Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing marine transition joints, and particularly relates to a device and method for in-situ manufacturing of marine transition joints. Background Art

[0002] Friction stir additive manufacturing is a new type of solid-phase additive manufacturing technology. During the additive manufacturing process, the material does not melt, so fundamentally it solves the defects such as porosity and shrinkage cavities, and thermal cracks generated during the melting and solidification process. Using friction stir additive manufacturing to process composite structures can effectively improve the strength of structural parts.

[0003] The shipbuilding industry is one of the major industries in our country. A steel hull can effectively improve the rigidity of the ship, and an aluminum building can effectively reduce the overall weight of the ship and increase its load-carrying capacity. However, the connection between aluminum and steel is relatively difficult, and an aluminum-steel transition joint structure is often used for connection, that is, purchasing an aluminum-steel composite plate, welding the steel surface of the hull to the aluminum-steel composite plate, and connecting the aluminum surface of the building to the aluminum-steel composite plate. At this time, on the one hand, the number of welds is increased, and on the other hand, the welding temperature of the steel plate reaches 1300 degrees Celsius, which is much higher than the melting point of aluminum alloy, so it poses a challenge to the stability of the transition joint. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, an object of the present invention is to provide a device for in-situ manufacturing of marine transition joints, which can realize in-situ additive manufacturing of an aluminum layer on the steel surface of the hull, reduce the number of welds, and improve the strength and processing efficiency of marine transition joints.

[0005] The device for in-situ manufacturing of marine transition joints according to an embodiment of the present invention includes a grinding assembly, a cleaning assembly, and a friction stir additive manufacturing spindle that are sequentially arranged adjacent to each other and can move synchronously; the grinding assembly is used to grind the surface of the hull; the cleaning assembly is used to clean the ground surface of the hull in a timely manner; the friction stir additive manufacturing spindle is used to in-situ additive manufacture an aluminum layer on the ground and cleaned surface of the hull.

[0006] When the in-situ manufacturing equipment for marine transition joints according to the embodiments of the present invention is in use, after adjusting the positions of the grinding assembly, the cleaning assembly, and the friction stir additive manufacturing spindle relative to the steel surface of the hull (such as by lateral movement and vertical movement), the grinding assembly, the cleaning assembly, and the friction stir additive manufacturing spindle are moved synchronously (such as longitudinally). Correspondingly, the grinding assembly 1 grinds the surface of the hull, the cleaning assembly cleans the ground surface of the hull in a timely manner, and the friction stir additive manufacturing spindle 3 performs in-situ additive manufacturing of an aluminum layer on the ground and cleaned surface of the hull. Among them, during the movement along a path, in the initial movement stage, the grinding assembly and the cleaning assembly first grind and clean the initial position of the hull, and the friction stir additive manufacturing spindle 3 does not perform additive manufacturing until the friction stir additive manufacturing spindle moves to the ground and cleaned surface of the initial position, and then starts to perform additive manufacturing of the aluminum layer; in the subsequent continuous synchronous movement stage, the grinding assembly grinds while moving, the cleaning assembly cleans while moving, and the friction stir additive manufacturing spindle performs in-situ additive manufacturing of the aluminum layer while moving. In the last movement stage, after the grinding assembly and the cleaning assembly complete the grinding and cleaning of the termination position of the hull, the grinding assembly stops the grinding action and the cleaning assembly stops the cleaning action, while the friction stir additive manufacturing spindle still continues to perform in-situ additive manufacturing of the aluminum layer until the aluminum layer manufacturing at the ground and cleaned surface of the termination position is completed. Thus, the aluminum layer processing of one path is completed; when the aluminum layer processing of one path is completed, the aluminum layer of an adjacent path can be completed until the aluminum layer is processed on the steel surface within the required range of the hull.

[0007] By synchronously moving the grinding assembly, the cleaning assembly, and the friction stir additive manufacturing spindle while grinding, cleaning, and performing in-situ additive manufacturing of the aluminum layer on the steel surface of the hull, the in-situ additive manufacturing of the aluminum layer on the steel surface of the hull is realized on the one hand, avoiding the low strength of the marine transition joint caused by the melting of aluminum due to high-temperature welding of steel in the prior art, improving the strength of the marine transition joint, ensuring the stable quality of the marine transition joint, and reducing the number of welds at the same time; on the other hand, the processing efficiency of the marine transition joint is improved.

