[0002] A tent mainly consists of a framework and an outer fabric. The framework of the tent, i.e., the bracket, needs to undergo multiple welding operations to form a whole. The brackets of tents usually have various shapes and complex welding positions. Therefore, semi-automatic welding machines are generally used for welding the brackets of tents. The semi-automatic welding machine can flexibly adjust the welding path according to the shape of the bracket to ensure the welding quality.

[0003] A patent document with the publication number CN218518046U discloses a special-shaped bracket assembly welding device, which includes a frustum, a plurality of adjusting parts, and a clamping part. The adjusting part includes a spherical support fixed on the top surface of the frustum, a spherical shell rotatably sleeved on the spherical support, a horizontal square tube fixed to the top end of the spherical shell at the bottom, and a support beam slidably sleeved in the inner cavity of the horizontal square tube. The bottom end of the clamping part is rotatably connected to the inner end of the support beam; it solves the problem that it is not convenient to fix and position special-shaped brackets during welding.

[0004] In traditional technologies, welding devices with fixed positions are generally used for welding tent brackets. However, when a tent is used in the wild, its brackets may be damaged, and it is necessary to perform temporary processing and welding on the damaged bracket parts of the tent. The welding devices in traditional technologies are not convenient for quickly dealing with this situation. Moreover, in the wild environment, when welding brackets of various shapes of tents, it is difficult for workers to accurately grasp the welding positions, and it is difficult to always keep the positions of multiple brackets of different shapes fixed to facilitate subsequent welding. Therefore, there will be problems with poor welding effects.

[0023] 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.

[0024] Embodiment 1: As Figure 1-2 shown, a bracket welding device for tent processing according to an embodiment of the present invention includes an electric welding device 1, the electric welding device 1 is connected with an electric welding head 11 through a circuit, a guide plate 2 is fixedly installed above the electric welding device 1, a first positioning plate 3 is movably installed at one end of the guide plate 2, a second positioning plate 4 is movably installed at the other end of the guide plate 2, and a third positioning plate 5 is movably installed on the side of the guide plate 2; Above the second positioning plate 4, a first clamping assembly 6 is movably installed. Above the first positioning plate 3, two second clamping assemblies 7 are movably installed. Another second clamping assembly 7 is movably installed above the third positioning plate 5. The first clamping assembly 6 and the second clamping assemblies 7 are components made of the same structure. The first clamping assembly 6 and the second clamping assemblies 7 are used to clamp the tent bracket to be welded for movement.

[0025] Specifically, when the tent is used in the wild, if the bracket inside it is damaged and needs to be welded and temporarily processed, the shapes of the tent brackets are various, with different lengths. It is not easy to manually proofread and position them, and it is easy to have errors or welding mistakes during welding. In this device, the second positioning plate 4 and the first positioning plate 3 are movably installed on both sides of the guide plate 2, and the third positioning plate 5 is also movably installed on the side of the electric welding device 1. When carrying it usually, the second positioning plate 4, the first positioning plate 3 and the third positioning plate 5 can be movably rotated and attached to the side of the electric welding device 1. When temporarily processing and welding the tent bracket, rotate and unfold the second positioning plate 4, the first positioning plate 3 and the third positioning plate 5. At this time, place the bracket to be welded on the corresponding first clamping assembly 6 and second clamping assemblies 7. After multiple brackets are fixed, make the welding positions of multiple brackets contact, and precisely weld the contact positions through the welding head 11. The first clamping assembly 6 and the second clamping assemblies 7 can slide on the corresponding first positioning plate 3 or second positioning plate 4 by pushing. And the rotational setting of the first positioning plate 3 and the second positioning plate 4 can further accurately adjust the contact angle of the welding positions of the brackets. This device can fix the brackets to ensure that when welding three parts, symmetry can be maintained, and by positioning first and then welding, the occurrence of welding mistakes can be effectively avoided.

[0026] As Figure 3 shown, a component plate 12 is movably installed on the side of the electric welding device 1. The component plate 12 is used to protect the wire feeding assembly inside the electric welding device 1. A heat dissipation component 13 is installed inside the electric welding device 1. An installation block 14 is fixedly installed on the top of the electric welding device 1. The third positioning plate 5 is movably connected to the installation block 14. The distance between the bottom of the heat dissipation component 13 and the installation block 14 is less than the length of the third positioning plate 5.

[0027] Specifically, a wire feeding assembly is installed inside the electric welding device 1 to ensure that the electric welding head 11 can maintain a longer time during the temporary processing and welding of the tent. When the second positioning plate 4 is flipped above the electric welding device 1, the component plate 12 can be opened to replace and repair the wire feeding assembly inside the electric welding device 1. When the component plate 12 is closed and the second positioning plate 4 is flipped to one side of the component plate 12, the floor area can be reduced. The first positioning plate 3 and the third positioning plate 5 can also be flipped to the same state as the second positioning plate 4 to further reduce the floor area. When the third positioning plate 5 is flipped to a vertical state and is on one side of the heat dissipation component 13, the floor area can be reduced and the heat dissipation component 13 can be protected. The connection method between the third positioning plate 5 and the mounting block 14 is the same as the connection method between the second positioning plate 4 and the guide plate 2.

