[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] A fully automatic tapping device for cold heading machine, such as Figures 1 to 10As shown, it includes a frame 1, a material guide tube 11, a material discharge seat 12, a material dividing member 2, two material pushing members 3, two material guide tubes 13, two material discharge seats 14, a material dividing member 4, a plurality of clamping members 5, a plurality of tapping members 6 and a plurality of pushing members 7. In this embodiment, the number of the clamping members 5, the tapping members 6 and the pushing members 7 are all four and correspond to each other.

[0032] like Figure 1 to Figure 2 As shown, the cold heading machine has a rotating output terminal 8, and the rotating output terminal 8 is transmission-connected with a dividing piece 2, two pushing pieces 3, a dividing piece 4, a plurality of clamping pieces 5, a plurality of tapping pieces 6 and a plurality of pushing pieces 7. It should be noted that how to rotate the rotating output terminal 8 through a corresponding transmission structure by means of a rotating driving source in the cold heading machine belongs to the prior art and will not be elaborated on.

[0033] like Figure 2 , Figure 3 as well as Figure 5 As shown, the material guide pipe 11 connects the discharge end of the cold heading machine with the discharge seat 12. Specifically, the discharge seat 12 is provided with a material trough 121 for accommodating workpieces. The material guide pipe 11 is penetrated through the discharge seat 12, and the material guide pipe 11 is aligned with the material trough 121, that is, the workpiece produced by the cold heading machine can enter the material trough 121 through the material guide pipe 11. Furthermore, a material blocking block 122 is provided in the material trough 121, and the workpiece is blocked by the material blocking block 122, thereby preventing the workpiece from falling out of the material trough 121.

[0034] like Figure 3 to Figure 4 As shown, the material dividing component 2 is used to push the workpiece on the discharge seat 12 to align it with the guide tube 13. Specifically, the material dividing component 2 includes a material dividing cam 21, a material dividing rocker rod 22, a material dividing pull rod 23, a connecting ring 24, a material dividing spring rod 25, a return spring 26, a guide rod 27, two support seats 28, a support seat 29, a material dividing push plate 210, a transition shaft 211 and a bearing 212.

[0035] The dividing cam 21 is rotatably set on the frame 1 and is connected to the rotating output end 8. It should be noted that the rotating output end 8 is connected to the rotating shaft of the dividing cam 21 through two gear meshing transmissions, so that the rotating output end 8 can drive the dividing cam 21 to rotate, and the middle part of the dividing rocker arm 22 is rotatably connected to the frame 1, the transition shaft 211 is threadedly connected to the lower end of the dividing rocker arm 22, and the bearing 212 is installed on the transition shaft 211. The outer ring of the bearing 212 can abut against the outer side wall of the dividing cam 21. As the dividing cam 21 rotates, the outer side wall of the dividing cam 21 contacts the outer ring of the bearing 212, and the dividing cam 21 transmits the thrust to the dividing rocker arm 22 through the transition shaft 211, so that the dividing rocker arm 22 rotates.

[0036] The material dividing rocker arm 22 is rotatably connected with the material dividing pull rod 23, the two ends of the material dividing spring rod 25 are respectively mounted on the corresponding support seats 28, the connecting ring 24 is arranged on the outer wall of the material dividing spring rod 25, the material dividing pull rod 23 is connected with the material dividing spring rod 25 through the connecting ring 24, the two ends of the guide rod 27 are respectively mounted on the corresponding support seats 28, the support 29 is arranged on the material discharge seat 12, the guide rod 27 is slidably arranged on the support 29, the material dividing push plate 210 is connected with the guide rod 27, the material dividing push plate 210 passes through the material blocking block 122 and is located in the material trough 121, the reset spring 26 is sleeved on the outer wall of the guide rod 27, and the support seat 28 can cooperate with the support 29 to squeeze the reset spring 26.

