【考案が解決しようとする課題】[Problems to be solved by the device]

これは次のような欠点があった。 (イ) 支軸(6)と,V溝軸座(7)の接合摺動方式は,底面サドル(4) とテーブル(1)と中間サドル(2)の上下回動の動きに対する正確なる直角度 及び平行度の調整を,V溝の修正加工で,容易にその目的を達することを得られ たが,激しく使用するに従ひ,その接合摺動当り部が狭小のため,片減りを生じ て,精度修正を頻繁に行はねばならなくなった。 (ロ) 摺動部は極めて緩い速度で回動するため,注油の減摩効果はなかった 。 本考案は,これらの欠点を除くためになされたものである。 This had the following drawbacks. (A) The joint sliding method of the support shaft (6) and the V-groove shaft seat (7) makes it possible to accurately move the bottom saddle (4), the table (1) and the intermediate saddle (2) vertically. The adjustment of the angle and parallelism could be achieved easily by modifying the V-groove, but as the joint was used violently, the joint sliding contact area was narrow, resulting in uneven wear. As a result, the accuracy has to be corrected frequently. (B) Since the sliding part turns at an extremely slow speed, there was no lubrication reducing effect. The present invention has been made to eliminate these drawbacks.

【作用】[Action]

テーブル(1)は,中間サドル(2)に設けられる送りネジ(3)を,底面サ ドル(4)に突設せる把手(12)と,自在接手(13)により回転せしむるこ とにより,テーブル(1)の中央下面に設けられた雌ネジ(14)によって,上 方砥石軸(15)の下面で往復運動を行ひ,テーブル(1)上の工作物の研削作 業を行ふ。又、中間サドル(2)を上下動調整ネジ(5)にて調整把手(16) の回転で上昇せしむれば,テーブル(1)は中間サドル(2)と共に,支軸(6 )を中心に回動し,砥石下面に於いて,上下動調整ネジ(5)の動き量の約1/ 2寸度の研削代として上昇する。 本方式の平面研削機は,数耗の僅かな研削代に対しては,砥石軸(15)の主 軸ヘッド(17)は,機々本体に固定のまゝで,研削代は前述の通り,テーブル の回動上昇のみで行われる。 研削面の段差の数耗を越へる大いなる時のみ主軸ヘッド(17)の上下動を, ヘッド上下用把手(18)で上下調整するものとする。尚一般には,この様な数 耗の段差分の研削は行われない。 The table (1) is formed by rotating the feed screw (3) provided on the intermediate saddle (2) by the handle (12) protruding from the bottom saddle (4) and the universal joint (13). The reciprocating motion is performed on the lower surface of the upper grindstone shaft (15) by the female screw (14) provided on the lower surface of the center of the table (1) to perform the grinding operation of the workpiece on the table (1). .. Further, if the intermediate saddle (2) is lifted by the rotation of the adjusting handle (16) with the vertical movement adjusting screw (5), the table (1) will be centered on the spindle (6) together with the intermediate saddle (2). When the grinding wheel is moved downward, it rises as a grinding allowance of about 1/2 of the amount of movement of the vertical movement adjusting screw (5) on the lower surface of the grindstone. In this type of surface grinding machine, the spindle head (17) of the grindstone shaft (15) is fixed to the machine body, and the grinding allowance is as described above, even if the grinding allowance is a little worn. , It is done only by the rotation of the table. The vertical movement of the spindle head (17) is adjusted up and down by the head up / down handle (18) only when the number of steps on the grinding surface exceeds the wear. Generally, such grinding of steps due to wear is not performed.

(A) Mount the support shaft (6) on the V-groove seat (7) at the end of the bottom saddle (4) by adjusting the squareness and parallelism with respect to the bottom saddle (4). (B) A bearing (11) is interposed between the two double-sided bearing cases (10) provided at the ends of the intermediate saddle (2) and the both-side protruding shafts (9) of the support shaft (6). (C) When mounting the bearing case (10) on the upper and side surfaces of the bearing case (10), the squareness and parallelism of the ends of the table (1) and the intermediate saddle (2) with respect to the spindle (6) should be obtained. , Perform accurate adjustment processing on the above two sides. According to the above structure, the present plan provides the grinding accuracy by the rotation corresponding to the grinding allowance of the table (1) and the intermediate saddle (2) centering on the both-side protruding shaft (9) of the support shaft (6). The center shaft of the spindle (6) is attached to the V-groove shaft seat (7) provided at the end of the bottom saddle (4) having a grinding parallel reference corresponding to the width of the workpiece so as to keep the work. , It was fixed by adjusting the squareness and parallelism.

【考案の効果】[Effect of the device]

一般に平面研削機の研削代は1粍以下で,現在は,ミクロン単位の僅小の研削 と,研削面の粗度及びウネリが,次の工程の,ラッピング仕上の省力化のために 極小になることが要望されるようになった。 本機は,市販一般型の,砥石軸下降による寸度設定法とは反対に,主軸ヘッド (17)の固定で,従来の主軸ヘッドの如く横振れは皆無となり,テーブル側の 重量物の押し上げによる寸度設定法を用ひたゝめ,切込寸度調整把手(16)の 指示通りの上昇と,且つ,テーブル側の重量化のための振動減衰効果にて,極め て良好なる研削面を得られるようになった。 従って本機の精度維持は中間サドル(2)と底面サドル(4)とを結合する, 支軸(6)の軸受部分の直角度並に平行度の良好なる保持状態を保たしむるため ,支軸(6)の突出軸(9)部に,精度及び耐久性良好なる,ベアリング嵌合と し,他の結合部分は磨粍と緩みのない固定方法としたものである。 Generally, the grinding allowance of a surface grinder is less than one grind, and at present, a small amount of grinding in micron units and the roughness and undulation of the ground surface are minimized to save labor in lapping finish in the next process. Has come to be requested. Contrary to the dimension setting method by lowering the grindstone axis, this machine is fixed to the spindle head (17), so there is no lateral run-out like the conventional spindle head, and the weight of the table side is pushed up. By using the dimension setting method according to, the ascending rise of the cutting dimension adjustment handle (16) and the vibration damping effect for weighting the table side are extremely good for the ground surface. You can get Therefore, in order to maintain the accuracy of this machine, the middle saddle (2) and the bottom saddle (4) are connected, and the bearing state of the support shaft (6) is maintained at a good perpendicularity and parallelism. The protruding shaft (9) of the support shaft (6) is fitted with a bearing that has good accuracy and durability, and the other connecting parts are fixed by abrasion and without loosening.
