Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for power cable termination heads. Background Technology

[0002] The power cable termination bending device is a specialized piece of equipment used in power construction to precisely bend and shape cable terminations. Driven by a stepper motor or other power source, it employs a pressure plate linkage mechanism and V-shaped wheels to apply pressure to the cable, achieving bending. This allows for precise angle control, adaptability to different cable specifications, and reduced insulation damage. Suitable for substations, distribution cabinets, and other similar applications, it offers higher precision, faster efficiency, and less damage compared to manual bending, improving construction standardization and reliability.

[0003] In existing technology, the device typically includes: a mounting platform, a drive motor, a bending column, a guide column, and a clamping block. One side of the bending column is rotatably connected to one side of the mounting platform, one side of the guide column is fixedly connected to one side of the mounting platform, the output end of the drive motor is fixedly connected to one side of the bending column, and the drive motor is fixedly installed inside the mounting platform. One side of the clamping block is fixedly connected to one side of the bending column, and the clamping block has two clamping claws inside. In use, the end of the power cable is passed through the guide column and the bending column, and one side of the end of the power cable is inserted into the clamping block. The two clamping claws clamp and fix the end of the power cable. Then, the drive motor is started, which drives the bending column to rotate, bending the cable. During the rotation of the column, the bending column drives the clamping block to rotate synchronously. The two clamping claws inside the clamping block cause one side of the power cable terminal to rotate around the outer wall of the bending column, so that the power cable terminal forms a certain angle, completing the bending of the power cable terminal. In practical use, the clamping block in the existing technology is usually only for clamping one type of power cable terminal. Different power cable terminals have different models and different thicknesses. The existing clamping block cannot clamp and fix thicker and thinner power cable terminals well, resulting in poor applicability of the device and difficulty in adapting to more different environments.

[0004] Therefore, it is necessary to provide a new power cable terminal bending device to solve the above-mentioned technical problems. Utility Model Content

[0007] The clamping device includes: a mounting block, a driving assembly, a mounting plate, two first sliding blocks, and two second sliding blocks.

Each of the two first sliding blocks and the two second sliding blocks has a clamping rod on the side away from the driving assembly. The four clamping rods pass through the four sliding grooves and are slidably connected to the four sliding grooves. Each of the four clamping rods has a clamping plate on the side that is relatively close to each other. All four clamping plates are arc-shaped.

[0008] Preferably, the drive assembly includes: two first threaded rods, two second threaded rods, and four bevel gears. A fixing block is fixedly connected to the center of the mounting plate.

The sides of the two first threaded rods and the two second threaded rods away from the fixing block are rotatably connected to the four sides of the mounting plate. One side of each of the four bevel gears is installed on the outside of the two first threaded rods and the two second threaded rods near the fixing block, and the four bevel gears mesh with each other. Two first sliding blocks are threadedly connected to the outside of the two first threaded rods, and two second sliding blocks are threadedly connected to the outside of the two second threaded rods. One of the two first threaded rods has its side away from the fixing block extending through the mounting block, and a driver is fixedly connected to the side of this first threaded rod away from the fixing block.

[0009] Preferably, the driver includes a fixing plate and a drive motor, one side of the fixing plate is fixedly connected to one side of the mounting block, one side of the drive motor is fixedly connected to one side of the fixing plate, and the output end of the drive motor is fixedly connected to the side of the first threaded rod away from the fixing block.

[0010] Preferably, the thread direction of the two first threaded rods is opposite to the thread direction of the two second threaded rods.

[0013] Compared with related technologies, the power cable terminal bending device provided by this utility model has the following advantages:

[0014] Beneficial effects:

