Definitions

  • the angle clamp according to the present invention is suitable for solving this problem.
  • it consists of two legs arranged at an angle to one another made of a mechanically resistant material, preferably metal, each of which is provided on its inside with a tensioning device acting in the direction of the apex of this angle.
  • the legs are rectangular and are preferably made of a hollow metal profile for weight reasons.
  • the angle between the two legs is invariably fixed and is 90 ° for the most common uses.
  • the angle between the two legs is variable and adjustable at will.
  • the two legs are connected to each other by a joint and can be in a desired angular position, e.g. fix with a clamping screw.
  • clamping devices provided on the two legs.
  • One of these is derived from the usual screw clamp used for gluing workpieces. It consists on the one hand of a clamping jaw acting against the workpiece and on the other hand of a threaded rod counterpart with handle. Both parts can slide freely on the leg. While the clamping jaw only surrounds the leg in a U-shape on three sides, the counterpart is designed so that it surrounds the leg all around. When a force is exerted between the clamping jaw and the counterpart, the clamping jaw remains freely displaceable on the leg, while the counterpart is fixed in its position on the leg by tilting. This makes it possible to exert a force on the clamping jaw acting against the workpiece by turning the threaded rod.
  • the tensioning device consists of a block that can be fixed on the leg in various longitudinal positions, consisting of a metal piece that surrounds the leg from its inside in a U-shape, which is regularly attached to the inside of the leg by means of two bolts with round heads attached on its underside Spaces milled slots are positioned and held in place by a transverse clamping screw.
  • the block On its upper side, the block carries a screw nut fastened by welding or brazing, which serves as a guide for a threaded rod arranged parallel to the leg.
  • the threaded rod carries on its end facing away from the workpiece a hexagon nut and on the end facing the workpiece a press ram which is freely rotatable relative to the threaded rod. By turning the threaded rod with the help of the hexagon nut, this end plate can be pressed against the workpiece and thus exerts a force with which the workpieces to be glued or glued are pressed together.
  • an appropriately shaped support wedge is inserted on the inside of the angle between the two legs, which is used during the gluing period supports the workpieces on their inside and a mutual one Movement along the adhesive joint prevented.
  • the surfaces to be glued or glued are advantageously provided with a groove and matching groove to prevent mutual slipping.
  • FIGS. 1 to 4 show an angle clamp according to the invention, in which the two legs ( 1 , 2) of rectangular cross section are directed perpendicular to each other.
  • the two clamping devices in an embodiment derived from the usual screw clamp, clamp the three workpieces (7, 8, 9) to be glued, which each form an angle of 45 ° between them, against one another.
  • the two clamping devices each consist of the clamping jaw (3) which can be moved on the leg, the counterpart (4) which surrounds the leg in a U-shape, the threaded rod (5) and the handle (6).
  • the clamping devices are each pushed on their legs up to the stop on the workpieces and then firmly tightened by turning the handle (6), the clamping jaw being pressed against the workpieces on both sides.
  • a suitable support wedge (not shown in the figure) can be placed as required.
  • Figure 2 shows an embodiment of the angle clamp, in which the two legs (11, 12) form an adjustable angle on the joint (17) and can be fixed against each other by a clamping screw (18).
  • the tensioning devices (14) shown in the figure are shown in a second embodiment, consisting of a block which can be fixed on the leg by means of bolts in elongated holes (16) and a device which consists of a tensioning screw and end plate and is mounted thereon.
  • Figure 3 shows a clamping device of the first embodiment in detail.
  • the jaw (3) is placed with its U-shaped lower part on the leg (1) and can be freely moved on the latter.
  • the counterpart (4) completely surrounds the leg (2) with its lower part (18) and is therefore, when exerting a lateral force, clamped in position on the latter by tilting.
  • the thread axis can be pressed against the upper part of the clamping jaw (3), which in turn presses in the direction of the workpiece.
  • FIG. 4 shows the second embodiment of the tensioning device used in FIG. 2 in detail: on the leg (1), the block (21) that surrounds the leg with its lower part is shown, which with the help of the two bolts (22) can be seen in FIG keyhole-shaped elongated holes (16) on the top of the leg can be fixed in its longitudinal position.
  • the clamping screw (23) is used for further fastening of the block.
  • the screw nut (24) is welded onto the upper part of the block. It serves to receive the threaded rod (25), which carries at one end a hexagon nut (26) firmly connected to the latter. At its other end, the threaded rod carries the freely rotatable press ram (20), which presses against the workpiece (not shown in the picture) by tightening the threaded rod.
