Description

Technical Field

[0001] The utility model relates to the technical field of oil supply systems, in particular to a lubricating hydraulic oil supply system. Background Art

[0002] Since hydraulic technology has the advantages of light weight, small size and small inertia, the pressure source of most contemporary mechanical manufacturing is hydraulic technology, and the coordination and operation between parts are inseparable from the lubrication and heat dissipation of lubricating oil. Therefore, the oil supply of lubricating hydraulics is particularly important.

[0003] For convenience, most existing lubrication and hydraulic oil supply systems supply lubricating oil and hydraulic oil synchronously, resulting in oil supply when one of them does not need oil supply, but the other one will supply oil as the other one is in operation, causing waste and increasing production costs. Alternatively, the two oil supply systems are completely separated, which increases the system size and the number of parts, takes up a lot of space, and has high manufacturing costs.

[0004] There is a need for a device that integrates lubrication and hydraulic oil supply and can supply oil separately according to demand to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a lubricating hydraulic oil supply system to solve the problems raised in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: the lubricating hydraulic oil supply system includes a box body, a partition is installed in the box body, the partition divides the box body into a hydraulic oil chamber and a lubricating oil chamber, the hydraulic oil chamber is provided with a hydraulic outlet, a hydraulic oil pipe is installed on the hydraulic outlet, a lubrication outlet is provided in the lubricating oil chamber, a lubricating oil pipe is installed on the lubrication outlet, a hydraulic pressure plate and a lubricating pressure plate are respectively slidably installed in the hydraulic oil chamber and the lubricating oil chamber, screws are installed on the hydraulic pressure plate and the lubricating pressure plate, a mounting plate is installed on the partition, and a drive The driving motor is rotatably installed on the mounting plate, and the driving gear is sleeved on the output shaft of the driving motor. Two transmission gears are symmetrically installed on the mounting plate, and a retaining ring is installed on the two transmission gears. The two screws are threaded with a screw sleeve, and the screw sleeve is sleeved in the transmission gear. Four electric telescopic blocks are evenly distributed on the screw sleeve, and a control panel is installed on the box body. A hydraulic oil supply switch and a lubricating oil supply switch are installed on the control panel. The hydraulic oil supply switch and the lubricating oil supply switch are electrically connected to the electric telescopic blocks on the screw sleeves in the corresponding oil chambers respectively.

[0007] As an optimal technical solution, the bottoms of the hydraulic oil chamber and the lubricating oil chamber are both arc-shaped, and the hydraulic outlet and the lubrication outlet are both arranged at the lowest point of the arc. The arc shape of the bottom of the box body can cause the liquid to converge toward the middle, thereby speeding up the oil supply. At the same time, most of the liquid can flow out of the pipeline through the convergence and will not remain in the box body, thereby improving the utilization rate of hydraulic oil and lubricating oil and reducing waste.

[0008] As an optimal technical solution, the hydraulic oil pipe is a one-way pipe, the density of the hydraulic pressure plate is less than the density of the hydraulic oil, and the density of the lubricating pressure plate is less than the density of the lubricating oil. The one-way pipe prevents the pressure generated by the hydraulic components during operation from forcing the hydraulic oil to flow back and contaminating the unused hydraulic oil in the hydraulic oil chamber. The hydraulic pressure plate and lubricating pressure plate with lower density can ensure that the pressure plate will not generate excessive pressure on the liquid, and prevent the pressure plate from moving down and the liquid from flowing out due to gravity when oil supply is not needed.

[0009] As an optimal technical solution, buffer springs are installed under the hydraulic pressure plate and the lubrication pressure plate, pressure sensors are installed on the two buffer springs, a hydraulic oil level indicator light and a lubricating oil level indicator light are installed on the mounting plate, the pressure sensor under the hydraulic pressure plate is electrically connected to the hydraulic oil level indicator light, and the pressure sensor under the lubrication pressure plate is electrically connected to the lubricating oil level indicator light.

[0010] As an optimal technical solution, a lubricating oil filter box is installed on the lubricating oil chamber, a slot is provided in the lubricating oil filter box, a mounting port is provided on the wall of the lubricating oil filter box away from the slot, the mounting port is higher than the slot, the slot and the mounting port are connected through a first filter plate, a second filter plate is horizontally installed in the lubricating oil filter box, the second filter plate is located below the first filter plate, a through hole is provided at the bottom of the lubricating oil filter box, an oil return pipe is installed on the through hole, and the oil return pipe passes through the lubricating pressure plate.

[0011] As an optimal technical solution, the oil return pipe is a one-way pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The oil supply is controlled by the screw, and the hydraulic oil and lubricating oil can be supplied separately according to the needs, which will not cause oil waste and effectively reduce production costs.

[0014] 2. Through the setting of buffer spring and pressure sensor, the lack of oil can be detected and the oil can be replenished in time without causing the machine to stop operating immediately.

