Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cutting tooling, and in particular to a track jig for cutting lifting lugs. Background Art
[0002] During shipbuilding, temporary lifting lugs are often used to transfer processed components and equipment to the next process. This facilitates lifting operations, improves efficiency, and shortens the construction cycle. However, most of these lifting lugs need to be removed after use. Manual removal, however, is limited by the operator's skill level, and often requires significant time-consuming polishing after cutting. For example, after the motherboard is assembled, it needs to be lifted from the automated welding platen onto the frame. Four lifting lugs are typically installed on the motherboard, and these need to be removed after the lifting is complete. After removal, the cut surface needs to be polished smooth.
[0003] In order to solve this problem, the use of automated or semi-automated equipment was considered to improve cutting accuracy. After investigation and trial, it was found that most of the equipment on the market had problems such as frequent disassembly, cumbersome operation, and heavy weight. Utility Model Content
