[0038] Refer to Figure 1-14 ,

[0039] A tapping and tail-cutting integrated machine for processing screws, comprising: a frame 1, a cutting member 2, a clamping plate 3, a power member 4, a first transmission member 5, a die 6, a driving member 7, a second transmission member 8, a connecting plate 9 and a pushing member 10. The cutting member 2 includes a circular saw machine 11 and an electric push rod 12. The saw blade of the circular saw machine 11 faces downward and the fixed end faces upward. The fixed end of the circular saw machine 11 is bolted to the output end of the electric push rod 12, and the fixed end of the electric push rod 12 is bolted to the frame 1. Two clamping plates 3 are provided, and the two clamping plates 3 are placed on the frame 1 below the circular saw machine 11. The power member 4 is a first motor. The first transmission member 5 includes a lead screw 13, a nut 14 and a transmission block 15. A rotating frame 16 is formed on the frame 1. The lead screw 13 is rotatably connected to the rotating frame 16. The housing of the power member 4 is bolted to the rotating frame 16. The output end of the power member 4 is connected to one end of the lead screw 13 through a coupling. The nut 14 is threadedly connected to the lead screw 13. The nut 14 is fixed to the clamping plate 3 through the transmission block 15. The power member 4 causes the two clamping plates 3 to merge and separate from each other through the lead screw 13, the nut 14 and the transmission block 15 in sequence. A blank 17 is arranged between the two clamping plates 3. The blank 17 includes a nut 18 and a screw rod 19. When the two clamping plates 3 merge, the two clamping plates 3 clamp the nut 18 of the blank 17 upward and the screw rod 19 downward. An installation groove 20 is formed on the frame 1 below the clamping plate 3. The pushing member 10 is a cylinder. The housing of the pushing member 10 is bolted to the bottom surface of the installation groove 20. The output end of the pushing member 10 is bolted to the bottom surface of the connecting plate 9. The driving member 7 is a second motor. The housing of the driving member 7 is bolted to the upper surface of the connecting plate 9. The second transmission member 8 includes a small gear 21, a large gear 22, a rotating shaft 23, a turntable 24, a mounting bracket 25 and a plug rod 26. The lower end of the rotating shaft 23 is fixed to the upper surface of the connecting plate 9. The upper end of the rotating shaft 23 is rotatably connected to the lower surface of the turntable 24. The large gear 22 is sleeved on the circumference of the turntable 24 through a flat key. The small gear 21 is connected to the output end of the driving member 7 through a flat key. The small gear 21 and the large gear 22 are meshed. The mounting bracket 25 is welded to the upper surface of the turntable 24. A jack is formed on the mounting bracket 25. The die 6 is fixed to the plug rod 26 installed in the jack. The pushing member 10 causes the connecting plate 9 to rise and fall, so that the die 6 contacts the screw rod 19. The driving member 7 causes the die 6 to rotate through the second transmission member 8 to tap the screw rod 19. The cutting of the nut 18 by the cutting member 2 and the tapping of the screw rod 19 by the die 6 are carried out simultaneously.

[0040] Specifically, clamping grooves 27 are formed on the opposite end faces of the two clamping plates 3. The clamping grooves 27 penetrate through the two opposite vertical faces of the clamping plates 3, and the nuts 18 are clamped in the clamping grooves 27. Fixing grooves 28 are formed below the two clamping plates 3. When the two clamping plates 3 are combined, the two fixing grooves 28 are combined into a circular groove and are in circumferential fit with the screw rod 19. A part of the screw rod 19 passes through the fixing groove 28 and extends into the installation groove 20 below. Yielding grooves 29 are formed above the two clamping plates 3. The lower part of the saw blade of the circular sawing machine 11 can pass through the yielding grooves 29 to cut a groove in the upper end of the nut 18.

[0041] Specifically, the projection of the installation groove 20 on the ground coincides with the projection of the connecting plate 9 on the ground, and the installation groove 20 guides the connecting plate 9 moving up and down.

[0042] Specifically, the mounting bracket 25 includes two columns 30 and a support plate 31. The two columns 30 are opposite to each other and are separated on both sides of the die head 6. The lower ends of the two columns 30 are welded to the turntable 24. The support plate 31 is welded between the two columns 30. The height of the two columns 30 is greater than the length of the screw rod 19 that needs to be tapped. A round hole is formed in the middle of the support plate 31, and its diameter is greater than the diameter of the screw rod 19 to facilitate the screw rod 19 passing through the support plate 31. The lower surface of the die head 6 is closely attached to the upper surface of the support plate 31. The die head 6 is clamped between the two groups of columns 30, and the support plate 31 plays a supporting role when the die head 6 taps the screw rod 19.

[0043] Specifically, the two clamping plates 3 cover a part above the installation groove 20, and the other part forms an opening 32 for yielding to the driving member 7 when the driving member 7 is lifted by the pushing member 10 through the connecting plate 9.

[0044] Specifically, a maintenance hole 33 and a maintenance door 34 are provided in the lower half of the machine frame 1. The maintenance hole 33 penetrates through one side of the machine frame 1 and communicates with the installation groove 20. The maintenance door 34 is installed beside the maintenance hole 33 through a hinge and covers the maintenance hole 33.

[0045] Specifically, permanent magnets are provided on the surfaces of the clamping grooves 27 and the fixing grooves 28 to prevent the blanks 17 on the clamping plates 3 from falling off when the two clamping plates 3 are separated.

[0046] Working process: The power member 4 sequentially separates the two clamping plates 3 through the lead screw 13, the nut 14 and the connecting block, manually clamps the nut 18 of the blank 17 into the clamping groove 27 of a clamping plate 3, and makes the screw 19 pass through the fixing groove 28. The permanent magnets on the clamping groove 27 and the fixing groove 28 attract the blank 17. The power member 4 then merges the two clamping plates 3 through the first transmission member 5, and the blank 17 is stably fixed by the two clamping plates 3. The cutting member 2, the push member 10 and the driving member 7 are started, and the electric push rod 12 moves the circular saw machine 11 downward, so that a part of the saw blade passes through the clearance groove 29 to cut the upper end of the nut 18. The push member 10 moves the driving member 7, the second transmission member 8 and the die 6 upward through the connecting plate 9. The driving member 7 rotates the die 6 forward around the axis of the screw 19 through the second transmission member 8, and the die 6 taps the screw 19 when it contacts it. As the die 6 moves upward, the lower end of the screw 19 also moves downward through the support plate 31. After the grooving and tapping are completed, the cutting member 2 moves upward to disengage from the clamping plate 3, the driving member 7 rotates the die 6 in the opposite direction through the second transmission member 8, and the pushing member 10 moves the connecting plate 9 downward until the die 6 disengages from the screw 19. The power member 4 separates the two clamping plates 3 through the first transmission member 5. Due to the attraction of the permanent magnet, the finished screw will not fall off the clamping plate 3, and the finished screw is removed manually.

[0047] When the parts in the installation slot 20 are damaged, the inspection door 34 can be opened and the parts in the installation slot 20 can be repaired and replaced through the inspection hole 33.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above invention concept.
