DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0035] Example 1

The two movable frames 31 are respectively threadedly connected to the upper and lower parts of the bidirectional screw 32. The rear parts of the movable frames 31 are both slidably connected to the support frame 2. The left and right sides of the front part of the upper movable frame 31 are connected to the first extrusion piece 34. The lower parts of the first extrusion pieces 34 are all trapezoidal. There are two second extrusion pieces 36. The two second extrusion pieces 36 are respectively connected to the left and right sides of the front part of the lower movable frame 31. The upper parts of the second extrusion pieces 36 are all trapezoidal. The reinforcement assembly is arranged at the front part of the upper movable frame 31.

[0038] like Figure 5 As shown, the reinforcement component includes a clamping frame 33 and a tension spring 35. There are two clamping frames 33, which are respectively slidably connected to the left and right sides of the front part of the upper movable frame 31. The clamping frame 33 is located in front of the first extrusion member 34. There are two tension springs 35, which are respectively connected between the clamping frame 33 and the upper movable frame 31, and the tension springs 35 are all wound on the clamping frame 33.

[0039] like Figure 2 , Figure 6 and Figure 7As shown, the stabilizing mechanism 4 includes a rotating frame 41, a piston rod 42, a return spring 43, an air cylinder 44, a suction cup 45 and a first torsion spring 46. There are two air cylinders 44, which are respectively installed on the left and right sides of the front lower part of the support frame 2. There are two suction cups 45, which are respectively connected to the lower side of the air cylinder 44, and the suction cup 45 is connected to the air cylinder 44. There are two piston rods 42, which are respectively slidably connected to the air cylinder 44. There are two return springs 43, which are respectively installed on the left and right sides of the front lower part of the support frame 2. There are two suction cups 45, which are respectively connected to the lower side of the air cylinder 44, and the suction cup 45 is connected to the air cylinder 44. The return springs 43 are respectively connected between the piston rod 42 and the upper side of the air cylinder 44, and the return springs 43 are all wound on the piston rod 42. There are two rotating frames 41, and the two rotating frames 41 are respectively rotatably connected to the left and right parts of the upper front side of the support frame 2. The lower part of the rotating frame 41 and the front upper part of the piston rod 42 are squeezed together, and the upper part of the rotating frame 41 and the rear lower side of the upper moving frame 31 are squeezed together. A first torsion spring 46 is connected between the rotating frame 41 and the support frame 2, and the first torsion spring 46 is all wound on the support frame 2.

[0040] When people need to weld the buckle to the iron bed frame 1, they can use the buckle welding device 21 to operate it. First, manually move the buckle to fit with the inner rear wall of the iron bed frame 1. At this time, the buckle will also be located between the first extrusion piece 34 and the second extrusion piece 36. Then manually rotate the bidirectional screw 32 to drive the movable frame 31 to drive the first extrusion piece 34 and the second extrusion piece 36 to move inward, so that the first extrusion piece 34 and the second extrusion piece 36 clamp the buckle. Then people can release the buckle. At the same time, when the movable frame 31 moves inward, the upper movable frame 31 will also drive the clamping frame 33 to move downward. When the clamping frame 33 moves downward to contact with the upper part of the buckle, the buckle will squeeze the clamping frame 33 to the side away from each other, and then the stored force spring will be Stretch, at this time, under the action of the force storage spring, the clamping frame 33 will clamp the buckle, so that the buckle can be reinforced and the stability of the buckle can be improved. Then people can remove the welder 21 from the support frame 2 and open the welder 21, and then hold the welder 21 to weld the joint between the buckle and the iron bed frame 1. When welding is completed, close the welder 21, and then manually clamp the welder 21 back to the support frame 2, and then manually rotate the bidirectional screw 32 in the opposite direction to drive the moving frame 31 to drive the clamping frame 33, the first extrusion piece 34 and the second extrusion piece 36 to move outward, so that the first extrusion piece 34 and the second extrusion piece 36 are away from the iron bed frame 1, and when the moving frame 31 moves outward, the upper moving frame 31 will also drive the clamping frame 33, the first extrusion piece 34 and the second extrusion piece 36 to move outward. The frame 33 moves upward, and when the clamping frame 33 moves upward away from the buckle, under the action of the tension spring 35, the clamping frame 33 moves to the side close to each other, and then people can move the support frame 2, the movable frame 31, the first extrusion piece 34 and the second extrusion piece 36 backward to take the iron bed frame 1 out of the buckle welding device. When people are welding the buckle, they may accidentally bump the support frame 2. In order to facilitate people to perform welding work, the stability of the support frame 2 can be improved. When people are performing welding work, the suction cup 45 will absorb the ground, which can improve the stability of the support frame 2 during welding, and when the movable frame 31 moves inward, the upper movable frame 31 will squeeze the upper part of the rotating frame 41 downward, and the rotating frame 41 will rotate at this time. , then the first torsion spring 46 is twisted, and when the rotating frame 41 rotates, the rotating frame 41 will pull the piston rod 42 upward, and then the return spring 43 is stretched. At this time, the piston rod 42 will evacuate the suction cup 45 through the air cylinder 44, which can increase the adsorption force of the suction cup 45. When the welding is completed, the movable frame 31 moves outward, and the upper movable frame 31 no longer squeezes the rotating frame 41. Under the action of the first torsion spring 46, the rotating frame 41 will rotate in the opposite direction and no longer squeeze the piston rod 42. At this time, under the action of the return spring 43, the piston rod 42 will move downward and reset, and pump air to the suction cup 45 through the air cylinder 44, which can reduce the adsorption force of the suction cup 45, and then people can easily move the support frame 2.In summary, the buckle on the iron bed frame 1 can be welded, and during the welding process, the buckle can be automatically fixed without manual fixation, thereby facilitating welding work.

