절단기의 톱날축베어링 조립용 지그{Jig for assembling Saw shaft bearing of Cutter}Jig for assembling Saw shaft bearing of Cutter}

본 고안은 절단기의 톱날축베어링 조립용 지그에 관한 것으로서, 보다 상세하게는 절단기의 톱날축의 전동측에 구비되는 베어링을 조립하는 지그에 관한 것이다.The present invention relates to a jig for assembling a saw blade shaft bearing of a cutter, and more particularly, to a jig for assembling a bearing provided on the transmission side of a saw blade shaft of a cutter.

일반적으로 톱날 절단기는, 톱날축이 베어링을 매개로 몸체에 회전가능케 지지되고, 상기 톱날축의 일측에 톱날이 결합되고, 톱날축의 타측에 동력을 전달받는 전동풀리가 결합된 구조를 포함하고 있다.Generally, the saw blade cutter includes a structure in which the saw blade shaft is rotatably supported by the body via a bearing, the saw blade is coupled to one side of the saw blade shaft, and the electric pulley receives power to the other side of the saw blade shaft.

톱날 절단기에서 톱날축에 톱날 또는 전동풀리를 끼우도록 톱날축은 몸체에서 돌출되어 있는데, 베어링을 몸체에 조립할 때 해머 등을 사용하여 베어링을 타격하여 베어링 수용부에 끼우므로 톱날축이나 베어링이 손상될 우려가 있을 뿐만 아니라 조립작업이 어렵고 조립시간이 많이 걸린다는 문제점이 있었다.The saw blade shaft protrudes from the body to fit the saw blade or the electric pulley to the saw blade shaft in the saw blade cutter.When assembling the bearing to the body, the saw blade shaft or the bearing may be damaged by hitting the bearing with a hammer, etc. There was a problem that the assembly work is difficult and takes a lot of assembly time.

따라서, 본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 베어링과 톱날축의 손상없이 베어링을 용이하게 조립할 수 있는 절단기의 톱날축베어링 조립용 지그를 제공하는 데 있다. Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a jig for assembling a blade shaft bearing of a cutter which can easily assemble the bearing without damaging the bearing and the saw blade shaft.

본 고안에 의한 절단기의 톱날축베어링 조립용 지그는, 절단기의 톱날축의 전동측에 구비되는 베어링을 조립하는 지그로서, 베어링의 내륜과 외륜의 측면에 밀착하는 밀착부와, 상기 톱날축의 단부에 지지되게 끼워지며 상기 밀착부에 일단이 연결되는 연결부와, 상기 연결부의 타단에 구비되어 지그를 가압하는 가압부를 포함하는 것을 특징으로 한다.The jig for assembling the saw blade shaft bearing of the cutter according to the present invention is a jig for assembling a bearing provided on the electric side of the saw blade shaft of the cutter. It is characterized in that it comprises a connecting portion which is fitted so that the one end is connected to the close contact portion, the pressing portion is provided on the other end of the connecting portion for pressing the jig.

상기 가압부에는 상기 톱날축의 측면에 나사결합되는 나사부재에 의해 지그를 가압하도록 다수의 구멍이 형성되어 있다.The pressing portion is formed with a plurality of holes to press the jig by a screw member screwed to the side of the saw blade shaft.

본 고안에 의한 절단기의 톱날축베어링 조립용 지그에 의하면, 베어링과 톱날축의 손상없이 베어링을 용이하게 조립할 수 있고 조립시간을 단축할 수 있다는 효과가 있다.According to the jig for saw blade bearing assembly of the cutter according to the present invention, there is an effect that the bearing can be easily assembled without damaging the bearing and the saw blade shaft and the assembly time can be shortened.

