[0030] The production line conveyor frame 1 is composed of a double-group frame body, and the top of the double-group frame body is recessed with a drag chain groove 101. An external valve 102 close to the welding sleeve 3 is arranged on the outer wall of the frame of the production line conveyor frame 1. When the external equipment transfers the semi-finished gas storage cylinder close to the side of the cylinder jacket 4, the external valve 102 is synchronously arranged on the frame body of the loading area of ​​the production line conveyor frame 1, and a valve seat docking with the external valve 102 is arranged on the external equipment, and the valve seat is connected to the external gas supply equipment;

Multiple groups of inner roller members 405 are arranged in a circular array, and the inflatable airbag cushions 406 are embedded in the edges on both sides of the inner wall of the bottom sleeve 401 and the top sleeve 404. Two groups of inflatable airbag cushions 406 on the same side are spliced ​​to form a ring.

[0034] Brackets 201 are symmetrically mounted on the top of both ends of the welding matching frame 2, and a pushing cylinder frame 202 connected to the welding sleeve 3 is embedded on the top of the bracket 201. Transverse grooves close to the production line conveyor frame 1 are recessed on the outer walls on both sides of the welding matching frame 2, and an inner pushing cylinder 203 connected to the end cover feeding frame 6 is embedded inside the transverse groove.

[0035] A moving block 601 is provided at the bottom of the lifting cylinder frame 602 and is slidably sleeved with the horizontal groove. A limit frame drag 603 is sleeved on the top outer wall of the lifting cylinder frame 602. The adapter clamp 604 is slidably sleeved on the inner wall of the lifting cylinder frame 602. The limit frame drag 603 is not limited to that shown in the drawing and is replaced according to the actual shape of the end cover.

[0036] The end cap semi-finished product is transported to the top of the end cap feeding rack 6 by the corresponding external transport equipment, and the external transport equipment is connected to the end cap feeding rack 6 through the limit frame drag 603, and transports the end cap semi-finished products one by one to between multiple groups of adapter clamps 604, and the mechanical arm or related accessories on the external transport equipment adjust the state of the end cap semi-finished product between the adapter clamps 604, and the lifting cylinder rack 602 drives the end cap semi-finished product to slide down through the adapter clamp 604 until it is aligned with the gas storage cylinder semi-finished product on the cylinder jacket 4, and the inner push cylinder 203 drives the end cap feeding rack 6 to slide axially along the welding matching rack 2 through the moving block 601 until the end cap semi-finished product is sleeved on the gas storage cylinder semi-finished product.

[0037] A symmetrical holder 301 is provided at the bottom of the welding sleeve 3, and an annular groove is recessed on the inner wall of the welding sleeve 3 on the side close to the production line conveyor frame 1, and the welding clamp 304 is slidably sleeved in the annular groove. A rotating motor connected to the welding clamp 304 is provided at the bottom of the welding sleeve 3, and multiple groups of welding clamps 304 are provided with metal rings on the outer periphery and sleeved in the annular groove.

[0038] When the temporary connecting air path is formed, under the control of the external air supply device, the telescopic cylinder 403 is expanded, and the telescopic cylinder 403 drives the top sleeve 404 to slide vertically upward until the bottom sleeve 401 and the top sleeve 404 are separated from each other, so that the external device can transfer the semi-finished gas storage cylinder to the bottom sleeve 401. The telescopic cylinder 403 drives the top sleeve 404 to slide down and reset again, and at the same time, the multiple groups of inflatable airbag cushions 406 are inflated synchronously;

[0039] After the top sleeve 404 slides down and resets, the semi-finished gas cylinder is limitedly clamped in the middle of the cylinder jacket 4, and the airbag surface of the inflatable airbag cushion 406 is flexibly contacted and clamped with the outer wall of the semi-finished gas cylinder, so as to increase the clamping friction of the semi-finished gas cylinder and avoid surface damage caused by the rigid clamping of the bottom sleeve 401 and the top sleeve 404 during transportation. It should be noted that a branch pipe separately connected to the inflatable airbag cushion 406 and the telescopic cylinder 403 is arranged inside the valve mouth, and a branch pipe for connecting multiple groups of branch pipes is arranged inside the valve seat, which can realize the regulated air supply expansion and deflation operation under the regulation of external air supply equipment.

[0040] A valve seat connected to an external air supply device is provided at the bottom of the welding sleeve 3 near the production line conveyor frame 1. As the welding sleeve 3 approaches, the valve seat is connected to the welding sleeve 3 by an adjusting cylinder. The welding sleeve 3 is driven by the propulsion cylinder 306 frame to approach the outer side of the end cover semi-finished product until the outer wall of the end cover semi-finished product is embedded in the welding sleeve 3. The propulsion cylinder 306 drives the extrusion plate 303 to slide axially until it contacts the outer wall of the end cover semi-finished product. An electromagnet is embedded in the middle of the inner wall of the extrusion plate 303. The electromagnet is energized to generate magnetic force, which magnetically attracts the end cover semi-finished product to the extrusion plate 303. In this state, the end cover feeding frame 6 releases the clamping of this group of end cover semi-finished products and resets to take over the next group of end cover semi-finished products.

