Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a ship-use steel bracket molding tool capable of molding complex end faces and a use method thereof. Background Art

[0002] During the shipbuilding stage, there are many various pipes and plate brackets fixed on the complex three-dimensional structure of the hull in the ship's engine room. When matching the root end face of the bracket with the complex three-dimensional structure, it is necessary to use gas welding for multiple cutting, adjustment, and fitting. During the cutting process, the cross section of the bracket is easily irregular and jagged, which reduces the welding quality and bracket strength, and may even cause the bracket to be scrapped, and consumes a lot of man-hours. At present, in the shipbuilding industry, there are many brackets on complex end faces, especially when the bracket is heavy, the operation is very cumbersome. Summary of the invention

[0003] According to the technical problems raised above, a tool for molding a steel bracket for ships that can mold complex end faces and a method for using the tool are provided, which solves the problem that molding brackets on complex three-dimensional structures is cumbersome, time-consuming and of low quality.

[0004] The technical means adopted by the present invention are as follows:

[0005] A steel bracket marking tool for ships capable of marking complex end faces, comprising a main moving mechanism, a marking needle and a marking needle moving mechanism, wherein the marking needle is installed in the marking needle moving mechanism, and the marking needle moving mechanism is installed at the bottom of the main moving mechanism, wherein the main moving mechanism is used to complete the height adjustment of the marking needle moving mechanism, and the marking needle moving mechanism is used to adjust the fixed state of the marking needle, wherein the number of the marking needles is several, and in the working state, each marking needle can contact the complex end face to be marked.

[0006] Furthermore, the main moving mechanism includes a first connecting structure and a second connecting structure, the first connecting structure and the second connecting structure are arranged relative to each other, and strip holes are arranged on the center lines of the two. After the positions of the first connecting structure and the second connecting structure are determined, the relative positions of the two are limited by the first stud and the first butterfly nut.

[0007] Furthermore, the needle removal mechanism includes a first steel belt and a second steel belt, which are combined to form a hole for installing the needle. The root of the needle can be fixed inside the hole, and the first steel belt and the second steel belt are connected by a plurality of second studs and second butterfly nuts. In the working state, after confirming that the needle is in contact with the complex end face to be marked, the relative positions of the first steel belt and the second steel belt are limited by the second studs and the second butterfly nuts.

[0008] Furthermore, the hole shape inside the first steel belt and the second steel belt is a square hole, and the needle is a square steel needle, and the cross-sectional area at the top end is larger than the cross-sectional area of ​​the needle body.

[0009] Furthermore, at least one type of needle removal needle is provided with a bend at its lower end.

[0010] Furthermore, in the main moving mechanism, a pad is provided above the plate at a high position.

[0011] Furthermore, after press-fitting, rubber pads and steel plates are arranged on the outside of the steel belt, and then installed by means of studs and butterfly nuts.

[0012] The present invention also discloses a method for using the above-mentioned steel bracket type extraction tool, comprising the following steps:

[0013] Step 1, loosen the first butterfly nut to allow the first connection structure and the second connection structure to slide relative to each other. At the position where the bracket is needed, adjust the approximate height so that the mold-taking needle can be extended and retracted to a length sufficient to mold a complex end surface. After adjustment, tighten the first butterfly nut;

[0014] Step 2, loosen the second butterfly nut, so that the tip of the needle can fully contact the complex end surface under the action of gravity, and then fix the second butterfly nut;

[0015] Step 3: Place the fixed steel bracket cutting tool close to the profile to be cut, and draw the position indicated by the cutting needle tip on the profile;

[0016] Step 4: Remove the profiling tool, connect the profiling points with smooth curves, and then cut them to complete the profiling of the complex end face of the bracket.

