[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention cooperates with the welding assembly, the blowing assembly and the drainage assembly. During the welding process, argon is continuously blown on one side and inhaled on the other side, forming a directional laminar protective gas flow field around the welding area. This can not only isolate the air to avoid affecting the welding quality, but also guide the argon to flow smoothly, preventing the air flow from being turbulent or air being drawn in due to simple blowing, thereby further improving the argon protection range and stability. After the welding is completed, the fixing assembly, the auxiliary assembly and the cleaning assembly cooperate.

[0018] 2. The present invention starts spraying argon before the welding head is operated through the cooperation of a bidirectional screw and a slide as well as airbags 2 and 3, thereby forming an inert gas protective layer in the welding area in advance, isolating the air, preventing the aluminum alloy from oxidizing at high temperatures, and avoiding welding defects such as pores and cracks. At the same time, it can also ensure that the argon is uninterrupted during the entire welding and resetting process; the fan is also operated to cooperate with the sprayed argon to form a directional airflow, thereby avoiding ineffective escape of argon, ensuring that the argon flows fully through the welding area, and ensuring welding quality. Similarly, whether it is welding or resetting, the cooperation of gears 5, 3 and 4 can achieve continuous flow of argon in the same direction, thereby avoiding exposure of the welding area to the air due to airflow interruption or disturbance.

[0019] 3. The present invention uses a paddle plate in conjunction with a paddle roller, a circular ring, and a one-way shaft structure to drive the operation of the rotating rod 1 and the rotating rod 2 after the welding station is switched, so as to store energy for subsequent cleaning actions when the station is automatically switched. Then, in conjunction with the cleaning component, the surface of the aluminum alloy pipe to be welded can be evenly coated with a detergent to remove oil stains, thereby avoiding defects such as pores and slag inclusions during welding. In addition, two adsorption plates can be used in conjunction with a penetrating brush to directly sweep away loose impurities during the left and right movement, ensuring that the area to be welded is thoroughly treated before welding.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1, as Figure 1 and Figure 2 As shown, a welding device for processing aluminum alloy doors and windows includes a processing table 1, a fixing component 2 is rotatably connected to the middle part of the upper end of the processing table 1, a welding component 3 is fixedly connected to the right side of the upper end of the processing table 1, a blowing component 6 is fixedly connected to the upper end of the processing table 1 in front of the welding component 3, and a drainage component 7 is fixedly connected to the upper end of the processing table 1 behind the welding component 3. An auxiliary component 5 is arranged on the left side of the upper end of the processing table 1, and a cleaning component 4 is arranged on the upper part of the auxiliary component 5.

[0034] In the production process of aluminum alloy doors and windows, especially for doors and windows used in laboratories with high requirements for air tightness, it is necessary to ensure the sealing of the connection between the frames by welding. When welding aluminum alloy windows, the aluminum alloy tubes to be welded are placed and fixed in turn through the cooperation of the fixing component 2, and then the welding component 3 is activated to weld the two aluminum alloy tubes to be welded. In the welding process using the welding component 3, through the cooperation with the blowing component 6, argon gas is continuously blown into the welding area to be welded from the front side of the welding component 3 before welding begins, creating an inert gas atmosphere. At the same time, the blowing continues during and after the welding process. Similarly, during the welding process, the drainage component 7 cooperates to continuously guide the argon gas to flow backward from the rear side of the welding component 3, so that the argon gas flows backward after passing through the welding area, so that the argon gas flows smoothly and directionally through the entire welding area.

[0035] After one welding process, the driving device in the prior art cooperates with the fixing component 2 to drive the entire aluminum alloy tube to be welded to rotate a certain angle, so that the part to be welded is rotated to the bottom of the welding component 3. During the rotation of the fixing component 2, it can also cooperate with the auxiliary component 5 and the cleaning component 4 to achieve degreasing and cleaning of the aluminum alloy area to be welded, ensuring that there will be no contamination by impurities such as oil during the welding process.

