본 고안은 각종 공작대로 사용되는 회전테이블의 록크장치에 관한 것이다.The present invention relates to a lock device of a rotary table used for various work benches.
종래 이런 종류의 록크장치로서는 제4도에 도시한 바와 같이, 베이스(11)에 고정된 공압실린더(미도시)의 피스톤롯드(12)를 회전테이블(13)의 록크공(14)에 직접 삽입토록 되어 있으며 롯드(12)는 록크공(14)이 일치되기 직전부터 돌출되는 것이므로 롯드(12)가 록크공(14)에 삽입시 테이블(13)과의 마찰력에 의해 롯드(12)가 회전방향으로 밀려서 휘어지므로 차후 록크작용이 불가능하게 되며 공압실린더 전체를 훼손시키는 폐단있었다.As a conventional locking device of this kind, as shown in FIG. 4, a piston rod 12 of a pneumatic cylinder (not shown) fixed to the base 11 is directly inserted into the lock hole 14 of the rotary table 13. Since the rod 12 is projected from just before the lock ball 14 is matched, the rod 12 is rotated by the friction force with the table 13 when the rod 12 is inserted into the lock ball 14. As it was pushed into the rod, it was impossible to lock in the future, and there was an end to damage the entire pneumatic cylinder.
따라서 본 고안은 이러한 종래의 폐단을 해소하기 위하여 안출된 것으로 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve such a conventional discontinuity and described in detail according to the accompanying drawings as follows.
제1도 내지 제3도에 도시한 바와 같이, 베이스(1)의 일측에 공압실린더(2)를 그 피스톤롯드(3)가 상부로 돌출되게 착설하고, 베이스 상면에는 피스톤롯드(3)를 외감하는 케이싱(4)을 착설하며, 롯드(3)의 선단부에는 걸림턱(5')이 형성된 캡(5)을 나착하여 케이싱(4)의 통공(4')을 통해 상하로 출몰가능하게 설치하여서 된 것이다.As shown in FIGS. 1 to 3, the pneumatic cylinder 2 is installed on one side of the base 1 so that the piston rod 3 protrudes upward, and the piston rod 3 is externally wound on the base upper surface. The casing 4 is installed, and the cap 5 having the locking jaw 5 'is attached to the tip of the rod 3 so that the casing 4 can be mounted up and down through the through hole 4' of the casing 4. It is.
상기 공압실린더(2)는 피스톤(3')에 마그네트(M)를 감착하고, 실린더 외주상하에는 마그네트(M)에 의해 작동되는 근접스위치(SW1)(SW2)를 착설하여 공압실린더(2)의 압축공기유로를 전환하는 솔레노이드 밸브(SV)를 제어토록 한 것을 사용한다.The pneumatic cylinder (2) attaches the magnet (M) to the piston (3 '), and installs the proximity switch (SW1) (SW2) operated by the magnet (M) on the upper and lower cylinder periphery of the pneumatic cylinder (2) Use the solenoid valve (SV) to control the compressed air flow.
미설명부호(6)은 베이스(1)상에 설치된 지지로울러(7)에 의해 지지되는 회전테이블이고, (8)은 테이블에 천설된 록크공이며 (9)는 베이스에 착설된 정지판이고, (10)(10')은 테이블(6)에 설치된 정지도그이고 (LS)(LS1)는 리이트 스위치이다.Reference numeral 6 is a rotary table supported by a support roller 7 installed on the base 1, 8 is a lock ball installed in the table and 9 is a stop plate mounted on the base, (10) and 10 'are stationary dogs provided in the table 6, and (LS) and LS1 are limit switches.
이러한 구성의 본 고안은 회전테이블(6)을 베이스(1)의 지지로울러(7)상에서 회전시켜 도그(10) 또는 (10')가 리미트 스위치(LS) 또는 (LS1)를 동작시키면, 솔레노이드밸브(SV)를 피스톤롯드(3)가 돌출되는 상태로 동작시킴과 동시에 회전테이블(6)을 구동하는 모우터(미도시)를 서서히 감속시킨다. 피스톤롯드(3)가 돌출되면 테이블(6)의 록크공(8)에 캡(5)이 삽입되어 테이블(6)은 록크된다.The present invention of such a configuration has a solenoid valve when the rotary table 6 is rotated on the support roller 7 of the base 1 so that the dog 10 or 10 'operates the limit switch LS or LS1. While operating the SV in a state where the piston rod 3 protrudes, the motor (not shown) that drives the rotary table 6 is gradually decelerated. When the piston rod 3 protrudes, the cap 5 is inserted into the lock hole 8 of the table 6 so that the table 6 is locked.
여기서 상기 공압실린더(2)의 피스톤롯드(3)는 록크공(8)이 캡(5)선단에 일치하는 위치까지 회전되기 직전부터 돌출되며 테이블(6)이 감속회전되어 록크공(8)이 캡(5)선단 위치에 이르면 캡(5)은 록크공(8)에 삽입되어 록크하게 된다.Here, the piston rod 3 of the pneumatic cylinder 2 protrudes from just before the lock ball 8 is rotated to a position corresponding to the tip of the cap 5, and the table 6 is decelerated and rotated so that the lock ball 8 is rotated. When the tip of the cap 5 is reached, the cap 5 is inserted into the lock hole 8 to be locked.
따라서 캡(5)이 록크공(8)에 삽입되기 직전에는 캡(5)선단이 테이블(6)의 저면과 마찰접촉하여 회전방향으로의 굽힘력이 피스톤롯드(3)에 걸리는 상태가 되는데, 피스톤롯드(3)의 선단에 나착된 캡(5)이 케이싱(4)의 통공(4')에 의해 측방으로 지지되므로 피스톤롯드(3)에는 굽힘력이 전달되지 않게 된다.Therefore, just before the cap 5 is inserted into the lock hole 8, the tip of the cap 5 is in frictional contact with the bottom surface of the table 6 such that bending force in the rotational direction is applied to the piston rod 3, Since the cap 5 attached to the front end of the piston rod 3 is supported laterally by the through hole 4 ′ of the casing 4, no bending force is transmitted to the piston rod 3.
이상과 같이 본 고안에 의하면 공압실린더의 피스톤롯드가 테이블의 록크공에 직접 삽입되지 않고 그 선달에 캡을 나착하여 케이싱의 통공에 의해 측방으로 지지토록 하였으므로 회전테이블의 록크작동시 피스톤롯드가 휘어지는 일이 없게 되어 상시 정상작동상태를 유지할 수 있으며 공압실린더의 수명을 연장시킬 수 있는 효과가 있다.As described above, according to the present invention, the piston rod of the pneumatic cylinder is not directly inserted into the lock hole of the table, but the cap is attached to the front end of the pneumatic cylinder so that the piston rod is laterally supported by the through hole of the casing. This eliminates the need to maintain normal operating conditions and extend the life of pneumatic cylinders.
