Description

この発明は、例えばエスカレータ用のＬ型トラス鋼材を溶接組立する時に用いられる位置決めクランプ装置に関するものである。   The present invention relates to a positioning clamp device used when, for example, an L-shaped truss steel material for escalators is welded and assembled.

従来のエスカレータのトラス構造には、図３に示すようにＬ型断面をしたＬ型鋼が用いられ、更に複数本のＬ型鋼が組合されて溶接されている。この溶接の際、Ｌ型鋼は予め、専用の溶接治具に固定されたＬ型鋼の水平方向当て面及び垂直方向当て面上にセットされ、更に位置ずれ防止のためリンク機構を用いたクランプ機構を使用し、Ｌ型鋼の水平方向Ｈ、垂直方向Ｖをクランプしている。
このようにＬ型鋼の水平方向Ｈ及び垂直方向Ｖをクランプする際は、一軸方向に対応したクランプ機構を２個用い、水平方向Ｈと垂直方向Ｖをクランプする方法が一般的である。
特許文献１に記載された従来のクランプ機構は、リンク機構を用い、ワーク寸法の変化に応じて一定のクランプ力を維持するために調整機能が設けられている。又、特許文献２に記載された従来のクランプ機構は、リンク機構を用い、ワークの押え部にばね部材が設けられており、ワークの板厚寸法変化及び板厚方向の位置ずれに対して、ばね部材の圧縮量を調整する事で一定のクランプ力を発揮する機構となっている。
何れのクランプ機構も、クランプ機構のクランプ力がワークに対して一軸方向のみに負荷される構造である。 As shown in FIG. 3, an L-shaped steel having an L-shaped cross section is used for a conventional escalator truss structure, and a plurality of L-shaped steels are combined and welded. At the time of this welding, the L-shaped steel is set in advance on the horizontal and vertical abutting surfaces of the L-shaped steel fixed to a dedicated welding jig, and a clamp mechanism using a link mechanism is used to prevent displacement. Used to clamp the horizontal direction H and vertical direction V of L-shaped steel.
In this way, when clamping the horizontal direction H and the vertical direction V of the L-shaped steel, a method of clamping the horizontal direction H and the vertical direction V by using two clamping mechanisms corresponding to the uniaxial direction is general.
The conventional clamping mechanism described in Patent Document 1 uses a link mechanism and is provided with an adjustment function in order to maintain a constant clamping force in accordance with changes in workpiece dimensions. In addition, the conventional clamping mechanism described in Patent Document 2 uses a link mechanism, and a spring member is provided at the work pressing part. With respect to the change in the plate thickness dimension of the workpiece and the displacement in the plate thickness direction, By adjusting the amount of compression of the spring member, the mechanism exerts a constant clamping force.
Each of the clamp mechanisms has a structure in which the clamping force of the clamp mechanism is loaded only in one axial direction with respect to the workpiece.

上記のような一般的なクランプ機構を採り入れたトラス鋼材用位置決めクランプ装置を使って、例えばエスカレータ用のＬ型トラス鋼材を溶接組立する場合には、Ｌ型鋼の水平方向Ｈ及び垂直方向Ｖをクランプするために２個のクランプ機構が必要となり、溶接治具に掛かる部品点数が多くなる。又部品点数の増加に伴い作業工数が増加するなどの課題があった。   For example, when an L-shaped truss steel material for escalators is welded and assembled using a positioning clamp device for a truss steel material incorporating a general clamping mechanism as described above, the horizontal direction H and the vertical direction V of the L-shaped steel are clamped. Therefore, two clamping mechanisms are required, and the number of parts applied to the welding jig increases. There are also problems such as an increase in the number of work steps as the number of parts increases.

