Description

공작물 모따기장치Workpiece chamfer

본 발명은 공작물의 날카로운 모서리 또는 구석을 비스듬하게 깎는 모따기장치에 관한 것으로, 더욱 구체적으로는 공작물의 직선 또는 원호상으로 된 내·외 주연부 형태나 크기에 관계없이 모따기가 가능하고 다용도로 간편하고 효율적으로 작업할수 있는 모따기장치에 관한 것이다.The present invention relates to a chamfering device for cutting sharp edges or corners of a workpiece at an angle, and more particularly, to chamfering regardless of the shape and size of the inner and outer circumferences of the straight or arc shape of the workpiece. It is about a chamfer device that can work with.

종래의 모따기장치는 내주연부 모따기 전용이거나 외주연부 모따기 전용으로 사용되었는바 이는 공작물의 내주연부나 외주연부에 절삭날을 이동시키면서 모따기작업을 행하기 위해서는 절삭날가이드를 따로 구비시켜야 되고 공작물을 고정시킨 다음 작업을 해야되므로 작업효율이 떨어지게 되었다.Conventional chamfering device is used only for the inner circumference chamfer or the outer circumference chamfer, which must be equipped with a cutting edge guide separately to carry out the chamfering operation while moving the cutting edge on the inner circumference or outer circumference of the workpiece. Since the next work must be done, the work efficiency is reduced.

그래서 대부분의 모따기작업은 핸드그라인더를 들고 공작물의 내·외주연부에 일정한 경사가 지도록 절삭작업을 하였으므로 절삭면이 일정하지 못하고 울퉁불퉁하게 되는 문제점이 있을뿐만 아니라 숙련된 기술을 필요로 하였었다.Therefore, most of the chamfering work was carried out by holding the hand grinder to cut a certain slope on the inner and outer circumferences of the workpiece, so that the cutting surface was not uniform and rugged, and also required skilled skills.

본 발명은 이러한 문제점을 해결하기 위하여 전동모터를 내장한 핸들의 회전축에 절삭날과 가이드베어링을 설치하고 회전축 외측의 결합관 외경에 오른나사부를 형성하여 승강안내관을 나사결합하고 결합관 내경에 왼나사부를 형성하여 가이드판을 가진 연결관을 나사결합하되 승강안내관 주연부에 눈금표시를 하여 가이드판의 높이를 작동손잡이로 승강안내관을 회전하여 맞추는 방법으로 절삭날의 절삭량을 조절할수 있도록 한 것이다.In order to solve the above problems, the present invention installs a cutting blade and a guide bearing on a rotating shaft of a handle incorporating an electric motor, and forms a right-hand screw portion in an outer diameter of a coupling tube outside the rotating shaft, thereby screwing the elevating guide tube and a left screw in the coupling tube inner diameter. To form the part, screw the connecting pipe with the guide plate, and mark the periphery of the lifting guide tube to adjust the cutting amount of the cutting edge by rotating the lifting guide tube by adjusting the height of the guide plate with the operation knob.

도 1 내지 도 3에서와 같이 전동모터를 내장한 핸들(1)의 회전축(2) 선단에 가이드베어링(205)을 축설하고 이 가이드베어링(205) 내측의 회전축경사면(201)에 절삭칩(203)이 약간 돌출되게 하여 절삭날(202)을 나사(204)로 고정시킨다.As shown in FIGS. 1 to 3, a guide bearing 205 is formed at the tip of the rotation shaft 2 of the handle 1 having the electric motor built therein, and the cutting chip 203 is formed on the rotation shaft inclined surface 201 inside the guide bearing 205. ) So that the cutting edge 202 is fixed with the screw 204.

상기 회전축(2) 회전을 간섭하지 않는 외측에 결합관(3)을 설치하고 결합관(3) 외경에 오른나사부(301)를 형성하여 승강안내관(4)을 나사결합하고 승강안내관(4) 주연부에 눈금표시(401)를 하여 결합관(3)외주의 기준선(303)과 맞출수 있게 하되 승강안내관(4) 외주연에 결합한 작동손잡이(402)를 회전하여 승강안내관(4) 높이를 조절케한다.Installing the coupling pipe (3) on the outside does not interfere with the rotation of the rotary shaft (2) and the right screw portion 301 is formed on the outer diameter of the coupling pipe (3) to screw the lifting guide tube (4) and the lifting guide tube (4) ) The scale mark 401 on the periphery of the coupling pipe (3) can be aligned with the reference line 303 of the outer periphery, but the lifting guide tube (4) by rotating the operation knob 402 coupled to the outer periphery of the lifting guide tube (4) height To adjust.

결합관(3) 내경에는 회전축(2) 회전방향과 같은 왼나사부(302)를 형성하여 회전축(2)과 직교된 방향의 가이드판(5a)을 가진 연결관(5)을 나사결합하되 승강안내관(4)에 대응결합되게 하여 가이드판(5a)의 결합높이에 따라 절삭날(202)의 절삭량이 조절되게 한다.In the inner diameter of the coupling pipe (3), the left screw portion (302) is formed in the same direction as the rotation axis (2), and the coupling pipe (5) having the guide plate (5a) in the direction orthogonal to the rotation shaft (2) is screwed, The cutting amount of the cutting edge 202 is adjusted according to the coupling height of the guide plate 5a by being correspondingly coupled to the pipe 4.

