Description

Technical Field

[0001] The invention belongs to the field of carrier rocket manufacturing, and in particular relates to a multi-degree-of-freedom tooling for simulating a pipeline sampling environment on a carrier rocket. Background Art

[0002] my country's new generation of launch vehicles undertakes a series of major national scientific and technological projects such as space station construction, lunar exploration, and Mars exploration, and will face the demand for high-efficiency and high-density launches in the future. The final assembly process of the launch vehicle is to combine and assemble all related products such as tanks, shells, engines, pipelines, instruments, cables, etc. according to functional requirements and positional relationships.

[0003] As an important part of the launch vehicle, the pipeline undertakes multiple functions such as propellant transportation, tank pressurization, filling, exhaust, pressure measurement, and gas supply and distribution. It has interface relationships with multiple sections such as the tank, shell segment, and engine. The number of pipelines is huge and the boundaries are complex. There are deviations and cumulative errors in the manufacturing process of the tank, shell segment, engine and other sections. In the final assembly stage, it is necessary to compensate for the deviation of the section interface through on-site sampling of some pipelines to meet the installation requirements of the pipelines. That is, in the process of rocket final assembly, sampling production is carried out according to the actual situation of the final assembly process and the pipeline installation boundary to correct the theoretical size. This work is serial with the final assembly.

[0004] In summary, at this stage, the medium-diameter sampling pipeline (outer diameter 24mm-100mm) needs to be sampled and produced at the final assembly site. Due to the large span and multiple boundaries of the pipeline, it is often necessary for the final assembly workshop to dock 2-3 cabins before production is ready. The formal docking of multiple cabins means that the final assembly progress is nearing completion, and the production cycle of some more important medium-diameter pipelines is 21 days after sampling. There is often a situation where pipeline delivery restricts the final assembly progress, which seriously affects the final assembly cycle. Therefore, it is necessary to serialize pipeline manufacturing with the final assembly progress to reduce the pipeline's occupation cycle for final assembly. The pipeline has a variety of working conditions and shapes on the rocket body, so a tool is needed to simulate the sampling environment of the pipeline. Summary of the invention

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] In order to solve the problem that during the production process of launch vehicles, due to the large span and multiple boundaries of the pipelines, the general assembly workshop often needs to dock 2-3 cabin sections before production is ready. The formal docking of multiple cabin sections means that the general assembly progress is nearing the end, and the production cycle of some more important medium-diameter pipelines is 21 days after sampling. The pipeline delivery often restricts the general assembly progress, which seriously affects the general assembly cycle. Therefore, this application records a method of serially recording the pipeline manufacturing and general assembly progress to reduce the pipeline's occupation cycle for general assembly. This method is based on laser scanning, simulated assembly, and multi-degree-of-freedom tooling. Through laser scanning The point cloud models of the sections required for the installation of pipeline components in different parts are obtained respectively. The point cloud models of the relevant sections form the complete installation boundary of the pipeline through simulated assembly. Based on this, the multi-degree-of-freedom tooling is corrected to reproduce the pipeline assembly sampling environment, and the pipeline manufacturing timing is moved forward from the assembly stage. The pipeline production mode is changed from serial to parallel production with the assembly, which reduces the occupation of the assembly cycle. Among them, laser scanning is an existing technology, and the simulated assembly is realized by the upper computer. It is based on multi-degree-of-freedom tooling and adopts a new sampling mode of pipeline sampling environment on the tooling simulation arrow. The specific technical flow chart is as follows:

[0034] (1) Boundary simulation tooling design

[0035] During assembly, the pipeline is connected to the tank, shell and other sections. The pipeline is screwed and fastened with the tank and shell through the multi-freedom tooling on the side wall. The position accuracy of the interface directly affects whether the pipeline can be successfully installed. Based on the pipeline pre-manufacturing method of the simulation boundary, the high-precision reproduction of the pipeline interface of the tank, shell and other sections is the key. Through the multi-freedom tooling, the tank and shell side wall bracket 5 is simulated. The multi-freedom tooling can realize the adjustment of multiple degrees of freedom such as up and down, left and right, front and back, and spatial torsion, and can realize 360° correction, which can more realistically restore the installation environment on the launch vehicle.

