The utility model relates to an efficient tensioning, positioning and fixing clamp for round hole workpiece machining. The problem that in the prior art, manual centering is low in speed and precision, and tensioning efficiency is affected is solved. An efficient tensioning, positioning and fixing clamp for round hole workpiece machining comprises a positioning plate and a hydraulic cylinder fixedly connected to the top of the positioning plate, the top of the positioning plate is fixedly connected with an auxiliary table, one end of the auxiliary table is fixedly connected with a conical shaft sleeve, and the output end of the hydraulic cylinder is in transmission connection with a conical extrusion sleeve. The top of the positioning plate is provided with an arc-shaped placing block through an adjusting mechanism, and the surface of the extrusion sleeve is sleeved with an expansion sleeve. In the clamping process, the centering of the workpiece is determined by the conical extrusion sleeve and the shaft sle