この発明に係わるトラス鋼材用位置決めクランプ装置は、水平床面と垂直壁面を有するＬ型溶接治具にＬ型鋼を押圧するＬ型鋼押え部、及びリンク部を介し上記Ｌ型鋼押え部を押圧操作する操作レバー部を備えたトラス鋼材用位置決めクランプ装置において、上記Ｌ型鋼押え部に、上記Ｌ型鋼を水平方向に押圧する水平押え部と垂直方向に押圧する垂直押え部を一体形成し、この両押え部による２軸方向の押圧で上記Ｌ型鋼を上記Ｌ型溶接治具の両面に当接させ、上記Ｌ型鋼の位置決めを行うものである。   The truss steel positioning clamp device according to the present invention presses the L-shaped steel presser via an L-type steel presser that presses the L-type steel against an L-type welding jig having a horizontal floor surface and a vertical wall surface, and a link part. In the truss steel positioning clamp device having an operation lever portion, a horizontal press portion for pressing the L-shaped steel in a horizontal direction and a vertical press portion for pressing in the vertical direction are integrally formed on the L-type steel press portion. The L-shaped steel is brought into contact with both surfaces of the L-type welding jig by pressing in two axial directions by the portion, and the L-shaped steel is positioned.

この発明のトラス鋼材用位置決めクランプ装置によれば、Ｌ型鋼がクランプされた際、Ｌ型鋼押え部のＬ型鋼水平方向押え面とＬ型鋼垂直部が当接し、又Ｌ型鋼垂直方向押え部とＬ型鋼水平部が当接する事でＬ型鋼の水平方向Ｈ、垂直方向Ｖの両方向にクランプ力が負荷され、一つのクランプ機構で水平方向Ｈと垂直方向Ｖの２軸方向同時にクランプする事が出来且つ所定のクランプ力を発揮する事が出来る。又、溶接治具を構成する部品点数及び作業工数が軽減出来る利点もある。   According to the truss steel positioning clamp device of the present invention, when the L-shaped steel is clamped, the L-shaped steel horizontal pressing surface of the L-shaped steel pressing portion and the L-shaped steel vertical pressing portion abut, and the L-shaped steel vertical pressing portion and L Clamping force is applied in both the horizontal direction H and vertical direction V of the L-shaped steel due to the contact of the horizontal part of the steel shape, and it is possible to clamp the two axial directions of the horizontal direction H and the vertical direction V simultaneously with a single clamping mechanism. A predetermined clamping force can be exhibited. In addition, there is an advantage that the number of parts and work man-hours constituting the welding jig can be reduced.

以下、図１〜図５に基づきこの発明の実施の形態１であるエスカレータ用トラス鋼材の位置決めクランプ装置の構成と動作を説明する。
位置決めクランプ装置は、溶接組立治具ベース面３に並設されたクランプ機構６とＬ型溶接治具４５とにより構成され、Ｌ型溶接治具４５上にＬ型鋼２を載置する。
クランプ機構６は、Ｌ型鋼２をＬ型溶接治具４５に押圧するＬ型鋼押え部６３と、リンク部６２を介しＬ型鋼押え部６３を押圧操作する操作レバー部６１により構成され、各々の回転運動を妨げないように、各軸で連結されている。
操作レバー部６１は、操作レバー部回転中心６４を中心に回転運動し、それに連動しＬ型鋼押え部６３が稼動する。
Ｌ型溶接治具４５は、水平床面（Ｌ型鋼垂直方向当て面５）と垂直壁面（Ｌ型鋼水平方向当て面４）を備えている。
Ｌ型鋼押え部６３は、リンク部６２の先端に設けられ、Ｌ型トラス鋼材２の垂直部２２を水平方向に押圧する水平方向押え面６３１と、Ｌ型トラス鋼材２の水平部２１を垂直方向に押圧する垂直方向押え押え面６３２がＬ型に一体形成されている。
この両押え面による２軸方向の同時押圧で、次に述べるようにＬ型鋼２をＬ型溶接治具の水平床面（Ｌ型鋼垂直方向当て面５）と垂直壁面（Ｌ型鋼水平方向当て面４）に当接させ、Ｌ型鋼２の位置決めを行う。 Hereinafter, the configuration and operation of the positioning clamp device for truss steel material for escalator, which is Embodiment 1 of the present invention, will be described with reference to FIGS.
