[0023] The following is a detailed description of the specific settings and functions of this embodiment. During the welding process of the fire extinguisher cylinder, the cylinder is placed on the three groups of connecting rods 10, and the welding edges of the flanges at both ends of the cylinder are respectively clamped on one side of the two groups of fixing plates 5, so that the cylinder is fixed on the three groups of connecting rods 10 without displacement. Then the upper head shell is placed on one side of the upper limit seat 7, so that the curvature of its shape fits the recessed part of the upper limit seat 7, and the welding edge is clamped on one side of the upper limit seat 7, and then the lower head shell is placed on the top of the lower limit seat 8, so that the welding edge is clamped on one side of the lower limit seat 8. After all three groups are placed in position, start the two groups of cylinders 9 to drive the upper limit seat 7 and the lower limit seat 8 to move toward the center position respectively, and the upper limit seat 7 drives the upper head shell to move along the limit rod 6, and the lower limit seat 8 drives the lower head shell to move along the limit rod 6 until the upper limit seat 7 is in the correct position. After the welding edge of the head shell contacts the welding edge of the cylinder, and the welding edge of the lower head shell contacts the welding edge on the other side of the cylinder, start the cylinder 1 4 to push the movable platform 2 to move upward, and the movable platform 2 drives the four groups of guide rods 3 to pass through the interior of the fixed platform 1, and the movable platform 2 drives the cylinder, the upper head shell and the lower head shell to move together to the welding workbench for welding. By setting the upper limit seat 7, the lower limit seat 8 and two groups of cylinders 2 9, the bottle mouth, the upper head shell, the cylinder and the lower head shell can be adjusted and clamped at one time, and then the cylinder 2 9 lifts it up and sends it to the welding platform, so as to facilitate the subsequent one-time welding, so that multiple alignments are not required during the welding process, thereby reducing the error during welding, improving the welding quality, ensuring the consistency of the weld, and then ensuring the sealing and structural strength of the fire extinguisher cylinder, and improving the welding efficiency.

[0024] Embodiment 2

[0025] like Figure 4 As shown, bolts 11 are provided through the interior of the two sets of fixing plates 5 , and nuts 12 are threadedly connected to one end of the two sets of bolts 11 , and one side of the two sets of nuts 12 are fixedly installed to one side of the two sets of fixing plates 5 respectively.

[0026] The effect achieved by the entire embodiment is that before welding the cylinder body, the position of the bolt 11 is first adjusted according to the thickness of the cylinder body welding edge and the upper head welding edge, and according to the combined thickness of the two, one end of the bolt 11 is extended out of the fixing plate 5, and then the nut 12 is rotated to fix the position of the bolt 11, and then the cylinder body, the upper head shell and the lower head shell are fixed, and the two groups of cylinders 2 9 are started to drive the upper limit seat 7 and the lower limit seat 8 to move. When one side of the upper limit seat 7 and the lower limit seat 8 contacts one side of the bolt 11, the cylinder body welding edge is just in contact with the upper head welding edge, and the welding edge on the other side of the cylinder is just in contact with the welding edge of the lower head shell. By setting the bolt 11 and the nut 12, the moving distance of the cylinder 2 9 is limited, so that the welding edges are just in contact while avoiding deformation caused by excessive extrusion, thereby ensuring the smooth progress of subsequent welding, ensuring the neatness of the welding edges, and ensuring the sealing of the welding.

[0027] The use method and working principle of the device: before welding the cylinder, first adjust the position of the bolt 11 according to the thickness of the welding edge of the cylinder and the welding edge of the upper head, and according to the added thickness of the two, extend one end of the bolt 11 out of the fixing plate 5, and then rotate the nut 12 to fix the position of the bolt 11. During the welding process of the fire extinguisher cylinder, the cylinder is placed on three groups of connecting rods 10, and the welding edges of the flanged edges at both ends of the cylinder are respectively clamped on one side of the two groups of fixing plates 5, so that the cylinder is fixed on the three groups of connecting rods 10 without displacement, and then the upper head shell is placed on one side of the upper limit seat 7, so that its outer curvature fits the depression of the upper limit seat 7, and the welding edge is clamped on one side of the upper limit seat 7, and then the lower head shell is placed on the top of the lower limit seat 8. So that its welding edge is stuck on one side of the lower limit seat 8. After all three groups are placed in position, start the two groups of cylinders 2 9 to drive the upper limit seat 7 and the lower limit seat 8 to move to the center position respectively. The upper limit seat 7 drives the upper head shell to move along the limit rod 6, and the lower limit seat 8 drives the lower head shell to move along the limit rod 6. When one side of the upper limit seat 7 and the lower limit seat 8 contacts one side of the bolt 11, the welding edge of the upper head shell contacts the welding edge of the cylinder, and the welding edge of the lower head shell contacts the welding edge of the other side of the cylinder. Then start cylinder 1 4 to push the moving platform 2 to move upward. The moving platform 2 drives the four groups of guide rods 3 to pass through the interior of the fixed platform 1. The moving platform 2 drives the cylinder, the upper head shell and the lower head shell to move together to the welding workbench for welding.
