Description

다중 편심 지그 {multitude eccentric jig}Multi Eccentric Jig {multitude eccentric jig}

본 발명은 다중 편심 지그에 관한 것으로서, 더 상세하게는 다수의 작업중심을 갖는 가공대상물의 작업위치를 용이하게 세팅할 수 있도록 형성된 다중 편심 지그에 관한 것이다.The present invention relates to a multiple eccentric jig, and more particularly, to a multiple eccentric jig formed to easily set the working position of a workpiece having a plurality of work centers.

종래의 복수의 조(jaw)를 구비한 척을 이용하여 상기와 같은 공작물을 편심된 위치를 중심으로 회전하도록 고정하고자 할 경우에는 회전시키고자 하는 공작물의 편심된 위치가 척의 회전중심에 위치하도록 각각의 조(jaw)를 적당한 길이로 조절하여 공작물을 고정하여야 한다. In the case where the workpiece is to be fixed to rotate about an eccentric position using a conventional chuck with a plurality of jaws, the eccentric position of the workpiece to be rotated is located at the center of rotation of the chuck. The jaw must be adjusted to the appropriate length to fix the workpiece.

그러나 이러한 작업은 대단히 숙련된 작업자가 아니면 정확하게 편심된 위치를 조절하여 고정할 수 없으며, 많은 양의 공작물을 가공하여야 할 경우에는 생산성이 극히 낮아지게 된다.However, this work can not be fixed by adjusting the exact eccentric position unless a very skilled worker, the productivity will be extremely low when a large amount of workpiece is to be processed.

이러한 문제점에 대한 대안으로 등록특허 제10-0563580호에는 편심가공용 유압 콜릿척 조립체가 개시되어 있다. As an alternative to this problem, Patent No. 10-0563580 discloses a hydraulic collet chuck assembly for eccentric machining.

상기 종래의 편심가공용 유압 콜릿척 조립체는 자동차 등에 사용되는 진공펌프의 임펠러를 편심되도록 지지하는 진공펌프의 사이드 프레임을 기계가공할 수 있 도록 형성된 것이다.The conventional eccentric hydraulic collet chuck assembly is formed to be capable of machining the side frame of the vacuum pump for supporting the impeller of the vacuum pump used in automobiles and the like eccentrically.

그러나 이러한 종래의 편심가공용 유압 콜릿척 조립체는 하나의 가공대상물에 대하여 다수개의 작업중심이 설정될 필요가 있을 때에는 역시 종래의 가공 방법과 마찬가지로 매번 편심된 위치를 조절할 수 밖에 없다.However, such a conventional eccentric hydraulic collet chuck assembly is required to adjust the eccentric position every time, as in the conventional machining method, when a plurality of work centers need to be set for one object.

따라서 다수개의 작업 중심을 갖는 가공대상물을 용이하게 가공할 수 있도록 가공대상물의 가공중심을 용이하게 세팅할 수 있는 적절한 수단이 필요하였다.Therefore, an appropriate means for easily setting the processing center of the processing object was required to easily process the processing object having a plurality of work centers.

본 발명은 다수개의 가공중심을 갖는 가공대상물에 있어서, 각각의 가공중심을 용이하게 세팅할 수 있도록 형성된 다중 편심 지그를 제공하는 것에 그 목적이 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a multi-eccentric jig formed to easily set each machining center in a workpiece having a plurality of machining centers.

본 발명에 따른 다중 편심 지그는 척에 고정되며 복수개의 가공중심을 갖는 가공대상물을 지지하는 것으로서, 상기 지지척에 고정되는 베이스부와, 상기 가공대상물과 결합되는 결합부와, 상기 베이스부와 결합부를 상호 연결하도록 연장되는 바디를 구비하며, 상기 바디는 상기 가공대상물의 가공중심과 상기 척의 회전중심을 일치시키기 위한 세팅부들을 포함한다.The multi-eccentric jig according to the present invention is to be fixed to the chuck to support a workpiece having a plurality of processing centers, the base portion fixed to the support chuck, the coupling portion coupled to the workpiece and the base portion is coupled And a body extending to interconnect the parts, wherein the body includes setting parts for matching the machining center of the workpiece with the rotation center of the chuck.

