[0026] 1. A feeding mechanism, a tapping mechanism and a feeding mechanism are provided. The feeding mechanism transports the wire nuts to be processed along the tapping groove to the bottom of the tapping mechanism.

The cam 71 is coaxially fixedly connected to the outer periphery of the rotating shaft 73, and a plurality of cams 71 are provided, and the plurality of cams 71 are evenly distributed along the axial direction of the rotating shaft 73. In this embodiment, four cams 71 are provided, and one cam 71 is provided for two adjacent support rod 53 assemblies. The end of the rotating shaft 73 away from the base 12 penetrates the wall of the liquid storage chamber 51 and then extends out of the storage box 5.

[0055] The tapping mechanism 3 also includes a cooling assembly 37. The cooling assembly 37 includes a nozzle 372 and a water pump 371. The nozzle 372 is fixedly connected to the protective cover 13, and the outlet of the nozzle 372 faces the processing position of the tap 34. The water pump 371 is located on the side of the storage box 5 close to the main body 231, and the water pump 371 is used to transport the liquid in the liquid storage chamber 51 to the nozzle 372. The liquid inlet of the water pump 371 is connected to the liquid storage chamber 51 through a pipeline, and the liquid outlet of the water pump 371 is connected to the inlet of the nozzle 372 through a pipeline. The vibration mechanism 7 also includes a transmission assembly 72, which is connected between the water pump 371 and the rotating shaft 73, and the transmission assembly 72 includes a driving pulley 721, a driven pulley 722 and a belt body 723. The driving pulley 721 is coaxially fixedly connected to the output shaft of the water pump 371 , the driven pulley 722 is coaxially fixedly connected to the end of the rotating shaft 73 away from the base 12 , and the belt body 723 is sleeved on the outer circumference of the driving pulley 721 and the driven pulley 722 .

[0056] The implementation principle of the tapping device for the wiring nuts of a circuit breaker in the embodiment of the present application is as follows: the vibration plate 23 pushes the wiring nuts into the feed slot 113 in sequence, and the wiring nuts enter the groove 241. The second driving cylinder 25 works to push the feeding member 24 to slide, so that the groove 241 is directly opposite to the tapping slot 111. The first driving cylinder 22 works to push the pushing member 21 to slide, and push the wiring nut in the groove 241 into the tapping slot 111, so that the wiring nut abuts the second chamfer 3611. When the inner hole of the wiring nut is directly opposite to the tap 34, the pressing block 361 abuts against the upper surface of the wiring nut. The fourth driving cylinder 32 works to drive the sliding seat 33 to move downward, and the sliding seat 33 abuts against the upper end of the second reset member 362, so that the pressing block 361 presses against the upper surface of the wiring nut. The sliding seat 33 moves downward to drive the rotating column 38 to move downward, and drives the tap 34 to move downward. The driving motor 39 works to drive the rotating column 38 to rotate, and drives the tap 34 to rotate to tap the wiring of the wiring nut. The abutment block 35 moves downward to abut the upper end of the stopper 44, pushing the stopper 44 to overcome the elastic force of the first reset member 45 and move downward, so that the stopper 44 is flush with the bottom of the discharge trough 114. The third drive cylinder 42 works to push the material discharge member 41 to slide, push the wire nut on the side of the tapping groove 111 away from the pusher 21 into the discharge trough 114, and then push it into the receiving hopper 43 from the discharge trough 114. The workpiece slides along the receiving hopper 43 to the filter screen 6. The water pump 371 pumps the liquid in the lower liquid chamber to the nozzle 372, and then the nozzle 372 sprays it to the processing position of the tap 34 to cool the tap 34 and the wire nut. The motor output shaft in the water pump 371 rotates, driving the active pulley 721 to rotate, driving the driven pulley 722 to rotate through the belt body 723, driving the rotating shaft 73 to rotate, driving the cam 71 to rotate, and the cam 71 rotates to abut the lower surface of the filter screen 6, so that the filter screen 6 vibrates vertically back and forth.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
