At the same time, when the first motor 204 is started during processing, the output shaft of the first motor 204 rotates and drives the first screw rod 203 to rotate. The first screw rod 203 rotates the thread to drive the mounting plate 202 to slide on the slide 201, and the mounting plate 202 drives the tool holder 205 to move. At the same time, the mounting plate 202 is connected to the mounting block 206. The photoelectric sensor 207 is driven to move. The photoelectric sensor 207 detects the position of the workpiece by emitting light and receiving reflected light. When the light is irradiated on the workpiece, part of the light will be reflected back. The photoelectric sensor 207 receives the reflected light and converts it into an electrical signal.

When it moves to a certain position, the fourth motor 409 is started. When the output shaft of the fourth motor 409 rotates, it drives the fourth screw rod 408 to rotate. Since the threads at both ends of the fourth screw rod 408 are in opposite directions, the fourth screw rod 408 will simultaneously drive the two connecting blocks 404 to slide toward each other. When the connecting blocks 404 slide toward each other, they drive the mounting seat 405 to move toward each other.

When the connecting plate 502 moves downward to a certain position, the installation frame 301 moves, so that the fixed shaft 503 drives the cleaning brush 504 to be located in the three-jaw chuck 7, and then the three-jaw chuck 7 is driven to rotate by the fifth motor 8, so that the cleaning brush 504 cleans the waste on the clamping jaws of the three-jaw chuck 7.

Since the second hose 509 on the air intake port of the vacuum pump 508 is connected to the top of the filter screen 511, and the first hose 507 is connected to the bottom of the filter screen 511, the smaller waste cleaned will be sucked out from the fixed pipe 505 and the first hose 507 is sucked to the bottom of the filter screen 511, and the waste chips on the jaws of the three-jaw chuck 7 are cleaned by the cleaning brush 504 to prevent the waste chips from being clamped between the three-jaw chuck 7 and the workpiece during the process of clamping the workpiece.

Subsequently, only the waste chips in the collection frame 603 need to be processed.

[0037] When the present invention is in use, during material loading, firstly, the third motor 308 is started, and the output shaft of the third motor 308 drives the third screw rod 307 to rotate when it rotates. When the third screw rod 307 rotates, the thread drives the slide rod 302 to slide. When the slide rod 302 slides, it moves more smoothly through the guide rod 311.

When it moves to a specified position, a metal shaft is placed in the electromagnetic suction cup 305, and the electromagnetic suction cup 305 is started so that the metal shaft is adsorbed on the electromagnetic suction cup 305. Then, the electromagnetic suction cup 305 is driven to move inwardly through the slide rod 302. When it moves to a certain position, the first hydraulic rod 306 is started, and the telescopic end of the first hydraulic rod 306 is extended to drive the electromagnetic suction cup 305 to move downward. When the electromagnetic suction cup 305 moves downward, the connecting rod 304 and the installation sleeve 303 slide and cooperate, so that the electromagnetic suction cup 305 moves more smoothly. When the metal shaft moves downward to a certain position, by starting the second hydraulic rod 310, the telescopic end of the second hydraulic rod 310 is extended to drive the installation frame 301 to move. When the installation frame 301 moves, it will slide with the guide plate 309. The setting of the guide plate 309 makes the installation frame 301 move more smoothly. At the same time, the installation frame 301 drives the metal shaft to move, so that one end of the metal shaft is located in the three-jaw chuck 7, and then the metal shaft is clamped by the three-jaw chuck 7. Through the cooperation of the installation frame 301, the sliding rod 302 and the electromagnetic suction cup 305, it is convenient to realize fast and automatic feeding of the metal shaft, thereby improving the feeding efficiency and operation flexibility.

