Technical field
The present invention relates to a kind of tooling for assembling inner sleeve hole lantern ring.
Background technology
As shown in Figure 1, in the assembly of the bottom of evaporimeter band sleeve, need between evaporator tube 1 ' and inner sleeve 2 ', adorn the collar 4 ' of a cylindrical shell inspection opening 3 ' of weldering usually, and the inside diameter D 2 of inspection opening 3 ' is less than the inside diameter D 1 of the collar 4 '; The dress weldering of the collar 4 ' needs to guarantee two specification requirements: one, the distance L between the inner surface of the bottom of the collar 4 ' and evaporator tube 1 ' must guarantee greater than 3mm; Two, the collar 4 ' must guarantee certain concentricity with inspection opening 3 '.Because the zone between evaporator tube 1 ' and the inner sleeve 2 ' is a very thin narrow cylindrical region 5 ', operating personnel's hand or health all can't enter this zone, therefore, just need to use a kind of auxiliary equipment to realize the purpose of the dress weldering collar 4 ', and satisfy above-mentioned two specification requirements.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the present invention aims to provide a kind of tooling for assembling inner sleeve hole lantern ring, does not destroy frock to be implemented in, and does not also damage under the prerequisite of product the purpose of the assembling collar.
A kind of tooling for assembling inner sleeve hole lantern ring of the present invention, the described collar is installed between the eyelet of the inspection opening of evaporator tube and inner sleeve, described frock comprises certain core bar, be arranged on two eccentric rods and a bottom that is connected with two eccentric rods in the described inspection opening
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 present invention utilizes the centering bar that a 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 present invention 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 present invention 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 embodiments of the invention are 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 present invention, 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.
The present invention in use, at first make eccentric rod 1 when 0 spends, from the inspection opening 3 ' of evaporator tube 1 ', enter, again with eccentric rod 1 Rotate 180 degree, make eccentric block 12 ride on the evaporator tube 1 ' inwall that (eccentric distance that notes eccentric rod 1 should be controlled in the inspection opening 3 ' inside diameter ranges of coming in and going out, with the requirement that can take out eccentric rod 1 after satisfy using), then bottom 3 is stretched in the inspection opening 3 ', and fixing eccentric rod 1; At this moment, the bar 2 of will feeling relieved is packed into from the eyelet 5 ' of inner sleeve 2 ', makes big round platform 22 be shelved on eccentric block 12 surfaces, and roundlet platform 23 is embedded in the inspection opening 3 ', and this moment, frock installed; At last, the collar 4 ' is packed into from the eyelet 5 ' of inner sleeve 2 ' get final product; At this moment, the collar 4 ' is enclosed within outside the big round platform 22, and the bottom of the collar 4 ' contacts with the end of eccentric block 12, because eccentric block 12 end portion thickness are greater than 3mm, therefore, the inner surface that can guarantee the bottom of the collar 4 ' and evaporator tube 1 ' has the gap greater than 3mm; Again because the external diameter of the internal diameter of the collar 4 ' and big round platform 22 is consistent, and the external diameter of roundlet platform 23 is consistent with the internal diameter of inspection opening 3 ' again, just can keep the internal diameter of the internal diameter of the collar 4 ' and inspection opening 3 ' concentric at this moment.
Below embodiment has been described in detail the present invention in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