상기 세팅부는 원통형으로 형성되며, 상기 각각의 세팅부는 회전중심축이 상기 가공대상물의 각각의 가공중심을 통과하도록 나란하게 연장되게 형성되는 것이 바람직하다.The setting unit is formed in a cylindrical shape, each of the setting unit is preferably formed so as to extend side by side so that the rotational center axis passes through each processing center of the workpiece.

본 발명에 따른 다중 편심 지그는 복수개의 가공중심을 갖는 가공대상물을 가공할 때, 각각의 가공중심과 주축의 회전 중심이 일치하도록 가공대상물을 세팅하기 용이하며, 이에 따라 생산성이 향상되고 제품의 불량 발생을 최소화할 수 있는 이점을 제공한다.Multi-eccentric jig according to the present invention, when processing a workpiece having a plurality of processing centers, it is easy to set the processing object to match the center of rotation of each processing center and the main axis, thereby improving productivity and product defects It offers the advantage of minimizing the occurrence.

이하, 첨부된 도면을 참조하여 본 발명에 따른 다중 편심 지그를 더욱 상세하게 설명하면 다음과 같다.Hereinafter, a multi-eccentric jig according to the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 3은 본 발명에 따른 다중 편심 지그(10)의 일 실시예가 도시되어 있다.1 to 3 show one embodiment of a multiple eccentric jig 10 according to the present invention.

본 실시예의 가공대상물(6)은 연삭에 의해 가공면에 다수개의 돌기를 형성하기 위한 것이다.The object to be processed 6 in this embodiment is for forming a plurality of protrusions on the machined surface by grinding.

주축(1)에 마그네틱 척(2)이 설치되어 있고, 다중 편심 지그(10)는 일단이 상기 마그네틱척(2)에 결합되어 있으며, 다중 편심 지그(10)의 타단에는 가공대상물(6)이 장착되어 있다.Magnetic chuck (2) is provided on the main shaft (1), one end of the multiple eccentric jig 10 is coupled to the magnetic chuck (2), the other end of the multiple eccentric jig (10) It is installed.

다중 편심 지그(10)는 상기 마그네틱척(2)에 고정되는 베이스부(11)와, 가공대상물(6)이 결합되는 결합부(12) 및 베이스부(11)와 결합부(12) 사이를 연결하는 바디(13)를 포함한다.The multi-eccentric jig 10 has a base portion 11 fixed to the magnetic chuck 2, a coupling portion 12 to which the workpiece 6 is coupled, and a base portion 11 and a coupling portion 12. It comprises a body 13 for connecting.

상기 바디(13)는 가공대상물(6)의 가공중심과 척(2)의 회전중심을 일치시키기 위한 세팅부(14)를 포함하는데, 세팅부(14)는 원통형으로 형성되어 있다. 세팅부(14)는 각각 회전중심을 갖는데, 이 회전중심들은 각각 가공대상물(6)의 가공중심들과 대응되도록 형성되어 있다.The body 13 includes a setting portion 14 for matching the machining center of the workpiece 6 with the rotational center of the chuck 2, which is formed in a cylindrical shape. The setting portions 14 each have a center of rotation, which is formed so as to correspond to the centers of processing of the workpiece 6, respectively.

다시 말해서, 세팅부(14)의 회전중심의 연장선들은 모두 나란한 방향으로 연장되며, 각각의 연장선들은 모두 가공대상물(6)의 복수개의 가공중심을 통과하도록 연장된다.In other words, the extension lines of the rotation center of the setting portion 14 all extend in parallel directions, and each of the extension lines extends through the plurality of processing centers of the object to be processed 6.

