Special door jig for coating

Abstract

The invention relates to a special door jig for coating. The special door jig is characterized in that: the special door jig comprises a positioning device, an isolation device and a door buckling device; the positioning device comprises a positioning and supporting frame, a positioning column, a door position clipping device, a positioning tension rod, and a tension spring; the isolation device is an isolation rod which is fixed on the positioning surface of the positioning and supporting frame, the isolation rod extends from the positioning surface of the positioning and supporting frame, and the vertical distance from the tail end of the isolation rod to the positioning surface is greater than the thickness of a vehicle doorframe, so the vehicle door cannot contact the doorframe when the vehicle door is closed during coating; and the door buckling device comprises a bent rod supporting apparatus which is fixed on the positioning and supporting frame and a bent positioning rod whichrotates in the bent rod supporting apparatus, the end part of the bent positioning rod is at a certain radical distance from the rotation shaft of the bent positioning rod, and the end part of the bent positioning rod can insert into a technological hole in the vehicle doorframe when the vehicle door is opened. The special door jig for coating can be applied to the coating technology and can effectively prevent the generation of spray particles on a vehicle door pedal.

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 pull rod of the f...

AI Technical Summary

Problems solved by technology

[0003] 1. When the fixing screw of the door fixture is too loose, the screw will rub against the lever of the fixture during the operation process, causing the paint particles to fall off;

[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 cleaning of the screw at the end connected to the door frame wall.

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