[0006] When doing a spray test, the fixed plate of the test bench is used to fix the test plate to be sprayed to prevent the test plate to be sprayed from being moved around by the paint spray gun. The drive shaft drives the turntable to rotate, and the turntable brings the test plate to the designated position under the paint spray gun. The rotating part then drives the test plate to rotate, which is convenient for spraying tests. When it is necessary to clean the inside of the shell, the spray assembly is used to spray cleaning water through the water spray head. The water spray head is designed with an adjustable angle to facilitate flushing and cleaning the inside of the shell. The scraper is connected with a lifting mechanism to facilitate the scraper to stick to or separate from the fixed plate. It sticks to the fixed plate when it needs to be cleaned, and separates from the fixed plate when it is not needed.
[0007] As a preferred embodiment of the present invention, the rotating member is a composite gear comprising a first ring gear and a second ring gear. A gear transmission is provided between the second ring gear and the fixed plate. A first motor is provided outside the housing, and a gear transmission is also provided between the first motor and the first ring gear. The first motor drives the first ring gear to rotate via the gear transmission, which in turn rotates the second ring gear. The second ring gear then drives the fixed plate to rotate via the gear transmission. Together with the paint spray gun, this allows the fixed plate to rotate while simultaneously spraying.
[0008] As a preferred embodiment of the present invention, the lifting mechanism comprises a base tube, within which is a telescopic tube, which in turn houses a second motor. The second motor is detachably connected to the scraper. When needed, the telescopic tube automatically extends from the base tube, separating the scraper from the fixed plate.

When cleaning the housing and the paint spray gun, the valves corresponding to the first and third pipes are opened, and the valve of the second pipe is closed. Clean water is used to clean the housing and the paint spray gun. Alternatively, the valve of the first pipe alone can be opened to clean stains inside the housing.
[0011] As a preferred solution of the present invention, the transmission shaft and the composite gear are coaxially designed, which makes the turntable compact and highly stable, and the transmission shaft allows the composite gear to rotate relative to each other, so that the turntable or the fixed plate can rotate independently.
[0012] As a preferred solution of the present invention, the fixed plate is circular, and the length of the scraper is greater than the diameter of the fixed plate, which is conducive to the scraper's all-round rotational cleaning of the fixed plate.
[0013] As a preferred solution of the present invention, the fixing plate is provided with a plurality of clamping claws, which facilitate the fixing plate to clamp the test plate to be sprayed.
[0014] As a preferred solution of the present invention, a water baffle is provided on the outer ring edge of the turntable to prevent clean water or paint from splashing onto or adhering to the transmission components.
[0015] As a preferred solution of the present invention, an anti-fouling partition is provided in the housing to prevent clean water or paint from splashing onto or adhering to the pipes and valves.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

The water spray head is designed with an adjustable angle to facilitate flushing and cleaning the inside of the shell. The scraper is connected with a lifting mechanism to facilitate the scraper to stick to or separate from the fixed plate. When the fixed plate needs to be cleaned, it is pressed against the fixed plate, and when it is not needed, it is separated from the fixed plate.
[0018] 2. The first motor drives the first gear ring to rotate through gear transmission, and the second gear ring also rotates. The second gear ring then drives the fixed plate to rotate through gear transmission, and works together with the paint spray gun to achieve the fixed plate rotating while spraying.
