Definitions

  • the invention relates to a clamping and / or joining device for the precise, punctual fixing of two objects, in particular flat workpieces, such as sheets or the like. According to the preamble of claim 1.
  • a device is known with which a bending misalignment of the workpiece support can be counteracted under load.
  • this device does not allow a firm connection of the workpiece support to the actual device frame and requires an articulated connection to the device frame, which in turn, if jamming of the coaxially movable workpiece support is to be prevented, must additionally be pivotally connected to the die holder.
  • a device is known, in which case it is specifically a device for joining two sheets, which are first clamped together with a so-called hold-down device and then by pressing the joining die through material deformation between the male and female molds get connected.
  • the actuating mechanism is designed in the form of a toggle lever mechanism that is common in clamping devices.
  • the subject matter of the invention is a tensioning and / or joining device.
  • the invention is based on the object of improving a device of the generic type, which is thus actuated, for example, by an actuating cylinder with the interposition of a toggle lever mechanism, and with simple constructive means that the unavoidable bending no longer relates to the axial precise alignment between the workpiece support and dislodging clamping or joining stamps.
  • This solution is based on three essential measures, namely on the one hand to hold the workpiece support by a fixed connection to the fixture frame in an axially accurate assignment to the clamping or joining die, on the other hand to the division of the counterholder into two parts and finally to the intermediate arrangement of a support curved surface between the lower end of the workpiece support and the lower part of the counter holder. If the load-bearing lower part bends under load and, as mentioned, only moves in the 1/100 mm range, the central support of the workpiece support is retained by the intermediate arrangement of the curved support.
  • the clamping and / or joining device basically and in a known manner consists of a device frame 1 with a clamping or joining punch 2 which can be actuated by a toggle lever mechanism KM, under which in a cantilever-like counter-holder 3 of the device frame 1 there is a workpiece support axially aligned with the clamping or joining punch 2 4 is arranged.
  • the exemplary embodiment is a special type of device, namely with a double drive on the one hand for tensioning and on the other hand for pressure joining.
  • the counter-holder 3 which is firmly connected to the device frame 1, consists of a part 3 'which receives the clamping and joining load and from a the workpiece support 4 axially in the direction of Load displaceable part 3 '' is formed, and that between the lower end 4 'of the workpiece support 4 and the load-bearing part 3' a positionally fixed ball is arranged as a support 5.
  • the joining device with hold-down device is shown, which is actuated by a toggle lever mechanism KM, while the tensioning or jointing punch 2 is actuated by a further toggle lever mechanism KM1, which mechanisms receive their drive from actuating cylinders, not shown.
  • a toggle lever mechanism KM which mechanisms receive their drive from actuating cylinders, not shown.
  • the joining die 2 is provided with a male part 7 and the workpiece support 4 is provided with a female die 8, and furthermore the joining die 2 is mounted in a clamping arm 13 which can be pivoted on the device frame 1 and is coupled to the toggle lever mechanism KM, which forms the aforementioned hold-down.
  • the load-bearing part 3 ' is arranged as a central cantilever extension 6 on the device frame 1, to which the part 3' 'is assigned in the form of two carrying extensions 9 arranged laterally adjacent to the device frame 1.
  • a cross member 10 carrying the workpiece support 4 is arranged on this a cross member 10 carrying the workpiece support 4 arranged.
  • the part 3 ' is advantageously arranged on the device frame 1 in a height-adjustable manner in the direction of the joining load, as indicated by arrow P.
  • the support 5 in the form of a ball it is, as can be seen from FIG. 1, mounted in a spherical cap 11 of the part 3 'and fixed in the spherical cap 11 with a holding element such as screw 12.
  • a holding element such as screw 12.
  • a hemisphere or semi-cylindrical bar could of course also be used, and a corresponding shaping of the part 3 'would also be possible in this area immediately below the end 4' of the workpiece support 4.
  • Only a spherically curved support is essential in order to ensure the centricity of the support 5 at the end 4 'of the workpiece support 4 when the part 3' is bent downward under load.