[0037] It should be noted that, as the material dividing cam 21 rotates, the material dividing rocker 22 rotates, and the material dividing rocker 22 drives the material dividing spring rod 25, the support seat 28 and the guide rod 27 to move through the material dividing pull rod 23 and the connecting ring 24. At the same time, the support seat 28 cooperates with the support seat 29 to squeeze the return spring 26, and the guide rod 27 drives the material dividing push plate 210 to move along the material trough 121, and the material dividing push plate 210 pushes the workpiece to one side of the material trough 121 to make it face the material dividing push plate 210. The dividing cam 21 is aligned with one of the material guide tubes 213. As the dividing cam 21 continues to rotate, the thrust applied to the dividing rocker arm 22 disappears, and the elastic force generated by the reset spring 26 acts on the support seat 28. The support seat 28 drives the guide rod 27 and the dividing spring rod 25 to move. The guide rod 27 drives the dividing push plate 210 to move along the material trough 121. The dividing push plate 210 pushes the workpiece to the other side of the material trough 121 to align it with the other material guide tube 213.

[0038] like Figure 6 to Figure 7 As shown, two material guide pipes 13 are respectively connected to the material discharge seat 12 and the corresponding material discharge seat 14. Specifically, one end of the material guide pipe 13 extends into the material trough 121, and the material guide pipe 13 corresponds to the material discharge seat 14 one by one. The material discharge seat 14 is provided with a material trough 141 for accommodating workpieces, and the other end of the material guide pipe 13 is passed through the material discharge seat 14, that is, the workpiece in the material trough 121 can reach the material discharge seat 14 through the material guide pipe 13. Furthermore, the material discharge seat 14 is provided with a blocking block 142, which blocks the workpiece by the blocking block 142, thereby preventing the workpiece from falling out of the material discharge seat 14.

[0039] like Figure 3As shown, the two pushers 3 are respectively used to push the workpieces in the corresponding guide tube 13 toward the direction close to the discharge seat 14. Specifically, the pusher 3 includes an ejector cam 31, an ejector rod 32, an ejector needle 33, an ejector screw 34, an ejector screw sleeve 35, a limit nut 36 and a reset spring 37. The ejector cam 31 is rotatably set on the frame 1 and is transmission-connected with the rotary output end 8. It should be noted that the rotary output end 8 is transmission-connected with the rotating shaft of the ejector cam 31 through two gear meshings, so that the rotary output end 8 can drive the ejector cam 31 to rotate.

[0040] The middle part of the ejector rod 32 is rotatably connected to the frame 1, the ejector screw 1 34 is installed on the upper end of the ejector rod 32, the ejector needle 33 is installed on the ejector screw 1 34 and aligned with the guide tube 2 13, the ejector screw sleeve 1 35 is penetrated on the discharge seat 12, the return spring 2 37 is arranged between the ejector screw 1 34 and the limit nut 1 36, and the return spring 2 37 is sleeved on the ejector screw sleeve 1 35, the limit nut 1 36 is threadedly connected to the ejector screw sleeve 1 35, and the return spring 2 37 is connected to the limit nut 1 36.

[0041] The rotation of the ejector cam 31 can push the ejector rod 32 to rotate, so that the ejector pin 33 pushes the workpiece toward the guide tube 13. Specifically, the protruding portion of the ejector cam 31 contacts the lower end of the ejector rod 32, exerting a thrust on the ejector rod 32, thereby pushing the ejector rod 32 to rotate. The ejector rod 32 drives the ejector screw 1 34 and the ejector pin 33 to move toward the direction close to the guide tube 13. At the same time, the ejector screw 1 34 also cooperates with the limit nut 1 36 to squeeze the return spring 2 37. The return spring 2 37 is in a compressed state, and the ejector 32 is ejected. The needle 33 passes through the ejector screw sleeve 1 35 to push the workpiece to move, and the workpiece pushes the adjacent workpiece to move in turn, so that the front workpiece disengages from the guide tube 2 13 and reaches the discharge seat 2 14. As the ejector cam 31 continues to rotate, the protruding part of the ejector cam 31 disengages from the ejector rod 32, and the thrust applied to the ejector rod 32 disappears. At this time, the elastic restoring force of the reset spring 2 37 pushes the ejector rod 32 to rotate and reset, and the ejector rod 32 drives the ejector screw 1 34 and the ejector needle 33 to move in the direction away from the guide tube 2 13.

