Description

Technical Field

[0001] The invention relates to the technical field of aircraft wall panel processing, in particular to large aircraft wall panel composite material forming equipment and method. Background Art

[0002] Aircraft wall panels are usually a thin-walled structure composed of a skeleton layer of an internal reinforcement structure. At present, in the process of docking thin-walled aircraft wall panels, the reinforcement at the docking point is generally only set on one of the wall panels, so there is no reinforcement inside the other wall panel, and the skin layer is not effectively fixed and constrained during the docking process, resulting in the skin at the docking point being easily deformed, affecting the appearance of the docking point. In addition, the existing wall panel docking processing method is usually to achieve indirect positioning through positioning holes set on the reinforcement, and guide through guide plates to complete the docking.

[0003] However, in this assembly method, the docking edge of the skin layer lacks protection, which can easily cause the panel structure without internal reinforcement and its skin layer to deform. In addition, the skin edge is usually far away from the positioning hole, which can easily cause docking misalignment. Moreover, due to the weak structure of the skin edge, it is easy to hinder the docking work, resulting in low docking efficiency. In summary, the existing aircraft panel docking structure has the disadvantages of poor aircraft surface quality, easy dislocation of the panel, and low assembly efficiency. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the present invention provides large aircraft wall panel composite material forming equipment and method to solve the problems raised in the above background technology.

[0006] Second technical solution

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: large aircraft wall panel composite forming equipment and method, large aircraft wall panel composite forming equipment, including a base plate, a fixed bracket is fixedly installed on the top of the base plate, a workbench is fixedly installed on the top of the fixed bracket, a fixed seat one is fixedly installed on the top of the workbench, a skin bag is fixedly installed on the top of the fixed seat, a bag opening is provided on one side of the skin bag, a skin layer is provided on the upper layer inside the skin bag, a release layer is provided on the bottom of the skin layer, a gantry is fixedly installed on the top of the fixed seat one, a telescopic cylinder is fixedly installed on the top of the gantry, a pressure rod is fixedly installed on the bottom of the telescopic cylinder, a pressure plate is fixedly installed on the bottom of the pressure rod, a conveying platform is fixedly installed on the front end of the fixed seat one, a supporting leg is fixedly installed on the bottom of the conveying platform, an inclined plate is fixedly installed on the front end of the conveying platform, and the conveying platform A processing table is fixedly installed in the front, a fan is fixedly installed on the side of the processing table, an air outlet slot is opened on the side of the processing table, an air suction pump is fixedly installed on the right side of the fixed seat one, one end of the air suction pipe is fixedly connected to the top of the air suction pump, an electric slide rail is fixedly installed on the top right side of the workbench, an electric slider is fixedly installed on the electric slide rail, a base is fixedly installed on the top of the electric slider, a motor one is fixedly installed on the side of the base, a small gear is fixedly installed on the output shaft of the motor one, a large gear is fixedly installed on the base through a rotating shaft, a fixed seat two is fixedly installed on the base through a rotating shaft, an electric push rod is fixedly installed in the fixed seat two, a fixed plate is fixedly installed on the output end of the electric push rod, a motor two is fixedly installed in the fixed plate, an electric telescopic rod is fixedly installed on the output shaft of the motor two, and a cutting plate is fixedly installed on the bottom of the electric telescopic rod.

[0008] Preferably, an exhaust groove is provided on the side of the skin bag, and the exhaust groove protrudes from the surface of the skin bag and is cylindrical.

[0009] Through the above technical scheme, compared with other shapes, the cylindrical exhaust groove has a higher utilization efficiency of the internal space under the same cross-sectional area. When the skin bag is evacuated by a vacuum device, the air flows more smoothly in the cylindrical exhaust groove. This smooth air flow helps to increase the exhaust speed, thereby extracting the air in the skin bag faster. The cylindrical structure is not easily blocked by debris that may exist inside the skin bag. The cylindrical structure is relatively smooth, and debris is not easy to accumulate, which can ensure that the exhaust groove maintains good exhaust performance for a long time. Due to the symmetry of the cylindrical exhaust groove, during the exhaust process, it can make the air in various parts of the skin bag be evenly exhausted. The cylindrical exhaust groove can ensure that the air in the skin bag can be exhausted more evenly through a reasonable layout, so that the skin bag can better reach the expected deflated state.

