Four-door universal tool for processing electrophoresis before coating

The invention discloses a four-door universal tool for processing electrophoresis before coating. The tool comprises a connecting rod, positioning structures and a hooking and tensioning mechanism, wherein the positioning structures are arranged at the two ends of the connecting rod, and the hooking and tensioning mechanism can be deformed to form a tensioning force; and one end of the connectingrod is connected to a vehicle body in a hooked mode through the hooking and tensioning mechanism, and the other end is connected to a vehicle door in a positioning mode through a positioning structure. According to the tool, the vehicle door can be firmly connected to the vehicle body, so that the opening angle of the vehicle door and the vehicle body is guaranteed. 本发明公开了种涂装前处理电泳的四门通用工装，所述工装包括连接杆、分别设于连接杆两端的定位结构和可形变形成拉紧力的钩合拉紧机构，所述连接杆的端通过钩合拉紧机构与车身钩合连接，另端通过定位结构与车门定位连接。该工装能够使得车门与车身的紧固连接，从而保证车门与车身的开启角度。
