Description

Technical Field

[0001] This invention relates to the field of high-voltage wire harness processing equipment technology, specifically to an automated crimping device for high-voltage wire harnesses. Background Technology

[0002] High-voltage cable harnesses are specialized cables used to transmit high voltage (typically 300V and above) and high current. They are mainly used in high-voltage electrical equipment such as new energy vehicles, serving as the nerve circuits connecting key components such as batteries, motors, and charging systems to ensure efficient and safe power transmission. As a critical connection component of high-voltage systems, the quality of their terminal crimping directly affects the circuit's conductivity stability and operational safety, requiring precise crimping through specialized equipment.

[0003] Traditional high-voltage wire harness crimping devices rely on manual clamping for wire harness fixation, resulting in large positioning deviations and easy misalignment of terminals, affecting connection reliability. Furthermore, the crimping process requires manual adjustment of the crimping position and force, making each crimping session time-consuming and difficult to meet the needs of mass production. In addition, the lack of an effective reset and buffer structure leads to significant equipment vibration during crimping, which not only affects crimping accuracy but also shortens the equipment's lifespan. Therefore, an automated high-voltage wire harness crimping device is proposed. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing an automated crimping device for high-voltage wire harnesses.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: an automated crimping device for high voltage wire harnesses, including a base, with multiple side transmission seats fixedly connected to both sides of the top of the base, the multiple side transmission seats being grouped in pairs, and a clamp fixing mechanism being provided between each group of side transmission seats. A reset buffer mechanism is provided on one side of each of the aforementioned side transmission seats; The top of the base is provided with a pressing mechanism between multiple side transmission seats.

[0006] The beneficial effects of adopting the above-mentioned further solution are that the base provides stable support for the overall device, the top surface is flat, providing a precise installation foundation for components such as the side transmission seat and the pressing seat; the inner wall of the bottom is reserved for installation space to fix the drive motor, ensuring that the power component and other mechanisms operate in coordination; auxiliary components such as the hydraulic pump are installed on one side of the outer wall, the overall structure is stable, and the equipment shaking during the pressing process can be suppressed. The side transmission seats are fixed on both sides of the top of the base, symmetrically distributed and in pairs, providing installation and transmission support for the threaded rod of the clamp fixing mechanism; the inner wall is opened with a transmission hole adapted to the threaded rod to ensure that the threaded rod rotates without deviation, ensuring the movement accuracy of the clamp block; at the same time, it provides a fixed foundation for the side connecting block of the reset buffer mechanism, realizing the coordinated installation of multiple mechanisms.

[0007] The beneficial effects of this invention are: 1) The clamp fixing mechanism of the present invention achieves precise synchronous movement of the clamp blocks on both sides through synchronous transmission of the driving gear and the driven wheel. Combined with the upper and lower clamping of the bottom fixing seat, it ensures that the positioning deviation of the high voltage wire harness is small. The reset buffer mechanism effectively reduces the crimping vibration, further ensures the crimping accuracy, avoids crimping defects caused by positioning offset or vibration, and improves the stability of high voltage wire harness crimping quality.

[0008] 2) In this invention, the clamp fixing mechanism can change the clamp block spacing by adjusting the rotation speed of the threaded rod to adapt to high-voltage wire harnesses of different diameters; the height of the crimping seat can be finely adjusted by the bottom transmission component to adapt to the crimping requirements of different types of terminals; multi-specification wire harness processing can be achieved without replacing core components, reducing equipment replacement costs and improving the versatility of the device.

[0009] 3) This device integrates positioning, crimping, and auxiliary processing functions, eliminating the need for manual transfer of wire harnesses and reducing process connection time; the automated crimping mode enables batch processing, significantly reducing manual intervention. Compared with traditional semi-automatic devices, the single crimping time is shortened, production efficiency is significantly improved, and it meets the needs of large-scale processing of high-voltage wire harnesses.

[0021] Furthermore, a top through rod extends through the top of the connecting frame, a bottom connecting seat is fixedly connected to the bottom of the top through rod, and a cable splitter board is fixedly connected to the bottom of the bottom connecting seat.

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] An automated crimping device for high-voltage wire harnesses has been proposed by the inventors to solve the aforementioned problems.

[0033] The present invention provides the following preferred embodiments. like Figure 1-7 As shown, an automated crimping device for high-voltage wire harnesses includes a base 1. Multiple side transmission seats 11 are fixedly connected to both sides of the top of the base 1, arranged in pairs. The base 1 provides stable support for the entire device. Its flat top surface provides a precise mounting base for components such as the side transmission seats 11 and crimping seats 310. An installation space is reserved on the inner wall of the bottom for fixing the drive motor 4, ensuring the power components operate collaboratively with other mechanisms. An auxiliary component, such as a hydraulic pump 312, is installed on one side of the outer wall. The overall structure is stable and can suppress equipment shaking during crimping. The side transmission seats 11 are fixed to both sides of the top of the base 1, symmetrically distributed and arranged in pairs, providing installation and transmission support for the threaded rod 12 of the clamp fixing mechanism. Transmission holes adapted to the threaded rod 12 are opened on the inner wall to ensure no deviation when the threaded rod 12 rotates, guaranteeing the movement accuracy of the clamp block 18. Simultaneously, a fixed base is provided for the side connecting block 2 of the reset buffer mechanism, enabling collaborative installation of multiple mechanisms.

