Background
The conventional pneumatic tool uses a high pressure air source to perform a rotational movement, and is applied to the working occasions of drilling, locking or releasing bolts or nuts, etc. In a conventional pneumatic tool, a pressing mechanism is generally used to control high-pressure gas to enter the pneumatic tool body so as to drive a wind driving mechanism to rotate, the wind driving mechanism is coaxially linked with a front-end oil chamber mechanism to rotate, the oil chamber mechanism is sleeved with a power shaft mechanism, and the front end of the power shaft mechanism can be connected with various tool heads to rotate, so that the purposes of drilling, locking or releasing workpieces are achieved.
When the power shaft mechanism locks the workpiece to a set torque force value, the air release device is triggered to stop the pneumatic tool at the right moment. The TWI460055 patent document discloses related prior art, in which a pulsed pneumatic tool includes an air driving mechanism, an air release mechanism and an oil chamber mechanism. Referring to fig. 1 and 2, the oil chamber mechanism generally includes an oil chamber cylinder 10, an oil storage cylinder 11, an oil pipe 12, a plug 14, a cover 15, a first locking set 16, and a second locking set 17. The oil storage cylinder 11 is accommodated in the oil chamber cylinder 10. The front end cover (not shown) and the rear end cover 18 are respectively disposed at two ends of the oil storage cylinder 11, and the rear end cover 18 has a stepped shaft hole 181, a first oil passage 182, and a second oil passage 183. The oil pipe 12 is accommodated in the oil cylinder 11 and has a third oil passage 121 and an oil hole 122. The first locking set 16 is received in the stepped shaft hole 181 with the plug seat 14. The second lock group 17 is disposed between the second oil passage 183 and the third oil passage 121. The first oil path 182 is provided with an adjusting member 184 for adjusting the size of the oil path.
By means of the cooperation of the first oil passage 182, the second oil passage 183, the third oil passage 121, the top pulling rod 191, the plug seat 14, the first locking group 16 and the second locking group 17, the flow direction of the hydraulic oil in the oil chamber mechanism is changed as shown by an arrow, especially the hydraulic flow in fig. 2, which causes the air release mechanism to release air, the air pressure no longer drives the wind driving mechanism to operate, and the power shaft stops rotating, so as to achieve the purpose of accurately removing the power of the wind driving mechanism.
The above prior art may be modified to include a first latch set 16 and an adjustment member 184.
The first locking set 16 is composed of steel balls and springs, but the contact area between the steel balls and the orifice of the plug seat 14 is too small, the orifice is not closed tightly, and there is a problem of oil leakage, so that the oil pressure born by the top detent head 19 and the top detent rod 191 is insufficient, the real-time feedback capability of the air release mechanism is affected, and the real-time responsiveness of power removal may be delayed. In addition, the spring and the steel ball are in the plug seat 14, so the cover 15 and the oil hole on the cover are additionally arranged, and the elasticity and the oil pressure of the spring can push the cover 15 away, thereby influencing the sealing performance of the cover 15 and the plug seat 14 and causing the problem of oil leakage from the gap between the cover 15 and the plug seat.
The adjusting member 184 is provided to allow the user to adjust the size of the first oil passage 182, and also affects the oil pressure of the ejector 19 and the ejector rod 191, thereby changing the feedback real-time performance of the air release mechanism. However, the user is not easy to control the operation of the adjustment member 184, and the adjustment member 184 is operated randomly, so that the effect and real-time performance of power removal are not as expected, and the user may misunderstand that the pneumatic tool is damaged.