[0008] In some embodiments, it further includes a support moving assembly; the grinding assembly, the cleaning assembly, and the friction stir additive manufacturing spindle are all installed on the support moving assembly, and the support moving assembly is used to be installed on the hull and drive the grinding assembly, the cleaning assembly, and the friction stir additive manufacturing spindle to move synchronously.

[0009] In some embodiments, the grinding assembly includes a steel brush, and the steel brush is used to rotatably grind the surface of the hull.

[0010] In some embodiments, the grinding assembly further includes a telescopic cylinder and a pressure detector. The telescopic cylinder is disposed between the steel brush and the pressure detector, and the pressure detector is disposed on the support moving assembly.

[0011] In some embodiments, the cleaning assembly includes a blowing gun, which is used to blow off the debris on the polished surface in a timely manner away from the friction stir additive manufacturing spindle.

[0012] In some embodiments, the support moving assembly includes a guide rail, a main shaft, and a gantry. The guide rail is used to be distributed on both lateral sides of the hull and fixed to the hull. The grinding assembly, the cleaning assembly, and the friction stir additive manufacturing spindle are all mounted on the main shaft. The main shaft is movably disposed vertically and horizontally on the gantry. The lower ends of both sides of the gantry are respectively supported on the guide rail correspondingly, and the gantry can move longitudinally along the guide rail.

[0013] In some embodiments, the guide rail is a magnetic pole guide rail, and an electromagnet is provided at the lower end of the gantry. The electromagnet is magnetically coupled with the magnetic pole guide rail to stably support the gantry above the magnetic pole guide rail.

[0014] In some embodiments, when the hull is a magnetic material hull, the magnetic pole guide rail is directly adsorbed on the front surface of the hull. When the hull is a non-magnetic material hull, the magnetic pole guide rail is fixed on the back surface of the hull. The longitudinal movement of the gantry on the magnetic pole guide rail is achieved by a traction device or the principle of magnetic levitation.

[0015] In some embodiments, the magnetic pole guide rail includes a plurality of electromagnets arranged in sequence longitudinally.

[0016] In some embodiments, the principle of magnetic levitation is as follows: when the gantry is stably supported on the magnetic pole guide rail by adsorption through the electromagnet, the magnetic poles of the plurality of electromagnets of the magnetic pole guide rail are changed by an electrical signal, so that the magnetic pole of the electromagnet directly below the electromagnet becomes the same as the magnetic pole of the electromagnet, and the magnetic poles of the electromagnets adjacent to the electromagnet directly below the electromagnet become opposite to the magnetic pole of the electromagnet, thereby forcing the gantry to move unidirectionally longitudinally.

[0017] In some embodiments, the magnetic pole guide rail further includes a packaging member, and the packaging member packages the plurality of electromagnets.

[0018] In some embodiments, rollers are further provided at the lower end of the gantry, and the rollers are rollably engaged with the guide rail.

[0019] In some embodiments, the magnetic pole guide rail is provided with a guide groove opening upward and extending longitudinally, and a first magnetic part of the guide rail and a second magnetic part of the guide rail located on both sides of the guide groove. The electromagnet includes a first magnetic part of the electromagnet and a second magnetic part of the electromagnet that are magnetically attracted and abutted against the first magnetic part of the guide rail and the second magnetic part of the guide rail respectively. The roller is arranged between the first magnetic part of the electromagnet and the second magnetic part of the electromagnet, and the roller protrudes downward from the first magnetic part of the electromagnet and the second magnetic part of the electromagnet.

Correspondingly, the grinding assembly grinds the surface of the hull, the cleaning assembly timely cleans the ground surface of the hull, and the friction stir additive main shaft performs in-situ additive manufacturing of an aluminum layer on the ground and cleaned surface of the hull.

