Description

Technical Field

[0001] This utility model relates to the field of composite material plate processing technology for civil aircraft or general aviation aircraft, and in particular to a heat dissipation device for drilling SCF composite material laminates. Background Technology

[0002] Laminated structures are the most basic type of composite material structure for aircraft. They consist of a series of layers of fiber prepregs arranged in different directions, with interlayer matrix material sandwiched between each layer. This structure has advantages such as light weight, high strength, and high stiffness, and is widely used in aircraft wings, skins, tail fins, and other structural components.

[0003] Laminates require drilling during processing, but prolonged drilling may cause smoke. This is because heat is concentrated inside the hole during hole formation, preventing heat from dissipating and causing smoke. Additionally, failure to remove debris from the hole during drilling can also lead to smoke. Therefore, it is necessary to clean and dissipate heat from the hole cavity in a timely manner.

[0004] To address this issue, we propose a heat dissipation device for drilling SCF composite laminates. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By configuring a fan, air inlet hood, air outlet pipe, connecting pipe, blowing pipe, first blowing head, connecting pipe, groove, air inlet channel, annular pipe, second blowing head, air inlet pipe, electric rod, moving plate, limiting rod, sleeve, and corrugated pipe, when the drill bit is drilling a hole in the SCF composite laminate, the fan, in conjunction with several first blowing heads, can blow air horizontally to the drilling position. At the same time, the electric telescopic rod pushes the chip shield downward and covers the drilling position. By activating the electric rod, the moving plate is moved horizontally to the left, so that the sleeve can be fitted onto the air inlet pipe. The fan can then blow air into the annular pipe, and with the setting of several second blowing heads, air can be blown into the hole cavity. In addition, by blowing air into the air inlet channel through the connecting pipe, the area below the drilled laminate can be cooled simultaneously. This not only removes chips from the drilled hole cavity but also cools and dissipates heat at the drilling position, preventing overheating and smoke during the drilling process.

[0015] 2. The chip shield is moved downward by the electric telescopic rod to cover the drilling position. This prevents wood chips from flying everywhere when the drill bit passes through the through hole and drills into the plywood. Under the action of several first blowers, the wood chips are blown to the left inside the chip shield. The chip guide is set to guide the wood chips into the chip collection box. This not only prevents wood chips from flying everywhere during drilling, but also reduces the workload of the staff in cleaning up the wood chips later. Attached Figure Description

[0021] Please see Figures 1 to 4 The present invention provides the following technical solution:

[0022] A heat dissipation device for drilling SCF composite laminate includes a base 1, a fixed seat 3 fixedly connected to the top rear side of the base 1, a cylinder 4 mounted on the fixed seat 3, a lifting plate 5 slidably connected to the inner wall of the fixed seat 3 and a drive motor 6 mounted at the bottom of the lifting plate 5, a drill bit 7 fixedly connected to the power output end of the drive motor 6, a U-shaped seat 2 slidably connected to the base 1 and located below the drill bit 7, a pressing mechanism in the inner cavity of the U-shaped seat 2, a fan box 12 fixedly connected to the right side of the U-shaped seat 2 and a fan 13 mounted on the right wall of the fan box 12.

The other end of the air outlet pipe 15 passes through the left side wall of the bellows 12 and extends to the inner cavity of the U-shaped seat 2. A blower pipe 17 is provided at the lower left corner of the bellows 12, and a connecting pipe 16 is inserted and fixed to the top of the blower pipe 17. The top end of the connecting pipe 16 is inserted and fixed to the air outlet pipe 15. Several first blower heads 18 are equidistantly arranged on the left side of the blower pipe 17, and the left ends of the several first blower heads 18 all pass through the left side wall of the bellows 12 and extend to the inner cavity of the U-shaped seat 2. A cover mechanism is provided between the U-shaped seat 2 and the drill bit 7.

[0023] The pressing mechanism includes two pressure plates 37 and several pressure feet 38 equidistantly arranged at the bottom of the two pressure plates 37. The two pressure plates 37 are slidably connected to the front and rear side walls of the inner cavity of the U-shaped seat 2. Two symmetrical hydraulic push rods 36 are arranged on the front and rear sides of the inner cavity of the U-shaped seat 2, and the power end of the hydraulic push rod 36 is fixedly connected to the top of the adjacent pressure plate 37. The pressure plate 37 is pushed vertically downward by the hydraulic push rod 36, so that the laminate can be pressed with the arrangement of several pressure feet 38, thereby improving the drilling quality.

[0024] The covering mechanism includes a chip shield 10, which is located between the drill bit 7 and the U-shaped seat 2. The width of the chip shield 10 is the same as the width of the inner cavity of the U-shaped seat 2. A through hole is provided at the middle of the top of the chip shield 10.

