Combined commutator and production processing technology thereof

Abstract

The combined commutator comprises a hook-shaped commutator and a cushion block, wherein the hook-shaped commutator comprises a middle shaft sleeve and a plurality of hook-shaped commutator segments evenly arranged on the outer side of the middle shaft sleeve, the cushion block is in a disc shape, an inner hole allowing the middle shaft sleeve to be inserted therein is formed in the center of the cushion block, and the hook-shaped commutator segments are arranged in the inner hole; a circle of boss is arranged on the upper side of the cushion block, a plurality of clamping grooves are formed inthe boss, and hook foot parts of the hook-shaped commutator segments are embedded into the corresponding clamping grooves. The combined commutator is advantaged in that the combined mounting structure is adopted, so processing difficulty is reduced, and the product quality and performance are improved.

Description

technical field [0001] The invention relates to the field of commutators, in particular to a combined commutator and its production and processing technology. Background technique [0002] The commutator (English: commutator), commonly known as the commutator, is a DC permanent magnet series motor A component that is used to keep the motor running. Most of the current commutators are hook-shaped commutators, which are mainly formed by hook-shaped commutator pieces and bakelite powder, and then partially processed after molding, but for some special hook-shaped commutators, such as hook Commutators with relatively long legs will be more difficult to form in one piece, which will easily cause the hook feet to stick to bakelite powder, and spot welding will easily cause adverse risks during motor assembly, and it is also difficult to process the lower groove. If the slot cannot be milled through, the performance of the motor will be affected, and the overall processing is dif...

Problems solved by technology

Most of the current commutators are hook-shaped commutators, which are mainly formed by hook-shaped commutator pieces and bakelite powder, and then partially processed after molding, but for some special hook-shaped commutators, such as hook Commutators with relatively long legs will be more difficult to form in one piece, which will easily cause the hook feet to stick to bakelite powder, and spot welding will easily cause adverse risks during motor assembly, and it is also difficult to process the lower groove. If the slot cannot be milled through, it will affect the performance of the motor, and the overall processing is difficult, so a new processing technology is needed
