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.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a multi-component nitride chemical vapor deposition (CVD) device for cutting tool surfaces, comprising a deposition chamber 1, a motor 2 fixedly mounted on the upper surface of the deposition chamber 1, a mounting block 3 fixedly mounted on the inner wall of the deposition chamber 1, a first gear 4 fixedly mounted on the outer wall of the mounting block 3, a connecting shaft 5 fixedly connected to the output end of the motor 2, a rotating frame 6 fixedly connected to the other end of the connecting shaft 5 connected to the motor 2, a first connecting rod 7 mounted on a bearing at one end of the rotating frame 6, a second gear 8 fixedly mounted on the upper outer wall of the first connecting rod 7, a third gear 9 fixedly mounted on the lower outer wall of the first connecting rod 7, a second connecting rod 10 mounted on a bearing at one end of the rotating frame 6, a fourth gear 11 fixedly mounted on the outer wall of the second connecting rod 10, a rotating block 12 fixedly mounted on the lower end of the second connecting rod 10, a mounting frame 13 fixedly connected to one end of the rotating block 12, and tool holders 14 evenly spaced on the outer surface of the mounting frame 13. The device is connected via the deposition chamber 1, motor 2, and other components. The installation includes a mounting block 3, a first gear 4, a connecting shaft 5, a rotating frame 6, a first connecting rod 7, a second gear 8, a third gear 9, a second connecting rod 10, a fourth gear 11, a rotating block 12, a mounting frame 13, a tool holder 14, and a door 15. During deposition, the motor 2 causes the connecting shaft 5 to rotate the rotating frame 6. At this time, the second gear 8, which meshes with the first gear 4, rotates the first connecting rod 7, while the third gear 9 rotates synchronously with the second gear 8. The fourth gear 11, which meshes with the third gear 9, rotates the second connecting rod 10. The rotating block 12, which is fixedly connected to the lower end of the second connecting rod 10, rotates the mounting frame 13 and the tool holder 14. At this time, the tool holder 14 rotates around the second connecting rod 10 and also around the connecting shaft 5. The cutting tools placed on the tool holder 14 have more sufficient contact with the air in the deposition box 1, resulting in better deposition effect, better quality of cutting tools, and longer service life.
[0021] Furthermore, the first gear 4 and the second gear 8 are meshed together, and the third gear 9 and the fourth gear 11 are meshed together. With the setting of the first gear 4, when the rotating frame 6 rotates, the second gear 8, which is meshed with the first gear 4, will rotate with the first connecting rod 7.
[0022] Furthermore, the second gear 8 forms a rotating structure with the rotating frame 6 via the first connecting rod 7, and the third gear 9 forms a rotating structure with the rotating frame 6 via the first connecting rod 7. With the first connecting rod 7 in place, the third gear 9 will rotate synchronously with the second gear 8 when the second gear 8 rotates.
[0023] Furthermore, the fourth gear 11 forms a rotating structure with the rotating frame 6 through the second connecting rod 10. With the setting of the fourth gear 11, when the third gear 9 rotates, the fourth gear 11, which is meshed with the third gear 9, will be rotated. At this time, the second connecting rod 10 will be rotated by the fourth gear 11.
[0024] Furthermore, the mounting bracket 13 is provided with three sets, and the tool holder 14 is installed with three sets at equal intervals on the surface of the mounting bracket 13. The surface of the tool holder 14 is provided with a slot for placing cutting tools. Through the arrangement of the tool holder 14, the tool holder 14 can be used to place cutting tools.
[0025] Furthermore, a door 15 is mounted on the bearing at the opening of the sedimentation tank 1. A sealing groove 16 is formed on the side surface of the door 15 facing the inside of the sedimentation tank 1. A first sealing ring 17 is bonded to the inner wall of the sealing groove 16. A second sealing ring 18 is bonded to the side surface of the sedimentation tank 1 that contacts the door 15. By setting the door 15, the inside of the sedimentation tank 1 can be kept in a sealed environment when the door 15 is closed, which improves the sedimentation effect.
[0026] Furthermore, the second sealing ring 18 can be embedded in the groove opened on the surface of the first sealing ring 17. With the arrangement of the first sealing ring 17 and the second sealing ring 18, the second sealing ring 18 will be embedded in the first sealing ring 17 when the door 15 is closed, thereby improving the sealing performance.
[0027] Working principle: During the deposition process, the motor 2 causes the connecting shaft 5 to rotate the rotating frame 6. At this time, the second gear 8, which meshes with the first gear 4, will rotate the first connecting rod 7, while the third gear 9 will rotate synchronously with the second gear 8. The fourth gear 11, which meshes with the third gear 9, will rotate the second connecting rod 10. The rotating block 12, which is fixedly connected to the lower end of the second connecting rod 10, will rotate the mounting frame 13 and the tool holder 14. At this time, the tool holder 14 will rotate around the second connecting rod 10 as the center, and at the same time, the tool holder 14 will also rotate around the connecting shaft 5 as the center.
