Description
本発明は、トルク値設定システム、トルク値設定装置、及び、トルク値設定方法に関する。
The present invention relates to a torque value setting system, a torque value setting device, and a torque value setting method.
従来から、ボルトやナットなどの締付部材を締付箇所に締め付けるときの締付トルクを測定することにより、締付トルクを管理することができる締付工具として、トルクレンチが知られている。一般に、トルクレンチには、測定する締付トルクの数値の変更ができない単能型トルクレンチと、作業者の操作により測定できる締付トルクの値の変更ができるプレセット型トルクレンチとがある。
Conventionally, a torque wrench is known as a tightening tool capable of managing the tightening torque by measuring the tightening torque when a tightening member such as a bolt or a nut is tightened at a tightening location. In general, there are two types of torque wrench: a single-function type torque wrench that cannot change the numerical value of the tightening torque to be measured, and a preset type torque wrench that can change the value of the tightening torque that can be measured by an operator's operation.
機械式のプレセット型トルクレンチでは、締付部材を締め付ける際に、締付トルクが設定された設定値に達すると、スプリングからの圧縮力が接続部を中心にトグルが回動する方向に働く。トグルが接続部を中心に回動することにより、トグルは、ヘッド部に対して摺動する。トルクレンチでは、トグルがヘッド部に対して摺動してケースなど他の箇所に接触すると、トルクレンチから音と振動が発生する。作業者は、トルクレンチから発生する音や振動により、締付部材の締付トルク値が設定値以上であることを確認することができる。
In the mechanical preset torque wrench, when the tightening member is tightened, when the tightening torque reaches a set value, the compression force from the spring acts in the direction in which the toggle rotates around the connecting portion. . As the toggle rotates about the connecting portion, the toggle slides relative to the head portion. In the torque wrench, when the toggle slides with respect to the head portion and comes into contact with another part such as a case, sound and vibration are generated from the torque wrench. The operator can confirm that the tightening torque value of the tightening member is greater than or equal to the set value by sound or vibration generated from the torque wrench.
プレセット型トルクレンチでは、締付トルクの管理を行う場合に、締付箇所ごとに締付トルクの設定値を適切に設定する必要がある。
In the case of a preset torque wrench, when performing tightening torque management, it is necessary to appropriately set the tightening torque setting value for each tightening location.
なお、トルクレンチを用いた締付箇所の締付トルク管理技術において、特定された締付箇所の締付トルクの設定値をコンピュータからトルクレンチに送る技術が開示されている(例えば、特許文献1参照)。この技術では、トルクレンチに送られた設定値に基づいて、作業者は、トルクレンチの締付トルクを設定値の範囲内に収まるように調整した後に締付部材を締め付ける。
In addition, in a tightening torque management technique for a tightening location using a torque wrench, a technology is disclosed in which a set value of a tightening torque at a specified tightening location is sent from a computer to a torque wrench (for example, Patent Document 1). reference). In this technique, based on the set value sent to the torque wrench, the operator adjusts the tightening torque of the torque wrench to be within the range of the set value, and then tightens the tightening member.
しかし、特許文献1のトルクレンチでは、締付トルクの設定を作業者等がトルクレンチを操作して手動で行う必要があった。
However, in the torque wrench of Patent Document 1, it is necessary for an operator or the like to manually set the tightening torque by operating the torque wrench.
締付作業において、締付部材の締付トルクが適切な値であることを追跡可能にする、トレーサビリティ性を向上するには、トルクレンチに適切な締付トルクを設定することが求められる。また、締付作業のトレーサビリティを向上するには、その設定された締付トルクが容易に変更できないようにすることも求められる。

Further, in order to improve the traceability of the tightening operation, it is also required that the set tightening torque cannot be easily changed.
また、機械式のプレセット型トルクレンチは、測定精度を維持するためには、保管時にスプリングに加わる圧縮力を可能な限り(例えば、締付トルク値の設定範囲の原点位置まで)除荷するのが望ましい。
Further, in order to maintain the measurement accuracy, the mechanical preset torque wrench unloads the compression force applied to the spring during storage as much as possible (for example, to the origin position of the tightening torque value setting range). Is desirable.

