【考案の詳細な説明】 Description of the invention]

【0001】 [0001]

【産業上の利用分野】本考案は、直立ボール盤において、主軸の工具の交換を容易になし得るように、主軸を常にそのコツタ孔が正確にクイルのコツタ孔と合致する定位置に停止させる主軸の定位置停止装置に関するものである。 INVENTION The present invention relates, in an upright drilling machine, as can no easily exchange the spindle of the tool spindle to stop the spindle at all times in a fixed position where the Kotsuta hole matches the Kotsuta hole exactly quill of the present invention relates to fixed-position stop device.

【0002】 [0002]

【従来の技術】従来のこの種の直立ボール盤(以下これを単にボール盤という。)における主軸の定位置停止装置は、見当らない。 Conventionally this type of upright drilling machine (hereinafter to simply drill press.) Fixed-position stop device of the main shaft in is not Kentora.

【0003】従来のこの種のボール盤における主軸の停止は、スイツチを切つて自然停止に任せている。 [0003] The stop of the spindle in a conventional drilling machine of this kind, are left to the switching connexion natural stop switch.

【0004】 [0004]

【考案が解決しようとする課題】上記従来のボール盤においては、スイツチを切つて主軸を停止させたときの主軸の停止位置がまちまちで、その主軸のコツタ孔の向きはその都度異なり、該主軸のコツタ孔がクイルのコツタ孔に合致することは殆んど無い。 In the above conventional drilling Disclosed invention is to provide a, with varying the main axis of the stop position when stopping the switching connexion main axis switch, the orientation of Kotsuta hole of the spindle is different each time, the main shaft it is not almost the Kotsuta hole matches the Kotsuta hole of the quill.

【0005】一方、この種のボール盤において、主軸のドリル等の工具を交換するために主軸の工具を取外すときには、コツタをクイルのコツタ孔と主軸のコツタ孔内に叩き込み、そのコツタにより工具を押出して取外す。 On the other hand, in this type of drilling machine, when removing the spindle of the tool in order to replace the tool such as a drill main axis, hammering the Kotsuta to Kotsuta the pores of Kotsuta hole and the main shaft of the quill, the tool by its Kotsuta extrusion remove Te.

【0006】従つて、従来のボール盤においては、主軸の工具を交換するために主軸の工具を取外す都度、主軸の停止後、コツタを挿入するために、作業者がクイルのコツタ孔内を覗き見ながら主軸を手で回転させてその主軸のコツタ孔をクイルのコツタ孔に合致させなければならない。 [0006] accordance go-between, in the conventional drilling machine, each time removing the main axis of the tool in order to exchange the tool of the spindle, after the stop of the main spindle, in order to insert the Kotsuta, worker peek Kotsuta within the pores of the quill while it must match the Kotsuta hole of the main spindle is rotated by hand main shaft Kotsuta hole quill.

【0007】ところで、この種のボール盤においては、 [0007] By the way, in this kind of drilling machine,
ボール盤の性格上、高速回転をするモータの回転軸から20乃至30個の歯車により歯車減速をすることで、主軸はドリル加工に適した回転になつている。 Drilling of the nature, by a gear reduction by a motor 20 to 30 of the gear from the axis of rotation of the high-speed rotation, the main shaft is decreased to the rotation suitable for drilling.

【0008】そのために、力学上、高速側、すなわちモータ側は非常に小さい力で回転させることができるけれども、逆に低速側、すなわち主軸側は大きな力でないと回転させることができない。 [0008] Therefore, dynamical, high-speed side, i.e. although the motor side can be rotated at a very small force, the low-speed side to the opposite, i.e. the spindle side can not be rotated not a large force.

【0009】従つて、1仕事に関係するドリルが、例えば3種類ある場合には、作業者は1種類のドリル加工が終る毎に、主軸のコツタ孔をクイルのコツタ孔に合致させるために、手で主軸を力一杯回転させなければならないことになり、そのドリルの交換に大きな労力が必要である上に、大変手間が掛つて作業上不便である。 [0009] accordance connexion, drill related to 1 work, for example, when three types are the operator for each type of drilling is completed, in order to match the Kotsuta hole of the spindle to Kotsuta hole quill, hand will be necessary with all one's strength rotate the main shaft, the above requires a large effort to replace the drill, very troublesome and inconvenient on hanging connexion work.

【0010】特に、大型のボール盤においては、回転減速比も大きくて主軸を手で容易に回転させることは不可能である。 [0010] Particularly, in the large drilling machine, it is not possible to easily rotated by hand rotation speed reduction ratio is large spindle. 従つて、この場合には、作業者は、主軸回転の変速レバーを中立位置に入れて主軸が軽く回転するような構成にしているけれども、この場合には、ドリルの交換のときに作業の流れが中断し、更に手間が掛つて作業上不便な点である。 Accordance connexion, in this case, the operator, although the main shaft put the shift lever of the spindle rotating in the neutral position is a configuration of rotating lightly, in this case, the flow of operations at the time of replacement of the drill There was interrupted, in that more inconvenient the troublesome multiplied connexion work.