[0010] Preferably, six universal wheels are fixedly mounted on the bottom of the base plate. The six universal wheels are evenly distributed on the bottom of the base plate and can rotate in any direction.

[0011] Through the above technical solution, it is possible to achieve movement in any direction. Since the universal wheel can rotate in any direction, the operator can quickly change the direction of the equipment. Compared with equipment that can only move forward and backward, it does not need to perform cumbersome operations such as reversing and adjusting the body to turn, which greatly improves work efficiency. For users, there is no need to accurately control the direction of each wheel. No matter whether it is a novice or a skilled worker, it can easily push an object with such a universal wheel. In many cases, one person can easily operate equipment with universal wheels.

[0012] Preferably, four fans are installed, and the four fans are respectively located on the air outlet slots on the side of the processing table.

[0013] Through the above technical scheme, four fans working at the same time can significantly improve the speed of air drying. The four fans blow air from different positions on the side of the processing table, and can simultaneously air dry multiple parts of the workpiece, greatly shortening the overall air drying time. Since the four fans are located on the air outlet slots on the side of the processing table, they can air dry the items on the processing table from different side directions, which can ensure that all sides of the items can be blown by the wind to achieve an all-round air drying effect. The layout of the four fans helps to achieve a uniform air drying effect. The four fans blow air from different angles, which can make the surface of the items on the processing table subject to a more uniform wind force, making the degree of air drying more consistent.

[0014] Preferably, a connecting port is fixedly installed on the other end of the air extraction pipe, and the connecting port is circular and connected to the air extraction pipe on the air pump.

[0015] Through the above technical solution, when the circular connecting port is connected to the exhaust pipe, it can ensure that the seal is subjected to uniform pressure, because the distance from any point on the circumference of the circle to the center of the circle is equal. When passing through the connecting device, the seal is evenly compressed in the circumferential direction. When using a clamp to connect the circular connecting port and the exhaust pipe, the pressure of the clamp on the circular connecting port is evenly distributed on the circumference, so that the sealing effect is better and the possibility of gas leakage is reduced. The circular pipe has relatively small resistance to airflow. When the airflow flows in the circular connecting port and the exhaust pipe, the streamline of the airflow is smoother than that of other shapes.

[0016] Preferably, the upper portion of the skin bag is an upper wall panel, and the lower portion is a lower wall panel.

[0017] Through the above technical solution, when the circular connector is connected to the suction pipe of the suction pump, it is easier to achieve sealing due to the geometric characteristics of its shape. The circumference of the circle is continuous and uniform. Compared with other shapes, when using sealing means such as sealing gaskets or sealants, the circular connector can be evenly stressed on the entire circumference. When using a rubber sealing ring for connection, the circular connector can compress the sealing ring evenly, reduce the possibility of gas leakage, and ensure the suction efficiency of the suction pump. The circular connector has good stability in mechanical connection. It can evenly withstand the tension, pressure, torque and other forces from the suction pipe of the suction pump in all directions. During the operation of the equipment, the suction pump may generate vibration when working. The circular connector can better adapt to this vibration and reduce the risk of loose connection.

[0018] Preferably, a cutting knife is fixedly mounted on the bottom of the cutting plate, the bottom end of the cutting knife is inclined, and the cutting knife can rotate according to motor 2.

[0019] Through the above technical scheme, the stable rotation of Motor 2 can make the cutting action of the cutting tool smoother. When the cutting tool cuts the material steadily, the surface of the cut material will be smoother. Due to the rotation characteristics of Motor 2, the cutting tool can work with appropriate cutting force, and the rotation speed and torque of Motor 2 can be adjusted according to the characteristics of the material.

[0020] Preferably, a fixing groove is provided on the top surface of the fixing seat, and the fixing groove is an arc-shaped structure.

