본 고안은 엔코더의 유리디스크 고정장치에 관한 것으로서, 특히 유리디스크의 중앙에 엔코더의 측에 결합하기 위한 구명이 필요없이 표시부로서 엔코더의 고정구 평면에 안착되게 하여 유리디스크의 구멍가공으로 인한 고단가를 저렴하게 할 수 있음과 동시에 그 정확한 동심을 맞추게에 적합하도록 안출된 것이다.The present invention relates to a glass disk fixing device of the encoder, and in particular, the display unit is mounted on the fixture plane of the encoder as a display unit without the need for a life-saving coupling to the encoder side. It is designed to be affordable and at the same time suitable for the correct concentricity.
일반적으로 엔코더는 디스크의 정보를 읽어내기 위한 기구장치로서 종래에는 도면 제1도에서와 같이, 프레임(1)에 베어링(11)으로 축(12)를 돌설되게 결합하고 돌설된 축이 내경에 축과 동일한 디스크 고정구(13)를 결합하고 상면에 도면 제2도에서와 같은 축보다 약간 큰 직경을 가지는 유리디스크(20)의 구멍(21)을 상기축(12)에 끼우고 링(14) 및 탄성력을 가지는 스냅링(15)으로 장착시켜 고정된 것으로, 도면중 미설명부호 22는 슬리트이고 3은 인덱스 슬리트이다.In general, an encoder is a mechanism device for reading information of a disk. Conventionally, as shown in FIG. 1, a shaft 12 is projectedly coupled to a frame 1 by a bearing 11, and the protruding axis is an axis of an inner diameter. And the hole (21) of the glass disc (20) having a diameter slightly larger than the axis as shown in FIG. It is fixed by mounting with a snap ring 15 having an elastic force, the reference numeral 22 in the drawing is a sled and 3 is an index sled.
그러나 이와 같이 구성된 종래의 엔코더의 유리디스크 고정장치는 유리의 재질상 비정질이므로 작은 충격에도 쉽게 깨지기 때문에 축(12)에 결합되는 유리디스크(2)의 직경 5-20mm의 구멍(21)을 가공하기가 매우 어려우며, 특히 그 정확한 엔코딩을 위해서는 디스크(2)와 인덱스 슬리트(3)의 슬리트(22)가 정확히 맞아야 하기 때문에 유리디스크(2)의 구멍(21)이 0.01mm공차로 가공되야 하므로 더더욱 그 제작이 어려워 불량율을 높이는 동시에 유리 디스크의 제작 단가를 상승시키며, 디스크(2)의 조립시 링(14) 및 스냅링(15)의 조립을 위한 작은 충격에도 쉽게 파손되는 것과 그 분해결합이 용이치 못한 등의 많은 문제점을 가지고 있었다.However, the glass disc fixing device of the conventional encoder configured as described above is amorphous because of the material of glass, so it is easily broken even by a small impact, so that the hole 21 having a diameter of 5-20 mm of the glass disc 2 coupled to the shaft 12 is processed. Is very difficult, and in particular the holes 21 of the glass disc 2 must be machined to a 0.01 mm tolerance because the slits 22 of the disc 2 and the index slits must fit exactly for the correct encoding. In addition, it is difficult to manufacture, which increases the defective rate and increases the manufacturing cost of the glass disk, and is easily broken even by a small impact for assembling the ring 14 and the snap ring 15 when assembling the disk 2 and its disassembly and coupling. There were many problems such as this.
따라서 본 고안은 상기와 같은 문제점을 감안하여 유리디스크의 결합을 생략하는 동시에 동심원 표시부만 두고 축이 상부로 돌설되지 않게 동심원상의 홈부를 가지는 고정구를 결합하여 디스크와 본딩결합되게 하므로써 유리디스크의 제작 및 그 단가를 대폭저렴하게 제공함은 물론 조립 및 분해로인한 파손을 방지하고, 탈부착이 간단하며 동심원을 맞추기가 용이하도록 하는데 그 목적이 있다.Therefore, the present invention omits the coupling of the glass disk in view of the above problems, and at the same time, combines the fasteners having the concentric grooves so that the shaft does not protrude upwards, but bonds the disk with the disk. Its purpose is to provide a significantly lower cost, as well as to prevent breakage due to assembly and disassembly, and to facilitate detachment and easy concentricity.