The positioning clamp device is configured by a clamp mechanism 6 and an L-type welding jig 45 arranged side by side on the welding assembly jig base surface 3, and the L-type steel 2 is placed on the L-type welding jig 45.
The clamp mechanism 6 includes an L-shaped steel pressing portion 63 that presses the L-shaped steel 2 against the L-type welding jig 45, and an operation lever portion 61 that presses the L-shaped steel pressing portion 63 via the link portion 62. It is connected with each axis so as not to disturb the movement.
The operation lever portion 61 rotates around the operation lever portion rotation center 64, and the L-shaped steel presser portion 63 operates in conjunction with the operation lever portion 61.
The L-type welding jig 45 includes a horizontal floor surface (L-shaped steel vertical contact surface 5) and a vertical wall surface (L-shaped steel horizontal contact surface 4).
The L-shaped steel retainer 63 is provided at the tip of the link portion 62, and the horizontal retainer surface 631 that presses the vertical portion 22 of the L-shaped truss steel 2 in the horizontal direction and the horizontal portion 21 of the L-shaped truss steel 2 in the vertical direction. A vertical presser pressing surface 632 that presses in the L-shape is integrally formed.
By simultaneous pressing in the two axial directions by both pressing surfaces, the L-shaped steel 2 is turned into a horizontal floor surface (L-shaped steel vertical contact surface 5) and a vertical wall surface (L-shaped steel horizontal contact surface) as described below. 4), the L-shaped steel 2 is positioned.

次にクランプ機構６によるＬ型鋼２のクランプ操作について説明する。
Ｌ型鋼２は、Ｌ型溶接治具４５の水平床面（Ｌ型鋼垂直方向当面５）上に置かれ、このＬ型鋼２の位置決めは、操作レバー部６１を、図１の状態から図２の状態まで回動操作することにより行われる。
操作レバー部６１を回動操作すると、Ｌ型鋼押え部６３が図４に示す矢印方向（Ｌ型鋼押え部の回転方向７）に回転運動を行う。
このとき、Ｌ型鋼２が、垂直壁面（Ｌ型鋼水平方向当て面４）とＬ型鋼垂直部２２との間に隙間がない正常な状態で置かれている場合には、図５に示すように、Ｌ型鋼水平方向押え面６３１とＬ型鋼垂直方向押え面６３２が、Ｌ型鋼水平部２１とＬ型鋼垂直部２２に均等に面接触し、必要クランプ力であるＦＨ、ＦＶの力が発揮される。
すなわち、Ｌ型鋼２がクランプされた際は、図２、図５に示すように、Ｌ型鋼押え部６３のＬ型鋼水平方向押え面６３１とＬ型鋼垂直部２２が接触（当接）し、又Ｌ型鋼垂直方向押え部６３２とＬ型鋼水平部２１が接触（当接）する事でＬ型鋼２の水平方向Ｈ、垂直方向Ｖにクランプ力が負荷され、一つのクランプ機構で水平方向Ｈと垂直方向Ｖの２軸方向を同時にクランプする事が出来且つ所定のクランプ力を発揮する事が出来る。 Next, the clamping operation of the L-shaped steel 2 by the clamping mechanism 6 will be described.
The L-shaped steel 2 is placed on the horizontal floor surface (L-shaped steel vertical contact surface 5) of the L-shaped welding jig 45, and the positioning of the L-shaped steel 2 is performed by moving the operation lever portion 61 from the state of FIG. This is done by rotating the state.
When the operation lever portion 61 is turned, the L-shaped steel presser portion 63 rotates in the arrow direction shown in FIG. 4 (the rotation direction 7 of the L-type steel presser portion).
At this time, when the L-shaped steel 2 is placed in a normal state with no gap between the vertical wall surface (L-shaped steel horizontal contact surface 4) and the L-shaped steel vertical portion 22, as shown in FIG. The L-shaped steel horizontal pressing surface 631 and the L-shaped steel vertical pressing surface 632 are in surface contact with the L-shaped steel horizontal portion 21 and the L-shaped steel vertical portion 22 evenly, and the necessary clamping forces F H and F V are exerted. Is done.
