Description

Technical Field

[0001] The present invention belongs to the technical field of laser welding, and particularly relates to a welding device for manufacturing parts of civil aircraft. Background Art

[0002] Civil aircraft refer to aircraft other than those used for military, customs, and police flight missions. Parts refer to independent components that make up products such as machinery, electronics, electricity, and instrumentation, also called parts. Parts are the basic components that make up the entire product. Some parts are composed of two parts, and these two parts generally need to be connected by laser welding.

[0003] During the laser welding process, a laser beam with a high energy density acts on the surface of the workpiece. When the laser beam interacts with the material, a certain amount of fumes will be generated. There are wastes in these fumes, and these wastes need to be purified. Stripping is the most commonly used method during the purification process. However, with long-term use, the wastes will gradually block the stripping port. Generally, it needs to be dredged under external force. Since the blocked wastes are easily compressed to cause the stripping port to become larger or even damage the stripping port, affecting the subsequent stripping effect.

[0004] Therefore, a welding device for manufacturing parts of civil aircraft is proposed. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, the present invention provides a welding device for manufacturing parts of civil aircraft, aiming to solve the problems mentioned above.

[0006] An embodiment of the present invention provides a welding device for manufacturing parts of civil aircraft, including a laser welding box. A component picking and placing assembly is installed on the laser welding box, a protective cover is installed on the inner surface of the laser welding box, and a docking channel is installed at a horizontal side position near the protective cover on the outer surface of the laser welding box. One end of the docking channel is provided with a waste stripping member;

[0007] Further, the waste stripping member includes a tank body. A second protective cover and a first protective cover are respectively installed at the top and bottom of the tank body. A stripping member is installed in the tank body, and the stripping member includes a supporting tank, an adjusting tank, and a stripping area;

[0008] The supporting tank is installed in the tank body, the adjusting tank and the stripping area are installed in the supporting tank. The stripping area is used to strip the waste in the fumes, and the adjusting tank is used to adjust the density of the stripping area;

[0009] Further, an inlet channel and an outlet channel are respectively fixed on the outer surfaces of the first protective cover and the second protective cover;

[0010] A second supporting bracket is installed at the bottom of the first protective cover.

[0011] Furthermore, the supporting tank is installed at the bottom of the second shield, and a pair of introduction ends are reserved on the outer surface of the supporting tank, and the pair of introduction ends are arranged in a mirror image;

[0012] The two pairs of supporting ends are respectively on both sides of a pair of introduction ends. The inner surface of the supporting end is arched, and the center line of the supporting end is collinear with the center line of the supporting tank. There are a pair of peeling areas installed, and the pair of peeling areas are respectively in a pair of introduction ends, and the pair of peeling areas are respectively between a pair of supporting ends and are restricted.

[0013] Furthermore, the peeling area includes connecting blocks, horizontal ropes, restraining frames and vertical ropes;

[0014] There are a pair of connecting blocks installed. A number of horizontal ropes and vertical ropes are installed. A number of horizontal ropes are installed between the pair of connecting blocks. The number of horizontal ropes is in a loose state. A number of vertical ropes are installed in the restraining frames. The number of horizontal ropes and the number of vertical ropes form a grid shape for peeling waste materials.

[0015] Furthermore, the supporting end passes through the connecting groove from bottom to top. The connecting groove matches the connecting block. Docking grooves are reserved on the inner surface of the supporting tank and the bottom of the second shield. The pair of docking grooves are used to cooperate with the restraining frame.

[0016] Furthermore, the vertical ropes are on the side of the horizontal ropes, and both the vertical ropes and the horizontal ropes are tight ropes.

[0017] Furthermore, a number of restraining clamps are installed on the outer surfaces of the two vertical branches of the restraining frame. The number of restraining clamps is used to restrain the vertical ropes, so that the number of restraining clamps is arranged evenly, and the vertical ropes and the horizontal ropes maintain the formed grid evenly.

