Abstract
The utility model discloses 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 mode that the utility model moves up and down owing to adopting rack-and-pinion to drive movable block, 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; And the utility model 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.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model 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 utility model object 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 utility model compared with prior art, its remarkable advantage:
(1) the utility model 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 utility model 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 utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram of the two cantilever bonding sample gage controller of the utility model.
Embodiment
Composition graphs 1:
A kind of two cantilever bonding sample gage controller of the utility model, comprise pedestal 1, guide rod 2, movable block 3, handle 4, lower support block 5, upper back-up block 6, guide rod 2 one end is fixed with pedestal 1, the other end is through movable block 3, movable block 3 is provided with the handle 4 driving movable block 3 along guide rod 2 movement, the upper surface of movable block 4 is provided with lower support block 5, and the position of up and down, lower surface back-up block 5 correspondence of pedestal 1 is provided with back-up block 6.
Coordinated by gear & rack structure between guide rod 2 with movable block 3, because rack-and-pinion has fixing ratio of gear, therefore, it is possible to the accurate distance controlling movable block movement, reach the function accurately controlling adhesive thickness.
Lower support block 5 and upper back-up block 6 are separately positioned in groove that movable block 3 and pedestal 1 have, and are slidably matched with groove, and lower support block 5 and upper back-up block 6 can move freely respectively in groove.
The back-up block composition that lower support block 5 and upper back-up block 6 adopt 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.
