Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel grooving, and in particular to a honeycomb panel grooving device. Background Technology

[0002] A honeycomb panel is a board made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material. It is also called a honeycomb sandwich structure. In addition, a honeycomb panel also refers to a panel that welds a large number of cutoff waveguides together to form a cutoff waveguide array, creating a large opening area and preventing electromagnetic wave leakage.

[0003] Currently, aluminum honeycomb panels are needed in the aerospace field. Specialized grooving equipment is required when grooving aluminum honeycomb panels. During use, the grooving equipment drives the drill bit to rotate and move at high speed. Since the bottom of the drill bit is set in a conical shape, it can open a 45-degree groove in the honeycomb panel, which helps to splice the honeycomb panel as a whole. However, the inventor found in actual operation that after the V-shaped groove is opened, burrs are prone to appear on the grooved part of the aluminum plate on the upper surface. These burrs can easily puncture the skin of workers during splicing, posing a certain safety hazard. Therefore, a honeycomb panel grooving device is proposed to address the above problems. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a honeycomb panel grooving device, wherein a grinding wheel moves inside the V-groove to grind the middle core of the honeycomb panel inside the V-groove, and a grinding ring is provided on the outer side of the grinding wheel to grind the grooved part of the upper aluminum plate for burr removal, which helps the subsequent operators to splice the panels.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a honeycomb panel grooving device, including grooving equipment;

[0006] The grooving equipment has an internal platform for placing honeycomb panels;

[0007] The grooving equipment is also equipped with a fixed chuck, which contains a grooving drill bit for grooving purposes.

[0008] The bottom of the fixed clamp is rotatably connected to a rotating ring arranged in a ring shape;

[0009] A hydraulic push rod is fixedly connected to one side of the bottom of the rotating ring. An elastic mechanism is fixedly connected to the free end of the hydraulic push rod. A fixed frame is fixedly connected to the bottom of the elastic mechanism. A second motor is fixedly connected inside the fixed frame. A grinding wheel is fixedly connected to the end of the main shaft of the second motor.

[0010] Specialized grooving equipment is required when grooving aluminum honeycomb panels. During operation, the equipment drives a drill bit to rotate and move at high speed. Because the bottom of the drill bit is conical, it can create 45-degree grooves in the honeycomb panel, facilitating overall splicing. However, the inventors discovered in practice that after creating the V-shaped groove, burrs easily appear on the upper surface of the aluminum plate where the groove is located. These burrs can easily puncture the skin of workers during splicing, posing a safety hazard. To address this, a new equipment is installed. A grinding wheel is located on one side of the grooving drill bit. After the drill bit completes the grooving, a second motor drives the grinding wheel to rotate. The grinding wheel can move inside the V-shaped groove to grind the core of the honeycomb panel within the groove. A grinding ring is also located on the outer side of the grinding wheel to grind the grooved area of ​​the upper aluminum plate, aiding in subsequent splicing operations.

[0011] Furthermore, a first motor is fixedly connected to the side of the fixed chuck, a drive gear is fixedly connected to the end of the main shaft of the first motor, a gear ring meshes with the side of the drive gear, and a rotating ring is fixedly connected to the inner side of the gear ring.

[0012] Furthermore, symmetrically arranged grinding rings are fixedly connected to both sides of the grinding wheel, and a grinding layer is provided around the outer edge of the grinding rings.

[0013] Furthermore, the grinding wheel is disc-shaped, and its outer periphery is pointed.

[0014] As the grooving drill moves, its grooving orientation needs to be changed at any time. The first motor drives the drive gear to rotate, the drive gear drives the gear ring to rotate, and the gear ring drives the rotating ring to rotate. At this time, the hydraulic push rod can drive the elastic mechanism and the fixed frame to rotate, so that the grinding wheel can be re-matched with the groove for subsequent grinding and deburring work.

[0015] Furthermore, the elastic mechanism includes a mounting frame that is fixedly connected to the rotating ring, a sliding plate that is slidably connected inside the mounting frame, a connecting rod that is fixedly connected to the bottom of the sliding plate, and the bottom of the connecting rod that is fixedly connected to the fixed frame.

[0016] The outer side of the mounting frame is embedded inside the fixed frame and is slidably connected to the fixed frame.

[0017] Furthermore, a spring is fixedly connected to the top of the sliding plate, and the other end of the spring is fixedly connected to the mounting frame.

[0018] An elastic mechanism is provided between the hydraulic push rod and the fixed frame, which can provide a certain buffer to prevent the fixed frame from driving the second motor and the grinding wheel to excessively squeeze the honeycomb panel and cause damage.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] A grinding wheel is provided on one side of the grooving drill bit. After the grooving drill bit completes the grooving, it drives the grinding wheel to rotate through the second motor. The grinding wheel can move inside the V-groove and is used to grind the core of the honeycomb panel inside the V-groove. A grinding ring is provided on the outside of the grinding wheel to grind the grooved part of the upper aluminum plate, which helps the subsequent operators to splice the parts.

