The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures are prone to corrosion. Generally, steel structures need to be derusted, galvanized or painted, and regular maintenance is required. When building and installing steel structure buildings, some steel structures need to be pre-welded and spliced on the ground. When the existing steel structure welding device for building construction is in use, it cannot effectively detect the butt joint situation of the steel structure, and there are situations of welding misalignment and uneven welding.

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] Example 1, as Figure 1-2As shown in the figure, a steel structure welding device for building construction includes an auxiliary transportation component 1. A base group 3 is fixedly connected to the lower end of the auxiliary transportation component 1. A first motor component 2 is provided at the left part of the upper side of the base group 3. Symmetrically arranged clamping mechanisms 4 are provided on the upper side of the base group 3. The output end of the first motor component 2 is connected to the clamping mechanism 4 on the left side through a belt. A transportation group 5 is provided in the middle of the base group 3. An I-beam 7 is jointly arranged between the upper side of the transportation group 5 and the two clamping mechanisms 4. A welding mechanism 6 is jointly provided between the right part of the upper side of the base group 3 and the lower right part of the transportation group 5.

[0032] It should be noted that the auxiliary transportation component 1 is composed of a fixed frame, rolling wheels and a conveyor belt, and is used for guiding and transporting the I-beam. The first motor component 2 is composed of a motor body and a pulley. The specific installation method, circuit connection method and control method of the motor body in the first motor component 2 are all conventional designs and are the conventional design means of designers.

[0033] The I-beam 7 belongs to a kind of steel structure. Before building construction, some I-beams 7 need to be additionally welded with strengthening bases (i.e., steel plates). First, one end of the I-beam 7 is lifted by an external hoisting device and placed on the auxiliary transportation component 1. The auxiliary transportation component 1 enables the I-beam 7 to be smoothly pushed between the two clamping mechanisms 4 and onto the transportation group 5. Then, an appropriate amount of steel plates are placed in the welding mechanism 6, and the I-beam 7 is clamped and fixed by the two clamping mechanisms 4. Then, the welding mechanism 6 is operated, and with the cooperation of the base group 3, the steel plates in the welding mechanism 6 are placed on the inner cavity bottom wall on one side of the I-beam 7 and welded. According to the requirements, equidistant welding is carried out from the right side to the left side of the I-beam 7. After one side is welded, with the cooperation of the base group 3, the transportation group 5 starts to extend forward and backward. After the extension is completed, the first motor component 2 is started, and with the cooperation of the belt, the two clamping mechanisms 4 drive the I-beam 7 to rotate 180 degrees, so that the welded side is turned downward, and welding of the other side is started. After the flipping is completed, with the cooperation of the base group 3, the transportation group 5 contracts and supports the lower end of the I-beam 7. Then, the welding mechanism 6 is started to carry out equidistant welding from left to right. During this process, the welding mechanism 6 can also grind and remove the welding slag on the welded side below. Finally, after the other side is welded, the transportation group 5 extends again, the first motor component 2 is started in cooperation with the belt, the clamping mechanism 4 drives the welded I-beam 7 to flip again, and the welding mechanism 6 cleans the welding slag on the other side. After all the cleaning is completed, the clamping mechanism 4 releases the clamping of the I-beam 7, and with the cooperation of the transportation group 5, it is transported out from the right side, completing the entire welding work. During the whole process, there is no need for manual welding or holding the steel plates by hand, which saves time and effort, and the welding slag can also be removed after welding.

[0034] To assist the clamping mechanism 4, the transportation group 5 and the welding mechanism 6 to complete the welding work of the I-beam 7, as Figure 3As shown in the figure, the base group 3 includes a base body 31. On the upper end of the base body 31, there are symmetrically arranged first slide rails 35 in the front and rear. In the middle of the upper end of the base body 31, there are two symmetrically arranged second slide rails 37 on the left and right. On the left rear part of the upper end of the base body 31, there is an installation groove 32. A rotating shaft 34 is rotatably connected to the inner cavity of the installation groove 32. A first transmission wheel 33 is fixedly connected to the left end of the rotating shaft 34. A second transmission wheel 36 is fixedly connected to the right end of the rotating shaft 34. The left side of the upper end of the base body 31 is fixedly connected to the lower end of the auxiliary transportation component 1. The left rear part of the upper end of the base body 31 is fixedly connected to the lower end of the first motor component 2. The outer surface of the first transmission wheel 33 is connected to the output end of the first motor component 2 through a belt.