따라서 가공대상물(6)을 가공할 경우, 가공대상물(6)의 선택된 가공중심에 대응하는 세팅부(14)의 회전중심과 척(2)의 회전중심을 일치시키면 가공대상물(6)은 선택된 가공중심을 중심으로 회전하게 됨으로써 사용자가 원하는 정위치에서 연삭 작업이 이루어질 수 있다.Therefore, when machining the object 6, if the center of rotation of the setting unit 14 corresponding to the selected center of processing of the workpiece 6 and the center of rotation of the chuck 2 coincide, the object to be processed 6 By rotating around the center, the grinding operation may be performed at a desired position of the user.

바디(13)의 회전중심과 척(2)의 회전중심을 일치시키는 것은 인디케이터(4)에 의해서 이루어진다.Matching the center of rotation of the body 13 with the center of rotation of the chuck 2 is made by the indicator 4.

선택된 가공중심에 대응하는 회전중심을 갖는 세팅부(14)의 외주면에 인디케이터(4)의 탐촉자(5)를 접촉시킨 다음 척(2)을 회전시키면, 해당 세팅부(14)의 회전중심과 척(2)의 회전중심이 일치하지 않는 경우 인디케이터(4)의 탐촉자(5)가 진퇴하게 되며, 인디케이터(4)에서 이를 게이지를 통해 표시하기 때문에 세팅부(14)의 회전중심과 척(2)의 회전중심의 일치 여부를 육안으로 확인할 수 있다.When the transducer 5 of the indicator 4 is brought into contact with the outer circumferential surface of the setting unit 14 having the rotation center corresponding to the selected machining center, and then the chuck 2 is rotated, the rotation center and the chuck of the setting unit 14 are rotated. If the center of rotation of (2) does not coincide, the transducer 5 of the indicator 4 moves forward and backward, and the indicator 4 displays it through a gauge, so that the center of rotation of the setting unit 14 and the chuck 2 You can visually check whether the rotation center of

반면 척(2)의 회전중심과 탐촉자(5)가 접촉한 세팅부(14)의 회전중심이 일치하게 되는 경우 탐촉자(5)는 진퇴하지 않고 위치가 고정된다. 따라서 인디케이터(4)를 이용해 바디(13)의 회전중심과 척(2)의 회전중심을 용이하게 일치시킬 수 있다.On the other hand, when the center of rotation of the chuck 2 and the center of rotation of the setting unit 14 in contact with the transducer 5 coincide with each other, the position of the transducer 5 is fixed without retreating. Therefore, the indicator 4 can be easily matched to the center of rotation of the body 13 and the center of rotation of the chuck (2).

물론 상기 세팅부(14)의 회전중심과 척(2)의 회전중심의 일치여부를 인디케이터(4)를 통해 확인하게 되므로 세팅부(14)의 외주면은 정원의 곡률을 따라 연장되며, 정삭 가공을 통해 표면이 매끄럽게 형성되도록 하는 것이 바람직하다.Of course, it is possible to check whether the center of rotation of the setting unit 14 and the center of rotation of the chuck 2 are matched by the indicator 4, so that the outer circumferential surface of the setting unit 14 extends along the curvature of the garden and is finished. It is desirable to make the surface smoothly through.

본 실시예를 통해 본 발명의 다중 편심 지그(10)를 통한 가공중심의 세팅과정을 설명하면 다음과 같다.Referring to the process of setting the processing center through the multi-eccentric jig 10 of the present invention through the present embodiment as follows.

