Cementing assembly die used for bearing cylinder

Abstract

The invention discloses a cementing assembly die used for a bearing cylinder. The cementing assembly die includes a base provided with a spigot positioning ring, and the spigot positioning ring is used for fixing a lower end frame of an annular structure. Four sets of stand columns distributed in a square mode are arranged on the outer side of the spigot positioning ring. Each set of stand columns are provided with a plurality of layers. The stand columns are provided with layer connecting plates. Each layer connecting plate is in a netty shape. Layer positioning plates are arranged at the tail ends of the layer connecting plates. The cementing assembly die has the advantages that as the frame type structures which are independent and relevant are adopted, so the rigidity and the assembly accuracy of the whole die are improved, the planeness and parallelism tolerances of an upper end frame, the lower end frame and layer plates of the bearing cylinder can meet technological requirements, and hole position tolerances are smaller than or equal to 0.4 mm at present; the lower end frame is positioned through the spigot positioning ring, and the axiality tolerance of the upper end fame and the lower end frame of the bearing cylinder is smaller than or equal to 0.50 mm at present; as the layer connecting plates are each of a latticed integrated welded structure, the weight of the layer connecting plates is reduced by 60% or so.

Description

technical field [0001] The invention relates to a mold, in particular to an adhesive joint assembly mold for a bearing cylinder. Background technique [0002] The load-bearing cylinder is the load-bearing structure that carries the main load of the satellite, and is the core of the assembly of the entire satellite structure. Most structural components are combined around the load-bearing cylinder. Therefore, the upper and lower end frames, the middle end frame and the storage tank of the load-bearing cylinder The assembly accuracy of the flange and other laminates and the cylinder will directly affect the performance of the bearing cylinder product. The assembly of the upper and lower end frames, the middle end frame, the tank flange and the cylinder body of the load-bearing cylinder adopts the load-bearing cylinder glued assembly mold. Before the present invention, the structural forms of the load-bearing cylinder glued assembly mold are: The assembly method of the lower e...
