Embodiment 1

[0075] This embodiment provides a method for manufacturing a leak hole in a car door, the method comprising:

[0076] Step 101: Divide the volume of liquid in the cavity of the inner panel of the vehicle door and the outer panel of the vehicle door into multiple sub-volumes, and the liquid in each sub-volume includes an upper liquid surface and a lower liquid surface.

[0077] Step 102, obtain the distance from the center of the mounting hole of the guard plate of the car door, the center of the mounting hole of the door frame bar of the car door, the center of the mounting hole of the buffer block of the car door, and the center of the leaking hole of the car door to the upper liquid level of each sub-volume of liquid vertical distance.

[0078] Step 103 , obtaining the area of ​​the installation hole of the guard plate of the vehicle door, the installation hole of the door frame strip of the vehicle door and the installation hole of the buffer block of the vehicle door.

Abstract

The invention discloses an automobile door liquid leakage hole manufacture method and belongs to the field of automobile part manufacture. The method includes dividing volume of the liquid in the cavity of inner and outer plates of an automobile door into a plurality of sub volumes comprising upper levels and lower levels; acquiring the perpendicular distances of the center of a protecting plate mounting hole, frame stripe mounting hole, buffering block mounting hole and liquid leakage hole of the automobile door to the upper level of each sub volume of the liquid; acquiring the area of the mounting holes; presetting the area of the liquid leakage hole; determining the total liquid leaking time of the sub volumes of the liquid according to the sub volumes and the acquired parameters; if the total liquid leaking time is larger than the standard liquid leaking time and the difference is smaller than 3s, determining the size of the liquid leakage hole according to the preset area of the liquid leakage hole, and manufacturing the liquid leakage hole in the automobile door directly according to the size. Repeated modifications of the liquid leakage hole is avoided, and manufacture cost is reduced.

Description

technical field [0001] The invention relates to the field of auto parts design, in particular to a method for manufacturing a liquid leakage hole of a car door. Background technique [0002] In order to facilitate the installation of auto parts and the discharge of liquid in the cavity of the door inner panel and outer panel, guard plate mounting holes, door frame bar mounting holes, buffer block mounting holes and liquid leakage holes are usually set on the car door inner panel of the automobile. The number, size and location of the above mounting holes and leak holes vary depending on the vehicle model. Among them, during the electrophoretic coating process of the car door, the size of the leakage hole must be large enough to allow the pre-electrophoresis treatment liquid to drain from the leakage hole within the standard leakage time (that is, the leakage time corresponding to the planning of the painting workshop). , to prevent the undrained electrophoretic pretreatment...
