Abstract

PURPOSE: A tapping drill for a tapping machine is provided to relieve resistance added to a tapping drill in a tapping task because a tapping drill connector is not horizontally moved and elastically moved within a range of the length of a guide hole only in a vertical direction by an elastic force of a coil spring. CONSTITUTION: A tapping drill for a tapping machine comprises a drill body unit(1), a tapping drill connector(3), a tapping drill(2), and a coil spring(5). A combining groove(1c) is vertically formed in the central lower part of the drill body unit and opened downward. The coil spring is inserted into a combining groove and a head portions of fixing bolts(4,4a) thread-combined to both side walls is assembled in a guide hole(1d) formed in the both side walls of the combining groove after combining the tapping drill connector and the tapping drill connector receiving elasticity of the coil spring moves within a predetermined range and rotates with the drill body and a distance in which the tapping drill connector is vertically moved is controlled so that resistance in a task is relieved.

Description

태핑머신용 태핑드릴{machine tapping for tapping drilling}Machine tapping for tapping drilling

본 발명은 태핑머신용 태핑드릴에 관한 것으로 보다 구체적인 것은, 드릴본체부에 태핑드릴을 착탈하는 태핑드릴결합자를 장치하고, 상기 태핑드릴결합자를 태핑머신의 회전축 하단 결합부에 결합되는 드릴본체부에 결합시켜서 착탈이 용이하고 태핑드릴의 보호가 원만하게 구성한 것이다.
The present invention relates to a tapping drill for a tapping machine, and more specifically, to a drill main body having a tapping drill coupler for attaching and detaching a tapping drill to the drill body portion, the tapping drill coupler being coupled to a lower end coupling portion of a rotating shaft of the tapping machine. It is easy to attach and detach by combining the protection of the tapping drill is configured smoothly.

종래의 태핑드릴은 회전축 하단에 생크를 장치하고 생크하단에 콜릿척을 장착하여 콜릿척 하단부에 조임구를 부착한 다음, 태핑드릴 상단을 콜릿척에 끼워 조임구로 조여서 사용하고 있으나, 태핑작업은 태핑드릴에 가해지는 저항이 일반적인 드릴링 작업보다 현저히 크기 때문에 콜릿척과 태핑드릴의 결합부가 헐거워지므로 수시로 긴장을 시켜야 하는 불편이 있어 작업능률이 떨어지고 이를 방지하기 위해 태핑드릴 전용척을 구입하여 장치하고 있으나, 가격이 많아 부담이 가중되는 불편이 있으며 그럼에도 태핑드릴에 완충기능이 없어 태핑작업시에 일어나는 저항때문에 태핑드릴이 쉽게 부러지는 결점이 있었다.
Conventional tapping drill is equipped with a shank at the bottom of the rotary shaft and a collet chuck at the bottom of the shank to attach a fastener to the bottom of the collet chuck, and then tighten the top of the tapping drill into the collet chuck to tighten the fastener, but the tapping operation Since the resistance to the drill is significantly higher than the general drilling work, the coupling part of the collet chuck and the tapping drill is loose, which makes it difficult to tension frequently, which reduces the work efficiency and purchases a dedicated tapping drill chuck to prevent it. There are many inconveniences that add to the burden and nevertheless there is a defect that the tapping drill is easily broken due to the resistance that occurs during the tapping operation because there is no buffer function.

본 발명은 상기와 같은 불편을 해소할 수 있도록 태핑드릴을 태핑드릴결합자에 결합하고 태핑드릴결합자를 회전축에 결합되는 드릴본체부에 결합하여 태핑드릴본체부를 교환할 수 있게 독립상품화시켜 태핑작업시 태핑드릴의 파손이 방지되어 태핑작업이 안전하고 정밀하며 교환시 가격부담이 적은 이점을 얻도록 만든 것이다.
The present invention combines the tapping drill to the tapping drill combiner to eliminate the inconvenience as described above and the tapping drill combiner coupled to the drill main body coupled to the rotating shaft to replace the tapping drill main body in the case of tapping operation It prevents the tapping drill from being damaged so that the tapping work is safe and precise and the cost is less at the exchange.

본 발명은 상단부에 테이퍼형 결합부가 형성되어 회전축의 테이퍼형 결합홈에 결합되고 하단부에 태핑드릴결합부가 형성된 드릴본체부와 드릴본체부의 태핑드릴결합부에 태핑드릴결합자를 장착하여 결합부에 완충장치를 하고 태핑드릴결합부에 태핑드릴을 결합하여 독립된 상품이 되도록하여 착탈이 편리하고 태핑작업시 태핑드릴에 가해지는 충격의 완충이 용이하게 구성하여 파손율을 줄이고 신규 교환시 가격부담이 적은 이점을 얻을 수 있게 만든 것이다.
According to the present invention, a tapered coupling part is formed at an upper end thereof, and is coupled to a tapered coupling groove of a rotating shaft, and a tapping drill coupling part is mounted to a tapping drill coupling part of a drill main part and a drill main part, in which a tapping drill coupling part is formed at a lower end thereof, and a shock absorber in the coupling part. By combining the tapping drill into the tapping drill coupling part to be an independent product, it is easy to attach and detach and the shock absorbing on the tapping drill during the tapping operation is easily configured to reduce the breakage rate and to reduce the cost burden for new exchange. It is made available.

