Description

本発明は、モータの組み立てライン等に併設可能なコギングトルク測定が自動的に行える小型モータ用コギングトルク測定支持装置に関するものである。   The present invention relates to a cogging torque measurement support device for a small motor that can automatically perform cogging torque measurement that can be installed in a motor assembly line or the like.

近時、駆動源となるモータも小型化が一段と進み、家電製品，各種事務機器を初めとし自動車等を含む大型機械（装置）に至るまで広い分野に用いられ、且つ更なる需要の高まりを見るものである。勿論、モータ自体の性能も高性能化，高効率化や小型・軽量化並びに低振動，低騒音化などにかかわる対策も図られる。   Recently, motors that serve as driving sources have been further reduced in size, and are used in a wide range of fields from home appliances, various office equipment to large machines (equipment) including automobiles, etc. Is. Of course, the motor itself can be improved in terms of performance, efficiency, size, weight, vibration and noise.

このため、このモータ製品の提供にあっては各種の検査項目チェックを受けるものである。だが、現在用いられるモータにはトルクムラと呼ばれる問題点が依然と存在する。例えば、コイル巻き溝に起因する突極構造ではどうしてもコギングを伴うため、このコギング現象がモータ出力に悪い影響を与えるものになる。従って、トルクムラや回転ムラ特性が問題になるので、モータ軸のコギングトルク測定が必要になる。   For this reason, in order to provide this motor product, various inspection items are checked. However, there is still a problem called torque unevenness in motors currently used. For example, since the salient pole structure caused by the coil winding groove always involves cogging, this cogging phenomenon adversely affects the motor output. Accordingly, torque unevenness and rotation unevenness characteristics become a problem, and therefore, measurement of the cogging torque of the motor shaft is necessary.

ここで、従来知られているコギングトルク測定の支持装置としては、例えば、所定の測定台（測定装置）の側壁面にあって、この左右側に２本の平行な垂直軸を配し、該両垂直軸に両端が昇降自在に案内される上下一対の挾持型把持駒（モータ取付金具）を取付け、
該両把持駒間に所定の被測定モータを横向きにセットして固定すると共に、このモータ軸を測定台側の回転軸にカップリングさせる構成を取っている。このため、被測定モータのセット作業は、一般には手作業にて行う。先ず上側の把持駒を固定ネジを緩め両垂直軸に沿って昇降させ、一対の把持駒間にモータを挿入するセット間隙を設け、該セット間隙中に横向き姿勢（モータ軸を横向きに）の被測定モータを入れ、その後上側の把持駒を下げ被測定モータを狭接し再度固定ネジを締める作業をする。このとき、横向きモータ軸と測定台側壁面に有するセンサー軸とのカップリング接続をも行わねばならない。 Here, as a conventionally known cogging torque measurement support device, for example, on a side wall surface of a predetermined measurement table (measurement device), two parallel vertical axes are arranged on the left and right sides, and Attach a pair of upper and lower gripping pieces (motor mounting brackets) whose both ends are guided up and down on both vertical axes,
A predetermined motor to be measured is set and fixed horizontally between the gripping pieces, and the motor shaft is coupled to the rotating shaft on the measurement table side. For this reason, the setting work of the motor to be measured is generally performed manually. First, the upper gripping piece is lifted and lowered along the two vertical axes by loosening the fixing screws, and a set gap for inserting the motor is provided between the pair of gripping pieces, and a lateral posture (motor shaft sideways) is covered in the set gap. Insert the measuring motor, then lower the upper gripping piece and close the motor to be measured, and tighten the fixing screw again. At this time, the coupling connection between the lateral motor shaft and the sensor shaft on the side wall of the measuring table must also be performed.

この横向きセンサー軸でコギングトルク測定をするに際する支持装置は、必然的に被測定モータも横向き姿勢でセットせねばならず、且つ該モータ軸とセンサー軸が同一線上になるセット調整も要する。更に、この被測定モータを所定位置に保持した状態で、上方に予め摺動後退した上側把持駒を降下さて下側把持駒とで挾持させ、且つ該把持駒両端に装着の固定ネジを締めねばならず面倒な作業になる。しかも、モータ軸を横向きに配す支持では、どうしてもトルク測定器側とのカップリングに起因する偏心の点が問題になり、精度のよい測定は難しい。また、一対の挾持型把持駒の摺動，固定等の操作も手作業にてその都度行うため、量産に適すコギングトルク測定の支持装置には不向きである。   The support device for measuring the cogging torque with the lateral sensor shaft inevitably requires the motor to be measured to be set in the lateral orientation, and also requires set adjustment so that the motor shaft and the sensor shaft are on the same line. Furthermore, with the motor to be measured held in a predetermined position, the upper gripping piece that has been slid upward in advance is lowered and held by the lower gripping piece, and the fixing screws attached to both ends of the gripping piece are tightened. It becomes a troublesome work. Moreover, in the support in which the motor shaft is disposed sideways, the eccentricity caused by the coupling with the torque measuring instrument side inevitably becomes a problem, and accurate measurement is difficult. In addition, since operations such as sliding and fixing of the pair of gripping gripping pieces are performed manually each time, they are not suitable for a cogging torque measurement support device suitable for mass production.

