Description

Technical Field

[0001] The invention belongs to the technical field of ship parts processing, in particular to a ship arc-shaped plate painting device. Background Art

[0002] Ships are made up of thousands of parts and are related to almost every industrial sector. In addition to the unique hull construction technology, shipbuilding also involves various fields such as machinery, electrical engineering, metallurgy, construction, chemistry and even arts and crafts. When preparing the panels on the outer surface of the ship, the panels need to be painted to improve their anti-corrosion properties.

[0003] The panels of a ship include curved panels. When painting curved panels, paint mist is sprayed onto the surface of the curved panel through the nozzle of the paint spraying equipment. During this process, the nozzle moves at a constant speed and the paint mist adheres to the surface of the curved panel. However, the paint mist sprayed from the nozzle will dissipate into the air, and the dissipated paint mist will adhere to the painted part of the panel again. Therefore, there are differences in the thickness of the paint surface at different positions, which affects the quality of painting. In addition, when the nozzle moves in a straight line to spray paint mist onto the curved surface of the curved panel, there are differences in the uniformity of the paint spraying on the curved surface, which also affects the quality of painting.

[0004] To this end, the present invention provides a painting device for arc-shaped panels of ships. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a ship curved plate painting device described in the present invention comprises a workbench, a paint spraying platform is provided on the top surface of the workbench, clamping members are provided on both sides of the paint spraying platform, a fixing frame is provided above the paint spraying platform, a support frame is provided between the fixing frame and the workbench, a pair of slide grooves are provided on the top surface of the fixing frame, a slider is slidably connected in the slide groove, a pair of curved limiting plates are provided inside the fixing frame, the center points of the pair of curved limiting plates are the same point, a connecting frame is provided between the curved limiting plates and the slider, a receiving block is provided between the two curved limiting plates, and an arc adjustment component is installed on the outside of the curved limiting plates, and the arc adjustment component is used to adjust the curvature of the curved limiting plates;

[0007] The supporting block is respectively connected to rollers on both sides close to the arc-shaped limit plate, and a slide rail adapted for the roller is provided inside the arc-shaped limit plate, and the roller is rotatably connected to the slide rail, and a connecting rod is installed on the bottom surface of the supporting block, and a supporting plate is installed on the bottom end of the connecting rod, and a pair of isolation plates are provided on the vertical surface of the supporting plate, and a spray hole is provided on the vertical surface of the supporting plate and located between the two isolation plates, and a plurality of nozzles are evenly installed on the end surface of the isolation plate; the arc-shaped plate is labeled S in the drawings of the specification of the present invention. When the embodiment of the present invention is used, the worker can first place the arc-shaped plate to be processed on one side of the arc-shaped limit plate with the assistance of equipment or manually, so that one side faces the nozzle, and Then adjust the position of the arc plate so that its center is at the same point as the center of the arc limit plate, and fix the arc plate on the paint spraying table through the clamping parts. It should be noted that before processing, the staff should adjust the curvature of the arc limit plate through the curvature adjustment component in advance to make it compatible with the workpiece to be processed, and then start the drive motor to make it move to drive the roller to rotate, and then roll along the slide rail, thereby driving the receiving block to perform uniform circular motion along the arc limit plate. It should be noted that two drive motors are set to keep the angular velocity on both sides of the receiving block consistent, avoiding the influence of friction between the receiving block and the arc limit plate. In this process, the receiving block drives the receiving block through the connecting rod The connecting plate moves along the curvature of the arc-shaped limiting plate. It should be noted that, in specific use, it is necessary to select connecting plates of different types according to the specifications of the plate, and it is necessary to ensure that the height of the spray hole on the connecting plate is the same as the height of the arc-shaped plate. The arc-shaped plate is installed by the clamping part so that the arc-shaped plate is close to the spray hole on the connecting plate. When the connecting block moves, since the center of the plate and the arc-shaped limiting plate are at the same point, the movement trajectory of the connecting block is adjusted so that its movement trajectory is consistent with the angle of the arc-shaped plate. Therefore, the connecting plate is driven to move the spray hole along the curvature of the arc-shaped plate. The spray hole is always aligned with the arc-shaped plate and the relative position remains unchanged. It should be noted that the embodiment of the present invention needs to connect the nozzle to the external protective paint through a hose before use. The pumping device is connected, and the hose needs to be of sufficient length to facilitate the movement and spraying of the nozzle. In this way, during the movement of the receiving plate, the protective paint pumping component is turned on and operated to pump the protective paint into the nozzle, and finally sprayed out after being atomized. When the receiving plate drives the nozzle hole to move, the spraying assembly connected to the nozzle through the hose is started, and the paint mist sprayed from the nozzle covers the curved plate through the spray hole opened on the receiving plate. The receiving plate moves at a uniform speed along the arc on the curved plate and stops after the curved plate is painted. In this process, the isolation plate will limit the escape of paint mist to prevent the curved plate from being partially covered by the escaped paint mist again after being painted, resulting in differences in the overall paint surface of the curved plate, thereby ensuring the quality of painting.In addition, the curved limit plate and the curved plate have the same curvature. When the connecting block between the two curved limit plates moves, the connecting plate is driven to move along the curved plate through the connecting rod, and the distance between the connecting plate and the curved plate remains stable. When the curved plate is being painted, the spray hole continues to maintain the same angle with the position to be painted, ensuring the uniformity of the paint spraying and further ensuring the quality of the paint spraying. After spraying one side of the curved plate, it is installed to the other side of the curved limit plate. Then, the curvature of the pair of curved limit plates is adjusted by the curvature adjustment component so that the curved plate and the curved limit plates are once again kept in the same circle center state. Then, the connecting plate is removed, the nozzle position is reversed, and the above steps are repeated to complete the double-sided spraying operation.

