Abstract
A folding type triple clamp structure is characterized by comprising an upper-half portion of a clamp, a lower-half portion of the clamp, flat taper semi-tubular rivets, a size A, a size B, a size phi C, a size phi D and a size phi E. The upper-half portion of the clamp and the lower-half portion of the clamp are connected through the flat taper semi-tubular rivets, and then combined into a whole in flaring and riveting mode. The value of a surface division angle F of a folding portion between the upper-half portion of the clamp and the lower-half portion of the clamp is 32degrees-34degrees, the value of thickness is 14 millimeters, the folding portion is 7 millimeters in thickness, the upper-half portion of the clamp is provided with a through hole of phi 6.5 millimeters, and the lower-half portion of the clamp is provided with a M6 thread through hole. The folding type triple clamp structure has the advantages of improving assembly of an aircraft engine pipeline and consistency of a pipeline state, improving conditions that results of pipeline dynamic stress measurement are large in dispersion degrees, and enabling fixing and matching of the pipeline to be tight by the means of the reasonable surface division angle of the folding portion. Three circular holes are different in slotting sizes, and therefore repeated locations are avoided. The folding type triple clamp structure is fewer in the number of parts, light in weight and good in assembly.
Description
Technical field
The present invention relates to the aeroengine field, a kind of folding paper three yoke configurations are provided especially.
Background technique
Modern aeroengine comprises systems such as fuel oil, lubricating oil, cooling, control, startup, and these systems comprise a large amount of pipelines and cable, and motor is carried out fuel feeding, lubricated, ventilation, control and hydraulic transmission.Usually; A typical aeroengine has 100-250 root exterior line; The mounting point is limited in the space limited between engine crankcase and the aircraft nacelle, therefore needs to consider pipeline trend, pipeline gap, pipeline stress, engine luggine, productibility, maintainability or the like a series of problems.
When present domestic engine pipelines lays; All adopt " parallel principle " to carry out the pipeline laying moulding; With the technology that reaches pipeline and the combination of aesthetic requirement, therefore three, four situation that pipeline lays side by side occur, but generally all adopt the means of fixation of single deck tape-recorder hoop and two clip combine and assemble through regular meeting; Especially two clip quantity are more, increased workload for virtually collection part, assembler, part management.With three tube banks side by side is example, and not only assembly precision is not high relatively to adopt a large amount of two clips, and the location is inaccurate.Because pipeline state inconsistent, the accuracy of comparative analysis as a result that causes the pipeline dynamic stress to be measured is poor, and dispersion degree is bigger, is not easy to the later stage to carry out well designed targetedly.Therefore the tube bank that needs a kind of novel three yoke configurations of design to be used for laying is side by side fixed, to improve the assembling of pipeline.
To above present situation, need a kind of novel folding paper three yoke configurations of design, when reducing number of spare parts, improve the assembling and the general assembly efficient of pipeline.
Summary of the invention
The objective of the invention is assembling and general assembly efficient, a kind of folding paper three yoke configurations are provided especially in order to improve pipeline.
The invention provides a kind of folding paper three yoke configurations, it is characterized in that: comprise the clip first half 1, clip Lower Half 2, flat taper head socket shank rivet 3, size A4, size B5, size φ C6, size φ D7, size φ E8.
In novel folding paper three yoke configurations, the F recommendation is 32 ° ~ 34 ° at the branch face angle of folding place for the clip first half 1, clip Lower Half 2.
In novel folding paper three yoke configurations, the thickness recommendation of the clip first half 1, clip Lower Half 2 is 14 mm, and folding place thickness is 7mm.
In novel folding paper three yoke configurations, it is 2 mm ~ 3 mm that size φ D7, size φ E8 place circular hole crack apart from recommendation, and it is 0.5mm ~ 1mm that φ C6 circular hole cracks apart from recommendation.
In novel folding paper three yoke configurations, flat taper head socket shank rivet 3 is connected back enlarging riveted joint with the clip first half 1 with clip Lower Half 2.
In novel folding paper three yoke configurations, the clip first half 1, clip Lower Half 2 profiles recommend from the folding hole cylindrical to the tangent transition of clip cylindrical.
In novel folding paper three yoke configurations,, can satisfy the pipeline of different tube diameters and fix through adjustment hoop component internal diameter size φ C6, φ D7, φ E8;
In novel folding paper three yoke configurations, should be through retaining carpenters square cun A4, the size B5 of clip greater than the maximum gabarit of different tube diameters pipeline connecting parts, the gap of assurance pipeline.
In novel folding paper three yoke configurations, the clip first half 1 has φ 6.5 mm through holes, clip Lower Half 2 has the M6 tapped through hole.
Described
Size and branch face angle value are preferably following two groups of data:
| A | B | ΦC | ΦD | ΦE | F |
| 33mm | 20mm | 16mm | 16mm | 8mm | 33° |
| 33mm | 20mm | 16mm | 16mm | 16mm | 33° |
Advantage of the present invention: for the assembling of raising aeroengine pipeline and the conformity of pipeline state, improve the big situation of dispersion degree as a result that the pipeline dynamic stress is measured, design a kind of folding paper three yoke configurations.This structure adopts the Fen Mianjiao of rational folding place, makes the pipeline secure fit tight; The three circular holes size difference of cracking avoids locating repetition.This constitutional detail quantity is few, and weight is lighter, has assembling preferably.
