The present invention relates to a grinding wheel including a plurality of grinding wheels mounted on a mounting portion, and a grinding wheel mounted on the grinding wheel.
耐火煉瓦や、大理石等の上面は、端面に研削砥石を備えた研削ホイールによって平坦に研削される。当該用途に使用される研削ホイールとしては、回転軸の先端に形成されたマウントに対して着脱自在に装着されるマウント装着部と、その反対側に砥石装着部を備えたホイール基台と、該ホイール基台の該砥石装着部に装着される複数の研削砥石とを備えた研削ホイールが知られている。該研削ホイールに装着される該研削砥石は、ダイヤモンド等の砥粒を周知のボンド材（例えば、ビトリファイド、メタル、レジン）で結合したセグメント砥石と、該セグメント砥石を支持し、該ホイール基台の砥石装着部に装着されるスチールベース（台金）とから構成される（例えば、特許文献１、２を参照。）。 Upper surfaces of refractory bricks and marble are ground flat by a grinding wheel having a grinding wheel on the end surface. As a grinding wheel used in the application, a mount mounting portion that is detachably mounted on a mount formed at the tip of a rotating shaft, a wheel base that includes a grindstone mounting portion on the opposite side, There is known a grinding wheel provided with a plurality of grinding wheels mounted on the wheel mounting portion of the wheel base. The grinding wheel mounted on the grinding wheel supports a segment grindstone in which abrasive grains such as diamond are bonded by a well-known bond material (for example, vitrified, metal, resin), and supports the segment grindstone. It is comprised from the steel base (base metal) with which a grindstone mounting part is mounted | worn (for example, refer patent document 1, 2).
該研削砥石は、該ホイール基台に対して着脱自在に装着されるものであり、研削加工を実施することにより、該研削砥石を構成するセグメント砥石が摩耗した場合は、該ホイール基台から研削砥石を取り外し、新しい研削砥石に取り換えて被加工物に対して再び研削加工を実施することができる。 The grinding wheel is detachably attached to the wheel base. When the segment grinding wheel constituting the grinding wheel is worn by grinding, the grinding wheel is ground from the wheel base.

以下、本発明による研削ホイールについて添付図面を参照して、更に詳細に説明する。 Hereinafter, the grinding wheel according to the present invention will be described in more detail with reference to the accompanying drawings.
図１には、本発明に基づいて構成される研削ホイールの分解図が示されている。図１（ａ）に示すように、研削ホイール２は、後述するマウントに装着されるマウント装着部１０ａと、該マウント装着部１０ａと反対側（裏面側）の砥石装着部１０ｂとを備えたリング状のホイール基台１０と、ホイール基台１０の砥石装着部１０ｂに装着される複数の研削砥石３０と、により構成される。なお、図１（ａ）では、研削砥石３０を２つのみ例示するが、実際には、図示のホイール基台１０に対して周方向に等間隔で８つの研削砥石３０が装着される。 FIG. 1 shows an exploded view of a grinding wheel constructed according to the invention. As shown to Fig.1 (a), the grinding wheel 2 is a ring provided with the mount mounting part 10a with which the mount mentioned later is mounted | worn, and the grindstone mounting part 10b on the opposite side (back surface side) from this mount mounting part 10a. And a plurality of grinding wheels 30 mounted on the wheel mounting portion 10 b of the wheel base 10. In FIG. 1A, only two grinding wheels 30 are illustrated, but in reality, eight grinding wheels 30 are mounted on the illustrated wheel base 10 at equal intervals in the circumferential direction.
