Definitions

  • the invention relates to a method for setting a blind rivet nut, in which the blind rivet nut is inserted into a hole of a component and compressed with a screwed-set pin to a blind rivet and in which the blind rivet nut in the state in which it is inserted into the hole with a Tolerance compensation element is in threaded engagement, which has a bore through which the setting bolt is push-through and which has a friction element.
  • Such blind rivet nuts with tolerance compensation element serve to connect two components with the help of an inserted into the blind rivet nut connecting bolt with each other.
  • the tolerance compensation element makes it possible to bridge the distance between the components to be connected and to compensate for any distance tolerances.
  • the connecting screw is screwed into the blind rivet nut
  • the friction element ensures that the tolerance compensation element is rotated and thereby screwed out of the blind rivet nut, so that it meets the other of the components to be joined.
  • the tolerance compensation element abuts against this component, the friction element slips through, and the two components with the tolerance compensation element inserted between them can be clamped together.
  • connection devices of this type has the problem that the setting bolt and the connecting screw are screwed one after the other into the same threaded bore of the blind rivet nut, but the friction element as possible only with

  • the blind rivet nut without tolerance compensation element is first fixed in one of the components to be connected, and only then is the tolerance compensation element screwed in.
  • a connecting device in which the friction element first assumes an inoperative position in which it does not interact with the setting bolt, and is transferred to an effective position only after the setting of the blind rivet nut.
  • This allows the tolerance compensation element to be screwed into the blind rivet nut before it is fixed in one of the two components.
  • the advantage is that the blind rivet nut with tolerance compensation element can be provided as a preassembled unit and thus the setting process can be carried out more efficiently.
  • the object of the invention is to provide further improved method for setting the blind rivet nut, in which in particular a higher tensile force can be exerted on the blind rivet nut to compress them to the blind rivet.
  • the strength of the blind rivet fastening can be increased or, given a given strength, the connecting device can be made more compact as a whole.
  • this problem is solved in that the tolerance compensation element is secured against screwing when screwing the setting bolt.
  • This rotation can be achieved for example by a corresponding design of the setting tool, in which the setting bolt is held rotatably drivable.
  • the setting tool has a support sleeve which is designed to exert an axial pressure on the tolerance compensation element when the set bolt is screwed in so that it is clamped to the blind rivet nut and / or the component connected thereto. When screwing the setting bolt thus slides through the friction element, so that the tolerance compensation element retains its position.
  • the tolerance compensation element can also be held by means of the support sleeve clamped in position, so that it retains its axial position even when unscrewing the setting bolt and, if it is already in an end position in the Blind rivet nut is also not tightened so tight that it can not be solved later.
  • the invention enables a shortening of the screwing length of the setting bolt into the blind rivet nut, in many cases this screwing length can be selected so short that it is smaller than the required adjustment path for the tolerance compensation element. In that case, according to another embodiment of the invention, it is possible to simply allow the tolerance compensating element to rotate when the setting bolt is screwed in, with the result that the tolerance compensating element unscrews out of the blind rivet nut by a certain distance.
  • the upsetting of the blind rivet nut leads to a corresponding displacement of the tolerance compensation element.
