[0028] Please see Figure 1-7The present invention provides a technical solution: a welding fixture for processing support rods of iron frame beds, including an operating table 1 and a front and rear positioning mechanism, a left and right positioning mechanism, a fixing mechanism, a rotating mechanism and a lifting mechanism.

The end of the long support rod 15 abuts against the end of one side of the short support rod 16. The two short support rods 16 and the two long support rods 15 are combined to form a hollow rectangular structure.

[0032] The operating platform 1 is located inside the lifting frame 17. Both the operating platform 1 and the lifting frame 17 are equipped with a rotating mechanism. The rotating mechanism includes a fourth rotating shaft 18. The fourth rotating shaft 18 is fixed at the center of one side of the operating platform 1. The end of the fourth rotating shaft 18 passes through the top of one side of the lifting frame 17 and is fixed with a first servo motor 19. The first servo motor 19 is fixedly installed on the outer wall of the lifting frame 17. The sixth rotating shaft 32 is fixed at the center of the other side of the operating platform 1. The end of the sixth rotating shaft 32 is installed on the top of one side of the lifting frame 17.

[0033] Both sides of the end of the operating table 1 are provided with grooves 20. A locking rod 21 is installed inside the groove 20. The end of the locking rod 21 is located inside the locking groove 22. The locking groove 22 is opened at the top of the inner side of the lifting frame 17. An opening 23 is opened on the inner side of the groove 20. A lever 24 passes through the opening 23. The end of the lever 24 is fixedly connected to the end of one side of the locking rod 21.

[0034] A fixed frame 25 is provided on the outer side of the lifting frame 17. A lifting mechanism is provided on the fixed frame 25. The lifting mechanism includes a fifth rotating shaft 28, which is installed inside the fixed frame 25. A movable block 29 is provided on the outer side of the fifth rotating shaft 28. A rotating rod 30 is rotatably installed on the top of the movable block 29. The top of the rotating rod 30 is rotatably connected to the bottom of the lifting frame 17. A second servo motor 31 is fixedly installed through the interior of the fixed frame 25 at the end of the fifth rotating shaft 28. The second servo motor 31 is fixedly installed on the outer wall of the fixed frame 25. A sliding groove 26 is provided on the inner wall of the fixed frame 25. A sliding plate 27 is installed inside the sliding groove 26. The side of the sliding plate 27 is fixedly connected to the outer wall of the lifting frame 17.

[0035] The first rotating shaft 3 has opposite threads at both ends inside the groove 2, and the first rotating shaft 3 and the front and rear positioning plates 4 are threadedly connected, while the front and rear positioning plates 4 and the guide rod 5 are slidably connected. At the same time, there are two front and rear positioning plates 4 symmetrically distributed about the central axis of the groove 2, which ensures that when the first rotating shaft 3 rotates, the two front and rear positioning plates 4 can move closer to each other or move further away from each other, so that the two front and rear positioning plates 4 can limit the support frame of different widths, and facilitate the two long support rods 15 on the support frame to abut against the sides of the two front and rear positioning plates 4.

[0036] The operating table 1 is designed with a cross shape, which allows the connection between the long support rod 15 and the short support rod 16 to be suspended in the air, making it convenient to weld the connection between the long support rod 15 and the short support rod 16.

[0037] The fixed plate 7 and the second rotating shaft 8 are threadedly connected, and the bottom of the left and right positioning plates 9 and the top of the operating table 1 abut against each other. There are two left and right positioning plates 9 symmetrically distributed about the central axis of the operating table 1, which ensures that the left and right positioning plates 9 can move left and right when the second rotating shaft 8 rotates. This allows the two left and right positioning plates 9 to limit the support frame of different lengths, and facilitates the placement of the two short support rods 16 on the support frame against the sides of the two left and right positioning plates 9.

[0038] The third rotating shaft 12 has opposite threads at both ends inside the reserved groove 11, and the third rotating shaft 12 and the clamping plate 13 are threadedly connected. There are two clamping plates 13 symmetrically distributed about the central axis of the reserved groove 11. At the same time, the outer wall of the clamping plate 13 abuts against the inner wall of the reserved groove 11, ensuring that when the third rotating shaft 12 rotates, the two clamping plates 13 can move closer to each other, thereby fixing the short support rods 16 of different lengths.

[0039] The lever 21 and the lever 24 are combined to form an "L" shape. The end of the lever 21 is engaged with the slot 22, and the other end of the lever 21 is slidably connected to the groove 20. When the end of the lever 21 is engaged with the slot 22, it can support the operating table 1, so that the operating table 1 can be stably in a horizontal state.

