Abstract
The invention discloses a self-centering clamp device of a hydrostatic test unit for steel pipes. The self-centering clamp device comprises a clamp, a fixed support, a guide shaft, a pipe clamping component, a transmission device, a sliding bush, and a power mechanism. Both ends of the guide shaft are connected with the fixed support. Both the clamp and the fixed holder are disposed on a main unit of a hydrostatic press. The power mechanism is disposed below the clamp. An output end of the power mechanism is connected with the sliding bush of the clamp through a connector. The sliding bush is connected with the transmission device. The pipe clamping component is disposed above the guide shaft through a connecting device. The pipe clamping component is capable of moving back and forth on the guide shaft. The connecting device is connected with the transmission device below the guide shaft. The self-centering clamp device is reliable in structure, convenient to adjust, and capable of positioning and clamping at two stations. A gear rack is used as a transmission medium, synchronous transmission ratio is accurate, and displacement for the completion of self-centering is accurate. The clamp is guided by a guide bar. An oil cylinder or gas cylinder is used for driving to complete self-clamping.