[0035] First, the first transmission wheel 33 is composed of two second transmission wheels 36, and the first transmission wheel 33 is adapted to the belt pulley in the first motor component 2 and is connected by a belt. The first slide rails 35 are fixedly installed on the front and rear sides of the upper end of the base body 31, so that the welding mechanism 6 can slide left and right on the first slide rails 35. Two second slide rails 37 are fixedly installed on the left and right sides of the upper end of the base body 31, so that the transportation group 5 can be extended or contracted back and forth on the four second slide rails 37. By starting the first motor component 2 and using the belt in cooperation, the first transmission wheel 33 drives the rotating shaft 34 to rotate in the inner cavity of the installation groove 32, and then drives the second transmission wheel 36 to rotate. Because the first transmission wheel 33 and the second transmission wheel 36 rotate simultaneously, and with the cooperation of the belt, the clamping mechanisms 4 on the left and right sides are driven to operate, driving the I-beam 7 to rotate 180 degrees. Through the mutual cooperation of the clamping mechanism 4, the transportation group 5 and the welding mechanism 6, the welding work of the I-beam 7 is finally completed.

[0036] Embodiment 2. In order to achieve the purpose of clamping and flipping the I-beam 7, as Figure 4 shown, both of the two clamping mechanisms 4 include limit brackets 41. A clamping group 42 is rotatably connected to the inner cavity of each of the two limit brackets 41. On the lower part of the rear side of the outer surface of each of the two limit brackets 41, there is a fixedly connected mounting bracket 44. A first gear 45 is rotatably connected to the inner cavity of each of the two mounting brackets 44. A third transmission wheel 43 is fixedly connected to one end of each of the two first gears 45 away from each other. The outer surfaces of the two first gears 45 are respectively meshed with the two clamping groups 42. The lower ends of the two limit brackets 41 are respectively fixedly connected to the left and right sides of the upper end of the base body 31. The outer surface of the third transmission wheel 43 on the left side is connected to the first transmission wheel 33 through a belt. The outer surface of the third transmission wheel 43 on the right side is connected to the second transmission wheel 36 through a belt.

[0037] First, one end of the I-beam 7 is lifted by an external hoisting device and placed on the auxiliary transportation component 1. Through the auxiliary transportation component 1, the I-beam 7 can be smoothly pushed between the two clamping mechanisms 4 and onto the transportation group 5. Then, the clamping groups 42 on the left and right sides clamp and fix the I-beam 7. With the cooperation of the base group 3, the welding mechanism 6, and the transportation group 5, the welding work on one side of the I-beam 7 is completed. When welding on the other side is required, the first motor component 2 is started. With the cooperation of the belt, the first driving wheel 33 drives the rotating shaft 34 to rotate in the inner cavity of the installation groove 32, thereby driving the second driving wheel 36 to rotate. As a result, the first driving wheel 33 and the second driving wheel 36 rotate simultaneously. With the cooperation of the belt, the driving wheels 43 on the left and right sides are driven to rotate. Through the rotation of the driving wheels 43, the first gears 45 on the left and right sides rotate in the inner cavities of the two mounting frames 44 respectively, and drive the clamping groups 42 to rotate 180 degrees in the inner cavity of the limiting support 41, completing the flipping of the I-beam 7. Ultimately, the purpose of clamping and flipping the I-beam 7 is achieved.

[0038] Further illustration, as shown in the transportation group 5, the two clamping groups 42 both include rotating gear rings 421. On the inner surfaces of the two rotating gear rings 421, there are symmetrically arranged hydraulic cylinders 422 up and down. The output ends of the two hydraulic cylinders 422 on the same side are fixedly connected with clamping blocks 423. The mutually approaching sides of the outer surfaces of the two clamping blocks 423 on the same side are respectively in contact with the upper and lower sides of the outer surface of the I-beam 7 on the same side. The outer surfaces of the two rotating gear rings 421 are respectively rotatably connected to the inner cavities of the two limiting supports 41, and the outer surfaces of the two rotating gear rings 421 are respectively meshed with the outer surfaces of the two first gears 45.

