[0020] Embodiment

[0021] Please refer to Figures 1-4 As shown, the present utility model provides a fixing device for manufacturing a pressure vessel. Two fixed seats 2 are symmetrically arranged on one side of the base 1. Then, a rotating rod 3 is rotationally connected between the two fixed seats 2 in a limited manner. Then, two arm rods 4 are fixedly sleeved and connected between the two fixed seats 2 outside the rotating rod 3. And at one end of the arm rod 4 and away from the rotating rod 3, a receiving block 5 is rotationally connected in a limited manner through a servo motor. Then, one end of the rotating rod 3 is rotationally connected to the fixed seat 2 in a limited manner, and the other end of the rotating rod 3 passes through the side wall of the fixed seat 2 movably and is connected with a worm gear 6. And a worm 7 is meshed and connected outside the worm gear 6. At the same time, a rotating shaft is fixedly penetrated through the center position of the worm 7, and the rotating shaft is rotationally connected to the side wall of the fixed seat 2 through a connecting seat in a limited manner, and a servo motor is connected to one end of the rotating shaft. Through the setting of the servo motor, the rotating shaft can be rotationally adjusted;

[0022] When placing the pressure vessel on the base 1, first adjust the rotating receiving block 5 through the servo motor so that the opening of the receiving block 5 faces the pressure vessel placed on the ground. Then roll the pressure vessel so that the pressure vessel rolls into the receiving block 5. Next, rotate and adjust the receiving block 5 again through the servo motor. At the same time, manually assist the receiving block 5 to drive the pressure vessel to rotate until the opening of the receiving block 5 faces upward. Then adjust the rotating worm 7. The rotation of the worm 7 drives the rotation of the rotating rod 3 through the meshing of the worm 7 and the worm gear 6. The rotating rod 3 drives the rotation of the arm rod 4. The rotating arm rod 4 lifts the pressure vessel carried on the receiving block 5 until it is rotated and placed on the base 1. During this process, it is necessary to adjust the opening of the rotating receiving block 5 in real time through the servo motor to keep it in an upward state to prevent the pressure vessel carried on the receiving block 5 from falling;

[0023] As a further implementation manner of this embodiment, as Figures 1-4 shown, two sliding grooves 9 are symmetrically opened on the upper surface of the base 1. Then, two double-threaded lead screws 10 are rotatably connected in the two sliding grooves 9 in a limited manner. Then, two sliders 11 are symmetrically sleeved and connected on the outer sides of the two double-threaded lead screws 10. At the same time, a limiting seat 12 is arranged on the upper surfaces of the two sliders 11. A roller 13 is rotatably connected in the limiting seat 12 in a limited manner. And a rubber sleeve for increasing the friction between the pressure vessel and the roller 13 is arranged on the outer side of the roller 13. Then, two insertion holes 14 are symmetrically opened on the upper surface of the slider 11 and on one side of the limiting seat 12. Then, two insertion rods 16 are movably inserted into the two insertion holes 14. The tops of the two insertion rods 16 are commonly connected with a limiting plate 15. Finally, a lockable universal wheel 8 is connected and arranged at the four corners of the bottom wall of the base 1;

[0024] When adjusting and using, first adjust the rotation of the double-threaded lead screw 10. The two sliders 11 are driven to move closer to each other through the threading of the double-threaded lead screw 10. With the movement adjustment of the two sliders 11, the two rollers 13 rotatably arranged on the sliders 11 also move closer to each other until the two rollers 13 move to a suitable position. Then place the pressure vessel on the four rollers 13 and process one side of the pressure vessel. After processing, rotate and adjust the two rollers 13 on one side to rotate and turn over the pressure vessel, and then process the other side of the pressure vessel;

[0025] Specific working principle:

[0026] When fixedly processing a pressure vessel, first adjust the rotating double-threaded lead screw 10. Through the threaded drive of the double-threaded lead screw 10, two sliders 11 move closer to each other. With the movement adjustment of the two sliders 11, two rollers 13 which are rotatably limited on the sliders 11 also move closer to each other until the two rollers 13 move to appropriate positions. Then remove the limit plate 15 from the base 1. Next, place the pressure vessel on the receiving block 5. Then adjust and rotate the worm 7. Drive the rotating rod 3 to rotate through the meshing of the worm 7 and the worm wheel 6. Drive the arm rod 4 to rotate through the rotating rod 3. Lift the pressure vessel placed on the receiving block 5 through the rotating arm rod 4 until it is placed on the four rollers 13 on the base 1. During this process, it is necessary to adjust the opening of the receiving block 5 in real time through the servo motor to keep it in an upward state to prevent the pressure vessel placed on the receiving block 5 from falling. Then insert the limit plate 15 into the upper surface of the base 1, which can prevent the pressure vessel from falling. Then the side surface of the pressure vessel can be processed. After the processing is completed, rotate and adjust the two rollers 13 on one side to rotate and turn over the pressure vessel, and then process the other side surface of the pressure vessel.
