The present invention and its advantages: the operation steps of the nut tapping device for processing fire accessories are as follows:

Step 1: First, close the valve on the oil guide pipe 18, then pour the lubricating oil into the oil storage tank 17, and then set the sensing distance of the proximity switch 16, such as between the sensing surface of the proximity switch 16 and the side baffle 15 If the vertical distance is 15cm, the sensing distance of the proximity switch 16 can be set to 16cm, and the proximity switch 16 can be set to the normally open state, that is, when there is no obstruction in front of the proximity switch 16, the proximity switch 16 will control the solenoid valve 21 to close automatically. When there is an obstruction in front of it, the proximity switch 16 will control the solenoid valve 21 to automatically open, so as to complete the automatic control setting.

Step 2: Rotate the turntable 6, turn one of the slots 8 to just below the tap 14, use a measuring tool to assist in positioning, and then rotate the threaded rod 23 inwards, so that it is firmly squeezed against the extrusion block 24. on the turntable 6, so that the turntable 6 can be quickly fixed.

Step 3: As shown in Figure 2, put the original nut in the placement groove 7 under the tap 14, open the valve on the oil guide pipe 18, first turn on the motor 12 to rotate at high speed with the tap 14, and then open the cylinder 9 to let it carry The motor 12 and the tap 14 descend. When the motor 12 descends, the side baffle 15 on the pressure plate 11 will also descend accordingly. When the side baffle 15 is lowered to the front of the proximity switch 16, the circuit controlled by the proximity switch 16 automatically closed, that is, the solenoid valve 21 is automatically opened. At this time, the lubricating oil in the oil storage cylinder 17 flows out through the oil guide pipe 18, the oil guide plate 19 and the hose 20, and finally flows from the hose 20 to the tap 14, so as to automatically Apply oil and lubricate. When the tap 14 is in contact with the original nut, the thread will be tapped on the original. After the original is tapped through, the tap 14 will protrude from the slot 8 to complete the tapping process. When tapping, the spring 27 starts To achieve a good buffering and vibration damping function, reduce the probability of the tap 14 breaking, which is beneficial to protect the tap 14 and improve the stability and protection during tapping. After the tapping is completed, retract the cylinder 9 to let the tap 14 from the nut. At the same time, the side baffle 15 will also rise. After the side baffle 15 is removed from the front of the proximity switch 16, the solenoid valve 21 controlled by the proximity switch 16 will automatically close and stop oiling, thereby realizing the function of automatic oiling. , and finally remove the processed nut from the placement slot 7.
