Description

本発明は、トルク工具の調整に関し、特に、工具のトルク値を調整する装置に関する。   The present invention relates to adjustment of a torque tool, and more particularly to an apparatus for adjusting a torque value of a tool.

一般のトルク工具のほとんどはトルクレンチ及びトルクドライバーである。トルクレンチ又はトルクドライバーであっても、工具のトルク値を調整するトルク調整装置を備えていることが一般的である。   Most common torque tools are torque wrenches and torque drivers. Even a torque wrench or torque driver is generally provided with a torque adjusting device for adjusting the torque value of the tool.

従来のトルク調整装置は種類が多く、そのうちトルク調整装置の一種は、つまみと制御リングとにより構成され、つまみの外壁にはギザギザが周設され、制御リングの内壁にもギザギザが周設されている。これらギザギザの長手方向は、制御リングの軸心と略平行であり、互いに噛み合わされてつまみが旋回することを制限する。   There are many types of conventional torque adjustment devices. Among them, one type of torque adjustment device is composed of a knob and a control ring, and the outer wall of the knob has a jagged circumference, and the control wall has a jagged circumference. Yes. These jagged longitudinal directions are substantially parallel to the axis of the control ring and are engaged with each other to limit the turning of the knob.

つまみから力を受けて外側へ引っ張られてギザギザの噛合範囲から離脱されると、つまみを旋回させて工具のトルク値を調整することができ、つまみが再び制御リングに圧入されると、トルク値は不用意に変更されなくなる。   When the force is applied to the knob and pulled outwards to leave the jagged engagement range, the torque value of the tool can be adjusted by turning the knob, and when the knob is press-fitted into the control ring again, the torque value Will not be changed inadvertently.

つまみに球体を取付け、その球体は弾性部材によりつまみの外側へ押動される。つまみが圧入されている期間は、制御リングが球体を押圧し続け、つまみに抵抗力が生じる。つまみが外側へ引っ張られている間、球体は制御リングの制限を受けずに跳ね出やすいため、最悪の場合紛失してしまい、トルクの調整に大きな影響を与えることがあった。   A sphere is attached to the knob, and the sphere is pushed to the outside of the knob by the elastic member. During the time when the knob is press-fitted, the control ring continues to press the sphere, and a resistance force is generated on the knob. While the knob is pulled outward, the sphere easily jumps out without being restricted by the control ring, and in the worst case, it is lost, which may greatly affect the torque adjustment.

本案には、トルク工具の調整装置を改善するために本発明者が取得した台湾実用新案登録第M371616号及び台湾特許第I541108号を参考にすることができる。   Reference can be made to Taiwan Utility Model Registration No. M371616 and Taiwan Patent No. I541108 acquired by the present inventor in order to improve the torque tool adjusting device.

本発明の目的は、直線運動の係合構造を利用して少なめの部品で同様の離合効果を得て、製作コストを減らし、市場競争力を高めるトルク調整装置を提供することにある。   An object of the present invention is to provide a torque adjusting device that obtains the same separation effect with a small number of parts by using a linear motion engagement structure, reduces manufacturing costs, and increases market competitiveness.

図1、図4及び図5を参照する。図1、図4及び図5に示すように、本発明の一実施形態に係るトルク調整装置は、ねじ、ナットなどの締付け具に一定のトルク値を伝える工具の一部の構造が示されている。上述した工具とは、本実施形態ではトルクレンチ60を指すが、他の実施形態ではトルクドライバー(図示せず)を指してもよい。   Please refer to FIG. 1, FIG. 4 and FIG. As shown in FIGS. 1, 4 and 5, the torque adjusting device according to one embodiment of the present invention shows a partial structure of a tool that transmits a constant torque value to a fastening tool such as a screw or a nut. Yes. The tool described above refers to the torque wrench 60 in this embodiment, but may refer to a torque driver (not shown) in other embodiments.

