Definitions

  • the present invention relates to a quick-clamping device according to the preamble of claim 1, for clamping workpieces, preferably of the same shape, during their processing.
  • Quick clamping devices for clamping workpieces are known in many embodiments.
  • clamping devices working with toggle lever arrangements in which the workpiece is pressed into a fixing position against a receiving device by a pressure member on the shorter arm of the lever arrangement.
  • Claw clamping devices are also known, which are provided with screw or spindle clamping elements for generating pressure.
  • eccentric clamping devices on the market in which the eccentric acts either directly or via a pressure element on the workpiece and ensures its stable mounting.
  • clamping or clamping system is usually designed so that according to clamping criteria, e.g. A distinction must be made between round or block clamping surfaces on the workpiece in order to determine the most suitable type of device for a given machining task.
  • the object of the present invention is to create a quick-action clamping device designed according to the principle of a vice with a short clamping distance and a preselectable clamping range, which device has one fixed jaw compared to one or two fixed jaws Has starting position bringable clamping block.
  • This clamping block should be able to be attached to a workpiece in a clamping position by means of a simple actuating member from the starting position mentioned.
  • Several such quick-action clamping devices should be able to be assembled into groups and can be used as multiple tools for simultaneous or sequential machining of the same or different workpieces.
  • the clamping block which is provided with an eccentric part and can be brought into and out of clamping engagement with one of the fixed jaws, can be fixed at any point in its adjustment range by a simple locking means, and furthermore the clamping jaw can be brought into a reproducible retracting position by a short actuation movement, in which the Workpiece can be easily inserted into and removed from the clamping device.
  • the quick-action clamping device contains a base part 1 with two fixed jaws 3, which are preferably attached in one piece to a yoke plate 2 and are each provided with a mounting hole 4 explained later.
  • the yoke plate 2 contains laterally open clamping grooves 5 for clamping the base part 1 on a possible base plate or a machine table, and a longitudinally running guide slot 6 for the longitudinally displaceable receiving of a clamping block 7, of which essentially only the clamping head 8 is visible. At least one of the end faces 9 of the clamping head 8 is designed as a clamping surface.
  • the clamping block 7 is described in detail below with reference to FIGS. 2 and 4a, b.
  • the clamping block denoted overall by 7, containing a slide part 11 with a guide ruler 12 and 12 located underneath a T-fitting 13 of a coulisse guide formed over it.
  • the clamping head 8 contains the counterpart of the coulisse guide mentioned in the form of a T-groove 14 matched to the T-fitting 13, which in the assembled state of the clamping block 7 (FIG. 6) of this T- Adjusts the fitting lengthways and essentially free of play.
  • the T-slot 14 in the clamping head 8 is designed to be closed on the eccentric side and, in order to facilitate or enable the slot machining, is appropriately closed with a strip 10 attached by screw fastening.
  • the guide ruler 12 is mounted in the installed state of the clamping block 7 in the guide slot 6 with a sliding seat in order to ensure an exact longitudinal movement of the clamping block 7 in the base part 1.
  • a fitting member in the form of a fitting sleeve 15 is also shown, whose or its shaft for centering and fastening a single or several clamping units on an individually configurable (schematically shown) mounting plate 16, the mounting hole 4 is to be enforced in the fixed jaws 3 and its lower end engages in a centering seat 17 of this platen.
  • the fitting sleeve 15 has a head portion 18 with a larger diameter with a head opening 18.1 which enables the head of an Allen screw 20 to be received.
  • the head shoulder 18.2 comes to rest on the top of the cheek 3.
  • the clamping unit is fastened to the base plate 16 by means of the Allen screws 20 engaging in threaded bores 19 of the clamping plate 16, which penetrate the sleeve bore 21 with sufficient play and whose heads are countersunk in the head section 18 of the fitting sleeve.
  • the guide cylinder 23 of the eccentric part 22 is mounted in a vertical bore 25 of the slide part 11 so that it can rotate substantially without play and extends practically over its entire length inside the slide part.
  • the eccentric cam 24 with an eccentricity of 0.5-2 mm, depending on the desired clamping force and the intended clamping path, engages in an eccentric nut 26 (FIG.
  • the eccentric part 22 is provided with a polygon recess 28, e.g. a hexagon hole for receiving an Allen key, which can be inserted via an opening 29 in the surface of the clamping head 8 as an actuating tool for the eccentric part 22.
  • the slide plate 30 contains two longitudinal sections divided by transverse weakening grooves 32, namely a mounting section 33, on which the slide plate 30 is screwed to the bottom view of the guide ruler 12 by two Allen screws 35 so that the clamping block 7 is essentially free of play between the fixed jaws 3 Base part can be moved.
  • the second longitudinal section of the slide plate 30 is a clamping section 34, which is provided with a threaded bore 35 for receiving an Allen screw 36, the head 36.1 of which with sufficient play for the clamping movement (arrow A) of the clamping head 8 through its recess 37 against the top of the T-fitting 13 on the slide part 11 is tightenable.
  • the clamping section 34 is tightened against the bottom 31.1 of the groove 31 and the base shoulder 13.1 of the T-fitting 13 against the top 2.2 of the yoke plate 2.
  • the clamping section 34 of the slide plate 30 is elastically deformed and the clamping block 7 is rigidly connected to the base part 1.
  • the clamping head 8, controlled by the eccentric part 22, remains longitudinally movable.
  • the clamping block 7 or the clamping head 8 can be brought to any points (arrows C in FIGS. 1 and 6) between the jaws 3, in particular to the insertion and removal points of workpieces, and fixed there.
  • the eccentric part 22 By actuating the eccentric part 22 with a plug-in tool, the clamping of the workpiece is then initiated and released again.
