DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figures 1 to 9The present invention provides a technical solution: a welding device for manufacturing ship accessories, comprising a base 1, two support frames 2 are fixedly connected at one end of the top of the base 1, a plurality of electric rollers 3 are arranged on the top of the support frame 2, a turning mechanism 4 is arranged at the top of the base 1 adjacent to the support frame 2, the turning mechanism 4 comprises a support block 401, a support ring 402 and a rotating column 403, the support block 401 is fixedly connected to the base 1, a support ring 402 is fixedly connected to the top of the support block 401, a rotating column 403 is rotatably connected to the inner wall of the support ring 402, the rotating column 403 is located at one end of the support frame 2 and a driving groove 404 is provided on the side wall, and the driving groove 404 is located at the rotating column At the center of the side wall of the column 403, the rotating column 403 is located at the driving groove 404 and is provided with four transmission grooves 405 around it. The four transmission grooves 405 are evenly distributed in a circular array around the driving groove 404. The rotating column 403 is located at a position adjacent to the transmission groove 405 and is provided with a receiving groove 406; two conveyor belts 407 are provided inside the receiving groove 406, and the two ends of the conveyor belts 407 are respectively rotatably connected to support rods 408, and one end of the support rods 408 is fixedly connected to three first springs 409, and the support rods 408 are located inside the first springs 409 and are fixedly connected to a damper 410, and one end of the first springs 409 and the damper 410 are both fixedly connected to the receiving groove 406; In this embodiment, when the accommodating groove 406 is in a horizontal state, it is aligned with the end of the support frame 2, so that the subsequent plate can enter the accommodating groove 406 smoothly. When welding the plate, the plate is first placed on the electric roller 3 on the top of one of the support frames 2, and one side of the plate is welded. Then, the multiple electric rollers 3 are driven to rotate to transport the plate into the accommodating groove 406. During this process, the plate will enter between the two conveyor belts 407 and be transported to the accommodating groove 406 through the two conveyor belts 407. In the initial state, the distance between the two conveyor belts 407 needs to be smaller than the thickness of the plate. Therefore, when the plate enters between the two conveyor belts 407, the conveyor belts 407 will be squeezed. At this time, the first spring 409 and the damper 410 will contract. The design allows the two conveyor belts 407 to clamp the plates to prevent the plates from shaking significantly during the subsequent flipping process. The telescopic characteristics of the first spring 409 and the damper 410 allow plates of different thicknesses to enter smoothly between the two conveyor belts 407. In addition, the setting of the damper 410 can support the first spring 409 to prevent the first spring 409 from bending, and at the same time have a shock-absorbing effect, so that the conveyor belt 407 can be more stable when transporting the plates. When the plate enters the accommodating groove 406, the rotating column 403 is driven to rotate, thereby driving the plate to rotate. When the rotating column 403 rotates 180°, the plate is flipped over. At this time, the plate is transported to the electric roller 3 on the other support frame 2 through the conveyor belt 407 to facilitate the subsequent welding operation on the other side of the plate.

