【０００１】[0001]
本考案は、例えば、電線加工機における電線のストリップに端子等を加圧して かしめ付けする際に使用される電線やシールドワイヤー等を把持する線材把持装 置に関する。 The present invention relates to a wire rod gripping device for gripping an electric wire, a shield wire, or the like used when crimping a terminal or the like to an electric wire strip in an electric wire processing machine.
【０００２】[0002]
従来、この種の電線やシールドワイヤー等を把持する線材把持装置は、図３及 び図４に示されるように構成されている。 Conventionally, a wire rod gripping device for gripping this type of electric wire, shield wire, or the like is configured as shown in FIGS. 3 and 4.
【０００３】 即ち、図３及び図４における電線加工機において、例えば、インデックステー ブル（ターレット）のように間欠的に回転する回転円盤による搬送部材ａには、 複数（図では一個のみ示す）支持板ｂが外方へ突出して立設されており、この支 持板ｂの下部には、軸受ｃが垂直に設けられている。又、この軸受ｃには、昇降 杆ｄが上方へ突出して昇降自在に嵌装されており、この昇降杆ｄの下部には、カ ムローラｅがカム作動部材ｆで昇降するように付設されている。さらに、上記昇 降杆ｄの上部の両側面には、各ラックｇが刻設されており、この両ラックｇには 、これに噛合う各ピニオンｈが上記支持板ｂに各支軸ｉで枢着されている。さら に又、この各支軸ｉには、電線やシールドワイヤー等の線材Ｗを把持する各把持 爪部材ｊの各基部が共軸一体に軸着されており、この両把持爪部材ｊの中程には 、コイルばねｋが把持爪部材ｊを閉じる方向へ付勢して掛け渡されている。That is, in the electric wire processing machine shown in FIGS. 3 and 4, for example, a plurality of (only one is shown in the figure) support is provided on the conveying member a by a rotating disk that rotates intermittently like an index table (turret). A plate b is erected so as to project outward, and a bearing c is vertically provided below the support plate b. Further, an elevating rod d is fitted to the bearing c so as to project upward and can be moved up and down. A cam roller e is attached to the lower part of the elevating rod d so as to be elevated by a cam operating member f. There is. Further, racks g are engraved on both side surfaces of the upper part of the ascending / descending rod d, and the pinions h meshing with the racks g are attached to the support plate b by the support shafts i. It is pivotally attached. Furthermore, each base of each gripping claw member j that grips the wire W such as an electric wire or a shield wire is coaxially and integrally attached to each of the support shafts i. In the meantime, the coil spring k is urged in the closing direction of the gripping claw member j and is stretched over.
【０００４】 従って、上述した線材把持装置は、間欠的に回転する回転円盤による搬送部材 ａが線材Ｗを把持する位置に回動して停止すると、上記カム作動部材ｆが上記カ ムローラｅを下方へ降下するように引き下すので、このカムローラｅを保持する 上記昇降杆ｄが共に降下するから、この昇降杆ｄの両ラックｇがこれに噛合う各 ピニオンｈを互いに内向きに回動する。すると、この各ピニオンｈの各支軸ｉと 共軸一体の上記各把持爪部材ｊが上記コイルばねｋの弾力に幇助されながら、互 いに内向きに回動して電線等の線材Ｗを把持する。Therefore, in the wire rod gripping device described above, when the conveying member a, which is a rotating disk that rotates intermittently, rotates to a position at which it grips the wire rod W and then stops, the cam operating member f moves down the cam roller e. Since the elevating rod d holding the cam roller e descends together, both racks g of the elevating rod d rotate the pinions h meshing with the racks inward. Then, the gripping claw members j, which are coaxial with the support shafts i of the pinions h, are rotated inwardly by the elastic forces of the coil springs k, so that the wire rods W such as electric wires are wound. Hold it.