[0040] The fifth rotating shaft 28 is located inside the fixed frame 25 and has opposite threads at both ends. The fifth rotating shaft 28 and the movable block 29 are threadedly connected. There are two movable blocks 29 symmetrically distributed about the central axis of the fixed frame 25. At the same time, the slide groove 26 and the slide plate 27 form a locking sliding structure. The rotating rods 30 are symmetrically distributed about the central axis of the lifting frame 17. This ensures that when the fifth rotating shaft 28 rotates, the two movable blocks 29 can move closer to each other, so that the bottoms of the two rotating rods 30 can move closer to each other. Then, the two rotating rods 30 can push the lifting frame 17 to move upward. When the two movable blocks 29 move away from each other, the bottoms of the two rotating rods 30 can move away from each other, so that the two rotating rods 30 can drive the lifting frame 17 to move downward.

[0041] Working principle: When using the welding fixture for processing the support rod of the iron frame bed, first place the short support rod 16 between the two clamping plates 13, then rotate the third handle 14, and then the third handle 14 drives the third rotating shaft 12 to rotate. Since the third rotating shaft 12 has opposite threads at both ends inside the reserved groove 11, and the third rotating shaft 12 and the clamping plate 13 are threadedly connected, and there are two clamping plates 13 symmetrically distributed about the central axis of the reserved groove 11, and the outer wall of the clamping plate 13 abuts against the inner wall of the reserved groove 11, the two clamping plates 13 move closer to each other, and then the two clamping plates 13 fix the short support rod 16, and then fix the other short support rod 16.

[0042] Next, place the sides of the two long support rods 15 against the sides of the two front and rear positioning plates 4, and then rotate the first handle 6. The first handle 6 then drives the first rotating shaft 3 to rotate. Since the first rotating shaft 3 has opposite threads at both ends inside the groove 2, and the first rotating shaft 3 and the front and rear positioning plates 4 are threadedly connected, and the front and rear positioning plates 4 and the guide rod 5 are slidably connected, and there are two front and rear positioning plates 4 symmetrically distributed about the central axis of the groove 2, the two front and rear positioning plates 4 move closer to each other. At the same time, the two front and rear positioning plates 4 drive the two long support rods 15 to move closer to each other until the sides of the long support rods 15 are flush with the ends of the short support rods 16.

[0043] Next, rotate the second handle 10, which in turn drives the second rotating shaft 8 to rotate. Since the fixed plate 7 and the second rotating shaft 8 are threadedly connected, and the bottom of the left and right positioning plates 9 and the top of the operating table 1 abut against each other, and there are two left and right positioning plates 9 symmetrically distributed about the central axis of the operating table 1, the two left and right positioning plates 9 move closer to each other. At the same time, the two left and right positioning plates 9 drive the two short support rods 16 to move closer to each other until the ends of the two long support rods 15 contact the sides of the two short support rods 16, so that the two short support rods 16 and the two long support rods 15 combine to form a hollow rectangular structure. Then, the connection between the short support rods 16 and the long support rods 15 can be welded.

[0044] Next, push the lever 24. At this time, the lever 24 drives the locking lever 21 to move inside the slot 20, so that the locking lever 21 separates from the slot 22. Then, start the first servo motor 19. At this time, the first servo motor 19 drives the fourth rotating shaft 18, the operating table 1 and the sixth rotating shaft 32 to rotate 180 degrees. At the same time, the two long support rods 15 and two short support rods 16 fixed on the top of the operating table 1 rotate 180 degrees. Since the operating table 1 is designed with a "+" shaped structure, the connection between the long support rods 15 and the short support rods 16 can be suspended in the air, which is convenient for welding the connection between the long support rods 15 and the short support rods 16.

[0045] Next, start the first servo motor 19 to rotate the welded support frame 180 degrees to reset it. Then rotate the third handle 14 to make the two clamping plates 13 move away from each other, so that the support frame can be disassembled. At this time, the support frame can be removed.

[0046] By starting the second servo motor 31, the second servo motor 31 drives the fifth rotating shaft 28 to rotate. Since the fifth rotating shaft 28 has opposite threads at both ends inside the fixed frame 25, and the fifth rotating shaft 28 and the movable block 29 are threadedly connected, and there are two movable blocks 29 symmetrically distributed about the central axis of the fixed frame 25, and the slide groove 26 and the slide plate 27 form a locking sliding structure, and the rotating rod 30 is symmetrically distributed about the central axis of the lifting frame 17, the two movable blocks 29 move closer to each other, so that the bottoms of the two rotating rods 30 can move closer to each other, and then the two rotating rods 30 can push the lifting frame 17 to move upward, so that the operating table 1 on the lifting frame 17 and the support frame fixed on the top of the operating table 1 move upward, so that the height of the operating table 1 can be adjusted, which facilitates the operation of the operating table 1.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