[0042] like Figure 6 to Figure 7 As shown, the material dividing component 2 4 is used to push the workpieces on the two material discharge seats 2 14 so that they are aligned with the corresponding tapping components 6.

[0043] The dividing cam 41 is rotatably set on the frame 1 and is connected to the rotating output end 8. It should be noted that the rotating output end 8 is connected to the rotating shaft of the dividing cam 41 through multiple gear meshing, so that the rotating output end 8 can drive the dividing cam 41 to rotate, and the middle part of the dividing rocker arm 44 is rotatably connected to the frame 1, the transition shaft 42 is threadedly connected to the end of the dividing rocker arm 44, and the bearing 43 is installed on the transition shaft 42. The outer ring of the bearing 43 can abut against the outer side wall of the dividing cam 41, that is, as the dividing cam 41 rotates, the outer side wall of the dividing cam 41 contacts the outer ring of the bearing 43, and then the thrust is transmitted to the dividing rocker arm 44 through the transition shaft 42, so that the dividing rocker arm 44 rotates.

[0044] The dividing fork 48 is installed at the end of the dividing rocker arm 44, the connecting ring 47 is installed on the dividing fork 48 and is arranged on the outer wall of the dividing double-headed screw 45, the dividing double-headed screw 45 is connected to the movable shaft 410, the two supports 411 are respectively installed on the corresponding discharge seats 14, the movable shaft 410 is slidably arranged on the two supports 411, the two dividing push plates 412 are both connected to the movable shaft 410, the reset spring 49 is sleeved on the outer wall of the dividing double-headed screw 45, and the connecting ring 47 can cooperate with one of the supports 411 to squeeze the reset spring 49.

[0045] It should be noted that, as the material dividing cam 41 rotates, the material dividing rocker 44 rotates, and the material dividing rocker 44 drives the material dividing double-headed screw 45 and the movable shaft 410 to move through the material dividing fork 48 and the connecting ring 47. At the same time, the connecting ring 47 cooperates with one of the supports 411 to squeeze the return spring 49, and the movable shaft 410 drives the two material dividing push plates 412 to move on the corresponding material discharge seat 14, and the material dividing push plates 412 push the workpiece toward the material discharge seat 14. The material trough 141 on the side, as the material dividing cam 41 continues to rotate, the thrust applied to the material dividing rocker rod 44 disappears, and the elastic force generated by the reset spring 49 acts on the connecting ring 47, and the connecting ring 47 drives the material dividing double-headed screw 45 and the movable shaft 410 to move, and the movable shaft 410 drives the two material dividing push plates 412 to move on the corresponding material discharge seat 14 respectively, and the material dividing push plates 412 push the workpiece to the material trough 141 on the other side of the material discharge seat 14.

[0046] The clamping member 5 is used to clamp the workpiece on the discharge seat 2 14. Specifically, the clamping member 5 includes a clamping rod 51, a clamping plate 52, a clamping cam 53, a transition shaft 3 54, a bearing 3 55 and a reset spring 56.

A positioning groove 57 adapted to the workpiece is provided on the clamping plate 52. A reset spring 56 connects the clamping rod 51 and the frame 1.

[0047] The elastic force of the reset spring 56 causes the clamping rod 51 to reset, and the clamping rod 51 drives the clamping plate 52 to rotate, so that the end of the clamping plate 52 is close to the discharge seat 2 14, until the workpiece is clamped on the discharge seat 2 14, and the workpiece is located in the positioning groove 57, so as to ensure the stability of the workpiece during the processing. As the clamping cam 53 continues to rotate, when the notch on the clamping cam 53 is aligned with the end of the clamping rod 51, the clamping cam 53 is out of contact with the clamping rod 51, so the thrust acting on the clamping rod 51 disappears, and the elastic force of the reset spring 56 causes the clamping rod 51 to reset, and the clamping rod 51 drives the clamping plate 52 to rotate, so that the end of the clamping plate 52 is away from the workpiece on the discharge seat 2 14.

