Definitions

  • the present invention relates to a tensioning device according to the preamble of patent claim 1.
  • Such a clamping device is known for example from CH PS 655.458.
  • the known clamping device has proven itself in particular for clamping plates on two of their parallel and rectilinear side edges. Such clamping of plates is required, for example, if the plate is to be provided with a glued-on border.
  • a disadvantage of the known clamping device is that at least one of the clamping jaws is firmly anchored to the associated tube. If the outer contour of the workpieces (plates) to be clamped deviates from a straight line and the shape of the clamping jaws has to be adapted to this outer contour, at least one of the tubes had to be exchanged for another with the clamping jaw adapted to the special outer contour in the known clamping device. Likewise, plates can not be satisfactorily clamped on opposite, straight-line but not exactly parallel edges with the known clamping device.
  • the proposed clamping device has the features specified in the characterizing part of patent claim 1. So that the jig a set can also be assigned with any number of clamping jaws which are adapted to the existing shapes and / or contours with regard to their shape and / or their direction with respect to the spar.
  • the tensioning device characterized in claim 2 is particularly advantageous.
  • the tensioning device 10 shown in FIGS. 1 and 2 has a spar 11, for example made of a square tube.
  • a first square tube 12 is on the end region of the spar 11 that appears at the bottom in FIGS. 1 and 2 pushed and blocked with a pin 13 on the spar 11.
  • the spar 11 has a series of continuous transverse bores 14 (FIG. 2; omitted in FIG. 1).
  • the first square tube 12 can be moved after pulling the pin 13 on the spar 11 and fixed again at the height of one of the holes 14.
  • a second square tube 15 is pushed onto the end region of the spar 11 appearing at the top in FIGS. 1 and 2.
  • This second square tube 15 is longitudinally penetrated by a threaded spindle 17 provided at one end with a handle 16, which is rotatably mounted at 18 in the tube 15 but axially immovable.
  • the threaded spindle 17 is screwed into a nut piece 19 firmly anchored in the spar 11.
  • the second tube 15 can be moved continuously along the spar 11 by rotating the threaded spindle 17.
  • a square or hexagon which can be rotated by a pneumatic screwing tool can also be provided.
  • a projecting pin 20 is welded to both the square tube 12 and the square tube 15.
  • This pin 20 has a longitudinal bore 21 provided with an internal thread.
  • the pin 20 has a section 22 with a polygonal, for example square, outer profile (see also FIG. 1), which then merges into a section 23 with a cylindrical outer profile.
  • the pins 20 are used to mount the clamping jaws 24, which are indicated only by dashed lines in FIG.
  • a first embodiment of a clamping jaw 24 is shown in different types of mounting on the tube 12 or 15.
  • the clamping jaw 24 consists of a solid or tubular, straight round or square profile which has a continuous transverse bore 26 in the middle. On both sides of this transverse bore 26 extend clamping arms 27, 28 which e.g. are provided with a covering 29 made of rubber. At one end of the bore 26 there is a countersink or a groove 30, the inner profile of which is the same as the outer profile of the section 22 or the width of which corresponds to the width of the section 22. At the other end of the bore 26 there is also a countersink or a groove 31, the inner profile of which is circular and of greater diameter than the diagonal of the square section 22 or the width of which is greater than this diagonal.
  • the clamping jaw 24 is mounted on the pin 20 as shown in FIG. 4, it can also rotate around the pin 20 after the flat-head screw 25 has been screwed on, since there is no positive connection between the groove 31 and the section 22 but only a positive connection . To turn the clamping jaw 24, however, the friction generated by the frictional connection must be overcome.
  • an intermediate piece 32 which has a continuous longitudinal bore 33 for receiving the pin 20.
  • the longitudinal bore 33 opens at one end of the intermediate piece 32 into a countersink or into a groove 34, the inner profile of which is opposite to the outer profile of the section 22 or whose width corresponds to the width of the section 22.
  • the longitudinal bore 33 opens centrally in a projection 35 formed on the end face of the intermediate piece 32, which has the same outer profile as the section 22.
  • a screw 25 ' is used, which not only passes through the transverse bore 26, but also the intermediate piece 32 before it engages in the internal thread in the pin 20.
  • the jaw is analogous to Fig. 3, i.e. with respect to the tube 12, 15 non-rotatable and in Fig. 6 analogous to Fig. 4, i.e. mounted rotatable against frictional connection.
  • FIG. 7-11 an embodiment of a jaw 24 'is shown.
  • This jaw 24 ' has two mutually perpendicular clamping arms 27', 28 'from a casing 29' provided with a flat profile.
  • the clamping arms 27 'and 28' extend from a mounting block 36, which is formed analogously to the central portion of the clamping jaw 24 between the clamping arms 27 and 28 of FIGS. 3-6 and which serves to receive the pin 20.
  • the tensioning arms 27 ', 28' are expediently welded to the fastening block 36 or formed integrally therewith.
  • FIGS. 12 and 13 There are cases, for example, when a glue joint has to be pressed between two butt-jointed panels, where the span of the clamping device is not sufficient to bridge both panels.
  • the "clamping jaw” consists essentially of a plug pin 37, which is fixed with the interposition of the intermediate piece 32 by means of the screw 25 'on the pin 20 of the tube 12, 15. These plug pins 37 are intended, so to speak, to engage without play in bores which have been prepared in the panels to be joined together in the vicinity of the glue joint to be pressed.
  • the clamping device described can also be used with a limited length of the spar 11 to clamp two workpieces, in particular two plates, the dimensions of which exceed the actual span of the spar 11.