[0021] Through the above technical solution, the arc-shaped fixing groove can provide uniform supporting force along the circumferential direction of the shaft. Compared with square or other shaped fixing grooves, the arc-shaped groove can minimize the gap between the component and the fixing groove, thereby making the fixation more stable. For circular or arc-shaped objects, when subjected to external force, the arc-shaped fixing groove can evenly distribute the stress on the contact surface between the object and the fixing groove. The arc-shaped fixing groove can ensure that the crankshaft is supported uniformly during the operation of the engine, reduce local stress concentration, and thus extend the service life of the crankshaft and the fixing seat.

[0022] Preferably, four supporting legs are fixedly installed on the bottom of the conveying platform, the four supporting legs are equidistantly distributed on the bottom of the conveying platform, and the four supporting legs are square structures.

[0023] Through the above technical solution, the equidistantly distributed square supporting legs can evenly distribute the weight borne by the conveyor platform on the four supporting points. When heavier goods are placed on the conveyor platform, the pressure borne by each supporting leg is basically the same. For the conveyor platform, this uniform force helps to prevent structural deformation or damage caused by local excessive pressure. The equidistantly distributed square supporting legs are easy to install. When installing the conveyor platform, the positions of the four square supporting legs can be easily arranged symmetrically according to the geometric center of the bottom of the conveyor platform. This symmetrical arrangement meets the requirements of most installation sites, and during the installation process, the installers can use the right angles of the square legs to quickly determine the accuracy of their positions. The right angles of the square supporting legs can be easily aligned with the marking lines to improve installation efficiency.

[0024] The present invention also provides a method for processing a large aircraft wall panel composite material, and the processing steps are as follows:

[0025] S1: The fixed bracket installed on the top of the bottom plate provides a stable support for the workbench, and then the wall panel to be processed is placed into the skin bag in the fixing seat 1 through the fixing seat 1 on the workbench;

[0026] S2: tear off the release layer, and use the telescopic cylinder in the gantry on the fixed seat to drive the pressure rod to press down, and the downward pressure of the pressure rod drives the pressure plate to press down, so as to compress the skin bag and seal the bag opening, and then connect the vacuum groove on the surface of the skin bag with the connection port at the front end of the vacuum pipe on the suction pump to evacuate the skin bag. When the vacuum is completed, the skin layer on the bottom surface of the upper wall panel inside the skin bag is fitted to the wall panel to be processed, and adhesive is provided between the skin layer and the release layer, and the skin layer is bonded and connected to the wall panel by the adhesive;

[0027] S3: The compacted wall panels are dropped from the conveyor belt on the conveyor table through the inclined plate into the processing table, and then the fan is started. The fan dries the adhesive between the wall panels and the skin layer on the processing table through the air outlet slot on the side of the processing table;

[0028] S4: The electric slider slides on the electric slide rail to drive the base on the electric slider to move, and then the motor 1 is started. The output shaft of the motor 1 drives the small gear to rotate, and the rotation of the small gear drives the large gear to rotate, so that the entire robotic arm can rotate left and right, and then the electric push rod in the fixed seat 2 drives the fixed plate to move;

[0029] S5: Motor 2 in the fixed plate drives the electric telescopic rod, which drives the cutting plate to press down, and the cutting plate drives the cutting knife at the bottom of the cutting plate to press down. Then, motor 2 rotates to make the cutting knife rotate, so that the cutting knife changes position to cut the wall panel to be processed, and finally a finished product is obtained.

[0030] Compared with the prior art, the present invention provides large aircraft wall panel composite molding equipment and method, which have the following beneficial effects: the large aircraft wall panel composite molding equipment and method can ensure the internal structural integrity of the wall panel composite. Through precise process parameter control, the fibers of the composite material are arranged neatly, the matrix and the reinforcing fibers are well bonded, internal defects are reduced, the overall strength and durability of the wall panel are improved, and precise molding of complex shapes can be achieved. The wall panels of large aircraft have complex shapes, and the molding equipment can adapt to various special shape requirements such as curved surfaces and thin walls, ensuring that the shape accuracy of the wall panels meets the design standards, which is beneficial to the aerodynamic performance of the aircraft, and has the characteristics of automation and integration, reducing manual operation links, thereby shortening the molding cycle, and mass production can be carried out. Once the molding equipment is debugged, it can stably mold the composite wall panels according to the set process parameters, which is suitable for large-scale production needs and meets the output requirements of aircraft manufacturing.

