Abstract

Precision displacement device for a member along a trajectory. A fixed member 1 is provided with a plurality of pairs of runners 3, 4 spaced out by a pitch P which are spaced within each pair by a distance d which is equal, within the operational play, to the thickness of the screw thread 11 of a screw 10 which engages between the runners 3, 4 of at least one pair, this screw 10 being mounted and rotatably driven on a movable member 8 sliding freely along slides 6 parallel to the fixed member 1.

Description

t'invention a pour objet un dispositif qui permet de déplacer avec précision un organe le long d'une trajectoire rectiligne ou curviligne. The invention relates to a device which makes it possible to precisely move an organ along a rectilinear or curvilinear trajectory.

On rencontre fréquemment dans les machines automatiques, par exemple-dans les manipulateurs et dans les robots, la nécessité de déplacer un organe, par exemple un bras terminé par une pince de préhension, le long d'une trajectoire avec une grande précision sous le contrôle de signaux qui sont fournis par un moyen de commande approprie. Frequently encountered in automatic machines, for example in manipulators and in robots, the need to move an organ, for example an arm terminated by a gripper, along a trajectory with great precision under control of signals which are supplied by an appropriate control means.

Un moyen classique comme un couple pignon-crémaillèrE n'est pas satisfaisant parce qu'il est couteux et parce qu'il oçporte un jeu qui nuit à la précision. Un autre moyen classique comme le couple écrou-tige filetée ne convient pas non plus parce qu'il comporte aussi un jeu et parce qu'il est difficile d'empêcher la vis de vibrer ou de fouetter dès qu'elle atteint une certaine longueur. A conventional means such as a rack and pinion couple is not satisfactory because it is expensive and because it involves a game which impairs precision. Another conventional means such as the threaded nut-rod couple is also unsuitable because it also has a play and because it is difficult to prevent the screw from vibrating or whipping as soon as it reaches a certain length.

Le but principal de l'invention est de parvenir à un dispositif de déplacement d'un organe le long d'une trajectoire avec une grande précision, sans jeu nuisible, sur une longueur illimitée qui ne risque pas d'être restreinte par des inconvénients de fonctionnement. The main object of the invention is to achieve a device for moving an organ along a trajectory with great precision, without harmful play, over an unlimited length which is not likely to be restricted by drawbacks of operation.

Un dispositif conforme à l'invention comprend un organe allongé, rigide, fixe, pourvu sur une face le long d'une ligne déterminée d'une pluralité de paires de galets libres en rotation. Les deux galets de chaque paire sont espacés d'une distance précise d et les paires de galets sont espacées d'un pas P précis
Un moyen de guidage est supporté parallèlement à la face de l'organe fixe munie des galets. Un organe mobile est monté coulissant sur ce moyen de guidage et pourvu d'une vis entrainée en rotation par un moteur supporté par cet organe mobile. Cette vis a un filet de vis à profil rectangulaire d'épaisseur d et de longueur supérieure à PO Ce filet s'engage successivement entre les galets de chaque paire ; il est toujours engagé entre les galets d1une paire au moins. Le pas P est donc un multiple entier du pas de la vis.A device according to the invention comprises an elongated, rigid, fixed member, provided on one face along a determined line with a plurality of pairs of free rotating rollers. The two rollers of each pair are spaced by a precise distance d and the pairs of rollers are spaced by a precise pitch P
A guide means is supported parallel to the face of the fixed member provided with rollers. A movable member is slidably mounted on this guide means and provided with a screw driven in rotation by a motor supported by this movable member. This screw has a screw thread with a rectangular profile of thickness d and of length greater than PO. This thread engages successively between the rollers of each pair; it is always engaged between the rollers of at least one pair. The pitch P is therefore an integer multiple of the pitch of the screw.

A chacune de ses extrémités opposées, le filet de vis est aminci en épaisseur. At each of its opposite ends, the screw thread is thinned in thickness.

De préférence les galets libres en rotation ont une surface légèrement bombée. Preferably the free rotating rollers have a slightly curved surface.

