Description

일체형 정밀로크너트{A accuracy lock nut for one body}Integral Precision Lock Nuts {A accuracy lock nut for one body}

본 발명은 일체형 정밀로크너트에 관한 것으로서, 더욱 상세하게는 공작기계나 산업기계의 베어링과 같은 정밀부품의 체결스크류에 고정되는 체결너트로서 너트본체의 양측에 일체로 절개된 절개부를 형성하여 체결스크류에 너트본체의 완벽하게 고정시킬 수 있을 뿐만 아니라 체결스크류에 너트본체를 용이하게 체결할 수 있는 일체형 정밀로크너트에 관한 것이다.
The present invention relates to an integrated precision lock nut, and more particularly, to a fastening screw fixed to a fastening screw of a precision part such as a bearing of a machine tool or an industrial machine. The present invention relates to an integral precision lock nut that can not only completely fix the nut body to the nut body but also can easily fasten the nut body to the fastening screw.

일반적으로, 정밀한 기계류는 사용시 회전축에 체결되는 베어링의 정밀함과 더불어 상기 베어링을 회전축에 체결시키는 로크너트가 매우 중요한 영향을 미친다.In general, the precision machinery has a very important influence on the lock nut which fastens the bearing to the rotating shaft as well as the precision of the bearing which is fastened to the rotating shaft.

이와 같은 로크너트는 정밀기계의 회전축에 고정되는 베어링을 체결하여 풀림을 방지하는 수단으로 사용되며, 상기 풀림을 방지하는 수단은 정밀한 기계류에서 정밀도를 유지하기 위하여 매우 중요한 요소로서, 로크너트의 회전축 중심에 대한 단면 직각도가 풀림방지에 큰 영향을 주게 된다. The lock nut is used as a means for preventing loosening by fastening a bearing fixed to the rotating shaft of a precision machine. The preventing means is a very important factor for maintaining precision in the precision machinery. The squareness of the cross section has a significant effect on the prevention of loosening.

최근에 정밀부품을 체결하기 위한 로크너트가 개발되어 체결용 너트의 풀림을 방지하는 기술이 출시되어 있다.Recently, a lock nut for fastening precision parts has been developed, and a technology for preventing loosening of the fastening nut has been released.

도 1은 종래의 로크너트를 나타낸 개요도로서, 도시된 바와 같이, 종래의 로크너트는 기계장치의 회전축 스크류와 체결되는 너트본체(1)와, 상기 너트본체(1)의 내측에 황동재의 고정핀(2)이 삽입되고, 상기 고정핀(2)의 상측에는 볼트형의 고정볼트(3)가 구비되어 체결기구를 이용하여 좌우로 회전시키면 상기 고정핀(2)이 상기 회전축의 스크류 나사부에 밀착되어 너트본체(1)가 스크류에서 풀리는 것이 방지된다.1 is a schematic view showing a conventional lock nut, as shown in the drawing, a conventional lock nut is a nut main body (1) coupled to a rotating shaft screw of a mechanical device, and a fixing pin made of brass inside the nut main body (1) (2) is inserted, and the fixing pin (3) of the bolt type is provided on the upper side of the fixing pin (2) and rotates left and right using a fastening mechanism, the fixing pin (2) is in close contact with the screw screw portion of the rotating shaft This prevents the nut body 1 from being loosened from the screw.

그러나, 종래의 로크너트는 상기 고정핀(2)의 일부가 기계장치의 스크류에 고정는 구조이므로 고정되는 접촉면적이 매우 적으므로 회전축의 스크류가 정회전과 역회전이 반복적으로 발생되거나 회전축이 고속으로 회전될 경우 너트본체(1)가 풀리게 되어 정밀하게 체결할 수 있는 정밀부품체결용으로 사용하기 곤란한 문제점이 있었으며, 고정핀(2)을 별도로 구비하고 상기 고정핀(2)을 안착시키기 위하여 너트본체(1)에 고정홈을 형성시키기 위한 공정이 소요되므로 제조비용이 증가되는 문제점도 있었다.
However, the conventional lock nut has a structure in which a part of the fixing pin 2 is fixed to the screw of the mechanical device, so that the contact area to be fixed is very small, so that the forward and reverse rotation of the screw of the rotating shaft occurs repeatedly or the rotating shaft is rotated at high speed. When rotated, the nut body (1) is loosened, so there is a problem that it is difficult to use for fastening the precision parts that can be tightened precisely, and provided with a fixing pin (2) separately and to seat the nut pin (2) There was also a problem that the manufacturing cost is increased because the process for forming the fixing groove in (1) takes.
