Description
本発明は、螺子等の螺合部材を適正なトルクで締め付ける練習に用いられる締め付けトルク練習機に関する。 The present invention relates to a tightening torque practice machine used for practice of tightening a screw member such as a screw with an appropriate torque.
ボルトやナット、螺子等の螺合部材を、スパナやレンチ、ドライバー等の締め付け工具で締め付ける際には、螺合部材に対して適正なトルクが掛かるように締め付け工具に力を加える。ところが、力を加える際の作業者の感覚だけを頼りにすると、作業者の技能の水準が低い場合等に適正なトルクを得るのが難しい。 When tightening a screwing member such as a bolt, a nut, or a screw with a tightening tool such as a spanner, a wrench, or a screwdriver, a force is applied to the tightening tool so that an appropriate torque is applied to the screwing member. However, relying only on the feeling of the worker when applying force makes it difficult to obtain an appropriate torque when the level of skill of the worker is low.
そのため、常に適正なトルクを得られるように、いわゆるトルクレンチ等と呼ばれる締め付け工具が用いられている（例えば、特許文献１，２参照）。トルクレンチには、設定したトルクに達すると音が鳴るシグナル式トルクレンチや、空転する空転式トルクレンチ、トルクの値を表示できる直読式トルクレンチ等がある。 Therefore, a tightening tool called a so-called torque wrench or the like is used so that an appropriate torque can always be obtained (see, for example, Patent Documents 1 and 2). The torque wrench includes a signal type torque wrench that makes a sound when a set torque is reached, an idle type torque wrench that idles, and a direct reading type torque wrench that can display a torque value.
しかしながら、トルクを確認できるトルクレンチ等の締め付け工具は、当該機能の無い通常の締め付け工具に比べて大きく、狭い空間での作業に向かない。よって、例えば、装置内のような狭い空間では、トルクレンチ等を使用できないことがあった。その場合、通常の締め付け工具を用いることになるので、作業者には高い水準の技能が求められる。 However, a tightening tool such as a torque wrench that can confirm the torque is larger than a normal tightening tool without the function, and is not suitable for work in a narrow space. Therefore, for example, a torque wrench or the like may not be used in a narrow space such as the inside of the device. In that case, since a normal tightening tool is used, the worker is required to have a high level of skill.
本発明はかかる問題点に鑑みてなされたものであり、その目的とするところは、螺合部材を適正なトルクで締め付ける練習に適した締め付けトルク練習機を提供することである。 The present invention has been made in view of such problems, and an object of the present invention is to provide a tightening torque practice machine suitable for practice of tightening a screw member with an appropriate torque.
本発明の一態様によれば、締め付け工具を用いて螺合部材を適正なトルクで締め付ける練習に用いられる締め付けトルク練習機であって、一端に螺合部材が着脱自在に装着される回転軸と、該回転軸の他端に連結されるトルク計測器と、該回転軸に装着された該螺合部材に係合し、練習者による締め付けのトルクを該螺合部材に伝える締め付け工具と、該螺合部材から該回転軸に作用し該トルク計測器によって計測されるトルクに基づく情報の処理を行う制御ユニットと、該トルク計測器によって計測される該トルクが適正であるか否かを表示する表示装置と、を備え、該制御ユニットは、締め付けが適正に行われるトルクに関する情報が記憶されるトルク情報記憶部を含む締め付けトルク練習機が提供される。 According to one aspect of the present invention, there is provided a tightening torque practice machine used for practice of tightening a screwing member with an appropriate torque by using a tightening tool, the rotating shaft having a screwing member detachably attached to one end thereof. A torque measuring device connected to the other end of the rotating shaft, a tightening tool that engages with the screwing member mounted on the rotating shaft, and transmits torque of tightening by a trainee to the screwing member, A control unit that acts on the rotary shaft from the screw member and processes information based on the torque measured by the torque measuring device, and displays whether or not the torque measured by the torque measuring device is appropriate. There is provided a display device, and the control unit is provided with a tightening torque training machine that includes a torque information storage unit that stores information about torque at which tightening is properly performed .
