These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a rotating shaft device for repairing porcelain insulator blanks is provided.

[0019] Example 1 like Figure 1-4As shown, a ceramic insulator blank-repairing rotating shaft device according to an embodiment of the present invention includes a back plate 1, an upper pressure plate 2, and a lower pressure plate 3. The upper pressure plate 2 is disposed above the front side of the back plate 1, and the lower pressure plate 3 is disposed below the front side of the back plate 1. Positioning seats 4 are fixedly connected to the top of the upper pressure plate 2 and the bottom of the lower pressure plate 3, respectively. An upper clamping plate 5 is connected to the bottom of the upper pressure plate 2, and a lower bearing plate 6 is connected to the top of the lower pressure plate 3. A first servo motor 7 is fixedly connected to the top side of the back plate 1. An installation port 8 is provided through the front side of the back plate 1. A positive and negative threaded screw 9 is connected to the bottom side of the inner wall of the installation port 8 through a bearing. Guide rods 10 are provided on both sides of the positive and negative threaded screw 9. The output shaft of the first servo motor 7 is fixedly connected to the top of the positive and negative threaded screw 9. Moving blocks 11 are symmetrically sleeved on the outer sides of the positive and negative threaded screw 9 and the guide rods 10. The front side of the moving blocks 11 is fixedly connected to the rear side of the upper pressure plate 2 and the lower pressure plate 3, respectively. The moving block 11 is equipped with a lead screw nut inside, and the moving block 11 is connected to the upper and lower ends of the outer wall of the positive and negative thread lead screw 9 through the lead screw nut. When the control system issues a command, the first servo motor 7 starts and rotates in a specific direction. The motor drives the positive and negative thread lead screw 9 to rotate clockwise synchronously. Since the nut of the upper moving block 11 is positive thread, the clockwise rotation of the lead screw will drive it to move downward. Since the nut of the lower moving block 11 is negative thread, the clockwise rotation of the lead screw will drive it to move upward. Under the constraint of the guide rod 10, the two moving blocks 11 move synchronously towards the center. They drive the upper pressure plate 2 to move downward and the lower pressure plate 3 to move upward, thereby firmly clamping the porcelain insulator blank placed in the middle through the upper clamping plate 5 and the lower bearing plate 6. This achieves the absolute synchronous movement of the upper and lower clamping mechanisms, ensuring that the clamping force is evenly applied to the upper and lower ends of the blank and avoiding eccentric loading.

[0020] Example 2 like Figure 1-4As shown, a ceramic insulator blank trimming rotating shaft device according to an embodiment of the present invention includes a back plate 1, an upper pressure plate 2, and a lower pressure plate 3. The upper pressure plate 2 is disposed above the front side of the back plate 1, and the lower pressure plate 3 is disposed below the front side of the back plate 1. Positioning seats 4 are fixedly connected to the top of the upper pressure plate 2 and the bottom of the lower pressure plate 3, respectively. An upper clamping plate 5 is connected to the bottom of the upper pressure plate 2, and a lower bearing plate 6 is connected to the top of the lower pressure plate 3. The positioning seat 4 includes a mounting frame 12 and a telescopic cylinder 13. The top of the mounting frame 12 is fixedly connected to the telescopic cylinder 13, and the mounting frame 12 contains... A movable column 14 is provided through the bottom side of the wall. The movable column 14 passes through the outer side of the mounting frame 12, the upper pressure plate 2, and the lower pressure plate 3 in sequence, and is fixedly connected to the positioning seat 4 respectively. The movable end of the telescopic cylinder 13 extends into the mounting frame 12 and is fixedly connected to a metal ball 15. A detection seat 16 is connected to the top of the movable column 14. The metal ball 15 movably abuts against the top of the detection seat 16. The detection seat 16 includes a pressure sensor 17 and an electromagnet 18. The top of the pressure sensor 17 is fixedly connected to the electromagnet 18. The electromagnet 18 and the metal ball 15 are magnetically attracted. With the attachment fixed, when the upper and lower clamping plates are about to contact the billet, the system issues a command, the electromagnet 18 is energized, generating a strong magnetic force that firmly attracts and fixes the metal ball 15 to the surface of the electromagnet 18. The telescopic cylinder 13 continues to apply thrust. Since the metal ball 15 and the detection seat 16 are now integrated by magnetic force, the thrust of the cylinder acts entirely on the pressure sensor 17 through this connection. The pressure sensor 17 monitors this force in real time and feeds the data back to the control system. The control system dynamically adjusts the telescopic cylinder according to the preset clamping force value. The output pressure of 13 ensures that the actual clamping force is stable within the set range, clamping firmly without crushing the blank. Since the connection point is a metal ball 15, which is a spherical movable connection, if the upper and lower end faces of the blank are not parallel, causing the clamping plate to tilt under force, this ball hinge structure can undergo a slight angular deflection, ensuring that the clamping force acts perpendicularly on the clamping plate, avoiding bending moment caused by off-center loading, protecting the blank and the equipment, and realizing real-time and accurate monitoring and feedback control of the clamping force, fundamentally solving the problem of easy damage to ceramic blanks.