[0039] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 422 in the present invention are all conventional designs and are the conventional design means of designers.

[0040] When the I-beam 7 is transported to the middle of the two rotating gear rings 421, by simultaneously starting the four hydraulic cylinders 422, the two clamping blocks 423 on the same side are driven to move closer to each other to a suitable position, so that the two clamping blocks 423 on the left and right sides respectively clamp the left and right sides of the I-beam 7, completing the clamping and fixing of the I-beam 7 and making the I-beam 7 immovable. When the I-beam 7 needs to be flipped 180 degrees, through the rotation of the first gears 45 on the left and right sides, the rotating gear rings 421 on the left and right sides are simultaneously driven to rotate 180 degrees in the inner cavity of the limiting support 41, completing the clamping, fixing, and placement operations of the I-beam 7.

[0041] Example 3, based on Example 1 and Example 2, this example assists the welding mechanism 6 to complete the welding work of the I-beam 7, as Figure 6 and Figure 7As shown in the figure, the transportation group 5 includes side support plates 51 that are symmetrical front and back and protective shells 591 that are symmetrical left and right. At the lower sides of the ends of the two side support plates 51 that are away from each other, there are two sliding sleeves 52 that are symmetrical left and right. At the upper parts of the sides of the two side support plates 51 that are close to each other, there are several rollers 55. The movements of the several rollers 55 on the front and back sides away from each other all penetrate the side support plate 51 on the same side and are fixedly connected to a second gear 56. The outer surfaces of the several second gears 56 on the same side are connected by a chain. At the lower sides of the rear ends of the two side support plates 51, there is a first motor 59. The output ends of the two first motors 59 and the ends of the second gears 56 at the rightmost parts of the front and back sides away from each other are fixedly connected to a fourth transmission wheel 58. The two fourth transmission wheels 58 on the same side are connected by a belt. At the lower sides of the ends of the two side support plates 51 that are close to each other, there are toothed plates 593 that are symmetrical left and right. The outer surfaces of the two toothed plates 593 on the same side are jointly meshed and connected to a third gear 592. The inner cavities of the two third gears 592 are respectively rotationally connected to the two third gears 592. The lower ends of the two protective shells 591 are respectively fixedly connected to the left and right sides of the upper end of the base body 31. At the middle lower side of the rear end of the front side support plate 51, there is a second hydraulic cylinder 57 fixedly connected. The lower end of the second hydraulic cylinder 57 is fixedly connected to the middle of the upper end of the base body 31. At the lower sides of the ends of the two side support plates 51 that are close to each other, there are rectangular through grooves 53. At the middle parts of the ends of the two side support plates 51 that are close to each other, there are sliding grooves 54. The inner cavities of the four sliding sleeves 52 on the front side are respectively slidably connected to the front sides of the outer surfaces of the four second slide rails 37. The inner cavities of the four sliding sleeves 52 on the rear side are respectively slidably connected to the rear sides of the outer surfaces of the four second slide rails 37.

[0042] It should be noted that the specific installation methods, connection methods of the circuit, and control methods of the second hydraulic cylinder 57 and the first motor 59 in the present invention are all conventional designs and are the conventional design means of designers.

