Description

선형모터의 진동자 장치{A device for generating vibration of a linear motor}A device for generating vibration of a linear motor

본 발명은 선형모터의 진동자 장치에 관한 것으로서, 특히 영구자석을 진동자프레임에 취부하는 영구자석 취부구조에 관한 것이다.The present invention relates to a vibrator device of a linear motor, and more particularly to a permanent magnet mounting structure for mounting a permanent magnet to the vibrator frame.

종래 선형압축기모터는 도 1 에 도시된 바와같이 중앙 실린더(3)의 외측에 형성되는 내측철심(1)은 전기강판을 방사형으로 적층하여 원통형으로 만들어 그 내부에 얇은 절연지로 절연처리한 후 코일(4)을 감았으며, 외측철심(2)은 내측철심(1)의 외주면과 일정한 간격을 두고서 내측철심의 바깥쪽에 고정되고, 상기 내측철심(1)과 외측철심(2) 사이에는 진동자(10)가 상하 왕복운동을 하도록 구성하였다.In the conventional linear compressor motor, as shown in FIG. 1, the inner core 1 formed on the outer side of the central cylinder 3 is laminated with electric steel sheets radially, insulated into a cylindrical shape, and insulated with a thin insulating paper therein, and then a coil ( 4) wound, the outer core 2 is fixed to the outside of the inner core at regular intervals with the outer peripheral surface of the inner core (1), the vibrator 10 between the inner core (1) and the outer core (2) It is configured to move up and down reciprocating motion.

그리고 상기 진동자(10)는 도 2 에서와 같이 진동자프레임(12)의 원중심에 지지축(11)을 고정하고, 외측에 다수개의 영구자석(14)을 취부한 후 고정용캔(13)으로 영구자석을 감싸서 운전시에 유동을 방지한다.And the vibrator 10 is fixed to the support shaft 11 at the center of the vibrator frame 12, as shown in Figure 2, after mounting a plurality of permanent magnets 14 on the outside permanently with a fixing can 13 Wrap the magnet to prevent flow during operation.

이 진동자(10)의 지지축(11)은 실린더(3)의 내경면에 지지되어 습동가능한 구조로 되어있고, 진동자프레임(12)에 영구자석(14)이 취부된 부분은 내측철심(1)과 외측철심(2) 사이에 마련된 공간에 위치하여 진동자(10)가 상하 왕복운동을 할 수 있도록 해준다.The support shaft 11 of the vibrator 10 is supported by the inner diameter surface of the cylinder 3 to be slidable, and the portion where the permanent magnet 14 is mounted on the vibrator frame 12 is the inner core 1. Located in the space provided between and the outer iron core (2) allows the vibrator 10 to vertically reciprocate.

상기와 같이 구성된 선형모터의 코일(4)에 교류전원을 인가하면 인가된 전원의 주파수에 상응하는 회수로 진동자가 왕복운동을 하게된다.When the AC power is applied to the coil 4 of the linear motor configured as described above, the vibrator reciprocates with the number of times corresponding to the frequency of the applied power.

그러나 종래 리니어모터는 진동자(10)가 상하로 왕복운동을 할 때, 영구자석(14)의 유동방지를 위해 외측을 감싸고 있는 고정용캔(13)이 완전하게 고정되지 않음으로 인해 진동자로 부터 이탈되는 문제가 있다. 또한 상기의 문제를 해결하기 위해 고정용 캔의 양 끝단부를 구부리게 되면 영구자석이 깨어지는 심각한 문제를 일으키게 된다.However, in the conventional linear motor, when the vibrator 10 reciprocates up and down, the fixing can 13 surrounding the outside for preventing the flow of the permanent magnet 14 is not completely fixed and is separated from the vibrator. there is a problem. In addition, bending both ends of the fixing can to solve the above problems will cause a serious problem that the permanent magnet is broken.

