压力容器封头框架的搅拌设配摩擦力焊接加工设配以至于最简单的方法

本问世开放化一个多种火箭队主要燃料贮箱锅筒的绞拌静摩擦焊装备，具有：稳定在座子上的外立柱与内立柱；她们的上方面利用汽动夹紧组织 无线链接或松掉；内立柱上布置有焊组合夹具和齿轮变速箱组织 ；齿轮变速箱组织 上布置有焊夹头的；焊夹头的上布置有绞拌头，焊夹头的利用齿轮变速箱组织 可环绕着内立柱上、下中长跑；焊夹头的利用导轨与夹头的底托无线链接，可沿夹头的定位中长跑；焊夹头的与夹头的底托可是起环绕着导轨在向下定位中长跑；外立柱稳定有焊垫块；在座子周，还利用铺助立柱布置有若干份个铺助平衡装置。本问世还开放化了类似这些焊装备的焊手段。本问世重要升高了锅筒空间结构的接线头机械性能和生产方式热效率，降了焊弊病的形成率。

Friction-stirwelding equipment for cylindrical structure and welding method thereof

Theinvention discloses friction-stir welding equipment for a rocket fuel storagetank cylinder and further discloses a welding method of the welding equipment. Thefriction-stir welding equipment comprises an outer vertical column and an innervertical column which are fixed to a base. The upper end faces of the outer verticalcolumn and the inner vertical column are connected or loosened through apneumatic locking mechanism; a welding clamp and a transmission mechanism are mountedon the inner vertical column; a welding spindle is mounted on the transmission mechanism,and a stirring head is mounted on the welding spindle; the welding spindle canmove up and down along the inner vertical column through the transmissionmechanism, is connected with a spindle base through a guide rail and can movein the spindle direction, and the welding spindle and the spindle base can movein the vertical direction along the guide rail; a welding base plate is fixedto the outer vertical column; and a plurality of auxiliary devices are further mountedaround the base through auxiliary vertical columns. The joint performance andproduction efficiency of a cylindrical structure are improved significantly,and the occurring rate of welding defects is decreased.
