Description
本発明は、無線通信機器の呼び出し等の機能を付与する振動モータ及び振動モータの製造方法に関する。 The present invention relates to a vibration motor that provides a function such as calling a wireless communication device and a method of manufacturing the vibration motor.
特許文献１には、偏心ウエイトの回転軸挿入溝にモータの回転軸を圧入して偏心ウエイトを取付けることが開示されている。 Patent Document 1 discloses that an eccentric weight is attached by press-fitting a rotating shaft of a motor into a rotating shaft insertion groove of an eccentric weight.
この特許文献１の技術では、回転軸の側面に周方向の凹部を形成し、偏心ウエイトの回転軸挿入溝は溝開口の幅を回転軸の径よりも小さくすると共に回転軸挿入溝の内壁に凸部を形成して、回転軸挿入溝に回転軸を圧入することにより、回転軸の凹部に回転軸挿入溝の凸部を係合することが開示されている。 In the technique of Patent Document 1, a circumferential concave portion is formed on the side surface of the rotation shaft, and the rotation shaft insertion groove of the eccentric weight makes the width of the groove opening smaller than the diameter of the rotation shaft, and on the inner wall of the rotation shaft insertion groove. It is disclosed that a convex portion is formed and a rotary shaft is press-fitted into the rotary shaft insertion groove to engage the convex portion of the rotary shaft insertion groove with the concave portion of the rotary shaft.
また、特許文献２には、偏心ウエイトの回転軸挿入溝の両側に各々かしめ壁部を形成して、かしめ壁部を押し潰すことにより、回転軸をかしめ止めすることが開示されている。 Patent Document 2 discloses that a caulking wall portion is formed on both sides of a rotating shaft insertion groove of an eccentric weight, and the caulking wall portion is crushed to thereby caulk the rotating shaft.
しかし、特許文献１の技術では、製造が困難な上、回転軸を偏心ウエイトの回転軸挿入溝の開口から溝内に圧入しているだけであるから、回転軸の側面と回転軸挿入溝の内面との圧着が充分でない為、回転軸の回転方向に滑りが生じて回転軸が偏心ウエイトに対して空回りしてしまうという問題がある。 However, the technique of Patent Document 1 is difficult to manufacture, and the rotation shaft is only press-fitted into the groove from the opening of the rotation shaft insertion groove of the eccentric weight. Since the pressure contact with the inner surface is not sufficient, there is a problem that slip occurs in the rotation direction of the rotation shaft, causing the rotation shaft to idle with respect to the eccentric weight.
特許文献２の技術では、回転軸の側壁と回転軸挿入溝の内面との圧着により固定強度を高めることができるが、かしめによる固定強度には限界があった。特に、偏心ウエイトに対する回転軸の引き抜き強度に限界があった。 In the technique of Patent Document 2, the fixing strength can be increased by pressing the side wall of the rotating shaft and the inner surface of the rotating shaft insertion groove, but the fixing strength by caulking has a limit. In particular, there was a limit to the pulling strength of the rotating shaft against the eccentric weight.
そこで、本発明は、回転軸と偏心ウエイトとの固定強度が高く且つ製造が容易な振動モータ及び振動モータの提供を目的とする。 Accordingly, an object of the present invention is to provide a vibration motor and a vibration motor that have a high fixing strength between a rotating shaft and an eccentric weight and are easy to manufacture.
請求項１に記載の発明は、モータの回転軸に固定した偏心ウエイトを回転軸と共に回転させることにより、振動を発生させる振動モータにおいて、回転軸の側面には切除又はレーザ光の照射により凹面を粗面にした凹部が形成してあり、偏心ウエイトには回転軸挿入溝と挿入溝の両側に設けたかしめ壁部が形成してあり、偏心ウエイトの回転軸挿入溝内に回転軸を配置してかしめ壁部をかしめにより押し潰すことにより、塑性変形したかしめ壁部の一部が回転軸側面の凹面に食い込んでいることを特徴とする。 According to the first aspect of the present invention, in the vibration motor that generates vibration by rotating the eccentric weight fixed to the rotation shaft of the motor together with the rotation shaft, a concave surface is formed on the side surface of the rotation shaft by excision or irradiation with laser light. A roughened recess is formed, and the eccentric weight is formed with a rotation shaft insertion groove and a caulking wall portion provided on both sides of the insertion groove, and the rotation shaft is disposed in the rotation shaft insertion groove of the eccentric weight. By caulking the caulking wall portion by caulking, a part of the caulking wall portion that has been plastically deformed bites into the concave surface on the side surface of the rotating shaft.
