Background technology
The driving medium of air-actuated jaw is clean compressed air, and green degree is quite high.However, the cause of Pneumatic Transmission
Life shortcoming be system pressure can not possibly too high (general P=0.4~0.7MPa), thus it is excessive to often result in cylinder bore.Solve this
The effective way of one problem first, after using mechanical force amplifier, the power output of cylinder is amplified, is remake for workpiece；Second is that
Pneumatic Transmission and the force-increasing mechanisms such as inclined wedge, cam, toggle with auto-lock function are combined, in process
Stop supply compressed air, realize energy saving.But the force-increasing mechanism with auto-lock function, required release active force are notable
More than the active force applied when clamping, this undoubtedly adds the difficulty of matching to gas pressure.In the past, Pneumatic Transmission increased with self-locking
The combination application of force mechanisms is very few, and reason lies also in this.In order to improve the greenization of fixture level, we have proposed utilize gas
Impact force caused by the cylinder piston accelerated motion, to unclamp the conception of the self-lockings force-increasing mechanism such as inclined wedge, cam, toggle, and is designed
Impact type air-actuated jaw based on toggle reinforced self-locking mechanism.The fixture operation is simple, and parts are few, and upkeep cost is low, energy
Enough requirements for preferably meeting Green fixture have great meaning for improving China's manufacturing industry industry energy conservation and environmental protection degree
Justice.

Specific embodiment
Impact type air-actuated jaw based on toggle reinforced self-locking mechanism in Fig. 1, mainly by intermediate bar, lever, pneumatic commutation
The compositions such as valve, cylinder, piston, limiting device, toggle；The intermediate bar passes through hinges and two-way toggle mechanism phase group
It closes；The bulb of described activation lever one end, inserted with larger gap in the axial elongated slot of people's piston (bulb diameter be much smaller than axis
To the axial length of elongated slot), the other end of activation lever is fixed hinge；The spool transposition of the air operated reversing valve, makes pressure
Contracting air is right into popularity cylinder（It is left）Chamber；A piston without bar is placed in the cylinder；It is machined in the middle part of the piston
One passes through the axial elongated slot of piston centre；The limiting device ensures to be in self-locking state, Bu Huifa in the position system
Life loosens；The elastic reaction that the two-way toggle flexible deformation generates is applied on workpiece, is realized and is clamped.
The working method of the impact type air-actuated jaw based on toggle reinforced self-locking mechanism is：During initial position, thick stick is driven
Bar top bulb is located at the right side of elongated slot；When piston is under the action of cylinder left chamber compressed air, moved right with certain acceleration
After a distance, axial groove left wall is just in contact with activation lever top ball head, and applies an impact force to bulb；Herein
Under the action of impact force, activation lever is with O1For axle center, make to swing clockwise, so as to drive intermediate bar and two-way toggle machine
Structure acts to the right；After the secondary amplification of one toggle of activation lever, work is outwards exported by power output for axial force suffered by piston
Firmly FO, it is applied on workpiece；In order to realize the reliable grip of greenization and workpiece, two-way toggle mechanism normal quilt during clamp
Shift the position more than dead point onto；At this point, being applied to using the elastic reaction that two-way toggle flexible deformation generates on workpiece, folder is realized
Tightly；Ensure to be in self-locking state in the position system using a limiting device simultaneously, will not get loose；It hereafter can be right
Workpiece carries out machining, can stop supplying to cylinder in process, energy saving to realize；After machining, pneumatically change
It replaces to valve, makes compressed air into popularity cylinder right chamber；Piston after left movement a distance, passes through axis equally with certain acceleration
Apply an impact force to activation lever bulb to slot right wall, so as to fulfill under smaller system pressure lever is promoted to make the inverse time
Pin direction is swung, and toggle is driven to surmount dead point as counter motion, and drive output moves upwards, and is completed to reset, is unclamped workpiece.
It is understood that above with respect to the specific descriptions of the present invention, it is merely to illustrate the present invention and is not limited to this
The described technical solution of inventive embodiments, it will be understood by those of ordinary skill in the art that, still the present invention can be carried out
Modification or equivalent substitution, to reach identical technique effect；As long as meeting using needs, all protection scope of the present invention it
It is interior.