[0036] During the operation of this embodiment, through the cooperation of the welding component 3, the blowing component 6 and the drainage component 7, during the welding process, argon is continuously blown on one side and inhaled on the other side to form a directional laminar protective gas flow field around the welding area, which can not only isolate the air to avoid affecting the welding quality, but also guide the argon to flow smoothly, prevent the air flow from being turbulent or air being drawn in due to simple blowing, and further improve the argon protection range and stability. After the welding is completed, the fixing component 2, the auxiliary component 5 and the cleaning component 4 cooperate. After the welding station is changed, the auxiliary component 5 is used in conjunction with the cleaning component 4 to clean the welding area to be cleaned, so as to avoid the oil and impurities carried on the surface of the aluminum alloy tube affecting the welding quality.

[0037] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effect of continuously and evenly outputting argon gas to protect the welding area during the welding process.

[0038] See Figure 3 The fixing assembly 2 includes a rotating shaft 21 rotatably connected to the upper end of the processing table 1, and five dial plates 22 are arranged in a circular array on the lower outer surface of the rotating shaft 21. Five fixing rods 23 are arranged in a circular array on the upper outer surface of the rotating shaft 21. The upper ends of the five fixing rods 23 are fixedly connected to two hydraulic cylinders 25, and the upper ends of the two hydraulic cylinders 25 on the same side are commonly fixedly connected to a pressure plate 24.

[0039] The rotating shaft 21 is connected to the driving device in the prior art. The driving device cooperates with the rotating shaft 21 to drive the rotating shaft 21 to rotate 72°, then pause and repeat the above rotation method until the welding is completed.

[0040] Similarly, in the process of preparing for welding, the aluminum alloy tubes to be welded are placed on the upper end of the fixing rod 23 in sequence, and driven by two adapted hydraulic cylinders 25, the aluminum alloy tubes to be welded are clamped and fixed in cooperation with the pressing plate 24.

[0041] See Figure 4 and Figure 5 The welding assembly 3 includes a motor 36 fixedly connected to the upper end of the processing table 1, and the outer surface of the output end of the motor 36 is fixedly connected to the gear 2 37, and the outer surface of the output end of the motor 36 is transmission-connected to the roller 1 33, and the outer surface of the roller 1 33 is fixedly connected to the gear 1 34. The gear 1 34 and the gear 2 37 are jointly meshed with an outer gear ring 32, and the inner surface of the outer gear ring 32 is slidably connected to the guide ring 31, and the front side of the guide ring 31 is fixedly connected to the support plate 38, and the upper end of the support plate 38 is fixedly connected to the welding head 35.

[0042] The above-mentioned welding head 35 is a conventional design in the prior art. The aluminum alloy tube can be welded through the operation of the welding head 35. The specific structural composition and working principle of the welding head 35 will not be elaborated in detail in this scheme. The welding head 35 is connected to the control terminal in the prior art, and the on and off of the welding head 35 can be directly controlled.

[0043] The outer surface of the output end of the motor 36 is connected to the roller 1 33 via a pulley in the prior art.

[0044] After the aluminum alloy tube to be welded is fixed, the welding head 35 and the motor 36 are activated, and then the motor 36 drives the roller 1 33 to rotate at the same time, and then the gear 1 34 and the gear 2 37 are driven to rotate respectively, and the gear 1 34 and the gear 2 37 work together to drive the outer gear ring 32 to rotate one circle along the outer surface of the guide ring 31. During the rotation of the outer gear ring 32, the support plate 38 and the welding head 35 will be driven to move in the same direction, and then the welding head 35 will approach the position to be welded to weld the two aluminum alloy tubes. After the outer gear ring 32 drives the support plate 38 and the welding head 35 to rotate one circle around the guide ring 31, the output end of the motor 36 is reversed, and then the outer gear ring 32 drives the support plate 38 and the welding head 35 to reverse and reset along the outer surface of the guide ring 31.

[0045] See Figure 8 The blowing assembly 6 includes a bidirectional screw rod 61 that is transmission-connected to the outer surface of the rotating roller 33. A slide plate 62 is provided in the middle of the outer surface of the bidirectional screw rod 61. The slide plate 62 is slidingly connected to the upper end of the processing table 1. A guide rod 63 is fixedly connected to the front side of the upper end of the processing table 1. The outer surface of the guide rod 63 is slidingly connected to the slide plate 62.

