[0023] The present invention also discloses a welding method of a welding device for processing ship accessories, comprising the following steps:

[0024] S1. When welding ship parts, first position the welded parts in the equipment, adjust the position of the welded parts so that the welding point is directly below the welding head. When welding, the lifting platform can be directly controlled to descend, driving the walking welded parts mechanism to descend as a whole until the walking wheels contact the welded parts surface;

[0025] S2. Turn on the adjustment motor to drive the adjustment screw to rotate, control the overall movement of the moving seat, drive the welding head to move, and the welding head realizes the welding process of the weldment. In this process, as the walking wheel rolls on the welding surface, the walking wheel will change its position according to the flatness of the weldment surface, and can synchronously drive the welding gun connected to it to move synchronously, so that the welding head can always maintain the same height as the welding area, and is not affected by the flatness of the weldment surface.

Then, the welding head can realize welding of the weldment.

[0027] S4. During this process, the movable wheel will also move on the weldment, and the movable wheel can drive the second installation sleeve to rotate synchronously, thereby driving the telescopic block and the weld seam knocking arc block to rotate synchronously.

After welding is completed, the synchronous processing of the weld seam can also be completed;

[0028] S5. During the welding process, the meshing gear ring can mesh with the built-in rack, and the meshing gear ring can drive multiple spoiler fans to rotate. When the multiple spoiler fans rotate, airflow can be generated. These airflows flow rapidly through the airflow grooves on the inner wall of the thermal sleeve, thereby assisting the cleaning plate in cleaning the surface of the weldment. At the same time, during the welding process, a large amount of heat emitted from the welding area can also be concentrated on the inner side of the thermal sleeve, and the hot air flow will also flow rapidly due to the spoiler, ensuring that the welding area of ​​the weldment is fully heated, which is conducive to the formation of the weld. After the welding is completed, the push cylinder can be opened and the welded material can be pushed out through the discharge port using the push plate.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. In the present invention, a walking welding mechanism is provided in a supporting manner. When welding ship accessories, the welding piece is first positioned and installed in the equipment, and the position of the welding piece is adjusted so that the welding point is located directly below the welding head. When welding, the lifting platform can be directly controlled to descend, driving the walking welding mechanism to descend as a whole until the walking wheel contacts the surface of the weldment. At this time, the adjusting motor is turned on to drive the adjusting screw to rotate, control the overall movement of the moving seat, drive the displacement of the welding head, and the welding head realizes the welding treatment of the weldment. In this process, as the walking wheel rolls on the welding surface, the walking wheel will change its position with the flatness of the weldment surface, and can synchronously drive the welding gun connected thereto to move synchronously, so that the welding head can always maintain the same height as the welding area, and is not affected by the flatness of the weldment surface. Wait for the walking wheel to finish walking on the weldment surface, and then the welding is completed. Through this design, it can be realized that during welding, the position of the welding head changes with the flatness of the weldment surface, ensuring that the spacing between the welding head and the welding area of ​​the weldment is constant, thereby stably improving the overall welding effect of the equipment, and no manual and intelligent control is required, thereby improving the actual application effect of the equipment.

[0031] 2. In the present invention, a weld processing component is provided. When welding the weldment, the movable seat is controlled to move from left to right. At this time, the cleaning plate can synchronously clean the welding area of ​​the weldment to sweep away impurities accumulated on the weldment. Subsequently, the welding head can realize welding of the weldment. During this process, the movable wheel will also move on the weldment. The movable wheel can drive the second mounting sleeve to rotate synchronously, thereby driving the telescopic block and the weld knocking arc block to rotate synchronously. Every time the second mounting sleeve rotates one circle, the weld knocking arc block can complete the knocking of the weld in the post-welding area. After welding is completed, the synchronous processing of the weld can also be completed. Through this design, not only can the synchronous cleaning processing of the welding area of ​​the weldment be realized before welding to ensure the cleanliness of the welding area, but also the synchronous processing of the weld can be realized during the welding process, thereby stably improving the strength of the weld and improving the overall welding quality of the weldment.

