Description

Technical Field

[0001] The utility model relates to the technical field of end cap processing, and more particularly to a positioning device for grinding and processing the end cap surface. Background Art

[0002] A head, also known as an end cap, is used to seal the end of a container, isolating the internal and external media. The head of a cylindrical container is generally a revolving shell. Based on the shape of the head surface, it can be categorized as convex, conical, flat, or combined. Convex heads are those with a convex outer surface, such as hemispherical, elliptical, dished, and flat spherical heads. During the grinding process, a positioning device is required to secure the head.

[0003] However, most of the existing positioning devices have a relatively simple structure and do not have the function of freely adjusting the angle of the head. As a result, when different positions on the head need to be polished, the head needs to be moved frequently, which affects the polishing efficiency.

[0004] Moreover, most of the positioning structures are one-piece molding settings, and the clamping blocks cannot be disassembled and replaced, resulting in them not being applicable when positioning heads of different sizes, and the stability is also poor, which affects the normal progress of subsequent grinding.
