Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of mechanical-electrical-hydraulic integration and all press clamping device.
Background technology
No matter be the traditional mechanical manufacturing industry, or the modern mechanical manufacturing industry, the effect of jig all is crucial.And the core of jig then is a clamping device.
In practical project is used, during run into rough workpiece through regular meeting and need implement to clamp, perhaps a plurality of workpiece need to implement simultaneously to clamp, if at this moment just can not meet the demands with traditional flat grip part device.And in the Precision Machining operation,, especially need use multiple spot all to press clamping device in order to reduce the contact stress between clamping element and the workpiece to be clamped surface.
All press clamping device, traditional generally is to utilize the plural serial stage lever to realize that the multiple spot multidigit clamps, but so, employed mechanism is just very lengthy and tedious, and structure is very not compact, and rigidity is also good inadequately.And, generally can be divided into hydraulic pressure, pneumatic and manual three types from the classification of the power resources of clamping device.Multiple spot or multidigit jig generally all need bigger clamping force, and generally, people are often forced must to adopt hydraulic clamp, pollute because of hydraulic oil volatilizees and leaks surrounding enviroment such as causing air, ground but hydraulic drive is as easy as rolling off a log.Pneumatic Transmission also has the distinct disadvantage that himself can't overcome, because the as easy as rolling off a log leakage of gas, causes the operating pressure of pneumatic actuator system can not be very high.In the engineering field, air-driven system pressure is generally at p at present
A=0.4～0.7MP
aScope in, so low system works pressure tends to cause requiring the bigger occasion of power output, the volume of pneumatic cylinder diameter and whole device must let the people accept greatly.And manually all press anchor clamps, can not realize the automation control of clamping force having bigger limitation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, clamp effective and mechanical-electrical-hydraulic integrations energy-conserving and environment-protective are all pressed clamping device.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of mechanical-electrical-hydraulic integration is all pressed clamping device; Comprise drive unit, transmission device, toggle mechanism and clamp mechanism; Said transmission device comprises the shaft coupling that an end is connected with said drive unit output, and the said shaft coupling other end is connected with sliding screw, and said sliding screw is provided with nut;
Said toggle mechanism comprises one-level toggle and the secondary toggle that is symmetricly set in the nut both sides; Said one-level toggle one end and nut are hinged; The other end is hinged with an end of two secondary toggles respectively; One of them secondary toggle other end is with point articulated, and another secondary toggle other end and said clamp mechanism are hinged;
Said clamp mechanism comprises and the hinged slide block of said secondary toggle, offers hydraulic cavities in the said slide block, is filled with hydraulic oil in it, and said slide block is provided with at least two plunger clamping elements, and the inner and said hydraulic cavities of said plunger clamping element is conflicted.

In the technique scheme, be power source with the servomotor, the servomotor clutch end is connected with sliding screw through shaft coupling; With the slip screw transmission rotation of servomotor is converted into the rectilinear motion of nut on sliding screw; Sliding up and down again of nut carried out the power amplification by one-level toggle and secondary toggle, then through slide block output, and the inner hydraulic cavities of slide block for sealing; Be filled with hydraulic oil in it, many plunger clamping elements and this hydraulic cavities are inconsistent.Clamping device is at work the time; When wherein certain plunger clamping element at first touches workpiece, can transfer the pressure on other plunger clamping element through the medium hydraulic oil that floats, promote the plunger clamping element and move downward; And then make other plunger clamping element contact work, realize all pressing clamping work pieces.The floating action of medium hydraulic oil owing to float; Can guarantee that the plunger clamping element evenly applies pressure to workpiece with identical active force, perhaps apply different workpiece, because the viscosity of the medium hydraulic oil that floats is very big with identical active force; So do not need special sealing; Therefore this apparatus structure is simple, in actual use a plurality of plunger clamping elements can be set as required, satisfies the real work situation.In addition, also be connected with pressure switch, dynamically detected pressures and then servomotor controlled with the hydraulic cavities of sealing.
In the technique scheme, clamping device have a very high symmetry, thereby also just have good mechanical technology index, actual total power output F of clamping device
OpComputing formula:
In the formula, α, β are the theoretical pressure angle,
Be the equivalent friction angle of one-level toggle,
Be the equivalent friction angle of secondary toggle, M is the output torque of servomotor, d
2Be the middle footpath of sliding screw, λ be lead screw lift angle (can by
Obtain, wherein L is a helical pitch),
Equivalent friction angle for lead screw.
If have n plunger clamping element, the then F of each plunger clamping element arranged in the clamping device
OpeFor:
The condition of mechanism's self-locking:
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1. servomotor is connected with sliding screw through shaft coupling among the present invention, and sliding screw is provided with nut, is hinged on the nut bilateral symmetry with nut toggle mechanism is set; Toggle mechanism and slide block are hinged, and servomotor is converted into the rectilinear motion of nut on sliding screw, carry out power by the toggle toggle again and amplify; Realize all pressures of workpiece are clamped through the output of the plunger clamping element on the slide block then; Simple in structure, easy to use, and clamp effective;
