회전수단을 가지는 연마가공물 고정용 지그{Grinding material fixing jig having rotation device}Grinding material fixing jig having rotation means {Grinding material fixing jig having rotation device}

본 발명은 연마가공시, 가공물의 회전을 기계적으로 제어하여 가공작업의 정밀도를 높임과 동시에 다양한 형상의 가공물을 단시간 내에 신속/정확하게 가공토록 함에 그 주안점을 두고 개발된 회전수단을 가지는 연마가공물 고정용 지그에 관한 것이다.The present invention is to fix the polishing workpiece having a rotating means developed with the focus on the mechanical control of the rotation of the workpiece to improve the precision of the machining operation and at the same time to quickly and accurately process a variety of workpieces in a short time. It's about the jig.

일반적으로 연마가공물 고정용 지그(101)는, 내부 공간으로 조임관(11)과 베어링(12)을 가지는 하우징(1)과; 상기 하우징(1)에 관통되어 회전하는 중공축 형태의 회전부재(2)와; 상기 회전부재(2)의 일측단에 설치되어 회전부재(2)를 회전시키는데 사용되는 회전판(도면 미 도시)과; 상기 회전부재(2)의 타측에서 착탈가능하도록 나사결합되는 캡(3)과; 상기 캡(3)에 결합되어 다수개의 척(41)을 연동작동시키는 척작동부재(4)로 구성되는데, 통상 연마기를 통한 가공작업시, 가공물을 견고히 고정시켜 안정된 상태에서 가공이 이루어지도록 하는 것이다.Generally, the jig 101 for fixing a workpiece includes a housing 1 having a tightening pipe 11 and a bearing 12 as an inner space; A hollow shaft rotating member (2) penetrating and rotating through the housing (1); A rotating plate (not shown) installed at one end of the rotating member 2 and used to rotate the rotating member 2; A cap (3) screwed to be detachable from the other side of the rotating member (2); It is composed of a chuck operating member (4) coupled to the cap (3) to operate a plurality of chucks 41, usually in the machining operation through a grinder, to securely fix the workpiece to be processed in a stable state. .

또한 상기 연마가공물 고정용 지그는 회전부재가 일측 회전판에 의해 회전작용하므로 가공물(축 가공물)의 외주연 나사가공, 원뿔형 가공, 다각형 가공시 작업자가 회전판을 이용하여 회전부재를 원하는 각도로 회전시켜 위 다양한 가공형태를 얻을 수 있도록 하고 있다. In addition, since the rotating member is rotated by one side of the rotating plate, the jig for fixing the abrasive workpiece rotates the rotating member at a desired angle by using a rotating plate when the outer circumferential screw processing, the conical processing, and the polygon processing of the workpiece (axial workpiece) are performed. Various processing forms can be obtained.

따라서, 상기 설명에서도 알 수 있듯이 연마가공물 고정용 지그는 연마기를 통한 가공물의 가공작업시, 그 가공물을 위치고정토록 함과 동시에 회전시켜 가공물 외주둘레에 특정형상이 가공되도록 하여 주는 것인데,Therefore, as can be seen from the above description, the jig for fixing the workpiece is to rotate the workpiece and simultaneously rotate the workpiece during the work of the workpiece through the polishing machine so that a specific shape is processed on the outer circumference of the workpiece.

이때, 상기 종래의 연마가공물 고정용 지그는 상기 척작동부재로 가공물을 견고히 고정시켜 주는 이점은 가지고 있으나, 가공물의 회전시 작업자가 직접회전시키는 수동작업이어서, 위 설명한 가공형태 즉, 외주연가공, 원뿔형가공, 다각형 가공 등에서는 정밀도가 현저히 떨어지는 문제가 있었고, 더욱이 다각형의 가공물 가공시 그 가공물의 다각 면을 각각 연마기의 숫돌에 정교하게 일치시키기가 매우 어려워 작업이 장시간 소요됨은 물론 작업의 연속성이 극히 떨어지고, 또 불량이 다수 발생하는 등의 문제를 안고 있었던 실정이었다.At this time, the conventional jig for fixing the workpiece has the advantage of firmly fixing the workpiece with the chuck operation member, but the manual operation by the operator directly rotates when the workpiece is rotated, the above-described processing form, that is, outer peripheral processing, In conical processing and polygonal processing, there was a problem that the precision was remarkably deteriorated. Furthermore, when processing a polygonal workpiece, it is very difficult to precisely match each side of the workpiece with the grindstone of the grinder, which takes a long time and extremely continuous work. It was a situation that had problems such as falling and a large number of defects.

본 발명은 전기한 종래 제반 문제를 일소하기 위하여 발명된 것으로, 특히 종래의 연마가공물 고정용 지그에 있어, 가공물의 회전을 위한 회전부재를 회전모터와 연결하여, 가공물 회전시 인력의 낭비를 막음과 동시에 일정한 회전속도를 제공하여 보다 고른 가공이 이루어지도록 하고, 나아가 상기 회전모터를 컨트롤피씨와 연결시켜 가공물에 대한 회전속도, 회전량, 회전각도 등을 정교하게 자동 제어하므로 가공물의 외주연 나사가공, 원뿔형 가공, 다각형 가공과 같은 다양한 가공작업 들이 정밀하게 실시할 수 있도록 함에 그 기술적 과제의 주안점을 두고 완성하였다.The present invention has been invented to solve the above-mentioned conventional problems, in particular, in the conventional jig for fixing the workpiece, by connecting the rotary member for the rotation of the workpiece with the rotary motor, to prevent waste of manpower when rotating the workpiece and At the same time to provide a constant rotational speed to achieve more even machining, and furthermore, by connecting the rotation motor with the control PC to precisely and automatically control the rotational speed, rotational amount, rotational angle, etc. for the workpiece, so the outer peripheral thread machining of the workpiece, Various technical tasks such as conical machining and polygonal machining can be carried out precisely, with the focus on the technical task.

