of the anti-rotation plate 16, whereby the position of the clamping head 10 is secured. The second securing pin 32 can also be fixed in a curved slot slot 19, as shown in FIG. 4.

FIG. 10 shows a schematic perspective view of the clamping system 3 with the pressing device 7 according to FIG. 9 with preset and secured angle α i between a jib 26 and a chuck 10. Components with the same functions as in the preceding figures are identified by the same reference numerals and are not discussed separately , To adjust the angle αi, only the securing pin 32 in the Through hole 30 in the slotted slot or in the hole grid bead 18 of the anti-rotation plate 16 offset fixed.

FIG. 11 schematically shows a side view in FIG. 11a and a front view in FIG. 11b of a cantilever 26. The length l of the cantilever 26 may vary, or different standardized lengths l of the cantilever 26 may be provided in a tool set, in order to provide as variable a tensioning system as possible to ensure. The boom 26 has at the end 27, which is fixed to the Andruckarm the pressure device, two holes 21 and 22, wherein the bore 21 is provided for attaching the mounting rod and the bore 22 for attaching the securing pin disposed in the boom 26 is. The bores on the free end 28, which is to carry the anti-rotation lock plate with the chuck, are adapted to the bores 21 and 22 with their diameters, wherein the bore 29 are provided for a second mounting rod and the bore 30 for a second securing pin. In this case, the second securing pin may have a smaller diameter than the first securing pin, so that the through holes 22 and 30 differ in diameter.

FIG. 12 shows a schematic perspective view of a clamping system 4 with a pressure device 8 of a fourth embodiment of the invention. This fourth embodiment of the invention differs from the third embodiment of the invention in that in addition to the boom 26 now also an adapter plate 20 is provided on the free end of the boom 26. With this adapter plate 20, as stated above, the angle α between the longitudinal extent of the Andruckarms 11 with boom 26 and the clamping head 10 can be further increased. Figure 13 shows a schematic plan view of a clamping system 1 to 4 with a pressure device 5 to 8 and the possible adjustable clamping range 39 of a clamping head of this pressure device 5 to 8. The clamping region 39 may for example comprise a length L of about 230 mm and a width b of about 100 mm. The length L of the clamping region 39 depends on the magnitudes of the boom and the anti-rotation plate with clamping head, and the width b of the clamping portion 39 depends on the pivot angle α, with the clamping head is pivoted about the mounting rod at the free end of a pressure device 4. Furthermore, the width b of the clamping region 39 is influenced by the magnitude of the anti-rotation plate with clamping head. For this purpose, the pivoting angle α can be mounted through the adapter plate, as explained above, to different embodiments of the pressure arm 11 with and without a cantilever.
