Description
Technical field
The present invention is mainly concerned with and impacts the xegregating unit field, refers in particular to a kind of buffer device of guidance type.
Background technique
When having impact in the equipment running process, the main harm that is caused by impact has: relative displacement or acceleration are caused collision, extruding between the equipment; Impact energy is the moment transmission between each parts, causes intense impact and vibration between the parts, thereby makes the device interior member produce plastic deformation, gap, crackle etc.; The stress balance of equipment is destroyed, and causes the equipment operation instability, degradation, and precision reduces, and shorten working life; External environment condition is caused noise pollution, personnel or equipment are caused consequential injury and damage.
In impact isolating, mainly consider two kinds of situations: 1, when the motion feature on the basis of base or mounting base when impacting, reduce being installed in relative displacement or the acceleration that equipment bears on the base; When 2, the power that acts on (impact block) on the equipment is a sudden surge power, reduces impact force and be delivered to base, the protection supporting structure.
At present, buffer commonly used comprises spring, rubber type (rubber, metal-rubber) and hydraulic type various ways such as (oil pressure, electric/magnetic rheologicals), and pluses and minuses are separately all arranged.Bumper and rubber type buffer store and consume the recoil energy by the resiliently deformable and the friction acting of its generation, but single employing bumper can not store and consume impact energy to greatest extent, and the damping of shocks resistance increases with the increase of cushion stroke, spring or rubber are all return unit, the impact energy major part that buffer receives is converted to elastic energy and is stored in composition recovery energy in the medium, " bounce-back " phenomenon is serious, and damping coefficient is very little.With hydraulic oil is the hydraulic bjuffer of buffer medium, and its buffering efficient is much larger than the buffering efficient of other two kinds of buffers.
Hydraulic draft gear buffering resistance in the buffering overall process is constant substantially, has guaranteed evenly to be slowed down by rammer, and up to stopping, the damping of shocks resistance is also very little, and knockout process does not have bounce-back substantially.The impact energy major part that hydraulic bjuffer is accepted converts heat energy to by the liquid resistance effect in throttling pore or slit, give cylinder body with thermal energy transfer again, be dispersed in the external environment condition and go, only some impact energy becomes elastic energy and is stored in the return unit, so its damping coefficient is very big.But, when the frequency of impact height, when impact acceleration is big, adopt hydraulic bjuffer to have following shortcoming: 1, damping of shocks needs special linear motion guide rail pair, but high-precision linear guide pairs manufacture cost height, size is big, quality is heavy, and lubricated and sealing etc. is difficult in maintenance under the abominable shock environment of complexity; 2, hydraulic buffer need satisfy single, per minute and per hour absorb energy capacity, often needs to increase accumulator, and installing space is restricted, the volume heaviness.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical problem that prior art exists, the invention provides a kind of simple and compact for structure, easy and simple to handle, using effect is good, level of integration is high, applied widely cross double-S type fully compliant mechanism guidance type damping device.
For solving the problems of the technologies described above, the present invention by the following technical solutions.
A kind of cross double-S type fully compliant mechanism guidance type damping device, it is characterized in that: comprise impact block, submissive damping mechanism and buffering connecting base, described submissive damping mechanism comprises buffer-oriented bar, two groups of above plate buffering springs and cushions framework, described buffer-oriented bar is installed in the middle part of buffering framework, described plate buffering spring be symmetry shape be arranged in buffer-oriented bar moving direction both sides and with buffer-oriented bar contact matching, described impact block by the buffering connecting base be installed on the buffer-oriented bar; Sheet spring in described every group of plate buffering spring is the cross double-S type and arranges.
As a further improvement on the present invention:
The width dimensions b in described spring cross section is greater than thickness size h.
Along buffer-oriented bar moving direction, be provided with the adjustable variable coefficient of damping constant between the tail end of described buffer-oriented bar and the buffering framework and concentrate damper.
Described submissive damping mechanism is fixed on the base.
Compared with prior art, advantage of the present invention just is:
1, cross double-S type fully compliant mechanism guidance type damping device of the present invention, be the relief means of integrated form, simple and compact for structure, easy and simple to handle, using effect is good, the resiliently deformable of submissive damping mechanism temporarily stores impact energy, prolong working time of collision, thereby reduce impact force; The effect of damper is that the part with impact energy changes into heat energy and looses and consume, and submissive damping mechanism and variable coefficient are concentrated the damper combination, can be applicable to the buffering requirements of different impact occasions.
2, cross double-S type fully compliant mechanism guidance type damping device of the present invention can reach the purpose of damping of shocks.Submissive damping mechanism utilizes resiliently deformable transmission power and energy between adjacent rigid of material, thereby produces relative translation; The resiliently deformable of submissive damping mechanism temporarily stores impact energy, prolongs working time of collision, thereby reduces impact force; This fully compliant mechanism, form by 4 groups of thickening degree sheet springs, every group of sheet spring adopts cross double-S type structure, and cross double-S type compliant mechanism is arranged symmetrically in the both sides of axis of movement that impact block withstands shocks, and has accurate guide function, substitute the linear motion guide rail pair, alleviate the weight of damping device, reduce the volume of damping device, do not have friction, exempt to lubricate, be easy to safeguard; The effect of damper is that the part with impact energy changes into heat energy and looses and consume, and complete submissive damping mechanism and variable coefficient are concentrated the damper combination, can be applicable to the buffering requirements of different impact occasions; Cross double-S type fully compliant mechanism guidance type damping device has along the impact block axial direction and moves function with damping of shocks, other equipment of effectively protecting base and being connected with base.
