본 고안은 유리섬유나 탄소섬유등을 합성수지에 함침시킨 후 인발, 건조, 절단시킨 낚시대 끝대의 반제품을 최종적으로 연마 가공하여 낚시대의 끝대로 이용 가능하게 되는 낚시대의 끝대 가공용 센터리스 연삭기에 관한 것이다.The present invention relates to a centerless grinding machine for processing the tip of a fishing rod, which is finally polished by processing a semi-finished product of a fishing rod tip after impregnating glass fiber or carbon fiber with a synthetic resin and finally drawing, drying and cutting.
일반적으로 센터리스 연삭기(ceterless grinding machine)는 센터를 사용하지 않고, 연삭용 숫돌차 외에 가공물에 회전과 이송을 일으키는 조정숫돌바퀴를 사용하여 가늘고 긴 환봉을 연삭하는 것으로서 가공물의 이송은 숫돌차 추와 중심에 대해서 조정숫돌바퀴의 중심을 조금 기울여 가공물을 회전시키면서 조금씩 축방향으로 움직이도록 하는 것인바, 종래의 센터리스연삭기는 가공물을 투입하거나 가공된 가공물을 투출할 때, 조정숫돌바퀴의 횡방향 이동이 스크류 회전운동에 의해서 이루어지고 있다. 이에 의해 스크류 회전운동시 비교적 많은 시간이 소요되므로서 생산성을 향상시켜주기가 어려울 뿐 아니라 가공물의 급송동작과의 연계선을 지속시켜 줄수 없고 작업성이 매우 나쁜 제반의 문제점이 있었다.In general, a centerless grinding machine uses a grinding wheel to grind and elongate a round bar without using a center and using wheels for turning and transporting the workpiece in addition to grinding wheels for grinding. Tilt the center of the adjustment wheel with respect to the center to move the workpiece little by little in the axial direction. Conventional centerless grinding machines move the adjustment wheel in the lateral direction when inserting the workpiece or discharging the processed workpiece. This screw rotation is achieved. As a result, the screw rotational movement takes a relatively long time, and it is difficult to improve the productivity, and there is a problem in that the workability cannot be maintained and the workability is very poor.
본 고안은 이와 같은 종래의 제반 문제점들을 해결하기 위한 것으로서 그 목적은 가공물의 투입, 투출시 조정 숫돌바퀴의 횡방향 이동을 캠운동기구로 실시함으로서 이동시간을 대폭 단축시켜 고속운동이 가능하도록 함과, 캠운동기구와 동일 축선상에 가공물의 급송을 제어하는 급송제어캠을 설치하므로서 가공물의 급송과 조정숫돌바퀴의 이동을 연계시켜서 작업능률을 향상시켜 줄 수 있음을 특징으로 하는 낚시대의 끝대 가공용 센터리스 연삭기를 제공하는데 있다.The present invention has been made to solve such problems in the related art, and its purpose is to carry out the lateral movement of the adjustment wheels with the cam movement mechanism when inserting and discharging the workpiece, thereby greatly reducing the movement time and enabling high-speed movement. The center for processing the tip of the fishing rod characterized by the fact that the feed control cam for controlling the feeding of the workpiece on the same axis as the cam motion mechanism can be linked to the feeding of the workpiece and the movement of the adjustment wheel to improve the work efficiency. It is to provide a lease grinding machine.

끝대급송제어용 캠(14)에는 리미트스위치(20)가 접속되어 제1도에서 쇄선으로 표시된 바와 같은 끝대급송장치(21)에서 반제품 상태의 끝대(4)를 1개씩 상기 지지판(3)으로 밀어 인입시켜 주는 플런저(22)를 수평왕복운동 시켜주는 에어실린더(23)에 작동공압을 공급해주는 고압제어기(24)를 작동하도록 하며,A limit switch 20 is connected to the end feed control cam 14 so that the end feed 4 of the semi-finished state is pushed into the support plate 3 one by one in the end feed device 21 as indicated by the broken line in FIG. To operate the high-pressure controller 24 for supplying the working air pressure to the air cylinder 23 for horizontal reciprocating movement of the plunger 22,
끝대급송장치(21)는 반제품상태의 끝대(4)가 투입되는 홉퍼(25)와 끝대(4)의 길이 맞춤 이동이 가능한 가동측판(26)을 가진 것으로서 끝대를 연속적으로 본 고안의 연삭기로 공급해주는 것이다.The end feeder 21 has a hopper 25 into which the end 4 of the semi-finished state is inserted and a movable side plate 26 capable of adjusting the length of the end 4, and continuously supplying the end to the grinder of the present invention. It is.
상기한 바와 같은 조정숫돌바퀴(2)의 이동제어용 캠(13)과 끝대급송제어용 캠(14)의 상관관계를 보다 구체적으로 설명하면 다음과 같다.The correlation between the movement control cam 13 and the end feed control cam 14 of the adjustment wheel 2 as described above will be described in more detail as follows.
