Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Such as Figure 2-7 As shown, the cable seat assembly positioning tool includes the first set of cable seat positioning plates 3 and the subsequent cable seat positioning plates 4 . The first group of cable seat positioning plates 3 are used for the assembly and positioning of the first group of cable seats 2 of the combustion chamber shell, which are assembled based on the front end face (end face A) of the combustion chamber shell. The follow-up cable holder positioning plate 4 is a group of cable holders 2 assembled on the basis of the previous group of positioned cable holders 2 . If the distance between two adjacent groups of cable holders 2 is different, it can be designed and processed according to the structure of the follow-up cable holder positioning plate 4 as required, and only the length can be changed.

The invention relates to an assembling positioning tool and method for solid rocket engine cable seats. The assembling positioning tool is composed of a first cable seat positioning plate and a next cable seat positioning plate. The first cable seat positioning plate is used for assembling positioning of a first set of cable seats of a combustion chamber shell of a solid rocket engine. The first cable seat positioning plate is used for assembling with the front end face of the combustion chamber shell of the solid rocket engine as the reference end face A. The next cable seat positioning plate is used for assembling the next set of cable seats with the previous set of positioned cable seats as the reference. According to the assembling positioning tool and method for the solid rocket engine cable seats, the positions of the cable seats are determined quickly and precisely through the tool, a manual scribing assembling method is replaced with the tool, positioning and welding are conducted after quick assembling is conducted, the cable seats are clamped by the tool, the offset, caused by weld seam shrinkage, of the positions of the cable seats is reduced, and the production efficiency and the assembling precision are improved.
Description
technical field [0001] The invention relates to an assembly and positioning tool for a cable seat, in particular to an assembly and positioning tool for a solid rocket motor cable seat. Background technique [0002] Such as figure 1 As shown, some solid rocket motor combustor shells 1 are provided with sets of cable holders 2 for fixing cables, and the spacing and position accuracy of each set of cable holders are required to be high. The connection method between the cable seat and the combustion chamber shell is usually welded. [0003] The existing assembly and positioning method of the cable seat is to manually mark the position line, and then assemble the line one by one. The production and assembly process is cumbersome, the marking time is long, the assembly speed and precision are low, the production efficiency is low, and the weld seam is prone to occur after positioning welding. Shrinkage and deformation may cause the position of the cable holder to shift. Cont...