請求項２に記載の発明は、モータの回転軸に固定した偏心ウエイトを回転軸と共に回転させることにより、振動を発生させる振動モータの製造方法において、偏心ウエイトには回転軸挿入溝と挿入溝の両側に設けたかしめ壁部が形成してあり、回転軸の側面には切除又はレーザ光の照射により凹面を粗面にした凹部を形成し、偏心ウエイトの回転軸挿入溝内に回転軸を配置してかしめ壁部をかしめにより押し潰すことにより、かしめ壁部を塑性変形して回転軸側面の凹面に食い込ませることを特徴とする。 According to a second aspect of the present invention, in the method of manufacturing a vibration motor in which the eccentric weight fixed to the rotation shaft of the motor is rotated together with the rotation shaft to generate vibration, the eccentric weight includes a rotation shaft insertion groove and an insertion groove. A caulking wall is provided on both sides, and a concave part with a roughened concave surface is formed on the side of the rotary shaft by cutting or laser light irradiation , and the rotary shaft is placed in the rotary shaft insertion groove of the eccentric weight Then, the caulking wall portion is crushed by caulking, so that the caulking wall portion is plastically deformed and bites into the concave surface on the side surface of the rotating shaft.
請求項１に記載の発明によれば、回転軸には側面に凹部を形成しているので、かしめ壁部をかしめたときに、かしめ壁部が塑性変形して凹部に食い込み、回転軸と偏心ウエイトとの圧着面積を広くでき、固定強度を高めることができる。特に、回転軸と偏心ウエイトのせん断強さを利用した接合ができ、固定強度が高い。また、かしめにより回転軸の凹部にかしめ壁部が塑性変形して圧着するので、凹部における接合強度が高く、回転軸の回転方向及び引き抜き方向（回転軸の軸線方向）のいずれの強度も高くできる。 According to the first aspect of the present invention, since the concave portion is formed on the side surface of the rotating shaft, when the caulking wall portion is caulked, the caulking wall portion is plastically deformed and bites into the concave portion, and the rotating shaft and the eccentric shaft are eccentric. The area of pressure contact with the weight can be increased, and the fixing strength can be increased. In particular, the joining using the shear strength of the rotating shaft and the eccentric weight can be performed, and the fixing strength is high. Further, since the caulking wall portion is plastically deformed and crimped to the concave portion of the rotating shaft by caulking, the bonding strength in the concave portion is high, and both the strength of the rotating shaft in the rotational direction and the drawing direction (axial direction of the rotating shaft) can be increased. .
回転軸の側面に予め凹部を形成してかしめ止めするだけであるから、製造が容易である。 Manufacture is easy because it is only necessary to form a concave portion in advance on the side surface of the rotating shaft and stop it.
回転軸の側面は切刃により切除又はレーザ光を照射することにより粗面としているので、かしめ壁部が回転軸の粗面に塑性変形して接合でき、凹部における接合強度を更に高めることができる。また、回転軸に切刃を当てたりレーザ光を照射することにより、容易に形成できる。 The side surface of the rotational shafts is Riaramen by the irradiation with ablation or laser light by the cutting edge, can joint caulking wall is plastically deformed into the rough surface of the rotary shaft, further increasing the bonding strength in the recess Can do. Further, it can be easily formed by applying a cutting blade to the rotating shaft or irradiating with a laser beam.
凹部をレーザ光の照射により形成する場合には、切刃で形成する場合に比較して切除面を粗くでき且つ非接触により凹部を形成できるので形状の自由度が高い。また、切除面が粗いので、かしめによる接合強度を高めることができる。 In the case where the concave portion is formed by irradiation with laser light, the cut surface can be roughened and the concave portion can be formed in a non-contact manner compared to the case where the concave portion is formed with a cutting blade, so that the degree of freedom in shape is high. Moreover, since the cut surface is rough, the bonding strength by caulking can be increased.
請求項２に記載の発明によれば、請求項１に記載の発明と同様の作用効果を奏することができる。 According to the invention described in claim 2 , the same effect as that of the invention described in claim 1 can be obtained.
