[0002] Carbon brushes are essential components used in electrical equipment such as motors and generators, performing various functions, including conductivity, commutation, and protection. Conduction: During operation, carbon brushes maintain close contact with the rotating commutator or slip rings, transferring current from the power source to the rotor windings, or vice versa. Carbon brushes offer excellent electrical conductivity, ensuring stable current transmission. Commutation: In DC motors, carbon brushes also perform commutation. As the motor rotor rotates, the carbon brushes contact different segments of the commutator, redirecting the current and ensuring that the current in the rotor windings remains in one direction, generating continuous torque. Protection: Carbon brushes lubricate the commutator or slip ring surfaces, reducing wear. Due to their relatively low hardness, carbon brushes wear first when in contact with the commutator or slip rings, minimizing wear on the commutator or slip rings. Furthermore, carbon brushes offer excellent electrical conductivity. Sintering with different material ratios yields varying electrical signal characteristics, ensuring the safe operation of the motor or generator.

Specific embodiments

[0022] The present utility model will be further described in detail below in conjunction with embodiments: Embodiment

[0023] As Figure 1-6 shown, the present utility model provides a carbon brush assembly fixture device, including a base 1, a fixing bracket 2 is fixedly connected to the top of the base 1, an ejector rod 3 is inserted into the interior of the fixing bracket 2, a first spring 4 is arranged at one end of the ejector rod 3, the other end of the first spring 4 is fixedly connected to the surface of the fixing bracket 2, one end of the ejector rod 3 is fixedly connected to a sliding plate 5, a first slider 6 is fixedly connected to the bottom of the sliding plate 5, a first slide rail 7 is slidably connected to the interior of the first slider 6, the bottom of the first slide rail 7 is fixedly connected to the top of the base 1, a first bracket bearing 8 is fixedly connected to the top of the sliding plate 5, and a first brush shell clamping block 9 is fixedly connected to the top of the sliding plate 5.

[0024] In this embodiment, an external component is used to pull the second bracket bearing 16 upward. While stretching the second spring 17, the second slider 13 slides along the second slide rail 12, driving the spring clip 15 to move upward. Subsequently, an external component is used to pull the first bracket bearing 8 to move, causing the first slider 6 to slide along the first slide rail 7, and one end of the ejector rod 3 compresses the first spring 4. Furthermore, the sliding plate 5 drives the first brush shell clamp 9 to move, expanding the distance between the first brush shell clamp 9 and the second brush shell clamp 10. Subsequently, after the external component transports the brush shell between the first brush shell clamp 9 and the second brush shell clamp 10, the external component stops applying force to the first bracket bearing 8. Under the action of the elastic force of the first spring 4, the ejector rod 3 pulls the sliding plate 5 to reset, clamping the brush shell 11. Embodiment

[0025] As Figure 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the top of the base 1 is fixedly connected with the second brush shell clamp 10. One side of the first brush shell clamp 9 is lapped with the brush shell 11. One side of the second brush shell clamp 10 is fixedly connected with the second slide rail 12. The surface of the second slide rail 12 is slidably connected with the second slider 13. One side of the second slider 13 is fixedly connected with the sliding bracket 14. One side of the sliding bracket 14 is fixedly connected with a spring clip 15 with a notch opened at the lower end. The top of the sliding bracket 14 is fixedly connected with the second bracket bearing 16. One side of the sliding bracket 14 is sleeved with the second spring 17. The lower end of the second spring 17 is sleeved with one side of the base 1.

[0026] In this embodiment, when assembling the spring, through the transportation of an external component, while inserting the spring into the brush shell, an upward pulling force is applied to the second bracket bearing 16, enabling the spring to push the carbon body forward. After the spring is completely inserted into the brush shell 11, the pulling force on the second bracket bearing 16 is released, causing the spring clip 15 to move downward and reset, preventing the spring from falling off. Subsequently, through the notch opened at the lower end of the spring clip 15, the brush shell 11 and the carbon body lead are welded together by an external welding component to complete the assembly. Embodiment

[0027] As Figure 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the inner wall of the fixed bracket 2 is fixedly connected with a third slide rail 18 with through holes opened on its surface. The inner wall of the third slide rail 18 is slidably connected with the third slider 19. The surfaces of the two third sliders 19 are fixedly connected with the carbon body clamps 20. The tops of the two third sliders 19 are sleeved with the third spring 21. The inner wall of the fixed bracket 2 is fixedly connected with a cylinder 22. The output end of the cylinder 22 is fixedly connected with a triangular top block 23. One end of the triangular top block 23 passes through the through hole opened on the surface of the third slide rail 18 and laps with the third slider 19.

[0028] In this embodiment, the carbon body is inserted into the cavity in the brush housing 11 through an external component. Subsequently, after releasing the pulling force on the second bracket bearing 16, under the pulling force of the second spring 17, the spring clip 15 moves downward to clamp the carbon body. When assembling the spring, through the conveyance of the external component, while inserting the spring into the brush housing, an upward pulling force is applied to the second bracket bearing 16, enabling the spring to push the carbon body forward. Under the action of the air cylinder 22, the triangular top block 23 pushes the two third sliders 19 to slide along the third slide rail 18 to both sides and stretches the third spring 21. When the carbon body is pushed by the spring between the two carbon body clamping blocks 20, the air cylinder 22 retracts, and through the pulling of the third spring 21, the carbon body clamping blocks 20 clamp and fix the carbon body.

[0029] Next, the working principle of this carbon brush assembly fixture device will be specifically described.

[0030] As Figure 1-6 shown, when assembling the carbon brush, the second bracket bearing 16 is pulled upward through an external component. While stretching the second spring 17, the second slider 13 slides along the second slide rail 12, driving the spring clip 15 to move upward. Subsequently, the first bracket bearing 8 is pulled to move through the external component, causing the first slider 6 to slide along the first slide rail 7 and one end of the ejector rod 3 to compress the first spring 4. Further, the sliding plate 5 drives the first brush housing clamping block 9 to move, expanding the distance between the first brush housing clamping block 9 and the second brush housing clamping block 10. Subsequently, after the brush housing is conveyed between the first brush housing clamping block 9 and the second brush housing clamping block 10 through the external component, the external component stops applying force to the first bracket bearing 8. Under the elastic force of the first spring 4, the ejector rod 3 pulls the sliding plate 5 to reset, clamping the brush housing 11. Subsequently, the carbon body is inserted into the cavity in the brush housing 11 through an external component. After releasing the pulling force on the second bracket bearing 16, under the pulling force of the second spring 17, the spring clip 15 moves downward to clamp the carbon body. When assembling the spring, through the conveyance of the external component, while inserting the spring into the brush housing, an upward pulling force is applied to the second bracket bearing 16, enabling the spring to push the carbon body forward. Under the action of the air cylinder 22, the triangular top block 23 pushes the two third sliders 19 to slide along the third slide rail 18 to both sides and stretches the third spring 21. When the carbon body is pushed by the spring between the two carbon body clamping blocks 20, the air cylinder 22 retracts, and through the pulling of the third spring 21, the carbon body clamping blocks 20 clamp and fix the carbon body. After the spring is completely inserted into the brush housing 11, the pulling force on the second bracket bearing 16 is released, causing the spring clip 15 to move downward and reset to prevent the spring from falling off. Subsequently, through the notch opened at the lower end of the spring clip 15, the brush housing 11 and the carbon body lead wire are welded together through an external welding component to complete the assembly.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
