[0003] The cutting machine in a traditional CNC lathe is controlled by a CNC system. The operation of the cutting machine mainly includes the rotation of the tool and the feed movement of the workpiece. The tool in the cutting machine is driven by the spindle.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a CNC lathe lifting device, including a support platform 1, a cylinder 2 is fixedly connected inside the support platform 1, a hollow block 3 is fixedly connected to the output end of the cylinder 2, a rotating column 4 is rotatably connected inside the hollow block 3, a gear 5 is fixedly connected to the outer wall of the rotating column 4, a slide block 6 is fixedly connected to the side wall of the support platform 1, a slide block 2 7 is fixedly connected to the side wall of the slide block 6, the rotating column 4 is slidably connected inside the slide block 6, a rack 8 is fixedly connected to the side wall of the support platform 1, the gear 5 is meshed with the rack 8, a rack 2 9 is slidably connected inside the slide block 2 7, the rack 2 9 is meshed with the gear 5, and an auxiliary component is arranged on the upper surface of the support platform 1;

[0025] Specifically, the output end of the cylinder 2 controls the rise of the hollow block 3. This process is not only stable, but also has a wide adjustment range, which can meet the processing requirements of workpieces of different heights. When the hollow block 3 rises, it will drive the rotating column 4 to slide smoothly inside the slide block 6, which cleverly utilizes the guiding effect of the slide block 6 to ensure the stability and accuracy of the movement of the rotating column 4. At the same time, the movement of the hollow block 3 will also drive the gear 5 to rotate on the side wall of the rack 8 meshing with it. Here, the rotation of the gear 5 is achieved by meshing with the rack 8. This transmission method ensures the cutting The accuracy and stability of the height adjustment of the cutting machine 10, as the gear 5 rotates, the rack 29 meshing therewith will also slide inside the slide block 27, and the slide block 27 also plays a guiding and stabilizing role, ensuring the smoothness and accuracy of the movement of the rack 29. The sliding of the rack 29 further drives the lifting and lowering of the cutting machine 10, thereby realizing the adjustment of the height of the cutting machine 10. In this way, we can easily adjust the height of the cutting machine 10 to adapt to workpieces of different heights, which not only improves the processing range of the cutting machine 10, but also improves the processing accuracy and efficiency of the workpiece.

[0026] Reference Figure 1 , Figure 3 and Figure 4 The auxiliary component includes a workbench 11, which is fixedly connected to the upper surface of the support table 1, a support block 12 is fixedly connected to the side wall of the rack 29, a cylinder 2 13 is fixedly connected to the side wall of the support block 12, a tilting block 14 is fixedly connected to the output end of the cylinder 2 13, a sliding column 15 is slidably connected to the inside of the support block 12, the tilting block 14 fits with the sliding column 15, the tilting block 14 is slidably connected to the inside of the support block 12, a connecting column 17 is fixedly connected to the inside of the support block 12, a support block 2 16 is slidably connected to the outer wall of the connecting column 17, the support block 2 16 fits with the support block 12, a hollow column 18 is fixedly connected to the upper surface of the support block 12, one end of a spring 19 is fixedly connected to the inside of the hollow column 18, the other end of the spring 19 is fixedly connected to the inside of the sliding column 15, and the sliding column 15 is slidably connected to the inside of the hollow column 18;

[0027] Specifically, the operation is performed through the output end of the cylinder 2 13, and the output end of the cylinder 2 13 is connected to the tilting block 14. When the cylinder 2 13 is started, it will pull the tilting block 14 to slide inside the support block 12. This sliding cleverly uses the mechanical principle to make the entire operation process simple and reliable. The inclined surface fit between the tilting block 14 and the sliding column 15 is the key to this mechanism. When the tilting block 14 slides inside the support block 12, due to the design of the inclined surface, the movement of the tilting block 14 will directly lead to the decline of the sliding column 15. This inclined surface fit design not only reduces friction and improves sliding efficiency, but also through the automatic centering effect of the inclined surface, it also ensures that the sliding column 15 can accurately descend along the predetermined trajectory. The descent of the sliding column 15 will cause the spring 19 to rebound. The spring 19, as an elastic element, plays a role of buffering and resetting here.

[0028] Reference Figure 1 , Figure 3 and Figure 4 The side wall of the hollow column 18 is rotatably connected with a rotating block 20, one end of the rotating block 20 is in contact with the upper surface of the supporting block 16, and the other end of the rotating block 20 is in contact with the sliding column 15, and the side wall of the supporting block 16 is fixedly connected with the cutting machine 10;

[0029] Specifically, the synergistic effect of the sliding column 15 and the rotating block 20 is the key link in realizing the replacement or maintenance of the cutting machine 10. When the sliding column 15 is operated and moved, it will compress the rotating block 20, causing it to rotate on the side wall of the hollow column 18. This cleverly utilizes the principle of mechanical transmission to convert the sliding action into a rotating action, thereby achieving the purpose of the operation. When the rotating block 20 is compressed by the sliding column 15 and begins to rotate, one end of it will break away from the constraint of the fixed support block 16. At this time, the cutting machine 10 originally locked by the fixed support block 16 gains freedom, and the operator can easily pull the support block 16 to realize the replacement or maintenance operation of the cutting machine 10.

[0030] Working principle: When the staff needs to replace or overhaul the cutting machine 10, first pull the tilting block 14 through the output end of the cylinder 2 13 to slide inside the support block 12. Since the tilting block 14 and the sliding column 15 are in an inclined fit, the movement of the tilting block 14 will cause the sliding column 15 to drop. The drop of the sliding column 15 will pull the spring 19 to extend it, and the sliding column 15 will press the rotating block 20 to rotate on the side wall of the hollow column 18. At this time, one end of the rotating block 20 is no longer fixed to the support block 2 16, and the support block 2 16 can be pulled to leave the connection The outer wall of the column 17, and then the cutting machine 10 can be replaced or repaired. When the height of the cutting machine 10 needs to be adjusted, the hollow block 3 is first driven to rise through the output end of the cylinder 2. The movement of the hollow block 3 will drive the rotating column 4 to slide inside the slide block 6, and will also drive the gear 5 to rotate on the side wall of the rack 8 meshing with it. The rotation of the gear 5 will drive the rack 29 meshing with it to slide inside the slide block 27, and the sliding of the rack 29 will drive the cutting machine 10 to rise and fall. At this time, the height of the cutting machine 10 can be adjusted to adapt to workpieces of different heights.