FIG. 2 is a partial cross-sectional view showing an example of a
トルクレンチ10は、いわゆる機械式のプレセット型トルクレンチである。トルクレンチ10は、ケース11と、ヘッド部12と、ヘッドピン13と、トグル14と、接続部15と、保持部16と、スプリング17と、トルク値設定部18と、設定位置検出部19とを備える。
The torque wrench 10 is a so-called mechanical preset torque wrench. The torque wrench 10 includes a case 11, a head part 12, a head pin 13, a toggle 14, a connection part 15, a holding part 16, a spring 17, a torque value setting part 18, and a setting position detection part 19. Prepare.
ケース11は、ヘッド部12やトグル14などのトルクレンチ10の構成要素を収容し、トルクレンチ10の外形形状を構成する略筒状の部材である。ケース11は、一端にヘッド部12が設けられる。また、ケース11は、他端に作業者が把持するためのグリップ部11bが設けられる。
The case 11 is a substantially cylindrical member that houses the components of the torque wrench 10 such as the head portion 12 and the toggle 14 and constitutes the outer shape of the torque wrench 10. The case 11 is provided with a head portion 12 at one end. Further, the case 11 is provided with a grip portion 11b for the operator to hold at the other end.
ヘッド部12は、ラチェットヘッド12aとアーム部12bとリンク12cとを備える。ヘッド部12は、ラチェットヘッド12aとアーム部12bとの境界に設けられるヘッドピン13によって、ケース11に対して回動自在に軸支されている。
The head unit 12 includes a ratchet head 12a, an arm unit 12b, and a link 12c. The head portion 12 is pivotally supported with respect to the case 11 by a head pin 13 provided at the boundary between the ratchet head 12a and the arm portion 12b.
ラチェットヘッド12aは、ケース11から露出している。ラチェットヘッド12aには、締付部材と係合する不図示のソケットレンチ(ボルトまたはナット締付用)を、着脱自在に取り付けることができる。アーム部12bは、ケース11内部に収納される。アーム部12bは、ヘッドピン13を中心にケース11内部で揺動可能である。アーム部12bの先端には、トグル14と接続するリンク12cが設けられる。
The ratchet head 12a is exposed from the case 11. A socket wrench (not shown) that engages with a fastening member (for bolt or nut fastening) can be detachably attached to the ratchet head 12a. The arm portion 12b is housed inside the case 11. The arm portion 12 b can swing inside the case 11 around the head pin 13. A link 12c connected to the toggle 14 is provided at the tip of the arm portion 12b.
トグル14は、略矩形の板状部材である。トグル14は、一端がヘッド部12のリンク12cと接続し、他端が接続部15を介して保持部16と接続している。トグル14は、リンク12cによりケース11内部で揺動可能に軸支されている。
The toggle 14 is a substantially rectangular plate member. The toggle 14 has one end connected to the link 12 c of the head unit 12 and the other end connected to the holding unit 16 via the connection unit 15. The toggle 14 is pivotally supported inside the case 11 by a link 12c.
保持部16は、略円筒状の部材である。保持部16は、トルクレンチ10の軸方向(長手方向)に垂直な方向が平面となるように、ケース11内部に配置される。保持部16は、平面の一方には接続部15を介してトグル14の他端が摺動可能に接続している。保持部16は、平面の他方にはスプリング17の一方が接している。
The holding part 16 is a substantially cylindrical member. The holding part 16 is disposed inside the case 11 so that a direction perpendicular to the axial direction (longitudinal direction) of the torque wrench 10 is a plane. The other end of the toggle 14 is slidably connected to one side of the holding part 16 via the connection part 15. The holding portion 16 has one of the springs 17 in contact with the other flat surface.
スプリング17は、ケース11の内部のグリップ部11b寄りの位置に設けられる。スプリング17は、トルクレンチ10の長手方向が圧縮方向となる圧縮バネである。スプリング17には、例えばコイルばねを用いることができる。
The spring 17 is provided at a position near the grip portion 11 b inside the case 11. The spring 17 is a compression spring in which the longitudinal direction of the torque wrench 10 is the compression direction. As the spring 17, for example, a coil spring can be used.
トルク値設定部18は、例えばケース11のグリップ部11bの先端に設けられる。トルク値設定部18は、設定ボルト18aと、ストッパー18bと、頭部18cと、ロック部18dと、スプリング支持部18eとにより構成される。
The torque value setting portion 18 is provided at the tip of the grip portion 11b of the case 11, for example. The torque value setting unit 18 includes a setting bolt 18a, a stopper 18b, a head portion 18c, a lock portion 18d, and a spring support portion 18e.
