Therefore, the current electric hand: the most suitable household hand tools for AC power.

Therefore, pneumatic driving is applied to power hand tools to limit the maximum output due to the compressibility of compressed air, and its component wear is also serious. At present, the pressure of pneumatic hand tools is 5 to 7 bar (bar) for industrial use, so the output of pneumatic hand ear is also limited to 5 to 7 bar.

Moreover, the hydraulic cylinder can also have both cushioning and vibration absorbing effects, which is more helpful for handling. Further, the present invention adopts a gas-liquid hybrid driving method, so that the advantages of high hydraulic output, low weight, and high portability of the pneumatic system can be achieved. The above described features and advantages of the present invention will become more apparent from the following description. [Embodiment] Fig. 1 is a schematic view showing a gas-liquid hybrid driving nail grab according to an embodiment of the present invention. Referring to Figure 1, the gas-liquid hybrid drive pin 100 is adapted to use a compressed gas source 50 as its power source. The gas-liquid mixing drive nail gun 1 includes a pneumatic valve 110, a pneumatic cylinder 120, a hydraulic cylinder 130, a first piston 140, a first piston rod 150, a second piston 16A, and a third The piston 17 〇, the second piston rod 180 and a return element 190. The pneumatic valve 11A has an air inlet 112, wherein the compressed gas source 50 is adapted to be connected to the air inlet 112, and the compressed gas source 50 is, for example, an air compressor for compressing air and compressing it by a pressure difference. Air is sent to the air port 112. The pneumatic cylinder 120 is coupled to the pneumatic valve 11A and has a first chamber 122. The pneumatic cylinder 120 generates a driving force by the gas pressure of the first piston 14 并 and connects a hydraulic cylinder 130 with the first piston rod 150. The hydraulic cylinder 130 has a second chamber 132 and a third chamber 134 communicating with each other. . In the present embodiment, the second chamber 132 is converted into a hydraulic pressure by the driving force of the first piston rod 150 being transmitted by the second piston 160. The first piston 140 directly drives the second piston 160 with the first 1360464 0950102 TW 23785 twf.doc/p piston rod 150. The second piston 160 is closely disposed in the second chamber 132 for use in the second chamber 132. Reciprocating along an axial direction. The third piston 17 is closely disposed in the third chamber 134 for reciprocating in an axial direction within the third chamber 134. The area of the first piston 140 is larger than the second piston 16〇, and the area of the third piston 170 is larger than the second piston 160' and the hydraulic cylinder no is filled with a liquid 136 between the second piston 16〇 and the third piston 170, wherein the liquid 136 can be hydraulic oil, the viscosity of the oil is higher, and the lubricating effect is better. Further, the second piston rod 18 is fixed to the third piston 170 for pushing a nail 60 to be ejected by the third piston no. The returning member 190 is disposed on the second piston rod 180 for generating a relative restoring force to the first piston rod 180 after the second piston rod 180 is subjected to the force of the third piston 17〇. In detail, in the present embodiment, the returning member 190 is, for example, a spring. When the second piston rod 18 is driven by the third piston 170, the returning member 190 is compressed by the second piston rod 180 to be compressed and deformed. And store a resilience. In addition, after the nail 60 is ejected, the return member 190 is restored to its original shape by the restoring force and pushes the second piston rod 180 back to the original position. In detail, when the gas-liquid mixing drive nail 1 (10) of the present embodiment is to be used, the compressed gas source 50 is first used to input the compressed gas, and the air pressure is turned on, 110. Then, the first piston 14 is driven by the gas pressure of the compressed gas source 5, and the second piston 160 is directly driven by the first piston rod 150 while the second piston 16 is pushing the liquid 136. When the liquid 136 is pressed by the second piston 160, the pressure is transferred to the third piston 17〇11 <S > 1360464 0950102TW 23785twf.doc/p. At this time, the second piston rod 18 fixed to the third piston cymbal is pushed by the third piston 170 to eject the nail 60. It is worth mentioning that after the compressed gas source 50 feeds the compressed gas, the cooperation of the pneumatic cylinder 120, the hydraulic cylinder 130, the first piston 150, the second piston 160 and the third piston 170 provides a conversion of the air pressure into the hydraulic pressure. interface. In addition, since the area of the first piston 140 is larger than the second piston 16〇, and the area of the third piston 170 is larger than the second piston 160, the area ratio of the first piston 14〇 to the second piston 160 can be designed, and The area ratio of the three pistons 170 to the second pistons 160 gives an amplified power output. 2 is a partial schematic view of the pneumatic cylinder, the hydraulic cylinder, the first piston, the second piston, and the third piston of FIG. 1. Referring to FIG. 2, when the surface 140a of the first piston 140 is subjected to the force 6 generated by the pressure of the gas, the second piston 160 is directly driven by the first piston rod 丨5, thereby pushing the liquid 136. At the same time, the liquid 136 is pushed by the second piston 16A to drive the second piston 170, which produces a power. According to the Pascal principle, if the liquid 136 in the hydraulic red I% is subjected to a pressure, the pressure p will be transmitted to each part of the liquid 136, and the pressure is constant, that is, the unit area. The same strength. Therefore, Fl=Pa,, n = , F2=Pa.4, where the cadaver α is the gas pressure, 4 is the area of the surface 14〇a of the first piston 14〇, and 乂2 is the surface of the second active 丨6〇 The area of the MOa is the area of the surface 170a of the third piston 170. Moreover, since the area of the surface HOa of the third piston I% is larger than the area of the surface 16 of the second piston 160, the area of the surface l4〇a of the first piston 140 is larger than the surface 160a of the second piston 16〇. The area is, so the power is more than the power π, and produces 12 < S > 1360464 0950102TW 23785twf.doc / p power amplification effect 'power magnification, please refer to the following formula G): λ2 ά 2 In addition, in gas pressure When the first piston 140 is pushed, the power plant is generated; the first piston rod 150 directly transmits the force to the second piston 16〇, and the second piston 160 converts the force into the liquid pressure. The liquid 136 flowing out of the two chambers 132 flows into the third chamber 134 in an equal volume. Due to the area ratio, the stroke of the third piston 17〇 is reduced to the second piston 16 (stroke/for). Times. It is worth noting that since the compressibility of the liquid is much smaller than that of the gas, the output force is not limited by the compressibility of the liquid 136 at high output. In addition, the liquid 136 of the hydraulic cylinder 130 has a buffering and vibration absorbing effect, and has better handling properties for the user. After that, when the nail 60 is fired out of the gas-liquid mixing drive nail gun 1 , the air pressure valve 110 is closed to stop the gas from being applied to the first piston 140, and the recovery element 190 is restored by its restoring force. The original shape, and the second piston rod 180 is returned to the original position. At this time, the third piston 17 is again driven by the second piston rod 180 to push the liquid 136, and the liquid 136 pushes the second piston 160, the first piston rod 150 and the first piston 14 to return to the original position. In particular, the gas pressure source is converted to hydraulic pressure by the incompressibility of the first, second, and third pistons 140, 160, Π0, and liquid of the gas-liquid mixing drive pin. In addition, the principle of Guanka should be used to achieve the effect of power amplification. Compared to the conventional pneumatic hand tools, under the same gas pressure, no additional power source is required, and the gas-liquid hybrid drive nail can be used to achieve a larger output. 13 (S > 1360464 0950102TW 23785twf.doc/p
請繼續參考圖1，為了讓氣-液混合驅動釘槍100能夠 持續地使用，第一活塞140及第二活塞160的位置與行程 範圍可適當地限制。舉例而言，為了避免第二活塞140移 動範圍過大’而造成液壓缸130之液體136溢漏並進而使 氣-液混合驅動訂搶100失效，液壓叙130更可具有一第三 限位部139。第三限位部139連接於第三腔室134相對於 第二腔室132之一側，其用以限位第三活塞17〇之轴向移 動範圍。詳細來說’當氣壓閥110開啟時，第三活塞17〇 受到液體136與第一活基160的帶動而移動時，第三活塞 170至多移動至承靠於第三限位部139。由於液體136的不 可壓縮性，因此第二活塞160在第三活塞17〇承靠於第三 限位部139之後並不會繼續推進，所以第二活塞16〇不會 落入第三腔室134中。 此外，本實施例之液壓缸130還可具有一第二限位部 138，其位於第二腔室132相對於第三腔室134之一側，並With continued reference to Fig. 1, in order to allow the gas-liquid hybrid drive nail gun 100 to be used continuously, the position and stroke range of the first piston 140 and the second piston 160 can be appropriately limited. For example, in order to prevent the second piston 140 from moving too large, the liquid 136 of the hydraulic cylinder 130 overflows and the gas-liquid hybrid drive staple 100 is invalidated. The hydraulic pressure 130 may further have a third limiting portion 139. . The third limiting portion 139 is connected to one side of the third chamber 134 with respect to the second chamber 132 for limiting the axial movement range of the third piston 17A. In detail, when the third piston 17 is moved by the liquid 136 and the first movable base 160 when the pneumatic valve 110 is opened, the third piston 170 is moved to the third stopper 139 at most. Due to the incompressibility of the liquid 136, the second piston 160 does not continue to advance after the third piston 17 is supported by the third limiting portion 139, so the second piston 16 does not fall into the third chamber 134. in. In addition, the hydraulic cylinder 130 of the present embodiment may further have a second limiting portion 138 located on one side of the second chamber 132 relative to the third chamber 134, and

