Description

Technical Field

[0001] The present application relates to the technical field of automobile spraying, and in particular to a painting and spraying tool for a side-opening automobile tailgate. Background Art

[0002] At present, most of the doors on the inner frame of the automobile body and the inner side of the opening parts are automatically sprayed by robots. Among them, the side-opening tailgate is easy to open by itself during the automatic spraying process of the robot, and there is a risk of collision with the internal spraying robot. It is necessary to add an anti-opening device to the tailgate. There are two forms of conventional tailgate anti-opening devices. One is to use a hard connection method, such as a spring hook, to lock the tailgate opening. Once the lock is installed, the robot cannot open it automatically, and it is necessary to manually unlock the anti-opening device before the robot sprays the inner frame. The other is to use a limit fixture to constrain the door opening on the hinge side of the tailgate. The limit fixture needs to be installed with the help of the tailgate limiter mounting hole, which has great limitations and is not suitable for situations without a tailgate limiter, such as pneumatic strut tailgates.

[0003] In the related art, a four-door painting and spraying tool adopts a clamping part to clamp the door frame sheet metal of the vehicle body, which can limit the inward opening change of the door, and at the same time adopts an annular magnet to achieve the positioning requirement of the door opening, avoiding the complicated operation of manual unlocking to open the door. However, the opening of the door depends entirely on the height of the magnet, so the height of the magnet needs to be made larger, resulting in a larger overall volume of the magnet and a smaller contact surface with the door. The magnet is prone to breakage during use, and the stability and applicability of the device are greatly affected.

[0004] Therefore, it is necessary to design a side-opening automobile tailgate coating and spraying tooling to solve the above problems. Utility Model Content
