Abstract
The utility model provides a tube plate and tube assembly and location tooling, relates to the field of heat exchanger fabrication and overcomes the defects of difficulty in operation, low in accuracy and efficiency and difficulty in quality guaranteeing in the prior art. The structure of the tooling comprises a table type cylinder tooling, the tooling top size phi A is slightly smaller than the size of a tube plate open pore and larger than the outer diameter of the tube, and the top height h is equal to the heat exchange tube required condensed size H. The middle size phi B is larger than the diameter of the tube plate open pore, and the lower portion size phi C is larger than phi B. By means of the tooling, the tube and tube pore concentricity can be well guaranteed; the tooling location is accurate, the requirement for the worker operation level is not high, and the technical performance is stable; the tooling is convenient to operate, the tube plate and tube assembly efficiency is greatly improved, and the work period is guaranteed; the fabrication process is simple and convenient, materials applied are common in factories and can be recycled; the tooling can be produced according to the actual size requirement and is wide in application range.
Description
Technical field
Belong to heat transmission equipment and manufacture the tube sheet in field and the assembling and positioning of pipe.
Background technology
In heat transmission equipment manufacture field, the assembling and positioning of tube sheet and heat exchanger tube has strict requirement.In recent years due to the progress of technology, equipment enlarging, complicated trend are more and more obvious, tube sheet diameter is increasing, on tube sheet, number of aperture is more and more, corresponding assembly work amount is further strengthened, especially when nuclear equipment heat exchanger is to the assembling of tube sheet and heat exchanger tube, relative position requires more strictly, has further increased degree of difficulty and the heavy degree of work.
Traditional localization method mostly is manually and locates by part, ensures the relative position of tube sheet and pipe, then fixed by survey tools such as rulers, and this method exists following shortcoming:
1, assembling is difficult, can not well ensure the concentricity of pipe and pore.
2, assembly precision is not high, affected by workman's operant level larger, difficult quality guarantee.
3, assembly work amount is heavy, particularly heat exchanger tube enormous amount, baroque equipment.
4, efficiency of assembling is low, affected by workman's proficiency larger, is difficult to ensure delivery date.
Summary of the invention
The technical problems to be solved in the utility model is the operating difficulties that overcomes above-mentioned traditional tube sheet and the existence of pipe assembly method, and precision is not high, the shortcoming of inefficiency and difficult quality guarantee.
Technical scheme is as follows:
The assembling and positioning frock of tube sheet and pipe, its structure is a table type circular cylinder frock that has multiple diameters, and frock top dimension φ A is slightly less than tube sheet bore size, and is greater than tube outer diameter, and overhead height h equates with the size H that condenses of heat exchanger tube matching requirements; Middle part size φ B is greater than tube sheet opening diameter, and lower dimension φ C is greater than φ B.
Its using method is: in the time of assembling tube sheet and pipe, and fixed tube sheet 1, frock 3 tops are stretched in tube sheet 1 hole fixing, pipe 2 is stretched into tubesheet holes from other direction and contact with frock 3 end faces, and contact-making surface laminating is closely; Adjust the gap in pipe 2 and tube sheet 1 hole, fixing tube 2; Disassembling fixture 3; Repeat above step, carry out next pore assembling.
Key problem in technology is according to the actual requirement of tube sheet and heat exchanger tube, determines the corresponding size of frock, ensures the precision of frock.
This frock has effectively been avoided the shortcoming of conventional method, has reached following technique effect:
1, in assembling docking operation, can well ensure the concentricity of pipe and pore;
2, tool locating is accurate, less demanding to personnel's operant level, and technical performance is stable;
3, easy to operate, greatly improve the efficiency of assembling, be conducive to ensure the duration;
4, manufacturing process is easy, the conventional material of Dou Shi factory of application, and can recycle;
5, can require to design and produce according to actual size, adapt to wide.
Brief description of the drawings
Fig. 1 to when assembling relative position have tube sheet and the tube construction schematic diagram of requirement.
The assembling and positioning tool structure schematic diagram of Fig. 2 tube sheet and pipe.
The assembling and positioning operation chart of Fig. 3 tube sheet and pipe.
In figure, each parts mark is as follows:
1-tube sheet 2-pipe 3-frock.
Detailed description of the invention
The structural requirement of relative position when Fig. 1 has illustrated tube sheet and pipe assembling.
Now 2 these frock makings are described by reference to the accompanying drawings: one has the table type circular cylinder of multiple diameters, and frock top dimension φ A is less than tube sheet bore size, guarantee top can be stretched in tube sheet perforate, and is greater than heat exchanger tube external diameter.Overhead height h equates with matching requirements size H, ensures the size that inside contracts when tube sheet and heat exchanger tube assemble.Middle part size φ B is greater than tube sheet opening diameter, and lower dimension φ C is greater than the stability of φ B guarantee frock.
Now by reference to the accompanying drawings 3, this frock using method is described as follows:
1, before tube sheet and heat exchanger tube assembling, fixed tube sheet, pore is stretched at frock top, and contact-making surface laminating is tight, fixing tool.
2, heat exchanger tube is stretched into pore to contacting with frock end face from other direction, contact-making surface laminating closely.
3, adjust the gap of heat exchanger tube and pore, fixing heat exchanger tube.
4, disassembling fixture.
5, repeat above step, carry out next pore assembling.
This frock is applicable to any one tube sheet and connects multiple pipes and the strict manufacture processing of positioning requirements.
