Abstract

The grip is used to hold tools, with cylindrical shafts, which have four tangential grooves (23,24,25,26) which are equi-spaced around the circumference of the tool shaft. The grip has two fixed edges (28,29) which engage with two of the grooves in the tool and two edges (27,30) which are located on pivoting levers (5,7). The pivoting levers consist of short upper arms (6,8), which are loaded apart by a spring (14), and longer lower arms. Rollers (19,20) are mounted on the ends of the longer arms. the rollers make it easier to push the grip over the cylindrical tool shaft

Description

Die Erfindung betrifft einen Werkzeuggreifer für Werkzeuge mit vier gleichmäßig über einen zylindrischen Haltebund ver­ teilten Tangentialnuten, denen zwei ortsfeste und zwei hin- und herbewegbare, an den längeren Armen zweier Schwenkhebel angeordnete Halteleisten zugeordnet sind.The invention relates to a tool gripper for tools ver with four evenly over a cylindrical retaining collar shared tangential grooves, two fixed and two facing and movable, on the longer arms of two swivel levers arranged holding strips are assigned.

Bekannt sind Werkzeuggreifer der vorstehenden Art, bei denen der Greifvorgang durch Sensoren pneumatisch gesteuert wird. Der Aufwand für die Herstellung derartiger Greifer und die Kosten für ihre steuerungstechnische Einbindung in Werkzeug­ handhabungssysteme sind nicht unbeträchtlich. Hinzu kommt ein verhältnismäßig hoher Raumbedarf, da die Unterbringung der Pneumatik im Greifer vergleichsweise viel Platz beansprucht.Tool grippers of the above type are known, in which the gripping process is pneumatically controlled by sensors. The effort for the production of such grippers and the Costs for their control engineering integration in tools handling systems are not inconsiderable. In addition there is one relatively high space requirements, since the accommodation of the Pneumatics in the gripper take up a comparatively large amount of space.

Der Erfindung liegt die Aufgabe zugrunde, einen Greifer der in Betracht gezogenen Art zu schaffen, der einfach und kom­ pakt aufgebaut und ohne Energiezufuhr von außen einsetzbar ist. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen den kürzeren Armen der Schwenkhebel mindestens ein, die längeren Arme in ihre Halteposition drückendes Federele­ ment angeordnet ist.The invention has for its object a gripper contemplated kind of creating that simple and com built compact and can be used without external energy supply is. This object is achieved in that at least one between the shorter arms of the swivel levers,  Federele pushing the longer arms into their holding position ment is arranged.

Der erfindungsgemäße Werkzeuggreifer besteht aus wenigen Tei­ len und ist praktisch wartungsfrei.The tool gripper according to the invention consists of a few parts len and is practically maintenance-free.

Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachstehenden Beschreibung einer in der beigefügten Zeichnung dargestellten, besonders vorteilhaften Ausführungsform. Es zeigen:Further details and features of the invention emerge from the subclaims and the description below one shown in the accompanying drawing, particularly advantageous embodiment. Show it:

In den Figuren sind 1 und 2 zwei auf Achsen 3 und 4 gelagerte Schwenkhebel mit jeweils ungleich langen Armen 5, 6 bzw. 7, 8. Die Schwenkhebel 1, 2 sind in einer Aussparung 9 des Unter­ teils 10 eines Gehäuses gelagert, zu dem ein Deckel 11 ge­ hört. Zwischen den mit Stützflächen 12, 13 versehenen Enden der kürzeren Arme 6, 8 der Schwenkhebel 1, 2 ist mindestens eine Druckfeder 14 angeordnet, die sich mit ihren Enden über Kugeln 15, 16 an den Stützflächen 12, 13 abstützt. Die Druckfe­ der 14 hält die Schwenkarme 1, 2 in der in Fig. 1 dargestell­ ten Lage, in der die kürzeren Arme 6, 8 gegen die Seitenwände 17, 18 des Unterteils 10 des Gehäuses anliegen. An den äußeren Enden der längeren Arme 5, 7 der Schwenkhebel 1, 2 sind Rollen 19, 20 angeordnet, die das Ein- und Ausfahren eines Werkzeugs 21 erleichtern. Wie aus Fig. 2 erkennbar, ist das Werkzeug mit vier gleichmäßig über einen Haltebund 22 verteilten Haltenuten 23 bis 26 versehen, in die Halteleisten 27 bis 30 einrasten können, von denen zwei am Unterteil 10 des Gehäuses und zwei an den längeren Armen 5, 7 der Schwenkhebel 1, 2 an­ geordnet sind.In the figures 1 and 2 are two pivot levers mounted on axes 3 and 4 , each with arms 5 , 6 and 7 , 8 of unequal length. The pivot levers 1 , 2 are mounted in a recess 9 of the lower part 10 of a housing, to which a cover 11 listens. At least one compression spring 14 is arranged between the ends of the shorter arms 6 , 8 of the swivel levers 1 , 2 provided with support surfaces 12 , 13 and their ends are supported on the support surfaces 12 , 13 by means of balls 15 , 16 . The Druckfe of 14 holds the swivel arms 1 , 2 in the position shown in FIG. 1, in which the shorter arms 6 , 8 rest against the side walls 17 , 18 of the lower part 10 of the housing. At the outer ends of the longer arms 5 , 7 of the swivel levers 1 , 2 , rollers 19 , 20 are arranged which facilitate the insertion and removal of a tool 21 . As can be seen from FIG. 2, the tool is provided with four holding grooves 23 to 26 , evenly distributed over a holding collar 22 , into which holding strips 27 to 30 can snap, two of which are on the lower part 10 of the housing and two on the longer arms 5 , 7 the pivot lever 1 , 2 are arranged on.