That is, when the L-shaped steel 2 is clamped, as shown in FIGS. 2 and 5, the L-shaped steel horizontal pressing surface 631 of the L-shaped steel pressing portion 63 and the L-shaped steel vertical portion 22 come into contact (contact), or When the L-shaped steel vertical holding part 632 and the L-shaped steel horizontal part 21 come into contact (abut), a clamping force is applied in the horizontal direction H and the vertical direction V of the L-shaped steel 2, and the horizontal direction H is vertical with one clamping mechanism. The two axial directions V can be clamped simultaneously and a predetermined clamping force can be exhibited.

実施の形態２．
この発明の実施の形態２であるエスカレータ用トラス鋼材の位置決めクランプ装置は、
実施の形態１のクランプ装置に、Ｌ型鋼２の位置ずれ修正機構を付加したものである。
まず、Ｌ型鋼２の位置ずれによる現象について、実施の形態１と同一形状のＬ型鋼押え部６３が図示された図１２〜図１５に基づき説明する。
図１２〜図１５において、Ｌ型鋼２が、Ｌ型鋼垂直部２２とＬ型鋼水平方向当て面４間に隙間８がある状態でセットされた場合、すなわちＬ型鋼２が位置ずれして置かれた場合、操作レバー部６１を回動操作すると、Ｌ型鋼押え部６３とＬ型鋼２とが、図１２に示すように、まず点Ａから接触する。
その後、図１３に示すように、Ｌ型鋼２はＬ型鋼押え部６３から点Ａに受ける力によって点Ｂを中心に回転し、その際、Ｌ型鋼垂直部２２はＬ型鋼水平方向当て面４と点Ｃで接触する。
更に、Ｌ型鋼押え部６３が回転した場合、Ｌ型鋼２は、点Ｄを中心にＬ型鋼水平方向当て面４及びＬ型鋼垂直方向当て面５上を反時計方向に滑り、図１４に示すようにＬ型鋼水平方向押え面６３１とＬ型鋼垂直方向押え面６３２に倣う状態となる。
更に、Ｌ型鋼押え部６３を回転させようとした場合は、点ＢにはＬ型鋼水平部２１に対して直角方向に作用する力ＦＢが増加し、又点ＣにはＬ型鋼垂直部２２に対して直角方向に作用する力ＦＣが増加する。よってクランプ力の増加に伴い点Ｂ、点Ｃにおける摩擦力も増大する。これらの摩擦力はＬ型鋼２がＬ型鋼水平面当て面部４及びＬ型鋼垂直方向当て面部５に面接触しようとする運動の抵抗となるため、Ｌ型鋼押え部６３を稼動することが出来なくなり、最終的には図１５に示す状態でクランプされてしまう。
この場合の水平方向Ｈ及び垂直方向Ｖのクランプ力は、図１５に示すＦＨ１、ＦＶ１となり、所定のクランプ力ＦＨ、ＦＶよりも弱い力となる。この状態で溶接された場合はＬ型鋼２の位置ずれによりトラスが変形する。又溶接の熱歪みによる力にＬ型鋼２のクランプ力が打ち負けてトラスが変形する。
このように位置ずれした状態でＬ型鋼２がセットされた場合、すなわちＬ型鋼２の置き方によって、水平方向Ｈ及び垂直方向Ｖのクランプ力が変化する、もしくはＬ型鋼２が位置ずれした状態でクランプされるため、溶接後にクランプ力を開放した際、溶接後のトラスが変形する問題が生じ、溶接後の工程で変形の修正を行う作業が発生する恐れがある。 Embodiment 2. FIG.
The positioning clamp device for the truss steel material for escalators, which is Embodiment 2 of the present invention,
In this embodiment, a position deviation correction mechanism for the L-shaped steel 2 is added to the clamping device of the first embodiment.
