Positioning buffering device suitable for spacecraft pipeline assembling

Abstract

The invention discloses a positioning buffering device suitable for spacecraft pipeline assembling, and relates to a buffering positioning device. The positioning buffering device comprises a base, a guide block, a traction mechanism, an adjustment screw, a buffering spring, a photoelectric switch and a shading sheet, wherein the base is fixedly connected with an external driving device; the guide block is inserted into the base and is in clearance fit with the side wall of the base; the base drives the guide block to move through the traction mechanism, and the base and the guide block relatively move in the height direction; the external driving device drives the base to move; the base drives the guide block and a multi-dimensional combined table to move; when the bottom of the multi-dimensional combined table is positioned on a target horizontal panel, the guide block stops downwards moving in the height direction, and the base continues to downwards move along the height direction relative to the guide block until the shading sheet shades the photoelectric switch; the photoelectric switch generates a stop signal and sends the signal to the external driving device to enable the base to stop downwards moving, so that positioning is finished. According to the positioning buffering device, the assembling precision and the efficiency are improved; the reliable positioning effect in a pipeline assembling process is effectively achieved.

Description

technical field [0001] The invention relates to a buffer positioning device. Background technique [0002] In recent years, with the increasing number of space vehicle development and space launch tasks, it is increasingly urgent to shorten the space vehicle assembly development cycle, and pipeline assembly has become one of the main bottlenecks in space vehicle development. The development of traditional satellite whole-satellite pipelines and manned spacecraft pipelines must carry out pipeline sampling, production, trial assembly and corresponding processing when the star / cabin, equipment, and instruments are in place at the final assembly stage, which takes up the final assembly cycle and Restricted by the availability of equipment and instruments, it can be said that the pipeline assembly cycle directly affects the star / ship final assembly cycle. [0003] With the continuous development of aerospace technology, the pipeline structure of spacecraft is becoming more and m...

Problems solved by technology

[0004] However, the internal program setting of the drive device is completely calculated based on theoretical values, and there is an error with the actual assembly, which cannot guarantee the accuracy and reliability of the assembly

For example, there is a certain error in the dimensions of the multi-dimensional combination table during the manufacturing and assembly process. If the size is smaller than the theoretical size, when the drive device puts the multi-dimensional combination table on the assembly platform according to the theoretical size, there will be a gap between the multi-dimensional combination table and the assembly platform. There is a gap, and the accuracy will be greatly affected when the multi-dimensional combination table is fixed on the assembly platform; if the outer dimension of the multi-dimensional combination table is larger than the theoretical size, the driving device will collide when the multi-dimensional combination table is placed on the assembly platform, which will affect the entire system.
