[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1-2 The embodiments of this utility model include:

[0021] like Figure 1 and Figure 2 The step-type spray rust prevention treatment equipment shown is used for rust prevention treatment of shaft workpieces 6. The shaft workpieces 6 are provided with axially extending through holes. The equipment includes: frame 1, chain conveyor 2, rust prevention spray chamber 3, air-cutting oil return chamber 4 and oil mist processor 15. The rust prevention spray chamber 3 and the air-cutting oil return chamber 4 are arranged at intervals on the frame 1. First, the shaft workpieces 6 are sprayed with rust prevention oil inside and outside, and then the excess rust prevention oil is blown off for recycling.

[0022] A chain conveyor 2 is installed in the frame 1. The chain conveyor 2 is equipped with two parallel conveyor chains 16 that pass through the rust-proof spray chamber 3 and the air-cutting oil return chamber 4. A connecting rod 5 is installed between the two conveyor chains 16, and the connecting rod 5 is supported and conveyed by the two conveyor chains 16.

[0023] In this embodiment, the connecting rods 5 are evenly spaced along the length of the conveyor chain 16. A door panel 10 and a cylinder 12 for driving the door panel 10 to rise and fall are respectively installed at both ends of the rust-preventive spray chamber 3. After the connecting rods 5 enter the rust-preventive spray chamber 3, the cylinder 12 lowers the door panel 10, thus sealing both ends of the rust-preventive spray chamber 3 and reducing the escape of oil mist during spraying. Furthermore, a pipe 13 is installed between the oil mist processor 15 and the rust-preventive spray chamber 3 to draw the oil mist from the rust-preventive spray chamber 3 into the oil mist processor 15 for oil mist separation. After spraying is completed, the cylinder 12 drives the door panel 10 upwards, and the chain conveyor 2 drives the connecting rods 5 forward a distance equal to the distance between two adjacent connecting rods 5. Then, the cylinder 12 drives the door panel 10 downwards to continue spraying. Figure 1 As shown, each shaft-type workpiece 6 can undergo two spraying and air-cutting treatments to improve the processing effect.

[0024] A first V-block 21 and a second V-block 22 are axially spaced on the connecting rod 5, which can perform self-positioning at both ends of the shaft-like workpiece 6. The chain conveyor 2 is equipped with a motor 17 that drives the conveyor chain 16 to operate. The motor 17 can be intermittently rotated by a PLC to realize the gradual forward movement of the connecting rod 5 and the shaft-like workpiece 6 in the frame 1.

[0025] like Figure 2 As shown, in this embodiment, the height of the first V-block 21 is lower than the height of the second V-block 22. The two ends of the shaft workpiece 6 can be placed obliquely on the first V-block 21 and the second V-block 22. The oblique placement of the shaft workpiece 6 improves the fluidity of the anti-rust oil in its through hole, ensures the anti-rust treatment effect inside the through hole, and also facilitates the outflow of excess anti-rust oil, improving the recycling efficiency.

[0026] A first lifting platform 8 is provided on the rust-preventive spray chamber 3. A first lifting seat 9 is provided at the bottom of the first lifting platform 8 above the connecting rod. A first liquid delivery pipe 25 is provided at the end of the first lifting seat 9 corresponding to the first V-block 21, extending to the outside of two adjacent first V-blocks 21. A first nozzle 26 is provided on the first liquid delivery pipe 25 pointing to the first V-block 21. The height of the first nozzle 26 is adjusted by the first lifting seat 9 so that the first nozzle 26 can be aligned with the through hole at one end of the shaft workpiece 6, and the rust-preventive oil is sprayed into the through hole to perform rust prevention treatment on the inner wall of the through hole.

[0027] The first lifting seat 9 is provided with a second liquid delivery pipe 28 extending to the outside of the second V-shaped block 22 at one end corresponding to the second V-shaped block 22. The second liquid delivery pipe 28 is provided with a second nozzle 29 pointing to the second V-shaped block. The second nozzle 29 is aligned with the other end of the through hole in the shaft workpiece 6 and sprays the rust-preventive oil into the through hole to perform rust prevention treatment on the inner wall of the through hole, ensuring the treatment effect.

[0028] A spray pipe 7 is installed in the rust-preventive spray chamber 3, located above and below the connecting rod path. A third nozzle 27 is installed on the spray pipe 7, pointing towards the connecting rod. The rust-preventive oil is sprayed onto the outer wall of the shaft workpiece 6 through the third nozzle 27, thereby achieving rust prevention treatment of the outer wall. A spray pump 30 is installed outside the rust-preventive spray chamber 3. The outlet of the spray pump 30 is connected to the spray pipe 7, the first liquid delivery pipe 25, and the second liquid delivery pipe 28, respectively, to deliver the rust-preventive oil into the spray pipe 7, the first liquid delivery pipe 25, and the second liquid delivery pipe 28, thereby achieving synchronous internal and external spraying of the shaft workpiece 6.

[0029] A second lift 14 is provided on the air-cutting return oil chamber 4. A second lifting seat 19 located above the connecting rod path is provided at the bottom of the second lift 14. In this embodiment, the first lift 8 and the second lift 14 are screw lifts, which can be telescopically controlled by PLC, making them flexible to adjust and improving the adaptability to the center position height of the through hole of different outer diameter shaft parts.

[0030] A first air supply pipe extending to the outside of the path of the first V-shaped block 21 is provided at one end of the second lifting seat 19 corresponding to the first V-shaped block 21. A fourth nozzle pointing to the first V-shaped block 21 is provided on the first air supply pipe. A second air supply pipe 18 extending to the outside of the second V-shaped block 22 is provided at one end of the second lifting seat 19 corresponding to the second V-shaped block 22. A fifth nozzle 20 pointing to the second V-shaped block is provided on the second air supply pipe 18. Air is blown to both ends of the shaft workpiece 6 simultaneously through the fourth nozzle and the fifth nozzle 20 to accelerate the outflow of excess rust-preventive oil in the through hole.

[0031] like Figure 1As shown, the air-cutting return oil chamber 4 is equipped with air knives 11 located above and below the connecting rod path to blow air onto the outer wall of the shaft workpiece 6 and remove excess anti-rust oil. In this embodiment, a fan 24 is provided on the outside of the air-cutting return oil chamber 4. The air outlet of the fan 24 is connected to the first air supply pipe, the second air supply pipe 18, and the air knife 11, respectively, and simultaneously delivers airflow to the first air supply pipe, the second air supply pipe 18, and the air knife 11.

[0032] In this embodiment, the frame 1 is provided with an oil return trough 23 located below the rust-preventive spray chamber 3 and the air-cutting oil return chamber 4. Excess rust-preventive oil in the rust-preventive spray chamber 3 and the air-cutting oil return chamber 4 falls into the oil return trough 23 and is supplied to the spray pump 30 for secondary use, thereby reducing costs.

[0033] In summary, the step-type spray rust prevention treatment equipment disclosed in this utility model can continuously spray rust-preventive oil and air cut the shaft workpiece twice, thereby improving the rust prevention effect and ensuring the recovery of excess rust-preventive oil inside and outside the shaft workpiece.

[0034] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