[0008] Preferably, the top surface and the top surface of the receiving block are provided with a cover plate, and the cover plate is slidably connected to the upper and lower end surfaces of the arc-shaped limiting plate; when the receiving block moves, the cover plates at the upper and lower ends of the receiving block will limit the angle of the receiving block to prevent the receiving block from deflecting when the receiving block is pulled by the pull rope.

[0009] Preferably, the curvature adjustment assembly includes a connecting piece, which is arranged between the two curved limit plates, and the curved limit plates are provided with an adjusting rod, and the adjusting rod is connected in series with a telescopic rod; when in use, the connecting piece fixes the two curved limit plates to maintain integrity, and when painting panels with different curvatures, the length of the telescopic rod is adjusted, the overall length of the adjusting rod is adjusted, and the adjusting rod pulls the curved limit plate to change the bending curvature, so that the curvature of the curved limit plate is the same as the curvature of the curved plate to be painted. In this process, it is necessary to first disassemble the connecting frame, and then install it according to the position of the curved limit plate or replace the size of the connecting frame for installation, thereby improving the overall scope of application of the curved limit plate; it should be noted that when the embodiment of the present invention is used specifically, it is necessary to select a suitable processing plate according to the height of the curved limit plate and the adjusting rod to avoid the situation where the adjusting rod affects the external workpiece.

When the surface of the isolation piece bears too much paint mist, it can be disassembled and cleaned.

[0011] Preferably, a rectangular hole is opened on the uppermost inner wall of the spray hole, and a regulating plate is inserted into the rectangular hole; by adjusting the position of the regulating plate inserted into the spray hole, the height of the spray hole can be limited, making the spray hole suitable for spraying paint on curved panels of various heights.

[0012] Preferably, the end of the clamping member is connected to a hydraulic output assembly, and a sensor that can detect the clamping force is installed in the hydraulic output assembly; when the clamping member clamps and fixes the curved plate, the sensor in the hydraulic output assembly detects the clamping force and adjusts it to prevent the curved plate from being excessively clamped and deformed, resulting in a change in curvature, which affects the painting effect.

