Abstract
Description
本發明是關於一種在縱向上連結兩汽缸的連結元件，以及使用該連結元件的連結型汽缸。 The present invention relates to a coupling member that connects two cylinders in the longitudinal direction, and a coupling type cylinder that uses the coupling member.
在縱向上連結多個汽缸形式的連結型汽缸中，有多位置型汽缸與雙行程汽缸。多位置形汽缸包括設有突出於外部的第一活塞桿的第一汽缸以及設有突接於第一活塞桿的第二活塞桿的第二汽缸。另一方面，雙行程汽缸包括設有突出於外部的第一活塞桿的第一汽缸以及設有突出於外部的第二活塞桿的第二汽缸，且第一活塞桿與第二活塞桿突出於相反的方向。 Among the connected cylinders in the form of a plurality of cylinders connected in the longitudinal direction, there are a multi-position type cylinder and a two-stroke cylinder. The multi-position cylinder includes a first cylinder provided with a first piston rod protruding from the outside and a second cylinder provided with a second piston rod protruding from the first piston rod. In another aspect, the two-stroke cylinder includes a first cylinder provided with a first piston rod protruding from the outside and a second cylinder provided with a second piston rod protruding from the outside, and the first piston rod and the second piston rod protrude from Opposite Direction.
多位置形汽缸能夠藉由第二活塞桿將第一活塞桿的位置決定在中間位置。進一步來說，在多位置型汽缸中，將第二活塞桿的推力施加到第一活塞桿的話，第一活塞桿受到2倍的推力所驅動。當第一活塞桿以2倍的推力驅動時，兩邊的活塞桿能以相同的往復行程來作動。 The multi-position cylinder can determine the position of the first piston rod in an intermediate position by the second piston rod. Further, in the multi-position type cylinder, when the thrust of the second piston rod is applied to the first piston rod, the first piston rod is driven by twice the thrust. When the first piston rod is driven by 2 times the thrust, the piston rods on both sides can be actuated by the same reciprocating stroke.
另一方面，在雙行程汽缸中，各個活塞桿是分別獨立驅動。進一步來說，在此雙行程汽缸中，藉由固定一邊的活塞桿，能夠得到全體而言3段的行程。 On the other hand, in a two-stroke cylinder, each piston rod is independently driven. Further, in this two-stroke cylinder, it is possible to obtain a stroke of three stages in total by fixing one side of the piston rod.

在習知的多位置形汽缸及雙行程汽缸中，安裝孔在軸向上貫通第一汽缸與第二汽缸的汽缸壁。進一步來說，要將螺帽裝設於一邊的汽缸壁的安裝孔，並將與螺帽螺合的螺栓裝設於另一邊的汽缸壁的安裝孔。用以締結兩個汽缸的螺栓分別設於汽缸壁的四個角落。然而，為了連結長的汽缸，不得不在汽缸壁加工來設置長的安裝孔，而無法有效率地製造連結型汽缸。而且，因為螺栓的長度是有限制的，所以無法締結長的汽缸。並且，在活塞徑小的小型連結汽缸中，因為無法在活塞壁朝軸向設置安裝孔的空間，所以要製造小型的連結型汽缸是困難的。 In the conventional multi-position cylinder and the two-stroke cylinder, the mounting hole penetrates the cylinder walls of the first cylinder and the second cylinder in the axial direction. Further, the nut is to be mounted on the mounting hole of the cylinder wall on one side, and the bolt screwed to the nut is attached to the mounting hole of the cylinder wall on the other side. The bolts for concluding the two cylinders are respectively disposed at the four corners of the cylinder wall. However, in order to join long cylinders, it is necessary to machine a long mounting hole in the cylinder wall, and it is not possible to efficiently manufacture the joint type cylinder. Moreover, because the length of the bolt is limited, it is impossible to conclude a long cylinder. Further, in the small-sized connecting cylinder having a small piston diameter, since it is not possible to provide a space in which the mounting hole is provided in the axial direction of the piston wall, it is difficult to manufacture a small connecting type cylinder.

