【考案の詳細な説明】
本考案は、大型ナツトの締付けに際し、特に被螺挿物が
回転可能な筒状体である場合に使用しうる締付装置に関
する。[Detailed Description of the Invention] The present invention relates to a tightening device that can be used when tightening a large nut, particularly when the object to be screwed is a rotatable cylindrical body.
例えばロール・スリーブのような大型円筒体に対して大
型ナツトを螺挿して締付ける場合、従来は固定させたス
リーブに対してナツトを係合し、治具やバールなどを使
用してナツトを回転させる人力による締付けを行なって
いた。For example, when screwing a large nut into a large cylindrical body such as a roll sleeve and tightening it, conventionally the nut is engaged with a fixed sleeve and rotated using a jig or crowbar. Tightening was done manually.
しかしながらナツトが大型であるために作業自体が重労
働になり、能率も低下する実情にありtう
本考案の目的は、このような従来の不都合を解消させる
ことであり、能率的な大型ナツトの締付手段を提供する
ことにある。However, due to the large size of the nut, the work itself becomes labor intensive and efficiency decreases.The purpose of the present invention is to eliminate these conventional inconveniences, and to develop an efficient method for tightening large nuts. The objective is to provide a means of attachment.
本考案の締付装置は一端につばを有し他端にねじ部を有
する被螺挿物(以下スリーブとする)aを装着して回転
せしめる保持装置1と、ナラ)bを保持するナツト受台
装置2と、前記ナツト受台装置2と組合ってナラ)bを
締付方向へ移動せしめるナツト固定装置3とから成る。The tightening device of the present invention consists of a holding device 1 for mounting and rotating a threaded object (hereinafter referred to as a sleeve) a having a collar at one end and a threaded portion at the other end, and a nut receiver for holding a nut b. The nut fixing device 3 is comprised of a stand device 2 and a nut fixing device 3 that is combined with the nut holder device 2 to move the nut b in the tightening direction.
スリーブ保持装置1は、第1図に示すように水平に配置
した回転軸11をハウジング12によって所定の高さに
回転可能に保持させたことを主要構成とするものであっ
て、回転軸11は、一端の突出側にスリーブaを密嵌装
着しうる取付部13を一体に形成してあり、他端には摩
擦クラッチ14を介在して、モータ15を接続しである
。As shown in FIG. 1, the main structure of the sleeve holding device 1 is that a horizontally arranged rotating shaft 11 is rotatably held at a predetermined height by a housing 12. A mounting portion 13 into which the sleeve a can be tightly fitted is integrally formed on the protruding side of one end, and a motor 15 is connected to the other end with a friction clutch 14 interposed therebetween.
したがって回転軸11は、摩擦クラッチ140作用によ
って取付部に懸る負荷の度合に応じて緩速もしくは停止
を含んだ回転が伝達されるようになっている。Therefore, rotation of the rotating shaft 11 is transmitted at a slow speed or at a stop depending on the degree of load applied to the mounting portion by the action of the friction clutch 140.
ナツト受台装置2は取付部13の先端に対応する位置に
固定状態で設けられるものであって、第2図に示すよう
にナラ)bを起立塔載するに適したV形の受面を有する
受台21と、この受台21を上下に位置調節しうる例え
ばねじ式のジヤツキ22とによって形成され、手動操作
によって受台21の高さを調節可能になされている。The nut pedestal device 2 is fixedly provided at a position corresponding to the tip of the mounting portion 13, and has a V-shaped receiving surface suitable for placing the oak on the upright tower as shown in Fig. 2. The height of the pedestal 21 can be adjusted by manual operation.The height of the pedestal 21 can be adjusted by manual operation.
ナツト固定装置3は、ナツト受台装置20両側に組合っ
て起設される左右1組の装置であって、所定の長さを有
する支柱31の上端に固定用部材32を固定装着しであ
る。The nut fixing device 3 is a pair of left and right devices installed on both sides of the nut pedestal device 20, and has a fixing member 32 fixedly attached to the upper end of a support 31 having a predetermined length. .
固定用部材32は第4図および第5図に示すようにピン
33を突出させていて、予めナラ)bの周側面に設けで
あるピン穴b′に嵌合させることができるようにしであ
るが、ピン33は固定用部材32に固定的に突設される
ものではなく、該部材32の側面に穿設した長孔34に
沿って水平方行に摺動できるようになっている。The fixing member 32 has a protruding pin 33 as shown in FIGS. 4 and 5, and is designed in advance so that it can be fitted into a pin hole b' provided on the circumferential side of the oak. However, the pin 33 is not fixedly protruded from the fixing member 32, but is capable of sliding horizontally along a long hole 34 bored in the side surface of the member 32.
