본 발명은 일반산업기계의 공작물(workpiece)에 고속 및 고정밀도의 탭가공을 행할 수 있는 탭핑머신용 마스터 스핀들에 관한 것으로서, 보다 상세하게는 척지지부재가 일체로 형성되고, 척지지부재의 하단에 우산형태의 칩커버가 배치되고,상기 척지지부재에 탭의 분리를 용이하게 하는 탭분리용 구멍이 형성되고, 스핀들 볼트에 체결된 부싱너트에 탭핑구멍이 형성되는 탭핑머신용 마스터 스핀들에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a master spindle for a tapping machine capable of high speed and high precision tapping on a workpiece of a general industrial machine. More specifically, the chuck support member is integrally formed, and the lower end of the chuck support member. A chip cover in the form of an umbrella is disposed on the chuck support member, and a tab separating hole is formed in the chuck support member to facilitate separation of the tab, and a tapping hole is formed in a bushing nut fastened to the spindle bolt. will be.

도 1을 참조하면, 종래의 탭핑머신용 마스터 스핀들(1)은 탭공구(3)가 척(5)에 착탈 가능하게 장착되고, 상기 척(5)이 상부 척지지부재(7)에 장착되고, 상기 상부 척지지부재(7)가 하부 지지부재(9)에 착탈가능하게 체결되고, 상기 하부 지지부재(9)가 스핀들 볼트(11)에 장착되고, 상기 스핀들 볼트(11)에 체결되어 하부 지지부재(9)의 하부에 부싱너트(13)가 배치되므로서, 상기 스핀들 볼트(11)가 지그(15)에 고정된 부싱너트(13)에 대해 상대 회전하면서 승하강되고, 상기 스핀들 볼트(11)의 하단부가 유니버설 조인트(또는 "케이블"이라고 함, 도시하지 않음)에 연결되어 동력을 전달받는다.Referring to FIG. 1, a conventional master spindle 1 for a tapping machine is detachably mounted with a tapping tool 3 on a chuck 5, and the chuck 5 is mounted on an upper chuck supporting member 7. The upper chuck support member 7 is detachably fastened to the lower support member 9, the lower support member 9 is mounted to the spindle bolt 11, and the lower support member 9 is fastened to the spindle bolt 11 so as to be lowered. Since the bushing nut 13 is disposed below the support member 9, the spindle bolt 11 is lowered while being rotated relative to the bushing nut 13 fixed to the jig 15, and the spindle bolt ( The lower end of 11 is connected to a universal joint (or "cable", not shown) to receive power.

그러나, 상기와 같은 종래의 탭핑머신용 마스터 스핀들(1)은 스핀들 볼트(11)가 파손될 경우, 하부 지지부재(9)와 스핀들 볼트(11)만을 교체할 수 있도록 상부 척지지부재(7)와 하부 지지부재(9)가 볼팅 방식으로 연결되기 때문에 동심도 불일치 문제가 항상 대두되었으며, 상부 척지지부재(7)와 하부 지지부재(9)가 볼팅 체결방식으로 되어 있기 때문에, 상부 척지지부재(7)와 하부 지지부재(9)의 그 전체길이(h)가 길 수 밖에 없어 공작물을 탭핑가공할 때 탭공구의 흔들림이 큰 문제점이 있었다.However, the conventional master spindle 1 for the tapping machine as described above has an upper chuck support member 7 so that when the spindle bolt 11 is broken, only the lower support member 9 and the spindle bolt 11 can be replaced. Since the lower support member 9 is connected in a bolting manner, a concentricity mismatch problem has always arisen, and since the upper chuck support member 7 and the lower support member 9 are bolted in a fastening manner, the upper chuck support member 7 ) And the entire length (h) of the lower support member (9) is long, so there was a big problem of shaking of the tap tool when tapping the workpiece.

또한, 상기 탭핑머신용 마스터 스핀들(1)은, 도 2에 도시된 바와같이, 버티컬 타입으로 탭가공을 수행할 때 작은 입자의 칩 브레이크(17)가 척(5)으로 유입되므로서, 탭공구(3)가 칩 브레이크(17)에 의해 척(5)에서 빠지지 않을 수 있으며, 버티컬 타입으로 탭가공을 수행할 때, 작은 입자의 칩 브레이크(17)가 부싱 너트(13)와 스핀들 볼트(11) 사이로 들어가 스핀들 볼트(11)와 부싱너트(13)의 나선이 파손될 수 있는 단점이 있다.In addition, as shown in Figure 2, the master spindle 1 for the tapping machine, as the chip break 17 of the small particles are introduced into the chuck 5 when performing the tapping in the vertical type, tapping tool (3) may not be pulled out of the chuck (5) by the chip brake (17), and when performing the tapping in the vertical type, the small particle chip brake (17) causes the bushing nut (13) and the spindle bolt (11). ), The spiral of the spindle bolt 11 and the bushing nut 13 may be broken.

