Definitions

  • the invention relates to a toggle lever clamping device for clamping workpieces, primarily for use in body construction, with an axially adjustable part which can be actuated by the toggle lever joint.
  • Toggle lever clamping devices are known in particular as manifold embodiments that can be actuated by pressure medium.
  • An advantageous embodiment of this type consists of a housing with a cylinder space for the piston, on the free piston rod guide means for the piston rod and a piston rod bolt are arranged, which is connected via a tab to the toggle joint of a workpiece-clamping angle lever, which is on a pivot bearing mounted in the housing.
  • Guide means for the piston rods consist of the ends of the piston rod bolt and guide grooves arranged in the housing and running in the axial direction of the piston rod for guiding these ends (DE-AS 22 22 686).
  • DD-A-138643 discloses an electromotive holding device with which solid bodies can be positively or non-positively picked up, held and set down.
  • an electric motor is controlled in the holding device, which sets a push rod into translational movement via a screw drive and thus actuates toggle levers linked to it, which have a connection to tensioning arms, whereby the tensioning arms articulated on a crossbar are spread or retracted to pick up or set down a rail vehicle wheel set.
  • the electric motor of the device disclosed in this document is neither provided with a hollow shaft nor driven via its shaft em pinion.
  • the invention has for its object to provide a toggle lever tensioning device of the generic type so that the construction is significantly simplified compared to the prior art and the disadvantages of the prior art are avoided.
  • toggle lever tensioning device is also easy to assemble, since no rigid pipes, screw connections, etc. have to be laid, but only flexible cables are used, which are then connected to the tensioner by means of plugs.
  • the axially adjustable part is replaced by a screw spindle, which can have, for example, a steep thread, in particular a trapezoidal thread or the like, which works in a suitable screw nut which is driven by an electric motor via a hollow shaft, so that there is a stepless adjustment of the spindle and thus also of the toggle joint in both axial directions.
  • a screw spindle which can have, for example, a steep thread, in particular a trapezoidal thread or the like, which works in a suitable screw nut which is driven by an electric motor via a hollow shaft, so that there is a stepless adjustment of the spindle and thus also of the toggle joint in both axial directions.
  • the drive of the electric motor takes place via a gear, wherein one of the gears or pinions can be provided with a corresponding thread for the spindle designed as an axially adjustable part.
  • the reference numeral 1 designates an electric motor with a design which is intended for the respective embodiment and which, in the embodiment according to FIG. 1, has a recess 2 in the axial direction into which a screw spindle 3 which is infinitely adjustable in the direction X or Y can enter. 4 with a mounting or end plate is designated, but also can be omitted.
  • a housing 5 of the toggle lever tensioning device is arranged coaxially with the electric motor 1 and is connected to the electric motor 1 in a manner not shown, for example by screws, firmly but releasably.
  • the housing 5 has in the end area to the electric motor 1 a radial extension 6, in which a threaded nut 7 is arranged, the thread of which matches the thread of the screw spindle 3.
  • the threaded nut 7 is connected to a hollow shaft 8 of the electric motor 1.
  • the hollow shaft 8 thus has the recess 2 for the entry of the screw spindle 3.
  • the screw spindle 3 is screwed into the screw or threaded nut 7 in at least several threads in every possible position of the parts during operation, but also protrudes from the threaded or screw nut by a considerable length in the clamping position shown in FIG. 1 7 into the recess 2 of the hollow shaft 8.
  • the parts to be tensioned are not shown in the drawing. 1 and 3 are spaces between one Clamping jaw 9 and an abutment 10 are shown, which of course do not need to be present in practice or not in this size.
  • the clamping jaw 9 is arranged so as to be pivotable in the direction A or B via a clamping part 11 and a pivot axis 12 fixedly arranged on the housing 5.
  • a connecting bracket 14 is coupled via a pivot axis 13, which is pivotally connected at its end part facing away from the pivot axis 13 via a bolt 15 to a part 16 which is coupled to the screw spindle 3.
  • the pivot axis 15 is mounted in part 3.
  • the screw spindle 3 engages with a length section in the part 16 and can be screwed into the part 16, for example.
  • a roller 17 or 18 is mounted, each in a groove or longitudinal guide 19 or 20 of the housing 5 parallel to the longitudinal axis of the screw 3 and thus also parallel to the longitudinal axis of the housing 5, i.e. in the direction X or Y, are guided with low friction.
  • the rollers 17 and 18 can also be ball bearings on the ends of the bolt 15 are arranged and their outer housing roll in the grooves 19 or 20 or the like. Otherwise, the training and leadership can be made as in DE-AS 22 22 686.
  • the hollow shaft 8 is driven in a certain direction, as a result of which the threaded nut 7 is moved in the corresponding direction of rotation, which results in a corresponding longitudinal displacement of the screw spindle 3, for example in the X direction, so that, for. B. pivots the jaw 9 in direction B, so it opens.
  • an electric motor 1 drives a pinion 22 via a shaft 21, which meshes with a toothed wheel 23, which has teeth on the inside - at 24 - which interacts with the screw spindle 1 and thereby, depending on the direction of rotation of the electric motor 1, the screw spindle 3 in the direction X or moved axially in the Y direction.
  • This can also be a worm gear.