[0019] like Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, the transmission groove 405 is provided with a through groove 411 at one end of the accommodating groove 406, and the transmission groove 405 is communicated with the accommodating groove 406 through the through groove 411, and the transmission groove 405 is rotatably connected to the first rotating shaft 412 at one end, and the first sleeve 413 is slidably connected at both ends of the first rotating shaft 412. One end of the outer wall of the first sleeve 413 is fixedly connected to the bevel gear ring 414, and one end of the bevel gear ring 414 is meshedly connected to the first bevel gear 415, and one end of the first bevel gear 415 is fixedly connected to the second rotating shaft 416, and one end of the second rotating shaft 416 passes through the through groove 411 and is fixedly connected to the input shaft of the conveyor belt 407, and first spline grooves 417 are respectively provided at both ends of the first rotating shaft 412, and a first spline block 418 is fixedly connected to the inner wall of the first sleeve 413, and the first spline block 418 is slidably connected to the first spline groove 417; In this embodiment, when it is necessary to drive the conveyor belt 407 to rotate, it is necessary to first drive the first rotating shaft 412 to rotate. During the rotation of the first rotating shaft 412, the first sleeve 413 and the bevel gear ring 414 will be driven to rotate. During the rotation of the bevel gear ring 414, the first bevel gear 415 and the second rotating shaft 416 will be driven to rotate. When the second rotating shaft 416 rotates, the input shaft of the conveyor belt 407 will be driven to rotate, thereby driving the conveyor belt 407 to rotate. When the plate enters between the two conveyor belts 407, the conveyor belt 407 and the support rod 408 will move up and down, thereby driving the first bevel gear 415 to move up and down. Therefore, by slidingly connecting the first sleeve 413 and the first rotating shaft 412 together, the bevel gear ring 414 can be smoothly rotated. Move up and down, wherein the first sleeve 413 is rotatably connected to the support rod 408, so that the support rod 408 can synchronously drive the bevel gear ring 414 and the first bevel gear 415 to move up and down, so that the bevel gear ring 414 and the first bevel gear 415 can be stably engaged and connected together, and through the design of the first spline groove 417 and the first spline block 418, the first rotating shaft 412 can smoothly drive the first sleeve 413 and the bevel gear ring 414 to rotate, and the two bevel gear rings 414 are symmetrically arranged, so when the first rotating shaft 412 rotates, the two second rotating shafts 416 rotate in opposite directions, so that the two conveyor belts 407 rotate in opposite directions, so that the two conveyor belts 407 can smoothly transport the plates to the receiving groove 406.

[0020] like Figure 5 、 Figure 8 and Figure 10As shown, the transmission groove 405 is located adjacent to the first rotating shaft 412 and is rotatably connected to the second sleeve 419. One end of the second sleeve 419 is fixedly connected to the second bevel gear 420. The middle part of the first rotating shaft 412 is fixedly connected to the third bevel gear 421. The second bevel gear 420 is meshed with the third bevel gear 421. The inner wall of the second sleeve 419 is slidably connected to the slide rod 422. The outer wall of the slide rod 422 is provided with a second spline groove 423. The inner wall of the second sleeve 419 is fixedly connected to the second spline block 424. The second spline groove 423 is slidably connected to the second spline block 424. In this embodiment, when it is necessary to drive the first rotating shaft 412 to rotate, it is necessary to first drive the slide rod 422 to rotate. When the slide rod 422 rotates, it will drive the second sleeve 419 to rotate, thereby driving the second bevel gear 420 to rotate. When the second bevel gear 420 rotates, it will drive the third bevel gear 421 to rotate, thereby driving the first rotating shaft 412 to rotate. Through the design of the second spline groove 423 and the second spline block 424, the slide rod 422 can smoothly drive the second sleeve 419 to rotate.

[0021] like Figure 1 and Figure 5 As shown, one end of the two support frames 2 is commonly fixedly connected to a connecting rod 5, one end of the connecting rod 5 is rotatably connected to a first transmission shaft 6, one end of the first transmission shaft 6 extends to the inside of the driving groove 404, and is rotatably connected to the rotating column 403, the first transmission shaft 6 is located inside the driving groove 404 and is fixedly connected to a bevel gear 7, one end of the bevel gear 7 is meshed with four fourth bevel gears 425, one end of the fourth bevel gear 425 is fixedly connected to a second transmission shaft 426, one end of the second transmission shaft 426 extends to the inside of the transmission groove 405, and is fixedly connected to a first toothed disc 427, and one end of the sliding rod 422 is fixedly connected to a second toothed disc 428 adapted to the first toothed disc 427; In this embodiment, when it is necessary to drive the slide rod 422 to rotate, it is necessary to first drive the first transmission shaft 6 to rotate. When the first transmission shaft 6 rotates, it will drive the bevel gear 7 to rotate. When the bevel gear 7 rotates, it will drive the four fourth bevel gears 425 to rotate. When the fourth bevel gear 425 rotates, it will drive the second transmission shaft 426 and the first toothed disc 427 to rotate. When the second toothed disc 428 is meshed with the first toothed disc 427, the second toothed disc 428 will rotate with the first toothed disc 427, thereby driving the slide rod 422 to rotate. The two fourth bevel gears 425 that are simultaneously in a horizontal or vertical state are mirror-set. Therefore, when the bevel gear 7 rotates, the two fourth bevel gears 425 rotate in opposite directions, thereby making the conveyor belts 407 in the two receiving grooves 406 rotate in opposite directions. In this way, the input and output of the plate can be realized without changing the rotation direction of the first transmission shaft 6.

