본 고안은 연마기의 공작물회전지지장치에 관한 것으로, 특히 연마기의 그라인더에 의하여 연마되는 공작물이 장착한 회전위치에서 지지될 수 있도록한 연마기의 공작물회전지지장치에 관한 것이다.The present invention relates to a workpiece rotation support device for a polishing machine, and more particularly, to a workpiece rotation support device for a polishing machine that can be supported in the rotational position mounted on the workpiece polished by the grinder of the polishing machine.
종래 연마기의 공작물회전지지장치에 있어서는 원형단면의 공작물을 표면연마하여 그 직경을 정확히 줄이도록하기 위하여 공작물이 두 지지로울러상에 얻히고 하나의 가동로울러가 공작물상에 가압된 상태에서 지지로울러 중 하나를 수동으로 회전시키면서 공작물이 연마기의 그라인더에 의하여 표면연마되게 하였으며 지지로울러 상에 얹히는 공작물은 그 양단이 포인트지지구에 의하여 회전가능한 상태에서 그 축선을 중심으로 하여 지지될수 있게되어 있다. 그러나 지지로울러가 수동으로 회전되므로 저기-기계적으로 회전되는 연마기 그라인더에 공작물이 연마되는 경우 연마량이 일정치 않아 정밀성이 떨어지고 공작물의 축선을 중심으로 이를 지지할수 있도록 포인트지지구는 공작물의 크기 또는 공작물의 연마위치에 따라 적절히 이동될 수 있어야하나 종래기술에 있어서는 간단히 위치조절될 수 없는 점이 있었다.In the conventional rotary work support device of the grinding machine, the workpiece is obtained on two support rollers and the one of the support rollers is pressed on the workpiece in order to reduce the diameter of the workpiece by surface polishing the circular cross section. The workpiece is surface-polished by the grinder of the grinding machine by manually rotating the workpiece, and the workpiece placed on the support roller can be supported about its axis with both ends rotatable by the point support. However, since the support roller is manually rotated, when the workpiece is polished in the grinder grinder that is rotated there- mechanically, the point support is used to reduce the precision and reduce the accuracy of the workpiece. It should be able to move properly according to the position, but in the prior art there was a point that simply can not be adjusted.
본 고안에 있어서는 종래의 이와같은 점을 감안하여 안출한 것으로, 지지로울러를 정확한 회전수의 모우터로 회전구동시켜 공작물의 연마량이 일정하게 유지될 수 있도록하고 공작물의 양단에서 축선을 중심으로하여 이를 지지하는 포인트지지구의 다양한 지지위치의 변화에 적용될 수 있도록한 것인 바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, it is conceived in view of such a conventional situation, and the support roller is rotated by a motor of the correct rotational speed so that the polishing amount of the workpiece can be kept constant and centered on the axis at both ends of the workpiece. It is intended to be applied to the change of various support positions of the supporting point bar, if described in more detail based on the accompanying drawings as follows.

(5) and (6), and the support rollers (9) and (10) are respectively installed on the central circumferential surface of the urine port (7), (8), respectively, and the rear projection (2) of the support (3) The end of the movable lever (13) having the movable roller (12) placed in the support roller (9), the retaining port (7), (8) position of the support roller (9), (10) at the end by fitting the L-shaped handle (11) Is installed at the end of the handle 11 under the contact of the coil spring 14, the slide rod 15 is attached to the support 3 at the lower positions of the support rollers 9 and 10, and the rearward projecting portion ( 2) Spiral coupling of the slide rod fixing bolt 16 in a vertical direction with respect to the slide rod 15 from the lower side of the point, and the point support (18), (19) opposite the point end (17) at both ends of the slide rod (15) ) Is inserted into the through hole 20 formed on the upper side to The movable plates 22 and 23 respectively fixed to the fixing bolts 21 at the fixed position to be fixed to the fixing bolts 25 through the lower vertical holes 24, and one side support roller 9 The pulley 26 is installed on the shaft 5 of the motor, and the pulley 28 of the motor 27 installed on the base 1 is connected to the pulley 28 with a belt 29. Represents water.