이와 같이 된 본 발명은 태핑드릴 본체부 하단에 형성된 결합홈에 태핑드릴이 결합된 태핑드릴결합자를 결합시켜서 드릴본체부 상측에 형성된 테이퍼형 결합부를 회전축의 하단에 형성된 테이퍼형 결합홈에 결합하면 드릴본체부의 상단 테이퍼형결합부가 회전축의 하단 테이퍼형 결합홈에 밀착되면서 테이퍼형 결합부 상단에 형성된 각형돌출기가 결합홈의 각형고정홈에 결합되므로 태핑머신의 회전축이 회전하면 드릴본체부가 회전하여 태핑작업이 가능케 된다.The present invention as described above is coupled to the tapered coupling groove formed on the lower end of the rotary shaft by coupling the tapping drill combiner coupled to the tapping drill coupled to the coupling groove formed at the bottom of the tapping drill main body drill As the upper tapered coupling part of the main body part is in close contact with the lower tapered coupling groove of the rotating shaft, the square protrusion formed on the upper part of the tapered coupling part is coupled to the square fixing groove of the coupling groove, so that when the rotary shaft of the tapping machine rotates, the drill body rotates and tapping. This is possible.

특히, 본 발명은 드릴 본체부 하단 중심부에 세로방향으로 하향 개방되게 결합홈을 형성하여 결합홈내에 코일스프링을 넣고 태핑드릴결합자를 결합시킨 후 결합홈 양측벽에 형성된 가이드구멍으로 태핑드릴결합자의 양측벽에 나사조립된 고정볼트 머리 부분이 돌출되어 걸림되게 조립되므로 결합홈내에 삽입되어 코일스프링의 탄력을 받는 태핑드릴결합자가 결합홈에서 상하로 일정범위를 움직이면서 드릴본체와 같이 회전하게 되고, 또한 태핑드릴결합자는 드릴본체부의 결합홈에서 상하로 움직이는 거리가 제한되어 그 범위에내에서 스프링탄력을 받아 탄력작용을 하므로 태핑드릴로 태핑작업을 시작하거나 태핑후 복원될 때, 태핑드릴에 작용하는 저항을 즉시 완화시켜주는 완충작용을 하므로 작업중에 드릴이 파손될 염려가 없도록 되며, 태핑드릴결합자는 태핑드릴본체부의 결합홈에 끼워져서 태핑드릴결합자 양측벽에 나사조립된 고정볼트에 의하여 가이드홈내에서 제어되므로 태핑드릴결합자가 길이방향으로 쿠션작용이 가능하게 결합이 이루어져 좌우로는 흔들리지 않고, 상하방향으로만 코일스프링의 탄력을 받아 탄력을 충진하면서 가이드 구멍의 길이범위에서 탄동되므로 태핑작업시 태핑드릴에 가해지는 저항을 부드럽게 완화시키는 효과를 낼 수 있게 된다.In particular, the present invention forms a coupling groove in the longitudinal center of the lower end of the drill body portion to put the coil spring in the coupling groove and combine the tapping drill combiner, both sides of the tapping drill combiner with guide holes formed on both side walls of the coupling groove. The fixed bolt head screwed on the wall is assembled to protrude and hook, so that the tapping drill joiner inserted into the coupling groove and receiving the elasticity of the coil spring rotates with the drill body while moving a certain range up and down in the coupling groove, and also tapping. Since the drill combiner is limited in the distance moving up and down in the coupling groove of the drill body and receives elasticity within the range, the drill combiner starts the tapping operation with the tapping drill or restores the tapping drill when it is restored after tapping. The cushioning effect is immediately relieved so there is no risk of breakage of the drill during operation. Since the drill combiner is inserted into the coupling groove of the tapping drill body part and is controlled in the guide groove by the fixing bolt screwed to both sides of the tapping drill combiner, the tapping drill combiner is coupled to allow the cushioning action in the longitudinal direction and is shaken from side to side. Instead, the coil spring is elastically filled only by receiving the elasticity of the coil spring in the up and down direction, and thus the elasticity is relieved in the length range of the guide hole, thereby smoothly alleviating the resistance applied to the tapping drill during the tapping operation.

그리고 본 발명은 드릴본체부와 태핑드릴을 하나의 구성체로 조립하여 단독상품으로 거래할 수 있도록 간결하게 구성되어 가격을 저렴하게 만들어 공급할 수 있으므로 사용자가 신규구입을 할때 비용부담을 덜어주는 이점을 얻을 수 있는 장점이 있다.
In addition, the present invention has the advantage of reducing the cost burden when the user purchases a new product because it can be supplied by making the drill body and the tapping drill as a single component to be compactly configured to trade as a single product at a low price There is an advantage that can be obtained.