[0023] Since the method for in-situ manufacturing of a marine transition joint in an embodiment of the present invention uses the in-situ manufacturing equipment for marine transition joints in an embodiment of the present invention, therefore, the method for in-situ manufacturing of a marine transition joint in an embodiment of the present invention has the same technical effects as the in-situ manufacturing equipment for marine transition joints in an embodiment of the present invention, which will not be elaborated here.

Detailed description of the specific implementation

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0034] The following will be combined with Figures 1 to 5 to describe the in-situ manufacturing equipment 1000 for marine transition joints of the embodiments of the present invention.

[0035] As Figures 1 to 3As shown, a marine transition joint in-situ manufacturing device 1000 according to an embodiment of the present invention includes a grinding assembly 1, a cleaning assembly 2, and a friction stir additive manufacturing spindle 3 that are sequentially arranged adjacent to each other and can move synchronously. For example, the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 are sequentially arranged adjacent to each other in the longitudinal direction. The cleaning assembly 2 is located between the grinding assembly 1 and the friction stir additive manufacturing spindle 3, and the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 can move synchronously in the longitudinal, transverse, and vertical directions. Through longitudinal movement, in-situ additive manufacturing on the steel surface of the hull 2000 is achieved. Through transverse movement, the additive manufacturing width on the steel surface of the hull 2000 is widened. Through vertical movement, the vertical height positions of the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 are adjusted. The grinding assembly 1 is used to grind the surface of the hull 2000 to remove pollutants such as oxide layers, grease, and rust on the steel surface of the hull 2000, obtaining a ground surface. The cleaning assembly 2 is used to clean the ground surface of the hull 2000 in a timely manner. Since the grinding assembly 1 and the cleaning assembly 2 are arranged adjacent to each other, it can be ensured that the cleaning assembly 2 timely removes the debris on the ground surface. The cleaning assembly 2 can clean the debris on the ground surface through cleaning methods such as blowing air and sweeping, making the ground surface clean, obtaining a ground and cleaned surface, so as to improve the effect of the aluminum layer additive manufactured by the subsequent friction stir additive manufacturing spindle 3 on the ground and cleaned surface and the adhesion between the aluminum layer and the steel surface. The friction stir additive manufacturing spindle 3 is used to perform in-situ additive manufacturing of an aluminum layer on the ground and cleaned surface of the hull 2000, that is, to process an aluminum layer on the steel surface of the hull 2000. The cleaning assembly 2 and the friction stir additive manufacturing spindle 3 are arranged adjacent to each other, which can ensure that the friction stir additive manufacturing spindle 3 can timely perform in-situ additive manufacturing of an aluminum layer on the ground and cleaned surface.

[0036] When the in-situ manufacturing device 1000 for marine transition joints in the embodiments of the present invention is in use, after adjusting the positions of the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 relative to the steel surface of the hull 2000 (such as by horizontal movement and vertical movement), the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 are synchronously moved (such as longitudinally). Correspondingly, the grinding assembly 1 grinds the surface of the hull 2000, the cleaning assembly 2 timely cleans the ground surface of the hull 2000, and the friction stir additive manufacturing spindle 3 performs in-situ additive manufacturing of an aluminum layer on the ground and cleaned surface of the hull 2000. Among them, during the movement along a path, in the initial movement stage, the grinding assembly 1 and the cleaning assembly 2 first grind and clean the initial position of the hull 2000, and the friction stir additive manufacturing spindle 3 does not perform additive manufacturing until the friction stir additive manufacturing spindle 3 moves to the ground and cleaned surface at the initial position, and then starts to perform additive manufacturing of the aluminum layer; in the subsequent continuous synchronous movement stage, the grinding assembly 1 grinds while moving, the cleaning assembly 2 cleans while moving, and the friction stir additive manufacturing spindle 3 performs in-situ additive manufacturing of the aluminum layer while moving. In the last movement stage, after the grinding assembly 1 and the cleaning assembly 2 complete the grinding and cleaning of the termination position of the hull 2000, the grinding assembly 1 stops the grinding action and the cleaning assembly 2 stops the cleaning action, while the friction stir additive manufacturing spindle 3 still continues to perform in-situ additive manufacturing of the aluminum layer until the manufacturing of the aluminum layer at the ground and cleaned surface of the termination position is completed. Thus, the processing of the aluminum layer for one path is completed; when the processing of the aluminum layer for one path is completed, the aluminum layer for another adjacent path can be completed until the aluminum layer is processed on the steel surface within the required range of the hull 2000.

