Description

The invention relates to a device for securing at least one component, in particular at least one compressor. The invention further relates to a test setup with such a device and a method for securing the component.

It is known to mount certain components, such as air compressors or parts of air supply systems, on fixtures. This enables, for example, testing, analysis, or transport of these components. It is also known to mount components, such as workpieces, for machining using fixtures. Such fixtures then form, for example, part of a welding table for a welded part or part of a processing machine, such as a machining machine, for a workpiece to be machined.

Due to the multitude of different geometric dimensions and shapes of such components, it is often necessary to develop and manufacture a fixture adapted to the respective component. Depending on the component to be fixed or tested, different requirements must also be taken into account, for example, regarding the robustness of the components against vibrations.

To ensure secure fixation, it is also necessary to test the functionality of individually developed devices and to obtain approval for these devices.

Particularly in the case of small quantities of components to be fixed or tested, the individual development, production and approval of the respective device leads to a not insignificant share of the effort in the overall development of the respective component.

An object of the present invention is to at least partially overcome the aforementioned disadvantages.

One object underlying the present invention is to provide a device capable of securing a variety of different components. Another object of the invention is to provide a device that can be easily and flexibly adapted to each component to be secured.

• mindestens ein eine längliche Aufnahmeöffnung aufweisendes Basiselement, wobei das Basiselement an einer Innenwand der länglichen Aufnahmeöffnung eine Nut aufweist,
• mindestens eine Spanneinheit mit einem Spannmodul und einem Sockel, wobei der Sockel ein in die Nut eingreifendes Gleitelement umfasst,
• wobei das Spannmodul verstellbar ist zwischen einem gelösten Zustand und einem gespannten Zustand, wobei in dem gelösten Zustand die Spanneinheit gegenüber dem Basiselement beweglich und durch das Gleitelement in der Nut geführt ist,
• wobei in dem gespannten Zustand das Spannmodul eine Spannkraft auf die Komponente ausübt und das in die Nut eingreifende Gleitelement die Spanneinheit durch Selbsthemmung an dem Basiselement fixiert.

According to the invention, this object is achieved by a device for fixing at least one component, in particular at least one compressor, the device comprising:

• at least one base element having an elongated receiving opening, wherein the base element has a groove on an inner wall of the elongated receiving opening,
• at least one clamping unit with a clamping module and a base, wherein the base comprises a sliding element engaging in the groove,
• wherein the clamping module is adjustable between a released state and a clamped state, wherein in the released state the clamping unit is movable relative to the base element and is guided in the groove by the sliding element,
• wherein in the clamped state the clamping module exerts a clamping force on the component and the sliding element engaging in the groove fixes the clamping unit to the base element by self-locking.

The device according to the invention can be used to fasten a large number of different components, whereby the device can be easily and flexibly adapted to the respective component, in particular without the need for renewed approval or functional testing of the device. The clamping unit guided in the groove makes it possible to quickly and easily adapt the device to the dimensions of a specific component and to fix it in place. Time-consuming individual solutions in the areas of design, production and approval are therefore no longer necessary. Complicated conversions of fastening structures are also no longer necessary, since the clamping module can be easily positioned in the released state and the component can be fixed by adjusting the clamping module to the clamped state.

The 1 to 4 show a part of a test setup 2, for example a test carriage, according to a first embodiment. The test setup 2 comprises a device 4 for fixing at least one component. In 4 A component part 5 of the component is shown as an example. The component part 5 is, for example, a foot of the component, which is fixed by the device 4.

The component is, for example, a part or a machine. Preferably, the component is an (air) compressor. In particular, the (air) compressor is configured to provide air pressure for a pneumatic system of a rail vehicle or a commercial vehicle. Test setup 2 serves, for example, to test the functionality of the (air) compressor.

According to another example, the component is a weldment or comprises one or more parts to be welded. In this case, the device 2 forms part of a welding table on which parts are attached or fixed prior to a welding operation.

The device 4 comprises a base element 6 and at least one clamping unit 8 for clamping or fixing the at least one component. In particular, the base element 6 holds or accommodates the clamping unit 8.

The base element 6 itself rests, for example, on rails 9 and/or is attached to them, preferably displaceably. The base element 6 forms, for example, a table top, which is held by the rails 9 and/or other supporting elements not shown.

The base element 6 has at least one elongated receiving opening 10. The elongated receiving opening 10 forms, in particular, an elongated hole. The base element 6 has a groove 14 on an inner wall 12 of the elongated receiving opening 10. The inner wall 12 preferably extends at right angles to an upper side of the base element 6, which is arranged to support the component. The upper side forms, in particular, a table surface. The elongated receiving opening 10 preferably comprises an enlargement 11, which is arranged, in particular, for inserting a part of the clamping unit 8 into the elongated receiving opening 10. The enlargement 11 is arranged, for example, at one end of the elongated receiving opening 10.