[0034] A clamping mechanism 01 is provided between each set of side transmission seats 11. The clamping mechanism 01 includes multiple threaded rods 12 penetrating the inner wall of the side transmission seats 11. A top transmission box 13 is fixedly connected to the top of each set of side transmission seats 11. A drive gear 14 is rotatably connected to one side of the inner wall of the top transmission box 13. A transmission belt 15 is drivenly connected to the outer wall of the drive gear 14. A driven wheel 16 is drivenly connected to the end of the two transmission belts 15 away from the drive gear 14. The bottom ends of the two drive gears 14 and the driven wheel 16 are fixed to the top of the threaded rods 12. The threaded rods 12 penetrate the inner wall of the side transmission seats 11 and can rotate around their own axis. The top transmission box 13 is fixed to the top of each set of side transmission seats 11. The drive gear 14 and the driven wheel 16 inside are drivenly connected through the transmission belt 15, and the bottom ends of both are fixed to the top of the threaded rods 12. When the drive gear 14 rotates, it drives the drive belt 15 through the transmission belt 15. The driven wheel 16 rotates synchronously, which in turn drives the two sets of threaded rods 12 to rotate synchronously, ensuring the synchronous movement of the clamping blocks 18 on both sides. The outer walls of the multiple threaded rods 12 are connected to the transmission blocks 17, and the clamping blocks 18 are fixedly connected to one side of the multiple transmission blocks 17. The bottom end of each set of side transmission seats 11 is fixedly connected to the bottom end, and the two bottom end fixing seats 19 correspond to the clamping blocks 18. The transmission blocks 17 are connected to the outer walls of the threaded rods 12. When the threaded rods 12 rotate, the transmission blocks 17 move along the axis of the threaded rods 12. The clamping blocks 18 are fixed to one side of the transmission blocks 17 and open and close with the movement of the transmission blocks 17. The clamping distance can be adjusted according to the specifications of the high-voltage wire harness.

The sliding rod 22 is fixed to the bottom end of the sliding block 21, and the bottom end of the sliding rod 22 is slidably connected to the inner wall of the bottom support leg 23, forming a buffer structure that can slide up and down. During pressing, the vibration generated by the equipment drives the sliding block 21 to slide up and down along the sliding rod 22, initially weakening the vibration. The device transmits vibrations through a series of sliding blocks 21. Side extension blocks 24 are fixedly connected to one side of the outer wall of each sliding block 21. Spring compression rods 25 penetrate the inner walls of the side extension blocks 24. Bottom extension blocks 26 penetrate the bottom ends of the spring compression rods 25. All bottom extension blocks 26 are fixed to one side of the bottom support leg 23. The side extension blocks 24 are fixed to one side of the outer wall of the sliding block 21, and spring compression rods 25 penetrate their inner walls. The bottom end of the spring compression rod 25 penetrates the bottom extension block 26 fixed to one side of the bottom support leg 23, and the rod is fitted with an elastic spring. During vibration, the sliding block 21 drives the side extension blocks 24 to move up and down, causing the spring compression rods 25 to move back and forth. The elastic spring absorbs vibration energy through compression and rebound, further weakening the vibration and ensuring the overall stable operation of the device.

[0036] A pressing mechanism 03 is provided at the top of the base 1 between multiple side transmission seats 11. The pressing mechanism 03 includes a fixed seat 3 fixed to one side of the top of the base 1. Connecting seats 31 are fixedly connected to one side of the outer wall of two fixed seats 3.

The fixed seat 3 is fixed to one side of the top of the base 1 to provide installation support for the connecting seats 31. The linkage rods 32 are rotatably connected to both sides of the outer wall of the connecting seats 31 through limit blocks 33. The limit blocks 33 ensure that the linkage rods 32 can rotate. The trajectory is stable; the end of the linkage rod 32 away from the connecting seat 31 is rotatably connected to the linkage frame 35. One end of the linkage frame 35 is fixed to the handle 34, and the other end is fixed to the connecting frame 36. When the operator pushes the handle 34, the linkage frame 35 and the connecting frame 36 can be moved up and down through the linkage rod 32.

