Description

Technical Field

[0001] The invention belongs to the technical field of helmet processing, in particular to a drilling device for processing protective gear helmets. Background Art

[0002] During the helmet production process, holes need to be drilled on the helmet surface using a drilling device for installing the suspension system. The helmet suspension installation holes usually need to be perpendicular to the helmet body to ensure that the suspension system can be installed correctly and perform at its best.

[0003] In existing technology, drilling is often accomplished by securing the helmet, keeping the drill rod pointed toward the helmet, and then moving the drill rod axially. However, helmets are typically not perfectly round, but rather approximately elliptical or oval. Current drilling methods using pistol drills and bench drills often fail to ensure the mounting holes are perpendicular to the helmet surface at that point, making them prone to slipping and deviation. This leads to significant errors in drilling position accuracy, making it difficult to secure mounted accessories (such as suspension mounts and cameras) and prone to loosening or falling off. Therefore, improvements have been developed to address these issues. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, the present invention provides a drilling device for processing protective gear and helmets, including a frame mechanism 1 composed of a fixed plate 101, a first piston rod 102, a first connecting plate 103, a connecting rod 104 and a second connecting plate 105, wherein the fixed plate 101 and the first connecting plate 103 are connected by a ball shaft of the first piston rod 102, and the first connecting plate 103 and the second connecting plate 105 are fixedly connected by the connecting rod 104, and further comprising:

[0031] A drilling mechanism 2 is provided on the first connecting plate 103 and is used to drill holes in the surface of the helmet;

[0032] Sealing mechanism 4, which is provided in the middle of the second connecting plate 105;

[0033] Suction cup 5, which is mounted on the bottom of the sealing mechanism 4 and is used to absorb the surface of the helmet;

[0034] The first piston sleeve 3 is distributed in an annular shape and the ball shaft connects the first connecting plate 103 and the suction cup 5;

[0035] The straightening mechanism 6 is arranged on the top of the first connecting plate 103 and is connected to the first piston sleeve 3, and is used for resetting the first piston sleeve 3.

[0036] The above scheme is adopted: by positioning first and then drilling, the purpose of making the hole perpendicular to the helmet surface is achieved. During positioning, the suction cup 5 is covered at the hole position to achieve negative pressure adsorption and fixation. When the device is not perpendicular to the helmet surface, the first piston sleeve 3 will be compressed, and the internal gas will enter the straightening mechanism 6. By starting the drilling mechanism 2, the straightening mechanism 6 can be driven to inject gas back into the first piston sleeve 3 during drilling. While ensuring the negative pressure of the suction cup 5, the first connecting plate 103 is parallel to the cross-section of the drilled hole by expanding multiple first piston sleeves 3, thereby achieving the perpendicularity of the drilled hole to the helmet.

[0037] The fixed plate 101 can be mounted on a machine tool arm, or a handle can be installed to form a gun drill to achieve manual drilling.

[0038] like Figure 2 、 4As shown, the drilling mechanism 2 includes an electric telescopic rod 201, a positioning plate 202, a drive motor 203 and a drill rod 204. The electric telescopic rod 201 is installed in the middle of the bottom of the first connecting plate 103. The bottom of the positioning plate 202 is fixed to the drive motor 203 and its upper end is slidingly connected to the first connecting plate 103. The drill rod 204 is installed on the output shaft of the drive motor 203. In the initial state, the first connecting plate 103 is extended to the maximum value, and the top surface of the positioning plate 202 is coplanar with the bottom surface of the fixed plate 101.

[0039] The above solution is adopted: the electric telescopic rod 201 is coaxial with the sealing mechanism 4 in the length direction, which is convenient for precise positioning. When the electric telescopic rod 201 is started, it can drive the positioning plate 202 and the drive motor 203 to move downward synchronously, which not only realizes the movement and drilling of the drill rod 204, but also can squeeze the straightening mechanism 6 to allow the internal gas to enter the first piston sleeve 3 to realize the reset of the first piston sleeve 3.

[0040] like Figure 5 As shown, the sealing mechanism 4 includes a fixed tube 401, a fixed ring plate 402 and a frustum 403. The fixed tube 401 is fixedly connected to the second connecting plate 105, the fixed ring plate 402 is installed on the inner wall of the fixed tube 401, and the frustum 403 is installed on the drill pipe 204 and can be in sealing contact with the fixed ring plate 402.

[0041] With the above solution, in the initial state, the fixed ring plate 402 and the cone 403 are in sealed contact, so that the suction cup 5 can obtain sufficient negative pressure when it is in close contact with the helmet surface. In the best case, the horizontal spacing area between the bottom surface of the cone 403 and the fixed tube 401 should be equal to the area of ​​the inner ring of the fixed ring plate 402, so that the airflow can flow fully.

[0042] An infrared transmitter may also be provided at the bottom of the cone 403 to perform positioning via infrared rays.

