To clamp workpieces, clamps designed as screw clamps have been used so far

which a screw spindle with Druckütück the work;

piece ge, ~ en a fixed clamping part clamps

The invention relates to a Einapannzwinse with peatarm and translation arm and is DAT last he wears a Drucketück which by a piston rod of a Mediaeval in a cylinder by pressure medium moving \ piston is movable. To no reversing device

to need the pressure medium, the piston is purposeful- '

moderately from its starting position against the effect;

moved by a spring so strong that it

Opening of the pressure means cylinder space oa the piston in

a starting position for UokdrUokt. A control valve i

enables the pressure medium inlet, the pressure medium system

to control the linder room and the pressure medium outlet in such a way that ■ ·

that an inlet opening j

voltage for a pressure medium to act on the piston j

opened and its exit opening closed as well for returning the piston.; * and retracting the piston

rod, the pressure medium inlet opening is closed by a spring and the outlet opening for the pressure medium to exit the cylinder is opened, and there is still a gap in which the channel to the pressure medium cylinder space is closed so that also The clamp exerts a holding effect without permanent DruckmlttelanachluB.Dor the advancing arm of the inventive pressure medium, e.g. Preaaluftzwlnge can be ring-shaped to accommodate the cylinder at its free base and to attach the cylinder to a ring groove to accommodate one on the cylinder collar Screws on the cylinder cover screwed on the cylinder arm, the cylinder is held on the terochromic arm and, apart from the opening for the piston rods, var3chlo3-een · The advantages of the inventive locking winch ! can be seen in the fact that the clamping and unclamping of workpieces takes place in a very short time and is adjustable with a tight fit and that workpieces break in clamps whose tightening force is imprecise or that the workpiece is prevented from loosening in the clamp display the mandatory pressure and release the excess pressure after setting.

In the following the invention is based on only one Ausfilhrungsbeispiel illustrative drawing explained; show it s

The Preßluftzwir.ga shown on the drawing consists of the slide 1 with _? estarm 2 guided by the slide rail 1aa yerachieboarm 5, which carries a footing 4 with a hanging groove 5 · In the ^ ing 4 a cylinder 6 is attached, the cylinder collar. 3 7 engaging in the ping groove 5. Eia ZJ- Iinderdeckel9 is screwed to the sliding arm 3 by means of screws 8. In the Z / linder 6, the piston 10 with the sleeve 11 and piston rod 12 can be moved χ the piston rod 12 is guided through the cylinder cover 9 and has a pressure piece that can move within limits at its free end 13 · The piston 10 is located in accordance with FIG. 1 by the action of the veder

14 in its starting position To operate the compressed air clamp, the same is connected to a pressure medium line via the smart nipple 15 of the control valve 16 arranged on the cylinder 6, the pressure medium being applied to the piston 10 through the inlet opening 17, the valve channel 18 and the channel 19 and against the pressure the spring 14 moves the piston in the cylinder, so that the piston rod 12 from dom cylinder moves out towards the arm 2 and a workpiece between χηα. 2 and pressure piece 13 clamped · The further pressure medium supply or a pressure medium discharge line ψ + λ can be locked from the cylinder by means of a setting valve.

To release the clamp, the valve plate 21 is moved downwards by pressing the Vontilknopf 20 so that the inlet opening 17 for the pressure medium is closed and the outlet opening 22 is released that the peder 14 can move the piston 10 back into its starting position. The pressure medium in the cylinder passes through duct 19 and valve chamber 18 through outlet opening 22 and bores 23 ± m valve
