Description

Technical Field

[0001] This utility model belongs to the technical field of coiling mechanism, specifically a wire stretching and fastening coiling mechanism. Background Technology

[0002] In some wire processing scenarios, it is often necessary to fold the ends of the wires in half and then loop them to expand their uses. For example, metal wire ropes need to be processed by a looping mechanism to optimize their subsequent use.

[0003] Currently, some existing coiling mechanisms use mechanical grippers to perform the coiling operation. After the mechanical grippers hold the steel wire, they rotate to form a coil at the head of the wire, stretching and twisting the wire to form a coil of a specific shape. The coil is then continuously formed by traction and movement.

[0004] During the actual operation of this coiling mechanism, significant friction will occur between the mechanical gripper and the steel wire due to relative motion. To ensure clamping stability, the mechanical gripper needs to be disassembled and maintained regularly. However, most existing mechanical grippers are installed and fixed with multiple sets of bolts. During disassembly, workers need to repeatedly rotate the bolts, which is cumbersome and results in low maintenance efficiency. Therefore, a wire stretching and fastening coiling mechanism is proposed to address the above problems. Utility Model Content

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-6This utility model provides a wire stretching, fastening, and coiling mechanism, including a processing support frame 1; a coiling driver 2 is mounted on the top of the processing support frame 1; a limiting shell 4 is fixedly connected to the end of the coiling driver 2; a gripper 3 is inserted into the inner wall of the limiting shell 4; a coiling shell 5 is fixedly connected to the end of the gripper 3; a through groove 47 is formed on the side wall of the limiting shell 4; a limiting plate 41 is slidably connected to the middle of the through groove 47; a limiting groove 31 is formed on the side wall of the gripper 3; the limiting plate 41 contacts the inner wall of the limiting groove 31; a rectangular groove 46 is formed on the side wall of the bottom of the limiting shell 4; a sliding shell 43 is slidably connected to the inner wall of the rectangular groove 46; a connecting plate 42 is fixedly connected to the end of the sliding shell 43; the connecting plate 42 is fixedly connected to the bottom of the limiting plate 41; a handle 45 is fixedly connected to the side wall of the connecting plate 42; during operation, when the gripper 3 needs to be disassembled for maintenance, the handle 45 can be pulled to move the connecting plate 42, which will then move the limiting plate 42. The plate 41 moves until the limiting plate 41 disengages from the inner wall of the limiting groove 31. This allows the gripper 3 to be pushed out of the middle of the limiting shell 4. Maintenance is complete. When installation is required, the gripper 3 is directly inserted into the inner wall of the limiting shell 4. During insertion, the gripper 3 pushes the limiting plate 41 along the inclined surface of the limiting plate 41. The limiting plate 41 drives the connecting plate 42 to move, and the connecting plate 42 drives the sliding shell 43 to move. The sliding shell 43 stretches the spring 44 until the limiting plate 41 overlaps with the limiting groove 31. At this time, the spring 44 will pull the sliding shell 43 back to its original position through its elasticity. The connecting plate 42 and the limiting plate 41 will also return to their original positions, allowing the limiting plate 41 to insert into the inner wall of the limiting groove 31 and limit the gripper 3. This eliminates the need for workers to use tools to rotate multiple sets of bolts when installing and removing the gripper 3, improving the efficiency of installation and removal. The maintenance efficiency of the gripper 3 is also improved, enhancing its practicality.

[0028] Furthermore, such as Figures 2-5As shown, a threaded rod 51 is rotatably connected to the top side of the end of the gripper 3; a slot 52 is provided at the top of the threaded rod 51; the outer wall of the threaded rod 51 is rotatably connected to the inner wall of the top of the coiling shell 5; a moving block 59 is threadedly connected to the outer wall of the threaded rod 51; a connecting plate 58 is hinged to the middle of the moving block 59; a rectangular plate 54 is slidably connected to the middle of the coiling shell 5; an extension plate 53 is fixedly connected to the end of the rectangular plate 54; a hinge block 57 is fixedly connected to the side wall of the extension plate 53; the top of the connecting plate 58 is rotatably connected to the middle of the hinge block 57; the inner wall of the slot 52 is hexagonal. During operation, when coiling the steel wire, it is necessary to ensure that the steel wire is in the middle of the gripper 3 and located inside the coiling shell 5. When the gripper 3 is rotated, the steel wire will naturally form a loop and fit around the outer wall of the forming shell 5. When different sizes of loops need to be processed, a tool can be inserted into the inner wall of the slot 52, and then the threaded rod 51 can be rotated. At this time, the moving block 59, which is threaded to the outer wall of the threaded rod 51, will move on the inner wall of the forming shell 5. The angle of the connecting plate 58 will change accordingly, and its bottom will rotate with the moving block 59, while its top will rotate with the hinge block 57. The hinge block 57 will drive the expansion plate 53 to move. In this way, the expanded expansion plate 53 will make the loop fitted on the outer wall of the forming shell 5 larger, eliminating the need to change grippers 3 of different sizes for processing, thus improving practicality.

