Description

Technical Field

[0001] This utility model relates to the field of fan housing processing, and in particular to a grinding device for fan housing processing. Background Technology

[0002] Fan housing manufacturing refers to a series of manufacturing processes applied to the fan housing. Typically, the process begins with cutting raw materials, usually plastic or metal, according to design drawings. Then, the basic shape of the housing is formed through processes such as injection molding or stamping. Injection molding is suitable for plastic housings, while stamping is used for metal housings. Next, surface treatments such as grinding, polishing, and spraying are performed to improve the housing's appearance and corrosion resistance. Drilling and tapping are also performed to facilitate the installation of other components. Finally, quality inspection is conducted to ensure that the housing's dimensional accuracy, appearance, and performance meet requirements, thus providing a qualified housing component for fan assembly.

[0003] However, current fan housing grinding devices typically only rotate the fan housing or grinding disc, resulting in low grinding efficiency. Furthermore, current fan housing grinding devices usually require workers to clean up the grinding debris, leading to high workload for workers. If workers do not clean up in time, it may affect subsequent grinding.

[0004] In response to this technical problem, this application proposes a grinding device for processing fan housings. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding device for processing fan housings. This device aims to rotate the fan housing and the grinding disc to improve the grinding efficiency of the fan housing, and to collect the debris generated during grinding in a timely manner, reducing the intensity of manual collection and minimizing the impact on subsequent grinding.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A polishing device for processing fan housings includes a dust collection box, a base fixedly connected to the top side of the dust collection box, a rotating ring rotatably connected to the top side of the base, a robotic arm fixedly connected to the outer wall of the rotating ring, a polishing disc for polishing work fixedly connected to the top end of the robotic arm, a turntable rotatably connected to the top side of the rotating ring, a fan housing connected to the middle of the turntable via a fixing component, a driving component for driving the rotating ring and the turntable to rotate in opposite directions on the top side of the base, and a collecting component for collecting debris generated during polishing on the outer wall of the base.

[0008] Furthermore, the fixing assembly includes a plug rod fixedly connected to the center of the turntable, and four limiting rods are fixedly connected to the outer wall of the plug rod. The top ends of the plug rod and the limiting rods are all inserted into the center of the fan housing.

[0009] Furthermore, the drive assembly includes a first gear rotatably connected to the top side of the base, a telescopic rod fixedly connected to the bottom end of the outer wall of the first gear, and one end of the telescopic rod fixedly connected to the inner wall of the rotating ring.

[0010] Furthermore, a second gear is fixedly connected to the center of the bottom side of the turntable, and the bottom end of the limiting rod is fixedly connected to the inside of the second gear, with the second gear and the first gear meshing with each other.

[0011] Furthermore, a motor is installed inside the base, and the drive end of the motor is fixedly connected to the bottom side of the first gear.

[0012] Furthermore, the collection assembly includes a dust collection groove formed on the bottom side of the outer wall of the base, and the dust collection groove has multiple dust discharge holes inside.

[0013] Furthermore, a dust collection box is provided inside the dust collection box, and a handle for pulling the dust collection box is fixedly connected to the right side of the dust collection box.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the first gear drives the second gear to rotate in the opposite direction, which in turn causes the second gear to drive the turntable to rotate in the opposite direction to the ring, so that the fan housing and the grinding disc rotate in opposite directions, thereby improving the grinding efficiency of the fan housing.

