During detection, the armrest 30 is fixed on the armrest positioning mechanism 10, and then the armrest cover 22 is flipped and covered on the armrest 30. If the reference line is aligned with the sewing thread of the armrest 30, it is considered that the sewing thread is qualified; otherwise, it is considered that there is a deviation.
[0026] This application provides an armrest 30 stitching detection fixture, which includes an armrest positioning mechanism 10 and a stitching detection mechanism 20; the armrest positioning mechanism 10 includes a bottom plate 11 and a positioning plate 12 arranged on the bottom plate 11, and the armrest 30 can be fixed to the positioning plate 12; the stitching detection mechanism 20 includes a flipping frame 21 and an armrest cover 22 arranged on the flipping frame 21; the armrest cover 22 is transparent or semi-transparent; a reference line 29 is arranged on the armrest cover 22; the armrest cover 22 can be flipped to cover the armrest 30, and the reference line is aligned with the stitching of the armrest 30. In this embodiment, the bottom plate 11 is vertically arranged on the positioning plate 12, and there is a certain gap between the positioning plate 12 and the bottom plate 11. During detection, the worker fixes the armrest 30 on the armrest positioning mechanism 10, then flips the armrest cover 22 to cover the armrest 30, and if the reference line is aligned with the stitching of the armrest 30, it is considered that the stitching position is accurate and the quality is excellent. Of course, a deviation within a certain range between the reference line and the stitching is also qualified, and only multiple reference lines need to be set correspondingly. That is, each reference line corresponds to a different detection result, such as excellent, qualified, unqualified, etc. It can be seen that the worker can detect with this fixture with high efficiency, reduced detection difficulty, and good accuracy.
