Description

Technical Field

[0001] The utility model relates to the field of carbon brush processing, in particular to a wire plugging mechanism for carbon brush processing. Background Art

[0002] Carbon brushes are common electrical contact devices, commonly used in electric motors, generators, and other rotating equipment. Made of a conductive material, typically carbon or carbide, they possess a certain degree of hardness and conductivity. They contact the rotating motor rotor or slip rings, transferring current from the stationary part to the rotating part, thereby ensuring the proper operation of the motor or generator.

[0003] The carbon brush itself is made of graphite and a part of metal. Copper wire needs to be pulled out separately to connect the circuit to the equipment. During production, holes are mainly punched on the surface of the carbon brush, and then one end of the wire is manually placed in the hole, and copper powder is poured in. The copper powder is then knocked to compact it, thereby fixing the wire. However, the manual operation method is time-consuming and labor-intensive. At the same time, the amount of copper powder poured manually is different, and the knocking force is difficult to be uniform, which will lead to inconsistent quality of the connection. The copper wire is prone to falling off during later use. Utility Model Content

The weight sensor 21 is used to weigh the copper powder on the weighing frame 22. After the weight reaches the standard, the driving motor 15 is reversed, driving the movable plate 20 to rotate downward. After the weighing frame 22 tilts, the copper powder is poured out, and at the same time the stopper 13 moves forward and fits with the wear-resistant gasket 36 to block the falling of the copper powder.

[0031] See Figure 1-Figure 7 As shown, the automatic wire cutting device includes an upper plate 28 arranged on the inner side of the support frame 3, and an array of driving wheels 29 are rotatably installed between the workbench 1 and the upper plate 28.

After the copper powder flows down from the weighing frame 22, it can automatically flow into the discharge funnel 11. When the clamping cylinder 6 contracts and the clamping rod 7 is lifted, the limit block 10 moves upward to the top of the movable frame 8, so that the bottom of the clamping rod 7 is separated from the lower outlet of the discharge funnel 11, so that the copper powder can flow out. When the clamping cylinder 6 is extended, it drives the clamping rod 7 to be pressed down, and the discharge funnel 11 reaches the top of the carbon brush below, and automatically stops moving, and the clamping rod 7 enters the hole of the carbon brush and continues to press down. At this time, the limit block 10 moves downward in the movable frame 8, and the limit ring 9 makes it convenient for the staff to observe the depth of the downward pressure during the installation and debugging process, thereby adjusting the parameters of the clamping cylinder 6.
