本発明は、磁気ディスク装置等に用いられる磁気ヘッド
を製作する際、巻線溝を有するコア（Ｃコア）“ゝと巻
線溝のないコア（Ｉコア）とのガラス接着時に使用する
治具に関するものである。Detailed Description of the Invention [Industrial Field of Application] The present invention is applicable to manufacturing a magnetic head used in a magnetic disk device, etc., by combining a core with a winding groove (C-core) and a core without a winding groove. This relates to a jig used when bonding glass to a core (I core).
ＣコアとＩコアとをガラス接着する際の治具としては、
従来例えば第２図に示すようなものが使用されている。The jig for glass bonding the C core and I core is as follows:
Conventionally, for example, the one shown in FIG. 2 has been used.
すなわち、上方を開放してほぼＵ字型をした治具本体１
の底板１ａ上に、断面がＩ型をしたＩ型圧着片２と断面
がコ字型をしたコ字型圧着片３とを載置し、さらにこの
コ字型圧着片の背面側に、この背面のほぼ中央に当接す
る突出部４ｂを有し、この突出部４ｂの反対側に底板１
ａに向かって肉厚が厚くなるような勾配面４ａを形成し
た押圧ブロック４と、この押圧ブロック４の勾配面４ａ
に対応する勾配面５ａを有する楔型ブロック５とを配し
たものであり、この楔型ブロック５を底板１ａに向がっ
て押し込むことにより、前記Ｉ型圧着片２とコ字型圧着
片３との間に介装したＩコアとＣコア７とを圧着するよ
うになっている。That is, the jig main body 1 is approximately U-shaped with the upper part open.
An I-shaped crimp piece 2 with an I-shaped cross section and a U-shaped crimp piece 3 with a U-shaped cross section are placed on the bottom plate 1a of It has a protrusion 4b that abuts approximately the center of the back surface, and a bottom plate 1 is provided on the opposite side of the protrusion 4b.
A pressing block 4 having a sloped surface 4a whose wall thickness becomes thicker toward a, and a sloped surface 4a of this pressing block 4.
By pushing this wedge-shaped block 5 toward the bottom plate 1a, the I-shaped crimp piece 2 and the U-shaped crimp piece 3 are arranged. The I core and C core 7 interposed between the two are crimped together.
しかして、前記治具本体１は例えばアルミナ等からなり
、また、■型圧着片２およびコ字型圧着片３は例えばＮ
１−Ｚ、ｎ７エライト等がらなっていて、両圧着片２．
３の熱膨張係数は治具本体１のそれより大になっている
。The jig main body 1 is made of, for example, alumina, and the ■-shaped crimp piece 2 and the U-shaped crimp piece 3 are made of, for example, N
1-Z, n7 elite, etc., and both crimping pieces 2.
The thermal expansion coefficient of No. 3 is larger than that of the jig main body 1.
従って、熱処理の際、治具本体１が熱膨張しても、圧着
片２．３の熱膨張が大であるから、■コア６とＣコア７
に対する圧着力を低下させることなく、■コア６とＣコ
ア７の圧着、保持の状態を維持することがでかのである
。Therefore, even if the jig main body 1 thermally expands during heat treatment, the thermal expansion of the crimp pieces 2.3 is large;
This makes it possible to maintain the state of crimping and holding the core 6 and the C core 7 without reducing the compression force against the core 6 and the core 7.
前記従来の接着治具は、■コア６とＣコア７を圧着する
押圧力の発生を、楔型ブロック５を押し込んで押圧ブロ
ック４の勾配面４ａと楔型ブロック５の勾配面５ａとを
面接触させることによって行なっている。The above-mentioned conventional bonding jig generates a pressing force to press the core 6 and the C-core 7 together by pressing the wedge-shaped block 5 and making the sloped surface 4a of the pressing block 4 and the sloped surface 5a of the wedge-shaped block 5 face up. This is done by making contact.
しかしながら、接触面すなわち勾配面４ａ。However, the contact surface or sloped surface 4a.
５ａの面接触の状態が悪いと、押圧力を均一に持続する
ことが困難であり、この押圧力によるＩコア６とＣコア
７との圧着力が均一に持続しないと、ガラスによるＩコ
ア６とＣコア７との接着が良好にで外ない。If the condition of the surface contact of 5a is poor, it is difficult to maintain the pressing force uniformly, and if the pressing force between the I core 6 and the C core 7 due to this pressing force is not maintained uniformly, the I core 6 made of glass The adhesion between the C core 7 and the C core 7 is excellent.
従って、勾配面４ａ、５ａの面精度を上げる必要がある
が、面精度を向上させることは相当困難である。Therefore, it is necessary to improve the surface accuracy of the sloped surfaces 4a and 5a, but it is quite difficult to improve the surface accuracy.
本発明は、上記従来技術の問題点を解消し、均一な押圧
力を発生させることができる接着治具、を提供すること
を目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide an adhesive jig that can solve the problems of the prior art described above and generate a uniform pressing force.
本発明の接着治具、は、押圧プ１ｆｆ７りの勾配面に凹
所を形成したことを特徴とするものである。The adhesive jig of the present invention is characterized in that a recess is formed in the sloped surface of the pressing plate 1ff7.
押圧ブロックの勾配面に凹所を形成することにより、楔
型ブロックの勾配面との接触面積が減少し、両勾配面の
面精度を容易に向上させることかでトて良好な面接触が
得られ、均一な押圧力を発生することができる。By forming a recess on the sloped surface of the pressing block, the contact area with the sloped surface of the wedge-shaped block is reduced, and the surface accuracy of both sloped surfaces can be easily improved, resulting in better surface contact. It is possible to generate a uniform pressing force.
また、勾配面に凹所を形成することにより押圧ブロック
中央部分の厚さが薄くなって弾力性が増加し、突出部で
のコ字型圧着片の押圧を弾力的に行なうことができる。Further, by forming a recess in the sloped surface, the thickness of the central portion of the pressing block is reduced and its elasticity is increased, so that the U-shaped crimping piece can be pressed elastically by the protrusion.
従って、前記面精度の向上と相まって均一な押圧力を持
続することができるのである。Therefore, in combination with the improvement in surface accuracy, a uniform pressing force can be maintained.
以下、第１図により本発明の一実施例を説明する。 An embodiment of the present invention will be described below with reference to FIG.
第１図は押圧ブロックの拡大斜視図である。FIG. 1 is an enlarged perspective view of the pressing block.
第１図において、突出部４ｂを有する押圧ブロック４の
、前記突出部４の反対側の勾配面４ａに溝状の凹所４ｃ
を形成し、壁４ｄを存置したものである。In FIG. 1, a groove-shaped recess 4c is formed in a sloped surface 4a on the opposite side of the protrusion 4 of a pressing block 4 having a protrusion 4b.
, with the wall 4d remaining.
押圧ブロック４に凹所４ｃを形成し、形成前の厚さに比

向上することができ、さらに壁４ｄの弾力性により押圧
力を突出部４ｂを介しでコ字型圧着片３に均一に持続し
て加えることができるのである。Since the depression 4c is formed in the pressing block 4 and the wall 4d is thinner than the thickness before formation, the surface accuracy of the sloped surface 4a can be improved, and the elasticity of the wall 4d reduces the pressing force. can be uniformly and continuously applied to the U-shaped crimp piece 3 via the protrusion 4b.