[0048] The pushing member 7 is used to push the corresponding tapping member 6 close to the workpiece on the discharge seat 14. The pushing member 7 includes a feed cam 71, a push rod 72, a push rod 73, a transition shaft 74 and a bearing 75. The feed cam 71 is rotatably set on the frame 1 and is transmission-connected to the rotary output end 8. The rotary output end 8 is transmission-connected to the rotating shaft of the feed cam 71 through a plurality of gear meshings, so that the rotary output end 8 can drive the feed cam 71 to rotate.

[0049] That is, as the feed cam 71 rotates, the protruding portion of the feed cam 71 contacts the outer ring of the bearing four 75, and then transmits the thrust to the push rod 72 through the transition shaft four 74, so that the push rod 72 rotates, and the push rod 72 drives the push rod 73 to approach the tapping piece 6 and exert pressure on it, thereby pushing the tapping piece 6 to approach and contact the workpiece on the discharge seat two 14.

[0050] The tapping piece 6 can tap and reset the workpiece on the discharge seat 14. Specifically, the tapping piece 6 includes a gear set 61, a transmission shaft 62, a reset spring 63 and a tapping head 64. The gear set 61 is transmission-connected to the rotating output end 8, the transmission shaft 62 is movably arranged on the frame 1, and the transmission shaft 62 is transmission-connected to the gear set 61. The tapping head 64 is coaxially mounted on the transmission shaft 62, and the tapping head is aligned with the workpiece on the discharge seat 14. The reset spring 63 is sleeved on the outer wall of the transmission shaft 62. The end of the transmission shaft 62 has a positioning portion 621. A ball bearing 12 is arranged between the transmission shaft 62 and the frame 1. When the transmission shaft 62 slides to make the tapping head 64 close to the workpiece on the discharge seat 14, the positioning portion 621 can cooperate with the ball bearing 12 to squeeze the reset spring 63.

[0051] A transmission eccentric disk 9 is rotatably provided on the frame 1, and the transmission eccentric disk 9 is transmission-connected with the rotating output end 8. Specifically, the rotating output end 8 is transmission-connected with the transmission eccentric disk 9 through a plurality of gear meshings, so that the rotating output end 8 can drive the transmission eccentric disk 9 to rotate. Two racks 10 are movably provided on the frame 1, one end of the connecting shaft 11 is rotationally connected with the eccentric portion of the transmission eccentric disk 9, and the other end of the connecting shaft 11 is rotationally connected with the rack 10. The single rack 10 is transmission-connected with the two gear sets 61. It should be noted that the rack 10 is meshed with one of the gears of the gear set 61, and the plurality of gears of the gear set 61 are The wheels realize transmission through meshing and coaxial arrangement. As the transmission eccentric disk 9 rotates, the transmission eccentric disk 9 drives the rack 10 to slide through the connecting shaft 11, and the rack 10 rotates the tapping head 64 through the gear set 61. It should be noted that in this embodiment, a single rack 10 is simultaneously connected to the two gear sets 61 for transmission, so the transmission shafts 62 and the tapping heads corresponding to the two gear sets 61 can be rotated at the same time to realize the tapping of two workpieces. Therefore, the two racks 10 cooperate with the corresponding gear sets 61 to realize the rotation of the four tapping heads 64 at the same time, so as to realize the simultaneous tapping of four workpieces.

[0052] A plurality of unloading parts 15 are arranged on the frame, and the unloading parts 15 include an unloading cam 151, an unloading swing rod 152, an unloading push pin 155, a second ejection screw 154, a second ejection screw sleeve 155, a second limit nut 156 and a fifth reset spring 157. The unloading cam 151 is rotatably arranged on the frame and is transmission-connected with the rotary output end. The rotary output end is transmission-connected with the rotating shaft of the unloading cam 151 through a plurality of gear meshing, so that the rotary output end 8 can drive the unloading cam 151 to rotate. The middle part of the unloading swing rod 152 is rotationally arranged on the frame, the second ejection screw 154 is arranged at the end of the unloading swing rod 152, and the unloading push pin 155 is rotationally arranged on the frame. The needle 155 is arranged on the ejection screw 154, the ejection screw sleeve 155 is inserted on the discharge seat 2, the limit nut 156 is threadedly connected to the ejection screw sleeve 155, and the reset spring 157 is arranged between the limit nut 156 and the ejection screw 154. The reset spring 157 is connected to the limit nut 156 and is sleeved on the ejection screw sleeve 155. The limit nut 156 and the ejection screw 154 can cooperate to squeeze the reset spring 157. The rotation of the unloading cam 151 can push the unloading rocker 152 to rotate, so that the unloading push needle 155 passes through the ejection screw sleeve 155 to push the workpiece away from the discharge seat 14.

