[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The present invention provides the following technical solution: a hexagonal nut tapping device, comprising two supports 1, a tapping table 3 is arranged above the two supports 1, a pusher assembly and a clamping assembly are sequentially mounted on the tapping table 3 from the side closest to the feed side, a chip removal assembly and a discharge assembly are sequentially mounted below the two supports 1 from top to bottom, a tapping assembly is mounted at the top of the two supports 1, and a controller 2 is fixedly connected to the side wall of one support 1 away from the other support 1.

[0018] See appendix Figure 1-5 Before the device taps the hexagonal nut, the feeding robotic arm places the hexagonal nut with the machined round hole into the pushing position of the pushing component. The pushing component starts to push the hexagonal nut with the machined round hole to the tapping position. The clamping component starts to clamp the hexagonal nut with the machined round hole, waiting for tapping. When the device taps a hexagonal nut, it starts by tapping the round hole of the hexagonal nut that has been machined through the tapping assembly; The debris generated during the tapping of hexagonal nuts is conveyed and collected by the chip removal assembly. After the device taps the hexagonal nut, the clamping assembly starts to reset. At this time, the feeding robot arm places the newly machined hexagonal nut with a round hole in the pushing position of the pushing assembly. The pushing assembly continues to push the newly machined hexagonal nut with a round hole to the tapping position. During this process, the newly machined hexagonal nut pushes the tapped hexagonal nut to the discharge assembly. The discharge assembly starts to transport and collect the tapped hexagonal nut. The above steps are repeated for the newly machined hexagonal nut with a round hole until all hexagonal nuts are tapped.

[0019] Specifically, the pusher assembly includes a support 101 fixed to the top of the tapping table 3 near the feed side, a first electric cylinder 102 fixed to the support 101 near the feed side, and a pusher claw 103 fixed to the output end of the first electric cylinder 102 extending through the support 101 to the other side.

[0020] See appendix Figure 4 The feeding assembly is started by the first electric cylinder 102, which drives the output end to extend, thereby extending the feeding claw 103 to complete the feeding of the hexagonal nut with the round hole.

[0021] Specifically, the clamping assembly includes two clamping claws 201 symmetrically arranged at the top of the tapping table 3 at the material processing position, and a moving drive assembly is assembled between the two clamping claws 201 and the tapping table 3 and the two supports 1.

[0022] See appendix Figure 4 The clamping assembly holds the hexagonal nut with a round hole machined by two clamping claws 201 that are close to each other, thus completing the clamping of the hexagonal nut with a round hole machined.

[0023] Specifically, the moving drive assembly includes a mounting bracket 301 fixed between two supports 1, two first mounting plates 305 symmetrically fixed to the two supports 1 away from each other's sidewalls, two movable seats 312 fixed to the bottom ends of two clamping jaws 201, and two movable slots 309 symmetrically opened on the tapping table 3. The mounting bracket 301 is located at the bottom end of the two supports 1 and is rotated 90 degrees from L. A first motor 308 is fixedly connected to the short end of the mounting bracket 301 near the long end sidewall, and two motors 308 are symmetrically rotatably connected to the short end away from the long end sidewall. Rotary shafts 302 are provided, one end of which is connected to the output end of the first motor 308 via a coupling, and the other end of which is connected to the inner wall of the mounting bracket 301 via a bearing. Gears 303 and first pulleys 304 are fixedly fitted onto the two rotating shafts 302 from the side closest to to the side furthest from the mounting bracket 301, respectively. Two first mounting plates 305 are located above the mounting bracket 301, and rotating shafts 302 are rotatably connected to the two first mounting plates 305, with the rotating shafts 302 connected to the first mounting plates 305 via bearings. The two rotating shafts 302 are rotatably connected. Each end of one shaft passes through an adjacent first mounting plate 305 and extends to both sides, where a second pulley 306 and an incomplete gear 310 are respectively fixed. The second pulley 306 is closer to the first pulley 304, and the incomplete gear 310 is farther from the first pulley 304. A friction-driven first transmission belt 307 is sleeved between the adjacent first pulley 304 and the second pulley 306. Two movable slots 309 are located at the positions of two movable seats 312, and the bottom ends of the two movable seats 312 pass through the two movable seats 312. The groove 309 extends to the bottom of the tapping table 3 and is slidably connected to the fixed rod 311. The movable seat 312 is slidably connected to the fixed rod 311 through the opening sleeve. The two fixed rods 311 are fixed to the adjacent bracket 1 away from each other's end walls. The two fixed rods 311 are respectively sleeved with connecting springs 313. The two ends of the connecting springs 313 are respectively connected to the movable seat 312 and the bracket 1 close to each other's side walls. The bottom ends of the two movable seats 312 are respectively fixed with racks 314. The two racks 314 are meshed with two incomplete gears 310.

