[0042] By means of the set welding table 1, when welding the bracket, the operator can first adjust the fixing component, limit and fix the welding table 1 and the fixing component, and then use the clamping component to fix the horizontal steel pipe 37 and the vertical steel pipe 37 to the welding table 1 respectively, and use the welding machine to weld the frame 36 and the steel pipe 37. After the front welding is completed, the rotating component can be used to flip the fixing component, the frame 36 and the steel pipe 37 that is partially welded to the frame 36. After the flipping is completed, the steel pipe 37 and the frame 36 that need to be welded are fully welded. When the bracket is large in size, only one welding worker is needed to complete the flipping of the bracket, which reduces the difficulty of operation and improves work efficiency. In addition, when the frame 36 and the steel pipe 37 are welded, the set clamping component can ensure the accuracy of the position of multiple steel pipes 37, and there is no need for the welding worker to hold the steel pipe 37 during welding, which further improves the convenience of operation.

The inner wall of the limiting plate 16 abuts against the bottom of the fixing plate 17. The limiting plate 16 is an elastic structure. A second fixing sleeve 18 is fixedly connected to the top of the fixing plate 17, and a pulling handle is fixedly connected to one side of the second fixing sleeve 18. A pair of first fixing sleeves 14 and a pair of second fixing sleeves 18 are both abutted against the outer wall of the frame 36. A plurality of limiting grooves 19 are provided at one end of the connecting plate 7 where the rotating shaft of the first rotating gear 8 extends out, wherein a telescopic rod 20 is fixedly connected to one side of one connecting plate 7, and a clamping rod 21 is fixedly connected to one end of the telescopic rod 20, and a limiting block 22 is fixedly connected to one side of the clamping rod 21. The limiting block 22 is clamped with the limiting groove 19, and the clamping rod 21 is coaxially arranged with the second limiting hole 5, and a circular groove is provided at the bottom of the clamping rod 21.

[0044] By setting the first rotating gear 8 and the second rotating gear 11, during operation, the welding worker can adjust the width between the pair of fixing frames 10 according to the size of the frame 36. In the initial state, one end of the clamping rod 21 and the limit block 22 fixedly connected to one side of the clamping rod 21 are clamped with the limit groove 19, so that the first rotating gear 8 cannot rotate. The operator needs to pull the circular groove at the bottom of the clamping rod 21 to drive the limit block 22 fixedly connected to one end of the clamping rod 21 and one side of the clamping rod 21 to leave the limit groove 19. At this time, the telescopic rod 20 is in a stretched state, and one end of the clamping rod 21 After the first rotating gear 8 is inserted into the second limiting hole 5 and engaged with the second limiting hole 5, and the first rotating gear 8 is not constrained by the engaging rod 21 and the limiting block 22, the welding worker can pull the pull block 13 fixedly connected to one side of the inner wall of the fixing frame 10, so that the first serrated plate 9 connected to the fixing frame 10 moves laterally, which can drive the first rotating gear 8 to rotate, and the first rotating gear 8 is meshed with the second rotating gear 11, and the second serrated plate 34 is driven to move laterally under the rotation of the second rotating gear 11, so that a pair of fixing frames 10 move synchronously in opposite directions, which is convenient for adjusting the distance between a pair of first fixing sleeves 14 After adjusting the width between the fixing frames 10 according to the size of the frame 36, the operator can place the frame 36 on the fixing frame 10 so that the side edges of the frame 36 are respectively in contact with the pair of first fixing sleeves 14, so that the pair of first fixing sleeves 14 can effectively limit the two sides of one side of the frame 36. At this time, the operator can move the second fixing sleeve 18 according to the length of the frame 36. When moving the second fixing sleeve 18, the pulling handle provided on one side of the second fixing sleeve 18 can be pulled for easy operation. The operator can move the second fixing sleeve 18 so that the second fixing sleeve 18 is in contact with the two sides of the other side of the frame 36. Effective limiting, the bottom of the second fixing sleeve 18 is fixedly connected with a fixing plate 17, the fixing plate 17 can slide in the fixing hole 38, and the fixing plate 17 is inserted into the space formed by the limiting plate 16 and the inner wall of the fixing frame 10, the limiting plate 16 is an elastic structure, the inner wall of the limiting plate 16 abuts against the bottom of the fixing plate 17, and the abutment force of the limiting plate 16 on the fixing plate 17 enables the second fixing sleeve 18 to maintain a certain stability when limiting the frame 36. The set fixing assembly can be applicable to frames 36 of different sizes, which improves the application range of the welding device, and only requires one person to operate, reducing the difficulty of operation.