[0041] Example 2

[0042] On the basis of Example 1, Figure 2 , Figure 8 and Fig. 9 As shown, it also includes a knocking mechanism 5, which includes an extrusion frame 51, a knocking piece 52 and a pressure spring 53. There are two extrusion frames 51, and the two extrusion frames 51 are respectively fixed to the upper side of the piston rod 42. The rear part of the extrusion frame 51 is provided with a plurality of right-angled triangle blocks. There are two knocking pieces 52, and the two knocking pieces 52 are respectively slidably connected to the left and right sides of the upper part of the support frame 2. The rear part of the knocking piece 52 and the rear part of the extrusion frame 51 are extruded and matched. There are two pressure springs 53, and the two pressure springs 53 are respectively connected between the knocking piece 52 and the support frame 2, and the pressure springs 53 are all wound on the knocking piece 52.

[0043] When the piston rod 42 moves upward, the piston rod 42 will also drive the extrusion frame 51 to move upward. When the inclined surface of the right-angled triangle block at the rear of the extrusion frame 51 moves to contact with the rear of the knocking piece 52, the extrusion frame 51 will squeeze the knocking piece 52 backward, and the pressure spring 53 will be stretched. When the inclined surface of the right-angled triangle block at the rear of the extrusion frame 51 moves away from the rear of the knocking piece 52, under the action of the pressure spring 53, the knocking piece 52 moves forward and knocks the iron bed frame 1, so that impurities attached to the iron bed frame 1 can be shaken off, which is beneficial for people to carry out welding work later. Subsequently, when the piston rod 42 needs to drive the extrusion frame 51 to move downward, the knocking piece 52 is manually pulled backward first, which will not affect the downward movement of the extrusion frame 51. After the extrusion frame 51 moves downward and resets, people can release the knocking piece 52. In summary, impurities on the iron bed frame 1 can be shaken off before welding.

[0044] like Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, it also includes a reinforcement mechanism 6, which includes a support member 61, a pushing frame 62, a reinforcement member 63 and a second torsion spring 64. The upper rear part of the support frame 2 is laterally rotatably connected to two reinforcement members 63. The number of the second torsion springs 64 is two, and the two second torsion springs 64 are respectively connected between the rear side of the reinforcement member 63 and the support frame 2. The second torsion spring 64 is wound around the upper rear part of the support frame 2. The number of the support members 61 is two, and the two support members 61 are respectively rotatably connected to the side of the reinforcement member 63 away from each other. The pushing frame 62 is fixed to the upper rear side of the movable frame 31 on the lower side, and the upper part of the pushing frame 62 and the side of the reinforcement member 63 close to each other are squeezed and fitted.

