Abstract

The present invention relates to a novel application resulting in the torch of a welding robot having a uniform and modulatable oscillatory weaving movement. The novel application employs a device characterised by the use of an adjustable cam 5 which, by means of a rod 4, imparts to an arm 9 integral with the torch carrier 1, a reciprocating longitudinal movement. Such a device, associated with a frame 7 which itself can be adjusted in the same direction, allows both perfect centring of the torch and uniform weaving about this position in terms of amplitude and frequency.

Description

La présente invention concerne un dispositif de balayage pour robot de soudage. The present invention relates to a scanning device for a welding robot.

L'invention est du domaine du soudage automatique par l'intermédiaire de robots:elle porte sur un dispositif permettant å la torche d'avoir un mouvement oscillant régulier ,appelé 11balayage1' ,fonction des caractéristiques du soudage. The invention is in the field of automatic welding by robots: it relates to a device allowing the torch to have a regular oscillating movement, called 11balayage1 ', depending on the characteristics of the welding.

Actuellementsles robots de soudage ne sont pas équipés de systèmes de balayagesmodulable aisément et en même temps robustes et indéréglables.La robustesse est un point capital compte tenu des conditions souvent très dures rencontrées en particulier sur les chantiers volants. Currently, the welding robots are not equipped with easily and at the same time robust and foolproof modular sweeping systems. Robustness is a key point given the often very harsh conditions encountered in particular on flying sites.

La présente invention est l'application nouvelle de moyens connus permettant d'aboutir a un dispositif de balayage réglable et robuste. The present invention is the new application of known means for achieving an adjustable and robust scanning device.

Un porte-torche une fois centré sur la soudure a effectuer (éventuellement par l'intermédiaire d'une crémaillere)est prévu libre de déplacement suivant un axe déterminé.hWelié a un excentrique règlablespar l'intermédiaire d'une tige (l'ensemple constituant un système bielle-manivelle),ledit porte-torche peut ainsi avoir un mouvement alternatif suivant cet axe.L'excentrique étant commandé par un moto-variateur,il est aisi possible de contrdler les caractéristiques de déplacement . de ce porte-torche-amplitude réglable par ltexcentriquesvitesse d'oscillation réglable par le motovariateur.La qualité de la soudure obtenue peut de ce fait etre grandement améliorée. A torch holder once centered on the weld to be carried out (possibly by means of a rack) is provided for free movement along a determined axis. HWelded to an eccentric adjustable by means of a rod (the example constituting a rod-crank system), said torch holder can thus have an alternating movement along this axis. The eccentric being controlled by a motor-variator, it is easy to control the displacement characteristics. of this torch holder-amplitude adjustable by ltexcentrics oscillation speed adjustable by the variable speed drive. The quality of the weld obtained can therefore be greatly improved.

Le dispositif ainsi décrit étant essentiellement mécanique s'accompagne d'une très grande robustesse. The device thus described being essentially mechanical is accompanied by a very great robustness.

Les dessins annexés illustrent l'invention:
La figure 1 représente en coupe le porte-torche (1) pouvant coulisser suivant un axe (2) a 1 'intérieur de profils de guidage (3).Une tige (4) est relée d'une part au porte-torche,d'autre part a un excentrique (5) règlable,l'ensemble tige-excentrique constituant un système bielle-manivelle.Cet excentrique est lui-méme commandé par un motovariateur (6).L'ensemble moto-variateur et excentrique est solidaire du méme bati (7) que les profils de guidage (3).Ce bati peut se régler parallèlement à l'axe (),par l'intermédiaire d'un système crémaillère-vis ou tout autre moyen.The accompanying drawings illustrate the invention:
Figure 1 shows in section the torch holder (1) which can slide along an axis (2) inside the guide profiles (3). A rod (4) is connected on the one hand to the torch holder, d on the other hand has an adjustable eccentric (5), the rod-eccentric assembly constituting a connecting rod-crank system. This eccentric is itself controlled by a variable speed drive (6). The motor-variator and eccentric assembly is integral with the same frame (7) as the guide profiles (3). This frame can be adjusted parallel to the axis (), via a rack-and-bolt system or any other means.

L'application nouvelle selon l'invention aboutit lors du soudage & imprimer à la torche un mouvement oscillatoire parfaitement contrôlé en amplitude et fréquenceqpermettant une excellente qualité de soudure.De plus la robustesse du dispositif employé apporte une fiabilité accrue propice å une meilleure productivité dans les opérations de soudage.  The new application according to the invention results in welding & printing with the torch an oscillatory movement perfectly controlled in amplitude and frequencyq allowing an excellent quality of welding. In addition the robustness of the device used brings increased reliability conducive to better productivity in welding operations.
