Definitions

  • the invention relates to a toggle lever tensioning device Devices for the end position query, consisting of a linearly controlled actuator adjustable by a drive and from a twisted link attached to it, which with a Articulated pivot arm on the fixture head piece connected is.
  • Such toggle clamps mainly come in Area of the auto industry for the determination of bodies or Body parts in the course of production lines for use, taking control of the tensioners usually programmed is done, which is why the jigs with devices equipped for the so-called end position query are, with the help of signals for the achieved clamping and Opening positions of the clamping arms for program control be delivered.
  • the opening position of the Clamping arms are usually the back swing angle or opening angle of> 90 °, i.e. driving through them Swinging paths cost time accordingly, although in the course of modern Rationalization requirements even counted in seconds , which in turn means that, where possible, one should short opening positions for such clamping devices would like to have available or adjustable.
  • the object of the invention is such fixtures while maintaining the end position query to train in a simple way that the opening position of the tensioning arm is no longer solely dependent on the End of stroke position of the actuator depends, but the opening position or the opening angle of the tension arm between the two extreme positions possible per se is.
  • the toggle clamp device still consists of one linearly guided actuator 5 adjustable by a drive 1 and an articulated intermediate member 2, the with a rotatably mounted on the device head piece 6 Clamping arm 4 is articulated, being between the Device head piece 6 and the drive 5 one of the linear guided actuator 1 penetrated intermediate piece 7 arranged is.
  • the relevant illustration in Fig. 1 provides a special training of an actuating mechanism that none more detailed explanation is required, since this is not from is of direct interest, i.e., is only of interest here the connection area of the drive 5 to the device head piece 6, for which it is essential that in the access area DB of the Actuator 1 in the intermediate piece 7 an adjustable opening position stop 9 for one at the top of the Actuator 1 arranged link link 10th is arranged.
  • the opening position stop 9 is, as in 1 and 2, in the form of an actuator 1st at least partially comprehensive sleeve 9 'with a Gear area 12 formed. Furthermore, the Opening position stop 9 in a recess 11 of the Intermediate piece 7 matching and fixable on this filler 13 associated with a counter-tooth area 12 '.
  • This opening position stop 9 is simply set in that the filler 13 is released, the stop in the desired Open position on the lower flank F of the intermediate link piece 10 created and then the filler 13 is fixed again, the setting of the stop 9 is held by the meshing teeth.
  • an open position stop 9 is also of interest insofar as as a result of backward swiveling loads by the tension arm, which can sometimes be considerable, from the bottom of the actuating cylinder to be kept away, which is often with permanent load already to break through the cylinder arch there have touched the piston. It is also advantageous on upper end of the open position stop 9 a sensor stop extension 9 '' arranged for the lower link link 10 a sensor 14 is provided, the when placing on the extension 9 '' with the part of a Head piece 6 arranged sensor system 15 brought into operative connection and the opening end position of the clamping arm 4 displays.
  • the two parts of the stop sleeve 30 are made of one unscrewed from the actuator end 1, with external thread 34 provided intermediate link 35 and from an internally threaded 36 provided on the intermediate link 35 screwed outer sleeve 37 formed.
  • Fig. 5A and C correspond to the Tensioning positions of the tension arms 4, but this with different Length settings of the stop sleeve 30, which is illustrated in detail in Fig. 6A, B and so far no further explanation is required.
  • State of the stop sleeve 30 corresponds to this or leads this to a maximum opening angle of the tension arm position, as seen from Fig. 5B.
  • the stop sleeve 30 more or less "screwed on" (see Fig. 5C, D), so leads this leads this leads to a more or less large reduction in the opening angle ⁇ .
  • the whole adjustability is here immediately moved into the actuator 1 itself and has also the great advantage that the end position sensors 33 can be arranged stationary in or on the head piece 6, since the end position sensor 32 as parts of the stop sleeve 30 automatically set when setting. Not Access openings are shown on the side of the head piece and means for fixing the once on the Stop sleeve 30 made setting.
  • Fig. 7A, B and 8 Constructively different, but on the same principle as that 5, 6 embodiment described, is after Fig. 7A, B and 8 formed, Fig. 7A of the clamping position and FIG. 7B a relatively large (for example 120 °) open position corresponds to the tension arm.
  • Fig. 7A of the clamping position and FIG. 7B a relatively large (for example 120 °) open position corresponds to the tension arm.
  • the part 40 of the actuator which engages in the head piece 6 1 provided with external thread 41 on the end position transmitter 42, 43 for end position sensors arranged stationary in the head piece 6 33 are screwed on to fix the position.
  • the one with an external thread 41 is expedient and advantageous provided part 40 as an extension connected to the actuator 1 40 'of the actuator 1 is formed.
  • the end positioner 43 for the open position is part of a sleeve 45, which is also the end stop with its lower end for the open position, that is along the one with an external thread 41 provided extension 40 'would be adjusted can.
  • FIGS. 8, 9, i.e., here, too, is an access opening 44 in the Head piece 6 provided, which is covered with a closure 46 and at the same time designed as a position fixing means is, in the form of an inward Closing plate embossed web 47, for its engagement corresponding grooves 48 on the screw-adjustable elements are provided.
