  • annular beads 24 are provided, which also delimit a groove 25 the drive spindle 21 on both sides of the groove 25 threads 26 and 27.
  • the thread 26 is right-handed, while the thread 27 is left-handed (or vice versa).
  • the threads 26 and 27 can be connected to the threaded holes 18 and 19, which are left-handed in the projections 16 and 17 of the slide 14 and 15.
  • the carriages 14 and 15 can be equipped with interchangeable jaws 30 and 31 in order to enable different clamping processes according to the particular application.
  • clamping jaws 30 and 31 are advantageously fastened to the slides 14 and 15 with the aid of screws 32 and 33.
  • the body 2 of the vice 1 has a transverse through hole 34 in the middle.
  • the axis of the bore 34 is arranged perpendicular to the longitudinal axis of the U-shaped body.
  • clamping means which are designated 35 as a whole.
  • the clamping bodies 35 advantageously have the shape of cylinders, and the end facing the spindle 21 has the shape of a fork 36 in order to provide a positive connection between the fork 36 and the bead 24 and the groove 25 formed in the center of the spindle 21 enable.
  • An elongated hole 37 is provided in the cylindrical clamping bodies 35, on the inside of which a toothing 38 is formed.
  • a key 39 can be brought into engagement with the toothing 38, which key e.g. is provided with a toothed end 40, so that the clamping body 35 can be moved using the key 39.
  • a continuous threaded hole penetrates through each cylindrical clamping body 35 and receives a clamping screw 41 which can be rotated via a key 42 for clamping or releasing the clamping body 35.
  • FIG. 2 shows the vice 1 with the corresponding U-shaped body 2 and the drive spindle 21 in the disassembled state.
  • the clamping jaws 30 and 31 to be attached to the slides 14 and 15 are designed as self-centering clamping jaws which can act on the workpiece from the outside in and have prismatic receptacles, e.g. for clamping a cylindrical body (not shown).
  • a bearing block 50 is provided which comprises the annular beads 24 and the corresponding groove 25 formed in the spindle 21 in a bridge-like manner.
  • the bearing block 50 is at the bottom of the body 2 of the Vice 1 attached.
  • adjustment bores 51 are formed, in the area of which a bracket 52 can be positioned and fixed, which engages in a form-fitting manner in the groove 25 delimited by the beads 24.
  • the bracket 52 is arranged in the area of a bore 51 and thereby enables the center of the drive spindle 21 to the body 2 of the vice 1 to be determined.
  • This device also includes a row of pins 53 with a square cross section. It is the task of these pins to fill the space (after the attachment of the bracket 52) on one or both sides of the bracket 52.
