Mechanical device for locating assembly in three dimensions by means of pilot cavity with retractable hooks operated by piston

摘要

The mechanical device consists of a pilot cavity (1)(X - Y axes) fitted with two retractable hooks (2), (Z axis) which are driven by a piston (3), which slide within the pilot cavity. This piston is fitted with a characteristic groove, which allows the hooks to be driven in rotation, through the effect of two lugs. The piston is driven in translation by a three point mechanism (8), operated by a pneumatic jack (10) or manually.
