Description
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 get into should the 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 said collar is installed between the eyelet of inspection opening and inner sleeve of evaporator tube; Described frock comprises certain core bar, be arranged on the bottom that two eccentric rods and in the said inspection opening are connected with two eccentric rods
Said every eccentric rod comprises an axis body and the eccentric block that is arranged on this axis body one end, and the eccentric block of two eccentric rods is symmetrically placed on the inner surface of said evaporator tube;
Said bottom surface is provided with two axis holes that are used to set the said axis body other end symmetrically with center line;
Said centering bar comprises a body of rod and is arranged on this body of rod side surface and integrated with it one a big round platform and a little round platform at interval; This big round platform and little round platform are all concentric with the said body of rod; And said big round platform is between evaporator tube and inner sleeve; Said little round platform places in the said inspection opening, is arranged with two grooves that are used to set said 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 said big round platform and the internal diameter of the said collar are complementary, and the external diameter of said little round platform and the internal diameter of said inspection opening are complementary.
In above-mentioned tooling for assembling inner sleeve hole lantern ring, said 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 said inspection opening is complementary.
In above-mentioned tooling for assembling inner sleeve hole lantern ring, said 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 through 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 characteristics that the product processing cost is effectively reduced.

The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the present invention is elaborated.
See also Fig. 2 to Fig. 7, the collar 4 ' is installed between the eyelet 5 ' of inspection opening 3 ' and inner sleeve 2 ' of evaporator tube 1 ', 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;
Centering bar 2 comprises a body of rod 21 and is arranged on these body of rod 21 side surfaces and integrated with it one a big round platform 22 and a roundlet platform 23 at interval; Big round platform 22 is all concentric with the body of rod 21 with roundlet platform 23; And big round platform 22 is positioned between evaporator tube 1 ' and the inner sleeve 2 ', and the internal diameter of its external diameter and the collar 4 ' is complementary, and 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 ', get into, 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 greater than 3mm, therefore, can guarantee that the bottom of the collar 4 ' and the inner surface of evaporator tube 1 ' have the gap greater than 3mm; Again because the internal diameter of the collar 4 ' is consistent with the external diameter of big round platform 22, 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 internal diameter and inspection opening 3 ' of the collar 4 ' concentric at this moment.
More than combine accompanying drawing embodiment that the present invention is specified, those skilled in the art can make the many variations example to the present invention according to above-mentioned explanation.Thereby some details among the embodiment should not constitute qualification of the present invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
