Description

【０００１】
【発明の属する技術分野】
本発明は、溶接部バリ取り装置および溶接部バリ取り方法に関し、とくに、不等厚平板、形鋼などを巻き、端部を溶接した環状リム素材の溶接部のバリ取りに適用できる溶接部バリ取り装置および溶接部バリ取り方法に関する。
【０００２】
【従来の技術】
ホイールのリムには、従来、図１に示す平板形状素材１、および図２に示す形鋼形状素材２の、２種類の素材の何れかの素材が使用されている。さらに、特開平８−９１００５号公報に示す不等厚材料素材３（図３）などの素材の使用も知られている。
それらの素材からのリムの製造工程を図４に示す。これらの製造工程において、平板については、図４（イ）に示すように、巻き４、溶接５、トリミング６後、主にロール成形７によりリム形状を形成している。特開平８−９１００５号公報の不等厚材料については、図４（ロ）に示すように、トリミング工程を除き、平板からのリム成形と同じ工程を想定している。想定としたのは、特開平８−９１００５号の工程による製作が未実施であるためである。形鋼については、形鋼が最終形状に近い断面形状となっているため、図４（ハ）に示すように、巻き、溶接後、分割型を用いた主に径方向への拡大成形（サイジング）８となる。
また、リム溶接後のトリミング（バリ取り）については、平板素材では、図５（イ）、（ロ）に示すように、刃具９を環状素材の軸方向に動かして加工している（軸方向トリム、フラットトリミング）。また、形鋼では、凹凸があるため、図６（イ）、（ロ）に示すように、セクションと同じ形状がついた刃具１０を周方向に動かして加工している（周方向トリム、ロータリートリマー）。特開平８−９１００５号の不等厚素材については、形鋼の場合に準じるトリミングとなることが想定される。
上記技術には、以下の問題がある。
フラットトリミングは、平板素材用に対しては、仕上がり外観、生産性などの要求が、ほぼ満足されている。しかし、凹凸のある形鋼素材や、不等厚平板素材に対しては、フラットトリミングでは刃具が水平にしか動かないためリム凹部分のバリ除去ができない。
また、ロータリートリマーを用いた周方向トリムでは、図７に示すように、切除素材４０の取り残し４１が後工程（成形工程等）で押し込まれてカブリ４２が発生し、それを放置すると切欠き効果による亀裂発生や割れ発生の問題を生じるほか、外観不良の問題を生じ、それを除去しようとすると、形鋼同様、後加工に多大のコストを要する。

【発明が解決しようとする課題】
上記問題を解決するために、すなわち、溶接部伸長方向に凹凸をもつ形状を有するバリ除去対象材のバリ除去にも適用可能とするために、本出願人は、図８に示すように、倣いローラ１３を、バリ除去対象材１２の表面に押し付け、バリ除去対象材１２の溶接部伸長方向と平行方向に送るとともに、倣いローラ１３に連動してバリ取り切削刃１５を移動させ、該バリ取り切削刃１５にてバリ除去対象材の溶接部のバリを除去する装置、方法を開発中である。
その装置、方法において、倣いローラ１３とバリ取り切削刃１５の高さ位置は、一度調整されると位置関係は固定である。しかし、トリミングの前工程である突合せ溶接では巻き始終端部の突合せ角度にバラツキがあるので、トリミング工程においてバリの取り過ぎや取り残しが発生する。たとえば、図８において、巻き始終端部の突合せ角度差による溶接部高さの差Ａ、および巻き始終端部の突合せ角度差によるローラ走行部高さの差Ｂに、それぞれ差が発生すると、溶接バリの取り過ぎや取り残しが発生する。発生した場合には、再度人が倣いローラ１３とバリ取り切削刃１５の高さ位置関係を調整する必要があるが、調整しても、ワーク毎に巻き始終端部の突合せ角度のバラツキが異なるので、全ワークに対して満足できる調整はできない。
【０００５】
本発明の目的は、平板素材または不等厚素材または形鋼素材を巻き、巻き始終端部を溶接した環状素材の溶接部のバリを、倣いローラとバリ取り切削刃を連動させて除去する場合に、巻き始終端部の突合せ角度にバラツキがあっても、溶接バリの取り過ぎや取り残しを発生させることがない溶接部バリ取り装置および溶接部バリ取り方法を提供することにある。

【０００８】
【発明の実施の形態】
以下に、本発明の溶接部バリ取り装置および溶接部バリ取り方法を図９〜図１１を参照して説明する。
