Definitions

  • the invention relates to a seat tensioner with a Guide column, with a clamping claw and with clamping devices, through which the arranged on the guide column Clamping claw axially adjustable in relation to the guide column is.
  • the invention is therefore based on the object To design ride-on clamps of the type mentioned at the beginning, that the clamping accuracy and its reproducibility is improved.
  • This task is the beginning of a ride-on tensioner mentioned type in that means for restriction the mobility of the clamping claw around the guide column are provided.
  • the invention has the advantage that the means for Limitation of the rotational mobility limit positions of the Angular position of the clamping claw compared to that as the axis of rotation acting guide column and so the Clamping claw defines between the two limit positions is adjustable, so the result is the clamp in the a limit position always in the same place of the exciting part attacks and in the other limit position in a specific area that is free for the user can be pivoted.
  • a particularly preferred embodiment of the invention is characterized in that the means for Restriction of the mobility by one on the Guide ring arranged positioning ring are formed which has a stop that with a Limiting swivel range on the clamping claw arranged counter-stop cooperates.
  • This Positioning ring has the advantage that it itself rotatable relative to the guide column and only in one certain angular position in relation to the guide column can be fixable, so the guide column itself cannot must have rigidly specified structures, the one certain orientation of the means to limit the Rotational mobility and thus the orientation of the Force claw.
  • Embodiment One preferred in terms of simplicity of construction Embodiment is characterized in that the Counterstroke by a sector with one against the other areas of the clamping claw outside the sector smaller radius and the stop designed as a pin is that in the sector with the smaller radius protrudes.
  • the flexibility in using the ride-on tensioner is increased if the sector with the smaller radius several times, distributed over the circumference of the clamping claw this is trained. It is also advantageous if the Positioning ring detachably arranged on the guide column is because in cases where there is a restriction of the Rotational mobility of the clamping claw is not desired Seat tensioner according to the invention is also used can be done by simply removing the positioning ring from the Guide column is removed.
  • the ride-on tensioner according to the invention is for one horizontal use, that means horizontal orientation the guide column also suitable, since even in the Usually present asymmetrical structure of the clamping claw is prevented by stop and counterstop that the clamp always twisted around the guide column, until the center of mass reaches its lowest point.
  • the clamping means through a into a thread of the guide column engaging clamping screw are formed, and that the Clamping screw through one on a thrust bearing supported clamping lever is rotatable. It is the use of the thrust bearing is particularly advantageous, because the clamping forces are significantly increased through its use can be because when the clamping lever is turned overcoming frictional forces essentially between the Clamping thread and the clamping screw localized and thus are also effective for clamping.
  • a ride-on tensioner 1 is shown a guide column 2 with an axial through hole 3 having.
  • On the guide column 2 is rotatable Clamping claw 4 arranged on which a clamping hook 5 is trained.
  • the through hole 3 is in a threaded receptacle 6 screwed threaded pin 7 arranged with which the Ride clamp 1, for example, on not shown itself can be fixed on a machine table.
  • a clamping thread 8 formed, in which a clamping screw 9 engages the together form the clamping means 8, 9 around the clamping claw 4 to adjust axially on the guide column 2 and so on the clamping hook 5 a workpiece or the like. on the Clamp the machine table.
  • the clamping screw 9 can can be rotated by a clamping lever 10, which over a Axial bearing 11 is supported relative to the clamping claw 4.
  • a positioning ring 12 is detachably on the guide column 2 arranged in its rotational position opposite the Guide column 2 can be fixed by locking screws 13 is.
  • On the positioning ring 12 is a stop 14 Pin 15 placed. This pin 15 protrudes in one of the Claw 4 trained sector 16 into one compared to areas outside of sector 16 the clamping claw 4 has a smaller radius and so than Counter stop 17 acts so that stop 14 and Counterstop 17 means 14.17 to limit the Rotational mobility of the clamping claw 4 around the guide column 2 form.
  • This sector 16 with the smaller radius cannot Exemplary embodiments shown in the drawing distributed several times over the circumference of the clamping claw 4 this be trained.
