Definitions

  • the invention relates to a rack bar, in particular for the electroplating of printed circuit boards or the like, with a device for holding the rack bar on a mounting rail, which is divided into at least two spaced-apart, essentially horizontal goods rails.
  • the objects When objects are galvanized in electroplating baths, the objects are usually attached or attached to electroplating frames or rack rods and immersed together with them in a treatment bath. Power is supplied via mounting rails or goods rails, which are arranged across the treatment bath and to which the electroplating frames are attached.
  • the galvanizing frame rods made of stainless steel or iron, which are used, for example, for electroplating printed circuit boards, have been fastened to the mounting rail by means of screws or a frame head.
  • a rack rod is known from DE-PS 30 17 853, in which the rack head can be attached to the mounting rail by a clamping device designed as an eccentric.
  • rack head is not suitable for mounting rails that have at least two spaced-apart, essentially horizontal goods rails.
  • support rails of this type it has hitherto been customary to fasten a spacer on the frame rod which corresponds to the distance between the two goods rails and is pushed between them.
  • the rack rod is then attached to the mounting rail by rocker arms or screw connections, the counter brackets in the screw connection being in the form of platelets or wing nuts which can be turned 90 degrees and thus connect the rack rod to the mounting rail.
  • the invention has the task of creating a rack bar with a device for holding it on the mounting rail, in which an optimal fastening of the rack bar to the mounting rail is ensured.
  • the mounting device is a tensioning device on which at least one part is attached to the frame rod.
  • the part of the tensioning device fastened to the frame bar runs parallel to the goods rails and at right angles to the frame bar, so that it is ensured that the frame bar runs at right angles to the mounting rail.
  • the projection attached to the free end of the part of the tensioning device fastened to the frame rod ensures that the frame rod is guided securely on the mounting rail.
  • the frame rod can be easily removed by lifting it slightly forwards.
  • the clamping device in the form of two wedge pieces, any differences in the distance between the two goods rails can be easily compensated for, so that a good fastening of the frame rod to the mounting rail is always guaranteed.
  • the wedge connection enables continuous bracing, with only a small torque being required to brace the frame head, so that displacement or tilting of the frame bar is avoided and good contact removal from the mounting rail is ensured.
  • a rack bar 1 which is fastened to a support rail consisting of two parallel goods rails 2 and 3, has at its upper end a first wedge piece 4 which is fastened to the rack bar 1, for example welded on.
  • the wedge piece 4 has on the underside of its free end a projection 5 extending over the longitudinal side, which engages around the lower goods rail 3 of the mounting rail and serves as a guide for the latter. It is also possible to attach 4 projections 5 ′ or 5 ′′ (cf. FIG. 2) only at the two ends of the first wedge piece, which engage around the lower article rail 3.
  • a second wedge piece 6 is movably arranged, the inclined surfaces of the two wedge pieces 4 and 6 being displaceable on one another.
  • the second wedge piece 6 and the frame rod 1 have a continuous elongated hole 7 through which a screw 8 is guided, which at its free end passes through a groove 9 in the second wedge piece 6 arranged sliding block 10 can be tightened.
  • a plate 11 attached on the screw head side serves as a counter bearing.
  • the head of the screw 8 can preferably be countersunk in the frame rod and is designed as a hexagon socket screw 12, which can be tightened by means of a hexagon key 13, which is indicated in FIG. 1 by the arrows.
  • the sliding block 10 When tightening the screw 8, it is movable in the slot 7.
  • the sliding block 10 is also movably arranged in the groove 9, which is indicated by the arrows.
  • the design of the elongated hole ensures that the bracing of the two wedge pieces 4 and 6 between the two goods rails 2 and 3 can be carried out continuously and with a low torque, thereby ensuring that the frame rod does not shift or tilt with respect to the mounting rail .
  • the frame rod 1 can also be designed as a square tube (not shown), in the interior of which a copper or brass core (not shown) is inserted with a press fit, as described in more detail in DE-PS 30 17 853.
  • the screw 8 within the square tube must be surrounded by a stainless steel sleeve (not shown) or the like in order to prevent the square tube from being compressed when the screw is tightened.
