Description
Technical field
The present invention relates to a kind of oil sealing assembly tool, especially relate to a kind of deep hole inner oil seal assembly tool.
Background technology
In mechanical assembly technology, often need in a deep hole, assemble oil sealing, sometimes, operating personnel beat with simple tools such as pole, hammers, to finish installation after putting it into by hand again.But this mounting means easily causes its installation inaccurate on the one hand, occurs tilting, on the other hand also easily to the injury of oil sealing own.Existing oil sealing assembly tool is a lot, be that the Chinese patent of CN202985466U discloses a kind of oil sealing erecting tools such as publication number, comprise oil sealing erecting tools body, be characterized in: described oil sealing erecting tools body is drum, cylindric erecting tools body upper end is hammering section, the centre is the grip part, and the lower end is the oil sealing contact site, and described oil sealing contact site lower surface is smooth smooth annular.The subject matter of the disclosure technology is, its in use, the location does not have in the folding process, inclination easily appears in oil sealing and instrument itself.Publication number is that the Chinese patent of CN202292589U discloses a kind of oil seal installation tool for engine, comprise positioning plate in the formation, key seat, push rod and bolt, described positioning plate shape triangular in shape, the key seat of half fixed installation thereon, described key seat is the notch cuttype tube-in-tube structure, on its bottom surface and sidewall, arrange respectively large, the minor thread hole, described push rod is the multidiameter structure, its small diameter portion periphery is provided with the strip groove, small diameter portion is sleeved on key seat inside, the major diameter section axial arranges the centre bore equipped with the balance shaft of engine afterbody, and described bolt and major thread hole, key seat bottom surface are equipped, and its tail end contacts on push rod minor diameter end face.This patent is located by positioning plate, can play under given conditions the effect of accurate location, but because its prerequisite that reaches accurate location has following 2 points: 1, have on the workpiece one reliably, accurately below, and be provided with two pin-and-holes corresponding with alignment pin on this plane; 2, the location between location-plate and alignment pin and location-plate and the key seat is very accurate.And in fact, general casing is foundry goods, and its surperficial required precision is not high, be difficult to find on its surface one reliably, plane of orientation accurately.And to realize that location-plate, alignment pin and key seat position are accurate, its manufacturing cost is very high.Therefore, this patent is difficult to realize technically.
Summary of the invention
The present invention mainly is that the existing location of solution prior art trouble, cost are high; locate the technical problems such as inaccurate; provide a kind of simple in structure, easy to operate, the location is reliable, cost is low; can when being installed, oil sealing reach effective location; on the one hand oil sealing can be installed accurately and conveniently, on the other hand also can oil sealing in installation process, play the oil sealing Special tool for assembling of reliable protective effect.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of oil sealing Special tool for assembling, it is characterized in that it comprises the slip last item, the slip last item is arranged with the positioning sleeve that can slide at this last item that slides outward, positioning sleeve is made of end face positioning tube and axial location cylinder, the lower end of described slip last item is provided with for the fixing oil seal seat of oil sealing, the outside of this oil seal seat is provided with several equally distributed oil sealing fixed bars, this oil sealing fixed bar is threaded with described oil seal seat, and the upper end of described positioning sleeve sliding stroke is provided with the positioning sleeve position-limit mechanism.The present invention mainly is applicable to the operation at deep hole bottom assembling oil sealing, in use, oil sealing is located at the oil seal seat bottom, fix by the oil sealing fixed bar, size according to oil sealing, can adjust the length that the oil sealing fixed bar stretches out oil seal seat, the degree of depth according to deep hole, adjust the position of positioning sleeve position-limit mechanism, to set the position of the top side that positioning sleeve can move to, oil seal seat is extend in the deep hole, the axial location cylinder of positioning sleeve is located at the deep hole port (need selects the positioning sleeve of the axial location cylinder of different sizes according to the deep holes of different sizes, axial location cylinder deep hole port inboard suitable, the end face positioning tube is fitted on the end face of deep hole), then move down the slip last item, positioning sleeve is fixing different, slip last item relative positioning cover is mobile, until oil sealing is pressed onto the position.In press-fiting process, the slip last item axially by positioning sleeve location, can not be offset, not only oil sealing is played a very good protection, simultaneously also so that the installation of oil sealing is more accurate, reliably.Because general deep hole is that endoporus or end face all need to accomplish higher precision, so when it positioned relatively, degree of accuracy meeting was very high, and the cost compare the during location is low, and comparison is convenient.
As preferably, described positioning sleeve position-limit mechanism comprises that is located at a slip last item outside, and the stop nut that is threaded with the slip last item, and the upside of stop nut is provided with the locking nut that is threaded with the slip last item side by side with stop nut.Regulate according to the degree of depth of deep hole and the installation site rotary spacing nut of oil sealing, thus the top dead-centre of adjustment positioning sleeve.Stop nut and locking nut consist of the double nut retaining mechanism.
As preferably, described oil seal seat is provided with the cavity of open lower side, and the chamber wall is provided with and described fixed bar corresponding adaptive tapped through hole one by one, and described fixed bar is screw rod, the head of this screw rod inwardly, afterbody is outwardly.From the inboard of chamber wall instrument rotating screw bolt, adjust the extension elongation of fixed bar, this length determines according to the internal diameter size of oil sealing.In use, each fixed bar withstands on respectively the inboard of oil sealing, and oil sealing is played interim fixation.
As preferably, described screw rod is provided with governor motion, this governor motion comprises the upper end of passing the slip last item and the adjusting rotating shaft that is rotationally connected with slip last item upper end, the lower end of this adjusting rotating shaft is provided with large angular wheel, and the end of described screw rod is provided with the bevel pinion suitable with described large angular wheel.Regulate rotating shaft and rotate and to drive bolt rotary by the structure of large bevel pinion, the tail end of screw rod (being fixed bar) (namely stretching out an end in the oil seal seat outside) while indentation or stretch out.Scheme can be loaded onto before press-fiting in the process of oil seal seat in the charge of oil encapsulation, selects the indentation screw rod, oil sealing is installed to the position of screw rod, screw rod is stretched out again, and fixes on purpose on the screw rod to reach the charge of oil sealing.Its usefulness is: can prevent that 1, oil sealing from damaging in loading onto the process of oil seal seat; 2, after oil sealing installs to the fixed position, can contract again by first loading screw, take out again the slip last item, convenient, fast, not damaged; 3, this mechanism can be so that the present invention be respectively applied to press-fiting of different oil sealings.
