Description

모터용 다이캐스팅 하우징 구조 {Die Casting Housing Structure for Motor}Die Casting Housing Structure for Motor

본 고안은 모터에 사용되도록 사출성형되는 다이캐스팅(die-casting) 하우징에 관한 것으로서, 특히 정밀 치수 관리가 필요로 하는 다이캐스팅 하우징의 고정자 압입부와 베어링부를 무가공 상태에서 프레스금형으로 강제 압입하여 필요로 하는 치수를 정밀하게 얻을수 있도록 하는 모터용 다이캐스팅 하우징 구조에 관한 것이다.The present invention relates to a die-casting housing that is injection molded for use in a motor, and in particular, a stator indentation and a bearing part of a die-casting housing requiring precise dimensional management are forced by press molding into a press mold in a non-processed state. The present invention relates to a die-casting housing structure for a motor that enables precisely obtaining dimensions.

주지된 바와같이, 종래의 모터용 다이캐스팅 하우징은 일차적으로 다이캐스팅 하우징을 사출하고, 그 사출물을 CNC나 범용 선반을 이용하여 정밀치수가 필요로 하는 부분(예: 베이링부, 고정자 압입부)을 가공하여 목표 치수를 제공하였다.As is well known, conventional die-casting housings for motors primarily inject a die-casting housing, and process the injection-molded parts (e.g., bearing and stator presses) using CNC or general-purpose lathes. Target dimensions were provided.

즉, 종래에는 도 1에서와 같이 다이캐스팅 하우징(1)을 사출하고, 도 2에서와 같이 상기 사출된 다이캐스팅 하우징(1)으로 고정자와 베어링이 삽입될수 있도록 고정자압입부(2)와 베어링부(3)를 별도로 구비되는 CNC나 범용 선반을 이용하여 가공하도록 하였다.That is, in the related art, the die casting housing 1 is injected as shown in FIG. 1, and the stator press-fitting part 2 and the bearing part 3 can be inserted into the injected die casting housing 1 as shown in FIG. 2. ) Was processed using a CNC or universal lathe provided separately.

그러나, 상기에서와 같이 별도의 CNC나 범용 선반을 이용하여 다이캐스팅 하우징(1)에서 정밀 치수가 필요로 하는 고정자압입부(2)와 베어링부(3)를 가공하는 경우 그 가공공정에 따른 작업시간이 많이 소요될뿐만 아니라, 고정자압입부(2)와 베어링부(3)의 가공시 진원도, 동심도, 직각도 등의 관리규격을 만족하는 정밀가공에 상당한 어려움이 따랐다.However, as described above, when machining the stator press-fitting part 2 and the bearing part 3 that require precise dimensions in the die-casting housing 1 by using a separate CNC or general-purpose lathe, the working time according to the machining process Not only is this required, but there are considerable difficulties in the precision processing that satisfies the management standards such as roundness, concentricity and squareness when the stator press-fit part 2 and the bearing part 3 are machined.

더불어, 다이캐스팅 하우징을 사출하기 위한 금형의 제작공정 또한 고정자압입부(2)와 베어링부(3)의 후(後)가공 고정을 염두에 둬야 하므로, 다이캐스팅 하우징의 사출을 위한 금형의 제작에도 불필요하게 많은 시간을 소요시켜야 하는 불편함이 있었으며, 이로인하여 제품의 생산단가는 물론 그 제작 어려움이 상당하였다.In addition, since the manufacturing process of the mold for injecting the die casting housing must also be taken into consideration of the post-processing fixing of the stator indentation portion 2 and the bearing portion 3, it is unnecessary to manufacture the mold for injection of the die casting housing. There was an inconvenience of having to spend a lot of time, and due to this, the production cost of the product as well as the difficulty of its production was considerable.

따라서, 상기와 같은 종래의 문제점을 해결하기 위한 본 고안은, 정밀한 치수관리가 필요로 하는 다이캐스팅 하우징의 내측에 치수제어용 수단을 성형한 후 이를 프레스금형으로 강제 압입하므로서, 종래에서와 같이 별도의 도구(예: CNC, 범용선반)를 사용하여 가공하지 않고도 다이캐스팅 하우징의 가공부위에서 진원도, 동심도, 직각도 등의 관리규격을 만족하는 치수를 정밀하게 얻을수 있도록 하고, 더불어 가공공정에 따른 작업시간의 소요시간을 대폭 줄이면서 제품에 대한 생산원가를 절감시키고자 하려는데 그 목적이 있는 것이다.Therefore, the present invention for solving the conventional problems as described above, by forming a dimensional control means on the inner side of the die-casting housing that requires precise dimensional management, and then forcibly presses it into a press mold, a separate tool as in the prior art (E.g. CNC, general purpose lathes), it is possible to precisely obtain dimensions satisfying the management standards such as roundness, concentricity, and squareness at the machining part of the die-casting housing without machining using a CNC, general purpose lathe. The aim is to reduce production costs for products while significantly reducing time.