[0014] Preferably, the plug-in blocks are made of magnetic material; when removing the plug-in blocks, multiple plug-in blocks can be quickly attracted out of the through hole by magnets, which facilitates the disassembly of the positioning rod; this solution does not use magnetic interference materials.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1: Figures 1 to 5 As shown, a painting device for curved plate members of a ship according to an embodiment of the present invention includes a workbench 1, a painting platform 11 is provided on the top surface of the workbench 1, clamping members 12 are provided on both sides of the painting platform 11, a fixed frame 2 is provided above the painting platform 11, a support frame is provided between the fixed frame 2 and the workbench 1, a pair of slide grooves are provided on the top surface of the fixed frame 2, a slider 21 is slidably connected in the slide groove, a pair of curved limiting plates 23 with the same curvature as the curved plate are provided in the fixed frame 2, a connecting frame 22 is provided between the curved limiting plate 23 and the slider 21, and a receiving block 24 is provided between the two curved limiting plates 23;

[0035] The receiving block 24 is rotatably connected to the two sides of a pair of arc-shaped limit plates 23. A slide rail adapted to the roller 241 is provided inside the arc-shaped limit plate 23. The roller 241 is in rolling connection with the slide rail. A winding wheel 25 is installed on the bottom surface of the fixed frame 2. The top surface of the winding wheel 25 is provided with a motor output end. A pull rope is provided between the winding wheel 25 and the receiving block 24. A connecting rod 26 is installed on the bottom surface of the receiving block 24. A receiving plate 27 is installed at the bottom end of the connecting rod 26. A pair of isolation plates 28 are provided on the vertical surface of the receiving plate 27. A spray hole is provided on the vertical surface of the receiving plate 27 and is located between the two isolation plates 28 to isolate A plurality of nozzles 29 are evenly installed on the end surface of the plate 28; the plate parts of the ship include curved plate parts. When painting the curved plate parts, the paint mist is sprayed onto the surface of the curved plate parts through the nozzles 29 of the painting equipment. In this process, the nozzles 29 move at a constant speed, and the paint mist adheres to the surface of the curved plate parts. However, the paint mist sprayed by the nozzles 29 will escape into the air and then adhere to the painted part of the plate parts again. Therefore, the thickness of the paint surface at different positions will vary, affecting the quality of painting. In addition, when the nozzles 29 move linearly to spray the paint mist onto the curved surface of the curved plate parts, the uniformity of the paint spraying on the curved surface will vary, which will also affect the quality of painting.

[0036] In the drawings of the present invention, the curved plate is labeled S. When the embodiment of the present invention is in use, the worker can first place the curved plate to be processed on one side of the curved limit plate 23 with the assistance of equipment or manually, so that one side faces the nozzle 29, and then adjust the position of the curved plate so that its center is at the same point as the center of the curved limit plate 23, and fix the curved plate on the paint spraying table 11 through the clamping member 12. It should be noted that before processing, the staff should adjust the curvature of the curved limit plate 23 in advance through the curvature adjustment component to make it compatible with the workpiece to be processed, and then start the drive motor to make it move to drive the roller 25 to rotate, and then roll along the slide rail, thereby driving the receiving block 24 to move along the curved limit The positioning plate 23 performs uniform circular motion. It should be noted that two driving motors are provided to keep the angular velocity of the two sides of the receiving block 24 consistent, avoiding the influence of the friction between the receiving block 24 and the arc-shaped limiting plate 23. In this process, the receiving block 24 drives the receiving plate 27 to move along the curvature of the arc-shaped limiting plate 23 through the connecting rod 26. It should be noted that in specific use, different types of receiving plates 27 need to be selected according to the specifications of the plate. It is necessary to ensure that the height of the spray hole on the receiving plate 27 is the same as the height of the arc-shaped plate. The arc-shaped plate is installed by the clamping member 12 so that the arc-shaped plate is close to the spray hole on the receiving plate 27. When the receiving block 24 moves, since the center of the plate and the arc-shaped limiting plate 23 are at the same point, the receiving block 24 can be adjusted in this way. The movement trajectory of the connecting block 24 makes its movement trajectory consistent with the angle of the arc-shaped plate, so the connecting plate 27 is driven to move the spray hole along the curvature of the arc-shaped plate, and the spray hole is always aligned with the arc-shaped plate and the relative position remains unchanged. It should be noted that before use, the embodiment of the present invention needs to connect the nozzle 29 with the external protective paint pumping device through a hose, and at the same time, the hose needs to be reserved with sufficient length to facilitate the movement and spraying of the nozzle 29. In this way, during the movement of the connecting plate 27, the protective paint pumping assembly is turned on at the same time to make it run to pump the protective paint into the nozzle 29, and finally sprayed out after being atomized by 29. During the process of the connecting plate 27 driving the spray hole to move, the nozzle 29 is started through the hose to connect the paint spraying assembly, and the paint mist sprayed by the nozzle 29 passes through the connecting plate 2 The spray holes opened on 7 cover the curved plate, and the receiving plate 27 moves at a uniform speed along the arc on the curved plate, and stops after the curved plate is painted. In this process, the isolation plate 28 will limit the escape of paint mist, preventing the curved plate from being partially covered by the escaped paint mist again after being painted, resulting in differences in the overall paint surface of the curved plate, thereby ensuring the quality of painting; in addition, the curved limiting plate 23 has the same curvature as the curved plate, and the receiving block 24 between the two curved limiting plates 23 moves when the receiving block 24 drives the receiving plate 27 to move along the curved plate through the connecting rod 26, and the distance between the receiving plate 27 and the curved plate remains stable. When the curved plate is painted, the spray hole continues to maintain the same angle with the position to be painted, thereby ensuring the uniformity of painting and further ensuring the quality of painting;After spraying one side of the curved plate, it is installed on the other side of the curved limit plate 23. The curvature of the curved limit plates 23 is then adjusted using the curvature adjustment assembly to keep the curved plate and the curved limit plates 23 aligned at the same center. The receiving plate 27 is then removed, the nozzle 29 is adjusted, and the plate is reinstalled. The above steps are repeated to complete the double-sided spraying operation.

