ターシリンダのブレーキ液流通孔の加工方法及び装置に
関するもので、マスターシリンダの加工に広(利用され
るものである。Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a method and apparatus for machining a brake fluid flow hole in a master cylinder used as a braking device of an automobile. It is widely used in the processing of
(従来の技術)
マスターシリンダの中央液圧室とリザーバーとを連通さ
せる2つの貫通孔において小径の貫通孔(以下補償孔と
いう)の加工はシリンダ外側であるリザーバー側より内
側方向へ一般に次の2通りの加工が行われている。(Prior art) In the two through holes that communicate the central hydraulic chamber and the reservoir of the master cylinder, the small diameter through holes (hereinafter referred to as compensation holes) are generally machined inward from the reservoir side, which is the outside of the cylinder, as follows: The street is being processed.
(1)ドリル加工の場合
ドリル加工の場合はブレーキシリンダ素材を固定し外側
より孔明けを行うためにシリンダ内面に大きなパリ及び
切粉が発生する。(1) In the case of drilling In the case of drilling, large burrs and chips are generated on the inner surface of the cylinder because the brake cylinder material is fixed and the hole is drilled from the outside.
このためにドリル加工後シリンダ内よりブラシで切粉を

、設備及び人工がかかり、更にパリとりを行っても多少
パリが残る場合もあり、内面より内視鏡による全数チェ
ックが必要である。For this reason, after drilling, it is necessary to remove chips from the inside of the cylinder with a brush, and then use a reamer to remove the chips. Therefore, three steps are required to process this compensation hole, which requires equipment and manpower.Furthermore, even if deburring is performed, some deburring may remain, and it is necessary to perform a complete check from the inner surface using an endoscope.
(2)放電加工の場合

更に電極等が振れた場合に内面の孔周辺にスパッターが

鏡にて部数チェックする必要がある。(2) In the case of electric discharge machining, electric discharge machining fixes the brake cylinder material and melts the material while applying electrolyte from the outside to drill the hole. Although it does not generate chips, the machining time is extremely long and productivity is low. ,
Furthermore, if the electrode or the like swings, spatter may adhere to the area around the hole on the inner surface, so it is necessary to check the number of copies using an endoscope from the inner surface during this processing as well.

トンカップを破損し油漏れを起こし、更に制動圧が上ら
ず制動できなくなる。In this way, if particles and chips remain on the inner surface of the master cylinder, the piston cup that reciprocates the cylinder will be damaged when the brake is released, causing oil leakage, and furthermore, the braking pressure will not increase, making it impossible to brake.

いる場合は制動力解除時間が長くなるという問題点があ
る。In addition, chips and particles may be removed by the brake fluid pressure before damaging the piston cup, but if the chips fall into the cylinder and get stuck in the valve mechanism that controls the brake pressure, braking force will no longer be obtained. As a result, the brake is difficult to apply, and there is a problem that the braking force release time becomes long, especially when the compensation hole is blocked by cutting burrs or burrs.

ものである。(Problems to be Solved by the Invention) Therefore, the technical object of the present invention is to provide a method and device for machining a compensation hole that does not cause chips or particles to become trapped inside the master cylinder when machining the compensation hole of the master cylinder. It is something.

。(Operation) The above technical means operates as follows. In other words, a part of the taper is provided at the position corresponding to the compensation hole of the punch rod that moves left and right inside the master cylinder, and the cylinder weighs approximately 100 kg.
A punch with a thickness of about 0.5 va is applied from the inside to the outside of the master cylinder by a punch attached to a punch holder that moves accurately up and down along the taper part of the punch rod that is operated by hydraulic pressure. Then, the above-mentioned compensation hole is drilled, and although pars and chips may be generated on the reservoir side, they are not generated on the master cylinder side at all, so there is no need to remove pars or chips. This also eliminates the need for inner laminar processing.
