Description

Door opening and closing preventing device

Technical Field

The embodiment of the application relates to the technical field of temporary fixing devices for vehicle doors, in particular to an opening and closing preventing device for vehicle doors.

Background

A finish paint tool is required to be equipped in a full-automatic spraying process of an inner plate and an outer plate of a vehicle body in the whole vehicle coating process, so that the vehicle door can be normally opened during spraying, the vehicle door can be kept in a closed state after the spraying is finished, the vehicle door and a side wall are isolated, and paint films are prevented from being damaged by collision.

The device for preventing the door from opening and closing in the whole automobile coating process comprises a finish paint anti-closing tool, a lock catch elastic tool and a magnetic anti-opening and anti-closing two-in-one tool.

The finish paint anti-closing tool is usually matched with a special vehicle door limiter for coating. The anti-closing tool is used for supporting the vehicle door, preventing paint films from damaging the vehicle door and the side walls, and the limiter is used for preventing the vehicle door from being automatically opened and limiting the opening. However, in practical application, the relative positions of the vehicle door and the side wall are greatly influenced by the overall modeling of the vehicle, so that the same limiter is difficult to ensure that the vehicle doors of different vehicle types reach the required opening simultaneously, thereby influencing the accessibility and the spraying quality of the internal spraying robot; and when installing the stopper, need manual tightening be located the fixed screw between door inside and outside board, the connecting screw of the fixed stopper of rethread trigger and side wall is because of being limited to the operation space of door inside and outside board, door inner panel and side wall slit department, and door stopper loading and unloading operation is difficult, and takes time long.

The lock catch elastic tool is provided with the pin positioning tool at the side wall lock catch mounting hole, the lock hole of the vehicle door is provided with the elastic matching hole tool, the lock catch elastic tool is matched with the pin positioning tool, and the vehicle door is closed and opened with a certain force, so that the four doors are normally opened and closed during internal spraying, and the vehicle door can be kept closed and paint film bruise can not occur in other manufacturing links. However, when the lock catch elastic tool is repeatedly used, the problem of poor matching of the pin positioning and elastic matching hole tool is easy to occur due to the reasons of paint accumulation, deformation, elastic attenuation and the like, so that the function is invalid.

The magnetism prevents opening and prevents two unification frock of switch installs in side wall threshold department through couple and draw-in groove, adsorbs the door inner panel with the help of convex button form magnet to compromise and prevent that the door from opening and prevent the door and side wall contact closed function. However, as the baking procedures are more in the coating process, when the magnetic anti-opening and anti-closing two-in-one tool is reused, the magnetic round blocks are easy to demagnetize due to multiple times of high-temperature baking, so that the problem of attenuation or loss of the functions of the tool is caused; in addition, the coating process flow is complex, the vehicle body walks on the conveying line in the manufacturing process, the vehicle body inevitably suffers from working conditions such as vibration, acceleration, scram and the like, the magnetic adsorption is simple, the superposition of the flatness of the adsorption surface is influenced, and the risk that the vehicle body collides with coating equipment due to the fact that the vehicle door is opened in the middle exists.

In summary, in the prior art, the device for preventing the door opening and closing in the whole automobile coating process of the automobile is higher in mounting difficulty or poor in stability, influences the whole automobile coating process of the automobile, and causes the risk of paint film bruise in the whole automobile coating process of the automobile.
