Description
本發明是關於一種夾頭，特別是指一種利用氣體來控制夾座動作之可提升穩定性的氣動夾頭。BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a collet, and more particularly to a pneumatic collet that utilizes gas to control the clamping action to improve stability.
以往氣動夾頭為了達到固定一個加工物件的目的，通常包含一個基座、一支安裝在該基座上的滑軌，以及兩個可相對移動的架設在該滑軌上的夾座，該氣動夾頭還包含一個利用氣體來帶動該等夾座移近及分開的氣動機構。習知氣動夾頭利用單支滑軌來導引該等夾座移動的設計，雖然可以達到固定加工物件的目的，但是該等夾座如果要移動順暢，必需和該滑軌間精確的配合，亦即，以往氣動夾頭對於元件精度的要求相當高，不容許產生些微的公差，此項結構的限制，不僅製造成本高。相反的，如果元件在加工及組裝時產生些微的偏差時，該等夾座就無法穩定的移動。In the past, in order to achieve the purpose of fixing a workpiece, a pneumatic chuck usually comprises a base, a slide rail mounted on the base, and two relatively movable clamps mounted on the slide rail. The collet also includes a pneumatic mechanism that utilizes gas to drive the clips closer and apart. Conventional pneumatic chucks use a single slide rail to guide the design of the movement of the clamps. Although the purpose of fixed workpieces can be achieved, if the clamps are to move smoothly, it is necessary to accurately match the slide rails. That is, in the past, the pneumatic chuck has a relatively high requirement for component accuracy, and does not allow slight tolerances. The limitation of this structure is not only high in manufacturing cost. Conversely, if the components are slightly offset during processing and assembly, the clips cannot move stably.
另一方面，習知單軌式氣動夾頭通常是在每個夾座上設置兩個平行間隔的側壁，以及一個介於該等側壁之間並供該滑軌穿過的導槽，該氣動夾頭還具有兩排分別夾設在其中一個側壁與該滑軌之間的滾珠。而依一般力學原理，在承受相同扭矩的情況下，位在該滑軌相反側之所述滾珠之間的距離越大，該等滾珠的受力越小。但習知單軌式氣動夾頭之每個滾珠，不僅與相對應之該夾座及該滑軌之間只能以點接觸，荷重較小，位在該滑軌相反側之所述滾珠之間的距離也比較小，故受力比較大。On the other hand, conventional monorail pneumatic chucks are usually provided with two parallel spaced side walls on each of the holders, and a guide groove between the side walls for the passage of the slide rails, the pneumatic clamp The head also has two rows of balls sandwiched between one of the side walls and the slide rail. According to the general mechanical principle, the greater the distance between the balls on the opposite side of the slide rail, the smaller the force of the balls, under the same torque. However, each ball of the conventional monorail type pneumatic chuck has only a point contact with the corresponding holder and the slide rail, and the load is small, and is located between the balls on the opposite side of the slide rail. The distance is also relatively small, so the force is relatively large.
本發明的目的是在提供一種能夠克服先前技術的至少一個缺點的可提升穩定性的氣動夾頭。It is an object of the present invention to provide a pneumatic chuck that provides improved stability that overcomes at least one of the disadvantages of the prior art.

本發明有益的功效在於：利用該第一滑軌及該第二滑軌來共同夾持該等夾座，以及該第一滑軌及該第二滑軌之間距離可調整的設計，可以精確的調整出適合夾持該等夾座的距離，藉此降低元件在加工時產生的些微偏差，對於該等夾座移動穩定性的影響。The beneficial effect of the present invention is that the first sliding rail and the second sliding rail are used to jointly clamp the clamping seats, and the adjustable distance between the first sliding rail and the second sliding rail can be accurately adjusted.

The structure of the clamp holder 42 can expand the distance between the friction reducing members 43 on the opposite side of the holder 42 under the same torque, due to the difference between the friction reducing members 43 on the opposite side. The greater the distance, the smaller the force of the friction reducing element 43 under the condition of the bending moment, so that the aforementioned structure can also extend the service life of the grinding reducing elements 43.

At 335, after the pneumatic chuck is installed, if there is a space in front of the end seat surface 112 of the first end seat 11, the gas output source can overlap the clamping air inlet passage 33 and the open clamp. The first inlet 334 of the inlet passage 33' is closed and the second inlet 335 is closed. If there is no space in front of the end seat surface 112 of the first end seat 11 after installation, the gas output source may be overlapped between the clamping intake passage 33 and the second of the open clamp intake passage 33'. The inlet 335 is closed and the first inlet 334 is closed, thereby improving the ease of assembly.
當該氣體輸出源銜接在該夾持進氣通道33及該開夾進氣通道33’上後，如果氣體由該夾持進氣通道33進入時，氣體將如圖7箭頭所示，分別經由該等活塞通道154的所述夾持進氣端155進入，藉由氣體推送位於該等活塞通道154內的所述活塞31，就可以帶動該等夾座42往一個固定方向移動，並固定該加工物件(圖未示)，相反的，如果氣體由該開夾進氣通道33’進入，將如圖6箭頭所示，將帶動該等夾座42往相反於該固定方向的一個釋放方向移動，如此一來，就可以達到以氣體帶動該等夾座42固定及釋放該加工物件的目的。When the gas output source is coupled to the clamped intake passage 33 and the open clamp intake passage 33', if gas enters through the clamped intake passage 33, the gas will be respectively indicated via arrows as shown in FIG. The clamping inlet end 155 of the piston passage 154 enters, and the piston 31 is driven by the gas in the piston passage 154 to move the clamping seat 42 in a fixed direction and fix the Processing the object (not shown), conversely, if the gas enters through the open clamp inlet passage 33', as shown by the arrow in Fig. 6, the clamp holder 42 will be moved to a release direction opposite to the fixed direction. In this way, the purpose of driving the clips 42 to fix and release the processed objects by gas can be achieved.
由以上說明可知，本發明利用間隔設置的該第一滑軌21及該第二滑軌22來夾持該等夾座42，以及在兩者間設置滾柱形式的該等減磨元件43的結構不僅新穎，更可藉由調整該第二滑軌22，使該等夾座42更精確的架設在該第一滑軌21及該第二滑軌22之間。前述結構的配合，除了可以降低對元件加工精度的要求，以提高製造的方便性外，亦可提高元件作動的順暢性。此外，本發明在該夾持進氣通道33及該開夾進氣通道33’上設置彼此垂直的所述第一入口334及所述該第二入口335，也可以提高該氣動夾頭在安裝時的方便性，故本發明確實是一個結構新穎、實用的產品。As can be seen from the above description, the present invention utilizes the first slide rail 21 and the second slide rail 22 which are spaced apart to clamp the clamps 42 and the friction reducing elements 43 in the form of rollers. The structure is not only novel, but also the second sliding rail 22 is adjusted to make the clamping seat 42 more accurately between the first sliding rail 21 and the second sliding rail 22. The cooperation of the foregoing structure can not only reduce the requirement for processing precision of components, but also improve the convenience of manufacture, and can also improve the smoothness of component actuation. In addition, the present invention provides the first inlet 334 and the second inlet 335 perpendicular to each other on the clamping air inlet passage 33 and the opening air inlet passage 33', and the pneumatic chuck can be improved in installation. The convenience of the time, the present invention is indeed a novel and practical product.
惟以上所述者，僅為本發明的實施例而已，當不能以此限定本發明實施的範圍，凡是依本發明申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本發明專利涵蓋的範圍內。However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
