Description

The Tension frame of adaptive different length steel disc
Technical field
The present invention relates to the Tension frame of a kind of adaptive different length steel disc.
Background technology
In SMT template Laser cutting, Tension frame is as the carrier of steel disc, and its effect affects the crudy of steel disc to a great extent.The operation principle of Tension frame is to be pressed on two beams at the two ends of steel disc, fixes a beam, is pulled to the opposite direction of steel disc by another beam, evened up by steel disc with pulling force.Under the effect of pulling force, sagging, the ripple etc. of steel disc is reduced to a certain degree, and the flatness on steel disc surface reaches certain limit, it is possible to meet user demand.As it is shown in figure 1, old Tension frame, mid portion is steel disc loading area.Tension mechanism is directly to be driven walking beam to apply pulling force to steel disc by screw rod.
In use, owing to the length specification of steel disc is different, Tension frame needs the steel disc according to different size to make a change to Tension frame, otherwise cannot load steel disc, and also just it doesn't matter produces.The method solving this problem has 3 kinds: 1) increase frame adaptability namely the range of activity of walking beam is lengthened;2) under the fixing premise of walking beam stroke using fixing beam as semi-movable, it is possible to according to steel disc length adjustment and lock;3) Tension frame of the steel disc making dimension or for different size, changes frame and uses time steel disc length specification is changed.
It is obvious that the most significantly impact the most directly perceived that the 3rd kind of method is brought is that production cost is substantially increased, it is necessary to every kind of steel disc specification of every equipment is equipped with 1 frame, this is also that client takes notice of the scheme being also unwilling to accept most.And the stroke that the most direct shortcoming of scheme 1 is walking beam increases the risk in the stability that the operation easier caused increases and stroke increase brings.Employing scheme 3 then easily makes the benchmark that steel disc stretches change, and after changing the applicable specification of Tension frame each time, the installation site of walking beam is all different, and the risk brought is also unexpected.
In order to solve this problem, the present invention proposes the Tension frame of a kind of relatively easy adaptive different length steel disc.
Summary of the invention
The technical problem to be solved is that the Tension frame caused because of cutting of steel leaf length specification difference in prior art is suitable between specification and switches loaded down with trivial details problem.The present invention provides the Tension frame of a kind of new adaptive different length steel disc, and this Tension frame is easy to use.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows: the Tension frame of a kind of adaptive different length steel disc, including housing, fixing beam, walking beam, constant load spring, fixing beam gathering sill, fixing beam detent mechanism, drives screw rod;Constant load both ends of the spring is connected on fixing beam and housing, and housing has scale, corresponding with fixing beam detent mechanism, and fixing beam detent mechanism is between fixing beam and constant load spring;Drive screw rod to be positioned on housing, and walking beam connects.
In technique scheme, the fixing beam of constant load spring straining Tension frame.Fixing beam is positioned at fixing beam gathering sill.Constant load spring includes main body and subplate.
In the present invention, use constant load spring to be used for straining the fixing beam of Tension frame, actually the meaning that walking beam and fixing beam itself exist is exchanged.The structure of walking beam does not need big change, it is only necessary to increases a standard, positions to steel disc tensioning state, as far as possible consistent with the position of walking beam after ensureing tension.Fixing beam needs a relatively originally longer gathering sill, and constant load both ends of the spring is connected on fixing beam and housing, the opposite direction that walking beam moves towards walking beam is drawn.After fixing beam, increase a detent mechanism, be reduced to the position of housing to prevent from fixing beam when there is no steel disc, housing increases scale, with detent mechanism to corresponding, in order to be fixed to suitable position at the fixing beam of the good general loading steel disc.
When using, the length specification according to each steel disc, detent mechanism is moved to suitable position locking.This position need not be too accurate, it is possible to facilitates steel disc to install, and does not have obvious parallelogram to change;Load steel disc according to normal mode, and walking beam is moved to the position of normal use.Period, because of the impact of constant load spring, steel disc is strained by a specified pulling force, it is possible to ensure tension effects close each time;Simultaneously because the load of each spring is all identical, slight angle offsets, the impact of the parallelogram of steel disc all can be inclusive, it is possible to make steel disc flatness reach a good level.
Have only to, according to steel disc length, the detent mechanism of fixing beam is done a slight adjustment during change of steel disc length specification.It is different that steel plate thickness, width etc. change the tensile force causing needs, it is also possible to realizes simply by increase and decrease number of springs or replacing spring specification.Because spring is per se with the feature of tolerance, uncertain for the benchmark impact brought being weakened, as long as in the stroke of spring license, various steel discs can compatible use, and convenient switching.
