In order to improve the durability and reliability of engineering parts and extend their service life, coating and protective treatment of the parts surface has become an indispensable link.

[0003] Traditional methods of coating engineering parts rely on manual operation, such as workers holding spray guns to spray paint on parts one by one. This method has many disadvantages: First, manual operation is difficult to ensure the uniformity of paint coating, and inconsistent paint layer thickness is prone to occur, resulting in insufficient protection in some areas, and paint accumulation in some areas affects the assembly accuracy of parts. Secondly, manual coating is inefficient, and it is difficult to meet the needs of rapid production for the large number of parts required for large-scale railway construction, which seriously restricts the progress of the project. Furthermore, in the cleaning of parts before coating, manual cleaning is often not thorough enough, and residual dust, oil and other impurities will affect the adhesion between the paint and the surface of the parts, reduce the coating quality, and thus affect the protective effect of the parts.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings of the specification 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.

[0022] Example: Please refer to the attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides a surface coating device for engineering parts used in railway construction, such as Figure 1As shown, the base 1 includes a base 1, which serves as the supporting foundation of the entire device and provides a stable installation platform for other components. The outer side of the top thereof is fixedly connected to a workbench 3 through a plurality of support rods 2. The support rods 2 are evenly distributed between the base 1 and the workbench 3 to ensure that the workbench 3 can be stably fixed at a certain height. A loading port 4 is provided on the front side of the upper surface of the workbench 3. The loading port 4 is designed to facilitate the staff to place the engineering parts to be coated with paint in the device to start the subsequent processing process. A special upper and lower mechanism or manual loading and unloading can be installed. A coating chamber 9 is fixedly connected to the rear side of the upper surface of the workbench 3. A coating groove 10 is provided in the middle of the coating chamber 9. The four inner side walls of the coating groove 10 are carefully provided with coating Cavity 11, the inner wall of the coating cavity 11 is movably installed with a short shaft 12 through a precise installation structure, the inner end of the short shaft 12 is firmly fixedly connected with a cross brush plate 13, and these cross brush plates 13 play a key role in the subsequent coating work, a drying chamber 20 is fixedly installed on the right side of the upper surface of the workbench 3, a drying trough 21 is opened in the middle of the drying chamber 20, and an electric heater 22 is precisely fixedly installed on the inner bottom of the drying chamber 20 to provide the heat required for drying the parts, a cylinder 32 is movably installed in the middle of the top of the workbench 3, and a lifting rod 34 is flexibly and movably installed inside the cylinder 32, and four cross frames 40 are evenly and fixedly connected to the top of the lifting rod 34, which provides a multi-directional support structure for subsequent operations on the parts.

[0023] In this embodiment, a cleaning port 5 is opened on the left side of the upper surface of the workbench 3, and a first rotating shaft 6 is movably installed at a position below the top of the base 1 near the cleaning port 5. The first rotating shaft 6 is installed on the base 1 through a high-precision bearing structure to ensure that it can rotate flexibly. A chuck 7 is fixedly installed on the top of the chuck 7. The chuck 7 is made of a strong and stable material, and cleaning brushes 8 are fixedly connected on both sides of the top of the chuck. The bristles of the cleaning brush 8 are made of a material suitable for cleaning dust and dirt on the surface of engineering parts, and have good wear resistance and cleaning effects.

[0024] Specifically, the first motor 29 is started, and the second active bevel gear 30 is driven to rotate by the first motor 29. The rotating second active bevel gear 30 drives the second driven bevel gear 31 and the first rotating shaft 6 to rotate through meshing transmission. The first rotating shaft 6 drives the top chuck 7 to rotate, thereby driving the cleaning brush 8 on the top to rotate along. The rotating cleaning brush 8 is used to carefully clean the outer surface of the part to remove dust and dirt on the surface, thereby improving the quality of subsequent painting.