図９に示すように、本発明の溶接部バリ取り装置１１は、倣いローラ１３（倣いローラ１３をたとえば一対設け、該一対の倣いローラのうち一方のローラを１３Ａ、他方のローラを１３Ｂとする）と、倣いローラ１３をバリ除去対象材１２の表面に押し付けるローラ倣い機構１４と、バリ取り切削刃１５（バリ取り切削刃１５をたとえば一対設け、該一対のバリ取り切削刃１５のうち一方の切削刃を１５Ａ、他方の切削刃を１５Ｂとする）と、バリ取り切削刃１５をバリ除去対象材１２の表面に進退する方向に倣いローラ１３に連動させる連動機構１６と、倣いローラ１３およびバリ取り刃１５をバリ除去対象材１２に対してバリ除去対象材の溶接部伸長方向に相対的に移動させる移動部材１７とを、バリ除去対象材１２の端部突合せ角度を測定する測定装置３０と、測定装置３０の測定結果から倣いローラ１３に対するバリ取り切削刃１５の高さ位置を自動調整するバリ取り切削刃高さ位置調整機構５０と、備えている。
【０００９】
倣いローラ１３Ａ、１３Ｂは、互いに独立に、バリ除去対象材１２の両面に、面直方向（バリ除去対象材１２の表面に直交する方向）に、進退可能である。
ローラ倣い機構１４は、たとえば、移動部材１７に設けられた回動支点１８のまわりに回動可能に支持されたＬ字状アーム１９と、Ｌ字状アーム１９に連結されたシリンダ２０とを有する。Ｌ字状アーム１９のＬ字の一方の脚１９ａは、バリ除去対象材１２の溶接部１２ａの伸長方向と平行に延びており、その脚１９ａに倣いローラ１３とバリ取り切削刃１５が支持されている。Ｌ字状アーム１９のＬ字の他方の脚１９ｂと移動部材１７との間には、シリンダ２０が設けられ、シリンダ２０の一端が移動部材１７に回動可能に連結され、シリンダ２０のロッド２１の先端が脚１９ｂに回動可能に連結されている。シリンダ２０−ロッド２１の伸縮により、Ｌ字状アーム１９が支点１８のまわりに回動し、倣いローラ１３とバリ取り切削刃１５がバリ除去対象材１２に対して進退する。
図９の例では、シリンダ２０−ロッド２１で倣いローラ１３をバリ除去対象材１２に押し付けているが、シリンダ２０−ロッド２１に代えて、さらバネ、コイルバネ、ガスバネ等を用いてもよい。
【００１０】
連動機構１６は、倣いローラ１３を支持する脚１９ａにバリ取り切削刃１５を、倣いローラ１３のバリ除去対象材１２との接触点とバリ取り切削刃１５の刃先端とが倣いローラ１３送り方向にほぼ同位置となるように、支持する。倣いローラ１３がバリ除去対象材１２の表面の形状にならって移動する時、バリ取り切削刃１５は、連動機構１６、Ｌ字状アーム１９の脚１９ａを介して、倣いローラ１３の動きに連動してバリ除去対象材１２の表面の形状にならって移動する。
【００１１】
バリ除去対象材１２の始終端部突合せ角度を測定する測定装置３０は、たとえば、レーザ変位測定機（ただし、レーザ変位測定機に限るものではない）である。ただし、レーザ変位測定機に代えて、始終端部突合せ角度を、バリ除去対象材１２の表面のうち倣いローラ１３が接触する位置（この位置は倣いローラ１３からわかる）と溶接バリの立ち上がり近傍位置に接触して溶接部位置を測定する接触型測定機の測定値との差から求める装置または方法により求めてもよい。
【００１２】
測定装置３０がレーザ変位測定機（測定装置と同じであるため符号を３０とする）の場合、図１０、図１１に示すように、レーザ変位測定機３０は、レーザ光３１をバリ除去対象材１２の表面に照射するレーザ照射装置３２と、その（拡散）反射光３３を受光し各画素ごとの光量を検出するＰＳＤ受光素子３４（「ＰＳＤ」は、「光位置検出素子」のこと）と、を有し、三角測距方式でバリ除去対象材の光照射位置３５の基準位置３６からの変位ｄを求める測定機からなる。
レーザ照射装置３２はレーザ光３１（円柱状光で、ワーク表面ではスポット状の照射となる）を、円筒状バリ除去対象材の軸芯と直交する平面内において、円筒状のバリ除去対象材の周方向に、所定範囲（測定範囲）にわたって振る。ＰＳＤ受光素子３４の各画素はワークの軸芯を含む平面内にあり、画素をスキャンして光量の多い画素がどれかを求めることで、バリ除去対象材の光照射位置３５の基準位置３６からの変位ｄを求めることができる。この種のレーザ変位測定機には、市販のレーザ変位測定機を用いることができる。
【００１３】
