Workpiece positioning, clamping and conveying apparatus

摘要

Connector housings (12) are pushed into a succession of nests (26) formed in workholders (17) mounted on an incrementally advanced turntable (15). Subsequent advance of a workhokder from the connector load station causes a cam follower (42) of a spring-biased lever arrangement (37) to react with a cam track (19) to pivot and move locating pins (31 and 32) into holes (13 and 14) formed in the connector housing. Further advance of the turntable (15) causes a cam follower (64) to ride onto a high portion of a cam track (21) to pivot a second lever arrangement (37) to move a spring-biased, pivotally mounted clamping arm (51) into engagement with the precisely positioned connector housing.
