Abstract
Vis tête fraisée auto-fraiseuse destinée à l’assemblage des deux éléments d’un ensemble Le dispositif selon l’invention est constitué par l’ajout d’arêtes en saillie (12) ou autres dispositifs abrasifs sur la tête conique (11) d’une vis tête fraisée (10) La fraisure dans l’un des éléments est réalisée automatiquement sous l’effet de la rotation de la vis dans le sens horaire des aiguilles d’une montre conjugué à la force verticale dirigée de haut en bas engendrée par l’action de vissage Le dispositif de l’invention permet de s’affranchir de l’utilisation d’un outil appelé fraise de simplifier les opérations d’assemblage par vis à tête fraisée et d’améliorer le rendement La vis tête fraisée auto-fraiseuse objet de l’invention s’adresse aux industriels aux artisans mais également à tous les passionnés de bricolage Figure pour l’Abrégé [Fig 2)Self-milling countersunk head screw intended for the assembly of the two elements of an assembly The device according to the invention is constituted by the addition of projecting edges (12) or other abrasive devices on the conical head (11) of a countersunk head screw (10) The countersink in one of the elements is carried out automatically under the effect of the rotation of the screw in the clockwise direction of the needles of a clock combined with the vertical force directed from top to bottom generated by the screwing action The device of the invention makes it possible to dispense with the use of a tool called a milling cutter, to simplify assembly operations using countersunk screws and to improve performance. - milling machine object of the invention is intended for manufacturers and craftsmen but also for all DIY enthusiasts Figure for the Summary [Fig 2)
Description
La présente invention concerne une vis tête fraisée à tête auto-fraiseuse La vis auto-fraiseuse selon l’invention permet de supprimer l’opération de fraisage de l’empreinte conique de la tête de la dite vis dans un des deux éléments d’un ensemble sans devoir utiliser un outil spécifique appelé fraiseThe present invention relates to a countersunk head screw with a self-milling head. The self-milling screw according to the invention makes it possible to eliminate the milling operation of the conical recess of the head of said screw in one of the two elements of a together without having to use a specific tool called a milling cutter
Le procédé de réalisation du fraisage de l’empreinte d’une tête de vis est connu de l’état de la technique antérieure Il faut en premier procéder au perçage de l’un des deux éléments à l’aide d’un foret de taille légèrement supérieure au diamètre de la vis En second procéder au fraisage de l’empreinte de la tête de vis à l’aide d’un outil spécifique appelé fraise L’inconvénient réside dans le fait de devoir utiliser deux outils différents et par là même de procéder à deux opérations d’usinage successives La profondeur de l’empreinte est difficilement maîtrisable lors de l’utilisation d’une fraise avec une perceuse à main le résultat optimum ne pouvant être obtenu que sur une perceuse fixe équipée d’une butée de profondeur La conséquence du procédé ci-dessus est une réalisation approximative et chronophage Une autre technique consiste à employer des forets étagés effectuant simultanément les deux opérations décrites ci-dessus le perçage et le fraisage L’inconvénient réside dans le fait que le prix de ces forets est élevé et qu’il faut en outre posséder autant de diamètre de forets que de diamètre de vis et que chaque type de foret doit être adapté au diamètre de la vis à poserThe process for milling the recess of a screw head is known from the state of the prior art. It is first necessary to drill one of the two elements using a size drill bit. slightly larger than the diameter of the screw Second, proceed with milling the recess of the screw head using a specific tool called a milling cutter The disadvantage lies in the fact of having to use two different tools and thereby carry out two successive machining operations The depth of the recess is difficult to control when using a cutter with a hand drill the optimum result can only be obtained on a fixed drill equipped with a depth stop The consequence of the above process is an approximate and time-consuming realization Another technique consists in using stepped drills performing simultaneously the two operations described above drilling and milling The disadvantage lies in the fact that the price of these drills is high and that it is also necessary to have as many drill diameters as screw diameters and that each type of drill must be adapted to the diameter of the screw to be installed
La présente invention vise à palier ces inconvénients et propose de supprimer l’opération de fraisage à l’aide de l’outil spécifique appelé fraise Le fraisage de l’un des éléments à assembler est réalisé automatiquement par l’action d’abrasion des dispositifs intégrés à la tête de la vis auto-fraiseuse L’usinage de la fraisure est réalisé automatiquement sous l’effet de rotation de la vis auto-fraiseuse dans le sens horaire conjugué avec la force verticale dirigée de haut en bas engendrée par l’action de vissageThe present invention aims to overcome these drawbacks and proposes to eliminate the milling operation using the specific tool called milling cutter. The milling of one of the elements to be assembled is carried out automatically by the action of abrasion of the devices integrated into the head of the self-milling screw The machining of the countersink is carried out automatically under the effect of rotation of the self-milling screw in the clockwise direction combined with the vertical force directed from top to bottom generated by the action screwing
