Abstract

The invention relates to a split-assembling fixture of a car backdoor comprising a glass positioning device connected on a rectangular bottom plate and a hinge positioning device, and is characterized in that the glass positioning device comprises an auxiliary supporting block connected with rear middle part of the rectangular bottom plate, two first glass limiting piles symmetrically arranged behind the rectangular bottom plate, two glass limiting piles symmetrically connected with the left and the right sides of the rectangular bottom plate, and two auxiliary limiting blocks symmetrically connected with the front side of the rectangular bottom plate; the hinge positioning device comprises two hinge positioning pin supporting seats and two hinge positioning pins symmetrically connected with the rear part of the rectangular bottom plate and positioned outside two first glass limiting piles. The positioning precision is high; the peripheral gap between backdoor glass and car body is finely adjusted or even not adjusted during assembling process; and the invention can not only satisfy the assembling quality requirement but also improve the assembling efficiency.

Description

technical field [0001] The invention belongs to the technical field of car manufacturing, and in particular relates to a car back door subassembly fixture. Background technique [0002] At present, the back door of a car is generally composed of a back door frame and glass. The rear door frame and car body composed of sheet metal parts and welded parts have been assembled, and the final assembly only needs to assemble glass and other parts. The glass is bonded directly to the back door frame. [0003] There are also some cars whose back doors do not need the welding assembly of the back door frame, but are only composed of glass and parts. During assembly, the back door glass is connected to the car body through the back door hinge. And assemble other parts. [0004] For the back door of the car, there is no back door frame welding assembly, which is only composed of glass and parts. The assembly process is more complicated, and it is difficult to adjust the back door cl...
