Problems solved by technology
After stretch forming of skin-like parts, it is difficult to accurately measure the linear deformation along the stretching direction. Conventional tools can only select a few specific measurement points on the skin to observe the local stretching amount, and cannot realize the entire stretching direction. For the measurement of the stretching amount in the full range, the conventional method of manually using a marker pen to draw a line can meet the above requirements, but the operation time is long, the accuracy is low, and the efficiency is low.

Description
technical field [0001] The invention belongs to the technical field of forming and manufacturing of sheet metal parts, and in particular relates to a flexible measuring tape for stretching deformation of skin and a method for using the same. Background technique [0002] Skin stretch forming is a typical skin part forming method in the field of aviation manufacturing. It is a process method in which the edge of the sheet is clamped by the skin stretching equipment and stretched along the surface of the stretch die. After stretch forming of skin-like parts, it is difficult to accurately measure the linear deformation along the stretching direction. Conventional tools can only select a few specific measurement points on the skin to observe the local stretching amount, and cannot realize the entire stretching direction. For the measurement of the stretching amount in the full range, the conventional method of manually using a marker pen to draw a line can meet the above require...