バリ取り切削刃高さ位置調整機構５０は、測定装置３０で求めた端部突合せ角度とワーク板厚からバリ取り切削刃高さ位置調整分回転するサーボモータ５１と、バリ取り切削刃１５をバリ除去対象材１２の表面に進退する方向に倣いローラ１３に連動させる連動機構１６の一部を構成し、サーボモータ５１の回転を、バリ取り切削刃の高さ方向直線移動に変換してバリ取り切削刃１５の高さ位置を調整する回転／直線変換機構５２（たとえば、ボールネジ機構など）と、サーボモータ５１の回転を回転／直線変換機構５２に伝達する手段５３（たとえば、タイミングベルトなど）を有している。
【００１４】
バリ取り切削刃１５は、バリ除去対象材１２の溶接部１２ａ伸長方向に、互いに間隔をもたせて、２個（２セット）設けられている。２個のバリ取り切削刃１５のうち、バリ取り切削刃送り方向前方にあるバリ取り切削刃１５は荒切削用のバリ取り切削刃であり、２個のバリ取り切削刃１５のうち、バリ取り切削刃送り方向後方にあるバリ取り切削刃１５は仕上げ切削用のバリ取り切削刃である。荒切削用のバリ取り切削刃は設けなくてもよいが、荒切削用のバリ取り切削刃を設けてバリを切削した後、測定装置３０により測定しバリ取り切削刃高さ位置調整機構５０で仕上げ切削用のバリ取り切削刃の高さ位置を調整してバリを切削した方が、バリによる測定への影響が少なくなる分、高精度なバリ除去を行うことができる。
【００１５】
バリ除去対象材１２は、平板、形鋼、不等厚平板の何れかからなる素材を巻き加工し端部を突き合わせ溶接した環状のホイールリム素材であってもよい。その場合、溶接部１２ａは端部の突き合わせ溶接部である。そして、バリ取り切削刃１５は、溶接部１２ａに平行に、環状のホイールリム素材の軸方向に送られる。形鋼、不等厚平板の場合は、素材表面は凹凸しており、バリ取り切削刃１５は凹凸に倣いながら、ホイールリム素材の軸方向に送られる。
【００１６】
つぎに、上記バリ除去装置を用いて実施される本発明の溶接部バリ取り方法（上記バリ除去装置の作用でもある）を説明する。
本発明の溶接部バリ取り方法は、倣いローラ１３（倣いローラ１３が一対設けられる場合は、倣いローラ１３Ａ、１３Ｂ）を、バリ除去対象材１２の表面にそれぞれ押し付け、バリ除去対象材１２の溶接部１２ａ伸長方向と平行方向に送るとともに、倣いローラ１３に連動してバリ取り切削刃１５（バリ取り切削刃１５が一対設けられる場合は、バリ取り切削刃１５Ａ、１５Ｂ）を移動させ、バリ取り切削刃１５にてバリ除去対象材１２の溶接部１２ａのバリ１２ｂを除去する方法であって、測定装置３０によりバリ除去対象材１２の端部突合せ角度θを測定し、測定装置の測定結果から倣いローラ１３に対するバリ取り切削刃１５の高さ位置を自動調整し、溶接部１２ａのバリを除去する、溶接部バリ取り方法である。
バリ除去対象材１２の端部突合せ角度θを測定し、該測定結果から倣いローラ１３に対するバリ取り切削刃１５の高さ位置を自動調整するので、バリ除去対象材１２の端部突合せ角度θにバラツキがあっても、バリの取り残しや溶接部の削り過ぎを生じることなく、溶接部のバリを除去することができる。
【００１７】
端部突合せ角度θの測定は、たとえばレーザ変位測定機３０を用いて行われる。
レーザ変位測定機３０によるレーザ変位測定では、レーザ光３１をバリ除去対象材１２に投光してその反射光３３をＰＳＤ受光素子３４で受光し、三角測距方式でバリ除去対象材１２の光照射位置３５の、基準位置３６からの変位ｄを求め、該変位ｄに基づいて、バリ除去対象材１２の端部突合せ角度θを、バリ除去対象材１２に非接触で、自動的に、求める。それにより、自動化が可能である。
【００１８】
バリ取り切削刃高さ位置調整を、サーボモータ５１と、バリ取り切削刃をバリ除去対象材の表面に進退する方向に倣いローラに連動させる連動機構１６の一部を構成し、前記サーボモータの回転を前記バリ取り切削刃の高さ方向直線移動に変換する回転／直線変換機構５２とを用いて行うことが望ましい。
これによって、測定装置３０で求められたバリ取り切削刃高さ位置調整量に応じてバリ取り切削刃１５の高さ位置を自動的に調整することができる。それにより、自動化が可能である。
【００１９】
バリ除去対象材の溶接部伸長方向に互いに間隔をもたせて、バリ取り刃１５を２セット設け、バリ取り時送り方向前方に位置するバリ取り刃１５にて溶接部バリ１２ｂを荒切削し、バリ取り時送り方向後方に位置するバリ取り刃１５にて溶接部バリ１２ｂを仕上げ切削するようにすれば、測定装置３０におけるバリ除去対象材の端部突合せ角度θの測定においてバリによる測定誤差が少なくなり、高精度のバリ除去が可能になる。
