Abstract
A vacuum holding fixture for a thermoformed part carries a base attachment plate which is releasably coupled to the top wall of a vacuum support box having a vacuum passage sealed to a vacuum passage within the attachment plate and a vacuum chamber within the holding fixture. The attachment plate is precisely positioned and releasably locked to the vacuum box by a plurality of couplers each including a stud projecting downwardly from the attachment plate and received within a corresponding cylinder recessed within the vacuum box. Each cylinder has locking balls which releasably grip the corresponding stud in response to axial movement of a fluid actuated spring biased piston surrounding the cylinder.
