Description

The oil sealing erector
Technical field
The utility model relates to a kind of mechanical maintenance tool in use, specifically is a kind of oil sealing erector.
Background technology
In mechanical transmissioning piece; Rotating shaft is easy to the oil sealing that it is peripheral and weares and teares, like the oil sealing in the oil sealing on the machine shaft, the speed changer rotating shaft, the oil sealing in the hydraulic press rotating shaft etc. owing to rotate for a long time; In a single day oil sealing is worn or damages; Just should in time change, leakage of oil, oil impregnate will take place, thereby cause mechanical disorder like untimely replacing.But in flight-line maintenance, the new oil-sealing sleeve after will changing with hand is unusual difficulty in rotating shaft, because be provided with inner lip and outer lip in the endoporus of oil sealing; Inner lip is hard slightly; Outer lip is soft slightly, and its material all is a rubber generally, and the surface of rotating shaft is more coarse; So will oil-sealing sleeve be wasted time and energy very much, will damage oil sealing slightly because of carelessness in rotating shaft.A kind of device that oil sealing is installed is disclosed on the State Intellectual Property Office website; Its Granted publication number is called the patent of oil sealing erecting device for CN 201677166U, name; Its technical scheme is: it comprises a cylindrical body, and it is cambic gradually pre-small post-large that the external diameter of the cylinder of cylindrical body is, and is set to cylindrical hole in the cylindrical body; The aperture of cylindrical hole is equal to or greater than the external diameter of rotating shaft, and the front end face or the outer wall of cylindrical body are provided with steam vent; This oil sealing erecting device in use; The cylindrical body of oil sealing erecting device is passed the oil sealing endoporus by small end, make oil-sealing sleeve on cylinder body, again the cylindrical hole on the cylinder body is enclosed within the rotating shaft; With strength oil sealing is inwardly pushed and installed; After oil sealing installs, cylindrical body to be extracted, oil sealing just is sleeved in the rotating shaft very naturally.This oil sealing erecting device makes the installation of oil sealing fairly simple; But in use; Also there are many deficiencies: because the columnar portion of cylindrical body and the tapered portion of cylindrical body are integral type; If it is longer apart from axle head that the position of oil sealing is installed on the axle, after the cylindrical body of this oil sealing erecting device was enclosed within on the axle so, the oil sealing on the cylindrical body can't arrive the installation site; The weight of this oil sealing erecting device is heavier in addition, in the process of on axle, overlapping, requires great effort very much; Moreover, because cylindrical body to the tension force of oil sealing endoporus and the hand thrust to oil sealing, makes the outer surface of the oil sealing after the installation produce bending or fold is uneven, influence the installation quality of oil sealing.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provide a kind of can be on axle any position fit oil sealing be installed, and installation quality is good, the oil sealing erector of rapid operation.
The technical solution of the utility model is; A kind of oil sealing erector with following structure is provided: it comprises the cylindrical body and the lead of hollow; One end of said cylindrical body is provided with the installation portion that fuel feeding envelope endoporus is inserted in; Said lead comprises connecting portion and guide part, and the centre bore of the installation portion of described connecting portion and cylindrical body flexibly connects, and described guide part is the big truncated cone-shaped in little the inner, outer end.
After adopting above structure, the utility model oil sealing erector compared with prior art has the following advantages: when oil sealing is installed; Earlier the connecting portion of lead is packed in the centre bore of installation portion of cylindrical body; The guide part of the interior aperture truncated cone-shaped of the oil sealing after the preheating is enclosed within on the installation portion of cylindrical body, takes off lead then, with the cylindrical body that oil sealing is housed through its inner hole sleeve in rotating shaft; And make the position of oil sealing near charge of oil envelope in the rotating shaft; Then with hand from the lining to the extrapolation oil sealing, oil sealing is installed in the rotating shaft, cylindrical body taken out down from the rotating shaft at last and gets final product; The lead of this oil sealing erector and cylindrical body flexibly connect, so this oil sealing erector can install oil sealing in the optional position of axle after taking off lead, and rapid operation when installing.
As a kind of improvement; It also comprises oil sealing shaping sleeve; The endoporus aperture of said oil sealing shaping sleeve the inner is more than or equal to the external diameter of oil sealing, and said oil sealing shaping sleeve is provided with the wiring hole that is connected with external power supply, and oil sealing shaping sleeve inner face is provided with a plurality of peep poles spaced apart.Because when oil sealing was installed, the cylindrical body that is with oil sealing was to the tension force of oil sealing endoporus and the hand thrust to oil sealing, make the outer surface that is installed in the oil sealing in the rotating shaft produce bending or fold is uneven; This moment with oil sealing shaping jacket casing in rotating shaft; And the inner hole sleeve that makes oil sealing shaping sleeve is on the oil sealing of rotating shaft; Oil sealing shaping sleeve energising back heating, the oil sealing shaping sleeve lining of heating scalds the outer surface of pressing oil sealing, makes the outer surface of oil sealing smooth; When scalding pressure oil sealing outer surface, can be clear that from peep pole whether the outer surface of oil sealing is flattened by boiling hot.
