[0023] As Figures 1 - 4 shown, the automotive air-conditioning pipeline production and welding tooling provided in this embodiment includes a station conversion turntable 1. Two second drive shafts 21 are rotatably connected to the station conversion turntable 1. The central axes of the two second drive shafts 21 are symmetrically distributed about the central axis of the station conversion turntable 1. One end of the second drive shaft 21 is fixedly connected to an adjustment disk 22. On the other side of the adjustment disk 22, a fixture fixing plate 31, two slide rails 41, and a telescopic cylinder 45 are fixedly connected. The two slide rails 41 are symmetrically distributed with respect to the telescopic cylinder 45. The telescopic cylinder 45 is located at a position on the side away from the fixture fixing plate 31 of the slide rail 41. A fixed fixture 32 is fixedly connected to the fixture fixing plate 31 by bolts. The first welding pipeline 100 is placed on the fixed fixture 32. An adjustment fixing plate 33 is fixedly connected to the upper surface of the fixture fixing plate 31. A first adjustment plate 34 is fixedly connected to the adjustment fixing plate 33 by bolts. Two first adjustment holes 341 are opened on the first adjustment plate 34. A finger cylinder 35 is fixedly connected to the first adjustment plate 34. Second adjustment plates 36 are fixedly connected to both output ends of the finger cylinder 35. A clamping fixture 37 is fixedly connected to the second adjustment plate 36 by bolts. Second adjustment holes 361 are opened on the second adjustment plate 36. The two clamping fixtures 37 jointly clamp the second welding pipeline 101. The fixed fixture 32 is used to fixedly support the first welding pipeline 100, and the shape can be changed according to the design requirements of the first welding pipeline 100;

[0024] A slider 42 is slidably connected to a slide rail 41. A slider connecting plate 43 is fixedly connected to the two sliders 42. An active fixture 44 is fixedly connected to the slider connecting plate 43. The opening side of the active fixture 44 is movably connected to the first welding pipeline 100. The output end of the telescopic cylinder 45 is fixedly connected to the slider connecting plate 43. By the extension of the output end of the telescopic cylinder 45, the slider connecting plate 43 is driven to move towards the first welding pipeline 100. The slider connecting plate 43 drives the active fixture 44 and the slider 42 to move on the slide rail 41 until the opening side of the active fixture 44 contacts the first welding pipeline 100. Under the action of the fixture fixing plate 31 and the fixed fixture 32, the first welding pipeline 100 is supported and fixed. By the clamping of the two output ends of the finger cylinder 35, the corresponding two second adjusting plates 36 are driven to approach each other. The two second adjusting plates 36 drive the corresponding clamping fixtures 37 to approach each other until the second welding pipeline 101 is clamped, and the second welding pipeline 101 is supported and fixed, so as to maintain the stability of the relative position between the first welding pipeline 100 and the second welding pipeline 101.

The third gear 27 drives the second transmission shaft 21 and the adjusting disc 22 to rotate, so as to adjust the welding angle between the first welding pipeline 100 and the second welding pipeline 101.

[0026] Furthermore, as shown in Figure Figure 2As shown in the figure, a first drive shaft 11 is fixedly connected to the lower surface of the work station conversion turntable 1, and a turntable support plate 51 is rotatably connected thereto. The first drive shaft 11 is located at the central axis position of the work station conversion turntable 1. An activity hole 511 is formed in the turntable support plate 51. The central axis of the activity hole 511 is collinear with the central axis of the work station conversion turntable 1. The connecting column 24 is located in the activity hole 511 and is not in contact with the activity hole 511.

The first gear 12 meshes with the fourth gear 55. The upper surfaces of the first gear 12 and the fourth gear 55 are both lower than the lower surface of the first support plate 23. By driving the fourth gear 55 to rotate with the second motor 54, the fourth gear 55 drives the first gear 12 to rotate. The first gear 12 drives the first drive shaft 11 and the work station conversion turntable 1 to rotate, change the position of the adjustment plate 22, and enable the adjustment plate 22 to be changed between the loading station and the welding station.

[0028] Even further, as Figure 1 shown in the figure, a partition plate 13 is fixedly connected to the upper surface of the work station conversion turntable 1. The two adjustment plates 22 are symmetric with respect to the partition plate 13. The partition plate 13 is used to isolate the two adjustment plates 22 and isolate the loading station and the welding station.

[0029] As Figures 1 - 4As shown in the figure, the principle of the automotive air-conditioning pipeline production welding tooling provided in this embodiment is as follows: When using the automotive air-conditioning pipeline production welding tooling, the output end of the telescopic cylinder 45 extends to drive the slider connecting plate 43 to move towards the first welding pipeline 100. The slider connecting plate 43 drives the movable fixture 44 and the slider 42 to move on the slide rail 41 until the opening side of the movable fixture 44 contacts the first welding pipeline 100. Under the action of the fixture fixing plate 31 and the fixed fixture 32, the first welding pipeline 100 is supported and fixed. The two output ends of the finger cylinder 35 clamp to drive the corresponding two second adjusting plates 36 to approach each other. The two second adjusting plates 36 drive the corresponding clamping fixtures 37 to approach each other until the second welding pipeline 101 is clamped, and the second welding pipeline 101 is supported and fixed, which can maintain the stability of the relative position of the first welding pipeline 100 and the second welding pipeline 101. Through the second adjusting holes 361 opened on the second adjusting plates 36 and the first adjusting holes 341 opened on the first adjusting plates 34, the horizontal position of the clamping fixtures 37 is adjusted so that the connection port of the second welding pipeline 101 is aligned with the first welding pipeline 100. The first motor 25 drives the second gear 26 to rotate. The second gear 26 drives the third gear 27 to rotate. The third gear 27 drives the second transmission shaft 21 and the adjusting disc 22 to rotate to adjust the welding angle of the first welding pipeline 100 and the second welding pipeline 101. The second motor 54 drives the fourth gear 55 to rotate. The fourth gear 55 drives the first gear 12 to rotate.
