Definitions

  • the invention relates to a device for fixing to at least one component, with a compensating element and a base element, the compensating element being connected to the base element via a screw connection.
  • the tolerance compensation elements have a first sleeve and a second sleeve which can be fixed on or in the first sleeve by means of a screw connection, the first sleeve and the second sleeve each having a passage, with a screw through the passages and through the Component can be screwed into a thread of a holding means.
  • a friction element is arranged in the passage of the second sleeve, which abuts the screw at least in sections.
  • the second sleeve When the screw is screwed into the thread of the holding means, the second sleeve is also rotated due to the friction element that connects the screw and the second sleeve. Due to the opposite direction of rotation of the screw connection and the thread of the holding means, the second sleeve is unscrewed from the first sleeve when the screw is screwed in.
  • this construction enables tolerance compensation when fixing two components, the distance between which is not clearly determined.
  • Corresponding devices are known for example from FR 2 792 039 B1 and DE 100 34 968 A1.
  • the present invention is therefore based on the object of specifying a device for fixing to at least one component, which at least enables the compensation of small tolerances with simple means.
  • the above object is achieved by the features of claim 1.
  • the device in question is characterized in that an engagement area for an actuating tool is arranged on and / or in the compensating element in order to twist the compensating element relative to the base element.
  • both a friction element and different directions of rotation of the screw connection of the base element and of the compensating element and of a holding means that may be provided are not absolutely necessary in order to compensate for at least small tolerances.
  • the compensating element can be rotated relative to the base element using an actuating tool.
  • the compensating element can thus be screwed into or out of the basic element, so that the length of the device can be adapted to the installation situation.
  • an engagement area for an actuating tool is arranged on and / or in the compensating element.
  • the compensating element can thus be adapted in a simple manner with respect to the basic element. Coupling with a screw to be inserted into the device is no longer necessary.
  • actuating tool is to be understood as any tool that has an effective area that corresponds to the area of action, so that the compensating element can be unscrewed from the base element or screwed into it.
  • the operating tool is not part of the claimed device.
  • the area of attack can be designed as a hexagon socket, hexagon socket hexagon, square socket etc. Any construction that enables the compensating element to be rotated relative to the base element via an actuating tool can be implemented here.
  • a torque of at least 2 Nm, in particular of at least 3 Nm, preferably of at least 4 Nm, may be necessary to loosen the screw connection.
  • the compensating element can be screwed into the base element over a defined area in order to achieve a desired overall length of the device.
  • the device can be delivered to the user. If the total length of the device has to be adjusted, for example to compensate for small tolerances between the distances between two components, the compensating element can be rotated out of the base element or rotated into the base element with an actuating tool.
  • these can each have at least one thread. Furthermore, it is conceivable that the base element and the compensating element have a plurality of threads that correspond to one another.
  • the at least one thread of the base element and the at least one thread of the compensating element can be designed such that they do not correspond exactly to one another. This makes it possible to set a specific thread clamping, which in turn can achieve a defined torque for loosening the screw connection. In a further advantageous manner, this can be at least 2 Nm, in particular at least 3 Nm, preferably at least 4 Nm.
  • the base element and / or the compensation element consist of a metal, in particular steel, or of a plastic.
  • a stop ring could be provided on the compensating element, whereby this can also consist of steel or a plastic.
  • the Stop ring could have a through opening with a diameter of 6 mm to 8 mm, preferably 6.5 mm to 7.5 mm, in particular 7.2 mm.
  • a holding means with a thread could be arranged such that a screw can be screwed into the thread through the compensating element and the base element.
  • the holding means could be arranged on a clamp which is connected to the base element and / or the holding element.
  • the clamp could, for example, be fixed to a first component, so that the compensating element, in particular with a stop ring, bears against a second component.
  • An opening in the first component could be used to screw a screw through the compensating element and the base element and through an opening in the second component into the holding means in order to connect the components to one another.
  • the holding means can be realized, for example, as a mother.
  • the holding means could be realized as a one-piece thread with the clamp.
  • the screw connection between compensating element and base element and the screw connection between the thread of the holding means and the screw could have the same direction of rotation. It is pointed out that part of the disclosure is also a set consisting of a device according to the invention and a screw and / or an actuating tool.
  • a thread adhesive could be applied to the screw connection of the compensation element and the base element.
  • the torque that must be present to loosen the screw connection can also be set using the thread adhesive.
  • the attack area could be formed in one piece with the compensation element.