그리고 고정용캔은 영구자석의 외주면을 감싼후 용접을 해야 하므로 작업성이 좋지 않고 용접후의 돌출부는 진동자의 원활한 왕복운동을 저해하는 문제점이 있었다.In addition, since the fixing can has to be welded after wrapping the outer circumferential surface of the permanent magnet, workability is poor and the protrusion after welding has a problem of inhibiting smooth reciprocation of the vibrator.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 진동자프레임의 끝단부를 외경방향으로 꺽어서 영구자석의 일측을 감싸도록 하고, 영구자석의 타측은 고정용링에 의해 지지되도록 구성함으로서, 영구자석과 고정용캔의 위치이탈을 방지하도록 하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, to wrap the end of the vibrator frame in the outer diameter direction to surround one side of the permanent magnet, the other side of the permanent magnet is configured to be supported by the fixing ring By doing so, the purpose is to prevent the positional deviation of the permanent magnet and the fixing can.

본 발명을 도 6 내지 도 8 을 참조하여 이하에서 상세히 설명한다.The invention is described in detail below with reference to FIGS. 6 to 8.

먼저 본 발명 진동자(100)의 구성을 살펴보면 도 8 에 나타낸 바와같이 영구자석(104)의 유동방지를 위해 고정용캔(103)은 양단을 내경방향으로 구부려 형성하였으며, 진동자프레임(102)의 끝단부를 외경방향으로 꺽어서 영구자석(104)의 일측을 지지하도록 구성하고, 상기 영구자석(104)의 타측에는 고정용링(105)을 고정용캔(103)의 일측에 지지되고 진동자프레임(102)의 외주면에 접하도록 구성하였다.Looking at the configuration of the first vibrator 100 of the present invention as shown in Figure 8 to prevent the flow of the permanent magnet 104 is fixed can 103 was formed by bending both ends in the inner diameter direction, the end of the vibrator frame 102 It is configured to support one side of the permanent magnet 104 by bending in the outer diameter direction, the other side of the permanent magnet 104 is supported by the fixing ring 105 on one side of the fixing can 103 and the outer peripheral surface of the vibrator frame 102 It was configured to contact.

도면중 미설명 부호 101 은 지지축을 나타낸다.In the figure, reference numeral 101 denotes a support shaft.

이와같이 구성된 진동자의 영구자석 취부공정을 살펴보면 다음과 같다.Looking at the permanent magnet mounting process of the vibrator configured as described above are as follows.

진동자프레임(102)에 영구자석(104)을 취부하고, 고정용링(105)을 끼운후 고정용 캔(103)을 씌워서 영구자석(104)과 고정용링(105)의 이탈을 방지한다. 그리고 고정용캔(103)의 다른 한쪽을 진동자프레임(102)의 꺽여진 끝단과 접촉되도록 컬링(curling)작업을 한다.The permanent magnet 104 is mounted on the vibrator frame 102, and the fixing ring 105 is fitted to cover the fixing can 103 to prevent the permanent magnet 104 and the fixing ring 105 from being separated. The other side of the fixing can 103 is curled to be in contact with the bent end of the vibrator frame 102.

이때, 진동자프레임(102)의 꺽여진 부분과 고정용링(105)이 영구자석(104)의 양단을 보호하고 있기 때문에 영구자석(104)이 깨어지는 것을 방지할 수 있다.At this time, since the bent portion of the vibrator frame 102 and the fixing ring 105 protect both ends of the permanent magnet 104, the permanent magnet 104 can be prevented from being broken.

이와같이 견고하게 결속된 진동자는(100) 왕복운동시에도 캔(103)이나 영구자석(104)의 이탈현상이 없어지고, 고정용 캔(103)의 용접작업이 없어지므로 인해 작업이 간편해 지고, 진동자의 운동을 방해하는 요소도 사라지게 된다.The vibrator, which is firmly bound in this manner, is eliminated from the can 103 or the permanent magnet 104 even during the reciprocating motion of 100, and the welding operation of the fixing can 103 is eliminated, thereby simplifying the work and the vibrator. Disrupting the movement of the elements will also disappear.

이상 설명한 바와같이 본 발명의 영구자석 취부구조는 진동자의 운전시 영구자석과 고정용캔의 위치이탈을 방지해주고, 취부작업을 간단히 하여 작업효율을 향상시키는 효과가 있다.As described above, the permanent magnet mounting structure of the present invention prevents the positional deviation of the permanent magnet and the fixing can during operation of the vibrator, and has an effect of improving the work efficiency by simplifying the mounting work.
