Abstract
The utility model relates to an oil seal pre-lubrication clamping fixture device with a positioning structure. To avoid dry friction between an oil seal and a shaft, pre-lubrication needs to be performed before mounting of the rotating shaft and the oil seal, but pre-lubrication effect may not exist or oil leakage caused by excessive oil after mounting may occur due to the facts that the existing pre-lubrication device is easy to cause non-uniform oiling and the oil droplet size can not be ensured. The oil seal pre-lubrication clamping fixture device with a positioning structure comprises an oil filling end cover (1), wherein the inner part of the oil filling end cover is fastened with a plug (2) through a screw (3) and a gasket; the inner part of the oil filling end cover is provided with a positioning step (10); the plug and the positioning step are in a slide fit to from a hole cavity (8) of a pneumatic oil pressure device; and the hole cavity is communicated with the pneumatic oil pressure device and directly corresponds to an oil outlet (9). The oil seal pre-lubrication clamping fixture device is used for oil seal pre-lubrication.
Description
technical field:
the utility model relates to a kind of oil sealing pre-lubrication mold device with position structure.Be specifically related to a kind of oil sealing pre-lubrication mold device with position structure.
background technique:
at present, for avoiding producing dry friction between oil sealing and axle, rotary shaft oil seal needs to carry out pre-lubrication before installing, and the pre existing lubricating fitting easily causes the painting oil mass inhomogeneous, can not guarantee the oil droplet size, causes without the pre-lubrication effect or the larger generation leakage of oil of oil mass illusion after installing.
summary of the invention:
the purpose of this utility model is to provide a kind of oil sealing pre-lubrication mold device with position structure.
above-mentioned purpose realizes by following technological scheme:
a kind of oil sealing pre-lubrication mold device with position structure, its composition comprises: the oiling end cap, described oiling end cap inside is by screw and pad and stifled fastening, described oiling end cap inside is provided with positioning step, described stifled and described positioning step slides and joins and formation is connected the vestibule of Fuel Oil Pressure Pneumatic device, and described vestibule communicates with the Fuel Oil Pressure Pneumatic device and direct corresponding oil outlet.
the described oil sealing pre-lubrication mold device with position structure, also have location counterbore and step on described oiling end cap, guarantee that between the size of positioning step upper surface diameter d and oil seal lip be interference fit simultaneously.
the described oil sealing pre-lubrication mold device with position structure, with cover on the fastening screw of described oiling end cap, compression spring, flat gasket are arranged, the height of described positioning step is 2-3mm, and described stifled diameter b is than the little 2-4mm of internal diameter c of described oiling end cap, and gap 8 is 1-2mm.
the beneficial effects of the utility model:
1. the inside that the utility model adds stifled and oiling end cap in the oiling end cap is provided with positioning step, will stifled be positioned at the inside center position of oiling end cap, simple in structure, with low cost, easy to use, long service life and to make to be coated with oil mass even; The size of d and oil seal lip are interference fit, and when after pre-lubrication, taking off oil sealing, oil droplet elongates, and have also guaranteed all even oil sealings attractive in appearance of oiling.
the utility model is used compression spring and plain washer to strengthen the ability to bear of oiling end cap between screw and oiling end cap.
the utility model is under stifled effect, and the inner distribution of oil mass of oiling end cap is equal, has guaranteed the stable of each oil outlet oil pressure, thereby has guaranteed to be coated with the even of oil mass, has reduced the waste of unnecessary grease.
the accompanying drawing explanation:
accompanying drawing 1 is structural principle schematic diagram of the present utility model.
accompanying drawing 2 is the utility model stifled structural representations used.
accompanying drawing 3 is sectional drawings of oiling end cap of the present utility model.
embodiment:
embodiment 1:
a kind of oil sealing pre-lubrication mold device with position structure, its composition comprises: oiling end cap 1, described oiling end cap is inner by screw 3 and pad 2 and stifled fastening, described oiling end cap inside is provided with positioning step 10, described stifled and described positioning step slides and joins and formation is connected the vestibule of Fuel Oil Pressure Pneumatic device, and described vestibule communicates with the Fuel Oil Pressure Pneumatic device and direct corresponding oil outlet.
embodiment 2:
the described oil sealing pre-lubrication mold device with position structure of embodiment 1 is characterized in that: also have location counterbore 6 and step 7 on described oiling end cap, guarantee that between the size of positioning step upper surface diameter d and oil seal lip be interference fit simultaneously.
embodiment 3:
the described oil sealing pre-lubrication mold device with position structure of embodiment 1 or 2, have compression spring 4, flat gasket 5 with cover on the fastening screw of described oiling end cap.
the utility model working procedure is: mold is fixed on Fuel Oil Pressure Pneumatic device worktable, oil sealing by A to being buckled on mold, make the oil sealing bottom surface uniformly with step near, startup Fuel Oil Pressure Pneumatic device, take off oil sealing with hand.Pre-lubrication mold body mainly is comprised of oiling end cap and stifled two-part, oiling end cap inside is provided with positioning step, the height e of positioning step is 2-3mm, in the inside of oiling end cap, add stifled, with screw, compression spring and flat gasket, will block up with the oiling end cap fastening, stifled with the positioning step cunning, join, stifled diameter b is than the little 2-4mm of internal diameter c of oiling end cap, and the gap 8 that described stifled and described positioning step forms vestibule 8 is 1-2mm.Lower end is provided with the location counterbore.Vestibule 8 directly communicates with the Fuel Oil Pressure Pneumatic device, the direct corresponding oil outlet 9 of vestibule.The size of d, should guarantee and oil seal lip between for interference fit.
