The invention discloses a door frame structure and a machining process thereof. The door frame structure comprises a rearview mirror mounting plate assembly and a B-pillar guide rail assembly. The upper parts of the rearview mirror mounting plate assembly and the B-pillar guide rail assembly are fixedly connected with a front door glass upper guide rail, and the lower parts of the rearview mirrormounting plate assembly and the B-pillar guide rail assembly are fixedly connected with a front door inner window frame reinforcing plate; the door frame structure is made of aluminum profiles. According to the door frame structure, the aluminum profile serves as the main material, compared with a steel door frame, the overall mass is reduced, and the lightweight design is achieved; besides, in order to achieve burn-in welding of a B-pillar cover plate and a vehicle door glass rear guide rail, connectors are reserved for the B-pillar cover plate and the vehicle door glass rear guide rail respectively, and burn-in welding fixing is completed after lap joint; and finally, after the rearview mirror mounting plate assembly and the B-pillar guide rail assembly are formed respectively, the automobile door glass upper guide rail and the front door inner window frame reinforcing plate are welded and fixed, and machining of the door frame structure is completed.

    本发明公开了一种门框结构及其加工工艺,包括后视镜安装板总成以及B柱导轨总成;所述后视镜安装板总成和B柱导轨总成上部固连有前门玻璃上导轨,所述后视镜安装板总成和B柱导轨总成的下部固连有前门内窗框加强板;该门框结构材质选用铝型材。本发明的门框结构以铝型材作为主要材质,相比钢制门框降低了整体质量,实现轻量化设计;另外,为了实现B柱盖板和车门玻璃后导轨的烧焊焊接,两者分别预留出连接体,搭接后完成烧焊焊接固定;最终分别成型后视镜安装板总成和B柱导轨总成后将车门玻璃上导轨和前门内窗框加强板焊接固定,完成门框结构的加工。