During steel disc tensioning, drive screw pulls walking beam.Steel disc continues drive screw until moving walking beam to commitment positions after evening up.Because of the effect of constant load spring, fixing beam moves with walking beam, and the tension effects keeping steel disc itself is constant, until the position of walking beam is determined, the position of fixing beam is also and then decided.Steel disc length specification change time, by change fixing beam detent mechanism position change steel disc load position be able to supply different size steel disc, drawing effect is close.
This programme improves based on the scheme 3 proposed in background technology, adopts the transitional link that constant load spring is fixed as the fixing beam of Tension frame.The maximum feature of constant load spring is: after arriving maximum load, in any case extend stroke, load is constant.The maximum shortcoming of scheme 3 is in that the uncertainty of steel disc tensioning benchmark and this uncertain impact brought.The principle to be decided by benchmark is very simple, all makes the positioning datum of precision according to every kind of steel disc specification, but really implements comparatively laborious;And the uncertain impact brought of benchmark cannot be eliminated in original mechanism.
The invention solves the Tension frame caused because of cutting of steel leaf length specification difference to be suitable between specification and switch loaded down with trivial details problem, there is advantage easy to use, for, in the tensioning of steel disc, achieving good technique effect.

Specific embodiment
[embodiment 1]
The Tension frame of a kind of adaptive different length steel disc, as shown in Figure 2,3, including housing, fixing beam, walking beam, constant load spring, fixing beam gathering sill, fixing beam detent mechanism, drives screw rod;Constant load both ends of the spring is connected on fixing beam and housing, and housing has scale, corresponding with fixing beam detent mechanism, and fixing beam detent mechanism is between fixing beam and constant load spring;Drive screw rod to be positioned on housing, and walking beam connects.
[embodiment 2]
The Tension frame of a kind of adaptive different length steel disc, including housing, fixing beam, walking beam, constant load spring, fixing beam gathering sill, fixing beam detent mechanism, drives screw rod;Constant load both ends of the spring is connected on fixing beam and housing, and housing has scale, corresponding with fixing beam detent mechanism, and fixing beam detent mechanism is between fixing beam and constant load spring;Drive screw rod to be positioned on housing, and walking beam connects.
In such scheme, use constant load spring to be used for straining the fixing beam of Tension frame, actually the meaning that walking beam and fixing beam itself exist is exchanged.The structure of walking beam does not need big change, it is only necessary to increases a standard, positions to steel disc tensioning state, as far as possible consistent with the position of walking beam after ensureing tension.Fixing beam needs a relatively originally longer gathering sill (this is not problem when using section bar as housing), and constant load both ends of the spring is connected on fixing beam and housing, the opposite direction that walking beam moves towards walking beam is drawn.After fixing beam, increase a detent mechanism, be reduced to the position of housing to prevent from fixing beam when there is no steel disc, housing increases scale, corresponding with detent mechanism, in order to before loading steel disc, fixing beam to be fixed to suitable position.
Constant load spring, roller and subplate that time fixing, main body is middle are separately fixed at two effect ends.Connect fixing beam by constant load spring, increase the detent mechanism of fixing beam.As shown in Figure 2.
When using, the length specification according to each steel disc, detent mechanism is moved to suitable position locking.This position need not be too accurate, it is possible to facilitates steel disc to install, and does not have obvious parallelogram to change;Load steel disc according to normal mode, and walking beam is moved to the position of normal use.Period, because of the impact of constant load spring, steel disc is strained by a specified pulling force, it is possible to ensure tension effects close each time;Simultaneously because the load of each spring is all identical, slight angle offsets, the impact of the parallelogram of steel disc all can be inclusive, it is possible to make steel disc flatness reach a good level.As shown in Figure 4 and Figure 5.
Have only to, according to steel disc length, the detent mechanism of fixing beam is done a slight adjustment during change of steel disc length specification.It is different that steel plate thickness, width etc. change the tensile force causing needs, it is also possible to realizes simply by increase and decrease number of springs or replacing spring specification.Because spring is per se with the feature of tolerance, uncertain for the benchmark impact brought being weakened, as long as in the stroke of spring license, various steel discs can compatible use, and convenient switching.
New tensioning mechanism.During steel disc tensioning, drive screw pulls walking beam.Steel disc continues drive screw until moving walking beam to commitment positions after evening up.Because of the effect of constant load spring, fixing beam moves with walking beam, and the tension effects keeping steel disc itself is constant, until the position of walking beam is determined, the position of fixing beam is also and then decided.Steel disc length specification change time, by change fixing beam detent mechanism position change steel disc load position be able to supply different size steel disc, drawing effect is close.