図3は、トルクレンチ10のトルク値設定部18の付近を示す底面図である。図3に示すように、設定ボルト18aは、ストッパー18bに設けられる孔を貫通し、頭部18cのみがストッパー18bの外側に露出している。設定ボルト18aは、軸本体がケース11内部に収納されている。頭部18cには、歯車や六角穴などの被係合部が形成されている。頭部18cには、トルク値設定装置20に設けられる歯車や六角レンチなどの係合部と係合させることで設定ボルト18aを回動させることができる。
FIG. 3 is a bottom view showing the vicinity of the torque value setting unit 18 of the torque wrench 10. As shown in FIG. 3, the setting bolt 18a passes through a hole provided in the stopper 18b, and only the head 18c is exposed to the outside of the stopper 18b. The setting bolt 18 a has a shaft body housed inside the case 11. Engaged parts such as gears and hexagonal holes are formed on the head 18c. The setting bolt 18a can be rotated by engaging the head 18c with an engaging portion such as a gear or a hexagon wrench provided in the torque value setting device 20.
設定ボルト18aには、少なくとも一部に雄ネジのネジ山が切ってある。設定ボルト18aは、スプリング支持部18eに設けられる雌ネジに螺合している。ストッパー18bは、頭部18cが接することで設定ボルト18aの移動量を規制する。
設定 Male screw threads are cut at least partially on the setting bolt 18a. The setting bolt 18a is screwed into a female screw provided on the spring support 18e. The stopper 18b regulates the amount of movement of the setting bolt 18a by contacting the head 18c.
スプリング支持部18eは、ケース11の内側に設けられる接触面がスプリング17に接している。スプリング支持部18eは、保持部16の方向にスプリング17を圧縮する。トルク値設定部18は、頭部18cを回動させることで、設定ボルト18aが螺合しているスプリング支持部18eの位置が移動する。このため、トルク値設定部18は、スプリング17による保持部16に対する押圧力を変化させることができる。トルク値設定部18は、設定ボルト18aを回動操作することにより、スプリング17の圧縮度合いを調節し、締付トルク値を所定の値(例えば、締め付け箇所の締付部材ごとに定められる規定の締付トルク値)に設定可能である(図4及び図5参照)。
The contact surface provided inside the case 11 is in contact with the spring 17 in the spring support portion 18e. The spring support portion 18 e compresses the spring 17 in the direction of the holding portion 16. The torque value setting unit 18 moves the position of the spring support 18e to which the setting bolt 18a is screwed by rotating the head 18c. For this reason, the torque value setting unit 18 can change the pressing force of the spring 17 against the holding unit 16. The torque value setting unit 18 adjusts the degree of compression of the spring 17 by rotating the setting bolt 18a, and sets a tightening torque value to a predetermined value (for example, a prescribed value determined for each tightening member at the tightening point). (Tightening torque value) can be set (see FIGS. 4 and 5).
図2に戻り、ロック部18dは、ケース11のグリップ部11bの上端(ヘッド部12寄りの端部)に設けられる。ロック部18dは、設定ボルト18aを回動させてもトルク値設定部18の締付トルク値の変更ができないようにする。ロック部18dは、例えば、グリップ部11bと同軸に設けられるリング状の部材であり、トルクレンチ10の長手方向に沿ってケース11に対する相対的な位置を変更できる。
2, the lock portion 18d is provided at the upper end of the grip portion 11b of the case 11 (the end portion near the head portion 12). The lock portion 18d prevents the torque value setting portion 18 from changing the tightening torque value even if the setting bolt 18a is rotated. The lock portion 18d is, for example, a ring-shaped member provided coaxially with the grip portion 11b, and can change a relative position with respect to the case 11 along the longitudinal direction of the torque wrench 10.
設定位置検出部19は、例えばケース11の内部の設定ボルト18aの位置を検出することができるような位置に設けられる。設定位置検出部19は、設定ボルト18aや頭部18cの位置などを検出するセンサである。設定位置検出部19は、例えば画像により設定ボルト18aや頭部18cの位置などを検出するカメラや、赤外線など発光部と受光素子(フォトダイオード)との組み合わせなどにより構成される。設定位置検出部19は、検出した設定ボルト18aや頭部18cの位置などの情報を、無線または有線でトルク値設定装置20の制御部23に送信する。
The set position detector 19 is provided at a position where the position of the set bolt 18a inside the case 11 can be detected, for example. The set position detector 19 is a sensor that detects the position of the set bolt 18a and the head 18c. The setting position detection unit 19 includes, for example, a camera that detects the positions of the setting bolt 18a and the head 18c from an image, a combination of a light emitting unit such as infrared rays, and a light receiving element (photodiode). The setting position detection unit 19 transmits information such as the detected position of the setting bolt 18a and the head 18c to the control unit 23 of the torque value setting device 20 wirelessly or by wire.

