A tubular joint fatigue test fixture for resisting uniaxial loading

Abstract

The application discloses a kind of technical field for bearing uniaxial load pipe joint fatigue test fixture, including a pair of limiting frame, the top and bottom of both ends of two described limiting frame are fixedly connected with connecting plate, the opposite side of two described limiting frame is slidably connected with slider, two described sliders are fixedly connected with fixed frame, the side of the fixed frame is fixedly connected with two support plates, the inner wall of the fixed frame is fixedly connected with locating frame, the inner wall of the locating frame is fixedly connected with hydraulic telescopic rod on both sides, test piece is fixed on clamping piece by fixing bolt, without welding, when the same inner diameter test piece is tested, clamping piece can be reused, at the same time, test piece is fixed by a plurality of fixing bolts, compared with the fixation of test piece in the prior art, it is more stable, improves the use effect, and is convenient for the fixation of test piece with different wall thickness, expands the use range.