[0045] like Figure 1 , Figure 4 and Figure 6 As shown, the rotating assembly includes a rotating handle 3 fixedly connected to the rotating shaft 2, a pair of slots 6 are provided on the rotating handle 3, the slots 6 are engaged with the clamping blocks 35, the clamping blocks 35 are arc-shaped, and the clamping blocks 35 are adapted to the slots 6, a first limiting hole 4 is provided on the rotating handle 3, and the first limiting hole 4 and the second limiting hole 5 are coaxially provided.

[0046] By means of the rotating assembly, the clamping rod 21 is coaxially arranged with the second limiting hole 5, and the second limiting hole 5 and the first limiting hole 4 are coaxially opened. When it is necessary to adjust the width between a pair of fixing frames 10, the operator pulls the circular groove opened at the bottom of the clamping rod 21, driving one end of the clamping rod 21 and the limiting block 22 fixedly connected to one side of the clamping rod 21 to leave the limiting groove 19. At this time, one end of the clamping rod 21 is located in the second limiting hole 5 and is clamped with the second limiting hole 5. Before restoring the clamping rod 21 and the limiting block 22 to their original positions, when the operator accidentally turns the rotating handle 3, due to One end of the clamping rod 21 is clamped with the second limiting hole 5, and the operator cannot turn the rotating handle 3 to drive the fixed component to rotate, avoiding the problem that the fixed component rotates without fixing the limiting frame 36 and the frame 36 may fall and be damaged. The set clamping block 35 has an arc structure, and the clamping block 35 is adapted to the clamping groove 6, so that when rotating the rotating handle 3, the operator needs to use a certain amount of force to rotate the rotating handle 3 to separate the clamping groove 6 from the clamping block 35, which further reduces the possibility of misoperation and improves the safety of using the welding device.

[0047] like Figure 2 , Figures 9 to 11 As shown, the inner wall of the fixing hole 38 is clamped with a clamping plate 23, the top of the clamping plate 23 is fixedly connected with a first limiting clamp 24, the first limiting clamp 24 is clamped with a frame 36, one side of the first limiting clamp 24 is fixedly connected with a first connecting rod 25, the first connecting rod 25 is fixedly connected with a pull plate 33, the pull plate 33 is an outwardly convex arc structure, the top of the first connecting rod 25 is fixedly connected with a second limiting clamp 26, the second limiting clamp 26 is clamped with a vertical steel pipe 37, the top of the second limiting clamp 26 is fixedly connected with a second connecting rod 27, both sides of the second connecting rod 27 are fixedly connected with blocks 28. The top of the second connecting rod 27 is rotatably connected to a limiting shaft 29. Both ends of the limiting shaft 29 are fixedly connected with a pair of shift rods 30. The limiting shaft 29 is fixedly connected with a third connecting rod 31. One side of the third connecting rod 31 is fixedly connected with a third limiting clamp 32. The third limiting clamp 32 is clamped with a transverse steel pipe 37. One end of the first limiting clamp 24 is an outwardly flared arc structure. The first limiting clamp 24 is an elastic structure. The second limiting clamp 26 includes a rectangular plate. Both sides of the rectangular plate are fixedly connected with S-shaped plates. The S-shaped plates are elastic structures. The third limiting clamp 32 has the same structure as the second limiting clamp 26.

