[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a fully automatic servo electric cylinder includes a base box 1. The top of the base box 1 is fixedly connected to an electric cylinder housing 2. A transmission cylinder 4 is rotatably connected between the inner walls of the electric cylinder housing 2. A threaded body 9 is fixedly connected inside the electric cylinder housing 2. The outer side of the threaded body 9 is rotatably connected to the transmission cylinder 4. A sliding limit plate 6 is slidably connected between the inner walls of the transmission cylinder 4. A threaded movable rod 8 is fixedly connected to one side of the sliding limit plate 6. The outer side of the threaded movable rod 8 is threadedly connected to the inner wall of the threaded body 9. A transmission assembly is provided inside the base box 1. The transmission assembly drives the transmission cylinder 4 to rotate. A flat key 5 is fixedly connected to the inner side of the transmission cylinder 4. A keyway 7 is opened on the outer side of the sliding limit plate 6. The outer side of the flat key 5 is slidably connected to the inner wall of the keyway 7.

[0022] During the operation of the fully automatic servo electric cylinder, the transmission cylinder 4 is driven to rotate between the inner walls of the cylinder housing 2 through the transmission component. Since the outer side of the flat key 5 is slidably connected to the inner wall of the keyway 7, the threaded movable rod 8 can rotate simultaneously with the transmission cylinder 4. The outer side of the threaded movable rod 8 is threadedly connected to the inner wall of the threaded body 9. Therefore, while the threaded movable rod 8 rotates, the sliding limit plate 6 will also move between the inner walls of the transmission cylinder 4, thereby realizing the extension and retraction of the threaded movable rod 8. Through the transmission component, this process converts electrical energy into mechanical energy, further improving the accuracy of the servo electric cylinder during use and making the fully automatic servo electric cylinder more suitable for practical applications.

[0023] like Figures 1-5 As shown, the transmission assembly includes a drive roller 10 and a driven roller 11, both of which are rotatably connected between the inner walls of the base box 1. A transmission belt 12 is provided between the drive roller 10 and the driven roller 11. One end of the driven roller 11 extends into the interior of the electric cylinder housing 2 and is fixedly connected to the transmission cylinder 4. A servo motor 3 is fixedly installed on the top of the base box 1. The output end of the servo motor 3 extends into the interior of the base box 1 and is fixedly connected to the drive roller 10. One side of the drive roller 10, the driven roller 11, and the transmission belt 12 are all provided with transmission teeth, which mesh with each other.

[0024] The servo motor 3 drives the active roller 10 to rotate inside the base box 1. Since the active roller 10, the driven roller 11 and the transmission belt 12 are all provided with transmission teeth on one side, and the transmission teeth mesh with each other, the driven roller 11 will also drive the transmission cylinder 4 to rotate between the inner walls of the electric cylinder housing 2 while the active roller 10 rotates. This makes it convenient to convert electrical energy into mechanical energy through the servo motor 3 to realize the effective operation of the servo electric cylinder.

[0025] The utility model provides a full -automatic servo electric jar, concrete working principle is as follows: in the process of full -automatic servo electric jar work, through servo motor 3 drive driving roller 10 rotates in the inside of base box 1, because driving roller 10, driven roller 11 and the one side of transmission belt 12 all are provided with transmission tooth, and the transmission tooth between each other engages, make in driving roller 10 rotates simultaneously driven roller 11 also will drive transmission cylinder 4 rotates between the inner wall of electric jar casing 2, because the outside of flange key 5 and the inner wall of keyway 7 slide connection, threaded movable rod 8 can with transmission cylinder 4 rotates simultaneously, the outside of threaded movable rod 8 and the inner wall of threaded along body 9 screw connection, thus in threaded movable rod 8 rotates simultaneously, sliding limit stop 6 also will move in the inner wall of transmission cylinder 4 along with, thereby realize the telescopic movement of threaded movable rod 8.
