Among them, the rounding process has a crucial impact on the quality of the evaporation tank. In order to ensure the roundness of the cylinder, the main methods of the existing rounding steps are: adjusting the roundness by machining the entire cylinder after welding, or by selecting thicker cylinder materials when selecting materials to ensure the roundness of the cylinder after welding; however, the machining method requires the configuration of corresponding rounding equipment, which is not only complicated to operate, but also has low rounding efficiency, while the method of selecting thicker materials is costly and wastes materials.
[0003] Therefore, it is necessary to design a evaporator cylinder welding anti-deformation mechanism to solve the above problems. Utility Model Content

[0006] As a further improved technical solution of the utility model, the number of the limit posts is four, the four limit posts are arranged on both sides of the opening of the expansion ring, and the guide grooves are matched with the limit posts in a one-to-one correspondence.
[0007] As a further improved technical solution of the utility model, a limiting block is provided at the end of the limiting column to prevent the limiting plate from falling off.
[0008] As a further improved technical solution of the utility model, the limiting plate is U-shaped, and the guide grooves are provided on two arms of the U-shaped limiting plate.
[0009] As a further improved technical solution of the utility model, it also includes a wedge-shaped pad, and the wedge-shaped pad is arranged at the opening of the expansion ring.
[0010] As a further improved technical solution of the utility model, the radial width of the expansion ring is 50-100 mm, and the axial thickness of the expansion ring is 20-40 mm.
[0011] As a further improved technical solution of the utility model, the inner diameter of the expansion ring is 500-800 mm, and the opening distance of the expansion ring is 15-30 mm.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Please refer to Figure 1 and Figure 2 As shown, the utility model provides an anti-deformation mechanism for welding a cylinder of an evaporator, which includes an expansion ring 10, a limit assembly 30, an expansion assembly 20 and a wedge-shaped cushion block 40.
[0017] The expansion ring 10 is a circular ring with an opening, and the opening distance is 15-30mm, which refers to the shortest distance at the opening of the expansion ring 10 in a natural state (a state not restricted or expanded by the expansion assembly 20). The radial width of the expansion ring 10 is 50-100mm, the axial thickness of the expansion ring 10 is 20-40mm, and its inner diameter is 500-800mm. Therefore, the evaporator cylinder welding anti-deformation mechanism in this embodiment can be applied to cylinders with larger inner diameters. In other embodiments, the dimensions of the expansion ring can be designed according to actual needs to adapt to cylinders of different sizes.
[0018] The expansion assembly 20 is arranged on one side of the axial direction of the expansion ring 10, and is used to adjust the opening size of the expansion ring 10, and further change the outer diameter of the expansion ring 10. The expansion assembly 20 includes a bidirectional screw 22 and fixed plates 21 fixed on both sides of the opening of the expansion ring 10. The fixed plates 21 are respectively matched with the threads at both ends of the bidirectional screw 22. When the bidirectional screw 22 rotates, since the threads at both ends thereof are in opposite directions, the movement directions of the two fixed plates 21 are opposite, so the opening of the expansion ring 10 is reduced or expanded under the drive of the fixed plates 21. With such a configuration, the outer diameter of the expansion ring 10 can be reduced or expanded under the action of the expansion assembly 20.
[0019] The limit assembly 30 is arranged on one axial side of the expansion ring 10 (the side opposite to the tightening assembly 20), and is used to limit the movement direction of the two ends of the opening of the expansion ring 10 during the adjustment of the tightening assembly 20, and can also reduce the lateral force of the bidirectional screw 22, so that the adjustment is smoother. The limit assembly 30 includes a limit column 32 and a limit plate 31, and the limit column 32 is axially fixed to both sides of the opening of the expansion ring 10. In this embodiment, the number of the limit columns is four, and the four limit columns 32 are arranged in pairs on both sides of the opening of the expansion ring 10. The end of the limit column is provided with a limit block to prevent the limit plate from falling off. The limiting plate 31 is provided with a guide groove 311 that cooperates with the limiting column 32. The guide groove 311 corresponds to the limiting column 32 one by one. The limiting plate 31 is U-shaped. The guide groove 311 is opened on the two arms of the U-shaped limiting plate 31. The guide grooves 311 on the same side of the opening are arranged side by side, and the guide grooves 311 on both sides of the opening are arranged facing each other.
[0020] The wedge-shaped pad 40 is arranged at the opening of the expansion ring 10. When the expansion assembly 20 is adjusted, the wedge-shaped pad 40 is placed at the opening of the expansion ring 10, which can reduce the stress on the expansion assembly 20 and the limit assembly 30, prevent the evaporator cylinder welding anti-deformation mechanism from deforming, and extend the service life of the mechanism.
[0021] In summary, the evaporator cylinder welding anti-deformation mechanism of the utility model can effectively prevent the deformation of the cylinder during welding by adopting an expansion assembly and a limit assembly, thereby effectively improving the roundness quality of the evaporator; compared with the traditional machining method for adjusting the roundness, the utility model does not need to be configured with corresponding rounding equipment, is easy to operate, and can greatly improve the rounding efficiency; a thinner cylinder material can be selected when selecting materials, instead of selecting a thicker material to ensure the roundness after welding, thereby reducing material costs and reducing material waste; the coordinated design of the expansion ring, the limit assembly and the expansion assembly enables it to adapt to evaporator tanks of different sizes and shapes, and has strong versatility.
