Description
本發明係關於具備檢測行程終端功能之流體壓缸裝置。 The present invention relates to a fluid pressure cylinder device having a function of detecting stroke end.
流體壓缸具備檢測活塞構件的前進行程終端及後退行程終端的行程終端檢測功能的各種流體壓缸裝置業已實用化。特別是壓鑄機或射出成形機中用以驅動芯模的油壓缸中,在缸本體中配備有組裝行程終端檢測手段的情況很多。 Various fluid pressure cylinder devices having a stroke end detection function for detecting forward stroke end and backward stroke end of a piston member have been put into practical use. In particular, in a hydraulic cylinder for driving a core mold in a die casting machine or an injection molding machine, a cylinder body is often equipped with an assembly stroke end detection means.
專利文獻1所載的具備檢測行程終端功能之壓缸裝置中,活塞構件的中心部形成有從缸頭側端面延伸至活塞桿內的插入孔,而機構室形成構件的嵌裝部係藉由螺合而固定在缸本體的缸頭側端壁的中央部的裝設孔,且將非磁性體製的保護管插入於插入孔,並使其基端部固定於機構室形成構件。 In the cylinder device with a stroke end detection function described in Patent Document 1, an insertion hole extending from the cylinder head side end face into the piston rod is formed in the center of the piston member, and the fitting portion of the mechanism chamber forming member is formed by It is screwed and fixed to the installation hole in the center of the cylinder head side end wall of the cylinder body, and a protective tube of a non-magnetic system is inserted into the insertion hole, and its base end portion is fixed to the mechanism chamber forming member.
2條非磁性體製之細的第1、第2管體插入保護管內,第1、第2管體的基端部則保持於機構室形成構件,且第1、第2管體支持成懸臂狀態。第1管體中裝設有檢測前進行程終端的第1簧片開關與連接於該開關的第1線束,第2管體則裝設有檢測後退行程終端的第2簧片開關與連接於該開關的第2線束。 The first and second tube bodies of two non-magnetic systems are inserted into the protective tube, and the base ends of the first and second tube bodies are held in the mechanism chamber forming member, and the first and second tube bodies are supported as cantilevers. status. The first tube body is provided with a first reed switch for detecting the forward stroke terminal and a first wiring harness connected to the switch, and the second tube body is provided with a second reed switch for detecting the backward stroke terminal and connected to the first 2nd harness for switch.
因第1、第2管體是口徑非常小的元件,故第1、第2管體內未封入有樹脂封閉材。 Since the first and second tube bodies are very small-diameter components, no resin sealing material is sealed in the first and second tube bodies.
插入孔基端部的外周側裝設有用以使第1、第2簧片開關行ON/OFF動作的環狀永久磁鐵。而且,機構室形成構件中組裝有可分別調節第1、第2管體之軸心方向之位置的第1、第2位置調節機構。 A ring-shaped permanent magnet for turning ON and OFF the first and second reed switch rows is mounted on the outer peripheral side of the base end of the insertion hole. In addition, first and second position adjustment mechanisms capable of adjusting positions in the axial center direction of the first and second pipe bodies, respectively, are incorporated in the mechanism chamber forming member.
[專利文獻1]日本專利第3280345號公報 [Patent Document 1] Japanese Patent No. 3280345
該專利文獻1揭示的具備檢測行程終端功能的壓缸裝置中,因為是將保護管插入活塞構件的插入孔,且將該保護管插入第1、第2管體的構造,所以不得不採用口徑非常小且管壁薄的管體作為第1、第2管體。 In the cylinder device with a stroke end detection function disclosed in Patent Document 1, a protective tube is inserted into the insertion hole of the piston member, and the protective tube is inserted into the first and second tube bodies. Therefore, the caliber has to be adopted. A very small and thin pipe body is used as the first and second pipe bodies.
因而,無法將第1、第2簧片開關與第1、第2線束以樹脂封閉在第1、第2管體內。因此,第1、第2管體的剛性較低,在較大的衝擊反覆作用在壓缸裝置時,有第1、第2管體容易振動,而致連接在第1、第2線束與第1、第2簧片開關的連接部發生斷線、或第1、第2簧片開關的位置變動而使行程終端檢測精確度降低的問題。 Therefore, the first and second reed switches and the first and second wire harnesses cannot be enclosed in the first and second tubes with resin. Therefore, the rigidity of the first and second pipe bodies is low. When a large impact is repeatedly applied to the cylinder device, the first and second pipe bodies are easy to vibrate, and the first and second wire harnesses are connected to the first and second wire harnesses. 1. The connection part of the second reed switch is disconnected, or the position of the first and second reed switches is changed, which reduces the detection accuracy of the stroke end.

接著,說明有關上束說明之具備有檢測行程終端功能之油壓缸裝置1的作用與功效。 Next, the functions and effects of the hydraulic cylinder device 1 provided with the end-of-stroke detection function described above will be described.
