[0003] When assembling the hydraulic shock absorber, it is necessary to fill the oil storage barrel of the hydraulic shock absorber with oil. When filling the oil storage barrel with oil, a channel oil filling device is required. Although the existing oil filling device can perform basic oil filling operations on the oil storage barrel, after completing the oil filling operation of one oil storage barrel, it is necessary to remove the oil storage barrel that has been filled with oil and replace it with an oil storage barrel that has not been filled with oil. Only then can the oil filling device be started again for the next oil filling. This method of oil filling greatly affects the oil filling efficiency of the oil storage barrel, and therefore it needs to be improved. Utility Model Content

[0023] The operator starts the first pneumatic cylinder 3, so that the first pneumatic cylinder 3 drives the connecting plate 4 to descend, thereby the connecting plate 4 drives the oil filling nozzle 6 to move downward, so that the connecting plate 4 contacts the oil inlet of the oil storage barrel, and the oil storage barrel can be filled with oil. After the oil filling is completed, the motor 7 can be started to make the rotating shaft 8 drive the rotating rod 9 to rotate, so that the hinged rod 10 pushes the movable plate 2 to move to the left, so that the oil filling nozzle 6 can be moved to the top of the oil storage barrel that is not filled with oil.

[0024] A fixing block 11 is fixedly installed on the top of the back side of the shell 1 , and an oil storage tank 12 is fixedly installed on the bottom of the back side of the shell 1 .

[0025] By providing the oil storage tank 12 , an operator can store oil inside the oil storage tank 12 .

[0026] Among them, an oil pump 13 is fixedly installed on the top of the oil storage tank 12, and an oil inlet pipe 14 is fixedly installed on the bottom of the oil pump 13. The bottom end of the oil inlet pipe 14 penetrates the oil storage tank 12 and extends to the inside of the oil storage tank 12.

[0035] An operator can open the sealing cover 25 by rotating it, so as to replenish oil into the oil storage tank 12 through the fixed pipe 24 .

[0036] The working principle and use process of this utility model:

[0037] First, the operator places the oil storage barrel between the three clamping blocks 18, and then starts the second pneumatic cylinder 21, so that the second pneumatic cylinder 21 drives the lifting plate 22 to move downward, so that the lifting plate 22 drives the three push-pull rods 23 to move, and then the push-pull rods 23 drive the clamping blocks 18 to move through the slide plate 20 and the connecting block 19, so that the three clamping blocks 18 can move inward at the same time, and then the oil storage barrel can be clamped and fixed to prevent the oil storage barrel from tipping over.

[0038] The operator starts the first pneumatic cylinder 3, so that the first pneumatic cylinder 3 drives the connecting plate 4 to descend, so that the oil filling nozzle 6 contacts the oil filling hole of the oil storage barrel, and then starts the oil pump 13, so that the oil inlet pipe 14 sucks the oil inside the oil storage tank 12, and then injects the oil into the oil storage barrel through the oil outlet pipe 15 and the oil filling hose 5. When the oil filling is completed, the operator can start the first pneumatic cylinder 3 again, so that the first pneumatic cylinder 3 drives the connecting plate 4 to reset, and then starts the motor 7, so that the rotating shaft 8 drives the rotating rod 9 to rotate, so that the hinged rod 10 can push the movable plate 2 to move horizontally to the left, so that the oil filling nozzle 6 moves to the top of the oil storage barrel that has not been filled with oil, so that the oil filling operation can continue. During this period, the operator can remove the oil storage barrel on the right side that has been filled with oil and replace it with an empty barrel, thereby avoiding the shutdown of the device during the replacement of the oil storage barrel, thereby improving the oil filling efficiency.
