Description of the invention: [Technical field to which the invention pertains] and particularly relates to a gas. The present invention relates to a nail gun that is driven by a nail and a liquid mixture. [Prior Art] Γ 备 Preparation and mechanical, water and electricity equipment can be divided into non-powered and power hand tools roughly including electric hand tools, pneumatic hand-type hand tools, pressure hand tools and so on. - Powerful hand-fired ί Different considerations. The description is made with the same handguards that may have different driving modes for the power output. The electric hand main production ^ has electric drill, Wei, electric shear, heavy, does not meet the requirements of hand tools ^^ and it is easy to rut Acquired, so the current source of Lei Xu is the parent flow power, the most home hand tools. Hands-on tools are suitable for small output. The frequency of use is not high. ^)) = The main products of the tool are air drill, pneumatic wrench, gas _ sub 'pneumatic polishing machine, pneumatic grinder high, that is, the same wheel single = quantity can be output Compared with the electric motor system, the power is lower than the electric motor system. The pneumatic drive system is driven by the electric motor and weighs I. At the same time, because the portable small electric compressor is equivalent to 200904600 0950102TW 23785twf.doc/p popularization, the pneumatic hand tool is suitable for no. Professional applications in fixed locations, such as: construction sites, interior decoration, etc. However, the pneumatic system is based on compressed gas and has the following uncontrollable characteristics: low viscosity damping, high friction, gas leakage, and high nonlinearity. Therefore, the pneumatic drive applied to the power hand tool will limit its maximum output due to the compressibility of the dust-shrinking air. At the same time, the wear of the tool is also serious. At present, the pressure of pneumatic hand tools is the industrial standard pressure of 5 to 7 bar (bar). Therefore, the output of pneumatic hand tools is also limited by the bar. (3) Liquid hand tools··The main products are liquid age grab, hydraulic bolt tensioner, clever torque wrench, hydraulic shutoff, hydraulic pile driver, jacking shears, etc. The hydraulic cylinder has good lubrication effect, and the wear of the parts under high frequency use is relatively high. Therefore, the relative viscous damping is higher than that of the pneumatic system. Therefore, the hydraulic power unit is not portable in the control of the hand tool. Will cause restrictions on use. (4) Burning power hand tools: conversion

In order to make the above features and advantages of the present invention more obvious, the following DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) The following is a detailed description of the following description of the accompanying drawings: ' ' [Embodiment] • 1 is a schematic representation of a gas-liquid hybrid drive nail grab according to an embodiment of the present invention. 1 , the gas-liquid hybrid driving nail gun is adapted to use a compressed gas, 50 as its power source. The gas-liquid hybrid driving nail grab 100 includes a pneumatic valve 110, a pneumatic cylinder 120, a hydraulic cylinder 130, and a pneumatic cylinder 130. a first piston H〇, a first piston rod 15〇, a second piston 16〇, a third piston 17〇, a first active rod 18〇, and a return element 19〇. The air valve 11〇 has an air inlet 112, wherein the compressed gas source 5 is adapted to be coupled to the inlet port 112, and the compressed gas source 50 is, for example, an air compressor for compressing air and delivering the compressed air to the port 112 by a pressure differential. The pneumatic cylinder 120 is connected to the air valve 11〇, And having a first chamber 122. The pneumatic cylinder 12 is driven by the gas pressure by the first piston 14〇, and is coupled with a hydraulic red 13〇 by the first piston rod 150, and the hydraulic cylinder 13 has a mutual communication The second chamber 132 and a third chamber 134. In the present embodiment, the second chamber 132 is converted into hydraulic pressure by the driving force of the first piston rod 15〇 by the second piston 16〇. The first piston 140 directly drives the second piston 160 by the first 200904600 • J′J x\f^ χ νψ -^3785twf.doc/p piston rod 150, and the second piston 160 is closely disposed in the second chamber 132. The middle 'is reciprocated in an axial direction within the second chamber 132. The third piston 170 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 HO is larger than the second piston 160' and the area of the third piston 170 is larger than the second piston 160, and the hydraulic cylinder 