<技術分野>
本考案は工作機械等のテーブル上に工作物を固
定するのに使用されるTボルトに関するものであ
る。[Detailed Description of the Invention] <Technical Field> The present invention relates to a T-bolt used for fixing a workpiece on a table of a machine tool or the like.
<背景技術>
従来は、第1図,第2図に示すようなTボルト
1が使用されていた。Tボルト1は、頭部1bに
工作機械のテーブル9に形成されたT溝8の上部
の幅より大きな幅を持ち、T溝に係合するように
形成されていた。そのためテーブル9の上面から
頭部1bを挿入できず、テーブル9の端面からT
溝8に頭部1bを挿入して、Tボルト1をT溝8
に沿つて所定の位置まで移動させるので、操作が
面倒で、時間を要する欠点があつた。<Background Art> Conventionally, a T-bolt 1 as shown in FIGS. 1 and 2 has been used. The T-bolt 1 had a head 1b with a width larger than the width of the upper part of the T-groove 8 formed in the table 9 of the machine tool, and was formed to engage with the T-groove. Therefore, the head 1b cannot be inserted from the top surface of the table 9, and the T
Insert the head 1b into the groove 8, and insert the T-bolt 1 into the T-slot 8.
Since the device must be moved to a predetermined position along the curve, the operation is troublesome and time-consuming.
また、第3図,第4図に示すように、テーブル
9の上面から挿入できるように頭部2bに切欠2
c,2dを設けたTボルト2も従来使用されてい
るが、このTボルトはT溝8の下部の側面と頭部
2bの側面とが当接することによつて一方向にの
み回り止めされるようになつているため、切削時
の振動で緩み、逆回りしてTボルト2がずれると
いう欠点があつた。 In addition, as shown in FIGS. 3 and 4, a notch 2 is provided in the head 2b so that the table 9 can be inserted from the top surface.
A T-bolt 2 with grooves c and 2d has also been used conventionally, but this T-bolt is prevented from rotating in only one direction by the contact between the lower side of the T-slot 8 and the side of the head 2b. Because of this, there was a drawback that the T-bolt 2 would loosen due to vibration during cutting, rotate in the opposite direction, and cause the T-bolt 2 to shift.
<目 的>
本考案は、Tボルト3がT溝18の所定の位置
まで短時間で容易に移動でき、しかも切削時の振
動ではずれないようにすることを目的とする。<Purpose> The purpose of the present invention is to enable the T-bolt 3 to be easily moved to a predetermined position in the T-slot 18 in a short time, and to prevent it from coming off due to vibration during cutting.
<実施例>
以下本考案の実施例を図面に基づいて説明す
る。第7図は本考案のTボルト3を使用した工作
物Wの締め付け状態を示すもので、19はテーブ
ルで、このテーブル19上には縦および横方向に
直交してT溝18が形成されている。<Examples> Examples of the present invention will be described below based on the drawings. FIG. 7 shows the tightening state of a workpiece W using the T-bolt 3 of the present invention. Reference numeral 19 denotes a table, on which a T-slot 18 is formed perpendicularly in the vertical and horizontal directions. There is.
前記Tボルト3は第5図および第6図に示すよ
うに、前記T溝18に係合する頭部3bと軸部3
aとからなつている。頭部3bの各側面のほぼ中
央部には、開き角度90度のV字状の溝3cが軸部
3aの軸線と平行な方向に沿つて形成されてお
り、それによつて頭部3bはX字状の溝3cをT
溝18の交差部の4角に対応させた第5図2点鎖
点の状態でテーブル19の上方よりT溝18に挿
入できるようになり、かつT溝18との係合によ
り回り止めされている。したがつてテーブル19
上に工作物Wを固定する場合には、Tボルト3を
セツトすべき位置に最も近いT溝18の交差部よ
り頭部3bを挿入でき、Tボルト3のセツトを短
時間でかつ容易に行なえるようになる。 As shown in FIGS. 5 and 6, the T-bolt 3 has a head 3b that engages with the T-slot 18 and a shaft portion 3.
It consists of a. A V-shaped groove 3c with an opening angle of 90 degrees is formed in a direction parallel to the axis of the shaft portion 3a at approximately the center of each side surface of the head 3b, thereby allowing the head 3b to T-shaped groove 3c
It can be inserted into the T-groove 18 from above the table 19 in the state of the two-dot chain point shown in FIG. There is. Therefore table 19
When fixing the workpiece W on top, the head 3b can be inserted from the intersection of the T grooves 18 closest to the position where the T-bolt 3 is to be set, and the T-bolt 3 can be set easily and in a short time. Become so.
<効 果>
以上述べたように本考案によれば、T溝18が
交差したところから頭部3bを挿入できるため、
Tボルト3を所定の位置までT溝18に沿つて移
動させる時間を短くできる特徴がある。しかも、
TボルトはT溝18の中で回り止めされているた
め、切削時の振動で緩んだり、Tボルト3がT溝
18からはずれることがないというメリツトが得
られる。<Effects> As described above, according to the present invention, since the head 3b can be inserted from the point where the T-slots 18 intersect,
A feature is that the time required to move the T-bolt 3 to a predetermined position along the T-slot 18 can be shortened. Moreover,
Since the T-bolt is prevented from rotating within the T-groove 18, there is an advantage that the T-bolt 3 will not loosen due to vibration during cutting and will not come off from the T-groove 18.