[0037] like Figure 4 As shown, the top surface and top surface of the receiving block 24 are provided with a cover plate 3, and the cover plate 3 is slidably connected to the upper and lower end surfaces of the arc-shaped limiting plate 23; when the receiving block 24 moves, the cover plates 3 at the upper and lower ends of the receiving block 24 will limit the angle of the receiving block 24, avoiding the deflection of the receiving block 24 when being pulled by the pull rope, thereby ensuring the stability of the movement of the receiving block 24.

[0038] like Figure 3 As shown, the curvature adjustment assembly includes a connecting piece 4, which is arranged between the two curved limit plates 23. The curved limit plates 23 are provided with an adjusting rod 5, and the adjusting rod 5 is connected in series with a telescopic rod 51. When in use, the connecting piece 4 fixes the two curved limit plates 23 to maintain integrity. When painting panels with different curvatures, the length of the telescopic rod 51 is adjusted, and the overall length of the adjusting rod 5 is adjusted. The adjusting rod 5 pulls the curved limit plate 23 to change the bending curvature, so that the curvature of the curved limit plate 23 is the same as the curvature of the curved panel to be painted. In this process, the connecting piece 4 needs to be connected first. The frame 22 is disassembled, and then the connecting frame 22 is installed according to the position of the arc limit plate 23 or the size of the connecting frame 22 is replaced for installation, thereby improving the overall application range of the arc limit plate 23; it should be noted that when the embodiment of the present invention is used in a specific way, it is necessary to select a suitable processing plate according to the height of the arc limit plate 23 and the adjusting rod 5 to avoid the situation where the adjusting rod 5 affects the external workpiece, and the connecting member 4 is used to keep the curvature of a pair of arc limit plates 23 changing synchronously when adjusting the curvature of the arc limit plate 23 so that the center of the pair of arc limit plates 23 always remains at the same point.

[0039] like Figure 6 As shown, an isolation piece 6 is inserted into the spray hole, and the isolation piece 6 makes the receiving plate 27 and the isolation plate 28 bear the part of the paint mist sprayed out by the nozzle 29; when in use, the isolation piece 6 is embedded in the spray hole opened in the receiving plate 27, and when the nozzle 29 sprays the paint mist, the isolation piece 6 will isolate the paint mist from the surface of the receiving plate 27 and the isolation plate 28. When the surface of the isolation piece 6 bears too much paint mist, it can be disassembled and cleaned, which is more convenient than cleaning the receiving plate 27 and the isolation plate 28.

[0040] A rectangular hole is provided on the uppermost inner wall of the spray hole, into which a regulating plate 7 is inserted. By adjusting the position of the regulating plate 7 inserted into the spray hole, the height of the spray hole can be limited, making the spray hole suitable for spraying paint on curved panels of various heights, thereby improving the applicable range of the receiving plate 27.

