이러한 가동판체(30)와 코일유닛(40)은, 가동판체(30)를 관통하여 코일유닛 (40)에 나사 체결되는 체결볼트(50)에 의해 서로 조립된다. 즉, 가동판체(30)에 관통구멍(32)을 형성한다. The movable plate body 30 and the coil unit 40 are assembled to each other by a fastening bolt 50 that penetrates the movable plate body 30 and is screwed to the coil unit 40. That is, the through hole 32 is formed in the movable plate body 30.
그리고, 이에 대응되는 코일유닛(40)의 코어(42)에도 관통구멍(42a)을 형성한다. 그리고 코어(42)의 밑면에는 설치홈(42b)을 형성한 다음, 이 설치홈(42b)에는 절연지(46)를 개재하여 체결블록(48)을 압입한다. 이때, 체결블록(48)에는 체결구멍(48a)이 형성되어 있다.The through hole 42a is also formed in the core 42 of the coil unit 40 corresponding thereto. Then, an installation groove 42b is formed at the bottom of the core 42, and then the fastening block 48 is press-fitted through the insulating paper 46 in the installation groove 42b. At this time, a fastening hole 48a is formed in the fastening block 48.
이러한 상태에서 서로 정렬된 가동판체(30)의 관통구멍(32)과 코어(42)의 관통구멍(42a)과 체결블록(48)의 체결구멍(48a)에 체결볼트(50)를 끼워 나사 결합하는 것이다.In this state, the fastening bolt 50 is screwed into the through hole 32 of the movable plate body 30, the through hole 42a of the core 42, and the fastening hole 48a of the fastening block 48 aligned with each other. It is.
이러한 종래의 리니어 모터는, 가동자(20)의 가동판체(30)와 코일유닛 (40)을 조립하기가 매우 힘들고 번거로운 문제점이 있다. 즉, 종래에는 가동자(20)의 가동판체(30)와 코일유닛(40)을 조립하기 위해, 코일유닛(40)의 코어(42)에 관통구멍(42a)을 뚫은 다음, 코어(42)의 밑면에 설치홈 (42b)을 가공해야 하고, 가공된 설치홈(42b)에 체결블록(48)을 압입해야 하는 번거로움이 있었다. Such a conventional linear motor has a problem that it is very difficult and cumbersome to assemble the movable plate body 30 and the coil unit 40 of the mover 20. That is, conventionally, in order to assemble the movable plate body 30 and the coil unit 40 of the mover 20, the through hole 42a is drilled in the core 42 of the coil unit 40, and then the core 42 Installation grooves (42b) to the bottom of the process should be processed, there was a hassle to press the fastening block 48 into the processed installation groove (42b).
특히, 설치홈(42b)이 체결블록(48)의 규격에 맞지 않을 경우, 설치홈(42b)을 재가공해야 하는 문제점이 있었다. 이같은 문제점은 작업시간을 지연시키고, 많은 노동력이 필요로 하여 작업효율과 생산성을 저하시킨다.In particular, when the installation groove 42b does not meet the standard of the fastening block 48, there is a problem that the installation groove 42b must be reworked. This problem delays work time, requires a lot of labor, and reduces work efficiency and productivity.
또한, 종래에는 코어(42) 밑면의 설치홈(42b)에 체결블록(48)을 압입하는 과정에서 절연지(46)가 파손되는 문제점이 있었다. 이같은 문제점은 파손된 절연지 (46) 때문에 코일(44)의 전류가 가동판체(30)와 고정자(10)까지 전달되는 문제를 발생시키며, 따라서 리니어 모터 전체가 절연되지 않는 결과를 초래하여 모터의 성능을 저하시킨다.In addition, conventionally, there is a problem that the insulating paper 46 is damaged in the process of pressing the fastening block 48 into the installation groove 42b on the bottom surface of the core 42. This problem causes a problem that the current of the coil 44 is transferred to the movable plate body 30 and the stator 10 because of the broken insulating paper 46, which results in the entire linear motor not being insulated and thus the performance of the motor. Lowers.
또한, 종래에는 체결블록(48)의 체결구멍(48a)을 탭가공해야 하는 바, 탭가공하는 과정에서 탭 불량이 발생되는 경우, 체결볼트(50)가 체결블록(48)에 나사 체결되지 않는 등, 가동판체(30)와 코일유닛(40)을 조립하기가 매우 어려운 문제점이 있다. 이같은 문제점은 불량 가동자(20)를 양산하는 원인이 된다.In addition, in the related art, the fastening hole 48a of the fastening block 48 has to be tab-bard. If a tab failure occurs in the tapping process, the fastening bolt 50 is not screwed to the fastening block 48. In other words, there is a problem that it is very difficult to assemble the movable plate body 30 and the coil unit 40. Such a problem is a cause of mass-producing the defective mover 20.
