[0001] The utility model relates to the technical field of automobile workpiece manufacturing, in particular to a device for positioning the sewing edge of a skin in a frame groove of a frame. Background Art

[0002] Automotive interiors are automotive products used inside cars. Their production process is generally to cover the formed automotive workpiece with leather and other materials of a specific material to form the final automotive interior product. The skeleton structure is complex, with concave and inclined bevels with large areas and stepped corners with small dimensions. The hemming of these locations is very difficult. In addition, for aesthetic considerations, the covering surface usually has sewing lines such as decorative lines. Due to the large size of the skeleton, the sewing lines are long and usually have a certain curvature. During the covering process, they are easily twisted or displaced due to force.
