The invention belongs to the technical field of under-pressure operation, and discloses an under-pressure operation test
system which comprises a feeding device, a material moving device, a discharging device and an under-pressure operation device which are arranged in sequence. The feeding device accommodates the
pipe fittings. The material moving device can move the
pipe fitting to the to-be-grabbed position, and the material placing device can grab the
pipe fitting at the to-be-grabbed position. The under-pressure operation device is arranged below the discharging device and comprises a lifting driving
assembly, a bearing base, a rotating driving
assembly and a clamping jaw
assembly, the lifting driving assembly is arranged below the discharging device, the bearing base is connected to the output end of the lifting driving assembly, and the clamping jaw assembly is rotationally arranged on the bearing base and can receive the pipe fittings on the discharging device. The
pipe fitting is arranged in the clamping jaw assembly in a penetrating mode in the axial direction, and the rotation driving assembly is connected to the clamping jaw assembly and can drive the clamping jaw assembly to rotate so that the
pipe fitting can be connected to a target position in a screwed mode. According to the under-pressure operation test
system, the matching integrity, the operation efficiency and the
automation degree can be improved, and the operation difficulty of operators is reduced.