また、本発明の一態様に係る締め付けトルク練習機において、該回転軸、該トルク計測器、該締め付け工具、及び該表示装置を収容する収容ケースを更に備え、該収容ケースには、該収容ケースの持ち運びを可能とする持ち手部が設けられていることが好ましい。 The tightening torque practice machine according to one aspect of the present invention further includes a housing case that houses the rotary shaft, the torque measuring device, the tightening tool, and the display device, and the housing case includes the housing case. It is preferable that a handle portion is provided to enable carrying the.
本発明の一態様に係る締め付けトルク練習機には、締め付け工具から螺合部材に伝わるトルクを計測するトルク計測器と、トルク計測器によって計測されるトルクが適正であるか否かを表示する表示装置とが設けられているので、螺合部材に伝わるトルクが適正か否かを確認しながら締め付けの練習を行える。このように、本発明の一態様に係る締め付けトルク練習機は、螺合部材を適正なトルクで締め付ける練習に適している。 In the tightening torque practice machine according to one aspect of the present invention, a torque measuring device that measures the torque transmitted from the tightening tool to the screwing member and a display that displays whether or not the torque measured by the torque measuring device is appropriate. Since the device is provided, it is possible to practice tightening while confirming whether or not the torque transmitted to the screwing member is appropriate. Thus, the tightening torque practice machine according to one aspect of the present invention is suitable for practice of tightening the screwing member with an appropriate torque.
添付図面を参照して、本発明の一態様に係る実施形態について説明する。図１は、本実施形態に係る締め付けトルク練習機の外観を模式的に示す斜視図である。図１に示すように、締め付けトルク練習機２は、各構造を支持する直方体状の基台４を備えている。基台４の後方側の領域には、上方に向かって伸長する支持構造６が設けられている。 An embodiment according to an aspect of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view schematically showing the appearance of the tightening torque training machine according to the present embodiment. As shown in FIG. 1, the tightening torque practice machine 2 includes a rectangular parallelepiped base 4 that supports each structure. A support structure 6 extending upward is provided in a region on the rear side of the base 4.
支持構造６の前方で露出する基台４の上面４ａ側には、六角レンチやドライバー等の締め付け工具８を収容するための第１収容部１０が形成されている。第１収容部１０は、例えば、基台４の前面（正面）に向かって右側に形成された凹状の第１収容領域１０ａと、基台４の前面に向かって左側に形成された凹状の第２収容領域１０ｂとを含む。 A first accommodating portion 10 for accommodating a tightening tool 8 such as a hexagon wrench or a screwdriver is formed on the upper surface 4a side of the base 4 exposed in front of the support structure 6. The first accommodating portion 10 includes, for example, a concave first accommodating area 10a formed on the right side of the front surface (front surface) of the base 4, and a concave first accommodating area 10a formed on the left side of the front surface of the base 4. 2 accommodation areas 10b are included.
第１収容領域１０ａには、複数の六角レンチ８ａが収容されている。一方で、第２収容領域１０ｂには、複数のドライバー８ｂが収容されている。なお、第１収容部１０の構成や、収容する締め付け工具８の種類等に制限はない。例えば、１つ、又は３つ以上の収容領域からなる第１収容部１０を形成しても良い。 A plurality of hexagonal wrenches 8a are housed in the first housing area 10a. On the other hand, a plurality of drivers 8b are stored in the second storage area 10b. There is no limitation on the configuration of the first accommodating portion 10, the type of the tightening tool 8 to be accommodated, and the like. For example, you may form the 1st accommodating part 10 which consists of one or three or more accommodating areas.
第１収容領域１０ａと第２収容領域１０ｂとの間の領域（中央の領域）には、締め付けのトルクを測定するための測定部１２が設けられている。測定部１２は、例えば、上端（一端）側が基台４の上面４ａに露出する回転軸１４と、回転軸１４の下端（他端）側に連結されるトルク計測器１６とを含む。 A measuring unit 12 for measuring the tightening torque is provided in a region (central region) between the first accommodation region 10a and the second accommodation region 10b. The measurement unit 12 includes, for example, a rotating shaft 14 whose upper end (one end) side is exposed on the upper surface 4a of the base 4, and a torque measuring device 16 connected to the lower end (other end) side of the rotating shaft 14.