[0048] By using the first limiting clamp 24, the second limiting clamp 26 and the third limiting clamp 32 in cooperation, when welding the vertical steel pipe 37 that is attached to the side of the frame 36 at the top of the fixing frame 10, the operator can insert the clamping plate 23 into the fixing hole 38. One side of the top of the fixing frame 10 is an arc-shaped structure, and the fixing hole 38 is opened on the arc-shaped structure. When the clamping plate 23 is inserted into the fixing hole 38, one end of the clamping plate 23 is inserted into the fixing hole 38 along the arc structure. The first limiting clamp 24 is clamped with the frame 36. At this time, the second limiting clamp 26 can be clamped with the vertical steel pipe 37 so that the vertical steel pipe 37 fits the side wall of the frame 36. At the same time, the steel pipe 37 that needs to be horizontally welded is clamped with the third limiting clamp 32, so as to achieve the effect of limiting and fixing the vertical steel pipe 37 and the horizontal steel pipe 37 that fit the side of the frame 36 located at the top of the fixing frame 10 during welding, and the frame 36 and the steel pipe 37 can be welded without the operator holding the steel pipe 37 by hand.

[0049] When welding the vertical steel pipes 37 on the other two sides of the frame 36, the operator can insert the clamping plate 23 into the bottom of the frame 36 so that the clamping plate 23 fits with the bottom of the frame 36, and the first limiting clamp 24 is clamped with the frame 36. By repeating the above operation, the vertical steel pipes 37 and the horizontal steel pipes 37 on the other two sides of the frame 36 can be limited and fixed during welding, thereby improving the convenience of the welding operation.

[0050] When welding the middle transverse steel pipe 37, the operator bends the third connecting rod 31 and the second connecting rod 27 so that the third connecting rod 31 and the second connecting rod 27 change from a vertical state to a horizontal state. Fig.10 As shown, when the limiting shaft 29 is rotated, the stopper 28 provided on the second connecting rod 27 abuts against a pair of shift rods 30 provided on the limiting shaft 29, so as to limit the rotation of the limiting shaft 29, so that the third connecting rod 31 and the second connecting rod 27 can only be switched between the vertical state and the horizontal state, so that the efficiency is higher when the third connecting rod 31 and the second connecting rod 27 are switched. The operator can clamp the second limiting clamp 26 and the third limiting clamp 32 with the two horizontal steel pipes 37 respectively, as shown in FIG. Fig. 9 As shown, the two shorter transverse steel pipes 37 can be neatly fixed on both sides of the longer steel pipe 37 and be on the same horizontal line, which effectively reduces the welding error.

[0051] In summary, by setting up the clamping assembly, when welding the frame 36 and the steel pipe 37, the clamping assembly can change different states to adapt to the frames 36 and steel pipes 37 at different positions, thereby improving the application range and assembly performance of the clamping assembly, and enabling multiple steel pipes 37 to maintain a certain height level, reducing welding errors, and the first limit clamp 24, the second limit clamp 26 and the third limit clamp 32 are all elastic structures, which have a better adaptation effect with the frame 36 and the steel pipe 37.

[0052] After the front sides of the frame 36 and the steel pipe 37 are welded, the operator can press the clamping rod 21 to restore the clamping rod 21 and the telescopic rod 20 to their original positions, and the clamping rod 21 and the limit block 22 are clamped with the limit groove 19, so that the second limit hole 5 is no longer clamped with one end of the clamping rod 21, and at the same time, the first rotating gear 8 cannot rotate under the limiting action of the clamping rod 21 and the limit block 22. At this time, the operator can rotate the rotating handle 3 so that the steel pipe 37 and the frame 36 welded on one side are rotated 180 degrees synchronously with the fixed component until the clamping groove 6 opened on the rotating handle 3 is clamped with the other clamping block 35. The operator can fully weld the frame 36 and the steel pipe 37 on the other side. When the volume of the bracket is large, only one welding worker is needed to complete the flipping of the bracket, which reduces the difficulty of operation and improves work efficiency.

[0053] like Figure 4 and Figure 7 As shown, the side walls of the first fixing sleeve 14 and the second fixing sleeve 18 are fixedly connected with a plurality of abutment blocks 15 . The abutment blocks 15 are in an S-shaped elastic structure, and the abutment blocks 15 abut against the outer wall of the frame 36 .

[0054] By setting the abutment blocks 15, multiple abutment blocks 15 are in an S-shaped elastic structure, and the abutment blocks 15 abut against the outer wall of the frame 36. When the first fixing sleeve 14 and the second fixing sleeve 18 are used to fix and limit the outer wall of the frame 36, the set abutment blocks 15 can fill the gap between the inner walls of the first fixing sleeve 14 and the second fixing sleeve 18 and the side walls of the frame 36, further improving the stability of the first fixing sleeve 14 and the second fixing sleeve 18 in fixing and limiting the frame 36.

