Description

드릴 천공깊이 조절장치Drill depth adjustment device

본 발명은 드릴 천공깊이 조절장치에 관한 것으로서, 특히 드릴비트에 물려 고정되어 걸림턱 역할을 함으로써 드릴비트가 피가공체의 원하는 깊이까지만 뚫고 들어가고 더 이상은 들어가지 않도록 하는 드릴 천공깊이 조절장치에 관한 것이다. The present invention relates to a drill drilling depth adjusting device, and more particularly, to a drill drilling depth adjusting device to be drilled into only the desired depth of the workpiece, so that the drill bit only penetrates to the desired depth of the workpiece by being fixed to the drill bit to serve as a locking jaw will be.

피가공체에 소정 깊이의 드릴 홀을 형성시키고자 할 때에 드릴비트의 삽입깊이를 제어할 특별한 수단이 없다면 오로지 작업자의 주의력에 의존할 수밖에 없게 되고, 따라서 작업자의 실수로 인하여 드릴 홀이 원하는 깊이 이상으로 형성되어 버리거나 피가공체가 아예 관통되어 버리는 문제가 많이 발생한다. If there is no special means to control the insertion depth of the drill bit when forming a drill hole having a predetermined depth in the workpiece, only the operator's attention can be relied on. It is formed as a problem or a lot of problems that the workpiece is penetrated at all.

이와 같은 문제점을 해소하기 위하여 드릴에 별도의 눈금자를 설치하여 드릴비트의 삽입깊이를 제어하고 있다. 그러나 이 경우 필요시마다 눈금자를 드릴몸체에 결합시키거나 해체해야 하는 번거로움이 있고, 해체 시에는 분리되어 있는 눈금자를 별도로 보관하고 있어야 하는 번거로움이 있다. 즉, 눈금자의 분실 위험과 보관을 위한 수납공간이 확보가 요구되는 단점이 있다는 것이다. 뿐만 아니라 눈금자가 드릴비트에 바로 붙어 있는 것이 아니라 어느 정도 이격되도록 결합되어야 하기 때문에 드릴 홀의 깊이에 오차가 발생되기 쉽다는 단점이 있다.In order to solve this problem, a separate ruler is installed on the drill to control the insertion depth of the drill bit. However, in this case, when necessary, there is a need to combine or disassemble the ruler to the drill body, and when dismantling, there is a need to separately store the ruler. That is, there is a disadvantage that the risk of losing the ruler and the storage space for storage is required. In addition, there is a disadvantage in that an error is likely to occur in the depth of the drill hole because the ruler is not attached directly to the drill bit but must be coupled to a certain distance.

따라서 본 발명이 해결하고자 하는 과제는, 드릴비트가 원하는 깊이 이상으로는 더 이상 삽입되어 들어가지 않도록 할 뿐만 아니라 드릴 작업 이후에도 드릴비트에 끼워진 채로 함께 보관될 수 있도록 하여 분실을 방지할 수 있으며, 드릴비트에 직접 체결됨으로써 드릴 홀의 깊이에 오차가 발생하는 것을 방지할 수 있는 드릴 천공깊이 조절장치를 제공하는 데 있다.

As shown in FIG. 6, the slide key 170 may have a rod shape, for example, a square rod shape, and the drill bit 10 is interviewed with the drill bit 10 when it is pushed outwardly to the outside of the slide groove 112. It is preferable to be installed to bite.

이를 위하여 드릴비트(10)에 닿는 슬라이드키(170)의 끝단부에는 테이퍼링면(173)이 형성되는 것이 바람직하다. 테이퍼링면(173)은 드릴비트(10)의 축 방향과 나란하게 형성되는 것이 바람직하다. 또한 슬라이드키(170)와 드릴비트(10)가 서로 미끄러지지 않도록 테이퍼링면(173)에는 미끄럼 방지를 위한 요철부(171)가 형성되는 것이 바람직하다. For this purpose, it is preferable that the tapering surface 173 is formed at the end of the slide key 170 which contacts the drill bit 10. The tapering surface 173 is preferably formed in parallel with the axial direction of the drill bit 10. In addition, it is preferable that the uneven portion 171 for preventing slipping is formed on the tapering surface 173 so that the slide key 170 and the drill bit 10 do not slip together.

도 7 및 도 8은 본 발명에 따른 드릴 천공깊이 조절장치(100)의 동작원리를 설명하기 위한 도면들이다. 7 and 8 are views for explaining the principle of operation of the drill hole depth adjustment apparatus 100 according to the present invention.