【００２０】
倣いローラ１３に連動させてバリ取り刃１５をバリ除去対象材１２の表面に倣わせ、バリ１５ｂを除去できるので、バリ除去対象材１２が平板、形鋼、不等厚平板の何れかからなる素材を巻き加工し端部を突き合わせ溶接した環状のホイールリム素材であっても、その端部の突き合わせ溶接部のバリを除去できる。すなわち、形鋼、不等厚平板など表面が凹凸するバリ除去対象材１２であっても、その凹凸にならってバリを除去でき、溶接ばり１２ｂの削り残しや、溶接部の削り過ぎ等の不良を防止することができる。また、バリ取り刃１５の高さ位置も自動調整されるので、高精度で、効率よく（ワーク毎にバリ取り刃１５の高さ位置を調整することなく）、バリ除去を行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a weld deburring device and a weld deburring method, and more particularly to a weld deburring that can be applied to deburring of a welded portion of an annular rim material in which an uneven thickness flat plate, a shape steel, etc. are wound and the end is welded. The present invention relates to a deburring device and a welding part deburring method.
[0002]
[Prior art]
Conventionally, any one of two types of materials, a flat plate-shaped material 1 shown in FIG. 1 and a shaped steel-shaped material 2 shown in FIG. 2, is used for the rim of the wheel. Furthermore, the use of materials such as the unequal thickness material 3 (FIG. 3) shown in Japanese Patent Laid-Open No. 8-91005 is also known.
The manufacturing process of the rim | limb from those raw materials is shown in FIG. In these manufacturing steps, as shown in FIG. 4A, the flat plate is formed with a rim shape mainly by roll forming 7 after winding 4, welding 5, and trimming 6. Regarding the unequal thickness material of Japanese Patent Laid-Open No. 8-91005, as shown in FIG. 4B, the same process as the rim molding from a flat plate is assumed except for the trimming process. The reason is that the production according to the process of Japanese Patent Laid-Open No. 8-91005 has not been carried out. As for the shape steel, since the shape steel has a cross-sectional shape close to the final shape, as shown in FIG. 4 (c), after winding and welding, mainly forming in the radial direction using a split die (sizing) ) 8.