여기서, 상기 설명한 연마가공물 고정용 지그(101)는 해당 기술분야에서 널리 사용되고 있는 공지의 기술임은 물론 본 발명의 권리범주에 속하지 아니하므로 그에 대한 구성의 상세설명 및 작용설명은 생략한다.Here, the above-described abrasive workpiece fixing jig 101 is a well-known technique widely used in the technical field, and thus does not belong to the scope of the present invention, and thus the detailed description and operation description thereof will be omitted.

따라서, 본 발명은 상기 설명한 종래의 연마가공물 고정용 지그(101)에 있어서, 하우징(1) 측부로 회전모터설치플레이트(5)를 설치하여 컨트롤피씨(51)와 연결된 회전모터(52)를 설치한다.Therefore, the present invention, in the jig 101 for fixing the conventional abrasive workpiece described above, by installing the rotary motor installation plate 5 on the side of the housing 1 to install the rotary motor 52 connected to the control PC 51. do.

이때, 상기 컨트롤피씨(51)는 회전모터(52)의 정/역회전을 제어하기 위한 컨트롤장치로 회전모터(52)의 정회전, 역회전 제어 및 그 속도 제어 그리고 회전량 제어, 및 입력된 각도로 회전 후 멈추게 하는 회전각도제어 등을 실시하게 된다.At this time, the control PC 51 is a control device for controlling the forward / reverse rotation of the rotary motor 52, the forward rotation, reverse rotation control and its speed control and rotation amount control of the rotary motor 52, and Rotation angle control is performed to stop after rotating at an angle.

또한 상기 제어는 작업자가 가공물(102)에 대한 가공 정보를 컨트롤피씨(51)에 입력하여 자동으로 실시되게 한다.In addition, the control allows the operator to automatically input the processing information for the workpiece 102 to the control PC (51).

아울러 상기 회전부재(2) 후방 끝단에는 회전풀리(21)를 설치하여 상기 회전모터(52)의 작동풀리(54)와 벨트(53)로 연결하여 구성한다.In addition, the rear end of the rotating member (2) by installing a rotary pulley 21 is configured by connecting the operation pulley 54 and the belt 53 of the rotary motor 52.

이는, 상기 회전모터(52)에 의해 회전부재(2)가 동시 회전되면서 그 전방부의 척작동부재(4)를 위 제어방법에 따라 회전시키기 위함이다.This is to rotate the chuck operating member 4 of the front portion of the rotating member 2 by the rotary motor 52 in accordance with the above control method.

이상의 구성으로 이루어진 본 발명의 작용을 살펴보면,Looking at the operation of the present invention made of the above configuration,

통상의 방법을 통해 척작동부재(4)로 가공하고자 하는 가공물(102)이 고정되면, 컨트롤피씨(51)에서 회전모터(52)를 제어하여 가공방식에 적합한 방법으로 가공물(102)을 회전시키면서, 연마기에 의한 가공이 이루어지도록 한다.When the workpiece 102 to be processed by the chuck operating member 4 is fixed through a conventional method, the control PC 51 controls the rotating motor 52 while rotating the workpiece 102 in a manner suitable for the processing method. To be processed by the grinding machine.

즉, 가공물(102)의 외주둘레로 나사를 형성할 경우 컨트롤피씨(51)가 회전모터(52)의 회전속도 및 회전량을 제어하여 가공물(102)이 나사형성에 가장 적합한 회전속도 및 회전량으로 회전하여 가공되게 하고 또는 가공물(102) 외주둘레로 다각면을 형성할 경우 컨트롤피씨(51)가 회전모터(52)를 초기 정지위치에서 형성하고자 하는 면의 갯수에 대비되는 각도만큼만 일정하게 반복 회전하여 가공물(102) 외주연에 다각면이 연속가공되도록 하는 것으로, 종래 작업자가 가공물을 수작업을 통해 회전시켰던 것에 반해, 그 정밀도가 매우 높아보아 고품질의 가공물을 얻을 수 있게 되고, 더욱이 회전모터로 가공물의 회전을 제어하므로 다양한 가공작업을 정밀하게 수행할 수 있는 특징을 가지게 된다.That is, when the screw is formed around the outer circumference of the workpiece 102, the control PC 51 controls the rotation speed and the rotation amount of the rotary motor 52, so that the workpiece 102 is the most suitable rotation speed and rotation amount for screw formation To rotate the machine or to form a multi-faced surface around the work piece 102, the control PC 51 repeats only as much as the angle compared to the number of the surface to form the rotating motor 52 at the initial stop position By rotating and allowing the multi-faceted surface to be continuously processed on the outer periphery of the work piece 102, the conventional worker rotates the work piece by hand, and the precision thereof is very high to obtain a high quality work piece. Since the rotation of the workpiece is controlled, various machining operations can be precisely performed.