Connecting the discharge port 34a of the pressure chamber 33a and connecting The supply and discharge port 34b of the pressure chamber 33b is provided to the second cylinder 21. When the second piston rod 25 is caused to protrude toward the first piston rod 15, compressed air is supplied to the pressure chamber 33a from the discharge port 34a. At this time, the compressed air in the pressure chamber 33b is discharged from the discharge port 34b. On the other hand, when the second piston rod 25 is moved backward toward the top cover 26b, compressed air is supplied to the pressure chamber 33b from the supply/discharge port 34b. At this time, the compressed air in the pressure chamber 33a is discharged from the discharge port 34a.
各個給排埠為螺孔，以讓連接流體供給部材的接頭螺合也就是螺鎖結合於給排埠，其中流體供給部材由配管、水管等構成。 Each of the supply ports is a screw hole for screwing a joint connecting the fluid supply members, that is, a screw lock, to the discharge port, wherein the fluid supply member is composed of a pipe, a water pipe or the like.
第一活塞12的往復移動的行程比第二活塞22的往復移動的行程來得長的話，能根據第二活塞桿25的前進限位置，設定第一活塞桿15於中間位置。從而，能夠使第一活塞桿15位於第一活塞桿的突出限位置、後退限位置與中間位置等3個位置。能在兩邊的壓力室31a、33a供給相同壓力的壓縮空氣。能在第一活塞12施加第二活塞22的推力。從而，藉由將第一活塞12的往復移動行程與第二活塞22的往復移動行程設為一樣，當第一活塞桿15從後退限位置驅動到突出限位置時，能在第一活塞桿15施加兩倍的推力。 When the stroke of the reciprocating movement of the first piston 12 is longer than the stroke of the reciprocating movement of the second piston 22, the first piston rod 15 can be set at the intermediate position in accordance with the forward limit position of the second piston rod 25. Therefore, the first piston rod 15 can be positioned at three positions such as the projecting limit position, the retreat limit position, and the intermediate position of the first piston rod. Compressed air of the same pressure can be supplied to the pressure chambers 31a, 33a on both sides. The thrust of the second piston 22 can be applied to the first piston 12. Therefore, by setting the reciprocating movement stroke of the first piston 12 to the reciprocating movement stroke of the second piston 22, when the first piston rod 15 is driven from the rear retracting position to the projection limit position, the first piston rod 15 can be Apply twice the thrust.
藉此，在第二活塞桿25透過第一活塞12突接於第一活塞桿15之下，多位置形汽缸10a是連結第一汽缸11與第二汽缸21的連結型汽缸。多位置汽缸10a有決定第一活塞桿15在3個位置的使用型態，也有藉由2倍的推力驅動第一活塞桿15的使用型態。第二汽缸21的前端部21b更能連結未圖示的其他汽缸，而增加第一活塞桿15的停止位置。 Thereby, the second piston rod 25 is protruded below the first piston rod 15 through the first piston 12, and the multi-position cylinder 10a is a joint type cylinder that connects the first cylinder 11 and the second cylinder 21. The multi-position cylinder 10a has a usage pattern that determines the first piston rod 15 at three positions, and also has a usage pattern in which the first piston rod 15 is driven by twice the thrust. The front end portion 21b of the second cylinder 21 is more capable of connecting other cylinders (not shown) to increase the stop position of the first piston rod 15.

The screw holes to which the first screw member 47 is screwed form openings on both surfaces of the upper surface 35a and the lower surface 35b which are parallel to each other in Fig. 2 . Moreover, the discharge ports 32a, 32b are formed with openings in the upper surface 35a. Each of the supply and discharge ports 32a and 32b may be provided at the same position in the width direction with respect to the first screw member 47, and may be shifted. Similarly to the first cylinder 11, the second cylinder 21 has a screw hole through which the second screw member 48 is screwed, and an opening is formed in both the upper surface and the lower surface of the second cylinder 21. Further, openings are formed in the upper surfaces of the second cylinders 21 to the drains 34a, 34b. The sensor groove 36 is provided on the left and right side surfaces 35c, 35d of the first cylinder 11 and the second cylinder 21. A sensor (not shown) for detecting the position of the piston is mounted to the sensor groove 36.