Further, trimming (deburring) after rim welding is performed by moving the cutting tool 9 in the axial direction of the annular material as shown in FIGS. Trim, flat trim). In addition, since the shape steel has irregularities, as shown in FIGS. 6 (a) and 6 (b), the cutting tool 10 having the same shape as the section is moved in the circumferential direction and processed (circumferential trim, rotary Trimmer). Regarding the unequal thickness material of JP-A-8-91005, trimming according to the shape steel is assumed.
The above technique has the following problems.
With flat trimming, the requirements for finished appearance and productivity are almost satisfied for flat plate materials. However, for irregular shaped steel materials and unequal thickness flat plate materials, burrs cannot be removed by rim recesses because flat cutting only moves the cutting tool horizontally.
Further, in the circumferential trim using a rotary trimmer, as shown in FIG. 7, the remaining material 41 of the cutting material 40 is pushed in a subsequent process (molding process, etc.) to generate fog 42, and if left untreated, a notch effect is obtained. In addition to the problem of cracking and cracking due to the occurrence of cracks, the problem of poor appearance is caused, and if it is attempted to remove it, a large amount of cost is required for post-processing as in the case of shape steel.

[Problems to be solved by the invention]
In order to solve the above-described problem, that is, in order to make it applicable to deburring of a deburring target material having a shape with unevenness in the weld extension direction, the applicant has made a copy as shown in FIG. The roller 13 is pressed against the surface of the deburring target material 12 and sent in the direction parallel to the weld extension direction of the deburring target material 12, and the deburring cutting blade 15 is moved in conjunction with the copying roller 13. An apparatus and method for removing burrs from the welded portion of the material to be deburred with the cutting blade 15 are under development.
In the apparatus and method, once the height positions of the copying roller 13 and the deburring cutting blade 15 are adjusted, the positional relationship is fixed. However, in the butt welding, which is a pre-trimming process, there is a variation in the butt angle at the winding start / end portion, so that excessive burrs or un-filled parts occur in the trimming process. For example, in FIG. 8, if a difference occurs in the difference A in the welded portion height due to the difference in the butt angle at the winding start / end portion and the difference B in the roller running portion due to the difference in the butt angle at the winding start / end portion, Excessive burrs and leftovers occur. When this occurs, it is necessary for a person to adjust the height positional relationship between the copying roller 13 and the deburring cutting blade 15 again, but even if the adjustment is made, the variation in the butt angle of the winding start / end portion differs for each workpiece. Therefore, satisfactory adjustment is not possible for all workpieces.
[0005]
An object of the present invention is to remove burrs in a welded portion of an annular material in which a flat plate material, an unequal thickness material or a shaped steel material is wound and the winding start and end portions are welded in conjunction with a copying roller and a deburring cutting blade. In addition, it is an object of the present invention to provide a weld deburring apparatus and a weld deburring method that do not generate excessive or unwelded weld burrs even if there is variation in the butt angle of the winding start and end portions.

[0009]
The copying rollers 13 </ b> A and 13 </ b> B can advance and retract independently from each other in both directions of the burr removal target material 12 in a direction perpendicular to the surface (a direction perpendicular to the surface of the burr removal target material 12).
The roller copying mechanism 14 includes, for example, an L-shaped arm 19 that is rotatably supported around a rotation fulcrum 18 provided on the moving member 17, and a cylinder 20 that is coupled to the L-shaped arm 19. . One L-shaped leg 19a of the L-shaped arm 19 extends in parallel with the extending direction of the welded portion 12a of the burr removal target material 12, and the copying roller 13 and the deburring cutting blade 15 are supported by the leg 19a. ing. A cylinder 20 is provided between the other L-shaped leg 19 b of the L-shaped arm 19 and the moving member 17, and one end of the cylinder 20 is rotatably connected to the moving member 17. The tip of is rotatably connected to the leg 19b. Due to the expansion and contraction of the cylinder 20-the rod 21, the L-shaped arm 19 rotates around the fulcrum 18, and the copying roller 13 and the deburring cutting blade 15 advance and retreat with respect to the deburring target material 12.