【０００５】 他方、上記搬送部材ａが線材Ｗを把持して次の加工工程へ移送され、ここで、 例えば、電線のストリップに端子等を加圧してかしめ付けし、しかる後、加工処 理された線材Ｗは、さらに、次の工程で上記各把持爪部材ｊから取外される。On the other hand, the carrying member a grips the wire W and transfers it to the next processing step, where, for example, a terminal of a wire is pressed and caulked and then processed. The broken wire W is further removed from the gripping claw members j in the next step.
【０００６】 即ち、間欠的に回転する回転円盤による搬送部材ａが線材Ｗを取外す位置に回 動して停止すると、上記カム作動部材ｆが上記カムローラｅを上方へ押し上げる ので、このカムローラｅを保持する上記昇降杆ｄが共に上昇するから、この昇降 杆ｄの両ラックｇがこれに噛合う各ピニオンｈを互いに外向きに回動する。する と、この各ピニオンｈの各支軸ｉと共軸一体の上記各把持爪部材ｊが上記コイル ばねｋの弾力に抗して互いに外向きに回動して開かれ、線材Ｗの把持を解放して この線材Ｗを上記各把持爪部材ｊから取外す。That is, when the conveying member a, which is a rotating disc that rotates intermittently, rotates to a position where the wire W is removed and then stops, the cam operating member f pushes the cam roller e upward, so that the cam roller e is held. Since the raising and lowering rods d are raised together, both racks g of the raising and lowering rods d rotate the pinions h meshing with the racks g outwardly. Then, the gripping claw members j, which are coaxially integrated with the support shafts i of the pinions h, are rotated outwardly against each other against the elastic force of the coil springs k, and the wire W is gripped. After releasing, the wire W is removed from each of the gripping claw members j.
【０００７】 又一方、図５に示される他の線材把持装置は、一対のピニオン（歯車）と思案 ばねを使用したものである。On the other hand, another wire rod gripping device shown in FIG. 5 uses a pair of pinions (gears) and a thought spring.
【０００８】 即ち、図５における電線加工機において、例えば、インデックステーブル（タ ーレット）のように間欠的に回転する回転円盤による搬送部材ａには、支持板ｂ が外方へ突出して立設されており、この支持板ｂの中程には、各ピニオンｈが互 いに噛合って各支軸ｉで枢着されている。又、この各支軸ｉには、電線等の線材 Ｗを把持する各把持爪部材ｊの各基部が共軸一体に軸着されており、この各把持 爪部材ｊの中程には、各連杆ｒの基部が各ピン軸ｍで枢着されている。さらに、 上記支持板ａの両側部には、各支承部材ｎが各ピン軸ｏで枢着されており、上記 各連杆γの各端部は上記各支承部材ｎに軸方向へ摺動自在に嵌装されており、こ の各支承部材ｎ及び上記各連杆ｒの基部との間には、各思案ばねｐが各把持爪部 材ｊを互いに閉じるように付勢して介装されている。さらに又、上記支持板ａの 両側上部には、各ストッパｑが上記各把持爪部材ｊの開いた位置を規制するよう に付設されている。That is, in the electric wire processing machine shown in FIG. 5, for example, a support plate b is erected so as to project outward on a conveying member a formed by a rotating disk that intermittently rotates like an index table (turret). In the middle of the support plate b, the pinions h are meshed with each other and are pivotally attached to the support shafts i. Also, the bases of the gripping claw members j for gripping the wire W such as an electric wire are coaxially and integrally attached to the support shafts i. The base of the connecting rod r is pivotally attached to each pin axis m. Further, each support member n is pivotally attached to each side of the support plate a by each pin shaft o, and each end of each connecting rod γ is axially slidable to each support member n. Each thought spring p is urged so as to close each gripping claw member j between each supporting member n and the base of each connecting rod r. ing. Furthermore, stoppers q are attached to upper portions of both sides of the support plate a so as to regulate the open position of the grip claw members j.
