Specific embodiment
Present invention is further described in detail with reference to embodiments.
The utility model proposes a kind of pressure test machines, and as shown in Fig. 1 to 5, which includes pedestal 1,
Pedestal 1 is equipped with tension-compression sensor 2 and column 4, and the upper end of column 4 is fixed with upper beam 5, on upper beam 5 and tension-compression sensor 2
It is equipped with jaw device 3, jaw device 3 is oppositely arranged at two；Cavity 7 and cylinder 6 are equipped in jaw device 3, cylinder 6 is located at sky
7 bottom of chamber, the two sides of cavity 7 slope inwardly and are equipped with the snap-gauge 8 that can be slided along inclined surface, are connected with clamping plate on two pieces of snap-gauges 8
9, groove 11 is provided with close to 6 one end of cylinder on the opposite face of two sides snap-gauge 8, and jaw device 3 further includes pressing plate 1 and pressing plate two
13, pressing plate 1 is caught in grooves on two sides 11 and connect with cylinder 6, the both ends of pressing plate 1 and the opposite side of grooves on two sides 11
There are gap between wall, connecting rod 14 is accompanied between two clamping plates 9, jaw device 3 is stretched out in one end of connecting rod 14 and pressing plate 2 13 connects
It connects；Be further fixed on hydraulic lift 15 on upper beam 5, hydraulic lift 15 be fixed on the top of upper beam 5 and with upper cross
Jaw device 3 on beam 5 connects, and by the operating of hydraulic lift 15, the jaw device 3 on upper beam 5 can be the bottom of relative to
Seat 1 moves up and down.Cylinder 6 is increased in jaw device 3, when cylinder 6 operates, can be moved with dynamic pressure plate 1, pressing plate
One 12 drive two sides snap-gauge 8 mobile, since 7 two sides of cavity slope inwardly, so will drive two sides clamping plate 9 when snap-gauge 8 moves
It is inwardly close, so that the spacing between two clamping plates 9 reduces, thus make to be clipped in the bigger chucking power of test block acquisition therein,
And between pressing plate 1 and snap-gauge 8 there are sliding of the gap also for snap-gauge 8 provide space.
The utility model is equipped with graphene layer (not shown) between snap-gauge 8 and the side wall of cavity 7, so that snap-gauge 8
