TECHNICAL FIELD
[01] The present disclosure is mainly applied to the technical field of aerospace assembly and manufacturing, and particularly relates to a digital assembly and manufacturing method for a flame exhaust pipe of a servo mechanism.

EXHAUST PIPE OF SERVO MECHANISM
TECHNICAL FIELD
[01] The present disclosure is mainly applied to the technical field of aerospace assembly and manufacturing, and particularly relates to a digital assembly and manufacturing method for a flame exhaust pipe of a servo mechanism.
BACKGROUND ART
[02] A flame exhaust pipe of a servo mechanism is an important component of an aircraft pipeline system. Its working environment is mainly influenced by high temperature, high pressure, vibration and other comprehensive environmental factors.
Connection strength reduction, sealing performance weakening, structural characteristic change, etc. of pipelines will directly influence normal operation of the whole pipeline system and the servo mechanism.
Connection strength reduction, sealing performance weakening, structural characteristic change, etc. of pipelines will directly influence normal operation of the whole pipeline system and the servo mechanism.
[03] At present, this kind of flame exhaust pipes are still assembled and manufactured in a manufacturing mode of serial production and field sampling. The method has common problems of a low degree of digitization and poor adaptability to assembly boundary conditions. The problems mainly includes the following aspects:
[04] 0 During pipeline manufacturing, parallel production cannot be achieved.
In an existing mode, flame exhaust pipes must be sampled in a final assembly site of a workshop, and the sampling must be conducted after assembly and butt-joint of an engine and a tail section, which greatly increases waiting time for final assembly of products.
In an existing mode, flame exhaust pipes must be sampled in a final assembly site of a workshop, and the sampling must be conducted after assembly and butt-joint of an engine and a tail section, which greatly increases waiting time for final assembly of products.
[05] 0 During pipeline assembly, boundary conditions are highly dependent on actual products. Every time, 2-3 people need to work together and transport welding machines, tools, instruments and other materials from a manufacturing workshop to the final assembly site, and complete repair, spot welding, trial assembly and other processes on the basis of the actual products on the site, resulting in conflict and waste of a certain amount of time, manpower and resources.
[06] 0 An artificial experience requirement is high and repair time is long.
The flame exhaust pipes have no compensation functions, which greatly increases the difficulty of on-site repair. Minor repair of a coordination section may lead to a large inclination angle at an end of a pipeline. At present, filing is completely dependent on artificial experience, which is labor intensive, requires high experience and takes a long time. It takes at least 2 hours for an experienced technician to file a product.

Digital measurement and assembly coordination technologies are used to simulate actual assembly spaces of boundaries of two ends of the flame exhaust pipe, a digital coordination model based on pipeline assembly is established, selection and assembly of a pipeline coordination section in a digital virtual space are proposed, Date Recue/Date Received 2022-12-16 pipeline laser cutting is conducted with digital coordination parameters as the basis of manufacturing in a whole process, and finally digital manufacturing of the flame exhaust pipe is achieved, such that assembly and production efficiency is greatly improved, and assembly waiting time is shortened.
[08] The present disclosure solves the technical problems through the technical solution as follows: a digital assembly and manufacturing method for a flame exhaust pipe of a servo mechanism includes the following steps:
[09] step one, using a laser tracker to create a measurement coordinate system V1XYZ for a butt-joint face between a horizontally-placed engine and a tail section, and then measuring an outer circle of a servo mechanism pipe mouth, the outer circle being represented by a proxy model circle Q1 in a vector form;
[10] step two, using the laser tracker to create a measurement coordinate system V2XYZ for a butt-joint face between a vertically-placed tail section and an engine, and then measuring a tail section flame exhaust pipe mouth inner side face and arc, the inner side face and arc being represented by a proxy model circle Q2 in a vector form;
[11] step three, converting measurement data of step one and step two to three-dimensional models separately, conducting digital virtual assembly, and aligning the measurement coordinate system V1XYZ with the measurement coordinate system V2XYZ, so as to obtain boundary conditions of two ends of the flame exhaust pipe;
[12] step four, assembling a flame exhaust pipe joint and a transition pipe on the proxy model circle Q 1, so as to obtain a proxy model circle Q3 of a tail end of the transition pipe;
[13] step five, importing a pipe to be repaired into a digital assembly coordination model, assembling a long end of the pipe at a tail section flame exhaust pipe mouth, and ensuring that a central axis passes a center of the proxy model circle Q2, and that a central axis of a short end of the other side of the pipe passes a center of the proxy model circle Q3 of the tail end of the transition pipe;
[14] step six, adjusting the pipe to an appropriate position in the digital assembly coordination model, and ensuring that the short end overlaps the transition pipe moderately, the long end may extend out of a wall face of the tail section, and a required clearance value is reached;
[15] step seven, coordinating the pipe and the transition pipe in the digital assembly coordination model, so as to obtain a pipe after virtual cutting and size parameters of the pipe; and
[16] step eight, importing the size parameters of the pipe after virtual cutting into a three-dimensional laser machine, conducting laser cutting on an actual pipe, and finally welding the actual pipe after laser cutting to an actual pipe joint and an actual transition pipe, so as to complete digital assembly and manufacturing of the flame exhaust pipe.
[17] Compared with the prior art, the present disclosure has the beneficial effects:
[18] (1) The present disclosure uses a manufacturing mode of parallel production and may shorten manufacturing time of the flame exhaust pipe, and pipeline assembly may be conduced after final assembly and butt-joint, such that waiting time of final assembly is obviously shortened.
[19] (2) The present disclosure uses measurement devices, such as the laser tracker, to Date Recue/Date Received 2022-12-16 measure a size of a product, which has high measuring accuracy, such that product feature information may be quickly and accurately reflected, and digital manufacturing accuracy of the product is improved.
[20] (3) The present disclosure omits a process of on-site repair, spot welding and trial assembly by an operator, thus avoiding conflict and waste of a certain time, manpower and resources.
[21] (4) According to the present disclosure, production is conducted with the measurement data as the basis of a manufacturing process, such that long time consumption and high labor intensity caused by over-reliance on artificial experience during production are prevented, and in addition, a digital manufacturing degree of products is improved, and production efficiency of products is increased.
[22] The present disclosure solves a problem that pipeline assembly in the aerospace field is highly dependent on on-site filing, and has characteristics of accurate measurement, data control, strong operability, high efficiency and economy, etc. The method has higher popularization and practical value compared with similar methods, may generate high economic value after extensive popularization and application, and has a good reference function in the field of sectional pipeline connection and assembly.
