[0036] The nut assembly machine of the present invention includes a frame 100, a gearbox seat transportation device 200, an assembly station 300 for assembling nuts and gearbox seats, a rotary transfer component 400 for transferring the gearbox seat from the gearbox seat transportation device 200 to the assembly station 300, a gearbox seat steering component 500 for steering the gearbox seat transferred to the assembly station 300 by the rotary transfer component 400, a main runner 600, a nut transportation device 610 for transferring nuts to the main runner 600, at least one sub-runner 620, a nut splitting component 700 for transferring the nuts in the main runner 600 to the sub-runner 620, and a nut assembly component 800 for assembling the nuts in the sub-runner 620 onto the gearbox seat and applying oil to the connection between the nut and the gearbox seat;

[0037] The gearbox seat transportation device 200 is arranged on the frame 100, the assembly station 300 is arranged on the frame 100, the rotary transfer component 400 is arranged between the gearbox seat transportation device 200 and the assembly station 300, the gearbox seat steering component 500 is arranged on one side of the rotary transfer component 400, the main runner 600 is fixedly arranged on the frame 100, the nut transportation device 610 transfers nuts to the main runner 600, and the nut splitting component 700 is arranged between the main runner 600 and the sub-runner 620.

[0038] Among them, the frame 100 mainly plays a supporting role for each structure of the nut assembling machine; the gearbox seat transporting device 200 is mainly used for transporting the gearbox seat, and the nut transporting device 610 is mainly used for transporting nuts. The nut transporting device 610 may include a transporting drive motor and a transporting conveyor belt. The output end of the transporting drive motor drives the transporting conveyor belt to rotate, thereby completing the transportation of the nuts.

[0039] Specifically, when the nut assembling machine of the present invention needs to assemble nuts onto the gearbox seat, first, the rotary material transfer assembly 400 transfers the gearbox seat placed on the gearbox seat transporting device 200 into the assembling station 300. At this time, the gearbox seat turning assembly 500 turns the gearbox seat in the assembling station 300 from a horizontal placement to a vertical placement, so as to facilitate the assembly of the nuts into the gearbox seat. At this time, the nut transporting device 610 transfers the nuts into the main flow channel 600. Under the action of the nut splitting assembly 700, the nuts are transferred from the main flow channel 600 into the splitting flow channel 620. Finally, the nut assembling assembly 800 first transfers the nuts in the splitting flow channel 620 onto the gearbox seat in the assembling station 300, and then the nut assembling assembly 800 rotates the nuts, so that the nuts are assembled onto the gearbox seat. At the same time, during the process of assembling the nuts onto the gearbox seat, the nut assembling assembly 800 performs an oiling action on the connection between the nuts and the gearbox seat.

[0040] More specifically, another set of assembling stations 300, another set of rotary material transfer assemblies 400, another set of gearbox seat turning assemblies 500, another set of splitting flow channels 620, another set of nut splitting assemblies 700, and another set of nut assembling assemblies 800 can also be provided on one side of the main flow channel 600, so as to further improve the working efficiency of assembling the nuts onto the gearbox seat, thereby facilitating the improvement of production capacity.

[0041] In this embodiment, the rotary material transfer assembly 400 includes a material transfer part 410, a transfer rotary cylinder 420 for driving the material transfer part 410 to rotate, a lifting cylinder 430 for pushing the material transfer part 410 to perform reciprocating motion in the vertical direction, a cylinder support 440, a plurality of transfer gripper cylinders 450 for gripping the gearbox seat, and a transfer support 460. The transfer support 460 is fixedly connected to the frame 100, the transfer rotary cylinder 420 is fixedly connected to the transfer support 460, the output end of the transfer rotary cylinder 420 is fixedly connected to the material transfer part 410, a plurality of transfer gripper cylinders 450 are fixedly connected to the end of the material transfer part 410, the cylinder support 440 is fixedly arranged on the support, and the lifting cylinder 430 is fixed on the cylinder support 440, and the output end of the lifting cylinder 430 faces the material transfer part 410.

[0042] Among them, when the rotary material transfer assembly 400 of the present invention needs to transfer the gearbox seat from the gearbox seat transfer device 200 to the assembly station 300, first, the lifting cylinder 430 enters the working state, so that the lifting cylinder 430 lifts the material transfer part 410 to a certain height to avoid the material transfer part 410 colliding with surrounding components during rotary material transfer. Secondly, the material transfer rotary cylinder 420 drives the material transfer part 410 to rotate 180 degrees, so that the material transfer jaw cylinder 450 transfers the gearbox seat from the gearbox seat transfer device 200 to the assembly station 300. Here, the material transfer jaw cylinder 450 can also transfer the assembled nut and gearbox seat back into the gearbox seat transfer device 200 driven by the material transfer part 410, thus forming a cyclic action of material feeding and finished product discharging, thereby significantly improving the working efficiency of the present invention.

