Description
【０００１】[0001]
本考案は、溶接鋼管の溶接部近傍の寸法を測定する器具に関する。 The present invention relates to an instrument for measuring a dimension of a welded steel pipe in the vicinity of a welded portion.
【０００２】[0002]
溶接鋼管における溶接部の種々の寸法測定値は、鋼管の品質に大きな影響を与 える為、その測定は、厳密に行われている。 測定項目は、図２に示すように、鋼管外周の曲率からの板の盛り上がり高さを 表したピーキング値（ａ）、溶接ビードの鋼管母材からの盛り上がり高さ（ｂ） 、溶接ビード左右の母材高さの差であるオフセット値（ｃ）、溶接ビード横のピ ット深さ（ｄ）の４項目である。 Since various dimensional measurement values of the welded portion in the welded steel pipe have a great influence on the quality of the steel pipe, the measurement is strictly performed. As shown in Fig. 2, the measurement items are the peaking value (a), which represents the rising height of the plate from the curvature of the steel pipe outer circumference, the rising height of the weld bead from the steel pipe base material (b), and the left and right of the weld bead. The four items are the offset value (c), which is the difference in base metal height, and the pit depth (d) beside the welding bead.
【０００３】 そしてその測定方法は、図３に示してある。 ピーキング測定（イ）は、門型架台にアナログダイヤルゲージを利用したピー キング測定専用器にて、まずフラットな面において０点調整をし、次に当測定器 を鋼管のビード横にセットし、実測値を読み取る。その読み取り値からそれぞれ の鋼管の外円周の曲率によって定まる定数（Ｎ値）を差引きし、ピーキング値を 求める。The measuring method is shown in FIG. The peaking measurement (a) is a peaking measurement dedicated device that uses an analog dial gauge on a portal frame, first adjusts the zero point on a flat surface, then sets the measurement device next to the bead of the steel pipe, Read the measured value. The peaking value is obtained by subtracting a constant (N value) determined by the curvature of the outer circumference of each steel pipe from the read value.
【０００４】 ビード高さ測定（ロ）は、ビード高さ測定専用測定器により、まず、ビード近 傍の鋼管の外円周の曲率を実測し、読み取る。次に、専用測定器をビード上にセ ットし、その高さから外円周の曲率の実測値を差引きビード高さを求める。In the bead height measurement (b), a bead height measuring device is used to measure and read the curvature of the outer circumference of the steel pipe near the bead. Next, the dedicated measuring device is set on the bead, and the measured value of the curvature of the outer circumference is subtracted from the height to obtain the bead height.
【０００５】 オフセット測定（ハ）は、門型架台にアナログダイヤルゲージを２個並列にセ ットしたオフセット専用測定器にて、２個のダイヤルゲージをまず０設定し、ビ ードの左右にそれぞれダイヤルゲージ先端をセットし、各目盛りを読み取る。そ の両者の差を計算し、オフセット値を求める。Offset measurement (c) is an offset measuring instrument in which two analog dial gauges are set in parallel on a gantry base, and the two dial gauges are first set to 0, and then the left and right sides of the bead are set. Set the tip of each dial gauge and read each scale. The difference between the two is calculated to obtain the offset value.
【０００６】 ピット深さ測定（ニ）は、やはり、アナログ式ダイヤルゲージをセットしたピ ット専用測定器によって、まず０点調整し、次いでピットにセットし、その実測 値を読み取る。 以上の方法で各測定値が測定されていた。In the pit depth measurement (d), the zero point adjustment is first performed by the pit-dedicated measuring instrument in which the analog dial gauge is set, and then the pit depth is set in the pit, and the measured value is read. Each measured value was measured by the above method.
【０００７】[0007]
前述のように、従来法では、各測定項目に対し、それ専用の測定器を使用して いたため４種類もの測定器を測定の度に取り替える必要があり、作業が煩雑とな っていた。また、各測定器の管理も大変であった。 更に、その測定方法は、測定精度も悪く、また、測定値を求める際に計算が必 要であり、計算間違えを招く可能性もあり、作業も煩雑であった。 As described above, in the conventional method, a measuring instrument dedicated to each measurement item was used, and therefore four types of measuring instruments had to be replaced each time measurement was performed, which made the work complicated. Also, the management of each measuring device was difficult. Furthermore, the measurement method has poor measurement accuracy, requires calculation when obtaining the measured value, may cause calculation error, and is complicated in work.
【０００８】 本考案の目的は、上記した従来の測定作業により生じる不都合を解消し、溶接 鋼管の溶接部の寸法測定が従来よりも短時間でしかも精度良く、更に、熟練工で なくとも簡単に測定できるようにした寸法測定器を提供することにある。The object of the present invention is to eliminate the inconvenience caused by the above-mentioned conventional measurement work, to measure the dimension of the welded portion of the welded steel pipe in a shorter time and with higher accuracy than before, and to perform the measurement easily even without a skilled worker. An object of the present invention is to provide a dimension measuring device that can be used.

