Description

Technical Field

[0001] This utility model belongs to the field of CNC lathe technology, and in particular relates to a CNC lathe lifting device. Background Technology

[0002] A CNC machine tool is a machine tool that operates using Computer Numerical Control (CNC) technology. Compared to traditional manual machine tools, CNC machine tools offer higher precision, density, and faster machining speeds, enabling the production of various parts and playing a vital role in modern manufacturing. The way CNC machine tools operate differs from manual machine tools. They do not require manual intervention to master the specific steps of each machining task. Instead, they issue instructions via a series of programmed instructions written on a computer. These instructions are interpreted by the CNC system and sent to the machine tool's motion system, which includes the spindle, tool post, feed, feed rate, and tool cutting force monitoring. This automated digital control reduces manual intervention and improves work accuracy and efficiency.

[0003] Utility model patent with publication number CN221019725U discloses a CNC lathe lifting device. This utility model includes: a lathe body; a housing disposed on the lower end face of the lathe body; a cutting device disposed on the upper inner end face of the lathe body; a lifting plate slidably installed inside the lathe body; and a lifting device disposed inside the lathe body for driving the lifting plate to rise and fall. Under the action of a screw and a first sleeve, a second sleeve can drive the lifting plate to rise and fall. When the screw stops rotating, the position of the second sleeve can be fixed, and the position of the lifting plate can also be fixed, preventing lifting fatigue and making the lifting position of the lifting plate more precise. This prevents errors in the cutting position when cutting parts, thus avoiding cost waste.

[0004] While the screw in this technology can provide some fixing effect, its low reliability in limiting the position makes it prone to displacement due to minor external forces or vibrations. In high-precision machining, CNC lathes require extremely high working accuracy; even minute errors or vibrations can lead to machining failure or even damage to the machine tool or parts. Especially during high-speed operation or machining, even slight loosening of the threaded connection can further exacerbate errors, severely affecting machining quality. Utility Model Content

[0061] a connecting plate 23 arranged on the left and right sides of the bottom plate 21;

[0062] a guide seat 24 arranged between the two connecting plates 23;

[0063] a sliding groove 25 arranged on the guide seat 24;

[0064] a sliding block 26 slidingly arranged in the sliding groove 25;

[0065] a lower clamping tooth 27 arranged on the sliding block 26, the lower clamping tooth 27 and the upper clamping tooth 22 are symmetrically distributed, and the lower clamping tooth 27 and the upper clamping tooth 22 are clamped with each other to increase the stability of the lifting mechanism 4;

[0066] The support sleeve 28 is arranged below the guide seat 24.

[0067] The screw rod 29 is threadedly arranged in the support sleeve 28, the screw rod 29 is located in the sliding groove 25, and the screw rod 29 is movably connected with the sliding block 26.

[0068] The rotating handle 210 is arranged on the screw rod 29.

[0069] In the technical solution, the lifting mechanism 4 can adjust the height of the lathe as required, adapt to different machining requirements, and improve the stability of the numerical control lathe during lifting. The clamping mechanism 2 ensures accurate positioning of the lifting mechanism 4 through cooperation of the upper clamping tooth 22 and the lower clamping tooth 27, and avoids deviation caused by external force or vibration during lifting. The upper clamping tooth 22 and the lower clamping tooth 27 are mutually clamped, a firm fixing point is formed at a proper position, the accuracy of the machine tool during machining is improved, and the machining accuracy is not affected by slight shaking or vibration. A reliable clamping scheme is provided, position deviation of the lifting mechanism 4 caused by external force or vibration is reduced, and the lifting device can stably operate during long-time high-precision machining. The clamping assembly is adjusted through rotation of the screw rod 29, and the lifting mechanism 4 can be stably located at an ideal position during each machining stage.