[0022] like Figure 2As shown, the rotating column 403 is located at both ends of the transmission groove 405 and is respectively provided with a slide groove 429, one end of the slide groove 429 is fixedly connected to the second spring 430, one end of the second spring 430 is fixedly connected to the slider 431, the slider 431 is slidably connected to the slide groove 429, one end of the two sliders 431 is commonly fixedly connected to a connecting frame 432, the connecting frame 432 is rotatably connected to the slide rod 422, one end of the connecting frame 432 is fixedly connected to a connecting plate 433, the support frame 2 is located at one end of the rotating column 403 and is rotatably connected to the extrusion wheel 8, and the extrusion wheel 8 is rollingly connected to the connecting plate 433; In this embodiment, during actual operation, only when the accommodating slot 406 is in a horizontal state, that is, aligned with one end of the support frame 2, is it necessary to drive the conveyor belt 407 inside the accommodating slot 406 to rotate. When the accommodating slot 406 is in other positions, there is no need to drive the conveyor belt 407 inside it to rotate. Therefore, the position of the second toothed disc 428 is controlled by the design of the second spring 430, the connecting plate 433 and the extrusion wheel 8. When the accommodating slot 406 is in a horizontal state, the connecting plate 433 is squeezed by the extrusion wheel 8, and thus moves toward the first toothed disc 427, thereby driving the sliding rod 422 and the second toothed disc 428 to move toward the first toothed disc 427, so that the second toothed disc 428 can engage with the first toothed disc 427. When the second transmission shaft 426 rotates, the accommodating groove 406 will gradually tilt, and the connecting plate 433 will move with the rotation of the rotating column 403. When the connecting plate 433 is disengaged from the extrusion wheel 8, the second spring 430 will rebound quickly, so that the sleeve slider 431, the connecting frame 432 and the connecting plate 433 move. When the connecting frame 432 moves, it will drive the slide bar 422 and the second gear plate 428 to move, so that the second gear plate 428 is separated from the first gear plate 427. In this way, when the second transmission shaft 426 rotates, it will not drive the slide bar 422 to rotate, thereby stopping the conveyor belt 407 from rotating.

[0023] like Figure 3 and Figure 11 As shown, the center of one end of the rotating column 403 away from the support frame 2 is fixedly connected to a groove wheel 434, one end of the support ring 402 is fixedly connected to a mounting frame 435, one end of the mounting frame 435 is rotatably connected to a third transmission shaft 436, one end of the third transmission shaft 436 is fixedly connected to a turntable 437, one end of the turntable 437 is fixedly connected to a notched disc 438, the notched disc 438 is located directly below the groove wheel 434, the turntable 437 is located at the notch of the notched disc 438 and is fixedly connected to a transmission pin 439, the side wall of the groove wheel 434 is provided with four arc grooves 440, the notched disc 438 is slidably connected to the arc groove 440, the groove wheel 434 is provided with a groove 441 between the two arc grooves 440, and the transmission pin 439 is movably connected to the groove 441; When the third transmission shaft 436 rotates, the turntable 437, the notched disc 438 and the transmission pin 439 will be driven to rotate. When the notched disc 438 contacts the arc groove 440 of the groove wheel 434, the groove wheel 434 will not rotate. When the notch of the notched disc 438 moves to the position of the groove wheel 434, the transmission pin 439 will move into the groove 441 of the groove wheel 434, thereby driving the groove wheel 434 to rotate, thereby driving the rotating column 403 to rotate. There are four grooves 441, which are the same as the number of the accommodating grooves 406. Therefore, the angle of each rotation of the groove wheel 434 is 90°, so that the angle of rotation of the rotating column 403 is 90°, so that when the rotating column 403 stops rotating, the accommodating groove 406 is either in a horizontal state or in a vertical state.

