Taiwan Patent Patent Publication No.: 0_6753, Patent Name: Oil Storage Accumulator, Announcement Date·2000/09/21, Application Date: 2000/01/21 Patent Abstract: The present invention relates to an oil storage accumulator, The utility model comprises a cylinder body, comprising: an oil storage chamber for supporting hydraulic oil; an oil passage connecting the oil storage chamber and the outside of the cylinder; an oil injection hole connecting the oil storage chamber and the cylinder a pressure accumulating chamber for containing compressed gas and being separated from the oil storage chamber without being connected to each other; an air inlet connecting the oil storage chamber and the outside of the cylinder as compressed air The outside of the cylinder enters the passage of the accumulator storage; an air passage connects the accumulator chamber to the outside of the cylinder as a passage for compressed air to be discharged from the accumulator chamber to the outside of the cylinder. The invention can avoid the pressure loss caused by the leakage of the pipeline sealing or the pressure supply delay due to the excessive length of the pipeline, thereby affecting the overall performance. [The invention is a bearing power-off oil pressure storage device, which utilizes an external pressure accumulating device combination The oil supply pressure of the lubricating oil between the bearing and the main shaft is kept constant. Its main purpose is 59 electric two,: the shaft axis __ mutual friction and collision = the usual invention, the first - _ this (four) device shows _. According to the Ministry of the Moon, the road bearing power-off oil (four) protection device is composed of the main shaft of the main shaft, the electromagnetic one-way check valve 41, 42 of the accumulator, the coarse filter 5, the fine _, the double-action oil system 8 . When the oil supply system 8 starts to operate, the oil supply line generates a flow pressure. After the oil supply flows out of the oil tank, the impurities in the oil supply are first filtered through the coarse rubber. Then, the oil supply is passed through the three-way three-way pipeline, and the direction is passed through the double-acting electromagnetic _7, and then stored in the accumulator 2 of the flow. In the other direction, the oil is first finely filtered through _, and the oil is passed through the main shaft i, and then returned to the fuel tank of the oil supply system 8 to complete the oil circuit. When the machine tool in the process is powered off due to external factors, and the lubricating oil supply pressure in the bearing is insufficient, the double-acting electromagnetic directional valve 7 demagnetizes the electromagnetic coil due to power failure, and the switch is switched to the reverse flow through = 'The original flow path into the accumulator is closed, and the instantaneous feedback compensation of the accumulator 2 releases the lubricating oil stored in the accumulator 2 to maintain the stable displacement force required for the oil supply, and instantly control the oil supply pressure. It has the advantages of rapid response and pressure riding. The double-acting electromagnetic directional valve 7 is interlocked with the brake in the main shaft of the main shaft. When the inertial rotation of the main shaft is completely stopped, the double-acting electromagnetic direction 7 is switched back to the original flow path, and the oil supply flow path _' accumulates H 2 In the preparation state, the release of the oil is stopped in the pipeline, and after the power source is restarted, the lubricating oil is supplied to the bearing through the power supply device of the oil supply system 8 to the bearing side. For the disclosed bearing power-off hydraulic accumulator, please refer to "first figure" to "third figure" to explain the composition of the present invention. The "first figure" is a schematic view of the device of the present invention, and the invention is composed of a main shaft accumulator 2, a throttle valve 3, a one-way check valve 4, a coarse filter 5, a fine filter 6, and a double-acting electromagnetic system. It consists of Fangguan 7 and oil supply system 8. #油油***8 starts to operate 'The lubricating oil supply line generates flow pressure. After the oil flows out of the tank, it first passes through the strainer 5 to filter the impurities in the oil supply. The "installation-three-way pipeline" shown in the "second map" allows the Linyou-direction to pass through the double-acting electromagnetic directional valve 7, and the flow is accumulating II 2 . In the other direction, the fine filter 6 is used to refine the oil supply, and after flowing through the main shaft of the main shaft, it flows back to the oil supply system 8 / from the tank to the circulation of the oil line official line. The oil supply line between the three-way pipe and the strainer $ silk-one-way stop _ 4 b one-way stop _ 41 can make the lubricating oil passing through the roughener 5 not to be finely supplied with oil. In the flow direction of the two flow directions in front of the electromagnetic directional valve 7, the I-throttle valve 3 and a one-way check valve 42 respectively, when the oil stored in the accumulator is fully loaded, the one-way stop 42 The full load of the oil can be prevented from flowing back to the pipeline. "Second®" shows that when the power tool is powered off due to factors such as man-made or natural disasters, the electromagnetic wire of one end of the double-acting electromagnetic directional valve 7 loses power. The other end of the valve spring will switch to the reverse flow, 'the original flow path is closed. The accumulating pressure H 2 immediately makes a counter-compensation, and gradually releases the (four) lubricating oil temporarily stored in the accumulator 2. The steel 3' installed between the double-acting electromagnetic directional valve 7 and the tee & road allows the constant-pressure lubricating oil released by the accumulating pressure H 2 to pass through the choke valve 3 to adjust the flow rate and then flow into the oil supply line to The pressure of the lubricating oil released by the accumulator 2 is prevented, so that the pressure of the pipeline is excessively changed. The one-way check valve 41' between the three-way line and the strainer allows the high-pressure lubricating oil released by the accumulator 2 to not flow back to the oil supply system, but sequentially passes through the three-way line, The filter 6 is finely filtered and supplied to the oil, and flows through the main shaft of the main shaft to form an oil-sliding effect between the inner surface of the bearing and the outer surface of the main shaft journal, and the main shaft_ which has not stopped yet flows back to the fuel tank of the oil supply system 8. f pressure n £槪 to the pipeline oil can compensate for the drop in oil supply pressure in the pipeline. The double-acting electromagnetic direction 7 is interlocked with the length of the main shaft of the main shaft. When the bearing power supply is powered off, the 'spindle brakes the vehicle and starts, forcing the main shaft to stop. Before the stop, the accumulator 2 supplies oil to the main shaft in the deceleration. . When the main shaft is completely stopped, the double-acting electromagnetic directional valve 7 acts to stop the release of lubricating oil into the pipeline, and the storage (4) 2 is in a ready state. After the power supply is restarted, the oil supply device via the oil supply terminal 8 The oil supply to the bearing surface is supplemented until the accumulator 2 is fully loaded.
