Described pedestal inner side is provided with symmetrical location and presses keyway.
Described outer rotary table is combined by two and half arc rotating disks.
The tooth of described inner rotary table and outer rotary table is the unidirectional tooth matching, and combined type rotating disk can only forward rotation, during reversion, can produce self-locking, thereby realize, clamps locking.
The arranged outside of described outer rotary table has annular groove, is provided with and locates the keyway of pressing key to coordinate in groove, is provided with spring in keyway, and the tension force by spring makes location press the automatic and outer rotary table of key to compress.
Described clamping device is flexibly connected and forms with clamping hand by clamping limb, can realize the flexible clamping to irregularly shaped workpiece by axial-rotation.
The contact-making surface of described clamping hand and workpiece is provided with plastic cement pad, and plastic cement easily produces elastic deformation and rigidity is low, when clamping, can produce larger frictional force, plays the effect of stable holding, and does not damage the part that rigidity value is higher than soft plastic.
The inwall of described inner rotary table is provided with projection, and the clamping limb of clamping device is hinged on projection, and projection plays protection pin joint.
The interior ring of described outer rotary table is provided with three raised lines that coordinate clamping limb to play balance pivot effect.
Described combined type rotating disk is provided with the top cover adaptive with it, and top cover is provided with three cylinders that annular is uniform, and cylinder coordinates with clamping limb is hinged; Top cover is also provided with three circular holes that annular is uniform.
Described location is pressed the cambered surface of key and the cambered surface of outer rotary table annular groove to overlap and is contacted, and has strengthened like this contact area of location pressure key and outer rotary table, has increased friction effect, and the way of contact not overlapping of comparing can produce better locking effect.
The working method of this device: first object is placed on to clamping device cavity place, then three the cylindrical handles that have that specifically coordinate with three circular holes of top cover are inserted to circular hole, to handle, apply and be rotated in the forward power, make top cover rotation, make three clamping limbs tighten up to the object centre of form simultaneously, object is clamped.In clamping process, in order to ensure more stable clamping, while adopt, clamp the slightly method fast and stable clamping of left-right rotation object.After clamping, take out handle, clamping mechanism is arranged on to the position that needs installation.When needs draw off object, utilize equally handle to be rotated in the forward, top cover is rotated to the position that location presses key and outer rotary table keyway to overlap, now, owing to there being contact drop, can send slight impact sound, then utilize handle to counter-rotate to clamping device and unclamp object.So far, the whole course of work is complete.
Advantage of the present invention: the utility model clamping device is by adopting combined type rotating disk to be connected synchronous working with clamping device, can rapidly measured workpiece clamping be arrived to stable position, can produce larger chucking power to the larger object of volume, can clamp more firmly object; Object to small volume reduces pressure, can reduce object to cause the impact of deformation; Combined type rotating disk has strengthened locates stressed area, has stablized chucking power, can clamp more firmly object; By adopting the flexible connection of clamping limb and clamping hand, increased the flexibility of clamping hand, clamping object is to stable position better.