さらに詳細には、トルクレンチ60は、中空状のハンドル61を有する。ハンドル61の内部には、伝動杆62、ソケット63及び目盛リング65が配設される。伝動杆62は、ハンドル61中に取り付けられた軸受71により阻まれているため、ハンドル61が離脱し難くなり、ハンドル61内部で自転する。ソケット63は、連続した複数の内歯64を有し、ソケット63がハンドル61内に配置されて固定され、これら内歯64は、ソケット63により支えられて伝動杆62の外周に設けられる。上述したソケット63は、目盛リング65に挿設され、ハンドル61に形成されたウィンドウ68に対して目盛リング65が旋回することを支える。また、ハンドル61のウィンドウ68中にレンズ69を組み込み、目盛リング65を拡大する機能を得てもよい。上述した目盛リング65は、外歯66及び複数の識別部67を有する。外歯66は、円周方向に沿って目盛リング65の外表で***し、互いに連続するように配列される。識別部67は、目盛リング65の外周面に形成され、各識別部67はアラビア数字であり、レンズ69の下方まで目盛リング65が旋回し、トルクレンチ60のトルク値を判読する助けとなる。   More specifically, the torque wrench 60 has a hollow handle 61. Inside the handle 61, a transmission rod 62, a socket 63, and a scale ring 65 are disposed. Since the transmission rod 62 is blocked by a bearing 71 attached in the handle 61, the handle 61 is difficult to be detached and rotates inside the handle 61. The socket 63 has a plurality of continuous internal teeth 64, and the socket 63 is disposed and fixed in the handle 61. The internal teeth 64 are supported by the socket 63 and provided on the outer periphery of the transmission rod 62. The socket 63 described above is inserted into the scale ring 65 and supports the turning of the scale ring 65 with respect to the window 68 formed in the handle 61. Further, a lens 69 may be incorporated in the window 68 of the handle 61 to obtain a function for enlarging the scale ring 65. The scale ring 65 described above has external teeth 66 and a plurality of identification portions 67. The external teeth 66 bulge on the outer surface of the scale ring 65 along the circumferential direction and are arranged so as to be continuous with each other. The identification part 67 is formed on the outer peripheral surface of the scale ring 65, and each identification part 67 is an Arabic numeral, and the scale ring 65 turns to the lower side of the lens 69, and helps to read the torque value of the torque wrench 60.

トルクレンチ60の構造は、前述した台湾特許第I541108号と略同じであり、当該案の明細書を参照すれば分かるため、ここでは詳しく述べない。   The structure of the torque wrench 60 is substantially the same as the aforementioned Taiwan Patent No. I541108, and will not be described in detail here since it can be understood by referring to the specification of the proposal.

図1〜図5から分かるように、トルクレンチ60は、トルク調整装置と結合し、トルク調整装置によりトルク値を調整する。本発明の一実施形態に係るトルク調整装置は、本体10、係合部材20、操作杆30、球体40、弾性部材42、つまみ50及び押ボタン56から構成されてなる。   As can be seen from FIG. 1 to FIG. 5, the torque wrench 60 is coupled to the torque adjustment device and adjusts the torque value by the torque adjustment device. The torque adjustment device according to an embodiment of the present invention includes a main body 10, an engagement member 20, an operating rod 30, a sphere 40, an elastic member 42, a knob 50, and a push button 56.

本体10は、両端を有し、それら両端はトンネル11に挿通される。本体10は、中空状である。穿孔12は、本体10に垂直に穿設されてトンネル11と連通する。要するに、トンネル11が本体10の軸心方向で延び、本体10の径方向で延びた穿孔12と交差する。そのため、トンネル11と穿孔12とが連通する。   The main body 10 has both ends, and both the ends are inserted into the tunnel 11. The main body 10 is hollow. The perforation 12 is drilled perpendicularly to the main body 10 and communicates with the tunnel 11. In short, the tunnel 11 extends in the axial direction of the main body 10 and intersects with the perforations 12 extending in the radial direction of the main body 10. Therefore, the tunnel 11 and the perforation 12 communicate with each other.

