Abstract
The present invention discloses a dual cantilever adhesion sample thickness controller, which comprises a base, a guide rod, a moving block, a handle, a lower support block and an upper support block, wherein the base is fixed on one end of the guide rod, the other end penetrates through the moving block, the moving block is provided with the handle for driving the moving block to move along the guide rod, the upper end surface of the moving block is provided with the low support block, and the position on the base lower end surface and corresponding to the lower support block is provided with the upper support block. According to the present invention, the gear rack is used to drive the moving block to move up and down and has the fixed transmission ratio, such that the moving distance of the moving block can be accurately controlled so as to accurately control the adhesive thickness; and the two or more than two separate support blocks are used to form the controller, such that the self-weight can be reduced, the multi-point pre-tightening can be achieved along the sample length direction, and the thickness uniformity of the adhesive in the whole adhesion region can be controlled.
Description
Technical field
The invention belongs to Experiments of Machanics sample production technical field, particularly a kind of two cantilever bonding sample gage controller.
Background technology
In the sample of numerous test bonding interface energy to failure, double cantilever beam testing both can use beam theory to carry out simplify processes data, stable crack propagation can be guaranteed again, thus false effect when avoiding energy to failure to measure, therefore, double cantilever beam testing is particularly suitable for the flexible component test that flexible material combines.Show according to research, adhesive thickness has a great impact the fracture behaviour tool that the adhesive property at interface and interface represent in failure procedure.But in the manufacturing process of sample, the thickness of adhesive layer (or claiming contact bed) is difficult to control, want to reach good experiment effect and then will ensure that the thickness of adhesive can obtain controlling comparatively accurately, and thickness is uniform in whole bonding region.
For adhesive thickness control problem in double cantilever beam bonding sample, propose in document Rate-dependent crack growth inadhesives II.Experiments and analysis to adopt the method inserting steel shim in one end, interface.This method is that metal material that rigidity is larger or compound substance are comparatively applicable to semi-girder beam arm.And for the flexible component that picture flexible material combines, beam arm can occur in local larger distortion or or displacement, the method for shimming can not control adhesive thickness at all bonding regions.Another kind method is in adhesive, add some small spheric grain, is determined the thickness of adhesive by the diameter of particle.When particle in bonding region be substantially be uniformly distributed time, the method is comparatively effective, but the particle added can affect the original adhesive property at interface, and the interphase fracture energy measured can be caused to depart from actual value.
Summary of the invention
The object of the present invention is to provide a kind of two cantilever bonding sample gage controllers that can be used in the flexible component test that flexible material combines.
The technical solution realizing the object of the invention is:
A kind of two cantilever bonding sample gage controller, comprise pedestal, guide rod, movable block, handle, lower support block, upper back-up block, guide rod is fixed with pedestal, the other end is through movable block, movable block is provided with the handle driving movable block along guide rod movement, the upper surface of movable block is provided with lower support block, and the position that up and down, the lower surface back-up block of pedestal is corresponding is provided with back-up block.
The present invention compared with prior art, its remarkable advantage:
(1) the present invention drives the mode that moves up and down of movable block owing to adopting rack-and-pinion, and rack-and-pinion has fixing ratio of gear, therefore, it is possible to the accurate distance controlling movable block movement, reaches the function accurately controlling adhesive thickness.
(2) the present invention is due to the back-up block composition adopting two or more independent, can either alleviate deadweight, can realize multiple spot pretension again, can control the consistance of adhesive thickness in whole bonding region along the length direction of sample.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
