Description of the invention: [Technical field to which the invention pertains] The present invention relates to a bearing and spindle protection device, which refers to a combination of external pressure accumulating devices after the loss of oil supply power and before the ship's touch is stopped. Keep the oil supply pressure of the lubricating oil in the S line constant, and prevent the protection between the main shaft and the bearing due to the insufficient supply pressure of the lubricating oil, causing the peak _ and the bearing 乾 to rub against each other and colliding with each other. "Tian tw is powered by the power-off day". By switching the double-acting electromagnetic directional valve passage, the storage is placed in the oil supply pipeline, and the compensation is provided in the S line. The decrease of the female force and the pressure required to supply the oil. The double-acting electromagnetic directional valve is interlocked with the spindle brake. After the domain is completely stopped, the double-acting electromagnetic direction 阙 switching port supplies the oil to the path of the accumulator n. The accumulator is in a ready state. After the power is restarted, the lubricating oil is supplied to the full load state via the power supply. Brother [Prior Art] The oil stabilizer used in the technical injection includes the oil supply pressure. = Oil flow, 1 mosquito, etc. The oil supply pressure is set by the feedback mechanism to change the pressure in the pipeline to make a profit. The force is reduced, and then the fluid supply is adjusted. By controlling the fluid and operating the control, although it is possible to operate the fixed wire, it is not possible to react to the aging of the age. When the pressure changes, the 200839114 uses the previous patent with constant oil supply pressure, which is described as follows.

The invention can avoid the occurrence of pipeline sealing failure. The loss or the delay of the pressure supply due to the excessive length of the official line affects the overall performance. SUMMARY OF THE INVENTION The present invention is a bearing power-off oil pressure storage device, which utilizes an external pressure accumulating device combination to maintain the supply of lubricating oil between the bearing and the main shaft. The oil pressure is constant. Its main purpose is to make the supply of oil between the bearing and the main shaft in 200839114. It will not be caused by human factors. For example, _ switch, geostation power supply is unstable or natural disaster occurs. The electricity is supplied to the forest to make the oil, so that the bearings are not between the shafts, and the habit of the rotation of the social axis is equal to the damage caused by the miscellaneous and collision of the shafts. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a device of the present invention. The bearing power-off oil pressure storage device according to the present invention is composed of a main shaft i, an accumulator 2, a throttle 阙 3, a one-way check _, 42 , a strainer 5, a calibrator 6, and a complex The dynamic electromagnetic direction 阙7 is coupled to the oil supply system 8. When the oil supply secret 8 starts to operate, the flow pressure of the lubricating oil supply line is generated. After the oil supply is discharged from the oil, the miscellaneous oil in the aged oil is first passed through the coarse filter. Then the secret is from the three-way three-way pipeline, and after one direction passes the double-acting electromagnetic _7, the flow of the dragon 2 is in anger. The other side °J first, surplus, and read H 6 finely filter the oil supply impurities, flow through the main shaft 1 and then return to the fuel tank of the oil supply system 8 to complete the circulation of the oil circuit. When the machine tool in the process is powered off due to external factors, the lubricating oil supply pressure in the bearing is insufficient, the double-acting electromagnetic directional valve 7 is demagnetized by the electromagnetic coil, and the valve is switched to the reverse flow I. The original flow of the dragon device, the face 11 2 instant feedback compensation, release the lubricant stored in the accumulator 2 to maintain the stability of the oil supply, that is, # control oil supply, It has the advantages of rapid response and stable stability. , double-acting electricity _ 7 and the main axle (1) in the axle, when the spindle's secret rotation is all stopped, the 'double-acting electromagnetic directional valve 7 switches back to the original flow, the oil release flow _, surface H 2 Turning to the age, the oil is released into the pipeline. After the power is restarted, the lubricating oil is supplied to the bearing through the power supply device of the oil supply system 8 and is replenished to the full load state for use. [Embodiment] According to the bearing power-off hydraulic pressure storage device disclosed in the present invention, the composition of the present invention will be described with reference to "first figure" to "third figure". The "first figure" is a schematic view of the device of the present invention, and the present invention is composed of a main shaft 1, a pressure accumulating 1 § 2, a throttle valve 3, a one-way check valve 4 b 42, a coarser 5, a fine boring device 6, The double-acting electromagnetic side _ 7 and the oil supply system 8 are composed. #供油秘8 starts to operate, so that 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. As shown in the second figure, a three-way pipe is installed to allow the lubricating oil to pass through the double-acting electromagnetic directional valve 7 in one direction and then flow into the accumulator 2. In the other direction, the finer 6 will be refined again and the oil will flow through the main shaft! After the spindle spindle head, it is returned to the oil supply system 8 tank, and the circulation of the oil pipeline is completed. Between the three-way line and the strainer 5, the oil line 'installation - one-way stop _ 4 b one-way stop _ 41 can allow the oil passing through the roughener 5 to not flow back to the supply line. In the flow path of the two-two moving direction in front of the double-acting electromagnetic directional valve 7, the wire-throttle valve 3 and a one-way check valve Μ, when the lubricating oil stored in the pressure device is fully loaded, the one-way stop _ a can make the full load of oil do not flow back to the pipeline. According to factors such as man-made or natural disasters, the phenomenon of power-off of the oil supply to the lubricating oil is caused by the power line of the double-acting electromagnetic directional valve 7 to the power line, and the other is _ Lai _ switch to reverse flow, the original motorized passage is closed. The accumulator 2 immediately makes feedback compensation, and gradually releases the statistic device. The section installed between the object and the three-way road _ 3 'can allow the constant pressure lubrication released by Chuanqing 2 200839114 oil' to adjust the flow through the throttle valve 3 to flow the oil supply line to avoid the accumulator 2 The high pressure oil released is 'the pressure on the pipeline is too large. Between the three-way g road and the thick; consider the one-way check valve 41, which can make the high pressure released by the accumulator 2, the lubricating oil will not reverse the fine oil supply, and then pass through the tee Road, fine repeater 6 again - human fine; consider H flow through the main shaft of the main shaft, so that the axis between the bearing inner surface and the outer surface of the main shaft journal _ clear effect, has not stopped the axle _, return to the oil supply system 8 Head. The constant pressure lubricant released from the accumulator n 2 to the pipeline compensates for the drop in the supply pressure in the line. The double-acting "direction valve 7 is interlocked with the brake in the main shaft i of the main shaft, and the main vehicle is reduced when the bearing power supply is cut off, and starts, forcing the main shaft to stop. Before stopping, the accumulator is 2 for supplying oil to the main shaft in deceleration. . When the main shaft is completely stopped, the double-acting electromagnetic directional valve 7 is actuated to stop releasing the lubricating oil into the pipeline, and the accumulator 2 is in a ready state. After the power supply is restarted, the lubricating oil side is supplied via the power supply device of the oil supply system 8. The oil is supplied to the bearing, and the oil is supplied to the accumulator 2 in a fully loaded state for use.
