Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb board production, in particular to a clamping mechanism for producing special-shaped aluminum alloy honeycomb boards. Background Technique

[0002] For aluminum honeycomb boards, due to the high heat conduction value between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized; there are small holes on the honeycomb aluminum skin, enabling the gas inside the board to flow freely; and no structural deformation will occur during thermal expansion and contraction. Currently, the shapes of aluminum honeycomb boards are diverse. During the production of special-shaped aluminum honeycomb boards, auxiliary tooling is usually required to clamp the workpiece. The auxiliary tooling often clamps the side wall of the aluminum plate through clamping jaws. In the production process of special-shaped aluminum alloy honeycomb boards, the selection of the clamping mechanism is crucial for ensuring production efficiency and product quality.

[0003] The lengths and thicknesses of existing honeycomb boards are different, making it inconvenient for the clamping device to adjust and fix left and right according to the length and thickness of the honeycomb board, reducing the stability during processing;

[0004] The existing patent (Publication No.: CN217292236U) discloses an adjustable clamping device for honeycomb board processing. Through the cooperation between a double-headed motor, a lead screw, a threaded seat, and a fixed frame, it is convenient to drive the moving seat to drive the clamping seat to move, and the left and right adjustment and limitation can be carried out according to the length of the honeycomb board. And by driving the clamping plate with a threaded rod, it is convenient to clamp and fix according to the thickness of the honeycomb board, enhancing the practicability.

[0005] In view of the above problems, although the solution given by the existing patent can carry out left and right adjustment and limitation according to the length of the honeycomb board and is convenient to clamp and fix according to the thickness of the honeycomb board, for special-shaped aluminum plates, there is no large flat surface, resulting in difficulty in stably clamping the aluminum plate by the existing auxiliary tooling, large difficulty in fixing the aluminum plate, and low stability. Summary of the Invention

[0006] The purpose of the utility model is to provide a clamping mechanism for producing special-shaped aluminum alloy honeycomb boards, which can make two clamping parts move relatively, so that multiple clamping rods can clamp the uneven special-shaped aluminum alloy honeycomb boards. The clamping rods push the piston to move in the cylinder shell, compressing the nitrogen gas in the sealing shell. These nitrogen gases can push some of the clamping rods with smaller pressure, so that the clamping forces of multiple clamping rods are kept consistent, avoiding inconsistent clamping forces caused by unevenness, so as to solve the problems put forward in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A clamping mechanism for the production of special-shaped aluminum alloy honeycomb panels, including a fixed base, on the upper surface of which an installation frame is fixed.

One end of the clamping rod is fixed with a protective gasket, and the other end of the clamping rod is fixed with a piston.

Detailed Embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a clamping mechanism for the production of special-shaped aluminum alloy honeycomb panels, including a fixed base 1. An installation frame 2 is fixed on the upper surface of the fixed base 1. Two clamping mechanisms for clamping special-shaped aluminum alloy honeycomb panels are installed on the upper surface of the installation frame 2. An adjustment mechanism for adjusting the clamping mechanism is provided inside the installation frame 2. A cleaning mechanism for cleaning the surface of the special-shaped aluminum alloy honeycomb panel is provided on the side wall of the installation frame 2;

[0028] The clamping mechanism includes a clamping member 3. A plurality of clamping rods 31 are telescopically connected inside the clamping member 3. A protective gasket 32 is fixed at one end of the clamping rod 31. A piston 34 is fixed at the other end of the clamping rod 31. A cylinder housing 33 fixedly connected to the clamping member 3 is sleeved on the outer surface of the piston 34. A guide rod 35 is telescopically connected to the inner wall of the clamping rod 31 and close to the piston 34. A spring 36 in contact with the piston 34 is telescopically sleeved on the outer surface of the guide rod 35. A sealing housing 37 is fixed on one side of the clamping member 3. The guide rod 35 is fixedly connected to the sealing housing 37. The end of the spring 36 abuts against the inner wall of the sealing housing 37. The adjustment mechanism includes a first guide groove 4. There are two first guide grooves 4, both of which are opened inside the installation frame 2. A first guide block 41 fixedly connected to the clamping member 3 is slidably connected inside the two first guide grooves 4. A lead screw 42 is threadedly connected inside the first guide block 41. A double-shaft motor 43 is fixed at the input end of the lead screw 42. The double-shaft motor 43 is fixedly connected to the installation frame 2. Two groups of fixing bolts 5 are symmetrically installed inside the fixed base 1.