[0032] 3. In the present invention, a spoiler component and a thermal protection component are provided in a matching manner. During the welding process, the meshing gear ring can mesh with the built-in rack, and the meshing gear ring can drive multiple spoiler fans to rotate. When the multiple spoiler fans rotate, airflow can be generated. These airflows flow rapidly through the airflow grooves on the inner wall of the thermal protection sleeve, thereby assisting the cleaning plate in cleaning the surface of the weldment. At the same time, during the welding process, a large amount of heat emitted from the welding area can also be concentrated on the inner side of the thermal protection sleeve, and the hot air flow can also flow rapidly due to the spoiler, ensuring that the welding area of ​​the weldment is fully heated, which is beneficial to the formation of the weld and improves the welding quality. After the welding is completed, the push cylinder can be opened and the welded material can be pushed out through the discharge port using the push plate. BRIEF DESCRIPTION OF THE DRAWINGS

Two walking wheels 1524 are symmetrically arranged about the longitudinal center plane of the welding gun 151.

[0049] The specific implementation method is as follows: when welding ship accessories, the welding part is first positioned and installed in the equipment, and the position of the welding part is adjusted so that its welding point is located directly below the welding head 154. When welding, the lifting platform 12 can be directly controlled to descend, driving the walking welding part mechanism 15 to descend as a whole until the walking wheel 1524 contacts the surface of the weldment. At this time, the adjusting motor 3 is turned on to drive the adjusting screw 8 to rotate, control the overall movement of the moving seat 6, and drive the welding head 154 to move. The welding head 154 realizes the welding processing of the weldment. In this process, as the walking wheel 1524 rolls on the welding surface, the walking wheel 1524 will change its position with the flatness of the weldment surface, and can synchronously drive the welding gun 151 connected thereto to move synchronously, so that the welding head 154 can always maintain the same height as the welding area, and is not affected by the flatness of the weldment surface. Wait for the walking wheel 1524 to finish walking on the weldment surface, and then the welding is completed.

[0050] Through this design, the position of the welding head can be changed as the flatness of the weld surface changes during welding, ensuring that the distance between the welding head and the welding area of ​​the weld is constant, thereby stably improving the overall welding effect of the equipment without the need for manual and intelligent control, thereby improving the actual application effect of the equipment.

[0051] The welding gun 151 is provided with a weld processing assembly 153 fixedly mounted on its outer sleeve. The weld processing assembly 153 includes a first mounting sleeve 1534.

[0052] The specific implementation method is as follows: when welding the weldment, the movable seat 6 is controlled to move from left to right. At this time, the cleaning plate 1533 can synchronously clean the welding area of ​​the weldment to sweep away the impurities accumulated on the weldment. Subsequently, the welding head 154 can realize the welding of the weldment. During this process, the movable wheel 1537 will also move on the weldment. The movable wheel 1537 can drive the second mounting sleeve 1538 to rotate synchronously, thereby driving the telescopic block 1539 and the weld knocking arc block 15310 to rotate synchronously. Every time the second mounting sleeve 1538 rotates one circle, the weld knocking arc block 15310 can complete the knocking of the weld in the area after welding.

[0057] The specific implementation method is as follows: during the welding process, the meshing gear ring 142 can mesh with the built-in rack 10, and the meshing gear ring 142 can drive multiple spoiler fans 143 to rotate. When the multiple spoiler fans 143 rotate, airflow can be generated. These airflows flow rapidly through the airflow grooves 111 on the inner wall of the thermal protection sleeve 113, thereby assisting the cleaning plate 1533 in cleaning the surface of the weldment. At the same time, during the welding process, a large amount of heat emitted from the welding area can also be concentrated on the inner side of the thermal protection sleeve 113, and the hot air flow will also flow rapidly due to the spoiler, ensuring that the welding area of ​​the weldment is fully heated, which is beneficial to the formation of the weld and improves the welding quality. After the welding is completed, the push cylinder 43 can be opened and the push plate 41 can be used to push the welded material out through the discharge port 9.

[0058] The present invention also discloses a welding method of a welding device for processing ship accessories, comprising the following steps:

[0059] S1. When welding ship parts, first position the welded parts in the equipment, adjust the position of the welded parts so that the welding point is directly below the welding head 154.