[0015] In practical use, the power cable termination is passed through the bending device and inserted into the mounting block. The drive motor is then activated, rotating one of the two first threaded rods. During this rotation, the first threaded rod drives a connected bevel gear to rotate synchronously. Simultaneously, all four bevel gears rotate. While the four bevel gears rotate, the other first threaded rod and the two second threaded rods rotate. At this time, the two first sliding blocks and the two second sliding blocks move closer together along the four sliding grooves until the four clamping plates contact the outer side of the power cable termination. Since the four clamping plates are all arc-shaped, they clamp and fix the power cable termination. The bending device then continues to bend the power cable termination. During use, the four clamping plates can slide along the four sliding grooves, allowing adjustment of the distance between them to accommodate power cable terminations of different thicknesses. The arc shape of the four clamping plates ensures a more secure clamping and fixation of the power cable termination. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 — Figure 6 ,in, Figure 1 Schematic diagram of the overall structure of the power cable termination bending device provided by this utility model Figure 1 ; Figure 2 Schematic diagram of the overall structure of the power cable termination bending device provided by this utility model Figure 2 ; Figure 3 A partial structural schematic diagram of the power cable terminal bending device provided by this utility model; Figure 4 A schematic diagram of the clamping device structure of the power cable terminal bending device provided by this utility model; Figure 5 A schematic diagram of the clamping device structure of the power cable terminal bending device provided by this utility model; Figure 6 A schematic diagram of the internal structure of the clamping device of the power cable terminal bending device provided by this utility model.

[0025] In practical implementation, the power cable terminal bending device has the following structure: Figure 1 — Figure 6 As shown, the present invention includes: a power cable terminal bending device comprising: a bending device body and a clamping device, wherein one side of the clamping device is fixedly connected to one side of the bending device body;

[0026] The clamping device includes: a mounting block 1, a drive assembly, a mounting plate 2, two first sliding blocks 3, and two second sliding blocks 4. One side of the mounting plate 2 is fixedly connected to one side of the bending device body. The mounting plate 2 is fixedly installed inside the mounting block 1. The mounting plate 2 and the mounting block 1 are both provided with four sliding grooves 5. The drive assembly is rotatably installed inside the mounting plate 2. The two first sliding blocks 3 and the two second sliding blocks 4 are respectively threadedly connected to the outside of the drive assembly. The two first sliding blocks 3 and the two second sliding blocks 4 are each provided with a clamping rod 6 on the side away from the drive assembly. The four clamping rods 6 pass through the four sliding grooves 5 respectively. The four clamping rods 6 are slidably connected to the four sliding grooves 5 respectively. The four clamping plates 7 are provided on the side of the four clamping rods 6 that are relatively close to each other. The four clamping plates 7 are all arc-shaped.

[0027] It should be noted that in the use of the above device, when the drive motor 13 drives one of the first threaded rods 8 to rotate, the first threaded rod 8 and the other two second threaded rods 9 rotate synchronously through four bevel gears 10. At this time, the two first sliding blocks 3 and the two second sliding blocks 4 installed on the two first threaded rods 8 and the two second threaded rods 9 will move closer to each other, so that the two first sliding blocks 3 and the two second sliding blocks 4 can drive the four clamping rods 6 and the four clamping plates 7 to move closer to each other until the four clamping plates 7 clamp the cable terminal head. Since the four clamping plates 7 are all arc-shaped, there are more contact points between the four clamping plates 7 and the cable terminal head during use, so that the four clamping plates 7 can clamp the cable terminal head more stably. Moreover, the distance between the four clamping plates 7 is adjustable, so the four clamping plates 7 can be used to clamp more cable terminal heads of different thicknesses, making the device more adaptable and able to accommodate more different cable terminal heads.

[0028] The drive assembly includes two first threaded rods 8, two second threaded rods 9, and four bevel gears 10. A fixing block 11 is fixedly connected to the center of the mounting plate 2. One side of each of the two first threaded rods 8 and two second threaded rods 9 is rotatably connected to the outside of the fixing block 11, and the two first threaded rods 8 and two second threaded rods 9 are staggered. The side of each of the two first threaded rods 8 and two second threaded rods 9 away from the fixing block 11 is rotatably connected to the four sides of the interior of the mounting plate 2. One side of each of the four bevel gears 10 is installed on the outside of each of the two first threaded rods 8 and two second threaded rods 9 near the fixing block 11. The four bevel gears 10 mesh with each other. Two first sliding blocks 3 are threaded... Two first threaded rods 8 are connected to the outside of the two first threaded rods 9 respectively. Two second sliding blocks 4 are threadedly connected to the outside of the two second threaded rods 9. The side of one of the first threaded rods 8 away from the fixed block 11 passes through the mounting block 1. The side of the first threaded rod 8 away from the fixed block 11 is fixedly connected to a driver. The driver includes a fixed plate 12 and a drive motor 13. One side of the fixed plate 12 is fixedly connected to one side of the mounting block 1. One side of the drive motor 13 is fixedly connected to one side of the fixed plate 12. The output end of the drive motor 13 is fixedly connected to the side of the first threaded rod 8 away from the fixed block 11. The thread direction of the two first threaded rods 8 is opposite to the thread direction of the two second threaded rods 9.