[0024] See appendix Figure 2-5The moving drive assembly is started by the first motor 308, which drives the output end to rotate, causing the connected rotating shaft 302 to rotate. The connected rotating shaft 302 drives the connected gear 303 and the first pulley 304 to rotate. The connected gear 303 drives the meshing gear 303 to rotate, which in turn drives the connected rotating shaft 302 to rotate. The connected rotating shaft 302 drives the connected first pulley 304 to rotate. The two first pulleys 304 drive the two second pulleys 306 to rotate through the two friction-driven first transmission belts 307. The second pulley 306 drives the two rotating shafts 302 to rotate, and the two rotating shafts 302 drive the two incomplete gears 310 to rotate. During the initial rotation of the two incomplete gears 310, the two racks 314 are driven to move towards each other. The two racks 314 drive the two moving seats 312 to stretch the two connecting springs 313 on the two fixed rods 311 and move towards each other. The two moving seats 312 drive the two clamping claws 201 to move towards each other, clamping the hexagonal nut with the round hole machined, thus completing the clamping of the hexagonal nut with the round hole machined. As the two incomplete gears 310 continue to rotate, their teeth disengage from the two racks 314. Under the reset force of the two connecting springs 313, the two movable seats 312 move away from each other on the two fixed rods 311. The two movable seats 312 drive the two clamping claws 201 to move away from each other and reset. The process is repeated, involving repeated clamping of materials to tap the hexagonal nuts that have round holes.

The two first mounting plates 305 and the two fixing rods 311 are fixed to the adjacent second mounting plates 401 near their end walls. Two first conveying rollers 404 are symmetrically rotatably connected between the second mounting plates 401. One first conveying roller 404 extends through the adjacent second mounting plate 401 to the other side and is connected to the through side by a bearing. The other end is rotatably connected to the adjacent second mounting plate 401 by a bearing. The other first conveying roller 404 is rotatably connected to the adjacent second mounting plate 401 by bearings at both ends. The two first conveying rollers 404 are fitted with a friction-driven first conveyor belt 405. The debris collection box 406 is located on the discharge side of the first conveyor belt 405.

[0026] See appendix Figure 2 and 4The chip removal component drops the chips generated during the tapping process onto the rotating first conveyor belt 405 through the chip drop port 403, and the rotating first conveyor belt 405 transports them into the chip collection box 406 to complete the chip removal. The rotation of the first conveyor belt 405 is driven by two first conveyor rollers 404 rotating in the same direction.

[0027] Specifically, the discharge assembly includes a second motor 501 fixed to the side wall of a second mounting plate 401 away from the other second mounting plate 401, two second conveying rollers 502 symmetrically rotatably connected between the two second mounting plates 401, and a nut collection box 504 disposed at the top of the mounting frame 301. One end of one second conveying roller 502 is connected to the output end of the second motor 501 via a coupling, and the other end is connected to the adjacent second mounting plate 401 via a bearing. One end of the other second conveying roller 502 extends through the adjacent second mounting plate 401 to the other side and is connected to the through side via a bearing, and the other end is rotatably connected to the adjacent second mounting plate 401 via a bearing. The two second conveying rollers 502 are located below the two first conveying rollers 404 and the distance between them is sufficient to allow the passage of tapped hexagonal nuts. The two second conveying rollers 502 are fitted with a friction-driven second conveyor belt 503. The feed length of the second conveyor belt 503 is longer than that of the first conveyor belt 405, and the nut collection box 504 is located on the discharge side of the second conveyor belt 503.

[0028] See appendix Figure 2 and 4 The discharge assembly completes the discharge by conveying the tapped hexagonal nuts to the nut collection box 504 via the rotating second conveyor belt 503; The rotation of the second conveyor belt 503 is started by the second motor 501, which drives the output end to rotate, thereby driving the connected second conveyor roller 502 to rotate. The connected second conveyor roller 502 drives the friction-driven second conveyor belt 503 to rotate, and the second conveyor belt 503 drives another second conveyor roller 502 to rotate. The two second conveyor rollers 502 rotating in the same direction drive the second conveyor belt 503 to rotate.

[0029] Specifically, adjacent first conveying rollers 404 and second conveying rollers 502 extend through adjacent second mounting plates 401 to the other side and are respectively fixedly sleeved with third pulleys 601. The two third pulleys 601 are sleeved with second transmission belts 602 connected by friction transmission.

[0030] See appendix Figure 5The rotation of the two first conveying rollers 404 drives the connected third pulley 601 to rotate through the rotating second conveying roller 502. The connected third pulley 601 drives the friction-driven second transmission belt 602 to rotate. The second transmission belt 602 drives another third pulley 601 to rotate. The other third pulley 601 drives the connected first conveying roller 404 to rotate. The connected first conveying roller 404 drives the other first conveying roller 404 to rotate through the friction-driven first conveyor belt 405.

[0031] Specifically, the tapping assembly includes a connecting frame 701 fixed to the top of two brackets 1. A second electric cylinder 702 is fixed to the top of the connecting frame 701. The output end of the second electric cylinder 702 extends through the connecting frame 701 and is fixed to a follower seat 703 below. A third motor 704 is fixed to the top of the follower seat 703.

[0032] See appendix Figure 4 The tapping assembly is started by the second electric cylinder 702 and the third motor 704. The second electric cylinder 702 drives the output end to extend, which in turn drives the follower seat 703 to extend. The follower seat 703 drives the third motor 704 and the tap 705 to extend. The third motor 704 drives the tap 705 to rotate. The extended and rotating tap 705 taps the round hole of the hexagonal nut that has been machined.
