[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Example Reference Figures 1-5 This embodiment of the invention provides a transverse cutting device for flexible cable following cutting, comprising a tool setting module 1, a cutting module 2, a tool setting track drive module 3, and a tool setting screw drive module 4. This device is designed to achieve precise transverse cutting during the production or processing of flexible cables, ensuring stable and reliable cutting quality, while also possessing flexible tool setting adjustment capabilities to adapt to the cutting needs of cables of different specifications.

[0026] Specifically, the tool setting module 1 includes a connecting base plate 5, which serves as the mounting foundation for the entire device. A first connecting plate 6, a second connecting plate 7, and a third connecting plate 8 are sequentially fixed to the surface of the connecting base plate 5. These connecting plates are used to support and position other modules, ensuring the stability of the overall structure and the relative positional accuracy between the components.

[0027] The cutting module 2 includes a first motor clamp 29, on the inner side of which a first 57 brushless DC motor 31 is mounted. A first coupling 33 is mounted on the output end of the first 57 brushless DC motor 31. A second coupling 34 is mounted on the output end of the second 57 brushless DC motor 32. A first tool holder 35 is mounted on the output end of the first coupling 33. A first cross-cutting cutter 37 is mounted on the first tool holder 35. A first cross-cutting cutter holder pressure head 39 is also provided on the outer side of the first cross-cutting cutter 37 to fix the tool and ensure its stability under high-speed rotation. The cutting module 2 also includes a second motor clamp 30. A second 57 brushless DC motor 32 is mounted on the inner side of the second motor clamp 30. A second coupling 34 is mounted on the output end of the second 57 brushless DC motor 32. A second cutter shank 36 is mounted on the output end of the second coupling 34. A second cross-cutting cutter 38 is mounted on the second cutter shank 36. A second cross-cutting cutter shank pressure head 40 is also provided on the outer side of the second cross-cutting cutter 38. The first 57 brushless DC motor 31 and the second 57 brushless DC motor 32 drive the first cross-cutting cutter 37 and the second cross-cutting cutter 38 to rotate at high speed, thereby completing the transverse cutting of the flexible cable. The dual-motor, dual-cutter design not only improves cutting efficiency but also enhances the reliability of the flexible cable following cutting device, ensuring stable completion of the cutting task during continuous operation.

[0028] The tool-setting track drive module 3 includes a cross-cutting module pulley connecting plate 25. A cross-cutting tool-setting motor connecting plate 24 is fixed to one side of the top of the cross-cutting module pulley connecting plate 25. A third cross-cutting bearing 20 is installed on the cross-cutting tool-setting motor connecting plate 24 to support the output shaft of the motor 26 and reduce friction. The motor 26 is installed on the outside of the cross-cutting tool-setting motor connecting plate 24. The output shaft of the motor 26 passes through the third cross-cutting bearing 20, and the output end of the motor 26 is connected to a second cross-cutting synchronous pulley 22 via a coupling. A synchronous belt 23 is connected to the outside of the second cross-cutting synchronous pulley 22, and the other end of the synchronous belt 23 is connected to a first cross-cutting synchronous pulley 21. This module acts as an intermediary for power transmission, smoothly and accurately transmitting the rotational motion of the motor 26 to the subsequent tool-setting screw drive module 4 through the synchronous belt 23.

[0029] The lead screw drive module 4 includes a cross-cutting base plate 15 synchronously mounted on a first connecting plate 6, a second connecting plate 7, and a third connecting plate 8. A first lead screw fixing block 11 and a second lead screw fixing block 12 are fixed to both sides of the cross-cutting base plate 15, respectively. A cross-cutting bearing fixing seat 16 is fixedly mounted on the inner side of the first lead screw fixing block 11, and a first cross-cutting bearing 17 is mounted on the cross-cutting bearing fixing seat 16. A first cross-cutting bearing 17 is also provided on the inner side of the second lead screw fixing block 12. A cross-cutting lead screw 18 passes through the interior of the first cross-cutting bearing 17, and a first cross-cutting slider 13 and a second cross-cutting slider 14 are respectively sleeved on the cross-cutting lead screw 18. This module is responsible for converting the tool setting power into precise linear motion to drive the cutting tool for position adjustment.

