Definitions

  • the invention relates to a positioning cylinder particularly for the moving of a welding tool needing a preliminary positioning of this tool which thereafter is being operated by a set of one or more working cylinders.
  • the piston of the positioning cylinder can move axially over a hollow piston rod. Its movement relative to the hollow piston rod is restricted between a step on the piston rod and balls lying in radial holes drilled near the piston rod's end. In their turn the balls move - together with the piston and the hollow piston rod - along the surface of a hollow member having at the end of the stroke a fixing channel wherein the balls sink and said piston locks them, thus immobilizing the hollow piston rod.
  • the advantage of the positioning cylinder according to this invention is that in working position the hollow piston rod locks without any additional moving elements and independently of the working stroke.
  • Fig. 1 shows the positioning cylinder according to the present invention in the initial position, i.e. at the beginning of its movement.
  • Fig. 2 shows the positioning cylinder in intermediate position.
  • Fig. 3 shows the positioning in working position.
  • Fig. 4 shows the cylinder with additional blockings impeding (inhibiting) the rotation of the moving cylinder and the set of working cylinders.
  • a piston (1) moves in the body of the positioning cylinder.
  • the piston 1 starts moving and by pushung the balls 5 moves the hollow piston rod 2 and the set of weld cylinders 12 attached to it (Fig. 2).
  • the balls 5 move along the the hollow member's 7 surface 6, until they reach the groove 8 and sink in it while the piston keeps moving over them until it locks the hollow piston rod 2 to the hollow member 7 (Fig 3)
  • the hollow piston rod 2 can sustain a much greater force than the force, applied by the air pressure on the piston 1.
  • both the working cylinders 12 and the piston rod 13 rotate during service in the hollow piston rod 2 are provided radial pins 9 indented with longitudinal grooves 10 of the hollow member 7 (Fig. 4). Together with the guide 11 fixed to the first working cylinder and comprising longitudinal guiding elements

Abstract

Dans les pistolets à soudure les éléments de déplacement doivent être bloqués après positionnement initial de façon qu'ils ne se rétractent pas lorsque la force de travail est appliquée. Selon l'invention, le piston du cylindre de positionnement peut coulisser sur une tige de piston creux, son déplacement étant limité par un épaulement sur la tige de piston creux et par des billes logées dans des trous radiaux pratiqués à proximité de l'extrémité de la tige. Ces billes, à leur tour, se déplacent le long de la surface d'un élément creux comportant une gorge adéquate à l'extrémité de la course de positionnement, où elles s'enfoncent dans la gorge, le piston glissant par dessus ces billes, bloquant ainsi ensemble la tige de piston creux et l'élément creux.