[0040] 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.

[0041] like Figure 1-8As shown, large aircraft wall panel composite forming equipment includes a base plate 1, a fixed bracket 2 is fixedly installed on the top of the base plate 1, a workbench 3 is fixedly installed on the top of the fixed bracket 2, a fixed seat 4 is fixedly installed on the top of the workbench 3, a skin bag 5 is fixedly installed on the top of the fixed seat, a bag opening 6 is arranged on one side of the skin bag 5, a skin layer 7 is arranged on the upper layer inside the skin bag 5, a release layer 8 is arranged on the bottom of the skin layer 7, a gantry 9 is fixedly installed on the top of the fixed seat 4, a telescopic cylinder 10 is fixedly installed on the top of the gantry 9, a pressure rod 11 is fixedly installed on the bottom of the telescopic cylinder 10, a pressure plate 12 is fixedly installed on the bottom of the pressure rod 11, a conveying platform 14 is fixedly installed on the front end of the fixed seat 4, a supporting leg 13 is fixedly installed on the bottom of the conveying platform 14, an inclined plate 15 is fixedly installed on the front end of the conveying platform 14, a processing platform 16 is fixedly installed in front of the conveying platform 14, and a wind turbine is fixedly installed on the side of the processing platform 16. Machine 17, an air outlet slot 18 is provided on the side of the processing table 16, an air suction pump 19 is fixedly installed on the right side of the fixed seat 4, and one end of the air suction pipe 20 is fixedly connected to the top of the air suction pump 19, an electric slide rail 21 is fixedly installed on the right side of the top of the workbench 3, an electric slider 23 is fixedly installed on the electric slide rail 21, a base 24 is fixedly installed on the top of the electric slider 23, a motor 25 is fixedly installed on the side of the base 24, a small gear 26 is fixedly installed on the output shaft of the motor 25, a large gear 27 is fixedly installed on the base 24 through a rotating shaft, a fixed seat 28 is fixedly installed on the base 24 through a rotating shaft, an electric push rod 29 is fixedly installed in the fixed seat 28, a fixed plate 30 is fixedly installed on the output end of the electric push rod 29, a motor 2 31 is fixedly installed in the fixed plate 30, an electric telescopic rod 32 is fixedly installed on the output shaft of the motor 2 31, and a cutting plate 33 is fixedly installed at the bottom of the electric telescopic rod 32.

[0042] Furthermore, an air extraction groove 503 is provided on the side of the skin bag 5 , and the air extraction groove 503 protrudes from the surface of the skin bag 5 and is cylindrical.

[0043] Specifically, the exhaust groove 503 protrudes from the surface of the skin bag 5, which makes it easier to connect with the exhaust pipe 20. The exhaust groove 503 is cylindrical and has the same shape as the exhaust pipe 20, so there will be no air leakage. Compared with other shapes, the cylindrical exhaust groove 503 has a relatively larger volume of the internal space under the same cross-sectional area. The exhaust groove 503 protrudes from the surface of the skin bag 5. This protruding design can reduce the resistance of the air during the exhaust process, because the air flow space around the protruding part is relatively wider, and the air can be more easily attracted into the exhaust groove 503 by the exhaust equipment without being excessively obstructed by the surface of the skin bag 5.

[0044] Furthermore, six universal wheels 35 are fixedly installed at the bottom of the base plate 1. The six universal wheels 35 are evenly distributed at the bottom of the base plate 1 and can rotate in any direction.

[0045] Specifically, the six universal wheels 35 provide more stable support. During the movement, the six universal wheels 35 are easier to maintain balance. Multiple wheels share the weight, making the load-bearing capacity of the base plate 1 stronger. Since the universal wheels 35 can rotate in any direction, the device equipped with the base plate 1 can achieve all-round movement. The device can easily move in any direction by rotating the direction of the universal wheels 35, without having to adjust the overall orientation of the device before changing the moving direction like traditional directional wheels.

