[0037] Below we further elaborate on a square material rapid centerline marking tool and marking method of the present invention in combination with the accompanying drawings and specific embodiments, in order to more clearly understand its structural composition and working mode, but this cannot be used to limit the scope of protection of the present invention.

[0038] In shipbuilding, a lot of square material cutting and decomposition work is involved. The most important one is to divide the square material into two from the middle. This involves how to determine the center line of the square material and make clear marks before cutting and decomposing. In order to adapt to square materials of different widths and lengths, and to adapt to different material types, we have designed a special fast marking tool, and based on this, we have designed an operating process to achieve fast marking of the center line of the square material. Common square materials include metal materials such as steel, aluminum, etc., wood materials and plastic materials.

[0039] Example 1

In terms of structural composition, the tool includes a structural body, a marking cone nail 2, a laser emitting device 4, a bearing 3 and a center target 6. The structural body is a columnar body 1, and a marking cone nail 2 is fixed in the middle of the columnar body 1, which runs through the upper and lower parts. The center line of the marking cone nail 2 is located on the center line of the columnar body 1. There are two bearings 3, which are symmetrically arranged on the bottom center line of the structural body and symmetrically arranged relative to the marking cone nail 2. The laser emitting device 4 is coaxially arranged on the top of the marking cone nail 2. The laser emitting device 4 is provided with a laser outlet that can emit a laser beam. The laser emitting device 4 is rotatably located on the marking cone nail 2. The center target 6 is arranged at the center of the end of the square material A. When the tool is installed on the square material A, the laser beam 46 emitted by the laser emitting device 4 is aligned with the center target point position of the center target 6.

[0041] like Figure 1 and Figure 2 As shown, a through hole is provided in the middle of the columnar body 1 as the main body of the structure, and a threaded barrel 5 is provided in the through hole, and the upper part of the threaded barrel 5 is exposed on the upper surface of the columnar body 1. The upper half of the marking cone pin 2 is in the shape of a bolt, and the thread matches the thread of the structure penetrating the threaded barrel 5, and the lower half is in the shape of a cone pin, and the tip is used for marking the surface of the square material A. In order to make the marking clearer, a hole can be provided at the end of the cone pin, and a marker or other similar pigments can be placed in the hole.

[0042] like Figure 1 and Figure 6 As shown, the bearing 3 is fixed to the bottom of the columnar body 1 by a bearing bolt, and non-through threaded holes are symmetrically arranged on both sides below the columnar body 1 with the center of the tooling, that is, the center of the marking cone nail 2, matching the bearing bolts. The marking cone nail 2 can be adjusted to extend in length as needed, so that the cone pin tip of the marking cone nail 2 can extend and directly penetrate the surface of the square material.

[0043] like Figure 3 As shown, the laser emitting device 4 includes a laser emitter 43, a laser rotating body 42, a rotating tightening button 44 and an upper and lower rotating body 41. The upper and lower rotating body 41 is a T-shaped body with a thread at the bottom. The laser rotating body 42 is fixed on the top platform of the T-shaped body. The laser rotator 42 is provided with the laser emitter 43, and the laser emitter 43 emits the laser beam 46 horizontally. The laser emitter 43 is adjustably fixed to the laser rotating body by rotating the locking button 44. A locking upper and lower rotating pin 45 is provided at the bottom of the upper and lower rotating body 41. The bottom of the upper and lower rotating body 41 is installed on the top of the scribing cone nail 2.

[0044] like Figure 4 and Figure 5 As shown, in a tool for quickly marking the center line of a square material of the present invention, as a matching laser alignment device, the bottom of the center target 6 is provided with a corner stud with an external thread, a circular target surface is fixed on the top of the stud, and a plurality of concentric rings and a bull's eye are provided in the middle of the target surface. The center of the concentric ring coincides with the bull's eye and coincides with the center line of the stud, and the corner stud is provided with a tip for screwing into the center position of the end of the square material A.

[0045] Furthermore, a layer of transparent rubber sleeve is provided on the surface of the two bearings 3. Through the design of the transparent rubber sleeve, the bearing can be smoothly scratched on the surface of the square material, so that the marking straightness is higher.

[0046] like Figure 7 As shown, a pressing protrusion 7 is provided on the outside of at least one end of the columnar body 1 as the main body of the structure, and the pressing protrusion 7 is made of plastic. In the case of a clamping angle, by pressing the pressing protrusion 7 from the outside, the rapid centerline marking tool is closer to the surface of the square material A, and more forward power can be provided, making the marking faster.

[0047] Example 2

[0048] This embodiment is a method for quickly marking the center line of a square material. The method uses the above-mentioned fast center line marking tool. The method includes the following steps:

[0049] The first step is to determine the width specification and approximate length of the square material A, and find the end point position where the center line needs to be drawn.

[0050] The second step is to assemble the rapid centerline marking tool according to the specifications of the square material, screw the marking cone nail 2 into the columnar body 1, make the tip of the marking cone nail 2 slightly exposed from the lower surface of the columnar body 1, and fix the laser emitting device 4 on the top of the marking cone nail 2, mark one end of the square material A to find the center position, screw the center target 6 into the center position of the end of the square material A through the tip of the corner stud, and make the center of the target surface be on the vertical plane where the center line of the top of the square material is located.

[0051] The third step is to clamp the rapid square material marking tool on the square material A through the bearing 3 below, so that the two bearings 3 are respectively located on both sides of the square material, adjust the laser emitting device 4 for alignment, start the laser emitter 43, and align the laser beam 46 emitted by the laser emitter 43 to the center position of the center target 6.

[0052] Step 4: Press slightly to push the fast centerline marking tool forward, and use the tip of the bottom of the marking cone pin 2 to mark the upper surface of the square material A, and ensure that the laser beam 46 is always at the center of the center target 6. Figure 6 and Figure 7 As shown, combined with the size of the square material, when the quick centerline marking tool is installed on the square material, it may be stuck on it, that is, the width of the square material is equal to the distance between the two bearings 3. In another case, the width of the square material is smaller than the distance between the two bearings 3. When marking, if the size of the square material is smaller than the middle distance of the bearings, the quick centerline marking tool needs to be rotated by a certain angle as a whole, so that the force between the quick centerline marking tool and the square material is tightened before marking.

[0053] Step 5: The quick centerline marking tool moves to the end of the square material A to complete the marking operation on the upper surface of the square material A. After marking, remove the quick centerline marking tool and cut the square material according to the marked centerline. If the square material needs to be marked on the opposite side or on all four sides, repeat the marking operation with the quick centerline marking tool from one end to the other.

[0054] Step 6. After the construction is completed, organize and store the quick center line marking tool for next use.

[0055] The present invention can not only improve the safety of shipbuilding and reduce the accident rate, but also save a lot of labor hours and improve production efficiency. It can also find the center line of square materials efficiently and beautifully, has low site requirements and strong applicability.
