Description

本考案は一種の工具用ハンドルに係り、特に金属及び非金属材に対して孔開けするための工具を簡単に着脱できる工具用ハンドルに関する。   The present invention relates to a kind of tool handle, and more particularly to a tool handle in which a tool for punching a metal and a non-metal material can be easily attached and detached.

孔開け技術領域においては、通常、下端にドリルを設けたさん孔体を回転させて、一定速度下で孔開け作業を行い、孔の直径に合わせてさん孔体を交換する。ゆえに続々と各種の円孔切削に必要な工具を挟持し、簡単且つ確実に工具の交換作業が行なえるハンドルが開発されている。   In the drilling technology area, a punched body provided with a drill at the lower end is usually rotated to perform a drilling operation at a constant speed, and the punched body is exchanged according to the diameter of the hole. Therefore, a handle has been developed which can easily and surely perform tool replacement work by holding various tools necessary for cutting various circular holes one after another.

図1は周知のハンドル(1)を示し、その一端は駆動部(11)とされ、別端は筒状嵌合部(12)とされ、工具(13)の頭部(14)はこの嵌合部(12)に挿入される。工具(13)の頭部(14)と異なる一端は筒形刃部(15)とされ、中心ドリル(16)が挿入端(17)を以て工具(13)の中央の孔(18)を通りハンドル(1)に挿入され、このハンドル(1)にネジ部品(19)によりそれぞれ工具(13)と中心ドリル(16)が緊迫固定される。   FIG. 1 shows a known handle (1), one end of which is a drive part (11), the other end is a cylindrical fitting part (12), and the head (14) of a tool (13) is fitted with this fitting. It is inserted into the joint (12). One end different from the head (14) of the tool (13) is a cylindrical blade (15), and the center drill (16) passes through the center hole (18) of the tool (13) with the insertion end (17) and is handled. The tool (13) and the center drill (16) are pressed and fixed to the handle (1) by screw parts (19), respectively.

一般に工作物に孔開けを行なう時に発生する反作用力は、直接工具(13)と中心ドリル(16)に伝わり、このためネジ部品(19)が緩んで、工具(13)或いは中心ドリル(16)がハンドル(1)の制御より離脱して脱落しやすい。このほか緊迫固定される工具(13)の頭部(14)、さらには中心ドリル(16)の挿入端(17)はいずれもハンドル(1)内部と許容されるギャップを有し、このギャップは加工時に形成される誤差でもあり、このギャップはネジ部品(19)によっては解消されず、操作時に工具(13)或いは中心ドリル(16)がハンドル(1)内に縮入する可能性があり、円孔の切削品質と制度に影響が生じる。   In general, the reaction force generated when drilling a workpiece is directly transmitted to the tool (13) and the center drill (16), so that the screw part (19) is loosened, and the tool (13) or the center drill (16). However, it is easy to come off and fall off from the control of the handle (1). In addition, the head (14) of the tool (13) to be tightened and the insertion end (17) of the center drill (16) all have an allowable gap with the inside of the handle (1). It is also an error formed during processing, and this gap is not eliminated by the screw component (19), and the tool (13) or the center drill (16) may be retracted into the handle (1) during operation. The cutting quality and system of the hole will be affected.

図2、3は別の快速着脱式の孔開け工具の構造であり、ハンドル(2)に環状の工具(21)が嵌合され、この工具(21)の中央に中心ピン(22)が連結され、ビーズ(23)がスリーブ(24)の異なる内径部分を転がる機構を利用し、簡単に工具(21)をハンドル(2)に対して装着或いは分離させられる。凹部(25)の深さが不一致であるため、ビーズ(23)が凹部(25)に嵌入した後に、スリーブ(24)の内周と僅かなギャップが発生し得て、これにより工具(21)がハンドル(2)においてぐらつき、間接的に中心ピン(22)の正確性に影響が生じる。   2 and 3 show another rapid detachable drilling tool structure in which an annular tool (21) is fitted to the handle (2), and a center pin (22) is connected to the center of the tool (21). Then, the tool (21) can be easily attached to or detached from the handle (2) using a mechanism in which the beads (23) roll on different inner diameter portions of the sleeve (24). Since the depths of the recesses (25) are inconsistent, a slight gap may occur with the inner periphery of the sleeve (24) after the beads (23) are fitted into the recesses (25), thereby causing the tool (21). Will wobble in the handle (2), indirectly affecting the accuracy of the center pin (22).

本考案の目的の一つは、一種の工具用ハンドルを提供することにあり、それは工具の着脱を速やかに行なえ、工具を圧迫してハンドルに緊接させられるものとする。   One of the objects of the present invention is to provide a kind of tool handle, which can quickly attach and detach the tool and press the tool to be brought into close contact with the handle.

As is apparent when referring to FIG. 6, a vertical wall surface (421) is formed between two inner diameters of the movable ring (42), and the wall surface (421) is formed from an opening at one end of the maximum inner diameter. However, an annular storage space (422) is formed on the outer periphery of the fitting portion (33). A plurality of equally detachable grooves (423) are recessed in a relatively large inner diameter portion of the wall surface (421) from an opening at one end of the smallest inner diameter, and a radius is provided between two adjacent detachable grooves (423). A pressing portion (424) is formed which is equal to the wall surface.

該押さえ部(424)の嵌合部(33)の接続孔(34)に対応する一端において、開口の部分に軌道(425)が凹設され、別端に該壁面(421)より内向きに傾斜するテーパ面(426)が設けられ、該テーパ面(426)が受け孔(55)を押圧して工具(5)のハンドル(3)からの離脱を防止する。   At one end corresponding to the connection hole (34) of the fitting portion (33) of the pressing portion (424), a track (425) is recessed in the opening, and the other end is inward from the wall surface (421). An inclined tapered surface (426) is provided, and the tapered surface (426) presses the receiving hole (55) to prevent the tool (5) from being detached from the handle (3).