[0046] Furthermore, four fans 17 are installed, and the four fans 17 are respectively located on the air outlet slots 18 on the side of the processing table 16.

[0047] Specifically, multiple fans 17 working together can achieve rapid drying of the workpiece to be processed. The layout of the four fans 17 helps to make the temperature distribution in the entire processing table 16 more uniform. The four fans 17 are respectively located on the air outlet slots 18 on the sides of the processing table 16, which can achieve more comprehensive coverage of the air around the processing table 16. The collaborative work of multiple fans 17 can improve the ventilation efficiency. When the four fans 17 are running at the same time, the total ventilation volume will be much larger than that of a single fan 17. The layout of the four fans 17 helps to form a stable and balanced airflow. Since they are respectively located on the sides of the processing table 16, they can cooperate with each other during operation to make the airflow evenly distributed around the processing table 16.

[0048] Furthermore, a connecting port 2001 is fixedly installed on the other end of the air extraction pipe 20 . The connecting port 2001 is circular and connected to the air extraction pipe 20 on the air suction pump 19 .

[0049] Specifically, when the connection port 2001 is circular, it is easier to achieve a good seal when it is connected to the exhaust pipe 20 on the suction pump 19. The circular structure can be in uniform contact with the exhaust pipe 20 during connection, reducing the possibility of gas leakage. The circular connection port 2001 can achieve a relatively uniform contact with the exhaust pipe 20 because the circle is a highly symmetrical geometric shape. When connected, the distance from each point on the circumference to the center of the circle is equal.

[0050] Furthermore, the upper portion of the skin bag 5 is an upper wall panel 501 , and the lower portion is a lower wall panel 502 .

[0051] Specifically, during the manufacturing process, the skin bag 5 is divided into an upper and lower wall panel structure, which is easier to produce and process. This method reduces the complexity of manufacturing. The structural design of the upper wall panel 501 and the lower wall panel 502 is equivalent to layered reinforcement of the overall structure of the skin bag 5. This layered structure can increase the stability of the skin bag 5 when it is subjected to external pressure.

[0052] Furthermore, a cutting knife 34 is fixedly mounted on the bottom of the cutting plate 33 , and the bottom end of the cutting knife 34 is inclined, and the cutting knife 34 can rotate according to the motor 2 31 .

[0053] Specifically, the design of the bevel allows the cutting blade 34 to gradually enter the material to be cut. The bevel can reduce the contact area between the cutting blade 34 and the material when it initially contacts the material. The cutting blade 34 can rotate according to the motor 2 31, and the cutting angle can be easily adjusted, thereby achieving precise engraving of different shapes and textures, making the wear more uniform and extending the life of the tool.

[0054] Furthermore, stoppers 22 are fixedly mounted on both ends of the electric slide rail 21, and the stoppers 22 are square structures.

[0055] Specifically, the square-structured block 22 has a larger bottom contact area. When it is fixed at both ends of the electric slide rail 21, it can provide more stable support. During the operation of the electric slide rail 21, various forces will be generated. The square block 22 is easier to achieve a stable connection with the electric slide rail 21 and the surrounding installation structure during installation. Due to its regular shape, it can be better positioned and fixed when it is installed by bolting, welding or interlocking with other components.

[0056] Furthermore, a fixing groove 401 is provided on the top surface of the fixing seat 4, and the fixing groove 401 is an arc-shaped structure.

[0057] Specifically, the arc-shaped fixing groove 401 can fit well with the outer contours of these parts. When the arc-shaped structure contacts the circular part, the stress distribution on the contact surface is more uniform. This is because the contact surface between the arc and the circular part is a continuous curve contact, rather than an angular contact like a square groove. The arc-shaped fixing groove 401 can better fit the parts that match it. If the part to be fixed is a round object or an object with an arc-shaped surface, the arc-shaped fixing groove 401 can provide a larger contact area. This fit can increase the stability of the fixation and reduce the shaking of the part in the fixing groove 401.

