Abstract
CE DISPOSITIF, NOTAMMENT DESTINE A CONTROLER L'INCLINAISON DES EXTREMITES DES RESSORTS, COMPREND DEUX PORTEES 14, 25 DISPOSEES A UN CERTAIN ECARTEMENT MUTUEL ET MONTEES SUR DES ARTICULATIONS DE CARDAN, ET ENTRE LESQUELLES UN RESSORT DE COMPRESSION PEUT ETRE MIS SOUS CONTRAINTE. LES AXES DE LA SUSPENSION DE CARDAN SONT EQUIPES CHACUN D'UN CAPTEUR D'ANGLE DE ROTATION 17, 18; 23, 24 QUI TRANSMET L'INCLINAISON DE LA PORTEE CORRESPONDANTE 14, 25 ET QUI RESULTE DE L'INCLINAISON DE L'EXTREMITE CORRESPONDANTE DU RESSORT A UN ORDINATEUR POUR L'ANALYSE. DE CETTE FACON, ON PEUT MESURER D'UNE FACON RAPIDE, PRECISE ET OBJECTIVE L'INCLINAISON DES EXTREMITES DU RESSORT, AVEC OU SANS CHARGE.THIS DEVICE, IN PARTICULAR INTENDED TO CONTROL THE INCLINATION OF THE SPRING ENDS, INCLUDES TWO SPACES 14, 25 PROVIDED WITH A CERTAIN MUTUAL DISTANCE AND MOUNTED ON CARDAN JOINTS, BETWEEN WHICH A COMPRESSION SPRING CAN BE STRAINED. THE AXLES OF THE CARDAN SUSPENSION ARE EACH EQUIPPED WITH A ROTATION ANGLE SENSOR 17, 18; 23, 24 WHICH TRANSMITS THE INCLINATION OF THE CORRESPONDING RANGE 14, 25 AND WHICH RESULTS FROM THE INCLINATION OF THE CORRESPONDING END OF THE SPRING TO A COMPUTER FOR ANALYSIS. IN THIS WAY, THE INCLINATION OF THE SPRING ENDS, WITH OR WITHOUT LOAD, CAN QUICK, PRECISE AND OBJECTIVE MEASURE.
Description
L'invention prend pour base un dispositif de contrôle pour ressorts deThe invention is based on a control device for springs of
compression. Jusqu'à présent, l'inclinaison des extrémités des ressorts est contrôlée à l'état détendu, par des procédés mécaniques et optiques. Ceci ne peut pas donner d'information sur le comportement d'inclinaison des ressorts sous charge. SeLon l'invention, le dispositif de contrôLe de ressorts de compression, notamment destiné à contrôler l'inclinaison des extrémités d'un ressort, avec ou sans charge, est caractérisé en ce que chacune des deux extrémités du ressort est en appui sur une portée montée par une articulation de Cardan et en ce qu'à chaque articulation de Cardan est associé un capteur d'angle de rotation dont les résultats de mesure sont analysés dans un ordinateur. Ce dispositif présente, comparativement aux dispositifs déjà connus, l'avantage de permettre d'effectuer une mesure rapide, précise et objective de l'inclinaison des extrémités des ressorts à l'état compression. Up to now, the inclination of the ends of the springs has been controlled in the relaxed state, by mechanical and optical methods. This cannot give information on the inclination behavior of the springs under load. According to the invention, the device for controlling compression springs, in particular intended for controlling the inclination of the ends of a spring, with or without load, is characterized in that each of the two ends of the spring is supported on a bearing mounted by a Cardan joint and in that each Cardan joint is associated with a rotation angle sensor whose measurement results are analyzed in a computer. This device has, compared to already known devices, the advantage of making it possible to perform a quick, precise and objective measurement of the inclination of the ends of the springs in the state
tendu et à l'état détendu.tense and relaxed.
Selon une autre caractéristique de l'invention, la portée inférieure peut être bloquée dans une position exactement According to another characteristic of the invention, the lower span can be locked in a position exactly

Le dispositif comprend une plaque de base 10 qui est reliée par plusieurs colonnes verticales 11 à une plaque traverse 12. Un cadre porteur 13 est monté réglable en hauteur sur la plaque de base 10. Une portée 14 est montée sur le cadre porteur par une articulation de Cardan et, plus précisément, dans une double croix 15 dont Les deux axes 15A et 15B qui se croisent touriLLonnent dans le cadre porteur 13. L'axe 15A porte un capteur d'angle de rotation 17, tandis que L'axe 15B, qui porte la portée The device comprises a base plate 10 which is connected by several vertical columns 11 to a transverse plate 12. A support frame 13 is mounted adjustable in height on the base plate 10. A bearing surface 14 is mounted on the support frame by an articulation of Cardan and, more precisely, in a double cross 15, the two axes 15A and 15B of which intersect, rotate in the carrying frame 13. The axis 15A carries a rotation angle sensor 17, while the axis 15B, who carries the litter

La suspension de Cardan supérieure est de construction identique. Elle se trouve dans un cadre porteur 21 qui est monté mobile en translation dans la plaque traverse 12 et sur laquelle agit la charge de contrôLe. La suspension de Cardan comprend une double croix 22 possédant les deux axes 22A et 22B qui se croisent, sur chacun desquels est monté un capteur d'angle de rotation 23 ou 24, respectivement. L'axe 22B est relié à la portée supérieure The upper Cardan suspension is of identical construction. It is located in a support frame 21 which is mounted movable in translation in the cross-plate 12 and on which the control load acts. The Cardan suspension comprises a double cross 22 having the two axes 22A and 22B which intersect, on each of which is mounted a rotation angle sensor 23 or 24, respectively. The axis 22B is connected to the upper span

sur les figures 3 et 4, on a représenté la portée 14. L'inclinaison des extrémités du ressort de compression 20 est transmise aux plateaux 14, 25 constituant les portées. La rotation correspondante des portées 14, 25 si les extrémités du ressort sont inclinées - est transmise à un ordinateur par les capteurs d'angles de rotation 17, 18 et est analysée. Le cadre porteur 13 est réglable en hauteur pour compenser les différences de longueur in Figures 3 and 4, there is shown the bearing surface 14. The inclination of the ends of the compression spring 20 is transmitted to the plates 14, 25 constituting the bearing surfaces. The corresponding rotation of the bearings 14, 25 if the ends of the spring are inclined - is transmitted to a computer by the angle of rotation sensors 17, 18 and is analyzed. The supporting frame 13 is adjustable in height to compensate for the differences in length

L'analyse de l'écart, en grandeur et direction, est assurée par l'utilisation d'un ordinateur. Les portées 14, 25 sont compensées en masse dans la plage de mesure, de sorte qu'il ne se produit pas d'altération des valeurs mesurées. Il est avantageux de prévoir un The analysis of the difference, in size and direction, is ensured by the use of a computer. The ranges 14, 25 are mass compensated in the measuring range, so that there is no alteration of the measured values. It is advantageous to provide a
