  • the invention relates to a clamping device according to the upper part of claim 1.
  • a clamping device of the type mentioned is known from the patent document DE 10 2016 200 180 A1.
  • This consists of a tensioning member movably mounted in a base body, a linearly movable actuator that is operatively connected to the tensioning member, a spring element that is operatively connected to the actuator and a rotatably mounted actuating element that is operatively connected to the spring element.
  • the spring element is designed as a tension spring (there reference number 24) because of the grooved plate (there reference number 15-19).
  • the invention is based on the object of improving a clamping device of the type mentioned at the beginning.
  • the operational safety of such a tensioning device should be improved in the event of a break in the spring element, which cannot be ruled out in principle.
  • the spring element is designed as a compression spring which can be compressed with the actuating element during tensioning.
  • the solution according to the invention is characterized in that a compression spring is used instead of the tension spring. This has far-reaching consequences and advantages - especially in connection with other training courses - which will be discussed in more detail below. 5
  • FIG. 1 shows in section the clamping device according to the invention in the open position
  • FIG. 2 shows, in section, the clamping device according to FIG. 1 on the way into the closed position

  • FIG. 6 shows, in perspective, the clamping device according to FIG. 1 30 in a first view in the closed position
  • FIG. 7 shows, in perspective, the clamping device according to FIG. 1 in a second view in the closed position
  • FIG. 8 in section, the loaded spring element according to FIG. 4 in a first side view
  • FIG. 9 shows in section the loaded spring element according to FIG. 4 5 in a second side view
  • FIG. 10 shows a side view of a housing section of the clamping device in which a latching mechanism is arranged

  • FIG. 13 shows in section the housing section which receives a movement mechanism and the latching mechanism and on which the actuating element is arranged.
  • the clamping device shown in the figures consists in a known manner of a clamping member 2 movably mounted in a base body 1, a linearly movable actuator 3 operatively connected to the clamping member 2, a spring element 4 operatively connected to the actuator 3 and one to the spring element 4 Actively connected, rotatably mounted actuating element 5, see in particular FIG. 1.
  • the clamping member 2 is designed as 25 clamping hooks and a counter bearing 13 is provided on the base body 1 for this clamping hook. It is also preferred that a centering mandrel 16 is provided on the base body 1 and the clamping member 2 is arranged at least partially in this centering mandrel 16. 30th It is now essential for the tensioning device according to the invention that the spring element 4 is designed as a compression spring which can be compressed with the actuating element 5 during tensioning.
  • the tensioning member 2 is arranged pivotably and 5 displaceably in the base body 1. It is also preferred that a guide slot 14 is provided on the end of the tensioning member 2 on the actuator side and a pin 15 engaging in the guide slot 14 on the end of the actuator 3 on the tendon side.
  • a curved guide 17 is preferably provided on the clamping member 210 and a guide pin 18 engaging in the curved guide 17 is provided on the base body 1, see in particular FIG. 2 in this regard.
  • an abutment element 6 for the spring element 4 to be arranged on the end of the actuator 3 facing away from the clamping element 2.
  • the spring element 4 is preferably designed as a helical compression spring.
  • the abutment element 6 is preferably designed in the shape of a plate.
  • the actuator 3 is arranged centrally and the spring element 4 is arranged concentrically to the actuator 3 on the abutment element 6.
  • the spring element 4 is preferably designed to be supported on the one hand on the actuator 3 and on the other hand on an abutment 7 that is operatively connected to the actuating element 5.
  • the abutment 7 is arranged at one end of a preferably cup-shaped housing 8 and the actuating element 5 is operatively connected to the other end of the housing 8. It is also preferred that the abutment 7 is designed like a cover for the preferably cup-shaped housing 8, with a through hole 19 for the actuator 3 being provided on the cover. In addition, it is preferred that the The bearing element 6 for forming a damper is designed to be mounted in the housing 8 in the manner of a piston and / or that the housing 8 is designed to be displaceably mounted in the base body 1.
  • a channel 9 is arranged on the abutment element 6, which is otherwise sealed in the housing 8, see in particular Figure 8.
  • a check valve 10 is preferably arranged on the abutment element 6, which is otherwise sealed in the housing 8 apart from the channel 9 , see in particular FIG. 9.
  • both the channel 9 and the check valve 10 are preferably provided for the fluidic connection of two spaces 8.1, 8.2 arranged on both sides of the abutment element 6.
  • the housing 8, in particular the spaces 8.1, 8.2, is preferably filled 15 with a damping medium, preferably oil.
  • the channel 9 has dimensions that prevent rapid expansion of the spring element 4 and / or that the check valve 10 is permeable in the event of a movement of the abutment element 6 relative to the abutment 7 leading to compression of the spring element 4 and to an expansion in the event of a movement of the spring element 4 leading movement of the abutment element 6 relative to the abutment 7 is sealing.
  • a rotating shaft 11 rotatably mounted on the base body 1 is preferably provided for the rotatable mounting of the actuating element 5.
  • a lever arm 20 is arranged on the rotary shaft 11.
  • an intermediate member 21 is articulated on the lever arm 20.
  • the intermediate member 21 is preferably designed in an articulated manner 30 connected to the housing 8.
  • the rotating shaft 11, the The lever arm 20 and the intermediate member 21 preferably form a movement mechanism 23 (see FIG. 13).
  • the intermediate member 21 is U-shaped and encompasses the rotary shaft 11 in the clamping position. 5 Likewise, the intermediate member 21 is preferably designed as part of a toggle lever device.
  • a latching mechanism 12 holding the clamping device in the open position 10 is preferably provided on the rotary shaft 11 mounted in the housing section 1.1.
  • the locking mechanism 12 consists of a plate 12.1 attached to the base body 1 with a locking projection 12.2, a ball 12.3 cooperating with the locking projection 12.2, a bearing plate 12.4 for the ball 12.3, which is displaceably but non-rotatably connected to the rotary shaft 11, and a Ball 12.3 is formed against the plate 12.1 pressing spring device.
  • the spring device is formed from at least one plate spring 12.5, see in particular FIGS. 10 to 13.
  • at least one latching projection 12.2 and at least one ball 12.3 be provided.
  • two or particularly preferably even three latching projections 12.2 or balls 12.3 are provided distributed over the circumference.
  • an end position interrogation device 22 which interacts with the actuator 3 and preferably operates inductively, is preferably arranged on the base body 1.
  • the clamping device is in an open position (see Figure 1).
  • the clamping member 2 is arranged completely in the centering mandrel 16 and the lever arm 20 is in an upper or lateral position.
  • the clamping device is kept open, since the ball 12.3 of the locking mechanism 12 is blocked by the locking projection 12.2.
  • An undesired independent movement of the actuating element 5 and thus an adjustment of the intermediate member 21 is thus excluded.
  • the spring force exerted by the spring element 4 is greater when clamping thicker workpieces than with thinner ones, since the spring element 4 is compressed more strongly here (compare FIGS. 3 and 4).
  • the flexible compression of the spring element 4 allows (which is very advantageous) a certain tolerance equal to 30 in the thickness of the workpiece while still having sufficient clamping force for very thin workpieces.
  • Another advantage of the tensioning device according to the invention is that by using a compression spring as the spring element 4, with the same (high) tensioning force, a smaller installation space is required for the spring element than in comparable designs with a tension spring.