[0030] The two ends of the connecting base plate 5 are respectively provided with a tool setting sensor fixing plate 10 and a cutting sensor fixing plate 9. The tool setting sensor fixing plate 10 is fixedly installed with a tool setting sensor to detect whether the tool has reached the preset tool setting position. The cutting sensor fixing plate 9 is fixedly installed with a cutting sensor cutting module 2 to monitor the cutting process or the cutting position of the tool, so as to ensure the accuracy and consistency of each cut.

[0031] Furthermore, the cross-cutting module pulley connecting plate 25 is installed on the outside of the cross-cutting base plate 15, so that the entire transmission structure is tightly integrated with the main body of the cutting module 2, saving space and facilitating maintenance.

[0032] The first cross-cutting synchronous pulley 21 is coaxially and fixedly connected to the cross-cutting lead screw 18. It is used to transmit the power of the motor 26 to the cross-cutting lead screw 18 through the synchronous belt 23, thereby driving the lead screw to rotate.

[0033] The first transverse cutting slider 13 and the second transverse cutting slider 14 are both threadedly engaged with the transverse cutting screw 18. When the transverse cutting screw 18 rotates, due to the guiding effect of the threads, the first transverse cutting slider 13 and the second transverse cutting slider 14 will move linearly on the screw.

[0034] The outer sides of the first cross-cutting slider 13 and the second cross-cutting slider 14 are respectively fixedly mounted with a first cross-cutting tool connecting plate 27 and a second cross-cutting tool connecting plate 28. Simultaneously, the first motor clamp 29 and the second motor clamp 30 are respectively fixedly mounted on the first cross-cutting tool connecting plate 27 and the second cross-cutting tool connecting plate 28, thereby achieving the installation connection between the motor clamps and the cross-cutting sliders. This structure allows the cutting module 2 to move as a whole with the movement of the sliders, completing the tool setting action.

[0035] Through the coordinated arrangement of the motor 26, the first cross-cutting synchronous pulley 21, the second cross-cutting synchronous pulley 22, the synchronous belt 23, the cross-cutting lead screw 18, and the slider, the motor 26 can precisely control the linear motion of the first cross-cutting slider 13, the second cross-cutting slider 14, and the cutting tools mounted on them, thereby completing automatic tool setting. This design significantly increases the degree of freedom of the flexible cable following cutting device during cutting, enabling it to adapt to cables of different diameters or different cutting positions, and improving the versatility and automation level of the equipment.

[0036] In use, when the cable to be processed passes through this mechanism, the tool setting sensor is positioned by controlling the rotation of the main shaft of the motor 26, which causes the second cross-cutting synchronous pulley 22 to rotate, driving the synchronous belt 23 to rotate, which in turn drives the first cross-cutting synchronous pulley 21 to rotate, controlling the rotation of the cross-cutting screw 18, causing the first cross-cutting slider 13 and the second cross-cutting slider 14 to move, driving the first cross-cutting cutter 37 and the second cross-cutting cutter 38 to approach the cable to be processed for tool setting.

[0037] When the tool setting is completed, the cable to be processed moves forward. When it passes the cutting sensor, the spindles of the first 57 brushless DC motor 31 and the second 57 brushless DC motor 32 are controlled to rotate, causing the first cross-cutting cutter 37 and the second cross-cutting cutter 38 to rotate, and finally complete the cross-cutting.

[0038] In summary, by using the motor 26, the first cross-cutting synchronous pulley 21, the second cross-cutting synchronous pulley 22, and the synchronous belt 23, the motor 26 drives the first cross-cutting slider 13, the second cross-cutting slider 14, and other parts to complete the tool setting, increasing the degree of freedom of the flexible cable following cutting device during cutting. At the same time, the first 57 DC brushless motor 31 and the second 57 DC brushless motor 32 cause the second cross-cutting milling cutter 38 to rotate, thereby completing the transverse cutting and enhancing the reliability of the flexible cable following cutting device.
