Embodiment
Referring to Fig. 1 and Fig. 2, oil sealing pre-lubrication device of the present utility model comprises oil feed device and oiling station 2, and above-mentioned oil feed device and oiling station 2 are installed on the worktable.Described oil feed device has oil storage cylinder 1, be provided with piston 1-3 in the oil storage cylinder 1, piston 1-3 upper chamber is shoe cream room 1-1, lower chamber is pneumatic cavity 1-2, lubricant oil 4 is housed in the shoe cream room 1-1, and described oil storage cylinder 1 bottom is connected with pneumatic regulation unit 5, and the outlet of pneumatic regulation unit 5 is communicated with pneumatic cavity 1-2, thereby can keep certain pressure, oiling station 2 is in to oil condition.
Described oiling station 2 comprises pedestal 2-1, regulates collar 2-2, follower 2-3, oil sealing platform 2-4 and newel 2-5.Described pedestal 2-1 adopts screw thread to be connected with described oil feed device top.Described pedestal 2-1 outer circumferential face adopts the described adjusting collar 2-2 that has been threaded, and has stroke chamber 2-2-1 in the described adjusting collar 2-2.By the screw thread of rotation adjusting collar 2-2, the adjusting collar is moved up and down, and then can adjustment stroke.The stroke size has determined to give oil mass.Described follower 2-3 is housed on the described pedestal 2-1, and described follower 2-3 has spring chamber 2-3-1, in the described spring chamber 2-3-1 spring 2-8 is housed, and described follower 2-3 bottom has boss 2-3-2, and described boss 2-3-2 is contained in the described stroke chamber 2-2-1.Described pedestal 2-1 adopts engage thread to be connected with described newel 2-5 in the middle part, described newel 2-5 has the oil duct 2-7 that is communicated with described oil storage cylinder 1, described oil duct 2-7 top is communicated with oil road 2-6, described newel 2-5 is set with described oil sealing platform 2-4 outward, and described oil sealing platform 2-4 and described follower 2-3 are by being threaded.Be under the free state at spring 2-8, oil sealing platform 2-4 seals oil road 2-6, and lubricant oil 4 can not flow out.
During work, the piston 1-3 of oil storage cylinder 1 goes into oil pressure oiling station 2 in the oil feed device under the effect of air pressure.When oiling station 2 was not stressed P, oil sealing platform 2-4 and adjusting collar 2-2 sealed the oil road 2-6 of newel 2-5 under the support force effect of spring 2-8, lubricant oil 4 can't be leaked.When oil sealing 3 is put into oiling station 2, and when exerting pressure P, oil sealing platform 2-4 and to regulate collar 2-2 pressure spring 2-8 descending opens the oil road 2-6 of newel 2-5, lubricant oil 4 is discharged from oil road 2-6 under gas pressure, smear to the main lip place of oil sealing 3, after arriving state shown in Figure 2, unclamp pressure, take off oil sealing 3, spring 6 reinstatements, oil sealing platform 2-4 and adjusting collar 2-2 seal the oil road 2-6 of newel 2-5 again, and inunction process is finished.
Wherein, what of oil mass oil sealing platform 2-4 and regulate the stroke can regulate control of collar 2-2 can adjust by the stroke that changes oil sealing platform 2-4 and regulate collar 2-2, thereby realize quantified controlling.Because the reason of size, a kind of oil sealing of specification needs corresponding a kind of oiling station, but oiling station of the present utility model only needs to change oil sealing platform 2-4 and newel 2-5 can satisfy the needs of changing specification, reduces cost greatly, enhances productivity.
The utility model reasonable in design can continue oil supply, quantified controlling oil pump capacity, enhances productivity.Worktable is provided with oil feed device and oiling station 2, and oil feed device is by the lasting oil supply of air pressure realization to oiling station 2, by oil sealing 3 being exerted pressure and controlling oil sealing 3 strokes and realize oiling.
