FIELD: machine engineering. SUBSTANCE: quick-release aggregate includes clamped and clamping ground-mounted mechanisms. The last are provided with pushers having through control ducts and they are sealed one relative to another by means of sealing member. There is groove in cup. Depth of said groove is equal to thickness of stop of clamped mechanism. There are throttling openings in pneumatic drive unit of clamped mechanism. Said throttling openings are communicated with cavity of locking sleeve in order to delay operation of locking sleeve. EFFECT: enhanced reliability of operation and disconnection of collet chuck, lowered mass of board part of spatial vessel. 2 dwg |
