[0030] The method of using this embodiment is as follows: pre-set the pressure value for controlling the servo motor 10 to be turned off and the indicator light 12 to be turned on by using the PLC controller 11 according to the clamping requirements of the plate; during clamping, start the servo motor 10 in the positive direction to drive the two screw rods 9 to rotate synchronously; the rotation of the two screw rods 9 drives the two lifting plates 8 to slide close to each other on the corresponding two vertical guide rods 4 respectively; the two lifting plates 8 drive the two horizontal plates 5 to move close to each other through the two springs 7 and the two pressure sensors 6 in turn; the horizontal plates 5 slide vertically on the corresponding two vertical guide rods 4; the two vertical guide rods 4 can be used for stable vertical guidance; the two horizontal plates 5 drive the two clamping plates 2 to move close to each other to clamp the plate; in the clamping state, the two lifting plates 8 that continue to move close to each other compress the two springs 7, making them change from soft to hard, so as to achieve the desired effect.

When the preset value is reached, the PLC controller 11 controls the servo motor 10 to automatically turn off and the control indicator 12 to turn on. By means of vertical guidance during clamping, detecting the clamping pressure and automatically shutting down and reminding when the preset pressure value is reached, intelligent automatic and accurate pressure control clamping of the plate is realized, and personnel can be reminded in time that the clamping is completed. The clamping force can be automatically and accurately controlled to avoid loosening due to low clamping force or clamping damage due to excessive clamping force, thereby improving the clamping stability;

Similarly, the movement direction is completely opposite to that of the forward start of the servo motor 10. At this time, the two lifting plates 8 are transformed into repulsive movement, and the compression force on the two springs 7 is relaxed. After the compression force is released, the two lifting plates 8 drive the two clamping plates 2 to repel each other through the two springs 7, the two pressure sensors 6 and the two horizontal plates 5 in turn, thereby releasing the clamping state.