[0070] Work flow: the numerical control lathe starts the lifting mechanism 4, the lifting function of the lifting mechanism 4, adjusts the working height of the lathe. When the lifting mechanism 4 reaches the predetermined height, the clamping mechanism 2 starts to work. The bottom plate 21 is fixedly connected with the lifting mechanism 4, and the bottom plate 21 is provided with upper clamping teeth 22 at the bottom. The screw rod 29 is adjusted through the rotating handle 210, the screw rod 29 is threadedly connected with the supporting sleeve 28, so that the screw rod 29 moves into the sliding groove 25 of the guide seat 24, and drives the sliding block 26 to move upward along the sliding groove 25, so that the lower clamping teeth 27 are symmetrically distributed with the upper clamping teeth 22 and are clamped with each other, the upper clamping teeth 22 and the lower clamping teeth 27 fix the position of the lifting mechanism 4 through clamping, prevent the shaking or deviation of the lifting mechanism 4 due to external force or vibration, and the accuracy of the clamping ensures that the numerical control lathe maintains stable height during the working process. The screw rod 29 can finely adjust the clamping position, so as to ensure that the lifting mechanism 4 is always in an accurate and stable position. Once the clamping is completed, the clamping mechanism 2 will greatly enhance the stability of the lifting device, reduce any shaking of the lifting mechanism 4 caused by external vibration or uneven force transmission, so that the numerical control lathe can accurately process for a long time. When it is necessary to adjust the height of the lathe, the screw rod 29 rotates to drive the sliding block 26 to move, and the clamping of the lower clamping teeth 27 and the upper clamping teeth 22 is released, and then the working height of the lathe is adjusted again through the lifting mechanism 4. At this time, the clamping mechanism 2 is recombined with the upper clamping teeth 22 through the sliding block 26, so as to ensure the stability of the lifting mechanism 4 at the new height. Through the accurate clamping of the upper clamping teeth 22 and the lower clamping teeth 27, the clamping mechanism 2 effectively reduces the position deviation caused by vibration or external force during the lifting process, and ensures that the numerical control lathe can operate stably for a long time in high-precision machining. The reliability of the clamping mechanism 2 reduces the error caused by unstable lifting, greatly improves the precision of lathe machining, especially in strict high-precision operation, avoids the precision problem caused by slight shaking. The screw rod 29 adjustment mode controlled by the rotating handle 210 is simple to operate and can quickly and accurately adjust the clamping position, so as to ensure that the lathe can maintain the best stability in different machining stages. Through the accurate clamping mechanism, the stability problem of the existing lifting device in high-precision machining is solved, and it is ensured that the numerical control lathe can accurately operate in various machining processes, avoiding equipment damage or machining failure caused by unstable position.

[0071] As Figure 1 and Figure 2 shown, in the present embodiment, the optimized upper clamping teeth 22 and lower clamping teeth 27 are composed of teeth 3 and tooth grooves 31, and the teeth 3 and tooth grooves 31 of the upper clamping teeth 22 and the lower clamping teeth 27 are engaged.

[0072] In the technical solution, the engagement between the teeth 3 and the tooth grooves 31 can accurately fix the position of the lifting mechanism 4, ensuring the height stability during lifting. The mutual engagement of the teeth 3 and the tooth grooves 31 reduces the shaking or deviation of the lifting device, enhancing the reliability of the clamping. The design of the teeth 3 and the tooth grooves 31 can effectively reduce friction, prolonging the service life of the clamping components. Even under external vibration or other interference conditions, the clamping mechanism 2 can remain stable and not easily loosen, ensuring that the lifting device is always accurately locked at the desired position. Through the precise engagement of the teeth 3 and the tooth grooves 31, the upper clamping teeth 22 and the lower clamping teeth 27 can provide high-precision clamping during lifting, ensuring that the CNC lathe can maintain a stable height during machining, significantly improving the stability, precision, and durability of the CNC lathe lifting device. In high-precision machining, it can effectively prevent errors caused by unstable lifting, meeting the needs of modern manufacturing for high precision and high stability.

[0073] Embodiment 2:

[0074] The embodiment provides a CNC lathe lifting device, which has the following technical features in addition to the technical solutions of the above-mentioned embodiments.

[0075] As shown in Figure 1 and Figure 2 In this embodiment, the optimized lifting mechanism 4 includes:

[0076] The transmission shaft 41 is rotatably arranged at the upper and lower ends of the base 1.

[0077] The synchronous wheel 42 is arranged on the transmission shaft 41.

[0078] The transmission belt 43 is sleeved between the two synchronous wheels 42.

[0079] The motor 44 is arranged above the rear side of the base 1, and the output shaft of the motor 44 is connected with the transmission shaft 41.

[0080] The connecting block 45 is arranged on the transmission belt 43, and the connecting block 45 is connected with the supporting mechanism 5.

[0081] The guide rail 46 is arranged at the left and right ends of the front side of the base 1.

[0082] The guide block 47 is slidably arranged on the guide rail 46, and the guide block 47 is connected with the bottom plate 21 and the supporting mechanism 5.