[0024] like Figure 1 and Figure 3 As shown, one end of the base 1 is fixedly connected to a motor 9, an output end of the motor 9 is fixedly connected to a drive shaft 10, the drive shaft 10 is rotatably connected to the support block 401, the drive shaft 10 and one end of the first transmission shaft 6 are fixedly connected to a first synchronous wheel 11, and the two first synchronous wheels 11 are driven by a first synchronous belt 12; the drive shaft 10 and one end of the third transmission shaft 436 are fixedly connected to a second synchronous wheel 13, and the two second synchronous wheels 13 are driven by a second synchronous belt 14; In this embodiment, the drive shaft 10 is driven to rotate by the motor 9. At this time, the first transmission shaft 6 will rotate with the drive shaft 10 under the transmission action of the first synchronous wheel 11 and the first synchronous belt 12, thereby driving the bevel gear 7, the first gear plate 427, the second gear plate 428, the slide bar 422 and the first rotating shaft 412 to rotate, thereby driving the conveyor belt 407 to rotate. In addition, under the transmission action of the second synchronous wheel 13 and the second synchronous belt 14, the third transmission shaft 436 will also rotate with the drive shaft 10, thereby driving the turntable 437, the notched disc 438, the transmission pin 439 and the groove wheel 434 to rotate. As long as the rotation speed of the drive shaft 10 is constant, regardless of the size of the plate, the time for the end of the plate to move from the opening of the receiving groove 406 to the inner wall position of the receiving groove 406 is constant, and the frequency and time of the intermittent rotation of the rotating column 403 are also constant. Therefore, in actual use, it is necessary to allow the plate to completely enter the receiving groove 406 during the period when the rotating column 403 stops rotating. It is only necessary to change the transmission speed of the conveyor belt 407. The transmission speed of the conveyor belt 407 can be adjusted by changing the size of the first bevel gear 415, the second bevel gear 420, the third bevel gear 421 and the fourth bevel gear 425.

[0025] like Figure 1 and Figure 3As shown, a U-shaped frame 15 is fixedly connected to one end of the top of the support frame 2 away from the rotating column 403, a mechanical arm 16 is provided on the top of the U-shaped frame 15, and a welding gun 17 is provided at one end of the mechanical arm 16; In this embodiment, the welding operation is performed on the plate by the design of the welding gun 17, and the angle and position of the welding gun 17 are adjusted by the design of the robot arm 16, so as to better weld the plate.

[0026] Working principle: When welding the plate, first place the plate on the electric roller 3 on the top of one of the support frames 2, and then use the robot arm 16 and the welding gun 17 to weld one side of the plate. When the welding of one side of the plate is completed, the electric roller 3 is driven to rotate, thereby conveying the plate to the receiving groove 406. During this process, the end of the plate will enter between the two conveyor belts 407. At this time, the motor 9 is turned on, and the drive shaft 10 will rotate under the drive of the motor 9. At this time, the first transmission shaft 6 will rotate with the drive shaft 10 under the transmission action of the first synchronous wheel 11 and the first synchronous belt 12. When the bevel gear 7 rotates, it drives the four fourth bevel gears 425 to rotate. When the fourth bevel gear 425 rotates, it drives the second transmission shaft 426 and the first gear plate 427 to rotate. When the accommodating groove 406 is in a horizontal state, the connecting plate 433 is squeezed by the extrusion wheel 8, so that it moves toward the first gear plate 427, thereby driving the sliding rod 422 and the second gear plate 428 to move toward the first gear plate 427, so that the second gear plate 428 can be engaged with the first gear plate 427. When the second gear plate 428 is engaged with the first gear plate 427, the second gear plate 428 is engaged with the first gear plate 427. The first gear disc 427 rotates, thereby driving the slide bar 422 to rotate. When the slide bar 422 rotates, the second sleeve 419 rotates, thereby driving the second bevel gear 420 to rotate. When the second bevel gear 420 rotates, the third bevel gear 421 rotates, thereby driving the first rotating shaft 412 to rotate. During the rotation of the first rotating shaft 412, the first sleeve 413 and the bevel gear ring 414 rotate. During the rotation of the bevel gear ring 414, the first bevel gear 415 and the second rotating shaft 416 rotate. When the