[0046] The above-mentioned bidirectional screw rod 61 and roller 1 33 are connected by a pulley in the prior art, and the radius of the pulley fixedly connected to the outer surface of the bidirectional screw rod 61 is smaller than the radius of the pulley fixedly connected to the outer surface of roller 1 33. In the process of roller 1 33 driving the bidirectional screw rod 61 to rotate, the rotation speed of the bidirectional screw rod 61 is faster than that of roller 1 33.

[0047] When the motor 36 is excited to prepare for welding, the roller 1 33 cooperates with the bidirectional screw 61 to make the bidirectional screw 61 rotate continuously. At this time, the guide rod 63 limits the slide 62, and during the rotation of the bidirectional screw 61, the slide 62 moves back and forth along the axis of the bidirectional screw 61.

[0048] See Figure 8 The front side of the upper end of the processing table 1 is fixedly connected to the second vertical plate 641, and the rear end of the second vertical plate 641 and the front end of the slide 62 are fixedly connected to the second airbag 64. The rear side of the upper end of the processing table 1 is fixedly connected to the third vertical plate 651, and the front end of the third vertical plate 651 and the rear end of the slide 62 are fixedly connected to the third airbag 65. The outer surface of the third airbag 65 and the outer surface of the second airbag 64 are fixedly connected to the second hose 68. The end of the second hose 68 away from the third airbag 65 is fixedly connected to the hard tube 67. The hard tube 67 is fixedly connected to the upper end of the support plate 38, and the end of the hard tube 67 away from the second hose 68 is fixedly connected to the nozzle 66.

[0049] The outer surface of the nozzle 66 is provided with a plurality of nozzles.

[0050] The connection between the second hose 68 and the third airbag 65 and the second airbag 64 is provided with a one-way valve, so that the gas inside the second airbag 64 or the third airbag 65 can only flow to the inner surface of the second hose 68 through the one-way valve, and the gas inside the second hose 68 cannot flow into the interior of the second airbag 64 or the third airbag 65;

[0051] Similarly, the above-mentioned airbag three 65 and airbag two 64 are respectively connected to the argon source in the prior art, and a one-way valve is also provided at the connection point, so that the argon in the prior art flows through the one-way valve to the inside of airbag two 64 or airbag three 65, and cannot flow in the opposite direction.

[0052] When the slide plate 62 moves forward along the axis of the bidirectional screw 61, it cooperates with the second vertical plate 641 to continuously squeeze the second airbag 64. At this time, the argon gas inside the second airbag 64 enters the second hose 68. Then, the argon gas enters the hard tube 67 through the second hose 68 and is ejected from the multiple nozzles on the outer surface of the nozzle 66 to the area to be welded.

[0053] While the slide plate 62 squeezes the airbag 2 64 , the airbag 3 65 is stretched by cooperating with the vertical plate 3 651 . At this time, the argon gas in the argon gas source enters the interior of the airbag 3 65 .

[0054] When the slide 62 moves backward along the axis of the bidirectional screw 61, the airbag 3 65 is squeezed and the airbag 2 64 is stretched. The argon gas inside the airbag 3 65 enters the inside of the hose 2 68 and is ejected through the hard tube 67, the nozzle 66 and several nozzles. The argon gas in the argon gas source enters the inside of the airbag 2 64.

[0055] The above process is repeated while the slide plate 62 moves back and forth along the axis of the bidirectional screw rod 61.

[0056] Furthermore, since the rotation speed of the bidirectional screw 61 is faster than that of the roller 1 33 , when the outer gear ring 32 drives the welding head 35 to start rotating, the nozzle 66 has already sprayed argon gas toward the welding area.

[0057] During the welding and resetting process of the welding head 35 rotating one circle along the guide ring 31, the welding area is always filled with argon gas through the cooperation between the airbag 3 65 and the airbag 2 64 , the hose 2 68 , the hard pipe 67 and the nozzle 66 .

