[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figure 1-Figure 7 The welding device for ship accessories shown in the figure comprises a workbench 1, a mounting plate 101 is fixedly connected to the top of the workbench 1, a mounting frame 102 is fixedly connected to one side of the mounting plate 101, a limiting structure 2 is arranged on the top of the workbench 1, and a welding structure 3 is arranged on the bottom of the mounting frame 102; wherein the welding structure 3 comprises a second electric push rod 301 arranged on the top of the mounting frame 102, the output shaft of the second electric push rod 301 passes through the mounting frame 102 and is fixedly connected to a fixing block 302, and the bottom of the fixing block 302 is opened. A groove 316 is provided, a turntable 303 is provided on the surface of the fixed block 302, a connecting ring 315 is fixedly connected to the inner side of the turntable 303, the connecting ring 315 is slidably connected to the surface of the fixed block 302, an integrally formed connecting portion 304 is provided on the surface of the turntable 303, a slide groove 305 extending to the surface of the turntable 303 is opened on the surface of the connecting portion 304, a welding gun body 306 is provided inside the slide groove 305, and a guide assembly 31 for guiding the movement of the welding gun body 306 is fixedly connected to one side of the mounting plate 101.

[0029] The ship parts to be welded are placed on the surface of the workbench 1. After being limited by the limiting structure 2, the second electric push rod 301 is started to drive the fixed block 302 to move downward. During this process, the turntable 303 is driven to move downward synchronously through the connecting ring 315, so that the welding gun body 306 is close to the parts to be processed. During this process, the top of the T-shaped block to be welded with the parts to be processed can be inserted into the groove 316. The second electric push rod 301 is used to drive the fixed block 302 to move downward to limit and fix it to prevent it from shifting. The operation is simple and does not require staff to fix it, which effectively improves the welding efficiency.

[0030] like Figure 1-Figure 7 As shown, a mounting seat 307 is fixedly connected to the surface of the welding gun body 306, and the mounting seat 307 is slidably connected to the top of the connecting part 304, and a limiting rod 308 is fixedly connected to the surface of the mounting seat 307, and a baffle is fixedly connected to the top of the connecting part 304, and the other end of the limiting rod 308 passes through the baffle.

[0031] A spring 309 is sleeved on the surface of the limiting rod 308 , one end of the spring 309 is fixedly connected to the surface of the mounting seat 307 , and the other end of the spring 309 is fixedly connected to the surface of the baffle.

[0032] An inner gear ring 317 is fixedly connected to the inner side of the turntable 303 , and the inner gear ring 317 is slidably connected to the inner wall of the fixed block 302 . A motor 313 is arranged inside the fixed block 302 , and a gear 314 meshing with the inner gear ring 317 is fixedly connected to the output shaft of the motor 313 .

[0033] A mounting bar 311 is fixedly connected to the surface of the mounting seat 307 . The mounting bar 311 and the limiting rod 308 are symmetrically distributed with the mounting seat 307 as the center. The other end of the mounting bar 311 is fixedly connected to the guide rod 310 . The lower end of the guide rod 310 passes through the slide groove 305 .

[0034] A guide rod 312 is fixedly connected to the surface of the mounting seat 307 , and the included angle between the guide rod 312 and the limiting rod 308 is 90 degrees.

[0035] By starting the motor 313, the gear 314 can be driven to rotate, thereby driving the internal gear ring 317 connected thereto to rotate, and then driving the turntable 303 to make the welding gun body 306 rotate around the fixed block 302. During this process, the guide rod 310 can contact the surface of the welding accessory, and the surface contour of the welding accessory is used to push the guide rod 310 to adjust the position of the mounting seat 307. By setting the spring 309, the guide rod 310 can always fit the surface contour of the welding accessory, so that the welding gun body 306 and the welding accessory maintain a good distance, and after one rotation, the effect of welding the two accessories together can be achieved without secondary welding. This avoids the situation in which the existing welding method can only perform single-side welding due to the limitation of the clamp after fixing the two accessories, and manual flipping and secondary welding are required to complete the welding operation. This avoids the poor welding effect caused by discontinuous welding, effectively ensures the continuity of welding, and improves the welding effect.

