Painting process door lock

Abstract

The invention discloses a painting process door lock, which is installed in a lock hole on a car door and includes a step positioning pin, a supporting clamp and a spring body, the step positioning pin and the supporting clamp are fixed on the positioning area of ​​the spring body, and the positioning One end of the positioning area is clamped with the edge of one side of the lock hole through the step positioning pin, the other end of the positioning area is in contact with the edge of the other side of the lock hole under the action of the elastic force of the positioning area itself, and the supporting clamp is clamped on the other side of the lock hole. On the supporting edge next to the side edge, the positioning area of ​​the spring body elastically extends out of the deformed clamping area, and the deformed clamping area includes a door frame clamping groove that is clamped and matched with the edge of the door frame. The coating process door lock of the present invention utilizes the elastic characteristics of the spring body, the step positioning pin and the support clamp to self-limit, and has the characteristics of simple structure, convenient manual operation, not easy to be damaged, and does not require excessive maintenance; the positioning area is installed on the door Inside the lock hole, there is almost no spray covering, and a door lock completes all the processes of primer, top coat, and glue coating.

Description

technical field [0001] The invention relates to the technical field of vehicle painting, in particular to a painting process door lock. Background technique [0002] At present, due to the popularization of automated production lines, when the car body enters the painting process, the spraying operations on the inner and outer surfaces of the car body are all performed by machines. In the body painting line, in order to ensure the smoothness of the body, it is necessary to complete processes such as electrophoresis, gluing, and painting. This requires the installation of process door locks before painting to maintain a certain door opening angle and frequent door opening and closing actions. [0003] Some of the commonly used coating process door locks in the prior art are strut type, some are binding type, etc., all need to select suitable screw joints or binding points on the door frame. No matter the screw joint or the binding point is stressed, the parts will be deforme...

AI Technical Summary

Problems solved by technology

No matter the screw joint or the binding point is stressed, the parts will be deformed, and the opening and closing of the car door requires workers to loosen and tighten the nuts, which has high requirements for human work, and it takes time and effort to affect the spraying cycle of the coating line.

The fixing part of the screw is covered, and it needs to be repainted, which will affect the appearance of the paintwork of the cab
