Description

La présente invention concerne la mise au point mécanique ou électroniques pour des réglages initiaux selon des instructions techniques et est relative à un tournevis de réglage destiné à permettre cette mise au point, cf. par example US-A-2 800 281.The present invention relates to mechanical or electronic focusing for initial adjustments according to technical instructions and relates to an adjustment screwdriver intended to allow this adjustment, cf. for example US-A-2 800 281.

Le but de l'invention est, par exemple, de relever le réglage d'une vis de façon très précise avant un démontage et de repositionner exactement ladite vis lors du remontage.The object of the invention is, for example, to note the adjustment of a screw very precisely before dismantling and to reposition said screw exactly during reassembly.

Pour atteindre ce but il a paru avantageux de créer un tournevis de réglage compte-tours, pourvu d'une lame sertie dans un manche, caractérisé en ce que sur la queue de la lame est montée de manière mobile une pièce tubulaire susceptible de se déplacer dans un évidement du manche recevant la queue de la lame, le manche étant gradué sur son pourtour à l'entrée de l'évidement et la pièce mobile portant une double graduation sur au moins une partie de sa longueur, chaque graduation s'étendant en sens inverse par rapport à l'autre.To achieve this goal it seemed advantageous to create a tachometer adjustment screwdriver, provided with a blade crimped in a handle, characterized in that on the tail of the blade is movably mounted a tubular part capable of moving in a recess in the handle receiving the tail of the blade, the handle being graduated on its periphery at the entrance to the recess and the moving part carrying a double graduation over at least part of its length, each graduation extending in opposite direction to each other.

Pour mieux faire comprendre l'invention celle-ci est décrite maintenant avec plus de détails sur la base du dessin annexé, à titre d'exemple uniquement, montrant en :

  • Figure 1 une vue en plan d'un tournevis de réglage suivant l'invention, et
  • Figure 2 une coupe longitudinale dans le tournevis de réglage de figure 1.
To better understand the invention, it is now described in more detail on the basis of the attached drawing, by way of example only, showing in:
  • FIG. 1 a plan view of an adjustment screwdriver according to the invention, and
  • Figure 2 a longitudinal section in the adjustment screwdriver of Figure 1.

Un tournevis de réglage compte-tours réalisé conformément à l'invention comporte en plus de la lame 1 et du manche 2, dans lequel est sertie la queue 1' de la lame 1 en 3, une pièce tubulaire 4 montée de manière mobile sur la lame 1 et insérée au moins partiellement dans la partie antérieure élargie 5' de l'évidement 5 prévu dans le manche 2 pour la queue 1' de la lame 1.A tachometer adjustment screwdriver produced in accordance with the invention comprises, in addition to the blade 1 and the handle 2, in which the shank 1 ′ of the blade 1 in 3 is crimped, a tubular piece 4 movably mounted on the blade 1 and inserted at least partially into the enlarged front part 5 'of the recess 5 provided in the handle 2 for the shank 1' of the blade 1.

La pièce mobile 4 est filetée intérieurement pour pouvoir se déplacer sur la queue également filetée 1' de la lame 1 et elle est pourvue longitudinalement d'une double graduation 6, 6', chaque graduation allant en sens inverse par rapport à l'autre.The movable part 4 is internally threaded in order to be able to move on the tail also threaded 1 'of the blade 1 and it is provided longitudinally with a double graduation 6, 6', each graduation going in opposite direction with respect to the other.

Au dessin on a représenté une double graduation de 0 à 20 et chaque indication correspond à un tour complet du manche 2, respectivement de la lame 1, Donc, ici cela correspond à une possibilité de réglage de vingt tours maximum.In the drawing there is shown a double graduation from 0 to 20 and each indication corresponds to a full turn of the handle 2, respectively of the blade 1, So here this corresponds to a possibility of adjustment of twenty turns maximum.

De son côté, le manche 2 porte sur son pourtour à l'entrée de l'évidement 5' une graduation 7 divisant ledit pourtour en trente deux parties égales, les indications 1/4, 1/2, 3/4 apparaissant compte tenu des deux sens possibles de rotation. A chaque indication 1/4 correspond une indication 3/4 et inversément de couleurs différentes les sens de rotation étant représentés par des flèches 8, 8' de couleur correspondante.For its part, the handle 2 carries on its periphery at the entrance to the recess 5 'a graduation 7 dividing said periphery into thirty two equal parts, the indications 1/4, 1/2, 3/4 appearing taking into account of the two possible directions of rotation. Each 1/4 indication corresponds to a 3/4 indication and vice versa of different colors, the directions of rotation being represented by arrows 8, 8 ′ of corresponding color.

La lame 1 est pourvue d'une butée de fin de course coulissant 9 pour la pièce mobile 4 à l'opposé du manche 2. Cette butée 9 peut être déplacée sur la lame 1 présentant un plat, sur lequel est serrée une vis de blocage de la butée pour maintenir celle-ci à l'emplacement choisi. De son côté, le fond de la partie élargie 5' de l'évidement 5 sert de butée fin de course pour la pièce mobile 4 dans son déplacement à l'opposé de la lame 1.The blade 1 is provided with a sliding end stop 9 for the movable part 4 opposite the handle 2. This stop 9 can be moved on the blade 1 having a flat, on which a locking screw is tightened of the stopper to maintain it at the chosen location. For its part, the bottom of the enlarged part 5 ′ of the recess 5 serves as a limit stop for the moving part 4 in its movement opposite the blade 1.

