Definitions

  • the invention relates to a Clamping device for clamping of Workpieces on tables, devices or pallets, according to the preamble of claim 1.
  • fixtures or pallets When clamping workpieces on tables, fixtures or pallets must be sure that the workpieces in the tensioned state so are fixed that during the period of processing on them acting forces do not reduce the clamping force.
  • the clamping technology is changing to smaller, highly effective clamping elements in to use crowded construction. It is thus an object of the invention once to integrate the two hydraulic systems in one system and the other Make elements of this hydraulic system so that the clamping bolt is self-locking set in its working position without settling.
  • the advantage is a compact design that easily accommodates all circumstances can adjust the clamping technology.
  • a bore 3 is introduced in the housing 1, in which the Clamping bolt 2 is slidably guided. Transverse to the direction of movement of Clamping bolt 2 is a blind bore 4 is provided in the housing 1, the Cylinder for the holding piston 5 forms.
  • This holding piston 5 is a double acting piston, between the two piston surfaces 6,7, the piston rod is provided with a wedge surface 8.
  • This wedge surface 8 forms an in Clamping slope sloping slope.
  • this wedge surface 8 is a keyway. 9 admitted.
  • This keyway 9 extends parallel to the wedge surface 8 with const. Depth. In its lower area, where the two flanks of the keyway 9 in an acute Angle to run on each other is a bore 10 along the keyway. 9 introduced so that between Keilnutground and bore an open gap 11th arises.
  • the two flanks of the keyway 9 form with the open bore a guideway.
  • This guideway is in such an area on the holding piston. 5 guided that the clamping operation is executable.
  • the holding piston 5 is through Actuation of the pressure chamber 12 is moved to its clamping position and by acting on the pressure chamber 13 in its starting position scaled back.
  • the clamping bolt 2 is in its lower part to the holding piston out with Wedge surfaces 14 provided whose slope exactly the slope of the keyway. 9 is adapted.
  • the wedge surfaces 14 are not pointed, but end in a cam 15.
  • This cam 15 corresponds in diameter the inner diameter of the bore 10.
  • the cam 15 is in the lower part flattened so that its cross-section does not quite correspond to the semicircle.
  • the Clamping pin 2 thus forms in the lower part of the wedge surfaces 14 and the cam 15 formed wedge-shaped guide piece. This guide piece is inserted into the guideway and slides in it in the formed crooked Level.
  • the holding piston 5 is in its lower region with a flat 16th Mistake.
  • This flattening 16 is open to the pressure chamber 13.
  • To the Pressure chamber 12 towards it ends just before the seal 17th two piston rings 18, 19.
  • the Diameter of these piston rings 18,19 is slightly smaller than that Diameter of the holding piston 5 in the region of the flat 16. This results a slight play between the piston rings 18, 19 and the Inner wall of the cylinder formed by the blind bore 4. This game is required to achieve that the holding piston with his on the Flattening 16 edges 25,26 formed on the inner wall of the cylinder can support.
  • the mode of action is the following: For clamping pressure in the pressure chamber 12 is initiated.
  • the holding piston 5 moves to the right and pushes its wedge slope 8 under the clamping bolt 2 along.
  • the clamping bolt 2 slides with its guide piece in the guideway and is thus guided up out of the housing 1 out.
  • the system is fixed by the holding piston 5 is supported with the edges 25,26 of the flattening 16 on the wall of the cylinder and the clamping bolt 2 surfaces with its wedge 14 presses on the flanks of the keyway 9 ,
  • By supporting the retaining piston 5 with the edges 25,26 of the flattening 16 on the cylinder wall is formed between clamping bolt and retaining piston in a rigid structure free of any settling phenomenon.
  • FIG. 4 another example of the invention is shown. So far the Holding piston 5 described as a one-piece whole.
  • This Holding piston can also be made of two parts. The separation of the two Parts lies in the plane between the two piston rings 18,19 with the intermediate gasket 17 and the piston rod.
  • the piston rings with The centrally located seal are manufactured as one piece and are over the diameter equipped with a dovetail 23.
  • the counterpart is made of the piston rod with the wedge slope 8 and the keyway 9 and the guideway and is provided with a dovetail groove 24 in the the piston ring piece can be inserted.