Le moyen de guidage peut être d'un type quelconque déterminé ; on peut utiliser par exemple des glissières cylindriques convenablement supportées par des moyens appropriés qui peuvent être supportés eux-mêmes par l'organe rigide fixe. The guide means can be of any determined type; one can use for example cylindrical slides suitably supported by suitable means which can be supported themselves by the fixed rigid member.

Pour bien faire comprendre l'invention et ses avantages, on donnera maintenant une description d'un mode préféré de réalisation , sans intention limitative et sans exclure aucune variante entrant dans la définition de 1'invention. In order to clearly understand the invention and its advantages, a description will now be given of a preferred embodiment, without limiting intention and without excluding any variant coming within the definition of the invention.

On se reportera au dessin annexé dans lequel
- la figure 1 est une vue générale de dessus d'un dispositif conforme à l'invention,
- la figure 2 est une vue agrandie de détail montrant la vis engagée avec deux paires de galets.Reference is made to the appended drawing in which
FIG. 1 is a general top view of a device according to the invention,
- Figure 2 is an enlarged detail view showing the screw engaged with two pairs of rollers.

Le dispositif de l'invention comprend un organe allongé 1, rigide, fixe qui peut faire partie d'une structure quelconque plus importante. On réalise facilement l'organe 1 à partir d'une pièce tubulaire quelconque du commerce. Il n'est pas nécessaire qu'elle possède des dimensions précises. The device of the invention comprises an elongate member 1, rigid, fixed which can be part of any larger structure. The member 1 is easily produced from any commercial tubular part. It does not have to have precise dimensions.

Sur une face 2 de l'organe 1, le long d'une ligne déterminée sont montés par paires des galets 3 - 4 libres de rotation chacun autour d'un axe 5 La face 2 n'a pas besoin d'avoir des qualités précises de planéité. Il est suffisant, selon l'invention, que les axes 5 des galets 3, 4 soient fixés à l'organe 1 en des points déterminés avec une précision de 0,01 mm au moins. Cette condition est facilement observée à l'aide des machines modernes à pointer, à percer ou à fraiser à commande numérique. Chaque axe 5 peut être fileté pawtiellement et vissé dans un trou taraudé; de préférence, quand organe fixe 1 est tubulaire, chaque axe 5 peut être traversé par un boulon de montage.On a face 2 of the member 1, along a determined line are mounted in pairs of rollers 3 - 4 free to rotate each around an axis 5 The face 2 does not need to have precise qualities flatness. It is sufficient, according to the invention, that the axes 5 of the rollers 3, 4 are fixed to the member 1 at determined points with an accuracy of at least 0.01 mm. This condition is easily observed with the help of modern numerically controlled punching, drilling or milling machines. Each axis 5 can be threaded pawtially and screwed into a tapped hole; preferably, when the fixed member 1 is tubular, each axis 5 can be crossed by a mounting bolt.

Dans une paire de galets 3-4, les galets sont séparés par une distance d et les paires successives de galets 3-4 sont espacées d'un pas P mesuré entre les points médians de la distance d entre deux galets 3-4 de deux paires se succédant. L'implantation précise des axes 5 des galets permet d'obtenir un pas P précis. In a pair of rollers 3-4, the rollers are separated by a distance d and the successive pairs of rollers 3-4 are spaced apart by a pitch P measured between the midpoints of the distance d between two rollers 3-4 by two succeeding pairs. The precise location of the axes 5 of the rollers makes it possible to obtain a precise pitch P.

Un moyen de guidage approprié 6 est supporté parallèlement à la face 2 de l'organe fixe 1. On peut utiliser par exemple une ou plusieurs glissières cylindriques ou d'autres types équivalents de glissières Ce moyen de guidage 6 est supporté par tout moyen convenable. Par exemple, des consoles 7 peuvent s'étendre à partir de l'organe rigide fixe 1, mais cette disposition n'est pas obligatoire du moment que le moyen de guidage 6 est convenablement soutenu parallèlement à la face 2 de l'organe 1. A suitable guide means 6 is supported parallel to the face 2 of the fixed member 1. One or more cylindrical slides or other equivalent types of slides can be used, for example. This guide means 6 is supported by any suitable means. For example, consoles 7 may extend from the fixed rigid member 1, but this arrangement is not compulsory as long as the guide means 6 is suitably supported parallel to the face 2 of the member 1.

