본 고안은 공작기계용 U형 클램프에 관한 것으로 특히 클램프가 필요로 하는 강도를 유지하면서도 자중이 상대적으로 적게 나가 취급이 용이하고 안전한 공작기계용 U형 클램프에 관한 것이다.The present invention relates to a U-shaped clamp for machine tools, and more particularly, to a U-shaped clamp for machine tools that maintains the strength required by the clamp and is relatively easy to handle and safe.

종래 공작기계의 베이스에 공작물을 클램핑시키는 수단은, 중앙에 끼움부에 길게 형성된 U형 클램프와, 베이스의 홈부에 끼워지는 머리가 형성되어 상기 끼움부를 관통되게 끼워지는 볼트와, 상기 볼트에 체결되는 너트로 구성되어 있다.Means for clamping the workpiece to the base of the conventional machine tool, the U-shaped clamp is formed in the center of the fitting long, the head is formed in the groove of the base is formed, the bolt is inserted through the fitting portion, and fastened to the bolt It consists of a nut.

그러나 공작물 클램핑 수단으로 사용되는 종래의 클램프는, 가공시 공작물에 가해지는 힘에 의해 클램핑 상태가 변동되지 않아야 하기 때문에, 큰 클램핑력에 대하여 견딜 수 있는 강도를 가져야하므로 자중이 많이 나가 작업자가 운반 및 취급하는데 어려움이 따르게 될 뿐만 아니라 취급중 떨어뜨리게 되면 부상의 위험이 큰 문제점이 있었다.However, the conventional clamp used as the work clamping means should have a strength that can withstand a large clamping force because the clamping state should not be changed by the force applied to the work piece at the time of machining. In addition to the difficulty of handling, if dropped during handling there was a big risk of injury.

본 고안은 이와같은 점을 감안하여 안출한 것으로서 공작물과 닿지않는 클램프의 내외측면에 홈을 길게 형성하고 볼트가 통과하는 끼움부의 중앙후방에 보강부를 가로지르게 일체로 형성함으로서 클램프가 필요로 하는 강도를 유지하면서도 자중이 상대적으로 적게 나가 취급이 용이하고 안전한 공작기계용 U형 클램프를 제공하기 위한 것이다.The present invention has been devised in view of the above, and the grooves are formed on the inner and outer sides of the clamp that do not come into contact with the workpiece, and the strength required by the clamp is formed by integrally forming the reinforcement part across the center rear portion of the fitting through which the bolt passes. Its purpose is to provide a U-shaped clamp for machine tools that is easy to handle and safe due to its relatively low weight.

이하 본 고안의 바람직한 실시예를 첨부 도면에 의거 상세히 설명하며 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 제1도 및 제2도에 도시된 바와같이 중앙에 끼움부(11)가 길게 형성된 U형 클램프(10)와, 베이스(40)의 홈부(41)에 끼워지는 머리(21)가 형성되어 상기 끼움부(11)에 관통되게 끼워지는 볼트(20)와, 상기 볼트(20)에 체결되는 너트(30)로 구성된 클램핑 장치에 있어서, 상기 U형 클램프(10)의 내외측면에 홈(12)을 횡으로 길게 형성하고, 끼움부(11)의 중앙 후방에 보강부(13)를 가로지르게 일체로 형성하여서 된 것이다.According to the present invention, as shown in FIGS. 1 and 2, the U-shaped clamp 10 having a long fitting portion 11 formed at the center thereof and a head 21 fitted to the groove portion 41 of the base 40 are provided. In the clamping device formed of a bolt 20 formed to penetrate the fitting portion 11 and the nut 30 fastened to the bolt 20, grooves in the inner and outer sides of the U-shaped clamp 10 (12) is formed long horizontally, and integrally formed across the reinforcement part 13 in the center back of the fitting part 11. As shown in FIG.

