본 고안은 버핑 장치에 관한 것이며 상세하게는 알류미늄판이나 스테인레스판 등을 재료로 하여 제조된 소형 전자 제품의 외장재, 휴대폰의 금속 외장재, 시계용 메탈 등을 버핑하는 장치에 관한 것으로서 상기 제품을 제조할 때 일정 형상으로 성형한 후 광택을 부여하기 위하여 버핑을 실시하고 있는바 종래에는 작업자가 작업물이 세팅된 홀더를 직접 잡고 모터의 회전축의 일단 또는 양단에 버핑휠을 설치하여 버핑기에서 수작업으로 버핑하고 있다.The present invention relates to a buffing device, and more particularly, to an apparatus for buffing an exterior material of a small electronic product manufactured from an aluminum plate or a stainless plate, a metal exterior material of a mobile phone, a metal for a watch, and the like. When molding to a certain shape when buffing to give gloss, conventionally, the operator directly grabs the holder with the workpiece set and installs buffing wheels at one end or both ends of the rotating shaft of the motor to buff them manually in the buffing machine. Doing.

그러나 상기와 같이 수작업으로 버핑을 실시하면 안전사고의 위험이 있을 뿐 아니라 작업형태가 작업자의 체력을 많이 소모함으로서 생산성이 낮아 원가가 상승되고 버핑 시에 발생되는 분진을 작업자가 호흡하므로서 건강에도 좋지 못한 문제점이 있어 작업을 기피하고 있는 실정이다. 본 고안은 상기한 문제점을 해결하여 휴대폰의 외장 금속재와 같이 소형 스테인레스 판재의 피 가공물을 파지한 버핑 지그를 작업자가 로딩, 언로딩만으로 버핑 작업이 가능하므로 안전사고를 예방하고 생산성을 향상시키며 작업자가 분진을 호흡하지 않도록 한 버핑 장치를 제공하는 것을 목적으로 한다.However, if the buffing is performed manually as described above, there is a risk of safety accidents, and the work type consumes much of the worker's physical strength, resulting in low productivity due to low productivity, and unfavorable health as the worker breathes dust generated during buffing. There is a problem to avoid work. The present invention solves the above problems by allowing the operator to buff the buffing jig holding the workpiece of the small stainless steel plate, such as the exterior metal of the mobile phone, by only loading and unloading, thereby preventing safety accidents and improving productivity. It is an object to provide a buffing device that does not breathe dust.

The caster 104 is attached to the lower four parts of the lower plate 102 of the frame to enable position movement and level adjustment, and the motor-integrated worm which is a driving means for rotating the rotary table 301 in the center of the upper surface of the lower plate 102. The reducer 302 is fixed, and the jack screw 201, which is a means for moving the tool post up and down, is fixed to the outside of the upper surface of the lower plate 102. The motor-integrated worm reducer 302 and the jack screw 201 and The workpiece rotating motor 303 was fixed to provide a driving means for returning the workpiece to the buffing work circumferentially surrounded by the outer portion of the rotary table 301. The two pillars 103 located in front of the pillars 103 are attached with a plate 105 to attach a vertically adjustable rotary knob 202 to transmit the rotational force to the driving portion of the jack screw 201 for the shank east of the tool post. Both ends of the plate 105 prevent dust from entering the inside and attach the cover 106 considering the appearance, and the central part of the plate 105 has a structure for internal wiring and inspection holes. In use, a detachable inspection cover 107 was attached.

