Abstract

본 발명은 스테핑 모터용 로터의 제조방법에 대해 개시한다. 종래의 스테핑 모터용 로터는 그 구성부품이 마그네트, 회전축, 회전체, 피니언기어등으로 다수로 구성되어 있었기 때문에 제작이 번잡하고 조립효율이 매우낮아 생산성이 높지 않아 대량생산하기 어려운 문제가 있었으며, 정밀도가 높은 로터를 제작하기가 매우어렵고, 제작단가도 많이 소요되므로써 스테핑 모터의 단가가 상승되는 문제가 있었다. 본 발명에서는 로터를 상,하형을 구비하고, 하형에 피니언기어 성형용 요입성형부를 형성하고, 그 상측으로 마그네트가 안착되는 안착부와, 상형에 마그네트를 지지하는 지지부와, 상,하형 중심에 축관통구멍 성형용 코어를 형성하여, 회전심체 성형부를 형성하며, 상,하형 내부로 주물을 주입하도록 관통되는 주입구를 형성한다음, 상,하형을 결합하여 주입구를 통해 주물을 주입하여 금형성형의 방법과, 피니언기어 및 회전심체를 일체로 절삭가공한후 그 외측에 한쌍의 마그네트를 본딩처리하여 결합시키는 방법으로 제조하므로써 종래의 문제점을 해결하였다.The present invention discloses a method for manufacturing a rotor for a stepping motor. Conventional stepping motor rotor has a problem that it is difficult to mass-produce because its component parts are composed of a large number of magnets, rotating shafts, rotating bodies, pinion gears, etc. It is very difficult to manufacture a high rotor, and the manufacturing cost is also high, there is a problem that the unit cost of the stepping motor is increased. In the present invention, the rotor is provided with upper and lower molds, and the lower mold is formed with a concave molded part for pinion gear forming, and a seating portion on which the magnet is seated on the upper side, a support portion for supporting the magnet on the upper mold, and a center of the upper and lower molds. A core for forming a shaft through-hole is formed to form a rotating core molded part, and an injection hole penetrates to inject the casting into the upper and lower molds. Then, the upper and lower molds are combined to inject the casting through the injection hole to form the mold. The conventional problem has been solved by manufacturing the method and the pinion gear and the rotating core by integrally cutting and then bonding a pair of magnets to the outside to bond them together.