[0041] A cross sleeve 305 is provided on the inner wall of the welding sleeve 3 away from the production line conveyor frame 1 , and a propulsion cylinder 306 is sleeved on the outer wall of the cross sleeve 305 . The extrusion plate 303 is located inside the welding sleeve 3 and connected to the propulsion cylinder 306 .

[0042] Beam bodies connected to the production line conveying frame 1 and the welding matching frame 2 are arranged at both ends of the rotating mechanism 5. Multiple groups of lifting cylinders 501 are symmetrically sleeved on the inner wall of the beam body. Slides 502 are arranged between the lifting cylinders 501 symmetrically on the same side. Contact rollers 503 are sleeved between the multiple groups of slides 502. A servo motor 504 connected to the contact roller 503 is arranged at the bottom of the slide 502.

[0043] During the sleeve connection between the end cover semi-finished product and the gas cylinder semi-finished product, the rotating mechanism 5 and the welding sleeve 3 are started synchronously, and the lifting cylinder 501 drives the slide 502 to slide upward until the contact roller 503 abuts against the outer wall of the bottom of the gas cylinder semi-finished product, and the servo motor 504 drives the contact roller 503 to rotate through the coupling and other accessories. The contact roller 503 contacts and rubs against the outer wall of the semi-finished gas cylinder, thereby driving the semi-finished gas cylinder to rotate synchronously.

[0044] During the period when the extrusion plate 303 magnetically clamps the semi-finished end cap, the semi-finished end cap and the semi-finished gas storage cylinder are in a sleeved and unfixed state, and the regulating cylinder member on the welding sleeve 3 drives the valve seat to extend until it docks with the external valve 102, forming a temporary connected gas path again, and the external gas supply device adjusts the inflatable airbag cushion 406 to make it concave, loosening the frictional flexible clamping of the semi-finished gas storage cylinder, and the multiple groups of inner roller members 405 slightly contact the outer wall of the semi-finished gas storage cylinder;

[0045] In this state, the semi-finished gas cylinder contacts the contact roller 503 and rotates along with the contact roller 503, so as to adjust the fitting between the semi-finished gas cylinder and the semi-finished end cover. After the fixed circle rotates, the inflatable airbag cushion 406 inflates again, forming a frictional flexible clamping limit for the semi-finished gas cylinder, and at the same time, the propulsion cylinder 306 further pushes the extrusion disk 303 toward the center until the extrusion limit is locked between the semi-finished end cover and the semi-finished gas cylinder.

[0046] The rotating motor is connected to the metal ring sleeve through a coupling and a gear, which is used to drive the metal ring sleeve to rotate along the annular groove, and multiple groups of micro-welding machines are installed inside the welding sleeve 3 through the welding clamp 304. The welding clamp 304 follows the metal ring sleeve to rotate along the annular groove, and the semi-finished gas cylinder product and the semi-finished end cover product are subjected to rotational linkage welding processing at fixed positions to obtain the finished gas cylinder. Regarding the sleeve welding area of ​​the semi-finished gas cylinder product and the semi-finished end cover product, the position of the micro-welding machine on the welding clamp 304 is adjusted according to the models of the two, and the angle adjustment function of the micro-welding machine is used for multi-mode adjustment. The welding clamp 304 is not limited to the figure shown, and is replaced and adjusted according to the actual model of the micro-welding machine. After waiting for the welding to be completed, the welding sleeve 3 is reset away from the production line conveyor frame 1, and the cylinder jacket 4 transfers the finished gas cylinder product to the next process area.

[0047] In combination with Example 1 and Example 2, the present invention realizes the smooth transfer of the semi-finished gas cylinder to the production line through components such as the cylinder jacket 4 and the production line conveyor frame 1. The external valve 102 constructs a temporary gas path to facilitate accurate reception and flexible clamping, and the end cover feed frame 6 cooperates with the adapter clamp 604 to accurately feed and adjust the end cover state, thereby realizing accurate socketing with the semi-finished gas cylinder.

[0048] During welding, the welding sleeve 3 constructs a temporary gas path control clamp, the electromagnet fixes the end cover, and the rotating motor drives the micro welding machine to weld in all directions. Combined with the adjustability of the welding clamp 304, it adapts to the requirements of different models, ensures firm welding, improves the quality of the finished gas cylinder and production efficiency, and ensures product consistency.
