[0013] 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.

[0014] Please see Figure 1-5 This utility model provides a technical solution: an intelligent high-precision CNC cradle-type turntable bearing, including a support frame 1, a servo motor 2 inside the support frame 1, and an output shaft on one side of the servo motor 2. A cradle platform 3 is located at one end of the output shaft, and a bearing assembly is placed on top of the cradle platform 3. A protective cover 4 is fitted over the bearing assembly, and the protective cover 4 has heat dissipation fins on its outer wall. Multiple sets of first bolts 5 are spirally screwed onto the lower outer side of the protective cover 4, and the other end of each first bolt 5 is spirally screwed into the cradle platform 3. It should be noted that a temperature sensor is correspondingly installed on the bearing seat, and the device is wirelessly connected to an external display system and control system to monitor the bearing temperature in real time during operation. Furthermore, the protective cover 4 is connected to the cradle platform 3 by multiple sets of first bolts 5 to form a spiral locking structure. Thus, the spirally installed protective cover 4 can protect the entire internal bearing assembly, while the heat dissipation fins on the outer wall of the protective cover 4 ensure the overall heat dissipation effect of the bearing.

[0015] The protective cover 4 has multiple sets of reinforcing ribs inside, and an acceleration sensor 6 is correspondingly provided on the outside of the reinforcing ribs. The acceleration sensor 6 has a second bolt 8 screwed on both sides, and a fixing cover 7 is screwed on the outside of the acceleration sensor 6 on the reinforcing rib. It should be noted that a layer of silicone grease can be applied between the mounting surfaces of the acceleration sensor 6 in this device to improve the transmission of high-frequency oscillations and prevent fretting corrosion, so as to ensure the service life of the acceleration sensor 6.

[0016] Furthermore, the accelerometer 6 is connected to the protective cover 4 by multiple sets of second bolts 8 to form a spiral locking structure, and the fixing cover 7 is threaded on its outer wall. The fixing cover 7, the protective cover 4, and the reinforcing ribs also form a spiral locking structure. Thus, the accelerometer 6 installed by the spiral can effectively monitor the external impact force on the protective cover 4, thereby facilitating the protection effect of the protective cover 4 assembly on the bearing as a whole.

[0017] The protective cover 4 has multiple mounting brackets 9 on its inner side, and each mounting bracket 9 has a buffer pad 10 inside. A base is placed on the lower end of the buffer pad 10, and multiple sets of third bolts 14 are screwed onto the base and buffer pad 10. A sliding groove is formed on the base, and a locking groove is formed at the top of the sliding groove. A limit block 11 is inserted into the sliding groove, and limit plates are respectively provided on both sides of the top of the limit block 11. The limit plates engage with the locking groove. A magnetic block 12 is embedded in the upper end of the limit block 11, and a magnetic block 12 is also embedded in the top of the sliding groove and on the base. A noise detector 13 is provided at the lower end of the limit block 11. It should be noted that each set of electrical components in this device is positioned according to its usage instructions during installation, and corresponding structures such as heat dissipation, vibration reduction, and control systems are provided to ensure… Each group of electrical components can operate according to a predetermined program. Furthermore, multiple sensors and detectors in the device are wirelessly connected to an external display system, facilitating real-time monitoring of the overall bearing assembly's performance. This invention is an intelligent, high-precision CNC cradle-type turntable bearing. All components are standard parts or components known to those skilled in the art. Their structure and principles can be understood by those skilled in the art through technical manuals or conventional experimental methods. All electrical components mentioned above refer to power elements, electrical components, and compatible monitoring computers and power supplies connected via wires. Specific connection methods should refer to the working principle described above, where the electrical connections between each component are completed in sequence. The detailed connection methods are well-known technologies in this field.

[0018] Furthermore, the buffer pad 10 forms a spiral locking structure with the base through multiple sets of third bolts 14, and the base forms an elastic buffer structure with the mounting bracket 9 through the buffer pad 10. Thus, the spiral mounting base facilitates the installation of the subsequent noise detector 13. At the same time, the buffer pad 10 can effectively reduce the impact of the vibration generated by the protective cover 4 itself on the noise detector 13.

[0019] Furthermore, the noise detector 13 forms a locking and limiting structure with the base through the limiting block 11, and the limiting block 11 forms a magnetic attraction structure with the base through multiple sets of magnetic attraction blocks 12. Thus, the magnetic attraction and locking components effectively ensure the installation stability of the noise detector 13, while the magnetic attraction installation avoids vibration caused by rigid connection, thus improving the accuracy of its detection data.

[0020] Working Principle: Using an intelligent high-precision CNC cradle-type rotary table bearing, the base is first screwed onto the mounting bracket 9 inside the protective cover 4 using multiple sets of third bolts 14. The limiting block 11 and limiting plate are then inserted into the grooves on the base. After the limiting block 11 is inserted, it can be rotated to engage the limiting plate in the engaging slot at the top of the groove. This engagement, along with the multiple sets of magnetic blocks 12, effectively ensures that the noise detector 13 can be stably installed on the mounting bracket 9. After the noise detector 13 is installed, the acceleration sensor 6 can be placed outside the corresponding reinforcing rib of the protective cover 4 and screwed onto it using multiple sets of second bolts 8. After the acceleration sensor 6 is installed, the fixing cover 7 can be screwed onto its outside to protect the acceleration sensor 6. Finally, the protective cover 4, which houses multiple sensors and detectors, can be placed outside the bearing assembly. The protective cover 4 protects and monitors the entire bearing, while the heat dissipation fins on the outer wall of the protective cover 4 effectively ensure the heat dissipation of the bearing during operation. During the operation of the cradle-type rotary table bearing, the controller drives the various electrical components in the device to work, and the control system makes them work according to a predetermined program. The cradle 3 reciprocates under the action of the servo motor 2, thereby driving the entire rotary table bearing to move, so as to perform CNC machining on the cradle-type rotary table bearing. At the same time, the detection data of the acceleration sensor 6 and the noise detector 13 can be viewed through the wirelessly connected display device, so as to effectively grasp the impact force of the external impact on the protective cover 4 and the noise generated by the overall operation of the bearing, thereby facilitating the timely detection of bearing operation problems and increasing the overall operating safety of the device. This is the usage process of the intelligent high-precision CNC cradle-type rotary table bearing.

[0021] Although the present invention 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 invention should be included within the protection scope of the present invention.
