Therefore, the fastening device is needed to rotate and tighten the valve to make the valve firmly installed with the cylinder. Therefore, the fastening device of the cylinder valve is widely used in cylinder production occasions;

[0003] The Chinese patent with the publication number of "CN111546047A" discloses "a fastening device for a fire cylinder valve, comprising a frame, a cylinder clamping mechanism and a valve fastening mechanism are installed on the frame, the valve fastening mechanism comprises an electric adjustable preset torque screwdriver, and the sleeve of the electric adjustable preset torque screwdriver matches and corresponds to the valve". Although it can play the role of "clamping the fire cylinder through the clamping mechanism, and then driving the sleeve of the electric adjustable preset torque screwdriver to move to the valve that covers the fire cylinder, starting and driving the electric adjustable preset torque screwdriver to perform the fastening operation, thereby accelerating the production efficiency, and the torque of driving the electric adjustable preset torque screwdriver can be preset, so that the torque of each fire cylinder valve after tightening is the same", when the fastening device is in use, the sleeve is connected to the valve by means of motor propulsion, and its structure is relatively complicated. When the sleeve is pushed into contact with the cylinder valve, the accuracy is low, and the problem of being unable to connect the valve may easily occur, which also increases the maintenance and replacement costs. In addition, when the valve is tightened by the sleeve, the valve needs to be installed on the rotating drive end before it can be tightened and used. When different types of valves need to be tightened, the sleeve needs to be replaced frequently, which is troublesome to operate. Multiple sleeves cannot be placed together, which brings inconvenience when using valves and sleeves of different types. In addition, when tightening valves of cylinders of different types, motors with different power need to be paired. The motor is a fixed installation structure, and it is troublesome to disassemble and assemble, which makes it impossible to quickly replace the motor, affecting the use of the device. When tightening valves on cylinders of different sizes, the size of the clamping parts also needs to be replaced, and it is impossible to adapt to cylinders of different sizes for clamping, which makes it inconvenient to use cylinders of different sizes for clamping.

[0037] In this embodiment, the guide rail block 23 is fixedly connected to the upper end of the connecting column 22 from top to bottom, and the fastening sleeve 27 passes through the mounting ring 26. The mounting ring 26 slides back and forth between the two guide rail blocks 23 through the ring slider 25. The ring slider 25 can be separated from the guide rail block 23 by sliding forward, thereby separating the fastening sleeve 27, and then the fastening sleeve 27 is driven to rotate by the sleeve plug 13.

[0038] In this embodiment, the support top plate 31 is located behind the first guide rail rod 3, and the piston rod of the downward pressing cylinder 32 penetrates downwardly through the support top plate 31. The downward pressing cylinder 32 is used to drive the support top plate 31 to press downward.

[0039] In this embodiment, the clamping structure 33 includes a pressing link 34, a guide frame 35, an adjusting shaft 36, a mounting frame 37 and a clamping plate 38. The pressing link 34 is located below the supporting top plate 31 and is fixedly connected to the piston rod of the pressing cylinder 32. Two guide frames 35 are fixedly mounted on the front and rear ends of the pressing link 34. The adjusting shaft 36 is fixedly mounted on the inner side of the pressing link 34. Two mounting frames 37 are movably mounted on the lower end of the pressing link 34 through the adjusting shaft 36. The clamping plate 38 is fixedly mounted on the inner side of the mounting frame 37. The ground of the two mounting frames 37 and the clamping plate 38 is triangular, which can fit and clamp the round cylinder.

[0040] In this embodiment, the guide frame 35 is movably sleeved on the outer side of the supporting pole 30, and the two mounting frames 37 are symmetrically arranged and installed around the center of the adjusting shaft 36 and can rotate around it. The clamping plate 38 is located above the conveyor belt 29. The angles of the two clamping plates 38 are adjusted by the rotation of the mounting frame 37. After adjustment, the screws on the adjusting shaft 36 are tightened to lock the position, so that the clamping plate 38 can clamp and position cylinders of different sizes.

[0041] It should be noted that the present invention is a fastening device for a cylinder valve. When in use, the fixed mounting plate 1 plays the role of placing and fixing the device. The cylinder whose valve needs to be locked is placed on the conveyor belt 29 inside the conveyor frame 28. After the conveyor belt 29 is running, it drives the cylinder to move to one side. When the cylinder moves to the bottom of the clamping plate 38, the operation of the down-pressing cylinder 32 drives the down-pressing connecting rod 34 to move downward, thereby moving the lower clamping plate 38 to the outside of the cylinder and clamping it. Then, the operation of the push cylinder 16 drives the sliding mounting frame 10 to move backward around the first guide rail rod 3 by pushing the connecting plate 14, thereby causing the transmission 11 to move backward. When the transmission 11 moves backward, it first drives the connecting plate 14 to move backward. The sleeve plug 13 is inserted into the fastening sleeve 27, and then the fastening sleeve 27 is driven to move backward, and then the fastening sleeve 27 is moved to the cylinder valve for matching connection, and the operation of the locking drive motor 7 drives the motor coupling 8 and the speed coupling 12 to rotate, and the rotation of the speed coupling 12 is transmitted to the sleeve plug 13 and the fastening sleeve 27 through the transmission 11, so that the fastening sleeve 27 is rotated to lock the cylinder valve, and the fastening process of the cylinder valve is completed, and then the cylinder 16 and the pressing cylinder 32 are pushed to reset, so that the pressing plate 38 rises, and the fastening sleeve 27 moves forward. The fastened cylinder is then transported to the other side by the conveyor belt 29, and the fastening process of the next cylinder is carried out;

[0042] When the transmission 11 moves backward, the sleeve plug 13 is inserted into the fastening sleeve 27 and then drives it to move backward, and at the same time drives the installation collar 26 to slide backward between the two guide rail blocks 23 through the collar slider 25, so that the collar slider 25 is separated from the guide rail block 23, and then the fastening sleeve 27 is rotated for use. After one fastening is completed, the cylinder 16 is pushed to reset and drive the transmission 11 to move forward, and also drives the fastening sleeve 27 to move forward, and again the collar slider 25 is inserted into the guide groove 24 on the side of the guide rail block 23 and slides forward, and then the guide rail block 23 limits the collar slider 25, so that the sleeve plug 13 is separated from the fastening sleeve 27;

[0043] When the fastening sleeve 27 needs to be switched, a plurality of fastening sleeves 27 are arranged on the mounting plate 20. By moving the mounting plate 20 left and right, the sliding mounting block 19 slides above the third guide rail rod 18, thereby switching the position of the upper fastening sleeve 27 to switch different fastening sleeves 27 to the rear of the sleeve plug 13. Therefore, when the sleeve plug 13 is connected to the fastening sleeve 27 backwards and the cylinder valve is fastened, fastening sleeves 27 of different models can be installed for fastening use.

[0044] When it is necessary to switch the locking drive motor 7, after loosening the fastening screws of the front and rear connecting rods 17 on the sliding mounting frame 10, the guide rail mounting frame 4 can slide forward alone around the first guide rail rod 3, so that the upper motor coupling 8 is separated from the speed coupling 12, and then the motor mounting frame 6 is slid above the second guide rail rod 5, the positions of the two motor mounting frames 6 and the locking drive motor 7 are switched, and then the guide rail mounting frame 4 is moved backward and reset, so that the motor coupling 8 on the switched locking drive motor 7 is connected to the speed coupling 12, and the front and rear connecting rods 17 are locked in position at the same time, thereby realizing the switching of the locking drive motor 7.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
