s300, determining the spatial position of the first cabin bracket according to the first positioning mark of the standard sample tube, and determining the spatial position of the second cabin bracket according to the second positioning mark;
s400, taking down the standard sample pipe, arranging the first cabin section bracket on the inner wall of the cabin section according to the spatial position of the first cabin section bracket, and arranging the second cabin section bracket on the inner wall of the cabin section according to the spatial position of the second cabin section bracket;
s500, correcting the spatial positions of the first cabin section bracket and the second cabin section bracket;
s600, after a formal pipeline is obtained according to the three-dimensional model production of the standard sample pipe, the formal pipeline is assembled on a first cabin section support and a second cabin section support of the cabin section inner wall.
According to the cabin section pipeline assembling method, the three-dimensional model diagram of the space carrier cabin section is utilized, the first positioning mark, the second positioning mark and the reference mark are sequentially formed on the outer wall of the pipeline of the standard pipeline according to the position relation between the support and the pipeline in the diagram, the circumferential mark is formed at the corresponding position of the reference plate according to the position relation between the starting end of the standard pipeline and the reference plate, and the circumferential mark is used for determining the circumferential position of the standard sample pipe. The first positioning mark, the second positioning mark, the reference mark, and the circumferential mark of the reference plate may be marked by a processing device according to a set position in the three-dimensional model, and may be marked by a scribing method by the processing device. Specifically, the first positioning mark and the second positioning mark are mark lines arranged along the circumferential direction of the standard sample tube, and the reference mark comprises the mark lines arranged along the circumferential direction of the standard sample tube and also comprises mark lines matched with the circumferential mark of the reference plate and arranged along the axial direction of the standard sample tube. According to the two marking lines arranged in the way of the reference mark, the axial and circumferential positions of the standard sample tube and the reference plate after being spliced can be accurately determined. The axial marking line is used for determining the circumferential position of the standard sample pipe in the cabin section.
The reference plate is used as a reference for assembling the cabin section pipeline and is usually arranged on the bottom heat-proof plate at the lowest end of the cabin section, the position of the reference plate can be accurately positioned in the processing process of the bottom heat-proof plate, and the fixed position of the reference plate is reserved. Before the standard sample tube is assembled, the reference plate is fixedly arranged at the reserved position, the standard sample tube with the mark is inserted into the reference plate, wherein the part of the standard sample tube inserted into the reference plate can be vertical to the other part, the standard sample tube can also be understood as being arranged in an L shape, and the shorter part of the pipeline is used for inserting the reference plate, so that the standard sample tube is convenient to fix and position.
When the connection relation between the standard sample tube and the reference plate is adjusted, the circumferential marking line of the reference mark is observed firstly, when the circumferential marking line is adjusted in place, the axial position of the standard sample tube is determined, then the standard sample tube rotates in the reference plate, and when the axial marking line of the reference mark is aligned with the positioning mark of the reference plate, the circumferential position of the standard sample tube is also determined. In the current state, the distance from the standard sample pipe to the inner wall of the cabin section is just the same as the supporting height of the cabin section bracket (namely the distance from the end of the bracket contacting the inner wall of the cabin section to the surface of the bracket for supporting the pipeline). Further, when the distance from the standard sample tube to the inner wall of the cabin section is not completely the same as the supporting height of the cabin section support (within an allowable error), the standard sample tube can be filled by arranging soft materials such as felt on the supporting end face of the support, so that accurate positioning and assembly of the standard sample tube are ensured. And then, determining the axial position of the first cabin section support according to the first positioning mark of the standard sample pipe, marking the axial position of the first cabin section support on the circumferential position of the inner wall of the cabin section according to the appearance and the size of the standard sample pipe, and repeating the steps to mark the axial position and the circumferential position of the second cabin section support after the spatial positions of the first cabin section support are completely marked. In the current step, the circumferential position of the cabin section bracket is roughly determined, so that the subsequent correction step can be facilitated, and the correction efficiency is improved.

