Coordinated assembly method of a separation device with three butt joints

Abstract

The invention belongs to an assembly method and particularly relates to a coordinated assembly method for a three-docking-surface separating unit. The method includes: 1, measuring the height of a cutting rope guard and positioning a cutting rope guard component on a frame; 2, piercing the frame to form holes according to bottom holes of the guard component, and expanding the holes; 3, removing the guard component; 4, tapping the frame and mounting wire thread inserts; 5, positioning a docking pipe component on the frame, mounting an expansion pipe at the position corresponding to the docking pipe component, and regulating the inserted depth of the expansion pipe to meet the design requirements; 6, fitting an expansion pipe guard, and measuring while fitting; 7, positioning and tightening the expansion pipe guard; 8, removing the guard and a flat pipe, and repeating the steps of two to four until trail assembly and tapping of the whole separating unit are finished; 9, formally mounting the cutting rope guard, the flat pipe and the expansion pipe guard; 10, re-measuring the fitting sizes of the guards, and comparing the sizes to trial assembly data; 11, mounting positioning pins and guide pins, and performing trial docking with separation related segments. The coordinated assembly method for the three-docking-surface separating unit has the advantages that the requirements on assembly strength and coordination are met and the launching needs are met.

Description

technical field [0001] The invention belongs to an assembly method, and in particular relates to a coordinated assembly method of a separation device with three butt joint surfaces. Background technique [0002] At present, there are only two docking surfaces on the separation device of general aerospace products in China, that is, it can only control the separation of two segment products, and the separation position is in the middle. The assembly of ordinary separation devices adopts traditional hole making and bolt connection methods, which may easily cause problems such as uncoordinated butt joints and inaccurate separation surfaces. And the assembling of common separation device can only guarantee one separation, is difficult to solve the difficult problem of multiple hood separations. [0003] The multi-joint surface separation device generally has three or more butt joint surfaces, and uses weakened grooves to control the separation position, such as figure 1 shown....

Problems solved by technology

Because the assembly accuracy of other separation surfaces cannot be taken into account, the existing assembly process cannot be used on this multi-butt surface separation device