[0029] It should be noted that the thread directions of the two first threaded rods 8 and the two second threaded rods 9 are opposite. In practical use, since the drive motor 13 can drive one of the first threaded rods 8 to rotate, and the two first threaded rods 8 and the other second threaded rod 9 are installed alternately, the two first threaded rods 8 and the two second threaded rods 9 are connected and driven by four bevel gears 10. At this time, when rotating, the rotation directions of the two first threaded rods 8 and the two second threaded rods 9 are opposite. The opposite thread direction design of the two first threaded rods 8 and the two second threaded rods 9 can ensure that the two first sliding blocks 3 and the two second sliding blocks 4 can move synchronously towards or away from each other, realizing the clamping and fixing function of the device. The drive motor 13 is specifically a TZ155X020 permanent magnet synchronous drive motor 13. This drive motor 13 drives one of the first threaded rods 8 to rotate. When the threaded rod 8 rotates, it drives one of the bevel gears 10 connected to it to rotate. Since all four bevel gears 10 are meshed, they can simultaneously drive the other first threaded rod 8 and the two second threaded rods 9 to rotate. When the two first threaded rods 8 and the two second threaded rods 9 rotate, the two first sliding blocks 3 and the two second sliding blocks 4 will move linearly on the two first threaded rods 8 and the two second threaded rods 9. By adjusting the rotation direction of the drive motor 13, the two first sliding blocks 3 and the two second sliding blocks 4 can be moved closer to each other or further away from each other. That is, the four clamping plates 7 can be adjusted to move further away from each other or closer to each other. The four clamping plates 7 can be adjusted according to the cable terminal heads of different thicknesses, making the device more adaptable and easier to use.

[0030] The bending device body includes: a mounting platform 14, a guide rod 15, a guide column 16, a rotating plate 17, and a rotating column 18. One side of the guide rod 15 and the guide column 16 are fixedly connected to one side of the mounting platform 14. One side of the rotating plate 17 is rotatably connected to one side of the mounting platform 14. One side of the rotating column 18 is fixedly connected to the side of the rotating plate 17 away from the mounting platform 14. One side of the mounting block 1 is fixedly connected to the side of the rotating plate 17 away from the mounting platform 14. A rotating motor 19 is fixedly connected to one side of the bottom of the mounting platform 14. The output end of the rotating motor 19 is fixedly connected to the side of the rotating plate 17 near the mounting platform 14. A guide groove 20 is provided on the guide rod 15. The outer walls of the guide column 16 and the rotating column 18 are recessed inward.

[0031] It should be noted that, in actual use, the cable termination is passed through the guide groove 20 and guide post 16 on the guide rod 15, and then pushed further to allow the cable termination to enter the mounting block 1. At this point, the distance between the four clamping plates 7 is adjusted by the drive motor 13 according to the thickness of the cable termination, so that the four clamping plates 7 clamp and fix the cable termination. Then, the rotation motor 19 is started, which drives the rotating plate 17 and rotating post 18 to rotate. At this time, the cable termination fixed inside the mounting block 1 will rotate around... The outer wall of the rotating column 18 is bent to achieve the bending of the cable terminal head. When the device is in use, due to the guide groove 20, the cable terminal head is fixed by four clamping plates 7 during the bending process. Therefore, the other end of the cable terminal head will move with the bending. At this time, the guide groove 20 can ensure that the movement of the moving end is more stable. The specific model of the rotating motor 19 is Y90S-210. This rotating motor 19 is commonly used in bending devices to realize the bending function of the device.

[0032] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