[0037] By synchronously moving the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 while grinding, cleaning, and performing in-situ additive manufacturing of the aluminum layer on the steel surface of the hull 2000, the in-situ additive manufacturing of the aluminum layer on the steel surface of the hull 2000 is realized on the one hand, avoiding the low strength of the transition joint of the hull 2000 caused by the melting of aluminum due to high-temperature welding of steel in the prior art, improving the strength of the transition joint of the hull 2000, ensuring the stable quality of the transition joint of the hull 2000, and at the same time reducing the number of welds; on the other hand, the processing efficiency of the marine transition joint is improved.

[0038] In some embodiments, such as Figures 1 to 3As shown, it further includes a support moving component 4; the grinding component 1, the cleaning component 2, and the friction stir additive manufacturing spindle 3 are all installed on the support moving component 4. The support moving component 4 is used to be installed on the hull 2000 and drive the grinding component 1, the cleaning component 2, and the friction stir additive manufacturing spindle 3 to move synchronously. By setting the support moving component 4, the grinding component 1, the cleaning component 2, and the friction stir additive manufacturing spindle 3 can be installed adjacent to each other in sequence and driven to move synchronously, which is beneficial to conveniently realizing the synchronous movement of the grinding component 1, the cleaning component 2, and the friction stir additive manufacturing spindle 3 while grinding, cleaning, and in-situ additive manufacturing of the aluminum layer on the steel surface of the hull 2000.

[0039] In some embodiments, as Figure 1 shown, the grinding component 1 includes a steel brush 101, and the steel brush 101 is used to rotatably grind the surface of the hull 2000. By contacting the rotating steel brush 101 with the steel surface of the hull 2000, pollutants such as the oxide layer, grease, and rust on the steel surface of the hull 2000 can be effectively removed.

[0040] In some embodiments, the grinding component 1 further includes a telescopic cylinder 102 and a pressure detector 103. The telescopic cylinder 102 is arranged between the steel brush 101 and the pressure detector 103, and the pressure detector 103 is arranged on the support moving component 4. When the steel brush 101 rotates to grind the steel surface of the hull 2000, the pressure detector 103 collects the grinding pressure. If the grinding pressure is small, the steel surface of the hull 2000 is not sufficiently ground. At this time, the telescopic cylinder 102 extends and moves towards the steel surface of the hull 2000 to increase the grinding pressure and improve the grinding effect; if the grinding pressure is large, the steel surface of the hull 2000 is over-ground. At this time, the telescopic cylinder 102 retracts and moves away from the steel surface of the hull 2000.

[0041] Optionally, the telescopic cylinder 102 can be an electric cylinder or a pneumatic cylinder, etc. The pressure detector 103 can be a pressure sensor.

[0042] In some embodiments, the cleaning component 2 includes a blowing gun 201, and the blowing gun 201 is used to timely blow off the debris on the ground surface away from the friction stir additive manufacturing spindle 3 to ensure that the ground surface is clean and prevent the debris from entering the aluminum layer.

[0043] Optionally, the blowing gun 201 is a compressed air gun.