【0011】 [0011]

【課題を解決するための手段】本考案は、ボール盤のスイツチを切つたとき、主軸は常にそのコツタ孔が正確にクイルのコツタ孔に合致して停止し、上記クイルと主軸のコツタ孔内にコツタを容易円滑に叩き込んで工具を押出し、主軸の工具の交換を迅速になし得て作業上便利な直立ボール盤における主軸の定位置停止装置を提供することを目的とする。 A solution for the present invention, when was Setsutsu the switch drilling machine, the spindle is always the Kotsuta hole stops Consistent with Kotsuta hole exactly quill, the Kotsuta bore of the quill and the spindle extrusion tool is knocked to Kotsuta easily smoothly, and to provide a fixed-position stop device of the main shaft on the work obtained without quick exchange of the spindle of the tool convenient upright drilling machine.

【考案の効果】本考案の直立ボール盤における主軸の定位置停止装置は、下記のような利点がある。 Fixed-position stop device of the main shaft of the present invention in an upright drilling machine, according to the invention], there are the following advantages.

【0028】(1) 停止スイツチを操作して主軸を停止するとき、主軸の回転数、工具の大小、長短等に関係なく、常に主軸はそのコツタ孔が正確にクイルのコツタ孔に合致して停止するから、主軸に取付けている工具を交換する場合には、主軸の停止後、直ちにコツタをクイルと主軸のコツタ孔内にわたつて叩き込み、そのコツタにより工具を主軸のテーパー挿着孔内より押出して取外すことができ、主軸の工具の交換を容易迅速になし手間と時間を節減して作業上至便である。 [0028] (1) When stopping the spindle by operating the stop switch, the rotation speed of the spindle, the size of the tool, regardless of the length or the like, always major axis thereof Kotsuta holes conform to Kotsuta hole exactly quill since stopping, when replacing a tool is attached to the spindle, after stopping of the spindle, immediately cotton the Kotsuta quill and the spindle Kotsuta bore of connexion hammering, from tapered insertion bore a tool spindle by its Kotsuta It can be removed by extrusion, working on convenient replacement of the main shaft of the tool to save easily rapidly without effort and time.

【0029】(2) 主軸を停止させるとき、インバータの変速機能によりモータの原動軸を急減速制御して一旦急減速停止させた後、低速回転させ、その低速回転の状態においてセンサからのパルス信号を入力して主軸付き受動筒を停止させる。 [0029] (2) when stopping the main shaft, after stopping once the rapid deceleration and rapid deceleration controlling driving shaft of the motor by the inverter of the transmission function, rotating at low speed, the pulse signal from the sensor in the state of the low-speed rotation enter stops the spindle with passive cylinder a. 従つて、 Follow go-between,

【0030】(イ) 主軸の原動軸を決められた所要の低速度で回転させ易い。 [0030] (it) easily rotated at a predetermined low rate determined the driving shaft of the spindle.

【0031】(ロ) 主軸付き受動筒の停止直前にはセンサからの信号パルス幅も長くて信号を確実に読み易くなつており、また、主軸付き受動筒の回転の慣性も小さいから、主軸は常にそのコツタ孔が確実にクイルのコツタ孔と合致した一定位置で停止する。 [0031] (b) immediately before the stop spindle with passive cylinder and summer easier to read reliably signal longer signal pulse width from the sensor, also, since the inertia of rotation of the main shaft with the passive cylinder is small, the main shaft always the Kotsuta holes is stopped at a certain position consistent with Kotsuta hole of reliably quill.

【0032】(3) 工具を取付けた主軸と一体で回転する受動筒にドツグを設け、そのドツグに対向して設けたセンサにより関知してインバータにより主軸の定位置停止制御を電気的に行うから、主軸の定位置停止を正確になし得る。 [0032] (3) provided Dotsugu passive cylinder rotates spindle integrally attached to the tool, since electrically performing fixed-position stop control of the spindle by the inverter concerned by a sensor provided so as to oppose the Dotsugu It may form a fixed-position stop of the spindle accurately.

【0033】(4) 主軸部にセンサを設けるのみで、 [0033] (4) only providing a sensor on the main shaft portion,
主軸の定位置停止を電気的に行うから、機械的の主軸定位置停止機構が不要となり、構造が簡単で容易安価に製作できる。 Since electrically performing fixed-position stop of the spindle, the mechanical main shaft fixed-position stop mechanism is not required, the structure can be simple and easily manufactured at low cost.

【0034】(5) 主軸に連結したモータを制御するから、歯車の変速に関係なく、また、主軸を高速回転からでも直接急停止することができ、停止時間を短縮して作業性が良い。 [0034] (5) from controlling a motor coupled to the main shaft, regardless of the speed change gear, also the main shaft and can be suddenly stopped directly from any high speed, good workability and reduce downtime.

【0035】(6) 主軸の定位置停止を行うだけであるから、簡易形定位置制御回路でよく、電気回路が簡単で、低価格で作製できる。 [0035] (6) since only the constant position stop of the spindle may be a simple type position control circuit, the electric circuit is simple, can be manufactured at low cost.

【0036】(7) 電気式制御であるから、外部からの衝撃に対しても破損することなく、耐久性は大である。 [0036] (7) because it is electrical control without also broken against impact from the outside, durability is large.