[0016] 2. In this utility model, the dust collection groove collects the debris sliding down the inclined surface of the base, and the dust discharge hole discharges the debris from the dust collection groove. Then, the dust collection box collects the debris discharged from the dust discharge hole, so that the debris generated during grinding can be collected in time, reducing the intensity of manual collection and reducing the impact on subsequent grinding.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a grinding device for processing fan housings, including a dust collection box 1. A base 4 is fixedly connected to the top side of the dust collection box 1. A rotating ring 8 is rotatably connected to the top side of the base 4. A mechanical arm 9 is fixedly connected to the outer wall of the rotating ring 8. The rotating ring 8 causes the mechanical arm 9 to rotate. A grinding disc 10 for grinding is fixedly connected to the top of the mechanical arm 9. A turntable 11 is rotatably connected to the top side of the rotating ring 8. A fan housing 5 is connected to the middle of the turntable 11. A rod 12 is fixedly connected to the middle of the turntable 11. Four limiting rods 13 are fixedly connected to the outer wall of the rod 12. The tops of the rod 12 and the limiting rods 13 are inserted into the middle of the fan housing 5. The fan housing 5 is fixed on the turntable 11 by inserting the rod 12 and the limiting rods 13 into the middle of the fan housing 5.

[0025] Reference Figure 1 , Figure 2 and Figure 4A first gear 15 is rotatably connected to the top side of the base 4. A telescopic rod 16 is fixedly connected to the bottom end of the outer wall of the first gear 15. One end of the telescopic rod 16 is fixedly connected to the inner wall of the rotating ring 8. The rotating ring 8 is driven to rotate by the telescopic rod 16 connected to the first gear 15. The telescopic rod 16 can also compensate for the problem caused by the first gear 15 not being at the center of the turntable 11. A second gear 17 is fixedly connected to the middle of the bottom side of the turntable 11. The bottom end of the limiting rod 13 is fixedly connected to the inside of the second gear 17. The second gear 17 and the first gear 15 mesh with each other. The first gear 15 drives the second gear 17 to rotate, thereby causing the turntable 11 to rotate. The interior of the base 4... A motor 14 is installed, and the drive end of the motor 14 is fixedly connected to the bottom side of the first gear 15. The motor 14 drives the first gear 15 to rotate. A dust collection groove 6 is provided on the bottom side of the outer wall of the base 4. The dust collection groove 6 collects the debris that slides down from the inclined surface of the base 4. Multiple dust discharge holes 7 are provided inside the dust collection groove 6. The debris in the dust collection groove 6 is discharged through the dust discharge holes 7. A dust collection box 3 is provided inside the dust collection box 1. A handle 2 for pulling the dust collection box 3 is fixedly connected to the right side of the dust collection box 3. The dust collection box 3 collects the debris discharged from the dust discharge holes 7. The dust collection box 3 is pulled out of the dust collection box 1 by the handle 2, thereby cleaning the debris in the dust collection box 3.

[0026] Working principle: First, place the fan housing 5 onto the base 4. When placing the fan housing 5 onto the base 4, insert the insertion rod 12 and the limiting rod 13 into the middle of the fan housing 5 to fix it onto the turntable 11. Then, start the motor 14 to drive the first gear 15 to rotate. When the first gear 15 rotates, the telescopic rod 16 will rotate around the first gear 15, causing the rotating ring 8 to rotate on the base 4. When the telescopic rod 16 rotates to an angle farther away from the first gear 15, the telescopic rod 16 will extend, allowing the rotating ring 8 to continue rotating. When the telescopic rod 16 rotates to a position closer to the first gear 15, the telescopic rod... 16 will retract, thus not affecting the rotation of the rotating ring 8. At the same time, the first gear 15 will drive the second gear 17 to rotate in the opposite direction, which in turn causes the second gear 17 to drive the turntable 11 to rotate in the opposite direction to the rotating ring 8. This causes the fan housing 5 and the grinding disc 10 to rotate in opposite directions, thereby improving the grinding efficiency of the fan housing 5. The debris generated during grinding will slide down the inclined surface of the base 4 into the dust collection groove 6, and then fall into the dust collection box 3 in the dust collection box 1 through the dust discharge hole 7. When the dust collection box 3 is full, the operator can pull the handle 2 to pull the dust collection box 3 out of the dust collection box 1 to clean the debris in the dust collection box 3.