以上説明したトルクレンチ10の動作について説明する。 [Torque wrench operation]
The operation of the
トルクレンチ10では、締付部材を締め付ける際に、締付トルクがトルク値設定部18により設定された設定値に達すると、スプリング17からの圧縮力がリンク12cを中心にトグル14が回動する方向に働く。トグル14がリンク12cを中心に回動することにより、トグル14は、ヘッド部12に対して摺動する。トルクレンチ10では、トグル14がヘッド部12に対して摺動してケース11など他の箇所に接触すると、トルクレンチ10から音と振動が発生する。
In the torque wrench 10, when the tightening member is tightened, when the tightening torque reaches the set value set by the torque value setting unit 18, the toggle force 14 rotates around the link 12c by the compression force from the spring 17. Work in the direction. The toggle 14 slides with respect to the head portion 12 as the toggle 14 rotates about the link 12c. In the torque wrench 10, sound and vibration are generated from the torque wrench 10 when the toggle 14 slides with respect to the head portion 12 and comes into contact with other parts such as the case 11.
トルクレンチ10では、トグル14がヘッド部12に対して摺動することで生ずる音と振動により、作業者に対して締付トルクが設定値に達したことを認識させることができる。
In the torque wrench 10, the operator can recognize that the tightening torque has reached the set value by the sound and vibration generated by the toggle 14 sliding with respect to the head portion 12.

Next, the configuration of the torque
図1に示すように、トルク値設定装置20は、接続部21と、駆動部22と、制御部23と、通信部24と、筐体25とを備える。
As shown in FIG. 1, the torque value setting device 20 includes a connection unit 21, a drive unit 22, a control unit 23, a communication unit 24, and a housing 25.
接続部21は、トルク値設定装置20にトルクレンチ10が取り付けられた状態でトルク値設定部18を操作可能な位置に設けられる。接続部21は、トルク値設定装置20に取り付けられたトルクレンチ10のトルク値設定部18と接続する。
The connection unit 21 is provided at a position where the torque value setting unit 18 can be operated in a state where the torque wrench 10 is attached to the torque value setting device 20. The connection unit 21 is connected to the torque value setting unit 18 of the torque wrench 10 attached to the torque value setting device 20.
図4は、トルク値設定装置20の接続部21の一例を示す模式図である。また、図5は、図1に示したトルク値設定装置20の接続部21の別の例を示す模式図である。
FIG. 4 is a schematic diagram illustrating an example of the connection portion 21 of the torque value setting device 20. FIG. 5 is a schematic diagram showing another example of the connecting portion 21 of the torque value setting device 20 shown in FIG.
図4及び図5に示すように、具体的には、接続部21は、例えば筐体25の収容部25aに設けられる。収容部25aは、トルクレンチ10のグリップ部11bを収容可能である。接続部21は、例えばトルク値設定部18の頭部18cの歯車や六角穴などの被係合部と係合可能な、図4に示す歯車や図5に示す六角レンチなどの係合部である。トルクレンチ10の頭部18cの被係合部に係合可能な係合部であることで、接続部21は、トルク値設定部18と接続可能である。
As shown in FIGS. 4 and 5, specifically, the connection portion 21 is provided in, for example, the housing portion 25 a of the housing 25. The accommodating portion 25 a can accommodate the grip portion 11 b of the torque wrench 10. The connecting portion 21 is an engaging portion such as a gear shown in FIG. 4 or a hexagon wrench shown in FIG. 5 that can be engaged with an engaged portion such as a gear of the head 18c of the torque value setting portion 18 or a hexagonal hole. is there. Since the engaging portion is engageable with the engaged portion of the head 18 c of the torque wrench 10, the connecting portion 21 can be connected to the torque value setting portion 18.