外部の輪郭から見ると、本体10の両端間は凸部13、筒部14、皿体部15及び扁平部16に分けられる。凸部13及び筒部14は、本体10の両端にそれぞれ設けられ、両者は皿体部15を介して扁平部16と接続される。上述した扁平部16は、筒部14と皿体部15との間に位置し、扁平部16及び凸部13は、皿体部15の両側に位置する。扁平部16の厚さは、凸部13又は筒部14の最大直径より小さく、穿孔12が扁平部16の中間部に挿通される。2つの取付余裕孔121は、扁平部16に周設された穿孔12の壁に挿通され、各取付余裕孔121は、穿孔12と接続される。   When viewed from the outer contour, the two ends of the main body 10 are divided into a convex portion 13, a cylindrical portion 14, a dish body portion 15 and a flat portion 16. The convex portion 13 and the cylindrical portion 14 are provided at both ends of the main body 10, respectively, and both are connected to the flat portion 16 via the dish body portion 15. The flat part 16 mentioned above is located between the cylinder part 14 and the dish part 15, and the flat part 16 and the convex part 13 are located in the both sides of the dish part 15. FIG. The thickness of the flat part 16 is smaller than the maximum diameter of the convex part 13 or the cylindrical part 14, and the perforation 12 is inserted through the intermediate part of the flat part 16. The two attachment allowance holes 121 are inserted through the wall of the perforation 12 provided around the flat portion 16, and each attachment allowance hole 121 is connected to the perforation 12.

上述した係合部材20は、複数の歯21及び可動孔22を有する。これら複数の歯21は、係合部材20の外表に連続的に形成され、通常、係合部材20の頂面を指す。可動孔22が係合部材20の中間部に挿通され、係合部材20が穿孔12に配設されている期間、可動孔22は、本体10のトンネル11の真正面に対向する。このとき係合部材20が扁平部16に周設された穿孔12の壁により制限されるため、本体10の直径方向で退縮位置と延伸位置との間で往復運動する。言い換えれば、係合部材20は、本体10に対して直線状の往復運動をする。   The engaging member 20 described above has a plurality of teeth 21 and a movable hole 22. The plurality of teeth 21 are continuously formed on the outer surface of the engagement member 20, and generally indicate the top surface of the engagement member 20. During the period in which the movable hole 22 is inserted into the intermediate portion of the engagement member 20 and the engagement member 20 is disposed in the perforation 12, the movable hole 22 faces the front surface of the tunnel 11 of the main body 10. At this time, since the engaging member 20 is limited by the wall of the perforation 12 provided around the flat portion 16, the engaging member 20 reciprocates between the retracted position and the extended position in the diameter direction of the main body 10. In other words, the engagement member 20 reciprocates linearly with respect to the main body 10.

上述した操作杆30は、深入端31及び露出端32を有する。凸曲面33は、深入端31の端面に設けられる。操作杆30は、本体10のトンネル11に設置され、深入端31がトンネル11を介して穿孔12内に達し、係合部材20の可動孔22中に進入する。   The operation rod 30 described above has a deep insertion end 31 and an exposed end 32. The convex curved surface 33 is provided on the end surface of the deep insertion end 31. The operating rod 30 is installed in the tunnel 11 of the main body 10, and the deep insertion end 31 reaches the inside of the hole 12 through the tunnel 11 and enters the movable hole 22 of the engagement member 20.

このとき枢軸17は、凸部13と操作杆30との間に挿通され、凸部13から突出した露出端32を支える。操作杆30及び本体10は、枢軸17により接続され、操作杆30が鐘のように本体10内で行ったり来たり揺動する。また、係合部材20と、操作杆30の深入端31とが支杆18により旋回可能な連結関係になるまで、支杆18は扁平部16の取付余裕孔121を通過する。   At this time, the pivot 17 is inserted between the convex portion 13 and the operating rod 30 and supports the exposed end 32 protruding from the convex portion 13. The operating rod 30 and the main body 10 are connected by the pivot 17, and the operating rod 30 moves back and forth within the main body 10 like a bell. Further, the support rod 18 passes through the mounting allowance hole 121 of the flat portion 16 until the engagement member 20 and the deep insertion end 31 of the operation rod 30 are connected to each other so as to be pivotable by the support rod 18.

支杆18の長さ(図7を参照する)は、穿孔12の2つの短辺壁面の離間距離より小さいため、操作杆30の深入端31は、円周方向で枢軸17の周りで往復運動し、本体10又は扁平部16の影響又は干渉を受けることはない。   Since the length of the support rod 18 (see FIG. 7) is smaller than the distance between the two short side walls of the perforation 12, the deep insertion end 31 of the operation rod 30 reciprocates around the pivot 17 in the circumferential direction. However, there is no influence or interference from the main body 10 or the flat portion 16.