[0043] Specifically, the cylinder bracket 440 mainly plays a supporting role for the lifting cylinder 430 to improve the stability of the lifting cylinder 430, and the material transfer bracket 460 mainly plays a supporting role for the material transfer rotary cylinder 420 to improve the stability of the material transfer rotary cylinder 420, thereby improving the overall working stability of the entire rotary material transfer assembly 400.

[0044] In this embodiment, the gearbox seat steering assembly 500 includes a steering track 510, a steering drive device 520, a steering jaw cylinder 530, and a longitudinal drive cylinder 540 for driving the steering drive device 520 to move reciprocally. The steering track 510 is fixedly connected to the frame 100, the steering drive device 520 is slidably connected to the steering track 510, the output end of the steering drive device 520 is fixedly connected to the steering jaw cylinder 530, the steering drive device 520 drives the steering jaw cylinder 530 to rotate, the steering jaw cylinder 530 drives the gearbox seat in the assembly station 300 to turn, and the output end of the longitudinal drive cylinder 540 is fixedly connected to the steering drive device 520.

[0045] Among them, when the gearbox seat is transferred from the rotary material transfer assembly 400 to the assembly station 300, the gearbox seat is in a horizontal placement state, and the horizontally placed gearbox seat is not conducive to the assembly of nuts. Therefore, the gearbox seat steering assembly 500 performs a steering operation on the gearbox seat. First, the longitudinal drive cylinder 540 drives the steering drive device 520 to slide on the steering slide rail, so that the steering drive device 520 drives the steering jaw cylinder 530 to approach the assembly station 300, and the steering jaw cylinder 530 clamps the horizontally placed gearbox seat. At this time, the steering drive device 520 drives the steering jaw cylinder 530 to rotate, so that the gearbox seat is vertically placed in the assembly station 300. At this time, the gearbox seat steering assembly 500 completes the steering action of the gearbox seat. The steering drive device 520 can be a motor, that is, the motor drives the steering jaw cylinder 530 to rotate.

[0046] In this embodiment, the nut shunting assembly 700 includes a shunting bracket 710, a longitudinal driving device 720, a shunting adapter 730, a transfer channel 740, a shunting support base 750, a shunting pusher 760, and a pusher driving cylinder 770. The shunting bracket 710 is fixedly connected to the frame 100. The longitudinal driving device 720 is fixedly connected to the shunting bracket 710. The shunting adapter 730 is fixedly connected to the output end of the longitudinal driving device 720. The transfer channel 740 is arranged on one side of the main channel 600. The lower end of the shunting adapter 730 abuts against the transfer channel 740. The shunting support base 750 is fixedly connected to the main channel 600. The shunting pusher 760 is slidably connected within the shunting support base 750. The pusher driving cylinder 770 is fixedly connected to the shunting support base 750. The pusher driving cylinder 770 drives the shunting pusher 760 to move. The nuts within the main channel 600 are pushed by the shunting pusher 760 through the feed hole 711 opened on the main channel 600 and enter the transfer channel 740.

[0047] Among them, the nut shunting assembly 700 is mainly used to shunt the nuts within the main channel 600 into the shunt channels 620. When the nut shunting assembly 700 needs to perform the nut shunting action, first, the pusher driving cylinder 770 enters the working state. Thus, the pusher driving cylinder 770 drives the shunting pusher 760 to reciprocate. Thus, the shunting pusher 760 pushes the nuts within the main channel 600 through the feed hole 711 into the transfer channel 740. At this time, the longitudinal driving device 720 drives the shunting adapter 730 to reciprocate within the transfer channel 740. Two material distribution holes are opened at one end of the shunting adapter 730 extending into the transfer channel 740. After the nuts enter the transfer channel 740, the longitudinal driving device 720 drives the shunting adapter 730 to move. Thus, the shunting adapter 730 transfers the nuts into the shunt channels 620 through the material distribution holes. The shunting adapter 730 reciprocates within the transfer channel 740. Thus, the nuts are shunted into different shunt channels 620 through the material distribution holes. Thus, the nut shunting assembly 700 completes the nut distribution action.

[0048] In this embodiment, the nut shunting assembly 700 further includes a material stop assembly 780 for blocking the movement of the nuts within the main channel 600. The material stop assembly 780 is arranged on the main channel 600. The material stop assembly 780 includes a stop cylinder 781, a cylinder base 782, and a bent stop member 783. The cylinder base 782 is fixedly arranged on the lower side of the main channel 600. The stop cylinder 781 is fixedly connected to the upper side of the cylinder base 782. The stop member 783 is slidably arranged within the main channel 600. The stop cylinder 781 drives the stop member 783 to reciprocate within the main channel 600 to press or release the nuts within the main channel 600.