[0021] As the grooving drill bit moves, its grooving orientation needs to be changed at any time. The first motor drives the drive gear to rotate, the drive gear drives the gear ring to rotate, and the gear ring drives the rotating ring to rotate. At this time, the hydraulic push rod can drive the elastic mechanism and the fixed frame to rotate, so that the grinding wheel can be re-matched with the groove for subsequent grinding and deburring work.

[0022] An elastic mechanism is provided between the hydraulic push rod and the fixed frame, which can provide a certain buffer to prevent the fixed frame from driving the second motor and the grinding wheel to excessively squeeze the honeycomb panel and cause damage. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example

[0031] The slotting equipment 1 is equipped with a placement platform 2 for placing honeycomb panels;

[0032] The grooving equipment 1 is also equipped with a fixed chuck 3, and the fixed chuck 3 is equipped with a grooving drill bit 4 for grooving purposes.

[0033] The bottom of the fixed clamp 3 is rotatably connected to a rotating ring 8 arranged in a ring shape;

[0034] A hydraulic push rod 10 is fixedly connected to one side of the bottom of the rotating ring 8. An elastic mechanism 9 is fixedly connected to the free end of the hydraulic push rod 10. A fixed frame 11 is fixedly connected to the bottom of the elastic mechanism 9. A second motor 12 is fixedly connected inside the fixed frame 11. A grinding wheel 13 is fixedly connected to the end of the main shaft of the second motor 12.

[0035] Specialized grooving equipment is required when grooving aluminum honeycomb panels. During use, the grooving equipment drives the drill bit to rotate and move at high speed. Since the bottom of the drill bit is conical, it can create 45-degree grooves in the honeycomb panel, which helps with the overall splicing of the honeycomb panel. However, the inventors found in actual operation that after the V-shaped groove is created, burrs are prone to appear on the grooved part of the aluminum plate on the upper surface. These burrs can easily puncture the skin of workers during splicing, posing a certain safety hazard. When the power is turned on, a grinding wheel 13 is set on one side of the grooving drill bit 4. When the grooving drill bit 4 is grooving, the second motor 12 drives the grinding wheel 13 to rotate. The grinding wheel 13 can move inside the created V-shaped groove to grind the core of the honeycomb panel inside the V-shaped groove. A grinding ring 14 is set on the outer side of the grinding wheel 13 to grind the grooved part of the upper aluminum plate, which helps the subsequent operators to splice the panels.

[0036] The hydraulic push rod 10 can drive the elastic mechanism 9 and the fixed frame 11 to move, which is used for grinding honeycomb panels of different thicknesses.

[0037] A first motor 5 is fixedly connected to the side of the fixed chuck 3. A drive gear 6 is fixedly connected to the end of the main shaft of the first motor 5. A gear ring 7 meshes with the side of the drive gear 6. A rotating ring 8 is fixedly connected to the inner side of the gear ring 7.

[0038] Grinding rings 14 are fixedly connected to both sides of the grinding wheel 13 and are arranged symmetrically. A grinding layer is provided around the outer edge of the grinding rings 14.

[0039] The grinding wheel 13 is arranged in a disc shape, and the outer periphery of the grinding wheel 13 is pointed.

[0040] As the grooving drill bit 4 moves, its grooving orientation needs to be changed at any time. The first motor 5 drives the drive gear 6 to rotate, the drive gear 6 drives the gear ring 7 to rotate, and the gear ring 7 drives the rotating ring 8 to rotate. At this time, the hydraulic push rod 10 can drive the elastic mechanism 9 and the fixed frame 11 to rotate, so that the grinding wheel 13 is located behind the advancing end of the grooving drill bit 4, so that the grinding wheel 13 is re-matched with the groove for subsequent grinding and deburring work.

[0041] The outer edge of the grinding wheel 13 is set with a pointed tip to ensure contact with the honeycomb core inside the groove, so as to achieve the purpose of thorough grinding. The outer side of the grinding ring 14 is provided with a grinding layer, which is used to grind the burrs on the edges of the grooved aluminum plate.

[0042] The elastic mechanism 9 includes a mounting frame 901 that is fixedly connected to the rotating ring 8. A sliding plate 902 is slidably connected inside the mounting frame 901. A connecting rod 903 is fixedly connected to the bottom of the sliding plate 902. The bottom of the connecting rod 903 is fixedly connected to the fixed frame 11.

[0043] The outer side of the mounting frame 901 is embedded inside the fixed frame 11 and is slidably connected to the fixed frame 11.

[0044] A spring 904 is fixedly connected to the top of the sliding plate 902, and the other end of the spring 904 is fixedly connected to the mounting frame 901.

[0045] An elastic mechanism 9 is provided between the hydraulic push rod 10 and the fixed frame 11, which can provide a certain buffer for the fixed frame 11 and prevent the fixed frame 11 from driving the second motor 12 and the grinding wheel 13 to excessively squeeze the honeycomb panel and cause damage.

[0046] The action of spring 904 ensures that the grinding wheel 13 is in close contact with the honeycomb core inside the V-groove. Even if the hydraulic push rod 10 is pushed excessively to a certain extent, damage to the honeycomb panel can be avoided.

[0047] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
