Technical field
The present invention relates to clamping device, specifically a kind of clamping device clamping the measured piece centre of form.
Background technology
In measurement mechanical, often to carry out stable clamping to measured piece, measured piece usually will be made to rotate fixed angle around a fixed axis when needs are measured multiple face, the position of measured piece does not change in the other direction simultaneously, so repeatedly rotates repetitive measurement.Operate steadily when rotating to make measured piece and reliably, the measured piece centre of form determined in clamping device center shaft axis.Like this, when measured piece is clamped, just can find stable holding position sooner, and dismantle convenient.And existing clamping device, this requirement can not be met very well.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and a kind of clamping device clamping the measured piece centre of form is provided.This clamping device can not only meet measurement mechanism to axial-rotation location and the requirement of clamping, and can realize the harmless clamping to measured workpiece, and this clamping device structure is simple simultaneously, and entirety does not have interference fit, thus is convenient to dismantle and maintains.
The technical scheme realizing the object of the invention is:
A kind of clamping device, comprise pedestal, described pedestal is provided with circular cavity, and in circular cavity, coupling is provided with combined type rotating disk; Combined annular rotating disk is meshed is formed by the outer rotary table of the inner rotary table with external tooth and band internal tooth; Also be provided with clamping device, clamping device is connected with inner rotary table; Between pedestal and outer rotary table, coupling is provided with the location pressure key of movable connection.
Symmetrical location pressure keyway is provided with inside described pedestal.
Described outer rotary table is formed by two and half arc disk combination.
The tooth of described inner rotary table and outer rotary table is the unidirectional tooth matched, and combined type rotating disk can only rotate forward, and can produce self-locking during reversion, thus realizes clamping locking.
The arranged outside of described outer rotary table has annular groove, is provided with and locates the keyway of pressing key to coordinate, be provided with spring in keyway in groove, by the tension force of spring make location pressure key automatically and outer rotary table compress.
Described clamping device to be flexibly connected with holding hand by clamping limb and to form, and can realize to irregularly shaped workpiece flexible clamping by axial-rotation.
The contact surface of described holding hand and workpiece is provided with plastic cement pad, and plastic cement easily produces elastic deformation and rigidity is low, can produce larger frictional force, playing the effect of stable holding when clamping, and the part that damage stiffness value is not 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 a part to protect pin joint.
The inner ring of described outer rotary table is provided with three raised lines coordinating clamping limb to play balance pivot effect.
Described combined type rotating disk is provided with the top cover with its adaptation, and top cover is provided with the uniform cylinder of three annulars, and cylinder coordinates with clamping limb is hinged; Top cover is also provided with the uniform circular hole of three annulars.
The described location pressure cambered surface of key can overlap with the cambered surface of outer rotary table annular groove and contact, and increase the contact area of location pressure key and outer rotary table like this, increase friction effect, the way of contact do not overlapped of comparing can produce better locking effect.
The working method of this device: first object is placed on clamping device cavity place, then three the cylindrical handles that have specifically coordinated with top cover three circular holes are inserted circular hole, apply to rotate forward power to handle, top cover is rotated, make three clamping limbs tighten up to the object centre of form simultaneously, object is clamped.In order to ensure more stable clamping in clamping process, adopt the method fast and stable clamping clamping slight left-right rotation object.After clamping, take out handle, clamping mechanism is arranged on the position needing to install.When needs draw off object, utilize handle to rotate forward equally, top cover is rotated to the position of location pressure key and the coincidence of outer rotary table keyway, now owing to there being contact drop, slight impact sound can be sent, then utilize handle reverse rotation to unclamp object to clamping device.So far, the whole course of work is complete.
Advantage of the present invention: clamping device of the present invention is connected synchronous working by adopting combined type rotating disk with clamping device, can rapidly by measured workpiece clamping to stable position, chucking power that can be larger to the object generation that volume is larger, can gripping objects more firmly; Pressure is reduced to the object of small volume, impact object being caused to deformation can be reduced; Combined type rotating disk increases the stressed area in location, stabilizes chucking power, can gripping objects more firmly; By adopting the flexible connection of clamping limb and holding hand, add the flexibility of holding hand, can better clamping object to stable position.