以下に、添付図面を参照して本発明の実施の形態を説明する。図１は、本実施の形態に係る回転軸と偏心ウエイトとの取付状態を示す振動モータの斜視図であり、図２は実施例１における図１のＡ−Ａ断面図であり、図３は実施例２における図１のＡ―Ａ断面図であり、図４は図１に示す振動モータの製造方法を説明する図であり、偏心ウエイトに回転軸を挿入した状態を示す斜視図である。図５は図３のＢ―Ｂ断面図であり、図６は回転軸を拡大して示す斜視図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a vibration motor showing an attachment state of a rotating shaft and an eccentric weight according to the present embodiment, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 in Example 1, and FIG. FIG. 4 is a cross-sectional view taken along the line AA of FIG. 1 in the second embodiment, and FIG. 4 is a diagram for explaining the method of manufacturing the vibration motor shown in FIG. 1 and is a perspective view showing a state where a rotating shaft is inserted into an eccentric weight. 5 is a cross-sectional view taken along the line BB of FIG. 3, and FIG. 6 is a perspective view showing an enlarged rotation shaft.
本実施の形態に係る振動モータ１は、携帯電話に組み込まれて、着信時等に振動する振動モータである。この振動モータ１は、モータ本体２の回転軸３と、回転軸３に固定した偏心ウエイト５とを備えている。本実施の形態では、以下に実施例１と実施例２との場合を説明するが、実施例１と実施例２とは凹部７の形状及び構造が異なるものである。 The vibration motor 1 according to the present embodiment is a vibration motor that is incorporated in a mobile phone and vibrates when an incoming call is received. The vibration motor 1 includes a rotating shaft 3 of a motor body 2 and an eccentric weight 5 fixed to the rotating shaft 3. In the present embodiment, the case of Example 1 and Example 2 will be described below. However, Example 1 and Example 2 are different in the shape and structure of the recess 7.
（実施例１）
回転軸３には、偏心ウエイト５との取付部に凹部７が形成されている。凹部７は回転軸３の側面に形成した溝条であり、本実施の形態では、側面の周方向に沿って全周に亘って形成されている。この溝条は、回転軸３の先端３ａから間隔Ｍ（約１ｍｍ）を開けた位置に回転軸製造時に回転軸に切刃を当てることにより形成されている。
(Example 1)
A concave portion 7 is formed in the rotating shaft 3 at the attachment portion with the eccentric weight 5. The recess 7 is a groove formed on the side surface of the rotating shaft 3 and is formed over the entire circumference along the circumferential direction of the side surface in the present embodiment. The groove is formed by applying a cutting edge to the rotary shaft at the time when the rotary shaft is manufactured at a position spaced apart from the tip 3a of the rotary shaft 3 by an interval M (about 1 mm).
回転軸３の軸径Ｗは約０．６ｍｍであり、凹部７の溝条は、溝幅Ｔは０．２ｍｍ〜１．０ｍｍであり、深さＨが０．０２５ｍｍ〜０．０５ｍｍである（図２参照）。 The shaft diameter W of the rotary shaft 3 is about 0.6 mm, and the groove of the recess 7 has a groove width T of 0.2 mm to 1.0 mm and a depth H of 0.025 mm to 0.05 mm ( (See FIG. 2).
回転軸３の周面には表面加工が施されて滑らかになっているが、凹部７の溝底７ａと溝壁７ｂは、回転軸３の地肌が露出されて粗くなっている。特に、本実施の形態では、回転軸製造時に回転軸に切刃を当てることにより表面を切除しているので、凹部７の溝底７ａと溝壁７ｂの表面は、未加工面となり切除面を粗くすることができる。 Although the peripheral surface of the rotating shaft 3 is smoothed by surface processing, the groove bottom 7a and the groove wall 7b of the recess 7 are roughened by exposing the ground of the rotating shaft 3. In particular, in this embodiment, since the surface is cut by applying a cutting blade to the rotary shaft when the rotary shaft is manufactured, the surfaces of the groove bottom 7a and the groove wall 7b of the recess 7 become unprocessed surfaces and the cut surfaces are changed. It can be roughened.
（実施例２）
回転軸３には、偏心ウエイト５との取付部に凹部７が形成されている。凹部７は回転軸３の側面に形成した溝条であり、本実施の形態では、全周の略半分程度亘って形成されている。この溝条は、回転軸３の先端３ａから間隔Ｍ（約１ｍｍ）に亘り、レーザ光を照射することにより複数形成されている。
(Example 2)
A concave portion 7 is formed in the rotating shaft 3 at the attachment portion with the eccentric weight 5. The recess 7 is a groove formed on the side surface of the rotary shaft 3 and is formed over approximately half of the entire circumference in the present embodiment. A plurality of the grooves are formed by irradiating the laser beam over the interval M (about 1 mm) from the tip 3a of the rotating shaft 3.