図２は、本実施形態に係る締め付けトルク練習機２を使用する際の測定部１２の状態について説明するための斜視図であり、図３は、締め付けトルク練習機２を使用する際の測定部１２の状態を模式的に示す図である。図２及び図３に示すように、回転軸１４の上端側には、第１締結部材（ビット）１８と係合する円柱状の受け部１４ａが設けられている。 FIG. 2 is a perspective view for explaining the state of the measurement unit 12 when using the tightening torque practice machine 2 according to the present embodiment, and FIG. 3 is a measurement unit when using the tightening torque practice machine 2. It is a figure which shows the state of 12 typically. As shown in FIGS. 2 and 3, on the upper end side of the rotary shaft 14, a cylindrical receiving portion 14 a that engages with the first fastening member (bit) 18 is provided.
この受け部１４ａには、受け部１４ａの上面を正方形状に開口する凹部１４ｂが形成されている。第１締結部材１８は、例えば、円柱状に形成されており、その下端には、凹部１４ｂの形状に対応する四角柱状の凸部１８ａが設けられている。凸部１８ａを受け部１４ａの凹部１４ｂに嵌め込むことで、回転軸１４に対して第１締結部材１８を連結できる。 The receiving portion 14a is formed with a recess 14b that opens the upper surface of the receiving portion 14a in a square shape. The first fastening member 18 is formed, for example, in a columnar shape, and a rectangular columnar convex portion 18a corresponding to the shape of the concave portion 14b is provided at the lower end thereof. The first fastening member 18 can be connected to the rotating shaft 14 by fitting the convex portion 18a into the concave portion 14b of the receiving portion 14a.
第１締結部材１８の上面１８ｂには、円盤状の第２締結部材２０が重ねられる。第２締結部材２０には、第２締結部材２０を第１面２０ａから第２面２０ｂまで貫通する螺子穴２０ｃが形成されている。また、第１締結部材１８の上面１８ｂ側には、第２締結部材２０の螺子穴２０ｃに対応する螺子穴１８ｃが形成されている。 A disc-shaped second fastening member 20 is superposed on the upper surface 18b of the first fastening member 18. The second fastening member 20 is formed with a screw hole 20c that penetrates the second fastening member 20 from the first surface 20a to the second surface 20b. A screw hole 18c corresponding to the screw hole 20c of the second fastening member 20 is formed on the upper surface 18b side of the first fastening member 18.
例えば、第１締結部材１８の上面１８ｂに第２締結部材２０の第２面２０ｂを重ねた状態で、螺子穴１８ｃ，２０ｃには、螺子等の螺合部材２２が回転、挿入される。つまり、螺合部材２２によって、第１締結部材１８と第２締結部材２０とが結合される。なお、図２及び図３では、頭部２２ａに六角穴が形成された六角穴付ボルトを螺合部材２２として用いている。 For example, a screwing member 22 such as a screw is rotated and inserted into the screw holes 18c and 20c with the second surface 20b of the second fastening member 20 superposed on the upper surface 18b of the first fastening member 18. That is, the first fastening member 18 and the second fastening member 20 are joined by the screwing member 22. Note that, in FIGS. 2 and 3, a hexagon socket head cap screw having a hexagonal hole formed in the head portion 22 a is used as the screwing member 22.
螺合部材２２を締め付ける際には、螺合部材２２に締め付け工具８を係合させて、この締め付け工具８を、例えば、時計回りに回転させる。図２及び図３では、螺合部材２２として六角穴付ボルトを用いるので、締め付け工具８としては、六角レンチ８ａが用いられる。螺合部材２２の締め付けによって発生するトルクは、回転軸１４を介してトルク計測器１６に伝わる。 When tightening the screwing member 22, the tightening tool 8 is engaged with the screwing member 22, and the tightening tool 8 is rotated clockwise, for example. Since a hexagon socket head cap screw is used as the screwing member 22 in FIGS. 2 and 3, a hexagon wrench 8 a is used as the tightening tool 8. The torque generated by tightening the screwing member 22 is transmitted to the torque measuring device 16 via the rotating shaft 14.