130 is filled with a liquid 136' between the second piston 160 and the third piston 170. It is a hydraulic oil with high viscosity and good lubrication. In addition, the second piston rod 180 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 applying a relative restoring force to the second piston rod 18A after the second piston rod 180 is subjected to the force of the third piston 170. In detail, in the present embodiment, the recovery element 190 is, for example, a spring. When the second piston rod 18 is driven by the third piston 170, the recovery element 190 is compressed by the pressure of the second piston rod 18〇. Deformation and store a resilience. In addition, after the nail 6 is ejected, the returning 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 nail gun 100 of the present embodiment is used to drive the nail gun 100, the compressed gas source 50 is first used to input the compressed gas, and the gas pressure valve 110 is opened. Then, the first piston 140 is driven by the gas pressure of the compressed gas source 5〇, and directly drives the second piston 160 with the first piston rod 15〇. At the same time, the second piston 160 pushes the liquid 136. When the liquid 136 is pressed by the crucible 160, the pressure is transferred to the third piston 11 200904600 ^~υA " ^3785twf.doc/p. At this time, the second piston rod 18 fixed to the third piston 17A 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 13〇, the first piston 150, the second piston 16〇 and the third piston 170 provides a conversion of the air pressure into a hydraulic pressure. Conversion interface. In addition, since the area of the first piston 14〇 is larger than that of the second piston, and the area of the third piston 170 is larger than the second piston 16〇, the area ratio of the first piston 140 to the second piston 16〇 can be designed, and The area ratio of the three pistons 170 to the first living base 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 14〇a of the first piston 14〇 receives the force A generated by the pressure of the gas, the second piston 160 is directly driven by the first piston rod 15 5 to push the liquid 136. At the same time, the liquid 136 is pushed by the second piston 16A to drive the second piston 170' to generate strength. According to the Pascal principle, if a portion of the liquid 136 in the hydraulic cylinder 13 is subjected to a pressure p, the pressure p is transmitted to each portion of the liquid 136, and the pressure is constant, that is, the unit area. The same strength. Therefore, Fi=i>a.4,, factory 2=& is, where 匕 is the gas pressure, which is the area of the surface 14〇a of the first piston 14〇, and the surface of the second piston 160 is 丨6〇 The area of & is the area of the surface 170a of the third living substrate 170. Moreover, since the area of the surface 1702 of the third piston 17〇 is larger than the area purchased by the surface of the second piston, and the area 4 of the surface 140a of the first piston 140 is larger than the area of the surface 160a of the second piston (10), the force is & will be greater than the power f, and produce 12 200904600 JL ΎΎ 785 twtw doc/p force amplification effect 'power magnification, please refer to the following formula (1): F2 ^^AlPa---(1) In addition, in gas pressure When the corpse β pushes the first piston 〖4〇, the production force is skillfully 'by the first piston rod 150 directly transmits the force to the second piston 160, and the second piston 160 converts the power Α into the liquid pressure a = coincidence / The liquid 136 flowing out of the first chamber 132 flows into the third chamber 134 in an equal volume. Due to the area ratio, the stroke D of the third piston 17〇 is less than the second piston 丨6〇. (for / 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 air-liquid mixing drive nail gun 1 , the air pressure valve 110 is closed and the gas is stopped from being applied to the first piston 140 ′. The return element 190 is restored by its restoring force. The original shape, and led to the second piston rod 18 〇 return to the original position. At this time, the third piston 170 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 15 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, first, and second living groups 140, 160, 170 and the liquid by the gas-liquid mixing drive. In addition, the Pascal principle is applied to achieve the effect of power amplification. Compared with the conventional pneumatic hand tools, no additional power source is provided under the same gas pressure, and the gas-liquid hybrid driving nail can achieve a large output output by grabbing 100. 13 200904600 ^~>\jχ ττ ^-3785twf.(loc/p