[0041] like Figure 1 As shown, the end of the clamping member 12 is connected to a hydraulic output assembly, and a sensor that can detect the clamping force is installed in the hydraulic output assembly; when the clamping member 12 clamps the fixed curved plate, the sensor in the hydraulic output assembly detects the clamping force and adjusts it to prevent the curved plate from being excessively clamped and deformed, resulting in a change in curvature, which affects the painting effect.

[0042] like Figures 8 and 9 As shown, the surface of the arc-shaped limiting plate 23 is evenly provided with through holes, in which a plug-in block 91 is inserted, and a positioning rod 9 is provided at the end of the plug-in block 91; when in use, when adjusting the position of the arc-shaped plate on the paint spraying table 11, the plug-in block 91 is inserted into the through hole, and the positioning rod 9 on the plug-in block 91 will be arranged to form an arc structure. By placing the arc-shaped plate against the arc structure, the arc-shaped plate can be quickly positioned, thereby optimizing the arc-shaped plate painting process.

[0043] The plug-in blocks 91 are made of magnetic material. When the plug-in blocks 91 are removed, multiple plug-in blocks 91 can be quickly attracted out of the through hole by magnets, which facilitates the disassembly of the positioning rod 9. This solution does not use magnetic interference materials.

[0044] Example 2: Figure 10 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a fixed plate 10 is provided on the top surface of the workbench 1, and a guide rod 101 is evenly inserted on the vertical surface of the fixed plate 10, and the end of the guide rod 101 is connected to the output end of the hydraulic assembly, and a first rubber strip 102 is provided on the end of the guide rod 101 close to the spray painting table 11, and a vertical rod 103 is evenly provided on the top surface of the first rubber strip 102; when in use, the top height of the vertical rod 103 is less than the position height of the fixed frame 2, which can avoid the structure on the fixed frame 2 blocking the movement of the vertical rod 103, and the arc limit is adjusted by the curvature of the arc plate. When the curvature of the positioning plate 23 is adjusted, the hydraulic assembly connected to the guide rod 101 is started, and the guide rod 101 drives the first rubber strip 102 to squeeze the curved surface of the curved plate. The first rubber strip 102 is deformed and attached to the curved surface of the curved plate. The vertical rod 103 on its top surface will form an arc structure with the same curvature as the curved plate. The top of the vertical rod 103 is attached to the curved limiting plate 23. When adjusting the curvature of the curved limiting plate 23, the curved structure can be used as a reference to improve the accuracy of adjusting the curvature of the curved limiting plate 23. It should be noted that the structure at the position of the curved plate needs to be disassembled during use to avoid blocking the attachment of the vertical rod 103.

[0045] like Figures 10 and 11 As shown, an embedding groove is provided at the top of the vertical rod 103, and a second rubber strip 104 is provided in the embedding groove; the vertical rod 103 will further present an arc structure through the second rubber strip 104 embedded in the groove, and the second rubber strip 104 will further present an arc structure, which can further assist in the process of adjusting the curvature of the arc limiting plate 23.

