본 발명은 일정한 형상으로 재단되어 모서리 가공이 끝난 차량용 거울의 표면을 매끄럽게 가공하기 위한 장치에 관한 것으로서, 좀 더 구체적으로 표현하면 공기의 흡착력을 이용하여 거울을 압착판에 고정시킨후에 회전되는 원형의 가공판 위에 밀착케 함으로서 매끄러운 표면처리를 완성하는 것으로 표면가공에 따른 빠른 작업속도를 유지하며 불량 발생률을 최소화 함이 가능한 것이다.The present invention relates to a device for smoothly cutting the surface of a vehicle mirror is finished in a certain shape and the edge is finished, more specifically, the circular shape of the circular rotating after fixing the mirror to the pressing plate using the adsorption force of air It is possible to minimize the incidence of defects by maintaining a fast working speed according to the surface processing by completing a smooth surface treatment by making the surface close to the processing plate.
또한, 본 발명은 거울의 착탈이 매우 간편하여 여기에 수반되는 제반공정이 전혀 불필요한 것이기도 하다.In addition, the present invention is also very easy to attach and detach the mirror is not necessary at all the accompanying process.
이른바, 차랴이라면 필수적으로 실내의 후사경이나 차량 외부의 좌,우측 거울의 장착이 기본적으로 구비되어야 하는바 특히, 안전한 차량의 운행을 위하여 표면에 홈이 없는 매끈한 상태를 유지하여야 되었다.So-called, if you need to be equipped with a rearview mirror in the interior or the left and right mirrors of the outside of the vehicle should be basically provided, in particular, in order to safely drive the vehicle had to maintain a smooth state without grooves on the surface.
주지하다시피 차량용 거울은 앞,뒤차와의 차간거리조정 및 장애물확인 그리고 좌,우측방향을 운전자가 항시 확인하여 주행함이 요망됨으로 거울표면에 홈이나 요철이 있을시에는 맹 큰 사고의 위험이 있었던 것이다. 따라서, 거울표면의 가공은 거울생산의 공정상 매우 중요하였다.As it is well known, the mirror for the vehicle has been in danger of serious accidents when there are grooves or irregularities on the mirror surface because it is required that the driver always checks the distance between the front and rear cars, checks the obstacles and checks the left and right directions at all times. . Therefore, the processing of the mirror surface was very important in the mirror production process.
일반적으로 사용되는 차량용 거울의 표면가공장치 구조는 원형의 테이퍼부 안쪽 가공판이 회전을 함에 따라 양쪽 지지간에 의해 고정된 상판위로 4개의 실린더가 고정설치되고 각각의 실린더 하면으로 원형압착간이 부착되는데 이 원형 압착간의 하면으로 차량용 거울이 삽입되게 3개의 홈이 삭설된 원형판이 있고 이 원형판에 거울을 끼워 원형압착간에 삽지케하고서 실린더로 하여금 이 원형압착간을 회전하는 가공판에 밀착케 함으로서 표면의 가공처리가 이루어지는 것으로 종래의 이러한 구성이 갖는 제반결점은 매우 산적하였다.In general, the surface processing device structure of a mirror for a vehicle is used. As the inner surface of the circular tapered part rotates, four cylinders are fixedly installed on the upper plate fixed by both supports, and a circular compression zone is attached to the lower surface of each cylinder. There is a circular plate with three grooves cut into the lower surface of the pressing rod to insert the vehicle mirror, and the surface is processed by inserting the mirror into the circular plate and inserting the mirror between the pressing lines and allowing the cylinder to adhere to the rotating plate. All the drawbacks of such a conventional configuration are very large.
즉, 4개의 원형압착간이 서로 회전되면서 움직여서 자칫 서로 부딪치는 경우가 빈번하게 발생하였다. 따라서, 거울의 파손율이 매우 높았고 파손된 유리조각으로 인해 가공판의 표면이 찢어져 부득이 가공판의 전체적 교체를 가져와 많은 재산상의 손실을 가져왔었다. 또한, 구조자체가 갖는 복잡성으로 고장발생율의 심화와 그 수리에 많은 시간과 노력을 필요로 하였던 것이다.That is, the four circular compression rods are frequently rotated while bumping against each other. Therefore, the failure rate of the mirror was very high and the broken pieces of glass caused the surface of the plate to be torn, which inevitably resulted in a total replacement of the plate, resulting in a great loss of property. In addition, the complexity of the structure itself required a lot of time and effort to deepen the failure rate and repair.
