Abstract
An adjustable clamping mechanism includes a slider block annularly disposed about a rod device within a mechanical press. The mechanism utilizes a press or interference fit connection between the components. During operation, high-pressure oil is injected into the location between the slider block and rod, thereby relieving the press fit and making it possible to have relative movement therebetween. An actuator causes selective linear displacement of the slider block along the longitudinal axis of the stationary rod during the release condition. Once the slider block is repositioned, the high-pressure oil is removed, which reactivates the press fit connection and causes the slider block to once again lock up against the rod and prevent movement therebetween.
