[0029] Please refer to Figures 1-5, the present utility model provides a technical solution: an electric clamping actuator, including a driving motor 1, a fixing plate 3 is arranged at the front end of the driving motor 1, a clamping mechanism, the clamping mechanism is arranged inside the fixing plate 3, the clamping mechanism includes a clamping plate 14, the clamping plate 14 is slidably connected to the front end of the fixing plate 3, the surface of the fixing plate 3 is provided with a first chute 13 and a second chute 17, a slider 12 is slidably connected inside the first chute 13, a limiting block 16 is slidably connected inside the second chute 17, and a straight rack 11 is fixedly connected to the surface of the limiting block 16.

[0030] There are two clamping mechanisms, which are symmetrically arranged on both sides of the fixing plate 3 respectively. The two clamping plates 14 are fixedly connected to the corresponding sliders 12 and slidably connected to the other slider 12.

[0031] The output end of the driving motor 1 rotates through the driving box 2 and is fixedly connected with a sun gear 4. A planetary gear carrier 6 is arranged in front of the sun gear 4. Three first rotating shafts 7 are rotatably connected inside the planetary gear carrier 6, and planetary gears 8 are fixedly connected to the surfaces of the three first rotating shafts 7.

[0032] All three planetary gears 8 are meshed with the sun gear 4, and a toothed ring 5 is fixedly connected inside the driving box 2. All three planetary gears 8 are meshed with the toothed ring 5.

[0033] A second rotating shaft 9 is fixedly connected to the front end of the planetary gear carrier 6, a gear 10 is fixedly connected to the surface of the second rotating shaft 9, and the gear 10 is meshed with the two straight racks 11.

[0034] Anti-slip pads 15 are fixedly connected to the surfaces of the two clamping plates 14, and both anti-slip pads 15 are made of rubber.

[0035] When using this electric actuator, start the driving motor 1 to drive the sun gear 4 to rotate, the sun gear 4 drives the planetary gears 8 to rotate, the planetary gears 8 drive the corresponding first rotating shafts 7 to rotate. Since the planetary gears 8 are not only meshed with the sun gear 4 but also meshed with the toothed ring 5, the planetary gears 8 and the first rotating shafts not only rotate on their own axes but also rotate around the sun gear, and the first rotating shafts 7 drive the planetary gear carrier 6 to rotate.

[0036] The planetary gear carrier 6 drives the second rotating shaft 9 to rotate, the second rotating shaft 9 drives the gear 10 to rotate, the gear 10 drives the straight racks 11 and the limiting blocks 16 to move, so that the limiting blocks 16 slide inside the second chute 17, the limiting blocks 16 drive the sliders 12 to slide inside the first chute 13, and the sliders 12 drive the clamping plates 14 and the anti-slip pads 15 to move, facilitating the clamping of objects. By the forward and reverse rotation of the driving motor 1, the clamping plates 14 are opened and closed, and the opening and closing degree of the clamping plates 14 is controlled.

[0037] Since the second chute 17 is provided on the surface of the fixing plate 3, some impurities or dust in the air may enter the interior of the drive box 2 from the second chute 17 during the use of the device. By sliding the slider 12 inside the first chute 13, the second chute 17 is blocked to prevent dust from entering the interior of the drive box 2, which may easily affect the normal operation of the gears, exacerbate the wear of the gears, and even cause equipment failures, thus extending the service life of the device.

[0038] Since the anti-slip pad 15 is made of rubber material, it can provide additional friction during the clamping process, making the clamped material closely fit on the surface of the clamping plate, forming a stable support surface. This can not only prevent the clamping plate from moving or shifting during use, but also improve the stability of the overall structure, ensuring the safety and accuracy of the operation.

[0039] Furthermore, by sliding the slider 12 inside the first chute 13, and the movement of the clamping plate 14 and the anti-slip pad 15, it is convenient to clamp thinner items, expand the moving range of the clamping plate 14, and facilitate the clamping of items. At the same time, the slider 12 can block the second chute 17 to prevent dust from entering the interior of the drive box 2 from the second chute 17, affecting the normal operation of the gears, improving the stability of the device during operation, extending the service life of the device, and enhancing the practicality of the device.

[0040] Through the setting of the anti-slip pad 15, it is convenient to increase the friction between the item and the clamping plate 14. This can not only prevent the clamping plate from moving or shifting during use, but also improve the stability of the overall structure, ensuring the safety and accuracy of the operation, and improving the working precision and efficiency.

[0041] Working principle: When using this electric actuator, start the drive motor 1 to drive the sun gear 4 to rotate. The sun gear 4 drives the planetary gear 8 to rotate, and the planetary gear 8 drives the corresponding first rotating shaft 7 to rotate. Since the planetary gear 8 meshes not only with the sun gear 4 but also with the tooth ring 5, the planetary gear 8 and the first rotating shaft not only rotate on their own axes but also rotate around the sun gear. The first rotating shaft 7 drives the planetary gear carrier 6 to rotate.

[0042] The planetary gear carrier 6 drives the second rotating shaft 9 to rotate. The second rotating shaft 9 drives the gear 10 to rotate. The gear 10 drives the straight rack 11 and the limit block 16 to move, causing the limit block 16 to slide inside the second chute 17. The limit block 16 drives the slider 12 to slide inside the first chute 13. The slider 12 drives the clamping plate 14 and the anti-slip pad 15 to move, facilitating the clamping of items. By the forward and reverse rotation of the drive motor 1, the clamping plate 14 can be opened and closed, and the opening and closing degree of the clamping plate 14 can be controlled.

[0043] Since the surface of the fixing plate 3 is provided with a second chute 17, during the use of the device, some impurities or dust in the air may enter the interior of the drive box 2 from the second chute 17. By sliding the slider 12 inside the first chute 13, the second chute 17 is blocked to prevent dust from entering the interior of the drive box 2, which may easily affect the normal operation of the gears, exacerbate the wear of the gears, and even cause equipment failures, thus prolonging the service life of the device.

[0044] Since the anti-slip pad 15 is made of rubber material, it can provide additional friction during the clamping process, making the clamped material closely fit on the surface of the clamping plate, forming a stable support surface. This can not only prevent the clamping plate from moving or shifting during use, but also improve the stability of the overall structure, ensuring the safety and accuracy of the operation.

[0045] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
