Description

Technical Field

[0001] This invention belongs to the field of aviation parts manufacturing technology, specifically relating to an automated welding system and method for the production of aviation oxygen supports. Background Technology

[0002] Oxygen supports are components of aircraft oxygen supply systems, belonging to the category of ultra-thin-walled, irregularly shaped extruded parts. Aircraft oxygen supply systems refer to personal protective equipment (PPE) that ensures aircraft occupants can inhale sufficient oxygen to prevent hypoxia during high-altitude flight or emergency situations. They come in various forms depending on the number of occupants, flight range, service ceiling (cruising altitude), and mission nature, but generally consist of an oxygen source, control valves, regulators, indicating instruments, oxygen supply units, disconnectors, and oxygen masks. The oxygen source is primarily gaseous oxygen, followed by liquid oxygen; some large passenger aircraft also use solid oxygen sources. The oxygen regulator automatically adjusts the oxygen supply pressure, flow rate, and oxygen percentage according to changes in flight altitude, meeting the physiological needs of human respiration and surface pressurization. Commercial aircraft typically carry emergency oxygen supply systems. During normal flight, cabin pressurization prevents passenger hypoxia; if the cabin pressurization system fails, the emergency oxygen supply system ensures oxygen supply to all occupants and passengers for a short period while the aircraft descends.

[0003] Traditional welding systems for manufacturing aviation oxygen supports have several shortcomings. First, they cannot meet the welding and assembly requirements of modular aviation oxygen supports. Second, the walls of the assembled aviation oxygen supports are very thin and have poor toughness, making them prone to damage during use due to high stress. Third, they cannot hold oxygen generators. Fourth, they are not conducive to the storage and release of oxygen supply tubes for oxygen masks.

[0004] In view of this, the inventors aim to design an automated welding system and method for the production of aviation oxygen supports. Summary of the Invention

[0027] This invention also provides an automated welding method for the production of aviation oxygen supports, based on the aforementioned automated welding system for the production of aviation oxygen supports, comprising the following steps:

[0028] S1. Use the oxygen stent clamping assembly to position and clamp the oxygen stent profile as semi-finished product A.

[0029] S2. Using a punching assembly, multiple hollow areas consisting of hollow holes are punched on the main plate of the oxygen support profile to obtain semi-finished product B.

[0030] S3. Using the reinforcement plate loading assembly, several sets of reinforcement plates are snapped onto both sides of the main board. Each set of reinforcement plates is located in the blank area between two adjacent hollow areas, resulting in semi-finished product C.

[0031] S4. Using the slotting assembly, several sets of U-shaped slots are punched in the blank area of ​​the main board, and the board part inside the U-shaped slot is flipped upward to obtain the semi-finished product D.

[0032] S5. Using a bending assembly, the flipped plate is bent into an arc-shaped limiting plate for limiting the oxygen generator, resulting in a semi-finished product E.

[0033] S6. Use the reinforcing plate welding assembly to weld and lock the position of the reinforcing plate to the main board; use the winding machine feeding robot to abut and install the winding machine on the lower side of the main board, and use the winding machine welding assembly to weld and lock the position of the winding machine to the main board to obtain the finished product.

[0034] The beneficial effects of this invention are:

[0035] 1. This invention provides an automated welding system for the production of aviation oxygen supports. The various components work in concert: an oxygen support clamping assembly positions and clamps the oxygen support profile; a punching assembly punches multiple perforated areas on the main plate of the oxygen support profile; a reinforcing plate loading assembly attaches several sets of reinforcing plates to both sides of the main plate; a slit-opening assembly punches several sets of U-shaped slits in the blank area of ​​the main plate and flips the plate within the U-shaped slits upwards; a bending assembly bends the flipped plate into an arc-shaped limiting plate to restrict the oxygen generator; a reinforcing plate welding assembly welds and locks the reinforcing plate to the main plate; a winding machine loading robot abuts and installs the winding machine against the underside of the main plate, and a winding machine welding assembly welds and locks the winding machine to the main plate. This system automates a series of operations from clamping the oxygen support profile, punching, loading reinforcing plates, slit-opening, bending, welding reinforcing plates, loading the winding machine, to welding the winding machine, improving production efficiency, reducing labor costs, and ensuring product quality stability.

[0036] 2. The combined aviation oxygen support assembled by welding in this invention has high support strength and durability. By snapping reinforcing plates onto both sides of the main board and using the reinforcing plate welding assembly to weld and lock the reinforcing plates to the main board, the wall thickness and strength of the aviation oxygen support are enhanced, its poor toughness is improved, and damage caused by large stress during use is reduced.