[0083] In the technical solution, when the motor 44 starts, the output shaft drives the transmission shaft 41 to rotate, the transmission shaft 41 drives the synchronous wheel 42 to rotate, and then drives the transmission belt 43 to move; the movement of the transmission belt 43 is transmitted to the connecting block 45, the connecting block 45 is connected with the support mechanism 5, so that the support mechanism 5 moves up and down along the guide rail 46, ensuring that the support mechanism 5 can move stably during lifting to avoid deviation from the track. The guide block 47 plays a guiding role, ensuring that the support mechanism 5 always maintains stability in the vertical direction during lifting, avoiding unnecessary shaking or uneven lifting. The main function of the numerical control lathe lifting device is to control the lifting movement of the numerical control lathe, so that the lathe can accurately adjust the height according to the needs. This device is often used in different machining processes of numerical control lathes to ensure the height accuracy of workpiece or tool position, thereby meeting the requirements of machining precision and efficiency. The lifting device provides smooth and accurate lifting action through motor 44 drive and synchronous belt transmission, and ensures stability during lifting through guide rail 46 and guide block 47.

[0084] Example 3:

[0085] The embodiment provides a numerical control lathe lifting device, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0086] As shown in Figure 1 and Figure 3 In this embodiment, the optimized support mechanism 5 includes:

[0087] The mounting plate 51 is arranged between the front sides of the two guide blocks 47, and the mounting plate 51 is connected with the connecting block 45;

[0088] The side plate 52 is arranged at the both ends of the front side of the mounting plate 51 by means of bolt connection;

[0089] The vertical plate 53 is arranged at the both ends of the opposite sides of the two side plates 52 by means of bolt connection;

[0090] The horizontal plate 54 is arranged at the lower end of the vertical plate 53, and is used for supporting the numerical control lathe.

[0091] In the technical solution, the mounting plate 51 is located between the front sides of the two guide blocks 47 and is connected with the connecting block 45. The transmission belt 43 is connected through the connecting block 45 and the mounting plate 51, which ensures that the support mechanism 5 is synchronized with the movement of the transmission belt 43 during the lifting movement, and always maintains a stable position; at the same time, the support mechanism 5 drives the numerical control lathe to lift. During the lifting process, the mounting plate 51 plays a role in fixing the position of the support mechanism 5, ensuring that the support mechanism 5 does not dislocate within the entire lifting range. The side plate 52 is fixed at the front ends of the mounting plate 51 through bolts, which enhances the firmness of the overall structure. The vertical plate 53 is fixed at the opposite ends of the side plate 52 through bolts, and the setting of the vertical plate 53 makes the entire support structure more solid in the vertical direction; the vertical plate 53 provides additional support force, enhancing the stability of the entire structure. The main function of the vertical plate 53 is to enhance the longitudinal strength of the support mechanism 5, especially during the lifting process of the lathe, the vertical plate 53 can effectively resist the pressure in the vertical direction, preventing any structural deformation or shaking. The horizontal plate 54 is arranged at the lower end of the vertical plate 53 and is used to support the numerical control lathe. During the operation of the lifting mechanism 4, the horizontal plate 54 provides a solid foundation for the support mechanism 5, making the entire support structure have good stability in the vertical direction. The design of the horizontal plate 54 ensures the stable connection between the support mechanism 5 and the lathe, avoiding the imbalance of the lathe due to the movement during the lifting process. The combination of the components of the support mechanism 5 enables the device to withstand a large load, while also dispersing the pressure from the lifting device, avoiding concentrated stress from causing structural deformation or damage; the lifting action of the numerical control lathe can be more accurate, avoiding the influence of lifting errors on machining precision, effectively improving production efficiency and machining quality. The components of the support mechanism 5 are connected by bolts, which has good disassembly and maintenance convenience, and users can maintain and adjust them when needed, prolonging the service life of the device.

[0092] As shown in Figure 1 and Figure 3 In this embodiment, the vertical plate 53 and the horizontal plate 54 are provided with reinforcing ribs 6.

[0093] In the technical solution, the main purpose of arranging the reinforcing ribs 6 between the vertical plate 53 and the horizontal plate 54 is to enhance the structural rigidity and carrying capacity of the support mechanism 5, thereby improving the stability and reliability of the numerical control lathe lifting device during use. The introduction of the reinforcing ribs 6 can effectively prevent the vertical plate 53 and the horizontal plate 54 from bending, deforming or losing stability when subjected to external pressure during the lifting process, especially when subjected to a large load or high-speed movement, ensuring that each part of the lifting device maintains a good cooperative working state. The reinforcing ribs 6 can effectively increase the overall rigidity between the vertical plate 53 and the horizontal plate 54, preventing deformation between the two due to bearing load or external force. It makes the entire support mechanism 5 more stable during the working process, ensuring smooth lifting action of the lathe.

