본 고안은 불균형 비대칭 공작물 가공을 위한 특수척에 대한 것으로서, 특히 자동차 부품인 마스터 실린더등과 같이 주물원통면을 기준으로 해서 길이방향으로 지름의 치수변화가 있는 공작물을 보다 견고히 척킹할 수 있도록 된 것이다.The present invention is for a special chuck for unbalanced asymmetric workpiece processing, and particularly, it is possible to firmly chuck a workpiece with a dimensional change in diameter in the longitudinal direction based on a casting cylindrical surface such as a master cylinder, which is an automobile part. .

일반적인 척은 제 1 도에서 보는 바와 같이 마스터 죠오(1)와 드로우플랜지(2)가 서로 경사형 옷지(3)로 끼워져 연결되므로 드로우바(4)의 진퇴작동에 의해 소프트 죠오(5)가 상하로 슬라이딩 될 수 있게 되어있었다.As shown in FIG. 1, the general jaw is connected to the master jaw (1) and the draw flange (2) by the inclined cloth (3), so that the soft jaw (5) is moved up and down by the retraction operation of the draw bar (4). It was supposed to be sliding.

그러나 이러한 죠오로는 길이방향으로 각기 지름이 다른 공작물을 척킹하게 되면 죠오의 물림면이 축방향으로 나란한 면이기 때문에 지름이 작은 쪽은 지지력을 받지 못하게 된다.However, when the jaws are chucked to workpieces with different diameters in the longitudinal direction, the jaws of the jaws are parallel to each other in the axial direction, so that the smaller diameters are not supported.

따라서 종래에는 죠오의 물림면을 불규칙적인 공작물의 모양대로 사전에 깍아 맞춘후 척킹을 하거나 또는 공작물의 높은지름 일부를 깍아내고 척킹 하므로서 많은 불량품이 나오고 또한 작업시간이 많이 소요되는 결점이 있었다.Therefore, in the related art, the bite surface of the jaw is chamfered in advance in the shape of an irregular workpiece and then chucked or by cutting off and chucking a part of the high diameter of the workpiece, so that many defects come out and the work takes a long time.

본 고안은 이와 같은 종래의 결점을 시정보완하기 위해 안출한 것으로서 이를 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional defect as described in detail by the accompanying drawings as follows.

척아답터(12)와 본체(11)가 결합된 사이 공간(13)내에서 드로우바(14)에 의해 좌우 진퇴되는 죠인트(15)의 외연에 작동구(16)를 결합하여 본체(11)의 상단내에서 좌우 슬라이딩 되는 앵글바(17)와 연결한다.In the space 13 between the chuck adapter 12 and the main body 11, the operating tool 16 is coupled to the outer edge of the joint 15 left and right retracted by the draw bar 14 of the main body 11. It connects with the angle bar 17 which is slid left and right within the top.

물단하부에 경사면을 갖는 앵글바(17)는 클램프 죠인트(18)의 경사홈(19)에 삽입되도록 하고 본체(11)의 상부에 수직으로 끼워진 클램프죠인트(18)의 상단에는 로크너트(20)로 고정된 캡(21)저면에 스프링(22)을 삽입하여 항상 위로 탄지되도록 하고 하단에는 핀(23)으로서 클램프(24)를 가로로 회동고정하며 그 하부에는 V블럭(25)을 볼트(26)로 고정하여서 된 것이다.An angle bar 17 having an inclined surface under the water end is inserted into the inclined groove 19 of the clamp joint 18, and the lock nut 20 is disposed on the upper end of the clamp joint 18 vertically inserted into the upper portion of the main body 11. The spring 22 is inserted into the bottom of the cap 21 fixed with the bolt 21 so as to be always supported upward, and the clamp 24 is rotated horizontally as the pin 23 at the bottom, and the V block 25 is bolted at the bottom thereof. It is fixed by).

도면중 미설명부호 27은 공작물이고 28은 부시이다.In the figure, reference numeral 27 is a workpiece and 28 is a bush.

이와같이 본 고안은 불균형 비대칭 공작물(27)을 척킹하고자 할 때는 본체(11)하단에 계산된 치수의 V블럭(25)을 볼트(26)으로 고정시킨후 공작물(27)을 얹고 드로우바(14)를 전진시키면 제 3 도에서와 같이 조인트(15)와 함께 작동구(16)가 전진하여 앵글바(17)의 하부경사면으로 하여금 클램프 조인트(18)의 경사홈(19)을 밀어내려 그 하부에 핀(23)으로 회동고정된 클램프(24)가 공작물(27)을 클램핑하는 것이다.Thus, when the chucking the unbalanced asymmetric workpiece 27 is fixed, the V block 25 having the calculated dimension is fixed to the bottom of the main body 11 with the bolt 26, and then the workpiece 27 is placed and the draw bar 14 is fixed. As shown in FIG. 3, as shown in FIG. 3, the operating tool 16 moves forward together with the joint 15, causing the lower inclined surface of the angle bar 17 to push down the inclined groove 19 of the clamp joint 18 to the lower portion thereof. The clamp 24 pivoted to the pin 23 clamps the workpiece 27.

이때 공작물(27)의 지름이 길이에 따라 각기 다르더라도 제 2 도 및 제 3 도에서 보는 바와 같이 클램프(24)가 공작물 길이방향으로 회동가능하기 때문에 지름차이에 관계없이 균일한 힘으로 클램핑하게 된다.At this time, even if the diameter of the workpiece 27 is different depending on the length, as shown in FIGS. 2 and 3, the clamp 24 can be rotated in the longitudinal direction of the workpiece, thereby clamping with a uniform force regardless of the diameter difference. .

다시 언클램핑하고자 드로우바(14)를 후퇴시키면 죠인트(15), 작동구(16), 앵글바(17)가 모두 후퇴하므로 클램프 죠인트(18)는 상단의 캡(21) 저면에 탄지된 스프링(22)에 의해 상부로 올라가 언클램핑되는 것이다.When the draw bar 14 is retracted to unclamp again, the joint 15, the actuator 16, and the angle bar 17 are all retracted, so the clamp joint 18 has a spring supported on the bottom of the cap 21 at the top. 22) the upper part is unclamped.

이와같은 본 고안은 앵글바(17)와 경사홈(19)에 의해 클램핑되고 스프링(22)에 의해 언클램핑 되면서 클램핑시에 회동가능토록 핀(23)으로서 가로로 고정된 클램프(24)에 의해 불균형 비대칭 공작물(27)의 지름차이에 관계없이 균일한 힘으로 클램핑할 수 있는 것으로 종래와 같이 죠오의 물림면을 불규칙적인 공작물의 외형에 따라 사전에 깍아 낸후 척킹한다거나 공작물을 깍아내고 척킹하는 등의 작업을 하지 않아도 되므로 작업시간 단축 및 작업성 향상에 발전을 주는 유용한 고안인 것이다.This invention is clamped by an angle bar 17 and an inclined groove 19 and unclamped by a spring 22 and by means of a clamp 24 fixed horizontally as a pin 23 so as to be rotatable during clamping. It is possible to clamp with a uniform force regardless of the diameter difference of the unbalanced asymmetric workpiece 27. As in the prior art, the jaws of the jaws are chamfered in advance according to the irregular shape of the workpiece and chucked, or the workpiece is chucked and chucked. Since it does not need to work, it is a useful design that advances in reducing work time and improving workability.