In order to ensure the position accuracy of the cabin section support, the circumferential position of the cabin section support can be determined again through the correction step, and the first cabin section support and the second cabin section support are ensured to be accurately arranged at proper positions of the inner wall of the cabin section.
And after the cabin section support is assembled, assembling a formal pipeline which has the same specification and size as the standard pipeline and is produced in the same way as the standard pipeline on the cabin section support to complete the assembly. According to the cabin section pipeline assembling method, the standard sample pipe and the reference plate are subjected to positioning marking in advance according to the three-dimensional model, and the cabin section support is accurately positioned and assembled according to the positioning marking of the standard sample pipe, so that the assembling error of the cabin section pipeline and the cabin section support is greatly reduced, the cabin section pipeline matched with the cabin section support does not need to be separately produced according to the trend of the cabin section support, the final assembly period of the spacecraft carrier is ensured, the rejection rate of pipeline products is reduced, the final assembly process is further optimized, and the consistency and interchangeability of the pipeline products and the spacecraft carrier products are improved.
Further, the reference plate is fixedly arranged at the reserved position, after the standard sample tube is inserted into the reference plate, the standard sample tube is adjusted to enable the reference mark of the standard sample tube to be matched with the positioning mark of the reference plate to the corresponding position, and the method for determining the axial position and the circumferential position of the standard sample tube comprises the following steps:
and adjusting the standard sample tube, namely observing the circumferential marking line of the reference mark, determining the axial position of the standard sample tube after the circumferential marking in the reference mark of the standard sample tube is matched with the reference plate in place, and then adjusting the standard sample tube to rotate in the circumferential direction in the reference plate to align the axial marking line of the reference mark of the standard sample tube with the circumferential marking of the reference plate so as to determine the circumferential position relation between the standard sample tube and the reference plate.
The reference mark of the standard sample tube and the circumferential mark of the reference plate are marked by scribing with processing equipment according to the set position in the three-dimensional model, and the marking method is convenient to operate and easy to realize.
According to the cabin section pipeline assembling method, after the circumferential marking line of the reference mark of the standard sample pipe is matched with the reference plate in place, the axial position of the standard sample pipe can be determined, then the standard sample pipe is rotated in the circumferential direction in the reference plate, so that the circumferential position relation between the standard sample pipe and the reference plate is obtained after the axial marking line of the reference mark is matched with the circumferential marking of the reference plate, the method is simple and convenient to operate, high in precision and capable of rapidly determining the spatial position of the standard pipeline.
Furthermore, the circumferential marking line and the axial marking line of the reference mark of the standard sample tube can accurately position the standard sample tube, when the standard sample tube is assembled again for correction, the spatial position of the standard sample tube can be accurately and quickly determined through the reference mark and the circumferential marking, and then the subsequent correction step is carried out, so that the correction efficiency of the cabin section support can be improved while the correction precision is ensured.
In the above embodiment, the method of correcting the spatial positions of the first and second deck brackets is:

overlapping the standard sample pipe with the first cabin section support, matching the standard sample pipe with the first cabin section support, correcting the circumferential position of the first cabin section support according to a matching result, and fixing;
and overlapping the standard sample pipe with the second cabin section support, matching the standard sample pipe with the second cabin section support, and fixing after correcting the circumferential position of the second cabin section support according to a matching result.

Further, according to the position of the cabin bracket in the three-dimensional model of the cabin of the spacecraft, the method for forming at least the first positioning mark, the second positioning mark and the reference mark on the standard sample tube comprises the following steps:
and determining a reference mark of the standard sample tube according to the supporting height of the cabin section support in the three-dimensional model, and ensuring that the distance between the pipeline and the inner wall of the cabin section is equal to the supporting height of the cabin section support after the standard sample tube and the reference plate are assembled in place. It should be noted that the reference mark to be determined in this embodiment refers to a circumferential mark line for determining the axial position of the master sample tube. For example, the reference plate and the cabin bracket are arranged in the same plane, the support height of the cabin bracket is measured to be h1, and then a reference mark is added at the position, away from the inflection point h1, of the short-side pipeline of the L-shaped pipeline, so that the adaptation process of the standard sample pipe can be ensured, and the precision requirement of assembling the cabin bracket and the pipeline can be accurately met.
And determining each positioning point of the standard sample tube according to the supporting positions of the cabin bracket and the pipeline in the three-dimensional model, and at least sequentially forming a first positioning mark and a second positioning mark. The first positioning mark, the second positioning mark, and the reference mark may be marked by a processing device according to a set position in the three-dimensional model, or may be marked by a reticle marking device.

Further, the method for determining the spatial position of the first cabin bracket according to the first positioning mark of the standard sample tube and the spatial position of the second cabin bracket according to the second positioning mark comprises the following steps: after the standard of the standard sample tube is determined, the positions of the corresponding cabin section supports can be sequentially confirmed according to the positioning marks of the standard sample tube, and auxiliary marks are carried out on the inner wall of the cabin section, so that the cabin section supports can be accurately assembled in place according to the auxiliary marks after the standard sample tube is detached.
Specifically, the circumferential position and the axial position of the first cabin section support in the cabin section are determined according to the first positioning mark of the standard sample tube, and an auxiliary mark is added on the inner wall of the cabin section. The auxiliary markers can be simultaneously marked along both sides of the master tube with the first positioning markers using a swabable marker, ensuring that both the axial and circumferential positions of the capsule support can be determined simultaneously. Similarly, the circumferential position and the axial position of the second cabin section bracket in the cabin section are determined according to the second positioning mark of the standard sample pipe, and an auxiliary mark is added on the inner wall of the cabin section.
Further, in order to facilitate the fixing of the cabin section brackets and the cabin sections, the first cabin section bracket may be disposed on the inner wall of the cabin section according to the spatial position of the first cabin section bracket, and the method for disposing the second cabin section bracket on the inner wall of the cabin section according to the spatial position of the second cabin section bracket may be:
