Definitions

  • the invention relates to a clamping unit according to the preamble of claim 1 for a modular clamping system, the workpieces with a complicated geometry, such as vehicle bodies and parts, holds and a method for adjusting a predetermined base length on the clamping unit.
  • the object of the invention is primarily to create a clamping unit for said clamping modular systems, in particular for receiving and holding workpieces with a complicated geometry, which enables a more cost-effective production of the individual parts and also a reduction in assembly time as well as a quick readjustment during production use when Users allowed.
  • Claim 8 shows a new method for cost-effective adjustment of a base length specified by the user in the manufacture of the clamping unit, as well as measures for reproducible fixing of the adjusted base length mentioned above.
  • the subordinate method claim 9 discloses further developments.
  • the basic concept shown in Fig. 1 of the new clamping unit S for a modular clamping system for receiving and holding workpieces W with a complicated geometry comprises a commercially available clamping part T having at least one clamping lever Ta and at least one of several, interchangeable and adjustable in height with respect to one another and interconnected components existing frame F, the means 7, 10 and 10 'are assigned for the continuous adjustment of its components with respect to a base length x which can be specified by the user of the clamping unit.
  • the frame F consists of a foot part 1, 101 or 102, a head part 8, 80 or 81 for holding the tensioning part T, a middle part 6, 60, 61 or 62 for connecting the foot part and the head part as well as the said adjusting means, which according to the invention ensure a continuous adjustment of the components or base length x on the one hand and at least towards the head part 8, 80 or 81 and on the other hand in the lower region of the frame F to the respective middle part 6, 60 or 61.
  • each clamping unit S can be pre-adjusted by the manufacturer and the user only has to make a 'fine' readjustment.
  • Another advantage is the extremely short response time to manufacturing tolerance deviations.
  • FIGS. 2 and 3 show the frame F of the clamping unit S from FIG. 1 in section; the middle part 6 is here preferably made of a material with a box-shaped cross section.
  • the use of solid material with a corresponding cross section or the manufacture of the middle part 6 as a burning part is also economical.
  • FIGS. 5 to 11a further developments and embodiments of the invention are shown, which are explained in more detail below.
  • FIG. 5 and 5a show, in two different views, in an embodiment of the basic idea, a third middle part 61 which, with a generally aspiring shape, one or more times in the longitudinal direction with the formation of angles ⁇ and / or ⁇ , through two adjacent legs 61a, 61b or 61c, is angled.
  • the middle part 60 there consists of a lower 60a and an upper 60b plate-shaped strip, the two strips 60a and 60b each abutting one another with a surface and connected with the inclusion of a rotary bearing 60c.
  • the pivot bearing preferably consists of an axially secured bolt.
  • FIGS. 7 and 7a A modification of the foot part is also shown in FIGS. 7 and 7a.
  • the vertical leg 101b of the second foot part laterally engages the horizontal leg 101a to form an L-shape.
  • FIG. 8 shows a fourth middle part 62 as a further design option for the middle part.
  • a lower 62a and an upper 62b rod-shaped section form here, connected by an articulation point 62c, the central part 62.
  • the articulation point 62c designed as a screw connection can be chosen at any point, the length of the sections 62a and 62b being chosen accordingly.
  • a further possible embodiment variant according to FIG. 9 still consists in arranging the head part and foot part directly next to one another.
  • a third foot part 102 is provided.
  • the horizontal leg 102a and the vertical leg 102b form an L-shape.
  • the vertical leg 102b is equipped at the top with a flat surface 102c for the height adjuster 10 or 10 ′ and with two threaded bores 102d for the engagement of the bolts 5.
  • FIGS. 10, 11 and 11a now show two configurations of the head part.
  • the vertical leg 80a is slidably supported on the middle part 6; Tuning plates serve as height adjusters 10 '.
  • the horizontal leg 80b receives the tensioning part T arranged horizontally.
  • the third head part 81 shown in FIGS. 11 and 11a comprises a base part 81a with a downwardly directed vertical leg 81b for connection to a central part 6.
  • a holder 81c for receiving a fixing pin 81e is fastened to the base part 81a with a pivot axis 81d.
  • the new clamping unit S shown above is well suited for the implementation of the task, in particular for variable use.
  • the presented clamping unit S in all its variants, can also be used in particular to carry out the new method for adjusting a basic length x.
  • this method by actuating the lower height adjuster 7, the base length x located between a set-up surface 1d of the foot part 1 and a support surface 8d provided on the horizontal leg 8b of the head part 8 is set to the user-specified length Measure adjusted by the manufacturer, then the threaded bolts 5 located in the vertical leg of the foot part are firmly tightened and then the respective washer 4 is fixed to the outer wall of the vertical leg 1b by applying welding spots 4 '.
  • Said method steps can also be used analogously when fastening the foot part 1 of the clamping unit S to a base plate G or when the base length x is readjusted by the user with the upper height adjuster 10.
