After the second motor 8 is started, the second motor 8 can drive the rotating frame 9 to rotate. The centrifugal casting pipe is clamped and fixed on the rotating frame 9. The rotating frame 9 can drive the centrifugal casting pipe to rotate, so that the centrifugal casting pipe can be sprayed from all directions.
[0042] As a preferred embodiment of this utility model, the clamping mechanism includes: a clamp 10, a handle 11, a positioning frame 12, a spring 13, a fixing block 14, and a rotating rod 15;
[0043] The clamp 10 is slidably connected to the rotating frame 9. The handle 11 is fixedly connected to the clamp 10. The positioning frame 12 is slidably connected to the handle 11. The positioning frame 12 is fixedly connected to the spring 13. The spring 13 is fixedly connected to the fixing block 14. The fixing block 14 is fixedly connected to the handle 11. The rotating rod 15 is rotatably connected to the handle 11. The handle 11 cooperates with the positioning frame 12.

The fixed position of the centrifugal casting pipe can also be selected.
[0044] As a preferred embodiment of this utility model, the top and bottom of the rear side of the rotating frame 9 are provided with multiple positioning slots arranged at equal intervals.

Place the centrifugal cast pipe on the left side of the rotating frame 9, then hold the handle 11 and push the rotating rod 15 to rotate. Pushing will pry the positioning frame 12 away from the rotating frame 9, thus unlocking the clamp 10 at the current position. The position of the clamp 10 can then be freely adjusted on the rotating frame 9 to accommodate centrifugal cast pipes of various diameters. The fixing position of the centrifugal cast pipe can also be selected by placing the centrifugal cast pipe between the two clamps 10 or on the outside of the two clamps 10. Clamping the outside of the centrifugal cast pipe will not affect the internal spraying, and opening and fixing the inside of the centrifugal cast pipe will not affect the external spraying. Spraying can be performed on either the outside or the inside of the centrifugal cast pipe. After fixing, release the positioning frame 12, allowing it to automatically engage with the bracket 7. Multiple positioning slots are evenly spaced at both the top and bottom. Positioning blocks are fixedly installed on the positioning frame 12.

When spraying the centrifugal casting pipe, the first electric push rod 2, the second electric push rod 4, the first motor 5, the spray gun 6, and the second motor 8 are started to spray the centrifugal casting pipe. The first electric push rod 2 can raise or lower the vertical position of the spray gun 6, and the second electric push rod 4 can push the first motor 5 and the spray gun 6 to move horizontally. Starting the motors again can adjust the angle of the spray gun 6 to facilitate spraying the centrifugal casting pipe.