つまみ50の外表には凹凸があるため、接触面積が拡大し、強く握ったりねじったりする操作がし易い。つまみ50の内部は中空であり、リング部53により画成され、つまみ50の内部空間は外槽51と空洞52とに分けられる。外槽51は、中空のリング部53を介して空洞52と連通する。つまみ50は、第1の噛合部54及び複数の貫通孔55を有する。上述した第1の噛合部54は、連続した複数の歯であり、これら複数の歯は、つまみ50に周設された空洞52の壁の内周面に突設されている。これら複数の貫通孔55は、リング部53に形成され、少なくとも1つのねじ44が対応した貫通孔55に挿通され、皿体部15に螺着すると、つまみ50と本体10とが結合される。   Since the outer surface of the knob 50 has irregularities, the contact area is enlarged, and it is easy to perform an operation of grasping and twisting strongly. The inside of the knob 50 is hollow and is defined by a ring portion 53, and the internal space of the knob 50 is divided into an outer tank 51 and a cavity 52. The outer tub 51 communicates with the cavity 52 through a hollow ring portion 53. The knob 50 has a first meshing portion 54 and a plurality of through holes 55. The first meshing portion 54 described above is a plurality of continuous teeth, and the plurality of teeth protrude from the inner peripheral surface of the wall of the cavity 52 provided around the knob 50. The plurality of through holes 55 are formed in the ring portion 53, and when the at least one screw 44 is inserted into the corresponding through hole 55 and screwed into the plate body portion 15, the knob 50 and the main body 10 are coupled.

上述した押ボタン56は、結合孔57を有する。押ボタン56をつまみ50の外槽51に挿入し、ボルト46が結合孔57を介して操作杆30の露出端32に螺着されると、押ボタン56と操作杆30とが接続され、押ボタン56は、つまみ50に対して切換えすることができる。   The push button 56 described above has a coupling hole 57. When the push button 56 is inserted into the outer tub 51 of the knob 50 and the bolt 46 is screwed to the exposed end 32 of the operation rod 30 through the coupling hole 57, the push button 56 and the operation rod 30 are connected to each other. The button 56 can be switched with respect to the knob 50.

図5〜図7を参照する。以下、図5〜図7に基づき、トルク調整装置をトルクレンチ60に結合する具体的な構造について詳細に説明する。   Please refer to FIG. Hereinafter, a specific structure for coupling the torque adjusting device to the torque wrench 60 will be described in detail with reference to FIGS.

皿体部15がソケット63で止められるまで、本体10をハンドル61に挿入し、筒部14が伝動杆62の一部に嵌合されるようにする。押付け部材70は、筒部14に形成された押付け孔19を介して伝動杆62中に挿入され、本体10を伝動杆62に接続して離脱し難くし、両者が同じ方向で旋回可能となる。   The main body 10 is inserted into the handle 61 until the dish body portion 15 is stopped by the socket 63 so that the cylindrical portion 14 is fitted to a part of the transmission rod 62. The pressing member 70 is inserted into the transmission rod 62 through the pressing hole 19 formed in the cylindrical portion 14, and the main body 10 is connected to the transmission rod 62 to be difficult to be separated, and both can turn in the same direction. .

続いて、球体40が弾性部材42を圧迫し、伝動杆62の端部に共に深く入れられる。本実施形態において、弾性部材42は、圧縮バネであり、一端が伝動杆62に当接され、他端が球体40を押動して操作杆30の深入端31に接触され、球体40は操作杆30を位置決めする。凸曲面33の中央部は両端より高いため、球体40が凸曲面33の何れか1つの低端に接触されると、一般に操作杆30の揺動に耐衝撃性の作用が発生し、ボルト46の位置が不用意に変化することを防ぐ。   Subsequently, the sphere 40 presses the elastic member 42 and is inserted deeply into the end of the transmission rod 62. In this embodiment, the elastic member 42 is a compression spring, one end abuts on the transmission rod 62, the other end pushes the sphere 40 and contacts the deep insertion end 31 of the operation rod 30, and the sphere 40 is operated. Position the heel 30. Since the central portion of the convex curved surface 33 is higher than both ends, generally, when the sphere 40 is brought into contact with any one of the low ends of the convex curved surface 33, an impact resistance action is generated in the swinging of the operating rod 30, and the bolt 46 To prevent inadvertent changes in position.