[0058] A method for processing a large aircraft wall panel composite material, the processing steps are as follows:

[0059] S1: The fixing bracket 2 fixedly installed on the top of the bottom plate 1 provides a stable support for the workbench 3, and then the wall panel to be processed is placed into the skin bag 5 in the fixing seat 4 on the workbench 3;

[0060] S2: tear off the release layer 8, and drive the pressure rod 11 to press down through the telescopic cylinder 10 in the gantry 9 on the fixed seat 4, and the downward pressure of the pressure rod 11 drives the pressure plate 12 to press down, so as to compress the skin bag 5 and seal the bag opening 6, and then connect the vacuum groove 503 on the surface of the skin bag 5 with the connection port 2001 at the front end of the vacuum pipe 20 on the suction pump 19 to evacuate the skin bag 5. When the vacuum is completed, the skin layer 7 on the bottom surface of the upper wall panel 501 inside the skin bag 5 is fitted to the wall panel to be processed, and adhesive is provided between the skin layer 7 and the release layer 8, and the skin layer 7 is bonded to the wall panel through the adhesive;

[0061] S3: The compacted wall panels are dropped from the conveyor belt 1401 on the conveyor platform 14 through the inclined plate 15 into the processing platform 16, and then the fan 17 is started. The fan 17 dries the adhesive between the wall panels and the skin layer 7 in the processing platform 16 through the air outlet slots 18 on the side of the processing platform 16;

[0062] S4: The electric slider 23 slides on the electric slide rail 21 to drive the base 24 on the electric slider 23 to move, and then the motor 1 25 is started. The output shaft of the motor 1 25 drives the small gear 26 to rotate. The rotation of the small gear 26 drives the large gear 27 to rotate, so that the entire mechanical arm can rotate left and right, and then the electric push rod 29 in the fixed seat 28 drives the fixed plate 30 to move;

[0063] S5: Through the motor 2 31 in the fixed plate 30, the motor 2 31 drives the electric telescopic rod 32, and the electric telescopic rod 32 drives the cutting plate 33 to press down. The cutting plate 33 is pressed down and drives the cutting knife 34 at the bottom of the cutting plate 33 to press down. Then, the motor 2 31 rotates to make the cutting knife 34 rotate accordingly, so that the cutting knife 34 changes its position to cut the wall panel to be processed, and finally obtains the finished product.

[0064] Working principle: First, the fixed bracket 2 fixedly installed on the top of the bottom plate 1 provides a stable support for the workbench 3, and then the wall panel to be processed is placed in the skin bag 5 in the fixed seat 4 through the fixed seat 4 on the workbench 3, and the release layer 8 is torn off.

The suction groove 503 on the surface of the skin bag 5 is connected to the connection port 2001 at the front end of the suction pipe 20 on the suction pump 19, and the skin bag 5 is evacuated. When the suction is completed, the skin layer 7 on the bottom surface of the upper wall panel 501 inside the skin bag 5 is fitted to the wall panel to be processed. Glue is provided between the skin layer 7 and the release layer 8, and the skin layer 7 is glued and connected to the wall panel through the glue. Then, the compacted wall panel falls from the conveyor belt 1401 on the conveyor platform 14 through the inclined plate 15 The fan 17 is started to dry the glue between the wall panel and the skin layer 7 in the processing table 16 through the air outlet slot 18 on the side of the processing table 16, and then the electric slider 23 slides on the electric slide rail 21 to drive the base 24 on the electric slider 23 to move, and then the motor 1 25 is started, and the output shaft of the motor 1 25 drives the small gear 26 to rotate, and the rotation of the small gear 26 drives the large gear 27 to rotate, so that the whole robot arm can rotate left and right, and then the electric push rod 29 in the fixed seat 28 drives the fixed plate 30 to move, and then through the motor 2 31 in the fixed plate 30, the motor 2 31 drives the electric telescopic rod 32, and the electric telescopic rod 32 drives the cutting plate 33 to press down, and the cutting plate 33 presses down to drive the cutting knife 34 at the bottom of the cutting plate 33 to press down, and then the motor 2 31 rotates to make the cutting knife 34 rotate accordingly, so that the cutting knife 34 changes its position to cut the wall panel to be processed, and finally a finished product is obtained.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
