Definitions

  • the pressure fluid is supplied to and discharged from the lock chamber (15) and the release chamber (16), and the pressure receiving area (S1) of the output member (29) is an annular pressure receiving portion of the second piston (8). Is set wider than the pressure receiving area (S2). In this case, the pressing force by which the compressed air in the lock chamber moves the output member upward is greater than the force by which the compressed air in the lock chamber presses the second piston upward. Accordingly, the compressed air in the lock chamber pushes the output member ahead of the second piston.
  • the second piston 8 rises by a predetermined stroke at a low load, leaving the first piston 5 behind. Then, the second piston 8 raises the clamp rod 30 via the compression spring 41. Thereby, the pressing part 40 of the clamp rod 30 is brought into contact with the lower surface of the workpiece W. As a result, the clamp rod 30 is received by the workpiece W, but the second piston 8 is raised against the urging force of the compression spring 41.
  • the first embodiment has the following advantages.
  • the second piston 8 is brought into contact with the workpiece W via the compression spring 41 and the clamp rod 30 before the boost drive of the boost mechanism 20 is started.
  • the clamp rod 30 is connected to the workpiece as compared with the case where the clamp rod is brought into contact with the workpiece in the middle of the boost driving process of the booster mechanism as in the prior art described above. The impact on W can be reduced.
  • the support hole 21 into which the engagement ball 22 is inserted may be penetrated in an oblique direction instead of penetrating the cylinder wall 3a of the guide cylinder 3 in the horizontal direction.
  • the engaging member is not limited to the illustrated engaging ball 22 and may be a member having another shape such as a cylindrical roller.
  • the pressure fluid used in the cylinder device of the present invention may be other compressed gas or liquid such as pressurized oil instead of the exemplified compressed air.
  • the biasing means may be an elastic member such as rubber or resin, or a gas spring, instead of the illustrated compression spring 41.

Abstract

L'invention porte sur un dispositif de cylindre avec un mécanisme d'assistance attaché comportant : un élément de sortie (29) qui est relié à un second piston (8) de façon à être mobile dans la direction axiale et qui fait face au second piston (8) à une distance prescrite (L) dans la direction axiale de façon à être capable d'entrer en contact avec celui-ci ; et un moyen de sollicitation (41), qui est installé entre le second piston (8) et l'élément de sortie (29) et agit dans la direction pour séparer le second piston (8) de l'élément de sortie (29).
