【考案の詳細な説明】 本考案は管内面研削機の砥石車加圧調整装置に関する。[Detailed explanation of the idea] The present invention relates to a grinding wheel pressure adjustment device for a tube internal grinding machine.
管内面研削機は普通可動台車に設置されていて、中心に
回転軸を有する長い保護ケースを備え、研削砥石車は保
護ケースの先端から外方へ延びた回転軸の先に固定され
る。A tube internal grinding machine is usually installed on a movable cart and has a long protective case with a rotating shaft in the center, and the grinding wheel is fixed to the tip of the rotating shaft that extends outward from the tip of the protective case.
内面研削されるべき長尺の管は研削中回転が与えられる
ように対をなした回転ローラの上に載せられ、而して研
削砥石車を管の内面に当てて回転させるとともに台車を
管に向って移動させることによって管の内面は端から端
まで研削される。A long tube to be internally ground is placed on a pair of rotating rollers to provide rotation during grinding, and a grinding wheel is rotated against the inner surface of the tube while a cart is applied to the tube. By moving in the opposite direction, the inner surface of the tube is ground from end to end.
この際、従来の研削機では砥石車を管の内面に十分に圧
接させるための加圧機構を有しないために、高い研削能
率を期待することができず、又研削量を一定に維持する
ことが不可能であった。At this time, because conventional grinding machines do not have a pressure mechanism to bring the grinding wheel into sufficient pressure contact with the inner surface of the pipe, high grinding efficiency cannot be expected, and it is difficult to maintain the amount of grinding constant. was not possible.
本考案は研削砥石車を管内面に一定加圧で押しつけうる
装置を提供し、これにより一定な研削量を得るとともに
、研削能率の向上を計ることを目的とするものである。The purpose of the present invention is to provide a device that can press a grinding wheel against the inner surface of a tube under constant pressure, thereby obtaining a constant amount of grinding and improving grinding efficiency.
本考案によれば、この目的は、管内面研削機の長い保護
ケースの先端に近い部分の両側に、一対の揺動レバーを

ため、前記揺動レバー間に設けである衝合片と係合する
ブツシャを設けることによって達成される。According to the present invention, this purpose is achieved by pivotally mounting a pair of swinging levers on both sides of a portion near the tip of a long protective case of a tube internal grinding machine, and attaching a pair of swinging levers to the tips of the levers in a forward tilted state. A contact element is provided that does not contact the inner surface of the tube to be ground but engages with the inner surface of the tube in the rearward raised position of the lever, and the external operating rod extending from the grinder is provided with a Swinging of the swinging lever to the raised position is accomplished by providing a button that engages with an abutment piece provided between the swinging levers.
操作棒の後方への移動で揺動レバーが前方傾斜位置から
起上り位置へ揺動されると、先端接触要素(好ましくは
ボールベアリング)が管内面に押しつけられその反力で
砥石車に加圧力が加えられることになる。When the swing lever swings from the forward tilted position to the raised position by moving the operating rod backward, the tip contact element (preferably a ball bearing) is pressed against the inner surface of the tube, and the reaction force applies pressure to the grinding wheel. will be added.
以下本考案の一実施例を添附図面を参照して詳細に記載
すれば次の通りである。Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.
可動台車(図示せず)で支えられた管内面研削機から延

が取付けである。A protective case 1 extending from a tube internal grinding machine supported by a movable cart (not shown) has a rotating shaft 2 at its center;
A grinding wheel 3 is provided in a portion extending outward from the protective case 1.
is the installation.
保護ケース1はその先端に隣接した位置に両端に、上方
に突出したフランジ4,4を有するスリーブ5を一体的
に備え、該スリーブ5のフランジ4と4の中間において
その両側に一対の揺動レバー6.6が軸7,7で枢着さ
れている。The protective case 1 is integrally provided with a sleeve 5 having flanges 4, 4 protruding upward at both ends adjacent to the tip thereof, and a pair of swinging portions on both sides of the sleeve 5 at an intermediate position between the flanges 4, 4. A lever 6.6 is pivotally mounted on axles 7,7.
揺動レバー6.6はその先端に好ましくボールベアリン
グからなる管9の内面に当接して自由回転する接触要素
8,8を備え、これら接触要素は、揺動レバー6.6が
前方に傾斜した位置にあるときには、内面研削されるべ
き長尺の管9の内面に当接せず、レバーが起上り位置に
あるとき管9の内面に係合するようになっている。The swinging lever 6.6 is provided at its tip with contact elements 8, 8 which freely rotate against the inner surface of the tube 9, preferably consisting of a ball bearing, and these contact elements are arranged so that the swinging lever 6.6 is tilted forward. When in this position, the lever does not come into contact with the inner surface of the long tube 9 to be internally ground, but when the lever is in the raised position, it engages with the inner surface of the tube 9.
研削機から延びる操作棒10は、その先端部をフランジ
4,4に設けである孔11.11に通すことによってこ
れらフランジで支えられている。The operating rod 10 extending from the grinding machine is supported on the flanges 4, 4 by passing its tip through a hole 11.11 provided in the flanges 4,4.
操作棒10は、レバー6.6間に連結しである衝合片1
2と係合するブツシャ13を備え、かくして操作棒の後

り揺動レバー6.6はその軸を中心に揺動する。The operating rod 10 is connected between the levers 6 and 6 and has an abutment piece 1.
2, so that when the operating rod is moved rearward, the button 13 pushes against the abutment piece 12, causing the swinging lever 6.6 to swing about its axis.
内面研削されるべき長尺の管9は第2図に示すように普
通対をなした回転ローラ14上に載せられ、これにより
研削中管に回転が与えられる。The elongated tube 9 to be internally ground is typically mounted on a pair of rotating rollers 14, as shown in FIG. 2, which impart rotation to the tube during grinding.

にあってこれに押しつけられることになる。According to the present invention, when the operating rod 10 is pulled from the outside when applying the rotating grinding wheel to the inner surface of the tube 9 for grinding, the button 13 pushes the abutment piece 12. The swinging lever 6.6 pivots rearward about the shafts 7, 7 and rises until the contact elements 8, 8 at its tips are located on the inner surface of the tube and are pressed against this.
かくしてその反力で保護ケース1は下方へ押され、これ
により砥石車3は十分な加圧力で管の内面に圧接される
。The protective case 1 is thus pushed downward by the reaction force, and as a result, the grinding wheel 3 is pressed against the inner surface of the tube with sufficient pressure.
勿論操作棒の引張りを加減することにより砥石車に対す
る加圧力は任意にこれを選定することができる。Of course, the pressure applied to the grinding wheel can be arbitrarily selected by adjusting the tension of the operating rod.
このように本考案によれば、操作棒を外部から操作し、
揺動レバーを介して砥石車に管内面に対する適正加圧力

合が良い。As described above, according to the present invention, the operating rod is operated from the outside,
Grinding efficiency can be significantly increased because the grinding wheel is actively applied with an appropriate pressure force against the inner surface of the tube via the swing lever, and when the pressure is kept constant, it is constant from one end of the tube to the other. It is very convenient to be able to grind with a certain amount of grinding.