[0036] like Figure 1-Figure 7 As shown, the guide assembly 31 includes a fixed plate 3101 arranged on one side of the mounting plate 101, and evenly distributed mounting columns 3104 are fixedly connected between the fixed plate 3101 and the mounting plate 101. A guide plate 3102 is fixedly connected to the other side of the fixed plate 3101, and the cross-sectional shape of the guide plate 3102 is approximately "J" shaped.

[0037] A guide block 3103 located inside the guide plate 3102 is fixedly connected to the surface of the fixed plate 3101 , a guide cavity is formed between the surface of the guide block 3103 and the guide plate 3102 , and the guide rod 312 extends into the interior of the guide cavity.

[0038] When the second electric push rod 301 drives the fixed block 302 to move upward, the guide rod 312 can slide along the inner wall of the guide cavity, so that when it moves to the highest point, it drives the mounting seat 307 away from the fixed block 302 under the pressure of the inner wall of the guide cavity, so that when the fixed block 302 is moved down again, the guide rod 310 can be close to the surface of the accessory under the action of the spring 309, thereby improving the applicability of the device and being able to be used for welding accessories of different specifications.

[0039] like Figure 1-Figure 7 As shown, the limiting structure 2 includes two connecting blocks 201 which are respectively arranged on both sides of the workbench 1 and are symmetrically distributed, a bidirectional screw rod 205 is arranged between the two connecting blocks 201, and two mounting blocks 206 are threadedly connected on the surface of the bidirectional screw rod 205, a clamping block 207 is fixedly connected to one side of the mounting block 206, and a slot 208 is provided on the surface of the clamping block 207, and a mounting rod 202 is also fixedly connected between the two connecting blocks 201, and the mounting block 206 is slidably connected to the mounting rod 202, and a positioning plate 204 located below the mounting frame 102 is fixedly connected to the top of the workbench 1.

[0040] Two first electric push rods 203 are disposed on the other side of the workbench 1 , and the output shafts of the first electric push rods 203 are fixedly connected to the surface of the connecting block 201 .

[0041] By starting the first electric push rod 203, the positions of the two connecting blocks 201 can be adjusted under the action of the first electric push rod 203, so that the positions of the mounting block 206 and the clamping block 207 can be adjusted by using the bidirectional screw rod 205, and the initial clamping of the accessories can be achieved in cooperation with the positioning plate 204. The setting of the card slot 208 can facilitate the clamping process of the arc plate accessories. By rotating the bidirectional screw rod 205 to adjust the positions of the two mounting blocks 206, the fixation of arc plates of different sizes can be achieved, and the operation is simple.

[0042] Working principle: Place the ship parts to be welded on the surface of the workbench 1, limit them by the limiting structure 2, start the second electric push rod 301 to drive the fixed block 302 to move downward, and in this process drive the turntable 303 to move downward synchronously through the connecting ring 315, so that the welding gun body 306 is close to the parts to be processed. In this process, the top of the T-shaped block to be welded with the parts to be processed can be inserted into the inside of the groove 316, and the second electric push rod 301 is used to drive the fixed block 302 to move downward to limit and fix it to prevent it from shifting. The operation is simple and does not require staff to fix it, which effectively improves the welding efficiency. Then, by starting the motor 313, the gear 314 can be driven to rotate, thereby driving the internal gear ring 317 connected thereto to rotate, and then driving the turntable 303 to make the welding gun body 3 06 rotates around the fixed block 302. During this process, the guide rod 310 can contact the surface of the welding accessory, and the surface contour of the welding accessory is used to push the guide rod 310 to adjust the position of the mounting seat 307. By setting the spring 309, the guide rod 310 can always fit the surface contour of the welding accessory, so that the welding gun body 306 maintains a good distance from the welding accessory, and the two accessories can be welded together after one rotation without secondary welding. This avoids the situation in which the existing welding method can only perform single-side welding due to the limitation of the clamp after fixing the two accessories, and requires manual flipping and secondary welding to complete the welding operation. This avoids the poor welding effect caused by discontinuous welding, effectively ensures the continuity of welding, and improves the welding effect.