[0053] It should be noted that after the workpiece is tapped, the protruding part of the unloading cam 151 contacts the end of the unloading rocker 152, thereby pushing the unloading rocker 152 to rotate, and the unloading rocker 152 drives the ejector screw 2 154 and the unloading push pin 155 to move in the direction close to the unloading seat 2. At this time, the ejector screw 2 154 cooperates with the limiting nut 2 156 to squeeze the reset spring 5 157, and the unloading push pin 155 passes through the ejector screw sleeve 2 155 to push the workpiece away from the unloading seat 2, thereby realizing automatic unloading of the workpiece.

[0054] As the unloading cam 151 continues to rotate, the protruding part of the unloading cam 151 loses contact with the unloading rocker 152, and the thrust applied to the unloading rocker 152 disappears. At this time, the elastic restoring force of the reset spring 5 157 pushes the unloading rocker 152 to rotate and reset, and the unloading rocker 152 drives the ejection screw 2 154 and the unloading push pin 155 to move in the direction away from the discharge seat 2 14.

[0055] The working principle of the present invention is as follows:

[0056] First, the workpiece produced by the cold heading machine continuously enters the material trough 121 of the material discharging seat 12 through the material guide pipe 11;

[0057] As the rotary output end 8 on the cold heading machine rotates, the dividing cam 21 rotates under the driving action of the rotary output end 8, and the outer wall of the dividing cam 21 contacts the outer ring of the bearing 212. The dividing cam 21 transmits the thrust to the dividing rocker arm 22 through the transition shaft 211. The dividing rocker arm 22 rotates and drives the dividing spring rod 25, the support seat 28 and the guide rod 27 to move through the dividing pull rod 23 and the connecting ring 24. At the same time, the support seat 28 cooperates with the support seat 29 to squeeze the reset spring 26, and the guide rod 27 drives the dividing push plate 210 along The material trough 121 moves, and the material distribution push plate 210 pushes the workpiece to one side of the material trough 121 to align it with one of the material guide tubes 13. As the material distribution cam 21 continues to rotate, the thrust applied to the material distribution rocker 22 disappears, and the elastic force generated by the reset spring 26 acts on the support seat 28. The support seat 28 drives the guide rod 27 and the material distribution spring rod 25 to move, and the guide rod 27 drives the material distribution push plate 210 to move along the material trough 121. The material distribution push plate 210 pushes the workpiece to the other side of the material trough 121 to align it with the other material guide tube 13.

[0058] At the same time, the ejection cam 31 is also rotated under the driving action of the rotating output end 8, and the protruding portion of the ejection cam 31 contacts the lower end of the ejection rod 32, applying a thrust to the ejection rod 32, thereby pushing the ejection rod 32 to rotate, and the ejection rod 32 drives the ejection screw 1 34 and the ejection needle 33 to move in the direction close to the material guide tube 2 13, and the ejection needle 33 pushes the workpiece to move, and the workpiece pushes the adjacent workpiece to move in turn, so that one workpiece is separated from the material guide tube 2 13 and reaches the material discharge seat 2 14. At the same time, the ejection screw 1 34 also cooperates with the limit nut 1 36 to squeeze the return spring 2 37, and the return spring 2 37 is in a compressed state. As the ejection cam 31 continues to rotate, the protruding portion of the ejection cam 31 is out of contact with the ejection rod 32, and the thrust applied to the ejection rod 32 disappears. At this time, the elastic restoring force of the return spring 2 37 pushes the ejection rod 32 to rotate and reset, and the ejection rod 32 drives the ejection screw 1 34 and the ejection needle 33 to move in the direction away from the material guide tube 2 13;