조정숫돌바퀴(2)의 이동제어용 캠(13)과 끝대급송제어용캠(14)은 같은 회전축(11)상에서 각 장축방향과 단축방향의 반대로 고정되어 있다. 즉, 조정숫돌바퀴(2)의 이동제어캠(13)이 장축방향쪽의 작동테이블(5) 로울러(6)와 접하면서 작동테이블(5)을 밀어 조정숫돌바퀴(2)를 연삭용 숫돌차(1)쪽으로 이동 회전할때 끝대(4)를 연삭가공함과, 끝대이송제어용캠(14)은 장축방향쪽이 리미트스위치(20)의 압력뿔(20')을 밀어내어 리미트스위치(20)를 OFF상태로 끝대급송장치(21)의 작동을 멈추게 하고, 이와 반대로 조정숫돌바퀴(2)의 이동제어캠(13)이 단축방향쪽의 작동테이블(5)을 밀지 못하게 될 경우에는 작동테이블(5)이 탄축코일스프링(8)의 복원력에 의해 조정숫돌바퀴(2)가 연삭용 숫돌차(1)로부터 멀어지게 됨과 함께, 끝대 이송제어캠(14)의 단축방향쪽이 리미트스위치(20)의 압력뿔(20')을 밀던 힘이 제거됨으로서 압력스위치(20)는 ON상태로 끝대급송장치(21)가 작동을 개시하여 반제품인 끝대(4) 하나를 연삭용 숫돌차(1)와 조정숫돌바퀴(2) 사이의 지지판(3)으로 밀어 주게 되는 것이다.The movement control cam 13 and the end feed control cam 14 of the adjustment wheel 2 are fixed opposite to each other in the major axis direction and the minor axis direction on the same rotation shaft 11. That is, while the movement control cam 13 of the adjustment wheel 2 is in contact with the operation table 5 roller 6 in the long axis direction, the operation wheel 5 is pushed to push the adjustment wheel 2 to the grinding wheel. (1) When the rotation is rotated toward the end (4) grinding, the end feed control cam (14) in the long axis direction pushes the pressure cone 20 'of the limit switch 20 limit switch (20) Stops the operation of the end feeder 21 and, on the contrary, when the movement control cam 13 of the adjustment wheel 2 does not push the operation table 5 in the shorter direction, the operation table ( 5) The adjustment wheel 2 is moved away from the grinding wheel 1 for grinding by the restoring force of the shaft coil spring 8, and the short direction of the end feed control cam 14 is the limit switch 20. By removing the force pushing the pressure horn 20 'of the pressure switch 20 in the ON state, the end feeder 21 starts to operate the semi-finished end (4) Will be granted push the support plate (3) between turning the grinding wheel 1 and the adjustment grindstone wheel (2).
이와같은 일련의 작동상태는 제3도와 제4도에 표현된 도면을 참조하면 더욱 쉽게 이해할 수 있다.Such a series of operating states can be more easily understood with reference to the figures represented in FIGS. 3 and 4.
본 고안에 의한 연삭기는 가공물인 끝대(4)의 투입과 가공된 끝대(4)의 투출시 조정숫돌바퀴(2)가 지지되는 작동테이블(5)을 구동모터(16)의 회전력에 의해서 회전하는 회전축(11)에 고정된 조정숫돌바퀴(2)의 이동제어캠(13)으로 신속, 정확하게 작동시켜 조정숫돌바퀴(2)를 횡방향으로 이동시켜 줄 수 있고, 상기 회전축(11)에서 이동제어캠(13)과 함께 회전하는 끝대급송제어용캠(14)으로 끝대급송장치(21)의 작동시기를 제어할 수 있도록 한 것이기 때문에 연삭기를 고속으로 운전할 수 있어 생산성 향상을 도모할 수 있음과, 끝대급송장치(21)의 흡퍼(25)로 반제품 상태의 끝대(4)를 투입하는 자동화를 도모할 수 있기 때문에 저렴한 생산비용으로 대량가공할 수 있어 작업능률화를 기할 수 있는 매우 유용한 고안인 것이다.The grinding machine according to the present invention rotates the operation table 5 on which the adjustment wheel 2 is supported by the input of the end 4 as a work piece and the discharge of the processed end 4 by the rotational force of the driving motor 16. It is possible to move the adjustment wheel 2 in the lateral direction by quickly and accurately operating the movement control cam 13 of the adjustment wheel 2 fixed to the rotation shaft 11, and control the movement on the rotation shaft 11. The tip feeding control cam 14 which rotates together with the cam 13 can control the operation timing of the tip feeding device 21, so that the grinding machine can be operated at high speed, and the productivity can be improved. Since the suction device 25 of the feeding device 21 can automate the introduction of the end 4 of the semi-finished state, it can be mass-processed at a low production cost, and thus it is a very useful design that can improve work efficiency.
