In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

As shown in fig. 1 to 4, the present invention provides a hydraulic clamp with high positioning efficiency, which is mainly used for plate-shaped workpieces, and comprises a workbench 10, a support plate 20, a clamping mechanism 30, a pressing mechanism 40 and an external control box.

The top of the working table 10 is provided with an electric turntable 11.

The supporting plate 20 is transversely disposed above the electric turntable 11 and is fixedly connected to the electric turntable 11 through a plurality of supporting columns 21.

The clamping mechanism 30 is used for clamping a workpiece, and the clamping mechanism 30 comprises a guide rail 31, a clamping plate 32 and a bidirectional screw rod 33. The guide rail 31 is installed on the top of the power disc 11.
