[0031] Working principle: In this embodiment, the present invention also proposes a method for using an automatic tapping machine with a cooling oil recycling function, comprising the following steps:

[0032] Step 1, first connect all electrical equipment to the wires and power on, then put the workpiece to be processed into the loading tray 5, start the loading tray 5, and vibrate the loading tray 5 to load the workpiece, so as to control the workpiece to enter the arc guide rail 6. When the workpiece enters the arc guide rail 6, the workpiece will slide to the lower end of the arc guide rail 6, and then enter the movable table 28 through the installation port 29, and then start the second electric push rod 27, and push the movable table 28 by the second electric push rod 27, so as to move the movable table 28 to the rear end of the L-shaped guide rail 24, and then start the first electric push rod 25. When the first electric push rod 25 is started, the push block 26 is controlled to move, and then the workpiece in the movable table 28 is pushed to the bottom of the tapping head, and then the spacing between the limit plates 36 on both sides is adjusted according to the size of the workpiece, and then the limit plates 36 are fixed by the hexagon socket bolts 38;

[0033] Step 2, when the workpiece is pushed to the bottom of the tapping head, the driving cylinder 9 is started, and the rack 8 and the driven gear 11 are meshed and transmitted, and then the driven gear 11 and the driving shaft 12 are fixedly connected. When the driving cylinder 9 is started, the lifting of the rack 8 is controlled, and then the rotation of the driven gear 11 is controlled, thereby controlling the rotation of the driving shaft 12, and the driving shaft 12 is connected to the first universal joint 13, and then the first universal joint 13 is connected to the second universal joint 16 through the spline shaft 14 and the spline sleeve 15. When the driving shaft 12 rotates, The first universal joint 13 is controlled to rotate, and then the second universal joint 16 is controlled to rotate. The second universal joint 16 is connected to the driven shaft 17, and then the driven shaft 17 is fixed to the driving bevel gear 19. The driving bevel gear 19 and the driven bevel gear 20 are meshed and transmitted. When the second universal joint 16 rotates, the driving bevel gear 19 is controlled to rotate, and then the driven bevel gear 20 is controlled to rotate, thereby controlling the rotation shaft 21 to rotate, and then the tapping head is controlled to rotate. When the driving cylinder 9 controls the rack 8 to rise and fall, the tapping head is controlled to rotate forward and reverse.

[0034] Step three, when the tapping head rotates forward, the output shaft of the lifting cylinder 22 is started to descend, thereby controlling the transmission box 18 to descend, and then controlling the tapping head to descend, so as to control the tapping head to tap the workpiece; when the tapping head is reversed, the output shaft of the lifting cylinder 22 is started to rise, thereby controlling the transmission box 18 to rise, and then controlling the tapping head to rise, so as to control the tapping head to be taken out, so as to facilitate the subsequent tapping of other workpieces; when the transmission box 18 rises and falls, the spline shaft 14 and the spline sleeve 15 on the other side will be extended and retracted with the rise and fall of the transmission box 18;

[0035] Step 4, when the tapping head is tapping, the water pump 43 is started, and the cooling oil in the collection tank 44 is extracted by the water pump 43, so that the cooling oil is guided to the nozzle 40 through the first connecting pipe 41 and the second connecting pipe 42, and then the cooling oil is sprayed on the tapping head and the workpiece through the nozzle 40. When the workpiece is processed, the processed workpiece is ejected through the workpiece at the rear end. At this time, the processed workpiece first contacts the limiting wheels 33 on both sides. When the workpiece continues to move forward, the limiting wheels 33 on both sides will move to both sides. At this time, the spring 35 is in a compressed state. When the workpiece is ejected, the limiting wheel 33 is reset by the spring 35, so that the next workpiece is limited; when the workpiece is ejected, the workpiece will carry part of the cooling oil into the collection box 45, and the workpiece and the cooling oil will be separated by the filter 46. The cooling oil will enter the collection tank 44 and then be extracted by the water pump 43, so as to achieve the purpose of circulation;

[0036] Step 5, when the workpiece processing is completed, the collection box 45 is taken out through the handle 47, and then the processed workpiece is taken out from the collection box 45, and then all electrical equipment is powered off.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