First, the phenomenon caused by the displacement of the L-shaped steel 2 will be described with reference to FIGS. 12 to 15 in which the L-shaped steel pressing portion 63 having the same shape as that of the first embodiment is illustrated.
12 to 15, when the L-shaped steel 2 is set in a state where there is a gap 8 between the L-shaped steel vertical portion 22 and the L-shaped steel horizontal contact surface 4, that is, the L-shaped steel 2 is placed out of position. In this case, when the operation lever portion 61 is rotated, the L-shaped steel pressing portion 63 and the L-shaped steel 2 first come into contact from the point A as shown in FIG.
Thereafter, as shown in FIG. 13, the L-shaped steel 2 is rotated around the point B by the force received at the point A from the L-shaped steel pressing portion 63, and at this time, the L-shaped steel vertical portion 22 is aligned with the L-shaped steel horizontal contact surface 4. Contact at point C.
Further, when the L-shaped steel presser 63 rotates, the L-shaped steel 2 slides counterclockwise on the L-shaped steel horizontal facing surface 4 and the L-shaped steel vertical facing surface 5 around the point D, as shown in FIG. Then, the L-shaped steel horizontal pressing surface 631 and the L-shaped steel vertical pressing surface 632 are imitated.
Furthermore, if it is attempted to rotate the L-shaped steel pressing portion 63, the point B increases the force F B acting in the direction perpendicular to the L-type steel horizontal section 21, the Mataten C L-section steel vertical portion 22 force F C increases acting in a direction perpendicular to. Therefore, as the clamping force increases, the frictional force at points B and C also increases. These frictional forces cause the movement of the L-shaped steel 2 to come into surface contact with the L-shaped steel horizontal surface contacting surface portion 4 and the L-shaped steel vertical surface contacting surface portion 5, so that the L-shaped steel pressing portion 63 cannot be operated. Specifically, it is clamped in the state shown in FIG.
The clamping forces in the horizontal direction H and the vertical direction V in this case are F H1 and F V1 shown in FIG. 15, which are weaker than the predetermined clamping forces F H and F V. When welding is performed in this state, the truss is deformed due to the displacement of the L-shaped steel 2. Also, the truss is deformed because the clamping force of the L-shaped steel 2 is defeated by the force caused by the thermal distortion of welding.
When the L-shaped steel 2 is set with the position shifted in this manner, that is, the clamping force in the horizontal direction H and the vertical direction V changes depending on how the L-shaped steel 2 is placed, or the L-shaped steel 2 is displaced. Since it is clamped, there is a problem that when the clamping force is released after welding, there is a problem that the truss after welding is deformed, and there is a possibility that an operation for correcting the deformation occurs in the process after welding.

次に、図６〜図１１に基づき、Ｌ型鋼２が位置ずれした状態で溶接治具上にセットされた場合でも、その位置ずれを修正し且つ所定のクランプ力を発揮する実施の形態２の位置決めクランプ装置を説明する。
図６と図７は、位置決めクランプ装置によるクランプ操作が行われる前の状態と、位置決めクランプ装置によるクランプ状態を示す全体側面図、図８〜図１０は、クランプ機構によるクランプ動作を説明する説明図である。 Next, based on FIGS. 6 to 11, even when the L-shaped steel 2 is set on the welding jig in a shifted state, the positional shift is corrected and a predetermined clamping force is exhibited. The positioning clamp device will be described.
6 and 7 are a side view illustrating a state before the clamping operation by the positioning clamp device and a clamping state by the positioning clamp device, and FIGS. 8 to 10 are explanatory diagrams for explaining a clamping operation by the clamping mechanism. It is.

