Description

この発明は、液体ホーニング加工用ワーク旋回装置、詳しくは、従来のものより、停止位置を多く設定出来、位置決め精度も良好な液体ホーニング加工用ワーク旋回装置に関するものである。   The present invention relates to a work swiveling device for liquid honing, and more particularly to a work swiveling device for liquid honing that can set more stop positions and has better positioning accuracy than conventional ones.

加工室内に保持された加工対象物に向って研磨材と水からなるスラリーを噴射して、表面研磨やバリ取りなどを行う液体ホーニング加工は、機械部品製造の際などに多く採用されている。   A liquid honing process in which a slurry made of an abrasive and water is sprayed toward an object to be processed held in a processing chamber to perform surface polishing, deburring, and the like is often employed in manufacturing machine parts.

なしNone

なしNone

液体ホーニング加工において、対象物即ちワークの所望の部位、特にワークに形成されている穴交差部にスラリーを適切に衝突させるには、ワークと噴射ガンの相対位置を変更出来る様になっていることが必要であり、この目的の為、加工室内においてワークを旋回出来る様にしたものが多い。   In liquid honing, the relative position of the workpiece and the spray gun can be changed to allow the slurry to properly collide with the object, that is, the desired part of the workpiece, especially the hole intersection formed in the workpiece. For this purpose, many workpieces can be turned in the machining chamber.

従来において、このワークの旋回には、エアシリンダーによってラック／ピニオンを駆動し、ワークを枢支軸を中心として旋回させ、ストッパに突き当てることにより、所望角度で停止させる仕組みが多く用いられていた。   Conventionally, for the turning of the work, a mechanism is often used in which the rack / pinion is driven by an air cylinder, the work is turned around a pivotal support shaft, and stopped at a desired angle by abutting against a stopper. .

しかしながら、この方式では、ワークの停止位置を多く設定することがむずかしく、停止位置は最大でも３つが限度であり、４つ以上の停止位置を設けようとするには、噴射ノズルを動かす機構が別途必要となり、装置全体が複雑化し、それに伴うコストアップも避けられなかった。又、この方式では位置決め精度が悪く、装置の芯出しもむずかしかった。   However, in this method, it is difficult to set a large number of workpiece stop positions, and the maximum number of stop positions is three. In order to provide four or more stop positions, a mechanism for moving the injection nozzle is separately provided. As a result, the entire apparatus becomes complicated, and the accompanying cost increase is inevitable. Further, this method has poor positioning accuracy, and it is difficult to center the apparatus.

本発明は、液体ホーニング加工の際のワークの旋回に関する上記問題点を解決する為になされたものであり、位置決め精度が良く、装置の芯出しも容易で、停止位置が多く設定出来、しかも、位置決めの為のストッパをなくす事により、メンテナンス性も向上した新しい液体ホーニング加工用ワーク旋回装置を提供せんとするものである。   The present invention was made in order to solve the above-mentioned problems related to the turning of the workpiece during liquid honing, positioning accuracy is good, the centering of the apparatus is easy, and many stop positions can be set, By eliminating the stopper for positioning, we intend to provide a new work swiveling device for liquid honing with improved maintainability.

箱形をした加工室内の対向した一対の側面を貫通して、水平かつ同軸状に対向して軸支せしめられた基準ピンと押付ピン及び前記基準ピンに付帯し、前記基準ピンから偏心した位置に設けられた突起のそれぞれの先端部で加工対象物であるワークを両側から押圧保持する様になっており、基準ピンの基部には、加工室外に固定されたロータリーアクチュエータの駆動軸が同軸状に連結されており、該駆動軸によって基準ピンを回動させることにより、ワークを任意の角度で旋回停止させられる様して、上記課題を解決した。 A pair of side surfaces facing each other in a box-shaped processing chamber are attached to the reference pin, the pressing pin, and the reference pin that are horizontally and coaxially opposed to each other and attached to the reference pin. The workpiece, which is the object to be processed, is pressed and held from both sides at the tip of each of the projections provided, and the drive shaft of the rotary actuator fixed outside the processing chamber is coaxial with the base of the reference pin. The above-described problems have been solved so that the work can be stopped at an arbitrary angle by rotating the reference pin by the drive shaft.

