Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment: Please refer to Figures 1-3 , the present invention provides a technical solution: a center rod feeding mechanism of a center rod assembling machine, including a chassis 1 and a base 6. The base 6 is located on one side of the chassis 1. An arc groove 2 is opened at the top of the chassis 1. A turntable 3 is rotatably arranged in the inner cavity of the arc groove 2. A plurality of connecting seats 4 are annularly distributed above the turntable 3. A center rod 5 is movably arranged in the inner cavity of the connecting seat 4. A support rod 7 is arranged on the top of the base 6. One end of the support rod 7 is connected to a mounting seat 9. A main beam 8 is arranged on the front surface of the mounting seat 9. First cylinders 10 are arranged at both ends of the front surface of the main beam 8. One end of the first cylinder 10 is connected to a slide plate 11. A chute 14 is penetrated through the inner cavity of the slide plate 11. A slide bar 15 is sleeved in the inner cavity of the chute 14. A second cylinder 12 is arranged on the front surface of the slide plate 11. One end of the second cylinder 12 is connected to a third cylinder 13.

[0022] Among them, a slide rail 24 is arranged at the bottom of the third cylinder 13. A limit slider 25 is movably arranged at the bottom of the slide rail 24. A connecting block 26 is arranged on one side of the limit slider 25. One end of the connecting block 26 is connected to an arc-shaped clamping plate 27.

[0023] Among them, a movable groove 33 is opened in the inner cavity of the limit slider 25. A fixed block 32 is arranged at the end of the movable groove 33. A buffer spring 31 is arranged on one side of the fixed block 32. One end of the buffer spring 31 is provided with a limit rod 29. One end of the limit rod 29 is fixedly connected to one side of the connecting block 26.

[0024] In this embodiment, by Figure 1As shown in the figure, a central rod 5 is provided above each of the multiple connecting seats 4. When the central rod 5 above one of the connecting seats 4 is removed, the motor and other devices at the bottom of the turntable 3 will drive the turntable 3 to rotate by a certain amplitude, so as to ensure that there is always a central rod 5 below the arc-shaped clamping plate 27, so as to achieve the purpose of continuous feeding; during use, the second cylinder 12 pushes down the third cylinder 13, and the third cylinder 13 clamps the central rod 5 through the arc-shaped clamping plate 27. After the clamping is completed, the third cylinder 13 resets. At this time, the first cylinder 10 pushes the slide plate 11, and the slide plate 11 drives the third cylinder 13 to move axially through the second cylinder 12 until the third cylinder 13 is above the area where the material is to be placed. At this time, the second cylinder 12 drives the third cylinder 13 to move down again and releases the clamping of the arc-shaped clamping plate 27 on the central rod 5, and the feeding work of the central rod 5 can be completed; the arc-shaped clamping plate 27 conforms to the shape of the central rod 5, and there are more areas in contact with the central rod 5 during clamping to improve the clamping stability; the third cylinder 12 drives the arc-shaped clamping plate 27 to clamp the central rod 5 in the same way as a finger cylinder. The finger cylinder is a prior art and will not be elaborated here; affected by the thrust of the buffer spring 31, when the third cylinder 13 is not started, there is a certain gap between the arc-shaped clamping plate 27 and the limit slider 25 to provide a buffer distance when clamping the central rod 5, so as to avoid damage to the central rod 5 due to excessive clamping force of the device and improve the safety of the device. When the third cylinder 12 is started, the two limit sliders 25 gradually approach. At this time, the two arc-shaped clamping plates 27 first come into contact with the central rod 5. During the process of the continuous approach of the limit slider 25, relatively speaking, the arc-shaped clamping plate 27 gradually approaches one side of the limit slider 25. At this time, the arc-shaped clamping plate 27 compresses the buffer spring 31 through the limit rod 29, and at this time the buffer spring 31 pushes back the arc-shaped clamping plate 27, so that the arc-shaped clamping plate 27 can firmly fit on the surface of the central rod 5, so as to prevent the central rod 5 from falling during the transfer process of the device, thereby improving the stability of the device.

[0025] Among them, a plurality of protective pads 28 are distributed on the side wall of the arc-shaped clamping plate 27.

[0026] In this embodiment, the protective pad 28 is made of silica gel, which can improve the friction between the arc-shaped clamping plate 27 and the central rod 5 to a certain extent, further improve the clamping stability of the device, and the silica gel material is relatively soft, which can avoid scratching the central rod 5 by the arc-shaped clamping plate 27, and further improve the practicality of the device.

[0027] Among them, air pipe interfaces 16 are provided on the first cylinder 10, the second cylinder 12 and the third cylinder 13, and a sealing sleeve 17 is connected to the inner wall of the air pipe interface 16.

[0028] In this embodiment, the sealing sleeve 17 can improve the sealing performance between the tracheal interface 16 and the trachea, avoiding air leakage and other situations during the use of the device, thereby further enhancing the use stability and reliability of the device.

[0029] Among them, limiting grooves 21 are formed in the front and side surfaces of the first cylinder 10. A slider 20 is movably arranged in the inner cavity of the limiting groove 21, and a vision sensor 19 is arranged on one side of the slider 20.

[0030] In this embodiment, the vision sensor 19 plays a detection role, which can prevent the device from colliding with external objects during operation, thereby enhancing the use safety of the device. The slider 20 is slidably connected to the limiting groove 21 and is limited by bolts, which can facilitate the adjustment of the position of the slider 20 in the limiting groove 21 according to actual situations, so as to facilitate the adjustment of the height of the vision sensor 19, enabling the vision sensor 19 to still provide a detection function for the device in different environments, and further enhancing the applicability of the device.