이하, 본 고안의 실시예에 대해 첨부도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 상기 베어링(12)을 조립할 시에 사용되는 지그(100)이며, 상기 베어링(12)의 내륜과 외륜의 측면에 밀착하는 밀착부(110)와, 상기 톱날축(10)의 단부에 지지되게 끼워지며 상기 밀착부(110)에 일단이 연결되는 연결부(120)와, 상기 연결부(120)의 타단에 구비되어 지그를 가압하는 가압부(130)로 이루어진다. 상기밀착부(110)와 연결부(120) 및 가압부(130)는 하나의 부품으로 일체로 제조될 수도 있고, 각 부분이 분리된 상태로 제조되어 용접 등에 의해 일체화될 수도 있다.The present invention is a jig 100 used when assembling the bearing 12, the close contact portion 110 in close contact with the side of the inner ring and the outer ring of the bearing 12, and the end of the saw blade shaft 10 It is composed of a connecting portion 120 that is fitted to be supported and the one end is connected to the close contact portion 110, the pressing portion 130 is provided on the other end of the connecting portion 120 to press the jig. The contact part 110 and the connection part 120 and the pressing part 130 may be integrally manufactured as one component, or may be manufactured in a separate state to be integrated by welding or the like.

상기 밀착부(110)는 원통링 형태의 측면 중간에 원주방향을 따라 띠홈(111)이 형성되어, 상기 띠홈(111)의 내, 외측에는 상기 베어링(12)의 내륜 및 외륜에 밀착하는 내륜밀착면(112) 및 외륜밀착면(113)이 형성된다.The close contact portion 110 has a belt groove 111 formed along the circumferential direction in the middle of the side of the cylindrical ring shape, the inner ring is in close contact with the inner ring and the outer ring of the bearing 12 on the inside, the outside of the band groove 111 The surface 112 and the outer ring contact surface 113 is formed.

상기 연결부(120)는 파이프 형태로 되어 있으며, 그 내주면은 상기 톱날축(10)의 타측(10b) 외주면에 밀착되게 끼워져 지그를 지지하게 되어 있다. The connecting portion 120 is in the form of a pipe, and its inner circumferential surface is fitted in close contact with the outer circumferential surface of the other side 10b of the saw blade shaft 10 to support the jig.

상기 가압부(130)는 상기 연결부(120)의 일측을 막는 부분으로서, 그 중간부에는 상기 톱날축(10)의 측면에 나사결합되는 나사부재(24)에 의해 지그를 가압하도록 다수의 구멍(131)이 형성되어 있다. The pressing portion 130 is a portion blocking one side of the connecting portion 120, the middle portion of the plurality of holes to press the jig by the screw member 24 screwed to the side of the saw blade shaft 10 ( 131 is formed.

이와 같이 구성된 본 고안에 의한 지그(100)는, 도3에 도시한 바와 같이 베어링(12)을 몸체(16) 및 톱날축(10)에 조립할 때, 베어링(12)을 톱날축(10)의 타측(10b)에 우선 끼운 후, 지그(100)를 톱날축(10)의 타측(10b)에 끼워 상기 밀착부(110)의 내륜밀착면(112) 및 외륜밀착면(113)이 베어링(12)의 내륜 및 외륜의 측면에 밀착되게 하여 나사부재(24)를 상기 가압부(130)의 구멍(131)에 끼워 톱날축(10)의 나사구멍(10c)에 조우면, 연결부(120)의 내면이 톱날축(10)의 타측(10b) 외주면에 지지되어 베어링(12)을 밀게 되므로 베어링(12)과 톱날축(10)을 손상시키지 않고 용이하고 간단히 조립할 수 있다.In the jig 100 according to the present invention configured as described above, as shown in FIG. 3, when the bearing 12 is assembled to the body 16 and the saw blade shaft 10, the bearing 12 is connected to the saw blade shaft 10. After inserting the other side 10b first, the jig 100 is fitted to the other side 10b of the saw blade shaft 10 so that the inner ring contact surface 112 and the outer ring contact surface 113 of the contact portion 110 are the bearing 12. When the screw member 24 is inserted into the hole 131 of the pressing part 130 and tightly screwed to the screw hole 10c of the saw blade shaft 10, the inner side of the connecting portion 120 Since the inner surface is supported on the outer peripheral surface of the other side (10b) of the saw blade shaft 10 to push the bearing 12 can be easily and simply assembled without damaging the bearing 12 and the saw blade shaft (10).

한편, 상기 나사부재(24)를 사용하지 않고 별도의 가압수단(공압 등 이용)으로 지그(100)의 가압부(130)를 밀어서 베어링(12)을 조립할 수도 있다. Meanwhile, the bearing 12 may be assembled by pushing the pressing unit 130 of the jig 100 using a separate pressing means (such as pneumatic) without using the screw member 24.
