Definitions

  • the two rotation degree of freedom mechanism 3 of this embodiment is configured by a pan and tilt mechanism.
  • the rotation two degrees of freedom mechanism 3 includes a proximal end member 3a fixed to the installation surface 7a, and a first rotary member 3c rotatable about the rotational axis C1 with respect to the proximal end member 3a.
  • a second rotary member 3d rotatable about a rotational axis C2 with respect to the first rotary member 3c and a distal end side member 3b fixed to the second rotary member 3d are provided.
  • Condition 1 The angle and the length of the central axis O1 of the rotational couple of the link hub 12 (13) and the end link member 15 (16) in each link mechanism 14 are equal to each other on the proximal end side and the distal end side.
  • Condition 2 at the proximal end and at the distal end, the central axis O1 of the rotational couple of the link hub 12 (13) and the end link member 15 (16), the end link member 15 (16) and the central link member 17
  • the central axis O2 of the rotational couple intersects at the spherical link center PA (PB).

Abstract

La présente invention porte sur une machine de travail destinée à effectuer un travail sur une pièce à travailler (2) au moyen d'un effecteur terminal (1) monté sur un mécanisme rotatif à deux degrés de liberté (3). La pièce à travailler (2) est positionnée dans une ou plusieurs directions axiales par rapport à l'effecteur terminal (1) au moyen d'un mécanisme de positionnement linéaire (5), et la position de rotation de la pièce à travailler par rapport à l'effecteur terminal (1) est déterminée par un mécanisme de positionnement rotatif (4). Lorsque l'angle formé par l'axe neutre (KA) du mécanisme rotatif à deux degrés de liberté (3) et l'axe central de rotation (C3) du mécanisme de positionnement rotatif (4) est un angle d'inclinaison (θ1), et la valeur maximale de l'angle de courbure du mécanisme rotatif à deux degrés de liberté (3) est un angle de courbure maximal (θmax), l'inégalité 0<θ1≤θmax est satisfaite.
