Description
Technical field
The present invention relates to a kind of upright post self-lubricating structure of oil hydraulic press, particularly a kind of novel upright post self-lubricating structure of oil hydraulic press.Belong to the oil pressure field of mechanical technique.
Background technology
The column of column hydraulic press is the strength member of hydraulic press, it is not only the support of hydraulic press total, also be the main bearing part that hydraulic press holds lotus simultaneously, it also is the guiding parts of hydraulic press slide block in addition, slide block moves up and down on column by being installed in its sliding bearing on one's body, so column and with Upright post base mutually the motion sliding bearing wearing and tearing and cause the hydraulic press operating accuracy to descend, thereby might cause the generation of hydraulic press work abnormal conditions.The main cause that causes hydraulic press column and sliding bearing inordinate wear is an insufficient lubrication and because due to hard sharp foreign matter falls between column and the sliding bearing kinematic pair, solution for this kind problem, the way of main prevention is exactly periodic maintenance and oily way at present, but because the artificial carelessness and the influence of other factors are arranged sometimes, often can not accomplish lubricated timely and effectively and maintenance, so equipment breakdown still usually takes place.
Summary of the invention
The objective of the invention is to: a kind of novel upright post self-lubricating structure of oil hydraulic press is provided, overcomes between the column and sliding bearing of existing hydraulic press, owing to structural reason, the defective that is easy to wear and tear that exists between the column of hydraulic press and the sliding bearing.
Solving the technical scheme that its technical problem adopts is: a kind of novel upright post self-lubricating structure of oil hydraulic press, and it is by gland hold-down screw, gland, dust-proof seal ring, bearing holder (housing, cover), sliding bearing, fuel reserve tank, wool felt, sealing ring, pump nozzle, slide block, guide pillars etc. are formed.The centre of described bearing holder (housing, cover) is mounted with sliding bearing, guide pillar is installed in the centre of sliding bearing, the relation that both formation are slidingly matched, adopt the installation relation of secure fit between bearing holder (housing, cover) and the slide block, the free degree of not having relative motion between the two, make external screw thread above the cylindrical of described bearing holder (housing, cover) lower end, described fuel reserve tank is the container of round barrel shape, its bottom has through hole, the slightly larger in diameter of through hole is in the diameter of guide pillar, the upper oral part of described fuel reserve tank is made internal thread, the size of its internal thread is identical with external screw thread on the cylindrical of bearing holder (housing, cover) lower end, fuel reserve tank links together by the internal thread at its position suitable for reading and the external screw thread of bearing holder (housing, cover) lower end, the wool felt (also can be cotton wool felt etc.) that its inner filling is an amount of, with the sealing ring sealing, on the cylindrical side of described fuel reserve tank pump nozzle is installed between the bottom through-hole of fuel reserve tank and the guide pillar.Be convenient between guide pillar and sliding bearing, form lubricated in order to make fluid, have the spiral oil groove of suitable pitch on the surface of the interior circle of sliding bearing, suitable tapering is made in the upper end of described sliding bearing, form the space of V-arrangement between its outer cone and the bearing holder (housing, cover), the space of this V-arrangement, can hold between the foreign matter brought into from the external world or sliding bearing and the guide pillar wearing and tearing mutually and produce fall to taking off thing.At the upper oral part of sliding bearing and bearing holder (housing, cover), gland also is set, gland with gland screw with gland be fixed on bearing holder (housing, cover) above, seal with sealing ring between gland and the guide pillar.
In above-mentioned structure, in fuel tank, inject suitable lubricating oil by pump nozzle, when then doing relative motion between sliding bearing and guide pillar, oil stored in the fuel tank is just by spiral oil groove, to whole sliding bearing the guide pillar face of process be lubricated.
Beneficial effect: since be provided with in the bottom of bearing holder (housing, cover) can oil storage fuel tank, and between fuel tank and the guide pillar, and between the top oral area of bearing holder (housing, cover) and the guide pillar reliable sealing is set all, so not only have dustproof, anti-foreign matter falls between the sliding surface, can also form good lubricating simultaneously between the sliding surface.Thereby the improper wearing and tearing that can effectively avoid between the sliding surface being caused prolong hydraulic press service life.
