Abstract
An automatic unit for distributing and installing rings, particularly composite rings, on engine pistons, and which includes a first device for separating elastic expanders (b 1a) consisting of two pairs of helical ramps (26, 27) and (28, 29) having opposite winding directions driven simultaneously by a ring gear (30), and of an escapement mechanism (32) controlled by a cylinder (34) able to cause the turn portion corresponding to one helical ramp turn to be performed on this ring.
Claims6
An automatic unit for distributing and installing rings, on internal combustion engine pistons, of the type integrated into a robotized assembly line, and provided with automatic means for gripping the pistons, for detecting the type of pistons taken, for intitializing and for identifying the height of the grooves of the pistons on ogives for stacking of rings, for selecting and for presenting the ogives, which comprises:
- means for separating elastic expanders which includes two pair of helical ramps and having opposite winding directions, and
- an escapement mechanism controlled for causing a turn corresponding to one helical ramp turn to be performed on this ring.