[0037] 3. The combined aviation oxygen support assembled by welding in this invention provides an oxygen generator clamping function. The bending component bends the flipped plate into an arc-shaped limiting plate, which can be used to restrict the oxygen generator, thus solving the problem that traditional welded aviation oxygen supports cannot clamp the oxygen generator.

[0038] 4. The combined aviation oxygen support assembled by welding in this invention facilitates the storage and release of the oxygen supply tube. The winder is installed on the lower side of the main board and uses a suspension rope to wind and store the oxygen supply tube of the oxygen mask. The winding motor drives the rotating roller to achieve the winding, storage and release of the suspension rope, which solves the problem that the traditional welded aviation oxygen support is not conducive to the storage and release of the oxygen supply tube of the oxygen mask.

[0039] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0075] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] like Figure 1As shown, this embodiment provides an automated welding system for the production of aviation oxygen supports, including a controller 1 and connected to it an oxygen support clamping assembly 2, a punching assembly 3, a reinforcing plate loading assembly 4, a slotting assembly 5, a bending assembly 6, a reinforcing plate welding assembly 7, a winding machine loading robot 8, and a winding machine welding assembly 9.

[0077] like Figures 3-4 As shown, the oxygen support profile 10 includes a main board 101. One end of the main board 101 is provided with an anti-slip head 102. The main board 101 is symmetrically provided with a limiting protrusion 103 near the anti-slip head 102. The inner side of the limiting protrusion 103 and the other end of the main board 101 are symmetrically provided with a snap-fit ​​groove plate 104.

[0078] like Figure 7 As shown, the reinforcing plate 11 includes a straight plate portion 111, an arched portion 112 located in the middle, and locking plate portions 113 located at both ends thereon. The straight plate portion 111 is symmetrically provided with a plurality of spot welding through holes 114.

[0079] like Figures 12-14 As shown, the winder 12 includes a winder bracket 121, on which a winding motor 122 is mounted. The output end of the winding motor 122 is connected to a rotating roller 123, which is provided with movable support by the winder bracket 121. Several suspension ropes 124 that can pass through the inner cavity of the arched portion 112 are wound on the rotating roller 123. The outer ends of the suspension ropes 124 are equipped with end caps 125 that can be forcibly detached by tearing. The suspension ropes 124 are used to wind and store the oxygen mask supply tube. When the oxygen mask supply tube needs to be released, the rotating roller 123 is rotated by the winding motor 122, causing the suspension ropes 124 to detach from the end caps 125 and be wound and stored. Since the oxygen mask supply tube has no supporting carrier, it will fall quickly with the oxygen mask.

[0080] The oxygen stent clamping assembly 2 is used to position and clamp the oxygen stent profile 10. For example... Figure 15 As shown, the oxygen stent clamping assembly 2 includes a base frame 201. A vertical plate 202 is fixed to the upper side of one end of the base frame 201. A fixed clamping block 203 is installed on the upper side of the lower part of the vertical plate 202. A clamping push rod 204 is installed on the inner side of the upper part of the vertical plate 202. A movable clamping block 205 is installed on the movable end of the clamping push rod 204. A positioning block 206 is fixed to the upper side of the other end of the base frame 201. The fixed clamping block 203, the movable clamping block 205 and the positioning block 206 are each provided with a positioning groove that mates with the corresponding part of the oxygen stent profile 10.

[0081] The working principle of the oxygen support clamping assembly 2: The base frame 201 serves as the basic support structure, and the upright plate 202 is fixed to the upper side of one end of the base frame 201. A fixed clamping block 203 is installed on the upper side of the lower part of the upright plate 202, a clamping push rod 204 is installed on the inner side of the upper part of the upright plate 202, and a movable clamping block 205 is installed on the movable end of the clamping push rod 204. A positioning block 206 is fixed to the upper side of the other end of the base frame 201. Positioning grooves on the fixed clamping block 203, movable clamping block 205, and positioning block 206, which correspond to the parts of the oxygen support profile 10, are used to position and clamp the oxygen support profile 10. During operation, the clamping push rod 204 pushes the movable clamping block 205 towards the fixed clamping block 203, clamping the oxygen support profile 10 between them. Simultaneously, the positioning block 206 positions the profile from the other end, ensuring the stability of the profile during processing.