In this process, as the walking wheel 1524 rolls on the welding surface, the walking wheel 1524 will change its position with the flatness of the weldment surface, and can synchronously drive the welding gun 151 connected thereto to move synchronously, so that the welding head 154 can always maintain the same height as the welding area, and is not affected by the flatness of the weldment surface. Wait for the walking wheel 1524 to finish walking on the weldment surface, and then the welding is completed;

[0061] S3. When welding the weldment, the movable seat 6 is controlled to move from left to right. At this time, the cleaning plate 1533 can clean the welding area of ​​the weldment synchronously to sweep away the impurities accumulated on the weldment. Then, the welding head 154 can weld the weldment.

[0062] S4. During this process, the movable wheel 1537 will also move on the weldment, and the movable wheel 1537 can drive the second installation sleeve 1538 to rotate synchronously, thereby driving the telescopic block 1539 and the weld seam knocking arc block 15310 to rotate synchronously. Whenever the second installation sleeve 1538 rotates one circle, the weld seam knocking arc block 15310 can complete the knocking of the weld seam in the area after welding. After welding is completed, the synchronous processing of the weld seam can also be completed;

[0063] S5. During the welding process, the meshing gear ring 142 can mesh with the built-in rack 10, and the meshing gear ring 142 can drive the multiple spoiler fans 143 to rotate. When the multiple spoiler fans 143 rotate, airflow can be generated. These airflows flow rapidly through the airflow grooves 111 on the inner wall of the thermal protection sleeve 113, thereby assisting the cleaning plate 1533 in cleaning the surface of the weldment. At the same time, during the welding process, a large amount of heat emitted from the welding area can also be concentrated on the inner side of the thermal protection sleeve 113, and the hot air flow will also flow rapidly due to the spoiler, ensuring that the welding area of ​​the weldment is fully heated, which is conducive to the formation of the weld. After the welding is completed, the push cylinder 43 can be opened and the push plate 41 can be used to push the welded material out through the discharge port 9.

[0064] Working principle: When welding ship parts, first position and install the welded parts in the equipment, adjust the position of the welded parts so that the welding point is located directly below the welding head 154. When welding, the lifting platform 12 can be directly controlled to descend, driving the walking welded parts mechanism 15 to descend as a whole until the walking wheel 1524 contacts the surface of the welded parts; turn on the adjusting motor 3, drive the adjusting screw 8 to rotate, control the overall movement of the moving seat 6, drive the welding head 154 to move, and the welding head 154 realizes the welding processing of the welded parts. In this process, as the walking wheel 1524 rolls on the welding surface, the walking wheel 1524 will change its position with the flatness of the welded parts surface, and can synchronously drive the welding gun 151 connected thereto to move synchronously, so that the welding head 154 can always maintain the same height as the welding area, and will not be affected by the flatness of the welded parts surface. Wait for the walking wheel 1524 to finish walking on the welded parts surface, and then the welding is completed;

[0065] When welding the weldment, the movable seat 6 is controlled to move from left to right. At this time, the cleaning plate 1533 can synchronously clean the welding area of ​​the weldment to sweep away the impurities accumulated on the weldment. Then, the welding head 154 can realize the welding of the weldment. In this process, the movable wheel 1537 will also move on the weldment. The movable wheel 1537 can drive the second installation sleeve 1538 to rotate synchronously, thereby driving the telescopic block 1539 and the weld seam knocking arc block 15310 to rotate synchronously. Whenever the second installation sleeve 1538 rotates one circle, the weld seam knocking arc block 15310 can complete the knocking of the weld seam in the area after welding. After the welding is completed, the synchronous processing of the weld seam can also be completed.

[0066] During the welding process, the meshing gear ring 142 can mesh with the built-in rack 10, and the meshing gear ring 142 can drive the multiple spoiler fans 143 to rotate. When the multiple spoiler fans 143 rotate, airflow can be generated. These airflows flow rapidly through the airflow grooves 111 on the inner wall of the thermal protection sleeve 113, thereby assisting the cleaning plate 1533 in cleaning the surface of the weldment. At the same time, during the welding process, a large amount of heat dissipated in the welding area can also be concentrated on the inner side of the thermal protection sleeve 113, and the hot air flow will also flow rapidly due to the spoiler, ensuring that the welding area of ​​the weldment is fully heated, which is conducive to the formation of the weld. After the welding is completed, the push cylinder 43 can be opened and the push plate 41 can be used to push the welded material out through the discharge port 9.
