Definitions

  • the invention relates to a heald frame with releasable corner connections between the side supports and the shaft rods consisting of hollow profiles, in the cavity of which a projection connected to a side support engages in a pin-like manner and clamped by means of a screw, and with elastic vibration damping material in the corner connections for a relative mobility of each corner connection Side support and shaft rod under high loads.
  • the vibration damping element is arranged in the interior of the projection and is supported inwards against two screw bolts or rivet bolts penetrating the shaft rod.
  • a separate projection which is fastened with the aid of two screws extending through the side support, must be removed by loosening these screws, or in another embodiment there is a projection connected integrally to the side support and this to loosen bolts with a conical head and nuts, which extend through the shaft rod and have the form of detachable rents, these small special screws being easily lost.
  • a simple clamping screw cannot be used in this construction for fixing the pre-tension in the shaft rod, as in the known corner connections mentioned first. In weaving operations, however, it is of primary importance that the heald frame can be dismantled quickly and easily.
  • the present invention was therefore based on the object of using only one clamping screw for the corner connection between the side support and shaft rod of a heald frame, with which the projection of the side support can be clamped in the recess provided in the shaft rod. Furthermore, the task was not to use the vibration damping elements themselves for clamping the projection and furthermore the damping elements should be arranged so that they cannot be lost.
  • the heald frame has the features according to claim 1.
  • the projection consists of two rigid bodies separated from one another by at least one elastic vibration damping element, one of which is rigidly connected to the side support.
  • the other part is formed in two parts and one part passes through the body rigidly connected to the side support, the vibration damping element being located in between, and is firmly connected to another part, for example riveted, which part encloses the body rigidly connected to the side support with play on the outside , for example as a sheet metal shell, which forms the outer skin of the projection and can be clamped by means of a clamping screw.
  • the side support 1 shown in FIG. 1 with its upper end has a projection 2 on one narrow side, with the aid of which one of the corner connections of a heald frame is produced.
  • the projection arranged on the side support 1 projects into the cavity 3 of a shaft rod 4 of the heald frame and is clamped in the shaft rod with a clamping screw 5 which is passed obliquely through the shaft rod 4.
  • the exemplary embodiments shown in the figures differ in the design of the projection, which according to the invention consists of two rigid bodies separated from one another by at least one vibration damping element, one of which is connected to the rigid side support and the other of which is designed as a hollow profile for clamping Shaft rod serves.
  • the body 7 rigidly connected to the side support 1 is a flat rectangular frame which is formed in one piece with the side support, and furthermore the part serving to clamp the projection is constructed in several parts in all embodiments and exists in the embodiment according to FIG 1 and 2 from a metallic part 8 which penetrates the frame 7 transversely and which is separated from the frame 7 by a vibration damping element 9 which fills the space between them, and which part 8 also has a part 10 in the form which surrounds the frame 7 with play a U-shaped sheet metal sleeve is firmly connected.
  • This connection is carried out in the embodiment according to FIGS. 1 and 2 with the aid of three rents 11, through which the part 8 is firmly connected to the sheet metal casing 10.
  • Fig. 1 shows a section along the line 2-2 in Fig. 2, wherein the slightly stepped strip 12 for insertion into the sheet metal casing 10 is cut in its upper portion.
  • the body 7a rigidly connected to the side support 1 is not designed as a closed rectangular frame, but rather in a U-shape, so that the vibration damping element 9 can be pushed into the body 7a from the open side opposite the side support 1.
  • a bar 7b forming the fourth side of the frame is then screwed to the U-shaped body 7a by means of screws 7c.
  • the vibration damping element 9 can also be preloaded in order to influence the extent of the damping.
  • this design variant offers the possibility of replacing the vibration damping element connected to the outer sheet metal casing 10 if damage necessitates this, or if one wants to replace one vibration damping element with another with different damping properties.
  • All other embodiments differ only in the number of existing elastic vibration damping elements and in the adapted shape of the body rigidly connected to the side support and the part passing through it, which is firmly connected to the sheet metal casing and together with this forms the body serving for clamping .
  • the projection 2a consists of a slightly larger frame 7a, which is rigidly connected to the side support 1, and also of a rectangular through the frame 7a and arranged in the frame placed over corners Disk body 8a, which bears against four triangular vibration damping elements 9a, which have rounded corners and fill the triangular spaces between the frame 7a and the disk body 8a.
  • the vibration damping elements 9a also enclose a narrow tire 14 on the outside, which is present in all embodiments.
  • the disk body 8a is riveted to a U-shaped sheet metal sleeve 10a, which surrounds the frame 7a with play and contains a riveted strip 12 at the top in order to be able to clamp the projection 2a.
  • a further modified embodiment according to FIGS. 7-13 differs only in that, in this projection 2b, the disc body 8b passing through the same frame 7b is star-shaped and is in contact with four circular disc-shaped vibration damping elements 9b which fill the spaces in the corners of the frame.
  • FIG. 8 shows the unit to be inserted into the frame 7b and consisting of the disk body 8b and the vibration damping elements 9b and provided with a tire 14 on the outside, which is shown in a side view in FIG. 10.
  • 11 shows a view of the narrow side of the projection 2b arranged on the side support 1.
  • 12 shows a top view from above with the sheet metal casing 10b enclosing the frame 7b with play, while in the top view from above according to FIG. 13 only the side support 1 is shown with the frame 7b integrally connected to it.
  • FIG. 4 Two other embodiments are in the figures 4, 5 and 6 shown, which also differ only in the number of vibration damping elements present.
  • the flat rectangular body 7c rigidly connected to the side support 1 has cylindrical bores 17 passing through it.
  • the part passing through the body 7c here consists of a number corresponding to the number of bores present, of smaller in diameter and concentrically arranged in the bores cylindrical bolts 8c, each of which bears against the intermediate annular vibration damping elements 9c.
  • FIG. 4 there are two and in the embodiment according to FIG. 5 there are four ring-shaped vibration damping elements 9c.
  • the bolts 8c are in turn riveted to an outer sheet metal casing 10c, which surrounds the flat body 7c on the outside with play.

Abstract

Afin d'assurer un assemblage angulaire démontable de la lame d'un métier mécanique, une cheville en saillie (2a) agencée sur le montant latéral (1) est serrée par une vis de serrage (5) dans la verge (4) profilée creuse de la lame. La cheville en saillie (2a) comprend un corps plat (7a) formé d'une seule pièce avec le montant latéral (1), qui forme un cadre dans lequel des éléments élastiques (9a) amortisseurs de vibrations qui s'appuient sur la face intérieure du cadre reposent sur une rondelle métallique (8a) qui traverse le cadre et qui est rivée à une enveloppe en tôle métallique (10a) qui entoure avec jeu le côté extérieur du cadre (7a). Sur la partie supérieure de l'enveloppe métallique en U (10a) est rivée une barrette (12) sur laquelle la vis de serrage (5) est comprimée. Le montant latéral (1) n'est ainsi relié à la verge (4) de la lame que par les éléments (9a) amortisseurs de vibrations, ce qui amortit les vibrations entre le montant et la verge et évite des ruptures des matériaux notamment à de hautes vitesses d'exploitation de la machine.