[0043] First, the I-beam 7 is clamped and fixed by two clamping groups 42. The front and rear sides of the lower end of the I-beam 7 are respectively attached to the upper sides of the outer surfaces of a number of rollers 55 on the front and rear sides. The connecting plate 61 in the welding mechanism 6 passes through the inner cavities of the rectangular through grooves 53 on the front and rear sides to connect the drive seats 62 on the front and rear sides. Chutes 54 are opened on the side support plates 51 on the front and rear sides for installing and slidingly connecting the grinding group 64. When the I-beam 7 needs to be flipped, first start the second hydraulic cylinder 57, so that the second hydraulic cylinder 57 drives the front side support plate 51 located on the front side to move forward on the outer surface of the slide rail two 37 in cooperation with the sliding sleeve 52. At the same time, it drives the toothed plate 593 fixed on the front side support plate 51 to slide forward on the outer surface of the gear three 592 in the protective shell 591, driving the gear three 592 to rotate in the protective shell 591. Then it drives the toothed plate 593 installed on the upper side of the rear side support plate 51 to slide backward, pushing the rear side support plate 51 to slide backward on the outer surface of the slide rail two 37 in cooperation with the sliding sleeve 52, so that the front and rear side support plates 51 move away from each other to complete the extension, making the front and rear side support plates 51 not affect the flipping of the I-beam 7. While the front and rear side support plates 51 move away from each other, under the cooperation of the chute 54, it drives the grinding group 64 to contract downward, so that the grinding group 64 also does not affect the flipping of the I-beam 7. At this time, the flipping operation of the I-beam 7 is completed through the clamping mechanism 4 in cooperation with the first motor component 2, the base group 3 and the belt. After the flipping is completed, start the second hydraulic cylinder 57. Under the cooperation and adaptation of the sliding sleeve 52, the gear three 592 and the toothed plate 593, the two side support plates 51 move closer to each other to return to the initial position, and at the same time drive the grinding group 64 to extend upward to restore the initial height, finally realizing the work of assisting the welding mechanism 6 to complete the welding of the I-beam 7. In addition, after the welding and slag removal of the I-beam 7 are completed, the clamping of the I-beam 7 by the clamping group 42 is released, and the front and rear first motors 59 are started. Under the combined use of the belt, the fourth transmission wheel 58 and the chain, a number of second gears 56 on the front and rear sides rotate simultaneously, and then drive a number of same-side rollers 55 to rotate. Through the rotation of a number of rollers 55 on the front and rear sides, the I-beam 7 is driven to be transported to the right side, and with the cooperation of external feeding equipment, the operation of transporting the I-beam 7 out of the device is completed.

[0044] For the purpose of realizing the welding and slag removal of 7, as Figure 8 and Figure 9As shown in the figure, the welding mechanism 6 includes a connecting plate 61. The front and rear sides of the outer surface of the connecting plate 61 respectively penetrate through the inner cavities of two rectangular through slots 53. The middle part of the upper end of the connecting plate 61 is fixedly connected with a grinding group 64. Both the front and rear ends of the connecting plate 61 are fixedly connected with driving seats 62. The upper end of the driving seat 62 located at the rear side is fixedly connected with a welding robot arm 63. The upper end of the driving seat 62 located at the front side is fixedly connected with a feeding table 68. The middle part of the left side of the lower end of the feeding table 68 is fixedly connected with a motor component two 69. The middle part of the inner cavity bottom wall of the feeding table 68 is provided with a rotating component one 691. The output end of the motor component two 69 is connected with the left side of the outer surface of the rotating component one 691 through a belt. The outer surface of the rotating component one 691 is meshed with symmetrically arranged pushing plates 67 on the left and right. The rear side of the upper end of the feeding table 68 is fixedly connected with a mechanical clamping arm 65. The middle part of the upper end of the feeding table 68 is fixedly connected with an L-shaped plate 66. And the rear side of the L-shaped plate 66 is located directly below the mechanical clamping arm 65. The inner cavity of the L-shaped plate 66 is rotatably connected with a rotating component two 695. The front side of the inner cavity of the L-shaped plate 66 and the front side of the outer surface of the rotating component two 695 are jointly provided with a threaded sliding seat 694. The inner cavity of the threaded sliding seat 694 is rotatably connected with an elastic rotating piece 693. The middle part of the front side of the inner cavity bottom wall of the feeding table 68 is fixedly connected with a motor component three 692. The output end of the motor component three 692 is connected with the front side of the outer surface of the rotating component two 695 through a belt. The inner cavities of the two driving seats 62 are respectively slidably connected with the outer surfaces of two slide rails one 35.