The at least one clamping unit 8 comprises a clamping module 16 and a base 18, wherein the base 18 comprises at least one sliding element 20 engaging in the groove 14, for example a disc or a ring.

Preferably, the sliding element 20 has a diameter that is greater than a minimum distance between two opposing surfaces of the inner wall 12 and that is less than a diameter of the enlargement 11. This makes it possible to insert the sliding element 20 into the enlargement 11 of the elongated receiving opening 10 and then insert it into the groove 14 or slide it in the groove 14.

The clamping module 16 is adjustable between a released state (not shown) and a clamped state. In the released state, the clamping unit 8 is movable relative to the base element 6 and guided in the groove 14 by the sliding element 20. In the released state, the clamping unit 8 is therefore displaceable and/or rotatable, in particular relative to the base element 6. In the clamped state, the clamping module 16 exerts a clamping force on the component, in particular on the component part 5. In particular, the clamping force causes the component to be clamped between the clamping module 16 and the base element 6.

The sliding element 20 engaging in the groove 14 fixes the clamping unit 8 to the base element 6 in the clamped state by self-locking.

"Self-locking" or "self-locking" is understood in particular to mean that a fixation between two elements occurs through frictional resistance, here at least between the clamping unit 8 and the base element 6. Preferably, the self-locking prevents displacement and/or rotation. In particular, it prevents the clamping unit 8 with the clamping module 16 from shifting and/or rotating relative to the base element 6 under a given force acting on it.

Preferably, the clamping module 16 exerts the clamping force on the component, so that in response, the sliding element 20 engaging in the groove 14 fixes the clamping unit 8 to the base element 6 by self-locking. The self-locking is generated in particular by a (partial) counterforce or (partial) reaction force of the clamping force.

In particular, the clamping unit 8 fixes itself or inhibits itself by jamming or tilting in the groove 14. For this purpose, in particular a (partial) counterforce of the clamping force and/or a (partial) counter-torque of the clamping force acts via the sliding element 20 on surfaces of the groove 14, so that self-locking of the clamping unit 8 takes place in a given position and orientation relative to the base element 6.

According to one example, the self-locking action is at least partially generated by a force acting between an upper side of the sliding element 20 and a surface of the groove 14 in contact with this upper side. This force acts, in particular, substantially perpendicular to the upper side of the sliding element 20. This force is also preferably a reaction force of the clamping force.

The clamping module 16 is, for example, a clamping lever. According to another example, the clamping module is a clamping wheel.

The clamping module 16 is, for example, a toggle clamp. An example of the toggle clamp is shown in the 1 to 4 illustrated. The clamping module 16 comprises, for example, a first arm 22 and a second arm 24, which are connected to one another by a common first rotation axis 26. The clamping module 16 further comprises a base 27, which receives a second rotation axis 28 and a third rotation axis 30. The second rotation axis 28 forms a rotatable connection of the first arm 22 to the base 27. The third rotation axis 30 forms a rotatable connection of a transmission element 32 to the base 27. The transmission element 32 also receives a fourth rotation axis 34, which forms a rotatable connection of the transmission element 32 to the second arm 24. The transmission element 32 maintains a constant distance between the third rotational axis 30 and the fourth rotational axis 34. The first, second, third and fourth rotational axes 26, 28, 30, 34 preferably extend parallel to one another in each state of the clamping module 16, ie in particular in the released state, in the clamped state and in intermediate states between the released and the clamped state.

In the released state of the clamping module 16 (not shown), the first arm 22 and the second arm 24 extend at an angle to one another. In particular, in the released state, the arms 22, 24 each extend obliquely upward from the first rotation axis 26 and/or form a V.

By simultaneously rotating all axes 26, 28, 30, 34, the clamping module 16 can be transferred from the released to the clamped state. In the clamped state, as can be seen in 4 , the first rotation axis 26, the fourth rotation axis 34, and the third rotation axis 30 extend parallel to one another and are intersected by a common straight line 36. In particular, the clamping module 16, e.g., the clamping lever, is in a self-locking position in the clamped state.

The clamping module 16 comprises, for example, a handle 40 at a first end 38. The handle 40 forms, in particular, one end of the second arm 24. The handle 40 serves, in particular, to adjust the clamping module 16 from the released to the clamped state by manual actuation. According to examples, the handle 40 further serves to position the clamping unit 8 relative to the base element 6 or to position the base element 6 itself, as explained further below by way of example.