駆動部22は、例えばサーボモータやソレノイドなどのような、駆動量の制御が可能なアクチュエータである。駆動部22は、制御部23による制御に基づいた駆動量で接続部21を作動させる。
The drive unit 22 is an actuator capable of controlling the drive amount, such as a servo motor or a solenoid. The drive unit 22 operates the connection unit 21 with a drive amount based on control by the control unit 23.
制御部(制御基板)23は、通常、制御基板に実装される電子機器によりトルク値設定方法を実行して、トルク値設定装置の機能を実現する。制御部23は、例えば、締付トルク値の原点位置(任意の初期値、あるいはトルク値設定部18の設定範囲の限界位置)など、締付トルクを任意の設定値に設定する。つまり、制御部23は、接続部21、駆動部22とともに、原点設定部として機能する。制御部23は、駆動部22の駆動量を制御することによって接続部21を介してトルク値設定部18を操作する。制御部23は、トルクレンチ10の設定位置検出部19から送信された設定ボルト18aや頭部18cの位置情報に基づいてトルク値設定部18を操作することで、トルクレンチ10の締付トルクを設定値に設定する。
The control unit (control board) 23 usually executes a torque value setting method by an electronic device mounted on the control board to realize the function of the torque value setting device. For example, the control unit 23 sets the tightening torque to an arbitrary set value, such as an origin position of the tightening torque value (an arbitrary initial value or a limit position of the setting range of the torque value setting unit 18). That is, the control unit 23 functions as an origin setting unit together with the connection unit 21 and the drive unit 22. The control unit 23 operates the torque value setting unit 18 via the connection unit 21 by controlling the drive amount of the drive unit 22. The control unit 23 operates the torque value setting unit 18 based on the position information of the setting bolt 18 a and the head 18 c transmitted from the setting position detection unit 19 of the torque wrench 10, thereby adjusting the tightening torque of the torque wrench 10. Set to the set value.
通信部(通信モジュール)24は、例えばスマートフォン、タブレット端末、あるいはパーソナルコンピュータなどの情報処理装置30との間で、締付部材の締め付け箇所に対応した締付トルク値の情報を通信する。通信部24は、トルクレンチ10の設定位置検出部19から、送信された設定ボルト18aや頭部18cの位置情報を受信する。通信部24による通信路は、無線通信または有線通信の何れでもよい。また、通信部24と情報処理装置30との通信フォーマットの種類は限定されず、例えばBluetooth(登録商標)、赤外線通信、USB(Universal Serial Bus)、WAN(Wide Area Network)、LAN(Local Area Network)などを利用できる。
The communication unit (communication module) 24 communicates tightening torque value information corresponding to the tightening position of the tightening member with the information processing apparatus 30 such as a smartphone, a tablet terminal, or a personal computer. The communication unit 24 receives the transmitted position information of the setting bolt 18 a and the head 18 c from the setting position detection unit 19 of the torque wrench 10. The communication path by the communication unit 24 may be either wireless communication or wired communication. The type of communication format between the communication unit 24 and the information processing device 30 is not limited. For example, Bluetooth (registered trademark), infrared communication, USB (Universal Serial Bus), WAN (Wide Network Network), LAN (Local Network Network) ) Etc. can be used.
なお、トルク値設定装置20は、上述のように通信部24と情報処理装置30との通信により制御部23に締付トルク値を設定する以外に、例えば情報処理装置30のタッチパネルなどの入力部から通信部24を経て制御部23に設定値を入力させるようにしてもよい。
The torque value setting device 20 is not limited to setting the tightening torque value in the control unit 23 by communication between the communication unit 24 and the information processing device 30 as described above, and for example, an input unit such as a touch panel of the information processing device 30 The setting value may be input to the control unit 23 via the communication unit 24.
また、トルクレンチ10が、トルク値設定部18をロックするロック部18dを備える場合には、トルク値設定装置20は、ロック部18dを解除するロック操作部を備えていてもよい。ロック操作部は、トルク値設定装置20にセットされたトルクレンチ10のロック部18dを操作して、トルク値設定部18へのトルク値設定操作の受付可否を切り換える。
Further, when the torque wrench 10 includes the lock unit 18d that locks the torque value setting unit 18, the torque value setting device 20 may include a lock operation unit that releases the lock unit 18d. The lock operation unit operates the lock unit 18 d of the torque wrench 10 set in the torque value setting device 20 to switch whether to accept the torque value setting operation to the torque value setting unit 18.
