  PORTE OUTIL A LAME REGLABLE

  
L'invention est relative aux porte-outils à lame réglable du type dans lequel une lame est montée dans un support tournant conjointement avec des organes en forme de coin combinés à un dispositif de serrage, le blocage étant assuré par ce dispositif et l'action de la force centrifuge.

  
Dans un agencement déjà proposé, la lame était engagée avec les coins dans une rainure de profil trapézoïdal, ce qui comporte, entre autres inconvénients, ceux du démontage des paliers du support tournant pour permettre le dégagement des coins et un usinage difficile et dispendieux de la rainure du support.

  
L'invention a pour but surtout de supprimer ces inconvénients et de procurer en outre un porte outil dans lequel la force centrifuge agit d'une manière plus efficace pour assurer *le blocage.

En outre, en raison de la conformation qui est donnée à l'organe agissant à la manière d'un coin, le centre des pressions dues à l'action de la force centrifuge est reporté à une distance plus importante du centre- de rotation, en sorte que, toutes choses égales, l'effet de blocage sur la lame est ainsi renforcé.

  
Et afin que l'on puisse bien comprendre de quelle manière l'objet de l'invention pourra être pratiquement réalisé, on le

La lame 2 est, comme il est représenté, sollicitée

  
par un ressort 3 disposé dans un logement 4 de façon à faciliter au besoin le dégagement de la lame, et d'autre part l'organe 5 est équipé d'un dispositif de serrage représenté par une vis 7 agissant sur le fond de la rainure 9 par l'intermédiaire d'une bille 8.

 <EMI ID=13.1> 

  
Conformément à la figure 2, cette action de blocage est encore renforcée en écartant le dispositif du vis de serrage 7 de la face d'appui 6.

  
La figure 3 montre que les rainures 9 pourront être conformées aisément en deux opérations, savoir, une pénétration suivant la direction A et une pénétration suivant la direction B, tandis,que dans les dispositifs comportant des rainures de forme trapézoïdale trois opérations de pénétration au moins étaient indispensables pour exécuter les rainures.

  
Comme il va de soi, et comme on l'a déjà laissé enten- . dre, il est bien entendu que les formes d'exécution décrites ne sont que des exemples et que l'on pourrait s'en écarter sans se départir de l'esprit de l'invention.

  ADJUSTABLE BLADE TOOL HOLDER

  
The invention relates to tool holders with an adjustable blade of the type in which a blade is mounted in a rotating support together with wedge-shaped members combined with a clamping device, the locking being provided by this device and the action centrifugal force.

  
In an arrangement already proposed, the blade was engaged with the corners in a trapezoidal profile groove, which has, among other drawbacks, those of removing the bearings from the rotating support to allow clearance of the corners and difficult and expensive machining of the blade. support groove.

  
The object of the invention is above all to eliminate these drawbacks and furthermore to provide a tool holder in which the centrifugal force acts in a more efficient manner to ensure * the locking.

  
 <EMI ID = 1.1>

  
 <EMI ID = 2.1> ..- of a corner and suitable for being engaged and disengaged radially from the groove of the support member this groove-having a profile such that its machining can be easily ensured at little de'ferais.

  
In addition, due to the conformation which is given to the member acting in the manner of a wedge, the center of the pressures due to the action of the centrifugal force is transferred to a greater distance from the center of rotation, so that, other things being equal, the blocking effect on the blade is thus enhanced.

  
And so that we can fully understand how the object of the invention can be practically achieved, we

dials ent.

  
The blade 2 is, as it is represented, stressed

  
by a spring 3 arranged in a housing 4 so as to facilitate, if necessary, the release of the blade, and on the other hand the member 5 is equipped with a clamping device represented by a screw 7 acting on the bottom of the groove 9 via a ball 8.

  
 <EMI ID = 11.1>

  
 <EMI ID = 12.1>

  
so that all other things being equal the locking action on the blade

  
 <EMI ID = 13.1>

  
In accordance with FIG. 2, this locking action is further reinforced by moving the clamping screw device 7 away from the bearing face 6.

  
Figure 3 shows that the grooves 9 can be easily shaped in two operations, namely, a penetration in the direction A and a penetration in the direction B, while, in the devices comprising grooves of trapezoidal shape at least three penetration operations were essential to perform the grooves.

  
As goes without saying, and as we have already seen. dre, it is understood that the embodiments described are only examples and that one could depart from them without departing from the spirit of the invention.
