Definitions

  • the invention relates to an adjusting device for the clamping force in a clamping device with two clamping parts that can be moved relative to one another, a force amplifier generating the clamping force and a drive thread spindle that actuates the force amplifier and is guided in an internal thread of a spindle carrier, which, for its own actuation, has a spindle end projecting axially from the spindle carrier and one has a fixed stop, for which a stop device that can be preset depending on the amount of clamping force is provided on the spindle carrier, in particular in the case of a machine vise with a hollow overdrive spindle forming the spindle carrier, which can be rotated in a spindle nut connected to one of the clamping parts and in the direction of rotation via a torque coupling can be coupled with the coaxially arranged drive screw.
  • the coupling pin 9 In the engaged position, the coupling pin 9 is held by a spring-loaded ball 11, which in turn engages in a locking recess 12 formed on the coupling pin 9.
  • the overdrive spindle 4 is first taken along when the drive threaded spindle 5 is rotated via the torque coupling 8. If the clamping parts then rest on the workpiece and the overdrive spindle 4 is no longer adjustable, the torque clutch 8 disengages, so that only the Drive screw 5 can be rotated further to actuate the power amplifier.
  • the second stop piece 18.2 is further along the helical adjustment path 14 by an angle of 390 °, the third stop piece 18.3 by an angle of 720 °, the fourth stop piece 18.4 by an angle of 1110 ° and the fifth and last stop piece 18.5 by four full revolutions, i.e. an angle of 1440 ° further.
  • the stop pieces 18.1 to 18.5 are supported on an adjusting sleeve 21, which is axially immovable and rotatable on the outside of the cage sleeve 15.
  • the pocket 27.4 is now in the direction of rotation of the adjusting sleeve 21 directly behind the fourth stop piece 18.4, which is thus still blocked, while the first three stop pieces 18.1, 18.2, 13 are released by the pockets 27.1, 27.2, 27.3 and the stop projection 13 on its adjustment path Let 14 pass until it comes to rest on the fourth stop piece 18.4.
  • the last rotation by another 30 ° gives the relationships shown in FIGS. 11 and 12.
  • the pockets 27.1 to 27.4 have released the first four stop pieces 18.1 to 18.4, but the adjusting sleeve 21 still blocks the fifth stop piece 18.5, so that this now limits the stop projection 13 on its adjustment path 14.