[0018] Furthermore, the component picking and placing assembly includes a stepping motor, a round table and a component welding cavity. The stepping motor is installed at the bottom of the laser welding box, and the output end of the stepping motor is fixedly connected to the bottom of the round table. Two pairs of component welding cavities are reserved at equal intervals axially on the top of the round table. An arc groove for the round table to rotate is reserved in the laser welding box. A part of the round table protrudes from the laser welding box. A fixture plate is installed in the component welding cavity. Screw holes for installing fixtures are reserved on the top of the fixture plate and the inner bottom of the component welding cavity. An electric push rod is installed in the round table, and the output end of the electric push rod is fixedly connected to the outer surface of the fixture plate. A switch is installed at a position on the top of the round table close to one side of the component welding cavity;

[0019] Furthermore, a first supporting frame is installed at the bottom of the laser welding box, and a box door is hinged on the outer surface of one side of the laser welding box. An XY-axis moving table is installed on the inner top of the laser welding box. A laser welding head is installed at the moving end of the XY-axis moving table. A protective cover is installed on the inner surface of the laser welding box.

[0020] The beneficial effects of the present invention are:

[0021] 1. When both the horizontal rope and the vertical rope are in a taut state, they can intercept waste materials. When the horizontal rope and the vertical rope are in a loose state, it helps to separate the intercepted waste materials. The horizontal rope and the vertical rope that can achieve the transformation between looseness and compaction can achieve a peeling effect, which is easy to remove waste materials, prevent waste material blockage, and prevent the shape of the formed peeling opening from changing after long-term operation.

[0022] 2. Rotate the adjustment tank, and the arched part presses against the horizontal rope to make the horizontal rope compact. The horizontal rope is originally in a horizontal state and cannot deviate during the rotation of the arched part. The distance between the horizontal ropes remains constant. The vertical rope is outside the horizontal rope, and the action of the arched part on the vertical rope is weak. After the horizontal rope and the vertical rope are compacted, equally spaced peeling openings can be formed to ensure the peeling effect.

[0023] 3. The installed restraint pliers restrain the vertical rope to make the vertical ropes evenly distributed, ensuring that the formed peeling openings are relatively uniform and ensuring the peeling effect.

[0024] Other features and advantages of the present invention will be described in the subsequent specification, and in part, will be obvious from the specification, or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained through the structures specifically pointed out in the specification and the drawings.

Detailed implementation manners

[0040] In order to make the objectives, technical solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0041] Refer to Figure 1 And Figure 2, including a laser welding box 1, on which a component picking and placing assembly 2 is installed. The component picking and placing assembly 2 includes a stepping motor 21, a round table 22 and a component welding cavity 24. The stepping motor 21 is installed at the bottom of the laser welding box 1, and the output end of the stepping motor 21 is fixedly connected to the bottom of the round table 22. Two pairs of component welding cavities 24 are reserved at equal intervals along the axial direction on the top of the round table 22. An arc groove 23 for the round table 22 to rotate is reserved in the laser welding box 1. A part of the round table 22 protrudes from the laser welding box 1. A fixture plate 25 is installed in the component welding cavity 24. Screw holes for installing fixtures are reserved on the top of the fixture plate 25 and the inner bottom of the component welding cavity 24. An electric push rod 26 is installed in the round table 22, and the output end of the electric push rod 26 is fixedly connected to the outer surface of the fixture plate 25. A switch 27 is installed at a position near one side of the component welding cavity 24 on the top of the round table 22;

[0042] During the laser welding of civil aircraft components, the fixtures adapted to the two parts of the components to be welded are respectively installed on the top of the fixture plate 25 and the inner bottom of the component welding cavity 24. The two fixtures are used to clamp and fix the two parts of the components respectively. The feeding and discharging operations of the round table 22 protruding from the laser welding box 1 are carried out on the outside of the laser welding box 1. As the stepping motor 21 drives the round table 22 to rotate, after the switch 27 is pressed by the laser welding box 1, the electric push rod 26 pulls the fixture plate 25 to move through its output end on one side, and the two parts of the components are butted and fitted together;

[0043] Refer to Figure 1 、 Figure 2 And Figure 3 , a support bracket 3 is installed at the bottom of the laser welding box 1, and a box door 4 is hinged to the outer surface of one side of the laser welding box 1. An XY-axis moving table 5 is installed at the top inside the laser welding box 1, a laser welding head 6 is installed at the moving end of the XY-axis moving table 5, a protective cover 7 is installed on the inner surface of the laser welding box 1, and a docking channel 8 is installed at a position near the horizontal side of the protective cover 7 on the outer surface of the laser welding box 1. A waste stripping part 9 is installed at one end of the docking channel 8.

