Description

Technical Field

[0001] The present application relates to the technical field of assembly and positioning tooling for frameless vehicle doors, and in particular to a simplified positioning device and positioning method for frameless vehicle door glass. Background Art

[0002] As a unique design element, frameless doors have been increasingly used in the market in recent years, especially in the field of new energy vehicles. Frameless doors have become a plus point for vehicle styling, and the assembly rate is increasing rapidly. Frameless doors eliminate the traditional frame in appearance, allowing the door and the body to fit seamlessly, thereby improving the fashion sense and aesthetics of the entire vehicle.

[0003] Since frameless doors have no frames, the door glass assembly is more difficult. The common method of assembling frameless door glass is to achieve positioning through a complex pneumatic control tooling. The specific plan is: the glass lifter is self-positioned and assembled through the studs on the guide rail and the sheet metal holes on the door sheet metal assembly, and then the door sheet metal assembly with the installed glass lifter is positioned on the tooling, and then the tooling is operated to make the tooling hold the door and glass tightly, tighten the lifter glass clamp and the glass, and release the tooling. In the process of positioning the door sheet metal assembly with the installed glass lifter on the tooling, the tooling provides positioning for the door sheet metal assembly and the glass in the three directions of X, Y, and Z respectively, and the door sheet metal assembly and the glass positioned in the three directions can be accurately positioned and installed.

[0004] Because the door sheet metal assembly and the door glass positioning assembly after the glass lifter are installed require tooling, common tooling is large in size and usually uses multiple workstations temporarily.
