Description

Technical Field

[0001] The present invention belongs to the technical field of welding machinery and relates to a welding equipment for fixed-wing manned aircraft. Background Art

[0002] A fixed-wing manned aircraft is an aircraft that uses fixed wings to generate lift and fly within the atmosphere. Its main characteristics include parameters such as the wing position and sweep angle being fixed. It has advantages such as high speed, high maneuverability, safety, and comfort. With its unique performance and broad application prospects, fixed-wing manned aircraft occupy an important position in the aviation field. With the progress of technology and the growth of market demand, fixed-wing manned aircraft will play an important role in more fields in the future.

[0003] Engine, fuel distribution pipes, ducts, etc. are pipe components of fixed-wing manned aircraft. The quality of welding such pipes seriously affects the quality of fixed-wing manned aircraft.

[0004] Chinese Patent with Application No. 202310514739.3 discloses a pipe welding device, which includes a base. A fixing device is arranged on the base. The fixing device includes two groups of support frame mechanisms. Both groups of support frame mechanisms are fixedly installed on the base, and a fixing component movably installed inside the support frame mechanism. The fixing component includes two groups of side plates. Driving the first gear to move radially makes the four groups of clamps move towards the center until the receiving shaft slides to the outermost end of the inclined chute and cannot move. At this time, the pipe is clamped between the four groups of clamps, thereby realizing the fixation of the clamps. When it is necessary to disassemble the pipe, drive the first gear to return to the initial position radially, and the four groups of clamps release the fixation of the pipe.

[0005] In the above-mentioned prior art, the following problems exist: First, when installing the pipe to be welded, the welding position of the pipe to be welded is very likely to have oil stains or other dirt. If the dirt is not cleaned and welded directly, the welding will be insecure. At the same time, cleaning work needs to be done before welding, which affects the welding efficiency. Second, in the above-mentioned prior art, when positioning the pipe, a baffle is used for positioning. Since the baffle has a certain thickness, it is inevitable that the gap between the welding surfaces of the two pipes during welding is large, ultimately affecting the welding quality.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-9 shown, the technical solution adopted by the present invention is as follows: A fixed-wing manned aircraft welding equipment. It includes a base 1, and a first sleeve 2 with its axis arranged horizontally is fixedly installed on the upper end surface of the base 1. A fixed shaft 9 with its axis parallel to the axis of the first sleeve 2 is fixedly installed on the side wall of the first sleeve 2. A second sleeve 3 parallel to the axis of the first sleeve 2 is rotatably installed on the fixed shaft 9. The first sleeve 2 and the second sleeve 3 are the same in shape and size. The pipe fittings 6 to be welded are respectively installed in the first sleeve 2 and the second sleeve 3.

[0032] Sponge pads 7 are installed on the end faces of the first sleeve 2 and the second sleeve 3 that are close to each other.

[0033] During initial installation, the first sleeve 2 and the second sleeve 3 are not coaxial. The pipe fittings 6 are respectively installed in the first sleeve 2 and the second sleeve 3. Before welding, the second sleeve 3 needs to be rotated to a position coaxial with the first sleeve 2. When the second sleeve 3 rotates around the fixed shaft 9, the second sleeve 3 drives the pipe fitting 6 installed in the second sleeve 3 to rotate together. The sponge pad 7 installed on the second sleeve 3 can rub against the end face of the pipe fitting 6 installed in the first sleeve 2 that is close to the second sleeve 3, so as to clean the welding surface of the pipe fitting 6 installed in the first sleeve 2. Similarly, when the second sleeve 3 rotates, the sponge pad 7 installed on the end face of the first sleeve 2 will rub against the end face of the pipe fitting 6 installed in the second sleeve 3 that is close to the first sleeve 2, so as to clean the welding surface of the pipe fitting 6 installed in the second sleeve 3.

[0034] Specifically, two supports 8 are fixedly installed on the base 1. One of the supports 8 is located at the end of the first sleeve 2 away from the second sleeve 3, and the other support 8 is located at the end of the second sleeve 3 away from the first sleeve 2. The fixed shaft 9 is fixedly installed on the support 8.

[0035] Furthermore, a driving module for driving the second sleeve 3 to rotate is installed between the second sleeve 3 and the base 1.

[0036] The driving module includes a connecting rod 5 and a first hydraulic rod 4.

[0037] Among them: the connecting rod 5 is fixedly installed on the outer side surface of the second sleeve 3, and the axis of the connecting rod 5 is parallel to the axis of the second sleeve 3.

[0038] The axis of the first hydraulic rod 4 is perpendicular to the axis of the second sleeve 3. The first hydraulic rod 4 is hinged on the base 1, and the output end of the first hydraulic rod 4 is rotatably connected to the connecting rod 5.