[0028] As Figures 4-7 shown, two cross-shaped slots one 31 are opened inside the upper part of the first positioning plate 3, and two cross-shaped slots two 41 are opened inside the upper part of the second positioning plate 4. The distance between the two cross-shaped slots one 31 is smaller than the distance between the two cross-shaped slots two 41.

[0029] An installation strip 42 is fixedly installed on one side of the second positioning plate 4 facing the guide plate 2, and a spring telescopic guide post 43 is fixedly installed on the same side of the second positioning plate 4. The end of the spring telescopic guide post 43 is installed with a cross-shaped slot two 41.

[0030] An activity slot 21 is penetrated and opened inside the guide plate 2, and a circular slot 22 is opened inside the activity slot 21. The circular head 44 is movably installed inside the circular slot 22. The spring telescopic guide post 43 is located inside the activity slot 21. The second positioning plate 4 is movably installed with the guide plate 2 through the spring telescopic guide post 43 and the circular head 44. The first positioning plate 3 is installed with the guide plate 2 in the same way.

[0031] A second limiting slot 26 is opened on the side of the guide plate 2, and a first limiting slot 25 is opened on the lower side of the guide plate 2. Both the first limiting slot 25 and the second limiting slot 26 are matched with the installation strip 42.

[0032] Two displacement slots one 23 and two displacement slots two 24 are opened above the guide plate 2. The two displacement slots two 24 are distributed at the outer positions above the guide plate 2, and the two displacement slots one 23 are distributed at the inner positions above the guide plate 2. The displacement slot one 23 and the corresponding cross-shaped slot one 31 are on the same vertical line, and the displacement slot two 24 and the corresponding cross-shaped slot two 41 are on the same vertical line.

[0033] The first clamping assembly 6 includes a sliding strip 61 and a movable shaft 62 movably installed inside the sliding strip 61. A circular frame 63 is movably installed above the sliding strip 61. The circular frame 63 is movably connected with the movable shaft 62. Two cross-shaped blocks 65 are installed below the sliding strip 61. The cross-shaped blocks 65 are matched with the cross-shaped slot two 41 and the displacement slot two 24.

[0034] A plurality of electric drive telescopic columns 64 are evenly distributed and installed inside the circular frame 63. The plurality of electric drive telescopic columns 64 are all arranged towards the central position of the circular frame 63. A ball is movably installed inside one end of the electric drive telescopic column 64 facing the central position of the circular frame 63.

[0035] Specifically, place the tent bracket inside the circular frame 63, and drive a plurality of electric drive telescopic columns 64 to extend through electricity. One end of the plurality of extended electric drive telescopic columns 64 clamps the bracket inside the circular frame 63. The balls at the ends of the plurality of electric drive telescopic columns 64 are movably arranged, and the bracket inside the circular frame 63 can rotate. When the first positioning plate 3, the second positioning plate 4, and the third positioning plate 5 are in the same horizontal state as the guide plate 2, the first clamping assembly 6 can drive the bracket to move. At this time, the cross bar 65 moves inside the second cross groove 41 and the corresponding displacement groove 24. The second clamping assembly 7 can also drive the bracket to move. At this time, the second clamping assembly 7 achieves the effect through the first cross bar groove 31 and the displacement groove 23. When it is necessary for the second positioning plate 4 to continue to rotate on one side of the guide plate 2, first make the second positioning plate 4 drive the first clamping assembly 6 to move away from the guide plate 2. At this time, the spring inside the spring guide post 43 is stretched, and the round head 44 is always inside the circular groove 22. That is, the second positioning plate 4 can drive the first clamping assembly 6 to rotate on one side of the guide plate 2, and the second positioning plate 4 can drive the first clamping assembly 6 to rotate through the rotation of the round head 44 inside the circular groove 22. Before this, the circular frame 63 rotates towards the second positioning plate 4 through the movable shaft 62. When the second positioning plate 4 is in the vertical state and on the side of the component plate 12, the storage state is completed. At this time, the floor area is reduced, and the first clamping assembly 6 is close to the component plate 12, protecting the first clamping assembly 6. Similarly, the first positioning plate 3 and the third positioning plate 5 can also be stored and protect the second clamping assembly 7. When the second positioning plate 4 is in the storage state, the spring inside the spring guide post 43 returns to normal from the stretched state, making the installation strip 42 inserted into the first limit groove 25 to stabilize the connection between the two. When the second positioning plate 4 rotates through the spring telescopic guide post 43 and the round head 44 to be at the same horizontal height as the guide plate 2, the spring inside the spring guide post 43 also experiences the process of stretching and recovery, making the installation strip 42 inserted into the second limit groove 26.