ホイール基台１０には、砥石装着部１０ｂに研削砥石３０を結合するためのボルト２０を貫通させる貫通孔１２が複数設けられている。また、研削砥石３０は、金属製のスチールベース３２と、スチールベース３２に対してロウ付けにより結合されるセグメント砥石３４からなっている。図１（ａ）に示すように、本発明に基づき構成される研削砥石３０は、セグメント砥石３４の該スチールベース３２と対向する被支持面の外形が、該スチールベース３２側の支持面の外形よりも小さく形成され、セグメント砥石３４とスチールベース３２とにより、その支持面に段差部３６が形成される。なお、セグメント砥石３４は、ダイヤモンド等からなる砥粒と、該砥粒を結合するためのボンド材（ビトリファイド、メタル、レジン等から適宜選択）とを混合し、所望の形状を得るための金型に装填して焼結し得られる砥石であり、当該形成方法により得られるセグメント砥石の内部構成自体は周知である。また、本実施形態では、セグメント砥石３４をスチールベース３２に対してロウ付けにより結合したが、本発明はこれに限定されず、適宜選択される接着剤により結合することとしてもよい。 The wheel base 10 is provided with a plurality of through holes 12 through which bolts 20 for coupling the grinding wheel 30 to the grinding wheel mounting portion 10b are passed. The grinding wheel 30 includes a metal steel base 32 and a segment grindstone 34 coupled to the steel base 32 by brazing. As shown in FIG. 1 (a), the grinding wheel 30 constructed according to the present invention is such that the outer shape of the supported surface of the segment grindstone 34 facing the steel base 32 is the outer shape of the supporting surface on the steel base 32 side. The stepped portion 36 is formed on the support surface by the segment grindstone 34 and the steel base 32. In addition, the segment grindstone 34 is a mold for obtaining a desired shape by mixing abrasive grains made of diamond or the like and a bond material (appropriately selected from vitrified, metal, resin, etc.) for bonding the abrasive grains. The internal structure of the segment grindstone obtained by the forming method is well known. In the present embodiment, the segment grindstone 34 is bonded to the steel base 32 by brazing. However, the present invention is not limited to this, and may be bonded by an appropriately selected adhesive.
研削砥石３０のスチールベース３２の上部には、２つの雌ねじ孔３２ａが形成されている。雌ねじ孔３２ａは、ホイール基台１０に形成されている貫通孔１２と対応しており、２本のボルト２０を隣接する貫通孔１２、１２に挿入し、ボルト２０の雄ねじ部がスチールベース３２の雌ねじ孔３２ａの雌ねじ部と螺合させられ研削砥石３０がホイール基台１０に固定される。なお、貫通孔１２は、開口部がボルト２０の頭部径よりも大きく形成され、貫通孔１２の内側には、段差部を形成するボルト２０の頭部径よりも小さい小径部が形成されている。そして、該開口部、および該段差部が設けられていることにより、ボルト２０により研削砥石３０をホイール基台１０に締結した場合、図２に示すように、ボルト２０の頭部がホイール基台１０の貫通孔１２の開口部に全体が収容され、ボルト２０の頭部上端が、ホイール基台の１０のマウント装着部１０ａよりも低くなるように形成されている。 Two female screw holes 32 a are formed in the upper portion of the steel base 32 of the grinding wheel 30. The female screw hole 32 a corresponds to the through hole 12 formed in the wheel base 10, and two bolts 20 are inserted into the adjacent through holes 12, 12, and the male screw portion of the bolt 20 is the steel base 32. The grinding wheel 30 is fixed to the wheel base 10 by being screwed into the female screw portion of the female screw hole 32a. The through hole 12 has an opening formed larger than the head diameter of the bolt 20, and a small diameter portion smaller than the head diameter of the bolt 20 forming the stepped portion is formed inside the through hole 12. Yes. And by providing this opening part and this level | step-difference part, when the grinding stone 30 is fastened to the wheel base 10 with the volt | bolt 20, as shown in FIG. The whole is accommodated in the opening portion of the ten through holes 12, and the upper end of the head of the bolt 20 is formed to be lower than the mount mounting portion 10a of the wheel base 10.
