Description

本発明は、穴あけ作業後に、穴の開放端面の角の面取りを行う、特に、作業者が手に握って作業を行う手作業用面取り装置に関するものである。   The present invention relates to a chamfering device for manual work that chamfers the corners of the open end face of a hole after the drilling work, and in particular, the work is carried out by an operator holding it in his hand.

作業者が手に握って作業を行うハンディタイプの面取り装置では、従来から穴の入口端面の面取りはテーパー形状の工具（例えば、エアーマイクログラインダー）を使用して簡単に面取り加工を行うことが可能であるが、反対側の穴の奥の端面の面取りでは、作業者が穴の奥に手を挿入し、やすり等の手工具で小量ずつ面取り加工を行わねばならないという問題があった。   With a handy type chamfering device that is held by the operator's hand, the chamfering of the entrance end surface of the hole can be easily chamfered using a tapered tool (for example, an air micro grinder). However, in the chamfering of the end face at the back of the hole on the opposite side, there is a problem that the operator must insert a hand into the back of the hole and perform chamfering by small amounts with a hand tool such as a file.

一方で、特許文献１には、回転可能にチャックに固定されたボディの内部に面取り用のブレードを収容し、ボディの回転による遠心力を利用してブレードを収納窓から突出させて面取り部に対して位置決め調整後所定の回転を行うことにより面取り加工を行う技術が開示されており、この技術によれば反対側の穴の奥の端面についても同様に面取りを行うことができる。しかし、手作業用のハンディタイプの面取り装置における回転軸状部にブレードの収納部や収納窓などの複雑な構成を備えることは困難であり、このような複雑な構成の技術をそのままハンディタイプの面取り装置に転用することは困難である。   On the other hand, in Patent Document 1, a blade for chamfering is accommodated inside a body that is rotatably fixed to a chuck, and the blade is projected from a storage window by using centrifugal force due to rotation of the body to be a chamfered portion. On the other hand, a technique for performing chamfering by performing a predetermined rotation after positioning adjustment is disclosed, and according to this technique, chamfering can be similarly performed on the end face of the hole on the opposite side. However, it is difficult to provide a complicated configuration such as a blade storage portion or a storage window in the rotating shaft-shaped portion in a hand-held chamfering device for manual work. It is difficult to divert to a chamfering device.

また、特許文献２には、穴あけ工具のドリル先端の穴あけ刃の近傍位置に直方体状の溝を設けて、溝内に配設された回動可能なアーム部材にバネと錘を付設し、ドリルの回転数を調整することによりバリ取りチップの突出量の調整を行うバリ取り機能付き穴あけ工具が開示されており、この技術によれば反対側の穴の奥の端面についても同様にバリ取りを行うことができる。しかし、特許文献１と同様に、このような複雑な構成の技術をそのままハンディタイプの面取り装置に転用することは困難である。   In Patent Document 2, a rectangular parallelepiped groove is provided in the vicinity of the drilling blade at the drill tip of the drilling tool, and a spring and a weight are attached to a rotatable arm member disposed in the groove. A drilling tool with a deburring function that adjusts the protruding amount of the deburring tip by adjusting the rotation speed of the deburring tip is disclosed. According to this technique, the deburring of the back end face of the opposite hole is similarly performed. It can be carried out. However, as in Patent Document 1, it is difficult to divert the technology having such a complicated configuration as it is to a handy type chamfering apparatus.
