Description

Gegenstand der Erfindung ist eine Werkstückspannvorrichtung für Werkzeugmaschinen, insbesondere Flächenschleifmaschinen, die erstmalig die Aufgabe verfolgt, die Werkstücke auf hydraulischem Wege aus der Aufnahmestellung in die Arbeitsstellung überzuführen, diese darin festzuhalten und dann in die Ausgangsstellung zurückzubringen. Eine Lösung wurde darin gefunden, daß ein Träger für die Spannvorrichtung durch ein hydraulisches Getriebe zu einer Kipp- oder Schwingbewegung veranlaßt wird, die indessen auch durch eine geradlinige Bewegung in Richtung der Drehachse des Werkzeuges ersetzt werden kann.The subject of the invention is a workpiece clamping device for machine tools, in particular surface grinding machines, which for the first time have the task of removing the workpieces hydraulically from the To transfer the recording position to the working position, to hold it in it and then return to the starting position. A solution was found in that a carrier for the clamping device through a hydraulic transmission to one Tilting or oscillating movement is caused, which, however, also by a straight line Movement in the direction of the axis of rotation of the tool can be replaced.

Gegenüber bekannten Vorrichtungen, die die Werkstücke auf mechanischem Wege einspannen, hat die hvdraulische Spannvorrichtung den wesentlichen Vorteil, daß sie mit einem einzigen Hebelgriff gleichzeitig sämtliche Spannmittel einzurücken und zu lösen gestattet. Dadurch wird ein erheblicher Zeitgewinn und eine Vereinfachung der Bedienung ohne Standwechsel des Bedienungsa5 marines erzielt und ein unsachgemäßes Spannen, namentlich ein Verspannen der Werkstücke infolge von Ungleichmäßigkeit in dem nacheinander erfolgenden Anziehen der einzelnen mechanisch betätigten Mittel, vermieden. Compared to known devices which clamp the workpieces mechanically, the hydraulic clamping device has the essential advantage that it allows all clamping means to be engaged and released simultaneously with a single lever handle. Thereby, a significant gain in time and simplification of the operation without prior exchange of the operation a marine 5 is achieved, and improper clamping, in particular a clamping the work pieces as a result of unevenness in the seriatim individual tightening of the mechanically actuated means avoided.

In der Zeichnung ist der Erfindungsgegenstand in einer Ausführung teils in Ansicht und Schnitt dargestellt.In the drawing, the subject matter of the invention is partly in view in one embodiment and section shown.

Auf dem Arbeitstisch 7 einer Flächenschleifmaschine befindet sich eine Grundplatte 31, an welcher ein das Werkstück 32 tragender Winkel 33 schwingbar gelagert ist. An dem Winkel 33 ist eine Spannvorrichtung 18 zum Festhalten des Werkstückes 32 mittels der Klaue 24 angebracht. Die Schwingbewegung wird durch einen im Preßzylinder 34 bewegten Kolben 35 und den Kurbeltrieb 36 ausgeführt. Der in der Arbeitsstellung gezeigte Winkel 33 hält das Werkstück 32 gegen das Schleifwerkzeug 5 in der durch einstellbare Anschläge 37 bestimmten Lage unter ständigem Preßdruck fest. Die Druckflüssigkeit wird aus einer an der Maschine befindlichen Pumpe zugeführt.A base plate is located on the work table 7 of a surface grinding machine 31, on which an angle 33 carrying the workpiece 32 is pivotably mounted. At the angle 33 is a clamping device 18 for holding the workpiece 32 by means the claw 24 attached. The oscillating movement is caused by a piston 35 moving in the press cylinder 34 and the crank mechanism 36 executed. The angle 33 shown in the working position holds the workpiece 32 against the grinding tool 5 in the position determined by adjustable stops 37 under constant pressure. The hydraulic fluid comes from one on the machine located pump supplied.