[0017] Compared with the prior art, the present invention has the following advantages: Currently, there are no special tools on site, and workers have to cut multiple times based on their experience, which is time-consuming and labor-intensive, and has poor quality. The present invention can take points on a complex end face and connect them into lines, so that the line where the steel bracket on the complex end face contacts the complex end face can be easily taken out. With this tool, the end face can be taken out at one time, saving time and effort, and improving the installation quality. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0034] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0035] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0036] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0037] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0038] like Figures 1 to 11 As shown, an embodiment of the present invention discloses a steel bracket removal tool for ships that can remove complex end faces, including a main moving mechanism, a removal needle and a needle removal action mechanism, wherein the removal needle is installed in the needle removal action mechanism, and the needle removal action mechanism is installed at the bottom of the main moving mechanism, and the main moving mechanism is used to complete the height adjustment of the needle removal action mechanism, and the needle removal action mechanism is used to adjust the fixed state of the removal needle, and the number of the removal needles is several, and in the working state, each removal needle can contact the complex end face to be marked. In this embodiment, the needle removal action mechanism is arranged on the main moving mechanism at the lower height.

[0039] The main moving mechanism includes a first connecting structure and a second connecting structure, the first connecting structure and the second connecting structure are arranged opposite to each other, and a strip hole, i.e., a runway-shaped oblong hole 12, is arranged on the midline of the first connecting structure and the second connecting structure. After the positions of the first connecting structure and the second connecting structure are determined, the relative positions of the two are limited by the first stud 3 and the first butterfly nut 4. In this embodiment, the first connecting structure and the second connecting structure are angle steels, i.e., the first angle steel 1 and the second angle steel 2. The first angle steel and the second angle steel can slide only along the direction of the oblong hole in cooperation with the oblong hole and the stud, and the relative position of the first angle steel and the second angle steel can be tightened by fixing the butterfly nut.

[0040] The needle removal mechanism includes a first steel belt 6 and a second steel belt 11. The first steel belt and the second steel belt are combined to form a hole for installing the needle. The root of the needle can be fixed inside the hole. The first steel belt and the second steel belt are connected by a plurality of second studs 9 and second butterfly nuts 10. In the working state, after confirming that the needle is in contact with the complex end face to be marked, the relative positions of the first steel belt and the second steel belt are limited by the second studs and the second butterfly nuts.

[0041] The holes inside the first and second steel strips are square holes, and the needle is a square steel needle 5, the cross-sectional area at the top of the upper part is larger than the cross-sectional area of ​​the needle body, which plays a role of limiting the position, so that the needle will not fall off.

[0042] At least one of the needles has a bend at its lower end, which allows the needle tip and the angle steel to be in the same plane, increases the accuracy of the needle removal, and can better fit the profile bracket that needs to be removed, making it easier to remove the needle.

[0043] In the main moving mechanism, a backing plate 13 is provided above the plate at the high position.

[0044] After press-fitting, rubber pads 7 and steel plates 8 are placed on the outside of the steel strip, and then installed through studs and butterfly nuts. The steel plate and rubber pads mainly play the role of fixing the needle. When the needle is removed, the studs and butterfly nuts are tightened to fix the needle. The rubber pad can better fix the needle.

[0045] The present invention also discloses a method for using the above-mentioned steel bracket type extraction tool, comprising the following steps:

[0046] Step 1, loosen the first butterfly nut to allow the first connection structure and the second connection structure to slide relative to each other. At the position where the bracket is needed, adjust the approximate height so that the mold-taking needle can be extended and retracted to a length sufficient to mold a complex end surface. After adjustment, tighten the first butterfly nut;

[0047] Step 2, loosen the second butterfly nut, so that the tip of the needle can fully contact the complex end surface under the action of gravity, and then fix the second butterfly nut;

[0048] Step 3: Place the fixed steel bracket cutting tool close to the profile to be cut, and draw the position indicated by the cutting needle tip on the profile;

[0049] Step 4: Remove the profiling tool, connect the profiling points with smooth curves, and then cut them to complete the profiling of the complex end face of the bracket.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