[0025] Furthermore, the outer ends of the short shafts 12 are fixedly connected to the first driven bevel gears 14, and the second rotating shaft 15 is movably installed at the top of the base 1 near the lower position of the coating chamber 9. The second rotating shaft 15 is also made of high-quality metal material, and its end extends to the interior of the coating chamber 9 and is fixedly installed with the first active bevel gear 16. The top of the first active bevel gear 16 is meshed and connected with the bottom ends of all the first driven bevel gears 14. This meshing connection method can accurately transmit power and ensure that the short shaft 12 drives the cross brush plate 13 to rotate stably and at high speed.

[0026] Furthermore, an annular liquid infusion tube 17 is fixedly installed on the upper surface of the coating chamber 9. The annular liquid infusion tube 17 is made of a corrosion-resistant and well-sealed material. Four branch tubes 18 are fixedly connected to the bottom end thereof, and the ends of the branch tubes 18 extend to the interior of the corresponding side coating cavity 11. An inlet pipe 19 is fixedly installed on one side of the top end of the annular liquid infusion tube 17. The inlet pipe 19 can be connected to an external paint supply device to ensure that the paint can flow smoothly into the coating cavity 11.

[0027] Specifically, the lifting cylinder 33 controls the parts to descend into the coating tank 10, and introduces paint into the annular liquid infusion pipe 17 through the liquid inlet pipe 19. The paint will flow into each coating cavity 11 through the branch pipe 18. While the first rotating shaft 6 rotates, it will also drive the second rotating shaft 15 to rotate through the transmission of the synchronous wheel 27 and the synchronous belt 28. The second rotating shaft 15 drives the first active bevel gear 16 to rotate. The rotating first active bevel gear 16 drives all the first driven bevel gears 14 to rotate at high speed through meshing transmission. The rotating first driven bevel gear 14 drives all the cross brush plates 13 to rotate at high speed through the short shaft 12, and the paint introduced into the coating cavity 11 is scattered and mixed with air to form a gas flow. These paint gas flows are sprayed onto the outer surface of the parts at high speed to achieve surface coating of the parts, which not only improves the uniformity of paint coating, but also improves the coating quality.

[0028] Furthermore, a rotating ring 23 is movably installed on the upper surface of the workbench 3 near the outer side of the drying chamber 20, and permanent magnets 24 are fixedly installed on both sides of the top of the rotating ring 23. The permanent magnets 24 have a stable and strong magnetic field strength. A third rotating shaft 25 is movably installed on the top of the base 1 near the bottom of the drying chamber 20. Both sides of the top of the third rotating shaft 25 are fixedly connected with diagonal support frames 26, and the ends of the diagonal support frames 26 are respectively fixedly connected to both sides of the bottom end of the rotating ring 23. The diagonal support frames 26 can stably support the rotating ring 23 and transmit the power of the third rotating shaft 25.

[0029] Specifically, the parts are moved to the top of the drying chamber 20, and the lifting cylinder 33 is used to control the parts to descend into the drying tank 21. At the same time, the aluminum tube 41 will enter between the two permanent magnets 24, and the electric heater 22 will be started to heat and cure the parts. When the first rotating shaft 6 rotates, the third rotating shaft 25 will be driven to rotate by the transmission of the synchronous wheel 27 and the synchronous belt 28. The rotating third rotating shaft 25 drives the rotating ring 23 to rotate through the diagonal support frame 26 on the top. The rotating ring 23 will drive the permanent magnet 24 on the top to make a circular motion. When the permanent magnet 24 moves, it will drive the magnetic field to follow the movement, causing the magnetic flux of the aluminum tube 41 to change. At this time, the aluminum tube 41 will be affected by the Ampere force and follow the direction of the magnetic field movement to rotate, thereby driving the movable sleeve 43 and the clamped parts to follow the rotation, so that the parts are heated more evenly during heating and drying, thereby improving the drying quality.