[0044] When the butted and fitted components rotate to the specified position, the program in the laser welding box 1 controls the XY-axis moving table 5 to drive the laser welding head 6 to move along the set track. The laser emitted by the laser welding head 6 welds the joint of the two parts of the components. The waste generated during welding fills the laser welding box 1. As the round table 22 rotates again, the welded components move to the outside of the laser welding box 1, and workers can carry out discharging and feeding. Since the feeding and discharging do not require opening the box door 4, the fumes in the laser welding box 1 are difficult to leak out, which is convenient for the feeding and discharging operations and also avoids the waste leaking out and affecting the working environment. Under the diversion of the protective cover 7 and the docking channel 8, the fumes enter the waste stripping part 9.

[0045] Refer to Figure 4 、Figure 5 And Figure 6 , the waste stripping member 9 includes a can body 91, with a second shield 93 and a first shield 92 respectively installed at the top and bottom of the can body 91, and a stripping member 97 installed in the can body 91. The stripping member 97 includes a supporting can 971, an adjusting can 975 and a stripping area 976;

[0046] The supporting can 971 is installed in the can body 91, the adjusting can 975 and the stripping area 976 are installed in the supporting can 971. The stripping area 976 is used to strip the waste in the flue gas, and the adjusting can 975 is used to adjust the density of the stripping area 976. Adjustment is performed by using the adjusting can 975. Eyelets are reserved on the outer surface of the adjusting can 975, allowing the stripped flue gas to flow inward through the eyelets to achieve stripping.

[0047] Referring to Figure 4 , on the outer surfaces of the first shield 92 and the second shield 93, an inlet channel 95 and an outlet channel 96 are respectively fixed, ensuring the smooth introduction and extraction of the flue gas. The inlet channel 95 is connected to the joint of the docking channel 8;

[0048] A second supporting bracket 94 is installed at the bottom of the first shield 92.

[0049] Referring to Figure 6 , the supporting can 971 is installed at the bottom of the second shield 93. A pair of inlet ends 972 are reserved on the outer surface of the supporting can 971. The pair of inlet ends 972 are arranged in a mirror image, and the flue gas is introduced from the inlet ends 972;

[0050] Referring to Figure 7 , two pairs of supporting ends 973 are installed on the inner surface of the supporting can 971. The two pairs of supporting ends 973 are respectively on both sides of a pair of inlet ends 972. The inner surface of the supporting end 973 is arched, and the center line of the supporting end 973 is collinear with the center line of the supporting can 971. A pair of stripping areas 976 are installed. The pair of stripping areas 976 are respectively in a pair of inlet ends 972, and the pair of stripping areas 976 are respectively between a pair of supporting ends 973 and are restricted. The two pairs of supporting ends 973 are in contact with the adjusting can 975, so that after the flue gas is introduced into the inlet ends 972, it can only flow inward through the eyelets of the adjusting can 975.

[0051] Referring to Figure 8, the adjustment tank 975 is cylindrical. A pair of mirror-image arched parts 9751 and a pair of mirror-image smooth parts 9752 are arranged on the outer surface of the adjustment tank 975. The arched parts 9751 are used to press against the peeling area 976 to make the peeling area 976 tense. The smooth parts 9752 are used to press against the peeling area 976. The arched parts 9751 and the smooth parts 9752 of the adjustment tank 975 achieve the adjustment of the density of the peeling area 976, can achieve the effect of peeling off the waste in the flue gas, and can achieve the removal of the waste in a loose state, preventing the orifices of the peeling area 976 from changing. During the removal process, it is easy for the waste to pass through the orifices and cause the orifices to become larger, unable to meet the subsequent peeling of the waste in the flue gas;

[0052] The arched part 9751 of the adjustment tank 975 is in contact with the inner surface of the supporting end 973. Orifices for introducing flue gas are reserved on the arched part 9751. Orifices are reserved on the arched part 9751 because the arched part 9751 presses against the peeling area 976. The peeling area 976 is in a grid shape. During peeling, the flue gas must pass through the peeling area 976, and thus the flue gas must pass through the orifices on the arched part 9751.

[0053] Refer to Figure 8 、 Figure 9 And Figure 10 , the peeling area 976 includes connecting blocks 9761, horizontal ropes 9762, restraint frames 9763 and vertical ropes 9765; A pair of connecting blocks 9761 are arranged. A number of horizontal ropes 9762 and vertical ropes 9765 are arranged. A number of horizontal ropes 9762 are arranged between a pair of connecting blocks 9761. A number of horizontal ropes 9762 are in a loose state. A number of vertical ropes 9765 are arranged in the restraint frames 9763. A number of horizontal ropes 9762 and a number of vertical ropes 9765 form a grid shape for peeling off waste. A number of horizontal ropes 9762 and a number of vertical ropes 9765 are formed into a plate shape and have orifices for peeling off waste, achieving the peeling effect. After loosening, the orifices are not visible, which is beneficial for cleaning.

