A universal four-door limit tooling for car body

Abstract

The invention discloses a universal four-door limiting tool for a vehicle body. The limiting tool comprises a fixing mechanism and further comprises a clamping mechanism, a limiting mechanism and an adjusting mechanism. The clamping mechanism is used for clamping the upper frame of an inner plate of each vehicle door, the limiting mechanism is used for limiting the position of each vehicle door, and the adjusting mechanism is used for adjusting the clamping mechanism to achieve loosening and clamping by being matched with the fixing mechanism and used for adjusting the position of the limiting mechanism to control the opening-closing angle of each vehicle door. The opening angles of the four doors universal for the vehicle body are accurately adjusted and controlled, so that the finishing coat spraying quality is improved, and repeated adjustment and the like caused by inconsistent opening and closing angles of the four doors of an automatic machine is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile production, and in particular relates to a universal four-door position-limiting tool for a vehicle body. Background technique [0002] The outer surface of the whole vehicle is automatically sprayed by robots. When the automatic machine sprays the outer surface of the car body, the opening and closing angle of the door directly affects the quality of the painting. The larger the angle is, the easier it is to form an angle between the automatic machine and the outer surface of the door, and the paint hangs upside down when spraying paint . If the four doors of the vehicle body fail to open automatically, it will inevitably cause serious equipment collision accidents. Secondly, in order to meet the spraying quality of the inner cavity of the car body and the corrosion resistance of the substrate, each coating must be manually sprayed in the inner cavity of the car body. During the spraying proc...

Problems solved by technology

In recent years, the competition in the automobile market has been fierce. Every automobile company has accelerated the development of new models. The traditional four-door limit tooling is not very versatile, and the opening and closing angle of the door cannot be precisely controlled and adjusted, so it cannot meet the requirements of the door. It is not conducive to the programming of the robot's display calibration program to ensure the consistent state of the whole car in the spraying and color paint, and it is impossible to guarantee the consistency of the paint film thickness and color of each part of the car body. Therefore, it is urgent to design a set of precise control of the four-door opening. Angle-fitting and universal body four-door limit tooling