[0043] like Figure 4 As shown, the straightening mechanism 6 includes a second piston sleeve 601, a spring 602 and a high-pressure hose 603. The second piston sleeve 601 is installed on the top of the first connecting plate 103. The spring 602 elastically connects the second piston sleeve 601 and the positioning plate 202. The high-pressure hose 603 connects the first piston sleeve 3 and the second piston sleeve 601.

[0044] The above solution is adopted: when the first piston sleeve 3 is compressed, the second piston sleeve 601 is extended, and a certain amount of redundancy can be provided by the provided spring 602. When the electric telescopic rod 201 pushes the positioning plate 202 to move, the positioning plate 202 can squeeze the second piston sleeve 601 through the spring 602 to compress it. When the positioning plate 202 is pushed to the maximum value by the electric telescopic rod 201, the second piston sleeve 601 and the spring 602 are both compressed to the maximum value, which can ensure that the lengths of all first piston sleeves 3 are equal, and the first connecting plate 103 is parallel to the cross-section of the hole on the surface of the helmet.

[0045] like Figure 6 、 7 As shown, it also includes a negative pressure mechanism 8, which includes a fixed shell 801, fan blades 802 and a second filter plate 803. The fixed shell 801 is installed on the inner wall of the fixed tube 401, the fan blades 802 are connected to the bearings of the fixed shell 801 and are slidably connected to the drill rod 204, and the second filter plate 803 is installed at the bottom of the fixed shell 801, and the fan blades 802 are located between the fixed shell 801 and the second filter plate 803.

[0046] With the above solution, the fan blades 802 are configured to rotate synchronously with the rotation of the drill rod 204, thereby maintaining a negative pressure between the fan blades 802 and the suction cup 5. This design is because when drilling, the drill rod 204 moves downward, causing the fixed ring plate 402 to separate from the frustum 403, and the negative pressure effect of the suction cup 5 disappears. By introducing the fan blades 802, the suction cup 5 can still maintain the negative pressure effect, close to the helmet, and ensure stability during drilling;

[0047] The second filter plate 803 is conical in shape, and debris is generated when drilling to prevent the debris from affecting the fan blades 802. At the same time, the debris can be discharged upward by wind through the side of the second filter plate 803 and the fixed shell 801.

[0048] like Figure 3 As shown, it also includes a collecting mechanism 7, which includes a closing plate 701, a connecting pipe 702, a collecting bin 703 and a first filter plate 704. The closing plate 701 is installed on the top of the inner cavity of the fixed pipe 401, the connecting pipe 702 is symmetrically installed on both sides of the closing plate 701 and connected to the inner wall of the fixed pipe 401, the collecting bin 703 is fixedly connected to the connecting pipe 702, and the first filter plate 704 is installed on the collecting bin 703.

[0049] The above solution is adopted: the provided closing plate 701 is used to position the drill rod 204, and also cooperates with the connecting tube 702 to achieve the closure of the top of the fixed tube 401, so that the debris generated by drilling can enter the collection bin 703 through the connecting tube 702 for collection, and the first filter plate 704 is detachable, which is convenient for discharging debris after long-term use.

[0050] The working principle and use process of the present invention:

[0051] When in use, first place the suction cup 5 over the surface of the helmet where the hole is to be drilled, and apply pressure to the helmet so that the suction cup 5 can absorb the helmet. When the cross section of the hole is not perpendicular to the fixing tube 401, the first piston sleeve 3 will be compressed, and the internal gas will be discharged into the second piston sleeve 601 through the high-pressure hose 603;

[0052] Then, the fixed plate 101 is kept in position, and the electric telescopic rod 201 and the drive motor 203 are started synchronously. The electric telescopic rod 201 drives the positioning plate 202, the drive motor 203 and the drill rod 204 to move downward. The positioning plate 202 squeezes the second piston sleeve 601 through the spring 602, so that the internal gas of the second piston sleeve 601 flows back into the first piston sleeve 3, and the first piston sleeve 3 gradually recovers its length. Since the suction cup 5 is in close contact with the surface of the helmet, the extension of the first piston sleeve 3 can drive the first connecting plate 103 to be parallel to the cross-section of the hole. Since the positioning plate 202 moves downward, the first connecting plate 103 can be shortened freely. At this time, the first connecting plate 103 is not parallel to the fixed plate 101.

[0053] Simultaneously, as the drill rod 204 rotates and moves downward, it drives the cone 403 downward, and drives the fan blades 802 to rotate to generate wind force, maintaining negative pressure to enable the suction cup 5 to adsorb the helmet. As the drill rod 204 contacts the helmet to drill, the generated debris enters the connecting pipe 702 and the collection chamber 703 in sequence under the action of negative pressure and is collected;

[0054] When the drilling is completed, since the hole has been formed, the negative pressure adsorption effect of the suction cup 5 disappears, the driving motor 203 is stopped and the positioning plate 202 is driven upward by the electric telescopic rod 201 to restore the device to its original state.
