Abstract

The clamp is characterised by the combination of a rod (1), in square section steel tube, on to which slides, longitudinally, a head (2) and a block (3), which are also produced from square section steel tube. The head consists of a rotating handle (8), which is extended by a threaded rod (9), which screws into a threaded socket (10), which is fixed to one of the extremities of the rod (1). The block is locked in the required position by means of a pin (12), which fits through the holes provided along the length of the rod and in the block. The head and the block are both equipped with threaded bosses (6), which are designed to receive a moveable jaw, which is held in place by a screw (5). The bosses are designed so that the bearing surface for the jaws is situated above the rod, so that the pieces to be clamped (7), rest entirely on the rod, which forms the base surface.

Description

SERRE-JOINT A MACHOIRES INTERCHANGEABLES
La présente invention a pour objet un serrejoint à mâchoires interchangeables.INTERCHANGEABLE JAW CLAMP
The present invention relates to a clamp with interchangeable jaws.

I1 peut convenir pour le serrage de très nombreux types de pièces, mais est surtout destiné à des applications en menuiserie ou ébénisterie et en particulier pour effectuer le collage de pièces présentant des surfaces devant être parfaitement alignées. I1 can be suitable for clamping many types of parts, but is especially intended for applications in carpentry or cabinetmaking and in particular for bonding parts with surfaces to be perfectly aligned.

Les dispositifs réalisés à ce jour sont le plus souvent des appareils encombrants comportant des mors inamovibles nécessitant l'utilisation d'une série d'accessoires pour pouvoir s'adapter aux différents types de pièces à serrer et pour éviter de marquer ces dernières. Ils ne permettent en général pas l'empilage des assemblages collés en cours de séchage ce qui entraîne la nécessité d'un espace de stockage important en cas de fabrication en série. The devices produced to date are most often bulky devices comprising irremovable jaws requiring the use of a series of accessories in order to be able to adapt to the different types of parts to be clamped and to avoid marking them. They generally do not allow the stacking of bonded assemblies during drying, which leads to the need for a large storage space in the case of mass production.

L'invention a pour but de remédier à ces inconvénients. Il ne nécessite en effet aucun dispositif supplémentaire nécessaire dans la majorité des cas pouvant se présenter et assure un serrage précis et efficace grâce à une répartition de l'effort sur des mors de serrage de plus de 200 mm de longueur, tout en ne risquant pas de glisser ou d'abîmer la surface des pièces à serrer. I1 permet en outre d'empiler aisément les assemblages à coller en cours de séchage et présente un appui parfaitement plan constituant une surface de référence pour les pièces à assembler.  The invention aims to remedy these drawbacks. In fact, it does not require any additional device necessary in the majority of the cases that can arise and ensures precise and effective tightening thanks to a distribution of the force on clamping jaws of more than 200 mm in length, while not risking slipping or damaging the surface of the parts to be clamped. It also makes it easy to stack the assemblies to be bonded during drying and has a perfectly flat support constituting a reference surface for the parts to be assembled.

I1 est constitué d'un tube acier de section carrée, sur lequel coulissent deux éléments tubulaires également en acier et de section carrée comportant chacun un mors amovible disposé de manière à ce que les pièces à serrer reposent entierement sur le tube interne formant une surface de référence permettant l'alignement des pièces à assembler, l'un des éléments coulissants comportant une poignée de serrage rotative équipée d'un embout de section hexagonale permettant un serrage par clé, les mors étant de préférence constitués de tiges cylindriques revêtues de manchons en matière synthétique semi-rigide. I1 consists of a steel tube of square section, on which two tubular elements also of steel and of square section slide, each comprising a removable jaw arranged so that the parts to be clamped rest entirely on the internal tube forming a surface of reference allowing the alignment of the parts to be assembled, one of the sliding elements comprising a rotary tightening handle equipped with a hexagonal section end piece allowing tightening by key, the jaws preferably being made up of cylindrical rods coated with sleeves of material semi-rigid synthetic.

Sur les dessins annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention:
la figure 1 représente le dispositif dans son ensemble, vu de côté,
la figure 2 montre dans les mêmes conditions le dispositif vu de dessus,
la figure 3 est une coupe partielle longitudinale agrandie de la tête, suivant les flèches A
A de la figure 2,
les figures 4 et 5 sont des vues de côté partielles montrant des montages particuliers des mors standards,
la figure 6 représente dans les mêmes conditions un serre-joint équipé de mors spéciaux
et les figures 7 et 8 représentent, respectivement vu de dessus et en bout, un système de mors permettant le serrage de pièces dépourvues de surfaces planes.In the accompanying drawings, given by way of nonlimiting examples of embodiments of the subject of the invention:
FIG. 1 represents the device as a whole, seen from the side,
FIG. 2 shows the device seen from above under the same conditions,
Figure 3 is an enlarged partial longitudinal section of the head, along the arrows A
A of figure 2,
FIGS. 4 and 5 are partial side views showing particular arrangements of the standard jaws,
Figure 6 shows under the same conditions a clamp equipped with special jaws
and Figures 7 and 8 show, respectively seen from above and at the end, a jaw system allowing the clamping of parts devoid of planar surfaces.

