Description

Technical Field

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

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

At this time, the pipe is clamped between the four groups of clamps, thereby fixing the clamps. When the pipe needs to be disassembled, the first gear is driven to return to the initial position radially, and the four groups of clamps release the fixation of the pipe.

[0005] The above-mentioned prior art has the following problems: First, when installing the pipes to be welded, the welding position of the pipes to be welded is likely to have oil stains or other dirt.

Second, in the above-mentioned prior art, when positioning the pipes, baffles are used for positioning. The baffles have a certain thickness, which will inevitably lead to a large gap between the welding surfaces of the two pipes during welding, which ultimately affects the welding quality.

DETAILED DESCRIPTION

[0017] 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.

[0018] like Figure 1-Figure 9 As shown, the technical solution adopted by the present invention is as follows: a fixed-wing manned aircraft welding equipment. It includes a base 1, on the upper end surface of the base 1, a first sleeve 2 is fixedly installed with an axis arranged in the horizontal direction. A fixed shaft 9 with an 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.

[0019] Sponge pads 7 are installed on the end surfaces of the first sleeve 2 and the second sleeve 3 that are close to each other.

[0020] During the initial installation, the first sleeve 2 and the second sleeve 3 are not coaxial, and the pipe fitting 6 is installed in the first sleeve 2 and the second sleeve 3 respectively. Before welding, the second sleeve 3 should be rotated to a position coaxial with the first sleeve 2. When the second sleeve 3 rotates around the fixed axis 9, the second sleeve 3 simultaneously drives the pipe fitting 6 installed in the second sleeve 3 to rotate together, and 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 close to the second sleeve 3, and 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 close to the first sleeve 2, and clean the welding surface of the pipe fitting 6 installed in the second sleeve 3.

[0021] Specifically, two supports 8 are fixedly mounted on the base 1. The two supports 8 are respectively located at two ends of the first sleeve 2 and the second sleeve 3. The fixed shaft 9 is fixedly mounted on the supports 8.

[0022] Furthermore, a driving module for driving the second sleeve 3 to rotate is installed between the second sleeve 3 and the base 1 .

[0023] The driving module comprises a connecting rod 5 and a first hydraulic rod 4 .

[0024] Wherein: the connecting rod 5 is fixedly mounted on the outer side of the second sleeve 3 , and the axis of the connecting rod 5 is parallel to the axis of the second sleeve 3 .

[0025] 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.

[0026] During initial installation, the first sleeve 2 is not coaxial with the second sleeve 3, and the connecting rod 5 is located on the second sleeve 3 near the first hydraulic rod 4. When the first hydraulic rod 4 is started, the first hydraulic rod 4 extends, and the second sleeve 3 is driven to rotate around the fixed axis 9 through the connecting rod 5. When the first hydraulic rod 4 pushes the second sleeve 3 to rotate to be coaxial with the first sleeve 2, the first hydraulic rod 4 is stopped to proceed to the next step of welding.

[0027] The welding gun body 17 is fixedly mounted on the fixed shaft 9 , and the end surfaces of the first sleeve 2 and the second sleeve 3 that are close to each other and the axis of the welding gun body 17 are located on the same vertical plane.

[0028] When the second sleeve 3 rotates to be coaxial with the first sleeve 2, the pipe fitting 6 in the second sleeve 3 and the pipe fitting 6 in the first sleeve 2 are in a coaxial state, and at the same time, the end faces of the pipe fitting 6 in the second sleeve 3 and the end faces of the pipe fitting 6 in the first sleeve 2 are abutted, and the welding gun body 17 is located outside the end faces of the two pipe fittings 6 abutting each other, so that the pipe fitting 6 can be welded.

[0029] Furthermore, a third hydraulic rod 16 is fixedly mounted on the fixed shaft 9 adjacent to the first sleeve 2 and the second sleeve 3. The axis of the third hydraulic rod 16 is perpendicular to the axis of the first sleeve 2. The welding gun body 17 is fixedly mounted on the telescopic end of the third hydraulic rod 16.

[0030] The third hydraulic rod 16 can be extended or shortened to adjust the position of the welding gun body 17, so that the welding gun body 17 is close to or away from the workpiece to be welded.

[0031] The first sleeve 2 and the second sleeve 3 are both provided with clamping and conveying modules. The two pipes 6 to be welded are respectively installed in the first sleeve 2 and the second sleeve 3 through the clamping and conveying modules.

[0032] The clamping and conveying module can clamp the pipe 6 to be welded and drive the pipe 6 to move and rotate in the corresponding first sleeve 2 and second sleeve 3 .

[0033] The clamping and conveying module can clamp the pipe 6 to be welded and drive the pipe 6 to move in the corresponding first sleeve 2 and second sleeve 3, so as to adjust the position of the pipe 6 in the first sleeve 2 and second sleeve 3 so that the surfaces to be welded of the pipe 6 located in the first sleeve 2 and second sleeve 3 can abut against each other.

