Description

Technical Field

[0001] This invention relates to the field of automatic lubricating oil filling technology, specifically to an automatic lubricating oil filling device. Background Technology

[0002] Lubricating oil is a non-volatile, oily lubricant used in various types of machinery to reduce friction and protect the machinery and processed parts. It is a liquid or semi-solid lubricant that mainly plays a role in lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering.

[0003] When sealing the prepared lubricating oil in drums, automatic lubricating oil dispensing equipment is usually used for quantitative dispensing. However, the existing automatic dispensing equipment has the following main problems when dispensing lubricating oil: 1. Due to the viscosity of lubricating grease, the discharge speed is slow and the grease is not completely discharged during the process of dispensing it into the oil drum. A certain amount of grease will adhere to the dispensing machine cavity, resulting in insufficient grease being dispensed into the oil drum.

[0004] 2. Usually, the oil container is placed below the oil outlet of the filling equipment, and then grease is directly added into the container. Due to its poor fluidity, the added grease will pile up and easily leak near the container opening, contaminating the work surface and affecting the sealing process.

[0005] Therefore, in order to solve the problems of slow lubricating oil filling and discharge speed, incomplete discharge, and easy accumulation and leakage of grease in the oil container, the present invention provides an automatic lubricating oil filling device. Summary of the Invention

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1. This invention provides an automatic lubricating oil dispensing device. The dispensing unit includes an oil injection section that, via a hydraulic telescopic component, moves an upward-moving piston to quantitatively draw grease from an oil storage device into a metering cylinder. The hydraulic telescopic component then pushes the piston downwards to discharge the grease from the metering cylinder, achieving quantitative dispensing. The piston-driven dispensing method increases the grease discharge speed and ensures more thorough removal of viscous grease. The storage unit uses a limiting part to clamp the oil container, keeping it in a centered position. As the oil injection section begins adding grease, a vibrating part activates, causing the oil container to oscillate up and down at a certain frequency. This ensures the added grease flows quickly and evenly within the container, preventing grease buildup and leakage. The limiting part also allows the oil container to oscillate within a certain micro-range, preventing tilting.

[0018] 2. The vibration unit is set up to drive the connecting support rod to move up and down reciprocally through the power component one, so that the storage disc slides up and down within a certain micro-range. The set spring one and spring two can provide elastic support for the storage disc, so that the storage disc can vibrate up and down stably, so that the grease in the oil container can flow quickly and evenly during the grease filling process, and avoid stacking and leakage.

[0019] 3. The limiting part is set so that when the vibrating part causes the oil drum to vibrate up and down, the clamping component can prevent the oil drum from tipping over. At the same time, the pressing component can compensate for the vibration displacement of the oil drum and prevent the oil drum from falling off the storage plate due to vibration.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 An automatic lubricating oil filling device includes: a storage unit 1 and a filling unit 2, wherein the filling unit 2 is fixedly installed at the rear end of the storage unit 1.

[0035] Please see Figure 2 and Figure 3 The storage unit 1 includes a workbench 11, a cylindrical groove 12, a vibration part 13, and a limiting part 14. The cylindrical groove 12 is provided in the middle of the upper end of the workbench 11, the vibration part 13 is provided in the cylindrical groove 12, and the limiting part 14 is fixedly installed on the upper end of the workbench 11.

[0036] Please see Figure 3 and Figure 8The filling unit 2 includes a lifting controller 21, a connecting plate 22, an extension mounting plate 23, and an oil filling part 24. The lifting controller 21 is fixedly installed at the rear end of the workbench 11. The connecting plate 22 is slidably arranged on the lifting controller 21. The extension mounting plate 23 is fixedly installed at the front end of the connecting plate 22. The oil filling part 24 is fixedly installed on the extension mounting plate 23.

[0037] First, an empty oil drum is placed on top of the vibrating part 13, and then the oil drum is clamped by the limiting part 14 to keep it in a centered position. Then, the lifting controller 21 controls the connecting plate 22 to slide down until the oil filling part 24 stops at a certain distance from the oil drum. After that, the oil filling part 24 begins to add grease into the oil drum. At the same time, the vibrating part 13 starts to work, so that the oil drum shakes up and down at a certain frequency, so that the added grease can flow quickly and evenly in the oil drum and prevent grease from piling up and leaking out. The limiting part 14 makes the oil drum shake within a certain micro-range to prevent the oil drum from tilting.

