Description

570864 V. Description of the Invention (l) [Field of the Invention] The present invention relates to a portable pneumatic tool. [Related technical description] Portable pneumatics such as pneumatic fixed tools, metal penetrating tools, and Ξ Ξ: ΐ: ΐ air source, compressed air is generally provided by the Women ’s Wing or Ring of External Air Compression, and some external air compressors For ship-type work places, which are often fixed and are not designed to be frequently used at the site, the portable pneumatic machine S of the ship's compressor is used near the compressor. Outside of the ship type, it is also known that it is still bulky and Zhao Ji is huge and generally requires nephew :: to a location, and the portable air compressor shrinks: 5, which is also limited Because the pipe pressure is needed near the external power source, the compressor, whether it is a marine or portable type, will prevent the machine tool from conveying to the tool, but the pipe will be moved from one work place to the other: additional weight and Buzi and his love may even cause danger, and the pipe and its required accessories also cause additional costs for the user. The practical disadvantages of the portable pneumatic tools that rely on the external air shrinking machine are the two disadvantages: the tool is not the same, the above disadvantages Make it more practical. Connect to outside 2ί: of piped tools for use. Especially when it ’s difficult to reach the double u 双 that is difficult to reach, the assembly and connection are outside. Page 4 V. Description of the invention (2) The air compression is often high, and some of them drive the fixed fixtures. If all problems can be eliminated, the machine will shrink, and the flammable plug will ignite the flammable fixture. In his question, for example, a tool, these tools have remnants. Since the tool does not have both pneumatic and solid US No. 5,720, and other American tools that burn, the pump will reduce the empty body in the compressor and shrink the space.) The time it takes to press IΦ 2 is not relative to the actual working time of the tool. In item i, the time for assembling the external air compressor is even longer than the hand and time. So the user may use a hammer to manually drive the J ^ S 'βγ Pocomar-type pneumatic tool to rely on the external compressor. Some people have suggested and produced a commonly known type of wireless fixing. An internal combustion chamber is used to replace the internal pressure. It is mixed with air in a combustion chamber of a tool, and a Martian object is driven to generate pressure on a piston to drive the elimination of the pressure. When relying on external compressors, these tools produce fuel cells that require repeated purchases of specialized fuel-electricity from the manufacturer and often cannot be used on another tool. In addition, it needs to be dismantled every 30,000 operations to remove the combustion residue. The second tool uses combustion to work, and its structure is fixed with aerodynamics. Therefore, the two components cannot be interchanged, and a tool cannot be used with a tool or a wireless fixed tool. Patent Nos. 3, 1 5 4 8 8; 4, 2 1 5, 8 0 8; and 4 2 3 disclose hand-held fixing tools that do not require external air compression. Patent No. 3, 150, 488 discloses that a fixed incompressible fluid with a pump is pumped, while an incompressible fluid compresses a gas. Press the trigger on the m fixed fixture to trigger the pump to pump air, and when the air is compressed to a certain pressure (condensed air acts on a piston to drive the fixed part when the pump is running for a period of time), page 5 570864

The United States No. 4, 2 1 5 discloses a similar fixed tool, which can move the air trigger through a gear and a connecting rod to cause the motor to move the air inside. The piston is quickly driven by the force of compressed air within a certain area. Patent Nos. 8 0 and 5, 7 2 0, 4 2 3 in the disclosed fixing tool are pushed up by a piston in an electric horse, pushed up by a plug on the tool, and compressed when the piston moves up The cylinder point is not subjected to the driving force of the motor and is pushed down by the cylinder. When the piston is pushed down, it hits the motor to the extent that these fixed tools are. Press the amount, but the second compressed air is already pre-contracted.) When the piston strikes, the solid compressed air will be compressed when the outside compressed air is not good enough. After each trigger is not compressed, a certain trigger is used to reduce the work, and each work is used to reach a certain force. The additional feed of the fixed-part drive source is one or more after the three specializations are still described. A pump that immediately activates the tool. Then the release mechanism automatically makes the operating speed of the tool between the action of the tool and the force on the compressed air plug in the tool follow the degree of the piston (the tools can be moved to be flush with the surface when the tool does not return to its starting position. The additional volume of compressed air in the air tool fixed part of the air chamber acts on the piston to reduce it. The tool from compressed air relies on new and disadvantages. The first point is to press the solid to drive the fixed part, but only 'The delay between compressing the air to enough tools to actuate and drive the fixture makes it more difficult for the safety-based examiner to operate the tool. It can be basically like a spring, and the stroke linearly decreases. Unless there is a tool that can provide this feature, it will drop to zero, If there is a problem with the tool, this is completely the opposite of connecting the external operating part, because the compressed air pressure on the extra plug can be 'when the air reaches the appropriate force at the end of the stroke to fully drive the solid. To drive

