Remaining amount detection device for frame structural member processing

A margin detection device for frame structural member processing relates to the technical field of frame structural member processing, a guide mechanism is installed in a groove, a detection mechanism is installed on a rod body, the detection mechanism is located on the upper side of the guide mechanism, rotating rods are arranged in the groove at equal intervals and rotatably connected, and guide wheels are fixedly connected to the rotating rods. The wheel face of the guide wheel is flush with the face, provided with the groove, of the rod body, the number of the sliding rods is two, and the two sliding rods are both located on the rod body and connected with the rod body in a sliding mode. According to the technical scheme of the utility model, the margin detection device for processing the frame structural member can move along the edge of the frame structure conveniently through the guide mechanism, and the position of the rod body is limited through the limiting plate, so that the edge of the frame struc
