[0002] The flattening of cable core joints plays a crucial role in cable manufacturing and repair. Its main purpose is to ensure the quality of cable connection points, thereby guaranteeing electrical performance, extending service life, and improving safety.

[0003] When workers are smoothing the core joints of thick cables, they often face a series of challenges and difficulties. These problems make the process extremely complex and laborious. First, due to their large diameter and weight, thick cables are relatively cumbersome to handle and are not as easy to maneuver as thin cables. This places higher demands on the operator's technical skills and physical strength. Second, in the subsequent polishing steps, in order to make the joint surface smooth and burr-free, powerful and efficient electric polishing tools must be used to overcome the additional resistance brought by the thick cables.

[0004] Therefore, it is necessary to design a cable core joint flattening device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the difficulty for workers to flatten the core joints of thick cables, the technical problem of this utility model is to provide a cable core joint flattening device.

[0006] A cable core joint flattening device includes a base plate, support frames, a first limiting block, a second limiting block, a first connecting block, a locking block, a torsion spring, a second connecting block, a clamping block, a screw, a torsion block, an arc-shaped arm, a motor, a grinding disc, a handle, and a start button. Support frames are fixedly connected to both sides of the base plate. A first limiting block is slidably connected to the top of each support frame. A second limiting block is rotatably connected to the top of each first limiting block. A first connecting block is fixedly connected to the front of each second limiting block.

Each of the corresponding locking blocks is connected by a torsion spring. A second connecting block is fixedly connected to the front side of each first limiting block. Each second connecting block engages with the corresponding locking block. A pressing block is slidably connected to the top of each second limiting block. A screw is rotatably connected to the top of each pressing block. A torsion block is fixedly connected to the top of each screw. An arc-shaped arm is rotatably connected to the top of the base plate. A motor is fixedly connected to the top of the arc-shaped arm. A grinding disc is fixedly connected to the output shaft of the motor. A handle is fixedly connected to the front side of the top of the arc-shaped arm. A start button is provided at the rear of the handle. The start button is electrically connected to the motor.

[0007] To further explain, it also includes a circular saw and a third limiting block. The circular saw is fixedly connected to the grinding disc, and the third limiting block is fixedly connected to the upper part of the base plate.

[0008] Further explanation: It also includes a lower pressure plate, a first spring, an abutment block, a second spring, and a connecting plate. The lower pressure plate is fixedly connected to the lower part of the arc-shaped arm. Each first limit block is connected to a first spring between itself and its corresponding support frame.

[0013] 2. This utility model, through the linkage structure between the arc arm, the lower pressure plate, the connecting plate and the abutment block, ensures that the cross-section of the cable is always in close contact with the grinding disc during the grinding process when the arc arm rotates and presses down.

Detailed Implementation

[0021] Example: A cable core joint flattening treatment device, such as... Figures 1-5 As shown, the device includes a base plate 1, a support frame 2, a first limiting block 3, a second limiting block 4, a first connecting block 5, a locking block 6, a torsion spring 7, a second connecting block 8, a clamping block 9, a screw 10, a torsion block 11, an arc arm 12, a motor 13, a grinding disc 14, a handle 15, and a start button 16. The base plate 1 has support frames 2 symmetrically welded to its top. Each support frame 2 has a first limiting block 3 slidably connected to its top. Each first limiting block 3 has a second limiting block 4 rotatably connected to its rear top. Each second limiting block 4 has a first connecting block 5 bolted to its front. Each first connecting block 5 has a locking block 6 rotatably connected to its front. Two torsion springs 7 are connected between each first connecting block 5 and its corresponding locking block 6. The two torsion springs 7 are symmetrically arranged. Each limiting block 3 has a second connecting block 8 bolted to its front side. Each second connecting block 8 engages with a corresponding locking block 6. Each second limiting block 4 has a sliding clamping block 9 slidably connected to its top. The bottom of the clamping block 9 is curved to fit the cable. Each clamping block 9 has a screw 10 rotatably connected to its top. Each screw 10 has a torsion block 11 fixedly connected to its top. The bottom rear side of the base plate 1 has an arc-shaped arm 12 rotatably connected to its top rear side. The top front side of the arc-shaped arm 12 is bolted to a motor 13. The output shaft of the motor 13 is connected to a grinding disc 14 via a coupling. The grinding disc 14 is made of silicon carbide. A handle 15 is welded to the top front side of the arc-shaped arm 12. A start button 16 is located on the lower rear side of the handle 15. The start button 16 is electrically connected to the motor 13.

