Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below will With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to Fig. 1-5, present embodiment is achieved using following technical scheme, and it is symmetrical arranged comprising two Original position stretching machine worktable 2, fixed pedestal 15 is installed on the original position stretching machine worktable 2, the fixed pedestal 15 with it is in situ Spun and be integrally fixed by stud between stretching machine worktable 2, the side of top surface is vertically installed with the fixed pedestal 15 Angle scale 1, interfaced bar specimen holder or sheet coupon fixture are installed in described angle scale 1;
The described generally disc-shaped structure of angle scale 1, the middle part insertion of the angle scale 1 offer a fixture rotation hole 14, corresponding angle value is etched with the periphery of the angle scale 1.
Described sheet coupon fixture includes upper fixture 3 and lower clamp symmetrically arranged with upper fixture 34, and upper fixture 3 is with By being integrally fixed with alignment pin 8 and stud between fixture 4, described upper fixture 3 offers with being penetrated respectively on lower clamp 4 Can be with the holder pin hole 7 of the clearance sliding fit of alignment pin 8, the both ends of the alignment pin 8 are respectively arranged with can be with its interference The positioning rubber set 9 that socket coordinates;
The side of the upper fixture 3 extends outward can be with the upper fixture arcuate structure of the clearance sliding fit of fixture rotation hole 14 5;
The side of the lower clamp 4 extends outward can be with the lower clamp arcuate structure of the clearance sliding fit of fixture rotation hole 14 6;
Described upper fixture arcuate structure 5 forms a circular ring after being docked with lower clamp arcuate structure 6.
The bar specimen holder includes baffle plate 13, and one end of the baffle plate 13 axially outwardly extends one can be with fixture The cylindrical positioning table 16 of the clearance sliding fit of rotation hole 14, concentric screwed hole is offered on the cylindrical positioning table 16 12。
The application method of technical scheme part in present embodiment and its principle are made below in conjunction with the accompanying drawings further Elaboration:
When carrying out the stretching of sheet coupon, two holder pin holes 7 of upper fixture 3 and lower clamp 4 are positioned with sheet coupon respectively Hole 10 keeps concentric, is inserted into alignment pin 8, and ensures that upper fixture arcuate structure 5 aligns with lower clamp arcuate structure 6, so Upper fixture 3 and lower clamp 4 and sheet coupon are fastened by stud afterwards, recycle rubber positioning sleeve 9 to be fixed on alignment pin 8 On sheet coupon fixture;