[0045] It should be noted that the driving seat 62 is composed of a base, a driving motor, a controller, a sensor, a reducer, a chain and other components, which cooperate with each other, enabling the driving seat 62 to move left and right on the first slide rail 35. The second motor component 69 and the third motor component 692 are both composed of a small motor and a pulley. In the present invention, the specific installation methods and ways of the small motors in the welding robot arm 63, the mechanical clamping arm 65, the second motor component 69 and the third motor component 692, as well as the connection methods of the circuits and the control methods of the driving motor, the controller, the sensor and the reducer in the driving seat 62 are all conventional designs and are the conventional design means of designers. The welding robot arm 63 is composed of a base, joints, an arm, a wrist, a welding torch, a wire feeding mechanism, a control system and a sensor system. Each part cooperates with each other to jointly achieve automated and intelligent welding operations, with high efficiency and accuracy. In addition, the first rotating component 691 is composed of a long rod, a pulley and reciprocating thread grooves symmetrically arranged on the left and right sides of the outer surface of the long rod. The second rotating component 695 is composed of a reciprocating threaded rod and a pulley. The pulley in the first rotating component 691 is connected to the pulley in the second motor component 69 through a belt, and the pulley in the third motor component 692 is connected to the pulley in the second rotating component 695 through a belt. A groove for installing the first rotating component 691 is provided in the middle of the inner bottom wall of the feeding table 68. When the first rotating component 691 rotates, it can drive the pushing plates 67 on the left and right sides to reciprocate left and right in the inner cavity of the groove. The mechanical clamping arm 65 is composed of a base, a horizontal hydraulic telescopic rod, a vertical hydraulic telescopic rod and hydraulic claws, which is a conventional design and is the conventional design means of designers, and can complete the grasping of steel plates.

[0046] First, place an appropriate amount of steel plates into the inner cavity of the feeding table 68 and clamp them between two pushing plates 67. When the two clamping groups 42 clamp and fix the I-beam 7 onto the transportation group 5, start the third motor component 692. With the cooperation of the belt, the second rotating component 695 rotates within the inner cavity of the L-shaped plate 66. Through the rotation of the second rotating component 695, the threaded sliding seat 694 slides backward within the inner cavity of the L-shaped plate 66, thereby driving the elastic rotating piece 693 to push the front end of the steel plate located in the middle of the inner cavity of the feeding table 68, causing the steel plate to move backward within the inner cavity of the feeding table 68 to the lower side of the mechanical clamping arm 65. The mechanical clamping arm 65 clamps the steel plate and places the steel plate at a suitable position on the bottom wall of the inner cavity of the I-beam 7. Then, weld the connection between the steel plate and the I-beam 7 through the welding robotic arm 63. While the mechanical clamping arm 65 clamps the steel plate, start the second motor component 69. With the cooperation of the belt, the first rotating component 691 rotates, driving the pushing plates 67 on both the left and right sides to push the steel plates within the inner cavity of the feeding table 68 to move closer to each other to a suitable position. Moreover, the second rotating component 695 then rotates. The threaded sliding seat 694 drives the elastic rotating piece 693 to move forward and touch the elastic rotating piece 693 of the middle steel plate at this time. The elastic rotating piece 693 rotates backward within the inner cavity of the threaded sliding seat 694 and slides forward along the upper end of the steel plate. When reaching the frontmost position, the elastic rotating piece 693 rotates forward and is perpendicular to the threaded sliding seat 694, and the elastic rotating piece 693 returns to its initial position, waiting to push the middle steel plate to the lower side of the mechanical clamping arm 65 next time. When completing one welding operation, the two driving seats 62 move to the left to a suitable distance on the outer surfaces of the front and rear first slide rails 35 respectively. At the same time, the connecting plate 61 drives the grinding group 64 to move to the left within the inner cavity of the sliding groove 54 under the cooperation of the rectangular through groove 53. This cycle continues until the welding operation on one side of the I-beam 7 is completed. Then, through the first motor component 2, the base group 3, and the belt, the I-beam 7 is flipped. Before the I-beam 7 is flipped, the grinding group 64 contracts downward through the transportation group 5 so that the height of the grinding group 64 does not affect the flipping of the I-beam 7. After the flipping is completed, through the same operation, the mechanical clamping arm 65 places the steel plate at a suitable position on the I-beam 7 and welding is performed through the welding robotic arm 63. In addition, by starting the grinding group 64, the welding slag at the lower welding part of the I-beam 7 can be ground and removed, ultimately achieving the purpose of welding the I-beam 7 and removing the welding slag. Through the welding mechanism 6, not only the automatic feeding of the steel plate for welding is realized, but also the welding slag can be removed. There is no need for the staff to hold the steel plate by hand for welding, and the welding slag at the welding part does not need to be manually processed either.