[0058] See Figure 6 and Figure 7 The drainage component 7 includes a fixed plate 75 fixedly connected to the upper end of the processing table 1. The output end of the motor 36 passes through the front end of the fixed plate 75 and extends to the rear end. The rear end of the outer surface of the motor 36 is fixedly connected to a gear three 71. The outer surface of the gear three 71 is meshed with a gear four 72. The upper part of the outer surface of the gear three 71 is meshed with a gear five 73. The upper part of the outer surface of the gear five 73 is meshed with a gear six 74. The rear end of the gear six 74 is fixedly connected to a roller three 76. The outer surface of the roller three 76 is transmission-connected to a fan 77.

[0059] The three rollers 76 and the fan 77 are connected to each other through a pulley in the prior art.

[0060] When the motor 36 is running and the welding head 35 is ready for welding, the nozzle 66 has been continuously blowing argon gas toward the welding area. Then, when the motor 36 rotates, it drives the gear three 71 to rotate. Then, the gear three 71 cooperates with the operation of the gear five 73, the gear six 74 and the roller three 76 to make the fan 77 rotate continuously, thereby guiding the argon gas blown out of the nozzle 66 on the front side of the welding head 35 to flow backward, so that the argon gas blown out of the nozzle 66 can pass through the welding area smoothly, which can more effectively utilize the argon gas and avoid ineffective escape. At the same time, the fan 77 rotates continuously to inhale air, and can also cooperate with the flowing argon gas to timely drain away the smoke and spatter generated during the welding process, keeping the welding area clean.

[0061] See Figure 7The rear end of the fixed plate 75 is fixedly connected to the limiting groove 2 78, and the front end of the gear 5 73 is fixedly connected to the roller 2 731. The outer surface of the roller 2 731 is rotatably connected to the limiting ring 781, and the outer surface of the limiting ring 781 is slidably connected to the inner surface of the limiting groove 2 78.

[0062] During the forward rotation of the output end of the motor 36, the gear 3 71 is driven to rotate, and then the gear 3 71 is meshed with the outer surface of the gear 5 73. The rotation of the gear 3 71 causes the gear 5 73 and the gear 6 74 to rotate, thereby rotating the fan 77.

[0063] During the reversal process of the output end of the motor 36, the gear three 71 reverses and pushes the gear five 73 to drive the roller two 731 and the limiting ring 781 to slide along the inner surface of the limiting groove two 78 toward the side close to the fan 77. During the sliding process of the gear five 73, the roller two 731 and the limiting ring 781 along the inner surface of the limiting groove two 78, the gear five 73 gradually disengages from the outer surface of the gear three 71 and begins to engage with the outer surface of the gear four 72. When the gear five 73, the roller two 731 and the limiting ring 781 slide to the left side of the inner surface of the limiting groove two 78, the outer surface of the gear five 73 engages with the gear four 72, and the gear five 73 is no longer in contact with the gear three 71.

[0064] When the output end of the motor 36 is reversed, the gear three 71, the gear four 72, and the gear five 73 and other structures cooperate to make the fan 77 continue to rotate to inhale air, thereby achieving that whether during the welding process or when resetting, the fan 77 is always in the inhalation state, so that the argon gas ejected from the nozzle 66 flows evenly through the welding area.

[0065] Therefore, this solution starts to spray argon before the welding head 35 operates through the cooperation of the bidirectional screw 61 and the slide 62 as well as the airbag 2 64 and the airbag 3 65, so as to form an inert gas protection layer in the welding area in advance, isolate the air, prevent the aluminum alloy from oxidizing at high temperature, and avoid welding defects such as pores and cracks. At the same time, it can also ensure that the argon is uninterrupted during the entire welding and resetting process; the fan 77 is also operated to cooperate with the sprayed argon to form a directional airflow to avoid the ineffective escape of argon, ensure that the argon flows fully through the welding area, and ensure the welding quality. Similarly, whether it is welding or resetting, the gear five 73 is coordinated with the gear three 71 and the gear four 72 to achieve continuous flow of argon in the same direction, avoiding the welding area from being exposed to the air due to air flow interruption or disturbance.

[0066] Embodiment 3: Based on embodiments 1 and 2, this embodiment aims to achieve the effect of storing energy for subsequent cleaning when switching welding stations and cleaning the surface of the aluminum alloy tube to be welded after switching stations.