The right end of the limit rod 24 is fixedly connected to the left side wall of the air box 12. When the chip baffle 10 is attached to the upper surface of the laminated plate, the electric rod 20 is activated to push the moving plate 21 to move horizontally to the left, so that the sleeve 22 can be sleeved onto the air inlet pipe 27, so that the wind generated by the fan 13 when it is working is delivered into the annular pipe 25, and several second blowers 26 blow up the wood chips in the cavity to prevent the wood chips from accumulating in the cavity.

[0026] A groove 39 is provided at the middle of the bottom of the inner cavity of the U-shaped base 2, and an air inlet channel 11 connected to the inner cavity of the groove 39 is provided on the right side of the U-shaped base 2. A connecting pipe 19 is inserted and fixed to the bottom of the blower pipe 17, and the other end of the connecting pipe 19 passes through the bottom of the air box 12 and extends to the inner cavity of the air inlet channel 11. Some of the air can be blown upward from the air inlet channel 11 and the groove 39, so as to cool the lower surface of the laminate. At the same time, the wood chips that fall into the inner cavity of the groove 39 can be blown out.

[0027] A chip collection box 28 is provided on the bottom left side of the U-shaped base 2, and a handle is welded to the left side of the chip collection box 28. Sliders are fixedly connected to the four corners of the bottom of the chip collection box 28. Two open slide grooves with front and back symmetry are opened on the top left side of the base 1. Each slider is slidably connected to the inner cavity of the adjacent open slide groove, which makes it easy to remove the chip collection box 28 from the base 1. With the setting of the chip collection box 28, the wood chips that fall when several first blowers 18 blow to the left can be collected.

[0028] A chip guide cover 29 is provided on the top left side of the chip collection box 28. Movable shafts 30 are fixedly connected to both the front and rear sides of the chip guide cover 29. Support plates 31 are rotatably connected to opposite ends of the two movable shafts 30. The right side of the support plate 31 is fixedly connected to the U-shaped seat 2. A horizontal plate 32 is fixedly connected to the front side of the chip guide cover 29, and an L-shaped rod 33 is slidably connected to the horizontal plate 32. A blind hole 34, adapted to the L-shaped rod 33, is opened on the top of the support plate 31 located on the front side, and the longest end of the L-shaped rod 33 is inserted into the blind hole 34. The inner cavity of the L-shaped rod 33 is fixedly connected to the limit block 35 near the bottom of the front side. When the wood chips in the inner cavity of the chip baffle 10 are blown to the left, the wood chips falling from the inner cavity can be directly guided into the chip collection box 28, reducing the labor intensity of the workers cleaning the wood chips. In addition, when the workers are loading the laminate, they can first pull the L-shaped rod 33 out of the inner cavity of the blind hole 34, and then flip the chip guide cover 29 to rotate counterclockwise around the movable shaft 30, thereby preventing the chip guide cover 29 from obstructing the normal loading and unloading of the laminate.

[0029] Working Principle: In use, the operator first places the SCF composite laminate into the bottom of the U-shaped seat 2, and then moves the pressure plate 37 downward by activating the hydraulic push rod 36. This allows several pressure feet 38 to press the SCF composite laminate firmly. Next, the electric telescopic rod 9 is activated to move the chip shield 10 downward, covering the upper surface of the SCF composite laminate. Immediately afterward, the electric rod 20 is activated to move the moving plate 21 horizontally to the left, attaching the sleeve 22 to the outside of the right end of the air inlet pipe 27. Then, the cylinder 4 is activated to move the lifting plate 5 vertically downward, causing the drill bit 7 to pass through the through-hole cavity and contact the SCF composite laminate. When the drive motor 6 is activated, the drill bit 7 rotates to the point where drilling can be performed on the SCF composite laminate. The chip shield 10 effectively prevents sawdust from flying everywhere during drilling. Simultaneously with the activation of the drive motor 6, the fan 13 is also activated, which removes external sawdust. Air is drawn into the air inlet hood 14 and then transported through the air outlet duct 15 into the annular pipe 25, the blowing pipe 17, and the connecting pipe 19. The air transported into the annular pipe 25 is blown into the cavity of the drilled hole through several second blowers 26, thereby raising the sawdust generated in the cavity. The arrangement of several first blowers 18 creates a right-to-left airflow within the inner cavity of the U-shaped base 2, thus transporting the sawdust to the left side of the inner cavity of the U-shaped base 2. Furthermore, the airflow is directed through the connecting pipe 19 to the air inlet channel 11 and the concave... The inner cavity of groove 39 supplies air, which can both blow air to dissipate heat on the lower surface of the laminate and blow up a small amount of wood chips that fall into the inner cavity of groove 39, improving the thoroughness of wood chip removal. By cooling the drilled hole cavity from multiple directions, it can prevent overheating and smoke during the drilling process. The chip guide cover 29 can guide the wood chips into the chip collection box 28, making it convenient for workers to remove the chip collection box 28 from the base 1 and clean the wood chips collected in its inner cavity.
