本考案は、研削盤における円板状の砥石の周面
を研削して周面形状を矯正する工具に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tool for grinding the peripheral surface of a disc-shaped grindstone in a grinding machine to correct the peripheral surface shape.
種々の部材を円板状砥石の周面に摺接させて研
削を行う研削盤においては、砥石の周面が、研削
作業を反復するに従つて変形して研削に支障を来
たすので、砥石の周面形状を矯正工具により研削
して適正な形状に矯正する必要がある。
In a grinding machine that performs grinding by sliding various parts on the circumferential surface of a disc-shaped grindstone, the circumferential surface of the whetstone deforms as the grinding process is repeated, which hinders grinding. It is necessary to correct the peripheral surface shape into an appropriate shape by grinding with a correction tool.
第6図に示す従来の矯正工具1は、砥石の周面
に摺接する1対のダイヤモンド2,3を、棒状の
工具本体4の遊端面に埋設したものからなつてい
る(例えば特開昭59−30668号公報参照)。 The conventional straightening tool 1 shown in FIG. 6 consists of a pair of diamonds 2 and 3 that are in sliding contact with the circumferential surface of a grindstone and are embedded in the free end surface of a rod-shaped tool body 4 (for example, in Japanese Patent Laid-Open No. 59 -Refer to Publication No. 30668).
上述のような従来の矯正工具1は、工具本体4

ない。
The conventional straightening tool 1 as described above has a tool body 4
The free end surface 4a of the diamond 2, 3 is substantially perpendicular to the center axis L of the tool body 4, and
protrudes from the free end surface 4a by approximately the same amount, so in order to make both diamonds 2 and 3 come into uniform contact with the circumferential surface of the grinding wheel, the tool body 4 must be aligned so that its center axis L accurately aligns with the center of rotation of the grinding wheel. It must be held so that the free end surface 4a is parallel to the tangent that passes through the intersection of the peripheral surface of the grindstone and the central axis L.
しかし、研削盤によつては、ワーク保持台やカ

とが多い。 However, depending on the grinding machine, it may not be possible to orient the center axis L of the tool body 4 accurately to the rotation center of the grindstone due to the relationship with the workpiece holding table, cover, etc.
Or it may be difficult, and in such a case, the tool body 4
Straightening work is often performed with the center axis L of the grindstone pointing in a direction vertically away from the center of rotation of the grindstone.
そうすると、いずれか一方のダイヤモンド2又

みが砥石の周面に片当りして砥石の周面を研削
し、急激に摩耗して、矯正工具1としての寿命が
短くなることとなる。 Then, one of the diamonds 2 or 3 floats in the air, and only the other diamond 3 or 2 makes partial contact with the circumferential surface of the whetstone and grinds the circumferential surface of the whetstone, rapidly wearing out and forming the straightening tool 1. The lifespan of will be shortened.

摩耗が著しく、工具の寿命が短くなる。 Further, a chamfer 4b is formed on the periphery of the free end surface 4a of the tool body 4 to prevent it from coming into contact with the circumferential surface of the grindstone. Therefore, diamond 2,3
The distance D between them becomes shorter, the diameter in which the diamonds 2 and 3 can be embedded becomes smaller, the wear during straightening the grindstone becomes significant, and the life of the tool becomes shorter.

正工具を提供することにある。 The present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to make the tool body such that its center axis L points away from the center of rotation of the grindstone. in support of
In addition to being able to perform straightening work, the pair of diamonds can evenly contact the circumferential surface of the grindstone without uneven contact, and the outer diameter of the tool body is the same as that of conventional tools. Another object of the present invention is to provide a tool for straightening a grinding wheel in a grinding machine, which allows the distance between a pair of diamonds to be larger than that of conventional ones, and allows the use of large-diameter diamonds.

