Embodiment 1:

[0019] like Figure 1-4As shown, this embodiment discloses a surface spraying device for processing the front and rear wheel covers of a vehicle body, including a work box 1, a bracket 2 is arranged in the work box 1, the bracket 2 includes beams 3 at both ends and a slide rail 4 connecting the beams 3, and a movable block 5 is arranged on the slide rail 4. The movable block 5 is moved on the slide rail 4 by a first motor, and the first motor is arranged on the movable block 5 (not shown in the figure). The coordination between the motor and the slide rail 4 is the same as that of a general electric slide rail, and this embodiment and subsequent embodiments will not be repeated. The first motor and other equipment that needs power supply in this embodiment are all powered by an external power supply, and the power supply method is conventional power supply, and this embodiment will not be repeated. Figure 2 As shown, an electric control telescopic rod 6 is provided below the movable block 5, and a spraying frame 7 is provided at the bottom of the electric control telescopic rod 6. The spraying frame 7 includes an arc-shaped rack 71 and an arc-shaped rod 72 fixed below the arc-shaped rack 71. The spraying box 8 is movably connected to the spraying frame 7. Figure 3 As shown, a gear 82 and an arc buckle 83 are provided on the back of the spray box 8, the arc buckle 83 is engaged with the arc rod 72, the gear 82 is matched with the arc rack 71, and an electric control element for controlling the electric telescopic rod 6 and a second motor connected to the gear 82 are provided in the spray box 8. When the second motor drives the gear 82 to rotate, the spray box 8 moves in an arc along the spray frame under the limiting action of the arc buckle 83 and the arc rod 72. A nozzle 81 is provided at the bottom of the spray box 8, and the nozzle 81 is connected to the paint box through a paint pipe, and the spraying work is performed through a paint pump. Example

[0020] A leak plate 11 is provided in the working box 1, and a receiving chamber for receiving more than the spraying liquid is provided below the leak plate 11. A plurality of wheel cover support units 12 are provided on the leak plate 11. Figure 4 As shown, the support unit 12 is divided into two types, one is a convex piece 121 with an upper convex shape on the top, and the other is a concave piece 122 with a concave shape on the top. The upper convex piece 121 and the concave piece 122 are staggered on the leak plate 11. All the upper convex pieces 121 are connected to the leak plate 11 through the first telescopic rod group; all the concave pieces 122 are connected to the leak plate 11 through the second telescopic rod group; the first telescopic rod group and the second telescopic rod group are controlled to rise and fall by the controller. The support unit 12 will only support the wheel cover in one placement mode at the same time, so at the same time, only one and only one group of telescopic rod groups rises and the other group falls. The upper convex piece 121 and the concave piece 122 are both made of high friction coefficient materials. In this embodiment, rubber with a texture on the surface is used to increase the friction between the wheel cover. When the first telescopic rod group is raised, the upper convex part 121 that is closer to the center is raised higher, so that the tops of all the convex parts 121 are in an upward convex structure; when the second telescopic rod group is raised, the lower the concave part 122 that is closer to the center is raised lower, and the tops of all the concave parts 122 are in a concave structure together. Since the tops of the concave parts 122 are in the shape of suction cups, they can be further fixed when supporting the wheel cover placed in reverse.

[0021] The first telescopic rod group and the second telescopic rod group are controlled by a controller. All telescopic rods are fixed in a receiving box at the bottom of the leak plate and pass through the leak plate 11 to be connected to the support unit 12 .