[0059] At the same time, the material distribution cam 41 also rotates under the power of the rotating output end 8. As the material distribution cam 41 rotates, the material distribution swing rod 44 rotates. The material distribution swing rod 44 drives the material distribution double-headed screw 45 and the movable shaft 410 to move through the material distribution fork 48 and the connecting ring 47. At the same time, the connecting ring 47 cooperates with the support 411 to squeeze the reset spring 49, and the movable shaft 410 drives the two material distribution push plates 412 to move on the corresponding material discharge seat 14 respectively. The material distribution push plates 412 push the workpiece As the material distribution cam 41 continues to rotate, the thrust applied to the material distribution rocker 44 disappears, and the elastic force generated by the reset spring 49 acts on the connecting ring 47. The connecting ring 47 drives the material distribution double-headed screw 45 and the movable shaft 410 to move. The movable shaft 410 drives the two material distribution push plates 412 to move on the corresponding material distribution seat 14, and the material distribution push plates 412 push the workpiece to the material distribution trough 141 on the other side of the material distribution seat 14.

[0060] Similarly, the clamping cam 53 also rotates under the power of the rotating output end 8, and the outer wall of the clamping cam 53 contacts the outer ring of the bearing three 55, and the thrust is transmitted to the clamping rod 51 through the transition shaft three 54. The clamping rod 51 moves to deform the reset spring 56, and at the same time, the clamping rod 51 drives the clamping plate 52 to rotate, so that the end of the clamping plate 52 is close to the discharge seat two 14 until the workpiece is pressed on the discharge seat two 14;

[0061] At the same time, the transmission eccentric disk 9 rotates under the driving action of the rotating output end 8, and the transmission eccentric disk 9 drives the rack 10 to slide through the connecting shaft 11. The rack 10 rotates the corresponding transmission shaft 62 and the tapping head through the two gear sets 61. At the same time, the feed cam 71 rotates under the power of the rotating output end 8. The protruding part of the feed cam 71 contacts the outer ring of the bearing four 75, and the thrust is transmitted to the push rod 72 through the transition shaft four 74. The push rod 72 rotates and drives the push rod 73 to approach the transmission The shaft 62 exerts pressure on it, pushing the transmission shaft 62 and the tapping head 64 close to and contacting the workpiece on the unloading seat 14, and the tapping head 64 performs tapping processing on the workpiece. At the same time, the transmission shaft 62 drives the positioning part to cooperate with the ball bearing 12 to squeeze the return spring 4 63. As the feed cam 71 continues to rotate, the protruding part of the feed cam 71 is out of contact with the outer ring of the bearing 4 75. The elastic restoring force of the return spring 4 63 acts on the positioning part 621, so that the transmission shaft 62 moves and drives the tapping head 64 away from the workpiece.

[0062] After the tapping process is completed, as the clamping cam 53 rotates, the notch 531 on the clamping cam 53 is aligned with the end of the clamping rod 51. At this time, the thrust of the clamping cam 53 on the clamping rod 51 disappears, and the elastic force of the reset spring 56 resets the clamping rod 51. The clamping rod 51 drives the clamping plate 52 to rotate, so that the end of the clamping plate 52 is away from the workpiece on the discharge seat 14.

[0063] At the same time, the unloading cam 151 rotates under the driving action of the rotating output end 8, and the protruding part of the unloading cam 151 contacts the end of the unloading rocker 152, pushing the unloading rocker 152 to rotate so that it drives the ejection screw 2 154 and the unloading push pin 155 to move in the direction close to the unloading seat 2 14, and the ejection screw 2 154 cooperates with the limit nut 2 156 to squeeze the reset spring 5 157, and the unloading push pin 155 passes through the ejection screw sleeve 2 155 to push the processed workpiece away from the unloading seat 2. Then, as the unloading cam 151 continues to rotate, the protruding part of the unloading cam 151 disengages from the unloading rocker 152, and the thrust applied to the unloading rocker 152 disappears. The elastic restoring force of the reset spring 5 157 pushes the unloading rocker 152 to rotate and reset, and the unloading rocker 152 drives the ejection screw 2 154 and the unloading push pin 155 to move in the direction away from the unloading seat 2 14.