[0044] In some embodiments, as Figures 1 to 5As shown, the support moving component 4 includes a guide rail 401, a main shaft 402, and a gantry 403; the guide rail 401 is used to be distributed on the transverse sides of the hull 2000 and fixed to the hull 2000. The grinding component 1, the cleaning component 2, and the friction stir additive main shaft 3 are all installed on the main shaft 402 in sequence longitudinally. For example, they are installed at the lower end of the main shaft 402. The main shaft 402 is arranged on the gantry 403 so as to be movable vertically and horizontally. The vertical movement and horizontal movement of the main shaft 402 can be achieved by common technologies. For example, the vertical movement of the main shaft 402 can be driven by a first motor 4021, and the horizontal movement of the main shaft 402 can be driven by a second motor (not shown in the figure). The lower ends of both sides of the gantry 403 are respectively supported on the guide rail 401 correspondingly, and the gantry 403 can move longitudinally along the guide rail 401; through the cooperation of the gantry 403 and the guide rail 401, the gantry 403 can be stably located above the hull 2000. At the same time, the gantry 403 can move longitudinally along the guide rail 401, so that the grinding component 1, the cleaning component 2, and the friction stir additive main shaft 3 can be synchronously moved while grinding, cleaning, and in-situ additive manufacturing of an aluminum layer on the steel surface of the hull 2000. When the aluminum layer processing of a path is completed longitudinally, the grinding component 1, the cleaning component 2, and the friction stir additive main shaft 3 can be synchronously moved horizontally to an adjacent another path by the horizontal movement of the main shaft 402, and then the aluminum layer of the adjacent another path is completed until the aluminum layer is processed on the steel surface of the required range of the hull 2000.

[0045] In some embodiments, the guide rail 401 is a magnetic pole guide rail 4011, and an electromagnet 4031 is provided at the lower end of the gantry 403. The electromagnet 4031 is magnetically coupled with the magnetic pole guide rail 4011 so that the gantry 403 is stably supported above the magnetic pole guide rail 4011. In this way, it is convenient to install the gantry 403 on the hull 2000, and it is beneficial to improve the quality of the in-situ additive manufacturing of the aluminum layer.

[0046] In some embodiments, when the hull 2000 is a magnetic material hull, the magnetic pole guide rail 4011 is directly adsorbed on the front of the hull 2000 (as Figure 5 shown), which is convenient for fixing. When the hull 2000 is a non-magnetic material hull 2000, the magnetic pole guide rail 4011 is fixed on the back of the hull 2000 (as Figure 3 shown), that is, the magnetic pole guide rail 4011 is fixed to the back of the hull 2000, which is convenient for fixing. The longitudinal movement of the gantry 403 on the magnetic pole guide rail 4011 is achieved by a traction device (not shown in the figure) or the principle of magnetic levitation (as Figure 4It is realized as shown in the figure. By means of a traction device such as a traction rope, the gantry 403, the electromagnet 4031, the grinding assembly 1, the cleaning assembly 2 and the friction stir additive manufacturing spindle 3 are synchronously longitudinally moved together, or the guiding gantry 403, the electromagnet 4031, the grinding assembly 1, the cleaning assembly 2 and the friction stir additive manufacturing spindle 3 are synchronously longitudinally moved together by the magnetic levitation principle between the electromagnet 4031 and the magnetic pole guide 4011.

[0047] In some embodiments, such as Figure 3 and Figure 4 shown, the magnetic pole guide 4011 includes a plurality of electromagnets 40111 arranged in sequence longitudinally.

[0048] In some embodiments, such as Figure 4 shown, the magnetic levitation principle is as follows: when the gantry 403 is adsorbed by the electromagnet 4031 and the magnetic pole guide 4011 and stably supported on the magnetic pole guide 4011, by controlling the pole change of the plurality of electromagnets 40111 of the magnetic pole guide 4011 through an electrical signal, the pole of the electromagnet 40111 directly below the electromagnet 4031 is changed to be the same as the pole of the electromagnet 4031, and the poles of the electromagnets 40111 adjacent to the electromagnet 40111 directly below the electromagnet 4031 are changed to be opposite to the pole of the electromagnet 4031, so as to force the gantry 403 to move unidirectionally longitudinally.

[0049] In some embodiments, such as Figure 4 shown, the magnetic pole guide 4011 further includes a packaging member 40112. The packaging member 40112 can be a resin member. The packaging member 40112 packages the plurality of electromagnets 40111 and fixes the plurality of longitudinally arranged electromagnets 40111 together. The plurality of longitudinally arranged electromagnets 40111 can also be fixed by other means instead of using the packaging member 40112.