또한 상판(101)의 중앙부에는 로터리 테이블(301)의 회전을 가능하도록 로터리 테이블(301)을 고정시킨 샤프트(304)을 끼운 상하 두개의 앵귤러 타입 로울러 베어링(305)을 조립한 하우징(306)을 볼트로 고정토록 했으며 상판(101)의 바깥쪽에는 공구대 부분의 상하 이동시 가이드 수단을 제공하고 회전을 방지 할 수 있도록 한 키(218)를 고정시킨 샤프트(219)를 상하로 슬라이드 가능토록 안내면을 제공한 하우징(220)을 넣어서 볼트로 고정 시킬 수 있는 구멍을 가진 구조로 되어 있으며 상판(101)의 로터리 테이블 최 외측 원주 바로 아래 부근에는 버핑 작업 시 피 가공물을 회전 시키는 구동력을 전달 할 수 있는 환 벨트(307)를 연결하여 구동 시킬 수 있도록 한 구동 풀리와 회전부위의 간섭 방지를 위한 아이들 풀리(308)를 부착하였다, 또한 공구대부는 버핑 휠(203)을 지지하고 회전시킬 수 있도록 너트(204),베어링(205),칼럼(206),풀리(207)을 조립한 샤프트(208)를 수납한 블록(209)을 볼트로 모터 베이스(210)에 체결하고 이 모터 베이스(210) 윗 쪽에는 버핑 휠 구동용 모터(211)를 부착토록 했으며 브이벨트로 버핑 휠(203)에 구동 모터의 회전력을 전달하도록 하는 구조로 고안하였다. 또한 이 공구대를 수평으로 전후진 할 수 있도록 수동 핸들(212)의 회전력을 전 후진 방향으로의 직선 왕복 운동으로 전환하는 수단인 리이드 스크류(213)의 이송 너트(214)를 슬라이드(215)에 고정하였으며 이 슬라이드(215)를 가이드(216)로 안내하였고 이 슬라이드(215)와 공구대부의 모터 베이스(210)와 볼트를 체결하여 공구대가 전 후진 직선 이송이 가능토록 구성하였다. 또한 공작물을 수납한 버핑지그를 올려놓고 회전 시킬 수 있는 구조를 가진 워크 홀더(309)는 풀리(310)와 결합된 샤프트(311)와 상하 베어링과 버핑 시 발생하는 먼지의 유입을 방지 할 수 있도록 한 구조를 가진 테이블 커버(108)를 스냅링(312)과 볼트로 조립하여 로터리 테이블(301)에 볼트로 빙 둘러 다수 개를 조립 부착하였다. 또한 작업대는 작업성을 고려하여 가운데가 공작물에 가깝도록 한 형상의 플레이트(109)를 스테이(110)로 상판(101)에 고정하였다. 얇은 박판의 금속재의 버핑 작업에 있어서 버핑 지그에 피 가공물을 재치하는 것이며 피 가공물의 형상에 따라 버핑 지그를 설계 제작하는 것이므로 버핑 지그와 버핑 휠(203)의 간격 및 버핑 지그위에 재치되는 피 가공물의 형상에 따라 버핑 휠(203)의 위치를 상하 좌우를 변경시킬 필요가 있어서 버핑 휠 상하 이송장치와 전후 이송 장치를 구성했으며 또한 피 가공물이 재치된 버핑 지그를 회전시켜야만 양질의 버핑 품질을 얻을 수 있으므로 상기와 같은 구성으로 로터리형의 버핑 장치를 고안하였다.In the center of the upper plate 101, a housing 306 in which two upper and lower angular type roller bearings 305 in which the rotary table 301 is fixed is fitted with the shaft 304 fixed to enable the rotary table 301 to be rotated. The guide surface is fixed to the outside of the upper plate 101 so that the guide surface can be slid up and down on the outside of the upper plate 101 to provide a guide means for moving the tool bar up and down, and to fix the shaft 219 fixed to the key 218 to prevent rotation. It has a structure that has a hole that can be fixed to the bolt by inserting the housing 220 provided, and the ring that can transmit the driving force to rotate the workpiece during the buffing work in the vicinity of the outermost circumference of the rotary table of the upper plate 101 A driving pulley for connecting and driving the belt 307 and an idle pulley 308 for preventing interference of the rotating part are attached. In addition, the tool rest is a buffing wheel 203. Fasten the block 209 containing the nut 204, the bearing 205, the column 206, and the shaft 208 assembled with the pulley 207 to the motor base 210 with bolts. The buffing wheel driving motor 211 is attached to the upper side of the motor base 210 and is designed to transfer the rotational force of the driving motor to the buffing wheel 203 with a V-belt. Further, the feed nut 214 of the lead screw 213, which is a means for converting the rotational force of the manual handle 212 into a linear reciprocating motion in the forward and backward directions, so that the tool post can be moved back and forth horizontally, the slide 215 The slide 215 was guided to the guide 216, and the slide 215 and the motor base 210 of the tool rest were fastened to the bolt so that the tool rest could be transported straight backward. In addition, the work holder 309 has a structure that can be rotated by placing the buffing jig holding the workpiece to prevent the inflow of dust generated when the shaft 311 and the upper and lower bearings and buffing combined with the pulley 310. A table cover 108 having a structure was assembled with a snap ring 312 and bolts, and a plurality of pieces were assembled around the rotary table 301 with bolts. In addition, the worktable fixed the plate 109 having a shape 110 such that the center thereof was close to the workpiece in consideration of workability, with the stay 110 on the top plate 101. In the buffing work of thin thin metal materials, the workpiece is placed on the buffing jig and the buffing jig is designed and manufactured according to the shape of the workpiece. Therefore, the gap between the buffing jig and the buffing wheel 203 and the workpiece to be placed on the buffing jig Since the position of the buffing wheel 203 needs to be changed up, down, left, and right according to the shape, the buffing wheel up and down feeder and the forward and backward feeder are configured, and the buffing jig in which the workpiece is placed can be rotated to obtain high quality buffing quality. The rotary type buffing device was devised as described above.

이상 상기한 바와 같은 본 고안은 휴대폰의 외장 금속재등과 같은 형상의 피 가공물을 피 가공물이 재치된 버핑 지그를 로딩 언로딩만 함으로써 연속적으로 자동 버핑 할 수 있으므로 안전사고가 방지되며 생산성이 향상되어 원가가 절감되고 작업자가 분진을 호흡하지 않게 되어 청결하고 위생적으로 작업을 할수있게 되는 등의 효과가 있다.As described above, the present invention can continuously buff a workpiece of the same shape as the exterior metal of a mobile phone by simply unloading the buffing jig in which the workpiece is placed, thereby preventing safety accidents and improving productivity. Is reduced, and the worker does not breathe dust, thereby making the work clean and hygienic.
