Description

Technical Field

[0001] This utility model belongs to the field of FFU fan volute production technology, specifically relating to an FFU fan volute burr removal device. Background Technology

[0002] The volute of the FFU fan is a key structural component in the FFU. It is named for its spiral profile, which resembles a snail shell. It is usually made of sheet metal or engineering plastic and is used to house the fan impeller. It guides airflow through a specific cross-sectional shape and spiral design.

[0003] However, during the production of FFU fan casings, due to the inherent characteristics of processing techniques such as stamping, welding, and cutting, burrs are easily left on the edges, inner wall corners, and welded joints of the casing. Although these burrs may seem minor, they can scratch the filter sealing strips during subsequent processing, leading to potential air leakage during installation. During operation, they can also interfere with airflow organization, causing turbulence and noise, and even adsorbing dust particles, seriously affecting the air delivery efficiency and cleanliness of the FFU. Therefore, burr removal equipment is needed to remove the burrs.

[0004] To address the aforementioned problems, this application proposes a burr removal device for the volute casing of an FFU (Fan Filter Unit). Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an FFU fan volute burr removal device, which features the ability to easily remove burrs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a burr removal device for FFU fan casing, comprising a support plate, two first electric push rods arranged above the support plate, each first electric push rod having a limit plate fixedly connected to its telescopic end, a support column arranged on the right side of the support plate, a sliding plate arranged above the support column, a controller fixedly connected to the front of the support column, a sliding frame fixedly connected to the top of the support column, the inner wall of the sliding frame being slidably connected to the outer surface of the sliding plate, a second electric push rod arranged above the sliding plate, a third electric push rod fixedly connected to the inner wall of the sliding plate, a fixed frame arranged at the telescopic end of the third electric push rod, a brush rod rotatably connected to the inner wall of the fixed frame, a rotary motor arranged on the front of the fixed frame, and the power output end of the rotary motor being fixedly connected to the end of the brush rod near the controller.

[0007] As a preferred embodiment of this utility model, the bottom surface of the support plate is fixedly connected to two sets of connecting columns, and the bottom end of each connecting column is fixedly connected to a support base.

[0008] As a preferred embodiment of this utility model, each of the two first electric push rods is fixedly connected to an assist plate on one side away from each other, and the bottom surface of each assist plate is fixedly connected to the upper surface of the support plate.

[0009] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the bottom end of the support column, and the left side of the fixing plate is fixedly connected to the right side of the support plate.

[0010] As a preferred embodiment of this utility model, a connecting frame is fixedly connected to the outer surface of the second electric push rod, and the bottom surface of the connecting frame is fixedly connected to the upper surface of the sliding frame.

[0011] As a preferred embodiment of this utility model, the telescopic end of the second electric push rod is fixedly connected to a connecting plate, and the bottom surface of the connecting plate is fixedly connected to the upper surface of the sliding plate.

[0012] As a preferred embodiment of this utility model, a reinforcing ring is fixedly connected to the outer surface of the telescopic end of the third electric push rod, and the bottom surface of the reinforcing ring is fixedly connected to the upper surface of the fixing frame.

[0013] As a preferred embodiment of this utility model, a fixed base is fixedly connected to the upper surface of the rotary motor, and the back of the fixed base is fixedly connected to the front of the fixed frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a support plate to provide a placement platform for the FFU fan volute, and by using the telescopic action of the first electric push rod to drive the limiting plate, the volute can be precisely limited and fixed on the support plate. At the same time, the controller can realize the start-stop control and rotation direction adjustment of the equipment, making operation convenient. When it is necessary to remove burrs, the telescopic action of the third electric push rod drives the fixing frame, brush rod and rotary motor to move downward, so that the brush rod contacts the surface of the volute. Then the rotary motor drives the brush rod to rotate at high speed, and the burrs are removed through friction. In addition, the telescopic action of the second electric push rod can drive the sliding plate to slide laterally in the sliding frame, thereby driving the grinding component to move along the surface of the volute, realizing all-round and dead-angle burr removal operation, effectively improving the efficiency and uniformity of deburring. Compared with traditional manual grinding or single-direction mechanical processing, it has the advantages of high automation, wide coverage and controllable operation precision.

A rotary motor 20 is arranged on the front of the fixed frame 17, and the power output end of the rotary motor 20 is fixedly connected to the end of the brush rod 18 near the controller 9.