So that it is almost in the same position. When the copying roller 13 moves following the shape of the surface of the deburring target material 12, the deburring cutting blade 15 is interlocked with the movement of the copying roller 13 via the interlocking mechanism 16 and the leg 19 a of the L-shaped arm 19. Then, it moves following the shape of the surface of the deburring target material 12.
[0011]
The measuring device 30 for measuring the start / end portion butt angle of the deburring target material 12 is, for example, a laser displacement measuring device (not limited to the laser displacement measuring device). However, in place of the laser displacement measuring machine, the start / end portion abutting angle is set to a position where the copying roller 13 contacts the surface of the burr removal target material 12 (this position is known from the copying roller 13) and a position near the rise of the welding burr. You may obtain | require by the apparatus or the method calculated | required from the difference with the measured value of the contact-type measuring machine which contacts and measures a welding part position.
[0012]
When the measuring device 30 is a laser displacement measuring machine (the reference numeral is 30 because it is the same as the measuring device), as shown in FIGS. 10 and 11, the laser displacement measuring machine 30 converts the laser light 31 into a material to be deburred. A laser irradiating device 32 that irradiates the surface of 12, a PSD light receiving element 34 (“PSD” is an “optical position detecting element”) that receives the (diffused) reflected light 33 and detects the amount of light for each pixel; , And a measuring machine that obtains the displacement d of the light irradiation position 35 of the material to be deburred from the reference position 36 by a triangulation method.
The laser irradiation device 32 emits laser light 31 (cylindrical light, which is spot-shaped irradiation on the workpiece surface) on the cylindrical deburring target material in a plane orthogonal to the axial center of the cylindrical deburring target material. Shake in the circumferential direction over a predetermined range (measurement range). Each pixel of the PSD light-receiving element 34 is in a plane including the axis of the workpiece, and the pixel is scanned to determine which pixel has a large amount of light, so that the reference position 36 of the light irradiation position 35 of the burr removal target material can be obtained. The displacement d can be obtained. A commercially available laser displacement measuring machine can be used for this type of laser displacement measuring machine.
[0013]
The deburring cutting blade height position adjusting mechanism 50 burrs the deburring cutting blade 15 and the servo motor 51 that rotates by the deburring cutting blade height position adjustment from the end butt angle obtained by the measuring device 30 and the workpiece plate thickness. A part of the interlocking mechanism 16 that interlocks with the copying roller 13 in a direction that advances and retreats on the surface of the material to be removed 12 is converted, and the rotation of the servo motor 51 is converted into linear movement in the height direction of the deburring cutting blade. A rotation / linear conversion mechanism 52 (for example, a ball screw mechanism) for adjusting the height position of the cutting blade 15 and a means 53 (for example, a timing belt) for transmitting the rotation of the servo motor 51 to the rotation / linear conversion mechanism 52 are provided. Have.
[0014]
Two (two sets) of deburring cutting blades 15 are provided in the extending direction of the welded portion 12a of the deburring target material 12 at intervals. Of the two deburring cutting blades 15, the deburring cutting blade 15 in front of the deburring cutting blade feed direction is a deburring cutting blade for rough cutting, and among the two deburring cutting blades 15, deburring is performed. The deburring cutting blade 15 behind the cutting blade feed direction is a deburring cutting blade for finish cutting. The rough cutting deburring blade may not be provided, but after the rough cutting deburring cutting blade is provided and the burr is cut, the deburring cutting blade height position adjusting mechanism 50 is measured by the measuring device 30. If the height of the deburring cutting blade for finishing cutting is adjusted and the burr is cut, the influence of the burr on the measurement is reduced, so that high-precision burr removal can be performed.