The technical scheme of the invention is as follows: a kind of pulse type pneumatic tool power take-off unit, include a body, there are a wind to drive the organization, a air escape organization, a power shaft organization and a grease chamber organization in the body; the wind driving mechanism is driven to rotate by high-pressure gas introduced by a pressing buckle structure arranged on the main body and drives the oil chamber mechanism to rotate in a linkage manner; the oil chamber mechanism is linked with and drives the power shaft mechanism to rotate, and the power shaft mechanism is linked with and drives an oil pressure rotating shaft to rotationally lock the workpiece; when the oil pressure rotating shaft and the power shaft mechanism reach a torque force set value, the oil chamber mechanism triggers the air leakage mechanism to release high-pressure gas, so that the wind driving mechanism stops, and the oil chamber mechanism, the power shaft mechanism and the oil pressure rotating shaft stop rotating; a first locking group is arranged in the oil chamber mechanism, when the power shaft mechanism reaches a torsion set value, the pressure of hydraulic oil in the oil chamber mechanism forces the first locking group to lock a plug seat hole of a plug seat, and the hydraulic oil in the oil chamber mechanism applies pressure to the air release mechanism through a first oil path and a second oil path so that the air release mechanism releases high-pressure gas; when the wind driving mechanism stops, the reverse pressure of the hydraulic oil forces the first locking group to retreat from the plug seat, and the hydraulic oil returns to the oil chamber mechanism through the clearance between the plug seat and the first locking group;
The first locking set includes a piston member and a spring, the piston member is disposed at one end of the plug seat different from the oil draining mechanism, the spring is disposed at the end of the oil pressure rotating shaft, and the spring elastically pushes the piston member to tightly abut against the end wall of the plug seat, so as to lock the plug seat hole of the plug seat.

When the oil pressure rotating shaft of the power shaft mechanism locks a workpiece to a preset torque force, the raised oil pressure is enough to immediately push open the jacking head and the jacking rod of the pressure relief mechanism, the pressure relief mechanism feeds back pressure relief in real time, so that the pneumatic tool relieves the pneumatic power in real time, and the oil pressure rotating shaft stops rotating immediately.
The invention also improves the spring of the first locking group, and the spring is arranged at the shaft tail end of the oil pressure rotating shaft, so that the elastic force of the spring can be intensively applied to the piston piece to push the force of the piston piece for locking the end wall of the plug seat, thereby enhancing the locking capability of the piston piece.

Detailed Description
To facilitate the explanation of the present invention, the central idea shown in the above summary is expressed in terms of specific embodiments. Various objects in the embodiments are depicted in terms of scale, dimensions, amounts of distortion or displacement suitable for illustration and are not drawn to scale as actual components. In the following description, the same and symmetrically arranged components are denoted by the same reference numerals.
As shown in fig. 3, the impulse pneumatic tool of the present invention generally includes a main body 4, and a wind driving mechanism 5, a gas release mechanism 6, a power shaft mechanism 7 and an oil chamber mechanism 2 are disposed in the main body 4. The wind driving mechanism 5 is pushed to rotate by high-pressure gas introduced from the air inlet by a pressing and buckling structure 41 arranged on the main body 4, and two ends of the wind driving mechanism 5 are respectively connected with the air release mechanism 6 and the oil chamber mechanism 2; the front end of the oil chamber mechanism 2 is connected with a power shaft mechanism 7, an oil pressure rotating shaft 71 is rotated through the power shaft mechanism 7 to rotationally lock a workpiece (not shown), and the air release mechanism 6 can be triggered by the oil chamber mechanism 2 to release air when the power shaft mechanism 7 reaches a torsion set value, so that the air driving mechanism 5 stops driving the oil chamber mechanism.
As shown in fig. 3 to 6, the oil chamber mechanism includes an oil chamber cylinder 20, an oil storage cylinder 21, an oil pipe 22, a plug seat 24, a first locking set 30, and a second locking set 26.
The oil storage cylinder 21 is accommodated in the oil chamber cylinder 20, and the front end cap 27 and the rear end cap 28 are respectively provided at both ends of the oil storage cylinder 21. The rear end cover 28 has a stepped shaft hole 281 and a first oil passage 282 and a second oil passage 283; the first oil passage 282 and the second oil passage 283 are not provided with any adjuster for adjusting the size of the oil passage, in other words, the first oil passage 282 and the second oil passage 283 are constantly in unobstructed communication. The oil pipe 22 is accommodated in the oil cylinder 21, and includes a third oil passage 221 and an oil hole 222 therein. The second locking group 26 includes a ball 261 and a spring 262, the second locking group 26 is disposed between the second oil path 283 and the third oil path 221, and the elastic force of the spring 262 makes the ball 261 lock the third oil path 221.