なお、コギングトルク測定装置としての支持方式を、モータ軸を偏心が受けにくい縦向き配置（垂直）にしたタイプも知られている。例えば、特開平５−１４９８０３号公報のものがある。
特開平５−１４９８０３号公報 There is also known a type in which a support system as a cogging torque measuring device is arranged in a vertical direction (vertical) in which the motor shaft is less susceptible to eccentricity. For example, there exists a thing of Unexamined-Japanese-Patent No. 5-149803.
JP-A-5-149803

しかし、前記公報記載のコギングトルク測定装置は、図５に示す様に被測定モータのセット位置を縦向きとしているが、この場合被測定モータａのセット作業として、モータ下部のステータ部を公知の把持手段であるチャッキング装置ｂで自動保持を行っても、該被測定モータ上端に突出のモータ軸ｃに対する測定用プーリｄの取付けは、単に該プーリを嵌めるだけの作業では済まない。即ち、このプーリｄにはトルク検出手段の一部である紐ｅが掛けられていて、該紐ｅの両端を互いに引き合うように展張せねばならず、且つ紐ｅの両端を夫々ロードセルｆ，ｆに導く必要もあり複雑な扱いになる。   However, in the cogging torque measuring device described in the above publication, the set position of the motor to be measured is set vertically as shown in FIG. 5. In this case, as a setting operation of the motor to be measured a, a stator portion under the motor is publicly known. Even if the chucking device b, which is a gripping means, is automatically held, the attachment of the measurement pulley d to the motor shaft c protruding at the upper end of the motor to be measured does not have to be performed simply by fitting the pulley. That is, a string e which is a part of the torque detecting means is hung on the pulley d, both ends of the string e must be stretched so as to attract each other, and both ends of the string e are respectively connected to the load cells f and f. It is necessary to lead to a complicated treatment.

この縦向き被測定モータａのステータ部を下方のチャッキング装置ｂで受けると云うことは、モータの全加重を受ける支持になりセット保持の確実性は出るが、被測定モータ上端に突出のモータ軸ｃに対するプーリｄのセット作業は、該プーリｄに紐ｅを巻き付ける関係上、単なる軸嵌合の接続だけでは対処しえない。また、被測定モータのセットに際し該被測定モータを一旦手で掴み縦向きに変えながらステータ部をチャッキング装置に臨ませ、その後被測定モータ上端のモータ軸に、別途移行させたプーリを適宜装着する段階的な取り扱いになり、手間の掛かる面倒な仕事となる。勿論、このプーリに巻付けたトルク検出手段の一部である紐をロードセル側に引き合う作業も施さねばならない。   The fact that the stator portion of the vertically measured motor a is received by the lower chucking device b is a support that receives the full load of the motor, and there is a certainty of holding the set, but the motor that protrudes from the upper end of the measured motor The setting operation of the pulley d with respect to the shaft c cannot be dealt with by simply connecting the shaft fitting because the string e is wound around the pulley d. Also, when setting the motor to be measured, hold the motor to be measured once by hand and change the vertical direction so that the stator part faces the chucking device, and then a separate pulley is attached to the motor shaft at the upper end of the motor to be measured. It becomes a gradual handling, and it becomes a troublesome work that takes time. Of course, it is also necessary to perform an operation of drawing a string, which is a part of the torque detecting means wound around the pulley, toward the load cell.

即ち、被測定モータａのモータ軸ｃに対するプーリｄの取付けに際し、動ひずみ測定器ｇ，ｇで固有の較正係数，出力特性を補正するためのロードセルｆ，ｆに繋がる紐ｅが巻き付いているので、セット作業に熟練を要する。仮に、被測定モータのステータ部とチャッキング装置が自動係合されたとしても、被測定モータ全体としては前記紐ｅ等の処理に問題を残しセット作業の自動化までに至らない。   That is, when the pulley d is attached to the motor shaft c of the motor a to be measured, the string e connected to the load cells f and f for correcting the inherent calibration coefficient and output characteristics by the dynamic strain measuring instruments g and g is wound. , Skill is required for set work. Even if the stator portion of the motor to be measured and the chucking device are automatically engaged, the whole motor to be measured leaves a problem in the processing of the string e or the like and does not lead to the automation of the setting operation.

このことは、従来型のコギングトルク測定装置を、例えば被測定モータの組み立てラインに併設の配置とし、連続して搬出される被測定モータを連続的に該コギングトルク測定装置側に取り込みしたとしても、このコギングトルク測定装置でのセットを手作業には手間が掛かる（時間が掛かる）ので、現状ではコギングトルク測定の自動化は望めない。このため、この種のコギングトルク測定の検査能率のアップとしては、所定の検査装置（コギングトルク測定装置）を多数配設し、個々の装置ごとに作業員を置き所謂人海戦術をもって検査を行うよりほかなかった。なお、同図中、ｈはエンコーダよりなる相対位置検出手段、ｉは測定用コンピュータで、ｊはプリンターを示す。   This is because even if a conventional cogging torque measuring device is arranged in the assembly line of the motor to be measured, for example, and the motor to be continuously carried out is continuously taken into the cogging torque measuring device side. Since setting with this cogging torque measuring device takes time (many time) in manual work, automation of cogging torque measurement cannot be expected at present. For this reason, in order to increase the inspection efficiency of this type of cogging torque measurement, a large number of predetermined inspection devices (cogging torque measurement devices) are arranged, and workers are assigned to the individual devices to perform inspections using so-called human naval tactics. There was nothing else. In the figure, h is a relative position detecting means comprising an encoder, i is a measuring computer, and j is a printer.

