[0029] A limiting die for punching holes in a sponge includes a base 100, and vertical brackets 101 are fixedly arranged around the top of the base 100;

[0030] An installation block 200 is horizontally movably arranged on the bracket 101 through a translation mechanism. A vertical electric push rod 201 is fixedly arranged on the top of the installation block 200. The output rod of the electric push rod 201 slidably penetrates through the top of the installation block 200 and the installation frame 203 and a fixed plate 202 is arranged at the bottom end. The installation frame 203 is in an inverted U shape below the installation block 200. Vertical sliding openings 204 are symmetrically opened on the left and right sides of the installation frame 203. A vertical sliding rod 205 is fixedly arranged between the upper and lower walls of each sliding opening 204. A horizontal lifting plate 206 is slidably arranged between the rod bodies of the two sliding rods 205. The bottom of the fixed plate 202 is fixed at the center of the top of the lifting plate 206. A vertical motor 208 is fixedly arranged at the center of the bottom of the lifting plate 206. The output shaft of the motor 208 is connected with a vertical drill bit 209 through a coupling. A horizontal connecting plate 210 is fixedly arranged at the bottom of the installation frame 203. Two vertical second springs 211 are symmetrically fixedly arranged on both sides of the bottom of the connecting plate 210. A horizontal pressing plate 212 is jointly arranged at the bottom of the two second springs 211. The lower end of the drill bit 209 penetrates through the bottom wall of the pressing plate 212 with a gap;

[0031] A mirror-image "冂"-shaped placement table 300 is slidably arranged in the front-back direction below the pressing plate 212 at the top of the base 100. A fixing frame 301 is fixedly arranged on the left side of the placement table 300, and a transverse first screw rod 302 is screwed through the right side wall in a penetrating manner. A leftward end of the first screw rod 302 is rotatably provided with an inverted "L"-shaped movable frame 303. Vertically arranged second screw rods 304 are screwed through the tops of the movable frame 303 and the fixing frame 301 at intervals. A pressing block 305 for pressing the sponge is arranged at the lower end of each second screw rod 304, and a second knob 306 is fixedly arranged at the upper end.

[0032] Among them: The translation mechanism includes a transverse screw rod 102 rotatably arranged between two brackets 101 and a guide rod 103 parallel to the screw rod 102 fixed between the other two brackets 101. Movable blocks 104 protrude from the front and rear side walls of the mounting block 200. A rod body of one movable block 104 is threadedly penetrated by the rod body of the screw rod 102 in a driving manner, and a rod body of the other movable block 104 is slidably penetrated by the rod body of the guide rod 103. A first knob 105 is fixedly arranged in the extending direction of one end of the screw rod 102. By driving the screw rod 102 to rotate through the first knob 105, the mounting block 200 is translated, so as to adjust the left-right position of the drill bit 209;

[0033] Among them: Vertically arranged telescopic rods 213 are symmetrically fixedly arranged between the connecting plate 210 and the pressing plate 212. A rod body of the telescopic rod 213 is located inside the coil of the second spring 211. The telescopic rod 213 can be telescoped as the second spring 211 is compressed, and the telescopic rod 213 arranged can reduce the possibility of the second spring 211 bending;

[0034] Among them: A circular sliding hole 214 is opened at the center of the top wall of the mounting frame 203. An output rod of the electric push rod 201 slidably penetrates the inside of the sliding hole 214. An outer diameter of the fixing plate 202 is larger than an inner diameter of the sliding hole 214, ensuring that the output rod of the electric push rod 201 is not separated from the mounting frame 203;

[0035] Among them: Through holes 215 are opened at the centers of the upper and lower walls of the connecting plate 210 and the pressing plate 212. An inner diameter of the through hole 215 is larger than outer diameters of the motor 208 and the drill bit 209, facilitating the entry and exit of the drill bit 209;

[0036] Among them: A slide rail 307 protrudes from the top of the base 100 along the front-back sliding direction of the placement table 300. The slide rail 307 is in a "T" shape. A chute 308 for slidably inserting into the corresponding slide rail 307 is concavely arranged at the bottom of the placement table 300. The placement table 300 slides in the front-back direction along the slide rail 307 through the chute 308, so as to adjust the front-back position of the sponge and the drill bit 209;

[0037] Wherein: a limiting rod 309 parallel to the first screw 302 is slidably provided through the right side wall of the placement platform 300. By rotating the first screw 302, the distance between the movable frame 303 and the left side inside the placement platform 300 can be adjusted, thereby fixing the two sides of the sponge of different widths.

[0038] In practical use, the sponge to be drilled is placed on top of the placement platform 300. The first screw 302 is rotated to adjust the distance between the movable frame 303 and the left side of the placement platform 300, thus fixing the sponges of different widths on both sides. Then, the second screw 304 is rotated to adjust the height of the pressure block 305, causing the pressure block 305 to press down and fix the top left and right sides of the sponge, further securing the sponge. The sponge and drill bit 209 are adjusted by sliding the slide groove 308 along the slide rail 307 in the front-back direction. The first knob 105 drives the lead screw 102 to rotate, causing the mounting block 200 to move horizontally, thereby adjusting the left-right position of the drill bit 209 for drilling. When the electric actuator 201 is activated, the output rod drives the fixed plate 202 to descend. The fixed plate 202 pushes the lifting plate 206, along with the mounting bracket 203 and the connecting plate 210, to descend as a whole. When the pressure plate 212 touches the surface of the sponge, the output rod of the electric actuator 201 continues to descend. At this time, the thrust on the first spring 207 gradually increases, causing the lifting plate 206 to continue to descend, so that the lower end of the drill bit 209 touches the position of the sponge that needs to be drilled. At this time, the pressure plate 212 can press the surface of the area of ​​the sponge that needs to be drilled, reducing the possibility of unsatisfactory hole shapes due to the elasticity of the sponge when drilling. Finally, the motor 208 is activated to drive the drill bit 209 to rotate and drill holes in the sponge.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