前述のスナップリング(43)はワッシャ(44)と合わせて該ハンドル(3)の嵌合部(33)外周に嵌合され、該可動リング(42)を制限して嵌合部(33)の両端からの脱出を防止する。そのうち、一つのワッシャ(44)が該可動リング(42)の収容空間(422)に挿入され、該ワッシャ(44)と壁面(421)の間に弾性部品(45)が設置され、弾力を利用して該可動リング(42)が押動されて連接部(32)に近いワッシャ(44)が押圧される。   The snap ring (43) is fitted to the outer periphery of the fitting portion (33) of the handle (3) together with the washer (44), and the movable ring (42) is limited to the fitting portion (33). Prevent escape from both ends. Among them, one washer (44) is inserted into the accommodating space (422) of the movable ring (42), and an elastic part (45) is installed between the washer (44) and the wall surface (421) to use elasticity. Then, the movable ring (42) is pushed and the washer (44) close to the connecting portion (32) is pressed.

前述の中心ドリル(57)は該工具(5)中に挿入され、図6に示されるように、該中心ドリル(57)の刃のない一端は該工具(5)の頭部(53)を通過して該ハンドル(3)の連接部(32)内に挿入され、ネジ部品(19)により該ハンドル(3)に緊迫固定される。   The aforementioned center drill (57) is inserted into the tool (5), and as shown in FIG. 6, one end of the center drill (57) without a blade pushes the head (53) of the tool (5). It passes through and is inserted into the connecting part (32) of the handle (3), and is fastened to the handle (3) by a screw part (19).

該ハンドル(3)は駆動部(31)により続けて動力を受けて回転する。該中心ドリル(57)は直接ハンドル(3)に連帯回転して工作物に孔開けし、また該固定部品(56)はU形溝(54)の壁面を押動し、該工具(5)を駆動し間接的にハンドル(3)に伴い回転させて研削を行ないうる。   The handle (3) is continuously rotated by receiving power from the drive unit (31). The central drill (57) rotates in unison with the handle (3) directly to pierce the workpiece, and the fixed part (56) pushes the wall surface of the U-shaped groove (54), and the tool (5) Can be driven and rotated indirectly with the handle (3) for grinding.

図8、9に示されるように、該可動リング(42)はハンドル(3)が回転動作し、該嵌合部(33)の突出するピン(36)がその軌道(425)上に抵触し、該軌道(425)の勾配に沿って高低落差を形成し、該可動リング(42)を案内して弾性部品(45)に向けてある角度回転移動させる。こうして、該可動リング(42)の壁面(421)が弾性部品(45)を押圧し、同時に該ビーズ(41)のテーパ面(426)を制圧し、該可動リング(42)が回転して近隣の着脱溝(423)に変換され、該着脱溝(423)の半径はテーパ面(426)より大きく、ゆえに該受け孔(55)はそれ以上ビーズ(41)の制圧を受けず、工具(5)の取り外しが簡単に達成される。   As shown in FIGS. 8 and 9, the movable ring (42) has the handle (3) rotated, and the protruding pin (36) of the fitting portion (33) collides with the track (425). A height difference is formed along the gradient of the track (425), and the movable ring (42) is guided and rotated by an angle toward the elastic part (45). In this way, the wall surface (421) of the movable ring (42) presses the elastic part (45), and at the same time controls the tapered surface (426) of the bead (41), and the movable ring (42) rotates to the vicinity. , And the radius of the detachable groove (423) is larger than the tapered surface (426), so that the receiving hole (55) is not subjected to further pressure suppression of the beads (41), and the tool (5 ) Removal is easily achieved.

同様に該可動リング(42)を回転させて、必要なさん孔体(51)の工具(5)を取り付けることができ、該固定部品(56)を対応するU形溝(54)中に挿入できる。反対方向に可動リング(42)を回転させると、該テーパ面(426)は再度ビーズ(41)を制圧し、該受け孔(55)がビーズ(41)の制圧を受け、弾力で該テーパ面(426)の押圧作用を補助する作用下で、該工具(5)の頭部(53)の端面(531)が嵌合部(33)の内端面(331)に緊密に当接するか、或いは該頭部(53)とさん孔体(51)の間の垂直壁面(511)が、該嵌合部(33)の開口端の環形壁面(332)に当接し、工具(5)がしっかりとハンドル(3)に接合され、安定した孔開け加工が行なえる。端面(531)、内端面(331)、垂直壁面(511)及び環形壁面(332)の対応位置については図5を参照されたい。   Similarly, the movable ring (42) can be rotated to attach the necessary punch (51) tool (5) and the fixed part (56) inserted into the corresponding U-shaped groove (54). it can. When the movable ring (42) is rotated in the opposite direction, the tapered surface (426) again controls the bead (41), and the receiving hole (55) receives the pressure of the bead (41), and the tapered surface is elastically elastic. Under the action of assisting the pressing action of (426), the end face (531) of the head part (53) of the tool (5) closely contacts the inner end face (331) of the fitting part (33), or The vertical wall surface (511) between the head (53) and the punched body (51) abuts on the annular wall surface (332) at the open end of the fitting portion (33), and the tool (5) is firmly attached. Bonded to the handle (3), stable drilling can be performed. Refer to FIG. 5 for the corresponding positions of the end surface (531), the inner end surface (331), the vertical wall surface (511), and the annular wall surface (332).
