A manufacturing method of tooling used for passenger car front windshield inspection and skin positioning

Abstract

The invention discloses a manufacturing method for a tool for passenger car foreside windscreen inspection and skin positioning. The manufacturing method for the tool comprises the steps of manufacturing a front wall main model, manufacturing a front wall skin positioning tool, manufacturing a foreside windscreen inspection tool and assembling the front wall skin positioning tool and the foreside windscreen inspection tool, wherein a frame of the front wall skin positioning tool and the foreside windscreen inspection tool is manufactured through rectangular tubes, and each seam allowance mold body is formed through angle iron cold forming. According to the manufacturing method, after the front wall main model and numerical control machining are adopted, the precision is good and serves as the standard, and according to the standard, the front wall skin positioning tool and the foreside windscreen inspection tool are manufactured; and the whole vehicle modeling effect can be improved effectively; the tool is made of common materials in a workshop, the structure is simple, manufacturing is facilitated, and the cost is saved; and the manufacturing method is easy and convenient to implement, implementation is facilitated, and the manufacturing efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of passenger car production, and in particular relates to a method for manufacturing tooling used for inspection of the front glass of a passenger car and skin positioning. Background technique [0002] With the rapid development of the domestic passenger car industry in recent years, passenger cars are gradually changing towards large-scale, luxury, and full load bearing. During this transformation process, the competitive pressure of the passenger car industry is increasing. The overall vehicle shape and the appearance quality of the front and rear panels have become more and more concerned issues for bus manufacturers. The front windshield of a passenger car is the facade of the passenger car, which requires high precision and dimensional quality; the installation quality of the passenger car skin not only affects the appearance of the vehicle, but also has an impact on the structural tightness of the pas...
