[0028] First, fix the bumper to be painted on the top of the support column 401 through the fixing assembly, and then start the paint spraying assembly to paint the surface of the bumper. At the same time, start the motor 4 to drive the support column 401 and the driving gear 7 to rotate. The driving gear 7 will drive the rotating seat 3 with the gear ring 302 to rotate in the opposite direction relative to the support column 401 at the top of the support sleeve 2 through a number of planetary 601 teeth. Therefore, the bumper on the support column 401 will be relatively reversed with the paint spraying assembly on the rotating seat 3, which is convenient for fast and uniform paint spraying on all sides of the bumper, thereby saving time and improving the painting effect. In addition, the fixed assembly set can also stably clamp and fix bumpers of different shapes and specifications to prevent the bumper from shaking during rotation and affecting the painting effect.

[0029] The bottom of the rotating seat 3 is provided with a rotating groove 303 matched with the supporting sleeve 2 ; the rotating seat 3 can stably rotate on the top of the supporting sleeve 2 through the provided rotating groove 303 .

The screws 8 will drive the fixing heads 9 to move so that the two fixing heads 9 are against the two sides of the bumper, so that the bumper can be stably fixed to prevent the bumper from shaking during the rotation process and affecting the painting effect.

[0035] Among them, the fixing head 9 includes an arc-shaped clamp 1 901, an arc-shaped clamp 2 902 rotatably set on the side wall of the arc-shaped clamp 1 901, and an arc-shaped clamp 3 903 rotatably set on the side wall of the arc-shaped clamp 2 902; when the fixing head 9 is close to the side wall of the bumper, if the shapes of the two sides of the bumper are irregular, the arc-shaped clamp 3 903 will rotate when contacting the side wall of the bumper, and the arc-shaped clamp 2 902 will also move inside the arc-shaped clamp 1 901, so that it can stably contact the side walls of bumpers of different shapes and specifications, which is convenient for clamping and fixing different bumpers, thereby improving the adaptability of the equipment.

[0036] In addition, a limit groove 1 is provided on the inner wall of the arc-shaped clamp 1 901, a limit block 1 matching with the limit groove 1 is provided on the outer wall of the arc-shaped clamp 2 902, a limit groove 2 is provided on the inner wall of the arc-shaped clamp 2 902, and a limit block 2 matching with the limit groove 2 is provided on the outer wall of the arc-shaped clamp 3 903; it can not only prevent the arc-shaped clamp 2 902 from detaching from the arc-shaped clamp 1 901 during rotation, but also prevent the arc-shaped clamp 3 903 from detaching from the arc-shaped clamp 2 902 during rotation, thereby improving the stability of the fixed head 9.

[0037] The working principle of the utility model is as follows: the bumper is placed in the placement frame 5, and then the screws 8 on both sides of the placement frame 5 are rotated, the screws 8 will drive the fixing heads 9 to move, so that the two fixing heads 9 are against the two sides of the bumper, so that the bumper can be stably fixed to prevent the bumper from shaking during the rotation process and affecting the painting effect; and when the fixing heads 9 are close to the side walls of the bumper, if the shapes of the two sides of the bumper are irregular, the arc-shaped clamping head three 903 will rotate when contacting with the side walls of the bumper, and the arc-shaped clamping head two 902 will also move inside the arc-shaped clamping head one 901, so that it can be compatible with the bumper side walls of different shapes and specifications. The wall is stably in contact, which is convenient for clamping and fixing different bumpers, thereby improving the adaptability of the equipment; then the paint spraying assembly is started to spray paint on the surface of the bumper. At the same time, the starting motor 4 drives the support column 401 and the driving gear 7 to rotate. The driving gear 7 will drive the rotating seat 3 with the gear ring 302 to rotate in the opposite direction relative to the support column 401 at the top of the support sleeve 2 through a number of planetary 601 teeth. Therefore, the bumper on the support column 401 will be relatively reversed with the paint spraying assembly on the rotating seat 3, which is convenient for quickly and evenly spraying paint on all sides of the bumper, thereby saving time and improving the painting effect.
