Description
本發明為有關一種氣動工具,尤指一種氣動工具之供氣結構。The invention relates to a pneumatic tool, in particular to a gas supply structure of a pneumatic tool.
氣動工具是利用空氣壓縮機提供的壓縮空氣帶動氣動馬達而對外輸出動能工作的一種工具,其具有運動較快、適應性強、可在易然、易爆、多沉、潮濕、衝擊的惡劣環境中工作,不污染環境,工作壽命長,構造簡單,便於維護等優點,而被廣泛的應用於現代機械製造、船舶製造、汽車製造、汽車修配、建築裝潢、石材加工等許多領域。The pneumatic tool is a tool that uses the compressed air provided by the air compressor to drive the air motor to output the kinetic energy. It has the characteristics of quick movement, strong adaptability, and can be easily, explosive, heavy, wet and impact. It has been widely used in many fields such as modern machinery manufacturing, shipbuilding, automobile manufacturing, automobile repair, building decoration, stone processing, etc., with its advantages of non-polluting environment, long working life, simple structure and easy maintenance.

然而,在製作該氣動工具之外殼時,該控氣通道都是利用砂心模的方式來製作,其係於製作該外殼時先行埋砂於該控氣通道的位置,接著再於完成外殼之製作後,移除埋設於該控氣通道位置的砂子,進而形成該控氣通道,而在製作外殼時,容易因沒控制好埋砂時砂子的數量或砂心強度不足造成崩壞,而產生該控氣通道大小不一或無法連通該汽缸座的瑕疵,使製作良率下降,因此如何減少該控氣通道的瑕疵,實為業者所努力的目標。However, when the outer casing of the pneumatic tool is manufactured, the gas control passage is made by using a sand core mold, which is used to bury the gas in the gas passage when the outer shell is made, and then complete the outer shell. After the production, the sand buried in the position of the gas control passage is removed to form the gas control passage, and when the outer casing is made, it is easy to collapse due to the lack of control of the amount of sand or the strength of the sand core when the sand is buried. The gas control passage is not the same size or can not communicate with the crucible of the cylinder block, so that the production yield is reduced. Therefore, how to reduce the flaw of the gas control passage is an objective of the industry.