The clamping module 16 also comprises, for example, at a second end 42 opposite the first end 38, a clamping punch 44 which is suitable or configured to transmit the clamping force to the component. In the clamped state, the clamping punch 44 is in particular in contact with the component part 5, as shown by way of example in 4 illustrated. The clamping die 44 is made of an elastomer or rubber, for example.

According to one example, the clamping module 16 further comprises a shaft 46 supporting the clamping punch 44. The shaft 46 is attached to the first arm 22 of the clamping module 16, in particular detachably attached, for example by a screw connection. The shaft 46 is displaceable, for example, along and/or perpendicular to a longitudinal direction of the first arm 22. Thus, a position and/or height of the pressure punch 44 can be adjusted.

According to one example, the clamping module 16 also includes an adapter at the second end 42, which supports the clamping punch 44 and aligns it in a predetermined direction. This predetermined direction, in particular, forms an angle other than 90 degrees with an axis of the first arm 22. Thus, additional gripping positions or angles for fastening the component are achieved, since, in particular, the pressure punch 44 can exert a force on the component in an adapted direction.

The base 18 is preferably detachably connected to the base of the clamping module 16 via a screw connection 47.

In addition to the sliding element 20, the base 18 comprises, for example, a threaded rod 48 with an external thread (not shown), wherein the sliding element 20 is screwed onto the threaded rod. The base 18 further preferably comprises a head 50, which is, for example, circular. The head 50 is, for example, glued or welded to the threaded rod 48. According to another example, the head 50 and the threaded rod 48 are manufactured as a single piece. The threaded rod 48 extends through the elongated receiving opening 10, and the head 50 rests, for example, on the base element 6, so that, in particular, slipping of the threaded rod 48 through the elongated receiving opening 10 is prevented. According to examples, the base 18 also comprises one or more lock nuts 52 screwed onto the threaded rod 48 and/or one or more washers (not shown).

Preferably, a distance between the base element 6, in particular a turntable 56, and the clamping module 16 is adjustable by rotating the sliding element 20 on the threaded rod 48. For example, it is possible to flexibly adapt a position of the clamping module 16 above the base element 6, in particular a position of the clamping die 44 above the base element 6, to a height of the component to be fastened.

The base element 6 comprises according to the first embodiment, particularly shown in the 1 to 6 , a turntable 56 having the elongated receiving opening 10, and a receiving plate 58 receiving the turntable 56. The turntable 56 is movable, in particular rotatable, relative to the receiving plate 58, preferably only in the released state. In the tensioned state of the clamping module 16, however, the turntable 56 is self-lockingly fixed relative to the receiving plate 58. By "the turntable is self-lockingly fixed relative to the receiving plate" is meant in particular that a fixation between the turntable 56 and the receiving plate 58 occurs due to frictional resistance, for example by jamming or tilting.

Preferably, the self-locking mechanism prevents displacement and/or rotation. In particular, it prevents the rotating disk 56 from shifting (e.g., partially lifting off) and/or rotating relative to the support plate 58 when a given force is applied to the rotating disk 56.

In particular, according to the first embodiment, the clamping unit 8, in the released state, is movable relative to the rotating disk 56, which is guided in the receiving plate 58. In the clamped state, the clamping unit 8 is fixed to the rotating disk 56 by self-locking. Furthermore, according to this example, the rotating disk 56 is fixed to the receiving plate 58 by self-locking in the clamped state.

An exemplary individual view of the turntable 56 is shown in 5 The turntable 56 preferably has a first outer edge 60 and a second outer edge 62 running concentrically and parallel to the first outer edge 60. Both outer edges 60, 62 define a circular shape of the turntable 56, wherein, for example, the radius of a circle defined by the first outer edge 60 is greater than the radius of a circle defined by the second outer edge 62. The first outer edge 60 is preferably connected to the second outer edge 62 via a step 64. The step 64 extends, for example, at right angles to the outer edges 60, 62 and preferably over the entire circumference of the turntable 56.

An exemplary individual view of the mounting plate 58 is shown in 6 shown. The receiving plate 58 has a circular opening 66 for receiving the turntable 56. In particular, the receiving plate 58 has a first inner edge 68 and a second inner edge 70 concentric with the first inner edge 68, the first and second inner edges 68, 70 being connected by a step 72.

In the 1 to 4 The turntable 56 is received by the receiving plate 58. In particular, the step 64 of the turntable 56 rests on the step 72 of the receiving plate 58. The first outer edge 60 faces the first inner edge 68, and the second outer edge 62 faces the second inner edge 70.