支持構造６の下部６ａの前面（正面）側には、第１締結部材１８や第２締結部材２０、螺合部材２２等を収容するための第２収容部２４が形成されている。第２収容部２４は、例えば、支持構造６の前面に向かって右側に形成された複数の第１締結部材収容領域２４ａを含む。各第１締結部材収容領域２４ａには、例えば、Ｍ２，Ｍ３，Ｍ４，Ｍ５，Ｍ６等のサイズ（呼び径）に対応する第１締結部材（ビット）１８が収容される。 A second accommodating portion 24 for accommodating the first fastening member 18, the second fastening member 20, the screwing member 22 and the like is formed on the front surface (front surface) side of the lower portion 6a of the support structure 6. The second accommodating portion 24 includes, for example, a plurality of first fastening member accommodating regions 24a formed on the right side of the front surface of the support structure 6. The first fastening member (bit) 18 corresponding to the size (nominal diameter) of, for example, M2, M3, M4, M5, M6 is housed in each first fastening member housing region 24a.
第１締結部材収容領域２４ａの左側には、複数の第２締結部材収容領域２４ｂが形成されている。各第２締結部材収容領域２４ｂには、例えば、ＰＶＣ、アルミニウム（アルミ）、ステンレス（ＳＵＳ）等の材料で形成され、Ｍ２，Ｍ３，Ｍ４，Ｍ５，Ｍ６等のサイズ（呼び径）にそれぞれ対応する第２締結部材２０が収容される。 A plurality of second fastening member accommodation regions 24b are formed on the left side of the first fastening member accommodation region 24a. Each second fastening member accommodating region 24b is formed of a material such as PVC, aluminum (aluminum), and stainless steel (SUS), and corresponds to the size (nominal diameter) of M2, M3, M4, M5, M6, etc., respectively. The second fastening member 20 is accommodated.
また、第２締結部材収容領域２４ｂの左側には、複数の螺合部材収容領域２４ｃが形成されている。各螺合部材収容領域２４ｃには、例えば、Ｍ２，Ｍ３，Ｍ４，Ｍ５，Ｍ６等のサイズ（呼び径）にそれぞれ対応するトラス螺子（トラス）、六角ボルト（六角頭）、六角穴付ボルト（六角穴）等の螺合部材２２が収容される。なお、第２収容部２４の構成等に制限はない。 A plurality of screw member accommodating areas 24c are formed on the left side of the second fastening member accommodating area 24b. In each screw member accommodating area 24c, for example, a truss screw (truss), a hexagonal bolt (hexagonal head), a hexagon socket head bolt (corresponding to a size (nominal diameter) of M2, M3, M4, M5, M6, etc., respectively. A screwing member 22 such as a hexagonal hole) is housed. It should be noted that there is no limitation on the configuration or the like of the second storage portion 24.
支持構造６の上部６ａの前面（正面）側には、トルク計測器１６で計測されたトルクが適正であるか否かを表示するためのタッチパネル（表示装置、入力装置）２６が設けられている。なお、このタッチパネル２６は、締め付けトルク練習機２に対して各種の情報を入力する際にも使用される。 A touch panel (display device, input device) 26 for displaying whether or not the torque measured by the torque measuring device 16 is appropriate is provided on the front surface (front surface) of the upper portion 6a of the support structure 6. .. The touch panel 26 is also used when inputting various information to the tightening torque practice machine 2.
図４は、締め付けトルク練習機２で行われる情報処理の例を説明するための機能ブロック図であり、図５（Ａ）及び図５（Ｂ）は、タッチパネル２６に表示される画像の例を模式的に示す図である。図４に示すように、トルク計測器１６及びタッチパネル２６は、各種の情報処理を行う制御ユニット（制御装置）２８に接続されている。 FIG. 4 is a functional block diagram for explaining an example of information processing performed by the tightening torque practice machine 2, and FIGS. 5A and 5B are examples of images displayed on the touch panel 26. It is a figure which shows typically. As shown in FIG. 4, the torque measuring device 16 and the touch panel 26 are connected to a control unit (control device) 28 that performs various types of information processing.
タッチパネル２６には、制御ユニット２８の情報処理部２８ａから送られる表示情報に基づいて、図５（Ａ）に示すような計測用の画像３０が表示される。この画像３０の上部には、例えば、練習者の氏名や識別コード等の情報を入力するための第１入力欄３０ａ、締め付けの練習に使用される第２締結部材２０や螺合部材２２の情報を入力するための第２入力欄３０ｂが設けられている。 On the touch panel 26, a measurement image 30 as shown in FIG. 5A is displayed based on the display information sent from the information processing unit 28a of the control unit 28. In the upper part of this image 30, for example, information on the first input field 30a for inputting information such as the name and identification code of the practitioner, information on the second fastening member 20 and the screwing member 22 used for the practice of tightening. A second input field 30b for inputting is input.
