Abstract

Provided is a method for manufacturing a spindle flange combined with a knuckle for a car, comprising: a first cutting step of cutting the outer circumferential surface of a cylindrical member, wherein the outer circumferential surface excluding a predetermined length from one side is cut so that a spindle is formed on the other side; a second cutting step of cutting the side excluded in the first cutting step, in all directions to form a flange of a predetermined shape; and a hole forming step of forming a through hole to correspond with a fixing hole of a knuckle meeting the flange. When the outer circumferential surface of the cylindrical member is cut, all outer circumferential surface except the predetermined length from the one side is cut to form the spindle on the other side, and the side of the cylindrical member, which was not cut, is cut in all directions to form the flange of the predetermined shape. Therefore, the method for manufacturing the spindle flange does not need post-machining and can reduce manufacturing processes since edges of the flange are formed round.

Description

자동차용 넉클에 결합되는 스핀들 플랜지 제작방법{Spindle flange manufacturing method that combines the knuckles for cars}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a spindle flange coupled to an automotive knuckle,

본 발명은 자동차용 넉클에 결합되는 스핀들 플랜지 제작방법에 관한 것이다.The present invention relates to a method of manufacturing a spindle flange coupled to an automotive knuckle.

종래 스핀들의 구조는 나사 체결홈들이 외곽부에 형성되는 사각형상의 플랜지 블록 중앙에 일정직경의 구멍이 형성되어, 다단의 단턱이 형성되고 일체형으로 단조 및 주물된 원기둥형 스핀들의 일단부가 넉클부 중앙홀에 맞춰지고, 넉클부 중앙홀 외곽의 관통홀들을 통과한 볼트가 스핀들 플랜지와 체결되어 진다The structure of the conventional spindle is such that a hole having a predetermined diameter is formed in the center of a square flange block in which the screw fastening grooves are formed in the outer periphery of the spindle, and one end of the forged and cast cylindrical spindle is integrally formed with the knock- And the bolts passing through the through holes in the outside of the knuckle center hole are fastened to the spindle flange

이때의 플랜지 블록은 일반적으로 사각형상으로 이루어진다. At this time, the flange block is generally formed into a rectangular shape.

그리고, 사각형상의 플랜지 블록은 모서리부가 라운드지게하고 넉클 접촉면은 정밀 후가공처리된다. In addition, the rectangular flange block rounds the corners and the knuckle contact surfaces are finely processed.

이러한, 후가공은 스핀들의 제조과정에 불편함이 있으며, 제조단가가 상승하는 문제점이 있었다.Such post-processing has a problem in that the manufacturing process of the spindle is inconvenient and the manufacturing cost is increased.

도 6을 참조하면, 스핀들이 플랜지의 구분이 없이 이루어지고, 스핀들이 한번에 원형절삭가공하여 넉클에 억지박음 및 열박음됨에 따라, 사용중 변형 발생시 스핀들을 넉클로부터 분리할 수 없는 단점이 있었다.Referring to FIG. 6, there is a disadvantage that the spindle can not be separated from the knock-knoWn when the deformation occurs during use, because the spindle is made without the division of the flange and the spindle is circularly machined in one time to be repressed and shrunk in the knuckle.

또한, 도 7을 참조하면, 스핀들과 플랜지가 주물 또는 분말야금 및 단조로 제조되며, 주물 및 단조의 거친면 중 넉클에 조립되는 접촉면 부분을 후가공하여 제작하여야 하는 공정이 추가되는 불편함이 있었다. Referring to FIG. 7, there is a disadvantage that a spindle and a flange are manufactured by casting or powder metallurgy and forging, and that a process of post-machining a contact surface portion to be assembled to a knuckle among rough surfaces of castings and forgings is added.

이하, 본 발명의 실시예들에 의하여 자동차용 넉클에 결합되는 스핀들 플랜지 제작방법을 설명하기 위한 도면들을 참고하여 본 발명에 대해 설명하도록 한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining a method of manufacturing a spindle flange coupled to an automotive knuckle according to embodiments of the present invention.

본 발명에 따른 자동차용 넉클에 결합되는 스핀들 플랜지 제작방법은, 제1절삭단계(S11), 제2절삭단계(S12) 및 홀형성단계(S13)를 포함한다.A method of manufacturing a spindle flange coupled to a vehicle knuckle according to the present invention includes a first cutting step (S11), a second cutting step (S12), and a hole forming step (S13).

먼저, 제1절삭단계(S11)는, 원기둥 부재(10) 외주면을 절삭가공한다.First, in the first cutting step S11, the outer peripheral surface of the cylindrical member 10 is cut.

즉, 제1절삭단계(S11)는, 일측으로부터 일정길이를 제외한 나머지 외주면을 절삭가공하여 타측에 스핀들(20)을 형성시킨다.That is, in the first cutting step S11, the outer circumferential surface except for a predetermined length is cut from one side, and the spindle 20 is formed on the other side.

한편, 제1절삭단계(S11)는, 원기둥의 일측면에 넉클(40)의 센터홀(42)에 삽입되는 센터가이드(31)가 돌출형성되도록 일정길이를 설정하고, 원기둥의 일측면을 절삭하여 센터가이드(31)를 형성시킨다.In the first cutting step S11, a predetermined length is set so that the center guide 31 inserted into the center hole 42 of the knuckle 40 is protruded from one side of the cylinder, and one side of the cylinder is cut So that the center guide 31 is formed.