[0030] Furthermore, synchronous wheels 27 are fixedly mounted on the middle outer diameters of the first rotating shaft 6, the second rotating shaft 15 and the third rotating shaft 25, and the outer diameters of the synchronous wheels 27 are connected by synchronous belts 28. The synchronous belts 28 have good transmission performance and durability. A first motor 29 is also fixedly mounted on one side of the top of the base 1. The first motor 29 adopts a high-performance motor, and a second driving bevel gear 30 is fixedly mounted on its driving end. A second driven bevel gear 31 is fixedly mounted on the lower outer diameter of the first rotating shaft 6, and the second driven bevel gear 31 is meshed and connected with the inner ends of the second driving bevel gear 30. A series of gears and rotating shafts are driven by the motor to achieve coordinated work of various components.

[0031] Furthermore, a lifting cylinder 33 is fixedly installed in the middle of the bottom end of the workbench 3. The lifting cylinder 33 has sufficient power and stroke. Its driving end extends to the interior of the cylinder 32 and is movably installed at the bottom end of the lifting rod 34. Both ends of the lifting rod 34 are fixedly connected with splines 35. Key grooves 36 are provided on both sides of the interior of the cylinder 32. The outer walls of the splines 35 are movably connected to the corresponding side key grooves 36. This structure can not only ensure the stable lifting and lowering of the lifting rod 34 in the cylinder 32, but also realize the transmission of rotational motion. A worm gear 37 is fixedly installed on the outer diameter of the lower side of the cylinder 32, and a second motor 38 is fixedly installed on one side of the top end of the workbench 3. A worm 39 is fixedly installed on the driving end of the second motor 38, and the worm 39 is meshed and connected with the inner end of the worm wheel 37. The rotational motion of the cylinder 32 and the lifting rod 34 is realized through the transmission of the worm and worm wheel.

[0032] Furthermore, an electric telescopic rod 42 is fixedly installed on the outer side of the top end of the cross frame 40, and the electric telescopic rod 42 can accurately control the telescopic length. An aluminum cylinder 41 is movably installed on the outer side of the bottom end of the cross frame 40, and a movable sleeve 43 is movably installed on the bottom of the aluminum cylinder 41. A plurality of first cross rods 44 are evenly and movably installed on the outer wall of the movable sleeve 43, and a plurality of second cross rods 45 are evenly and movably installed on the lower outer diameter of the aluminum cylinder 41. The ends of the first cross rods 44 and the second cross rods 45 on the corresponding sides are movably installed on both sides of the inner end of the support plate 46. The driving ends of the electric telescopic rods 42 pass through the interior of the aluminum cylinder 41 on the corresponding side and are movably installed in the middle of the movable sleeve 43. The movement of the cross rods is driven by the extension and retraction of the electric telescopic rod 42, so that the support plate 46 can clamp and release the parts.

[0033] Specifically, the electric telescopic rod 42 is started, and the internal piston rod is retracted through the electric telescopic rod 42, driving the movable sleeve 43 to rise. The rising movable sleeve 43 will drive one end of the first cross rod 44 to rise, and cooperate with the second cross rod 45 to form a stable scissor-type structure, driving all the support plates 46 to expand outward, thereby clamping the engineering parts from the inside to prevent the parts from falling off during later operations.