傾斜角αをなすようにして着脱自在に支持されて
いる。 Appropriate fixing part on the right side of the grindstone 6 (not shown)
The rod-shaped tool main body 11 of the straightening tool 9 is held in the grip part 8 of the straightening device provided in the grip part 8 of the straightening tool 9.
It is detachably supported so as to form an appropriate inclination angle α with respect to a straight line A passing through the intersection point P that intersects the line a.
また、工具本体11を、砥石6の回転中心Oを
通る水平な横軸線12より上方に位置させること
により、直線Aは、横軸線12に対して適宜の上
向き傾斜角βをなしている。 Further, by positioning the tool body 11 above the horizontal horizontal axis 12 passing through the rotation center O of the grindstone 6, the straight line A forms an appropriate upward inclination angle β with respect to the horizontal axis 12.
工具本体11の遊端の両側部は、第2図に示す

せている。 Both sides of the free end of the tool body 11 are ground into a tapered shape as shown in FIG. 2 to form a narrow free end surface 11.
It is formed almost wedge-shaped with a remaining. As shown in FIG. 3, this free end surface 11a is inclined upwardly to the left by an inclination angle α', which is the same as the above-mentioned inclination angle α, with respect to a plane B perpendicular to the central axis L of the tool body 11.

Lより等距離の上下位置には、1対のダイヤモン
ド14,15が、その先端部が遊端面11aより
等距離だけ突出するようにして、結合剤16を介
して直角に埋設されている。 A pair of diamonds 14 and 15 are placed above and below the free end surface 11a of the tool body 11 at equal distances from the center axis L, and a bonding agent 16 is applied to the free end surface 11a with the tips of the diamonds 14 and 15 protruding from the free end surface 11a by an equal distance. It is buried at right angles through the hole.
上述のような関係として、工具本体11を砥石
6の周面6aに向けて押しつけると、工具本体1

面6aは、半径の均一な周面に矯正される。 In this state, by rotating the grindstone 6 and moving the straightening tool 9 laterally in the width direction of the grindstone 6, the peripheral surface 6a of the grindstone 6 is corrected to have a uniform radius.
なお、工具本体11の中心軸線Lの向きを常時
同一とした場合、砥石6の半径が小となると、傾
斜角αは大となる。 Note that when the direction of the central axis L of the tool body 11 is always the same, as the radius of the grindstone 6 becomes smaller, the angle of inclination α becomes larger.
したがつて、砥石6の半径の大きさに対応し
て、第3図に示す遊端面11aの傾斜角α′を適正
に定めた矯正工具9を複数種用意しておくのがよ
い。 Therefore, it is advisable to prepare a plurality of types of straightening tools 9 whose inclination angle α' of the free end surface 11a shown in FIG. 3 is appropriately determined in accordance with the radius of the grindstone 6.
以上のように、この実施例によると、ダイヤモ

設することが可能となり、砥石6の矯正における
矯正工具9の寿命を長くすることができる。 Further, the free end surface 11a of the tool body 11 is connected to the grinding wheel 6.
By being parallel to the tangent C on the circumferential surface of
There is no risk that the upper and lower edges of the free end surface 11a will come into contact with the circumferential surface 6a, and therefore, chamfering 4b as in the conventional straightening tool 1 shown in FIG. 6 is not necessary. Therefore, as shown in FIG.
Since the distance D of 5 can be made larger than before,
It becomes possible to embed relatively large diamonds 14 and 15, and the life of the straightening tool 9 for straightening the grindstone 6 can be extended.
第5図は、本考案の別の実施例を示す。 FIG. 5 shows another embodiment of the invention.
この矯正工具19の工具本体21の遊端には大
径部22が形成されている。この大径部2の遊端
面22aは、前記実施例の工具本体11の遊端面
11aと同様に傾斜しており、1対のダイヤモン
ド23,24が埋設されている。 A large diameter portion 22 is formed at the free end of the tool body 21 of this straightening tool 19. The free end surface 22a of the large diameter portion 2 is inclined similarly to the free end surface 11a of the tool body 11 of the previous embodiment, and a pair of diamonds 23 and 24 are embedded therein.