在活塞構件4到達前進行程終端(前進極限位置)時,藉第1位置調節機構32預先設定第1管體24的左右方向位置,以使環狀永久磁鐵31面對第1簧片開關26。在此情況中,在使鎖定第1操作構件32s的鎖定螺帽32n鬆開的狀態下,將第1操作構件32s往右螺旋方向轉動時,可使第1管體24和第1可動構件32a一起向右方調節位置,若向其相反方向轉動,則可將第1管體24向左方調節位置。在該調節後,將鎖定螺帽32n鎖緊。 When the piston member 4 reaches the forward stroke end (forward limit position), the left-right position of the first tube body 24 is set in advance by the first position adjustment mechanism 32 so that the ring-shaped permanent magnet 31 faces the first reed switch 26. In this case, when the lock nut 32n that locks the first operation member 32s is released, the first operation member 32s is rotated in the right spiral direction, so that the first pipe body 24 and the first movable member 32a can be made. Adjust the position to the right together. If you turn it in the opposite direction, you can adjust the position of the first tube 24 to the left. After this adjustment, the lock nut 32n is locked.
再者,在活塞構件4到達後退行程終端(後退極限位置)時,藉第2位置調節機構33預先設定第2管體25的左 右方向位置,以使環狀永久磁鐵31面對第2簧片開關27。在此情況中,可藉由和上述相同方式操作第2操作構件33s,以調節第2管體25的位置。 In addition, when the piston member 4 reaches the end of the backward stroke (backward limit position), the second position adjustment mechanism 33 is used to set the left side of the second tube 25 in advance. Position it in the right direction so that the ring-shaped permanent magnet 31 faces the second reed switch 27. In this case, the position of the second pipe body 25 can be adjusted by operating the second operation member 33s in the same manner as described above.
因而,油壓缸裝置1在運作狀態時,若活塞構件4到達前進行程終端時,第1簧片開關26的ON/OFF狀態會被切換;同樣的,若活塞構件4到達後退行程終端時,則第2簧片開關27的ON/OFF狀態會被切換,故可確實檢測油壓缸2的前進行程終端和後退行程終端。 Therefore, when the hydraulic cylinder device 1 is in the operating state, when the piston member 4 reaches the end of the forward stroke, the ON / OFF state of the first reed switch 26 is switched; similarly, when the piston member 4 reaches the end of the backward stroke, Since the ON / OFF state of the second reed switch 27 is switched, the forward stroke end and the backward stroke end of the hydraulic cylinder 2 can be reliably detected.
因為是構成第1、第2管體24、25直接插入形成在活塞構件4的插入孔21內的結構,故可將第1、第2管體24、25的直徑加大。因此,可將第1、第2樹脂封閉構件29、30分別充填在第1、第2管體24、25的內部,藉以將第1、第2簧片開關26、27及第1、第2線束實施樹脂封閉。 Since the first and second pipe bodies 24 and 25 are directly inserted into the insertion hole 21 formed in the piston member 4, the diameters of the first and second pipe bodies 24 and 25 can be increased. Therefore, the first and second resin sealing members 29 and 30 can be filled into the first and second pipe bodies 24 and 25, respectively, so that the first and second reed switches 26 and 27 and the first and second reed switches 26 and 27 can be filled. The wiring harness is sealed with resin.
結果,第1、第2管體24、25的剛性得以提高,第1、第2管體24、25較不易振動,第1、第2簧片開關26、27與第1、第2線束26a、27a的連接部不會發生斷線,第1、第2簧片開關26、27的位置也不會變動,可提高行程終端檢測精確度。因而,得以實現具有耐久性及可靠性均優異之具備檢測行程終端功能的油壓缸裝置1。而且,因為省略了習知技術中所採用的保護管,製作費也可降低。 As a result, the rigidity of the first and second pipe bodies 24 and 25 is improved, the first and second pipe bodies 24 and 25 are less likely to vibrate, and the first and second reed switches 26 and 27 and the first and second wire harnesses 26a No disconnection will occur at the connection parts of 27a and 27a, and the positions of the first and second reed switches 26 and 27 will not change, which can improve the accuracy of stroke end detection. Therefore, the hydraulic cylinder device 1 having the end-of-stroke detection function having excellent durability and reliability can be realized. Moreover, since the protective tube used in the conventional technology is omitted, the manufacturing cost can be reduced.
此外,因為設有第1、第2位置調節機構32、33,故第1、第2管體24、25的軸心方向的位置可加以調節。 In addition, since the first and second position adjustment mechanisms 32 and 33 are provided, the positions in the axial center direction of the first and second pipe bodies 24 and 25 can be adjusted.
因設有分別封鎖第1、第2管體24、25前端部的第1、第2封鎖構件34、35,故可防止油壓從第1、第2管體24、25的前端向第1、第2管體24、25內滲入。 Since the first and second blocking members 34 and 35 are provided to block the front ends of the first and second pipe bodies 24 and 25, respectively, the oil pressure can be prevented from going from the front ends of the first and second pipe bodies 24 and 25 to the first. 2. The second tube bodies 24 and 25 penetrate.