研削ホイール２は、図２に示すように、研削装置（全体図は省略する）に配設された回転軸６０の下端に設けられたマウント６２に装着される。マウント６２は、研削ホイール１０の外形と略同形状に形成されており、周方向に等間隔で４つの貫通孔６２ａが穿孔されている。ホイール基台１０には、上記貫通孔６２ａに対応し、マウント装着部１０ａ側から砥石装着部１０ｂ側に貫通する雌ねじ孔１４が形成されている。研削ホイール２のマウント６２に対する装着は、貫通孔６２ａにボルト６４を挿入し、ボルト６４の雄ねじ部をホイール基台１０の雌ねじ孔１４の雌ねじ部に螺合することにより行われ、研削ホイール２は、マウント６２に対して強固に固定される。 As shown in FIG. 2, the grinding wheel 2 is mounted on a mount 62 provided at the lower end of a rotating shaft 60 provided in a grinding apparatus (entire drawing is omitted). The mount 62 is formed in substantially the same shape as the outer shape of the grinding wheel 10, and four through holes 62a are drilled at equal intervals in the circumferential direction. The wheel base 10 is formed with a female screw hole 14 corresponding to the through hole 62a and penetrating from the mount mounting portion 10a side to the grindstone mounting portion 10b side. The mounting of the grinding wheel 2 to the mount 62 is performed by inserting a bolt 64 into the through-hole 62a and screwing the male screw portion of the bolt 64 into the female screw portion of the female screw hole 14 of the wheel base 10. , Firmly fixed to the mount 62.
図３を用いて、本発明に基づいて構成された研削ホイールの作用についてより具体的に説明する。 The operation of the grinding wheel constructed according to the present invention will be described more specifically with reference to FIG.
本実施形態の研削装置は、研削ホイール１０の下方に位置付けられる図示しない保持手段に保持された例えば耐火煉瓦等を研削する。該研削装置の研削ホイール１０は、回転軸６０の上方に配置されたモータにより回転駆動（例えば、２０００ｒｐｍ）されると共に、該保持手段上に固定された被加工物に向けて下方側に加工送り（例えば、０．５ｍｍ／分）される。なお、研削ホイール１０が回転駆動され、被加工物である耐火煉瓦を研削する際には、被加工物の研削面に対して研削水が供給されるため、研削屑が混じって泥状となった研削水が研削砥石３０に付着し、スチールベース３２と、セグメント砥石３４の境界面自体は明確に把握するのが困難となる。 The grinding apparatus of the present embodiment grinds, for example, refractory bricks or the like held by holding means (not shown) positioned below the grinding wheel 10. The grinding wheel 10 of the grinding apparatus is rotationally driven (for example, 2000 rpm) by a motor disposed above the rotation shaft 60 and is fed downward to a workpiece fixed on the holding means. (For example, 0.5 mm / min). In addition, when grinding wheel 10 is rotationally driven and grinds the refractory brick which is a workpiece, since grinding water is supplied with respect to the grinding surface of a workpiece, grinding dust is mixed and it becomes muddy. The ground water adheres to the grinding wheel 30 and it becomes difficult to clearly grasp the boundary surface itself between the steel base 32 and the segment grinding wheel 34.
