Abstract
Description
L'invention a pour objet un dispositif pour la mesure de l'angle de serrage sur une clé avec rallonge par rapport à un organe orienté dans une direction fixe. The invention relates to a device for measuring the tightening angle on a key with extension relative to a member oriented in a fixed direction.
Selon le procédé connu de serrage avec contrôle de l'angle de rota tion pour des éléments à vis, on mesure l'angle de rotation de la vis à partir d'une certaine position de départ qui peut être facilement déterminée dans tous les cas comparables et qui est donnée, par exemple, par la fin de rotation libre de la vis, se manifestant par une brusque croissance du couple nécessaire pour faire tourner cette vis. According to the known method of tightening with control of the angle of rotation for screw elements, the angle of rotation of the screw is measured from a certain starting position which can be easily determined in all comparable cases and which is given, for example, by the end of free rotation of the screw, manifested by an abrupt increase in the torque necessary to rotate this screw.
Les dispositifs connus pour le serrage d'assemblage à vis avec contrôle de l'angle de rotation ne sont guère maniables, car ils mesurent l'angle de rotation entre la clé à vis et la structure fixe à l'aide, d'une part, d'un organe qui est monté en rotation sur la clé à vis et, d'autre part, d'un index indépendant devant être raccordé avec une orientation à la structure fixe.Known devices for tightening a screw assembly with control of the angle of rotation are not very easy to handle, because they measure the angle of rotation between the screw key and the fixed structure using, on the one hand , a member which is rotatably mounted on the screw wrench and, on the other hand, an independent index to be connected with an orientation to the fixed structure.
L'invention a pour but de simplifier la construction et la manipulation d'un outil de ce genre, elle concerne donc un dispositif pour la mesure de l'angle de serrage sur Une. clé à vis, grâce ê un organe.qui est orienté d2ns une direction fixe et qui est monté libre en rotation sur cette.clé.pour indi- quer la direction de référence par rapport à un index solidaire de la clé.The invention aims to simplify the construction and handling of a tool of this kind, it therefore relates to a device for measuring the clamping angle on A. screw wrench, thanks to an organ which is oriented in a fixed direction and which is mounted to rotate freely on this key to indicate the reference direction with respect to an index secured to the key.
La solution proposée par l'invention consiste donc en ce que l'organe orienté dans une position fixe fait partie intégrante de l'outil et prend sa position fixe de référence par une immobilisation rapide (aimant) sur la structure fixe.The solution proposed by the invention therefore consists in that the member oriented in a fixed position forms an integral part of the tool and takes its fixed reference position by rapid immobilization (magnet) on the fixed structure.
La détermination de l'angle de rotation est effectuée opportunément au moyen d'une échelle graduée en unités d'angle et d'un repère de lecture qui coopèrent sur le corps.The determination of the angle of rotation is carried out expediently by means of a scale graduated in angle units and a reading mark which cooperate on the body.
Par terme "clé à vis", il y a lieu d'entendre dans le cadre de l'invention tous les outils destinés à faire tourner des assemblages à vis, quelque soit leur forme et mode d'entraînement.By the term "screw wrench", it is necessary to understand within the framework of the invention all the tools intended to rotate screw assemblies, whatever their form and drive mode.
En outre, un système de signalisation peut être raccordé au système de lecture. Ce terne doit être interprété dans le sens le plus large. I1 recouvre non seulement des systèmes qui émettent un signal acoustique, optique ou autre lorsque l'angle prescrit est atteint.In addition, a signaling system can be connected to the reading system. This dull must be interpreted in the widest sense. It not only covers systems which emit an acoustic, optical or other signal when the prescribed angle is reached.
Selon une première caractéristique,l'invention vise un dispositif du type comportant un disque gradué (8) solidaire de l'un des éléments (tube 9) et un index (3) solidaire des autres éléments (2, 5).According to a first characteristic, the invention relates to a device of the type comprising a graduated disc (8) integral with one of the elements (tube 9) and an index (3) integral with the other elements (2, 5).