[0054] It is necessary to assemble the connecting blocks 9761 and the restraint frames 9763. The supporting end 973 passes through the connecting groove 974 from bottom to top. The connecting groove 974 matches the connecting blocks 9761. Docking grooves 9766 are reserved on the inner surface of the supporting tank 971 and the bottom of the second shield 93. A pair of docking grooves 9766 are used to cooperate with the restraint frames 9763.

[0055] The vertical rope 9765 is located on the side of the horizontal rope 9762. Both the vertical rope 9765 and the horizontal rope 9762 are tight ropes. The horizontal rope 9762 is on the side in contact with the arched part 9751. Even when the horizontal rope 9762 is affected by the rotation of the arched part 9751, it can still maintain a distributed balance. The vertical rope 9765 is not in contact with the arched part 9751, so it is less affected. In addition, the flue gas flows from outside to inside, exerting a pressing effect on the vertical rope 9765 and the horizontal rope 9762, causing the vertical rope 9765 and the horizontal rope 9762 to closely adhere to the arched part 9751, and then restraining the vertical rope 9765 and the horizontal rope 9762 again to maintain the peeling stability.

[0056] A number of restraint clamps 9764 are installed on the outer surfaces of the two vertical branches of the restraint frame 9763. The number of restraint clamps 9764 is used to restrain the vertical rope 9765, making the number of restraint clamps 9764 evenly arranged, and the vertical rope 9765 and the horizontal rope 9762 maintain a uniform grid structure.

[0057] The working principle of the present invention: Install the air extraction pump on the extraction channel 96. Using negative pressure, the flue gas generated by laser welding in the laser welding box 1 can enter the waste peeling part 9. The flue gas is introduced through the introduction channel 95 and extracted through the extraction channel 96. The waste in the flue gas is peeled in the can body 91. When the flue gas is introduced into the can body 91, it passes through the introduction end 972 and the peeling area 976 and is introduced into the supporting can 971, and then flows upward.

[0058] When the flue gas passes through the peeling area 976, the arched part 9751 of the adjusting tank 975 presses against the peeling area 976 and is in a state where it can support the peeling area 976. Both the horizontal rope 9762 and the vertical rope 9765 are in a taut state, making the grid formed by the horizontal rope 9762 and the vertical rope 9765 relatively firm, preventing the shape from changing, achieving the purpose of intercepting waste. Then, rotate the adjusting tank 975 so that the smooth part 9752 faces the peeling area 976, making the horizontal rope 9762 and the vertical rope 9765 in the peeling area 976 in a loose state. At this time, the waste on the horizontal rope 9762 and the vertical rope 9765 is easily shaken off, which helps to separate the intercepted waste. Subsequently, when the horizontal rope 9762 and the vertical rope 9765 are tightened again, it can prevent the formed peeling opening from becoming larger. Therefore, the horizontal rope 9762 and the vertical rope 9765 that can achieve the transformation between loose and tight can achieve the effect of peeling waste, which is easy to clean the waste, can also prevent waste blockage, and can also prevent the shape of the formed peeling opening from changing after long-term operation.

[0059] In addition, by rotating the adjustment tank 975, the composition and loosening of the stripping grille can be achieved, which is convenient for adjustment. When rotating the adjustment tank 975, the arched part 9751 presses against the horizontal rope 9762, tightening the horizontal rope 9762. The horizontal rope 9762 is originally in a horizontal state and cannot deviate during the rotation of the arched part 9751. The distance between the horizontal rope 9762 and the horizontal rope 9762 remains constant. The vertical rope 9765 is outside the horizontal rope 9762, and the arched part 9751 has a weak effect on the vertical rope 9765. After the horizontal rope 9762 and the vertical rope 9765 are tightened, stripping openings arranged at equal distances can be formed to ensure the stripping effect.

[0060] In addition, the installed restraint pliers 9764 restrain the vertical ropes 9765, enabling the vertical ropes 9765 to be evenly distributed, ensuring that the formed stripping openings are relatively uniform and ensuring the stripping effect.