[0036] (2) Obtaining the segment point cloud model

[0037] Handheld laser scanners can be used to scan physical objects to obtain the three-dimensional coordinates of each scanning point. With the characteristics that a large number of scanning points can form a point cloud model, after the production of individual segment products such as tanks, shell segments, and engines is completed and before delivery for final assembly, handheld laser scanners are used to scan the pipeline boundaries and segment docking surfaces in the tanks, cabins, engines, etc., and the respective point cloud models are obtained with the help of Geomagic Control X software. During the scanning, all assembly features of the segment (such as docking holes and interfaces) should be scanned in detail to ensure the accuracy of the subsequent simulated assembly.

[0038] (3) Correction of the tooling status

[0039] The multi-DOF tooling is implemented based on the local key features of the pipeline interface on the section, and all assembly features of the section (such as docking holes and docking interfaces) cannot be fully reflected. The assembly of sections is an overall docking, and all assembly features will be reflected, while the assembly of sections and tooling is a partial docking. Due to the deviation between the local and the whole, all assembly features cannot be reflected, so the installation status of the tooling needs to be corrected.

[0040] The section butt joint surface and tooling installation benchmark are both section end frames, but there are manufacturing errors in the production and installation process of the end frames, and it is impossible to make the section end frames perpendicular to the axis. In the final assembly stage, the two sections are screwed together to eliminate the end frame gap, so that the section end frames can be perpendicular to the axis. In tooling correction, the three-dimensional end frame tilt correction technology can be used to solve the problem of reference distortion caused by the angle between the section lower end frame and the axis. The three-dimensional end frame tilt correction technology refers to the technology of obtaining the section axis through the characteristic values ​​of the section annulus, reinforcement ribs, etc. in the point cloud model, calculating the end frame deviation angle, and manually correcting it in the point cloud model.

[0041] Taking the physical point cloud model of the cabin as the reference, the coordinate system is established with the end face docking hole as the origin, and the relative spatial coordinates of the bracket 5 are obtained with the help of the three-dimensional end frame correction technology. Taking the same docking hole on the end face of the tooling as the reference, the position of the tooling bracket 5 is adjusted with the help of a laser tracker. Through the adjustment of multiple degrees of freedom of the tooling, such as up and down, left and right, front and back, the unification of local and overall features is achieved, ensuring that the deviation between the installation state of the tooling and the simulation boundary is within ±0.1° and ±0.1mm. After the laser tracker is adjusted, scan the tooling according to the method in (2) to obtain the tooling point cloud model, and compare the tooling model with the physical model to verify the tooling accuracy.

[0042] (4) Simulation assembly of point cloud model

[0043] Reverse engineering (Geomagic Control X) software can analyze and process point cloud models and simulate the assembly of multiple point cloud models. According to the installation boundary of the pipeline, the reverse engineering software is used to analyze and process the relevant point cloud models of the tank, shell segment, engine, etc. Based on the common installation reference such as the installation surface and installation hole, and using the three-dimensional end frame correction technology, multiple point cloud models are simulated and assembled to obtain the simulated boundary of the pipeline installation. Considering the error caused by the tilt of the end frame, the spatial coordinate value of the tooling is obtained with the characteristic point on the segment as the origin after the simulated splicing for standby use.

[0044] (5) Assembly of sections and multi-DOF tooling

[0045] Tanks, shells, engines and other parts are usually produced in different workshops and delivered to the final assembly workshop after production. Before final assembly, different parts do not have the conditions for combined assembly. This embodiment uses a single tank, shell or engine as a carrier. After the single part is manufactured, it is combined with a multi-degree-of-freedom tooling to simulate the assembly state of multiple parts, and the multi-degree-of-freedom tooling is used to replace the parts that need to be combined and assembled.

[0046] (6) Retest of the tooling on the arrow

[0047] After the section and the tooling are assembled, considering the installation error caused by the tilt of the end frame, in order to fully verify the reliability of the multi-degree-of-freedom tooling and ensure the true and effective restoration of the installation environment on the arrow, it is necessary to conduct on-arrow re-measurement. Based on the spatial coordinate data in item (4), the state of the section and the tooling after assembly is measured by a laser tracker to ensure that the deviation between the installation state of the tooling and the simulation boundary is within ±0.1° and ±0.1mm. After completion, a laser scanner is used to obtain a point cloud model, and the physical point cloud model of the cabin section is compared and analyzed with the Geomagic Control X software to confirm the installation state of the tooling again.

[0048] (7) Pipeline manufacturing in advance

[0049] According to the reproduced pipeline installation boundary, the pipeline is manufactured under this state to ensure the distance requirements and installation status between the pipeline and the tank, shell section, engine and other sections, so as to advance the timing of pipeline production.