本発明は上記実情に鑑み、測定位置での下向き搬入の被測定モータのモータ軸を受けるチャック機構を備えた下部スピンドルと該被測定モータ上端を受ける上部スピンドルを対向させ、下部スピンドルに縦貫通のロッドの昇降でチャック機構のチャック駒部を開閉させモータ軸を固定し、該下部スピンドルを直接回転させるようにし、上記課題を解決する小型モータ用コギングトルク測定支持装置を提供することを目的としたものである。   In the present invention, in view of the above situation, a lower spindle having a chuck mechanism for receiving a motor shaft of a motor to be measured downward loaded at a measurement position is opposed to an upper spindle for receiving an upper end of the motor to be measured, and the lower spindle is vertically penetrated. An object of the present invention is to provide a cogging torque measuring and supporting device for a small motor that solves the above-mentioned problems by opening and closing the chuck piece of the chuck mechanism by lifting and lowering the rod, fixing the motor shaft, and rotating the lower spindle directly. Is.

本発明は、モータ軸を下向きに縦搬入する被測定モータが臨む測定位置にあって、この上方に該被測定モータ上端を受ける昇降型上部スピンドルと、該上部スピンドルより所定間隔を隔て同軸線上である下方に固定支持体で軸承された前記モータ軸を直接嵌入するチャック機構を上部に形成の下部スピンドルとを対向設置し、前記下部スピンドルの下端にコギングトルク用駆動プーリを取付けると共に、この駆動プーリと下部スピンドルに縦貫通したチャック解除用ロッドを前記チャック機構のチャック駒部に臨ませ、チャック解除用ロッドの下方にロッド昇降用シリンダーを配置し、且つ前記固定支持体より突出する下部スピンドル中間部分に前記チャック駒部の軸部位置に対応の第一のコギングセンサーを装着してなるものである。   The present invention is a measuring position where a motor to be measured vertically loaded with a motor shaft facing downwards, and a lift-type upper spindle for receiving the upper end of the motor to be measured, and a coaxial line at a predetermined interval from the upper spindle. A lower spindle having a chuck mechanism for directly fitting the motor shaft, which is supported by a fixed support below, is formed to face the lower spindle, and a driving pulley for cogging torque is attached to the lower end of the lower spindle. And a lower spindle intermediate portion protruding from the fixed support, with a chuck releasing rod vertically passing through the lower spindle facing the chuck piece of the chuck mechanism, a rod raising / lowering cylinder disposed below the chuck releasing rod And a first cogging sensor corresponding to the position of the shaft of the chuck piece.

また、モータ軸を下向きに縦搬入する被測定モータが臨む測定位置にあって、この上方に該被測定モータ上端を受ける昇降型上部スピンドルと、該上部スピンドルより所定間隔を隔て同軸線上である下方に固定支持体で軸承された前記モータ軸を直接嵌入するチャック機構を上部に形成の下部スピンドルとを対向設置し、前記下部スピンドルの下端にコギングトルク用駆動プーリを取付けると共に、この駆動プーリと下部スピンドルに縦貫通したチャック解除用ロッドを前記チャック機構のチャック駒部に臨ませ、チャック解除用ロッドの下方にロッド昇降用シリンダーを配置し、且つ前記測定位置にセットされた被測定モータのモータ側面位置に、横繰り出しで周接自在となる第二のコギングセンサーを配置してなるものである。   In addition, the upper part of the lift type spindle that receives the upper end of the motor to be measured is located at the measurement position facing the motor to be measured that vertically carries the motor shaft downward, and the lower part that is on the same axis with a predetermined interval from the upper spindle. A chuck mechanism that directly fits the motor shaft that is supported by a fixed support on the lower spindle is formed on the upper side, and a cogging torque drive pulley is attached to the lower end of the lower spindle. A chuck releasing rod vertically penetrating the spindle faces the chuck piece of the chuck mechanism, a rod raising / lowering cylinder is disposed below the chuck releasing rod, and the motor side surface of the measured motor set at the measurement position A second cogging sensor that can be freely circumscribed by lateral extension is arranged at the position.

また、モータ軸を下向きに縦搬入する被測定モータが臨む測定位置にあって、この上方に該被測定モータ上端を受ける昇降型上部スピンドルと、該上部スピンドルより所定間隔を隔て同軸線上である下方に固定支持体で軸承された前記モータ軸を直接嵌入するチャック機構を上部に形成の下部スピンドルとを対向設置し、前記下部スピンドルの下端にコギングトルク用駆動プーリを取付けると共に、この駆動プーリと下部スピンドルに縦貫通したチャック解除用ロッドを前記チャック機構のチャック駒部に臨ませ、チャック解除用ロッドの下方にロッド昇降用シリンダーを配置し、且つ前記固定支持体より突出する下部スピンドル中間部分に前記チャック駒部の軸部位置に対応の第一のコギングセンサーを装着し、また前記測定位置にセットされた被測定モータのモータ側面位置に、横繰り出しで周接自在となる第二のコギングセンサーを配置してなるものである。   In addition, the upper part of the lift type spindle that receives the upper end of the motor to be measured is located at the measurement position facing the motor to be measured that vertically carries the motor shaft downward, and the lower part that is on the same axis with a predetermined interval from the upper spindle. A chuck mechanism that directly fits the motor shaft that is supported by a fixed support on the lower spindle is formed on the upper side, and a cogging torque drive pulley is attached to the lower end of the lower spindle. A chuck releasing rod vertically penetrating the spindle faces the chuck piece of the chuck mechanism, a rod raising / lowering cylinder is disposed below the chuck releasing rod, and the lower spindle intermediate portion protruding from the fixed support body Attach the first cogging sensor corresponding to the shaft position of the chuck piece and set it to the measurement position. The motor side position of the measuring motors, those formed by arranging the second cogging sensor consisting of a horizontal feed freely circumferential tangent.

