[0028] Reference Figure 1 and Figure 2As shown, a brake drum spraying device 1000 of an embodiment of the utility model comprises: a frame 100, a rotating disk 200, a driving assembly 300, a nozzle 400 and a bracket 410. The frame 100 is provided with a workbench 110, and the rotating disk 200 is arranged on the upper end surface of the workbench 110. The driving assembly 300 is used to drive the rotating disk 200 to rotate, and the rotating disk 200 is provided with a processing position, which can be used to process different workpieces, such as bearings, protective covers, etc. In order to more clearly describe this brake drum spraying device 1000, the workpiece is a brake drum 600 as an example for explanation.

[0029] The driving assembly 300 is connected to the frame 100, and its purpose is to drive the rotating disk 200 to rotate, thereby driving the brake drum 600 to rotate. One end of the bracket 410 is connected to the frame 100, and the other end is connected to the nozzle 400, and the nozzle 400 is connected to the nozzle head, which protrudes above the rotating disk 200. When the brake drum 600 is installed in the processing position, the nozzle head is located inside the brake drum 600, so as to spray the inner wall and flange surface of the brake drum 600.

[0030] The operation of the driving assembly 300 drives the rotating disk 200 to rotate, thereby driving the rotation of the brake drum 600. The spray head is arranged above the rotating disk 200, and the brake drum 600 is at the processing position. As the rotating disk 200 rotates, the spray head releases the paint, so that the inner wall of the brake drum 600 can be automatically and evenly sprayed with paint, anti-rust oil and other coatings through uniform rotation. This design does not require manual intervention in the spraying process, effectively reduces potential harm to the human body, improves work efficiency, and also reduces labor costs.

[0031] The bracket 410 can be connected to the upper end surface of the workbench 110, or to the lower end surface of the workbench 110. When one end of the nozzle 400 connected to the bracket 410 is located above the other end thereof, the nozzle head is located inside the brake drum 600, and the spraying liquid is sprayed from top to bottom. At this time, in order to avoid obstacles caused by the bracket 410, the nozzle 400 and the nozzle head during the upper and lower loading process, an adjustment device can be provided to make the bracket 410 have a telescopic function. The adjustment device can adopt an adjustment screw or a locking device. Placing the nozzle 400, the bracket 410 and the nozzle head above the rotating disk 200 will require additional operations to ensure smooth loading and unloading. Therefore, in order to simplify the operation, the bracket 410 is placed below the workbench 110 to ensure that the end of the bracket 410 connected to the nozzle 400 is located below the workbench 110. The nozzle 400 passes through the rotating disk 200, and the nozzle head protrudes from the upper end surface of the rotating disk 200 to spray the inner wall of the brake drum 600. This layout makes it possible for the bracket 410 and the nozzle 400 to not hinder loading and unloading, and the brake drum 600 can be conveniently placed and removed without additional operations. This design is intended to increase processing speed and reduce labor costs.

[0032] In some embodiments of the utility model, the nozzle 400 is connected with a plurality of nozzles, which can be connected at the same position of the nozzle 400 or at different positions of the nozzle 400. On the one hand, it can ensure that the paint is evenly distributed on the covered surface. This is very important for ensuring the quality and appearance of the coating. On the other hand, it can improve the spraying efficiency. Arranging multiple nozzles at different positions can reduce the mutual interference of the sprayed paint. After the paint or liquid is sprayed in the air, it may collide with each other, resulting in uneven coating. By reasonably designing the positions of the multiple nozzles, the collision between the spray liquids can be reduced or minimized, and the uniformity of coverage can be improved. By adjusting the positions and directions of the multiple nozzles, it can be ensured that the paint completely covers the inner wall of the brake drum 600, thereby improving the product quality.

[0033] refer to Figure 1 As shown, in some embodiments of the utility model, the brake drum spraying equipment 1000 includes a plurality of limit posts 420, which are spaced apart on the edge of the rotating disk 200 and are used to limit the brake drum 600 at the processing position to prevent the brake drum 600 from being thrown out of the rotating disk 200 under the action of centrifugal force during rotation, thereby reducing the displacement of the position of the brake drum 600.

