Positioning equipment for improving mounting precision of prefabricated part

The utility model belongs to the technical field of prefabricated part positioning, and particularly relates to a positioning device for improving the installation accuracy of a prefabricated part, which comprises a positioning frame, a fixing frame fixedly arranged at the top end of the positioning frame, a guide rail arranged on the surface of the bottom end of the fixing frame, a sliding rod horizontally arranged in the guide rail, and a positioning rod arranged on the sliding rod. The pushing cylinder pushes the push rod to move, so that the sliding plate slides on the sliding rod, the sliding plate slides on the guide rail in a limited mode, stable movement of the sliding plate is achieved, the sliding plate can drive a prefabricated part to move, and then the installation position of the prefabricated part can be adjusted. The use requirements for different precision are met, time and labor are saved, the hydraulic cylinder pushes the limiting rod to enter the inserting hole, the position of the wire ro