[0038] Please see Figure 3 , Figure 7 and Figure 9 The vibrating part 13 includes a second cylindrical groove 131, a third cylindrical groove 132, a first spring 133, a circular plate 134, an annular sleeve 135, a connecting rod 136, a second spring 137, and a first power component 138. The second cylindrical groove 131 is evenly distributed circumferentially at the bottom end of the first cylindrical groove 12. The third cylindrical groove 132 is distributed in the middle of the bottom end of the first cylindrical groove 12. The first spring 133 is fixedly connected to the bottom end of the second cylindrical groove 131. The circular plate 134 is fixedly connected to the upper end of the first spring 133, and the circular plate 134 slides between the circular plate 134 and the first cylindrical groove 12. The annular sleeve 135 is fixedly installed at the lower end of the circular plate 134, and slides between the annular sleeve 135 and the third cylindrical groove 132. The connecting rod 136 is fixedly installed at the lower end of the circular plate 134, located within the annular sleeve 135, and slides between the connecting rod 136 and the worktable 11. The connecting rod 136 is fitted with a spring 137. One end of the spring 137 is fixedly connected to the circular plate 134, and the other end is fixedly connected to the bottom end of the cylindrical groove 132. The worktable 11 is equipped with a power assembly 138, which is hinged to the connecting rod 136. After the oil drum is placed on the circular plate 134 and elastically limited by the limiting part 14, the power assembly 138 is activated. The power assembly 138 drives the connecting rod 136 to move up and down, so that the circular plate 134 slides up and down within a certain micro-range. The springs 133 and 137 can elastically support the circular plate 134, so that the circular plate 134 can vibrate up and down stably. This allows the oil in the oil drum to flow quickly and evenly during the oil filling process, preventing it from piling up and leaking out.

[0039] Please see Figure 7 and Figure 9 The power assembly 138 includes an eccentric shaft 1381, a transmission rod 1382, and a motor 1383. The eccentric shaft 1381 is rotatably connected to the worktable 11, and the transmission rod 1382 is hinged to the eccentric shaft 1381. The upper end of the transmission rod 1382 is hinged to the connecting support rod 136. The motor 1383 is fixedly installed on the worktable 11 and in front of the eccentric shaft 1381. The output shaft of the motor 1383 is fixedly connected to the eccentric shaft 1381. The motor 1383 drives the eccentric shaft 1381 to rotate, and the eccentric shaft 1381 drives the transmission rod 1382 to swing, which ultimately causes the connecting support rod 136 to move up and down reciprocally, realizing the vibration of the circular plate 134.

[0040] Please see Figure 2 , Figure 3 and Figure 4 The limiting part 14 includes a positioning plate 141, a bidirectional threaded rod 142, a sliding plate 143, a clamping assembly 144, a pressing assembly 145, and a power assembly 146. Positioning plates 141 are symmetrically fixedly installed on the upper end of the worktable 11. The bidirectional threaded rod 142 is symmetrically rotatably connected between the positioning plates 141. Sliding plates 143 are symmetrically slidably arranged on the upper end of the worktable 11 between the positioning plates 141, and are threadedly connected to the bidirectional threaded rod 142. A clamping assembly 144 is fixedly installed at the end of the sliding plate 143 away from the positioning plate 141. Pressing assemblies 145 are evenly fixedly installed on the upper end of the clamping assembly 144. The positioning plate on the right side... A second power assembly 146 is fixedly installed on the right end of 141. The second power assembly 146 is fixedly connected to the rear bidirectional threaded rod 142. The second power assembly 146 causes the two bidirectional threaded rods 142 to rotate synchronously, thereby driving the sliding plate 143 to move in opposite directions. This allows the clamping assembly 144 to center and stabilize the oil drum. When the clamping assembly 144 moves relative to the oil drum, the pressing assembly 145 on it moves to the upper edge of the oil drum to press against it. When the vibrating part 13 causes the oil drum to vibrate up and down, the clamping assembly 144 can prevent the oil drum from tipping over. At the same time, the pressing assembly 145 can compensate for the vibration displacement of the oil drum and prevent the oil drum from detaching from the storage circular plate 134 due to vibration.

[0041] Please see Figure 4The second power assembly 146 includes a second motor 1461, pulleys 1462, and a transmission belt 1463. The second motor 1461 is fixedly mounted on the right end of the positioning plate 141 on the right side via a motor mount. The output shaft of the second motor 1461 is fixedly connected to the rear bidirectional threaded rod 142. Each bidirectional threaded rod 142 is fixedly mounted with a pulley 1462, and the pulleys 1462 are connected to each other via the transmission belt 1463. The second motor 1461 drives the rear bidirectional threaded rod 142 to rotate, and the rotation of the rear bidirectional threaded rod 142 drives the pulleys 1462 on it to rotate synchronously. Then, the transmission belt 1463 realizes the rotation of the front pulley 1462, thus ultimately achieving the synchronous rotation of the two bidirectional threaded rods 142.

