Definitions

  • the present invention relates to a press-in nut according to the preamble of patent claim 1.
  • Press-in nuts of this type are known.
  • Such a press-in nut is described, for example, in DE-OS 19 58 353, wherein on one side of the nut there is provided a toothed collar which tapers outwards in a conical shape and whose largest diameter is smaller than the diameter of the nut.
  • a groove is provided between the collar and the nut in the region of the circumference of the collar.
  • a disadvantage of such a press-in nut is that it is difficult to assemble due to the wedge-shaped design of the collar, since there is no smooth or flat contact surface.
  • the press-in nuts inserted into the bores of workpieces during preassembly are therefore rotated or tilted in each case by different angles with respect to the vertical. For this reason, the pre-assembled press-in nuts do not assume a defined position in relation to the tools that attack them during further processing.
  • the object of the present invention is to provide a press nut which is designed so that it
  • O PI assumes a precisely defined position after insertion into a borehole.
  • a major advantage of the press-in nut according to the invention is that it can be inserted into the bores of workpieces in an extremely simple manner in such a way that it automatically assumes a precisely defined position.
  • the press-in nut according to the invention advantageously has a high torsional strength with respect to its longitudinal axis.
  • the nut is able to withstand forces acting on it in the axial direction.
  • Another advantage of the present invention is that nuts inserted into the bores of a workpiece during preassembly retain their defined position even with relatively violent movements of the workpiece.
  • the press nut is automatically centered with respect to the borehole during insertion.
  • a press-in nut 1 essentially consists of a head part 2 and a collar 3 arranged on one side of the head part 2.
  • the collar 3 is preferably of circular cylindrical shape on its circumference that it can be used with a slight play in the bore 6 of a workpiece 5 (Fig. 2).
  • the collar 3 is spaced from the head by an annular web 4 and has a diameter that is smaller than the diameter of the head 2.
  • the diameter of the annular web 4 is smaller than the diameter of the collar 3.
  • a groove 13 is formed between the surface 12 of the head 2 facing the collar 3 and the surface of the collar 3 facing the head 2 in the region of the circumference of the collar.
  • the internally threaded bore of the nut 1 is designated 8.
  • teeth 7 are preferably attached to the nut shown in FIG. 1 by means of a knurling process at the lower end of its peripheral surface facing the collar 3.
  • material is displaced from the lower circumferential area of the head 2 of the nut such that the teeth 7 in the direction of the longitudinal axis protrude from the nut 1 over the lower end face 12 of the head 2 in the direction of the collar 3, whereby an undercut 15 is formed.
  • a collar can also be provided, the circumferential surface of which is designed in such a way that it only engages in partial areas on the inner wall of the bore 6 in such a way that a central guidance of the collar in the borehole is guaranteed.
  • 2b shows a collar, for example, which engages in three partial areas on the inner wall of the bore 6.
  • 2c shows, as a further example, a cross section of a collar in which a part of the cross section is cut away by a chord.
  • FIG. 5 shows a further embodiment 21 of the press-in nut according to the invention, in which the head part is polygonal.
  • the head part 21 corresponds to a hexagon nut.
  • the serrated areas which arise during the knurling process and which arise mainly in the vicinity of the edges are designated by 23 in FIG.
  • the advantage of this embodiment 21 of the invention is that the torsional strength of the press nut due to its polygonal or hexagonal design compared to the previously described press nut with the circular cylindrical shape of the head is significantly increased if the press nut 21 when screwing a screw into the material of the workpiece is drawn in. This is because the edges 24 penetrating into the workpiece then contribute to increasing the torsional strength in addition to the teeth 23.
  • FIG. 6 shows a further embodiment of the invention, in which the press nut shown in FIG. 2 is additionally provided on the collar 31 with teeth 16, which are also preferably produced by a knurling process.
  • the collar 31 is conical in such a way that it tapers towards the end facing away from the head 2.
  • the teeth 16 have the effect that when the F-collar 31 is pressed in material pushed to the side and upwards is pressed against the end face 12 of the head 2 and from there again in the radial direction inwards into the groove 3.
  • the teeth 7 act in the manner already described above.
  • FIG. 7 shows a press nut 22 which is designed in accordance with the press nut 21 shown in FIG. 5, but the collar 31 is designed in the manner already described in connection with FIG. 6.
  • additional lugs 32 can be provided on the collar 31. 6 and 7 such possible approaches 32 are shown by broken lines. These approaches, which can be designed as already described in connection with the collar 3 of FIGS. 1 to 5, enable the press nut shown in FIGS. 6 and 7 to be automatically aligned in the borehole, for example when Pre-assembly process.
  • the teeth 7, 16 and 23, which are preferably produced by knurling, can also be designed such that they run obliquely to the longitudinal axis. It is also conceivable to produce the teeth 7 and 23 and the teeth 16 in the embodiments of FIGS. 6 and 7 in such a way that they run obliquely to the longitudinal axis of the nut and in opposite directions. In these embodiments, the teeth 7 or 23 or the teeth 16 can also run obliquely to the longitudinal axis and the teeth 16 or the teeth 7 or 23 can run parallel to the longitudinal axis.

Abstract

L'ecrou encastrable (1) presente des dents (7) sur le pourtour de la tete (2) sur la face frontale (12) qui est fixee a la paroi. Les dents (7) sont fabriquees de maniere telle que leurs extremites depassent de la face frontale (12) dans la direction d'une collerette (3), qui est separee de la face frontale (12) par une rainure (4). La collerette est au moins en partie cylindrique sur son pourtour. Les pointes des dents (7) se trouvent en direction radiale depuis l'axe de l'ecrou encastrable (1) au dela du pourtour de la collerette (4). Cet ecrou encastrable prend automatiquement une position definie juste apres son installation dans un trou. Ces ecrous encastrables seront notamment employes pour etre fixes aux extremites d'alesages prevus dans des plaques ou analogues.
