Screw rod notch gas detection surveys device

The utility model relates to a screw rod notch gas detection surveys device, include: detect seat, trachea and pressure detection part. It fixes on sending screw rod device through the mount pad to detect the seat, it is provided with the inspection hole of placing the screw rod to detect the seat, air supply equipment is connected to tracheal one end, and the terminal surface of placing the screw rod in the inspection hole can be hugged closely to the other end, the pressure detection part sets up on the trachea, can detect endotracheal pressure, unchangeable signal of output pressure or atmospheric pressure change signal. This gas detection surveys device application atmospheric pressure and detects the position of confirming spiral shell bar groove end, has improved automatic wrong screw rod equipment production efficiency greatly. 本实用新型涉及种螺杆槽口气检测装置，包括：检测座、气管及压力检测部件。检测座通过安装座固定在送螺杆装置上；检测座设置有放置螺杆的检测孔；气管的端连接供气设备，另端能紧贴放置于检测孔内的螺杆的端面；压力检测部件设置在气管上，能检测气管内的压力，输出气压不变信号或气压改变信号。该气检测装置运用气压检测来确定螺杆凹槽端的位置，大大提高了自动拧螺杆设备生产效率
