Abstract

PURPOSE: A manufacturing method of an insulator strut and a structure thereof are provided to cut down the manufacturing costs of an insulator strut and to reduce the manpower and working time therefor by inserting a stopper plate of the insulator strut into a bearing case and then compressing the bearing case with a strong force. CONSTITUTION: A bearing case(2) is manufactured from a steel pipe by cutting and pressing the lower part of the steel pipe to enlarge the diameter of the lower part. A fitting hole is formed in the center of another steel pipe for a stopper plate(1) to accept the upper end of the bearing case. Then, the steel pipe is pressed to have the bent structure of a circumferential end and the dual bent structure for the stopper plate. The bearing case is assembled to the stopper plate by an annular recessed portion(4) of the bearing case. The upper margin of the stopper plate is inserted into the annular recessed portion of the bearing case of an insulator strut(3) by a press. Therefore, the stopper plate is combined with the bearing case integrally.

본 발명은 인슐레이트 스트러트(Insulator-strut)의 제작방법 및 그 구조에 관한 것으로서, 더욱 상세하게는 자동차의 쇽압소바(Shock-absorber) 상측에 장착하여 방진을 하는 스토퍼 플레이트 (Stopper-plate)와 베어링 케이스(Bearing-case)의 접합부분을 압착하여 결합한 인슐레이트 스트러트(Insulator-strut)의 제작방법 및 그 구조에 관한 것이다.The present invention relates to a method for manufacturing an insulator strut and a structure thereof, and more particularly, a stopper plate and a bearing which are mounted on an upper side of a shock-absorber of a vehicle to be dustproof. The present invention relates to a method for manufacturing an insulation strut (Insulator-strut) in which a joint of a bearing-case is pressed and bonded to a structure thereof.

현재 자동차 공업이 나날이 발전하고 있으며 그에 맞추어 자동차 부품 개발에 끊임 없는 연구와 자금을 투입하여 새로운 자동차 개발에 노력하고 있다.Currently, the automobile industry is developing day by day, and accordingly, we are endeavoring to develop new automobiles by continuously investing research and funding in automobile parts development.

종래의 자동차 쇽압쇼바(Shock-absorber)에 장착되는 방진 스토퍼 프레이트와 베어링 케이스의 접합시에 두 분분을 용접하여 결합하였다.The two parts were welded and joined at the time of joining the bearing case and the dustproof stopper plate mounted on a conventional automobile shock-absorber.

그러나, 이러한 종래의 결합방법은 용접부가 재질 변형을 초래하여 수명이 단축되고 약화시키는 문제점이 있었다.However, such a conventional coupling method has a problem in that the weld portion causes material deformation to shorten and weaken the service life.

또한, 로스(loss)가 발생이 되고 작업 인력과 시간 및 비용이 증가하는 문제점이 있었다.In addition, there is a problem that a loss (loss) is generated and work manpower and time and cost increase.

따라서, 본 발명은 상기 종래의 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 인슐레이트-스트러트(Insulator-strut)의 구성부품인 스토퍼 플레이트(Stopper-plate)를 베어링 케이스(Bearing-case)에 끼운 후 강한 힘으로 베어링 케이스(Bearing-case)를 압축하여 환요입부를 요설함과 동시에 일체화시키므로써 작업시간과 인력을 절감하여 제품의 단가를 줄일 수 있는 인슐레이트 스트러트 (Insulator-strut)의 제작방법 및 그 구조를 제공하는 데 있다.Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to attach a stopper plate, which is a component of an insulator-strut, to a bearing-case. After inserting the bearing case by compressing the bearing case with a strong force, the method of manufacturing the insulator-strut can reduce the product cost by reducing the working time and manpower by consolidating and integrating the indentation part. And the structure thereof.

이와 같은 목적을 달성하기 위한 본 발명의 인슐레이트 스트러트(Insulator-strut)는 스토퍼 플레이트(Stopper-plate)와 베어링 케이스(Bearing-case)로 구성된 인슐레이트-스트러트(Insulator-strut)의 베어링 케이스에 요설된 환요입부에 의해서 스토퍼 플레이트가 일체화로 성형하여 달성하였다.The insulator strut of the present invention for achieving the above object is summarized in the bearing case of the insulator strut composed of a stopper plate and a bearing case. The stopper plate was integrally molded by the annular indentation.
