Definitions

  • the invention relates to a multiple tensioner for clamping of multiple workpieces according to the preamble of claim 1.
  • the invention also relates to a tensioning tower with a plurality of such multiple tensioners.
  • a generic multiple clamp is known. This has a fixed to a base fixed jaw and a plurality of adjusting jaws, which contain a relative to the base body adjustable and positionable in a desired position adjusting jaw body and a sliding relative to the Verstellbackenanalysis jaw.
  • the adjusting jaw body are connected via a toothing with the base body.
  • a manually operable sliding element is arranged in the adjusting jaw body, which has a toothing for engagement in a corresponding counter-toothing on the inner sides of two spaced side cheeks of the main body.
  • the sliding element To implement the adjusting jaws, the sliding element must be raised from a lowered engagement position into an upper release position, the adjusting jaw body moved to a desired position, and the sliding element lowered again by engagement of the toothing.
  • the conversion of the clamping position is relatively time-consuming, since each adjusting jaw must be solved individually, adjusted and re-attached. Since the adjusting jaw bodies also serve as jaws for a subsequent clamping jaw, a correction of the clamping point points may be required after the shifting of the adjusting jaws.
  • the object of the invention is to provide a multiple tensioner of the type mentioned and a tension tower with several such multiple tensioners that allow a quick change of the clamping position without re-adjustment of the zero points.
  • a plurality of spaced-apart jaws with a fixed contact surface for the workpieces to be clamped are mounted on the body.
  • the fixed abutment surfaces can thus remain at a fixed position even with a change of the adjusting jaws, so that no readjustment of the zero points is required.
  • the adjusting jaws are fastened separately from the fixed jaws on a base rail adjustably arranged in the base body. A changeover of the adjusting jaws can thus take place without changing the fixed abutment surfaces, whereby a common quick adjustment of the adjusting jaws for pre-positioning is made possible by the base rail adjustably arranged in the base body.
  • the adjusting jaws By shifting the base rail, the adjusting jaws can be prepopulated in a simple manner powerless in the desired clamping position, the Schnellverstell- and work area is determined by the number of clamping points. By shifting the clamping jaws against the Verstellbacken redesignn then the actual voltage of the parts can be done. The fewer clamping points are selected, the larger parts can be tensioned.
  • the base slider for pre-positioning of the adjusting can be moved by a rotatably mounted within the body and axially secured adjusting spindle.
  • the adjusting spindle is suitably rotatably connected to an extension spindle.
  • the base slider is preferably designed such that it covers the longitudinal groove between the two side cheeks of the body as close as possible to the top. This encapsulated construction avoids open gaps where chips and other processing residues can penetrate.
  • the base slider relative to the upper bearing surfaces of the body is set back down. This results in the advantage that in the held by the multiple clamping workpieces and through holes without documents can be made. But the base slider can also be designed flush with the bearing surfaces of the body, so that only one guide plane is created and the geometry of the jaws is easier.
  • the adjustment of the clamping jaws can be carried out in a particularly effective and simple manner by a clamping wedge arranged between the clamping jaw and the adjusting jaw body.
  • the adjustment of the clamping jaws but can also be done hydraulically, pneumatically or in any other suitable manner.
  • the jaws do not need too much space, they are designed in plan view U-shaped and have a recess for receiving the adjusting jaws.
  • the adjusting jaws they can be retracted recess of the jaw, creating a compact design with the largest possible adjustment is possible.
  • FIG. 1 shows a multiple tensioner according to the invention in a perspective from the front
  • FIG. 2 shows the multiple vice of FIG. 1 in a perspective from behind
  • FIG. 3 shows a multiple vice in a side view
  • Figure 4 shows the multiple clamp of Figure 3 in a plan view with open
  • Figure 5 shows the multiple clamp of Figure 3 in a longitudinal section with closed
  • Fig. 6 is a sectional view taken along the line B-B of Fig. 4;
  • FIG. 7 is a sectional view taken along the line AA of Figure 3 and FIG. 8 shows a tensioning tower with a plurality of multiple tensioners.
  • the multiple tensioner shown schematically in Figures 1 and 2 in a perspective front and rear view comprises a rail-shaped base body 1, which is e.g. mounted on a machine table of a machine tool or can be attached to a base body 2 of a tension tower 3 shown in Figure 8 with a plurality of circumferentially distributed multiple tensioners.
  • the base body 1 is made in one piece and has a U-shaped cross section with two spaced-apart side walls 4 and 5.
  • the base body 1 may also consist of a base plate and two laterally bolted side cheeks 4 and 5.
  • the two side cheeks 4 and 5 could also be attached directly to the base body 2 of the tension tower 3 shown in Figure or formed on this.
  • a base jaw 6, a plurality of further in-line jaws 7 and a plurality of adjusting jaws 8 are arranged on the base body 1 on the base body 1.
  • the base jaw 6 is attached to one end of the main body 1 following a head plate 9 bolted thereto at the end.
  • the arranged in series festoons 7 are fixed by means of screws 10 and lower retaining webs 11 via predetermined recesses 12 and corresponding threaded holes 13 on the upper bearing surfaces 17 of the two side walls 4 and 5 of the base body 1.
  • a plurality of recesses 12 and threaded holes 13 may be provided so that the dies 7 can be implemented if necessary or optionally more or less jaws 7 can be mounted.
  • the adjusting jaws 8 are arranged on a between the side walls 4 and 5 in the longitudinal direction of the base body 1 slidably guided and adjustable in the longitudinal direction of base slide 15.
  • the base slider 15 is designed such that it covers a longitudinal groove 16 between the two side walls 4 and 5 of the main body 1 as close as possible to the top. As a result, an encapsulated construction without open column is reached, can penetrate the chips or other processing residues.
  • the base slider 15 is offset from the upper bearing surfaces 17 of the base body 1 down. This results in the advantage that in the workpieces held by the multiple vice and through holes can be made without documents. But the base slider 15 can also be flush with the support surfaces 17 on the side walls 4 and 5 of the main body 1 to be executed. This has the advantage that only one management level is created and the geometry of the jaws is very simple.
  • the base slide 15 is adjustable in the longitudinal direction by means of an axially secured and rotatably arranged adjusting spindle 18.
  • the adjusting spindle 18 is rotatably supported according to Figure 6 via an enlarged head 19 in the base body 1 attached to the top plate 8 and secured axially via a locking ring 20.
  • the adjusting spindle 18 has an external thread 21 for engagement in a corresponding internal thread 22 in the base slide 15.
  • the adjusting spindle 18 is non-rotatably connected to an extension spindle 23 which, according to FIG. 5, extends through the base body 1 up to the end opposite the top plate 8 through a bore 24 in an end plate 25 fastened to the end of the base slider 15.
