[0002] Butterfly reinforcement is a commonly used building material, which plays a supporting role in highway and railway tunnel reinforcement and grid arch projects. The butterfly reinforcement is welded by two splayed reinforcements. During processing, the two splayed reinforcements are placed on the welding tooling, and the contact points of the two splayed reinforcements are automatically welded by a welding robot. At the same time, the welding tooling clamps the two splayed reinforcements and flips them. After flipping, both sides of the contact points are welded. The butterfly reinforcement is automatically welded by the butterfly reinforcement robot through the flipping mechanism on the welding tooling, which has the characteristics of simple and fast operation and high production speed.

[0003] In tunnel construction, the welding quality of butterfly bars is directly related to the safety and durability of the entire structure. However, when the eight-shaped bars enter the welding fixture from the loading rack, the position between the contact points of the two eight-shaped bars will shift, or when the welding fixture clamps the corresponding eight-shaped bars and flips them, the position of the contact points of the eight-shaped bars will also shift, resulting in the shape of the welded butterfly bars being misaligned, reducing the quality of welding, and thus affecting the stability of the butterfly bar structure.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Example:

[0034] A butterfly tendon automatic welding device, such as Figure 1 As shown, it includes a tool body 1, a positioning assembly 2 and a flip assembly 3. The tool body 1 is the basic structure of the entire device, which is used to support and fix the ribs. The tool body 1 includes a first support frame 11, a second support frame 12 and a rib mounting portion 13. Among them, the rib mounting portion 13 is located between the first support frame 11 and the second support frame 12, and the rib mounting portion 13 is firmly supported by the first support frame 11 and the second support frame 12.

[0035] like Figure 1-3 As shown, in this embodiment, the rib mounting portion 13 includes a fixed plate 131 and a movable plate 132, and cylinders 14 are fixed at both ends of the fixed plate 131, and the cylinder 14 is installed at the side wall of the fixed plate 131, and connecting blocks 141 are correspondingly provided at both ends of the movable plate, and the connecting block 141 is coaxially arranged with the telescopic direction of the cylinder 14, and the telescopic end of the cylinder 14 passes through the fixed plate 131 and is connected to the connecting block 141 on the movable plate 132. Through the telescopic movement of the cylinder 14, the distance between the fixed plate 131 and the movable plate 132 can be adjusted, so as to adapt to ribs of different widths, so as to clamp the ribs between the fixed plate 131 and the movable plate 132.

[0036] In addition, if Figure 1-3 As shown, in order to ensure the stability of the movement of the movable plate 132, four groups of guide members 15 are also provided on the upper and lower surfaces of the splayed rib mounting portion 13, and each group of guide members 15 includes a fixed seat 151, a guide rod 152 and a guide seat 153. Among them, the fixed seat 151 is located on the upper and lower surfaces of the fixed plate 131, and the guide seat 153 is located on the upper and lower surfaces of the movable plate 132, and the fixed seat 151 and the guide seat 153 in each group are coaxially arranged. The guide rod 152 is connected between the fixed seat 151 and the guide seat 153, and the length of the guide rod 152 is greater than the distance between the fixed plate 131 and the movable plate 132, one end of the guide rod 152 is fixedly connected to the fixed seat 151, and the other end is slidably connected to the guide seat 153. The main function of the guide member 15 is to guide the movable plate 132 to move along a predetermined track, to ensure that the movable plate 132 will not deviate when adjusting the distance, thereby further ensuring the positioning accuracy and welding quality of the splayed rib.

[0037] like Figure 1 and 4As shown, in this embodiment, the positioning assembly 2 is a key component to ensure the accurate positioning of the ribs. The positioning assembly 2 is located in the rib mounting portion 13, and the positioning assembly 2 is provided with multiple groups, and the multiple groups of positioning assemblies 2 are linearly arranged in the rib mounting portion 13, and each group of positioning assemblies 2 can evenly support and position the corresponding two ribs. Among them, the positioning assembly 2 includes a clamping block 21 and an adjusting member 22, and the adjusting member 22 includes a fixed block and an adjusting rod. The fixed block is fixedly connected to the side wall of the fixed plate 131 and the opposite side of the movable plate 132, and the adjusting rod is threadedly connected to the middle part of the fixed block and abuts against the clamping block 21, so that a clamping space for clamping the ribs is formed between the four clamping blocks 21. Through the cooperation of the fixed block and the adjusting rod, the position of the clamping block 21 can be accurately adjusted, so as to clamp the ribs, and ensure that the contact points of the ribs on the fixed plate 131 and the ribs on the movable plate 132 can be accurately aligned, thereby improving the welding quality.