그리고, 종래의 탭핑머신용 마스터 스핀들(1)은, 도 3에 도시된 바와같이, 부싱 너트(13)의 날개부(13a)에 2개의 장착구멍(13b) 만이 형성되어, 도 2에 도시된 것처럼 지그(15)가 언제나 부싱 너트(13)의 날개부(13a) 하부에 배치되어야 하며, 지그(15)가 부싱 너트(13)의 날개부(13a) 상부에 배치되어야 하는 경우에는 부싱 너트(15)를 지그(15)에 고정할 수 없어 작업불능이 발생하는 단점이 있었다.And, in the conventional master spindle 1 for the tapping machine, as shown in FIG. 3, only two mounting holes 13b are formed in the wing portion 13a of the bushing nut 13, and as shown in FIG. As shown, the jig 15 should always be placed under the wing 13a of the bushing nut 13, and if the jig 15 should be placed above the wing 13a of the bushing nut 13, the bushing nut ( 15) can not be fixed to the jig (15) had a disadvantage that the work impossible occurs.

따라서, 본 발명의 목적은 척이 장착되는 척지지부재가 일체로 형성되어, 척지지부재의 길이를 축소할 수 있고, 동심도가 불일치 문제를 해결할 수 있는 탭핑머신용 마스터 스핀들을 제공하는 것이다.Accordingly, an object of the present invention is to provide a master spindle for a tapping machine in which the chuck support member on which the chuck is mounted is integrally formed, which can reduce the length of the chuck support member and solve the problem of inconsistency.

본 발명의 다른 목적은 척지지부재의 하단에 우산형태의 칩커버가 배치되어, 부싱 너트와 스핀들 볼트 사이로 작은 입자의 칩 브레이크가 들어가는 것을 방지하므로서, 스핀들 볼트 및 부싱 너트의 나선이 파손되는 것을 방지할 수 있는 탭핑머신용 마스터 스핀들을 제공하는 것이다.Another object of the present invention is to arrange the chip cover in the form of an umbrella at the bottom of the chuck support member to prevent the chip brake of the small particles from entering between the bushing nut and the spindle bolt, thereby preventing the spiral of the spindle bolt and the bushing nut to be broken. It is to provide a master spindle for a tapping machine.

본 발명의 또 다른 목적은 상기 척지지부재에 탭공구의 분리를 용이하게 하는 탭공구 분리용 구멍이 형성되어, 버티컬 타입으로 탭가공을 수행할 때 작은 입자의 칩 브레이크가 척으로 유입되어도, 상기 탭공구 분리용 구멍을 통해 탭의 하단을 척에서 밀어낼 수 있어, 탭공구를 척에서 언제나 분리할 수 있는 탭핑머신용 마스터 스핀들을 제공하는 것이다.Yet another object of the present invention is to form a hole for tapping tool to facilitate the separation of the tapping tool in the chuck support member, even when a small chip chip brake flows into the chuck when tapping in the vertical type, The tapping tool release hole allows the bottom of the tab to be pushed out of the chuck, thereby providing a master spindle for the tapping machine that can always remove the tapping tool from the chuck.

본 발명의 또 다른 목적은 부싱너트의 날개부에 탭핑구멍이 더 형성되어, 지그의 위치에 상관없이 부싱너트를 지그에 장착할 수 있는 탭핑머신용 마스터 스핀들을 제공하는 것이다.Still another object of the present invention is to provide a master spindle for a tapping machine, in which a tapping hole is further formed in a wing portion of the bushing nut, so that the bushing nut can be mounted on the jig regardless of the position of the jig.

상기와 같은 목적을 달성하기 위한 본 발명의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.

도 4를 참조하면, 본 발명에 따른 탭핑머신용 마스터 스핀들(50)은 탭공구(51)가 착탈 가능하게 장착되는 척(53)과, 상기 척(53)이 장착되는 척지지부재(55)와, 상기 척지지부재(55)에 상단부가 고정되는 스핀들 볼트(57)와, 상기 스핀들 볼트(57)에 체결되어 척지지부재(55)의 하부에 배치되는 부싱너트(59)로 구성된다.Referring to FIG. 4, the master spindle 50 for the tapping machine according to the present invention includes a chuck 53 on which the tab tool 51 is detachably mounted, and a chuck support member 55 on which the chuck 53 is mounted. And a spindle bolt 57 having an upper end fixed to the chuck support member 55, and a bushing nut 59 fastened to the spindle bolt 57 and disposed below the chuck support member 55.

상기 척지지부재(55)가 척(53)이 장착되는 상단부와 스핀들 볼트(57)가 고정되는 하단부가 일체로 형성된다. 이것은 스핀들 볼트(57)의 나선의 강도가 개선되고, 아래에서 설명하는 것처럼 작은 입자크기의 칩 브레이크가 스핀들 볼트(57)와 부싱너트(59) 사이로 들어가는 것을 방지하여, 스핀들 볼트(57)를 반영구적으로 사용할 수 있게 됨으로서, 굳이 종래와 같이 척지지부재를 나눌 필요성이 없어지게 되었다.The chuck support member 55 is integrally formed with an upper end at which the chuck 53 is mounted and a lower end at which the spindle bolt 57 is fixed. This improves the strength of the helix of the spindle bolts 57 and prevents chip breaks of small particle size from entering between the spindle bolts 57 and the bushing nut 59, as described below, thus making the spindle bolts 57 semipermanent. By being able to use it, there is no need to divide the chuck support member like the conventional.