[0029] Furthermore, such as Figure 3 and Figure 6 As shown, multiple sets of springs 44 are fixed to the inner wall of the sliding shell 43. The multiple sets of springs 44 are arranged in a linear array on the inner wall of the sliding shell 43. The other end of the spring 44 is fixed to the middle of the rectangular groove 46. When working, the spring 44 has a certain elasticity. Through its own elasticity, it can ensure that when the gripper 3 is installed on the inner wall of the limiting shell 4, the limiting plate 41 is always inserted into the inner wall of the limiting groove 31, thus ensuring the stability of the limiting. Setting multiple sets of springs 44 can further improve the stability of the limiting.

[0030] Furthermore, such as Figure 3 As shown, the top of the limiting plate 41 is set as an inclined surface. During operation, the inclined surface ensures that when installing the clamping claw 3, it is not necessary to move the limiting plate 41 by pulling the connecting plate 42, which improves the installation efficiency.

[0031] Furthermore, such as Figure 5 As shown, a groove 56 is provided on the top side of the middle part of the ring shell 5; a slider 55 is fixedly connected to the top of the rectangular plate 54; the slider 55 is slidably connected to the inner wall of the groove 56. During operation, the cooperation between the slider 55 and the groove 56 ensures that the expansion plate 53 can move horizontally and ensures the stability of its movement.

[0032] Furthermore, such as Figure 5 As shown, a rectangular strip 510 is fixedly connected to the middle of the ring shell 5; a through groove 511 is provided on the side wall of the movable block 59; the outer wall of the rectangular strip 510 is slidably connected to the inner wall of the through groove 511. During operation, the cooperation between the rectangular strip 510 and the through groove 511 ensures that the movable block 59 can only move horizontally up and down under the drive of the threaded rod 51. In addition, the threaded rod 51 and the movable block 59 have an axial self-locking characteristic, ensuring that the movable block 59 will not move when the threaded rod 51 is not rotated.

[0033] Furthermore, such as Figure 5 As shown, multiple sets of the expansion plate 53, hinge block 57, and connecting plate 58 are provided, and the multiple sets of expansion plates 53, hinge blocks 57, and connecting plates 58 are arranged in a circular array with the center of the ring shell 5 as the origin. During operation, by setting multiple sets of expansion plates 53, hinge blocks 57, and connecting plates 58, it is ensured that the wire rings of different sizes tend to be circular when they are processed.

[0034] Working principle: When the gripper 3 needs to be disassembled for maintenance, pull the handle 45 to move the connecting plate 42. The connecting plate 42 will then move the limiting plate 41 until the limiting plate 41 disengages from the inner wall of the limiting groove 31. This allows the gripper 3 to be pushed out of the middle of the limiting shell 4, completing the maintenance. When installation is needed, simply insert the gripper 3 into the inner wall of the limiting shell 4. During insertion, the gripper 3 will push the limiting plate 41 along its inclined surface, causing the limiting plate 41 to move. The limiting plate 41 will then move the connecting plate 42, connecting... Plate 42 will drive the sliding shell 43 to move, and the sliding shell 43 will stretch the spring 44 until the limiting plate 41 overlaps with the limiting groove 31. At this time, the spring 44 will pull the sliding shell 43 back to its original position through its own elasticity. The connecting plate 42 and the limiting plate 41 will also return to their original positions, so that the limiting plate 41 is inserted into the inner wall of the limiting groove 31 to limit the gripper 3. In this way, when installing and disassembling the gripper 3, workers do not need to use tools to rotate multiple sets of bolts, which improves the efficiency of disassembly and assembly. The maintenance efficiency of the gripper 3 is also improved, which enhances its practicality.

[0035] When making a loop with the steel wire, it is necessary to ensure that the steel wire is in the middle of the clamp 3 and inside the looping shell 5. When the clamp 3 is rotated, the steel wire will naturally form a loop and fit around the outer wall of the looping shell 5. When different sizes of loops need to be made, a tool can be inserted into the inner wall of the slot 52 and then the threaded rod 51 can be rotated. At this time, the moving block 59, which is threaded to the outer wall of the threaded rod 51, will move on the inner wall of the looping shell 5. The angle of the connecting plate 58 will change accordingly, and its bottom will rotate with the moving block 59, while its top will rotate with the hinge block 57. The hinge block 57 will drive the expansion plate 53 to move, thus expanding the loop on the outer wall of the looping shell 5. This eliminates the need to change the clamp 3 of different sizes for processing, improving practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