また、トルク値設定装置20は、トルクレンチ10に設けられている設定位置検出部19を駆動部22の付近に備えてもよい。設定位置検出部19は、トルク値設定装置20に設けられる場合、例えばカメラであり、撮像した画像により設定ボルト18aなどの位置を検出する。
Further, the torque value setting device 20 may include a setting position detection unit 19 provided in the torque wrench 10 in the vicinity of the driving unit 22. When provided in the torque value setting device 20, the setting position detection unit 19 is a camera, for example, and detects the position of the setting bolt 18 a or the like from the captured image.

作業者によりトルクレンチ10がトルク値設定装置20の収容部25aにセットされると、制御部23は、リミットスイッチや光学センサなどの検出部によりトルクレンチ10が収容部25aにセットされたことを検出する。つまり、検出部は、トルク値設定部18とトルク値設定装置20の接続部21とが接続されたことを、トルク値設定部18とトルク値設定装置20の接続部21との接続状況として検出する。制御部23は、トルクレンチ10が収容部25aにセットされたことを検出した接続状況の記録を、日時などの情報とともに記憶部に記憶する。制御部23は、トルク値設定装置20により締付トルク値を設定するため、セットされたトルクレンチ10の機種を判定する(S101)。
When the operator sets the torque wrench 10 in the accommodating portion 25a of the torque value setting device 20, the control unit 23 confirms that the torque wrench 10 has been set in the accommodating portion 25a by a detection unit such as a limit switch or an optical sensor. To detect. That is, the detection unit detects that the torque value setting unit 18 and the connection unit 21 of the torque value setting device 20 are connected as a connection state between the torque value setting unit 18 and the connection unit 21 of the torque value setting device 20. To do. The control unit 23 stores, in the storage unit, a record of the connection status in which it is detected that the torque wrench 10 is set in the housing unit 25a together with information such as date and time. The control unit 23 determines the model of the set torque wrench 10 in order to set the tightening torque value by the torque value setting device 20 (S101).
機種を判定することにより、制御部23は、機種ごとに異なるトルクレンチ10において設定可能な締付トルクの範囲(例えば20~100N・m、40~200N・mなど)を設定する(S102)。
By determining the model, the control unit 23 sets a tightening torque range (for example, 20 to 100 N · m, 40 to 200 N · m, etc.) that can be set by the torque wrench 10 that is different for each model (S102).
情報処理装置30からトルク値設定装置20の通信部24に締付トルク値が送信されると、制御部23のメモリ部には、締付トルク値が入力される(S103)。なお、締付トルクの入力は、トルク値設定装置20に設けられる入力部から受け付けてもよい。
When the tightening torque value is transmitted from the information processing device 30 to the communication unit 24 of the torque value setting device 20, the tightening torque value is input to the memory unit of the control unit 23 (S103). The input of the tightening torque may be received from an input unit provided in the torque value setting device 20.
制御部(制御基板)23は、S102で決定された締付トルク値の範囲の情報に基づいて、締付トルク値をトルク値設定部18に設定するために必要な駆動部22の駆動量を演算する演算工程を実行する(S104)。
The control unit (control board) 23 sets the drive amount of the drive unit 22 necessary for setting the tightening torque value in the torque value setting unit 18 based on the information of the tightening torque value range determined in S102. A calculation step for calculation is executed (S104).
演算工程実行後、トルク値設定装置20には、トルクレンチ10のトルク値設定部18への締付トルク値の設定開始の操作が入力される(S105)。制御部23は、トルクレンチ10のトルク値設定部18の設定ボルト18aのロック部18dのロック状態を解除する処理を行う(S106)。
After execution of the calculation process, the torque value setting device 20 receives an operation for starting the setting of the tightening torque value to the torque value setting unit 18 of the torque wrench 10 (S105). The control unit 23 performs a process of releasing the lock state of the lock unit 18d of the setting bolt 18a of the torque value setting unit 18 of the torque wrench 10 (S106).
ロック状態を解除した後、制御部23は、設定値の設定前に設定値を任意の初期値、あるいはトルク値設定部18の設定範囲の限界位置(以下「原点位置」という。)に調整する処理を行う(S107)。原点位置の調整処理は、トルクレンチ10の設定値を正確に設定するための較正工程である。
After releasing the lock state, the control unit 23 adjusts the set value to an arbitrary initial value or the limit position of the set range of the torque value setting unit 18 (hereinafter referred to as “origin position”) before setting the set value. Processing is performed (S107). The origin position adjustment process is a calibration process for accurately setting the set value of the torque wrench 10.