[0049] Among them, before the nut shunting component 700 shunts the material flowing into the main flow path, the material stop component 780 first stops the material, so that the nuts in the main flow path 600 can be orderly shunted into the shunt flow path 620 by the nut shunting component 700.

[0050] Specifically, the cylinder base 782 plays a role in supporting the stop cylinder 781. The stop cylinder 781 enters the working state and drives the stop member 783 to move in the main flow path 600, so as to press the nut against the inner wall of the main flow path 600, thus completing the stop function of the nut in the main flow path 600.

[0051] It is worth noting that the stop cylinder 781 can drive the stop member 783 to move together with the output end of the stop cylinder 781 through any connecting piece.

[0052] In this embodiment, the nut shunting component 700 also includes an intermittent material stop component 790 for intermittently stopping the nuts in the main flow path 600. The intermittent material stop component 790 includes a nut stop portion 791 and an intermittent drive cylinder 792 for driving the nut stop portion 791 to stop the nuts in the main flow path 600. The intermittent drive cylinder 792 is fixedly connected to the shunt bracket 710. The nut stop portion 791 is arranged on the upper side of the main flow path 600, and the output end of the intermittent drive cylinder 792 is fixedly connected to the nut stop portion 791.

[0053] Among them, the nut shunting component 700 only shunts a part of the nuts in the main flow path 600. When the nuts not shunted in the main flow path 600 pass through the nut shunting component 700, the intermittent material stop component 790 intermittently stops the nuts, so as to control the transmission cycle of the nuts, and further enable each component to work orderly.

[0054] Specifically, the intermittent drive cylinder 792 drives the nut stop portion 791 to press the nuts in the main flow path 600, thus completing the stop function of the nuts in the main flow path 600. At the same time, the intermittent drive cylinder 792 works intermittently, so as to achieve the purpose of controlling the nut transmission cycle.

[0055] In this embodiment, the nut assembly component 800 includes an assembly longitudinal driving device 810, an assembly slide rail 820, an adjusting part 830, an adjusting slide rail 840, a longitudinal air cylinder 850, a transfer device 860, a vertical driving air cylinder 870, an oiling component 900, a plurality of nut driving motors 880 and a plurality of assembly jaw air cylinders 890. The assembly slide rail 820 is fixedly connected to the output end of the longitudinal driving device 720. The adjusting part 830 is fixedly connected to the assembly slide rail 820. The adjusting slide rail 840 is fixedly arranged on the adjusting part 830. The transfer device 860 is slidably connected to the adjusting slide rail 840. The longitudinal air cylinder 850 is fixedly connected to the adjusting part 830. The longitudinal air cylinder 850 drives the transfer device 860 to make longitudinal reciprocating motion on the adjusting slide rail 840. The vertical driving air cylinder 870 is fixedly connected to the transfer device 860. The oiling component 900 is arranged on the side wall of the transfer device 860. The nut driving motor 880 is fixedly connected to the oiling component 900. The output end of the nut driving motor 880 is fixedly connected to the assembly jaw air cylinder 890. The nut driving motor 880 drives the assembly jaw air cylinder 890 to rotate, and the assembly jaw air cylinder 890 rotatably mounts the nut onto the tooth box seat.

[0056] Among them, the nut assembly component 800 first performs a transfer action on the nuts in the sub-runner 620. First of all, the assembly longitudinal driving device 810 can be driven by the cooperation of a motor and a lead screw. Thus, the assembly longitudinal driving device 810 drives the assembly slide rail 820 to achieve lateral position adjustment. The assembly slide rail 820 drives the adjusting part 830 to move together. The adjusting slide rail 840 on the adjusting part 830 can achieve the longitudinal displacement of the transfer device 860, that is, the longitudinal air cylinder 850 drives the transfer device 860 to perform reciprocating adjustment in the longitudinal direction. The assembly longitudinal driving device 810 drives the transfer device 860 to perform reciprocating adjustment in the lateral direction. The vertical driving air cylinder 870 drives the transfer device 860 to perform reciprocating adjustment in the vertical direction, so that the assembly jaw air cylinder 890 can achieve position transformation in all directions.

[0057] Specifically, the assembly jaw air cylinder 890 first clamps the nuts in the sub-runner 620 and transfers them to the tooth box seat at the assembly station 300. At this time, the nut driving motor 880 enters the working state. Thus, the nut driving motor 880 drives the jaw air cylinder to rotate, so that the nuts are loaded into the tooth box seat. The oiling component 900 performs an oiling action on the connection between the nut and the tooth box seat, so that the nut assembly component 800 completes the transfer of the nuts, as well as the oiling action during the process of loading the nuts into the tooth box seat and loading the nuts into the tooth box seat.

[0058] In this embodiment, the oiling assembly 900 includes an oiling adapter 910, a first oiling joint 920, and a second oiling joint 930.