In detail, when the nail 60 is ejected, the second piston 17Q is urged by the splicing element and the second piston (10) to push the liquid 136. Then, when the liquid 136 is pushed again, when the piston 160 moves, 篦-, 、, 堂, (part m - 丄: the base 160 at most bears against the second limit °. Hunting by the second limiting portion 138, Limiting the moving distance of the liquid 136, the first active tube 170 and the second piston rod 160. The first first active electron step 'in the present embodiment' is a pressure sensor 110, for example, the sensor 280 is lightly connected to the single wafer controller 270. It is used to feed the sensed force to the single-chip controller 270 for 1360464 0950102TW 23785twf.doc/p '. The single-chip control is crying 270.

In another embodiment not shown, the control system of the pneumatic valve 11 亦可 can also be designed as The accumulator 290 is coupled between the first chamber 122 and the air pressure valve 11 to absorb the reaction force generated after the nail 60 is hit, or the absorbed pressure is hit by the next nail 60. Released to achieve energy saving purposes. In detail, the accumulator 290 can include a body 292, a spring 294 and a first The fourth piston 296. The fourth piston 296 is closely disposed in the body 292' and the spring 294 is connected between the body 292 and the fourth piston 296. When the nail is struck, the reaction force is returned, and the fourth piston 296 is passed. The pushing spring 294' causes the spring 294 to compress and deform, thereby achieving the effect of accumulating pressure and energy recovery. When the pressure of the compressed gas is too small, the fourth piston 296 is pushed by the elastic restoring force of the spring 294, and pressurized to the compressed gas, In order to increase the output of the gas. • In particular, the 'force sensor 280 can sense the power of the second piston rod 180' and return the sensed power to the single-chip controller 270°. The wafer controller 270 can control the amount of gas output of the gas pressure valve 11 by the result sensed by the force sensor 280.