이와같은 본 고안은 연마될 공작물(30)을 지지대(3)의 "U"자형 요입부(4)상에 얹고 공작물(30)의 크기에 따라 슬라이드봉 고정볼트(16)를 풀고 슬라이드봉(15)을 해재하여 적절히 이동시키고 이 슬라이드봉(15)의 상단에 고정볼트(25)로 착설된 가동판 (22), (23)을 그 수직장공(24)을 통해 조절하고 그 상측의 통공(20)을 통해 포인트선단(17)을 공작물(30)의 양단 축선중심에 고정시킨다음 고정볼트(51)로 포인트지지구(18) (19)를 고정 하고 고정볼트(25)를 고정하여 슬라이드봉(15)에 대해 가동판(22), (23)을 고정하며 슬라이드봉(15)을 슬라이드봉 고정볼트(16)를 조여 고정한다. 이와 같이 한 경우 공작물(30)은 연마될 부분이 지지로울러(9), (10)상에 얹힌 상태에서 그 축선이 포인트지지구(18), (19)로 정확해 지지된 상태에 놓인다. 이때에 가동로울러(12)를 코일스프링(14)의 작용으로 가동레바(13)가 탄착되게하여 지지로울러(9), (10)상에 놓인 공작물(30)상에 탄지 되게하며, 모우터(27)를 구동시키면 그 풀리(28)와 벨트(29)를 통하여 지지로울러(9)의 축(5)에 착설된 풀리(36)에 회전력이 전달되고 이 지지로울러(9)가 상대측 지지로울러(10)와 가동로울러(12)와의 협동으로 공작물(30)을 회전구동시킨다. 이와같은 공작물(30)은 모우터(27)에 의하여 회전구동되므로 정확한 회전수로 회전하여 연마정도가 일정하게 위치되며, 또한 공작물(30)은 포인트지지구(18), (19)로 정확한 위치에서 그 중심축선이 지지되므로 회전편차가 최소화되어 공작물(30)의 정확한 연마가 이루어질 수 있다.The present invention is such that the workpiece 30 to be polished is placed on the "U" shaped concave portion 4 of the support (3), according to the size of the workpiece 30 to loosen the slide rod fixing bolt 16 and the slide rod (15) ) And move it properly, and adjust the movable plates 22 and 23 installed on the upper end of the slide rod 15 with the fixing bolts 25 through the vertical holes 24 and through the upper holes 20 After fixing the point tip 17 to the axis center of both ends of the work piece 30, the point support 18 and 19 are fixed with the fixing bolt 51 and the fixing bolt 25 is fixed to the slide rod ( Fix the movable plate (22), (23) for the 15) and tighten the slide rod (15) by tightening the slide rod fixing bolt (16). In this case, the workpiece 30 is in a state where the axis is accurately supported by the point supports 18 and 19 while the portion to be polished is placed on the support rollers 9 and 10. At this time, the movable roller 12 is secured by the action of the coil spring 14 so that the movable lever 13 is firmly attached to the support rollers 9 and 10 so as to be supported on the work 30 placed on the support rollers 9 and 10. 27 is driven, the rotational force is transmitted through the pulley 28 and the belt 29 to the pulley 36 mounted on the shaft 5 of the support roller 9, and the support roller 9 is supported by the opposite support roller ( 10) in cooperation with the movable roller 12 to drive the work (30). Since the workpiece 30 is driven by the motor 27, the workpiece 30 is rotated at the correct rotational speed so that the polishing degree is uniformly positioned, and the workpiece 30 is accurately positioned at the point supports 18 and 19. Since the central axis is supported in the rotational deviation is minimized can be accurately polished of the workpiece (30).
