Description

Technical Field

[0001] This utility model relates to the field of cutting and adsorption technology, specifically an adsorption fixture for automatic laser cutting of bulletproof helmet linings. Background Technology

[0002] Bulletproof helmets are one of the core pieces of equipment for individual soldier protection. Their protective performance and wearing comfort are of paramount importance. As the part that comes into direct contact with the user's head, the helmet liner not only has the function of cushioning impact and dispersing pressure, but also directly affects the comfort of wearing it for a long time. Modern high-performance bulletproof helmet liners are mostly made of high-polymer composite materials and are precisely cut and shaped. Their shapes are complex and curved to meet the requirements of ergonomic design.

[0003] Currently, the main technical challenges in laser cutting helmet liners with complex curved surfaces are as follows: Because the liner material has an irregular curved surface, traditional fixture positioning methods struggle to achieve stable, dead-angle-free clamping. During processing, workpiece displacement or deformation can easily lead to decreased cutting accuracy and even scrap. Furthermore, most existing fixtures are inadequate for precise and efficient positioning, severely impacting the automation level and production efficiency of laser cutting. In addition, conventional vacuum adsorption fixtures are typically rigid planes or simple curved surfaces, failing to conform well to the complex internal curved surface of the helmet liner, resulting in uneven adsorption force distribution. Under processing stress, some areas may loosen due to weak adsorption, while other areas may deform due to excessive pressure, affecting the final cutting quality. Utility Model Content

[0004] This invention provides an adsorption fixture for automatic laser cutting of bulletproof helmet linings. Through the combined use of a top adsorption mechanism and a side adsorption mechanism, adaptive flexible adsorption can be achieved, resulting in high-precision and stable fixation. The side adsorption mechanism, composed of a connecting ball joint, a top spring, and a side adsorption plate, combined with the top adsorption plate, forms an adsorption and fixation system that automatically adapts to the complex curved surface inside the helmet lining. When the lining is placed, under the action of the spring force, the side adsorption plates can adaptively adjust their angle to tightly fit the sidewall of the lining, ensuring maximum adsorption surface. Subsequently, a unified negative pressure system simultaneously evacuates all adsorption plates, achieving all-round, dead-angle-free flexible wrapping and fixation, effectively avoiding cutting errors caused by lining displacement or deformation, and providing a high-precision and stable reference for subsequent laser cutting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adsorption fixture for automatic laser cutting of bulletproof helmet linings, comprising:

[0011] Furthermore, the rotating mechanism includes an angle-adjusting motor and a rotating base.

[0017] (1) The adsorption fixture for automatic laser cutting of bulletproof helmet lining can achieve adaptive flexible adsorption and high-precision stable fixation by using the top adsorption mechanism and the side adsorption mechanism in combination. The side adsorption mechanism, which is composed of a ball joint, a top spring and a side adsorption plate, combined with the top adsorption plate, forms an adsorption and fixation system that can automatically adapt to the complex curved surface inside the helmet lining. When the lining is placed, the side adsorption plate can adaptively adjust its angle under the action of the spring force to fit tightly against the side wall of the lining and ensure that the adsorption surface is maximized. Then, the uniform negative pressure system simultaneously evacuates all adsorption plates to achieve flexible wrapping and fixation in all directions without dead angles, effectively avoiding cutting errors caused by lining displacement or deformation, and providing a high-precision stable reference for subsequent laser cutting.

[0030] In this implementation scheme: the top adsorption plate 10 controls the suction force inside the top adsorption plate 10 through the pressure control component to complete the adsorption and positioning of the top of the bulletproof helmet liner to be cut. At the same time, when the bulletproof helmet liner is placed on the cap support mechanism, the connecting ball joint 16 adjusts the angle of the side adsorption plate 7 so that the side adsorption plate 7 fits against the inner wall of the bulletproof helmet liner, and the pressure control mechanism adjusts the internal pressure synchronously to complete the positioning of the bulletproof helmet liner.

[0031] Specifically, the rotating mechanism includes an angle-adjusting motor 2 and a rotating seat 3. The angle-adjusting motor 2 is rotatably connected to the top of the base 1, and the rotating seat 3 is fixedly connected to one side of the top of the base 1, with one end of the rotating seat 3 fixedly connected to the output end of the angle-adjusting motor 2.

[0032] In this embodiment, the model of the angle adjustment motor 2 can be selected from those available on the market as needed, which will not be elaborated here. The angle adjustment motor 2 controls the rotating seat 3 to rotate, thereby adjusting the angle of the bulletproof helmet liner on the helmet support mechanism, which facilitates laser cutting.

[0033] Specifically, the cap support mechanism includes a support base 5, a bottom support 6, and a top support 9. The support base 5 is fixedly connected to the top center of the rotating base 3, the bottom support 6 is fixedly connected to the top of the support base 5, and multiple support columns 8 are fixedly connected to the top of the bottom support 6. The top support 9 is fixedly connected to the top of the multiple support columns 8.

[0034] In this embodiment: the support base 5 creates a certain height between the base 6 and the rotating base 3, and the support column 8 lifts the top support 9 to complete the use of bulletproof helmet liners of different sizes.

[0036] In this embodiment, the model of the adsorption air pump 4 can be selected from those available on the market as needed, which will not be elaborated here. Through the use of the adsorption air pump 4 and the main air pipe 11, the negative pressure control of the top adsorption plate 10 is completed.

[0037] Specifically, the guiding components include a guide movable tube 13 and a guide positioning tube 14. A telescopic groove 17 is provided on one side of the outer surface of the base 6.

[0039] Specifically, the ejection component includes a top spring 15, one end of which is fixedly connected to the telescopic groove 17, and the other end of which is fixedly connected to one end of the guide tube 13. The end of the guide tube 13 is provided with a cavity, which is connected to the adsorption air pump 4 through the side telescopic air pipe 12 to complete pressure control. The connecting ball joint 16 rotates in the cavity to ensure that the side adsorption plate 7 is always connected to the cavity so as to complete adsorption.

[0040] In this embodiment: the position of the guide tube 13 is controlled by the elastic force of the top spring 15, thus enabling the use of the side suction plate 7.

[0041] In use, the bulletproof helmet liner is placed on the top support 9. Due to gravity, the bottom of the bulletproof helmet liner presses against the top adsorption plate 10, while the side presses against the side adsorption plate 7. Through the cooperation of the top spring 15 and the connecting ball joint 16, the side adsorption plate 7 is made to fit against the inner wall of the bulletproof helmet liner. After completion, the adsorption air pump 4 controls the air pressure of the top adsorption plate 10 and the side adsorption plate 7 through the main air pipe 11 and the side telescopic air pipe 12 to complete the positioning of the bulletproof helmet liner on the top support 9 and the bottom support 6. After positioning, the angle adjustment motor 2 controls the rotating seat 3 to adjust the angle for laser cutting.