練習を開始する前には、練習者に関する情報を第１入力欄３０ａに入力し、第２締結部材２０や螺合部材２２に関する情報を第２入力欄３０ｂに入力する。各種情報の入力は、例えば、画像３０の下部に配置されたソフトウェアキーボード３０ｃを用いて行うことができる。 Before the practice is started, information about the practitioner is input to the first input field 30a, and information about the second fastening member 20 and the screwing member 22 is input to the second input field 30b. Various information can be input using, for example, a software keyboard 30c arranged below the image 30.
第１入力欄３０ａに入力された情報及び第２入力欄３０ｂに入力された情報は、制御ユニット２８の情報処理部２８ａへと送られる。情報処理部２８ａは、入力された練習者に関する情報を練習者情報記憶部２８ｂに記憶させる。また、情報処理部２８ａは、入力された第２締結部材２０に関する情報を締結部材情報記憶部２８ｃに記憶させ、螺合部材２２に関する情報を螺合部材情報記憶部２８ｄに記憶させる。 The information input to the first input field 30a and the information input to the second input field 30b are sent to the information processing section 28a of the control unit 28. The information processing unit 28a stores the input information about the practitioner in the practitioner information storage unit 28b. Further, the information processing unit 28a stores the input information about the second fastening member 20 in the fastening member information storage unit 28c and stores the information about the screwing member 22 in the screwing member information storage unit 28d.
更に、情報処理部２８ａは、第２締結部材２０や螺合部材２２の情報に基づいて、締め付けが適正に行われるトルク（以下、適正トルク）に関する情報を適正トルク情報記憶部２８ｅから取得する。なお、この適正トルク情報記憶部２８ｅには、第２締結部材２０や螺合部材２２の組み合わせに応じた適正トルクに関する情報（例えば、適正トルクの範囲を示す情報）が予め記憶されている。 Further, the information processing unit 28a acquires information on the torque (hereinafter, referred to as appropriate torque) at which the tightening is appropriately performed from the appropriate torque information storage unit 28e based on the information on the second fastening member 20 and the screwing member 22. The proper torque information storage unit 28e stores in advance information about proper torque (for example, information indicating a range of proper torque) according to the combination of the second fastening member 20 and the screwing member 22.
この状態で、練習者による締め付けが開始される。具体的には、螺合部材２２に締め付け工具８を係合させた上で、この締め付け工具８を、例えば、時計回りに回転させる。締め付け工具８によって練習者から螺合部材２２に伝えられた締め付けのトルクは、螺合部材２２、第２締結部材２０、第１締結部材１８等を介して回転軸１４に作用し、トルク計測器１６で計測される。 In this state, the practitioner starts tightening. Specifically, the tightening tool 8 is engaged with the screw member 22, and then the tightening tool 8 is rotated, for example, in the clockwise direction. The tightening torque transmitted from the practitioner to the screwing member 22 by the tightening tool 8 acts on the rotating shaft 14 via the screwing member 22, the second fastening member 20, the first fastening member 18, etc. Measured at 16.
トルク計測器１６で計測されたトルク（以下、計測トルク）の値は、制御ユニット２８の情報処理部２８ａへと送られる。情報処理部２８ａは、計測トルクの値を、例えば、練習者情報記憶部２８ｂに記憶されている練習者に関する情報とともに、測定結果記憶部２８ｆに記憶させる。 The value of the torque (hereinafter, measured torque) measured by the torque measuring device 16 is sent to the information processing unit 28a of the control unit 28. The information processing unit 28a stores the value of the measured torque in the measurement result storage unit 28f together with, for example, the information about the trainee stored in the trainee information storage unit 28b.