[0021] Example 3 like Figure 1-4As shown, a ceramic insulator blank trimming rotating shaft device according to an embodiment of the present invention includes a back plate 1, an upper pressure plate 2, and a lower pressure plate 3. The upper pressure plate 2 is disposed above the front side of the back plate 1, and the lower pressure plate 3 is disposed below the front side of the back plate 1. Positioning seats 4 are fixedly connected to the top of the upper pressure plate 2 and the bottom of the lower pressure plate 3, respectively. An upper clamping plate 5 is connected to the bottom of the upper pressure plate 2, and a lower bearing plate 6 is connected to the top of the lower pressure plate 3. Both the upper clamping plate 5 and the lower bearing plate 6 include a mounting cover 19 and a rotating disk 20. The rotating disk 20 is embedded in the inner wall of the mounting cover 19 through bearings, and a second servo motor 21 is fixedly connected to the top side of the inner wall of the mounting cover 19. The output shaft of machine 21 is fixedly connected to the rotating disk 20. When the blank is clamped by the upper and lower pressure plates, the control system simultaneously sends drive signals to the upper clamping plate 5 and the second servo motor 21 and the second servo motor 21 of the lower bearing plate 6. The two second servo motors 21 start to rotate synchronously, and their output shafts directly drive the rotating disk 20 to rotate. The porcelain insulator blank fixed between the upper and lower rotating disks 20 begins to rotate smoothly and accurately under the joint drive of the friction force at both ends. At this time, the operator can perform blank trimming operations on the rotating blank. The synchronous drive from the upper and lower ends ensures that the rotational force is transmitted evenly, which greatly improves the rotational stability and processing accuracy.

[0022] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the control system issues a command, the first servo motor 7 starts and rotates in a specific direction. The motor drives the positive and negative thread screws 9 to rotate clockwise synchronously. Since the nut of the upper moving block 11 is positive thread, the clockwise rotation of the screw will drive it to move downward. Since the nut of the lower moving block 11 is negative thread, the clockwise rotation of the screw will drive it to move upward. Under the constraint of the guide rod 10, the two moving blocks 11 move synchronously towards the center. They drive the upper pressure plate 2 to move downward and the lower pressure plate 3 to move upward, thereby firmly clamping the porcelain insulator blank placed in the middle through the upper clamping plate 5 and the lower bearing plate 6. When the upper and lower clamping plates are about to contact the blank, the system issues a command, the electromagnet 18 is energized, generating a strong magnetic force, which firmly attracts and fixes the metal ball 15 to the surface of the electromagnet 18. The telescopic cylinder 13 continues to apply thrust. Since the metal ball 15 and the detection seat 16 are now integrated by magnetic force, the thrust of the cylinder is fully applied to the pressure sensor 17 through this connection. The pressure sensor 17 monitors this force in real time and feeds the data back to the control system. The control system dynamically adjusts the output pressure of the telescopic cylinder 13 according to the preset clamping force value to ensure that the actual clamping force is stable within the set range, which is both firm and does not crush the blank. After the blank is clamped by the upper and lower pressure plates, the control system simultaneously sends drive signals to the upper clamping plate 5 and the second servo motor 21 and the lower bearing plate 6's second servo motor 21. The two second servo motors 21 start to rotate synchronously, and their output shafts directly drive the rotating disk 20 to rotate. The porcelain insulator blank fixed between the upper and lower rotating disks 20 begins to rotate smoothly and accurately under the combined drive of the frictional forces at both ends. At this time, the operator can perform blank trimming operations on the rotating blank.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
