Background
The automobile sealing strip is an important component part in automobile parts and is mainly responsible for the sealing effect of a gap between an automobile opening and closing part and a white automobile body so as to prevent polluted gas, dust, rainwater and the like outside the automobile from entering the automobile through the gap between the opening and closing part and the white automobile body. The door sealing strip is one of a plurality of automobile sealing systems, is assembled on a side wall spigot of an automobile and is used for sealing a gap between a door and a side wall and preventing polluted gas, dust, rainwater and the like outside the automobile from entering the automobile through the gap between the door and a white automobile body; in the development and design process of the automobile, the gap distance between the automobile door and the side wall is required to be within a certain tolerance range, when the gap distance between the automobile door and the side wall is lower than a designed minimum value, the reaction force value during closing the door can be obviously increased, the door closing quality is reduced, and even the automobile door cannot be closed when serious; when the gap distance between the vehicle door and the side wall is higher than the designed maximum value, the sealing performance between the vehicle door and the side wall is reduced, so that polluted gas, dust and rainwater enter the vehicle through the gap between the vehicle door and the side wall of the white vehicle body, and subjective feeling of passengers in the vehicle is affected; therefore, it is particularly important to detect the sealing gap between the vehicle door and the side wall in the vehicle design and production process.
The traditional measuring method is mainly used for the method for extruding the oil sludge: the method comprises the steps of firstly adhering an oil sludge material to a side wall metal plate seam allowance, then closing a vehicle door, closing the vehicle door, extruding the oil sludge by the metal plate of the vehicle door and the side wall seam allowance metal plate in a metallographic mode, reducing the thickness of the oil sludge to be the same as the gap value between the vehicle door and the side wall, opening the vehicle door, taking down the oil sludge, and measuring the thickness of the compressed oil sludge to obtain a sealing gap. However, the measurement method has three disadvantages, specifically as follows: when the sealing gap is measured, the oil sludge is easy to deform and irradiate into a measurement error due to the higher operation difficulty of the method; secondly, because the oil sludge has certain viscosity, when the oil sludge is taken down from the metal plate, the oil sludge is easy to partially remain on the metal plate, so that the light pollution of the metal plate paint surface of the vehicle body is caused, and the later cleaning is required; finally, as the sludge material is greatly influenced by the ambient temperature, the second defect is aggravated by the viscosity improvement at high temperature, the hardness improvement measurement at low temperature is not easy to deform, the measurement error is increased, and the four seasons of the indoor temperature of a factory are greatly changed, so that the sludge is inconvenient to operate on the production line.