【０００９】 従って、上述した他の線材把持装置は、間欠的に回転する回転円盤による搬送 部材ａが線材Ｗを把持する位置に回動して停止すると、上記一方のピニオンｈが 図示されない歯車で回転すると、このピニオンｈに噛合う他のピニオンｈを互い に内向きに回動する。すると、この各ピニオンｈの各支軸ｉと共軸一体の上記各 把持爪部材ｊが互いに内向きに回動して線材Ｗを把持する。Therefore, in the other wire rod gripping device described above, when the conveying member a, which is a rotating disk that rotates intermittently, rotates to a position at which it grips the wire rod W and then stops, the one pinion h is operated by a gear (not shown). When rotated, the other pinions h meshing with this pinion h are rotated inwardly toward each other. Then, the gripping claw members j coaxially integrated with the support shafts i of the pinions h rotate inwardly to grip the wire rod W.
【００１０】 特に、上記各支軸ｉと各ピン軸ｏとを結ぶ仮想軸線を思案境界線Ｓとしたとき 、上記各ピン軸ｍが上記思案境界線Ｓを乗り越えて下方へ移動すると、上記思案 ばねｐの弾力で上記各把持爪部材ｊを各ストッパｑに当接するまで押し開き、し かも、上記各把持爪部材ｊを開いたままの状態に保持し、電線Ｗを授受するよう に待機する。In particular, when the virtual axis line connecting each of the support shafts i and each of the pin axes o is a thought boundary line S, when each of the pin axes m moves over the thought boundary line S and moves downward, the thought The elastic force of the spring p pushes each of the gripping claw members j open until they come into contact with each of the stoppers q. Even if each of the gripping claw members j is held in the open state, the electric wire W is put on standby. ..
【００１１】 他方、図６に示されるさらに他の線材把持装置は、一対の各把持爪部材ｊの基 部に互いに噛合う各部分歯車を形成し、この各部分歯車と思案ばねを組合わせて 使用したものである（特開昭５６−１６８３０３号）。On the other hand, still another wire rod gripping device shown in FIG. 6 forms partial gears that mesh with each other at the bases of a pair of gripping claw members j, and combines these partial gears with a speculative spring. It was used (JP-A-56-168303).
【００１２】 即ち、図６における電線加工機において、間欠的に移動するチェーンによる搬 送部材ａには、支持板ｂが外方へ突出して立設されており、この支持板ｂの中程 には、電線やシールドワイヤー等の線材Ｗを把持する各把持爪部材ｊの各基部が 各支軸ｉで枢着されている。又、この各把持爪部材ｊの各基部には、各部分歯車 ｓが互いに噛合っており、各支軸ｉの近傍の上記支持板ｂには、一対の透孔ｔが 穿設されている。さらに、この各透孔ｔの位置する上記各把持爪部材ｊの各肩部 には、各作動ピンｕが各透孔ｔの周縁へ当接するように植設されており、この各 作動ピンｕと上記支持板ｂの両側部の各ピン軸ｏとの間には、各思案ばねｐが各 把持爪部材ｊを互いに閉じるように付勢して介装されている。さらに又、上記各 透孔ｔの周縁は、上記各把持爪部材ｊの開いた位置を規制している。That is, in the electric wire processing machine shown in FIG. 6, a supporting plate b is erected on the carrying member a by a chain that moves intermittently so as to project outward, and at the middle of the supporting plate b. The bases of the gripping claw members j that grip the wire W such as an electric wire and a shield wire are pivotally attached to each support shaft i. Further, partial gears s mesh with each other at each base of each gripping claw member j, and a pair of through holes t are formed in the supporting plate b near each supporting shaft i. .. Further, each operating pin u is planted so as to abut the peripheral edge of each through hole t at each shoulder of each gripping claw member j where each through hole t is located. Each thought spring p is interposed between and each pin shaft o on both sides of the support plate b so as to bias the gripping claw members j to each other. Furthermore, the peripheral edge of each through hole t regulates the open position of each grip claw member j.