이와같이, 척지지부재(55)의 상하단이 일체로 형성되므로서, 종래의 마스터실린더에서 발생하는 동심도 불일치 문제가 해결되고, 척지지부재(55)의 전체 길이(S)를 줄일 수 있어, 작업시 흔들림이 적고 작업의 정확도가 향상되는 효과를 얻을 수 있다.As such, since the upper and lower ends of the chuck support member 55 are integrally formed, the concentricity mismatch problem occurring in the conventional master cylinder can be solved, and the overall length S of the chuck support member 55 can be reduced. It is possible to obtain the effect of less shaking and improving the accuracy of the work.

상기 척지지부재(55)는 하단부에 우산형태의 칩커버(61)가 배치되어, 도 5에 도시된 바와같이, 버티컬 타입으로 탭가공 작업을 수행하여도 칩커버(61)가 공작물(도시하지 않음)에서 떨어지는 칩 브레이크(71)가 부싱너트(59)와 스핀들 볼트(57) 사이로 작은 입자의 칩 브레이크(71)이 들어가는 것을 방지할 수 있어, 스핀들 볼트(57) 및 부싱 너트(59)의 나선이 파손되는 것을 방지할 수 있다.The chuck support member 55 is an umbrella-shaped chip cover 61 is disposed at the lower end, as shown in Figure 5, even if the tab processing in the vertical type to the chip cover 61 is a workpiece (not shown) Chip break 71 falling from the bushing nut 59 and the spindle bolt 57 can prevent the chip brake 71 from entering into the small space. The spiral can be prevented from being broken

상기 척지지부재(55)는 척(53)의 하부에 탭공구(51)의 분리를 용이하게 하는 탭공구 분리용 구멍(63)이 형성되어, 도 5에 도시된 바와같이, 버티컬 타입으로 탭가공을 수행할 때 작은 입자의 칩 브레이크(57)이 척(53)으로 유입되어 탭공구(51)가 척(53)에서 빠지지 않을 경우, 막대기(도시하지 않음) 등을 상기 탭공구 분리용 구멍(63)에 넣어 탭공구(51)의 하단을 척(53)에서 밀어내므로서, 탭공구(51)를 척(53)에서 언제나 분리할 수 있다.The chuck support member 55 has a tab tool separation hole 63 for facilitating separation of the tab tool 51 at the lower portion of the chuck 53, and as shown in FIG. 5, the tab has a vertical type. When the chip break 57 of the small particles enters the chuck 53 when the machining is performed, and the tap tool 51 does not come out of the chuck 53, a rod (not shown) or the like is used to separate the tap tool. The tab tool 51 can be detached from the chuck 53 at any time by pushing the lower end of the tab tool 51 out of the chuck 53.

도 6을 참조하면, 상기 부싱너트(59)는 날개부(59a)에 장착구멍(59b)외에 탭구멍(59c)이 더 형성된다. 이것에 의해, 도 5에 도시된 것처럼 지그(73)가 부싱너트(59)의 날개부(59a) 하부에 배치될 경우, 볼트(75)가 장착구멍(59b)을 통과하여 지그(73)의 탭구멍(73b)에 체결되므로서, 부싱너트(59)가 지그(73)에 고정될 수 있다. 또한, 도 7에 도시된 것처럼 지그(73)가 부싱너트(59)의 날개부(59a) 상부에 배치될 경우, 볼트(77)가 지그(73)의 장착구멍(73b)을 통과하여 날개부(59b)에 형성된 탭구멍(59c)에 체결되므로서, 부싱너트(59)가 지그(73)에 고정될 수 있다. 따라서, 부싱너트(59)의 장착구멍(59b)과 탭구멍(59c)은 지그(73)의 위치에 상관없이 부싱너트(59)가 지그(73)에 고정될 수 있게 한다.Referring to FIG. 6, the bushing nut 59 is further provided with a tab hole 59c in addition to the mounting hole 59b in the wing portion 59a. As a result, when the jig 73 is disposed below the wing portion 59a of the bushing nut 59 as shown in FIG. 5, the bolt 75 passes through the mounting hole 59b to prevent the jig 73. By being fastened to the tab hole 73b, the bushing nut 59 can be fixed to the jig 73. In addition, when the jig 73 is disposed above the wing portion 59a of the bushing nut 59 as shown in FIG. 7, the bolt 77 passes through the mounting hole 73b of the jig 73 to form a wing portion. By being fastened to the tab hole 59c formed in the 59b, the bushing nut 59 can be fixed to the jig 73. Therefore, the mounting hole 59b and the tab hole 59c of the bushing nut 59 allow the bushing nut 59 to be fixed to the jig 73 regardless of the position of the jig 73.
