[0002] With the widespread adoption of modern automation across various industries, reducing labor intensity, improving production efficiency, and ensuring the stable operation of production equipment with less human intervention has become particularly important.

[0003] The traditional method involves fixing the wire feeder in one position and connecting it to the welding head with a wire feeding hose. As the welding head moves forward or backward, the wire feeding hose changes from straight to bent, which seriously affects the welding quality. A solution is needed. Utility Model Content

[0004] To overcome the problem that the traditional method involves fixing the wire feeder in one position and connecting it to the welding head with a wire feeding hose, which causes the wire feeding hose to change from straight to bent as the welding head moves forward or backward, thus seriously affecting the welding quality, a wire feeder follow-up device is proposed.

[0005] The technical solution of this utility model is as follows: a wire feeder follow-up device, including a moving mechanism and a rotating mechanism; a rotating mechanism is provided on one side of the moving mechanism, and a fixed mechanism is provided on the other side of the moving mechanism; a wire feeder body is provided at the upper end of the moving mechanism, and a machine head is provided at the lower end of the rotating mechanism; one end of the machine head is hinged to the output end of a hydraulic cylinder, and the hydraulic cylinder is fixedly connected to the side wall of the frame; the rotating mechanism includes a first connecting rod, a first hole, a rotating column, a second connecting rod, a second hole, a third connecting rod, a third hole, and a pin; the upper end of one side of the first connecting rod is rotatably mounted on one side of the moving mechanism, the lower end of one side of the first connecting rod has a first hole through it, the inner wall of the first hole is rotatably mounted on the inner wall of the first hole, the lower part of the limiting plate near the lower end of the first connecting rod is fixedly connected to the lower end of one side of the rotating column, the upper end of one side of the rotating column has a second hole through it, the inner wall of the second hole is rotatably mounted on the outer wall of the pin, the outer wall of the pin is rotatably mounted on the outer wall of the pin, the upper end of one side of the third connecting rod has a third hole through it, and the pin is rotatably mounted inside the third hole.

[0006] Furthermore, the moving mechanism includes a limiting block, a first slot, a limiting plate, a first through hole, a sliding block, and a fixing block. The limiting block has a first slot on one side, and a limiting plate is fixedly connected to the side of the limiting block near the first slot. The limiting plate has a first through hole through one side. The sliding block is slidably installed on the inner wall of the sliding block, and a fixing block is fixedly connected to the lower end of one side of the sliding block. The upper end of one side of the first connecting rod is rotatably installed on one side of the fixing block.

[0007] Furthermore, the fixing mechanism includes a fixing plate, a second through hole, and a bolt; the end of the limiting block away from the first connecting rod is fixedly connected to the fixing plate, and four second through holes are evenly opened through one end of the fixing plate, with bolts threaded onto the inner wall of the second through holes.

[0008] Furthermore, the first slot and the first through hole are interconnected, and the sidewall of the sliding block slides simultaneously on the inner walls of both the first slot and the first through hole.

[0009] Furthermore, the lower end of the first connecting rod, the upper end of the second connecting rod, and the upper end of the third connecting rod are rotatably mounted on the side wall of the pin.

[0010] Furthermore, one side of the first link is attached to one side of the second link, and one side of the second link is attached to one side of the third link.

[0011] Furthermore, the fixing block is U-shaped, with the two sides of the opening end of the fixing block fitting against the other side of the limiting plate, the other end of the third connecting rod slidingly connected to the machine head, a welding gun installed on one side of the machine head, and the wire feeder body fixedly connected to the upper end of the sliding block.