second rotating shaft 416 rotates, the input shaft of the conveyor belt 407 rotates, thereby driving the conveyor belt 407 rotates, and the conveyor belt 407 can transport the plate into the receiving groove 406 when rotating. When the plate enters between the two conveyor belts 407, the conveyor belt 407 is squeezed. At this time, the first spring 409 and the damper 410 will contract. The design of the first spring 409 allows the two conveyor belts 407 to clamp the plate, preventing the plate from shaking greatly during the subsequent turning process. In addition, the setting of the damper 410 can support the first spring 409 to prevent the first spring 409 from bending, and at the same time play a shock-absorbing effect, so that the conveyor belt 407 can be more stable when transporting the plate; When the plate has completely entered the receiving groove 406, it is necessary to drive the rotating column 403 to rotate for turning over. During the rotation of the driving shaft 10, the third transmission shaft 436 will also rotate with the driving shaft 10 under the transmission action of the second synchronous wheel 13 and the second synchronous belt 14. When the third transmission shaft 436 rotates, it will drive the turntable 437, the notched disc 438 and the transmission pin 439 to rotate. When the notched disc 438 contacts the arc groove 440 of the groove wheel 434, the groove wheel 434 will not rotate at this time. When the notch of the notched disc 438 moves to the position of the groove wheel 434, the transmission pin 439 will move into the groove 441 of the groove wheel 434, thereby driving the groove wheel 434 to rotate, thereby driving the rotating column 403 to rotate. There are four grooves 441, which are the same as the number of the receiving grooves 406. Therefore, the angle of each rotation of the groove wheel 434 is 90°, from The angle of rotation of the rotating column 403 is always 90 degrees, so that when the rotating column 403 stops rotating, the receiving groove 406 is either in a horizontal state or in a vertical state. Therefore, when the rotating column 403 rotates twice, the plate is turned over. As long as the rotation speed of the drive shaft 10 is constant, the time for the end of the plate to move from the opening of the receiving groove 406 to the position of the inner wall of the receiving groove 406 is constant regardless of the size of the plate, and the frequency and time of the intermittent rotation of the rotating column 403 are also constant. Therefore, in actual use, it is necessary to allow the plate to completely enter the receiving groove 406 during the period when the rotating column 403 stops rotating. It is only necessary to change the conveying speed of the conveyor belt 407, and the conveying speed of the conveyor belt 407 can be adjusted by changing the sizes of the first bevel gear 415, the second bevel gear 420, the third bevel gear 421 and the fourth bevel gear 425. When the accommodating groove 406 is in a horizontal state, that is, aligned with one end of the support frame 2, it is necessary to drive the conveyor belt 407 inside the accommodating groove 406 to rotate. When the accommodating groove 406 is in other positions, there is no need to drive the conveyor belt 407 inside it to rotate. When the accommodating groove 406 is in a horizontal state, the connecting plate 433 is squeezed by the extrusion wheel 8, and thus it moves toward the first gear plate 427, thereby driving the sliding rod 422 and the second gear plate 428 to move toward the first gear plate 427, so that the second gear plate 428 can be meshed with the first gear plate 427, and then the second transmission shaft 426 can smoothly drive the sliding rod 422 to rotate. During this process, the second spring 430 will contract. When the rotating column 403 rotates, the accommodating groove 406 will gradually tilt, and the connecting plate 433 will move with the rotation of the rotating column 403. When the connecting plate 433 is disengaged from the extrusion wheel 8, the second spring 430 will rebound quickly, thereby When the plate is turned over, the second gear plate 428 will mesh with the first gear plate 427, so that the second transmission shaft 426 can smoothly drive the slide bar 422 to rotate, thereby driving the second sleeve 419, the second bevel gear 420, the third bevel gear 421, the first rotating shaft 412 and the second rotating shaft 416 to rotate, thereby driving the conveyor belt 407 to rotate, and the plate is transported to the electric roller 3 on the other support frame 2 through the conveyor belt 407, so that the mechanical arm 16 and the welding gun 17 at one end of the support frame 2 can perform welding operations on the other side of the plate.
