Described every eccentric rod comprises an axis body and is arranged on the eccentric block of this axis body one end, and the eccentric block of two eccentric rods is symmetrically placed on the inner surface of described evaporator tube;
Described bottom surface is provided with two axis holes that are used to set the described axis body other end symmetrically with center line;
Described centering bar comprises a body of rod and is disposed on this body of rod side surface and integrated with it one a big round platform and a little round platform, this big round platform and little round platform are all concentric with the described body of rod, and described big round platform is between evaporator tube and inner sleeve, described little round platform places in the described inspection opening, is arranged with two grooves that are used to set described axis body on the periphery of this little round platform.
In above-mentioned tooling for assembling inner sleeve hole lantern ring, the external diameter of described big round platform and the internal diameter of the described collar are complementary, and the external diameter of described little round platform and the internal diameter of described inspection opening are complementary.
In above-mentioned tooling for assembling inner sleeve hole lantern ring, described bottom comprises a base plate and is arranged on this backplate surface and integrated with it cylinder that the internal diameter of this cylindrical external diameter and described inspection opening is complementary.
In above-mentioned tooling for assembling inner sleeve hole lantern ring, described eccentric block end portion thickness is greater than 3mm.
Owing to adopted above-mentioned technical solution, the centering bar that the utility model utilization part is arranged between evaporator tube and the inner sleeve, another part is positioned at inspection opening, large and small two parts external diameter by the bar of will feeling relieved is complementary with the internal diameter of the collar and inspection opening respectively, has guaranteed the concentricity of the collar and inspection opening; Simultaneously, the utility model also utilizes eccentric center principle, has designed two eccentric rods that are arranged in the inspection opening, especially to its eccentric block end portion thickness design, has guaranteed the required distance between collar bottom and the evaporator tube inner surface; In addition, characteristics such as that the utility model also has is simple in structure, easy to use, can reuse, conveniently and intactly take out after when satisfying above-mentioned two collars to adorn the specification requirement of weldering, eccentric rod and centering bar being used to complete again, thereby also have the effective characteristics that reduce of product processing cost that make.

The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
See also Fig. 2 to Fig. 7, the collar 4 ' is installed between the eyelet 5 ' of the inspection opening 3 ' of evaporator tube 1 ' and inner sleeve 2 ', the utility model, and promptly tooling for assembling inner sleeve hole lantern ring comprises two eccentric rods 1, certain core bar 2 and bottom 3, wherein:
Two eccentric rods 1 all are arranged in the inspection opening 3 ', every eccentric rod 1 comprises an axis body 11 and the eccentric block 12 that is arranged on these axis body 11 1 ends, eccentric block 12 symmetries of two eccentric rods 1 are held on the inner surface of evaporator tube 1 ', and eccentric block 12 end portion thickness are greater than 3mm;
Bottom 3 comprises a base plate 31 and is arranged on this base plate 31 surface and integrated with it cylinders 32, the external diameter of this cylinder 32 and the internal diameter of inspection opening 3 ' are complementary, and cylinder 32 surfaces are provided with two axis holes 33 that are used to set axis body 11 other ends symmetrically with center line, and axis body 11 can be connected with bottom 3 by securing member after passing axis hole 33;
Centering bar 2 comprises a body of rod 21 and is disposed on these body of rod 21 side surfaces and integrated with it one a big round platform 22 and a roundlet platform 23, big round platform 22 and roundlet platform 23 are all concentric with the body of rod 21, and big round platform 22 is positioned between evaporator tube 1 ' and the inner sleeve 2 ', the internal diameter of its external diameter and the collar 4 ' is complementary, roundlet platform 23 places in the inspection opening 3 ', the internal diameter of its external diameter and inspection opening 3 ' is complementary, and is arranged with two grooves 24 that are used to set axis body 11 on the periphery of roundlet platform 23.