이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제3도 및 제4도에 도시하는 바와 같이 본 고안 장치는 프레임(1)에 베어링(11)으로서 결합된 축(12) 상부에 결합되는 고정구와 유리디스크를 고정하기 위한 것에 있어서; 축(12)의 돌출되지 않는데 삽입결합되는, 상부에 축과의 동심원 상에 적어도 1개소 이상의 동심원홈부(41)와 방사상홈부(42)를 구비한 고정구(4)와; 저부중앙에는 상기 고정구(4)의 동심원 홈부(41)와 같은 동심원 표시부(51)가 형성된 유리디스크(5)를 접착제(6)로서 접설하여 고정된 것으로, 상기 고정구(4)의 방사상홈부(42)는 등각도로 구성되며, 또 다른 동심원 홈부(41)의 단면은 도면 제5도에서와 같이 사각홈이거나 또는 도면 제6도에서와 같이 삼각홈으로 형성함을 특징으로 한다.As shown in FIG. 3 and FIG. 4, the device of the present invention is for fixing a glass disk and a fixture coupled to an upper portion of a shaft 12 coupled as a bearing 11 to a frame 1; A fastener (4) having at least one or more concentric grooves (41) and radial grooves (42) on a concentric circle with the shaft on the top, which is inserted but not protruding from the shaft (12); In the bottom center, the glass disk 5 having the concentric circle display portion 51, such as the concentric groove portion 41 of the fastener 4, is folded and fixed as an adhesive 6, and the radial groove portion 42 of the fastener 4 is fixed. ) Is formed at an isometric angle, and the cross section of another concentric groove 41 is formed as a square groove as shown in FIG. 5 or a triangular groove as shown in FIG.
이상과 같이 구성된 본 고안의 작용효과를 장착상태에 따라 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above according to the mounting state as follows.
먼저 제3a도 및 b도에서와 같이 고정구(4)의 의상면에 접착제(6)를 도포한 후, 유리디스크(5)의 중심이 투명체이기 때문에 저부에 표시부(51)를 고정구(4)의 동심원 홈부(41)에 맞추어 유리디스크(5)를 2-3회 좌우회전 시키면서 축(12)과의 동심을 맞추게 되는데, 이때 접착제(6)의 양이 너무 많으면 고정구(4)의 동심원홈부(41)에서 방사상홈부(42)를 걸쳐 밖으로 나오게 되며 접착제가 고루도포된 상태에서 홈부를 제외한 고정구(4) 상면과 유리디스크(5)가 접착고정되어 정확한 수평면을 얻을 수가 있다.First, as shown in FIGS. 3A and 3B, the adhesive 6 is applied to the clothes surface of the fastener 4, and then the display portion 51 is placed on the bottom of the fastener 4 since the center of the glass disc 5 is a transparent body. Concentric with the shaft 12 while rotating the glass disk 5 left and right 2-3 times in accordance with the concentric groove 41, in this case, if the amount of the adhesive 6 is too large, the concentric groove 41 of the fixture 4 ) Out of the radial groove 42 and the adhesive is evenly coated in the state that the upper surface of the fixture 4 and the glass disk (5) except the groove is bonded and fixed to obtain an accurate horizontal plane.
또한 분해시에는 유기용제에 의해 접착부위가 쉽게 용해되어 간단히 분해시킬 수가 있다.At the time of decomposition, the adhesive site is easily dissolved by the organic solvent and can be easily decomposed.
이상에서 설명한 바와 같이 본 고안은 유리디스크에 구멍을 가공할 필요가 없으므로 기공시 유리 파손으로 인한 고단가의 문제를 해결하고 링과 스냅링등의 부품을 생략할 수가 있어 원가절감은 물론 이로인한 조립시의 디스크파손을 해소할 수가 있고, 동시 디스크의 동심원 표시부와 고정구의 동시원홈부로서 간단히 그 동심원 및 수평도를 정확히 맞출 수 있어 엔코더의 정밀도를 더욱 향상시킬 수가 있다는 매우 유용한 고안인 것이다.As described above, the present invention eliminates the need to process holes in the glass disk, thus solving the problem of high cost due to glass breakage during pore and eliminating parts such as rings and snap rings. It is a very useful design that can solve the disk breakage of the disk, and can easily match the concentric circles and the horizontal degree as the concentric circle display portion of the simultaneous disk and the simultaneous circle groove portion of the fixture.