如圖3所示，第一螺絲部材47締結於第一汽缸11，第二螺絲部材48締結於第二汽缸21的話，第一螺絲部材47的前端面中在第一凸緣部41側邊的部分抵壓於第一錐面45。同樣地，第二螺絲部材48的前端面中在第二凸緣部42側邊的部分抵壓於第二錐面46。如此一來，如圖3箭頭所示，第一螺絲部材47的前端面抵壓於第一錐面45的話，第一螺絲部材47會受到在逆時針方向上傾斜的來自第一錐面45的反作用力。藉此，第一汽缸11的連結端部11a的外側部上受到往第二汽缸21方向所施加的抵壓力。此外，第一螺絲部材47的前端部會施加遠離第二凸緣部42的抵壓力到第一凸緣部41。 As shown in FIG. 3, the first screw member 47 is confined to the first cylinder 11, and the second screw member 48 is confined to the second cylinder 21, and the front end surface of the first screw member 47 is on the side of the first flange portion 41. Partially pressed against the first tapered surface 45. Similarly, a portion of the front end surface of the second screw member 48 on the side of the second flange portion 42 is pressed against the second tapered surface 46. As a result, as shown by the arrow in FIG. 3, when the front end surface of the first screw member 47 is pressed against the first tapered surface 45, the first screw member 47 is subjected to the first tapered surface 45 which is inclined in the counterclockwise direction. Reaction force. Thereby, the outer side portion of the connecting end portion 11a of the first cylinder 11 is subjected to the pressing force applied in the direction toward the second cylinder 21. Further, the front end portion of the first screw member 47 applies an abutting force away from the second flange portion 42 to the first flange portion 41.
同樣地，如圖3箭頭所示，第二螺絲部材48的前端面抵壓於第二錐面46的話，第二螺絲部材48會受到在順時針方向上傾斜的來自第二錐面46的反作用力。藉此，第二汽缸21的連結端部21a的外側部上受到往第 一汽缸11方向所施加的抵壓力。此外，第二螺絲部材48的前端部會施加遠離第一凸緣部41的抵壓力到第二凸緣部42。各個螺絲部材47、48的締結力提高的話，前端面接觸錐面45、46的部位的面積增加，且能提高個別的抵壓力。各個錐面45、46的傾斜角雖然設定為大致3~5°，但是10°以上也可以。 Similarly, as shown by the arrow in Fig. 3, if the front end face of the second screw member 48 is pressed against the second tapered surface 46, the second screw member 48 is subjected to the reaction from the second tapered surface 46 which is inclined in the clockwise direction. force. Thereby, the outer portion of the connecting end portion 21a of the second cylinder 21 is subjected to the first The pressing force applied in the direction of one cylinder 11 . Further, the front end portion of the second screw member 48 applies an abutting force away from the first flange portion 41 to the second flange portion 42. When the joining force of each of the screw members 47 and 48 is increased, the area of the portion where the front end surface contacts the tapered surfaces 45 and 46 is increased, and the individual pressing force can be increased. The inclination angle of each of the tapered surfaces 45 and 46 is set to be approximately 3 to 5 degrees, but may be 10 or more.