[0034] Working principle: First, the staff places the engineering parts to be coated with paint at the loading port 4, and then starts the lifting cylinder 33. The lifting cylinder 33 accurately controls the lifting rod 34 to descend, driving the cross frame 40 and the aluminum tube 41 at the end of the cross frame 40 to descend and enter the interior of the engineering parts. Then, the electric telescopic rod 42 is started, and the internal piston rod is retracted by the electric telescopic rod 42, driving the movable sleeve 43 to rise. The rising movable sleeve 43 will drive one end of the first cross rod 44 to rise, and cooperate with the second cross rod 45 to form a stable scissor-type structure, driving all the support plates 46 to expand outward, thereby clamping the engineering parts from the inside to prevent the parts from falling off during later operations. After completion, the lifting cylinder 33 controls the lifting rod 34 and the clamped parts to rise and reset. Then, the second motor 38 is started, and the worm 39 is driven to rotate by the second motor 38. The rotating worm 39 drives the worm wheel 37 and the cylinder 32 to rotate through meshing transmission. The spline 35 and the keyway 36 are used to limit the lifting rod 34 to rotate ninety degrees, so that the clamped parts move above the cleaning port 5. The lifting cylinder 33 is used to control the parts to fall below the cleaning port 5 again. Then, the first motor 29 is started, and the second active bevel gear 30 is driven to rotate by the first motor 29. The rotating second active bevel gear 30 drives the second driven bevel gear 31 and the first rotating shaft 6 to rotate through meshing transmission. The first rotating shaft 6 drives the top chuck 7 to rotate, thereby driving the cleaning brush 8 on the top to rotate with it, and the rotating cleaning brush 8 is used to clean the outer surface of the part. Careful cleaning is performed to remove dust and dirt on the surface, which can improve the quality of subsequent painting. After cleaning, the lifting cylinder 33 controls the parts to rise and reset again, and the second motor 38 drives the worm 39 to rotate again, and cooperates with the worm gear 37, the cylinder 32 and other structures to rotate the lifting rod 34 ninety degrees again, so that the parts are moved above the coating chamber 9, and the lifting cylinder 33 controls the parts to descend into the coating tank 10, and the paint is introduced into the annular infusion pipe 17 through the liquid inlet pipe 19. The paint will flow into each coating cavity 11 through the branch pipe 18, and the first rotating shaft 6 will drive the second rotating shaft 15 to rotate through the transmission of the synchronous wheel 27 and the synchronous belt 28 while the first rotating shaft 6 rotates, and the second rotating shaft 15 drives the first active bevel gear 16 to rotate, and the rotating first active bevel gear The gear 16 drives all the first driven bevel gears 14 to rotate at high speed through meshing transmission. The rotating first driven bevel gears 14 drive all the cross brush plates 13 to rotate at high speed through the short shaft 12, and the paint introduced into the coating chamber 11 is scattered and mixed with air to form a gas flow. These paint gas flows are sprayed onto the outer surface of the parts at high speed to achieve surface coating of the parts, which not only improves the uniformity of paint coating, but also improves the coating quality. After the coating is completed, the parts are raised and reset by the control of the lifting cylinder 33. The second motor 38 controls the lifting rod 34 to rotate ninety degrees again to move the parts to the top of the drying chamber 20. The lifting cylinder 33 is used to control the parts to descend into the drying tank 21. At the same time, the aluminum cylinder 41 will enter between the two permanent magnets 24.The electric heater 22 is started to heat and cure the parts. When the first rotating shaft 6 rotates, the third rotating shaft 25 is also driven to rotate by the transmission of the synchronous wheel 27 and the synchronous belt 28. The rotating third rotating shaft 25 drives the rotating ring 23 to rotate through the top diagonal support frame 26. The rotating ring 23 drives the permanent magnet 24 on the top to make a circular motion. When the permanent magnet 24 moves, it drives the magnetic field to follow the movement, causing the magnetic flux of the aluminum cylinder 41 to change. At this time, the aluminum cylinder 41 will be affected by the Ampere force and follow the direction of the magnetic field to rotate, thereby driving the movable sleeve 43 and the clamped parts to follow the rotation, so that the parts are heated more evenly during heating and drying, and the drying quality is improved. After the drying is completed, the parts are controlled to rise and reset again. After the lifting rod 34 rotates ninety degrees again, the parts return to the initial loading port 4 position, and the electric telescopic rod 42 is started again to tighten the support plate 46 inward to release the clamping effect on the parts. The staff can remove the parts and put in new workpieces. The multi-station design can shorten the coating cycle of a single part and improve production efficiency.