[0034] The limiting column 420 can be connected to the rotating disk 200 in a fixed connection or a detachable connection. When the limiting column 420 is detachably connected to the rotating disk 200, the limiting column 420 of different radius can be replaced to adapt to brake drums 600 or other workpieces of different sizes and provide stable limiting. The operation of disassembling and replacing the limiting columns 420 of different sizes is simple, which enhances the versatility of the brake drum spraying equipment 1000.

[0035] refer to Figure 1 As shown, in some embodiments of the utility model, the rotating disk 200 is provided with a limiting groove 210, which can be set in a concentric ring shape to match the edge of the brake drum 600, so that the center of the brake drum 600 is aligned with the center of the rotating disk, and the rotating disk 200 rotates stably to prevent the brake drum 600 from shaking abnormally during automatic rotation spraying. The limiting groove 210 can be matched with a limiting column 420, which can provide positioning support for the periphery of the brake drum 600, making the positioning more secure and further reducing the displacement of the brake drum 600.

[0036] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the brake drum spraying device 1000 further includes an oil collecting pan 500, which is connected to the frame 100 and disposed below the hollow shaft 310, and is intended to collect the paint dripping through the hollow shaft 310. This design not only helps to protect the environment, but also has economic benefits, because the excess paint can be recycled and reused.

[0037] refer to Figure 1 As shown, in some embodiments of the utility model, the rotating disk 200 is provided with multiple nozzles 400 and spray heads, that is, the brake drum spraying equipment 1000 is provided with multiple processing positions, and multiple spray heads can spray the brake drum 600 on multiple processing positions at the same time, which not only improves the spraying efficiency, but also reduces the steps of tooling.

[0038] refer to Figure 3 As shown, in some embodiments of the present invention, the bracket 410 includes a first connecting plate 411 and a second connecting plate 412, one end of the first connecting plate 411 is connected to the frame 100, and the second connecting plate 412 is connected to the nozzle 400. The first connecting plate 411 and the second connecting plate 412 are connected in a slidable manner so as to adjust the height of the nozzle 400 connected to the second connecting plate 412. The sliding connection can be selected as a buckle or a slide groove connection.

[0039] Since the brake drum 600 may have errors during the processing, thus affecting its height consistency, the position and height of the nozzle need to be adjusted to ensure that the paint can evenly and completely cover the inner wall surface of the brake drum 600. The adjustment allows the second connecting plate 412 to slide relative to the first connecting plate 411 in the vertical direction, thereby driving the nozzle 400 and its nozzle to move in the vertical direction, and adjusting the height of the nozzle to enhance the inclusiveness and applicability of the brake drum spraying equipment 1000.

[0040] refer to Figure 4 As shown, in some embodiments of the utility model, the driving assembly 300 includes a hollow shaft 310, a first gear 320, a second gear 330, a motor 340 and a roller chain 350, the first gear 320 is connected to the motor 340, the second gear 330 is connected to the hollow shaft 310 to connect to the rotating disk 200, and the first gear 320 and the second gear 330 are connected by the roller chain 350. Through the above structure, the motor 340 generates a rotational motion to drive the first gear 320 to rotate, thereby driving the rotating disk 200 to move through the roller chain 350, the second gear 330 and the hollow shaft 310. The middle part of the hollow shaft 310 is hollowed out, and the nozzle 400 passes through the hollow shaft 310, and one end of the nozzle is connected to the nozzle and is located above the rotating disk 200 to spray the inside of the brake drum 600.

[0041] During the spraying process, the paint that fails to adhere to the inner wall of the brake drum 600 drips and accumulates on the upper end surface of the rotating disk 200, affecting the rotation of the rotating disk 200 and possibly causing the liquid on the rotating disk to splash on the inner surface of the brake drum 600. Therefore, a hollow rotating shaft 310 is provided so that the liquid passes through the hollow rotating shaft 310 and flows out of the rotating disk 200. The second gear 330 is sleeved on the outer periphery of the hollow rotating shaft 310, and the rotational kinetic energy is provided by the roller chain 350, the first gear 320 and the motor 340. Through this simple structure, the excess paint can be effectively removed to ensure the spraying quality.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