[0038] At the same time, during processing, by starting the first motor 204, the output shaft of the first motor 204 rotates and drives the first screw rod 203 to rotate. The first screw rod 203 rotates the thread to drive the mounting plate 202 to slide on the slide 201. The mounting plate 202 drives the tool holder 205 to move. At the same time, the mounting plate 202 drives the photoelectric sensor 207 to move through the mounting block 206. The photoelectric sensor 207 detects the position of the workpiece by emitting light and receiving reflected light. When the light is irradiated on the workpiece, part of the light will be reflected back. The photoelectric sensor 207 receives the reflected light and converts it into an electrical signal. According to the reflected light, the workpiece is moved. The distance between the workpiece and the photoelectric sensor 207 can be calculated by the intensity and time, so as to realize the positioning of the workpiece. When the photoelectric sensor 207 detects the position of the workpiece, the numerical control system will start the fifth motor 8 through the controller control. When the output shaft of the fifth motor 8 rotates, it drives the three-jaw chuck 7 to rotate. When the three-jaw chuck 7 rotates, it drives the metal shaft to rotate. When the metal shaft rotates, it can cooperate with the tool on the tool holder 205 to cut the metal shaft. At the same time, by starting the second motor 212, the output shaft of the second motor 212 rotates, it drives the second screw rod 211 to rotate. When the second screw rod 211 rotates, the thread drives the slider The slide block 209 is slidably connected in the guide frame 210. When the slide block 209 slides, the fixed plate 208 is driven to move. When the fixed plate 208 moves, the position of the tool holder 205 is adjusted. The position of the tool holder 205 is adjusted by the mounting plate 202 and the slide seat 201, so as to process the metal shaft. During processing, the third hydraulic rod 401 can be started. When the telescopic end of the third hydraulic rod 401 is extended, the adjustment rod 402 is driven to move. The adjustment rod 402 will drive the adjustment frame 403 to move. When the adjustment frame 403 moves, the fixed rod 410 and the fixed sleeve 411 cooperate to move, so that the adjustment frame 403 moves. More stable, when the movement reaches a certain position, the fourth motor 409 is started, and the output shaft of the fourth motor 409 rotates to drive the fourth screw rod 408 to rotate. Since the threads at both ends of the fourth screw rod 408 are in opposite directions, the fourth screw rod 408 simultaneously drives the two connecting blocks 404 to slide toward each other, and the connecting blocks 404 slide toward each other to drive the mounting seats 405 to move toward each other, and the mounting seats 405 move to drive the connecting rollers 407 to clamp the metal shaft, so that the metal shaft rotates more stably. At this time, the metal shaft will not swing due to the centrifugal force when rotating, thereby avoiding affecting the processing of the metal shaft;

[0039] When the processing is completed, the material can be unloaded through the electromagnetic suction cup 305. After the unloading is completed, by starting the fourth hydraulic rod 501, the telescopic end of the fourth hydraulic rod 501 is extended to drive the connecting plate 502 to move. When the connecting plate 502 moves downward to a certain position, the installation frame 301 moves, so that the fixed shaft 503 drives the cleaning brush 504 to be located in the three-jaw chuck 7, and then the three-jaw chuck 7 is driven to rotate by the fifth motor 8, so that the cleaning brush 504 cleans the waste chips on the clamping jaws of the three-jaw chuck 7. During cleaning, the vacuum pump 508 is started. Since the second hose 509 on the suction port of the vacuum pump 508 is connected to the top of the filter screen 511, and the first hose 507 is connected to the bottom of the filter screen 511, the cleaning Smaller waste chips will be sucked from the fixed tube 505 and the first hose 507 to the bottom of the filter screen 511, and the waste chips on the jaws of the three-jaw chuck 7 will be cleaned by the cleaning brush 504 to prevent the waste chips from being clamped between the three-jaw chuck 7 and the workpiece during the process of clamping the workpiece. As the three-jaw chuck 7 is tightened, the waste chips will scratch the surface of the workpiece and damage the smoothness of the workpiece. At the same time, when the waste chips at the bottom of the filter screen 511 need to be processed, the fifth hydraulic rod 601 is started, and the telescopic end of the fifth hydraulic rod 601 contracts to drive the scraper 602 to move, so that the scraper 602 scrapes off the waste chips at the bottom of the filter screen 511, and the waste chips will fall into the collection frame 603 for collection. Subsequently, only the waste chips in the collection frame 603 need to be processed.
