Abstract

The invention relates to a screwdriver operated by remote control, with handle, driver rod and hexagon ball head. Hexagon socket head cap screws for mounting or fastening instruments or the like are used in hot cells and possibly also in glove boxes for working radioactive or toxic material. The object of the invention is to provide a screwdriver which enables a hexagon socket head cap screw to be taken to its tapped hole by means of a manipulator in as simple and as reliable a manner as possible and then enables it to be screwed in, as far as possible without force, or enables the reverse sequence to be followed. The solution is characterised by a flexible ring, arranged in a groove in the equatorial area of the hexagon ball head and projecting beyond the ball surface, and by an articulated fastening of the driver rod in the handle.

Description

Fernbedienbarer SchraubendreherRemote-controlled screwdriver

Beschreibung: Die Erfindung betrifft einen fernbedienbaren Schraubendreher mit Griff, Dreherstab und Sechskantkugelkopf.Description: The invention relates to a remotely controllable screwdriver with handle, leno bar and hexagonal ball head.

In heißen Zellentund u.U. auch auf automatischen Montagestraßen, für die Bearbeitung von radioaktivem oder toxischem Material oder für automatische Montagevorgänge werden Schrauben mit Innensechskant zur Halterung bzw. Befestigung von Geräten oder dgl. verwendet. Ihre Manipulation erfolgt über Schraubendreher mittels fernbedienter Greifer, wodurch sowohl ihre Aufnahme als auch ihr Ansetzen an die Schraubenbohrung und das Schrauben selber äußerstes Geschick vom Bedienungspersonal erfordert. Dennoch gelingt es nicht immer, Schrauben in ihre Gewindebohrungen einwandfrei einzudrehen Bemühungen, diese Schwierigkeiten zu verringern, konzentrierten sich bisher auf eine Formanpassung der Griffe an die Zangen der Manipulatoren.In hot cells and possibly also on automatic assembly lines for the processing of radioactive or toxic material or for automatic assembly processes are screws with hexagon socket for holding or fastening devices or Like. Used. They are manipulated using a screwdriver using a remote control Grippers, which means that they are both received and attached to the screw hole and the screwing itself requires extreme skill from the operator. Yet It is not always possible to screw screws into their threaded holes properly Efforts to alleviate these difficulties have so far focused on adapting the shape of the handles to the tongs of the manipulators.

Die Aufgabe der Erfindung besteht darin, einen Schraubendreher zu bieten, der es erlaubt, eine Zylinderschraube mit Innensechskant mittels eines Manipulators auf einem möglichst einfachen und sicheren Weg zu seinem Gewindeloch zu bringen und sie dann möglichst gewaltlos einzudrehen bzw. in umgekehrter Reihenfolge vorzugehen.The object of the invention is to provide a screwdriver offer, which allows a socket head screw by means of a manipulator to bring it to its threaded hole in the simplest and most secure way possible and then screw them in as non-violently as possible or proceed in reverse order.

Die Lösung ist in den kennzeichnenden Merkmalen des Anspruches 1 beschrieben. Die Ansprüche 2 und 3 geben vorteilhafte Weiterbildungen der Erfindung wieder.The solution is in the distinguishing features of the Claim 1 described. Claims 2 and 3 give advantageous developments of the invention again.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels mittels der Fig. 1 und 2 näher erläutert.The invention is illustrated below using an exemplary embodiment explained in more detail by means of FIGS.

Die Fig. 1 zeigt eine Ansicht des Schraubendrehers mit Drehstab 1, Sechskantkugelkopf 7 und Griff 8, wobei der Griffkörper 4 im Schnitt dargestellt ist.Fig. 1 shows a view of the screwdriver with torsion bar 1, Hexagon ball head 7 and handle 8, the handle body 4 shown in section is.

Der Sechskantkugelkopf 7 weist im Bereich seines Äquators eine umlaufende Nut 9 auf, in der ein weichelastischer O-Ring 2 angeordnet ist. Der O-Ring 2 steht etwas über die Oberfläche des Sechskantkugelkopfes 7 hinaus, so daß er beim Einstecken in die Sechskantbohrung lo einer Zylinderschraube 11 an der Sechskantbohrungsinnenfläche haftet. Hierdurch bleibt die Zylinderschraube 1i auf dem Sechskantkugelkopf 7 nahezu gelenkig sitzen bis sie in ihrer Gewindebohrung eingesetzt ist.The hexagonal ball head 7 has a circumferential in the area of its equator Groove 9 in which a flexible O-ring 2 is arranged. The O-ring 2 is in place something beyond the surface of the hexagonal ball head 7, so that when you insert it into the hexagon hole lo of a cylinder screw 11 on the hexagon hole inner surface adheres. As a result, the cylinder screw 1i remains almost on the hexagonal ball head 7 sit articulately until it is inserted into its threaded hole.

Der Griff weist eine Würfelform und an allen 8 Ecken der beiden Stirnflächen Vorsprünge 12 am Griffkörper 4 auf, die ein Anfassen des Griffes 8 mittels der Greifer (nicht dargestellt) eines Manipulators erleichtern und gegen Ausrutschen der Greifer wirken.The handle has a cube shape and on all 8 corners of the two end faces Projections 12 on the handle body 4, which enable the handle 8 to be grasped by means of the gripper (not shown) facilitate a manipulator and prevent the gripper from slipping works.

Der Griff 8 selbst besitzt eine nach außen sich konisch erweiternde Ausnehmung 13, in der der Drehstab 1 federnd gelagert und gehaltert ist. Der Drehstab 1 ist mit einer zylindrischen Spiralfeder 5 auf seiner einen Seite 19 fest verbunden,während die andere Federseite 14 mittels Schraube 3 und Gewindestift 17 am Griffkörper 4 befestigt ist. Die Befestigung des Drehstabes 1 an der Spiralfeder 5 erfolgt über eine Ringplatte 6, welche sowohl mit dem Drehstab 1 als auch mit der Feder verschweißt ist. Die Schraube 3 ist ebenfalls mit der Spiralfeder 5 verschweißt. Der Gewindestift 17 dient der Drehsicherung der Schraube 3.The handle 8 itself has a conically widening outward Recess 13 in which the torsion bar 1 is resiliently mounted and held. The torsion bar 1 is with a cylindrical coil spring 5 on its one side 19 firmly connected, while the other spring side 14 by means of screw 3 and threaded pin 17 is attached to the handle body 4. The attachment of the torsion bar 1 to the spiral spring 5 takes place via a ring plate 6, which both with the torsion bar 1 and with the spring is welded. The screw 3 is also welded to the spiral spring 5. The threaded pin 17 serves to prevent the screw 3 from rotating.

In Fig. 2 ist eine Ansicht des Schraubendrehers von der Sechskantkugelkopfspitze her dargestellt. Aus ihr sind die Querschnitte der einzelnen Teile 4, 7 sowie die Lage und Weite der Ausnehmung 13 und die Form der Vorsprünge 12 ersichtlich. Der Drehstab 1 ist aus einem Stahl und der Griff 8 vorzugsweise aus Aluminium hergestellt.In Fig. 2 is a view of the screwdriver from the hex ball head tip shown here. From it the cross-sections of the individual parts 4, 7 and the The position and width of the recess 13 and the shape of the projections 12 can be seen. Of the The torsion bar 1 is made of a steel and the handle 8 is preferably made of aluminum.