この場合、第一のコギングセンサーが、大容量用コギングセンサーである。   In this case, the first cogging sensor is a large capacity cogging sensor.

また、第二のコギングセンサーが、小容量用コギングセンサーである。   The second cogging sensor is a small capacity cogging sensor.

更に、チャック機構が、上部中央にスリット付きモータ軸受穴を配し連設下部を支持用軸部とする摺動型チャック駒部と、これに二重嵌合する該チャック駒部口縁の外テーパーを規制する固定内テーパーを上端内側に配す外筒部及び該外筒部とチャック駒部間に緩衝スプリングを介在した構成で、且つ前記チャック駒部端に昇降接衝する前記ロッドでモータ軸受穴が開閉する。   In addition, the chuck mechanism has a slit-type motor bearing hole in the center of the upper part, and a sliding chuck piece part having a continuous lower part as a supporting shaft part, and an outer edge of the chuck piece part edge that is double-fitted to this. A motor with the rod that is configured to have a fixed inner taper that regulates the taper on the inner side of the upper end, and a buffer spring interposed between the outer tube and the chuck piece, and that is in contact with the end of the chuck piece The bearing hole opens and closes.

この様に、小型モータ用コギングトルク測定支持装置は、モータ軸を下向きに縦搬入する被測定モータの測定位置の上方に該モータ上端を受ける上部スピンドルを、測定位置の下方に前記モータ軸が嵌まり込む摺動型チャック駒部を配すチャック機構付きの下部スピンドルを対向設置する構成とし、且つ該下部スピンドルを駆動プーリで回転すると共に、中央に縦貫通したロッド昇降用シリンダーで作動するロッドで前記チャック機構のチャック駒部を昇降自在とし、このチャック駒部の上昇でテーパー規制が解けモータ軸受穴が開くようにしたので、被測定モータが測定位置に達し適宜の搬送把持手段が外れて落下（又は機械的降下）すれば、このとき真下の前記下部スピンドルが上端のチャック駒部に有するモータ軸受穴が予め広がる開放待機しているため、該モータ軸受穴に被測定モータの下向きモータ軸が自動嵌入される。この後、前記ロッドの下降に伴いチャック駒部が緩衝スプリングの弾発をもって下摺動し、モータ軸受穴は外筒部側固定テーパーの規制を受けて閉じモータ軸をきつく挾持の固定となる。このとき、被測定モータ上端には別途降下する上部スピンドルで受け、被測定モータ全体の測定セットとなる。   As described above, the cogging torque measuring and supporting device for a small motor is configured such that the upper spindle that receives the upper end of the motor is fitted above the measurement position of the motor to be measured, and the motor shaft is fitted below the measurement position. A rod with a chuck mechanism that places a sliding chuck piece that fits in, and a lower spindle that rotates with a drive pulley and that is driven by a rod lifting cylinder that runs vertically through the center. Since the chuck piece of the chuck mechanism can be raised and lowered, and the taper restriction is released and the motor bearing hole is opened by raising the chuck piece, the motor to be measured reaches the measurement position, and the appropriate conveyance gripping means comes off and falls. (Or mechanical lowering) at this time, the motor spindle hole that the lower spindle just below has in the chuck piece at the upper end is opened in advance. Because it is waiting, down the motor shaft of the measured motor is automatically fitted into the motor bearing hole. Thereafter, as the rod descends, the chuck piece slides downward with the spring of the buffer spring, the motor bearing hole is closed by the restriction of the outer cylinder side fixed taper, and the motor shaft is fixed tightly. At this time, the upper end of the motor to be measured is received by an upper spindle that is separately lowered to form a measurement set for the entire motor to be measured.

この場合、コギングトルク測定をするコギングセンサーの配置は、下部スピンドルの外周中間位置に配する第一のコギングセンサーと測定位置でセットされた被測定モータの側面に周接する第二のコギングセンサーとになるが、該第一，第二のコギングセンサーは夫
々別々の取付けとするか、又は第一，第二のコギングセンサー双方を備える構成でもよい
。但し、この第一のコギングセンサーは大容量用コギングセンサーであり、第二のコギングセンサーは小容量用コギングセンサーである。 In this case, the cogging sensor for measuring the cogging torque is arranged in a first cogging sensor arranged at the intermediate position on the outer periphery of the lower spindle and a second cogging sensor arranged around the side of the measured motor set at the measuring position. However, the first and second cogging sensors may be separately mounted, or may be configured to include both the first and second cogging sensors. However, the first cogging sensor is a large capacity cogging sensor, and the second cogging sensor is a small capacity cogging sensor.

ここにおいて、測定位置に達し被測定モータを適宜垂下させれば、下向きモータ軸が下部スピンドルのチャック機構のチャック駒部に自動嵌入し、且つ該モータ軸受穴はロッドの下降に起因しチャック駒部が下摺動しテーパー規制を受けて閉じチャック接続になる。
一方、被測定モータの上端軸部は適宜降下する上部スピンドルで受け、縦向き姿勢の被測定モータの自動セットになる。勿論、上部スピンドルと下部スピンドルの対向間隔は、少なくとも縦向きの被測定モータのモータ軸を含む縦幅と同等又は少し大きめに設定され、該被測定モータの搬入，搬出，通過等に支障を来さない。 Here, if the measurement position is reached and the motor to be measured is appropriately suspended, the downward motor shaft is automatically fitted into the chuck piece of the chuck mechanism of the lower spindle, and the motor bearing hole is caused by the lowering of the rod, and the chuck piece Slides downward and receives a taper restriction to close the chuck.
On the other hand, the upper end shaft portion of the motor to be measured is received by an upper spindle that descends as appropriate, and the motor to be measured is automatically set in a vertical orientation. Of course, the facing distance between the upper spindle and the lower spindle is set at least equal to or slightly larger than the vertical width including the motor shaft of the motor to be measured in the vertical direction, which may hinder the loading, unloading, and passing of the motor to be measured. No.

