Description

Technical Field

[0001] The present invention relates to the technical field of machining, and more particularly to an integrated device for fastener tapping, oil removal and iron chip separation. Background Art

[0002] Nuts, also known as nuts, are a kind of fixing tool with a hole in the center and threads on the inside of the hole. Nuts are often used with matching bolts to fix the related joint parts. Nuts are mostly hexagonal, followed by squares. In the manufacturing process of nuts, in order to be able to thread with bolts, it is necessary to process the inner hole of the nut with internal threads. The most widely used internal thread processing machine is generally a nut tapping machine. The automatic nut tapping machine is a machine that processes internal threads on the inner side of the hole of various parts with through holes or blind holes of various specifications such as nuts and flanges. Nut tapping machines are also called nut tapping machines, nut tapping machines, automatic nut tapping machines, fully automatic nut tapping machines, tapping machines, and tapping machines. They are called nut tapping machines in the south and nut tapping machines in the north.

[0049] The tapping, chip separation and oil removal process of the integrated device for fastener tapping, oil removal and chip separation is as follows:

[0050] 1) A plurality of nuts are conveyed onto the nut feeding plate 7, and the rotating nut feeding plate 7 applies centripetal force to the nuts, so that the nuts move one by one onto the feeding spiral plate 4 to the feeding relay groove;

[0051] 2) The nuts fed into the nut pushing receiving tube 10 through the feeding relay slot are pushed one by one to the other end of the nut pushing receiving tube 10 by the pushing force rod 11;

[0052] 3) The nut that has entered the other end of the nut push-in tube 10 is pushed into the tapping tube 16 by the nut positioning member, and when the other end of the nut push-in tube 10 and the tapping tube 16 are filled, the nut at the front end of the tapping tube 16 contacts the front end of the tap 28;

[0053] 4) When the pushing force rod 11 pushes the nut toward the other end of the nut pushing socket 10, the nut in the other end of the nut pushing socket 10 and in the tapping socket 16 is squeezed, so that the frontmost nut applies pressure to the tap 28. At this time, the high-speed rotating tap 28 taps the nut;

[0054] 5) In the early stage of tapping a nut by the tap 28, the nut needs to apply a large pressure to the tap 28. In the middle and late stages of tapping a nut, it is not necessary to apply too much pressure. At this time, the pushing force rod 11 is retracted, and the next nut is ready to be pushed. As the pushing force rod 11 is retracted, the pre-tightening tongue 15 is inserted into the nut pushing receiving tube 10 by the pushing force of the first pre-tightening spring 13, and the side surface of the pre-tightening tongue 15 is against the end surface of the nut. As the pre-tightening tongue 15 is pushed by the second pre-tightening spring 14, the pre-tightening tongue 15 applies pressure to the nut toward the other end of the nut pushing receiving tube 10, thereby satisfying the mutual pressure between the tap 28 in the middle and late stages of tapping a nut.

[0055] 6) When the tap 28 is tapping the nut, the cooling lubricant is continuously delivered by the liquid supply pump to the first cooling lubricant through hole, and then sprayed to the inner side of the nut from the second cooling lubricant through hole, so as to improve the cooling and lubrication efficiency of the tap 28; at the same time, the cooling lubricant can timely flush the iron chips from the tapping out from one end of the tapping receiving tube 16, so as to further reduce the wear of the tap 28 and improve the tapping quality;

[0056] 7) With the assistance of the pre-tightening tongue 15, the nut in the tapping receiving tube 16 continuously applies pressure to and moves the tap 28, thereby achieving continuous tapping of the nut;

[0057] 8) The nut after tapping passes through the tap 28 and is sleeved on the tapping driven transmission rod 27. The nut sleeved on the tapping driven transmission rod is subjected to the axial thrust from the side of the transmission plate 26, so that the nut moves toward the other end of the tapping driven transmission rod 27;

[0058] 9) When the nut moves to the other end of the tapping transmission rod, the second quick male connector 43 is inserted into the second quick female connector, and the first quick male connector 42 is pulled out of the first quick female connector 38, and the nut passes over the rotary connector 33 to the elbow 34;

[0059] 10) The first quick male connector 42 is inserted into the first quick female connector 38, and the second quick male connector 43 is pulled out from the second quick female connector, so that the nut passes over the liquid supply connector and falls into the nut degreasing part for degreasing;

[0060] 11) After the nut is degreased, it can be sent out through the nut conveyor.
