Description
本発明は、比較的非圧縮性の研磨材被覆ペーパーと、該ペーパー研磨材被覆面を回転される加工面を有する鋼管、自動車部品等の被加工物表面に、接触させ押圧する比較的剛性の凹面を有するペーパーラップシューとからなり、研磨材被覆ペーパーを使用して被加工物表面を極めて精密にミクロ仕上げするペーパーラップ装置のペーパーラップシューに関する。 The present invention provides a relatively incompressible abrasive-coated paper, a relatively rigid material that is brought into contact with and pressed against a workpiece surface such as a steel pipe or an automobile part having a processed surface that is rotated. The present invention relates to a paper wrap shoe for a paper wrap apparatus, which comprises a paper wrap shoe having a concave surface and microfinishes the surface of a work piece with high precision using an abrasive-coated paper.
従来の比較的非圧縮性の研磨材被覆ペーパーと、該ペーパー研磨材被覆面を被加工物表面に接触させ押圧する剛性凹面を有する一対のペーパーラップシューとからなり、研磨材被覆ペーパーを使用して被加工物表面を極めて精密にミクロ仕上げするペーパーラップ装置のペーパーラップシューとしては、例えば特許文献１の図２（ａ）には、一対の開閉アームに断面Ｕ字形のシューホルダーを介して支持された比較的剛性の凹面を有するペーパーラップシューが一対の支点ピンでシューホルダーに支持され、ペーパーラップシューは被加工物の軸方向に揺動可能にかつ該支点ピンの軸方向に移動可能に隙間を持ってシューホルダーを介して一対の開閉アームに支持されたものが開示されている。
しかしながら、特許文献１に示すペーパーラップ装置のペーパーラップシューでは、各ペーパーラップシューが一対の支点ピンでシューホルダーに支持され、被加工物の軸の回りに垂直方向の角度のズレに対して揺動可能に支持され、かつペーパーラップシューは被加工物の軸方向に揺動可能に支持されているが、ペーパーラップシューの軸心と被加工物の軸心とが互いにずれているとき、即ち被加工物の軸の回りに垂直な方向に直交する直角方向の角度のズレがあるとき、このずれの方向にペーパーラップシューの保持力以上の外力がペーパーラップシューに加えられたとき、ペーパーラップシューは被加工物の軸に片当たりして均等に密着せず被加工物の軸表面の均一な仕上がりが得られなかった。特許文献２では、図１−図６、明細書９頁９−１６行にはアーム部材（３０）に固定された連結ピン（４４）が球面軸受（４４ａ）に固定され、連結ピン（４４）に固定された球面軸受（４４ａ）が、接触シュー（４０）の一端部と連結ピン（４４）とを一方が他方に対して球面運動するように連結していることにより、接触シュー（４０）の断面円弧状の凹面が、被加工物の軸方向に対して直角な面上をフローティングすることを開示する。しかしながら、接触シュー（４０）の一端部が球面軸受（４４ａ）に支持され、極めて僅かの角度しかフローティングできず、かつ球面軸受（４４ａ）は複雑高価で摩耗しやすいなどの課題があった。 However, the paper wrap shoe shown to Bae Parappu device in Patent Document 1, the paper wrap shoe is supported on the shoe holder by a pair of pivot pins, with respect to deviation around the vertical angle of the axis of the workpiece The paper wrap shoe is supported so as to be swingable, and is supported so as to be swingable in the axial direction of the workpiece, but when the axis of the paper wrap shoe and the axis of the workpiece are shifted from each other, In other words, when there is a deviation of a right angle perpendicular to the direction perpendicular to the axis of the workpiece, when an external force exceeding the holding force of the paper wrap shoe is applied to the paper wrap shoe in this direction of deviation, the paper The lap shoe hits the shaft of the work piece and does not adhere evenly, so that a uniform finish of the shaft surface of the work piece could not be obtained. In Patent Document 2, the connection pin (44) fixed to the arm member (30) is fixed to the spherical bearing (44a) in FIGS. A spherical bearing (44a) fixed to the contact shoe (40) connects one end portion of the contact shoe (40) and the connecting pin (44) so that one of them is spherically moved with respect to the other, whereby the contact shoe (40). of arcuate cross section concave, discloses the Freund Ti ing a perpendicular Menjo to the axial direction of the workpiece. However, one end of the contact shoe (40) is supported by the spherical bearing (44a), it can only flow Ti ing very small angle, and the spherical bearing (44a) has a problem such as subject to wear in complex expensive .
本発明の課題は、かかる従来製品の課題を解決した、ペーパーラップシューの軸心と被加工物の軸心とが被加工物の軸方向に対して直角な面上で互いにずれており、このずれの方向にペーパーラップシューの保持力以上の外力がペーパーラップシューに加えられたとき、ペーパーラップシューの断面円弧状の凹面が、被加工物の軸方向に対して直角な面上を大きい角度でフローティングすることができ、ペーパーラップシューが被加工物の軸に片当たりすることがなく被加工物の軸に均等に密着させて、被加工物の軸表面の均一な仕上がりが得られるような、極めて簡単、安価で耐摩耗性がある、ペーパーラップ装置のペーパーラップシューを提供することにある。 The problem of the present invention is to solve the problem of the conventional product, the axis of the paper wrap shoe and the axis of the workpiece are shifted from each other on a plane perpendicular to the axial direction of the workpiece. When an external force greater than the holding force of the paper wrap shoe is applied to the paper wrap shoe in the direction of displacement, the concave surface of the paper wrap shoe having an arcuate cross section has a large angle on the surface perpendicular to the axial direction of the workpiece. in can furo Ti packaging, paper wrap shoe by uniformly adhered to the axis of the workpiece without having to uneven contact to the axis of the workpiece, a uniform finish of the shaft surface of the workpiece is obtained An object of the present invention is to provide a paper wrap shoe for a paper wrap apparatus that is extremely simple, inexpensive and wear-resistant.
このため本発明は、研磨材被覆ペーパーの研磨材被覆面をクランクシャフトを含む軸物の被加工物表面に接触させ押圧する一対の開閉アームに断面Ｕ字形のシューホルダーを介して支持された凹面を有するペーパーラップシューを含むペーパーラップ装置において、前記ペーパーラップシューは前記シューホルダーにペーパーラップシューに固定した一対の支点ピンにより前記開閉アームに対し前記被加工物の軸方向に揺動可能にかつ該支点ピンの軸方向に移動可能に隙間を持って支持され、前記開閉アーム、シューホルダー及びペーパーラップシューのそれぞれ中央に設けた穴に嵌合する中央ピン及び前記開閉アームとシューホルダーとの間に挟んだワシャーを介して、前記シューホルダー及びペーパーラップシューを前記開閉アームに対し前記中央ピンの回りにフローティングするよう揺動可能に支持したことを特徴とするペーパーラップ装置のペーパーラップシューを提供することによって上記した従来製品の課題を解決した。 Thus the present invention, Ken Migakuzai coated paper concave abrasive coated surface is supported via a shoe holder U-shaped cross section to a pair of opening and closing arms for pressing into contact with the workpiece surface of the shaft comprising a crankshaft The paper wrap shoe includes a paper wrap shoe having a pair of fulcrum pins fixed to the shoe holder on the paper wrap shoe so as to be swingable in the axial direction of the workpiece with respect to the open / close arm.
