The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example 1

[0019] A preferred embodiment of the fastening device for fire cylinder valves provided by this utility model is, for example... Figures 1 to 4 As shown: A fastening device for a fire cylinder valve includes: a base 1, support frames 8 welded to both sides of the base 1, a drive assembly 9 installed at the bottom of the support frame 8, a fastening assembly 7 slidably installed below the support frame 8, a clamping assembly 3 installed on the inner walls of both sides of the support frame 8, a conveyor belt 5 installed inside the base 1, a first motor 4 fixed to one side of the base 1 by bolts, and an anti-slip support pad 2 welded to each of the four corners at the bottom of the base 1.

[0020] The drive assembly 9 includes a third motor 901 that is bolted to one side of the support frame 8, and a double-threaded screw 903 is rotatably mounted between the inner walls of the support frame 8 via bearings. The output end of the third motor 901 is fixedly connected to one end of the double-threaded screw 903.

[0021] Two limiting slide rods 902 are welded between the inner walls of the support frame 8, and the two limiting slide rods 902 are located on both sides of the double-threaded screw 903. A second slider 905 is respectively sleeved on the outer side of both ends of the double-threaded screw 903 and the limiting slide rods 902, and the second slider 905 is connected to the double-threaded screw 903 by thread engagement.

[0022] Each of the two second sliders 905 has a connecting rod 906 mounted on its bottom via a pivot, and each of the two connecting rods 906 has a connecting block 904 mounted on its bottom end via a pivot.

[0023] The inner walls on both sides of the support frame 8 are provided with two limiting grooves 6, and the fastening component 7 includes a slide plate 701. Two first sliders 705 are welded to both sides of the slide plate 701, and the first sliders 705 are limited and slidably installed inside the limiting grooves 6. The top of the first sliders 705 is welded to the bottom of the two connecting blocks 904.

[0024] A mounting bracket 704 is welded to the bottom of the skateboard 701, and a second motor 702 is fixed inside the mounting bracket 704 by bolts. A fastening head 703 is installed at the bottom of the mounting bracket 704, and the output end of the second motor 702 is fixedly connected to the top of the fastening head 703.

[0025] In this invention, the fire cylinder to be processed is placed above the conveyor belt 5. Then, the output of the first motor 4 is controlled to rotate, driving the conveyor belt 5 to transport the fire cylinder above the conveyor belt 5 to below the fastening assembly 7. The operator can then adjust the height of the fastening assembly 7 according to the height of the fire cylinder. The output of the third motor 901 is controlled to rotate, driving the double-threaded screw 903 to rotate. The rotation of the double-threaded screw 903 causes the two second sliders 905 to slide relative to each other along the installation direction of the double-threaded screw 903. The bottom of each component is connected to a connecting rod 906 via a rotating shaft. One end of the connecting rod 906 is connected to the top of the slide plate 701 via a connecting block 904 connected to the rotating shaft. Therefore, by controlling the relative sliding of the two second sliders 905 and the transmission of the connecting rod 906, the slide plate 701 can be driven to slide up and down along the opening direction of the limiting slide groove 6, thereby adjusting the distance between the slide plate 701 and the steel cylinder placed on the top of the conveyor belt 5. Then, by connecting the fastening head 703 to the steel cylinder valve, the fastening head 703 is rotated by controlling the rotation of the output end of the second motor 702, thereby fastening the fire cylinder valve.

[0026] The clamping assembly 3 includes a cylinder 301 that is fixed to the inner wall of the support frame 8 by bolts, and a clamping plate 303 is welded to the output end of the cylinder 301. An anti-slip clamping groove 302 is provided on one side of the clamping plate 303, and two support slide rods 304 are welded to one side of the clamping plate 303. One end of the support slide rod 304 slides through the interior of the support frame 8.

[0027] In this utility model, when the fire cylinder to be processed is conveyed by the conveyor belt 5 to the bottom of the fastening assembly 7, the extension of the output end of the two cylinders 301 is controlled to drive the clamping plate 303 to move, so that the anti-slip clamping groove 302 contacts one side of the fire cylinder, thereby fixing and clamping the fire cylinder, preventing the cylinder from rotating during the valve fastening process, thereby improving the stability of the cylinder itself when the valve is fastened, and thus improving the fastening strength of the valve itself.

[0028] Working principle: The steel cylinder to be processed is placed on the conveyor belt. The first motor 4 drives the conveyor belt to send the steel cylinder to the bottom of the fastening assembly 7. The third motor 901 is started, and the double-threaded screw 903 rotates to make the second slider 905 slide relative to it. Through the connecting rod 906 and the connecting block 904, the sliding plate 701 moves up and down. The fastening head 703 is adjusted to a suitable height. The cylinder 301 pushes the clamping plate 303 to move towards the steel cylinder. The anti-slip groove 302 contacts the steel cylinder to form a stable clamp. The support slide rod 304 ensures that the clamping is parallel. The fastening head 703 is aligned with the valve of the steel cylinder. The second motor 702 drives the fastening head to rotate to complete the fastening connection between the valve and the steel cylinder. After the fastening is completed, the clamping assembly 3 is reset, and the conveyor belt 5 sends the steel cylinder to the next process. The device enters the next working cycle.