[0034] Please refer to the attached Figure 7 , in the initial state, when the second sleeve 3 is not coaxial with the first sleeve 2, the cross section of the second sleeve 3 overlaps with the cross section of the pipe 6 installed in the first sleeve 2, and the cross section of the first sleeve 2 overlaps with the cross section of the pipe 6 installed in the second sleeve 3. Then, when installing the pipe 6, the end surface of the first sleeve 2 close to the second sleeve 3 can axially position the pipe 6 installed in the second sleeve 3. Similarly, the end surface of the second sleeve 3 close to the first sleeve 2 can axially position the pipe 6 installed in the first sleeve 2.

[0035] The clamping and conveying module can clamp the pipe 6 to be welded and drive the pipe 6 to rotate in the corresponding first sleeve 2 and second sleeve 3, so that the welding gun body 17 can perform circumferential welding on the pipe 6 during the welding process.

[0036] Specifically, the clamping and conveying module includes: a hydraulic unit, a first motor 12 and a roller 15 .

[0037] There are multiple groups of hydraulic units. The multiple groups of hydraulic units are evenly arranged along the axial direction of the first sleeve 2 and the second sleeve 3. Each group of hydraulic units includes multiple second hydraulic rods 11. The multiple second hydraulic rods 11 are evenly arranged and fixedly installed on the inner side surfaces of the first sleeve 2 and the second sleeve 3. The output shaft axis of the second hydraulic rod 11 is arranged along the radial direction of the corresponding first sleeve 2 and the second sleeve 3.

[0038] The first motors 12 are provided in plurality and correspond one to one with the second hydraulic rods 11 . The first motors 12 are fixedly mounted on the output shaft of the second hydraulic rod 11 .

[0039] The rollers 15 are provided in plurality and correspond one to one with the second hydraulic rods 11. A connecting seat 13 is rotatably mounted on each roller 15. The connecting seat 13 is fixedly mounted on the output shaft of the first motor 12. The rollers 15 are controlled by the second motor 14.

[0040] The first motor 12 rotates to adjust the axial direction of the roller 15 , thereby adjusting the motion state of the pipe 6 in the first sleeve 2 or the second sleeve 3 .

[0041] Specifically, when the axial direction of the roller 15 is adjusted to the tangential direction of the pipe 6, please refer to the attached Figure 7 At this time, the second motor 14 drives the roller 15 to rotate, and the friction between the roller 15 and the pipe 6 can make the pipe 6 move along the axial direction of the first sleeve 2 or the second sleeve 3.

[0042] When the axial direction of the roller 15 is adjusted to be along the axial direction of the pipe 6 , the second motor 14 drives the roller 15 to rotate, and the friction between the roller 15 and the pipe 6 can make the pipe 6 rotate in the first sleeve 2 or the second sleeve 3 .

[0043] An exhaust pipe 10 is fixedly installed in the fixed shaft 9, one end of the exhaust pipe 10 faces the inner chamber where the first sleeve 2 and the second sleeve 3 meet, and the other end of the exhaust pipe 10 is located outside the fixed shaft 9 and connected to a suction fan.

[0044] Toxic gas from welding can be discharged from the exhaust pipe 10 .

[0045] Preferably, in the present application, when the axes of the first sleeve 2 and the second sleeve 3 coincide, a sensor can be set at the relative positions of the first sleeve 2 and the second sleeve 3, and the sensor is connected to the first hydraulic rod 4 through a control circuit. The sensor transmits the sensed signal to the first hydraulic rod 4 to control the start and stop of the first hydraulic rod 4.

[0046] At the same time, position sensors are installed on the end surface of the first sleeve 2 close to the second sleeve 3 and on the end surface of the second sleeve 3 close to the first sleeve 2, and the position sensors sense the position of the pipe 6. A pressure sensor is installed on the second hydraulic rod 11, and the pressure sensor senses the clamping force.

[0047] The position sensor is connected to the first motor 12 , the second hydraulic rod 11 , the second motor 14 and the welding gun body 17 via a control circuit.

[0048] 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 15 is along the tangent direction of the first sleeve 2 or the second sleeve 3 .

[0049] The two pipes 6 are installed in the first sleeve 2 and the second sleeve 3 respectively. During installation, the two pipes 6 are respectively inserted into the first sleeve 2 and the second sleeve 3. Then the second hydraulic rod 11 is started, and the second hydraulic rod 11 drives the roller 15 to move in the direction close to the pipe 6, and the roller 15 contacts the pipe 6 and clamps the pipe 6.

[0050] The pressure sensor on the second hydraulic rod 11 reaches the set value, and 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, so that the roller 15 rotates. The roller 15 rotates to move the pipe 6 toward the end surface close to the welding gun body 17.