[0012] The beneficial effects of this utility model are as follows: First, the wire passes through the wire feeder body and reaches the lower end of the head to connect to the welding gun. Then, the rotating mechanism is fixed to the working position using bolts, and the hydraulic cylinder is fixed to the side wall of the wire feeder. Subsequently, by opening the hydraulic cylinder, the output end of the hydraulic cylinder extends and pushes the head forward. When the head moves forward, it pulls the third connecting rod forward. The third connecting rod moves the first and second connecting rods forward through the pin. Since the other end of the second connecting rod is rotatably mounted on the side wall of the rotating column, the rotating column changes the movement trajectory of the second connecting rod. The second connecting rod rotates around the rotating column. When the second connecting rod rotates, it pulls the pin diagonally downward. The pin pulls the first connecting rod. Since the first connecting rod is rotatably mounted on one side of the sliding block, the sliding block is pulled diagonally downward. Because the sliding block is limited... Located on the inner wall of the limiting block and the first through hole, the limiting block and the first through hole force the sliding block to move vertically. When the sliding block moves vertically downward, it pulls the upper wire feeder downward. The downward movement of the wire feeder can adjust the length of the wire. When the output end of the oil cylinder retracts into the tube, the machine head moves backward. The machine head pushes the third connecting rod to move backward. The third connecting rod pushes the pin shaft to move backward. The pin shaft pushes the second connecting rod. Since the second connecting rod is rotatably mounted on the side wall of the rotating column, the second connecting rod rotates upward. When the second connecting rod rotates, it changes the original movement trajectory of the pin shaft. The second connecting rod forces the pin shaft to move upward. The upward movement of the pin shaft pushes the first connecting rod to move upward. When the first connecting rod moves upward, it pushes the wire feeder to move upward. This allows the wire feeder body and the machine head to move synchronously, ensuring that the wire is in a straight tension state. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-7This utility model provides an embodiment: a wire feeder follow-up device, including a moving mechanism 1 and a rotating mechanism 2; the rotating mechanism 2 is provided on one side of the moving mechanism 1, and a fixing mechanism 3 is provided on the other side of the moving mechanism 1; a wire feeder body 4 is provided at the upper end of the moving mechanism 1, and a machine head 5 is provided at the lower end of the rotating mechanism 2; one end of the machine head 5 is hinged to the output end of a hydraulic cylinder 6, and the hydraulic cylinder 6 is fixed to the side wall of the frame; the rotating mechanism 2 includes a first connecting rod 21, a first hole 22, a rotating column 23, a second connecting rod 24, a second hole 25, a third connecting rod 26, a third hole 27, and a pin 28; the moving mechanism... The upper end of the first connecting rod 21 is rotatably mounted on one side of the structure 1. The lower end of the first connecting rod 21 is provided with a first hole 22. The inner wall of the first hole 22 is rotatably mounted with a pin 28. The lower end of the limiting plate 13 near the first connecting rod 21 is fixed to the lower end of the rotating column 23. The upper end of the rotating column 23 is provided with a second hole 25. The inner wall of the second hole 25 is rotatably mounted on the outer wall of the pin 28. The outer wall of the pin 28 is rotatably mounted with a third connecting rod 26. The upper end of the third connecting rod 26 is provided with a third hole 27. The pin 28 is rotatably mounted inside the third hole 27.

[0023] In use, the wire first passes through the wire feeder body 4 to the lower end of the head 5, which connects to the welding torch. Then, the rotating mechanism 2 is fixed to the work site using bolts 33. The hydraulic cylinder 6 is fixed to the side wall of the wire feeder 4. Subsequently, by opening the hydraulic cylinder 6, the output end of the hydraulic cylinder 6 extends, pushing the head 5 forward. When the head 5 moves forward, it pulls the third connecting rod 26 forward. The third connecting rod 26 moves the first connecting rod 21 and the second connecting rod 24 forward through the pin 28. Since the other end of the second connecting rod 24 is rotatably mounted on the side wall of the rotating column 23, the rotating column 23 changes the movement trajectory of the second connecting rod 24. The second connecting rod 24 rotates around the rotating column 23. When the second connecting rod 24 rotates, it pulls the pin 28 diagonally downward. The pin 28 pulls the first connecting rod 21. Since the first connecting rod 21 is rotatably mounted on one side of the sliding block 15, the sliding block 15 is pulled diagonally downward. The sliding block 15 is limited to the inner wall of the limiting block 11 and the first through hole 14. The limiting block 11 and the first through hole 14 force the sliding block 15 to move vertically. When the sliding block 15 moves vertically downward, it pulls the upper wire feeder 4 downward. The downward movement of the wire feeder 4 can adjust the length of the wire. When the output end of the oil cylinder 6 retracts into the tube, the machine head 5 moves backward. The machine head 5 pushes the third connecting rod 26 to move backward. The third connecting rod 26 pushes the pin 28 to move backward. The pin 28 pushes the second connecting rod 24. Since the second connecting rod 24 is rotatably mounted on the side wall of the rotating column 23, the second connecting rod 24 rotates upward. When the second connecting rod 24 rotates, it changes the original movement trajectory of the pin 28. The second connecting rod 24 forces the pin 28 to move upward. The upward movement of the pin 28 pushes the first connecting rod 21 to move upward. When the first connecting rod 21 moves upward, it pushes the wire feeder 4 to move upward, which can adjust the length of the wire.

