The buff wheels 23 and 23 'can be adjusted in the axial direction or the circumferential direction.

상기한 버드 휠(23)(23') 중 피가공물의 진입방향은 모터 축에 1개의 버프 휠을 고정하고 배출방향에는 2개의 버프 휠을 고정하는 것이며, 상기와 같은 반대의 순으로 고정할 수도 있는 것이다.The entry direction of the workpiece among the bird wheels 23 and 23 'is to fix one buff wheel to the motor shaft and two buff wheels to the discharge direction, and to fix in the reverse order as described above. It is.

24는 수평 진동수단으로서, 상기 수평 진동수단(24)은 베드(6)의 상면에, 전방에 걸림턱(26)이 형성된 수평 안내레일(25)을 대향되게 형성하여 지주(13)의 하단에 형성된 지지판(27)을 전후 이동할 수 있게 지지하고, 베드(6)의 후면에 유압모터(29)에 의하여 구동되는 회전축(30)을 설치하여 캠(31)을 설치함과 동시에 상기 캠(31)을 지지판(27)의 후면에 설치된 지지편(33)에 끼워서 캠(31)이 지주(13)를 전후 진동하게 한 것이다.24 is a horizontal vibrating means, the horizontal vibrating means 24 is formed on the upper surface of the bed 6, the horizontal guide rail 25 formed with a locking jaw (26) in the front facing the lower end of the support (13) Support the formed support plate 27 so as to be moved forward and backward, install a rotary shaft 30 driven by the hydraulic motor 29 on the rear of the bed 6 to install a cam 31 and at the same time the cam 31 Is inserted into the support piece 33 provided on the back of the support plate 27 to cause the cam 31 to oscillate back and forth.

그리고 프레임(1)의 일측에는 피가공물 지지부재(33)(33')를 설치하여 그 타단을 지그(5)의 상면과 피가공물의 두께만큼 간극을 두고 위치되게 하여서 지지부재(33)는 피가공물의 중앙부를, 지지부재(33')는 피가공물의 양단부를 지지토록 한 것이다. 미설명부호 34는 연마재 공급수단이고, 35는 버프 휠 커버이다.In addition, the work supporting members 33 and 33 'are installed on one side of the frame 1 so that the other end thereof is positioned with a gap as wide as the upper surface of the jig 5 and the work piece so that the supporting member 33 is The central portion of the workpiece and the support member 33 'are intended to support both ends of the workpiece. Reference numeral 34 is an abrasive supply means, and 35 is a buff wheel cover.

이상과 같은 본 발명은 모터(4)를 구동하여 무단체인(2)을 화살표 방향으로 회전시키면서 지그(5) 위에 피가공물을 재치하고 피가공물을 버프 휠(23)(23') 측으로 이송시키면 지그(5) 위에 재치된 피가공물의 중앙부분은 제7a도와 같이 피가공물 지지부재(33) 에 지지되면서 버프 휠(23)(23')에서 그 양단부가 버핑되고, 무단체인(2)이 계속 회전하여 피가공물이 후방부측의 버프 휠(23)(23')측으로 이송되면 피가공물 지지부재(33')가 제7b도와 같이 그 양단부를 지지하므로서 버프 휠(23)(23')이 피가공물의 중앙부를 버핑하게 되는 것이다.According to the present invention as described above, the workpiece 4 is placed on the jig 5 while the motor 4 is rotated in the direction of the arrow, and the workpiece is transferred to the buff wheels 23, 23 '. (5) The center portion of the workpiece to be placed above is supported by the workpiece support member 33 as shown in FIG. 7A, and both ends thereof are buffed at the buff wheels 23 and 23 ', and the unrolled 2 continues to rotate. When the workpiece is conveyed to the buff wheel 23, 23 'side of the rear side, the workpiece supporting member 33' supports both ends thereof as shown in Fig. 7B, so that the buff wheels 23, 23 'are supported. It will buff the center part.

상기와 같이 무단체인(2)을 화살표 방향으로 회전하여 피가공물을 지지부재 (33)(33')에 지지하고 양단부와 중앙부를 순서대로 버핑함과 동시에 유압모터(29)에 의하여 회전축(30)을 구동하면 회전축(30)에 설치된 캠(31)이 지주(13)의 하단에 형성한 지지판(27)의 지지편(32)을 전후 왕복운동하게 된다.As described above, the member 2 is rotated in the direction of the arrow to support the workpiece on the support members 33 and 33 ', and the both ends and the center portion are buffed in sequence, and the hydraulic shaft 29 is rotated by the hydraulic shaft 29. When driven, the cam 31 provided on the rotating shaft 30 reciprocates back and forth between the support pieces 32 of the support plate 27 formed at the lower end of the support 13.

