Description
Technical field
The utility model relates to a kind of tensioning frame of adaptive different length steel disc.
Background technology
In the SMT template Laser cutting, the tensioning frame is as the carrier of steel disc, and its effect influences the crudy of steel disc to a great extent.The operation principle of tensioning frame is that the two ends with steel disc are pressed on two beams, and fixing beam with the opposite direction pulling of another beam to steel disc, is evened up steel disc with pulling force.Under the effect of pulling force, sagging, the ripple of steel disc etc. is reduced to a certain degree, and the flatness on steel disc surface reaches certain limit, just can satisfy user demand.Tensioning frame as shown in Figure 1, old, mid portion are the steel disc loading area.Tension mechanism is directly to drive walking beam through screw rod to apply pulling force to steel disc.
The tensioning frame in use because the length specification of steel disc is different, the tensioning frame need make a change according to the steel disc of different size, otherwise can't load steel disc, also just it doesn't matter produces.The method that addresses this problem has 3 kinds: the adaptability that 1) increases frame just extends to the scope of activities of walking beam; 2) under the fixing prerequisite of walking beam stroke with built-in beam as semi-movable, can be according to steel disc length adjustment and locking; 3) or to the steel disc of different size make the tensioning frame of corresponding specification, when the steel disc length specification is changed frame and use.
Clearly, the 3rd kind of method bring the most significantly influence be that production cost significantly rises, need every kind of steel disc specification of every equipment to be equipped with 1 frame, this also is that the client takes notice of the scheme accepted of also being unwilling most.The operation easier that causes increases and stroke increases the risk on the stability of bringing and the stroke that scheme 1 the most direct shortcoming is a walking beam increases.The benchmark that 3 of employing schemes make steel disc stretch easily changes, and changes each time after the suitable specification of tensioning frame, and the installation site of walking beam all is different, and the risk of bringing is also unexpected.
For head it off, the utility model proposes a kind of tensioning frame of easy relatively adaptive different length steel disc.
Summary of the invention
The utility model technical problem to be solved is that the tensioning frame that causes because of cutting steel disc length specification difference in the prior art is suitable for the loaded down with trivial details problem of switching between the specification.The utility model provides a kind of tensioning frame of adaptive different length steel disc newly, and this tensioning frame is easy to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following: a kind of tensioning frame of adaptive different length steel disc comprises housing, built-in beam, walking beam, constant load spring, built-in beam gathering sill, built-in beam detent mechanism, drive screw; The constant load both ends of the spring is connected on built-in beam and the housing, has scale on the housing, with the built-in beam detent mechanism to corresponding, the built-in beam detent mechanism is between built-in beam and constant load spring; Drive screw is positioned on the housing, is connected with walking beam.
In the technique scheme, the built-in beam of constant load spring tension tensioning frame.Built-in beam is positioned at guide securement beam gathering sill.The constant load spring comprises main body and subplate.
In the utility model, use the constant load spring to be used for straining the built-in beam of tensioning frame, in fact the meaning of walking beam and built-in beam existence itself is changed.The structure of walking beam does not need big change, only needs to increase a standard, does the location for the steel disc tensioning state, and is consistent as far as possible with the position of walking beam after the assurance tension.Built-in beam needs an original relatively longer gathering sill, and the constant load both ends of the spring is connected on built-in beam and the housing, and walking beam is drawn towards the opposite direction of walking beam motion.Increase a detent mechanism at the back at built-in beam, preventing on housing, increasing scale there not being built-in beam under the situation of steel disc to be reduced to the position of housing, with detent mechanism to corresponding, so that be fixed to suitable position at the good general's built-in beam that loads steel disc.
When using,, detent mechanism is moved to suitable position locking according to the length specification of each steel disc.This position does not need too accurate, can make things convenient for steel disc to install, and does not have tangible parallelogram variation to get final product; Load steel disc according to normal mode, and move walking beam the position of normal use to.During this time, because of the influence of constant load spring, steel disc can be guaranteed close each time tension effects by a specified pulling force tension; All identical because of the load of each root spring simultaneously, slight angular deflection, the influence of the parallelogram of steel disc all can be contained, and can make the steel disc flatness reach a level preferably.
Only need the detent mechanism of built-in beam be done a slight adjustment according to steel disc length when the steel disc length specification changes gets final product.Change such as steel plate thickness, width causes the tensile force of needs different, also can simply perhaps change the spring specification through the increase and decrease number of springs and realize.Because of spring itself has the characteristics of tolerance, with the uncertain influence reduction that brings of benchmark, as long as in the stroke of spring permission, various steel discs can compatiblely use, and convenient the switching.
During the steel disc tensioning, rotation drive screw pulling walking beam.Steel disc is evened up with continued rotation drive screw up to walking beam being moved to both allocations.Because of the effect of constant load spring, built-in beam moves with walking beam, keeps the tension effects of steel disc itself constant, confirms that up to the position of walking beam the position of built-in beam is also and then decided.When the steel disc length specification changes, change position that steel disc loads to be the steel disc that can supply different size through the position that changes the built-in beam detent mechanism, drawing effect is close.
This programme improves based on the scheme that proposes in the background technology 3, adopts the constant load spring as the fixing transitional link of tensioning frame built-in beam.The maximum characteristics of constant load spring are: after arriving maximum load, in any case prolong stroke, load is constant.Scheme 3 maximum shortcomings are the uncertainty of steel disc tensioning benchmark, and this uncertain influence that brings.The principle that benchmark is decided is very simple, all make the precise positioning benchmark according to every kind of steel disc specification, but really implement more loaded down with trivial details; And in original mechanism, can't eliminate the uncertain influence that brings of benchmark.
The utility model has solved the tensioning frame that causes because of cutting steel disc length specification difference and has been suitable for the loaded down with trivial details problem of switching between the specification, has advantage easy to use, is used for the tensioning of steel disc, has obtained better technical effect.
