Utility Model Content

[0004] This utility model provides a high-pressure filling tool for lubricating oil, which solves the problem proposed in the prior art that the filling tool does not filter the lubricating oil during filling, allowing impurities in the lubricating oil to enter the filling tool, causing blockage and low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-pressure filling tool for lubricating oil includes a support mechanism, a storage cylinder, and a cylinder cover. The cylinder cover is provided with two filtering mechanisms. Each filtering mechanism includes a filter cylinder that penetrates and is fixed to the outer wall of the cylinder cover, a support ring welded to the lower inner wall of the filter cylinder, a return spring sleeved on the lower inner wall of the filter cylinder, an mounting ring slidably sleeved on the upper inner wall of the filter cylinder, a lower filter screen embedded in the lower inner wall of the mounting ring, filter cotton abutting against the top outer wall of the lower filter screen, an upper filter screen embedded in the upper inner wall of the mounting ring, and a fixing cap screwed to the upper inner wall of the filter cylinder. A conveying assembly is provided above the cylinder cover. The conveying assembly includes an electromagnetic three-way valve screwed to the outer wall of an oil delivery pipe, two connecting pipes respectively screwed to the inner walls of both ends of the electromagnetic three-way valve, and two corrugated pipes respectively rotatably mounted on the top inner wall of the fixing cap. A filling assembly is provided below the storage cylinder, and an adjustment assembly is provided on one side of the support mechanism.

[0007] Preferably, the support mechanism includes a base plate, two support plates respectively welded to the top outer wall of the base plate, a fixing plate welded to the top outer wall of the two support plates, mounting plates respectively welded to the outer wall of the opposite side of the two support plates, and a limiting plate welded to the top outer wall of the base plate.

[0008] Preferably, the storage cylinder is inserted through and fixed to the outer wall of the fixing plate, and an oil drain pipe is fixed to the inner wall of the bottom of the storage cylinder. The cylinder cover is bolted to the outer wall of the top of the storage cylinder.

[0009] Preferably, the bottom end of the reset spring abuts against the outer wall of the top of the support ring, and the mounting ring abuts against the outer wall of the top of the reset spring, and the two bellows are respectively fixed to the outer wall of one end of the two connecting pipes.

[0010] The above scheme delivers lubricating oil to one of the filter cylinders via an oil supply pipe and a solenoid three-way valve. The upper filter screen, filter cotton, and lower filter screen filter the lubricating oil respectively. The filtered lubricating oil enters the storage cylinder. When a large amount of impurities accumulate on the upper filter screen, the solenoid three-way valve is activated to deliver the lubricating oil to the other filter cylinder. The fixing cover is removed, and the fixing cover is released from the compression of the mounting ring. Under the action of the return spring tension, the mounting ring part is located outside the filter cylinder.

[0011] Preferably, the filling assembly includes a filling pump bolted to the top outer wall of the mounting plate, a delivery hose fixed to the outer wall of the filling pump output end, and a high-pressure filling head fixed to the bottom end of the delivery hose. The filling pump is connected to the lower outer wall of the oil drain pipe via a connecting hose.

[0012] Preferably, the adjustment assembly includes an adjustment motor bolted to the top outer wall of the mounting plate, a screw connected to the bottom end of the output shaft of the adjustment motor via a coupling, a threaded plate screwed to the outer wall of the screw, a slider welded to one side of the outer wall of the threaded plate, and a connecting block welded to one side of the outer wall of the slider. The bottom end of the screw is connected to the top outer wall of the base plate via a bearing. A slide is provided on the outer wall of the limiting plate, and the slider is slidably installed in the slide. An installation port is provided on the outer wall of the connecting block, and a high-pressure filling head is embedded in the installation port.

[0013] The above scheme involves adjusting the output shaft of the motor to drive the screw to rotate, which in turn moves the threaded plate, connecting block, and high-pressure filling head, thereby adjusting the height of the high-pressure filling head. At the same time, the filling pump delivers the lubricating oil from the storage cylinder to the high-pressure filling head, thus filling the lubricating oil.

[0014] The beneficial effects of this utility model are as follows:

[0015] The oil delivery pipe and solenoid three-way valve deliver lubricating oil to one of the filter cartridges. The upper filter screen, filter cotton, and lower filter screen filter the lubricating oil respectively. The filtered lubricating oil enters the storage cylinder. When a lot of impurities accumulate on the upper filter screen, the solenoid three-way valve activates, delivering the lubricating oil to the other filter cartridge. The fixing cover is removed, and the fixing cover is released from the pressure on the mounting ring. Under the action of the return spring tension, the mounting ring part is located outside the filter cartridge. This allows the lubricating oil to be filtered before filling, preventing impurities from clogging the filling head. At the same time, it allows for quick cleaning of the filter screen, improving practicality. Attached Figure Description