[0042] Please see Figure 3 , Figure 4 and Figure 5 The clamping assembly 144 includes a fixed connecting block 1441, an arc-shaped mating block 1442, a clearance groove 1443, an ejector slider 1444, and a spring 1445. The fixed connecting block 1441 is fixedly installed at one end of the sliding plate 143 away from the positioning plate 141. The arc-shaped mating block 1442 is fixedly installed at the other end of the fixed connecting block 1441 away from the sliding plate 143. Clearance grooves 1443 are evenly distributed along the arc surface of the arc-shaped mating block 1442. An ejector slider 1444 is slidably mounted on the clearance groove 1443. A spring 1445 is installed inside. One end of the spring 1445 is fixedly connected to the ejector slider 1444, and the other end is fixedly connected to the wall of the allowance groove 1443. During the relative movement of the sliding plate 143, the arc-shaped mating block 1442 will follow and approach the outer wall of the oil drum. The ejector slider 1444 contacts the outer wall of the oil drum to center and limit its movement. At the same time, when the oil drum vibrates up and down, the combined action of the ejector slider 1444 and the spring 1445 can make the oil drum shake to the maximum extent without tipping over.

[0043] Please see Figure 3 and Figure 6The pressing assembly 145 includes a positioning rod 1451, a connecting plate 1452, an automatic telescopic rod 1453, a pressure block 1454, and a spring 1455. The positioning rod 1451 is evenly fixedly installed on the upper end of the arc-shaped mating block 1442. The connecting plate 1452 is fixedly installed on the positioning rod 1451. The automatic telescopic rod 1453 is fixedly installed on the lower end of the connecting plate 1452. The pressure block 1454 is fixedly installed on the lower end of the automatic telescopic rod 1453. A spring is sleeved on the automatic telescopic rod 1453. Spring 1455 is fixedly connected at one end to connecting plate 1452 and at the other end to pressure block 1454. The positioning rod 1451 is provided to allow pressure block 1454 to slide and press against the upper edge of the oil drum. When the vibrating part 13 is working, the automatic telescopic rod 1453 and spring 1455 work together to keep pressure block 1454 pressed against the upper edge of the oil drum and elastically limit its movement, preventing excessive vibration of the oil drum and leakage of the oil inside.

[0044] Please see Figure 3 and Figure 8 The oil filling unit 24 includes a metering cylinder 241, an oil inlet pipe 242, a first valve 243, a second valve 244, a mating piston 245, an inverted L-shaped positioning component 246, and a hydraulic telescopic component 247. The metering cylinder 241 is fixedly installed on the upper end of the mounting plate 23. The oil inlet pipe 242 is fixedly installed on the left end of the lower oil outlet pipe of the metering cylinder 241. A first valve 243 is installed inside the oil inlet pipe 242, and a second valve 244 is installed inside the oil outlet pipe. The mating piston 245 is slidably installed inside the metering cylinder 241. An inverted L-shaped positioning component 246 is fixedly installed on the upper end of the mounting plate 23 and located behind the metering cylinder 241. A hydraulic telescopic component 247 is fixedly installed on the inverted L-shaped positioning component 246. The telescopic rod of the hydraulic telescopic component 247 is fixedly connected to the mating piston 245, and the hydraulic... The telescopic rod of the hydraulic telescopic component 247 is connected to the metering cylinder 241 by a sliding fit. Before use, the oil inlet pipe 242 is fixedly connected to the oil outlet pipe on the device for storing large amounts of grease. Initially, valve 244 is closed and valve 1 is open. The telescopic rod of the hydraulic telescopic component 247 moves the piston 245 upward, which can draw the grease in the oil storage device into the metering cylinder 241 in a metered manner. Then, valve 1 is closed and valve 244 is opened. The telescopic rod of the hydraulic telescopic component 247 pushes the piston 245 to discharge the grease in the metering cylinder 241 downward, thus achieving metered dispensing. The use of the piston 245 to push the grease increases the grease discharge speed and makes the viscous grease more thoroughly discharged.

[0045] The working principle of this invention is as follows: First, an empty oil drum is placed on the upper end of the vibrating part 13, and then the oil drum is clamped by the limiting part 14 to keep it in a centered position. Then, the lifting controller 21 controls the connecting plate 22 to slide downward until the oil filling part 24 stops at a certain distance from the oil drum. After that, the oil filling part 24 begins to add grease into the oil drum. At the same time, the vibrating part 13 starts to work, so that the oil drum shakes up and down at a certain frequency, so that the added grease can flow quickly and evenly in the oil drum and avoid grease accumulation and leakage. The limiting part 14 makes the oil drum shake within a certain micro-range to prevent the oil drum from tilting.