For example, in order to avoid the second piston 14 〇 spears = excessive range of motion, the liquid 136 of the hydraulic cylinder 130 overflows and the gas-liquid mixing drive nail smashes 100, and the hydraulic cylinder 13 is more likely to have - Limiting portion 139. The third limiting portion 139 is connected to one side of the third chamber phase second chamber 132 for limiting the axial movement range of the third piston 17〇. In detail, when the air pressure valve 110 is opened, the third piston 17 = moves to the liquid 136 and the second piston 160 to move, and the third movable body moves to at least the third limiting portion 139. Due to the compressibility of the liquid m, 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 falls into the third chamber 134. in. Further, the hydraulic cylinder 13G of the present embodiment may have a second limit 138' located in the second chamber 132 relative to the third chamber 134 for limiting the axial movement range of the second piston pair. In detail, after the nail 60 is ejected, the third piston 17 is subjected to recovery of the liquid 136. Then, the liquid 136' is thin. The second piston 160 is at most supported by the second chest = upper limit (four) 138, and can limit the moving distance of the liquid 136, the third living body, and the second living base 16 。. The electron ίίπ step, in the present embodiment, the gas _η. For example, it is - circulation. She is connected to the single-chip controller 27G to control _ ", Bei Yi 280 is lightly connected to the single-chip controller 27〇, which uses 14 200904600 υ^υιυχινν i3785twf.d〇c/p to feed back the sensed force Single chip controller 27〇. The single-chip controller 27 调整 can adjust the air outlet amount of the air pressure valve 11 ’ by the sensing result of the force sensor 280 and perform the stepless output adjustment of the gas-liquid hybrid driving nail. In another embodiment, not shown, the control system of the pneumatic valve 11〇 can also be designed as an open circuit. The accumulator 290 is coupled between the first chamber 122 and the pneumatic valve 11 for absorbing the reaction force generated after the nail 60 is struck, or releasing the absorbed pressure when the next nail 60 is hit. Provincial energy purpose. In detail, the accumulator 290 can include a body 292, an elastomer 294, and a fourth piston 296. The fourth piston 296 is tightly disposed within the body 292, and the spring 294 is coupled between the body 292 and the fourth piston 2%. ¥ The reaction force generated after the nail is knocked out is returned, and the spring 294 is pushed by the fourth piston 296, causing 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 is pressurized to the compressed gas to increase the output of the gas. In particular, the force sensor 280 can sense the power of the second piston rod 180 and pass back the magnitude of the power sensed to the single wafer controller 270. At this time, the single wafer controller 27 can control the amount of gas discharged from the gas pressure valve 110 by the result sensed by the force sensor 28A. In summary, the gas-liquid hybrid driving nail of the present invention has at least the following advantages: (1) using compressed gas as a power source, because the compressed gas has low cost, is easy to maintain, clean, light, easy to handle, and safe. , high temperature, 15 200904600 ^ \jx j. »τ A-3V85twf*, doc/p A wide range of operating temperature, low density, strong compressibility, large energy storage, etc., so the gas-liquid hybrid drive of the present invention The nail grab is higher than the portability of the two-handed tool, and is also more efficient than the combustion-pressure hand tool ^ 〇 (2) by the setting of the piston and the incompressibility of the liquid to convert the gas power source into a hydraulic power source. At the same time, the Pascal principle is used to achieve the effect of amplifying power, so the output power per unit weight is better than that of electric hand tools and pneumatic hand tools. In addition, the liquid can also have both cushioning and vibration absorbing effects, so the user's handling is also good. (3) The gas-liquid hybrid drive method can take into account the advantages of high hydraulic output and low weight, and high portability of the pneumatic system. Therefore, it can be used in factory production lines, etc., and the demand for high frequency of use is high. It is elastically applied to different environments and is convenient. (4) A single-chip controller, force sensor and accumulator are used to form a control and feedback system to automatically control the output of the gas-liquid hybrid drive nail. For the user, the gas-liquid hybrid driving nail of the present invention is extremely convenient to use.