基準ピンと押付ピン及び前記基準ピンに付帯し、前記基準ピンから偏心した位置に設けられた突起によってワークを両側から押圧保持し、ロータリーアクチュエータを駆動して基準ピンを所望の回転角だけ回転させ停止させることにより、ワークを順次所望の回転角だけ変位させつつ、図示を省略した噴射ノズルからスラリーをワークの所望部位に向かって噴射して、ワーク表面やワークに形成されている穴交差部のバリ取りや研磨等の加工作業を行う。
この際、駆動源としてロータリーアクチュエータを用いているので、従来のラック／ピニオン方式のものとは異なり、位置決め用のストッパーを必要とせず、ワークを任意の角度で自由に変位させることが可能で、噴射ノズルを動かす機構を別途用意する必要もなく、装置全体を簡略化することが可能で、それに伴い調整も容易で、メインテナンス性が向上し、故障のおそれも少なく、製造コストも低くすることが可能である。又、装置全体の構成が単純で、装置の芯出しも容易であり、回転、停止時にワークがスリップするおそれもなく、位置決め精度も良好で、ワークを所望の回転角で正確に停止出来るので、精度の高い加工が可能となる効果を有し、高い実用性を有する。 Attached to the reference pin , the pressing pin, and the reference pin, the workpiece is pressed and held from both sides by a protrusion provided at an eccentric position from the reference pin , and the rotary actuator is driven to rotate the reference pin by a desired rotation angle. By stopping, the workpiece is sequentially displaced by a desired rotation angle, and slurry is sprayed from a spray nozzle (not shown) toward a desired portion of the workpiece, so that the workpiece surface and the hole intersection portion formed on the workpiece are Perform processing operations such as deburring and polishing.
At this time, since a rotary actuator is used as a drive source, unlike a conventional rack / pinion system, a positioning stopper is not required, and a workpiece can be freely displaced at an arbitrary angle. There is no need to prepare a separate mechanism for moving the injection nozzle, and the entire device can be simplified, making adjustments easier, improving maintenance, reducing the risk of failure, and reducing manufacturing costs. Is possible. In addition, the overall configuration of the device is simple, centering of the device is easy, there is no risk of the workpiece slipping when rotating or stopping, the positioning accuracy is good, and the workpiece can be stopped accurately at the desired rotation angle . It has the effect of enabling highly accurate processing and has high practicality.

Protrusions 21 are also formed at locations deviated outwardly from the axis of the tip portion 15, and are driven by being fitted into the concave holes 19 formed at the corresponding positions of the end portion 17 of the work 16. A rotational force is reliably transmitted from the shaft 14 to the workpiece 16.

なお、この実施例１において、図示されているワーク１６は、ガソリンエンジンやディーゼルエンジンなどレシプロ機関のクランクシャフトであるが、両端を軸支して加工室１の内部空間２に保持出来る様な形状の部材であれば、他のものでも良いことはもちろんである。   In the first embodiment, the illustrated workpiece 16 is a crankshaft of a reciprocating engine such as a gasoline engine or a diesel engine, but is shaped so as to be supported in the internal space 2 of the processing chamber 1 with both ends pivotally supported. Of course, other members may be used.

一方、押付ピン９側の保持板１２’上には、押付ピン９の基部１１が取付けられており、該押付ピン９の先端部２２は、加工室１の内部空間２内において基準ピン９の先端部１５と向かい合う様に位置せしめられており、更にこの押付ピン９は、図示を省略したエアシリンダ、電磁ソレノイド等の駆動源により、軸芯方向に先進／後退することが出来る様になっている。   On the other hand, the base 11 of the pressing pin 9 is mounted on the holding plate 12 ′ on the pressing pin 9 side, and the tip 22 of the pressing pin 9 is connected to the reference pin 9 in the internal space 2 of the processing chamber 1. The pressing pin 9 can be advanced / retracted in the axial direction by a driving source such as an air cylinder or an electromagnetic solenoid (not shown). Yes.

又、この押付ピン９の先端部２２の軸芯には、ワーク１６のもう一方の端部２３の軸芯に形成されている凹穿部２４に嵌め込まれる突起２５が形成されている。   Further, a projection 25 is formed on the axial center of the tip end portion 22 of the pressing pin 9 so as to be fitted into a concave hole portion 24 formed on the axial center of the other end portion 23 of the workpiece 16.