[0038] like Figure 1 and 4 As shown, in this embodiment, the positioning assembly 2 also includes a magnetic component 23, which is fixed on the side walls of the movable plate 132 and the fixed plate 131 and corresponds to the positions of the two ends of the figure-eight ribs. The figure-eight ribs are adsorbed on the fixed plate 131 and the movable plate 132 by the magnetic component 23, thereby achieving preliminary fixation of the figure-eight ribs, reducing the displacement of the figure-eight ribs during welding, and improving the positioning stability of the figure-eight ribs.

[0039] like Figure 1 and 4 As shown, in this embodiment, a width limiter 16 is provided on the rib mounting portion 13, and the width limiter 16 is located between two adjacent groups of positioning components 2. The width limiter 16 includes a limiter shaft 161 and an abutment block 162, the abutment block 162 is fixedly connected to the side wall of the fixed plate 131 close to the side of the movable plate 132, the limiter shaft 161 is movably connected to the side wall of the movable plate 132, and the limiter shaft 161 corresponds to the position of the abutment block. According to the width between the two corresponding ribs, the length of the limiter shaft 161 on the movable plate 132 is adjusted so that the limiter shaft 161 abuts against the abutment block 162. At this time, the welding points of the ribs on the fixed plate 131 and the ribs on the movable plate 132 are in contact with each other.

[0040] like Figure 1-3As shown, in this embodiment, the flip assembly 3 is used to realize the automatic flipping function of the rib mounting portion 13 to improve the welding efficiency. The flip assembly 3 includes a flip driving member 31, which is fixed to one side of the first support frame 11, and a first bearing mounting seat 33 is fixed to the top of the first support frame 11, and the first bearing mounting seat 33 is connected to the first rotating shaft 34, and the first rotating shaft 34 is connected to the rib mounting portion 13. In addition, a second bearing mounting seat 36 is fixed to the top of the second support frame 12, and the second bearing mounting seat 36 is connected to the second rotating shaft 37, and the second rotating shaft 37 is connected to the rib mounting portion 13.

[0041] When working, the flip driving member 31 meshes with the driven gear 35 on the first rotating shaft 34 through the driving gear 32 on its output shaft, thereby driving the first rotating shaft 34 to rotate. Since the first rotating shaft 34 is fixedly connected to the rib mounting portion 13, when the flip driving member 31 is working, it can drive the rib mounting portion 13 to flip. This structure enables the rib to flip automatically during welding without manual intervention, greatly improving the automation and efficiency of welding.

[0042] like Figure 5 As shown, a welding head 4 is provided on one side of the tool body 1, and a plurality of groups of splayed ribs in the tool body 1 can be welded into butterfly ribs through the welding head 4, thereby realizing automatic welding and improving work efficiency.

[0043] Working principle: The ribs are grouped in pairs from the feeding mechanism into the rib installation part 13, wherein the rib installation part 13 can accommodate multiple groups of ribs. The ribs are adsorbed by the magnetic suction part 23, and then the length of the limit shaft 161 is adjusted so that its length is equal to the width of the two corresponding ribs. The cylinder 14 is started to move the movable plate 132 toward the fixed plate 131. When the movable plate 132 contacts the ribs in the fixed plate 131, the movable plate 132 stops moving, and the positions of the two ribs are adjusted by the positioning component 2 so that the contact points of the two ribs are accurately aligned, and the welding head 4 is used for automatic welding. The rib installation part 13 is then driven to flip by the flipping component 3. If the position of the ribs is offset during the flipping process, the position of the ribs is adjusted again by the positioning component 2 so that both sides of the contact point of the two ribs can be welded.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
