我厂为满足冶金矿山、城市交通需要而生产的各类直流电机,其关键部件换向器的套筒压圈一向是质量要求高、数量多、周期要求短、备件要求足的重点工件。长期来,工件加工手段没变,质量要求却不断提高。特别是工件的锥度加工,其锥度(3°和30°锥度)同换向器绝缘圈的配合要求很高,图1所示为电车电机换向器套筒。
I plant to meet the needs of metallurgical and mining, urban transport needs of the production of various types of DC motor, the key components of the commutator sleeve pressure has always been the high quality requirements, the number of large, short cycle requirements, spare parts required for the full focus of the workpiece. For a long time, the means of processing of workpieces have not changed, but the quality requirements have been continuously improved. In particular, the workpiece taper machining, the taper (3 ° and 30 ° taper) with the commutator insulating ring with high requirements, Figure 1 shows the tram motor commutator sleeve.
