[0025] 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.

[0026] Reference Figures 1 to 3This utility model provides an embodiment of a CNC lathe using an electric spindle, comprising a housing 1, which serves as the external protective structure for the entire CNC lathe, protecting the precision components inside the lathe from damage and providing mounting reference surfaces for various internal mechanisms to maintain relative position accuracy and ensure machining precision. A sliding plate 2 is slidably connected to the inner side of the housing 1, allowing the conversion mechanism to move horizontally. A telescopic plate 3 is fixedly connected to the outer side of the sliding plate 2, i.e., the side away from the housing 1, for adjusting the distance between the telescopic column 4 and the sliding plate 2. A telescopic column 4 is fixedly connected to the top of the telescopic plate 3, allowing the conversion mechanism to move up and down for more precise machining. A conversion mechanism for changing machining tools is fixedly connected to the top of the telescopic column 4. An air purification mechanism is fixedly connected to the top of the housing 1, and a clamping mechanism is fixedly connected to the inner side of the housing 1.

[0027] The conversion mechanism includes a support plate 5, which supports the upper structure. A telescopic column 4 is fixedly connected to the bottom of the support plate 5, and a braking assembly is fixedly connected to the top of the support plate 5. A limiting column 12 is fixedly connected to the top of the support plate 5. The limiting column 12 is a cylindrical structure with an annular groove precisely machined on its inner wall. It is slidably connected to a small square protruding from the outer side of the sliding column 9, so that the sliding column 9 can slide smoothly inside it. At the same time, it fixes the rotating column 11 to ensure that the cutter head 13 does not deviate or shake when rotating and switching. The inner side of the limiting post 12 is rotatably connected to the rotating post 11. The outer side of the rotating post 11 is slidably connected to the sliding post 9. The sliding post 9 inside the rotating post 11 is pushed by the braking mechanism to cooperate with the limiting post 12, so that the rotating post 11 rotates and drives the cutter head 13 to switch. The outer side of the rotating post 11 is fixedly connected to four cutter heads 13. The cutter heads 13 are used for drilling and grinding of the electric spindle. The inner side of the limiting post 12 is slidably connected to the sliding post 9. The sliding post 9 is used to convert the elastic force of the spring 10 into circumferential motion in the wave groove of the rotating post 11. The inner side of the sliding post 9 is fixedly connected to the spring 10. The spring 10 is installed inside the rotating post 11 and at the connection position with the sliding post 9. During the switching of the cutter head 13, the spring 10 provides a continuous outward elastic force to the sliding post 9, so that the cutter head 13 maintains a stable position after switching to the correct position.

[0028] The braking assembly includes two limiting plates 6, which support the motor 7 and limit the rotational position of its fixed output end. The bottoms of the two limiting plates 6 are fixedly connected to the top of the support plate 5. The motor 7 is fixedly connected to the outer side of the limiting plates 6, and the motor 7 drives the rotating ring 8 to perform circular motion. The rotating ring 8 is fixedly connected to the outer side of the fixed output end of the motor 7. Under the drive of the motor 7, the rotating ring 8 pushes the sliding column 9 to slide. The inner side of the sliding column 9 is rotatably connected to the outer side of the rotating column 11, and the outer side of the spring 10 is fixedly connected to the inner side of the rotating column 11.

[0029] Reference Figure 2 , Figure 4 The purification mechanism includes a protective shell 14, which creates a clean and safe working environment for the key component of the blower 15 and transmits purified air, ensuring its long-term stable operation. The bottom of the protective shell 14 is fixedly connected to the top of the outer shell 1. The blower 15 is fixedly connected inside the protective shell 14. The rotating impeller inside the blower 15 creates airflow within a volute-shaped air duct, generating a stable and strong negative pressure suction at the air inlet. This rapidly draws in air containing metal shavings, fine dust, and other pollutants from the processing area into the purification mechanism for purification before discharge. An air inlet column 16 is fixedly connected to the bottom of the blower 15. The outer side of the air inlet column 16 is fixedly connected to the inner side of the outer shell 1. The air inlet column 16 protects the filter screen 17 and is connected to the outer shell 1. The filter screen 17 is fixedly connected to the inner side of the air inlet column 16. The filter screen 17 ensures preliminary filtration and interception of the intake air, preventing large particles and foreign objects from directly impacting the impeller of the blower 15 and causing damage. The top of the filter screen 17 is fixedly connected to the bottom of the blower 15. An activated carbon filter column 18 is fixedly connected inside the filter screen 17. The activated carbon inside the activated carbon filter column 18 effectively removes pollutants such as volatile organic compounds and oil mist from the air by means of microporous adsorption, further purifying the air and ensuring that the gas discharged from the purification unit is clean and odorless, thus protecting the health of the operators. The top of the activated carbon filter column 18 is fixedly connected to the bottom of the blower 15.