[0039] During initial installation, the first sleeve 2 is not coaxial with the second sleeve 3. The connecting rod 5 is located on the side of the second sleeve 3 close to the first hydraulic rod 4. Start the first hydraulic rod 4, and the first hydraulic rod 4 extends, driving the second sleeve 3 to rotate around the fixed shaft 9 through the connecting rod 5. When the first hydraulic rod 4 pushes the second sleeve 3 to rotate until it is coaxial with the first sleeve 2, stop the first hydraulic rod 4 to perform the next welding work.

[0040] A welding torch main body 17 is fixedly installed on the fixed shaft 9. The end faces of the first sleeve 2 and the second sleeve 3 close to each other and the axis of the welding torch main body 17 are located in the same vertical plane.

[0041] When the second sleeve 3 rotates to be coaxial with the first sleeve 2, the pipe fittings 6 in the second sleeve 3 and the pipe fittings 6 in the first sleeve 2 are in a coaxial state. At the same time, the end faces of the pipe fittings 6 in the second sleeve 3 and the pipe fittings 6 in the first sleeve 2 are in contact. The welding torch main body 17 is located outside the end faces where the two pipe fittings 6 are in contact with each other, and can perform welding work on the pipe fittings 6.

[0042] Furthermore, a third hydraulic rod 16 is fixedly installed on the fixed shaft 9 where the first sleeve 2 and the second sleeve 3 are close to each other. The axis of the third hydraulic rod 16 is perpendicular to the axis direction of the first sleeve 2. The welding torch main body 17 is fixedly installed on the telescopic end of the third hydraulic rod 16.

[0043] The third hydraulic rod 16 can be extended and retracted to adjust the position of the welding torch body 17, so that the welding torch body 17 can approach or move away from the workpiece to be welded.

[0044] Clamping and conveying modules are installed in both the first sleeve 2 and the second sleeve 3. The two pipe fittings 6 to be welded are respectively installed in the first sleeve 2 and the second sleeve 3 through the clamping and conveying modules.

[0045] The clamping and conveying module can clamp the pipe fitting 6 to be welded and drive the pipe fitting 6 to move and rotate in the corresponding first sleeve 2 and second sleeve 3.

[0046] The clamping and conveying module can clamp the pipe fitting 6 to be welded and drive the pipe fitting 6 to move in the corresponding first sleeve 2 and second sleeve 3, in order to adjust the position of the pipe fitting 6 in the first sleeve 2 and the second sleeve 3, so that the welding surfaces of the pipe fittings 6 located in the first sleeve 2 and the second sleeve 3 can abut.

[0047] Please refer to the appendix Figure 7 , when the second sleeve 3 is not coaxial with the first sleeve 2 in the initial state, the cross-section of the second sleeve 3 coincides with the cross-section of the pipe fitting 6 installed in the first sleeve 2, and the cross-section of the first sleeve 2 coincides with the cross-section of the pipe fitting 6 installed in the second sleeve 3. Then when installing the pipe fitting 6, the end face of the first sleeve 2 close to the second sleeve 3 can axially position the pipe fitting 6 installed in the second sleeve 3. Similarly, the end face of the second sleeve 3 close to the first sleeve 2 can axially position the pipe fitting 6 installed in the first sleeve 2.

[0048] The clamping and conveying module can clamp the pipe fitting 6 to be welded and drive the pipe fitting 6 to rotate in the corresponding first sleeve 2 and second sleeve 3, in order to enable the welding torch body 17 to perform circumferential welding on the pipe fitting 6 during the welding process.

[0049] Specifically, the clamping and conveying module includes: a hydraulic unit, a first motor 12 and a roller 15.

[0050] Among them, multiple groups of hydraulic units are provided. The multiple groups of hydraulic units are evenly distributed along the axial directions of the first sleeve 2 and the second sleeve 3. Each group of hydraulic units includes a plurality of second hydraulic rods 11. The plurality of second hydraulic rods 11 are respectively fixedly installed on the inner side surfaces of the first sleeve 2 and the second sleeve 3 in a circumferentially evenly distributed manner. The axis of the output shaft of the second hydraulic rod 11 is arranged along the radial direction of the corresponding first sleeve 2 and second sleeve 3.

[0051] A plurality of first motors 12 are provided and are in one-to-one correspondence with the second hydraulic rods 11. The first motors 12 are fixedly installed on the output shafts of the second hydraulic rods 11.

[0052] A plurality of the roller wheels 15 are provided and are in one-to-one correspondence with the second hydraulic rods 11. A connecting seat 13 is rotatably installed on each roller wheel 15. The connecting seat 13 is fixedly installed on the output shaft of the first motor 12. The roller wheels 15 are controlled by a second motor 14.