상기 목적 달성을 위한 본 발명 모터용 다이캐스팅 하우징 구조는, 고정자압입부와 베어링부의 목표치수가 함께 제공되는 모터용 다이캐스팅 하우징을 사출 성형하되,The die-cast housing structure of the present invention for achieving the above object, injection molding the motor die-casting housing provided with the target dimensions of the stator indentation and the bearing portion,

상기 다이캐스팅 하우징의 내측에는 고정자압입부와 베어링부의 목표치수를 제어하는 치수제어용 수단을 형성함을 특징으로 하고,And dimension control means for controlling a target dimension of the stator press-fit part and the bearing part inside the die-casting housing.

상기 치수제어용 수단은 프레스금형의 강제압입으로 에지부의 이탈이 이루어지는 리브로 구성함을 특징으로 한다.The dimension control means is characterized by consisting of a rib that is separated from the edge portion by a forced press of the press die.

즉, 본 고안은 사출금형으로 다이캐스팅 하우징에서 고정자압입부와 베어링부의 목표치수를 함께 제공한 후 그 제어가 치수제어용 수단에 의해 이루어지도록 하므로서, 제품에 대한 생산성은 물론 초기 조건의 설계로 직각도, 동심도, 진원도 등의 관리규격을 일시에 만족시키는데 그 특징이 있는 것이다.In other words, the present invention is to provide the target dimensions of the stator indentation and the bearing portion in the die-casting housing as an injection mold, so that the control is made by the means for dimensional control, so that the productivity of the product as well as the design of the initial conditions at right angles, It is characterized by satisfying management standards such as concentricity and roundness.

이하, 첨부된 도면에 의거하여 본 고안의 바람직한 일실시예를 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention based on the accompanying drawings.

도 3은 본 고안의 일실시예로 모터용 다이캐스팅 하우징 구조의 평면도이고, 도 4는 본 고안의 일실시예로 모터용 다이캐스팅 하우징 구조의 측단면도 이다.3 is a plan view of a die casting housing structure for a motor as an embodiment of the present invention, Figure 4 is a side cross-sectional view of the die casting housing structure for a motor as an embodiment of the present invention.

도 3 및 도 4에 도시된 바와같이, 모터용 다이캐스팅 하우징(11)을 사출 성형하되, 상기 다이캐스팅 하우징(11)의 사출성형시 고정자압입부(12)와 베어링부(13)의 목표치수를 함께 제공하고, 더불어 상기 다이캐스팅 하우징(11)의 내측에는 리브(10)를 함께 사출 성형한다.As shown in FIGS. 3 and 4, the injection molding of the die casting housing 11 for the motor is performed, and the target dimensions of the stator press-fitting part 12 and the bearing part 13 are used together during the injection molding of the die casting housing 11. In addition, the rib 10 is injection molded together inside the die casting housing 11.

이후, 상기 리브(10)가 형성된 다이캐스팅 하우징(11)의 내측으로 프레스금형(도시하지 않음)을 화살표방향(P)으로 강제 압입하면, 상기 프레스금형의 강제압입에 따라 리브(10)의 에지부(a) 탈락이 이루어지면서 고정자압입부(12)와 베어링부(13)의 목표치수가 제어된다.Subsequently, when the press die (not shown) is press-fitted in the direction of the arrow P into the die-casting housing 11 in which the rib 10 is formed, the edge portion of the rib 10 is forced in accordance with the press-pressing of the press mold. (a) As the dropping is performed, the target dimensions of the stator indentation part 12 and the bearing part 13 are controlled.

즉, 본 고안은 종래에서와 같이 별도의 도구(예: CNC, 범용선반)를 사용하여 가공하지 않고 프레스금형을 다이캐스팅 하우징(11)의 내측면에 강제 압입하면, 상기 다이캐스팅 하우징(11)의 내측에 형성된 리브(10)의 에지부(a)가 탈락하면서 그 내부의 고정자압입부(12)와 베어링부(13)는 진원도, 동심도, 직가도 등의 관리규격을 만족하는 치수로 만들어지고, 이에따라 모터용 다이캐스팅 하우징(11)의 내부로는 고정자와 베어링의 삽입이 용이하게 이루어질수 있게 되는 것이다.That is, the present invention, if the press mold is pressed into the inner surface of the die-casting housing 11 without using a separate tool (for example, CNC, universal lathe) as in the prior art, the inside of the die-casting housing 11 As the edge portion (a) of the rib 10 formed in the dropout falls inside, the stator indentation portion 12 and the bearing portion 13 are made to have dimensions satisfying management standards such as roundness, concentricity, straightness, and the like. The stator and the bearing may be easily inserted into the die casting housing 11 for the motor.

이상에서 설명한 바와같이 본 고안은 고정자압입부와 베어링부의 치수관리 규격을 프레스금형의 강제압입시 리브의 에지부 이탈로 제어되도록 하므로서, 무가공으로 다이캐스팅 하우징의 가공부위에서 진원도, 동심도, 직각도 등의 관리규격을 만족하는 치수를 정밀하게 제공하고, 더불어 가공공정에 따른 작업시간의 소요시간을 대폭 줄이면서 제품에 대한 생산성은 물론 그 생산원가를 절감하는 효과를 제공한다.As described above, the present invention is to control the dimensions of the stator indentation and the bearing part by the deviation of the edge of the rib during forced press of the press mold, so that the roundness, concentricity, right angle, etc. It precisely provides the dimensions that meet the management standard, and also greatly reduces the time required for the processing process, and reduces the productivity of the product as well as the production cost.