また固定用部材32と支柱31との係合面は鋸刃状断面
のような多条の溝が全面均一に形成してあり、したがっ
てボルト35によって取付けられた時の状態は、前記溝
面の嵌合によって正確に位置決めされて移動を生ずるこ
とがないと共に、ボルト35を僅かに緩めることによっ
てピン突出方向の位置を前後に調整できるようになって
いる。Further, the engagement surface between the fixing member 32 and the support column 31 has multiple grooves uniformly formed on the entire surface, such as a sawtooth cross section. The fitting allows accurate positioning and no movement, and by slightly loosening the bolt 35, the position in the protruding direction of the pin can be adjusted back and forth.
このためボルト穴36は長孔に形成しである。For this reason, the bolt hole 36 is formed into a long hole.
本装置を用いてナツト締付けを行なう場合は、保持装置
1の取付部13ヘスリーブaを嵌合装着し、ロールCお
よび押えリングdなどの所定の取付物を嵌込んだのちに
端部ヘナツ)bを螺挿して締付ける。When tightening a nut using this device, fit and attach the sleeve a to the mounting portion 13 of the holding device 1, fit the roll C and predetermined attachments such as the presser ring d, and then tighten the end nut (b). Insert the screw and tighten.
先ずナツ)bを受台21上に起立姿勢で塔載して上下方
向をジヤツキ22で調整し、ナツト固定装置3のピン3
3を、ナツトのピン穴b′に嵌入させる。First, place the nut) b on the pedestal 21 in an upright position, adjust the vertical direction with the jack 22, and then tighten the pin 3 of the nut fixing device 3.
3 into the pin hole b' of the nut.
ナツト固定装置3は、ナツ)bの左右に配置されたもの
が全く同一構造の対称配置であるので、ナツトの両側の
ピン穴b′に対して同一に嵌入し、回転方向の運動を拘
束しておく。Since the nut fixing devices 3 are arranged symmetrically with the same structure on the left and right sides of the nut (b), they fit into the pin holes b' on both sides of the nut in the same way and restrain movement in the rotational direction. I'll keep it.
この時、ナツ)bは既にスリーブaの螺合端に密接して
配置されている。At this time, the nut (b) is already placed in close contact with the threaded end of the sleeve (a).
こSで保持装置1のモータ15を駆動して回転軸11を
回転し、取付部13に装着しであるスリーブaに回転を
与える。This S drives the motor 15 of the holding device 1 to rotate the rotating shaft 11, thereby imparting rotation to the sleeve a attached to the mounting portion 13.
これによってスリーブ端に密接されているナツ)bは静
止状態のま3−J順次スリーブaの螺設部に嵌合されて
締付方向に移動し始める。As a result, the nut (b), which is in close contact with the end of the sleeve, remains stationary until it is sequentially fitted into the threaded portion of the sleeve (a) and begins to move in the tightening direction.
ナツトbの水平移動に伴なってナツト固定装置のピン3
3も僅かずつ長孔34に沿って水平方向に移動し、やが
て締付けが完了する。As the nut b moves horizontally, the pin 3 of the nut fixing device
3 also moves horizontally little by little along the elongated hole 34, and eventually the tightening is completed.
この締付過程においてナツトの螺合状態が適正でない場
合や締付けが完了して回転物体に過度の荷重負担が加わ
る場合には、保持装置における摩擦クラッチ14が適切
に断たれ、モータ15による回転力を回転軸11に伝達
させない。During this tightening process, if the threaded state of the nut is not appropriate or if excessive load is applied to the rotating object after tightening is completed, the friction clutch 14 in the holding device is appropriately disengaged, and the rotational force from the motor 15 is is not transmitted to the rotating shaft 11.
なおナツ)bのピン穴を軸方向に長くすればピンを移動
可能にしなくてもよい。Note that if the pin hole in b) is made longer in the axial direction, the pin does not need to be movable.
本考案の装置の開発によって大型ナツトの締付作業は極
めて容易となり、従来30分を要していた作業を10分
程度に短縮させることが可能となった。With the development of the device of the present invention, the work of tightening large nuts has become extremely easy, and the work that previously took 30 minutes can now be shortened to about 10 minutes.
したがって作業の能率は大幅に向上すると共に、作業者
は重筋作業から開放され、安全性も向上した。Therefore, work efficiency has been greatly improved, workers have been relieved of heavy muscle work, and safety has also improved.