[0053] When the first motor 12 rotates, the axial direction of the roller wheel 15 can be adjusted. Thus, the movement state of the pipe fitting 6 in the first sleeve 2 or the second sleeve 3 is adjusted.

[0054] Specifically, when the axial direction of the roller wheel 15 is adjusted to be along the tangent direction of the pipe fitting 6, please refer to the appendix Figure 7 , at this time, the second motor 14 drives the roller wheel 15 to rotate, and the friction between the roller wheel 15 and the pipe fitting 6 can cause the pipe fitting 6 to move along the axial direction of the first sleeve 2 or the second sleeve 3.

[0055] When the axial direction of the roller wheel 15 is adjusted to be along the axial direction of the pipe fitting 6, at this time, the second motor 14 drives the roller wheel 15 to rotate, and the friction between the roller wheel 15 and the pipe fitting 6 can cause the pipe fitting 6 to rotate in the first sleeve 2 or the second sleeve 3.

[0056] An exhaust pipe 10 is fixedly installed in the fixed shaft 9. One end of the exhaust pipe 10 faces the inner cavity at the contact of the first sleeve 2 and the second sleeve 3, and the other end of the exhaust pipe 10 is located outside the fixed shaft 9 and is connected to a suction fan.

[0057] The toxic gas generated by welding can be discharged from the exhaust pipe 10.

[0058] Preferably, in this application, when the axes of the first sleeve 2 and the second sleeve 3 coincide, sensors can be arranged at the relative positions of the first sleeve 2 and the second sleeve 3. The sensors are connected to the first hydraulic rod 4 through a control circuit. The sensors transmit the sensed signals to the first hydraulic rod 4 to control the start and stop of the first hydraulic rod 4.

[0059] Meanwhile, position sensors are installed on the end face of the first sleeve 2 close to the second sleeve 3 and on the end face of the second sleeve 3 close to the first sleeve 2 to sense the position of the pipe fitting 6. A pressure sensor is installed on the second hydraulic rod 11 to sense the clamping force.

[0060] The position sensors are connected to the first motor 12, the second hydraulic rod 11, the second motor 14 and the welding torch body 17 through a control circuit.

[0061] The specific control principle is as follows: Initially, the first sleeve 2 is not coaxial with the second sleeve 3, and the axis of the roller wheel 15 is along the tangent direction of the first sleeve 2 or the second sleeve 3.

[0062] Install two pipe fittings 6 into the first sleeve 2 and the second sleeve 3 respectively. During installation, insert the two pipe fittings 6 into the first sleeve 2 and the second sleeve 3 respectively. Subsequently, start the second hydraulic rod 11, and the second hydraulic rod 11 drives the roller 15 to move towards the pipe fitting 6. The roller 15 contacts the pipe fitting 6 and clamps the pipe fitting 6.

[0063] When the pressure sensor on the second hydraulic rod 11 reaches the set value, it transmits an electrical signal to the second motor 14 and the second hydraulic rod 11. The second hydraulic rod 11 stops extending and the second motor 14 starts, causing the roller 15 to rotate. The rotation of the roller 15 moves the pipe fitting 6 towards the end face on the side close to the welding torch body 17.

[0064] When the position sensors on the first sleeve 2 and the second sleeve 3 sense the pipe fitting 6, they transmit signals to the first hydraulic rod 4 and the second motor 14, causing the second motor 14 to stop and the first hydraulic rod 4 to start extending. The extension of the first hydraulic rod 4 drives the second sleeve 3 to rotate around the fixed shaft 9.

[0065] When the second sleeve 3 rotates to be coaxial with the first sleeve 2, the sensors at the relative positions of the first sleeve 2 and the second sleeve 3 transmit signals to the first hydraulic rod 4 and the first motor 12. The first hydraulic rod 4 stops extending and the first motor 12 starts. When the first motor 12 drives the roller 15 to rotate until the axis of the roller 15 is parallel to the axis of the first sleeve 2, the first motor 12 stops rotating, the second motor 14 starts, and the welding torch body 17 starts simultaneously.

[0066] The above control method is only to make the operation of this application simpler. This application can also be used normally without the above control method. The sensors and each motor as well as the hydraulic rod can be controlled by PLC programming or by a control circuit. Whether it is PLC programming control or control through a control circuit, those skilled in the art can make corresponding programming or control circuits according to the above actions. Therefore, no detailed description of the specific programming or control circuit is given here.