Preferably, in the released state of the clamping module 16, a radial distance between the first outer edge 60 and the first inner edge 68 is greater than a radial distance between the second outer edge 62 and the second inner edge 70. This results in the self-locking in the clamped state of the clamping module 16 being achieved by jamming or oblique contact between the second outer edge 62 and the second inner edge 70. Preferably, the second outer edge 62 and the second inner edge 70 have mechanically smoothed surfaces, whereas the surface(s) of the first outer edge 60 and/or the first inner edge 68 have a greater roughness than the former surfaces. This makes it possible to provide a small distance between the second outer edge 62 and the second inner edge 70, so that even a slight tilting of the turntable 56 in the clamped state of the clamping module 16 leads to self-locking.

As particularly in 3 As can be seen, the device 4 comprises, for example, a plurality of securing elements 74 fastened to a side of the turntable 56 or the receiving plate 58 facing away from the clamping module 16. These are fastened in particular to an underside of the base element 6 or an underside of the receiving plate 58. The securing elements 74 are arranged or configured to secure the turntable 56 in the receiving plate 58. The securing elements 74 preferably have an elongated base body. For example, the securing elements 74 are holding claws. According to other examples, the device 4 does not have any such securing elements. In particular, the inventors have shown that self-locking of the turntable 56 relative to the receiving plate 58 in the clamped state also occurs without the securing element.

According to one example, the device 5 further comprises at least one based on the element 6 arranged insulation mat 76. This is particularly designed to dampen vibrations between the component and the base element 6.

A second embodiment of the device 4 will now be described with regard to the 7 described. The device 4 according to the second embodiment includes some, several, or all of the features of the first embodiment, except for the differences described below. The same reference numerals are used for the same or corresponding elements as in the first embodiment.

In contrast to the first embodiment, the base element 6 does not comprise a rotary disk which is accommodated in a receiving plate, but the elongated receiving opening 10 is provided in a plate which forms the base element 6. Here too, the clamping unit 8 is displaceable in the elongated receiving opening 10 in the released state and in the clamped state fixes the sliding element 20 engaging in the groove 14 (not visible in 7 ) the clamping unit 8 is self-locking on the base element 6.

According to further embodiments, the device 4 comprises at least n clamping units 8 and has at least n elongated receiving openings 10, where n is a natural number greater than or equal to 2, preferably greater than or equal to 4. According to examples, the device 4 comprises at least one clamping unit 8 arranged in a base element 6 according to the first embodiment, i.e. in a base element 6 with a turntable 56 and a receiving plate 58, as well as at least one further clamping unit 8 arranged in a base element 6 according to the second embodiment.

A method for fixing the component, which is, for example, a compressor, will now be described. The method is carried out by means of the device 4. It comprises at least one positioning step and a fixing step, which in particular follows the positioning step.

During the positioning step, the clamping module 16 is in the released state and the component is positioned on the at least one base element. In addition, the clamping module 16 is, for example, displaced along the groove 14. According to one example, the turntable 56, if present, is aligned or rotated relative to the receiving plate 58, for example by applying force via the handle 40, in order to achieve a positioning of the clamping module 16 that enables the component to be fixed. The positioning of the clamping module 16 is preferably achieved both by displacing it along the groove 14 in the elongated receiving opening 10 and by rotating the turntable 56. The alignment/positioning depends in particular on the positioning of adjustable feet of the component, in particular the component part 5. The receiving plate 58 can, for example, also be used as a support surface for objects to be tested, i.e., the component.

According to one example, the positioning step includes checking whether the height adjustment of the shaft 46 and/or the threaded rod 48 is desired/necessary for sufficient fixation of the component. The height of a fastening point of the component to be fixed, i.e., the height of the component part 5, is decisive for the height adjustment. For example, the positioning step includes adjusting the position or height of the shaft 46 and/or the threaded rod 48. The check and/or, if necessary, adjustment can also be performed during the fixation step.

The method for fixing comprises, for example, approaching the clamping module 16 to the fastening point of the component and finely aligning the clamping module 16, in particular after adjusting the position or height of the shaft 46 and/or the threaded rod 48.

During the fixing step, the clamping module 16 is moved from the released state to the clamped state. The clamping module 16 exerts the clamping force on the component. The sliding element 20 engaging in the groove 14 self-lockingly fixes the clamping unit 16 to the base element 6. If the device 4 includes the rotating disk 56, this is self-lockingly fixed relative to the mounting plate 58.

Thus, by applying the clamping force, both the component is fixed and - through corresponding counterforces - the clamping unit 8 is fixed by self-locking, as well as the turntable 56 if necessary.

Preferably, the fixing step consists of a single movement of the or each clamping module 16 to fix the component. This enables particularly simple and rapid fixing of the component with the device 4.

For example, the only movement of the or each clamping module 16 comprises depressing the handle 40 to a predefined clamping force.
