[0002] Insulators are installed between conductors at different potentials, or between a conductor and a grounded structure. They withstand voltage and mechanical stress and are widely used in the power sector. Composite insulators, also known as synthetic insulators, consist of a glass fiber resin core rod, a silicone rubber sheath, and sheds. They are characterized by their light weight, high tensile strength, and excellent resistance to pollution flashover. They are widely used as external live conductors in overhead transmission lines, busbars in power plants and substations, and various electrical equipment.

Due to the varying internal bore sizes of these end fittings, excess sheath must be removed from both ends of the composite insulator before assembly. Traditionally, composite insulator sheath removal is done manually, which is labor-intensive, inefficient, and prone to uneven sheath end faces and lengths. Utility Model Content

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."
[0033] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0034] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0035] Example, see Figure 1、 Figure 2 and Figure 3 , which is an embodiment of the utility model, proposes a composite insulator sheath cutting system, including an operating table 1, a positioning seat 2, a first telescopic mechanism 3, and a cutting knife 4. The positioning seat 2 is arranged on the operating table 1, and the positioning seat 2 has a socket 5 and a knife groove 6. The axis of the socket 5 is arranged horizontally for inserting the end to be cut of the insulator. The knife groove 6 is located on one side of the socket 5 and is connected to the socket 5; the first telescopic mechanism 3 is arranged on the operating table 1 and is located outside the knife groove 6; one end of the cutting knife 4 is inserted in the knife groove 6, and the other end of the cutting knife 4 is connected to the movable end of the first telescopic mechanism 3. After the first telescopic mechanism 3 is extended, the cutting knife 4 enters the socket 5 for cutting the sheath of the insulator.
[0036] In this embodiment, taking the case where the axis of the socket 5 is horizontally arranged along the left-right direction and the first telescopic mechanism 3 is located in front of the positioning seat 2 as an example, the knife groove 6 is located in front of the socket 5. When in use, the end of the insulator to be cut is inserted into the socket 5 of the positioning seat 2, and then the first telescopic mechanism 3 is extended to push the cutting knife 4 to move backward into the socket 5 and penetrate the sheath of the insulator. The insulator is rotated, and the cutting knife 4 will cut the sheath of the insulator. After the cutting is completed, the insulator and the cut sheath are removed from the positioning seat 2, and the end of the next insulator to be cut is inserted into the socket 5 of the positioning seat 2. The operator only needs to rotate the insulator, which can reduce labor intensity and improve production efficiency. Through the cooperation of the positioning seat 2, the cutting knife 4 and the first telescopic mechanism 3, the axial displacement of the insulator during the cutting process can be avoided, the accuracy of the cutting position can be ensured, and the end face of the sheath is neat and the length and size are consistent. In order to avoid friction between the telescopic end of the first telescopic mechanism 3 and the positioning seat 2 during movement, the diameter of the knife groove 6 is larger than the diameter of the telescopic end of the first telescopic mechanism 3, so that a gap is left between the telescopic end of the first telescopic mechanism 3 and the positioning seat 2.
[0037] Furthermore, if Figure 1As shown, the apparatus further includes a second telescopic mechanism 7, which is disposed on the operating table 1 and outside the insertion hole 5. The second telescopic mechanism 7 is coaxially disposed with the insertion hole 5, and the sheath to be cut is located between the cutting blade 4 and the second telescopic mechanism 7. The end face of the core rod of the insulator inserted into the insertion hole 5 is designed to contact the movable end of the second telescopic mechanism 7. When the second telescopic mechanism 7 is extended, it pushes the core rod of the insulator to separate the core rod from the cut sheath. When the second telescopic mechanism 7 is extended and the movable end of the second telescopic mechanism 7 reaches a specified position, the insulator is inserted from left to right into the insertion hole 5 on the positioning seat 2. The right end face of the core rod of the insulator contacts the movable end (i.e., the left end) of the second telescopic mechanism 7. The second telescopic mechanism 7 supports and positions the insulator, more effectively preventing the insulator from swaying left and right during rotation, ensuring the accuracy of the cutting position, and ensuring that the end faces of the sheath are neat and consistent in length. After the cutting is completed, the second telescopic mechanism 7 is extended to push the core rod of the insulator. Under the obstruction of the cutting knife 4, the core rod moves to the left, and the cut sheath remains on the right side of the cutting knife 4, so that the core rod is separated from the cut sheath. The mechanized operation saves time and effort.
[0038] Furthermore, if Figure 1 and Figure 4 As shown, the apparatus further includes a feed stroke switch 8, a retract stroke switch 9, and a control module 10. The feed stroke switch 8 is disposed on the operating table 1 and is located between the fixed end of the first telescopic mechanism 3 and the positioning seat 2. It is used to detect the extension limit position of the movable end of the first telescopic mechanism 3. The retract stroke switch 9 is disposed on the operating table 1 and is located between the fixed end of the first telescopic mechanism 3 and the feed stroke switch 8. It is used to detect the retraction limit position of the movable end of the first telescopic mechanism 3. Both the feed stroke switch 8 and the retract stroke switch 9 are electrically connected to the control module 10, which is in turn electrically connected to the first telescopic mechanism 3. When the first telescopic mechanism 3 extends, pushing the cutting blade 4 backward, triggering the feed stroke switch 8, the control module 10 stops extending the first telescopic mechanism 3, and the cutting blade 4 reaches the designated position. The insulator can then be rotated to cut the insulator sheath. After the cutting is completed, the sheath is first separated from the core rod of the insulator, and then the first telescopic mechanism 3 is retracted, driving the cutting knife 4 to move forward. After the retraction stroke switch 9 is triggered, the control module 10 stops the retraction of the first telescopic mechanism 3 and the cutting knife 4 returns to its initial position. The advance position and retraction position of the cutting knife 4 can be accurately controlled.
