The invention discloses a train brake cylinder non-pressure head and a welding auxiliary device thereof. The non-pressure head comprises a horn-shaped body, the caliber of a rear end opening of the body is larger than that of a front end opening of the body, an annular edge arranged towards the outer side of the rear end opening of the body is arranged on the rear end opening of the body, the annular edge is perpendicular to the central axis of the body, an assembling hole and a plurality of air chambers evenly distributed along the circumference are formed in the annular edge, and a vent holeis formed in each air chamber; a lining part coaxial with the body is welded in the body, the lining part is composed of an annular lining plate and a center pipe, and the center pipe stretches out towards the rear side of the body. The head is compact in structure, good in mechanical performance and convenient to weld and assemble, the balance and high efficiency of air inlet and outlet of the train brake cylinder on the pressure-free head side are guaranteed, the pressure-free head is more stable in structure, and noise pollution is greatly reduced.
本发明公开了一种火车制动缸无压头及其焊接辅助装置,具有喇叭状本体,本体后端口的口径大于其前端口的口径,在本体的后端口设有朝其外侧布置的环形沿边,环形沿边垂直于本体的中轴线布置,并在环形沿边上设有装配孔和若干个沿圆周均布的气室,每个气室上均配置有通气孔;在本体内焊装有与其同轴布置的内衬件,内衬件由圆环形的内衬板和中心管组成,中心管朝向本体的后侧伸出;本发明结构紧凑、机械性能好、焊接组装方便,确保了火车制动缸在无压头侧进、出气的均衡性和高效性,使得无压头在结构上更加稳固,并大大减小了噪音污染。