도 7 및 도 8에 도시된 바와 같이, 작업자가 회전축(151)의 손잡이(153)를 잡고 회전축(151)을 돌리면 그로 인해 회전조절나사가(150)가 회전하게 되고, 이 때 회전조절나사(150)의 나사산(152)과 회전몸체(120)의 나사산(123)이 맞물려 있으므로 회전몸체(120)가 따라서 회전하게 된다. 그러면 회전몸체(120)의 회전방향에 따라 슬라이드키(170)가 슬라이드홈(112)을 따라 슬라이딩하여 슬라이드홈(112)의 바깥으로 밀려나오거나 안으로 밀려들어가게 된다. As shown in Figure 7 and 8, when the operator grasps the handle 153 of the rotating shaft 151 and rotates the rotating shaft 151, the rotation adjusting screw 150 is rotated thereby, the rotation adjusting screw ( Since the thread 152 of the 150 and the thread 123 of the rotating body 120 are engaged, the rotating body 120 rotates accordingly. Then, the slide key 170 slides along the slide groove 112 in accordance with the rotation direction of the rotary body 120 to be pushed out of the slide groove 112 or pushed in.

슬라이드홈(112)이 테이퍼부(111a)에 형성되어 있기 때문에 슬라이드키(170)가 슬라이드홈(112)의 바깥으로 밀려나올 때에는 드릴비트(10)를 무는 방향으로 경사지게 밀려나온다. 따라서 본 발명에 따른 드릴 천공깊이 조절장치(100)는 슬라이드키(170)에 의해 드릴비트(10)의 원하는 위치에 물려 고정되며, 이 때 드릴비트(10)의 어느 위치에 고정되느냐에 따라 천공깊이가 정해진다. Since the slide groove 112 is formed in the tapered portion 111a, when the slide key 170 is pushed out of the slide groove 112, the slide bit 112 is pushed out obliquely in the direction of biting the drill bit 10. Therefore, the drill drilling depth adjusting device 100 according to the present invention is fixed to the desired position of the drill bit 10 by the slide key 170, at this time perforation depending on which position of the drill bit 10 is fixed Depth is determined.

상기 회전조절나사(150)가 설치되지 않는 경우에는 작업자가 회전몸체(120)를 직접 손으로 잡고 돌리면 될 것이다. When the rotation adjustment screw 150 is not installed, the operator may turn by holding the rotation body 120 by hand.

천공깊이는 피가공체 보호링(140)이 피가공체(20)의 표면에 닿을 때까지 드릴비트(10)가 피가공체(20)에 삽입되어 들어감으로써 제한된다. 이 때, 피가공체 보호링(140)은 베어링(130)에 의해 고정몸체(110)와 겉돌기 때문에 드릴비트(10)가 회전하더라도 피가공체(20)에 면접된 상태로 가만히 있게 되어 피가공체(20)의 표면이 손상되지 않고 보호된다. The drilling depth is limited by the drill bit 10 being inserted into the workpiece 20 until the workpiece protection ring 140 touches the surface of the workpiece 20. At this time, the workpiece protection ring 140 is rotated with the fixed body 110 by the bearing 130, so that even if the drill bit 10 is rotated to remain in the interviewed state to the workpiece 20 The surface of the workpiece 20 is protected without being damaged.

상술한 바와 같이 본 발명에 의하면, 천공 시 드릴 천공깊이 조절장치(100)가 걸림턱 역할을 하기 때문에 드릴비트(10)가 원하는 깊이 이상으로는 더 이상 삽입되어 들어가지 않게 된다. 따라서 드릴 천공깊이 조절장치(100)를 드릴비트(10)의 원하는 위치에 설치함으로써 천공깊이를 손쉽게 제한할 수 있다. As described above, according to the present invention, since the drill drilling depth adjusting device 100 serves as a locking jaw during drilling, the drill bit 10 is no longer inserted into the desired depth. Therefore, it is possible to easily limit the drilling depth by installing the drill drilling depth adjusting device 100 at a desired position of the drill bit 10.

또한, 드릴 작업 이후 드릴 천공깊이 조절장치(100)를 드릴비트(10)에 끼워진 채로 함께 보관할 수 있으므로 드릴 천공깊이 조절장치(100)의 분실을 방지할 수 있다. 그리고 드릴 천공깊이 조절장치(100)가 드릴비트(10)에 직접 체결되어 걸림턱 역할을 하기 때문에 천공깊이에 오차가 발생하는 것을 방지할 수 있다.In addition, since the drill drilling depth adjusting device 100 may be stored together while being inserted into the drill bit 10 after the drilling operation, the loss of the drilling drilling depth adjusting device 100 may be prevented. In addition, since the drill drilling depth adjusting device 100 directly engages the drill bit 10 to serve as a locking step, an error may be prevented from occurring in the drilling depth.