[0036] Embodiment 2: As Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is: the second positioning plate 4 includes a plurality of rotating bar blocks 45. The plurality of rotating bar blocks 45 are combined into the second positioning plate 4. A rotating shaft 46 is movably installed at the end positions of the plurality of adjacent rotating bar blocks 45. The adjacent rotating bar blocks 45 are movably connected through the rotating shaft 46.

[0037] Specifically, the second positioning plate 4 is composed of multiple rotating bar blocks 45. When the first clamping assembly 6 is at the outermost side of the second positioning plate 4, that is, the farthest position from the guiding plate 2, the entire cross bar block 65 is inside the corresponding second cross slot 41. At this time, the multiple rotating bar blocks 45 are in a horizontal state. When the first clamping assembly 6 drives the welding bracket to be welded and the cross bar block 65 to move towards the guiding plate 2, the cross bar block 65 is inserted into the corresponding second displacement slot 24, and the cross bar block 65 will move inside the second cross slot 41. When there is no cross bar block 65 in the second cross slot 41 provided in the rotating bar block 45, this group of rotating bar blocks 45 will rotate through the rotation of the rotating shaft 46, that is, the first clamping assembly 6 is always at the edge of the second positioning plate 4 in a horizontal state, which is beneficial for the circular frame 63 to drive the bracket to rotate under the action of the movable shaft 62, thereby adjusting the angle of the bracket to be welded.

[0038] Working principle: When the tent is used in the wild, if the brackets inside it are damaged and need to be welded and temporarily processed, the shapes of the tent brackets are various, and some are long and some are short, which are not easy to be manually aligned and positioned. When welding, it is easy to have omissions or welding errors. In this device, the second positioning plate 4 and the first positioning plate 3 are movably installed on both sides of the guiding plate 2, and the third positioning plate 5 is also movably installed on the side of the electric welding device 1. When carrying it usually, the second positioning plate 4, the first positioning plate 3 and the third positioning plate 5 can be movably rotated and attached to the side of the electric welding device 1. When temporarily processing and welding the tent brackets, the second positioning plate 4, the first positioning plate 3 and the third positioning plate 5 are rotated and unfolded. At this time, the brackets to be welded are placed on the corresponding first clamping assembly 6 and the second clamping assembly 7. After multiple brackets are fixed, the welding positions of the multiple brackets are contacted, and the contact positions are precisely welded by the electric welding head 11. The first clamping assembly 6 and the second clamping assembly 7 can slide on the corresponding first positioning plate 3 or the second positioning plate 4 by pushing, and the rotational settings of the first positioning plate 3 and the second positioning plate 4 can further accurately adjust the contact angle of the welding positions of the brackets. This device can fix the brackets to ensure that when welding three parts, symmetry can be maintained, and by positioning first and then welding, the occurrence of welding error situations can be effectively avoided.

[0039] Place the tent support inside the circular frame 63, and drive multiple electric drive telescopic columns 64 to extend through electricity. One end of the multiple extended electric drive telescopic columns 64 clamps the support inside the circular frame 63. The balls at the ends of the multiple electric drive telescopic columns 64 are movably arranged, and the support inside the circular frame 63 can rotate. When the first positioning plate 3, the second positioning plate 4, and the third positioning plate 5 are in the same horizontal state as the guide plate 2, the first clamping assembly 6 can drive the support to move. At this time, the cross bar 65 moves inside the second cross slot 41 and the corresponding displacement slot 24. The second clamping assembly 7 can also drive the support to move. At this time, the second clamping assembly 7 achieves the effect through the first cross bar slot 31 and the first displacement slot 23. When the second positioning plate 4 needs to continue to rotate on one side of the guide plate 2, first make the second positioning plate 4 drive the first clamping assembly 6 to move away from the guide plate 2. At this time, the spring inside the spring guide post 43 is stretched, and the round head 44 is always inside the circular slot 22. That is, the second positioning plate 4 can drive the first clamping assembly 6 to rotate on one side of the guide plate 2, and the second positioning plate 4 can drive the first clamping assembly 6 to rotate through the rotation of the round head 44 inside the circular slot 22. Before this, the circular frame 63 rotates towards the second positioning plate 4 through the movable shaft 62. When the second positioning plate 4 is in the vertical state and is on the side of the component plate 12, the storage state is completed. At this time, the floor area is reduced, and the first clamping assembly 6 is close to the component plate 12, protecting the first clamping assembly 6. Similarly, the first positioning plate 3 and the third positioning plate 5 can also be stored and protect the second clamping assembly 7. When the second positioning plate 4 is in the storage state, the spring inside the spring guide post 43 returns to normal from the stretched state, so that the installation strip 42 is inserted into the first limit slot 25 to stabilize the connection between the two. When the second positioning plate 4 rotates to the same horizontal height as the guide plate 2 through the spring telescopic guide post 43 and the round head 44, the spring inside the spring guide post 43 also experiences the process of stretching and recovery, so that the installation strip 42 is inserted into the second limit slot 26.