[0051] When the position sensors on the first sleeve 2 and the second sleeve 3 sense the pipe 6, they transmit signals to the first hydraulic rod 4 and the second motor 14, so that the second motor 14 stops and the first hydraulic rod 4 starts to extend. The extension of the first hydraulic rod 4 drives the second sleeve 3 to rotate around the fixed axis 9.

[0052] When the second sleeve 3 rotates to be coaxial with the first sleeve 2, the sensor of the relative position of the first sleeve 2 and the second sleeve 3 transmits a signal to the first hydraulic rod 4 and the first motor 12, the first hydraulic rod 4 stops extending, and the first motor 12 starts to start. 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 to start, and the welding gun body 17 starts at the same time.

[0053] The above control method is only to make the operation of this application simpler. This application can be used normally without the above control method. The sensor and each motor and hydraulic rod can be controlled by PLC programming or by control circuit. Whether it is PLC programming control or control by control circuit, those skilled in the art can make corresponding programming or control circuit according to the above actions. Therefore, no detailed description of the specific programming or control circuit is given here.

[0054] The specific method of use of the present invention is as follows: 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.

[0055] When welding the pipe fittings 6, firstly, the two pipe fittings 6 are respectively inserted a certain distance from the left side of the first sleeve 2 and a certain distance from the right side of the second sleeve 3. Then, by starting multiple sets of second hydraulic rods 11, multiple rollers 15 in the circumferential direction of the first sleeve 2 and the second sleeve 3 are pressed against the outer wall of the pipe fittings 6, thereby completing the centering clamping of the pipe fittings 6.

[0056] Please refer to the attached Figure 2 and attached Figure 3 , attached Figure 2 and attached Figure 3 The initial state of the roller 15 is shown, that is, the axis of the roller 15 is along the tangent direction of the first sleeve 2 or the second sleeve 3.

[0057] The second motor 14 is started to drive the roller 15 to rotate, and the clamped pipe 6 is moved along the axis of the first sleeve 2 or the second sleeve 3 under the rotation of the roller 15. In other words, the pipe 6 in the first sleeve 2 is transported toward the second sleeve 3, and the pipe 6 in the second sleeve 3 is transported toward the first sleeve 2.

[0058] Please refer to the attached Figure 4 and attached Figure 5 , the pipe 6 in the first sleeve 2 stops moving when it reaches the end face of the second sleeve 3, and the sponge pad 7 at the joint between the first sleeve 2 and the second sleeve 3 is in a squeezed state. The second motor 14 is turned off, 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, thereby keeping the pipe 6 in this state.

[0059] 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.

[0060] After the two pipes 6 are positioned, the first hydraulic rod 4 is started, and the first hydraulic rod 4 drives the second sleeve 3 to rotate around the fixed axis 9. During the rotation of the second sleeve 3 around the fixed axis 9, the welding surface of the pipe 6 in the second sleeve 3 will contact the sponge pad 7, so that the sponge pad 7 can clean the dust, oil and other fine impurities on the opposite end surface of the pipe 6 to ensure the firmness and sealing of the subsequent welding. Similarly, the pipe 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 surfaces of the two pipes 6 are cleaned.

[0061] Please refer to the attached Figure 4 The axis of the welding gun 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 pipes 6 are all on the same vertical plane. After the second sleeve 3 is rotated into place, the state of this application is shown in the attached Figure 8 and attached Fig. 9 At this time, the first sleeve 2 and the second sleeve 3 are coaxial, the welding parts of the two pipes 6 are fitted together, and the butt joints of the two pipes 6 are aligned with the welding ports of the welding gun body 17 to facilitate subsequent welding.

[0062] After completing the above steps, the first motor 12 is started to drive the connecting seat 13 to rotate so that the roller 15 changes its angle, so that the axis of the roller 15 rotates to a state parallel to the axis of the pipe 6. At the same time, the third hydraulic rod 16 is adjusted to adjust the distance between the welding gun body 17 and the pipe 6 to perform welding.

[0063] Then, the welding work starts. The welding gun body 17 is started and the second motor 14 is started at the same time, and the second motor 14 drives the roller 15 to rotate. The roller 15 rotates during the rotation process. The pipe 6 rotates so that the welding gun body 17 welds the pipe 6 in the circumferential direction.

[0064] During the welding process, since the first sleeve 2 and the second sleeve 3 form a closed area, the fume generated by welding cannot directly contact people and cause harm to people. Harmful fume gases generated during welding will be extracted through the exhaust pipe 10 for unified collection and discharge.

[0065] After subsequent welding is completed, the first motor 12 is started to drive the connecting seat 13 to rotate so that the roller 15 changes its angle, so that the axis of the roller 15 is again oriented toward the tangent direction of the pipe 6. The second motor 14 is started, and the second motor 14 drives the roller 15 to rotate, and the roller 15 sends the pipe 6 out, so that the welded pipe 6 can be taken out.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