【００１３】 従って、上述した各部分歯車ｓによる線材把持装置は、間欠的に移送する搬送 部材ａが線材Ｗを把持する位置に回動して停止すると、図示されない作動杆が上 記各作動ピンｕを下方へ押下する。すると、上記各把持爪部材ｊが各支軸ｉの周 りに互いに外向きに回動して開くと共に、部分歯車ｓに噛み合う他の部分歯車ｓ を互いに外向きに回動して線材Ｗを授受して把持する態勢となる。Therefore, in the wire rod gripping device using each of the partial gears s described above, when the transport member a, which is intermittently transferred, rotates to a position at which it holds the wire rod W and stops, an operating rod (not shown) causes each of the above operating pins to operate. Press u downwards. Then, each of the gripping claw members j is rotated outwardly around each of the support shafts i to open, and at the same time, the other partial gears s 1 meshing with the partial gears s are rotated outwardly to form the wire W. It will be ready to send and receive.
【００１４】 特に、上記各支軸ｉと各ピン軸ｏとを結ぶ仮想軸線を思案境界線Ｓとしたとき 、上記各ピン軸ｍが上記思案境界線Ｓを乗り越えて下方へ移動すると、上記各思 案ばねｐの弾力で上記各把持爪部材ｊを各透孔ｔの周縁に当接するまで押し開き 、しかも、上記各把持爪部材ｊを開いたままの状態にして線材Ｗを授受して把持 する態勢にしている。In particular, when the virtual axis line connecting each of the support shafts i and each of the pin axes o is a thought boundary line S, when each of the pin axes m moves over the thought boundary line S and moves downward, The elastic force of the imaginary spring p pushes each of the gripping claw members j open until they come into contact with the peripheral edge of each of the through holes t. Further, while holding each of the gripping claw members j in the open state, the wire W is transferred to and gripped. Ready to do.
【００１５】[0015]
しかしながら、上述した各線材把持装置は、いずれも、ピニオンやラックによ る各歯車を使用している関係上、この各歯車のバックラッシュによる振動や騒音 が大きくなるばかりでなく、経時的に歯車の摩耗に伴い振動や騒音が激しくなる と共に、上記各把持爪部材ｊの線材Ｗの把持動作にも不具合を生じるおそれもあ る。 However, since each of the wire rod gripping devices described above uses gears such as pinions and racks, not only vibration and noise due to backlash of these gears increase, but also the gears change over time. Vibration and noise increase with the wear of the wire, and a problem may occur in the gripping operation of the wire W of each gripping claw member j.
【００１６】 本考案は、上述した問題を解消するために、歯車の代わりにリンク機構を使用 して経時的な使用による摩耗に伴う振動や騒音の発生を解消すると共に、長期に 亘って線材を安定して把持し、加工動作の信頼性や安全性の向上を図るようにし た線材把持装置を提供することを目的とする。In order to solve the above-mentioned problems, the present invention uses a link mechanism instead of a gear to eliminate vibration and noise due to wear due to use over time, and to prevent the wire rod from being used for a long period of time. It is an object of the present invention to provide a wire rod gripping device capable of stably gripping and improving the reliability and safety of machining operation.

In this state, the wire rod W is ready to be transferred and gripped.
【００２２】 以下、本考案の作用について説明する。The operation of the present invention will be described below.
【００２３】 従って、今、間欠的に移送する搬送部材１が電線やシールドワイヤー等の線材 Ｗを把持する位置に回動して停止すると、鎖線で示される作動部材２０が上記各 作動ローラ６、７を上方へ押動することにより、上記案内ローラ９を案内条孔８ に沿って上方へ摺動すると共に、上記各把持爪部材３、４を支軸５の周りに回動 する。すると、この各把持爪部材３、４が鎖線で示される状態に開いて線材Ｗを 授受して把持するように待機する。Therefore, when the conveying member 1 which is now intermittently transferred is rotated to a position where the wire W such as an electric wire or a shield wire is gripped and stopped, the actuating member 20 indicated by a chain line moves the actuating rollers 6, By pushing 7 upward, the guide roller 9 is slid upward along the guide slit 8 and the gripping claw members 3, 4 are rotated around the support shaft 5.