[0067] See Figure 9 and Figure 10The auxiliary component 5 includes a circular ring 51 rotatably connected to the upper end of the processing table 1, and ten rollers 52 are arranged in an annular array on the outer surface of the circular ring 51. The outer surface of one roller 52 is in close contact with the adapted dial plate 22. A one-way shaft 53 is fixedly connected to the inner surface of the circular ring 51, and a round box 58 is rotatably connected to the inner surface of the one-way shaft 53. A torsion spring 571 is provided on the inner surface of the round box 58, and a circular plate 57 is fixedly connected to the upper end of the circular box 58. A speed change mechanism 54 is provided on the upper end of the circular plate 57, and a rotating rod 55 is provided on the upper end of the speed change mechanism 54. The upper end of the rotating rod 55 is fixedly connected to the rotating rod 2 56, and a circular roller 561 is fixedly connected to one side of the upper end of the rotating rod 2 56.

[0068] The one-way shaft 53 is a conventional design in the prior art. When the ring 51 rotates clockwise, the one-way shaft 53 and the round box 58 are driven to rotate clockwise in the same direction. When the round box 58 is driven to rotate counterclockwise, the one-way shaft 53 prevents the ring 51 and the ten rollers 52 from rotating.

[0069] A one-way shaft 2 is provided between the round box 58 and the circular plate 57. Through the cooperation of the one-way shaft 2, when the round box 58 rotates clockwise, the circular plate 57 does not rotate. When the round box 58 rotates counterclockwise, the one-way shaft 2 and the circular plate 57 rotate simultaneously.

[0070] The above-mentioned torsion spring 571 is of conventional design in the prior art. The central fixed end of the torsion spring 571 is fixedly connected to the upper end of the processing table 1 through the middle of the bottom wall of the inner surface of the round box 58, and the outer ring movable end of the torsion spring 571 is fixedly connected to one side of the inner surface of the round box 58.

[0071] The above-mentioned speed change mechanism 54 is a conventional setting in the prior art. When the circular plate 57 rotates a certain angle, the speed change mechanism 54 can cooperate with the rotating rod 55 to rotate a full circle.

[0072] After the outer gear ring 32 and the welding head 35 have run one circle along the guide ring 31 and reset, one welding is completed, and then the drive device in the prior art drives the rotating shaft 21 to rotate 72 degrees counterclockwise to rotate the area to be welded to the bottom of the welding head 35;

[0073] When the rotating shaft 21 rotates, the five dial plates 22 are driven to rotate simultaneously. Then, when the dial plates 22 rotate, the dial rollers 52 are moved. Then, when the dial rollers 52 are moved, the ring 51 and the ten dial rollers 52 rotate clockwise simultaneously.

[0074] During the clockwise rotation of the ring 51, the one-way shaft 1 53 cooperates to drive the round box 58 to rotate clockwise. When the round box 58 rotates clockwise, the outer ring movable end of the torsion spring 571 moves simultaneously, and the torsion spring 571 continuously stores energy.

[0075] When the rotating shaft 21 rotates 72 degrees, the rotating shaft 21 stops rotating and is ready for welding. At this time, the paddle 22 is just separated from the paddle roller 52, and the other paddle 22 is tightly attached to the paddle roller 52 again. At this time, the energy storage of the torsion spring 571 ends.

[0076] Then there is no external force to push the torsion spring 571 to tighten, and the torsion spring 571 causes the round box 58 to rotate counterclockwise through the restoring force. When the round box 58 rotates counterclockwise, the one-way shaft 1 53 and the ring 51 do not rotate. At this time, the cooperation of the one-way shaft 2 causes the circular plate 57 to rotate a certain angle.

[0077] Then, after the circular plate 57 rotates a certain angle, the speed change mechanism 54 cooperates to operate so that the rotating rod 1 55 and the rotating rod 2 56 rotate one circle at the same time.

[0078] Furthermore, each time the rotating shaft 21 rotates, the cooperation between the dial plate 22 and the dial roller 52 can ensure that the first rotating rod 55 and the second rotating rod 56 are driven to rotate one circle only after the rotating shaft 21 stops rotating.

