[고안의 상세한 설명][Detailed Description of Design]

본 고안은 공작기계용 스핀들 베어링의 예압조정장치에 관한 것으로서, 더욱 상세하게 말하자면 선반과 같은 공작기계의 스핀들 베어링 예방조정시 조립작업에서 발생하는 작업의 번거로움을 제거하고, 베어링의 손상을 방지할 수 있도록 한 공작기계용 스핀들 베어링의 예압조정장치에 관한 것이다.The present invention relates to a preload adjusting device for a spindle bearing for a machine tool, and more specifically, to prevent the hassle of assembly work and prevent damage to the bearing during the spindle bearing preventive adjustment of a machine tool such as a lathe. A preload adjusting device for spindle bearings for machine tools.

일반적으로 종래에는 제2도에 도시되어 있는 바와 같이, 스핀들(1)을 조립대에 안치시킨 후 볼트로 고정한 뒤, 스핀들(1)에 롤러 베어링(4)을 삽입시킨다. 이렇게 삽입된 롤러 베어링(4)의 외주연에 인디케이터(INDICATOR)로 측정하여 적절한 유동이 발생될 때 도시된 도면 제3도에서와 같이 길이(a)를 측정한 후, 롤러 베어링(4)을 빼낸다. 다음에, 래버린스(LABYRINTH) (3)를 길이(a)에 맞게 연마하여 스핀들(1)에 래버린스(2, 3)와 를러 베어링(4)을 삽입시켜 지그(7)로 강제 삽입시킨다. 이어서, 칼러(5)(6)와 볼베어링(7)을 지크(G)로 강제 삽입시키고, 이 외부에 칼러(8)를 조립한 후, 로크너트(10)로 체결시켜 고정한다. 그리고, 프론트 하우징(9)을 조릴하여 유동상태를 측정하여 허용치를 초과하는 경우에 각 부품을 해체하여 재조립한다.In general, as shown in FIG. 2, the spindle 1 is placed on an assembly table, fixed with a bolt, and then the roller bearing 4 is inserted into the spindle 1. Measure the length (a) as shown in FIG. 3 when the appropriate flow is generated by measuring with an indicator (INDICATOR) on the outer periphery of the inserted roller bearing 4, then remove the roller bearing (4) . Next, the labyrinth LABYRINTH 3 is ground to the length a, and the labyrinth 2 and 3 and the roller bearing 4 are inserted into the spindle 1 and forcedly inserted into the jig 7. Subsequently, the collars 5, 6 and the ball bearings 7 are forcibly inserted into the jigs G, and after the collars 8 are assembled to the outside, the lock nuts 10 are fastened and fixed. Then, the front housing 9 is assembled and the flow state is measured to disassemble and reassemble each component when the allowable value is exceeded.

그러나, 이와 같은 종래의 기술은, 롤러베어링(4)의 예압 조정용 래버린스(3)을 조립함에 있어 길이 ‘a’를 측정하여 를러 베어링(4)의 조립 및 해체를 반복 시행함으로써 조립공정이 번거롭고, 조립시간이 많이 걸리며, 롤러 베어링(4)의 손상을 가져오는 폐단이 있었다.However, such a conventional technique is cumbersome by repeating the assembly and disassembly of the roller bearing 4 by measuring the length 'a' in assembling the preload adjusting labyrinth 3 of the roller bearing 4. It takes a lot of assembly time, there was a closed end that causes damage to the roller bearing (4).

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 선반과 같은 공작기계의 스핀들 베어링 예방조정시 작업에서 발생하는 작업의 번거로움을 제거하고, 베어링의 손상을 방지할 수 있도록 스핀들 베어링의 예압조정이 용이하도록한 공작기계용 스핀들 베어링의 예압조정장치를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, the spindle bearing to remove the hassle of work occurring in the operation during the spindle bearing preventive adjustment of machine tools such as lathes, and to prevent damage to the bearing To provide a preload adjusting device for a spindle bearing for a machine tool to facilitate the preload adjustment.

이하. 첨부된 도면에 의하여 본 고안의 바람직한 실시예를 상세하게 설명하면 다음과 같다Below. When described in detail preferred embodiments of the present invention by the accompanying drawings as follows.

제1도에 도시되어 있는 바와 같이 본 고안의 실시예에 따른 공작기계용 스핀들 베어링의 예압조정장치의 구성은, 조립대에 볼트로 고정되어 있는 스핀들(1)의 외주연에 래버린스A(2)와 래버린스B(3)와 롤러베어링(4)과 칼러(5)와 볼베어링(7)과 칼러(8)와 로크너트(10)를 순차적으로 삽입시킨 후 프론트하우징(9)을 조립시키고, 이 외부에 중공부(l1A)를 가진 바디(11)를 삽입시키고, 스핀들(1)에 인디케이터를 접촉시켜 적정한 유동이 발생할때까지 로크너트(10)를 체결시키고, 스핀들(1)의 유동이 허용치 내에 위치되면 세트스크류(12)로 래버린스B(3)을 고정하는 구조로 이루어진다As shown in FIG. 1, the configuration of the preload adjusting device of the spindle bearing for a machine tool according to the embodiment of the present invention is a labyrinth A (2) at the outer periphery of the spindle 1 that is bolted to the assembly table. ), The labyrinth B (3), roller bearing (4), collar (5), ball bearing (7), collar (8) and lock nut (10) are inserted in sequence, and then the front housing (9) is assembled. A body 11 having a hollow portion l1A is inserted into the outside thereof, the indicator is brought into contact with the spindle 1 to engage the lock nut 10 until proper flow occurs, and the flow of the spindle 1 is allowed to flow. When positioned in the interior is made of a structure for fixing the labyrinth B (3) with a set screw (12).

이와 같은 구성에 의한 본 고안의 실시띠에 따른 공작기계용 스핀들 베어링의 예압조정장치는, 롤러베어링(4)의 예압량을 결정하기 위하여 롤러베어링(4)을 스핀들(1)에 조립하여 해체하는 작업을 제거시키고, 조립중에 래버린스B(3)을 연마하는 작업을 없앰으로써 예압량이 잘못 결정된다 하더라도 스핀들(7)의 외부에 삽입된 각 부품들의 전체를 분해 및 재조립할 필요를 없애줌으로써 각 부품들의 손상을 방지하고 따라서 조립시간을 단축시킬 수 있게 된다.The preload adjusting device of the spindle bearing for a machine tool according to the embodiment of the present invention by such a configuration is to assemble and disassemble the roller bearing 4 to the spindle 1 in order to determine the preload amount of the roller bearing 4. Removal of the labyrinth B (3) during assembly, eliminating the need to disassemble and reassemble all of the components inserted outside of the spindle (7) even if the preload amount is incorrectly determined. It is possible to prevent damage and thus shorten the assembly time.

이상에서와 같이 본 고안은 선반과 같은 공작기계의 스핀들 베어링 예방조정시 작업에서 발생하는 작업의 번거로움을 제거하고, 베어링의 손상을 방지할 수 있도록 함으로써 스핀들 베어링의 예압조정을 용이하게 할 수 있는 효과가 있다.As described above, the present invention can facilitate the preload adjustment of the spindle bearing by removing the trouble of the work occurring in the operation of the spindle bearing of the machine tool such as a lathe and preventing damage to the bearing. It works.
