Description

Technical Field

[0001] The utility model belongs to the field of aircraft engine propeller cap painting, and relates to a rotary device for aircraft engine propeller cap painting. Background Art

[0002] At present, the propeller cap is placed on a fixed tooling during painting. Particles often appear at the bottom of the propeller cap during painting, and it cannot rotate during spraying, so people need to move it for spraying. Secondly, since the existing propeller cap tooling is fixed, it cannot be transferred to the drying room for drying after painting, and room temperature is used for drying. Due to the long natural drying time, the production cycle is affected. Content of the Utility Model

[0004] The utility model is used to solve the problem of difficult painting of aircraft engine propeller caps. By using the utility model, the purpose of facilitating the operation and transportation of painters, strengthening the protection of propeller cap components, and improving the quality of the paint layer is achieved.

[0005] Technical Solution

[0006] The utility model is designed according to the special structure of the aircraft engine propeller cap.

[0007] A rotary device for aircraft engine propeller cap painting includes four parts: a fixed retaining ring 1, a bottom plate 2, a fixed handle 3, and a universal wheel 6; the fixed retaining ring 1 is welded to the center position of the bottom plate 2 through a support leg, the fixed handle 3 is circular and welded to the outer edge of the bottom plate 2, and an opening is provided at the center position of the bottom plate 2 to prevent paint mist from accumulating at the bottom of the part during painting.

[0008] Furthermore, it further includes a detachable handle 4, and the detachable handle 4 is screwed on the side wall of the bottom plate 2 and is used to pull the rotary device when transporting the propeller cap.

[0009] Furthermore, it further includes a universal wheel 6, and the universal wheel 6 is arranged at the bottom of the bottom plate 2 and is used for steering during transportation.

[0010] Furthermore, the number of the universal wheels 6 is three, and they are evenly distributed at the bottom of the bottom plate 2.

[0011] Furthermore, a canvas is wound around the fixed retaining ring 1 to play a buffering and protecting role.

[0012] Furthermore, a rubber pad is provided on the upper surface of the bottom plate 2 to play a role in buffering and protecting the propeller cap.

[0013] Furthermore, a retaining wall is provided on the circumference of the bottom plate 2, and the height of the retaining wall is 25 mm to prevent the propeller cap from tipping over.

[0014] The beneficial effects of this application are as follows:

[0015] Compared with ordinary part transfer / placement tooling, the structure and shape of the present utility model are designed according to the particularity of the aircraft engine propeller cap component. The diameter of the bottom plate is slightly larger than the bottom diameter of the propeller cap. The perimeter around the bottom plate can play a role in protecting and fixing from the outside. The fixed retaining ring on the bottom plate can prevent the propeller cap component from tipping over from the inside, and can meet the stable placement and transfer of the aircraft engine propeller cap component. Coupled with the detachable handle and the fixed handle, it provides convenience for the painting operator; the bottom plate is at a certain height from the ground, and the opening design in the middle of the bottom plate can reduce the paint mist flocculation and paint layer pollution problems at the bottom of the propeller cap during painting operations, thereby effectively improving and enhancing the surface paint layer quality of the aircraft engine propeller cap.
