Fine boring hydraulic clamp for hydraulic element machining

The utility model belongs to the technical field of clamps, and particularly relates to a fine boring hydraulic clamp for hydraulic element machining, which comprises a mouth-shaped base, a U-shaped frame is movably arranged above the mouth-shaped base, first electric push rods are fixedly mounted on two side walls of the U-shaped frame, and driving ends of the first electric push rods penetrate through the U-shaped frame and extend to the inner side of the U-shaped frame. By arranging the first groove, the lead screw, the motor, the connecting block and the sliding plate, the lead screw is driven by the motor to rotate, so that the sliding plate in threaded connection with the lead screw drives the U-shaped frame to move, the clamping position of the trapezoidal clamping block is conveniently adjusted, and the position of the clamp is conveniently adjusted; the distance between the clamped hydraulic element and the fine boring tool is convenient to adjust, fine boring operation is facilitated, the arc-shaped
