Definitions
- the invention relates to a hydraulically operated Clamping force holding element for clamping devices for clamping Workpieces on tables, fixtures or pallets, where a Clamping pin is guided in a housing, which is transversely through a Direction of action of the clamping bolt arranged clamping force holding element is fixable in that the clamping bolt in its lower area Wedge surfaces is provided that slide on the wedge-shaped Piston rod of an actuating piston are guided.
- a clamping device for clamping workpieces is known (EP 0 620 084), in which a clamping head slides on an inclined plane is that the frictional forces in this plane are greater than that on the Clamping forces.
- the inclined plane is formed between the lower part of the clamping head merging into a plunger and the Piston rod one arranged transversely to the direction of action of the clamping head Tension holding element.
- a keyway is made in the wedge surface of the piston rod and the ram with wedge bevels. The wedge slants slide in the Keyway.
- the clamping technology goes over to smaller, highly effective clamping elements compact construction. It is therefore the object of the invention once to integrate the two hydraulic systems in one system and the other To design elements of this one hydraulic system so that the clamping bolt is self-locking in its working position without any signs of settlement.
- the advantage is a compact construction, which is easy in all circumstances the clamping technology can be adjusted.
- a bore 3 is made in the housing 1, in which the Clamping pin 2 is slidably guided.
- a blind hole 4 is provided in the housing 1, which 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 Sloping slope.
- This key surface 8 is a keyway 9 let in.
- This keyway 9 runs parallel to the key surface 8 with const. Depth. In its lower area, where the two flanks of the keyway 9 are pointed To run at an angle to each other is a bore 10 along the keyway 9 introduced so that an open gap 11th between the keyway base and the bore arises.
- the two flanks of the keyway 9 form with the open bore a track.
- This guideway is in such an area via the holding piston 5 led that the clamping process is executable.
- the holding piston 5 is through Actuation of the pressure chamber 12 moved into its clamping position and by acting on the pressure chamber 13 in its starting position pulled back.
- the clamping bolt 2 is in its lower area with the holding piston Wedge surfaces 14 provided, the slope of which is exactly the slope of the keyway 9th is adjusted. However, the wedge surfaces 14 do not end in a point, 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 a in the lower area from the wedge surfaces 14 and the cam 15 formed wedge-shaped guide piece. This guide piece can be inserted into the guideway and slides in it in the crooked form Level.
- the holding piston 5 is in its lower region with a flat 16 Mistake.
- This flattening 16 is open to the pressure chamber 13.
- To the Pressure chamber 12 it ends shortly before the seal 17.
- This forms the Holding piston left and right of the seal 17 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 area of the flattened area 16 there is a slight play between the piston rings 18, 19 and Inner wall of the cylinder formed by the blind bore 4. This game is required to ensure that the holding piston is attached to the Flattening 16 formed edges 25,26 on the inner wall of the cylinder can support.
- the mode of action is as follows: Pressure is introduced into the pressure chamber 12 for tensioning.
- the holding piston 5 moves to the right and pushes its wedge bevel 8 under the clamping bolt 2 along.
- the clamping bolt 2 slides with its guide piece in the guideway and is thus guided upwards out of the housing 1.
- the system is fixed in that the holding piston 5 is supported with the edges 25, 26 of the flat 16 on the wall of the cylinder and the clamping bolt 2 presses with its wedge surfaces 14 onto the flanks of the keyway 9.
- Retroactive forces that arise during machining of the workpiece have no influence on the clamping bolt, even if the hydraulics fail - for whatever reason - because self-locking due to surface pressure on the wedge surfaces 14 and the edges 25, 26 of the flattening 16 arises, which prevents retraction of the holding piston 5.
- the pressure chamber 13 is acted upon to relax.
- the hydraulics will for this purpose applied to the hydraulic connection 20 and via line 21 in the Pressure chamber 13 out.
- Which is in the pressure chamber 13, in the keyway 9 and in the bore 10 building pressure causes the holding piston 5 in its starting position is returned and at the same time the clamping bolt 2 with his Guide piece is raised in the guideway and thus loosens, so that he slides in the track.
- the clamping bolt is thus in the Housing retracted.
- This Holding piston can also be made from two parts. The separation of the two Parts lies in the plane between the two piston rings 18, 19 with the intermediate seal 17 and the piston rod.
- the piston rings with The central gasket are made as one piece and are over equipped the diameter with a dovetail 23.
- the counterpart is made of the piston rod with the bevel 8 and the keyway 9 and the guideway and is provided with a dovetail groove 24 into which the piston ring piece is insertable.

Abstract
Description
- Fig. 1
- zeigt die Spannvorrichtung im entspannten Zustand
- Fig. 2
- zeigt die Spannvorrichtung im gespannten Zustand
- Fig. 3
- zeigt das Ineinandergreifen der keilförmigen Elemente
- Fig. 4
- zeigt den Haltekolben
Zum Spannen wird Druck in den Druckraum 12 eingeleitet. Der Haltekolben 5 bewegt sich nach rechts und schiebt dabei seine Keilschräge 8 unter den Spannbolzen 2 entlang. Der Spannbolzen 2 gleitet mit seinem Führungsstück in der Führungsbahn und wird damit nach oben aus dem Gehäuse 1 heraus geführt. Sobald der Spannbolzen an dem Werkstück anliegt, setzt sich das System fest, indem sich der Haltekolben 5 mit den Kanten 25,26 der Abflachung 16 an der Wandung des Zylinders abstützt und der Spannbolzen 2 mit seinen Keilflächen 14 auf die Flanken der Keilnut 9 drückt. Durch die Abstützung des Haltekolbens 5 mit den Kanten 25,26 der Abflachung 16 an der Zylinderwandung entsteht zwischen Spannbolzen und Haltekolben ein in sich starres Gebilde frei von jeder Setzerscheinung. Rückwirkende Kräfte, die bei der Bearbeitung des Werkstückes entstehen, haben keinen Einfluß auf den Spannbolzen, auch dann nicht, wenn die Hydraulik - gleich aus welchen Gründen - ausfällt, da durch Flächenpressung an den Keilflächen 14 und den Kanten 25,26 der Abflachung 16 Selbsthemmung entsteht, die ein Zurückweichen des Haltekolbens 5 verhindert.
