[0059] The working principle of the utility model is as follows: when not in use and pressure is not maintained, the threaded ejector rod and ejector rod sleeve of the pressure-maintaining clamping assembly are located on the top inclined surface of the pressure-maintaining support ejector block;

[0060] When clamping and pressurizing, the clamping frame is placed on the pressurizing area of the workbench, and the frame is limited and fixed by the table clamping assembly. Then, the pencil board is placed in the clamping frame, and the moving table is driven by the moving table driving motor to move back and forth on the lower base to the corresponding position to be pressurized. Then, the pressurized top plate is driven by the pressurized hydraulic cylinder to push the pressure-maintaining top plate to move toward the clamping frame, and the pressure-maintaining clamping connecting rod moves toward the pencil board, driving the pressure-maintaining clamping plate to move toward the pencil board to clamp the pencil board. At this time, since the push rod sleeve is rotatably connected to the rotating support seat, the threaded push rod and the push rod are The rod sleeve slowly leaves the top of the pressure-maintaining support top block as the pressure-maintaining clamp plate moves, and then slides down along the inclined surface. The threaded push rod slides down to the pressure-maintaining limit block and stops. The pressure-maintaining limit block supports the bottom of the threaded push rod, and the pressure-maintaining support top block supports one end of the threaded push rod, and the pressure-maintaining clamp plate is kept stationary to continuously clamp and maintain pressure on the pencil plate. At this time, the pressurized hydraulic oil cylinder can retract the pressurized top plate to stop pressurizing. The pencil plate can be pressure-maintained without the need for continuous pressure from the pressurized hydraulic oil cylinder, which saves space for the clamp frame. The clamp frame can be moved when pressure maintenance is achieved, which is convenient for subsequent operations.

[0061] The pressure-holding clamp is then released and the clamp is released, and the pressure-holding clamp is released. The pressure-holding clamp is then released and the clamp is released, and the pressure-holding clamp is released. The pressure-holding clamp is released and the clamp is released, and the pressure-holding clamp is released. The pressure-holding clamp is released and the clamp is released.
