The specific embodiment

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

As shown in Fig. 1 to Fig. 3 A, a kind of clamp mechanism 100 that the utility model relates to, comprise mandrel crowfoot 1, mobile protruding dish 2 and a plurality of calvus 3 that arrange in the form of a ring, this moves protruding dish 2 and is set on mandrel crowfoot 1, and this moves protruding dish 2 and can move up and down along mandrel crowfoot 1 axis direction.As this, move a kind of concrete type of drive of protruding dish 2 and mandrel crowfoot 1, this clamp mechanism 100 also comprises cylinder body 4 and is positioned at cylinder body 4 and is the fixedly piston 5 of shape, this cylinder body 4 can move up and down along piston 5, this moves protruding dish 2 and is fixedly linked with cylinder body 4, this mandrel crowfoot 1 runs through this piston 5 and is fixedly linked with piston 5, specifically by binding nut 51, be connected, this type of drive that moves protruding dish 2 can also be substituted by alternate manner certainly, as long as can produce, moves up and down.

This moves protruding dish 2 has accommodating cavity 21 and is formed on the holding part 22 on cavity inner wall 211, on this mandrel crowfoot 1, be formed with the annular deep gouge 11 that is arranged in accommodating cavity 21, the plurality of calvus 3 all has and is positioned at the inner end of accommodating cavity 21 and is positioned at the outer end outside accommodating cavity 21, each calvus 3 all has spheric seat 31, the first stopper 32 and the second stopper 33, this first stopper 32 and the second stopper 33 are separately positioned on the inside and outside both sides of spheric seat 31, the spheric seat 31 of each calvus 3 all rotates and is arranged in annular deep gouge 11, this holding part 22 is conflicted in calvus 3 outside wall surface 34 movable between the first stopper 32 and the second stopper 33.

Like this, in the utility model, each calvus 3 is all rotated and is arranged in annular deep gouge 11 by the spheric seat 31 on it, makes a plurality of calvus 3 arrange ringwise; If Fig. 3 to Fig. 2 is to as shown in Fig. 1, when mobile protruding dish 2 moves down, this holding part 22 can leave the first stopper 32 and little by little act on mutually with the second stopper 33, and now each calvus 3 all be take spheric seat 31 as center of rotation, thereby clamps action; If Fig. 1 to Fig. 2 is to as shown in Fig. 3, when mobile protruding dish 2 moves up, this holding part 22 can leave the second stopper 33 and little by little act on mutually with the first stopper 32, and the spheric seat 31 of now take unclamps action as center of rotation.It should be noted that, each calvus 3 has two side wall surfaces 35, when mobile protruding dish 2 moves down, the distance between adjacent calvus 3 side wall surfaces 35 is shortened, and then utilizes the clamping force between adjacent calvus 3 side wall surfaces 35 to clamp discrete components, when mobile protruding dish 2 moves upward, distance between two side wall surfaces 35 is increased, thereby unclamps discrete components, specifically refers to shown in Figure 1A, Fig. 2 A and Fig. 3 A, wherein d2 is greater than d1, thereby realize, unclamps and the switching that clamps action.