また、情報処理部２８ａは、計測トルクの値を、例えば、画像３０の中央に配置されている測定値表示欄３０ｄに表示させる。更に、情報処理部２８ａは、例えば、計測トルクの値と、適正トルク情報記憶部２８ｅから取得した適正トルクに関する情報と、に基づいて、計測トルクと適正トルクとの関係を視覚的に示す帯状のゲージ３０ｅを表示させる。 The information processing unit 28a also displays the value of the measured torque in the measured value display field 30d arranged in the center of the image 30, for example. Further, the information processing unit 28a has, for example, a strip shape visually showing the relationship between the measured torque and the proper torque based on the value of the measured torque and the information about the proper torque acquired from the proper torque information storage unit 28e. Display the gauge 30e.
なお、ゲージ３０ｅ内では、表示マーク３０ｆによって適正トルクに対する計測トルクのおおよその関係が示されている。よって、練習者は、測定値表示欄３０ｄやゲージ３０ｅを見ることで、螺合部材２２を適正トルクで締め付けることができたか否かを容易に確認できる。 In the gauge 30e, the display mark 30f indicates an approximate relationship between the proper torque and the measured torque. Therefore, the practitioner can easily confirm whether or not the screw member 22 can be tightened with an appropriate torque by looking at the measurement value display column 30d and the gauge 30e.
情報処理部２８ａは、計測トルクが適正トルクの範囲内である場合等に、その旨を示す情報を測定結果記憶部２８ｆに記憶させると良い。このように、各練習者の成績を蓄積させることで、例えば、図５（Ｂ）の画像３２に示すように、複数の練習者の成績を比較可能な態様で表示できる。 When the measured torque is within the range of the proper torque, the information processing unit 28a may store information indicating that fact in the measurement result storage unit 28f. In this way, by accumulating the results of each practitioner, the results of a plurality of practitioners can be displayed in a comparable manner, for example, as shown in the image 32 of FIG. 5(B).
以上のように、本実施形態に係る締め付けトルク練習機２には、締め付け工具８から螺合部材２２に伝わるトルクを計測するトルク計測器１６と、トルク計測器１６によって計測されるトルクが適正であるか否かを表示するタッチパネル（表示装置）２６とが設けられているので、螺合部材２２に伝わるトルクが適正か否かを確認しながら締め付けの練習を行える。このように、本実施形態に係る締め付けトルク練習機２は、螺合部材２２を適正なトルクで締め付ける練習に適している。 As described above, in the tightening torque practice machine 2 according to the present embodiment, the torque measuring device 16 that measures the torque transmitted from the tightening tool 8 to the screwing member 22 and the torque measured by the torque measuring device 16 are appropriate. Since a touch panel (display device) 26 for displaying whether or not there is is provided, it is possible to practice tightening while confirming whether or not the torque transmitted to the screwing member 22 is appropriate. As described above, the tightening torque practice machine 2 according to the present embodiment is suitable for practice of tightening the screwing member 22 with an appropriate torque.
なお、本発明は上記実施形態の記載に限定されず、種々変更して実施可能である。例えば、上記実施形態に係る締め付けトルク練習機２では、同じ材質でなる複数の第１締結部材１８を選択的に用いているが、第１締結部材１８の材質等を変更することもできる。その場合には、第２締結部材２０に関する情報とともに、第１締結部材１８に関する情報を入力して利用できるように制御ユニット２８等を構成することが望ましい。 It should be noted that the present invention is not limited to the description of the above embodiment, and can be implemented with various modifications. For example, in the tightening torque training machine 2 according to the above embodiment, the plurality of first fastening members 18 made of the same material are selectively used, but the material of the first fastening members 18 and the like can be changed. In that case, it is desirable to configure the control unit 28 and the like so that the information about the first fastening member 18 can be input and used together with the information about the second fastening member 20.
また、計測トルクが適正トルクの範囲内であるか否かを制御ユニット２８等が判定しても良い。この場合には、ゲージ３０ｅ等に代えて、判定の結果を表示することができる。もちろん、ゲージ３０ｅ等とともに判定の結果を表示しても良い。 Further, the control unit 28 or the like may determine whether the measured torque is within the proper torque range. In this case, the result of the determination can be displayed instead of the gauge 30e or the like. Of course, the determination result may be displayed together with the gauge 30e and the like.
