Description

Vorrichtung zum Überziehen von Schrauben mit einer zu ihrer Sicherung dienenden hochviscosen Silikonmasse Ein neues Schraubensicherungsverfahren macht von bestimmten Eigenschaften gewisser Silikone Gebrauch. Hierbei werden hochviskose, sich nicht vernetzende, plastische und stoßelastische Methylpolysiloxane so verwendet, daß eine kleine Menge der weichen, pastenartigen Silikonmasse, zwischen Schrauben- und Mutterngewinde gebracht, sich beim Eindrehen der Gewindeteile verteilt und sie derart haftend zusammenhält, daß ein selbständiges Lockern oder Verdrehen nicht möglich ist. Das Haften tritt sofort ein und verstärkt sich erheblich nach einer gewissen Standzeit. Wirkt dagegen auf die Gewindeverbindung eine stetige Verdrehungsbeanspruchung ein, dann löst sich die Verschraubung ohne merkbaren Widerstand, so daß die beiden Teile nach Belieben auch feinfühlig gegeneinander verstellt sowie auseinandergeschraubt und wieder zusammengefügt werden können.Device for covering screws with a device to secure them used high-viscosity silicone mass A new screw locking process makes use of certain properties of certain silicones. Here, highly viscous, non-crosslinking, plastic and shock-elastic methylpolysiloxanes are used in such a way that that a small amount of the soft, paste-like silicone mass, between screw and nut threads, distributed when screwing in the threaded parts and they so adheres together that an independent loosening or twisting does not is possible. The sticking occurs immediately and increases considerably after one certain service life. If, on the other hand, a constant torsional stress acts on the thread connection one, then the screw connection loosens without noticeable resistance, so that the two Parts can also be sensitively adjusted against each other and screwed apart at will and can be put back together again.

In der Praxis besteht die Schwierigkeit, die Silikonmasse in die Schraubverbindung zu bringen, d. h. die Schrauben in geeigneter Weise mit der Silikonmasse zu überziehen.In practice there is the difficulty of getting the silicone compound into the screw connection to bring, d. H. to cover the screws in a suitable manner with the silicone compound.

Die Erfindung löst diese Aufgabe mittels einer Vorrichtung, die durch einen an sich von Spritzgußmaschinen her bekannten rohrförmigen Teil mit zum Vordrucken der Masse dienender Schnecke und einem anschließenden Beschichtungsraum, der durch eine Lochplatte oder ein Gitter zum Einstecken der Schrauben abgeschlossen wird, gekennzeichnet ist.The invention solves this problem by means of a device that by a tubular part known per se from injection molding machines for preprinting the screw serving the mass and an adjoining coating room that runs through a perforated plate or a grid for inserting the screws is completed, is marked.

Die Schrauben werden dabei von außen bis zum Kopfteil durch die gerade passenden Löcher der Lochplatte oder des Gitters gesteckt, so daß sie mit ihrem Gewindeteil in den Beschichtungsraum hineinragen. Die ,sich drehende Schnecke fördert die Silikonmasse in den Beschichtungsraum, und die Schrauben werden augenblicklich bis zum Gewindegrund überzogen. Beim Herausziehen der Schrauben oder bei ihrem Herausdrücken wird die überschüssige Masse an den Lochrändern abgestreift.The screws are straight from the outside to the head part matching holes of the perforated plate or the grid inserted so that they can with your Thread part protrude into the coating room. The rotating screw conveys the silicone mass into the coating room, and the screws are instantaneous Coated to the bottom of the thread. When pulling out the screws or when pushing them out the excess mass is stripped off at the edges of the hole.

Zum Herausdrücken der Schrauben kann die Vorrichtung weiterhin beispielsweise so ausgebildet werden, daß die Schneckenwelle im Beschichtungsraum in eine Gewindestange ausläuft, die eine in Rillen an der Innenwand geführte, mit vielen kleinen Löchern und mit dem Gewinde der Gewindestange versehene Scheibe trägt, die sich durch die Drehung der Schneckenwelle in Richtung zur Lochplatte bewegt und die beschichteten Schrauben herausdrückt.In order to push out the screws, the device can also, for example be designed so that the worm shaft in the coating room in a threaded rod runs out, the one guided in grooves on the inner wall, with many small holes and carries with the thread of the threaded rod provided, which extends through the Rotation of the worm shaft moves towards the perforated plate and the coated Screws out.