[0015]
The burr removal target material 12 may be an annular wheel rim material obtained by winding a material made of any one of a flat plate, a shape steel, and an unequal thickness flat plate and butt welding the end portions. In that case, the welded portion 12a is an end butted weld. And the deburring cutting blade 15 is sent to the axial direction of a cyclic | annular wheel rim raw material in parallel with the welding part 12a. In the case of a shape steel or an unequal thickness flat plate, the surface of the material is uneven, and the deburring cutting blade 15 is fed in the axial direction of the wheel rim material while following the unevenness.
[0016]
Next, the weld deburring method of the present invention (which is also an action of the deburring device) performed using the deburring device will be described.
In the welding part deburring method of the present invention, the copying roller 13 (when the copying roller 13 is provided as a pair, the copying rollers 13A and 13B) are respectively pressed against the surface of the burr removal target material 12, and the burr removal target material 12 is welded. The deburring cutting blades 15 (when a pair of deburring cutting blades 15 are provided) are moved in a direction parallel to the extending direction of the portion 12a, and the deburring blades 15A and 15B are moved in conjunction with the copying roller 13. This is a method of removing the burrs 12b of the welded portion 12a of the deburring target material 12 with the cutting blade 15, and measuring the end butting angle θ of the deburring target material 12 with the measuring device 30, and from the measurement result of the measuring device. This is a welding part deburring method in which the height position of the deburring cutting blade 15 with respect to the copying roller 13 is automatically adjusted to remove burrs from the welded part 12a.
The end butt angle θ of the deburring target material 12 is measured, and the height position of the deburring cutting blade 15 with respect to the copying roller 13 is automatically adjusted from the measurement result. Even if there is variation, it is possible to remove the burrs from the welded portion without leaving behind the burrs or causing excessive cutting of the welded portion.
[0017]
The measurement of the end butt angle θ is performed using, for example, a laser displacement measuring device 30.
In the laser displacement measurement by the laser displacement measuring device 30, the laser beam 31 is projected onto the burr removal target material 12, the reflected light 33 is received by the PSD light receiving element 34, and the light of the burr removal target material 12 is measured by the triangulation method. The displacement d of the irradiation position 35 from the reference position 36 is obtained, and the end butting angle θ of the burr removal target material 12 is automatically obtained without contact with the burr removal target material 12 based on the displacement d. . Thereby, automation is possible.
[0018]
Deburring cutting blade height position adjustment comprises servo motor 51 and a part of interlocking mechanism 16 that interlocks the deburring cutting blade with the copying roller in a direction to advance and retreat to the surface of the material to be deburred. It is desirable to use a rotation / linear conversion mechanism 52 that converts the rotation into a linear movement in the height direction of the deburring cutting blade.
Thereby, the height position of the deburring cutting blade 15 can be automatically adjusted according to the deburring cutting blade height position adjustment amount obtained by the measuring device 30. Thereby, automation is possible.
[0019]
Two sets of deburring blades 15 are provided so as to be spaced apart from each other in the weld extension direction of the material to be deburred, and the weld deburring blades 12b are roughly cut by the deburring blade 15 located in front of the feed direction during deburring. If the weld burr 12b is finished and cut with the deburring blade 15 located behind the feed direction during cutting, the measurement error due to the burr in the measurement of the end butt angle θ of the burr removal target material in the measuring device 30 is small. Therefore, high-precision burr removal becomes possible.
[0020]
The deburring blade 15 can be made to follow the surface of the deburring target material 12 in conjunction with the copying roller 13, and the burr 15b can be removed. Therefore, the deburring target material 12 is made of any one of a flat plate, a shape steel, and an unequal thickness flat plate. Even in the case of an annular wheel rim material that has been rolled and butt-welded at the end, burrs at the butt-welded portion at the end can be removed. That is, even if the surface 12 of the burrs to be removed is uneven, such as a shape steel or an unequal thickness flat plate, the burrs can be removed according to the unevenness, and there are defects such as uncut parts of the welding beam 12b and overcutting of the welded parts. Can be prevented. Moreover, since the height position of the deburring blade 15 is also automatically adjusted, deburring can be performed with high accuracy and efficiency (without adjusting the height position of the deburring blade 15 for each workpiece).
[0021]