但し、前記ロッドの昇降動は下方のシリンダーの作動子をもって行うが、該ロッドは常時（非作動時）は後退し前記チャック駒部と離反している。また、チャック駒部自体は外筒部間に介在した緩衝スプリングの収縮弾発を受け降下位置にあり、この中心のモータ軸受穴が外筒部側固定内テーパーのテーパー規制でスリットを狭める挟持状態を呈す。   However, although the rod is moved up and down by an actuator of the lower cylinder, the rod is always retracted (when not in operation) and is separated from the chuck piece. In addition, the chuck piece itself is in the lowered position due to the contraction and spring of the buffer spring interposed between the outer cylinder parts, and the center motor bearing hole is held in a state where the slit is narrowed by the taper regulation of the inner cylinder side fixed inner taper Presents.

次いで、被測定モータに対するコキングトルク測定の作動としては、前記下部スピンドルを下端に取付いた駆動用プーリを別途から適宜導くベルトの駆動をもって適宜回転（例えば１回転）させる。この下部スピンドの回転と一体的に回転するモータ軸に生ずる捩じれ度合いを電気的にコギングトルクとして捕らえる。但し、本発明にあってはコギングセンサーを大容量用コギングセンサーと小容量用コギングセンサーの２種類を備える構成を示す。   Next, as an operation for measuring the coking torque with respect to the motor under measurement, the driving pulley having the lower spindle attached to the lower end is appropriately rotated (for example, one rotation) by driving the belt as appropriate. The degree of twist generated in the motor shaft that rotates integrally with the rotation of the lower spindle is electrically captured as cogging torque. However, in the present invention, a configuration in which two types of cogging sensors, that is, a large capacity cogging sensor and a small capacity cogging sensor are shown.

即ち、被測定モータが大容量のモータでは、固定支持体より突出する下部スピンドルの中間部分に装着した環状の大容量用コギングセンサーにて測定するもので、モータ軸と一体となるチャック駒部の軸部位置にてモータ軸の捩じれを電気的に検出し、この信号を別途接続する検出機器等を経てパソコンに入力させて行なう。また、被測定モータが小容量のモータでは、前記大容量用コギングセンサーでは対処し得ず、測定位置で固定された被測定モータのモータ側面に直接周接する小容量用コギングセンサーで行なえばよい。   That is, when the motor to be measured is a large capacity motor, the measurement is performed by an annular large capacity cogging sensor attached to the middle part of the lower spindle protruding from the fixed support. This is performed by electrically detecting the twist of the motor shaft at the shaft position and inputting this signal to a personal computer through a detection device that is connected separately. Further, when the motor under measurement has a small capacity, the large capacity cogging sensor cannot cope with it, and it may be performed with a small capacity cogging sensor that directly contacts the side surface of the motor under measurement fixed at the measurement position.

なお、所定のコギングトルク測定が終わった被測定モータの搬出としては、チャック駒部をロッドの突き上げで上摺動させモータ軸受穴を広げてモータ軸の挾持を解けば、搬送路中の別途の搬出機構をもっ被測定モータを繰り出せる。   In order to carry out the motor to be measured after the predetermined cogging torque measurement is completed, if the chuck piece is lifted by sliding the rod and the motor bearing hole is widened to release the motor shaft, a separate motor in the conveyance path The measurement motor can be fed out with the carry-out mechanism.

本発明の小型モータ用コギングトルク測定支持装置は、モータ軸を下向きにした被測定モータを測定位置にあって、上，下部分を上部スピンドルと下部スピンドルで狭接セットする構成にし、且つ下部スピンドルには縦貫通の昇降自在のロッドを受けるチャック駒部を備えたチャック機構を配設し、下部スピンドル自体はコギングトルク用駆動プーリで回転し、更に下方に前記ロッドを作動するシリンダーを配するため、測定位置に臨んだ被測定モータを単に適宜落下（又は降下）させるだけでモーター軸が、ロッドの突き上げに起因しテーパー規制が解けモータ軸受穴が広がるチャック駒部に自動嵌入しセット作業の自動化がなされる。   The cogging torque measuring and supporting device for a small motor according to the present invention has a configuration in which a motor to be measured with a motor shaft facing downward is in a measuring position, and an upper spindle and a lower spindle are set tightly by an upper spindle and a lower spindle. Is equipped with a chuck mechanism with a chuck piece that receives a vertically penetrating rod, the lower spindle itself is rotated by a driving pulley for cogging torque, and a cylinder for operating the rod is disposed below. By simply dropping (or lowering) the motor to be measured at the measurement position, the motor shaft is automatically inserted into the chuck block where the taper restriction is released and the motor bearing hole expands due to the push-up of the rod. Is made.