[0094] Embodiment 4:

[0095] The embodiment provides a numerical control lathe lifting device, in addition to comprising the technical scheme of the above embodiment, further has the following technical features.

[0096] As shown in Figure 1 and Figure 3 In this embodiment, the optimized horizontal plate 54 is provided with a damping mechanism 7, which comprises:

[0097] The fixed plate 71 is arranged between the two horizontal plates 54 on the same side.

[0098] The shock absorber 72 is arranged on the top of the fixed plate 71 on both sides.

[0099] The support plate 73 is arranged between the top of the four shock absorbers 72, which is used to support the numerical control lathe.

[0100] In this technical scheme, the main purpose of introducing the damping mechanism 7 is to reduce the vibration generated by the lifting device and the lathe itself, especially during lifting, machine operation or load change. These vibrations may affect the machining accuracy of the lathe and the long-term stability of the equipment. The damping mechanism 7 can effectively isolate and absorb these vibrations, ensure that the lathe can run in a more stable state, and thus improve the machining quality and work efficiency. The shock absorber 72 can effectively absorb the vertical or horizontal vibration generated by the lifting device through its internal elasticity and damping characteristics, reduce the transmission of these vibrations to the entire structure, and avoid the influence of vibration on the machining accuracy and stability of the lathe. During the machining process, especially when the cutting load changes greatly, the machine tool may encounter external impact force. The shock absorber 72 can help absorb these impacts to prevent them from being directly transmitted to the numerical control lathe, avoiding the occurrence of jumping or instability of the lathe during operation. The support plate 73 is connected to the top of the shock absorber 72, which ensures the support force of the lathe. Its role is to convert the energy absorbed by the shock absorber 72 into stable support force, ensuring that the lathe remains stable during vibration or impact. The damping device reduces the vibration and impact of the mechanical structure, reduces the wear and damage of the lifting device and the lathe itself, and can prolong the service life of the equipment.

[0101] Work flow: The shock absorber 72 is usually composed of elastic and damping materials, which can absorb and attenuate the vibration from the lifting system or the lathe itself during the lifting of the lathe. During the lifting process, the shock absorber 72 can be elastically compressed and expanded, absorbing the vibration and converting it into heat energy or other forms of energy, thereby reducing the propagation of vibration to other structural components. The shock absorber 72 can also absorb the impact force generated by uneven load and machining process, reducing the influence of vibration on the accuracy of the CNC lathe. The support plate 73 is located between the top of the four shock absorbers 72, which is used to support the entire CNC lathe. The role of the support plate 73 is to convert the vibration energy absorbed by the shock absorber 72 into stable support force, ensuring that the CNC lathe can maintain stability during the lifting process, and will not vibrate or deviate violently when under stress. The support plate 73 also ensures the balance between the CNC lathe and the shock absorber 72, maintaining the stability and level of the bottom of the lathe during the operation of the machine tool. During the lifting process of the CNC lathe, the shock absorber 72 is mainly responsible for absorbing and isolating the vibration generated by the lifting action. When the lifting device starts, the lathe may encounter vibration due to friction, driving force or load change, and the shock absorber 72 reduces the influence of these vibrations on the structure of the lathe through its elasticity and damping effect. Through the cooperation of the fixing plate 71 and the support plate 73, the shock absorber 72 can effectively convert these absorbed vibration energy into heat or dissipate through other mechanisms, avoiding the continuous transmission of vibration to other components, ensuring the stable operation of the lathe. The shock absorber 72 effectively reduces the vibration during the lifting process and the operation of the machine tool, avoiding the machining errors and performance degradation caused by vibration, ensuring that the lathe is in a high-precision state during the entire working process. Due to the effective absorption and isolation of vibration, the machining accuracy of the CNC lathe is guaranteed, especially when high-precision machining is performed, the role of the shock absorbing mechanism 7 is particularly important. The shock absorber 72 can reduce the mechanical wear caused by vibration and impact on the lifting device and the lathe itself, thereby prolonging the service life of the equipment and reducing the maintenance and repair costs. Due to the reduction of vibration, the operator can feel a more stable working environment, reducing the interference of vibration on the operation, improving the comfort and safety of the lathe operation.