먼저 가공대상물(6)의 가공면에 형성할 돌기들 중 하나를 가공하기 위해 가 공중심이 척(2)의 회전중심과 일치하도록 세팅하게 되는데, 상기 선택된 가공중심과 일치하는 회전중심을 갖는 세팅부(14)의 외주면에 인디케이터(4)의 탐촉자(5)를 접촉시킨 후 척(2)을 회전시켜 탐촉자(5)의 진퇴여부를 확인한다.First, in order to process one of the projections to be formed on the machining surface of the object 6, the air center is set to coincide with the center of rotation of the chuck 2, and the setting unit having a center of rotation coinciding with the selected center of machining. After contacting the transducer 5 of the indicator 4 to the outer circumferential surface of 14, the chuck 2 is rotated to check whether the transducer 5 is moved forward and backward.

탐촉자(5)가 진퇴되지 않을 때까지 다중 편심 지그(10)를 이동시켜 선택된 세팅부(14)의 회전중심과 척(2)의 회전중심을 일치시킨다.The multiple eccentric jig 10 is moved until the transducer 5 is not advanced to coincide with the center of rotation of the selected setting unit 14 and the center of rotation of the chuck 2.

선택된 세팅부(14)의 회전중심은 선택된 가공중심과 동일하므로 이렇게 다중 편심 지그(10)가 세팅된 상태로 척(2)이 회전하면 가공대상물(6)은 선택된 가공중심을 중심으로 회전하게 되며, 연삭공구(3)를 접촉시켜 의도한 위치에서 가공대상물(6)을 가공할 수 있다.Since the center of rotation of the selected setting unit 14 is the same as the center of the selected machining, when the chuck 2 is rotated with the multi-eccentric jig 10 set as described above, the workpiece 6 is rotated about the selected machining center. The grinding tool 3 can be brought into contact with each other to process the object to be machined 6 at the intended position.

일부분의 가공이 완료되면 새로운 가공중심을 다시 세팅한다.When part machining is complete, set new machining center again.

앞선 가공중심 세팅과정과 마찬가지로 새 가공 지점의 가공중심에 대응하는 회전중심을 갖는 세팅부(14)의 외주면에 인디케이터(4)의 탐촉자(5)를 접촉시켜 탐촉자(5)가 진퇴되지 않도록 다중 편심 지그(10)를 세팅하면 척(2)의 회전중심과 가공대상물(6)의 가공중심이 일치하게 되므로 새로운 가공중심을 기준으로 가공대상물(6)이 회전하면서 가공면에 연삭이 이루어진다.As in the previous machining center setting process, the eccentric of the indicator 4 is brought into contact with the outer circumferential surface of the setting part 14 having the rotation center corresponding to the machining center of the new machining point so that the transducer 5 is not retracted. When the jig 10 is set, the center of rotation of the chuck 2 and the center of machining of the workpiece 6 coincide with each other, and thus grinding is performed on the machining surface while the workpiece 6 is rotated based on the new machining center.

본 실시예에서는 연삭 가공을 하는 공작기계에 다중 편심 지그(10)가 설치되었으나, 다수개의 가공중심을 갖는 가공대상물(6)을 지지하기 위해 다양한 가공을 실시하는 공작기계에 본 발명의 다중 편심 지그(10)가 설치될 수도 있다.In the present embodiment, the multi-eccentric jig 10 is installed in a machine tool for grinding, but the multi-eccentric jig of the present invention is applied to a machine tool that performs a variety of processing to support the workpiece 6 having a plurality of machining centers. 10 may be provided.

이렇게 본 발명에 따른 다중 편심 지그(10)는 가공대상물(6)의 각각의 가공중심에 대응하는 회전중심을 갖는 복수개의 세팅부(14)가 마련되어 있으므로 이 세 팅부(14)의 회전중심과 척(2)의 회전중심을 일치시킴으로써 가공대상물(6)의 가공중심 세팅을 용이하게 실시할 수 있다.Thus, since the multiple eccentric jig 10 according to the present invention is provided with a plurality of setting portions 14 having a rotational center corresponding to each machining center of the workpiece 6, the center of rotation and the chuck of the setting part 14 are provided. By coinciding the rotation center of (2), the processing center setting of the object 6 can be easily performed.
