[0018] See also Figure 1-3 The utility model provides a technical solution: a high-precision welding device for refrigeration pipe parts, comprising:

[0019] The base 1 has two support rods 2 fixedly welded on the top wall of the base 1, and a rotating rod 3 is rotatably installed on the two support rods 2 through bearings. Two pairs of symmetrically arranged connecting rods 4 are fixedly welded on the rotating rod 3, and a mounting seat 5 is fixedly welded on the outer end of the connecting rod 4. A rotating drum 6 is rotatably installed on the mounting seat 5 through a bearing, and a clamping mechanism is provided at the outer end of the rotating drum 6. An outer gear ring 7 is fixedly installed on the rotating drum 6, and two pairs of the mounting seats 5 are rotatably connected to a rotating shaft 9. Two gears 10 are fixedly installed on the rotating shaft 9, and the two gears 10 are respectively meshed with the outer gear ring 7 at corresponding positions. A driving motor 8 is provided at one end of the rotating shaft 9, and the driving motor 8 is fixedly installed on a mounting seat 5. The output end of the driving motor 8 is transmission-connected to the rotating shaft 9, and an automatic welding gun 11 is fixedly installed at the rear side of the base 1.

[0020] The clamping mechanism includes an L-shaped fixing seat 12, which is fixedly welded to the outer end wall of the rotating drum 6. A bidirectional screw rod 13 is rotatably mounted on the L-shaped fixing seat 12. Two symmetrically arranged mounting rods 14 are threadedly connected to the bidirectional screw rod 13. An arc-shaped clamping block 15 is fixedly mounted on the mounting rod 14. When the bidirectional screw rod 13 is rotated in the forward direction, the two mounting rods 14 can move toward each other on the bidirectional screw rod 13, thereby driving the two arc-shaped clamping blocks 15 to move toward each other to clamp the refrigeration pipeline components.

[0021] A limiting wheel 16 is fixedly mounted on one end of the rotating rod 3 , and two symmetrically arranged slots 17 are defined on the limiting wheel 16 .

[0022] A mounting bracket 18 is fixedly welded to the top of the support rod 2 near the limiting wheel 16, and an insertion rod 19 is slidably connected to the mounting bracket 18. The insertion rod 19 is adapted to the slot 17, and the bottom end of the insertion rod 19 can be movably inserted into the corresponding slot 17, thereby limiting the limiting wheel 16 and realizing the limiting fixation of the rotating rod 3.

[0023] A positioning plate 21 is provided on one side of the outer end of the front rotating drum 6, and a vertical rod 20 is fixedly welded on the bottom wall of the positioning plate 21. The bottom end of the vertical rod 20 is fixedly welded to the base 1. The positioning plate 21 is used to position the refrigeration pipeline components when the refrigeration pipeline components are clamped, so as to facilitate keeping the welding point of the refrigeration pipeline components in the middle position of the two rotating drums 6.

[0024] Working principle: When the utility model is in use, first place a refrigeration pipeline component in the rotating drum 6 on the front side near the positioning plate 21, so that one end of it is aligned with the positioning plate 21, and then rotate the corresponding bidirectional screw rod 13 in the forward direction to make the two arc-shaped clamping blocks 15 clamp and fix the refrigeration pipeline component, and then place the other refrigeration pipeline component to be welded in the other rotating drum 6 on the front side, and make its end fit with the fixed refrigeration pipeline component end, and then clamp and fix it. After the two refrigeration pipeline components are clamped and fixed, rotate the rotating rod 3 to make the two refrigeration pipeline components flip to the position of the automatic welding gun 11 on the rear side, and then start the drive motor 8 to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the two rotating drums 6 to rotate at a uniform speed through the meshing connection of the gear 10 and the outer gear ring 7. Finally, turn on the automatic welding gun 11 for automatic welding, and automatic welding of the refrigeration pipeline components can be realized.