[0047] Further explanation, such as Figure 10As shown, the grinding group 64 includes a telescopic support rod 641. On both the front and rear sides of the outer surface of the telescopic support rod 641, auxiliary support rods 642 are fixedly connected. The upper end of the telescopic support rod 641 and the upper ends of the two auxiliary support rods 642 are jointly fixedly connected to a bottom plate 648. On both the front and rear sides of the lower end of the bottom plate 648, connecting rods 644 are rotatably connected. On the side where the two connecting rods 644 are away from each other, sliders 643 are rotatably connected. The outer surfaces of the two sliders 643 are respectively slidably connected to the inner cavities of the two chutes 54. In the middle of the inner cavity of the bottom plate 648, a third rotating component 649 is rotatably connected. A sliding seat 646 is jointly provided on the front side of the inner cavity of the bottom plate 648 and the front side of the outer surface of the third rotating component 649. On the upper end of the sliding seat 646, grinding components 647 are symmetrically arranged left and right. On the front side of the lower end of the bottom plate 648, a fourth motor component 645 is fixedly connected. The output end of the fourth motor component 645 is connected to the front side of the outer surface of the third rotating component 649 through a belt.

[0048] It should be noted that the fourth motor component 645 is composed of a small motor and a pulley. The third rotating component 649 is composed of a reciprocating threaded rod and a pulley. And the pulley in the fourth motor component 645 is connected to the pulley in the third rotating component 649 through a belt. The grinding component 647 is composed of a grinding wheel, a housing, and a motor, and they cooperate with each other to enable the grinding component 647 to grind and remove the welding slag at the welding joint. In the present invention, the specific installation methods, connection methods of the circuits, and control methods of the small motors in the fourth motor component 645, the third rotating component 649, and the motor in the grinding component 647 are all conventional designs and are the conventional design means of designers.

[0049] Specifically, when the I-beam 7 is flipped, the side support plates 51 on the front and rear sides move away from each other. The sliding blocks 643 on the same side are driven by the sliding grooves 54 on the front and rear sides to move away from each other. The connecting rods 644 on the front and rear sides are pulled by the separation of the two sliding blocks 643, so that the connecting rods 644 on the front and rear sides drive the bottom plate 648 to compress the telescopic support rod 641 and the auxiliary support rod 642 downward to a proper position, so that when the clamping group 42 drives the I-beam 7 to flip, it will not touch the grinding component 647, and the flipping of the I-beam 7 is not affected. After the flipping is completed, the side support plates 51 on the front and rear sides move closer to each other. With the cooperation of the sliding groove 54 and the sliding block 643, the connecting rod 644 and the telescopic support rod 641, and the auxiliary support rod 642, the bottom plate 648 moves upward to restore its initial position. Then, the steel plate is clamped by the mechanical clamping arm 65 and placed at a proper position on the I-beam 7, and welding is performed by the welding robotic arm 63. Moreover, the bottom plate 648 is located at the position of the steel plate welded below. By starting the motor component four 645 and cooperating with the belt, the rotating component three 649 rotates, driving the sliding seat 646 to slide back and forth in the inner cavity of the bottom plate 648, thereby driving the two grinding components 647 to grind and remove the welding slag at the welding joints on both sides of the steel plate. After the welding at one place of the welding robotic arm 63 is completed and the lower grinding component 647 finishes grinding, when the steel plate is loaded and welded and the lower welding slag is ground and removed, through the cooperation of the hydraulic cylinder two 57 with the gear three 592, the gear three 592, the toothed plate 593, the side support plate 51 and the sliding groove 54, the sliding block 643 and the connecting rod 644 drive the bottom plate 648 to compress the telescopic support rod 641 and the auxiliary support rod 642, so that the two grinding components 647 move downward to disengage from the steel plate whose welding slag has been ground and removed. By cooperating the driving seat 62 with the connecting plate 61, the grinding group 64, the feeding table 68 and the telescopic support rod 641 move equidistantly according to requirements. During the movement, the sliding blocks 643 on the front and rear sides slide in the inner cavities of the two grinding groups 64 respectively. After moving to a proper position, the side support plates 51 on the front and rear sides move closer to each other. With the cooperation of the sliding groove 54, the sliding block 643 and the connecting rod 644, the bottom plate 648 moves upward, and at the same time, the two grinding components 647 are clamped on both sides of the next steel plate whose welding slag has not been removed, and grinding and removal and upper-side steel plate welding operations are performed, completing the automatic feeding of the steel plate and welding while also removing the welding slag at the welding joints.