図６〜図１１において、この実施の形態２である位置決めクランプ装置は、実施の形態１と同様にクランプ機構６とＬ型溶接治具４５とにより構成される。なお、実施の形態１のクランプ装置と同一又は相当部分については説明を省略する。
クランプ機構６は、Ｌ型鋼押え部６３、リンク部６２、及び操作レバー部６１で構成されており、各々の回転運動を妨げないように、各軸で連結されている。
Ｌ型鋼押え部６３は、リンク部６２の先端に設けられ、水平方向押え面６３１と、垂直方向押え押え面６３２がＬ型に一体形成されている。
Ｌ型鋼押え部６３のコーナー部には、位置ずれ修正機構が設けられる。この位置ずれ修正機構は、弾性部材（コイル状のばね部材６３３）で構成され、Ｌ型鋼押え部６３のコーナー部のＬ型鋼垂直部に対向する側に切削加工で開けた有底穴に挿入されている。
更に、弾性部材６３３の一方の端部は、Ｌ型鋼押え部６３に固定され、自由端部を形成する他方端部にはＬ型鋼２を弾性的に押圧する押圧部材（金属球体を半分割した形状の押付け部材６３４）が設けられている。更に又ばね部材６３３の伸縮又は撓み方向は、図７、図１０に示すようにＬ型鋼垂直方向当て面５に平行で且つＬ型鋼水平方向当て面４に直角方向である。
又、位置ずれ修正機構（６３３、６３４）の取付け位置（Ｌ型鋼押え部６３の垂直方向に対する取付け位置）は、Ｌ型鋼２の重心位置よりも低い位置に設定される。 6 to 11, the positioning clamp device according to the second embodiment includes a clamp mechanism 6 and an L-type welding jig 45 as in the first embodiment. In addition, description is abbreviate | omitted about the part which is the same as that of the clamp apparatus of Embodiment 1, or an equivalent part.
The clamp mechanism 6 includes an L-shaped steel pressing portion 63, a link portion 62, and an operation lever portion 61, which are coupled to each other so as not to hinder each rotational movement.
The L-shaped steel presser portion 63 is provided at the tip of the link portion 62, and a horizontal presser surface 631 and a vertical presser presser surface 632 are integrally formed in an L shape.
A misalignment correction mechanism is provided at the corner of the L-shaped steel presser 63. This misalignment correcting mechanism is formed of an elastic member (coiled spring member 633), and is inserted into a bottomed hole that is cut by machining on the side of the corner portion of the L-shaped steel retainer 63 that faces the L-shaped steel vertical portion. ing.
Furthermore, one end of the elastic member 633 is fixed to the L-shaped steel presser 63, and the other end forming the free end is a pressing member that elastically presses the L-shaped steel 2 (the metal sphere is divided in half). A shaped pressing member 634) is provided. Furthermore, the expansion / contraction or deflection direction of the spring member 633 is parallel to the L-shaped steel vertical contact surface 5 and perpendicular to the L-shaped steel horizontal contact surface 4 as shown in FIGS.
Further, the attachment position of the displacement correction mechanism (633, 634) (the attachment position of the L-shaped steel presser 63 in the vertical direction) is set to a position lower than the gravity center position of the L-shaped steel 2.

次にクランプ機構６によるＬ型鋼２のクランプ操作について説明する。
図６、図８に示すように、Ｌ型鋼２がＬ型鋼水平方向当て面４に対して隙間がある状態でセットされた場合、つまりＬ型鋼２の位置ずれ状態で、クランプ機構６の操作レバー６１を回動操作すると、図９に示すように押付け部材６３４とＬ型鋼垂直部２２が最初に接触する。このとき、弾性部材（６３３、６３４）の取付け位置が、Ｌ型鋼２の重心位置よりも低いため、弾性部材（６３３、６３４）は、Ｌ型鋼２の重心位置よりも低い位置でＬ型鋼２と接触する。この結果、Ｌ型鋼２は、回転したり傾いたりする事なく、Ｌ型鋼垂直方向当て面５上を水平移動し、隙間８なくＬ型鋼垂直部２２とＬ型鋼水平方向当て面４を面接触させる事が出来る。 Next, the clamping operation of the L-shaped steel 2 by the clamping mechanism 6 will be described.
