When the second motor 302 is started, the second motor 302 can drive the half gear 307 to rotate, and the half gear 307 is fixedly connected to the conveying roller 301. A conveyor belt 303 is installed on the surface of the conveying roller 301. The rotation of the half gear 307 can drive the conveying roller 301 to rotate, and then drive the conveyor belt 303 to move. Under the action of the second motor 302, the conveyor belt 303 maintains a uniform motion, and the conveyor belt 303 is moved. In order to enable the steel plate placed on the surface of the conveyor belt 303 to be transported at a uniform speed, a fixed groove 304 is provided on the surface of the conveyor platform 1, a positioning block 305 is slidably installed inside the fixed groove 304, a spring 306 is installed inside the fixed groove 304, the spring 306 is arranged between the fixed groove 304 and the positioning block 305, a connecting rod 308 is fixedly installed on the right bottom of the positioning block 305, a first tooth plate 309 is fixedly installed on the end of the connecting rod 308, the first tooth plate 309 is meshed with the half gear 307, a second tooth plate 310 is fixedly installed on the left bottom of the positioning block 305, a second gear 311 is rotatably installed on the left bottom of the conveyor platform 1, the second gear 311 is meshed with the second tooth plate 310, and the side of the second gear 311 is fixedly installed A third pulley 312 is provided, and the third pulley 312 is connected to the first pulley 204 through a belt.

The rotation of the third pulley 312 can drive the first pulley 204 to rotate, and then the first rotating column 205 can be driven to rotate. In this way, the cutting knife 212 can make a circular motion, so that the steel plate can be cut. When the half gear 307 rotates to a position where it is not meshed with the first tooth plate 309, the first tooth plate 309 is no longer subjected to the force, so that the positioning block 305 returns to its original position, and the cutting knife 212 is also rotated to a high position without contacting the steel plate. At the same time, the action of the positioning block 305 returning to its original position can also push the cut steel plate to the receiving plate at the bottom of the conveyor table 1. Since the rotation speed of the half gear 307 remains consistent, the time interval of the reciprocating movement of the first tooth plate 309 can be kept consistent, and then the positioning distance of the positioning block 305 can be kept consistent, so that the time of the circular motion of the cutting knife 212 is kept consistent, and the steel plate can be cut at a fixed distance.

When the slider 215 slides on the surface of the slide rail 214, it can drive the left piston rod 407 to reciprocate inside the water pipe 403. At the same time, the movement of the slider 215 can drive the third tooth plate 408 to move, and then drive the support 410 to move, so as to drive the right piston rod 407 to move inside the water pipe 403. The movement of the two piston rods 407 can drive the two piston plates 406 to reciprocate inside the water pipe 403, so as to adjust the water in the water pipe 403.

[0040] Specifically, the working process or working principle of the steel plate cutting device that is easy to position is as follows: the staff places the steel plate on the surface of the conveyor belt 303, and then starts the second motor 302. When the second motor 302 is started, the second motor 302 can drive the half gear 307 to rotate, and the rotation of the half gear 307 can drive the conveyor roller 301 to rotate, and then drive the conveyor belt 303 to move. Under the action of the second motor 302, the conveyor belt 303 maintains a uniform speed of movement, and then the steel plate placed on the surface of the conveyor belt 303 can be transported at a uniform speed. When the half gear 307 rotates, it can drive the first The tooth plate 309 moves. When the first tooth plate 309 moves, the entire positioning block 305 can slide inside the fixed groove 304, so that the positioning block 305 compresses the spring 306. When the positioning block 305 moves, the second tooth plate 310 can be driven to move, and then the second gear 311 can be driven to rotate. The rotation of the second gear 311 can drive the third pulley 312 to rotate. The rotation of the third pulley 312 can drive the first pulley 204 to rotate, and then the first rotating column 205 can be driven to rotate. The rotation of the first rotating plate 208 can drive the first mounting frame 20 9 is rotated in a circle, and the circle rotation of the first mounting frame 209 can drive the first rotating plate 208 fixedly connected to the second rotating column 207 to rotate, and the second rotating column 207 can be driven by the first rotating plate 208 fixedly connected to the second rotating column 207 to rotate, and the rotation of the second rotating column 207 can drive the second pulley 206 to rotate, and the first mounting frame 209 is driven by the first rotating column 205 to perform reciprocating circle motion, so that the cutting knife 212 can realize reciprocating circle motion, and when the cutting knife 212 moves to contact with the steel plate, the steel plate can be cut, and when the semi-tooth When the wheel 307 rotates to a position where it is not meshed with the first tooth plate 309, the first tooth plate 309 is no longer acted upon by a force, so that the positioning block 305 returns to its original position, and the cutting knife 212 also rotates to a high position so as not to contact the steel plate. At the same time, the action of the positioning block 305 returning to its original position can also push the cut steel plate to the receiving plate at the bottom of the conveyor table 1. Since the rotation speed of the half gear 307 remains consistent, the time interval of the reciprocating movement of the first tooth plate 309 can be kept consistent, and thus the positioning distance of the positioning block 305 can be kept consistent, thereby keeping the circular motion time of the cutting knife 212 consistent, and thus the steel plate can be cut at a fixed distance.

[0041] When the entire first mounting frame 209 performs reciprocating circular motion, the sliding rod 213 can be driven to perform reciprocating circular motion, so that the sliding rod 213 can slide up and down inside the sliding block 215, and the sliding block 215 can also be driven to slide back and forth on the surface of the sliding rail 214. When the sliding block 215 slides on the surface of the sliding rail 214, the piston rod 407 on the left can be driven to perform reciprocating motion inside the water pipe 403. At the same time, the movement of the sliding block 215 can drive the third tooth plate 408 to move, and then drive the support 410 to move, so as to drive the piston rod 407 on the right to move inside the water pipe 403. The movement of the two piston rods 407 can This can drive the two piston plates 406 to move back and forth inside the water pipe 403, and then squeeze the water inside the water pipe 403, so that the water inside the water pipe 403 is sprayed out through the sprinkler head 402, so that the surface of the steel plate can be water-cooled. At the same time, the movement of the third tooth plate 408 can drive the third gear 409 to rotate, and the rotation of the third gear 409 can drive the fourth tooth plate 411 to move back and forth. Due to the limitation of the slide rail 214, the third tooth plate 408 will not contact the fourth tooth plate 411 when it moves to the far right. When the fourth tooth plate 411 moves back and forth, it can drive the grinding block 412 to move back and forth, so that the surface of the steel plate can be polished.

[0042] When the second pulley 206 rotates driven by the second rotating column 207, it can drive the fifth pulley 503 to rotate, and the rotation of the fifth pulley 503 can drive the fourth pulley 501 to rotate, and the rotation of the fourth pulley 501 can drive the sixth pulley 504 to rotate, and the rotation of the sixth pulley 504 can drive the rotating roller 505 to rotate, and the rotation of the rotating roller 505 can drive the cleaning brush 506 to rotate, so that the surface of the steel plate can be preliminarily cleaned, and when the first mounting frame 209 rotates in a circle, it can drive the fourth gear 514 to rotate in the center of the circle, and then drive the fifth gear 509 to rotate, and the rotation of the fifth gear 509 can drive the eccentric plate 510 to rotate eccentrically, and then drive the first threaded rod 511 to move up and down, so that the threaded cylinder 512 can be rotated, and then the grinding plate 516 can be driven to rotate, so that the surface of the steel plate can be preliminarily polished.
