[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 7 As shown, this embodiment is a gas storage cylinder end cover processing auxiliary welding forming device, including a production line conveyor frame 1, and a cylinder jacket 4 is slidably sleeved on the top of the production line conveyor frame 1;

[0029] The cylinder jacket 4 includes a bottom sleeve 401 and a top sleeve 404. The inner walls of the bottom sleeve 401 and the top sleeve 404 are provided with inner rollers 405 and inflatable airbag cushions 406. A welding matching frame 2 is provided below the production line conveyor frame 1. After the semi-finished gas cylinder is produced and formed, it is transferred to the production line conveyor frame 1, and the cylinder jacket 4 cooperates with the production line conveyor frame 1 to transport it to the welding matching frame 2 area.

[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;

[0031] When the external device carries the valve seat and presses against the external valve 102 for docking, it pushes the external valve 102 to slide inside the frame until it docks with the valve port on the side of the sliding block 402, forming a temporary connected air path. And a spring damper is provided between the external valve 102 and the frame, which facilitates the external valve 102 to reset and disengage from the valve port on the sliding block 402 after losing the external force push.

[0032] A sliding block 402 is provided at the bottom of the bottom sleeve 401. Telescopic cylinders 403 connected to the top sleeve 404 are embedded in the cross-sections at both ends of the top of the bottom sleeve 401. The inner roller member 405 is sleeved in the middle of the inner walls of the bottom sleeve 401 and the top sleeve 404. Multiple groups of inner roller members 405 are arranged in an annular array. The expansion airbag pads 406 are embedded in the two side edges of the inner walls of the bottom sleeve 401 and the top sleeve 404. The two sets of expansion airbag pads 406 for feeding and discharging materials on the same side are spliced to form a ring.

[0033] Embodiment 2: This embodiment is an auxiliary welding and forming device for the end cover of an air storage cylinder, including a welding sleeve 3 slidably sleeved on the top of the welding fitting frame 2. An extrusion disc 303 and a welding clamp 304 are provided on the inner wall of the welding sleeve 3. An end cover feeding frame 6 is slidably sleeved on the outer wall of the welding fitting frame 2. A lifting cylinder frame 602 is provided on the top of the end cover feeding frame 6. And an adapter fixture 604 is provided on the inner wall of the lifting cylinder frame 602. A rotating mechanism 5 is provided in the middle of the welding fitting frame 2 between the frames of the production line conveyor 1.

[0034] Brackets 201 are symmetrically erected on the top of both ends of the welding fitting frame 2. 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 1 are recessed on the outer walls on both sides of the welding fitting frame 2. And an inner pushing cylinder 203 connected to the end cover feeding frame 6 is embedded in the transverse grooves.

[0035] A moving block 601 slidably sleeved in the transverse groove is provided at the bottom of the lifting cylinder frame 602. A limit frame drag 603 is sleeved on the outer wall of the top of the lifting cylinder frame 602. The adapter fixture 604 is slidably sleeved on the inner wall of the lifting cylinder frame 602. The limit frame drag 603 is not limited to the figure display and is specifically replaced according to the actual shape of the end cover.

[0036] The end cover semi-finished product is transported to the upper part of the end cover feeding frame 6 by the corresponding external transportation device. And the external transportation device is connected to the end cover feeding frame 6 through the limit frame drag 603, and transports the end cover semi-finished products one by one between multiple groups of adapter fixtures 604. The state of the end cover semi-finished product between the adapter fixtures 604 is adjusted by the robotic arm or related accessories on the external transportation device. The lifting cylinder frame 602 drives the end cover semi-finished product to slide down through the adapter fixture 604 until it is aligned with the air storage cylinder semi-finished product on the cylinder jacket 4. Then the inner pushing cylinder 203 drives the end cover feeding frame 6 to slide axially along the welding fitting frame 2 through the moving block 601 until the end cover semi-finished product is sleeved on the air storage cylinder semi-finished product.

[0037] Symmetrical clamping seats 301 are provided at the bottom of the welding sleeve 3. An annular groove is recessed on the inner wall of the side of the welding sleeve 3 close to the production line conveyor rack 1. The welding clamp 304 is slidably sleeved in the annular groove. A rotary motor connected to the welding clamp 304 is provided at the bottom of the welding sleeve 3. A metal ring is sleeved on the outer circumference of multiple groups of welding clamps 304 and is sleeved in the annular groove.

[0038] When the temporary communication air path is formed, under the control of the external air supply device, the telescopic cylinder 403 expands, and the telescopic cylinder 403 drives the top sleeve 404 to slide vertically upward until the bottom sleeve 401 and the top sleeve 404 move away from each other, facilitating the transfer of the semi-finished air storage cylinder to the bottom sleeve 401 by external equipment. The telescopic cylinder 403 drives the top sleeve 404 to slide downward and reset again. At the same time, multiple groups of expansion air cushions 406 are inflated synchronously;

[0039] After the top sleeve 404 slides downward and resets, the semi-finished air storage cylinder is clamped and limited in the middle of the cylinder jacket 4, and the outer wall of the semi-finished air storage cylinder is flexibly contacted and clamped by the airbag surface layer of the expansion air cushion 406, which is used to increase the clamping friction force on the semi-finished air storage cylinder and prevent surface damage caused by rigid clamping by the bottom sleeve 401 and the top sleeve 404 during transportation. It should be noted that a branch pipe connecting the expansion air cushion 406 and the telescopic cylinder 403 is provided inside the valve port, and a sub-pipe for connecting multiple groups of branch pipes is provided inside the valve seat, which can realize the regulated air supply inflation and deflation operation under the regulation of the external air supply device.

[0040] A valve seat connecting to the external air supply device is provided at the bottom of the side of the welding sleeve 3 close to the production line conveyor rack 1. Along with the approach of the welding sleeve 3, this group of valve seats is connected to the welding sleeve 3 through a regulating cylinder part. The welding sleeve 3 is driven by the propulsion cylinder 306 frame to approach the outside of the semi-finished end cover until the outer wall of the semi-finished end cover is embedded inside the welding sleeve 3. The propulsion cylinder 306 drives the extrusion disc 303 to slide axially until it contacts the outer wall of the semi-finished end cover. An electromagnet is embedded in the middle of the inner wall of the extrusion disc 303. When the electromagnet is energized, it generates a magnetic force to magnetically attract the semi-finished end cover on the extrusion disc 303. In this state, the end cover feeding rack 6 releases the clamping of this group of semi-finished end covers and resets to receive the next group of semi-finished end covers.

[0041] A cross-shaped bushing 305 is provided on the inner wall of the side of the welding sleeve 3 far from the production line conveyor rack 1. A propulsion cylinder 306 is sleeved on the outer side wall of the cross-shaped bushing 305. The extrusion disc 303 is located inside the welding sleeve 3 and is 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.
