[0025] Please refer to Figure 1 、 3 、 4, 6. In the embodiment of the invention, a numerically controlled milling machine for machining a chip - discharging type engine bracket includes a main body 1. Chip removal bases 3 are arranged on both sides inside the main body 1. Chutes 302 are arranged on both sides of the top of the chip removal base 3. A circulating chute 304 is arranged on the inner wall of the chute 302. A telescopic slider 502 is slidably connected inside the chute 302. The second driving wheel 504 drives the screw 505 to rotate. The screw 505 drives the telescopic slider 502 to move. The telescopic slider 502 drives the slide plate 5 to move. The slide plate 5 drives the cleaning ring 506 to move. A slide plate 5 is arranged on the top of the telescopic slider 502. A slide post 501 is arranged inside the slide plate 5. A cleaning ring 506 is arranged in the middle of the bottom of the slide plate 5. The cleaning ring 506 contacts the spiral blade in the screw barrel 404 to clean the iron chips on the surface of the screw barrel 404. And the shape of the cleaning ring 506 can be designed according to the shape of the spiral blade in the screw barrel 404. Screws 505 and slide bars are respectively arranged on both sides inside the chip removal base 3;

[0026] At the end of the screw 505, a second transmission wheel 504 is fixed. A chain 503 is arranged outside the second transmission wheel 504. When the first transmission wheel 401 rotates, it drives the chain 503 to rotate. The chain 503 drives the second transmission wheel 504 to rotate. One end of the slide plate 5 is provided with a spring 507. The slide post 501 is slidably connected to the inside of the circulating chute 304. When the slide plate 5 moves to the end of the chute 302, the slide post 501 in the slide plate 5 will be squeezed by the circulating chute 304, causing the slide plate 5 to move upward. The slide plate 5 drives the cleaning ring 506 to move upward, thus leaving the surface of the screw barrel 404. The top of the slide post 501 is arranged outside the screw 505, and the outside of the screw 505 is connected to the bottom of the slide plate 5. At one end of both sides of the chip removal base 3, sliding posts 301 are provided, and a chip removal groove 303 is arranged at the bottom inside the chip removal base 3.

[0027] In this embodiment: When the first transmission wheel 401 rotates, it drives the chain 503 to rotate. The chain 503 drives the second transmission wheel 504 to rotate. The second transmission wheel 504 drives the screw 505 to rotate. The screw 505 drives the telescopic slider 502 to move. The telescopic slider 502 drives the slide plate 5 to move. The slide plate 5 drives the cleaning ring 506 to move, so that the cleaning ring 506 contacts the spiral blade in the screw barrel 404, and the iron chips on the surface of the screw barrel 404 are cleaned. Moreover, the shape of the cleaning ring 506 can be designed according to the shape of the spiral blade in the screw barrel 404. When the slide plate 5 moves to the end of the chute 302, the slide post 501 in the slide plate 5 will be squeezed by the circulating chute 304, causing the slide plate 5 to move upward. The slide plate 5 drives the cleaning ring 506 to move upward, thus leaving the surface of the screw barrel 404. When the slide plate 5 moves upward, the bottom of the slide plate 5 will expand and contract with the slide post 501. When the slide plate 5 expands and contracts upward, it will stop connecting with the screw 505, causing the spring 507 to pull the slide plate 5, making the slide plate 5 slide back to its original position and reset through the circulating chute 304, thus realizing circulation.

[0028] Please refer to Figures 2, 3, 5, and 6 with emphasis. One end of the chip removal base 3 is equipped with a motor 4. Outside the output end of the motor 4, a first driving wheel 401 is fixed, and at the end of the output end of the motor 4, a gear 402 is fixed. The outside of the first driving wheel 401 is connected to the inside of a chain 503. Inside a screw barrel 404, a rotating shaft 6 is arranged. Outside the rotating shaft 6, multiple eccentric blocks 601 are arranged. The toothed rod 603 rotates to drive the small rotating shaft 6 to rotate through a second tooth groove 602, causing the small rotating shaft 6 to rotate rapidly. When the rotating shaft 6 rotates, it drives the multiple eccentric blocks 601 to rotate, causing the screw barrel 404 itself to vibrate. At the other end outside the rotating shaft 6, a second tooth groove 602 is arranged. Outside the second tooth groove 602, a toothed rod 603 that meshes first is arranged. When the screw barrel 404 rotates, it drives the medium-sized toothed rod 603 to rotate through a first tooth groove 405 at the other end. Both ends of the rotating shaft 6 and one end of the toothed rod 603 are rotatably connected to the inner wall of the main body 1. The outside of the toothed rod 603 meshes with the first tooth groove 405 at the other end of the screw barrel 404. The motor 4 drives the first driving wheel 401 and the gear 402 to rotate. The gear 402 rotates to drive the screw barrel 404 to rotate to transport iron chips. And the first tooth groove 405 at the other end is arranged on the inner wall of the screw barrel 404. At the other end inside the main body 1, a conveyor belt 101 is arranged at the bottom of the chip removal base 3;