[0030] Reference Figure 2 , Figure 5The fixing mechanism includes a second motor 19, which drives the fixing mechanism to perform circular motion. The outer side of the second motor 19 is fixedly connected to the inner side of the outer casing 1. The fixed output end of the second motor 19 is fixedly connected to a second rotating ring 20, which transmits the rotational force of the second motor 19 to a limiting ring 21. The outer side of the second rotating ring 20 is fixedly connected to the limiting ring 21, which is used to connect and limit the internal structure. The inner side of the limiting ring 21 is fixedly connected to a third motor 22, which drives a first gear 23 to perform circular motion. The fixed output end of the motor 22 is fixedly connected to a gear 23, which drives the rotating ring 24 to rotate. The inner side of the limiting ring 21 is rotatably connected to the rotating ring 24. When the rotating ring 24 rotates, the groove on its outside drives the sliding ring 25 to slide along a specific trajectory of the limiting ring 21. The outer side of the rotating ring 24 is meshed with the outer side of the gear 23. The outer side of the rotating ring 24 is slidably connected to the sliding ring 25. When the sliding ring 25 slides, the outer ring fixes the electric spindle.

[0031] Working Principle: When machining the electric spindle on a CNC lathe, the sliding plate 2 slides inside the housing 1, while the telescopic plate 3 and telescopic column 4, along with the support plate 5, adjust the position of the switching mechanism to facilitate machining. When it is necessary to switch machining tools, the motor 7, limited by the limit plate 6, drives the rotating ring 8 to perform circular motion. The rotating ring 8 pushes the small square on the outside of the sliding column 9 to slide in the groove inside the limit column 12. Under the restriction of the limit column 12, the sliding column 9 can only move in a straight line, and the small square on the inside of the sliding column 9 is slidably connected to the wave-shaped groove on the outside of the rotating column 11. The sliding column 9 converts its own linear motion into the circular rotation of the rotating column 11. When the rotating column 11 rotates around its axis, the four tool heads 13 change position accordingly. During the tool head 13 switching process, the spring 10 installed inside the rotating column 11 at the connection position with the sliding column 9 plays a role, providing outward elastic force to the sliding column 9 to overcome mechanical backlash and possible vibration interference.

[0032] When the CNC lathe is machining the electric spindle, the purification mechanism simultaneously enters its working state. The blower 15 inside the protective housing 14 starts operating, and the motor inside 15 drives the impeller to rotate at high speed within the volute-shaped air duct. Based on aerodynamic principles, the impeller's rotation causes rapid airflow, thereby generating a stable and strong negative pressure suction at the air inlet. The air inlet column 16 connects to the lathe's machining area, drawing in metal shavings and fine dust generated during machining. After initial filtration by the filter screen 17, the air further purifies through the activated carbon in the activated carbon filter column 18 using microporous adsorption. The purified air is then discharged under the action of the blower.

[0033] When the CNC lathe is preparing to process a workpiece, motor 219 drives rotating ring 20 to perform circular motion. Since rotating ring 20 is tightly fixed to limiting ring 21, limiting ring 21 also rotates synchronously. Simultaneously, motor 32 drives gear 23 to rotate, which meshes tightly with the outer side of rotating ring 24. Rotating ring 24 also rotates with gear 23. As rotating ring 24 rotates, the groove structure on its outer side slides against sliding ring 25, passing the limit of limiting ring 21. The circular motion of rotating ring 24 is converted into linear sliding of sliding ring 25. By adjusting the spacing and position of these components, until the outer annular clamping surface is in close contact with the electric spindle, friction and mechanical limiting forces firmly fix the electric spindle in place.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
