Description

Es hat sich nach langen Versuchen herausgestellt, daß bei HoeMrequenz-Aufnahmeapparaten der Greifer das am meisten beanspruchte Glied ist, und daß dieses Organ einer ganz besonders gewissenhaften Ausführung bedarf. Bei den gewöhnlichen Greifern hat sich gezeigt, daß sie infolge der außerordentlichen Geschwindigkeit, mit welcher sie bewegt werden, einfach verbogen und, vernichtet wurden. Man ist deshalb dazu übergegangen, dem Träger der Greifersitifte einen Querschnitt von größerer Knickfestigkeit zu geben, z. B. durch verstärkende Rippen an den Rändern.It has been found, after long tests, that in the case of HoeMrefrequenz recording apparatus the claw is the most stressed member, and that this organ is particularly conscientious in execution requirement. In the case of the ordinary claws it has been shown that, as a result of the extraordinary The speed at which they are moved, simply bent and destroyed became. One has therefore gone over to the carrier of the gripper pins To give cross-section of greater buckling strength, z. B. by reinforcing ribs on the Margins.

In den Abbildungen ist der den Gegenstand der Erfindung bildende Greifer veranschaulicht, und zwar stellt Abb. 1 die Ansicht von vorn dar, Abb. 2 einen Schnitt und Abb. 3 den Grundriß.In the figures, the gripper forming the subject of the invention is illustrated, namely, Fig. 1 shows the view of at the front, Fig. 2 is a section and Fig. 3 is the plan.

Der Greifer aus einem gehärteten Stahlblech α vom geeigneter Form ist erfindiungsgemäß auf seine ganze Länge von den Greiferspitzen bis zum Schwanz durch an sich bekannte, hoch-gezogene Streben b versteift, wo-According to the invention, the gripper made of hardened sheet steel α of a suitable shape is stiffened over its entire length from the gripper tips to the tail by means of well-known, high-drawn struts b , where-

as durch ein Verbiegen des Greiferbledies vereitelt wird, und gleichzeitig sind die beiden Streben δ durch das ebenfalls gehärtete Lagerrohr c verbunden und dienen in einfachster Weise als dessen Träger. Der Greiferschwanz d ist umgerollt und bei / festgenietet, und die dabei entstandene Öffnung / dient ebenfalls als Lager. Mithin ist auf einfachste Weise ein Greifer geschaffen, der hohen Anforderungen genügt.As is thwarted by bending the gripper slice, and at the same time the two struts δ are connected by the also hardened bearing tube c and serve in the simplest way as its carrier. The gripper tail d is rolled over and riveted to /, and the resulting opening / also serves as a bearing. A gripper that meets high requirements is therefore created in the simplest possible way.

An geeigneten Stellen kann das Blech des Greifers ausgespart werden, um sein Eigengewicht zu verringern, ohne daß er an Stabilität verliert.The sheet metal of the gripper can be cut out at suitable points to reduce its own weight without losing stability.