[0024] Please see Figure 5 and Figure 6 In this embodiment, the moving mechanism 1 includes a limiting block 11, a first slot 12, a limiting plate 13, a first through hole 14, a sliding block 15, and a fixing block 16. The first slot 12 is provided on one side of the limiting block 11. The limiting plate 13 is fixedly connected to the side of the limiting block 11 near the first slot 12. The first through hole 14 is provided through one side of the limiting plate 13. The sliding block 15 is slidably installed on the inner wall of the sliding block 15. The fixing block 16 is fixedly connected to the lower end of one side of the sliding block 15. The upper end of one side of the first connecting rod 21 is rotatably installed on one side of the fixing block 16. The sliding block 15 provides a downward force to the first connecting rod 21. The limiting block 11 restricts the sliding direction of the sliding block 15.

[0025] Please see Figure 7 In this embodiment, the fixing mechanism 3 includes a fixing plate 31, a second through hole 32 and a bolt 33; the fixing plate 31 is fixedly connected to one end of the limiting block 11 away from the first connecting rod 21, and four second through holes 32 are evenly opened through one end of the fixing plate 31. The inner wall of the second through hole 32 is threaded with a bolt 33, and the fixing plate 31 fixes the device at the working location.

[0026] Please see Figure 3 and Figure 4 In this embodiment, the first slot 12 and the first through hole 14 are interconnected, and the side wall of the sliding block 15 slides on the inner wall of both the first slot 12 and the first through hole 14, which allows the sliding block 15 to slide smoothly up and down.

[0027] Please see Figure 5 and Figure 6 In this embodiment, the lower end of the first connecting rod 21, the upper end of the second connecting rod 24, and the upper end of the third connecting rod 26 are rotatably mounted on the side wall of the pin 28, and the first connecting rod 21, the second connecting rod 24, and the third connecting rod 26 are connected together by the pin 28.

[0028] Please see Figure 5 and Figure 6 In this embodiment, one side of the first link 21 is attached to one side of the second link 24, and one side of the second link 24 is attached to one side of the third link 26. The two links fit together, making the device more secure.

[0029] Please see Figure 3 and Figure 4 In this embodiment, the fixing block 16 is U-shaped, and the two sides of the opening end of the fixing block 16 are in contact with the other side of the limiting plate 13. The other end of the third connecting rod 26 is slidably connected to the machine head 5. A welding gun is installed on one side of the machine head 5. The wire feeder body 4 is fixedly connected to the upper end of the sliding block 15. The fixing block 16 connects the first connecting rod 21 with the sliding block 15.

[0030] Working principle: The rotating mechanism 2 is fixed at the working location, and the hydraulic cylinder 6 is fixed to the side wall of the wire feeder 4. When the hydraulic cylinder 6 is opened, its output end extends, pushing the head 5 forward. As the head 5 moves forward, it pulls the third connecting rod 26 forward. The third connecting rod 26, through the pin 28, moves the first connecting rod 21 and the second connecting rod 24 forward. Since the other end of the second connecting rod 24 is rotatably mounted on the side wall of the rotating column 23, the rotating column 23 changes the trajectory of the second connecting rod 24. The second connecting rod 24 rotates around the rotating column 23. When the second connecting rod 24 rotates, it pulls the pin 28 diagonally downwards. The pin 28 pulls the first connecting rod 21. Since the first connecting rod 21 is rotatably mounted on one side of the sliding block 15, the sliding block 15 is pulled diagonally downwards. Because the sliding block 15 is limited within the limiting block 11 and the first through hole 14... The wall, the limiting block 11, and the first through hole 14 force the sliding block 15 to move vertically. When the sliding block 15 moves vertically downward, it pulls the upper wire feeder 4 downward. The downward movement of the wire feeder 4 can adjust the length of the wire. When the output end of the oil cylinder 6 retracts into the tube, the machine head 5 moves backward. The machine head 5 pushes the third connecting rod 26 to move backward. The third connecting rod 26 pushes the pin 28 to move backward. The pin 28 pushes the second connecting rod 24. Since the second connecting rod 24 is rotatably mounted on the side wall of the rotating column 23, the second connecting rod 24 rotates upward. When the second connecting rod 24 rotates, it changes the original movement trajectory of the pin 28. The second connecting rod 24 forces the pin 28 to move upward. The upward movement of the pin 28 pushes the first connecting rod 21 to move upward. When the first connecting rod 21 moves upward, it pushes the wire feeder 4 to move upward, which can adjust the length of the wire and prevent the wire from bending due to excessive length, thus affecting the welding result.