また、上記実施形態では、据え置きタイプの締め付けトルク練習機２について説明しているが、本発明に係る締め付けトルク練習機は、持ち運び可能なポータブルタイプでも良い。図６は、変形例に係る締め付けトルク練習機の外観を示す斜視図である。なお、以下では、上記実施形態のトルク練習機２と共通する構成要素に同じ符号を付して、各構成要素の詳細な説明を省略する。 Further, in the above embodiment, the stationary type tightening torque training machine 2 is described, but the tightening torque training machine according to the present invention may be a portable type that can be carried. FIG. 6 is a perspective view showing the appearance of a tightening torque training machine according to a modification. In addition, below, the same code|symbol is attached|subjected to the component common to the torque practice machine 2 of the said embodiment, and detailed description of each component is abbreviate|omitted.
図６に示すように、変形例に係る締め付けトルク練習機４２は、基台４や支持構造６の代わりに直方体状の収容ケース４４を備えている。この収容ケース４４は、厚みが約半分である第１収容ケース４６と第２収容ケース４８とを含んでいる。第１収容ケース４６の一端側と第２収容ケース４８の一端側とは、蝶番等の連結具（不図示）を介して連結されている。よって、例えば、連結具を回転の中心として、第１収容ケース４６と第２収容ケース４８との一方に対して他方を回転させることで、収容ケース４４を開閉できる。 As shown in FIG. 6, the tightening torque practice machine 42 according to the modified example includes a rectangular parallelepiped housing case 44 instead of the base 4 and the support structure 6. The storage case 44 includes a first storage case 46 and a second storage case 48, each of which has a thickness of about half. One end side of the first storage case 46 and one end side of the second storage case 48 are connected via a connecting tool (not shown) such as a hinge. Therefore, for example, the housing case 44 can be opened and closed by rotating one of the first housing case 46 and the second housing case 48 with respect to the other with the connector as the center of rotation.
収容ケース４４を閉じた状態で第２収容ケース４８に対面する第１収容ケース４６の内面４６ａ側には、締め付け工具８を収容するための第１収容部１０、トルクを測定するための測定部１２、第１締結部材１８や第２締結部材２０、螺合部材２２等を収容するための第２収容部２４が形成されている。一方で、収容ケース４４を閉じた状態で第１収容ケース４６に対面する第２収容ケース４８の内面４８ａ側には、タッチパネル（表示装置、入力装置）２６が設けられている。 On the inner surface 46a side of the first accommodating case 46 facing the second accommodating case 48 with the accommodating case 44 closed, the first accommodating portion 10 for accommodating the tightening tool 8 and the measuring portion for measuring torque. A second accommodating portion 24 for accommodating the first fastening member 18, the second fastening member 20, the screwing member 22, and the like is formed. On the other hand, a touch panel (display device, input device) 26 is provided on the inner surface 48a side of the second housing case 48 that faces the first housing case 46 with the housing case 44 closed.
第１収容ケース４６と第２収容ケース４８との他端側には、収容ケース４４を閉じた状態に維持するための留め具５０ａ，５０ｂが設けられている。例えば、収容ケース４４を閉じた上で、留め具５０ａに対して留め具５０ｂを係合させれば、搬送中に収容ケース４４が開いてしまうことはなくなる。 Fasteners 50a and 50b for keeping the storage case 44 in a closed state are provided on the other end sides of the first storage case 46 and the second storage case 48. For example, by closing the storage case 44 and then engaging the fastener 50b with the fastener 50a, the storage case 44 will not be opened during transportation.
また、第１収容ケース４６の他端側には、収容ケース４４の容易な持ち運びを可能にするための持ち手（持ち手部）５２が設けられている。なお、この持ち手の配置や形状等に制限はなく、例えば、第２収容ケース４８の他端側に持ち手を設けることもできる。もちろん、第１収容ケース４６及び第２収容ケース４８の両方に持ち手を設けても良い。 A handle 52 is provided on the other end side of the first housing case 46 to enable easy carrying of the housing case 44. There is no limitation on the arrangement or shape of the handle, and for example, the handle may be provided on the other end side of the second housing case 48. Of course, handles may be provided on both the first storage case 46 and the second storage case 48.
その他、上記実施形態に係る構造、方法等は、本発明の目的の範囲を逸脱しない限りにおいて適宜変更して実施できる。 In addition, the structures, methods, and the like according to the above-described embodiments can be appropriately modified and implemented without departing from the scope of the object of the present invention.