回転軸３の軸径Ｗは約０．６ｍｍであり、凹部７の溝条は、溝幅Ｔは約０．０４ｍｍであり、深さＨが約０．０２ｍｍである（図２参照）。 The shaft diameter W of the rotating shaft 3 is about 0.6 mm, and the groove of the recess 7 has a groove width T of about 0.04 mm and a depth H of about 0.02 mm (see FIG. 2).
回転軸３の周面には表面加工が施されて滑らかになっているが、凹部７は、回転軸３の地肌が露出されて粗くなっている。特に、本実施の形態では、回転軸製造後に回転軸にレーザ光を照射することにより表面を切除し溝条を複数形成しているので、凹部７表面は、未加工面となり切除面を粗くすることができる。 The peripheral surface of the rotating shaft 3 is smoothed by surface processing, but the concave portion 7 is rough because the background of the rotating shaft 3 is exposed. In particular, in this embodiment, since the surface is cut off by irradiating the rotary shaft with laser light after the rotary shaft is manufactured and a plurality of grooves are formed, the surface of the concave portion 7 becomes an unprocessed surface and the cut surface is roughened. be able to.
偏心ウエイト５は、円柱を略半分に割った形状になっており、平面部９に回転軸の取付部１１が形成されている。図４に示すように、回転軸取付部１１は、回転軸挿入溝１３と回転軸挿入溝１３の両側に各々立設したかしめ壁部１５ａ、１５ｂとで構成されており、かしめ壁部１５ａ、１５ｂは、回転軸挿入溝１３に沿って設けてある。 The eccentric weight 5 has a shape obtained by dividing a column into approximately halves, and a mounting portion 11 of a rotating shaft is formed on the flat surface portion 9. As shown in FIG. 4, the rotating shaft mounting portion 11 includes a rotating shaft insertion groove 13 and caulking wall portions 15 a and 15 b erected on both sides of the rotating shaft insertion groove 13, respectively. 15 b is provided along the rotation shaft insertion groove 13.
かしめ壁部１５ａ、１５ａ間の幅及び回転軸取付溝の幅Ｓ（図５参照）は、回転軸３の軸径Ｗと略同じ寸法になっている。 The width between the caulking wall portions 15a and 15a and the width S (see FIG. 5) of the rotating shaft mounting groove are substantially the same as the shaft diameter W of the rotating shaft 3.
次に、回転軸３を偏心ウエイト５に取付ける方法、作用及び効果について説明する。図４に示すように、回転軸取付溝１３内に回転軸３を挿入し、かしめ壁部１５ａ、１５ｂを上方からかしめ手段１７で押し潰す。これにより、図１及び図２、図３に示すように、かしめ壁部１５ａ、１５ｂが塑性変形して、回転軸３に圧着する。 Next, a method, operation, and effect of attaching the rotating shaft 3 to the eccentric weight 5 will be described. As shown in FIG. 4, the rotary shaft 3 is inserted into the rotary shaft mounting groove 13, and the caulking wall portions 15 a and 15 b are crushed by the caulking means 17 from above. Thereby, as shown in FIGS. 1, 2, and 3, the caulking wall portions 15 a and 15 b are plastically deformed and pressure-bonded to the rotating shaft 3.
塑性変形したかしめ壁部１５ａ、１５ｂは、回転軸３の側面に圧着すると共に、回転軸３の側面に形成されている凹部７に食い込む。かしめ壁部１５ａ、１５ｂが塑性変形して凹部７に食い込むと、更に、凹部７の溝底７ａや溝壁７ｂに露出した粗面に流動するようにして接合することができる。 The caulking wall portions 15 a and 15 b which have been plastically deformed are pressed against the side surface of the rotating shaft 3 and bite into the recesses 7 formed on the side surface of the rotating shaft 3. When the caulking wall portions 15 a and 15 b are plastically deformed and bite into the recess 7, the caulking wall portions 15 a and 15 b can be joined so as to flow to the rough surface exposed to the groove bottom 7 a and the groove wall 7 b of the recess 7.