Description of the invention (13) The groove (not shown) is fitted with a '俾 removably assembling mating element of an assembly. The compressor assembly 50 is slid to position in the direction of arrow a 2 in FIG. 7A, so that the shoulder 13 is combined with the groove on the cover 80 of the abrasion machine. Any required arrangement for detachably assembling the compressor assembly 50 on the cover frame 10 can be used, and the compressor assembly 50 can be detachably latched on the cover frame 10 by passing through the heart bolt 1 4 on. When the compressor assembly 50 is removed, the port 70 can accept a compressed air pipe from an external compressor. Therefore, the wireless electric nailing gun 2 can be used with an external compressor without suffering from the compressor assembly 50 weight.

In another embodiment shown in FIG. 8, a wireless pneumatic nailing gun system 3 includes a separate compressor unit 90 having a compressor assembly 50, and a cover frame 9 1 is formed around the compressor assembly 50. The power source is a battery 60 that is selectively assembled on the cover frame 91. The compressor unit 90 is carried on a belt 92 worn by the user or otherwise carried by the user. Alternatively, the compressor unit 90 may simply be placed on the floor near the work area. The tube 47 extends from the cover frame 91 and is elongated to extend between the compressor unit 90 and a standard pneumatic nailing 9 3. According to this embodiment, the use of standard pneumatic nailing 9 3 is not limited to use near a fixed external compressor, and the f shrinking machine unit 9 0 is powered by a battery and small enough to easily move with standard pneumatic nailing 9 3 To different work places. However, with the standard pneumatic hit = grab 9 3 itself does not add any weight, because the compressor assembly 50 is accommodated in the separate compressor unit 90. In each of the above embodiments, the compressor assembly 50 may include a control system for turning on and off the electric motor 50a according to the compressed air demand. in

Page 16 570864 Gas Reservoir 4 and save electricity by not allowing electricity at high pressure (when the compressor assembly is not comfortable for electric use, long-term use V. Description of the invention (14) In the simplest form, control (The electric motor is turned off when the electric pressure is turned on at a predetermined pressure. 5a is even more important when the tool is not in use). If there is no air demand, the compressor always has excessive compressed air. The work continues to run, and the control system is 50% in use. The system 0 is compressing the air motor 50a, a. The control system keeps running. This control system can be saved. A wave pressure valve is used when the bleeder is not in use. It also raises the tool when it is not in use to make the vibration and voice 0. The pressure is lower than the predetermined pressure. The motor 50a generated by the compressed air 50 is always troubled by the compressor because the compressor 501a interrupts the compressed air pressure supply of the perforations 43 of the electric horse 2 during compression. In a better flaw, the pressure is lower than a, and when the vacant value is compressed, the control is a predetermined value. This is suitable because in the example of electric system operation after the electric air is activated, the control system may include a pressure-sensitive switch (not shown in the air storage chamber 40 with a compressed air pressure higher than a predetermined value of 50 a for power supply. The switch can be installed In the cover 4. Similar to this, the switch interrupts the electric power of the electric motor 50a when the compressed air storage chamber 40 force is higher than a predetermined value. In the embodiment where the compressed air storage chamber 40 is compressed to a first predetermined value, The control system turns off the electric motor 50. The compressed air pressure of the working gas storage chamber 40 is lower than that of a second pre-started electric motor 50a; the second predetermined value is smaller than the embodiment of the control system, and the Shu motor when the tool is used can be improved. 50 a does not need to be retracted every time the tool is used. For example, in the wireless pneumatic nail gun 1, two or more nails can be struck before the motor 50 a is controlled to restart.

Page 17 570864 V. Description of the invention (15) Fill the compressed air storage chamber 4 before the two chambers 40 are driven out. Obviously, the number of tools to be struck before pressure filling can be adjusted to select the first processing job. The type and the major need are different. Two predetermined values of compressed air are used to make the pressure. Select "off" in the first position of electrical operation time. Off. Choose actually if the two predetermined values are at a 0, and then nails above the electric to shrink the air storage room 4 nails. Also in a preferred embodiment, the first and second, the first and second pre-motors 50a can be set on the tool. The size of the new compressed air storage 0 needs to be determined. The user selects the selection switch again to select And second predetermined value pieces. For example, when the pressure of different sizes and the minimum hard pressure of the workpiece (representing that the pressure of the electric horse is suitable to handle the force and the processing source is the shortest when the source is a battery, the lifter and the second predetermined value switch 1 1 0 come to position, here The position switch 1 1 0 can be provided below the "high" position if necessary. In the embodiment, the predetermined value of the control two can be used, and the user can adapt the setting value of the nail-selection switch of the desired type. The use has operating characteristics The occasion is different because it is driven. Different types of people can choose the closing pressure to allow the user to drive the nail with the force of a nail to grab the nail. The degree is doubled. The air is shrunk. If it is used up to 5 0 a The starting and processing of the workpiece. The workpiece has several advantages and is important. The second point is the comfort of use, which can be used by the user. When the selection switch is set, the other positions of the supply control can include the number of positions. The system is based on a pressure sensor 49 (the first and the first work of Figure 5), then the first is to save electricity 'electric motor 5 0 a as previously described. For example, as shown in Figure 2 more 1 1 0 The position of the power system is cut to a 'low Shu' and " high Shushu position, the first set and second set

