Definitions

  • the present invention relates to a clamping block for clamping workpieces or tools according to the preamble of claim 1 in a reproducibly precise alignment with respect to an object in the form of a tool or a workpiece.
  • clamping devices for clamping workpieces or tools, which are designed either for general or individual clamping tasks and accordingly have clamping jaws that are parallel-clamping or aligned with the object to be held. It is customary to make one of them fixed in the case of parallel clamping jaws and to make the second movable practically in the same plane by actuating the spindle or lever.
  • circular clamping devices such as Drill chucks or rotary tongs are known to have individually movable clamping jaws, which can be moved along a wedge surface and are urged concentrically against the object to be held in clamping engagement. It is advantageous that large clamping forces can be generated in a compact arrangement by a suitable choice of the wedge angle and that a workpiece or tool can be securely clamped with a relatively low actuating force.
  • the object of the invention is to provide a clamping block that is particularly suitable for flat workpieces or tools with parallel clamping areas, which can be placed on a spindle, a piston, a plate, etc., is provided with a fixed jaw and a movable jaw, the latter along complementary inclined or wedge surfaces is movable and by means of a Spindle or screw is tightened against the fixed jaw.
  • the advantages of the clamping block according to the invention are, in particular, simple, precisely manufactured clamping parts and a relatively large clamping area. Due to the downward force component when tightening the movable jaw, the clamping object is automatically pulled against a lower stop surface, whereby precise, reproducible clamping can be achieved.
  • the block base 1 of approximately L-shaped configuration with two legs 1.1, 1.2 of approximately the same length contains on its chest side the clamping surface 2 of a fixed clamping jaw 3, which is expediently designed in one piece with the block base 1.
  • a nose-projecting support section 4 At the block-side (inner) end of the clamping surface 2 there is a nose-projecting support section 4, which section has a stop surface 4.1 standing at right angles to the clamping surface 2, which can be used as a clamping depth reference surface when clamping a workpiece or a tool.
  • the support section 4 further contains a control or wedge surface 4.2 at an angle ⁇ of 40 to 60 ° to the axis of movement of a clamping screw 6 for transverse guidance of a movable clamping jaw 5, which by means of the clamping screw 6 (or a spindle) against an object 7 to be clamped in the clamping block can be pressed.
  • the main surfaces on the movable clamping jaw 5 are the clamping surface 5.1 protruding over a plate zone 5.3, which, like the clamping surface 2 on the fixed clamping jaw 3, can be provided with transverse corrugation or another surface structure which increases the grip, and one on a projection 5.4 on the plate zone 5.3 formed wedge surface 5.2, the inclination of which is complementary to the control or wedge surface 4.2 on the support section 4.
  • the idle state of the movable clamping jaw 5 it is in an equilibrium position, which is defined by first and second spring elements 10 and 11 and the clamping screw 6 inserted on the supporting section 4.
  • the spring elements 10 and 11 for example in spring housings on a table-shaped section 8 of the block base 1 and on the projecting support section 4, helical springs are at right angles to one another and, for the movable clamping jaw 5 with the clamping screw 6 loosened, result in a “floating” bearing above the table-shaped section 8 the Block base 1.
  • By appropriate dimensioning of the spring elements 10, 11 it can be achieved that when the screw 6 is loosened, the movable clamping jaw 5 adjusts practically parallel to the fixed clamping jaw 3.
  • the latter is centered in the transverse direction by a bolt 9, which is seated in the table-shaped section 8 and which engages in a slot 12 leading to the side in the movable clamping jaw 5.
  • the movable clamping jaw 5 When the screw 6 is tightened, the movable clamping jaw 5, which is lifted from the table-shaped section 8 by the first spring elements 10, is first brought into contact either with the object 7 to be clamped or with the wedge surface 4.2 against the pressure of the second spring elements 11.
  • the pendulum movement occurring on the movable clamping jaw 5 is possible by means of a screw recess 13 designed thereon as an elongated hole.
  • the movable clamping jaw 5 lies completely against both the object 7 and the wedge surface 4.2.
  • the movable clamping jaw 5 moves parallel to the fixed clamping jaw 3 against the table-shaped section 8, so that the object 7 is correctly clamped in parallel.
  • the standing surface 14, which can be up, down or to the side, depending on the position of use of the terminal block, can be provided with centering means (not shown) such as fitting bolts, fitting bores, templates etc., and clamping elements. This means that when using the clamping block as a clamping device for exchange tools or a carrier for tools with part machining tasks, a quick and precise, reproducible exchange can take place.
