Description

转向架构架側横梁连接接头全对接结构及组焊工艺方法 技术领域
本发明涉及一种构架侧横梁连接接头全对接结构及组焊工艺。
背景技术
构架侧横梁连接接头结构因设计思想局限和组焊工艺限制， 无法实现全对 接结构连接， 侧横梁接口多数设计成角接结构或角接与对接联合结构； 个别的 也有搭接结构。 由此， 侧横梁接头处特别是焊缝区域应力集中系数较大， 降低 了构架的疲劳寿命， 影响着转向架的承载能力和运行速度。
发明内容
本发明所要解决的技术问题是提供一种焊缝区域应力集中最小的转向架构 架侧横梁连接接头全对接结构及组焊工艺， 以此来提高构架的疲劳寿命， 使转 向架运行更加安全可靠。
为解决上述技术问题， 本发明提供一种转向架构架侧横梁连接接头全对接 结构， 其特征在于： 侧梁与横梁通过连接座实现全对接连接， 其侧梁连接端与 侧梁内立板形成板一板对接接头结构， 其横梁连接端与横梁形成管一管对接接 头结构。
转向架构架侧横梁连接接头全对接结构组焊工艺方法， 其特征在于： 连接 座与横梁管组焊 横梁组成组焊 连接座与侧梁槽内立板及导柱組焊 侧梁加强隔板及上盖板组焊 构架整体组焊。
连接座与横梁管悴接釆用机械手 MAG焊方法， 其余釆用手工 MAG焊方法。 连接座与横梁管采用双面焊时进行清根， 侧梁内立板对接焊时采用村垫。 本发明新的侧梁与横梁连接接头使构架侧梁与横梁实现了全对接连接， 同 时， 利用连接座使连接焊缝避开了应力较高的截面和形状变化大的区域， 从焊 接结构理论上讲这是最理想的接头结构， 即： 焊接接头处应力集中最小、 焊接 填充量最小、 焊接残余应力及变形最小； 结构外形连续、 美观； 承载能力和抗 疲劳能力强。 本发明突破了侧梁和横梁均为成品后再合成构架的传统工艺， 其 优势远超于现有结构的角连接结构或角连接与对接联合结构， 更大大优越于搭 接结构。
附图说明
附图是侧横梁连接接头全对接结构示意图。
具体实施方式
参照图 1 ,侧梁与横梁 1通过连接座 2实现全对接连接， 其侧梁连接端与侧 梁内立板 5及导柱 3形成板一板对接接头结构， 其横梁连接端与横梁形成管一 管对接接头结构， 4是上盖板， 6是下盖板， 7是侧梁加强隔板。
侧横梁全对接结构的转向架构架组焊工艺： 当侧梁为半成品 （无上盖板的 侧梁槽） 时与横梁组成完成构架整体组对， 是新的构架组焊工艺最突出的特点 之一， 此工艺突破了侧梁和横梁均为成品后再合成构架的传统工艺， 利用这种 工艺能够保证横梁管与连接座实现自动 MAG 焊接； 能够实现侧梁加强隔板的顺 利组焊； 能够确保横梁组成与侧梁内立板的精确组对和优质焊接。 连接座与横 梁管焊接采用成熟的机械手 MAG焊方法， 焊缝进行 RT检验； 连接座与侧梁槽内 立板及导柱焊接釆用可移除衬垫手工 MAG焊方法， 焊缝进行 UT检验， 具备可靠 的焊缝质量保证。 连接座与横梁管焊前采用无间隙组对， 在焊接规范一致的情 况下使得焊接收缩量准确统一， 可使横梁组成长度控制在 ± 0. 5范围内， 无需二 次加工， 即可保证横梁组成与侧梁槽完成精确的组对和焊接。
