Technical Field
The invention relates to the technical field of automobile door assembly checking tools, in particular to a sample preparation frame for a manual device of a door sealing strip and a preparation method of the sample preparation frame.
Background
At present, sealing strip parts with different cross-section forms are stuck to the side face of an automobile door in a circle, the airtightness of an automobile body is enhanced, the noise generated during the running of the automobile is expected to be reduced, and the sealing strip part is a common means for improving the NVH performance of the whole automobile.
The installation of the sealing strip mainly comprises three technical means, namely full-automatic assembly (completely assembled by a robot), semi-automatic assembly (man-machine matching assembly) and pure manual assembly. However, in any of the fitting means, a manual fitting tool for copying is indispensable. Under the automatic equipment abnormal conditions, operating personnel carries manual assembly tool and places on the panel beating of door, utilizes the imitative type curved surface of this instrument to carry out pasting and the roll extrusion of sealing strip, satisfies the product assembly requirement, ensures that the scene can not cause the shut down because of automation equipment goes wrong.
The conventional manual copying tool is generally made of a material with high rigidity, such as carbon fiber or cast iron. The carbon fiber sample preparation frame is light, high in precision, high in rigidity and high in size precision +/-1.0 mm, a profiling mold needs to be machined in the early stage, the manufacturing cost is high, the machining period is long, the process control is complex, and the requirements on the design and production capacity of suppliers are strict.
The manufacturing of the cast iron sample preparation frame also needs to use a mold for copying and then subsequent machining treatment, the size precision can be controlled to be +/-1.0 mm, the cost is high, the self weight is high, an independent storage rack needs to be arranged, a single person cannot carry the cast iron sample preparation frame during use, the human-computer environment is poor, and the workshop acceptability is very low.
Meanwhile, because the outlines of different vehicle types are different, the carbon fiber and cast iron used in the former period can not be reused on other vehicle type products, belong to byproducts in the production and manufacturing process, have no use value any more, and are one of the important reasons for high cost enterprises of the two processing modes.
