PCT No. PCT/FR89/00031 Sec. 371 Date Oct. 17, 1989 Sec. 102(e) Date Oct. 17, 1989 PCT Filed Jan. 30, 1989 PCT Pub. No. WO89/08012 PCT Pub. Date Sep. 8, 1989.In a multi-axis mechanical manipulator with adjustable travel and protection against overloading. The movement is transmitted to the indexing mechanism (10) by the combination of a sliding rotor motor (2) of a reducing gear with wheel and endless screw (30) and an adjustable torque limiter (40). The law of motion of the indexing mechanism (10) is determined in this way so as to obtain constant speed over a wide range, possibly with stopping points. The rotating frame (56) is linked to the indexing mechanism (10) by a spring bushing (50). The movement is transmitted to the cylindrical cam (6) by an adjustable torque limiter (28). The manipulating arm (7) is displaced by a spring plate which permits a momentary angular retraction of the arm (7) when it encounters an obstacle. The present invention may be used for the handling of loads or parts. |