이와함께, 종래의 표면처리기계는 1개의 원형압착간에 이상이 발생하여 회전가공판 등에 유리조각등이 끼이게 되면 전체 가공거울의 불량품이 발생하여 즉, 12개의 거울에 하자가 발생되이 불량품 양산의 온상이 되었다. 그러나 무엇보다도 가장 큰 문제점은 거울을 원형판에 삽지하는데 있었다.In addition, in the conventional surface treatment machine, if an abnormality occurs between one circular crimp and glass chips etc. are caught in the rotating processing plate, defective products of the entire processing mirror are generated, that is, defects are generated in 12 mirrors. It became. But most of all, the biggest problem was in inserting the mirror into the circular plate.
즉, 거울의 후면부위에 테이프를 접착하고서 원형판에 고정시켰던바, 가공후에 이를 제거하는데도 번거로울 뿐더러 테이프의 자국이 매우 흉하게 남아 이를 제거코자 고온의 열로 녹여 제거해야 하는등 공정의 추가와 수공비등 그 불편함은 말할 수 없이 컸었다. 따라서, 이러한 테이프를 쓰지 않고서도 그 불량율을 최소화 하게한 것에의 요망이 있었다. 따라서 본 출원인은 92년 실용신안출원 제1617호로 "차랑용 거울의 표면가공장치"를 제시한 바 있다.In other words, the tape was attached to the rear part of the mirror and fixed to the round plate, which is not only cumbersome to remove after processing, but also the mark of the tape remains very ugly, so it must be removed by melting it with high temperature to remove it. Was indescribably great. Therefore, there was a desire to minimize the failure rate without using such a tape. Accordingly, the present applicant has proposed the "surface processing apparatus of the mirror for a car" as Utility Model Application No. 1617 in 1992.
선출원된 구조는 가공되려는 거울이 2개씩 표면가공되는 것으로 테이프를 대신하여 공기흡착기를 이용 거울에 붙이고 제거하는데 있어 그 편리함을 도모케 하였고 테이프자국제거의 추가공정을 제거하였으며 종래의 4개 압착간의 유동되던 것에 비하여 2개로 그 수를 줄여 서로 부딪히는 율을 최소화 하였고 설혹 파손품이 생겨도 기존의 12개 파손에 비하여 단 2개만이 불량처리 됨으로서 원상회복능력이 빠르게 한 것이며, 또한, 거울을 좌, 우로 유동시킬 수 있어 그 효용성을 높인 것이다. 그러나 이러한 선출원은 원형가공판의 회전에만 의지하여 흡착된 거울이 회전되었고 실린더의 피스톤부가 그대로 공기흡착부를 겸하여 압착판에 과다한 무리가 따랐다.The pre-applied structure has two mirrors to be processed, and it is convenient to attach and remove the mirrors by using an air absorber instead of tape. Compared to the previous one, the number was reduced to two to minimize the rate of collision with each other. Even if damages occurred, only two defects were treated poorly compared to the existing 12 damages. We can improve the utility. However, such a prior application was rotated by the adsorbed mirror only by the rotation of the circular processing plate, and the piston part of the cylinder was acting as an air adsorption part, followed by an excessive crowd on the compression plate.
또한 단 2개만의 거울가공이 이루어져 주문량이 많을 경우에는 이에 적절히 대처할 수 없는 문제가 발생되었다.In addition, only two mirrors are made, so when a large quantity of orders arises a problem that cannot be properly handled.
따라서, 본 발명은 이와같은 제반문제점을 해결하고자 별도의 소형 구동모우터를 설치하여 이 구동모우터를 설치하여 이 구동모우터와 압착판상의 피스톤에 부드럽게 끼워진 기어와 체인으로 연결되어 원형가공판의 회전과 동시에 소형구동모우터가 구동되어 압착판을 회저시켜 그 표면가공 정도를 높인 것이며, 압착판을 압압시켜주는 실린더의 피스톤의 하단부축봉에 원형볼을 삽설하여 압착판과의 사이에 설치하고 흡착부는 실린디에서 별도로 관을 인출하여 압착판에 복수로 설치되게한 차량용 거울의 표면가공장치를 제공코자 한 것이다.Therefore, in order to solve the above problems, the present invention installs a separate small drive motor and installs the drive motor, which is connected to the drive motor and the piston smoothly fitted to the piston on the pressing plate, thereby rotating the circular plate. At the same time, the small driving motor is driven to improve the surface finish by rotating the presser plate.The circular ball is inserted into the lower end rod of the piston of the cylinder that presses the presser plate, and is installed between the presser plate and adsorption. The department intends to provide a factory value for the surface of the vehicle mirror which allows the pipes to be separately drawn from the cylinder and installed on the pressing plate.