이와같이 된 본 고안의 클램핑 장치는 공작기계 베이스(40)의 홈부(41)에 볼트(20)의 머리(21)를 끼워넣고, 끼움부(11)를 통해 볼트(20)에 U형 클램프(10)를 끼워 공작물을 눌러줄 수 있게 한 상태가 되게 한후 너트(30)를 볼트(20)에 나착하여 조여주게 되면 제3도에 도시된 바와 같이 U형 클램프(10)가 공작물을 베이스(40)에 견고히 클램핑하게 된다.In this way, the clamping device of the present invention inserts the head 21 of the bolt 20 into the groove portion 41 of the machine tool base 40, and the U-shaped clamp 10 to the bolt 20 through the fitting portion 11. After inserting the) into a state that can press the workpiece 30 and then tighten the nut 30 to the bolt 20, the U-shaped clamp 10 as shown in Figure 3 the base 40 to the workpiece It is clamped firmly at.

클램핑된 공작물을 꺼내려고 할 경우에는 너트(30)를 약간 풀어주면 된다.If you want to take out the clamped workpiece, loosen the nut 30 slightly.

이렇게 공작물을 베이스(40) 상에 클램핑해주는 U형 클램프(10)는 공작물이 가공될 때 공작물에 가해지는 힘에 의해 클램핑 상태가 변동되지 않아야 하기 때문에 큰 클램핑력에 대하여 견딜 수 있는 강도를 가져야 하는 것으로 본 고안에 있어서 내외측면에 횡으로 길게 형성된 홈(12)에 의해 작아진 U형 클램프(10)의 강도는 끼움부(11)를 가로지르는 보강부(13)에 의하여 보상받는다. 즉 보강부(13)는 U형 클램프(10)가 충분한 강도를 유지할 수 있게 하는 역할을 한다.Thus, the U-shaped clamp 10 clamping the workpiece on the base 40 has a strength that can withstand a large clamping force because the clamping state should not be changed by the force applied to the workpiece when the workpiece is processed. In the present invention, the strength of the U-shaped clamp 10 reduced by the groove 12 formed laterally on the inner and outer sides is compensated by the reinforcing portion 13 across the fitting portion 11. In other words, the reinforcement 13 serves to maintain the U-type clamp 10 sufficient strength.

보강부(13)에 의해 충분한 강도를 갖는 본 고안의 U형 클램프(10)는 홈(12)에 해당되는 만큼 종래의 것에 비하여 가벼운 것으로 U형 클램프(10)의 무게가 가볍다는 것은 운반 및 취급이 용이한 동시에 떨어뜨렸을 때 큰 부상을 입지 않게 된다는 것을 의미한다.The U-shaped clamp 10 of the present invention having sufficient strength by the reinforcing portion 13 is lighter than the conventional one as it corresponds to the groove 12, and the weight of the U-shaped clamp 10 is light and transported. This means that you will not suffer any serious injuries when dropped.

한편 볼트(20)가 보강부(13) 위치를 통과하여 공작물을 클램핑 해야 하는 경우에는 U형 클램프(10)를 180°돌려놓고 클램핑 작업하게 되면 보강부(13)가 중앙에서 약간 후방으로 형성되어 있기 때문에 볼트(20)가 끼움부(11)를 통과하는데 지장을 초래하지 않게 된다.On the other hand, when the bolt 20 has to pass through the reinforcement portion 13 to clamp the workpiece, when the U-shaped clamp 10 is turned 180 ° and the clamping operation is performed, the reinforcement portion 13 is formed slightly rearward from the center. Since the bolt 20 passes through the fitting portion 11 will not cause any trouble.

이와같이 본 고안은 공작물과 닿지 않는 U형 클램프(10)의 내외측면에 홈(12)을 길게 형성하고 볼트(20)가 통과하는 끼움부(11)의 중앙 후방에 보강부(13)를 가로지르게 일체로 형성함으로서 U형 클램프(10)가 필요로 하는 강도를 유지하면서도 자중이 상대적으로 적게 나가 취급이 용이하고 안전한 공작기계용 U형 클램프에 관한 것이다.In this way, the present invention forms a long groove 12 on the inner and outer sides of the U-shaped clamp 10 that does not come into contact with the workpiece and crosses the reinforcement 13 at the center rear of the fitting portion 11 through which the bolt 20 passes. The present invention relates to a U-type clamp for a machine tool which is easy to handle and maintains its own weight while maintaining the strength that the U-type clamp 10 requires.