由連結塊30與各個螺絲部材47、48構成連結元件。藉此，構成連結元件的連結塊30上所設置的兩個錐面45、46互相反向地傾斜。各個螺絲部材47、48締結汽缸11、21的話，螺絲部材47、48對錐面45、46的抵壓力轉換成兩個汽缸11、21的締結力。藉此，藉由各個汽缸11、21在橫向上組裝短尺寸的螺絲部材47、48，2個汽缸11、21能夠堅固地連結。還有，各個螺絲部材47、48的前端面的外周面不接觸凸緣部41、42，而讓前端面抵壓於錐面45、46的構造，能夠將抵壓力轉換成2個汽缸11、21的締結力。 The connecting member 30 and the respective screw members 47 and 48 constitute a connecting member. Thereby, the two tapered faces 45, 46 provided on the coupling block 30 constituting the coupling member are inclined in opposite directions to each other. When the respective screw members 47, 48 are engaged with the cylinders 11, 21, the pressing force of the screw members 47, 48 against the tapered surfaces 45, 46 is converted into the contracting force of the two cylinders 11, 21. Thereby, the short-sized screw members 47 and 48 are assembled in the lateral direction by the respective cylinders 11 and 21, and the two cylinders 11 and 21 can be firmly coupled. Further, the outer peripheral surface of the front end surface of each of the screw members 47 and 48 does not contact the flange portions 41 and 42 and the front end surface is pressed against the tapered surfaces 45 and 46, and the pressing force can be converted into two cylinders 11, The conclusion of 21.

In FIG. 4, the parts common to the parts shown in FIG. 2 are denoted by the same reference numerals.
相較於在圖1與圖2所示的第一汽缸11中設置互相相對的2個第一螺絲部材47，圖4所示的第一汽缸11中設置4個第一螺絲部材47。各個第一螺絲部材47設置於第一汽缸11的四個角落，且以互相相對的2個螺絲部材47共2對。圖4繪示第一汽缸11上設有第一螺絲部材47，第二汽缸21也設有相同數量的第二螺絲部材48。如圖4所示，汽缸4個角落設有螺絲部材的型態，適合用在活塞徑比圖2所示來得大的情況，且汽缸的上下左右尺寸比圖2所示來得大的情況。 In comparison with the two first screw members 47 that are opposed to each other in the first cylinder 11 shown in FIGS. 1 and 2, four first screw members 47 are provided in the first cylinder 11 shown in FIG. Each of the first screw members 47 is provided at four corners of the first cylinder 11 and has two pairs of two screw members 47 opposed to each other. 4 shows that the first cylinder 11 is provided with a first screw member 47, and the second cylinder 21 is also provided with the same number of second screw members 48. As shown in Fig. 4, the four corners of the cylinder are provided with a type of screw member, and it is suitable for the case where the piston diameter is larger than that shown in Fig. 2, and the upper, lower, left and right dimensions of the cylinder are larger than those shown in Fig. 2.
圖5示意連結型汽缸另一實施例的雙行程汽缸10b。在圖5 中，與圖1所示的部材共通的部材用同樣的標號標示。 Fig. 5 illustrates a two-stroke cylinder 10b of another embodiment of a joint type cylinder. In Figure 5 The parts common to the parts shown in Fig. 1 are denoted by the same reference numerals.
如圖5所示，第一汽缸11與第二汽缸21背面對背面相連結。與多位置形汽缸10a同樣地，第一汽缸11的一端部是連結端部11a，另一端部也就是前端部構成突出端部。相對於此，第二汽缸21的一端部是連結端部21a，另一端部也就是前端部21b構成突出端部。藉此，多位置形汽缸10a中，兩邊的汽缸11、21都同樣構成突出端部。 As shown in FIG. 5, the back surfaces of the first cylinder 11 and the second cylinder 21 are coupled to the back surface. Similarly to the multi-position cylinder 10a, one end portion of the first cylinder 11 is a connecting end portion 11a, and the other end portion, that is, a front end portion constitutes a protruding end portion. On the other hand, one end portion of the second cylinder 21 is a connecting end portion 21a, and the other end portion, that is, the front end portion 21b constitutes a protruding end portion. Thereby, in the multi-position cylinder 10a, the cylinders 11 and 21 on both sides also constitute the projecting end portion.
