本新型關於一缸體結構，尤其是關於一種可以增進進程速度之油壓缸或氣壓缸的缸體結構。The present invention relates to a cylinder structure, and more particularly to a cylinder structure of a hydraulic cylinder or a pneumatic cylinder which can increase the speed of the process.
按氣壓缸或油壓缸係分別以氣體或油液為介質，推動活塞及其活塞桿前進或回縮，使得氣體或油液的壓力可以經由氣壓缸或油壓缸轉換成機械能，並帶動活塞桿外端部所連結的機構。Pressing the gas cylinder or the hydraulic cylinder system as the medium to push the piston and its piston rod forward or retract, respectively, so that the pressure of the gas or oil can be converted into mechanical energy through the pneumatic cylinder or the hydraulic cylinder, and is driven. The mechanism to which the outer end of the piston rod is connected.
氣壓缸或油壓缸其所使用的推動介質不同，其一為氣體，另一為油液，而兩者的缸體結構則相同。第1圖是繪示習知一般氣壓缸或油壓缸的剖面示意圖。請參閱第1圖所示，一般氣壓缸或油壓缸主要包括一缸筒單元910、一活塞920與一活塞桿930。缸筒單元910具有一缸筒911與位於其兩端部的一第一端座912與一第二端座913，其中第一端座912設有一穿口914；兩端座912、913分別設有一第一接口915與一第二接口916為與缸筒911內部的缸室917相通。活塞920容置於缸筒的缸室917，缸室916以活塞920為界，而於活塞920與第一端座912之 間形成一回程缸室918，以及於活塞920與第二端座913之間形成一進程缸室919。活塞桿930容置於回程缸室918，活塞桿930的內端部結合於活塞920，而外端部則經由第一端座912的穿口914伸出於第一端座912，可供連結一外部機構(未圖示)。Pneumatic or hydraulic cylinders use different propelling media, one for gas and the other for oil, and the cylinder structure of the two is the same. Fig. 1 is a schematic cross-sectional view showing a conventional pneumatic cylinder or hydraulic cylinder. Referring to FIG. 1 , a general pneumatic cylinder or a hydraulic cylinder mainly includes a cylinder unit 910 , a piston 920 and a piston rod 930 . The cylinder unit 910 has a cylinder 911 and a first end seat 912 and a second end seat 913 at the two ends thereof. The first end seat 912 is provided with a through hole 914; the two end seats 912 and 913 are respectively provided. A first interface 915 and a second interface 916 are in communication with the cylinder chamber 917 inside the cylinder 911. The piston 920 is housed in a cylinder chamber 917 of the cylinder, and the cylinder chamber 916 is bounded by the piston 920, and the piston 920 and the first end seat 912 A return cylinder chamber 918 is formed therebetween, and a process cylinder chamber 919 is formed between the piston 920 and the second end seat 913. The piston rod 930 is received in the return cylinder chamber 918. The inner end of the piston rod 930 is coupled to the piston 920, and the outer end portion is extended to the first end seat 912 via the opening 914 of the first end seat 912 for connection. An external mechanism (not shown).
活塞桿930於進程動作時，介質(氣體或油液，未圖示)由第二端座913的第二接口916注入於進程缸室919，介質逐漸充滿於進程缸室919而逐漸將活塞920及其活塞桿930往第一端座912的方向推進，使得活塞桿930外端部所連結的外部機構產生相對應的推進動作。相反地，活塞桿930於回程動作時，介質由第一端座912的第一接口915注入於回程缸室919，介質逐漸充滿於回程缸室918而逐漸將活塞920及其活塞桿930往第二端座913的方向推動而回縮，使得活塞桿930外端部所連結的外部機構產生相對應的回縮動作。When the piston rod 930 is in the process, a medium (gas or oil, not shown) is injected into the process cylinder chamber 919 by the second port 916 of the second end seat 913, and the medium gradually fills the process cylinder chamber 919 and gradually the piston 920. The piston rod 930 is advanced in the direction of the first end seat 912 such that the external mechanism coupled to the outer end of the piston rod 930 produces a corresponding propulsion action. Conversely, when the piston rod 930 is in the return stroke, the medium is injected into the return cylinder chamber 919 by the first interface 915 of the first end seat 912, and the medium gradually fills the return cylinder chamber 918 to gradually move the piston 920 and its piston rod 930 toward the first stage. The direction of the two end seats 913 is pushed and retracted, so that the external mechanism connected to the outer end of the piston rod 930 produces a corresponding retracting action.
在進程動作時，氣壓缸或油壓缸於其活塞920及其活塞桿930逐漸往前(第一端座912的方向)推進時，其進程缸室919亦逐漸增大，而介質必須完全注滿於進程缸室919，才能將活塞920往前推進至第一端座912。亦即，介質注滿於進程缸室919的速度將會影響活塞920及其活塞桿930的推進速度。When the process moves, the pneumatic cylinder or the hydraulic cylinder gradually advances as its piston 920 and its piston rod 930 move forward (in the direction of the first end seat 912), and the process cylinder chamber 919 also gradually increases, and the medium must be completely injected. Full of the process cylinder chamber 919, the piston 920 can be advanced forward to the first end seat 912. That is, the speed at which the media is filled in the process cylinder chamber 919 will affect the advancement speed of the piston 920 and its piston rod 930.
而習知氣壓缸或油壓缸，其進程缸室919係呈完全空曠的空間，其在進程動作時，要將氣體或油液等介質完全注滿於逐漸增大且完全空曠的進程缸室919時，其 所花費的注氣(注入氣體)或注油(注入油液)的時間較長，亦即，減緩活塞920及其活塞桿930的推進速度。In the conventional pneumatic cylinder or hydraulic cylinder, the process cylinder chamber 919 is completely empty, and during the process, the medium such as gas or oil is completely filled with the progressively enlarged and completely empty process cylinder chamber. At 919, its The time required for gas injection (injection of gas) or oil injection (injection of oil) is long, that is, the speed of advancement of the piston 920 and its piston rod 930 is slowed down.

The 200 and its piston rod 300 are pushed toward the second end seat 130 to be retracted, so that the external mechanism to which the outer end portion 320 of the piston rod 300 is coupled generates a corresponding retracting action.