Un organe mobile 8 est monté coulissant librement le long du moyen de guidage 6. Cet organe constitue par luimême, ou il supporte, toute pièce ou tout moyen que l'on désire déplacer avec précision sur une course quelconque ou arrêter en plusieurs points précis. A movable member 8 is mounted to slide freely along the guide means 6. This member constitutes by itself, or it supports, any part or any means which it is desired to move with precision over any race or to stop at several precise points.

Sur l'organe mobile 8 est montée libre en rotation, à l'aide de paliers 9, une vis 10 qui a un filet 11 à profil rectangulaire d'épaisseur d. Les parties extrêmes terminales opposées 12 du filet de vis 11 sont progressivement amincies à partir de leur épaisseur d. La longueur de la vis 10 est supérieure au pas P des paires de galets 3-4. On the movable member 8 is mounted to rotate freely, using bearings 9, a screw 10 which has a thread 11 with a rectangular profile of thickness d. The opposite end end portions 12 of the screw thread 11 are progressively thinned from their thickness d. The length of the screw 10 is greater than the pitch P of the pairs of rollers 3-4.

La vis 10 est entrainée en rotation par exemple à l'aide d'une première poulie crantée 13, d'une courroie crantée- 14, d'une seconde poulie crantée 15 calée sur l'arbre d'un moteur 16 porté par l'organe mobile 8. Tout autre moyen équivalent d'-entrainement en rotation de la vis 10 pourrait être utilisé. The screw 10 is driven in rotation for example using a first toothed pulley 13, a toothed belt 14, a second toothed pulley 15 wedged on the shaft of an engine 16 carried by the movable member 8. Any other equivalent means of driving the screw 10 in rotation could be used.

Le filet de vis 11 est toujours engagé entre deux galets 3-4 d'une paire au moins de ces derniers. La rotation de la vis 10 provoque le déplacement de l'organe mobile 8 qui coulisse le long du moyen de guidage 6. La position des galets 3-4 ayant été fixée avec précision, le déplacement est lui-même très précis. Le filet 11 s'engage par son extrémité amincie entre les galets 3-4 d'une paire suivante de galets avant de quitter la paire précédente. The screw thread 11 is always engaged between two rollers 3-4 of at least one pair of the latter. The rotation of the screw 10 causes the displacement of the movable member 8 which slides along the guide means 6. The position of the rollers 3-4 having been fixed with precision, the displacement is itself very precise. The thread 11 engages by its thinned end between the rollers 3-4 of a next pair of rollers before leaving the previous pair.

On peut voir sur la figure 2 qu'un codeur optique 17 est calé en rotation avec la vis 10, au-delà de la première poulie 13. Il fait partie d'un moyen classique de comptage numérique qui permet de commander et de contrôler avec précision la position et la course de l'organe mobile. Une telle mesure précise de la position d'un organe mobile nécessite de disposer d'un moyen de déplacement précis de ce même organe mobile. C'est ce que réalise le dispositif de l'invention qui fonctionne avec un jeu maximum de O,02 mm. Les galets 3-4 de chaque paire de galets sont espacés d'une distance précise d qui découle de leur diamètre et de la distance des axes 5. It can be seen in FIG. 2 that an optical encoder 17 is locked in rotation with the screw 10, beyond the first pulley 13. It is part of a conventional digital counting means which makes it possible to command and control with precision the position and the stroke of the movable member. Such a precise measurement of the position of a movable member requires having a means of precise movement of this same movable member. This is what the device of the invention achieves, which operates with a maximum clearance of 0.02 mm. The rollers 3-4 of each pair of rollers are spaced by a precise distance d which results from their diameter and from the distance from the axes 5.