以下、実施例によって、本考案を詳細に説明する。図１は、本考案による鋼管 の溶接部測定装置の一実施例である。 まず、鋼管の溶接ビード部をまたぐような姿勢で門型架台があり、その足部１ は先端が鋼管と線接触するように鋭角となっており、この部分は、摩耗が激しい ので、焼き入れ等の耐摩耗処理を施すことが好ましい。また、門型架台水平部２ は、その上をダイヤルゲージ４がゲージスライド台３を介してスライドするので その平坦度を高めるため精密加工を施している。ゲージスライド台３は、門型架 台水平部２をまたぐ様に設けられ、該ゲージスライド台３には、ダイヤルゲージ ４が固定され、門型架台水平部２上をダイヤルゲージ４がスライドする。ダイヤ ルゲージ４は、デジタル式であり、０点設定及び読み取りがワンタッチで出来る タイプである。そして、そのゲージスライド台３にダイヤルゲージ位置指示針６ が設置してあり、その針先にゲージ４の水平方向の位置を表示するダイヤルゲー ジ位置表示目盛７を設けている。この目盛７は、ゲージが門型架台水平部の中央 部にある時を０とし、その左右にゲージが移動すると、その移動距離が一目で読 み取れる様に目盛られている。 Hereinafter, the present invention will be described in detail with reference to examples. FIG. 1 shows an embodiment of a welded portion measuring device for a steel pipe according to the present invention. First of all, there is a gate-type mount in a position that straddles the weld bead of the steel pipe, and the foot 1 has an acute angle so that the tip makes line contact with the steel pipe, and since this part is heavily worn, it is hardened. It is preferable to perform abrasion resistance treatment such as. Further, since the dial gauge 4 slides on the gate-type mount horizontal portion 2 via the gauge slide base 3, precision processing is performed to increase the flatness thereof. The gauge slide base 3 is provided so as to straddle the horizontal portion 2 of the portal frame, and the dial gauge 4 is fixed to the gauge slide base 3, and the dial gauge 4 slides on the horizontal portion 2 of the portal platform. The dial gauge 4 is a digital type that can be set and read with one touch. A dial gauge position indicating needle 6 is installed on the gauge slide base 3, and a dial gauge position display scale 7 for displaying the horizontal position of the gauge 4 is provided at the tip of the needle. The scale 7 is set so that when the gauge is at the center of the horizontal part of the gate-type mount, it is 0, and when the gauge moves to the left and right, the movement distance can be read at a glance.
【００１１】 次に、本考案による鋼管の溶接部寸法測定器を使用した場合の測定手順を説明 する。 まず、ピーキング測定時は、Ｎ値の厚みのブロックゲージを予め用意しておき 、その鋼管の外円周にあったブロックゲージを本考案の測定器の下に置き、ダイ ヤルゲージ先端部５を当て、その状態で、ダイヤルゲージの０点設定ボタンを押 し、０点設定を行う。次に鋼管の溶接ビード横にゲージ５をセットし、その時の デジタル値を読む。それが、ピーキング測定値である。Next, a measuring procedure when the weld pipe dimension measuring device according to the present invention is used will be described. First, at the time of peaking measurement, prepare a block gauge with a thickness of N in advance, place the block gauge that was on the outer circumference of the steel pipe under the measuring instrument of the present invention, and apply the dial gauge tip 5 to it. In that state, press the 0 point setting button on the dial gauge to set 0 point. Next, set the gauge 5 beside the weld bead of the steel pipe and read the digital value at that time. That is the peaking measurement.
【００１２】 ビード高さ測定時は、本測定装置のゲージ先端５をビード横にセットし、その 状態で、０点設定を行う。次に架台はそのままで、ゲージスライド台３によりゲ ージ４をスライドし、ビード上にセットし、その時のデジタル値を読む。それが 、ビード高さ測定値である。At the time of measuring the bead height, the gauge tip 5 of the measuring device is set beside the bead, and 0 point is set in that state. Next, with the gantry as it is, slide the gauge 4 with the gauge slide 3 and set it on the bead, and read the digital value at that time. That is the measured bead height.
【００１３】 オフセット測定時は、ゲージ先端部５をビードの一端にセットし、０点設定す る。次に、もう一方のビード端にゲージ先端５をスライドし、その時のデジタル 値を読む。それが、オフセット測定値である。At the time of offset measurement, the gauge tip portion 5 is set at one end of the bead and 0 point is set. Next, slide the gauge tip 5 to the other bead end and read the digital value at that time. That is the offset measurement.
【００１４】 ピット測定時は、ピット横にゲージ先端部をセットし、０点設定する。次に、 ゲージ先端部５をピット内部にセットし、その時のデジタル値を読む。それが、 ピット測定値である。At the time of pit measurement, the tip of the gauge is set beside the pit to set 0 point. Next, set the gauge tip 5 inside the pit and read the digital value at that time. That is the pit measurement.
【００１５】 図４は、横軸に各４種の測定態様を、縦軸に測定時間をとり、本考案に係る測 定器と従来の個々の測定器とを対比したものである。いずれの測定においても本 考案測定器による測定時間の方が短かい（ほぼ２分の１）ことが確認された。In FIG. 4, the horizontal axis represents each of four types of measurement modes and the vertical axis represents the measurement time, and the measuring instrument according to the present invention is compared with the conventional individual measuring instruments. It was confirmed that the measurement time by the measuring device of the present invention was shorter (almost one half) in any measurement.
【００１６】[0016]
以上の様に、溶接鋼管の溶接部の各種寸法測定に際し、本考案による測定器を 使用する事により従来法では、各測定項目毎にそれ専用の測定器を使用していた ため４種類もの測定器を測定の度に取り替える必要があり、作業が煩雑であり、 且つ、測定器の管理も大変であったものが、本考案により４種類の測定に対して 、１つの測定器で良く、作業あるいは機器管理も簡単になり、且つ、個々の測定 方法も簡単になり計算もなく誤差が少なくなるうえに、各４種の測定時間共、従 来例のおよそ半分に短縮された。 As described above, when measuring the various dimensions of the welded portion of the welded steel pipe, by using the measuring device according to the present invention, the conventional method used a dedicated measuring device for each measurement item, so four types of measurement were performed.