[0015] 3. By setting the second filter plate of the first filter plate, the used lubricating oil can be filtered to achieve reuse and improve utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: Figures 1-6As shown, the utility model provides a technical solution for a lubricating hydraulic oil supply system, characterized in that: the lubricating hydraulic oil supply system includes a box body 1, a partition 2 is installed in the box body 1, and the partition 2 divides the box body 1 into a hydraulic oil chamber 3 and a lubricating oil chamber 4. The hydraulic oil chamber 3 is provided with a hydraulic outlet 5, and a hydraulic oil pipe 7 is installed on the hydraulic outlet 5. The lubricating oil chamber 4 is provided with a lubricating outlet 6, and a lubricating oil pipe 8 is installed on the lubricating outlet 6. Hydraulic pressure plates 9 and lubricating oil chambers 3 and 4 are respectively slidably installed. Sliding plate 10, the hydraulic pressure plate 9 and the lubricating pressure plate 10 are both equipped with a screw 11, the partition 2 is equipped with a mounting plate 12, the mounting plate 12 is equipped with a drive motor 13, the mounting plate 12 is rotatably equipped with a drive gear 14, and the drive gear 14 is sleeved on the output shaft of the drive motor 13, the mounting plate 12 is symmetrically equipped with two transmission gears 15, the two transmission gears 15 are both equipped with a retaining ring 16, the two screws 11 are threaded with a screw sleeve 17, and the screw sleeve 17 is It is sleeved in the transmission gear 15, and four electric telescopic blocks 18 are evenly distributed on the screw sleeve 17. A control panel 19 is installed on the box body 1. A hydraulic oil supply switch 20 and a lubricating oil supply switch 21 are installed on the control panel 19. The hydraulic oil supply switch 20 and the lubricating oil supply switch 21 are electrically connected to the electric telescopic blocks 18 on the screw sleeve 17 in the corresponding oil chamber respectively. When hydraulic oil supply is required, the hydraulic oil supply switch 20 on the control panel 19 is turned on to control the corresponding electric telescopic block 18 to extend and press the transmission gear 15. At this time, the driving motor 13 drives the screw sleeve 17 to rotate through the driving gear 14 and the transmission gear 15. Since the screw sleeve 17 is threaded with the screw rod 11, the rotation of the screw sleeve 17 will cause the screw rod 11 to move downward, thereby driving the hydraulic pressure plate 9 to move downward. Through the extrusion force, the hydraulic oil is supplied to the required components. When supplying lubricating oil, the lubricating oil supply switch 21 is turned on. The same principle as the hydraulic oil supply is used to supply oil. Hydraulic oil and lubricating oil can be supplied separately, which will not cause oil waste and effectively reduce production costs.

[0025] The bottoms of the hydraulic oil chamber 3 and the lubricating oil chamber 4 are both arc-shaped, and the hydraulic outlet 5 and the lubricating outlet 6 are both arranged at the lowest point of the arc. The arc shape of the bottom of the box body 1 can cause the liquid to converge toward the middle, thereby speeding up the oil supply. At the same time, most of the liquid can flow out of the pipeline through the convergence and will not remain in the box body 1, thereby improving the utilization rate of hydraulic oil and lubricating oil and reducing waste.

[0026] The hydraulic oil pipe 7 is a one-way pipe, the density of the hydraulic pressure plate 9 is less than that of the hydraulic oil, and the density of the lubricating pressure plate 10 is less than that of the lubricating oil. The one-way pipe prevents the pressure generated by the hydraulic components during operation from forcing the hydraulic oil to flow back and contaminating the unused hydraulic oil in the hydraulic oil chamber 3. The hydraulic pressure plate 9 and the lubricating pressure plate 10 with lower density can ensure that the pressure plate will not generate excessive pressure on the liquid, and prevent the pressure plate from moving down and the liquid from flowing out due to gravity when oil supply is not needed.

[0027] like Figure 1-Figure 2 and Figure 5 As shown, buffer springs 22 are installed under the hydraulic pressure plate 9 and the lubricating pressure plate 10, and pressure sensors 23 are installed on the two buffer springs 22. A hydraulic oil level indicator light 24 and a lubricating oil level indicator light 25 are installed on the box body 1. The pressure sensor 23 under the hydraulic pressure plate 9 is electrically connected to the hydraulic oil level indicator light 24, and the pressure sensor 23 under the lubricating pressure plate 10 is electrically connected to the lubricating oil level indicator light 25. As the oil level continues to decrease, the position of the pressure plate will gradually move downward. When the pressure sensor 23 touches the bottom of the box body 1, the corresponding indicator light will flash, reminding the staff that the oil level is insufficient and needs to be replenished in time. The setting of the buffer spring 22 causes an alarm to be triggered when there is still a small amount of oil, but it does not affect the ongoing oil supply work, thereby ensuring the normal operation of the machinery.