[0046] When the embodiment of the present invention is in use, the worker can first place the arc-shaped plate to be processed on one side of the arc-shaped limiting plate 23 with the assistance of equipment or manually, so that one side of it faces the nozzle 29, and then adjust the position of the arc-shaped plate so that its center of circle is at the same point as the center of circle of the arc-shaped limiting plate 23, and fix the arc-shaped plate on the paint spraying table 11 through the clamping member 12. It should be noted that before processing, the staff should adjust the curvature of the arc-shaped limiting plate 23 in advance through the curvature adjustment component to make it compatible with the workpiece to be processed, and then start the driving motor to make it move to drive the roller 25 to rotate, and then roll along the slide rail, thereby driving the receiving block 24 to perform uniform circular motion along the arc-shaped limiting plate 23. It should be noted that Yes, two driving motors are set up to keep the angular velocity on both sides of the receiving block 24 consistent, avoiding the influence of the friction between the receiving block 24 and the arc-shaped limit plate 23. In this process, the receiving block 24 drives the receiving plate 27 to move along the curvature of the arc-shaped limit plate 23 through the connecting rod 26. It should be noted that in specific use, different types of receiving plates 27 need to be selected according to the specifications of the plate. It is necessary to ensure that the height of the spray hole on the receiving plate 27 is the same as the height of the arc-shaped plate. The arc-shaped plate is installed by the clamping member 12 so that the arc-shaped plate is close to the spray hole on the receiving plate 27. When the receiving block 24 moves, since the center of the plate and the arc-shaped limit plate 23 are at the same point, the movement trajectory of the receiving block 24 is adjusted so that its movement trajectory The angle of the receiving plate 27 is consistent with that of the curved plate, so the receiving plate 27 is driven to move the spray hole along the curvature of the curved plate, and the spray hole is always aligned with the curved plate and the relative position remains unchanged. It should be noted that before use, the embodiment of the present invention needs to connect the nozzle 29 with the external protective paint pumping device through a hose, and at the same time, the hose needs to be of sufficient length to facilitate the movement and spraying of the nozzle 29. In this way, during the movement of the receiving plate 27, the protective paint pumping assembly is opened at the same time to enable it to run and pump the protective paint into the nozzle 29, and finally sprayed out after being atomized through 29. When the receiving block 24 moves, the cover plates 3 at the upper and lower ends of the receiving block 24 will limit the angle of the receiving block 24 to prevent the receiving block 24 from being deflected when being pulled by the pull rope, thereby ensuring that the receiving block 24 moves smoothly. Dynamic stability; It should be noted that, when the embodiment of the present invention is used in detail, it is necessary to select a suitable processing plate according to the height of the arc limit plate 23 and the adjusting rod 5 to avoid the situation where the adjusting rod 5 affects the external workpiece. The connecting member 4 is used to keep the curvature of a pair of arc limit plates 23 changing synchronously when adjusting the curvature of the arc limit plate 23 so that the center of the pair of arc limit plates 23 is always kept at the same point; wherein the isolation member 6 is embedded in the spray hole opened by the receiving plate 27, and when the nozzle 29 sprays paint mist, the isolation member 6 will isolate the paint mist from the surface of the receiving plate 27 and the isolation plate 28. When the surface of the isolation member 6 bears too much paint mist, it can be disassembled and cleaned, which is more convenient than cleaning the receiving plate 27 and the isolation plate 28.

[0047] When in use, the height of the spray hole can be limited by adjusting the position of the regulating plate 7 inserted into the spray hole, so that the spray hole is suitable for painting curved panels of various heights, thereby improving the application range of the receiving plate 27; when the clamping member 12 clamps and fixes the curved panel, the sensor in the hydraulic output assembly detects the clamping force and adjusts it to prevent the curved panel from being excessively clamped and deformed, resulting in a change in the curvature, which affects the painting effect; when in use, when adjusting the position of the curved panel on the paint spraying table 11, the plug-in block 91 is inserted into the through hole, and the positioning rod 9 on the plug-in block 91 will be arranged to form an arc structure, and the curved panel can be quickly positioned by placing it against the arc structure; when removing the plug-in block 91, multiple plug-in blocks 91 can be quickly attracted out of the through hole by a magnet, which facilitates the disassembly of the positioning rod 9; this solution does not use magnetic interference materials.

[0048] When in use, the top height of the vertical rod 103 is less than the position height of the fixed frame 2, which can prevent the structure on the fixed frame 2 from blocking the movement of the vertical rod 103. When the curvature of the arc limit plate 23 is adjusted by the curvature of the arc plate, the hydraulic assembly connected to the guide rod 101 is started, and the guide rod 101 drives the first rubber strip 102 to squeeze the curved surface of the arc plate. The first rubber strip 102 is deformed and attached to the curved surface of the arc plate, and the vertical rod 103 on its top surface will form an arc structure with the same curvature as the arc plate. The top of the vertical rod 103 is attached to the arc limit plate 23, and the arc structure can be used as a reference when adjusting the curvature of the arc limit plate 23; the vertical rod 103 will further present an arc structure through the second rubber strip 104 embedded in the groove, and the second rubber strip 104 will further present an arc structure, which can further assist in the process of adjusting the curvature of the arc limit plate 23.