The first locking group 30 includes a piston member 31 and a spring 32, the piston member 31 is disposed in the stepped shaft hole 281 of the rear end cover 28 and corresponds to the end wall of the plug seat 24, the spring 32 is disposed at the shaft end 711 of the oil pressure rotating shaft 71, the shaft end 711 extends into the stepped shaft hole 281 of the end cover 28, and the spring 32 elastically pushes the piston member 31 to tightly abut against the end wall of the plug seat 24, so as to lock the plug seat 24. Further, the piston member 31 includes a locking portion 311 abutting against the end wall of the plug seat 24, a piston shaft 312 extending from the center of the locking portion 311 to the plug seat hole 241 of the plug seat 24, and a sleeve portion 313 protruding from the center of the locking portion 311 for the sleeve connection of the spring 32.
As shown in fig. 3, 6 and 7, the hydraulic oil in the first oil passage 282, the second oil passage 283, the third oil passage 221 and the stepped shaft hole 281 respectively maintains a preset pressure by the cooperation of the components of the first locking group 30 locking plug seat 24, the second locking group 26 locking the third oil passage 221 and the top engine head 51 locking plug seat 24. When the wind driving mechanism 5 is pushed by the high-pressure gas introduced by the press-fastening structure 41 provided in the main body 4, the coaxial linkage oil chamber mechanism 2 rotates, the rotating motion of the oil chamber mechanism 2 pushes the oil-stirring blade 72 of the power shaft mechanism 7, and the oil pressure rotating shaft 71 of the power shaft mechanism 7 rotates to lock the workpiece. At this time, the hydraulic oil pressure in the oil reservoir 21 is not equal to the latching force of the first latching group 30 and the second latching group 26, so that the first latching group 30 still closes the plug seat hole 241 and the second latching group 26 still closes the third oil passage 221.
However, when the power shaft mechanism 7 is locked to a predetermined torque force due to the locking of the workpiece, the oil chamber mechanism 2 cannot drive the power shaft mechanism 7 to rotate, so that the pressure of the hydraulic oil in the oil storage cylinder 21 increases, and the hydraulic oil is pressurized towards the oil injection hole 222, thereby breaking through the locking capability of the second locking group 26, so that the pressure of the hydraulic oil pushes away the second locking group 26 through the oil injection hole 222 and the third oil path 221, enters the second oil path 283, passes through the first oil path 282, and enters the stepped shaft hole 281 of the rear end cover 28, and presses the top catch 51 of the wind driving mechanism 5 to axially retract and compress the spring 52. The backward pushing head 51 drives the pushing rod 53 to move backward, so as to push away the ball 61 of the air release mechanism 6, so that the high-pressure gas introduced by the press-fastening structure 41 enters the wind driving mechanism 5, and then is directly released by the air release mechanism 6, and the wind driving mechanism 5 is not driven to operate.
When the pressing structure 41 no longer introduces high-pressure gas into the wind-driving mechanism 5, the oil chamber mechanism 2 no longer rotates synchronously, so the pressure of the hydraulic oil in the oil storage cylinder 21 decreases accordingly. At this time, the release mechanism 6 pushes the ball 61 to return due to the return of the elastic member 62. The top engine head 51 (and the top engine rod 53) of the wind driving mechanism 5 is pushed by the spring 52 to return to the top forcing plug seat 24 and close the plug seat hole 241; when the top-engine head 51 and the top-engine rod 53 of the wind-driven mechanism 5 return to the original position, the hydraulic oil in the stepped shaft hole 281 is compressed, so that the hydraulic oil pushes the first locking group 30 and the second locking group 26, respectively, wherein the second locking group 26 closes the third oil passage 221 again, the piston member 31 of the first locking group 30 is pushed open by the oil pressure of the stepped shaft hole 281, the locking portion 311 is separated from the end wall of the plug seat 24, and the hydraulic oil is returned to the oil storage cylinder 21 from the gap between the piston shaft 312 and the plug seat hole 241 and the gap between the locking portion 311 and the end wall of the plug seat 24.