桿蓋16b設置於第二汽缸21的前端部21b。設置於第二活塞22的第二活塞桿25貫通設置於桿蓋16b的貫通孔17b而突出於外部。桿蓋16b藉由卡環18b固定於第二汽缸21。第二汽缸孔23與桿蓋16b之間由密封部材19b所密封。桿蓋16b與第二活塞桿25之間，由密封部材20b所密封。藉此，第一活塞桿15貫通第一汽缸11的桿蓋16a，且第二活塞桿25貫通第二汽缸21的桿蓋16b。 The lever cover 16b is provided at the front end portion 21b of the second cylinder 21. The second piston rod 25 provided in the second piston 22 penetrates through the through hole 17b of the rod cover 16b and protrudes outside. The lever cover 16b is fixed to the second cylinder 21 by a snap ring 18b. The second cylinder bore 23 and the rod cover 16b are sealed by a sealing member 19b. The rod cover 16b and the second piston rod 25 are sealed by the sealing member 20b. Thereby, the first piston rod 15 penetrates the rod cover 16a of the first cylinder 11, and the second piston rod 25 penetrates the rod cover 16b of the second cylinder 21.
如圖5所示，雙行程汽缸10b中，第一汽缸11與第二汽缸21分別藉由基端部也就是連結端部11a、11b來背面對背面相連結。第一活塞桿15從第一汽缸11的前端部11b突出於外部。第二汽缸桿25從第二汽缸21的前端部突出於外部。從而，用以連結2個汽缸11、21的連結塊30還具有作為各個汽缸11、21的頂蓋的功能。在此雙行程汽缸10b中，第一活塞12頂接於連結塊30的話，第一活塞桿15位於後退限，且第一活塞12頂接於桿蓋16a的話，第一活塞桿15位於前進限。而且，第二活塞22頂接於連結塊30的話，第二活塞桿25位於後退限，且第二活塞25頂接於桿蓋16b的話，第二活塞桿25位於前進限。 As shown in Fig. 5, in the two-stroke cylinder 10b, the first cylinder 11 and the second cylinder 21 are connected to the back surface by the base end portions, that is, the joint end portions 11a and 11b, respectively. The first piston rod 15 protrudes from the front end portion 11b of the first cylinder 11 to the outside. The second cylinder rod 25 protrudes from the front end portion of the second cylinder 21 to the outside. Therefore, the joint block 30 for connecting the two cylinders 11 and 21 also functions as a top cover of each of the cylinders 11 and 21. In the two-stroke cylinder 10b, if the first piston 12 is connected to the joint block 30, the first piston rod 15 is located at the backward limit, and if the first piston 12 is abutted against the rod cover 16a, the first piston rod 15 is located at the forward limit. . Moreover, if the second piston 22 is abutted against the joint block 30, the second piston rod 25 is located at the reverse limit, and if the second piston 25 is abutted against the rod cover 16b, the second piston rod 25 is located at the forward limit.
與圖1~圖3所示的情況相同，用以連結2個汽缸11、21的連結 元件由連結塊30、多個第一螺絲部材47與多個第二螺絲部材48所構成。 The connection for connecting the two cylinders 11 and 21 is the same as the case shown in Figs. 1 to 3 . The element is composed of a coupling block 30, a plurality of first screw members 47, and a plurality of second screw members 48.
上述的雙行程汽缸10b，第一活塞桿15與第二活塞桿25能夠個別地獨立驅動。此外，藉由固定兩個活塞桿的一個，另一個的活塞桿能夠以3段的行程來作動。 In the above-described two-stroke cylinder 10b, the first piston rod 15 and the second piston rod 25 can be independently driven independently. In addition, by fixing one of the two piston rods, the other piston rod can be actuated in three strokes.
圖6為當作比較例的習知的多位置形汽缸的縱剖面圖。圖7為當作比較例的習知的雙行程汽缸的縱剖面圖。圖6與圖7所示的習知的例子在前述的非特許文獻1中有記載。在各圖中，與上述部材共通的部材以相同的標號標示。 Fig. 6 is a longitudinal sectional view showing a conventional multi-position cylinder as a comparative example. Fig. 7 is a longitudinal sectional view showing a conventional two-stroke cylinder as a comparative example. The conventional examples shown in Fig. 6 and Fig. 7 are described in the aforementioned non-patent document 1. In the respective drawings, members that are common to the above-described members are denoted by the same reference numerals.