[0045] When the moving frame 31 moves inward, the moving frame 31 on the lower side will also drive the pushing frame 62 to move upward. At this time, the pushing frame 62 will squeeze the reinforcement 63 to rotate, and then the second torsion spring 64 will be twisted, and then the reinforcement 63 will drive the support member 61 to rotate, so that the support member 61 contacts the ground, which can enhance the stability of the support frame 2. Subsequently, when the welding is completed, the moving frame 31 moves outward, and the moving frame 31 on the lower side will also drive the pushing frame 62 to move downward. When the pushing frame 62 moves downward and no longer squeezes the reinforcement 63, under the action of the second torsion spring 64, the reinforcement 63 drives the support member 61 to rotate in the opposite direction. In summary, the stability of the support frame 2 can be enhanced during the welding process.

[0046] like Figure 2 , Fig.12 and Fig.13 As shown, it also includes a guide mechanism 7, which includes a guide member 71, a limit member 72, a return spring 73 and a roller 74. The number of guide members 71 is four, and the four guide members 71 are respectively fixed to the left and right sides of the front middle part of the movable frame 31. The number of rollers 74 is four, and the four rollers 74 are respectively rotatably connected to the middle part of the guide member 71. The number of limit members 72 is eight, and the eight limit members 72 are respectively slidably connected to the front and rear parts of the guide member 71. The inner sides of the limit members 72 are provided with inclined surfaces, and return springs 73 are fixedly connected between the outer sides of the limit members 72 and the guide members 71, and the return springs 73 are all wound around the guide members 71.

[0047] When people need to weld multiple buckles for the iron bed frame 1, they can use the guide mechanism 7 to operate. When the movable frame 31 moves inward, the movable frame 31 will also drive the guide member 71, the limit member 72 and the roller 74 to move inward. When the limit member 72 moves to contact with the rear portion of the iron bed frame 1, the iron bed frame 1 will squeeze the limit member 72 on the same guide member 71 to the side away from each other, and then the return spring 73 is compressed. At this time, under the action of the return spring 73, the limit member 72 will clamp the rear portion of the iron bed frame 1, and the roller 74 will also move to contact with the iron bed frame 1. Subsequently, when people are welding multiple buckles, they need to move the iron bed frame 1 left and right. During movement, the roller 74 will roll. At this time, with the cooperation of the guide member 71 and the limit member 72, when the iron bed frame 1 moves left and right, the front and rear positions of the iron bed frame 1 will not shift. When the iron bed frame 1 moves to the destination, the iron bed frame 1 stops moving, and the roller 74 will also stop rolling. When the welding is completed, when the moving frame 31 moves outward, the moving frame 31 will also drive the guide member 71, the limit member 72 and the roller 74 to move outward. When the limit member 72 moves away from the iron bed frame 1, under the action of the return spring 73, the limit member 72 on the same guide member 71 moves to the side close to each other. In summary, it can assist people in welding multiple buckles.

[0048] like Figure 2 and Fig.14 As shown, it also includes a preheating mechanism 8, which includes a heater 81, a squeezing spring 82, a moving rod 83 and a latch 84. There are two moving rods 83, which are respectively slidably connected to the front side of the moving frame 31. There are two heaters 81, which are respectively installed on the inner sides of the moving rods 83. There are two squeezing springs 82, which are respectively connected between the moving rod 83 and the moving frame 31. The squeezing springs 82 are both wound around the moving rod 83, and the moving rod 83 is provided with a card hole. There are two latches 84, which are respectively slidably connected to the outer side of the front part of the moving frame 31 through a damping sleeve.

[0049] When people need to preheat the joint between the buckle and the iron bed frame 1 during the welding process, they can use the preheating mechanism 8 to operate. First, turn on the heater 81 so that the heater 81 preheats the joint between the buckle and the iron bed frame 1. When the preheating is completed, turn off the heater 81, and then manually move the heater 81 and the moving rod 83 outward, thereby stretching the extrusion spring 82. When the card hole on the moving rod 83 moves to align with the latch 84, stop moving the heater 81 and the moving rod 83, and then manually move the latch 84 moves forward so that the pin 84 is inserted into the card hole on the moving rod 83, so that the moving rod 83 can be fixed after the movement, and then people can weld the joint between the buckle and the iron bed frame 1. When the welding is completed and the iron bed frame 1 is moved away from the buckle welding device, the pin 84 is manually moved backward. When the pin 84 moves backward and no longer limits the moving rod 83, under the action of the extrusion spring 82, the heater 81 and the moving rod 83 move inward. In summary, the joint between the buckle and the iron bed frame 1 can be preheated.
