Embodiment Construction

[0037] At present, in the assembly process, special tooling is used to clamp the shell lug 32 to ensure that the small solid rocket does not rotate when torque is applied. The number of clamping tooling for the small solid rocket is not only related to the radius of the shell 31, but also related to the size (length) of the lug. , width), resulting in a large number of tooling, and almost every product requires a tooling; in order to reduce the number of tooling, the use of solid small rocket shells is cylindrical, and the method of directly clamping the cylindrical shell is used. Holds solid small rockets.

[0038] see Figure 7 , the solid small rocket automatic assembly device includes: a clamping tool 62, a tightening shaft 63, a tightening tool 64, a base and a control device 65;

Abstract

The invention discloses an automatic assembling device and method for a small solid rocket. The assembling device comprises a clamping tool, a tightening shaft, a tightening tool, a base and a control device. The clamping tool comprises a fixed part and a movable part and can clamp the small solid rocket. The semi-cylindrical curved surfaces of the fixed part and the movable part are made of antiskid materials with the pasting and friction coefficient of [0.3,0.5]. The tightening shaft comprises a drive mechanism and an output shaft. The drive mechanism outputs the assigned torque to drive the output shaft to rotate. A hexagonal part of a spray pipe of the small solid rocket is tightened through the hexagonal tightening tool. In the assembling process, the opening part of the hexagonal tightening tool is clamped on the hexagonal part of the spray pipe of the small solid rocket, the tightening shaft runs downwards, the output shaft is inserted in the connector part of the tightening tool, and the drive mechanism outputs the assigned torque to drive the output shaft to rotate; and the assigned torque is exerted to the small solid rocket through the tightening tool so that the spray pipe and a shell can be tightened. By means of the assembling method, the number of tools is decreased, the labor intensity is lowered, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to a small rocket automatic assembly device and an assembly method, belonging to the field of pyrotechnic device assembly. Background technique [0002] The small solid rocket is a typical aerospace pyrotechnic device, which plays an important role in the separation of forward (reverse) propulsion, fairing separation, star rocket spin-up, barrel cover side thrust, warhead attitude adjustment and control, etc. [0003] See attached figure 1 , the shell 31 of the solid small rocket is a typical cylindrical thin-walled structural part, which is prone to deformation during the assembly process; Torque (generally hundreds of N·m) to ensure a reliable threaded connection between the shell and the nozzle. At present, domestic small solid rockets are assembled by hand. This assembly method first needs to design special tooling according to the shape characteristics of the rocket, that is, the outer diameter of the shell 31 and the shape...
