Definitions

  • the present invention relates to a cleat clamp and a method of fixing a workpiece to support means with crampons tacklers.
  • tackle studs are members for fixing a workpiece to support means such than a table or a pallet.
  • Each tacking clamp is adapted to be fixed on the means of support and to come into abutment against the workpiece, thus ensuring the blocking of the latter.
  • the object of the present invention is in particular to resolve this drawback.
  • a tacking crampon of the type comprising a body intended to be fixed on the support means and to come in support against a workpiece, remarkable in that it comprises at least one tip, means for striking said tip against said piece so as to make penetrate this point into this part, and means for maintaining said point pressed inside said part.
  • the point can penetrate and remain pressed in the interior of the workpiece, thus ensuring that this workpiece is blocked with a extreme stability on the support means.
  • FIG. 1 in which there is shown a part to machine such as a sheet 1 placed on support means such as a table 3.
  • a plurality of tacking studs CF1 to CF3 and CM1 to CM3 according to the invention make it possible to fix the sheet 1 on the table 3 with a view to its machining by appropriate means (milling machine, drill, sander, ).
  • the tackle studs according to the invention are of two types: fixed (CF1 to CF3) or mobile (CM1 to CM3).
  • the CF crampon includes a body 11 produced for example by machining or machined molding of a metal alloy, this body being substantially symmetrical with respect to a plane P.
  • the body 11 is crossed by a bore 13 whose axis is contained in the plane P.
  • Housing 15a, 15b are formed in the body 11 symmetrically with respect to plane P.
  • Bores 17a and 19a whose axes coincide and parallel to the plane P, open into the housing 15a on the one hand and outside the body 11 on the other go.
  • Similar bores 17b, 19b are arranged symmetrically by compared to plan P.
  • the body 11 In the region 21 intended to come into abutment against the workpiece, the body 11 has a projection provided with a non-slip surface formed for example by streaks 23.
  • the means for blocking the workpiece 1 includes a rod 29 slidably mounted inside the body 11 and ending with a point 5.
  • This rod is preferably formed from specially treated steel, and the point 5 preferably has three sides.
  • the locking means of the part 1 also include a screw 31 independent of rod 29.
  • the screw 31 is arranged in the bore 17a (see FIG. 3) in the extension axial of the rod 29.
  • the screw 31 is slidably mounted inside the bore 17a, and it has a thread 33 engaged with a nut 35 disposed inside the housing 15a.
  • the geometry of the nut 35 is such that it can slide freely inside of the housing 15a in the axial direction of the screw 31, while being locked in rotation inside this accommodation.
  • a pin 37 prevents the screw 31 from coming out of the nut 35.
  • This slight angle ⁇ is preferably 1 ° 30 '.
  • FIGS. 7 to 9 in which a mobile type CM crampon according to the invention.
  • the movable tackle clamp CM in fact comprises a main part 11 intended to bear against the workpiece and a secondary part 39 intended to be fixed on the table 3.
  • main parts 11 and secondary 39 include complementary racks 41, 43.
  • the secondary part 39 is crossed in the area of its rack 43 by a substantially circular hole 47 whose diameter is substantially equal to the width of the oblong hole 45.
  • the heads of the screws 31 are then struck mobile spikes CM1 to CM3.
  • the screws 31 are turned at using a suitable tool (electric screwdriver or other), which has the effect of being given that the nuts 35 are fixed in rotation, to bring the screws into a position (see Figure 6) where they keep the rods 29 pressed against the part 1.
  • a suitable tool electric screwdriver or other
  • the tacking studs according to the invention can have a low height, in particular less than the thickness of the part to be machine, which makes it easy to machine this part, particularly in the vicinity of its edges, especially in the case of a sanding operation ...
