Special door jig for coating

Abstract

The invention relates to a special door jig for coating. The door jig comprises a positioning and supporting device, a door buckling device and a rotatable connecting rod, wherein the positioning and supporting device comprises a vertical positioning surface, the vertical positioning surface is provided with more than three downward opening hooks which are not in a same straight line, and all thedownward opening hooks can be hung into the technological holes on the inner wall of a vehicle; the positioning and supporting device also comprises a positioning and locking bolt which transversely traverses the positioning surface, and the positioning and locking bolt can be transversely inserted into the technological holes on the inner wall of the vehicle when the special jig is arranged; thedoor buckling device comprises a positioning column and a positioning padlock, the positioning column can be inserted into one technological hole on the inner side of the vehicle door, and the positioning padlock can tightly lock the other technological hole on the inner side of the vehicle door; the rotatable connecting rod comprises a first segment and a second segment; and the positioning and supporting device is provided with a limiting device which can limit the rotation angle of the second segment of the rotatable connecting rod. The special door jig for coating is convenient to mount and position and can effectively avoid the falling of paint slag to a door pedal during coating.

Description

technical field [0001] The invention relates to an automobile painting equipment, in particular to a special door fixture for painting. Background technique [0002] In the painting process, since the door of the car body is easy to swing, open, or be damaged due to interference with other objects during the flow of the car body on the line, it is necessary to install the door fixture in the pre-processing; Fits snugly on the door frame. The isolator in the prior art is usually installed on the door frame wall; and the door clamp is usually installed on the door frame wall through a bolt structure at one end, and the other end is installed on the door, and the end installed with the door frame wall is the rotating end of the clamp. However, in the operation, a large amount of paint slag often falls on the door pedal. The main reasons for this phenomenon are: [0003] 1. When the fixing screw of the door fixture is too loose, the screw will rub against the lever of the fixt...

AI Technical Summary

Problems solved by technology

[0003] 1. When the fixing screws of the door fixture are tightened too loosely, the screws will rub against the lever of the fixture during the operation process, causing the paint particles to fall off; when the inner panel of the door is sunken and hollowed out toward the outside, the opening and closing of the door will easily cause the particles to fall off the pedal

[0004] 2. The position of the fixing bolt and the rotating shaft of the door clamp is above the four-door pedal. This position is the movable point of the clamp. When opening and closing the door, especially when the door shakes, friction is likely to occur, resulting in a large amount of paint residue particles falling on the pedal;

[0005] 3. When the door fixture is reused, the paint particles will fall due to the unclean cleaning of the screw at the connection end

[0006] These pedal particles account for 95% of the particles in the car body, which seriously affects the coating quality, and causes a lot of rework, affecting the production schedule. Therefore, it is necessary to provide an improved fixture to solve this problem
