Description

Technical Field

[0001] The utility model relates to the technical field of carbon brush lead positioning, in particular to a carbon brush lead positioning device. Background Art

[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.

[0003] Currently, the carbon brush assembly and manufacturing in the carbon brush manufacturing industry mainly relies on the labor of cheap older workers. This assembly method requires manual positioning of the carbon body leads when welding them. However, the manual positioning method is inefficient and has poor accuracy, which easily leads to defective products. Therefore, a carbon brush lead positioning device is proposed. Summary of the Invention

[0004] The utility model provides a carbon brush lead positioning device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The carbon brush lead positioning device comprises a cylinder, a guide hole is opened on the surface of the cylinder, a guide rod is inserted into the guide hole, and a mounting plate is fixedly connected to one end of the guide rod away from the guide hole.

[0007] A further improvement of the technical solution of the present utility model is that: the bottom of the mounting plate is fixedly connected to the output end of the cylinder, and a positioning piece is overlapped on the top of the mounting plate.

[0008] A further improvement of the technical solution of the present invention is that a fixing nail is provided on the top of the positioning member, and the lower end of the fixing nail passes through the mounting plate.

[0009] A further improvement of the technical solution of the present invention is that: a V-shaped hole is opened at one end of the positioning piece, a carbon lead is overlapped on the inner wall of the V-shaped hole, and a carbon body is provided at one end of the carbon lead.

[0010] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0011] The utility model provides a carbon brush lead positioning device. By installing the device on a carbon brush spot welding assembly machine, the position of the carbon brush lead can be accurately fixed, so that the carbon brush can be quickly positioned during welding assembly or spring assembly in the production of automated equipment. When the external clamp transports the carbon body to the bottom of the positioning part, the cylinder is quickly pressed down to quickly position the lead to the middle position along the oblique angle of the V-shaped hole, so that other external welding structures can be quickly positioned. The setting of the V-shaped hole can position carbon body leads of different diameters, and it has stronger adaptability. Compared with conventional manual positioning, it can save a lot of labor costs and has higher positioning accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In this embodiment, during the welding and assembly process of the carbon brush production, the carbon body 8 is pushed by an external component to move the carbon body lead 9 to the bottom of the positioning member 5. Then, under the action of the cylinder 1, the mounting plate 4 is pulled downward, thereby driving the positioning member 5 to move downward. Under the action of the inclined surface of the inner wall of the V-shaped hole 7, the carbon body lead 9 is quickly moved to the middle position of the V-shaped hole 7, thereby completing the rapid positioning work. At the same time, during the positioning process, the mounting plate 4 can drive the guide rod 3 to slide along the guide hole 2, which can reduce the force at the connection point between the output end of the cylinder 1 and the mounting plate 4 during positioning, avoiding breakage at the connection during long-term use, making it more convenient to use.
