Description
L'invention concerne un dispositif de montage d'agrafes de fixation et plus particulièrement un dispositif de montage d'agrafes qui comportent deux bras qui agissent radialement sur un axe fixe afin de maintenir en position des écrans thermiques ou tout autre type d'élément.The invention relates to a fixing clip mounting device and more particularly to a staple mounting device which comprises two arms which act radially on a fixed axis in order to keep thermal screens or any other type of element in position.
En général, sur les chaînes de montage, les agrafes du type qui comportent deux bras qui agissent radialement sur un axe fixe sont mises en place manuellement. Le montage est effectué par l'opérateur en exerçant une pression sur les bras de l'agrafe afin de permettre le coulissement de ladite agrafe sur l'axe de fixation. Or une certaine pression est recommandée pour la mise en place des agrafes. La mise en pression est donc plus difficile et moins précise manuellement, ce qui peut provoquer une disparité dans la qualité du montage. De plus, la mise en place manuelle d'agrafes de façon répétitive peut occasionner des gênes et des désagréments physiques pour l'opérateur, en particulier au niveau des doigts. Les désagréments physiques engendrés produisent des disparités dans la qualité de fixation de l'agrafe.In general, on the assembly lines, the staples of the type which comprise two arms which act radially on a fixed axis are put in place manually. The assembly is performed by the operator by exerting pressure on the arms of the clip to allow the sliding of said clip on the fixing axis. But some pressure is recommended for the implementation of staples. Pressurizing is therefore more difficult and less precise manually, which can cause a disparity in the quality of assembly. In addition, the manual placement of staples repeatedly can cause inconvenience and physical discomfort for the operator, especially at the fingertips. The physical inconvenience caused produces disparities in the quality of fixation of the clip.

Le document
Afin de pallier ces inconvénients, l'invention a pour objet un dispositif léger, maniable et précis permettant de mettre en place une agrafe de façon automatique et dans les endroits difficiles d'accès tout en assurant une homogénéité dans la qualité de fixation.In order to overcome these drawbacks, the object of the invention is a light, manageable and precise device which makes it possible to set up a staple automatically and in places that are difficult to access while ensuring homogeneity in the quality of fixation.
Selon une caractéristique de l'invention, le poussoir comporte au moins deux zones de pression distinctes qui coopèrent respectivement avec les bras de l'agrafe.According to one characteristic of the invention, the pusher comprises at least two distinct pressure zones which cooperate respectively with the arms of the staple.
Selon une autre caractéristique de l'invention, le poussoir est monté en translation dans un guide en limitant les mouvements de rotation relatifs entre lesdits guide et poussoir.According to another characteristic of the invention, the pusher is mounted in translation in a guide by limiting the relative rotational movements between said guide and pusher.
Selon une autre caractéristique de l'invention, le poussoir comporte un orifice central d'un diamètre supérieur au diamètre de l'axe de montage.According to another characteristic of the invention, the pusher comprises a central orifice with a diameter greater than the diameter of the mounting axis.
Selon une autre caractéristique de l'invention, la jonction des bras avec la base de l'agrafe sont montées à translation dans des rainures réalisées selon la direction x dans le guide.According to another characteristic of the invention, the junction of the arms with the base of the clip are mounted in translation in grooves made in the x direction in the guide.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'exemples de réalisation d'un dispositif d'aide au montage d'une agrafe de fixation au dessin annexé dans lequel :

La présente invention portant essentiellement sur l'embout d'un outil d'aide au montage d'agrafes, la description qui suit ne décrit pas la partie standard et connue en soi de l'outil qui comporte les éléments de transmission d'effort par l'intermédiaire de moyens pneumatiques ou d'autres moyens équivalents.The present invention essentially relates to the tip of a staple assist tool, the following description does not describe the standard part and known per se of the tool which comprises the force transmission elements via pneumatic means or other equivalent means.
Tel que représenté sur la
L'agrafe 4, telle que décrite sur les
Le poussoir 7 est monté en translation suivant l'axe x dans un guide fixe 2 qui forme l'embout de l'outil. L'agrafe 4 est positionnée de façon à ce que les bras 8 et 9 de cette dernière soient en contact avec une partie externe du poussoir 7. Tel que représenté sur la
Le guide 2 et le poussoir 7 sont de section rectangulaire afin que les zones de pression aient toujours la même orientation par rapport au corps de l'outil.The
Avantageusement, des rainures 15 et 16 peuvent aussi être ajoutées sur le guide 2 afin de limiter la rotation de l'agrafe 4 dans l'embout et peuvent également servir de maintien de l'agrafe afin que cette dernière ne tombe pas au cours de l'opération.Advantageously,
Afin de positionner l'agrafe 4 sur l'axe 5, l'opérateur place l'agrafe 4 dans l'embout de l'outil en faisant coopérer les extrémités libres 13 et 14 des bras 8 et 9 respectivement avec les zones d'appui 11 et 12, tel que représenté sur la
