Description
本創作係有關於一種緩衝裝置，尤指一種應用於往復式氣動工具緩衝減震用之氣動工具氣缸緩衝裝置。The present invention relates to a cushioning device, and more particularly to a pneumatic tool cylinder cushioning device for cushioning and damping of a reciprocating pneumatic tool.
按，往復式氣動工具係一種利用高壓空氣作為工作動力源的手工具，習知往復式氣動工具，如第九圖所示，包含：一握柄10、一氣閥單元20、一氣缸30、一活塞件40，其中該握柄10設有一供接設高壓空氣的進氣端101、一與該進氣端101相通之進氣通道102、一控制該進氣端101進氣之開關(圖中未示)及一筒狀部103，該筒狀部103內具有一沿軸向設置之腔室104，該腔室104與該進氣通道102相通，該氣閥單元20係設置於該筒狀部之腔室104內端部，該氣缸30一端穿入該筒狀部103之腔室104內結合固定，使該氣缸30與該氣閥單元20貼靠，該氣缸30內部設有一沿軸向設置之滑室301，另該氣缸30壁內於滑室301前端與氣閥單元20間設有一空氣流道302，藉由該空氣流道302使滑室301前端與氣閥單元20連通，該活塞件40容置於該氣缸30之滑室301內活動前後滑移。藉此，使用時開啟握柄10上的開關，使高壓空氣由握柄10之進氣端101經過進氣通道102到達筒狀部103腔室104內端部的氣閥單元20，透過該氣閥單元20控制高壓空氣由氣缸30之滑室301後端進入，推動活塞件40往前滑動位移至預定位置撞擊工 具頭(圖中未示)，受該工具頭擋止而停止滑動，接著高壓空氣經氣閥單元20控制變換由空氣流道302進入氣缸30滑室301前端，推動活塞件40往後滑動位移撞擊氣閥單元20，受該氣閥單元20擋止而停止滑動，如此，往復前後推動活塞件40，進行預定的工作。According to the reciprocating pneumatic tool, a hand tool using high-pressure air as a working power source, the conventional reciprocating pneumatic tool, as shown in the ninth figure, comprises: a handle 10, a gas valve unit 20, a cylinder 30, and a The piston member 40, wherein the handle 10 is provided with an intake end 101 for connecting high-pressure air, an intake passage 102 communicating with the intake end 101, and a switch for controlling the intake of the intake end 101 (in the figure) And a cylindrical portion 103 having an axially disposed chamber 104 therein, the chamber 104 communicating with the intake passage 102, the valve unit 20 being disposed in the tubular shape At the inner end of the chamber 104, one end of the cylinder 30 penetrates into the chamber 104 of the cylindrical portion 103, and the cylinder 30 is abutted against the valve unit 20, and the cylinder 30 is internally provided with an axial direction. a sliding chamber 301 is disposed, and an air flow passage 302 is disposed between the front end of the sliding chamber 301 and the gas valve unit 20 in the wall of the cylinder 30. The air flow passage 302 connects the front end of the sliding chamber 301 with the gas valve unit 20. The piston member 40 is accommodated in the sliding chamber 301 of the cylinder 30 to move back and forth. Thereby, the switch on the handle 10 is opened during use, so that the high-pressure air passes through the intake passage 101 of the grip 10 through the intake passage 102 to the valve unit 20 at the inner end of the chamber 104 of the cylindrical portion 103, through which the gas passes. The valve unit 20 controls the high pressure air to enter from the rear end of the sliding chamber 301 of the cylinder 30, and pushes the piston member 40 to slide forward to a predetermined position. The head (not shown) is stopped by the tool head to stop sliding, and then the high-pressure air is controlled by the gas valve unit 20 to enter the front end of the cylinder 30 of the cylinder 30 by the air flow passage 302, and the piston member 40 is pushed and displaced rearward. The impingement valve unit 20 is stopped by the valve unit 20 to stop sliding, so that the piston member 40 is pushed back and forth before and after the reciprocation to perform a predetermined operation.
然該習知氣動工具，推動活塞件40往後滑動位移撞擊氣閥單元20時，會產生反作用力傳遞至使用者手部，如此，在活塞件40不斷的往復前後滑動位移過程中，不僅使用者需費更大的力氣握持該氣動工具，並且容易有手痠不舒服的情況，甚至會對使用者手部關節造成傷害。However, when the conventional pneumatic tool pushes the piston member 40 to slide back and collide against the valve unit 20, a reaction force is transmitted to the user's hand. Thus, during the sliding movement of the piston member 40, the sliding member is not only used. It takes a lot of effort to hold the pneumatic tool, and it is easy to have unsatisfactory hands and even cause damage to the user's hand joints.
為改善上述缺失，乃有業者開發出於筒狀部之腔室內設置一圓柱形軟性墊塊或一彈簧，藉由該軟性墊塊或彈簧於活塞件40往後滑動位移撞擊氣閥單元20時，達到緩衝減震效果，降低反作用力傳遞至使用者手部。惟，該軟性墊塊及彈簧均僅係利用本身的彈性來達到緩衝作用，如此的緩衝減震效果不佳，且軟性墊塊及彈簧在高頻率的反覆使用之下，便易產生彈性疲乏，降低緩衝之效果，以致需時常更換該軟性墊或彈簧，使用成本提高。In order to improve the above-mentioned deficiency, a manufacturer has developed a cylindrical soft spacer or a spring in the chamber of the cylindrical portion, and the soft spacer or spring slides rearwardly against the valve member 20 when the piston member 40 is slidably displaced. , to achieve the buffer damping effect, reduce the reaction force to the user's hand. However, the soft pad and the spring only use the elasticity of the body to achieve the buffering effect, such cushioning and shock absorption effect is not good, and the soft pad and the spring are easy to produce elastic fatigue under the repeated use of the high frequency. Reduce the effect of the buffer, so that the soft pad or spring needs to be replaced frequently, and the use cost is increased.
本創作人有鑑於習知氣動工具，於筒狀部之腔室內設置一軟性墊塊或一彈簧，所產生的緩衝減震效果不佳，且軟性墊塊及彈簧易產生彈性疲乏，而需定期更換，使用成本增加，是以乃思及創作的意念，經多方探討設計與試作樣品試驗，及多次修正改良後，終設計出本創作。In view of the conventional pneumatic tools, the creator has a soft pad or a spring in the chamber of the tubular portion, which produces a cushioning damping effect, and the soft pad and the spring are prone to elastic fatigue, and need to be periodically Replacement, the increase in the cost of use, is based on the idea of creation and creation, after many discussions on design and trial sample test, and many corrections and improvements, the final design of this creation.