상기와 같이 지지편(32)이 전후 왕복운동하면 지지판(27)은 베드(6)에 형성된 수평 안내레일(25)을 따라 슬라이딩하므로서 지주(13)도 동시에 전후로 왕복운동하고 지주(13)에 설치된 모터(22)(22')도 왕복운동하기 때문에 버프 휠(23)(23')은 피가공물의 축방향 즉 상기 무단체인(2)의 진행방향과 직각으로 진동하므로서 피가공물의 표면이 정밀하게 버핑되는 것이다.When the support piece 32 reciprocates back and forth as described above, the support plate 27 slides along the horizontal guide rails 25 formed on the bed 6, so that the strut 13 also reciprocates back and forth at the same time and is installed on the strut 13. Since the motors 22 and 22 'also reciprocate, the buff wheels 23 and 23' vibrate at right angles to the axial direction of the workpiece, i. It is buffing.

그리고 피가공물은 무단체인(2)에 지그(5)를 설치하고 상기 지그(5)에 피가공물을 재치하는 것이며, 피가공물의 형상에 따라 지그(5)를 설계하는 것이므로 지그(5)와 버프 휠(23)(23')의 간격 및 지그(5) 위에 재치되는 피가공물의 형상에 따라 버프 휠(23)(23')의 위치를 변경할 필요가 있게 되는 바, 지그(5)와 버프 휠(23)(23')의 간격을 전체적으로 조절할 때에는 모터(9)를 구동하여 웜기어(10) (10')를 회전시키면 회전축(11)(11')이 나사관(12)(12')에서 회전하므로서 베드(6)의 하면 양측에 설치한 슬라이더(7)(7')가 프레임(1)에 설치된 안내레일(8)(8')에서 슬라이딩하므로서 베드(6)가 승강되어 그 간격을 조절하는 것이다.And the workpiece is to install the jig (5) in the unincorporated (2) and to place the workpiece on the jig (5), and to design the jig (5) according to the shape of the workpiece, jig (5) and buff It is necessary to change the positions of the buff wheels 23 and 23 'according to the spacing of the wheels 23 and 23' and the shape of the workpiece placed on the jig 5, so that the jig 5 and the buff wheel To adjust the spacing of the 23 and 23 'as a whole, when the worm gear 10 and the 10' are rotated by driving the motor 9, the rotating shafts 11 and 11 'are screwed in the screw tubes 12 and 12'. By rotating, the slides 7 and 7 'installed on both sides of the bottom of the bed 6 slide on the guide rails 8 and 8' installed on the frame 1, and the bed 6 is lifted to adjust the gap. It is.

또한 지그(5)와 각각의 버프 휠(23)(23')의 간격을 조절하거나 버프 휠(23) (23')을 축방향으로 이동시킬 때에는 이송 스크류(17)를 회전하면 지주(13)에 지지된 수직 지지부재(15)(16)가 승강되고, 이송 스크류(21)를 회전시키면 수직 지지부재(15)(16)에 지지된 수평 지지부재(19)(20)가 전후로 이동되므로서 다양한 형상의 피가공물을 버핑할 수 있는 것이다.In addition, when adjusting the distance between the jig 5 and each of the buff wheels 23 and 23 'or moving the buff wheels 23 and 23' in the axial direction, the prop 13 is rotated by rotating the feed screw 17. The vertical support members 15 and 16 supported at the upper and lower sides are rotated, and when the feed screw 21 is rotated, the horizontal support members 19 and 20 supported at the vertical support members 15 and 16 are moved back and forth. It is possible to buff workpieces of various shapes.

이상과 같이 본 발명은 도어, 조리용기 등의 손잡이 등과 같이 대칭 또는 비대칭형상의 피가공물을 그 형상 및 크기에 구애 받지않고 자동으로 버핑할 수 있으므로 안전사고가 방지되며, 생산성이 향상되어 원가가 절감되고, 작업자가 분진을 호흡하지 않게 되어 청결하고 위생적으로 작업을 할 수 있게 되는 등의 효과가 있는 것이다.As described above, the present invention can automatically buff workpieces of symmetrical or asymmetrical shapes, such as handles of doors, cooking vessels, etc., regardless of their shape and size, thereby preventing safety accidents and improving productivity, thereby reducing costs. In addition, the worker does not breathe dust, so that the work can be clean and hygienic.