勿論、チャック駒部のモータ軸受穴の軸部とモータ軸とは一線上になるので、偏心を招かないカップリングになりトルク測定に影響を与えない。しかも、このとき被測定モータ上端は真上位置の上部スピンドルで受ける狭接タイプを取るので該被測定モータの起立支持も確実で、単一箇所でのセット作業の簡易化に繋がる。コギングトルク検出後の被測定モータの搬出は、チャック駒部のチャック解除等の前記セット工程の逆を行えよい。   Of course, since the shaft portion of the motor bearing hole of the chuck piece and the motor shaft are on one line, the coupling does not cause eccentricity and does not affect the torque measurement. In addition, at this time, since the upper end of the motor to be measured is a narrow contact type that is received by the upper spindle at the position directly above, the motor to be measured is supported upright, leading to simplification of the setting operation at a single location. Carrying out the motor to be measured after detecting the cogging torque may be the reverse of the setting process such as releasing the chuck of the chuck piece.

しかも、本発明のコギングトルク測定支持装置は、支持装置が簡略構造となるためコギングセンサーを第一，第二のコギングセンサーとなる二種類のセンサー配置も可能になるる。即ち、下部スピンドルの上位中間部に大容量用コギングセンサー（第一のコギングセンサー）を、被測定モータのセット位置にあってモータ側面に直接周接する小容量用コギングセンサー（第二のコギングセンサー）が配設され、被測定モータ自体の容量違いに応じたコギングトルク測定ができ、より精度の高いコギングトルク検出を得る。勿論、この大容量用コギングセンサーは下部スピンドル中間部分への組み込みタイプとなる環状型コギングセンサーを用いるので、下部スピンドル自体もコンパクトになり体裁も良い。また
、小容量用コギングセンサーは小型形状で、測定時のみ横繰り出しする構成にするためセット時等に支障もなく微小のコギングトルクの検出に適する。 Moreover, since the cogging torque measuring and supporting device of the present invention has a simple structure, it is possible to arrange two types of sensors in which the cogging sensors are the first and second cogging sensors. That is, a large-capacity cogging sensor (first cogging sensor) in the upper middle part of the lower spindle, and a small-capacity cogging sensor (second cogging sensor) that is directly around the side of the motor at the set position of the motor to be measured The cogging torque can be measured according to the difference in capacity of the motor under measurement itself, and more accurate cogging torque detection can be obtained. Of course, since this large-capacity cogging sensor uses an annular cogging sensor that is incorporated into the middle part of the lower spindle, the lower spindle itself is also compact and good in appearance. In addition, the small capacity cogging sensor has a small shape and is configured to be extended laterally only at the time of measurement.

また、下部スピンドルに貫通のロッドは、真下のシリンダーで直接行う構成のためチャック駒部の昇降摺動が敏速で誤動作もない。また、モータ軸受穴の締まりはスリットに起因する部材弾発をもって行なうため、モータ軸径に多少誤差が有っても対処し得る。   In addition, the rod penetrating the lower spindle is configured to be directly performed by the cylinder directly below, so that the chuck piece is moved up and down quickly and there is no malfunction. In addition, since the motor bearing hole is tightened by the elastic member caused by the slit, even if there is some error in the motor shaft diameter, it can be dealt with.

更に、コギングトルクを与える下部スピンドル自体の回動も下端に一体の駆動プーリで直接行うため、コギングトルクの回転設定も自在になる。   Further, since the rotation of the lower spindle itself for giving the cogging torque is directly performed by the driving pulley integrated with the lower end, the rotation setting of the cogging torque can be freely set.

以下、本発明の小型モータ用コキングトルク測定支持装置を実施例の図に基づいて説明すれば、次の通りである。   Hereinafter, the coking torque measuring and supporting device for a small motor according to the present invention will be described with reference to the drawings of the embodiments.

