Embodiment
To make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, below
With reference to embodiment, the utility model is expanded on further.
A kind of round metal coupon tensile test apparatus as shown in Figures 1 to 4, including stretching detection special tooling, the work
Dress include for coupon both ends fix Upper cylindrical fixing piece 1 and lower cylindrical fixing piece 2, the Upper cylindrical fixing piece 1 and
The card slot 3 positioned for coupon 10 is equipped with lower cylindrical fixing piece 2, the tensile test apparatus further includes wedge-shaped self-locking dress
Put, the wedge shape self-locking device includes being fixedly connected on the fixing axle 4 on 1 top of Upper cylindrical fixing piece, the fixing axle 4 with it is upper
Portion's 1 central shaft of cylinder fixing piece is conllinear, and the cross section structure of the fixing axle 4 is the strip structure with Symmetrical Circular Arc, described solid
Dead axle 4 lays screw thread in Symmetrical Circular Arc face, and the wedge shape self-locking device further includes limit base 5 and connecting seat 6, the limit base