[0022] like Figure 1 and Figure 4As shown, it also includes a circular saw 17 and a third limiting block 18. The circular saw 17 is welded onto the grinding disc 14, and the third limiting block 18 is welded onto the upper rear side of the base plate 1.

[0023] This equipment can be used when it is necessary to flatten the cable core. First, the operator passes the cable between the first limiting block 3 and the second limiting block 4, so that the end of the cable to be ground is directly below the grinding disc 14. Then, the operator rotates the torsion block 11 clockwise, causing the screw 10 to rotate and move downwards synchronously. The clamping block 9, which is rotatably connected to the screw 10, will also move downwards synchronously. The clamping block 9 and the first limiting block 3 work together to clamp and fix the cable. The arc-shaped clamping block 9 can fit tightly against the cable. Then, the operator holds the handle 15 and presses it down clockwise, so that the grinding disc 14 comes into contact with the cable core. Then, the operator presses the start button 16, and the motor 13 starts to drive the grinding disc 14 to rotate and grind the cable core to make it flat. Finally, the operator rotates the torsion block 11 counterclockwise to disengage the clamping block 9 from the cable and pulls out the cable. When it is necessary to cut the middle of the cable and then level it, if the cable is too long to pass between the first limiting block 3 and the second limiting block 4, the clamping block 6 can be used. Pressing down the top causes the locking block 6 to rotate counterclockwise, deforming the torsion spring 7 and disengaging the lower part of the locking block 6 from the second connecting block 8. Then, the second limiting block 4 is opened counterclockwise, releasing the locking block 6. The locking block 6 will reset under the action of the torsion spring 7, which then returns to its original position. The cable is then inserted, and the second limiting block 4 is lowered clockwise. Because the upper part of the second connecting block 8 has an inclined surface, the locking block 6 will automatically re-engage with the second connecting block 8. The torsion spring 7 prevents the locking block 6 from accidentally disengaging from the second connecting block 8. To secure the cable, rotate the torsion block 11 clockwise. Then, the operator holds the handle 15 and presses it down clockwise. The circular saw 17 will cut the cable. Continue pressing down, and the grinding disc 14 will grind the cable core. After grinding, reopen the second limit block 4 to remove the cable. The circular saw 17, made of silicon carbide, is more robust and durable. The third limit block 18 provides a fulcrum when the arc arm 12 is raised, allowing the arc arm 12 to remain raised, which facilitates cable securing.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a lower pressure plate 19, a first spring 20, an abutment block 21, a second spring 22, and a connecting plate 23. The lower pressure plate 19 is welded to the lower front side of the arc-shaped arm 12. Each first limiting block 3 is connected to the corresponding support frame 2 with two first springs 20. The two first springs 20 are symmetrical front and back, and each first spring is in a compressed state. The abutment block 21 is symmetrically slidably connected to the rear side of the first spring support frame 2. Each abutment block 21 is connected to the rear side of the corresponding support frame 2 with a second spring 22. The connecting plate 23 is welded between the bottoms of the two abutment blocks 21, and the connecting plate 23 abuts against the lower pressure plate 19.

[0025] like Figure 1 and Figure 5 As shown, it also includes a protective button 24 and a protective cover 25. The protective button 24 is provided on the upper rear side of the handle 15. The protective button 24 is electrically connected to the motor 13. The protective cover 25 is bolted to the top left side of the arc arm 12. The protective cover 25 covers the outside of the grinding disc 14.

[0026] When the arc arm 12 rotates clockwise, the lower pressure plate 19 will press the connecting plate 23 downward, and the abutment block 21 will move down together. The abutment block 21 will disengage from the first limit block 3, and the first spring 20 will give the first limit block 3 a rightward elastic force, so that the cross-section of the cable is tightly attached to the grinding disc 14. Even if the cable core is shortened due to grinding, the cross-section of the cable is still attached to the grinding disc 14, ensuring that the grinding surface can be ground in place. The protective cover 25 can effectively prevent the circular saw 17 from causing injury to personnel in case of accident, and play a safety protection role. When starting the motor 13, the start button 16 and the protection button 24 need to be pressed at the same time to prevent the staff from accidentally starting the motor 13 due to accidentally touching the start button 16, causing the circular saw 17 to injure people.
