Adopt above structure, in clamping limb, depression bar (6) travels forward, clamping limb (2) is driven to close, clamping needs the original paper of Milling Process, machine rear clamping limb (2) to reset under the effect of reseting pressuring spring (5), because the thickness of the large I of clamping limb (2) the folding original paper as required of this structure adjusts flexibly, therefore applied widely, and it is simple to operate, chuck strength is high, reduce the vibration of original paper during Milling Process, effectively improve machining accuracy.
As preferably: the afterbody of two described clamping limbs (2) towards depression bar (6) direction in described clamping limb from reducing gradually outside to inside.Adopt above structure, structure is simple, reliable, reasonable.
As preferably: in described clamping limb, depression bar (6) front end is provided with the inner chamber (6a) matched with the afterbody of described clamping limb (2), and the internal diameter of this inner chamber (6a) increases from inside to outside gradually towards described clamping limb (2) direction.Adopt above structure, structure is simple, reliable, reasonable.
As preferably: the madial wall of described inner chamber (6a) and the lateral wall of described clamping limb (2) afterbody are fitted completely.Adopt above structure, in effective raising clamping limb, depression bar (6) is to the chuck strength of clamping limb (2).
As preferably: described clamping limb (2) and described pilot sleeve (4) integrated molding.Adopt above structure, effectively increase the bonding strength of clamping limb (2) and pilot sleeve (4).
Beneficial effect: the clamping mechanism adopting the band cylinder of above technical scheme, structure is simply novel, is easy to realize, and flexibly, applied widely, chuck strength is high in adjustment, reduces the vibration of original paper during Milling Process, effectively improves machining accuracy.
