Description

Technical Field

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

[0002] Carbon brushes, also known as electric brushes, are sliding contact components widely used in many electrical devices. Carbon brushes are primarily made of graphite, impregnated graphite, and metallic (copper and silver) graphite. Carbon brushes transfer energy or signals between the fixed and rotating parts of motors, generators, or other rotating machinery. They are typically made of pure carbon with a coagulant and are typically square in shape. They are attached to a metal bracket and secured to the shaft by a spring. As the motor rotates, electrical energy is transferred to the coils via the commutator. Because they are primarily composed of carbon, they are susceptible to wear and should be regularly maintained and replaced, and carbon deposits removed.

[0003] After searching, the utility model patent with patent number CN219444620U discloses "a motor carbon brush grinding device". This motor carbon brush grinding device makes the grinding structure (semi-circular arc plate) and the rotating roller into a detachable structure, and designs the grinding structure into two semi-circular arc plates to facilitate direct removal from the rotating roller; the inner arc surface is adapted to the diameter of the outer wall of the rotating roller to achieve the positioning of the semi-circular arc plate, and the first connecting block and the second connecting block are connected by fasteners, and the fasteners are detachable, which is convenient for subsequent replacement of the semi-circular arc plate; when the semi-circular arc plate is worn or needs to be replaced with a semi-circular arc plate of a different outer diameter, it is only necessary to disassemble and assemble the semi-circular arc plate without disassembling the entire rotating roller, which makes disassembly and assembly simpler and more efficient.

[0004] The semicircular plate of the device needs to be fixed by a second connecting block and screws. The second connecting block is an inward protrusion relative to the semicircular plate, and its production is relatively complicated. In addition, the installation of multiple sets of screws is relatively troublesome and very inconvenient to use.

[0005] Therefore, it is necessary to provide a motor carbon brush grinding device to solve the above technical problems. Utility Model Content