図１乃至図４は第一，第二のコギングセンサーを備えるコギングトルク測定支持装置の実施例を示す。１は適宜のモータ把持手段（図示せず）をもつモータ搬送路２のトルク測定位置２ａにあって、その上下方向に対向配設するコギングトルク測定支持装置であり、該コギングトルク測定支持装置１の構成は、前記測定位置２ａの上方に、適宜手段（図示せず）で昇降自在となる被測定モータ３の上端３ｂを受ける昇降型上部スピンドル４を配設し、該上部スピンドル４より少なくとも被測定モータ３の縦幅ｍを隔てて同軸線上となる下方に、モータ搬送路２側の機体５に一体となる縦型固定支持体６に軸承した軸受用チャック機構７付きの下部スピンドル８を対向配設し、且つ該下部スピンドル８の下端にコギングトルク用駆動プーリ９を取付けると共に、この駆動プーリ９と下部スピンドル８の中心にはチャック解除用ロッド１０を縦貫通させ、該ロッド１０より適宜間隙を介す下方にロッド昇降用シリンダー１１を設置する。この場合、前記チャック機構７自体の構成は
、前記被測定モータ３の下向きモータ軸３ａを嵌入する適宜深さの縦切り込みスリット１２を配すモータ軸受穴１３を中心に設けた摺動型チャック駒部１４と、このチャック駒部口縁１４ａに有する外テーパー１５に接しテーパー規制をする固定内テーパー１６を設けた外筒部１７を嵌合の二重構造を取る。また、下部スピンドル８には前記固定支持体６より突出する中間部分となる頸部分８ａに嵌め込む環状型の第一のコギングセンサーである大容量用コギングセンサー１８を備る。但し、このコギングセンサー１８のセット位置はチャック駒部１４の回転軸部１４ｂに対応の外周方向に横一線上である。また、前記チャック駒部１４に二重な外筒部１７間には該チャック駒部１４を上下摺動させる緩衝スプリング１９を介在装着する。２０は外筒部１７のセット位置調整用袋ネジである。２４は前記測定位置２ａにあって縦向きにセットされた被測定モータ３の側面３ｃに、適宜横繰り出し手段（図示せず）をもって周接する第二のコギングセンサーとなる小容量用コギングセンサーである。 1 to 4 show an embodiment of a cogging torque measuring and supporting apparatus having first and second cogging sensors. Reference numeral 1 denotes a cogging torque measurement support device which is located at a torque measurement position 2a of a motor conveyance path 2 having an appropriate motor gripping means (not shown) and which is disposed so as to oppose the vertical direction thereof. In the configuration, an elevating type upper spindle 4 that receives an upper end 3b of a measured motor 3 that can be moved up and down by appropriate means (not shown) is disposed above the measurement position 2a. The lower spindle 8 with the bearing chuck mechanism 7 supported on the vertical fixed support 6 integrated with the machine body 5 on the motor conveyance path 2 side is opposed to the lower side which is on the coaxial line with the vertical width m of the measuring motor 3 therebetween. A cogging torque driving pulley 9 is attached to the lower end of the lower spindle 8 and a chuck releasing rod 10 is vertically passed through the center of the driving pulley 9 and the lower spindle 8. So, installing a rod lifting cylinder 11 downwardly via any appropriate gap from the rod 10. In this case, the structure of the chuck mechanism 7 itself is a sliding chuck piece provided around a motor bearing hole 13 in which a vertical cut slit 12 having an appropriate depth for fitting the downward motor shaft 3a of the motor 3 to be measured is provided. A double structure is adopted in which a portion 14 and an outer cylindrical portion 17 provided with a fixed inner taper 16 that is in contact with the outer taper 15 provided on the chuck piece edge 14a and regulates the taper are fitted. Further, the lower spindle 8 is provided with a large-capacity cogging sensor 18 which is an annular first cogging sensor fitted into a neck portion 8a which is an intermediate portion protruding from the fixed support 6. However, the set position of the cogging sensor 18 is on a horizontal line in the outer peripheral direction corresponding to the rotating shaft portion 14b of the chuck piece 14. In addition, a buffer spring 19 for sliding the chuck piece 14 up and down is interposed between the double outer cylinder parts 17 on the chuck piece 14. Reference numeral 20 denotes a set screw for adjusting the set position of the outer cylinder portion 17. A small-capacity cogging sensor 24 serves as a second cogging sensor that is circumferentially connected to the side surface 3c of the motor 3 to be measured, which is set in the measurement position 2a and set in the vertical direction, with appropriate lateral feeding means (not shown). .

いまこの作用を説明すると、先ずモータ搬送路２をロボット腕型把持機構等の適宜把持手段をもってモータ軸３ａを下向きにした被測定モータ３が測定位置２ａに達すると、該被測定モータ３は把持が解け自動落下又は適宜繰り込み機構をもって降下させる。この時
、測定位置２ａの上方の上部スピンドル４は被測定モータ３の上端が接しない位置まで適宜昇降手段（図示せず）にて後退する。下部スピンドル８側のチャック機構７のチャック駒部１４はロッド昇降用シリンダー１１の作動子１１の突出にてチャック解除用ロッド１０が突き上げられ、これに連動のチャック駒部１４は内装の緩衝スプリング１７の収縮弾発に抗して上摺動する。このため、チャック駒部１４のチャック駒部口縁の外テーパー１５は外筒部側固定内テーパー１６より上方にずれてテーパー規制が解けるので、モータ軸受穴１３は縦切り込みのスリット１２が部材弾発に起因し外方に広がり少し大径の穴として待機する。この場合、上部スピンドル４と下部スピンドル８の対向間隔は、被測定モータ３のモータ軸３ａを含む全幅ｍの長さを隔ててなり該被測定モータ３の搬入，通過が自在なため、この測定位置に来た被測定モータ３が落下すればモータ軸３ａは自動的にモータ軸受穴１３に嵌入される。 Now, this operation will be described. First, when the measured motor 3 with the motor shaft 3a facing downward by the appropriate gripping means such as the robot arm-type gripping mechanism reaches the measurement position 2a, the measured motor 3 is gripped. Unravel and drop with automatic drop or appropriate retraction mechanism. At this time, the upper spindle 4 above the measurement position 2a is appropriately retracted by an elevating means (not shown) to a position where the upper end of the measured motor 3 does not contact. The chuck piece 14 of the chuck mechanism 7 on the lower spindle 8 side has the chuck release rod 10 pushed up by the protrusion of the actuator 11 of the rod raising / lowering cylinder 11, and the chuck piece 14 interlocked with the chuck piece 14 has an internal buffer spring 17. It slides up against the contraction bullet. For this reason, the outer taper 15 at the edge of the chuck piece 14 of the chuck piece 14 is displaced upward from the fixed inner taper 16 on the outer cylinder side, so that the taper restriction is released. Due to the departure, it spreads outward and waits as a slightly larger hole. In this case, the distance between the upper spindle 4 and the lower spindle 8 is separated by a length of the entire width m including the motor shaft 3a of the motor 3 to be measured. If the measured motor 3 that has come to the position falls, the motor shaft 3 a is automatically fitted into the motor bearing hole 13.