도 4 및 도 5에서는 가이드판(5a)과 직교된 직각면(601)을 갖는 직각안내구(6)를 가이드판(5a)에 편심되게 볼트(603)로 결합하여 가이드판(5a)의 결합홈(5')에 직각안내구(6)의 결합돌기(6')가 지지되게 하고 직각안내구(6)에 일측이 개구된 안내구멍(602)을 형성하여서된 것이다.4 and 5, the guide plate 5a is coupled to the guide plate 5a by the bolt 603 to be eccentrically coupled to the guide plate 5a with the right angle guide 6 having the perpendicular surface 601 orthogonal to the guide plate 5a. The coupling protrusion 6 'of the right angle guide 6 is supported in the groove 5' and the guide hole 602 having one side opened in the right angle guide 6 is formed.

이와같이 본 발명은 핸들(1)의 결합관(3)에 승강안내관(4)을 나사결합하면서 결합위치는 승강안내관(4)의 눈금표시(401)를 기준선(303)에 맞추어 조절한 다음 가이드판(5a)을 가진 연결관(5)을 결합하여 승강안내관(4)에 맞대응시키게 되면 결합관(3)에 가이드판(5a)이 설정위치에 긴밀히 고정된 상태를 유지하게 된다.As such, the present invention, while screwing the elevating guide pipe (4) to the coupling pipe (3) of the handle (1), the coupling position is adjusted to the reference line 303 to the scale mark 401 of the elevating guide pipe (4) When the coupling pipe (5) having a guide plate (5a) is coupled to the lifting guide tube (4) to match the guide plate (5a) to the coupling pipe 3 is maintained in a tightly fixed position at the set position.

즉, 가이드판(5a)의 연결관(5)은 왼나사로 결합되어 있고 승강안내관(4)은 오른나사로 결합되어 있어서 고정상태를 유지시키게 되며, 이렇게 고정된 상태에서 승강안내관(4)을 작동손잡이(402)를 돌려 간편하게 고정상태를 푼다음 승강안내관(4)을 회전하여 가이드판(5a)에서 절삭날(202)의 돌출부분을 다르게 하는 방법으로 절삭량을 조절할수 있게된다.That is, the connecting pipe 5 of the guide plate 5a is coupled to the left screw and the lifting guide tube 4 is coupled to the right screw to maintain the fixed state, and thus the lifting guide tube 4 in the fixed state. By simply turning the operation knob 402 to loosen the fixed state and then rotating the lifting guide tube 4, the cutting amount can be adjusted by varying the protrusion of the cutting edge 202 on the guide plate 5a.

예를들면, 공작물의 모따기를 크게 할 때에는 가이드판(5a)의 연결관(5)을 상승시켜 가이드판(5a)의 외측으로 절삭날(202)을 많이 돌출시키면 공작물에 절삭날(202) 접촉면이 커지면서 절삭량이 많게되고, 모따기를 작게 할 때에는 가이드판(5a)의 연결관(5)을 하강시켜 가이드판(5a) 외측으로 절삭날(202) 돌출부위가 작게하면 절삭날(202) 접촉면에 의한 절삭량이 감소된다.For example, to increase the chamfer of the workpiece, when the connecting pipe 5 of the guide plate 5a is raised to protrude the cutting edge 202 to the outside of the guide plate 5a, the cutting edge 202 is in contact with the workpiece. The larger the cutting amount is, the smaller the chamfer is. When the chamfer is made smaller, the connecting pipe 5 of the guide plate 5a is lowered and the cutting edge 202 protruding portion outside the guide plate 5a becomes smaller. The amount of cutting due to this is reduced.

이렇게 절삭량조절을 한 다음 전동모터를 회동시킨 핸들(1)을 잡고 공작물의 내·외주면 모따기부분에 절삭날(202)을 맞댄 상태에서 가이드베어링(205)을 그 주벽에 누르면서 이동시키게 되면 절삭날(202)에 의해 모따기가 이루어진다.After adjusting the cutting amount, hold the handle (1) rotated by the electric motor, and move the guide bearing 205 while pressing the circumferential wall to the chamfered part of the workpiece. The chamfer is made by 202.

이때, 본 발명은 절삭날(202)이 가이드베어링(205)을 따라 안내되므로 직선 또는 원호상으로된 내·외주연부의 모따기가 가능하다At this time, in the present invention, since the cutting edge 202 is guided along the guide bearing 205, it is possible to chamfer the inner and outer circumferences of the straight or arc shape.

그리고, 많은량의 공작물을 직선으로만 모따기를 해야될때에는 도 4 및 도 5에서와 같이 가이드판(5a)에 직각안내구(6)를 결합하여 작업하게 되면 가이드베어링(205)을 누르는 작업을 하지않고 간편하고 신속하게 작업을 할수있게 된다.In addition, when chamfering a large amount of workpieces only in a straight line, as shown in FIGS. 4 and 5, when the right angle guide 6 is coupled to the guide plate 5a, the operation of pressing the guide bearing 205 is performed. You can do it simply and quickly.

이와같이 본 발명은 다용도로 간편하게 공작물의 직선 또는 원호상의 내·외주연부 모따기가 가능하며 절삭량조절이 간편하고 그 구조도 간단한 이점이 있는 것이다.In this way, the present invention is versatile and easy to chamfer the inner and outer periphery of the straight line or arc of the workpiece, the cutting amount is easy to control and its structure is also simple advantages.
