１１のロッド端に孔あけゲージ１０を取り付けている。The positioning device 1 includes a hydro cylinder 2 which is vertically installed from a base and serves as a lifting means with a small stroke, an air fryer 12 attached to the rod end of the hydro cylinder 2, and a mounting plate 3 on which a green green molded body W is placed. , an air cylinder 5 attached to the frame 4 facing downward above this mounting plate 3, and a piston rod 6 of this air cylinder 5.
It consists of a positioning jig 7 and a bracket 14 which are locked at one end, and a photoelectric sensor 8 for detecting the upper end 13 of the green material molded body W is attached to one end of the bracket 14, and an air cylinder 11 is attached to the other end. A hole gauge 10 is attached to the rod end of this air cylinder 11.

れている。The distance between the charging sensor 8 and the air cylinder 11 in the height direction varies depending on the product. Further, the shape of the positioning jig 7 is determined by following the shape of the inner circumference W1 of the target green molded body W, that is, the shape of the positioning part opened upward, and the first body 7a shown above is slightly smaller than the inner circumference W1. The second body part 7b below it has a tapered shape that becomes thinner toward the bottom, and the third body part 7C below it has a tapered shape that becomes even thinner.
以上の構成からなる孔あけ装置の動作をつぎに述べる。The operation of the drilling device having the above configuration will be described next.
第１図において、載置板３上に図示せぬ手段で生素地成
形体Ｗを仮心出し状態で載置するにの時ハイドロシリン
ダ２が縮んでいるので、載置板３はベースの一部である
ストッパ９．９に支承されている。In FIG. 1, since the hydro cylinder 2 is contracted when the green green molded body W is placed on the placement plate 3 in a tentatively centered state by means not shown, the placement plate 3 is placed in the same position as the base. It is supported on a stopper 9.9 which is a part.

矢印Ｅのごとく下降させる。Next, as shown in FIG. 2(a) which is an explanatory diagram of the operation, the rod of the hydro cylinder 2 is extended and the air fryer 12 is
, lift the mounting plate 3 upwards from the stopper 9.9 and separate it slightly. Subsequently, the piston rod 6 of the upper air cylinder 5 is advanced at high speed, and the positioning jig 7 is lowered as shown by arrow E.

ヤ１２を作動させ載置板３を浮動状態とし、生素地成形
体Ｗが僅かな水平力で水平方向に移動可能とする。続い
て第２胴部７ｂが内周Ｗ１を押して更なる荒位置決めを
する。First, the third body 7C of the positioning jig 7 enters the inner periphery W1 to roughly center the green body molded body W, and at the same time operates the air fryer 12 to make the mounting plate 3 in a floating state, thereby forming the green body. A body W can be moved in the horizontal direction with a slight horizontal force. Subsequently, the second body portion 7b pushes the inner periphery W1 for further rough positioning.
第１胴部７ａが少し内周Ｗ１にかかったところで、第２
図（ａ）に示す如くピストン５ａがシリンダエンドに当
たって止まり、位置決め治具７は下降を停止する。When the first body portion 7a slightly touches the inner circumference W1, the second body portion 7a
As shown in Figure (a), the piston 5a hits the cylinder end and stops, and the positioning jig 7 stops descending.
シリンダ５の停止信号を受けた下部のハイドロシリンダ
２は、低速で生素地成形体Ｗを更に上昇せしめる（第２
図（ｂ）参照）。Upon receiving the stop signal from the cylinder 5, the lower hydro cylinder 2 further raises the green body formed body W at low speed (second
(See figure (b)).

Ｗの内周Ｗ１に作用して微調整位置決めを完了する。When the charging sensor 8 provided at one end of the bracket 14 detects the upper end 13 of the rising green body W, the expansion of the hydro cylinder 2 is stopped, the operation of the air fryer 12 is stopped, and the first cylinder of the positioning jig 7 is stopped. The portion 7a acts on the inner periphery W1 of the green molded body W to complete fine adjustment positioning.
その後、エアシリンダ１１を作動させてロッド先端の孔
あけゲージ１０を前進させ生素地成形体Ｗを突き抜けて
、位置決め治具７の第１胴部７ａに孔あけゲージ１０の
先端が突き当る。その後孔あけゲージ１０を後退させて
孔あけを完了する。Thereafter, the air cylinder 11 is actuated to advance the hole gauge 10 at the tip of the rod so that it passes through the green molded body W, and the tip of the hole gauge 10 abuts against the first body 7a of the positioning jig 7. Thereafter, the drilling gauge 10 is moved back to complete the drilling.
本実施例では、生素地成形体の上端を検出した後、孔を
あけるので常に生素地成形体の上端を基準に一定の位置
に孔をあけることができる。In this embodiment, the holes are drilled after the upper end of the green molded body is detected, so that the holes can always be drilled at a constant position with respect to the upper end of the green molded body.
また、位置決め治具を吊り下げたエアシリンダ５は、中

いて、位置決め治具の下降速度を切り換えて、高速で荒
位置決め、低速で微調整位置決めを行ってもよい。Further, since the air cylinder 5 on which the positioning jig is suspended operates until the end of the stroke without stopping in the middle, the air cylinder 5 has a simple mechanism and maintenance is easy. Hanging the positioning jig is not limited to the above-mentioned air cylinder, but it is also possible to use a hydro cylinder, electric cylinder, etc., and change the lowering speed of the positioning jig to perform rough positioning at high speed and fine adjustment positioning at low speed. .
また、孔あけは位置決め完了後、位置決め治具を生素地
成形体空間部から移動させた後、別の孔あけ装置が移動
してきて孔をあけてもよい。Alternatively, after the positioning is completed, the positioning jig is moved from the space of the green molded body, and then another hole-drilling device is moved to make the holes.