As shown in FIGS. 6 and 8, when the L-shaped steel 2 is set with a gap with respect to the L-shaped steel horizontal contact surface 4, that is, when the L-shaped steel 2 is displaced, the operation lever of the clamp mechanism 6 is operated. When 61 is rotated, as shown in FIG. 9, the pressing member 634 and the L-shaped steel vertical portion 22 first come into contact with each other. At this time, since the mounting position of the elastic members (633, 634) is lower than the center of gravity position of the L-shaped steel 2, the elastic members (633, 634) are positioned at a position lower than the center of gravity of the L-shaped steel 2 and the L-shaped steel 2 Contact. As a result, the L-shaped steel 2 horizontally moves on the L-shaped steel vertical contact surface 5 without rotating or tilting, and the L-shaped steel vertical portion 22 and the L-shaped steel horizontal contacting surface 4 are brought into surface contact without any gap 8. I can do it.

上記のごとく、押付け部材６３４がＬ型鋼垂直部２２に対して最初に接触しＬ型鋼２の位置ずれを修正するので、Ｌ型鋼２が溶接治具上に位置ずれした状態でセットされた場合でも、弾性部材（６３３、６３４）によって、クランプ前に予め隙間８を詰め、所定の位置に所定のクランプ力を発揮する事が可能であり、溶接後に発生する変形を低減する事が出来る。
又、Ｌ型鋼垂直部２２とＬ型鋼水平方向当て面４が面接触した際、弾性部材（６３３）の圧縮量又は撓み量も大きくなるので、それに伴い弾性部材先端の押付け部材６３４は、Ｌ型鋼水平方向押え面よりも突出する事がなくクランプに支障をきたす事はない。
更に、ばね部材６３３と押付け部材６３４の取付け位置はＬ型鋼２の重心位置よりも低く設定されているため、Ｌ型鋼２は回転したり傾いたりする事なく、Ｌ型鋼垂直方向当て面５上を水平移動させ、Ｌ型鋼垂直部２２とＬ型鋼水平方向当て面４を面接触させる事が出来るので、Ｌ型鋼２をＬ型溶接治具の水平床面と垂直壁面に確実に密着させる事が出来る。
更に又、溶接前におけるＬ型鋼２の位置ずれ及び溶接後の変形を軽減する事が期待出来るので、溶接後に変形の修正作業を軽減する事が出来、生産性が向上する。
更に又、Ｌ型鋼２の水平方向Ｈにおけるクランプ力ＦＨ２は、従来の必要クランプ力とばね部材の反力の和となるため、従来よりもクランプ力が低下する事もない。 As described above, the pressing member 634 first comes into contact with the L-shaped steel vertical portion 22 to correct the displacement of the L-shaped steel 2, so that even when the L-shaped steel 2 is set in a state of being displaced on the welding jig. By the elastic members (633, 634), it is possible to close the gap 8 in advance before clamping and to exert a predetermined clamping force at a predetermined position, and it is possible to reduce deformation generated after welding.
Further, when the L-shaped steel vertical portion 22 and the L-shaped steel horizontal contact surface 4 are in surface contact, the amount of compression or deflection of the elastic member (633) also increases, and accordingly, the pressing member 634 at the tip of the elastic member is L-shaped steel. It does not protrude from the horizontal holding surface and does not hinder the clamp.
Furthermore, since the mounting position of the spring member 633 and the pressing member 634 is set lower than the position of the center of gravity of the L-shaped steel 2, the L-shaped steel 2 does not rotate or tilt, and the L-shaped steel vertical surface 5 is not rotated. Since the L-shaped steel vertical portion 22 and the L-shaped steel horizontal contact surface 4 can be brought into surface contact with each other, the L-shaped steel 2 can be reliably brought into close contact with the horizontal floor surface and the vertical wall surface of the L-type welding jig. .
Furthermore, since it can be expected that the displacement of the L-shaped steel 2 before welding and the deformation after welding can be reduced, the work for correcting the deformation after welding can be reduced, and the productivity is improved.
Furthermore, since the clamping force F H2 in the horizontal direction H of the L-shaped steel 2 is the sum of the conventional required clamping force and the reaction force of the spring member, the clamping force is not reduced as compared with the conventional case.