[0082] The punching assembly 3 is used to punch multiple hollow areas formed by hollow holes 105 on the motherboard 101. For example... Figure 16 As shown, the punching assembly 3 includes a first upper punching mechanism and a first lower bearing mechanism; the first upper punching mechanism includes a first linear guide pair 301, a first plate 302, an upper punching push rod 303, a second plate 304, and punch rods 305. The first plate 302 is mounted on the lower side of the slider of the first linear guide pair 301. The second plate 304 is supported by the upper punching push rod 303 on the first plate 302. Several punch rods 305 are mounted on the lower side of the second plate 304; the first lower bearing mechanism includes a second linear guide pair 302, a first plate 302, an upper punching push rod 303, a second plate 304, and punch rods 305. 6. The third plate 307, the lower punch push rod 308, the air pump 309, the fourth plate 310, and the pressure sleeve 311 are all mounted on the lower side of the slider of the second linear guide pair 306. The third plate 307 is supported by the lower punch push rod 308. The fourth plate 310 is supported by the third plate 307. Several pressure sleeves 311 are mounted on the upper side of the fourth plate 310. The air pump 309 is mounted on the third plate 307. The air pump 309 is connected to the inner cavity of each pressure sleeve 311 through a hose and the built-in channel of the fourth plate 310.

[0083] Working principle of punching component 3:

[0084] First upper punching mechanism: The slider of the first linear guide pair 301 drives the first plate 302 to move, the upper punching push rod 303 supports the second plate 304, and the punch rod 305 installed on the lower side of the second plate 304 is used for punching. During operation, the first linear guide pair 301 adjusts the horizontal position of the punch rod 305, and the upper punching push rod 303 pushes the second plate 304 downward, so that the punch rod 305 punches the main plate 101.

[0085] The first lower pressure-bearing mechanism: The slider of the second linear guide pair 306 drives the third plate 307 to move, and the lower punching push rod 308 supports the fourth plate 310. The pressure-bearing sleeve 311 installed on the upper side of the fourth plate 310 is used to withstand the impact force of the punch rod 305. The air pump 309 is connected to the inner cavity of each pressure-bearing sleeve 311 through a hose and the built-in channel of the fourth plate 310, which can provide a certain air pressure assistance during punching. During operation, the second linear guide pair 306 adjusts the position of the pressure-bearing sleeve 311 so that it corresponds to the punch rod 305. The lower punching push rod 308 pushes the fourth plate 310 to move upward, so that the pressure-bearing sleeve 311 contacts the lower side of the main plate 101 and withstands the impact of the punch rod 305, thus completing the punching operation and forming multiple hollow areas composed of hollow holes 105 on the main plate 101.

[0086] The reinforcing plate mounting assembly 4 is used to snap-fit ​​several sets of reinforcing plates 11 onto both sides of the main board 101, with each set of reinforcing plates 11 located in the blank area between two adjacent cutout areas. For example... Figure 17 As shown, the reinforcing plate loading assembly 4 includes two reinforcing plate loading mechanisms symmetrically distributed vertically. Each reinforcing plate loading mechanism includes a third linear guide pair 401, a fifth plate 402, a first lifting push rod 403, and a suction block 404. The fifth plate 402 is mounted on the outer side of the slider of the third linear guide pair 401. The fifth plate 402 supports the suction block 404 through the first lifting push rod 403. The suction block 404 has an adsorption surface that cooperates with the arched part 112 in the reinforcing plate 11.

[0087] Working principle of the reinforcing plate loading assembly 4: The reinforcing plate loading assembly 4 includes two reinforcing plate loading mechanisms symmetrically distributed vertically. The slider of the third linear guide pair 401 drives the fifth plate 402 to move. The first lifting push rod 403 supports the suction block 404, which has an adsorption surface that cooperates with the arched part 112 in the reinforcing plate 11. During operation, the third linear guide pair 401 adjusts the horizontal position of the suction block 404 to align it with the reinforcing plate 11. The first lifting push rod 403 pushes the suction block 404 downward, and the adsorption surface adsorbs the arched part 112 of the reinforcing plate 11. Then, the first lifting push rod 403 lifts the suction block 404, causing the reinforcing plate 11 to rise. The third linear guide pair 401 then moves the reinforcing plate 11 to the corresponding position on the main plate 101. The first lifting push rod 403 descends to snap the reinforcing plate 11 onto both sides of the main plate 101. Each set of reinforcing plates 11 is located in the blank area between two adjacent hollow areas.

[0088] The slotting assembly 5 is used to stamp several sets of U-shaped slots 106 in the blank area of ​​the main board 101, and to flip the board portion within the U-shaped slots 106 upwards. For example... Figure 18As shown, the slit assembly 5 includes a second upper punching mechanism and a second lower bearing mechanism; the second upper punching mechanism includes a fourth linear guide pair 501, a sixth plate 502, a second lifting push rod 503, a seventh plate 504, and U-shaped slit punches 505. The sixth plate 502 is mounted on the lower side of the slider of the fourth linear guide pair 501, and the seventh plate 504 is supported by the second lifting push rod 503. Two rows of U-shaped slit punches 505 are symmetrically mounted on the lower side of the seventh plate 504; the second lower bearing mechanism includes a fifth linear guide pair 506 and an eighth plate 507.