[0055] The working principle of the technical solution provided by the present invention is as follows:

[0056] When in use, the welding worker can adjust the width between a pair of fixing frames 10 according to the size of the frame 36. In the initial state, one end of the clamping rod 21 and the limit block 22 fixedly connected to one side of the clamping rod 21 are clamped with the limit groove 19, so that the first rotating gear 8 cannot rotate. The operator needs to first pull the circular groove opened at the bottom of the clamping rod 21 to drive one end of the clamping rod 21 and the limit block 22 fixedly connected to one side of the clamping rod 21 to leave the limit groove 19. At this time, the telescopic rod 20 is in a stretched state, and one end of the clamping rod 21 extends into the second limit hole 5 and is clamped with the second limit hole 5. After the first rotating gear 8 is no longer constrained by the clamping rod 21 and the limit block 22, the welding worker can pull the pull block 13 fixedly connected to one side of the inner wall of the fixing frame 10, so that the first sawtooth connected to the fixing frame 10 The plate 9 moves laterally, which can drive the first rotating gear 8 to rotate. The first rotating gear 8 is meshed with the second rotating gear 11. Under the rotation of the second rotating gear 11, the second serrated plate 34 is driven to move laterally, so that a pair of fixed frames 10 move synchronously in opposite directions, which is convenient for adjusting the distance between the pair of first fixed sleeves 14. After adjusting the width between the fixed frames 10 according to the size of the frame 36, the operator can place the frame 36 on the fixed frame 10 so that the side edges of the frame 36 are respectively in contact with the pair of first fixed sleeves 14. At this time, the operator can move the second fixed sleeve 18 according to the length of the frame 36. When moving the second fixed sleeve 18, the pulling handle set on one side of the second fixed sleeve 18 can be pulled to effectively limit the second fixed sleeve 18 and the two sides of the other side of the frame 36.

[0057] At this time, when welding the vertical steel pipe 37 that is in contact with the side of the frame 36 located at the top of the fixing frame 10, the operator can insert the clamping plate 23 into the fixing hole 38, and the first limiting clamp 24 is clamped with the frame 36. The second limiting clamp 26 can be clamped with the vertical steel pipe 37 so that the vertical steel pipe 37 is in contact with the side wall of the frame 36. At the same time, the steel pipe 37 that needs to be horizontally welded is clamped with the third limiting clamp 32. When welding the vertical steel pipes 37 on the other two sides of the frame 36, the operator can insert the clamping plate 23 into the bottom of the frame 36 so that the clamping plate 23 is in contact with the bottom of the frame 36, and the first limiting clamp 24 is clamped with the frame 36. The above operation is repeated. When welding the middle horizontal steel pipe 37, the operator bends the third connecting rod 31 and the second connecting rod 27 so that the third connecting rod 31 and the second connecting rod 27 are changed from a vertical state to a horizontal state. Fig.10 As shown, the operator can clamp the second limiting clamp 26 and the third limiting clamp 32 to the two transverse steel pipes 37 respectively, as shown in FIG. Fig. 9 As shown, the two shorter transverse steel pipes 37 can be neatly fixed on both sides of the longer steel pipe 37 and on the same horizontal line, and the operator can perform front welding on the frame 36 and the steel pipe 37.

[0058] After the front sides of the frame 36 and the steel pipe 37 are welded, the operator can press the clamping rod 21 to restore the clamping rod 21 and the telescopic rod 20 to their original positions, and the clamping rod 21 and the limit block 22 are clamped with the limit groove 19, so that the second limit hole 5 is no longer clamped with one end of the clamping rod 21. At the same time, the first rotating gear 8 cannot rotate under the limiting action of the clamping rod 21 and the limit block 22. At this time, the operator can rotate the rotating handle 3 so that the steel pipe 37 and the frame 36 welded on one side are rotated 180 degrees synchronously with the fixed component until the clamping groove 6 opened on the rotating handle 3 is clamped with the other clamping block 35. The operator can then fully weld the frame 36 and the steel pipe 37 on the other side.