[0029] In the middle of the main body 1, a workbench 2 is arranged. On both sides of the workbench 2, corrugated sleeves 201 are arranged. On the top of the workbench 2, a fixture 202 is arranged. On the top of the fixture 202, a cutting tool 203 is arranged. Inside the chip removal base 3, at the top of a chip removal groove 303, a screw barrel 404 is arranged. At both ends of the screw barrel 404, first tooth grooves 405 are arranged. At one end of the first tooth groove 405 at one end outside the screw barrel 404, an elliptical plate 406 is fixed. At the bottom of the chip removal base 3, a roller 403 is rotatably connected. The screw barrel 404 itself vibrates. When the screw barrel 404 rotates, it drives the elliptical plate 406 to rotate. When the elliptical plate 406 rotates, the protruding position presses against the surface of the roller 403. The outside of the roller 403 is in contact with the elliptical plate 406. The elliptical plate 406 pushes the chip removal base 3, and through a sliding column 301, one end of the chip removal base 3 moves up and down to discharge the iron chips in the chip removal base 3. The first tooth groove 405 outside the screw barrel 404 meshes with the gear 402.

[0030] In this embodiment: The motor 4 drives the first transmission wheel 401 and the gear 402 to rotate. The rotation of the gear 402 drives the screw barrel 404 to rotate through the first tooth groove 405 to transport the iron filings, and the transported iron filings are discharged through the conveyor belt 101. When the screw barrel 404 rotates, it drives the medium-sized toothed rod 603 to rotate through the first tooth groove 405 at the other end, and the first tooth groove 405 at the other end is arranged on the inner wall of the screw barrel 404. The rotation of the toothed rod 603 drives the small rotating shaft 6 to rotate through the second tooth groove 602, so that the small rotating shaft 6 rotates rapidly. When the rotating shaft 6 rotates, it drives multiple eccentric blocks 601 to rotate, causing the screw barrel 404 itself to vibrate. When the screw barrel 404 rotates, it drives the elliptical plate 406 to rotate. When the elliptical plate 406 rotates, the protruding position presses against the surface of the drum 403, so that the elliptical plate 406 pushes the chip discharge base 3, and through the sliding column 301, one end of the chip discharge base 3 moves up and down to discharge the iron filings in the chip discharge base 3. Cooperating with the vibration of the screw barrel 404 itself can clean more effectively.

[0031] Working principle: The main shaft motor drives the tool to rotate, and the servo motors in the X, Y, and Z directions control the relative movement of the tool and the workpiece along a certain trajectory for cutting the workpiece. The cut iron filings fall into the chip discharge base 3. Start the motor 4 to drive the first transmission wheel 401 and the gear 402 to rotate. The rotation of the gear 402 drives the screw barrel 404 to rotate through the first tooth groove 405 to transport the iron filings, and the transported iron filings are discharged through the conveyor belt 101. When the first transmission wheel 401 rotates, it drives the chain 503 to rotate. The chain 503 drives the second transmission wheel 504 to rotate. The second transmission wheel 504 drives the screw 505 to rotate. The screw 505 drives the telescopic slider 502 to move. The telescopic slider 502 drives the slide plate 5 to move. The slide plate 5 drives the cleaning ring 506 to move, so that the cleaning ring 506 contacts the spiral blade in the screw barrel 404 to clean the iron filings on the surface of the screw barrel 404, and the shape of the cleaning ring 506 can be designed according to the shape of the spiral blade in the screw barrel 404. When the slide plate 5 moves to the end of the chute 302, the sliding column 501 in the slide plate 5 will be squeezed by the circulating chute 304, causing the slide plate 5 to move upward. The slide plate 5 drives the cleaning ring 506 to move upward and thus leave the surface of the screw barrel 404. When the slide plate 5 moves upward, the bottom of the slide plate 5 will expand and contract with the sliding column 501. When the slide plate 5 expands and contracts upward, it will stop connecting with the screw 505, and the spring 507 pulls the slide plate 5, causing the slide plate 5 to slide back to its original position and reset through the circulating chute 304, thus realizing circulation.

[0032] When the screw barrel 404 rotates, it drives the medium-sized rack 603 to rotate through the first tooth groove 405 at the other end. The first tooth groove 405 at the other end is arranged on the inner wall of the screw barrel 404. When the rack 603 rotates, it drives the small rotating shaft 6 to rotate through the second tooth groove 602, causing the small rotating shaft 6 to rotate rapidly. When the rotating shaft 6 rotates, it drives a plurality of eccentric blocks 601 to rotate, causing the screw barrel 404 itself to vibrate. When the screw barrel 404 rotates, it drives the elliptical plate 406 to rotate. When the elliptical plate 406 rotates, the protruding position presses against the surface of the drum 403, causing the elliptical plate 406 to push the chip removal base 3. Through the sliding column 301, one end of the chip removal base 3 moves up and down to discharge the iron chips in the chip removal base 3. Combining with the vibration of the screw barrel 404 itself can clean more effectively.