[0039] Furthermore, if Figure 1 and Figure 4As shown, the second telescopic mechanism 7 further includes an ejection travel switch 11 and a reset travel switch 12. The ejection travel switch 11 is disposed on the operating platform 1 between the fixed end of the second telescopic mechanism 7 and the positioning seat 2, and is used to detect the extension limit position of the movable end of the second telescopic mechanism 7. The reset travel switch 12 is disposed on the operating platform 1 between the fixed end of the second telescopic mechanism 7 and the ejection travel switch 11, and is used to detect the retraction limit position of the movable end of the second telescopic mechanism 7. Both the ejection travel switch 11 and the reset travel switch 12 are electrically connected to the control module 10, which is electrically connected to the second telescopic mechanism 7. When the second telescopic mechanism 7 extends, its movable end moves to the left. When the ejection travel switch 11 is triggered, the control module 10 stops extending the second telescopic mechanism 7, and the movable end of the second telescopic mechanism 7 reaches the specified position. When the second telescopic mechanism 7 retracts, its movable end moves to the right. When the reset travel switch 12 is triggered, the control module 10 stops retracting the second telescopic mechanism 7 and returns it to its initial position. This allows for accurate control of the ejection position and reset position of the second telescopic mechanism 7.
[0040] Further, if Figure 1 As shown, it also includes a mounting base 13, which is arranged on the operating table 1, and the feed stroke switch 8 and the retract stroke switch 9 are both arranged on the mounting base 13. The feed stroke switch 8 and the retract stroke switch 9 are both integrated on the same mounting base 13 for easy disassembly and assembly.
[0041] Further, if Figure 1 As shown, both the feed stroke switch 8 and the retract stroke switch 9 are roller-type stroke switches, and further include a first trigger member 14. One end of the first trigger member 14 is disposed on the movable end of the first telescopic mechanism 3, and the other end of the first trigger member 14 is located between the rollers of the feed stroke switch 8 and the retract stroke switch 9. When the first telescopic mechanism 3 extends, the cutting knife 4 and the first trigger member 14 move backward. After the first trigger member 14 contacts the roller of the feed stroke switch 8, the feed stroke switch 8 is triggered. The control module 10 stops the extension of the first telescopic mechanism 3, and the cutting knife 4 reaches the designated position. When the first telescopic mechanism 3 contracts, the cutting knife 4 and the first trigger member 14 move forward. After the first trigger member 14 contacts the roller of the retract stroke switch 9, the retract stroke switch 9 is triggered. The control module 10 stops the contraction of the first telescopic mechanism 3, and the cutting knife 4 and the first trigger member 14 return to their initial positions. The structure is simple and easy to use.
[0042] Further, if Figure 1As shown, the ejection travel switch 11 and the reset travel switch 12 are both roller travel switches, and further include a second trigger member 15. The second trigger member 15 is arranged on the movable end of the second telescopic mechanism 7 and is located between the roller of the ejection travel switch 11 and the roller of the reset travel switch 12. When the second telescopic mechanism 7 extends, the second trigger member 15 moves to the left. After the second trigger member 15 contacts the roller of the ejection travel switch 11, the ejection travel switch 11 is triggered, and the control module 10 stops the extension of the second telescopic mechanism 7. When the second telescopic mechanism 7 contracts, the second trigger member 15 moves to the right. After the second trigger member 15 contacts the roller of the reset travel switch 12, the reset travel switch 12 is triggered, and the control module 10 stops the contraction of the second telescopic mechanism 7 and returns to the initial position. The structure is simple and easy to use.
[0043] Further, if Figure 1 As shown, the second telescopic mechanism 7 further includes a positioning plate 16, which is disposed on the periphery of the movable end of the second telescopic mechanism 7. The positioning plate 16 has a mounting hole, and the second trigger member 15 is inserted into the mounting hole and is detachably connected to the positioning plate 16. The length direction of the second trigger member 15 is the same as the length direction of the second telescopic mechanism 7. By replacing the second trigger member 15 with different lengths, the telescopic range of the second telescopic mechanism 7 can be changed to better meet usage requirements.
[0044] Further, if Figure 1 As shown, the second trigger member 15 is a bolt and also includes a locking nut 17, which is threadedly connected to the second trigger member 15. The positioning plate 16 is clamped between the nut of the second trigger member 15 and the locking nut 17. The locking nut 17 is threadedly connected to the second trigger member 15 to lock the second trigger member 15 to the positioning plate 16, providing a secure and reliable connection, and convenient and quick assembly and disassembly, saving time and effort.
[0045] Further, if Figure 1 As shown, the second telescopic mechanism 7 further includes a support base 18, which is disposed on the operating table 1 and located between the positioning plate 16 and the positioning base 2. The support base 18 has a guide hole, and the movable end of the second telescopic mechanism 7 is inserted into the guide hole to form a sliding fit. The support base 18 can support and guide the movable end of the second telescopic mechanism 7, thereby improving the stability of the second telescopic mechanism 7 during the telescopic process.
