[0002] A patent application (CN202221415424.0) entitled "Surface Coating Device for Corrosion Protection of Pipe Fittings" is disclosed in the existing Chinese patent database. This device includes a main body with a coating nozzle mounted on it. A material receiving groove is located at the lower end of the main body, and a protective cover is connected to the upper end of the groove. The protective cover has loading and unloading holes at its upper end. A rotating shaft passes through the protective cover, and a roller is fitted onto the shaft. Partitions are evenly connected to the sides of the roller, and fixed seats are evenly spaced between the partitions. Each fixed seat is connected to a limiting post, and support blocks are symmetrically engaged on the sides of the limiting posts. A dust collection box and a drying box with identical shapes and structures are symmetrically arranged on both sides inside the protective cover. This surface coating device for corrosion protection of pipe fittings can perform dust removal, spraying, and drying treatments on pipe fittings. The dust removal, spraying, and drying areas are all protected by the protective cover, effectively improving spraying efficiency.

[0003] In the prior art, alloy pipes or columns will rust and corrode after being left for a long time after production, requiring rust prevention treatment. However, manual brushing by workers is inefficient and the bottom of the pipe is difficult to cover. Therefore, this paper aims to propose a surface coating rust prevention device for silicon-aluminum alloy structural parts, which can automate the brushing process, achieve higher coating uniformity, and eliminate coating dead corners.

In order to improve its shortcomings, this utility model provides a surface coating rust prevention device for silicon-aluminum alloy structural parts.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0016] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3The diagram shows a surface coating anti-rust device for silicon-aluminum alloy structural parts, comprising a frame 1, a supporting rotating component within the frame 1, a base 2, a cavity 3 within the base 2, a horizontal bidirectional lead screw 4 within the cavity 3, a drive motor 5 on the outer side of the base 2, one end of the bidirectional lead screw 4 being shaft-connected to the output end of the drive motor 5, and first lead screw nut seats 6 fitted onto both the positive and negative threads of the bidirectional lead screw 4, with a rotating wheel assembly 7 connected to the upper end of each first lead screw nut seat 6, each rotating wheel assembly 7 being driven by a first reducer 8, forming an active rotating wheel system. Driven rotating wheel systems are spaced apart along the longitudinal direction of the frame 1, with the driven rotating wheel systems having the same structure as the active rotating wheel systems, and a column 9 placed between the rotating wheel assemblies 7 of the driven and active rotating wheel systems. A coating assembly 10 is vertically connected to the frame 1 above the column 9. The frame 1 includes four columns 101, with the upper parts of two horizontally arranged columns 101 connected by a crossbeam 102. The coating assembly 10 includes a connecting plate 11. A cylinder 12 is fixedly mounted on the upper surface of the connecting plate 11. An adhesive plate 13 is connected to the free end of the piston rod of the cylinder 12. A vertical guide post 14 is integrally mounted on the upper surface of the adhesive plate 13. A guide sleeve 15 is integrally mounted on the upper surface of the connecting plate 11. The guide post 14 is vertically and movably inserted into the guide sleeve 15. An oil brush body 16 is bonded to the lower surface of the adhesive plate 13. A horizontal moving mechanism is provided on the frame 1 located directly above the coating assembly 10. The horizontal moving mechanism is fixedly mounted to the connecting plate 11. The horizontal moving mechanism includes a ball screw 17 connected between the crossbeams 102, a second screw nut seat 18 connected to the ball screw 17, the length direction of the ball screw 17 being consistent with the length direction of the column 9, a second reducer 19 mounted on the outer side of the crossbeam 102, the output end of the second reducer 19 being axially connected to one end of the ball screw 17, and the lower surface of the second screw nut seat 18 being bolted to the connecting plate 11 in the coating assembly 10. The wheel assembly 7 includes a wheel seat 20 fixed to the upper surface of the first screw nut seat 6 and a wheel body 21 rotatably connected to the wheel seat 20, a hollow shaft 22 inserted inside the wheel seat 20, and a keyway in the axial direction opened on the inner surface of the hollow shaft 22, the output shaft of the first reducer 8 being inserted into the hollow shaft 22 and engaged with the hollow shaft 22 by a flat key 23.

[0018] The operation of this utility model consists of the following steps:

[0019] 1. Adjusting the distance between the two wheel assemblies 7 in the active wheel system and the driven wheel system: The operator drives the motor 5 to work, and the motor 5 drives the bidirectional lead screw 4 to rotate. According to the diameter of the alloy pipe or column 9 to be coated, the two first lead screw nut seats 6 on the bidirectional lead screw 4 move horizontally towards or away from each other to adjust the appropriate distance.

[0020] 2. Placement of alloy pipe fittings or column fittings 9: The operator places the alloy pipe fittings or column fittings 9 between the active and driven wheel systems and the wheel assembly 7 using external clamps or lifting devices, so that the outer surface of the alloy pipe fittings or column fittings 9 overlaps with the outer surface of the wheel body 21 in the wheel assembly 7.

[0021] 3. The position adjustment of the coating component 10 is achieved by controlling the extension and retraction of the piston rod of the cylinder 12, so that the lower surface of the brush body 16 is in contact with the upper end of the alloy pipe or column 9 after placement. Here, the cylinder 12 is selected with solenoid valve control, which can stop at any extension length position, thereby adapting to pipes or columns 9 of different diameters.

[0022] 4. The painting process: The two reducers of the active rotary wheel system start synchronously, causing the rotary wheel body 21 in the rotary wheel assembly 7 to rotate, which drives the alloy pipe or column 9 to rotate. The oil brush body 16 applies the anti-rust medium to the surface of the alloy pipe or column 9 under the action of rotation. Since the length of the oil brush body 16 is much smaller than the length of the alloy pipe or column 9, the oil brush body 16 is moved along the length direction of the alloy pipe or column 9 through the horizontal moving mechanism, thereby adjusting the working coverage of the oil brush body 16 and completing the overall surface painting of the alloy pipe or column 9. The working process of the horizontal moving mechanism is that the second reducer 19 drives the ball screw 17 to rotate. The ball screw 17 drives the second screw nut seat 18 to move along the length direction of the ball screw 17 through rotation, thereby driving the painting assembly 10, which is fixed to the bottom of the second screw nut seat 18, to move horizontally along the length direction of the alloy pipe or column 9 to complete the painting work.

[0023] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