図示するように、係合部材20は延伸位置にある。操作杆30の深入端31が円周運動に沿って高めに位置し、押ボタン56が図面の下方へ移動する以外に、同時に制限して(又は押動と称する)係合部材20が本体10に沿って穿孔12から径方向で延び、各歯21が本体10での高さが増大し、歯21が噛着されるかソケット63に対応した内歯64と噛合する。   As illustrated, the engagement member 20 is in the extended position. In addition to the deep insertion end 31 of the operating rod 30 being positioned higher along the circumferential motion and the push button 56 moving downward in the drawing, the engaging member 20 is restricted (or referred to as “pushing”) at the same time. And the teeth 21 are increased in height in the main body 10, and the teeth 21 are engaged or engaged with the internal teeth 64 corresponding to the socket 63.

このときソケット63が固定され、本体10とつまみ50とは旋回しない。そのためトルクレンチ60を操作して締付け具を締め付けたり緩めたりし、つまみ50に誤って接触し、トルク値が不用意に大きくなったり小さくなったりすることを防ぐことができる。   At this time, the socket 63 is fixed, and the main body 10 and the knob 50 do not pivot. Therefore, it is possible to prevent the torque value from being accidentally increased or decreased by operating the torque wrench 60 to tighten or loosen the fastener and accidentally touching the knob 50.

図8及び図9を参照する。図8及び図9に示すように、係合部材20は、退縮位置にある。押ボタン56は、図面の上方へ移動し、操作杆30の深入端31が円周運動に沿って低めの位置へ移動し、係合部材20が本体10に沿って径方向で穿孔12へ引き込まれる(又は引っ張りと称する)ことを制限し(図3を参照する)、各歯21が本体10での高さが下がると、歯21と内歯64との噛着又は噛合関係が解除される。   Please refer to FIG. 8 and FIG. As shown in FIGS. 8 and 9, the engagement member 20 is in the retracted position. The push button 56 moves upward in the drawing, the deep insertion end 31 of the operating rod 30 moves to a lower position along the circumferential movement, and the engaging member 20 is drawn into the perforation 12 in the radial direction along the main body 10. (Referring to FIG. 3), and when the teeth 21 are lowered in height in the main body 10, the engagement or engagement relationship between the teeth 21 and the internal teeth 64 is released. .

このように、つまみ50は自由であり、力を受けてハンドル61により旋回することが可能であり、皿体部15により筒部14が伝動杆62で同じ方向で旋回され、トルクレンチ60のトルク値を調整することができる。   In this manner, the knob 50 is free and can be swung by the handle 61 under force, and the cylinder portion 14 is swung in the same direction by the transmission rod 62 by the dish body portion 15, and the torque of the torque wrench 60 is increased. The value can be adjusted.

また、目盛リング65の一部がつまみ50の空洞52に配置され、外歯66が第1の噛合部54に噛合し、目盛リング65がつまみ50に伴って同期で作動する。またレンズ69により目盛リング65の識別部67を観察し(図4を参照する)、トルクレンチ60の現在のトルク値を速やかに判読することができるため、非常に簡便である。   Further, a part of the scale ring 65 is disposed in the cavity 52 of the knob 50, the external teeth 66 are engaged with the first engagement portion 54, and the scale ring 65 is operated in synchronization with the knob 50. Further, the identification part 67 of the scale ring 65 is observed with the lens 69 (see FIG. 4), and the current torque value of the torque wrench 60 can be quickly read, which is very simple.

また押ボタン56を図面の下方へ移動させると、係合部材20が退縮位置から延伸位置へ切換えられ、トルクレンチ60のトルク値を維持することができる。   When the push button 56 is moved downward in the drawing, the engagement member 20 is switched from the retracted position to the extended position, and the torque value of the torque wrench 60 can be maintained.
