The invention discloses an end door stand column for a railway vehicle and a machining method of the end door stand column. A reinforcing mechanism used for increasing the structural strength of a vertical square pipe is fixed into the vertical square pipe, a plurality of open grooves are formed in the inner side edge of the vertical square pipe, a supporting base is used for being movably connected with a hinge rotating shaft on the side edge of a door body, and bolt locking is conducted, so that the rear end of a locking base is clamped and fixed to a positioning base; and meanwhile, the clamping jaw mechanism at the front end of the supporting seat is clamped and fixed with the inner side wall of the vertical square tube, so that the vertical square tube, the reinforcing mechanism and the supporting seat are firmly connected into a whole. Through locking of the bolts, the locking base and the positioning base on the reinforcing mechanism can be automatically buckled and fixed, meanwhile, the front end of the supporting base and the vertical square pipe are buckled and fixed, finally, the vertical square pipe, the reinforcing mechanism and the supporting base are firmly connected into a whole, in this way, operation is easy and fast, the supporting performance of the supporting base after installation and fixing is enhanced, and the service life of the supporting base is prolonged. After the hinged rotating shaft on the side edge of the door body is inserted into the shaft sleeve on the supporting seat, the door body can be stably supported.
本发明公开了一种轨道车辆用端门立柱及其加工方法,竖直方管的内部固定有用于增加其结构强度的加强机构,竖直方管内侧边设有若干组开槽,支撑座用于活动连接门体侧边的铰接转轴,螺栓锁紧,使得锁紧座后端与定位座卡紧固定,同时支撑座前端的卡爪机构与竖直方管内侧壁卡紧固定,实现竖直方管、加强机构和支撑座牢固连接为一体。本发明通过螺栓的锁紧,可实现锁紧座与加强机构上的定位座进行自动卡扣固定,同时使得支撑座前端与竖直方管卡扣固定,最终实现竖直方管、加强机构和支撑座牢固连接为一体,这样操作简单,快捷,增强了支撑座安装固定后的支撑性,在门体侧边的铰接转轴插入至支撑座上的轴套筒后,可以对门体形成稳定的支撑。