[0028] like Figure 1-Figure 3 As shown, a lubricating oil filter box 26 is installed on the lubricating oil chamber 4, and a slot 27 is provided in the lubricating oil filter box 26. A mounting port 28 is provided on the wall of the lubricating oil filter box 26 away from the slot 27. The mounting port 28 is higher than the slot 27. The slot 27 and the mounting port 28 are connected by a first filter plate 29. A second filter plate 30 is horizontally installed in the lubricating oil filter box 26. The second filter plate 30 is located below the first filter plate 29. A through hole 31 is provided at the bottom of the lubricating oil filter box 26. An oil return pipe 32 is installed on the through hole 31, and the oil return pipe 32 passes through Lubricate the pressure plate 10. The lubricating oil will carry away the waste debris generated by the friction of the parts during use. When it is reused for the second time, it needs to be filtered. The tilted first filter plate 29 can increase the filtering area and improve the filtering efficiency. After the first filter plate 29 has been used for a long time, in order to maintain the filtering efficiency, the accumulated filter material needs to be cleaned. The first filter plate 29 can be pulled out from the installation port 28 for cleaning. At this time, the second filter plate 30 can replace the first filter plate 29 to filter the lubricating oil until the first filter plate 29 is reinstalled, thereby realizing the reuse of the lubricating oil and effectively reducing production costs.

[0029] The oil return pipe 32 is a one-way pipe to prevent the liquid in the lubricating oil chamber 4 from being squeezed by the force when the lubricating oil is supplied, causing the lubricating oil to flow back into the lubricating oil filter box 26 along the oil return pipe 32. The one-way oil return pipe 32 can prevent the backflow of the lubricating oil.

[0030] The working principle of this utility model:

[0031] When hydraulic oil supply is needed, turn on the hydraulic oil supply switch 20 on the control panel 19, control the corresponding electric telescopic block 18 to extend, and press the transmission gear 15. At this time, the drive motor 13 drives the screw sleeve 17 to rotate through the drive gear 14 and the transmission gear 15. Since the screw sleeve 17 is threaded with the screw rod 11, the rotation of the screw sleeve 17 will cause the screw rod 11 to move downward, thereby driving the hydraulic pressure plate 9 to move downward. Through the extrusion force, the hydraulic oil is supplied to the required components. When supplying lubricating oil, turn on the lubricating oil supply switch 21, which is the same as the hydraulic oil supply principle, to supply oil, which can realize the separate supply of hydraulic oil and lubricating oil, will not cause oil waste, and effectively reduce production costs.

[0032] The arc shape at the bottom of the box body 1 can cause the liquid to converge toward the middle, speeding up the oil supply. At the same time, the convergence can make most of the liquid flow out of the pipeline and will not remain in the box body 1, thereby improving the utilization rate of hydraulic oil and lubricating oil and reducing waste.

[0033] The hydraulic oil pipe 7 is a one-way pipe, and the hydraulic pressure plate 9 and the lubricating pressure plate 10 are both made of a material with a lower density. The one-way pipe prevents the pressure generated by the hydraulic components during operation from forcing the hydraulic oil to flow back and contaminating the unused hydraulic oil in the hydraulic oil chamber 3. The hydraulic pressure plate 9 and the lubricating pressure plate 10 with lower density can ensure that the pressure plate will not generate excessive pressure on the liquid, preventing the pressure plate from moving down and the liquid from flowing out due to gravity when oil supply is not needed.

[0034] As the oil volume continues to decrease, the position of the pressure plate will gradually move downward. When the pressure sensor 23 touches the bottom of the box body 1, the corresponding indicator light will flash to remind the staff that the oil volume is insufficient and needs to be replenished in time. The setting of the buffer spring 22 causes an alarm to be triggered when there is still a small amount of oil, but it does not affect the ongoing oil supply work, thereby ensuring the normal operation of the machine.

[0035] During use, the lubricating oil will carry away the waste debris generated by the friction of parts. When it is reused for the second time, it needs to be filtered. The tilted first filter plate 29 can increase the filtering area and improve the filtering efficiency. After the first filter plate 29 has been used for a long time, in order to maintain the filtering efficiency, the accumulated filter material needs to be cleaned. The first filter plate 29 can be pulled out from the installation port 28 for cleaning. At this time, the second filter plate 30 can replace the first filter plate 29 to filter the lubricating oil until the first filter plate 29 is reinstalled, thereby realizing the reuse of the lubricating oil and effectively reducing production costs.

[0036] The oil return pipe 32 is a one-way pipe to prevent the liquid in the lubricating oil chamber 4 from being squeezed by the force when the lubricating oil is supplied, causing the lubricating oil to flow back into the lubricating oil filter box 26 along the oil return pipe 32. The one-way oil return pipe 32 can prevent the backflow of the lubricating oil.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
