ROBOTIC WORKING MODULE WITH PARALLEL KINEMATICS

摘要

P The present invention relates to a robotic working module with parallel kinematics comprising a fixed platform, integral with the structure of said module, and a platform movable relative to said structure and integral with a platform tool, the construction of the junction between the two platforms is simplified, more compact and therefore less expensive. The two platforms are connected by six extendable link arms (13) and linked two by two, at one of their ends, by an articulation device secured to the mobile platform. The fixed platform (10) comprises three crosspieces (12) forming a triangle fixed to the structure of said module by means of anchoring studs (11). Each link arm (13) is integral with one of said crosspieces (12) by means of a joining element (14) which pivots in said crosspiece by means of an element (19) defining the axis of rotation of said element (14), and said cross member is pivotable in the platform (1 0). Each anchoring stud (11) has two cylindrical bores (18) which cooperate with a pivot (17) formed on the end faces (16) of two fixed crosspieces (12). /P
