[0020] Furthermore, under the action of the servo motor 2, the first limit plate 6 forms a bidirectional limit sliding structure with the operating table 1 through the bidirectional screw 3, the first sliding rod 4, the movable block 5, so that the servo motor 2 drives two groups of first limit plates 6 to extrude and limit the plate.

[0021] The first limiting plate 6 is provided with grooves at both ends, and a telescopic rod 8 is inserted into the groove. A spring 7 is provided at the bottom of the groove, and the other end of the spring 7 is connected to the inside of the telescopic rod 8. A rotating block is inserted into the other end of the telescopic rod 8, and the other end of the rotating block is connected to the fixed plate 9.

[0022] Furthermore, the telescopic rod 8 forms an elastic telescopic structure with the first limiting plate 6 in the groove through the spring 7, and the fixed plate 9 forms a rotating structure with the telescopic rod 8 through the rotating block. Therefore, when punching multiple groups of plates, the elastically telescopic fixed plate is used to facilitate the alignment and placement of the plates, and the fixed plate 9 can be used to squeeze and limit the two ends of the plates.

[0023] The first limiting plate 6 is provided with a fixing block on the outside, and a rotating rod 10 is inserted in the fixing block. Both ends of the rotating rod 10 are provided with elastic limiting blocks 11 at the upper and lower parts, and the fixing block is provided with limiting holes at the upper and lower parts respectively, and the elastic limiting blocks 11 are inserted in the limiting holes.

[0024] Furthermore, the second limiting plate 13 forms a rotating structure with the first limiting plate 6 through the rotating rod 10 and the L-shaped connecting rod 12, and the second limiting plate 13 forms an elastic locking limiting structure with the first limiting plate 6 in the limiting hole through the elastic limiting block 11, thereby facilitating the adjustment of the overall height of the limiting plate according to the thickness of the required perforated plate, thereby ensuring the limiting effect of the device on the plate.

When the support rod 14 and the support block 17 are moved, place the plate on top, thereby increasing the stability of the plate during the punching process through the support assembly, thereby avoiding damage to some plates with poor stability during the punching process; when the plate is placed, the servo motor 2 can be started, and the output shaft of the servo motor 2 drives the bidirectional screw 3 to rotate through the coupling, and the first slide bar 4 and the movable block 5 make the second slide bar 4 and the movable block 5 rotate. A limit plate 6 moves to the front and rear of the plate to squeeze and limit it. If the plate is thicker or multiple groups of plates are punched at the same time, the second limit plate 13 is rotated by the rotating rod 10, and the second limit plate 13 is engaged and limited by the elastic limit block 11, thereby increasing the overall height of the limit plate, thereby ensuring the limiting effect of the device on the plate; then the fixed plate 9 can be pulled outward, and the fixed plate 9 can be moved to the two ends of the plate by the spring 7, and the fixed plate 9 can be rotated to one side of the plate by the rotating block, thereby squeezing and limiting the two ends of the plate by the fixed plate 9, and at the same time facilitating the alignment and placement of multiple groups of plates, thereby facilitating the punching of the plate. This is the use process of the plate punching and limiting device.
