The automatic female thread making apparatus of the present invention, including bearing and be located at the motor on bearing, drive mechanism, for clamping the fixture of workpiece and for workpiece being carried out the cutter of tapping, described drive mechanism includes power transmission shaft, described motor drives cutter to rotate by power transmission shaft, being provided with linear actuators between described fixture and bearing, described linear actuators promotes fixture to tool motion；Described power transmission shaft includes the driving shaft for being connected and the driven shaft for being connected with cutter with motor, and described driving shaft is connected by release mechanism with driven shaft；Secondary flange that the main flange that described release mechanism includes being connected with described driving shaft is connected with described driven shaft and steel ball, described main flange is respectively equipped with corresponding status of a sovereign hole and secondary hole, position with the end face of secondary flange, described steel ball snaps in described status of a sovereign hole and secondary hole, position to connect described driving shaft and driven shaft, described secondary flange is additionally provided with and sets female adjustment hole with described secondary hole, position connects, described adjustment hole is equipped with adjusting bolt, between described steel ball and adjusting bolt, is provided with spring。
Beneficial effects of the present invention: the automatic female thread making apparatus of the present invention, power transmission shaft is divided into two sections and is connected by the release mechanism newly established, when cutter is produced bigger resistance by workpiece, release mechanism produces skidding effect, namely when the transmission moment between driving shaft and driven shaft exceeds moment set in advance between main flange and secondary flange, transmission between main flange and secondary flange disengages, to stop transmission process, now motor still autobiography, it is prevented that the damage of motor and other component；To namely can proceed with tapping after removal of obstacle, it is ensured that being smoothed out of tapping operation, improve working performance；Default moment between main flange and secondary flange is then determined by the elastic force of spring, easy to adjust, reliable；Put motion by linear actuator drives fixture to cutter, be conducive to keeping the stability of cutter, it is ensured that Tapping Quality。
As further improvement, being provided with support platform between described fixture and linear actuators, the output shaft of described linear actuators is fixing with support platform to be connected；By supporting platform support fixture, it is ensured that the accuracy of clamp movement。
As further improvement, described drive mechanism also includes gear-box, and the output shaft of described motor is in transmission connection by the gear in gear-box and driving shaft；Gear drive makes the arrangement of motor more diversified, it is achieved the compactedness requirement of this device；Meanwhile, the concrete model of the gear by matching selects also to realize multiple speed change。
As further improvement, described drive mechanism also includes being fixed on the axle box bottom described gear-box, and described power transmission shaft is located in axle box；Axle box protection power transmission shaft and release mechanism, make this device more robust, increase the service life。
As further improvement, the longitudinal direction front side of described bearing is provided with vertical column, and described motor, gear-box and axle box are connected each through connecting plate and column are fixing；This fixing connection can be welding or be spirally connected, and reduces the vibrations of motor, it is ensured that cutter is stable。