Le dispositif, figures à 8, est constitué d'une canne 1 en tube acier de section carrée, sur laquelle sont montés une tête 2 et un patin 3 constitués tous deux d'éléments tubulaires, également en acier et de section carrée, dont les dimensions sont déterminées pour qu'ils puissent coulisser longitudinalement avec un faible jeu sur la canne 1. Ces deux éléments reçoivent chacun un mors amovible 4 maintenus par des vis 5 sur deux bossages 6 taraudés fixés respectivement sur la tête 2 et sur le patin 3 de telle manière que la surface d'appui des mors se trouve au-dessus de la canne 1 et non des éléments tubulaires coulissants. Cette disposition permet aux pièces à serrer 7 de reposer entièrement sur la canne qui joue ainsi le rôle de surface de référence assurant par exemple l'alignement d'objets à coller. The device, Figures 8, consists of a rod 1 made of steel tube of square section, on which are mounted a head 2 and a shoe 3 both made of tubular elements, also made of steel and of square section, the dimensions are determined so that they can slide longitudinally with little play on the rod 1. These two elements each receive a removable jaw 4 held by screws 5 on two tapped bosses 6 fixed respectively on the head 2 and on the pad 3 of such that the jaw bearing surface is above the rod 1 and not the sliding tubular elements. This arrangement allows the parts to be clamped 7 to rest entirely on the rod which thus plays the role of reference surface ensuring for example the alignment of objects to be glued.

La tête 2 comporte une poignée rotative 8 de serrage prolongée par une tige filetée 9 passant à l'intérieur de la tete et se vissant dans une douille taraudée 10 fixée à l'une des extrémités de la canne 1. The head 2 comprises a rotary handle 8 for tightening extended by a threaded rod 9 passing inside the head and screwing into a threaded socket 10 fixed to one of the ends of the rod 1.

Cette tige filetée est équipée, côté poignée rotative d'un embout 11 de section hexagonale permettant d'effectuer le serrage à l'aide d'une clé, le cas échéant de type dynamométrique.This threaded rod is fitted, on the rotary handle side, with an end piece 11 of hexagonal section allowing tightening to be carried out using a wrench, if necessary of the dynamometric type.

Des trous disposés le long de la canne 1 et sur le patin 3 permettent de.fixer ce dernier à la position correspondant à l'écartement des mors au moyen d'une cheville 12. Cette opération est facilitée par une graduation 13 en centimètres prévue sur la face supérieure de la canne 1. Holes arranged along the rod 1 and on the pad 3 allow the latter to be fixed in the position corresponding to the spacing of the jaws by means of a dowel 12. This operation is facilitated by a graduation 13 in centimeters provided on the upper face of the rod 1.

Le mors standard est constitué d'une tige métallique 4 de section circulaire comportant un trou central permettant le passage de la vis 5 de fixation et, de part et d'autre, un manchon 14 en matière plastique semi-rigide, telle que le polychlorure de vinyle, empêchant la pièce à serrer 7 de glisser sans risquer de la détériorer. The standard jaw consists of a metal rod 4 of circular section comprising a central hole allowing the passage of the fixing screw 5 and, on either side, a sleeve 14 of semi-rigid plastic, such as polychloride of vinyl, preventing the workpiece 7 from sliding without risk of damaging it.

La conception du serre-joint selon l'invention permet d'adapter aisément les mors aux éléments à serrer. The design of the clamp according to the invention makes it possible to easily adapt the jaws to the elements to be clamped.

Pour les pièces épaisses, il est possible de monter deux mors 4 superposés en interposant entre eux une noix 15 de forme appropriée prévue à cet effet (figure 4).For thick pieces, it is possible to mount two superimposed jaws 4 by interposing between them a nut 15 of suitable shape provided for this purpose (Figure 4).

Dans une variante d'exécution, la tête 2 et le patin coulissant 3 comportent chacun deux bossages 6 taraudés opposés permettant ainsi de monter deux jeux de mors 4 de part et d'autre du serre-joint (figure 5). In an alternative embodiment, the head 2 and the sliding shoe 3 each have two opposing threaded bosses 6 thus making it possible to mount two sets of jaws 4 on either side of the clamp (FIG. 5).

Des mors spécifiques peuvent être réalisés pour des applications particulières. Ils pourront par exemple être constitués de plaques métalliques 16 fixées sur des embases 17, elle-mêmes montées sur les bossages 6 au moyen de vis 5 (figure 6). Specific jaws can be produced for particular applications. They may for example consist of metal plates 16 fixed on bases 17, themselves mounted on the bosses 6 by means of screws 5 (Figure 6).

Pour le serrage de pièces ne présentant pas de surfaces d'appui planes, il sera utilisé des plaques perforées 18 comportant une rainure 19 en V le long de l'un de leurs côtés, ainsi que des éléments de serrage 20 à position ajustable constitué d'une partie cylindrique recouverte, comme les mors standards, d'un manchon en matière plastique semi-rigide. For clamping parts that do not have flat bearing surfaces, perforated plates 18 having a V-shaped groove 19 along one of their sides will be used, as well as clamping elements 20 with adjustable position consisting of '' a cylindrical part covered, like standard jaws, with a semi-rigid plastic sleeve.

Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
