[0028] See Figures 1-3 As shown, the high-speed translation mechanism described in this embodiment includes a base plate 1, a translation plate 2, a drag chain structure 3, and a drive motor 4. The base plate 1 is provided with a slide rail 11 and a helical rack 12. The translation plate 2 is provided with a slider 21. The translation plate 2 is slidably connected to the base plate 1 through the slider 21 cooperating with the slide rail 11. The drag chain structure 3 is installed on the base plate 1 and connected to the translation plate 2. The drive motor 4 is installed on the translation plate 2, and the output end of the drive motor 4 is provided with a helical gear 41, which meshes with the helical rack 12.

[0029] This embodiment has a simple structure and reasonable design. Through the combination of base plate 1, translation plate 2, drag chain structure 3 and drive motor 4, the smooth and high-speed movement of translation plate 2 is achieved. The slide rail 11 and helical rack 12 enable translation plate 2 to move accurately along a predetermined path, while the meshing of helical gear 41 of drive motor 4 with helical rack 12 provides driving force, thereby achieving better high-speed translation.

[0030] In some embodiments, the slide rails 11 are provided in a set, and the set of slide rails 11 are arranged in parallel and spaced apart. The helical racks 12 are spaced between the set of slide rails 11 and are arranged in parallel with the set of slide rails 11.

[0031] In this embodiment, a set of parallel and spaced slide rails 11 increases the stability of the translation plate 2 movement. The helical rack 12 is arranged between the slide rails 11 and is parallel to the slide rails 11, which ensures the smooth meshing of the helical gear 41 and the helical rack 12, thereby improving the operating efficiency and accuracy of the translation mechanism.

[0032] In some embodiments, the base plate 1 is provided with an anti-collision structure 5 for preventing the translation plate 2 from colliding.

[0033] Specifically, the anti-collision structure 5 includes an anti-collision block 51 and an anti-collision rubber ring 52. The anti-collision block 51 is installed on the base plate 1, and the anti-collision rubber ring 52 is installed on the anti-collision block 51.

[0034] More specifically, a set of anti-collision structures 5 is provided at both ends of the base plate 1 to prevent collisions during the forward and backward movement of the translation plate 2.

[0035] In this embodiment, the anti-collision structure 5 helps prevent the translation plate 2 from colliding with the base plate 1 or other components during movement due to unexpected situations (such as excessive speed, control errors, etc.), thereby protecting the safety of the translation mechanism and surrounding equipment. Specifically, the combination of anti-collision block 51 and anti-collision rubber ring 52 not only provides sufficient anti-collision buffering effect, but also reduces the noise and vibration generated during collision, further protecting the safety of the translation mechanism and surrounding equipment.

[0036] In some embodiments, the drive motor 4 is configured as a servo motor.

[0037] In this embodiment, the drive motor 4 is set as a servo motor, which can achieve more precise position control and speed adjustment, and improve the operating accuracy and stability of the translation mechanism.

[0038] In some embodiments, the translation plate 2 is provided with a mounting position 22 for mounting the drive motor 4, and a limiting block 23 is provided on one side of the mounting position 22.

[0039] In this embodiment, by setting a mounting position 22 for mounting the drive motor 4 on the translation plate 2 and providing a limiting block 23 on one side of the mounting position 22, the correct installation and fixation of the drive motor 4 on the translation plate 2 can be ensured, while preventing the motor from shifting or falling off during movement, thus ensuring the normal operation of the translation mechanism.

[0040] In some embodiments, the cable chain structure 3 is connected to the base plate 1 and the translation plate 2 via cable chain sheet metal 31, respectively.

[0041] In this embodiment, the cable chain structure 3 is connected to the base plate 1 and the translation plate 2 through the cable chain sheet metal 31, which ensures the stability and reliability of the cable chain structure 3 during the movement of the translation plate 2.

[0042] In some embodiments, a heightening pad 6 is also included, which is disposed at the bottom end of the base plate 1.

[0043] In this embodiment, the heightening plate 6 can be adjusted to accommodate different working environments or equipment requirements. The heightening plate 6 also enhances the stability and load-bearing capacity of the base plate 1, ensuring the stability and reliability of the translation mechanism during long-term operation.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
