[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application; that is, the described embodiments are only a part of the embodiments of this application, and not all of them. The components of the embodiments of this application described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides a working method for a surface treatment device for annular workpieces, specifically including:

[0030] The gantry crane places the annular workpiece to be processed onto a support fixture, the top of which is equipped with a limiting angle plate, such as... Figure 10 As shown, before the improvement, a concave limiting plate was used to contact the inner and outer walls of the workpiece; after the improvement, a limiting angle plate was used to contact only the outer wall of the workpiece, thus reducing the number of contact points.

[0031] like Figures 2-3 As shown, the overhead crane transports the annular workpiece and supporting fixture to the horizontal rotating spray fixture in the degreasing spray area. Degreasing agent is sprayed onto the inner and outer surfaces of the rotating annular workpiece for degreasing treatment. After degreasing, pure water is sprayed onto the inner and outer surfaces for degreasing rinsing. Specifically, the first degreasing tower first supplies degreasing agent to the degreasing spray pipe for spraying. The degreasing agent falling from the annular workpiece flows back to the second degreasing tower. After reaching the liquid level threshold, the second degreasing tower starts heating. When all the degreasing agent in the first degreasing tower has flowed back to the second degreasing tower, the second degreasing tower then supplies degreasing agent to the degreasing spray pipe for spraying. The degreasing agent falling from the annular workpiece flows back to the first degreasing tower. After reaching the liquid level threshold, the first degreasing tower starts heating. When all the degreasing agent in the second degreasing tower has flowed back to the first degreasing tower, the process is repeated.

[0032] As Figures 4-5 shown, the trolley transports the annular workpiece and the supporting tool into the horizontal rotating spray tool of the blackening spray area, sprays the rotating annular workpiece with the first blackening concentration liquid, sprays pure water to the inner and outer surfaces of the rotating annular workpiece for the first rinsing after the first blackening, sprays the rotating annular workpiece with the second blackening concentration liquid for the second blackening, sprays pure water to the inner and outer surfaces of the rotating annular workpiece for the second rinsing after the second blackening. Specifically, the three first blackening towers are the first blackening tower A, the first blackening tower B and the first blackening tower C. The first blackening tower A and the first blackening tower B have the first blackening concentration liquid. The first blackening tower A supplies the liquid to the first blackening spray pipe for spraying. The first blackening concentration liquid falling from the annular workpiece flows back to the first blackening tower C. When the liquid level threshold is reached, the first blackening tower C starts heating. When all the liquid in the first blackening tower A flows back to the first blackening tower C, the first blackening tower B supplies the liquid to the first blackening spray pipe for spraying. The first blackening concentration liquid falling from the annular workpiece flows back to the first blackening tower A. When the liquid level threshold is reached, the first blackening tower A starts heating. When all the liquid in the first blackening tower B flows back to the first blackening tower A, the first blackening tower C has reached the working temperature and supplies the liquid to the first blackening spray pipe for spraying. The first blackening concentration liquid falling from the annular workpiece flows back to the first blackening tower B. When the liquid level threshold is reached, the first blackening tower B starts heating. When all the liquid in the first blackening tower B flows back to the first blackening tower C, the above steps are repeated. The working modes of the three second blackening towers are the same as those of the three first blackening towers.

[0033] As Figure 6 shown, the trolley transports the annular workpiece and the supporting tool into the hot water tank to remove the residual blackening liquid and waste residue on the surface of the annular workpiece. At the same time, the annular workpiece is heated. The water on the surface of the annular workpiece is evaporated instantly when the annular workpiece is removed from the hot water tank.

[0034] As Figures 7-8 shown, the trolley transports the annular workpiece and the supporting tool into the horizontal rotating spray tool of the oil immersion spray area to spray the inner and outer surfaces of the rotating annular workpiece with the rust-proof oil.

[0035] The foregoing description of specific exemplary embodiments of the application has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the application to the precise form disclosed, and various modifications and variations are possible in light of the above teachings. It is intended that the application encompass all such modifications and variations as fall within the scope of the claims and their equivalents. It is intended that the scope of the application extend to all alternative combinations of the various features and embodiments described herein.
