Description
Technical field
The present invention relates to a kind of closed slip that is applied to the hydrostatic slideway oil return and follow oil-collecting device, be specially adapted to hydrostatic slideway hydraulic oil high-quality non-resistance and reclaim.
Background technology
The oil return of hydrostatic slideway hydraulic oil generally is to transmit hydraulic oil in the oil-recovery tank or directly flow back to oil groove by flexible pipe.The hydrostatic slideway draining needs hydraulic oil under the self gravitation effect, trickling is in oil return apparatus, in the trickling process, do not have resistance to interfere, when hydrostatic slideway will produce the backflow that bending hinders hydraulic oil when hydraulic oil transmits by flexible pipe in the process of motion, cause the hydrostatic slideway can't pressure release, mineralization pressure is poor, derive load, cause the guide rail movement loss of significance, do not reach result of use; If the hydrostatic slideway oil return under the open type state in the efferent tract oil-recovery tank the cleanliness factor of oil-recovery tank can't well be guaranteed, flying chip or the cooling fluid of lathe in working angles all can splash in the unlimited oil circuit, in oil groove, also need like this to increase and filter and oily-water seperating equipment, greatly increased cost.。
Summary of the invention
The object of the present invention is to provide a kind of slip that is applied to the hydrostatic slideway oil return to follow oil-collecting device, this device can be realized in the unresisted inflow oil-containing groove of hydrostatic slideway hydraulic oil in motion process, and can prevent from spattering bits, cooling fluid and other foreign material and enter in the hydraulic oil by the sealing oil-containing groove, and then guaranteed the cleanliness factor of hydraulic oil to have reduced cost.
The technical solution that realizes the object of the invention is: swab case is communicated with the static pressure rail sliding table oil-out by connecing oily transition screw, fix with static pressure rail sliding table, and seal by the seal combination pad, the hydraulic oil of static pressure rail sliding table oil-out is through connecing in the leak free inflow swab case of oily transition screw; The end of thread of petroleum pipeline is fixed on the swab case by the closely-pitched locking nut, seals by combination mat, and the position that petroleum pipeline is designed is lower than the oil-out of hydrostatic slideway, and makes the petroleum pipeline axis be parallel to the hydrostatic slideway axis; The oil-containing groove hold-down screw is fixed on oil-containing groove on the bed piece, the dust-proof seal ring gland is fixed on dust-proof seal ring on the oil-containing groove by the gland hold-down screw, the oil-containing groove loam cake covers on oil-containing groove, the polished rod part of petroleum pipeline stretches in the oil-containing groove by dust-proof seal ring, petroleum pipeline is followed slip when static pressure rail sliding table slides, in the travel range of hydrostatic slideway, the oil outlet end of petroleum pipeline is in the inside of oil-containing groove all the time, realization hydraulic oil in a locking device, makes in hydraulic oil non-resistance, nothing leakage, the pure inflow oil-containing groove always.
The present invention compared with prior art, its remarkable advantage is: in the static pressure rail sliding table running, guarantee hydraulic oil cleanliness factor requirement simultaneously, can non-resistance, leak free hydraulic oil is recycled to oil sump tank, the hydrostatic slideway precision is not exerted an influence.