[0079] See Figure 11 The cleaning component 4 includes a limiting groove 41 that is slidably connected to the outer surface of the round roller 561, a round rod 42 is fixedly connected to the middle of the right end of the limiting groove 41, and an adsorption plate 46 is symmetrically fixedly connected to the right end of the round rod 42. A number of penetration brushes 461 are fixedly connected to one end of the two adsorption plates 46 close to each other, a round rod 2 43 is fixedly connected to the left end of the limiting groove 41, a push plate 44 is fixedly connected to the left end of the round rod 2 43, and the push plate 44 is slidably connected to the upper end of the processing table 1, and an airbag 45 is fixedly connected to the left end of the push plate 44. A vertical plate 451 is fixedly connected to the left side of the outer surface of the airbag 45, and a hose 47 is fixedly connected to the outer surface of the airbag 45. The end of the hose 47 away from the airbag 45 is fixedly connected to the two adsorption plates 46 respectively.

[0080] The airbag 1 45 is connected to an external aluminum alloy cleaning agent source, and a one-way valve is provided at the connection point so that the cleaning agent can only enter the airbag 1 45 through the one-way valve;

[0081] Similarly, a one-way valve is provided at the connection between the hose 1 47 and the airbag 1 45 , so that the cleaning agent inside the airbag 1 45 can flow into the hose 1 47 through the one-way valve and cannot flow in the opposite direction.

[0082] When the rotating rod 56 rotates one circle, the round roller 561 is driven to rotate around the axis of the rotating rod 56. Then, when the round roller 561 rotates, the round roller 561 rotates one circle around the axis of the rotating rod 56 through the cooperation of the limiting groove 1 41, thereby causing the limiting groove 1 41, the round rod 1 42 and the round rod 2 43 to move left and right once.

[0083] As the limiting groove 41 drives the round rod 42 to move to the right, the two adsorption plates 46 are pushed to the right. As the two adsorption plates 46 move to the right, a number of penetrating brushes 461 are close to the area of ​​the aluminum alloy tube to be welded. Through the cooperation of the penetrating brushes 461, the aluminum alloy cleaner adsorbed by the adsorption plate 46 is squeezed out through the penetrating brushes 461 and evenly applied to the surfaces of the two aluminum alloy tubes to be welded.

[0084] When the limiting groove 1 41 drives the round rod 1 42 and the round rod 2 43 to move to the left, the round rod 2 43 pushes the push plate 44 to the left, and then the air bag 1 45 is squeezed through the cooperation of the vertical plate 1 451. At this time, the cleaning agent inside the air bag 1 45 enters the two adsorption plates 46 and the multiple penetration brushes 461 respectively through the hose 1 47. When the multiple penetration brushes 461 pass through the aluminum alloy tube to be welded, the cleaning agent inside the adsorption plate 46 and the multiple penetration brushes 461 will be squeezed onto the surface of the aluminum alloy tube.

[0085] When the limiting groove 1 41 drives the round rod 2 43 to move to the right, it drives the push plate 44 to move to the right at the same time, thereby stretching the airbag 1 45 and replenishing the cleaning agent into the airbag 1 45.

[0086] When the two adsorption plates 46 cooperate with the plurality of penetration brushes 461 to move left and right once, the cleaning agent can be applied to the surface of the aluminum alloy tube to be welded to remove surface oil stains, and impurities on the surface of the aluminum alloy tube can be swept away, thereby further improving the quality of aluminum alloy welding.

[0087] Therefore, this solution uses the dial plate 22 to cooperate with the dial roller 52, the ring 51, the one-way shaft 1 53 and other structures to drive the operation of the rotating rod 1 55 and the rotating rod 2 56 and other structures after the welding station is switched, so as to realize the automatic switching of the sub-stations and store energy for the subsequent cleaning action. Then, in conjunction with the cleaning component 4, it is further achieved that the surface of the aluminum alloy pipe to be welded is evenly coated with a detergent to remove oil stains, thereby avoiding defects such as pores and slag inclusions during welding. In addition, the two adsorption plates 46 can cooperate with the penetration brush 461 to directly sweep away loose impurities during the left and right movement, thereby ensuring that the area to be welded is thoroughly treated before welding.