Caractérisé en ce qu'il comporte - une butée destinée à être fixée sur la rallonge (5) de la clé - un tube destiné à venir prendre appui sur ladite butée (6), qui est monté
libre en rotation sur la rallonge (5) coaxialement à celle-ci, et qui est
pourvu d'une part en partie supérieure d'un disque gradué (8) maintenu
solidaire de celui-ci et d'autre part de moyens de liaison (10, 11, 12) à
la structure fixe. Characterized in that it comprises - a stop intended to be fixed on the extension (5) of the key - a tube intended to come to bear on said stop (6), which is mounted
free to rotate on the extension (5) coaxial therewith, and which is
provided on the one hand in the upper part with a graduated disc (8) maintained
integral with it and on the other hand with connecting means (10, 11, 12) to
the fixed structure.
- un anneau (2) pourvu de moyens de solidarisation à la rallonge (5) sur
lequel est fixé l'index (3).- a ring (2) provided with means for securing to the extension (5) on
which is fixed the index (3).
L'invention est expliquée ci-après de façon plus détaillée en référence aux dessins annexés, illustrée par une vue en perspective éclatée de l'outil (figure 1) et une vue de l'outil assemblé (figure 2). L'outil représenté est un outil que l'on doit faire tourner à la main à l'aide d'un levier ou clé, accouplable au moyen d'un quatre pans à l'évidement (4) de la rallonge (5).The invention is explained below in more detail with reference to the accompanying drawings, illustrated by an exploded perspective view of the tool (Figure 1) and a view of the assembled tool (Figure 2). The tool shown is a tool that must be rotated by hand using a lever or wrench, which can be coupled by means of a hexagon to the recess (4) of the extension (5).
Cette rallonge (5) s'accouple à la base par un quatre pans (7) à une noix ou douille qui agit sur la vis à serrer.This extension (5) is coupled at the base by a hexagon (7) to a nut or socket which acts on the screw to be tightened.
Une goupille (6) est fixée près de la base de la rallonge (5) formant une butée verticale à un tube (9) monté libre en rotation sur la rallonge (5) et de même axe que celle-ci.A pin (6) is fixed near the base of the extension (5) forming a vertical stop to a tube (9) mounted to rotate freely on the extension (5) and of the same axis as the latter.
Sur le tube (9) est fixé en sa partie haute un disque gradué (8), et latéralement en partie intermédiaire une tige filetée (10) permettant la fixation d'une tige flexible (11), terminée par un aimant (12) en son extrémité.On the tube (9) is fixed in its upper part a graduated disc (8), and laterally in the intermediate part a threaded rod (10) allowing the fixing of a flexible rod (11), terminated by a magnet (12) in its end.
Cet aimant permet l'immobilisation dans une direction fixe de l'ensemble (8, 9, 10, 11).This magnet allows immobilization in a fixed direction of the assembly (8, 9, 10, 11).
Un anneau (2) de diamètre légèrement supérieur à celui de la tête de la rallonge (5) est muni d'un index de position (3) et d'une vis moletée de blocage (1) rendant solidaire l'anneau -(2) avec la rallonge (5).A ring (2) slightly larger in diameter than that of the head of the extension (5) is provided with a position index (3) and a knurled locking screw (1) making the ring - (2 ) with the extension (5).
L'utilisation de cet outil est simple, on le place sur la vis à serrer, on immobilise l'ensemble (8, 9, 10, 11) à l'aide de l'aimant (12) sur la structure fixe.The use of this tool is simple, it is placed on the screw to be tightened, the assembly (8, 9, 10, 11) is immobilized using the magnet (12) on the fixed structure.
Par la vis moletée (1), on place l'index de position (3) en face du zéro du disque gradué (8), puis on effectue le serrage jusqu'à obtention de l'angle désiré que l'on lira sur le disque gradué (8).Using the knurled screw (1), place the position index (3) in front of the zero of the graduated disc (8), then tighten until the desired angle is obtained, which will be read on the graduated disc (8).
Cet outil pourrait être fourni complet avec les pièces (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) ou sans la rallonge (5) qui est un outil standard et qui peut être transformé grâce au montage de la goupille (6).This tool could be supplied complete with the parts (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) or without the extension (5) which is a standard tool and which can be transformed thanks to the mounting of the pin (6).
D'autre part, les fixations : de l'anneau (2) sur la rallonge, du disque gradué (8) sur le tube (9), et du flexible (11) sur le tube (9) pourrons être modifiées, ceci pour permettre un démontage complet de l'outil. On the other hand, the fixings: of the ring (2) on the extension, of the graduated disc (8) on the tube (9), and of the flexible (11) on the tube (9) can be modified, this for allow complete disassembly of the tool.