V. Description of the invention (17) Air pressure. In Fig. 9, the value of "compressor" in a block "1" means electric, 0, and 0 a is ο η. The pressure increases with the straight motor 5 a X value as the shrinking machine 5 0 > runs. Equivalent pressure Above pma X, the control line 丄 to P m drops the electric motor 5 0 a and stops the increase in pressure. In the figure ○ Off •! Shrinker " _ The value in the "_" column indicates that the electric motor 5 0 a is 〇ff. After electric 焉 0 a 〇ff, the pressure remains the same in phase 2. 、, up to 5

In phase 3, the user presses the trigger 30 to actuate the uniform motion, so that the wireless pneumatic nail gun 1 fires a nail. As the compressed air volume $ is lost by firing the nail, the pressure in the compressed air storage chamber 40 is reduced. & The 'control circuit 100' did not start the electric motor 50a again because the pressure was not lower than Pm ot. The pressure remains the same in phase 4. In stage 5, the user presses the trigger 30 to fire the second nail. As before, the pressure dropped, this time below Pmot. In phase 6, once the measured pressure is lower than P m 0 t, the control line 丄 〇 〇 starts the electric motor 50 a to increase the grinding force. Once the pressure returns to pma x, the control circuit 100 turns off the electric motor 50 a and the pressure remains constant during phase 7. In stage 8, the user presses the trigger 30 and fires the third nail, causing the pressure to drop. The control circuit 1 0 0 does not start the electric motor 5 0 a again, because the pressure is not lower than Pmot. The pressure remains unchanged during phase 9.

Next, the function of a green light emitting diode (LED) will be explained with reference to FIG. 9. The green LED is a part of a group of green LED EDI 20 installed on the compressor cover 80. The equivalent pressure is lower than p s a f e, and the green LED is switched off by the control line operator. p s a f e is the pressure value when the trigger 3 is pressed by mistake. Wireless pneumatic nailing is less likely to occur due to firing or partial

570864 V. Description of the invention (18), the injury caused by sending a nail is because the compressed air pressure is low. From 疋, when the pressure is lower than P s a f e, there is no need to give the user a warning light. When the pressure is below P s a f e and lower than p m 丨 n, the control line 丄 〇 〇 makes the green L E D flash. The indication to the user is that the tool can cause injury if accidentally actuated. A flashing green LED will also indicate that the compressed air pressure stored in the compressed air to 40 is not sufficient to fully drive the nail. η is the minimum pressure at which the tool can fully drive the nail into the workpiece. Therefore, when the green L E D flashes, the user must be careful that the nail can be fired, and the fixture will remain on the surface of the workpiece. Once the measured power is higher than pm i η, the green D lights up, indicating that the tool can fire nails at any time. Figure 10 shows the operation of the control system in a high demand state. As before, the non-linear and pneumatic pneumatic nailing and cutting are cut to 0n in the stage, the control line 4 and the motor 5 "are started, and the measured compressed air storage room is lower than Pm0t. The compressor 50b makes The pressure value increases. The control circuit 1 00 turns off the electric motor 50 a. Tian. 'Safe, the green LED goes out, and when the pressure is between ps a 2 and m 1 n, the green LE 0 flashes. Pressure Reached p ^ Two φ ▲ LED lights up. The pressure remains the same in phase 2. At step 2 m ^ ^ ^ press the trigger 30 to fire a nail, the pressure drops due to: 辔. Product lost due to firing nails. Pressure Hold == in stage 4. In stage 5, the user repeatedly presses the trigger 30 to fire the second and fifth nails. After the second nail is hit, the pressure drops to P = two, two two, and the control line 10:00 Start the electric motor 5 〇a. Stage /, the nail is quickly fired after the fifth nail, pressure