Cette distance d est égale à l'épaisseur du filet de 11 plus un jeu théorique de 0,01 mm qui peut, en pratique, atteindre 0,02 mm comme on vient de le dire.This distance d is equal to the thickness of the thread of 11 plus a theoretical clearance of 0.01 mm which can, in practice, reach 0.02 mm as we have just said.

Dans un dispositif réalisé conformément à l'invention, le filet de vis Il avait une épaisseur de 4 mm et le pas p entre les paires de galets était de 160 mm. Les galets avaient un diamètre de 16 mm. In a device produced in accordance with the invention, the screw thread II had a thickness of 4 mm and the pitch p between the pairs of rollers was 160 mm. The rollers had a diameter of 16 mm.

Aucune prescription particulière ne s'impose à l'exé- cution de la vis 10 sauf qu'elle doit avoir un pas assez faible qui la rend irréversible . Dans l'exemple cité ici, ce pas était de 20 mm avec un diamètre extérieur sur filet de 100 mm. No particular requirement is imposed on the execution of the screw 10 except that it must have a sufficiently small pitch which makes it irreversible. In the example cited here, this pitch was 20 mm with an outside diameter on a thread of 100 mm.

L'organe mobile 8 était déplacé par la vis 10 à une vitesse de 0,5 m/s après une période d'accélération à chaque démarrage de 0,5 s.The movable member 8 was moved by the screw 10 at a speed of 0.5 m / s after an acceleration period at each start of 0.5 s.

On remarquera que le dispositif de l'invention n'exige un usinage de grande précision que sur des surfaces de dimensions réduites : le filet de vis 11 et les galets 3-4 l'implantation des paires de galets 3-4 doit également être précise mais elle se fait par pointage, comme on l'a expliqué
Il n'est pas utile que la face 2 de l'organe fixe l soit usinée avec précision ; il suffit qu'elle soit dressée pour permettre l'exécution précise des trous de montage des galets 3-4. Par exemple, il est avantageux d'utiliser un profilé tubulaire à profil carré ou rectangulaire que l'on attache solidement à une structure fixe. Il est plus facile ensuite de monter les galets 3-4 à l'aide de boulons qui traversent la paroi de ce profilé comme on l'a montré sur la figure 2.It will be noted that the device of the invention requires high-precision machining only on surfaces of reduced dimensions: the screw thread 11 and the rollers 3-4 the location of the pairs of rollers 3-4 must also be precise. but it is done by pointing, as we explained
It is not useful for the face 2 of the fixed member 1 to be machined with precision; it only needs to be erected to allow precise execution of the mounting holes for the rollers 3-4. For example, it is advantageous to use a tubular profile with a square or rectangular profile that is securely attached to a fixed structure. It is then easier to mount the rollers 3-4 using bolts which pass through the wall of this profile as shown in Figure 2.

La longueur du trajet le long duquel on déplace l'organe mobile 8 n'est pas limitée par des difficultés de réalisation ni par des inconvénients de fonctionnement. Dans l'exemple décrit ci-dessus, le trajet est rectiligne. Il est à noter qu'un trajet curviligne est également possible. The length of the path along which the movable member 8 is moved is not limited by production difficulties or by operating disadvantages. In the example described above, the path is straight. It should be noted that a curvilinear route is also possible.

Il suffit que l'incurvation permette de réaliser une vis à profil convexe ou concave ayant un filet capable de s'engager entre les galets 3-4 des paires successives de galets.It suffices that the bending makes it possible to produce a screw with a convex or concave profile having a thread capable of engaging between the rollers 3-4 of successive pairs of rollers.

Les galets peuvent être des galets suiveurs de came, que l'on trouve dans le commerce, avec une face extérieure légèrement bombée, rectifiés avec précision. Quand on utilise des aciers, ou d'autres matériaux, de grande dureté, le dispositif de l'invention est extrêmement peu sujet à usure puisque les galets 3-4 roulent sur le filet 11 de la vis 10.  The rollers can be cam follower rollers, which are commercially available, with a slightly curved outer face, precision ground. When steels or other materials of great hardness are used, the device of the invention is extremely subject to wear since the rollers 3-4 roll on the thread 11 of the screw 10.
