[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figs. 1-5 The embodiments provided by this utility model are as follows:

[0025] This application discloses a CNC lathe for bearing production, including a housing 1 and a three-jaw chuck inside the housing 1. A first gas collecting hood 2 is fixedly connected to one side of the housing 1, and an air blowing port 3 is provided on one side of the housing 1. The housing 1 and the first gas collecting hood 2 are connected through the air blowing port 3. A first air pump 4 is fixedly mounted on the top of the first gas collecting hood 2 and is connected to the first gas collecting hood 2 through an air outlet pipe. A second gas collecting hood 14 is fixedly connected to the other side of the housing 1, and an air extraction port 15 is provided on the other side of the housing 1. The housing 1 and the second gas collecting hood 14 are connected through the air extraction port 15. A second air pump 16 is fixedly mounted on the top of the second gas collecting hood 14 and is connected to the second gas collecting hood 14 through an air extraction pipe. The positions of the air blowing port 3 and the air extraction port 15 are corresponding. Corresponding to the number of openings 15, the inner cavity of the housing 1 is provided with a conveying mechanism. The conveying mechanism includes a motor 5 fixedly mounted on one side of the inner cavity of the housing 1. A PLC controller for driving the motor 5 is provided on the front of the housing 1. The output shaft of the motor 5 is fixedly connected to a first rotating shaft 6. A second rotating shaft 7 is provided on the front of the first rotating shaft 6. A drive wheel 8 is fixedly connected to the surface of the first rotating shaft 6. A driven wheel 9 is fixedly connected to the surface of the second rotating shaft 7. The drive wheel 8 and the driven wheel 9 are connected by a synchronous belt. The ends of the first rotating shaft 6 and the second rotating shaft 7 are rotatably connected to the inner wall of the housing 1 through bearings. A workpiece conveyor belt 10 and a chip conveyor belt 11 are respectively provided on both sides of the surface of the first rotating shaft 6 and the second rotating shaft 7. A workpiece bin 12 and a chip bin 13 are respectively provided on both sides of the bottom of the housing 1.

[0026] As a technical optimization of this utility model, after the workpiece is processed, it will fall onto the workpiece conveyor belt 10 along with the iron filings. At this time, through the cooperation of the first air pump 4 and the first air collecting hood 2, the air blowing port 3 will blow air evenly, thereby blowing the iron filings toward the iron filings conveyor belt 11 to separate them from the workpiece. At the same time, the second air pump 16 will generate negative pressure in the inner cavity of the second air collecting hood 14, thereby generating suction at the air extraction port 15. This generates bidirectional airflow, which can make the airflow distribution more uniform. The second air pump 16 can increase the suction of the entire system, making it easier to collect the iron filings. Meanwhile, the rotation of the workpiece conveyor belt 10 and the iron filings conveyor belt 11 can classify and discharge the workpiece and iron filings, thereby facilitating the subsequent work.

[0027] The first rotating shaft 6 and the second rotating shaft 7 can rotate together through the cooperation of the driving wheel 8 and the driven wheel 9, thereby driving the workpiece conveyor belt 10 and the iron chip conveyor belt 11 to rotate and convey the workpiece and iron chips.

[0028] A filter screen 17 is fixedly connected to the inner cavity of the second air collection hood 14. The filter screen 17 is located between the air extraction port 15 and the second air pump 16.

[0029] As a technical optimization of this utility model, the filter screen 17 can prevent iron filings from flying during the processing, which helps to maintain a clean working environment. At the same time, it can prevent iron filings from entering the second air pump 16 and causing damage to the second air pump 16, thus effectively extending its service life.

[0030] Both sides of the bottom of the box 1 are provided with through slots 18. The workpiece compartment 12 and the chip compartment 13 are connected to the inner cavity of the box 1 through the through slots 18. The inner wall of the box 1 is fixedly connected with a protective plate, and a ventilation hole is provided on one side of the protective plate.

[0031] As a technical optimization of this utility model, the through groove 18 can facilitate the discharge of workpieces and iron filings, and prevent workpieces and iron filings from accumulating at the bottom of the box 1;

[0032] The protective plate is located between the scrap conveyor belt 11 and the belt. The protective plate can shield the scrap and prevent the scrap from causing wear to the motor 5, belt, drive pulley 8 and driven pulley 9. The shape of the protective plate matches the shape of the box 1 and the box door. The bottom of the protective plate is close to the scrap conveyor belt 11 and retains a slight gap, so as to avoid interference with the scrap conveyor belt 11.

[0033] Both sides of the workpiece bin 12 and the chip bin 13 are fixedly connected with locking blocks 19, and the bottom of the box 1 is fixedly connected with a slot 20 that works with the locking blocks 19. The locking blocks 19 are engaged in the inner cavity of the slot 20.

[0034] As a technical optimization of this utility model, the cooperation of the card block 19 and the card slot 20 can facilitate the installation and disassembly of the workpiece bin 12 and the chip bin 13, which is simple to operate and can save a lot of time.

[0035] Working principle: After the workpiece is processed, it falls onto the workpiece conveyor belt 10 along with the iron filings. At this time, the air outlet 3 releases air with the cooperation of the first air collecting hood 2 and the first air pump 4, while the air extraction outlet 15 draws in air with the action of the second air collecting hood 14 and the second air pump 16, thus forming a two-way airflow to ensure that the iron filings in the entire processing area can be effectively removed. At this time, most of the iron filings will move onto the iron filings conveyor belt 11 or be discharged directly through the through groove 18. Subsequently, the motor 5 drives the first rotating shaft 6 to rotate, which in turn causes the second rotating shaft 7 to rotate together with the cooperation of the driving wheel 8 and the driven wheel 9. At this time, the workpiece conveyor belt 10 and the iron filings conveyor belt 11 will also rotate synchronously, and the workpiece and iron filings will be put into the inner cavity of the workpiece bin 12 and the iron filings bin 13 through the through groove 18, respectively. This can reduce the labor intensity of the operator and improve work efficiency.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