[0050] In some embodiments, such as Figure 2 shown, a roller 4032 is further provided at the lower end of the gantry 403. The roller 4032 is rollably engaged with the guide rail 401, which can make the gantry 403 move longitudinally smoothly and stably.

[0051] In some embodiments, the magnetic pole guide 4011 is provided with a guide groove opening upward and extending longitudinally, and a first magnetic part of the guide rail and a second magnetic part of the guide rail located on both sides of the guide groove. The electromagnet 4031 includes an electromagnet first magnetic part 40311 and an electromagnet second magnetic part 40312 that are respectively magnetically attracted and abutted against the first magnetic part of the guide rail and the second magnetic part of the guide rail. The roller 4032 is arranged between the electromagnet first magnetic part 40311 and the electromagnet second magnetic part 40312, and the roller 4032 protrudes downward from the electromagnet first magnetic part 40311 and the electromagnet second magnetic part 40312. Thus, the gantry 403 can move longitudinally smoothly and stably.

[0052] Optionally, the electromagnet 4031 is in a U shape with the opening facing downward, that is, the lower ends of the first magnetic part 40311 and the second magnetic part 40312 of the electromagnet are separated from each other and the upper ends are connected to each other.

[0053] Optionally, the upper surfaces of the first magnetic part of the guide rail and the second magnetic part of the guide rail are flush, and the lower surfaces of the first magnetic part 40311 and the second magnetic part 40312 of the electromagnet are flush.

[0054] It should be noted that the above-mentioned wire brush 101 and the rotational movement of the friction stir additive manufacturing spindle 3 can be independently driven respectively, or can be synchronously driven by the rotation of the spindle 402.

[0055] The present invention also proposes a method for in-situ manufacturing of a marine transition joint.

[0056] According to the method for in-situ manufacturing of a marine transition joint in an embodiment of the present invention, the surface of the hull 2000 is in-situ additively manufactured with an aluminum layer by using the above-mentioned in-situ manufacturing equipment 1000 for a marine transition joint in an embodiment of the present invention, including the following steps:

[0057] After adjusting the positions of the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 relative to the steel surface of the hull 2000, the grinding assembly 1, the cleaning assembly 2, and the friction stir additive manufacturing spindle 3 are moved synchronously. Correspondingly, the grinding assembly 1 grinds the surface of the hull 2000, the cleaning assembly 2 timely cleans the ground surface of the hull 2000, and the friction stir additive manufacturing spindle 3 in-situ additively manufactures an aluminum layer on the ground and cleaned surface of the hull 2000. Among them, during the movement along a path, in the initial movement stage, the grinding assembly 1 and the cleaning assembly 2 first grind and clean the initial position of the hull 2000, and the friction stir additive manufacturing spindle 3 does not additively manufacture until the friction stir additive manufacturing spindle 3 moves to the ground and cleaned surface of the initial position, and then starts to additively manufacture the aluminum layer; in the subsequent continuous synchronous movement stage, the grinding assembly 1 grinds while moving, the cleaning assembly 2 cleans while moving, and the friction stir additive manufacturing spindle 3 in-situ additively manufactures the aluminum layer while moving. In the final movement stage, after the grinding assembly 1 and the cleaning assembly 2 complete the grinding and cleaning of the termination position of the hull 2000, the grinding assembly 1 stops the grinding action and the cleaning assembly 2 stops the cleaning action, while the friction stir additive manufacturing spindle 3 still continues to in-situ additively manufacture the aluminum layer until the aluminum layer manufacturing at the ground and cleaned surface of the termination position is completed. Thus, the aluminum layer processing of one path is completed; when the aluminum layer processing of one path is completed, the aluminum layer of an adjacent another path can be completed until the aluminum layer is processed on the steel surfaces within the required range of the hull 2000.

[0058] Since the in-situ manufacturing method of the marine transition joint according to the embodiment of the present invention uses the in-situ manufacturing device 1000 of the marine transition joint according to the embodiment of the present invention, therefore, the in-situ manufacturing method of the marine transition joint according to the embodiment of the present invention has the same technical effects as the in-situ manufacturing device 1000 of the marine transition joint according to the embodiment of the present invention, which will not be elaborated herein.