ここで、本発明に基づいて構成された研削砥石３０は、セグメント砥石３４のスチールベース３２と対向する被支持面の外形が、スチールベース３２側の支持面の外形よりも小さく形成され、セグメント砥石３４がスチールベース３２に対して段差部３６をもって支持されている。よって、図３（ａ）に示す状態では、研削砥石３０のセグメント砥石３４がそれほど摩耗しておらず、段差部３６が明確に残存しており、交換時期が到来するのは、まだまだ先であることが容易に確認できる。さらに、図３（ｂ）に示すように、研削を重ねるにつれて、摩耗が進行したセグメント砥石３４´の研削面がスチールベース３２側に近づく。ここで、図中Ａで示す位置に着目し、セグメント砥石３４´の下面と、該段差部３６との位置関係を確認することにより、泥状の研削水が研削砥石に多少付着していたとしても、摩耗が進行したセグメント砥石３４´の残存量を容易に視覚することができる。また、仮に該泥状の研削水が大量に付着して、視覚によってセグメント砥石３４´の残存量を確認することが困難になっていたとしても、研削ホイール１０が停止している状態で、上記Ａ部を指で触れ段差部３６の状態を確認することにより、セグメント砥石３４´の残存状態を容易に確認することが可能である。 Here, the grinding wheel 30 configured in accordance with the present invention is such that the outer shape of the supported surface of the segment grindstone 34 facing the steel base 32 is smaller than the outer shape of the supporting surface on the steel base 32 side. 34 is supported on the steel base 32 with a stepped portion 36. Therefore, in the state shown in FIG. 3A, the segment grindstone 34 of the grinding grindstone 30 is not worn so much, the stepped portion 36 remains clearly, and the replacement time is still ahead. Can be easily confirmed. Furthermore, as shown in FIG. 3 (b), as grinding is repeated, the ground surface of the segment grindstone 34 'where wear has advanced approaches the steel base 32 side. Here, paying attention to the position indicated by A in the figure, and confirming the positional relationship between the lower surface of the segment grindstone 34 ′ and the stepped portion 36, it is assumed that the muddy grinding water has adhered to the grindstone somewhat. In addition, the remaining amount of the segment grindstone 34 'that has been worn can be easily visualized. Further, even if a large amount of the muddy grinding water adheres and it is difficult to visually confirm the remaining amount of the segment grindstone 34 ′, the grinding wheel 10 is stopped while the grinding wheel 10 is stopped. The remaining state of the segment grindstone 34 ′ can be easily confirmed by touching the A portion with a finger and confirming the state of the stepped portion 36.
本発明の研削ホイールに装着される研削砥石については、セグメント砥石のスチールベースと対向する被支持面の外形を、該スチールベース側の支持面の外形と異形状を成すものであれば、種々の形状を採用することができる。例えば、図１（ｂ）に示す別実施形態の研削砥石４０では、セグメント砥石４４のスチールベース４２と対向する被支持面の外形が、該スチールベース側の支持面の外形と異形状を成すように、スチールベース４２に対して接合されるセグメント砥石４４側の側面に上下方向に延びる凹溝４６を形成している。当該凹溝４６がセグメント砥石３４側に形成されていることにより、上記段差部３６を設けた場合と同様の効果を奏することができ、該研削砥石４０の側面に泥状の研削水が付着しても、視覚、触覚によりセグメント砥石４４の残存量を容易に把握することができる。また、図１（ｃ）に示す別の実施形態としての研削砥石５０では、セグメント砥石５４のスチールベース５２と対向する被支持面の外形が、該スチールベース側の支持面の外形と異形状を成すように、スチールベース５２に対して接合されるセグメント砥石５４の側面に上下方向に延びる凸条５６を形成している。当該凸条５６によっても、上記の段差部３６と同様の作用効果を奏することができる。 As for the grinding wheel mounted on the grinding wheel of the present invention, various shapes can be used as long as the outer shape of the supported surface facing the steel base of the segment grindstone is different from the outer shape of the supporting surface on the steel base side. Shape can be adopted. For example, in the grinding wheel 40 of another embodiment shown in FIG. 1B, the outer shape of the supported surface of the segment grindstone 44 facing the steel base 42 is different from the outer shape of the supporting surface on the steel base side. In addition, a concave groove 46 extending in the vertical direction is formed on the side surface of the segment grindstone 44 to be joined to the steel base 42. By forming the concave groove 46 on the segment grindstone 34 side, the same effect as when the stepped portion 36 is provided can be obtained, and mud grinding water adheres to the side surface of the grinding grindstone 40. However, the remaining amount of the segment grindstone 44 can be easily grasped visually and by touch. In addition, in the grinding wheel 50 as another embodiment shown in FIG. 1C, the outer shape of the supported surface of the segment grindstone 54 facing the steel base 52 is different from the outer shape of the supporting surface on the steel base side. As formed, a ridge 56 extending in the vertical direction is formed on the side surface of the segment grindstone 54 joined to the steel base 52. Also with the ridge 56, the same effect as the stepped portion 36 can be obtained.