570864 V. Description of the invention (19) Lowering below P m 1 η, the control line 丄 〇 〇 makes the green LED flash to warn the user to right-click to send the next nail, the nail will not be driven into the workpiece to a flush state. In stage 7, the compressor 50b is refilled with compressed air in the compressed-air storage chamber 40 until the pressure reaches the value of pma. At this time, the control circuit 100 turns off the electric motor 50a. The pressure remained the same during phase 8. The seventh nail was fired in stage 9 and the pressure dropped and remained unchanged during stage Θ. Figure 11 shows the operation of the control system in the idle state of the tool. In the stage work, the wireless pneumatic nailing is performed to cut to 0 n, the control circuit 丄 〇 〇 starts the electric motor 50a, and the pressure in the compressed air storage chamber 4o is charged to the pma force. The pressure remains unchanged in phase 2. A nail was hit in stage 3-the pressure thus dropped. The pressure in Phase 4 only decreased slowly due to the compressed air storage ^ 0 line leak. Even if the compressed air storage chamber 40 is designed like a '2 air seal, leakage cannot be avoided. Under phase 5 of compressed air-m〇, but the control circuit 100 did not start the electric motor ^ ^ because the control system confirms that the pressure drop is a slow leak, not π π i ′, that is, the tool is idling. In a preferred embodiment, the control system reduces the pressure to a slow leak by measuring the pressure ratio dp / dT through the control circuit 100. If the rate of change * is changed, the control line 丄 0 is carefully adjacent to the A electric motor 50a. In addition to the rate of pressure change, its g i # can be used to determine whether the tool is idling. For example, a movement sensor can be used to determine whether the tool is in idle state. The " 0 " in the " compressor " paragraph 5 in Fig. 11 indicates that the electric motor 50a is not started. Step and right-click a nail, the control line 1 〇 〇 will determine that the tool is not 57〇 864

$ 、 Explanation (20)

Once again in the idling state, and if the pressure is still below P m ot, the heartbeat circuit 1 0 0 will start the electric motor 50 a. In phase 6, when the pressure continues to drop below P m i η and the control line 1 00 continues to determine the tool position and idle state, the control line 1 0 0 disables the electric motor 50 a (; s a b 1 e). After the control circuit 100 caused the electric motor 50 a to be lost, the electric motor 50 a could not be started unless the tool was switched to i η again and the control system was completely reset. Because the pressure is now lower than the Pin i n ° control line 1 0 0, the green L E D flashes, and the red L E D flashes = it indicates that the motor is disabled. In phase 7, the compression continues to drop to psafe, 乂 I 'control line 1 0 0 turns off the green LED, and the red LED flashes ^ Phase indicates that the motor has been disabled, and the tool must be cut to 0ff to reset the control system. Brother. No 0 starting force increases 5 0 a ~ the nail changes. Stepped nails start electricity η, factor. The first 12 shows the control chart suitable for electric motors with wire electric nail gun 50 0 to P ma X. Pressure After the stage was fired, the second and the third stage of the pressure, the motor 5 a was pressed under pressure and the pressure never recovered after the six nails. The pool was made without 1 at stage a. Due to the magnitude, the control 2 kept a few forces. The next three, four and down to P m. The curve of the electric horse to pma sloped m pool capacity line pneumatic pressure 1 cut to zero pressure control line 1 P ma down. The pressure of five nails 〇t up to 5 〇a X The stage rate indicates that the nail gun 1 η under the pressure state, which is controlled below P 0 0 off X 〇 is shot in the stage, and controls the operation of the return of the strike force in stage 6. The power supply circuit of the Ming power supply 1 〇 m 〇 t 〇 Keep off the 4th in the 3rd stage of the electric motor. Hit the 1st The second line stayed in 0 0 5 and the sixth pin was recovered more slowly.

570864 V. Description of the invention (21) Because the battery 60 capacity is also consumed. Hit the seventh, eighth, and nine nails in stage 7. The recovery of pressure is slower because the capacity of the battery 60 is smaller, until the electric motor 50a is completely fired in stage 9 after the ninth nail is struck. The control circuit 1 00 detects a flameout and disables the electric motor. # Control circuit 1 〇 〇 did not turn off the electric motor 50a, its potential danger = is electric, the motor 50a may burn out during the flameout. Green 丄 E D 以 The battery should be replaced, so it should be replaced to continue to use nails. Figure 1 3 shows that the control system is held in the state of the open quick-connect valve =; grabbing port 70 of 72 is always inadvertently kept open. In stage i, the user of the IZ board filled the compression due to the pressure at Pm0, the second green electric nailing, and 50a. #Second line 1 〇00 The pressure of the electric motor 40 could not be reached, but the compressed air storage chamber changed rate Holding power = 5. Take: = ”; blinking logical steps. 彳 chanting can not tell the control system of the preferred embodiment