[0029] By adopting the above technical solution, before using the clamping mechanism for manufacturing the special-shaped aluminum alloy honeycomb board, first place the fixed base 1 in a suitable position and fix the fixed base 1 by tightening the fixing bolts 5 to avoid displacement. When clamping the special-shaped aluminum alloy honeycomb board, place the special-shaped aluminum alloy honeycomb board on the mounting rack 2 so that the special-shaped aluminum alloy honeycomb board is located between the two clamping members 3. Start the double-shaft motor 43, which drives the two lead screws 42 with opposite leads to rotate respectively. At this time, with the cooperation of the first guiding groove 4, the rotation of the lead screw 42 drives the first guiding block 41 to move, thereby driving the two clamping members 3 to move relatively, so that the clamping rods 31 on the clamping members 3 contact the end face of the special-shaped aluminum alloy honeycomb board. Since the end face of the special-shaped aluminum alloy honeycomb board is not smooth, the multiple clamping rods 31 can clamp the uneven special-shaped aluminum alloy honeycomb board. The provided protective gasket 32 can play a protective role, reducing the damage caused by the direct contact between the clamping rods 31 and the special-shaped aluminum alloy honeycomb board. Since the clamping rods 31 can slide inside the clamping members 3, when the clamping rods 31 contact the special-shaped aluminum alloy honeycomb board, the clamping rods 31 push the piston 34 to move inside the cylinder housing 33, and at the same time the piston 34 pushes the spring 36 to move and compress. Since the sealing housing 37 is filled with nitrogen, when the piston 34 moves, the nitrogen in the sealing housing 37 can be compressed. At this time, these nitrogen gases can push some of the clamping rods 31 with relatively small pressure, so that the clamping forces of the multiple clamping rods 31 are kept consistent, avoiding inconsistent clamping forces caused by unevenness. After the processing of the board is completed, the two clamping members 3 return to their original positions. During the process of the spring 36 stretching and resetting itself, it pushes the clamping rods 31 to reset, and the provided guide rod 35 can play a guiding role, thus facilitating the next clamping use.

[0030] Specifically, as Figures 1 - 4 shown, the cleaning mechanism includes a second guiding groove 6, which is opened on the side wall of the mounting rack 2. A second guiding block 61 is slidably connected inside the second guiding groove 6. The second guiding block 61 has a T-shaped structure. The upper surface of the second guiding block 61 is fixed with a mounting plate 62. A fixing plate 63 is fixed in the horizontal direction on the side wall of the mounting plate 62. A cleaning brush 64 is fixed on the lower surface of the fixing plate 63 by screws.

[0031] By adopting the above technical solution, through the second guiding block 61 arranged in the second guiding groove 6, the mounting plate 62 can be manually pulled horizontally, thereby driving the fixing plate 63 to move horizontally, so that the cleaning brush 64 can clean the upper surface of the board, which is convenient for use.

[0032] Working principle: Place the special-shaped aluminum alloy honeycomb panel on the mounting bracket 2 so that the special-shaped aluminum alloy honeycomb panel is between two clamping members 3. The biaxial motor 43 drives two lead screws 42 with opposite threads to rotate. With the cooperation of the first guide groove 4, it drives the two clamping members 3 to move relative to each other, so that the clamping rods 31 on the clamping members 3 contact the end face of the special-shaped aluminum alloy honeycomb panel. Since the end face of the special-shaped aluminum alloy honeycomb panel is not smooth, multiple clamping rods 31 can clamp the uneven special-shaped aluminum alloy honeycomb panel. Since the clamping rods 31 can slide inside the clamping members 3, when the clamping rods 31 contact the special-shaped aluminum alloy honeycomb panel, the clamping rods 31 push the pistons 34 to move inside the cylinder housing 33. Since the sealing housing 37 is filled with nitrogen, when the pistons 34 move, the nitrogen in the sealing housing 37 can be compressed. At this time, this nitrogen can push some of the clamping rods 31 with relatively small pressure, so that the clamping forces of the multiple clamping rods 31 are kept consistent, avoiding inconsistent clamping forces caused by unevenness. During the process of the spring 36 stretching and resetting itself, it pushes the clamping rods 31 to reset. Manually pull the mounting plate 62 in the horizontal direction to drive the fixing plate 63 to move horizontally, and the cleaning brush 64 can clean the upper surface of the plate.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