  • the compensating element could be made of metal, in particular as a turned part, wherein the engagement area can be milled into the compensating element.
  • the equalizing element could be made of plastic. This would enable production using injection molding or 3D printing.
  • the area of attack could be formed on an insert.
  • the insert could be positively and / or non-positively and / or cohesively connected to the compensating element.
  • the insert could consist of a metal or a plastic. In a further advantageous manner, this could be a tough plastic, for example polyoxymethylene (POM).
  • POM polyoxymethylene
  • the insert could be designed in the form of a sleeve, the inner wall of the sleeve serving as an engagement area, for example, as an inner hexagon.
  • sleeve-shaped is to be understood broadly, including any essentially cylindrical geometry.
  • recesses could be formed on the outer wall of the insert. This makes it possible to press the insert into the compensating element, excess material of the insert being able to be pressed into the recesses. This constructive measure prevents the geometry of the attack area from being changed.
  • the insert could have grooves and / or lugs on its outer wall, which engage in grooves and / or lugs of the compensating element.
  • the grooves could extend essentially in the longitudinal direction of the insert. With correspondingly corresponding grooves and / or lugs on the compensating element, the insert is ideally secured against slipping in the circumferential direction.
  • Fig. 2 shows a schematic, sectional representation of an embodiment example of a device according to the invention.
  • Fig. 3 shows a schematic, sectional representation of an embodiment example of a device according to the invention.
  • Fig. 1 shows a first embodiment of a device according to the invention.
  • the device has a compensating element 1 and a base element 2.
  • the compensating element 1 and the base element 2 each have a thread 3 in order to realize a screw connection.
  • the screw connection is specifically designed to be stiff, so that a torque of at least 2 Nm, in particular of at least 3 Nm, preferably of at least 4 Nm, has to be applied in order to rotate the compensating element 1 relative to the base element 2.
  • a thread adhesive can be applied to one of the threads 3.
  • the threads 3 of the compensating element 1 and the base element 2 can be designed such that they do not exactly match each other. This allows a threaded clamp to be set, so that a rotation of the compensating element is only possible at the desired torque.
  • an engagement area 4 for an actuating tool is provided on the compensating element 1.
  • the attack area 4 is realized as a hexagon socket.
  • the attack area 4 is formed on an insert 5, which is pressed into the passage of the base element 1, so that a positive connection is established.
  • the insert 5 is sleeve-shaped in the broadest sense, the area of attack 4 on the inner wall of the Insert 5 is arranged.
  • the outer wall of the insert 5 has cutouts 6. These serve to ensure that the material of the insert 5 can escape into the cutouts 6 when the insert 5 is pressed into the compensating element 1.
  • the compensating element 1 consists of a metal, in particular a steel
  • the insert 5 consists of a, preferably tough, plastic.
  • a stop ring 7 is provided on the compensating element 1.
  • the device further comprises a clip 8, on which a holding means 9, for example a nut, is formed with a thread 10.
  • the device can be fixed with the clamp 8, for example, on a first component in such a way that the stop ring 7 bears against a second component.
  • a screw not shown, can then be screwed into the passage of the compensating element 1 via a recess in the second component and into the thread 10 of the holding means 9 through a recess in the first component.
  • the compensating element 1 can be turned into or out of the base element 2 with an actuating tool acting on the engagement area 4.
  • FIG. 2 another embodiment of a device according to the invention is shown.
  • lugs 11 are formed on the outer wall of the insert, which lugs engage in grooves 12 of the compensating element 1.
  • a positive connection between the compensating element 1 and the insert 5 is realized in the circumferential direction, so that the insert 5 does not rotate with respect to the compensating element 1 when a torque is exerted via the actuating tool.
  • 1 lugs are provided on the compensating element and 5 grooves on the insert. Since the device according to FIG. 2 otherwise corresponds to the device shown in FIG. 1, reference is made to the description of the figures above.
  • the compensating element 1 is preferably made of a metal, in particular steel.
  • the compensating element 1 could be realized as a turned part, the engagement area 4 being produced, for example, by milling.
  • Such a construction is characterized in that the device is extremely robust.
  • the compensating element 1 is made from a material other than metal, in particular from plastic. With such a configuration, the compensating element 1 can be manufactured extremely simply, for example by injection molding or 3D printing. To avoid repetition, reference is also made to the description of FIGS. 1 and 2, which applies analogously to FIG. 3.