設定値を原点位置に調整した後、制御部23は、締付トルク設定工程として、トルク値設定部18に締付トルク値を設定する(S108)。締付トルク値を設定するために、制御部23は、先に算出した駆動量で駆動部22を駆動し、トルク値設定部18を原点位置から締付トルク値に相当する位置まで駆動する。
After adjusting the set value to the origin position, the control unit 23 sets a tightening torque value in the torque value setting unit 18 as a tightening torque setting step (S108). In order to set the tightening torque value, the control unit 23 drives the drive unit 22 with the previously calculated drive amount, and drives the torque value setting unit 18 from the origin position to a position corresponding to the tightening torque value.
駆動部22によるトルク値の設定完了後、制御部23は、トルクレンチ10のトルク値設定部18の設定ボルト18aのロック部18dをロックする(S109)。ロック部18dのロック後、作業者によりトルクレンチ10が収容部25aから取り出されると、制御部23は、不図示の上記検出装置によりトルクレンチ10が収容部25aから取り出されたことを検出する。つまり制御部23は、トルク値設定部18と接続部21との接続の解除を検出する。制御部23は、トルク値設定部18と接続部21との接続の解除を検出した日時などの接続状況の情報を記憶部に記憶する。
After the setting of the torque value by the drive unit 22 is completed, the control unit 23 locks the lock unit 18d of the setting bolt 18a of the torque value setting unit 18 of the torque wrench 10 (S109). If the operator removes the torque wrench 10 from the accommodating portion 25a after locking the lock portion 18d, the control unit 23 detects that the torque wrench 10 has been removed from the accommodating portion 25a by the detection device (not shown). That is, the control unit 23 detects the release of the connection between the torque value setting unit 18 and the connection unit 21. The control unit 23 stores information on the connection status such as the date and time when the release of the connection between the torque value setting unit 18 and the connection unit 21 is detected in the storage unit.
以上説明したように、トルクレンチ10のトルク値設定システム1によれば、トルクレンチ10の締付トルク値をトルク値設定装置20により設定することができる。ここで、トルク値設定システム1は、トルクレンチ10のトルク値設定部18を接続部21により操作して、締付トルクの値を設定することができる。つまり、トルク値設定システム1によれば、作業者等がトルク値設定部18を操作することなく、所定の締付トルク値の設定を行うことができる。
As described above, according to the torque value setting system 1 of the torque wrench 10, the tightening torque value of the torque wrench 10 can be set by the torque value setting device 20. Here, the torque value setting system 1 can set the value of the tightening torque by operating the torque value setting unit 18 of the torque wrench 10 with the connection unit 21. That is, according to the torque value setting system 1, a predetermined tightening torque value can be set without an operator or the like operating the torque value setting unit 18.
また、トルク値設定システム1によれば、作業者等がトルク値設定部18を操作する必要がないため、確実に規定の締付トルク値で締付部材を締め付けさせることができる。また、トルク値設定システム1によれば、制御部23は、トルクレンチ10が収容部25aから取り出されたことを検出した日時などの情報を記憶部に記憶することができる。
Further, according to the torque value setting system 1, it is not necessary for an operator or the like to operate the torque value setting unit 18, so that the tightening member can be securely tightened with a specified tightening torque value. Further, according to the torque value setting system 1, the control unit 23 can store information such as the date and time when it is detected that the torque wrench 10 has been taken out from the storage unit 25 a in the storage unit.
従って、トルク値設定システム1によれば、締付部材の締付トルクを適切に管理して、締付トルクの管理のトレーサビリティを向上することができる。
Therefore, according to the torque value setting system 1, it is possible to appropriately manage the tightening torque of the tightening member and improve the traceability of the tightening torque management.
また、トルク値設定システム1は、トルクレンチ10のトルク値設定部18を接続部21により操作して、トルク値設定部18に設定される締付トルク値を、原点位置を含めて任意の位置に設定することができる。
In addition, the torque value setting system 1 operates the torque value setting unit 18 of the torque wrench 10 with the connection unit 21 to set the tightening torque value set in the torque value setting unit 18 to any position including the origin position. Can be set to
従って、トルク値設定システム1によれば、機械式のプレセット型トルクレンチの測定精度を維持することができる。
Therefore, according to the torque value setting system 1, the measurement accuracy of the mechanical preset torque wrench can be maintained.
