[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. After the tap completes a tapping operation, the cleaning head moves along the spiral tooth path on the tap. If the spiral tooth end of the tap absorbs debris after the tapping operation, the cleaning head cleans the debris by knocking it off. At the same time, lubricant is discharged from the cleaning head and applied to the tap to increase lubrication to avoid debris absorption in the next tapping operation.

[0015] 2. The present invention uses the reaction impact of debris on the baffle plate, and subsequent transmission causes the outer ring gear to rotate. The rotation of the outer ring gear will cause subsequent lubricant delivery and discharge work. After the debris is impacted, the baffle plate is pushed back to its original position, and then the rotation of the outer ring gear ends, and the lubricant delivery and discharge also ends automatically, thus avoiding waste of lubricant.

[0042] An intelligent tapping process for producing aluminum frames for new energy vehicles comprises the following steps: Step 1: After the aluminum frame is fixed on the workstation, multiple tapping devices on both sides of the workstation operate simultaneously, and the tap 2 in the tapping device is rotated and inserted into the prefabricated drilled hole on the aluminum frame. After the tapping is completed, the tap 2 is rotated in the opposite direction on the aluminum frame and pulled out; Step 2: The chip remover 6 is further controlled by the main control unit 7. The cleaning head 17 in the chip remover 6 moves downward in a spiral around the spiral teeth on the tap 2 to knock off the debris attached to the spiral teeth. After the cleaning head 17 moves to the end, it moves in the reverse direction to reset, and the screw end on the tap 2 is exposed. The tap 2 then performs the next tapping operation. Step 3: While the cleaning head 17 impacts the debris in the spiral teeth of the tap 2, the cleaning head 17 discharges lubricant to be applied to the spiral teeth of the tap 2. The tap 2 coated with lubricant has less absorption of debris in the next tapping operation; Step 4: If there is no debris adsorbed in the spiral tooth groove of the tap 2, the cleaning head 17 only performs a spiral motion, and the tap 2 is not coated with lubricant.

[0043] Figure 5 The Z-type plate 14 in the middle drives the cleaning head 17 in the spiral descent, and the cleaning head 17 moves around the spiral teeth on the tap 2. The walking plate 43 will knock off the debris attached to the spiral tooth groove to clean the tap 2. During the collision, the debris will impact the baffle plate 46 in the reverse direction. While the baffle plate 46 moves, it will transmit the inner shaft 49, and then transmit the outer shaft 53 through the branch shaft 51. The outer shaft 53 and the cam plate 52 rotate synchronously. The rotated cam plate 52 contacts the inner wall of the outer gear ring 18. At this time, the cam plate 52 moves around with the walking plate 43, thereby causing the outer gear ring 18 to rotate, and then the long cylinder gear 15 is driven to rotate through the lifting shaft 16, and then the speed reduction gear 41 is transmitted through the short worm 40, and then the horizontal shaft 35 is driven to rotate through the speed reduction shaft 42. Then the long worm 33 rotates to cause the pressure plate frame 37 to move. Figure 8 The pressure plate frame 37 in the middle descends to drive the sliding plate 39, and the sliding plate 39 slides and descends in the oil storage barrel 23 to squeeze the lubricant out of the oil storage barrel 23. After the lubricant is forced through the rubber nozzle 30, it is injected into the annular channel between the inner ring concave shell 28 and the outer ring cylinder 29 through the hose 32, and then injected into the V-shaped box 47 through the hard pipe 44, and penetrates and is discharged through the V-shaped sponge plate 48 to wipe and lubricate the spiral teeth on the tap 2.

[0044] The annular channel between the inner ring concave shell 28 and the outer ring cylinder 29 always exists, and the lubricant is transported between the hose 32 and the hard tube 44. The oil delivery tool 9 in the present invention does not move around the tap 2. The cleaning head 17, the C-shaped plate 20 and the inner ring concave shell 28 rotate outside the tap 2, and the outer ring gear 18 can rotate briefly. During the rotation, the cleaning head 17 discharges lubricant to the tap 2. After the impact ends, that is, the debris falls off the tap 2, and the reverse impact on the baffle plate 46 ends. The return spring 50 pushes the baffle plate 46 to reset. The subsequent rotation causes the cam plate 52 and the outer ring gear 18 to separate, and the outer ring gear 18 is not driven. Therefore, the outer ring gear 18 rotates briefly, and the rotation of the outer ring gear 18 ends, and the discharge of the lubricant ends.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