在圖6中所示的習知的多位置形汽缸10c中，第一汽缸11與第二汽缸21的汽缸壁形成在軸向上貫通汽缸壁的安裝孔51、52。為了連結兩邊的汽缸11、21，螺帽53安裝於一邊的汽缸11，與此螺帽螺合的螺栓54則安裝於另一邊的汽缸21。各個安裝孔51、52設置在汽缸11、21的4個角落，藉由4根螺栓來連結汽缸11、21。同樣地，如圖7所示的習知的雙行程汽缸10d中也為了連結兩邊的汽缸11、21，而使用螺帽53與螺栓54。 In the conventional multi-position cylinder 10c shown in FIG. 6, the cylinder walls of the first cylinder 11 and the second cylinder 21 form mounting holes 51, 52 that penetrate the cylinder wall in the axial direction. In order to connect the cylinders 11 and 21 on both sides, the nut 53 is attached to the cylinder 11 on one side, and the bolt 54 screwed to the nut is attached to the cylinder 21 on the other side. The respective mounting holes 51, 52 are provided at four corners of the cylinders 11, 21, and the cylinders 11, 21 are coupled by four bolts. Similarly, in the conventional two-stroke cylinder 10d shown in Fig. 7, the nut 53 and the bolt 54 are used to join the cylinders 11, 21 on both sides.
藉此，使用軸向的螺栓54來連結汽缸11、21的情況中，為了連結長汽缸11、21，不得不在汽缸11、21加工長的安裝孔51、52。因此，無法在汽缸11、21上以高良率與有效率地加工小徑的安裝孔51、52，而難以有效率地製造活塞徑小的小型連結型汽缸。而且，因為螺栓的長度有限，所以無法締結長汽缸。相對於此，使用連結塊30、螺絲部材47、48所構成的連結元件，來連結2個汽缸11、21，而能夠有效率地製造活塞徑小的小型的連結型汽缸。 Thereby, in the case where the cylinders 11 and 21 are coupled by the axial bolts 54, in order to connect the long cylinders 11 and 21, the long mounting holes 51 and 52 have to be processed in the cylinders 11 and 21. Therefore, it is impossible to efficiently process the small-diameter mounting holes 51 and 52 in the cylinders 11 and 21 at a high yield, and it is difficult to efficiently manufacture a small-sized connecting cylinder having a small piston diameter. Moreover, because the length of the bolt is limited, long cylinders cannot be concluded. On the other hand, the two cylinders 11 and 21 are connected by the connecting element formed by the connection block 30 and the screw members 47 and 48, and a small-sized connecting cylinder having a small piston diameter can be efficiently manufactured.
如圖6所示，習知的多位置形汽缸10c中，桿蓋16b安裝於第 二汽缸21的連結端部，止擋件55安裝於第一汽缸11的連結端部。此外，桿蓋16b與止擋件55之間安裝有密封環56。 As shown in FIG. 6, in the conventional multi-position cylinder 10c, the rod cover 16b is mounted on the first The connecting end of the two cylinders 21 and the stopper 55 are attached to the connecting end of the first cylinder 11. Further, a seal ring 56 is mounted between the rod cover 16b and the stopper 55.
如圖7所示，習知的雙行程汽缸10d中，封閉第一汽缸11的汽缸孔13的頂蓋26a安裝於第一汽缸11的連結端部。而且，用以封閉第二汽缸21的汽缸孔23的頂蓋26b安裝於第二汽缸21的連結端部21a。相較於此，使用連結元件的話，連結塊30能夠達到2個頂蓋26a、26b的功能 As shown in FIG. 7, in the conventional two-stroke cylinder 10d, the top cover 26a that closes the cylinder bore 13 of the first cylinder 11 is attached to the joint end of the first cylinder 11. Further, a top cover 26b for closing the cylinder bore 23 of the second cylinder 21 is attached to the joint end portion 21a of the second cylinder 21. In contrast, when the connecting member is used, the connecting block 30 can achieve the functions of the two top covers 26a, 26b.
