Abstract
Description
La présente invention concerne les inserts métalliques destinés à être mis en place dans des pièces en thermoplastiques,pour donner par exemple des filetages,des taraudages,des axes;elle crée,notamment un insert qui est conçu pour etre mis en place à laide d'un dispositif à ultrasons. The present invention relates to metal inserts intended to be put in place in thermoplastic parts, to give for example threads, threads, pins; it creates, in particular an insert which is designed to be put in place using an ultrasonic device.
L'insert conforme à l'invention comprend un corps ayant une partie principale à une extremité,un groupe de dents hélicoidales,un groupe de dents circulaires et au moins une rainure périphérique. The insert according to the invention comprises a body having a main part at one end, a group of helical teeth, a group of circular teeth and at least one peripheral groove.
De préférence,les dents hélicoidales sont inclinées dans le sens du vissage par rapport à l'axe,les dents circulaires sont perpendiculaires à l'axe et les deux groupes sont espacés par une rainure périphérique.Le groupe à l'extremité opposée à la partie principale est,de préférence,d'un diamètre légerement plus grand. Preferably, the helical teeth are inclined in the direction of screwing relative to the axis, the circular teeth are perpendicular to the axis and the two groups are spaced by a peripheral groove. The group at the end opposite to the part main is preferably of a slightly larger diameter.
L'invention est représentée,à titre d'exemple non limitatif,au dessin annexé. The invention is shown, by way of nonlimiting example, in the accompanying drawing.
La fig. 1 est une vue en élévation d'un insert. Fig. 1 is an elevational view of an insert.
La fig. 2 est une coupe transversale médiane longitudinale de l'insert de la fig. 1
Au dessin annexé,l'insert comprend un corps généralement cylindrique désigné par(l0) ayant un alésage axial fileté (12).Deux groupes de dents, en hélice (13),circulaire (14),sont formés autour de la surface extérieure de l'insert,les deux groupes étant séparés par une rainure radiale périphérique (15).Un rebord principal ou bout pilote (19) fait suite au groupe de dents circulaires (14).Fig. 2 is a longitudinal median cross section of the insert of FIG. 1
In the accompanying drawing, the insert comprises a generally cylindrical body designated by (10) having a threaded axial bore (12). Two groups of teeth, helical (13), circular (14), are formed around the outer surface of the insert, the two groups being separated by a peripheral radial groove (15). A main rim or pilot end (19) follows the group of circular teeth (14).
Le diamètre sur flanc de dent (R) du groupe (14) est égal au diamètre du rebord principal (19). The diameter on the tooth flank (R) of the group (14) is equal to the diameter of the main rim (19).
Le diamètre sur flanc de dent (S) du groupe (13) est égal au diamètre en sommet de dent du groupe (14). The diameter on the tooth flank (S) of the group (13) is equal to the diameter at the top of the group's tooth (14).
Lors de la mise en place,l'insert est disposé dans un trou principal en matière thermoplastique et le rebord principal ou bout pilote (19) et la base de la première dent (17) du groupe (14) s'engagent dans ce trou tandis que le flanc de la première dent (17) bute contre le rebord du trou etsert à maintenir l'insert avec son axe perpendiculaire à la surface de la matière.L'insert est ensuite amené à vibrer par voie ultrasonore,ce qui provoque l'échauffement et l'écoulement de la matière plastique autour de I'insert qui se met en place dans son trou. During installation, the insert is placed in a main hole in thermoplastic material and the main rim or pilot tip (19) and the base of the first tooth (17) of the group (14) engage in this hole while the flank of the first tooth (17) abuts against the edge of the hole and serves to maintain the insert with its axis perpendicular to the surface of the material. The insert is then caused to vibrate ultrasonically, which causes the 'heating and flow of the plastic around the insert which is placed in its hole.
L'utilisation de dents horizontales et hélicoidales assure un maintien axial et de contre-rotation.La matière plastique s'écoule dans les dents horitales (14) et la rainure (15) et lorsqu'elles sont remplies le maintien axial principal est obtenu.La partie de plus grand diamètre (13) assure que les dents sont encastrées dans la matière plastique d'une manière satisfaisante, les dents (13) pénetrant seulement dans la matière plastique après que le groupe inférieur (14) a été déplacé de cette matière.La rotation qui se produit lors de l'encastrement des dents hélicoldales (13) assure un remplissage homogène de toutes les dents et rainure.Les dents hélicoidales assure principalement la contre-rotation mais participe aussi au maintien axial. The use of horizontal and helical teeth ensures axial and counter-rotating support. The plastic material flows into the horizontal teeth (14) and the groove (15) and when they are filled the main axial support is obtained. The larger diameter portion (13) ensures that the teeth are satisfactorily embedded in the plastic, the teeth (13) penetrating only into the plastic after the lower group (14) has been moved from this material .The rotation which occurs during the embedding of the helical teeth (13) ensures a homogeneous filling of all the teeth and groove.The helical teeth mainly ensures the counter-rotation but also participates in the axial maintenance.
A titre de variante,les dents du groupe (13)peuvent être parallèle à l'axe. Alternatively, the teeth of the group (13) can be parallel to the axis.
Une autre variante,les dents du groupe (14) peuvent être hélicoidales et de sens opposé au groupe de dents (13). Another variant, the teeth of the group (14) can be helical and in the opposite direction to the group of teeth (13).