本実施の形態によれば、回転軸３には側面に凹部７を形成しているので、かしめ壁部１５ａ、１５ｂをかしめたときに、かしめ壁部１５ａ、１５ｂが塑性変形して凹部７に食い込み、回転軸３と偏心ウエイト５との圧着面積を広くできるので、固定強度を高めることができる。また、回転軸３と偏心ウエイト５のせん断強さを利用した接合ができ、固定強度が高い。 According to the present embodiment, since the concave portion 7 is formed on the side surface of the rotary shaft 3, when the caulking wall portions 15 a and 15 b are caulked, the caulking wall portions 15 a and 15 b are plastically deformed to form the concave portion 7. Since the biting area between the rotary shaft 3 and the eccentric weight 5 can be increased, the fixing strength can be increased. Moreover, the joining using the shear strength of the rotating shaft 3 and the eccentric weight 5 can be performed, and the fixing strength is high.
特に、かしめにより回転軸３の凹部７にかしめ壁部１５ａ、１５ｂが塑性変形して圧着するので、凹部７における接合強度が高く、回転軸３の回転方向及び引き抜き方向のいずれの強度も高めることができる。 In particular, since the caulking wall portions 15a and 15b are plastically deformed and crimped to the concave portion 7 of the rotating shaft 3 by caulking, the bonding strength in the concave portion 7 is high, and both the strength of the rotating shaft 3 in the rotational direction and the drawing direction are increased. Can do.
凹部７は回転軸３の周方向に形成した溝条としているので、かしめ壁部１５ａ、１５ｂが塑性変形して入り込んだ部分と凹凸係合するので、回転軸３の引き抜き方向の強度が高い。 Since the recess 7 is a groove formed in the circumferential direction of the rotating shaft 3, the caulking wall portions 15a and 15b are engaged with the concave and convex portions by plastic deformation, so that the strength of the rotating shaft 3 in the pulling direction is high.
実施例１に係る回転軸３の凹部７は、回転軸製造時に回転軸に切刃を当てることにより表面を切除して粗面としているので、かしめ壁部１５ａ、１５ｂとの食い込みによる接合強度が高い。 Since the concave portion 7 of the rotary shaft 3 according to the first embodiment is roughened by cutting the surface by applying a cutting blade to the rotary shaft at the time of manufacturing the rotary shaft, the bonding strength due to the biting into the caulking wall portions 15a and 15b is high. high.
実施例１に係る回転軸の凹部７は、回転軸製造時に回転軸に切刃を当てることにより容易に製造でき、製造効率が良い。実施例２に係る回転軸の凹部７は、レーザ光を照射して切除しているので、切刃よりも切除面を粗くできると共に非接触に凹部７を形成できるので、形状の自由度が高い。 The concave portion 7 of the rotating shaft according to the first embodiment can be easily manufactured by applying a cutting blade to the rotating shaft when manufacturing the rotating shaft, and the manufacturing efficiency is good. Since the concave portion 7 of the rotating shaft according to the second embodiment is excised by irradiating with laser light, the excised surface can be made rougher than the cutting edge and the concave portion 7 can be formed in a non-contact manner. .
本発明は、上述した実施の形態に限らず、本発明の要旨を逸脱しない範囲で種々変形可能である。 The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
例えば、凹部７の溝条は、実施例１において、一条に限らず、複数条形成するものであってもよいし、回転軸の全周に亘って形成することなく、全周の略半分程度に亘って形成するものであってもよい。また、実施例２において、凹部７の溝条は、回転軸の全周に亘って形成するものであってもよいし、一条であってもよい。 For example, the groove 7 of the recess 7 is not limited to a single line in the first embodiment, and a plurality of grooves may be formed, or approximately half of the entire circumference without being formed over the entire circumference of the rotating shaft. It may be formed over the entire area. Moreover, in Example 2, the groove | channel of the recessed part 7 may be formed over the perimeter of a rotating shaft, and a single line | wire may be sufficient as it.
凹部７は、図７に示すように、ローレット（網目条）に形成してもよい。また、凹部７は、図８に示すように、回転軸の周面に点状に形成するものであってもよい。 As shown in FIG. 7, the recess 7 may be formed in a knurl (mesh). Moreover, the recessed part 7 may be formed in dot shape on the surrounding surface of a rotating shaft, as shown in FIG.
かしめ壁部１５ａ、１５ｂは、偏心ウエイト５に形成した回転軸挿入溝１３に沿って設けることに限らず、回転軸挿入溝１３の長手方向に間隔を開けて設けてもよいし、長手方向中央部のみに設けてもよい。 The caulking wall portions 15a and 15b are not limited to be provided along the rotation shaft insertion groove 13 formed in the eccentric weight 5, but may be provided at intervals in the longitudinal direction of the rotation shaft insertion groove 13 or in the center in the longitudinal direction.
