Definitions

  • the invention relates to a clamping and deformation tool with in the manner of a vice of the type specified in the preamble of claim 1, cf. DE-C-32 11 521.
  • Clamping tools with spindle drive which can be operated by hand, so-called vices, are known in different designs. It is also known to design the jaws differently and interchangeably depending on the intended use, for which purpose DE-C-34 30 814 or DE-A-41 37 927 is only mentioned here as an example. The problem of designing interchangeable jaws is comparatively old, so that very old solutions are also known, for example DE-C-28 49 92 or DE-C-34 14 34.
  • Tools for these work tasks usually consist of two parts, they can be in the form of plates as cutting or embossing tools and the like. on the one hand and as a counterpart or anvil on the other hand. These plates must be exactly aligned with each other.
  • DE-C-32 11 521 shows a clamping jaw that can be adjusted via a pedal to increase the clamping force.
  • One way to use jaws with screws and guide pins US Pat. No. 4,519,592 also shows interchangeably to be provided on such a device, but at least one screw must be turned over a plurality of thread turns in order to loosen the respective clamping jaws for replacement or vice versa to fix them in the working position.
  • the object of the invention is to create a multi-function tool which can be quickly adapted to the different purposes and with which not only high clamping forces but also deformation forces can be applied if necessary.
  • the L-shaped design of the tool jaws with corresponding guides in the other tool elements enables precise alignment of the tool jaws.
  • the design of the quick-change device with a pulling head and a spring-loaded traction pin makes it possible, depending on the preload, to provide a manual actuation by means of a push button, whereby a very compact design is possible, for example, due to an inner bore in the push button and the possibility of actuating the preload nut guaranteed thereby.
  • a foot-operated linkage is available, whereby the laying of the attack level of the actuation linkage in a level in front of the stationary tool jaw in turn leads to a very compact and simple construction.
  • the tool is fastened to the base body 2, in which a slide 3 can be moved in guide rails 4, on a workbench, not shown in dash-dot lines.
  • the movement of the carriage 3 is brought about by an infeed element which, in the example shown, consists of a spindle sleeve 5 mounted in the base body 2 and a spindle 6 fixed in the carriage, which engages in the spindle sleeve 5.
  • the front part of the spindle sleeve 5 is stepped and axially displaceably mounted in a stepped bore in the base body.
  • a bushing 7 is rotatably arranged on the spindle sleeve 5, which is seated on one side on a collar of the spindle sleeve 5 and on the other hand is fixed in the axial direction with a spring ring 8.
  • a ring groove 9 of the bushing 7 engages with a cam 10 in the base body 2 about a pin 11 pivotable linkage 12.
  • the linkage 12 is adjustable in height and can be actuated by means of the pedal 12a.
  • the bushing 7 with spindle sleeve 5 and spindle 6 and thus the slide 3 can be moved longitudinally by actuating the linkage 12.
  • the carriage 3 can also be moved by rotating the spindle sleeve 5 on the spindle 6.
  • the bushing 7 is supported on the base body 2 with the spindle sleeve 5.
  • a hand lever or toggle 13 is arranged in the foremost part of the spindle sleeve 5 in order to carry out the rotary movement.
  • tool jaws 14 are fastened in an exchangeable manner.
  • the tool jaws 14 are each L-shaped on the side facing the base body 2 or slide 3 and engage positively in corresponding recesses 22 of the base body 2 or slide 3.
  • the tool jaws 14, each with fixed pins 15 in the base body 2 and in the slide 3, which engage in bores in the tool jaws 14, are positioned against lateral displacement.
  • the traction pin 16a consists of a threaded part and a head 16, the head 16 being flattened and resting with its flattening on a recess 22 in the tool plate receptacle of the base body 2 or the slide 3.
  • the nut 17 is rotatable in the stepped bore 23 on the threaded part of the pull pin 16a.
  • the spring 19 is arranged between an annular extension of the nut 17 and the annular surface of the stepped bore 23. When the head 16 of the tension pin 16a engages in the groove of the respective tool jaw 14, the spring 19 pulls it into the form-fitting L-shaped receptacle.
  • a rotatable connection is made via a snap ring 20 arranged in ring grooves.
  • the push button 18 is secured against rotation by a pin 21 which engages in an elongated hole in the push button 18.
  • a longitudinal hole in the push button 18 is used to connect a tool, such as a screwdriver or Allen key, to a slot or hexagon socket of the nut 17.
  • the nut 17 can thus, if necessary, be screwed firmly against the hole attachment to the pull pin 16, so that the hook of the pull pin 16 and the groove of the tool jaw 14 connect the respective tool jaw firmly 14 can be produced with the base body 2 or the slide 3.
  • the nut 17 is to be loosened and then moved longitudinally via the push button 18, whereby the tool jaw 14 is released.