ここで、前記シリンダー１１の作動で上昇したロッド１０を下降させれば、チャック駒部１４は緩衝スプリング１９の圧縮弾発に伴い降下すると共に、前記モータ軸受穴１３は該チャック駒部外テーパー１５が外筒部側固定内テーパー１６のテーパー規制を受けて径が縮まりモータ軸３ａをきつく挾持する。また、このとき上部スピンドル４も適宜降下して下端の切り欠き凹部４ａが被測定モータ３の上端に露出のモータ軸端３ｂを抑え、該被測定モータ３が測定定位置で自動的に縦向きセットとなる。   Here, if the rod 10 that has been lifted by the operation of the cylinder 11 is lowered, the chuck piece 14 descends with the compression of the buffer spring 19 and the motor bearing hole 13 has the chuck piece outer taper 15. In response to the taper restriction of the outer cylinder portion side fixed inner taper 16, the diameter is reduced and the motor shaft 3a is tightly held. At this time, the upper spindle 4 is also lowered as appropriate so that the notch recess 4a at the lower end suppresses the exposed motor shaft end 3b at the upper end of the measured motor 3, and the measured motor 3 is automatically oriented vertically at the measurement fixed position. Set.

この後、下部スピンドル８側のコギングトルク用駆動プーリ９を、該駆動プーリ９に掛けたベルト２１を介し適宜駆動手段（図示せず）に連動して回転させる。ここで駆動プーリ９が１回転すれば該駆動プーリ９に一体の下部スピンドル８も回転し被測定モータ３のモータ軸３ａが回る。   Thereafter, the driving pulley 9 for cogging torque on the lower spindle 8 side is rotated in conjunction with driving means (not shown) as appropriate via a belt 21 hung on the driving pulley 9. Here, if the drive pulley 9 rotates once, the lower spindle 8 integrated with the drive pulley 9 also rotates and the motor shaft 3a of the measured motor 3 rotates.

ここにおいて、コギングトルク検出を行う被測定モータ３が大容量である小型モータにあっては、２方式のセンサー中、下部スピンドル８の頸部分８ａに位置する第一のコギングセンーサーである大容量用コギングセンサー１８で行なう。このとき、モータ軸３ａに掛かる捩じれ度合いを電気的に検出して捕らえ、該センサー１８の検出信号を適宜接続される増幅器等を組み込むトルク制御部２２等を経てパソコン２３に入力させる。   Here, in a small motor having a large capacity to be measured motor 3 for detecting the cogging torque, the large capacity is a first cogging sensor located in the neck portion 8a of the lower spindle 8 in the two types of sensors. The cogging sensor 18 is used. At this time, the degree of twist applied to the motor shaft 3a is electrically detected and captured, and the detection signal of the sensor 18 is input to the personal computer 23 via the torque control unit 22 incorporating an amplifier or the like connected as appropriate.

また、被測定モータ３が小容量である小型モータの場合、測定位置２ａに固定セットされた被測定モータ３のモータ側面３ｃに臨む第二のコギングセンサーである小容量用コギングセンサー２４にて行なう。即ち、別途の適宜横繰り出し機構をもって小容量用コギングセンサー２４の先端をモータ側面３ｃに周接させる（図４参照）。この条件下で前記同様に下部スピンドル８を適宜回転させモータ軸３ａの捩じ度合等を直接電気信号として捕らえ、この値を同様にトルク制御部２２等を経てパソコン２３に入力する。   Further, when the motor under measurement 3 is a small motor having a small capacity, the measurement is performed by a small capacity cogging sensor 24 which is a second cogging sensor facing the motor side surface 3c of the motor under measurement 3 fixedly set at the measurement position 2a. . In other words, the tip of the small-capacity cogging sensor 24 is circumferentially contacted with the motor side surface 3c with a separate lateral feeding mechanism (see FIG. 4). Under this condition, the lower spindle 8 is appropriately rotated in the same manner as described above, and the degree of twist of the motor shaft 3a is directly captured as an electrical signal, and this value is similarly input to the personal computer 23 via the torque control unit 22 and the like.

なお、所定コギングトルクの検査が終わった被測定モータ３は、再度ロッド１０を突き上げをもってチャック駒部１４でチャッキングされたモータ軸３ａの保持を解き、上方の上部スピンドル４も後退させ適宜搬出手段（図示せず）をもって前方に搬出する。   When the test of the predetermined cogging torque has been completed, the motor under measurement 3 pushes up the rod 10 again to release the holding of the motor shaft 3a chucked by the chuck piece 14, and also retracts the upper spindle 4 at an upper position as needed. Carry it forward (not shown).

この支持装置は、被測定モータのセット機構が上下挾持形式を取り、且つコギングセンサーを下部スピンドル側に配す第一のコギングセンサー（大容量用）か、測定位置にあって被測定モータに臨む第二のコギングセンサー（小容量用）の２センサー方式を取るため
、搬入されて来る被測定モータは大容量タイプでも小容量タイプでもよく、単一の支持装置で対処し得、適宜レンジの切り替え等にコギングトルク検出がで、量産体制に適する小型モータ用コギングトルク測定支持装置になる。 This support device is a first cogging sensor (for large capacity) in which the set mechanism of the motor to be measured is vertically supported and the cogging sensor is arranged on the lower spindle side, or is at the measurement position and faces the motor to be measured. Since the second cogging sensor (for small capacity) uses a two-sensor system, the motor to be measured can be either a large capacity type or a small capacity type, and can be handled by a single support device, and the range can be switched as appropriate. Cogging torque can be detected, and it becomes a cogging torque measuring and supporting device for small motors suitable for mass production systems.
