Aluminum alloy rectangular pipe network shell node based on linear friction welding and connecting method thereof
The invention discloses an aluminum alloy rectangular pipe network shell node based on linear friction welding and a connecting method thereof. A rectangular pipe and a sealing plate of aluminum alloyrectangular pipe network shell nodes are made of aluminum alloy, a sleeve is connected with a prism section of a high-strength bolt through a pin, a nut is covered with a protective cover fixed to the sealing plate, one end of the rectangular pipe is arranged outside the protective cover in a sleeving mode, the thickness of the nut is smaller than the depth of the protective cover, and the end face of the rectangular pipe is connected with the sealing plate through linear friction welding. According to the aluminum alloy rectangular pipe network shell node based on linear friction welding andthe connecting method thereof, the connecting method is used for connecting the network shell nodes. The protective cover, the sealing plate and the rectangular pipe are introduced, then inner flashes generated during friction welding cannot affect the high-strength bolt, the protective cover has a limiting effect on the nut, when the high-strength bolt is screwed into a bolt table, limiting of the pin on the high-strength bolt is not needed, the high-strength bolt cannot slide into the rectangular pipe, thus no sliding groove needs to be formed in the high-strength bolt, and the overall structural strength is high.
本发明公开了一种基于线性摩擦焊接的铝合金矩形管网壳节点及其连接方法，本发明网壳节点的矩形管和封板采用铝合金，套筒与高强螺栓的棱柱段通过销钉连接，螺帽外罩有固定在封板上的防护罩，矩形管的一端套在防护罩外，螺帽的厚度小于防护罩的深度，矩形管的端面与封板采用线性摩擦焊接连接。本发明连接方法用于连接前述网壳节点。本发明通过引入防护罩，封板和矩形管在实施摩擦焊接时产生的内飞边不会影响高强螺栓，而防护罩对螺帽有限位作用，在向螺栓台旋入高强螺栓时，不需要销钉对高强螺栓的限位，高强螺栓也不会滑入到矩形管中，因此高强螺栓上不需要开设滑槽，整体结构强度高。