L'utilisation d'un tournevis de réglage compte-tours suivant l'invention est simple, rapide et efficace. Lors de chaque opération réclamant soit le serrage, soit le désserrage d'une vis de réglage il est important de dévisser, respectivement de visser à fond la pièce mobile graduée 4 en veillant à la mise à zéro parfaite de l'instrument, c'est-àdire de veiller à ce que la ligne de repère 10 sur la pièce mobile 4 soit en regard de l'indication 0 du manche 2, lorsque ladite pièce 4 est à fond de course, à gauche ou à droite selon le dessin.Using a tachometer adjusting screwdriver according to the invention is simple, quick and effective. During each operation requiring either the tightening or the loosening of an adjustment screw, it is important to unscrew and screw the graduated moving part 4 fully, respectively, ensuring that the instrument is set to zero. - ie to ensure that the reference line 10 on the moving part 4 is opposite the indication 0 of the handle 2, when said part 4 is at full travel, to the left or to the right according to the drawing.

Pour le relevé d'un réglage, il faut dévisser la pièce mobile graduée 4, comme indiqué ci-dessus, tenir d'une main ladite pièce 4 par sa partie moletée 4' et serrer la vis de réglage (non représentée) à fond en faisant pivoter le manche 2 du tournevis vers la droite de l'autre main. La lecture faite alors sur la pièce mobile 4 donne le nombre de tours complets et la lecture sur la graduation du manche donne la fraction de tour à ajouter, la butée coulissante 9 devant dans ce cas se trouver à fond de course, vers la gauche selon le dessin.To record an adjustment, you must unscrew the graduated moving part 4, as indicated above, hold said part 4 by its knurled part 4 'with one hand and tighten the adjustment screw (not shown) as far as it will go. rotating the handle 2 of the screwdriver to the right with the other hand. The reading then made on the moving part 4 gives the number of complete turns and the reading on the graduation of the handle gives the fraction of a turn to add, the sliding stop 9 in this case must be at the bottom of the stroke, to the left according to the drawing.

Si la vis de réglage démontée doit être remontée suivant le même réglage, il suffit de la revisser à fond et ensuite de la desserrer jusqu'à fin de course de la pièce mobile graduée 4, qui se retrouvera alors à sa position de départ.If the disassembled adjustment screw must be reassembled according to the same adjustment, it is sufficient to screw it back in fully and then loosen it until the end of travel of the graduated moving part 4, which will then return to its starting position.

Pour une mise au point initiale, avec la vis de réglage vissée à fond et la pièce mobile graduée 4 dévissée à fond comme indiqué ci-dessus - la butée coulissante 9 devant se trouver à fond de course, vers la gauche selon le dessin - il suffit de revisser ladite pièce 4 du nombre de tours, et éventuellement d'une fraction de tour, correspondant aux indications de la documentation technique du réglage à réaliser, de maintenir la partie moletée 4' d'une main et de devisser la vis de réglage en faisant pivoter le manche 2 de l'autre main dans le sens de la flèche 8' jusqu'à ce que butée 9 vienne en contact avec la pièce mobile 4.For an initial adjustment, with the adjusting screw screwed in fully and the graduated moving part 4 unscrewed fully as indicated above - the sliding stop 9 must be at the bottom of the stroke, to the left according to the drawing - it just screw said part 4 back by the number of turns, and possibly a fraction of a turn, corresponding to the indications in the technical documentation of the adjustment to be made, hold the knurled part 4 'with one hand and unscrew the adjustment screw by rotating the handle 2 with the other hand in the direction of the arrow 8 'until the stop 9 comes into contact with the moving part 4.

Lorsqu'un même réglage doit s'effectuer de manière répétée, la pièce mobile graduée 4 est vissée à fond puis dévissée du nombre de tours et éventuellement d'une fraction de tours correspondant au réglage demandé et la butée coulissante 9 est déplacée jusqu'à venir en contact avec ladite pièce 4.When the same adjustment has to be made repeatedly, the graduated moving part 4 is screwed in fully then unscrewed by the number of turns and possibly by a fraction of turns corresponding to the requested adjustment and the sliding stop 9 is moved to come into contact with said part 4.

Le réglage peut alors s'effectuer de la manière suivante :

  • 1. La pièce 4 vissée à fond et la vis de réglage vissée à fond.
  • 2. La lame du tournevis étant engagée dans la vis, maintenir d'une main la partie moletée 4' de la pièce 4 et dévisser la vis de réglage en faisant pivoter le manche 2 de l'autre main dans le sens de la flèche 8', jusqu'à ce que la butée coulissante 9 entre en contact avec la pièce 4.
  • 3. Pour un même réglage, revisser la pièce mobile 4 et répéter l'opération décrite aux points 1 et 2.
The adjustment can then be carried out as follows:
  • 1. Part 4 fully screwed and the adjusting screw screwed thoroughly.
  • 2. The blade of the screwdriver being engaged in the screw, hold in one hand the knurled part 4 'of the part 4 and unscrew the adjusting screw by rotating the handle 2 with the other hand in the direction of the arrow 8 ', until the sliding stop 9 comes into contact with the part 4.
  • 3. For the same adjustment, screw on the moving part 4 and repeat the operation described in points 1 and 2.

Bien entendu, un tournevis de réglage compte-tours suivant l'invention peut être réalisé en diverses dimensions et avec diverses graduations.Of course, a tachometer adjusting screwdriver according to the invention can be produced in various dimensions and with various graduations.