The tops of the two crimping seats 310 have crimping grooves 311. Two cable branch plates 39 are located on one side of the crimping grooves 311. The crimping seats 310 are fixed to the top of the base 1, located on one side of the fixed seats 3, with crimping grooves 311 on their tops, corresponding vertically to the cable branch plates 39. During automated crimping, the connecting frame 36 moves the cable branch plates 39 downwards, pressing the wiring harness into the crimping grooves 311 and branching it for easier subsequent crimping. A hydraulic pump 312 is rotatably connected to one side of the outer wall of the base 1. The output end of the hydraulic pump 312 is rotatably connected to a top rotating seat 313. The top of the top rotating seat 313 is fixedly connected to... A top support rod 314 is rotatably connected to a bottom rotating rod 315 near its center.

Its output end is connected to the top support rod 314 through a top rotating seat 313. The support rod 316 is connected to the bottom of the top support rod 314 near its center via the bottom rotating rod 315. The support rod 316 is fixed to the top of the base 1, forming a lever structure.When driven by the hydraulic pump 312, the top support rod 314 can be rotated around the bottom rotating rod 315, realizing the up and down movement of the welding plate 317. The top heater 318 is fixed to one end of the top support rod 314 and electrically connected to the welding plate 317, which can heat the welding plate 317. The welding plate 317 moves down to heat the crimping area, and then the wire harness moves and crimps through the cable distribution plate 39, thereby improving the crimping reliability.

[0037] A drive motor 4 is fixedly connected to the inner wall of the bottom end of the base 1. A motor rod 41 is fixedly connected to the output end of the drive motor 4. A meshing gear 42 is installed on the outer wall of the motor rod 41, and a transmission wheel set 43 is installed on the top of the meshing gear 42 on the outer wall of the motor rod 41. Threaded rods 44 are installed on the inner walls of both the transmission wheel set 43 and the meshing gear set 42. Top transmission rods 45 are connected to the top ends of both threaded rods 44. Both top transmission rods 45 are fixed to the bottom end of the pressing seat 310. The drive motor 4 is fixed to... The inner wall of the bottom of the base 1 has a motor rod 41 fixed at the output end; the outer wall of the motor rod 41 is equipped with a meshing gear 42 and a transmission wheel set 43, and the inner wall of both is equipped with a threaded rod 44; when the drive motor 4 starts, it drives the motor rod 41 to rotate, and drives the threaded rod 44 to rotate synchronously through the meshing gear 42 and the transmission wheel set 43; the top of the threaded rod 44 is connected to the top transmission rod 45, which is fixed to the bottom of the crimping seat 310 and can drive the crimping seat 310 to make slight up and down adjustments to adapt to the crimping height requirements of different specifications of wire harnesses.

[0038] The specific steps for using this invention are as follows: In use, first, place the high-voltage wire harness to be crimped into the crimping groove 311 of the crimping seat 310, and adjust the position of the wire harness so that the crimping point of the terminal is directly below the cable branch plate 39; at the same time, place the wire harness on the top of the bottom fixing seat 19, ensuring that the wire harness is in a horizontal state without twisting or deviation, start the drive component of the clamp fixing mechanism, the drive gear 14 rotates and drives the driven wheel 16 to rotate synchronously through the transmission belt 15, thereby driving the two sets of threaded rods 12 to rotate synchronously; the transmission block 17 Move the threaded rod 12 towards the wire harness, causing the clamp block 18 to move downwards until it is tightly fitted against the top of the wire harness, forming a clamping and fixing mechanism with the bottom fixing seat 19. This ensures that the wire harness does not shift during crimping. Push the rotating handle 34, which, through the linkage rod 32 and linkage frame 35, causes the connecting frame 36 to move downwards. This causes the top through rod 37, the bottom connecting seat 38, and the cable branch plate 39 to move downwards simultaneously. The cable branch plate 39 branches the wire harness for easier subsequent crimping. During the crimping process, the equipment generates... Vibration is transmitted to the reset buffer mechanism through the side transmission seat 11. The sliding block 21 slides up and down along the sliding rod 22. The side extension block 24 drives the spring compression rod 25 to move synchronously. The elastic spring absorbs vibration energy through compression and rebound, weakening the impact of vibration on crimping accuracy and ensuring the stability of the crimping process. The hydraulic pump 312 is started, and its output end pushes the top rotating seat 313, causing the top support rod 314 to rotate around the bottom rotating rod 315, which drives the welding plate 317 to move down to the crimping position. The preheated welding plate 317 heats and reinforces the crimping part, improving the connection reliability between the terminal and the wire harness. After the treatment is completed, the hydraulic pump 312 is reset, driving the welding plate 317 to move up and away from the crimping part. Then the wire harness is pushed to connect. The clamp fixing mechanism is started, driving the drive gear 14 in the reverse direction, causing the threaded rod 12 to rotate in the reverse direction. The transmission block 17 drives the clamp block 18 to move up, releasing the clamp on the high-voltage wire harness.