[0067] The specific usage method of the present invention is as follows:

[0068] Initial state: The first sleeve 2 and the second sleeve 3 are not coaxial, and the axis of the roller 15 is along the tangent direction of the first sleeve 2 or the second sleeve 3.

[0069] When welding the pipe fitting 6, first insert the two pipe fittings 6 into the first sleeve 2 from the left side by a certain distance and into the second sleeve 3 from the right side by a certain distance. Subsequently, start multiple groups of second hydraulic rods 11. Make the multiple rollers 15 in the circumferential direction of the first sleeve 2 and the second sleeve 3 abut against the outer wall of the pipe fitting 6, thereby completing the centering and clamping of the pipe fitting 6.

[0070] Please refer to the appendixFigure 2 and the attached Figure 3 , the attached Figure 2 and the attached Figure 3 shows the initial state of the roller 15, that is, the axis of the roller 15 is along the tangent direction of the first sleeve 2 or the second sleeve 3.

[0071] Start the second motor 14 to drive the roller 15 to rotate. At this time, the clamped pipe fitting 6 moves along the axis of the first sleeve 2 or the second sleeve 3 under the rotation of the roller 15. That is to say: the pipe fitting 6 in the first sleeve 2 is conveyed towards the direction close to the second sleeve 3, and the pipe fitting 6 in the second sleeve 3 is conveyed towards the direction close to the first sleeve 2.

[0072] Please refer to the attached Figure 4 and the attached Figure 5 , when the pipe fitting 6 in the first sleeve 2 reaches the end face of the second sleeve 3, it stops moving. At this time, the sponge pad 7 at the joint of the first sleeve 2 and the second sleeve 3 is in a squeezed state. Turn off the second motor 14, and the roller 15 stops rotating. After the second motor 14 is turned off, its motor shaft has a self-locking function, and the roller 15 is in a non-rotatable state, so that the pipe fitting 6 remains in this state without moving.

[0073] Similarly, the pipe fitting 6 in the second sleeve 3 performs the same action to complete the positioning of the two pipe fittings 6 to be welded.

[0074] After the positioning of the two pipe fittings 6 is completed, start the first hydraulic rod 4, and the first hydraulic rod 4 drives the second sleeve 3 to rotate around the fixed shaft 9. During the rotation of the second sleeve 3 around the fixed shaft 9, the welding surfaces of the pipe fittings 6 in the second sleeve 3 will all contact the sponge pad 7, so that the sponge pad 7 can clean the fine impurities such as dust and oil stains on the opposite end faces of the pipe fittings 6 to ensure the firmness and sealing performance of the subsequent welding. Similarly, the pipe fitting 6 in the first sleeve 2 will also be cleaned by the sponge pad 7 of the second sleeve 3, so that the welding end faces of the two pipe fittings 6 are both cleaned.

[0075] Please refer to the attached Figure 4 , the axis of the welding torch body 17, the end face of the first sleeve 2, the end face of the second sleeve 3, and the end faces of the two pipe fittings 6 are all in the same vertical plane. Then after the second sleeve 3 rotates in place, the state of the present application please refer to the attached Figure 8 and the attached Figure 9 . At this time, the first sleeve 2 and the second sleeve 3 are coaxial, the welding parts of the two pipe fittings 6 are in contact, and the docking positions of the two pipe fittings 6 are aligned with the welding interfaces of the welding torch body 17, so as to facilitate subsequent welding.

[0076] After completing the above steps, start the first motor 12 to drive the connecting seat 13 to rotate, so that the roller 15 changes its angle, and the axis of the roller 15 rotates to a state parallel to the axis of the pipe fitting 6. At the same time, adjust the third hydraulic rod 16 to adjust the distance between the welding torch body 17 and the pipe fitting 6 for welding work.

[0077] Subsequently, start the welding work. Start the welding torch body 17 and at the same time start the second motor 14. The second motor 14 drives the roller 15 to rotate, and the pipe fitting 6 will rotate during the rotation of the roller 15. The rotation of the pipe fitting 6 enables the welding torch body 17 to weld the circumferential direction of the pipe fitting 6.

[0078] During the welding process, since the first sleeve 2 and the second sleeve 3 form a closed area, the fumes generated by welding cannot directly contact people and cause harm to people. Any harmful fume gases generated during welding will be extracted through the exhaust pipe 10 for unified collection and discharge.

[0079] After the subsequent welding is completed, start the first motor 12 to drive the connecting seat 13 to rotate, so that the roller 15 changes its angle again, and the axis of the roller 15 faces the tangent direction of the pipe fitting 6 again. Start the second motor 14, and the second motor 14 drives the roller 15 to rotate. The roller 15 sends out the pipe fitting 6, and then the welded pipe fitting 6 can be taken out.

[0080] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
