Abstract

The subject of the present invention is a screwing socket including means for holding and retaining a nut and means for transmitting the rotational movement of the rotating spindle (4) of an automatic screwing machine to the nut. According to the invention it comprises a driver (1) equipped with means for fastening to the spindle (4), an adaptor piece (2) which is connected to the driver (1) by means for driving with play, and includes means for driving the nut and a magnet (7) for retaining the nut in the adaptor piece (2).

Description

La présente invention concerne une douille de vissage d'écrous. Les douilles de vissage jusqu'à présent réalisées ne sont pas utilisables de manière fiable sur une machine automatique. En effet, la douille doit permettre d'assurer le vissage d'un écrou sur une vis ou un goujon dont la position n'est pas rigoureuse à l'aide d'une visseuse dont la position est au contraire très précise.The present invention relates to a nut screwing socket. The screw sockets so far produced cannot be used reliably on an automatic machine. Indeed, the socket must allow the screwing of a nut on a screw or a stud whose position is not rigorous using a screwdriver whose position is on the contrary very precise.

La douille de vissage qui résoud ce problème comporte des moyens pour prendre et retenir un écrou et des moyens pour transmettre à l'écrou le mouvement de rotation de la broche tournante d'une visseuse automatique et est caractérisée en ce qu'elle comprend un entraîneur muni de moyens de fixation à la broche, et un embout qui est relié à l'entraîneur par des moyens d'entraînement avec jeu et comporte des moyens d'entraînement de l'embout et un aimant pour retenir l'écrou dans l'embout. The screwing sleeve which solves this problem comprises means for taking and retaining a nut and means for transmitting to the nut the rotational movement of the rotary spindle of an automatic screwdriver and is characterized in that it comprises a driver provided with means for fixing to the spindle, and an end piece which is connected to the driver by drive means with play and comprises means for driving the end piece and a magnet for retaining the nut in the end piece .

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation d'une douille selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 est une vue en coupe
axiale de la douille;
Les Figures 2 à 4 en sont des vues
en coupe transversale respectivement
selon II-II,III-III et IV-IV de
la Figure 1.An embodiment of a socket according to the invention has been described below, by way of nonlimiting example, with reference to the appended drawing in which
Figure 1 is a sectional view
axial of the socket;
Figures 2 to 4 are views
in cross section respectively
according to II-II, III-III and IV-IV of
Figure 1.

Telle qu'elle est représentée au dessin, la douille comprend un entraîneur 1 et un embout 2.As shown in the drawing, the socket comprises a driver 1 and a nozzle 2.

L'une des extrémités de l'entraîneur 1 est filetée extérieurement; elle est munie de fentes longitudinales de manière à former une pince et d'un perçage la de section carrée. Elle peut ainsi être fixée par un écrou conique 3 sur le carré d'entraînement de la broche 4 d'une visseuse. Dans sa partie centrale, l'entraîneur présente une section extérieure carrée qui est emmanchée avec jeu dans une partie femelle carrée 2a de l'embout 2. La partie de l'entraîneur opposée à la pince, qui présente un perçage axial lb, a une section extérieure circulaire et est emmanchée avec jeu dans une partie cylindrique 2b d'embout 2; la liaison entre les deux éléments est assurée par une goupille de retenue 5 et des tampons élastiques 6.One end of the driver 1 is externally threaded; it is provided with longitudinal slots so as to form a clamp and a hole 1a of square section. It can thus be fixed by a conical nut 3 on the drive square of spindle 4 of a screwdriver. In its central part, the coach has a square outer section which is fitted with play in a square female part 2a of the end piece 2. The part of the coach opposite the clamp, which has an axial bore lb, has a circular outer section and is fitted with clearance in a cylindrical part 2b of end piece 2; the connection between the two elements is ensured by a retaining pin 5 and elastic buffers 6.

L'extrémité de l'embout 2 opposée à sa partie femelle 2a présente un évidement en six pans 2c qui se raccorde à la partie cylindrique 2b par un épaulement 2d. Un aimant de retenue cylindrique 7, aimanté dans le sens de ses génératrices, est logé dans un isolateur cylindrique 8 qui est interposé entre l'extrémité cylindrique de l'entraîneur 1 et l'épaulement 2d de l'embout. Le fond de l'isolateur 8 est percé d'un trou 8a dont le diamètre est égal au diamètre intérieur de l'aimant 7.The end of the end piece 2 opposite its female part 2a has a hexagonal recess 2c which is connected to the cylindrical part 2b by a shoulder 2d. A cylindrical retaining magnet 7, magnetized in the direction of its generatrices, is housed in a cylindrical insulator 8 which is interposed between the cylindrical end of the driver 1 and the shoulder 2d of the end piece. The bottom of the insulator 8 is pierced with a hole 8a, the diameter of which is equal to the inside diameter of the magnet 7.

L'écrou à visser 9 est prélevé dans un distributeur automatique et placé dans l'évidement 2c de l'embout dans lequel il est retenu par l'aimant 7. Le jeu entre l'embout et l'entraîneur permet de mettre en place l'écrou 9 sur un goujon 10 dont la position peut varier d'environ un millimètre alors que la visseuse 4 se trouve à une position précise. Lors du vissage, le goujon 10 pénètre dans le perçage axial lb de l'entraîneur 1.The screw nut 9 is taken from an automatic distributor and placed in the recess 2c of the end piece in which it is retained by the magnet 7. The play between the end piece and the driver makes it possible to set up the 'nut 9 on a stud 10 whose position can vary by about a millimeter while the screwdriver 4 is in a precise position. During screwing, the stud 10 enters the axial bore 1b of the driver 1.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes.  It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