이때, 후술할 관통홀(32)과 넉클(40)의 고정공(41)을 관통하여 결합되는 결합부재에 의해 넉클(40)과 플랜지(30)가 고정되나, 결합부재에 의해 넉클(40)의 센터축과 스핀들(20)의 센터축 일치가 정확하게 이루어지지 않을 수 있기 때문에, 넉클(40)의 센터홀(42)에 삽입되는 센터가이드(31)를 형성시켜, 넉클(40)과 스핀들(20)의 센터축이 더욱 정확하게 일치되도록 한다. 여기서, 결합부재로 넉클(40)과 스핀들(20)을 고정시키더라도, 센터가이드(31)에 의해 넉클(40)과 스핀들(20)의 센터축이 일치한 상태로 유지될 수 있다.At this time, the knuckle 40 and the flange 30 are fixed by the coupling member penetrating through the through hole 32 and the fixing hole 41 of the knuckle 40. However, The center guide 31 inserted into the center hole 42 of the knuckle 40 may be formed so that the center axis of the knuckle 40 and the center axis of the spindle 20 may not coincide with each other. 20 to be more precisely aligned. Here, even if the knuckle 40 and the spindle 20 are fixed by the coupling member, the center shaft of the knuckle 40 and the center axis of the spindle 20 can be held by the center guide 31.

제2절삭단계(S12)는, 제1절삭단계(S11)에서 제외되어 절삭가공된 일측을 상하좌우 절삭가공하여 기 설정된 형상의 플랜지(30)를 형성시킨다.In the second cutting step S12, the one side cut away from the first cutting step S11 is cut and processed to form a flange 30 having a predetermined shape.

다시 말해, 원기둥 부재(10)의 외주면을 절삭가공하여 원기둥 부재(10)의 일측에는 플랜지(30), 타측에는 스핀들(20)을 형성시키는 것이다.In other words, the outer peripheral surface of the cylindrical member 10 is cut to form the flange 30 on one side of the cylindrical member 10 and the spindle 20 on the other side.

특히, 제2절삭단계(S12)는, 일직선으로 플랜지(30)의 상하좌우를 절삭할 때, 절삭방향이 교차되는 지점이 원기둥의 평단면적의 내에 위치되어 원기둥의 외주면이 플랜지(30)의 모서리로 이루어진다. Particularly, in the second cutting step S12, when the top, bottom, left and right sides of the flange 30 are cut straight, the intersecting point of the cutting direction is located within the flat area of the cylinder, .

이에 따라, 플랜지(30)의 모서리를 후가공을 하지 않게 되어 플랜지(30) 가공단계가 더욱 원활하게 이루어질 수 있다.As a result, the edges of the flange 30 are not post-processed, and the step of machining the flange 30 can be performed more smoothly.

즉, 넉클(40)과 맞닿는 플랜지(30)는, 기 설정된 크기로 가공되는데, 기 설정된 크기를 맞추기 위해서는 대부분 사각형상의 플랜지(30)를 형성시키고, 사각형상의 플랜지(30) 모서리를 가공하여 라운드지게 형성시키는 후가공을 하게 된다.That is, the flange 30 that contacts the knuckle 40 is formed to have a predetermined size. In order to meet a predetermined size, a rectangular flange 30 is formed in most cases, and a corner of the rectangular flange 30 is machined, Forming process.

후가공을 통해서, 모서리가 아닌 매끄러운 면을 제공함에 따라 작업에 따른 안전사고를 예방할 수 있는 것이다.Through post-processing, it provides a smooth surface, not an edge, so that safety accidents caused by work can be prevented.

여기서, 본 발명의 자동차용 넉클에 결합되는 스핀들 플랜지 제작방법은, 절삭되지 않은 원기둥의 상하좌우를 일직선으로 절삭하되, 절삭방향이 교차되는 지점이 원기둥의 평단면적 내에 위치되도록 하면, 플랜지(30)의 모서리마다 원기둥의 반경과 동일한 반경을 갖는 라운드가 형성되고, 이로 인해, 추가적인 후가공이 필요없게 되는 것이다.A method of manufacturing a spindle flange to be coupled to a vehicle knuckle of the present invention includes the steps of cutting a straight cylinder straight up and down, A round having a radius equal to the radius of the cylinder is formed for each corner, thereby eliminating the need for additional finishing.

홀형성단계(S13)는, 제2절삭단계(S12) 이후에, 플랜지(30)가 맞닿는 넉클(40)의 고정공(41)과 대응되도록 관통홀(32)을 형성시킨다.The hole forming step S13 forms a through hole 32 so as to correspond to the fixing hole 41 of the knuckle 40 to which the flange 30 abuts after the second cutting step S12.

한편, 본 발명에 따른 나사산형성단계(S14)를 더 포함한다.The method further includes a thread forming step (S14) according to the present invention.

나사산형성단계(S14)는, 스핀들(20)의 끝단에 너트(50)가 결합될 수 있도록 나사산(21)을 형성시킨다.In the thread forming step S14, a thread 21 is formed so that the nut 50 can be coupled to the end of the spindle 20. [

너트(50)가 나사산(21)에 결합됨에 따라, 스핀들(20)에 결합되는 하우징(60)이 고정되며, 외력에 의해 유격이 생기면 너트(50)를 더 조여 유격을 최소화할 수 있다.As the nut 50 is coupled to the thread 21, the housing 60 coupled to the spindle 20 is fixed. If a clearance is created by an external force, the nut 50 can be further tightened to minimize the clearance.
