Car door limiting device for car coating

Abstract

The invention discloses a car door limiting device for car coating. The car door limiting device for car coating comprises a limiting rod. Spring washers are welded to the left and right ends of the limiting rod correspondingly. A left spring is welded to the left end face of the left spring washer. The left end face of the left spring is fixedly connected with a push rod through the corresponding spring washer. The spring washer on the right side is fixedly connected with a right spring. The right end face of the right spring is connected with a supporting rod through the corresponding spring washer. A right rod body of the supporting rod is provided with a cylindrical hole. A cylindrical rod is inserted in the cylindrical hole and is fixedly connected with a U-shaped lug. The lower side of the U-shaped lug is fixedly connected with a fixation clamp. The car door limiting device is clamped onto a car frame through the fixation clamp; the limiting rod is used for limiting, and a magnet is attracted onto a car door to achieve the purposes of stably supporting the car door and limiting the car door. The car door limiting device is convenient to dismantle and capable of reducing the working hours and improving the car coating efficiency. By means of the design of the springs and rubber, the car door limiting device can absorb shock and protect a car door. Friction force is larger. The limiting effect is more stable.

Description

Technical field [0001] The invention relates to the technical field of automobile limit auxiliary tools, in particular to a door limit device for automobile painting. Background technique [0002] In order to ensure uniform spraying of intermediate and top coats, automobile manufacturers need to open the door to a certain angle and keep the door still before painting to avoid collision between the door and the body and damage the paint surface. The traditional operation method is to install a limit bolt on the body body, or install a limiter between the door and the body body. [0003] The method of installing the limit bolts does not completely limit the door. The bolts are easy to hit the door inner panel during the operation or turnover of the body, causing the door inner panel to deform, and also destroy the electrophoresis and middle coating of the deformed part; install the limit The method of installation and disassembly is inconvenient, and the operation efficiency is low;...

Problems solved by technology

[0003] The method of installing the limit bolt does not completely limit the door. During the operation or turnover of the car body, the bolt is easy to bump the inner panel of the door, causing deformation of the inner panel of the door, and also destroys the electrophoresis and middle coating of the deformed part; installation limit It is inconvenient to install and disassemble the method of the stopper, and the work efficiency is low; and the existing door stopper is to fix the stopper in the mounting hole on the car door or the car, because the car will rotate and move during the painting process, it will Pressing the limiter, and then compressing the support point of the limiter, will damage the mounting hole of the car, causing troubles in secondary processing and wasting man-hours
