The specific embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As Fig. 2, comprise clamping bar 1, the first locking nut 2, the second locking nut 3, pad 4, the first ball rings 5, the first sphere pressing plate 6, the first clamping plate 7, the first butterfly springs 8, bearing 9, the second clamping plate 10, the second butterfly springs 11, the second sphere pressing plate 12, the second ball rings 13, cylinder body 14, oil cylinder 15, end cap 16, first piston 17 and the second piston 18.
The utility model is connected to an oil cylinder integral body with cylinder body 14, oil cylinder 15, end cap 16 use screws; The second piston 18 is divided into first, second two cavity A, B with its oil cylinder whole interior space, places first piston 17 in the first cavity; The right-hand member of clamping bar 1 and the second piston 18 are threaded connection; Turn left from the right side and place successively the second ball ring 13, the second sphere pressing plate 12, bearing 9, the first sphere pressing plate 6, the first ball ring 5, pad the 4, second locking nut 3, the first locking nut 2 in cylinder body 14 left sides; Wherein place respectively the second butterfly spring 11 and the first butterfly spring 8 between bearing 9 and the second sphere pressing plate 12 and the first sphere pressing plate 6; The first locking nut 2 be connected locking nut 3 and be connected with clamping bar 1 by screw thread, and form the compression pretensions by screw thread force compresses the first butterfly spring 8 and the second butterfly spring 11, and the first clamping plate 7 and the second clamping plate 10 be in unclamp the operating position; The first clamping plate 7 and the first sphere pressing plate 6, the second clamping plate 10 and the second sphere pressing plate 12 are connected by screw respectively; Bearing 9 is fixed by screws on lathe base.Be provided with the first oil circuit interface and the second oil circuit interface on described end cap 16.
When the needs of clamping cylinder are completed the clamping action: the first oil circuit interface I end oil-feed, the second oil circuit interface II end draining, A chamber oil-feed, promotion first piston 17, piston 18 move right, and promotion oil cylinder integral body is to left movement.The second piston 18 move right drive clamping bar 1 with and on the first locking nut 2, the second locking nut 3 move right.Second locking nut 3 drive pad the 4, first ball rings 5, the first sphere pressing plate 6, the first clamping plate 7 move right; And oil cylinder integral body is moved drive the second ball ring 13, the second sphere pressing plate 12, the second clamping plates 10 left to left movement.So just completed and clamped action.
Complete when the needs of clamping cylinder and unclamp when action: the second oil circuit interface II end oil-feed, the first oil circuit interface I end draining, B chamber oil-feed promotes the second piston 18 simultaneously to left movement, and oil cylinder integral body moves right.The second piston 18 moves left and drives clamping bar 1 to left movement, and the second locking nut 3 and the first locking nut 2 are to left movement.This moment, the first butterfly spring 8 and the second butterfly spring 11 resetted, and promotion the second sphere pressing plate 12, the second ball ring 13, the first sphere pressing plate 6, the first ball ring 5, pad 4 are got back to initial position.So just completed and unclamped action.