[0024] In this embodiment, the controller 9 adopts a PLC, which realizes logic, sequence, timing and other operations through a programmable memory to accurately control the mechanical device and production process. Meanwhile, the brush rod 18 is made of high-strength aluminum alloy and is anodized, which is both lightweight and corrosion-resistant. Its outer ring brush structure adopts a composite weaving process of hard alloy wire and nylon wire. The hard alloy wire is responsible for cutting burrs, while the nylon wire takes into account the polishing and cleaning functions. It can improve the surface smoothness while removing burrs from the volute and ensure the stable operation of the equipment.

[0025] Specifically, two sets of connecting columns 4 are fixedly connected to the bottom surface of the support plate 1. Each connecting column 4 is fixedly connected to a support base 3 at its bottom end. In this embodiment, the support base 3 can be fixed to the support plate 1 through the connecting columns 4, and the support plate 1 can be placed stably by using the support base 3.

[0026] Specifically, each of the two first electric push rods 6 has a booster plate 5 fixedly connected to one side away from each other. The bottom surface of each booster plate 5 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the booster plate 5 can fix the first electric push rod 6 to the support plate 1, thereby enabling the first electric push rod 6 to extend and retract stably.

[0027] Specifically, a fixing plate 7 is fixedly connected to the bottom end of the support column 8. The left side of the fixing plate 7 is fixedly connected to the right side of the support plate 1. In this embodiment, the fixing plate 7 can fix the support column 8 to the support plate 1 and make the support column 8 stable to use.

[0028] Specifically, a connecting frame 13 is fixedly connected to the outer surface of the second electric push rod 14. The bottom surface of the connecting frame 13 is fixedly connected to the upper surface of the sliding frame 10. In this embodiment, the connecting frame 13 can fix the second electric push rod 14 to the sliding frame 10 and make the second electric push rod 14 sturdy.

[0029] Specifically, the telescopic end of the second electric push rod 14 is fixedly connected to a connecting plate 11, and the bottom surface of the connecting plate 11 is fixedly connected to the upper surface of the sliding plate 12. In this embodiment, the second electric push rod 14 and the sliding plate 12 can be fixed through the connecting plate 11, thereby driving the sliding plate 12 to slide.

[0030] Specifically, a reinforcing ring 16 is fixedly connected to the outer surface of the telescopic end of the third electric push rod 15. The bottom surface of the reinforcing ring 16 is fixedly connected to the upper surface of the fixed frame 17.

[0031] Specifically, a fixing seat 19 is fixedly connected to the upper surface of the rotary motor 20. The back of the fixing seat 19 is fixedly connected to the front of the fixing frame 17. In this embodiment, the rotary motor 20 can be fixed by the fixing seat 19. The rotary motor 20 is a power device that converts electrical energy into mechanical energy and drives the rotating parts to rotate continuously through the principle of electromagnetic induction.

[0032] The working principle and usage process of this utility model are as follows: First, the FFU fan casing is placed stably on the support plate 1. The controller 9 activates the first electric push rod 6, whose telescopic end drives the limiting plate 2 to move towards each other until the casing is precisely clamped and positioned. Subsequently, the second electric push rod 14 drives the sliding plate 12 to move smoothly within the sliding frame 10 via the connecting plate 11, achieving precise horizontal positioning of the brush rod 18. Simultaneously, the third electric push rod 15 synchronously drives the fixing frame 17 vertically downward, causing the brush rod 18 to contact the surface of the casing to be treated with a set pressure. At this time, the rotary motor 20 drives the brush rod 18 to rotate at high speed, and its composite brush of hard alloy wire and nylon wire rotates synchronously. After deburring and surface polishing are completed, the second electric push rod 14 and the third electric push rod 15 move in coordination according to the preset trajectory under the precise coordination of the PLC controller 9, ensuring that the brush rod 18 can cover complex areas such as the edge of the volute and the corner of the inner wall without dead angles. When the polishing operation is completed, each drive mechanism resets in sequence. The third electric push rod 15 drives the brush rod 18 to rise and detach from the workpiece. The second electric push rod 14 drives the sliding plate 12 to return to the initial position. The first electric push rod 6 retracts and releases the limit plate 2, and the operator can easily take out the processed workpiece. The whole process is fully automated by relying on the PLC controller 9, which significantly improves the deburring efficiency and surface quality consistency.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
