Abstract
The invention relates to an oil draining block and oil sucking hydraulic circuit combination device for a sliding block hydrostatic guide rail and belongs to a dedicated matched part for a sliding block hydrostatic guide rail. Returning oil of a traditional hydrostatic guide rail is discharged into an oil returning groove of a lathe, is in direct contact with the air and the environment is easily polluted by the oil, the oil is polluted by the impurities. An oil draining block and an oil sucking hydraulic circuit are designed aiming at the technical problem. The oil draining block is matched with a sliding block of the hydrostatic guide rail in terms of shape. One oil returning hole is communicated with the oil returning groove of the hydrostatic guide rail, the returning oil of the hydrostatic guide rail is discharged out through the hole. The oil sucking hydraulic circuit exhausts the oil into an oil tank. In the hydraulic circuit, the exhausting amount of an oil sucking pump is larger than the use amount of the hydrostatic guide rail. Thus, the negative pressure discharging is performed. The stability of the hydrostatic guide rail is improved, as a cooling device is arranged in the hydraulic circuit, the temperature of oil for hydrostatic pressure can be controlled, the temperature of the oil for hydrostatic pressure is kept stable and therefore, the bearing capacity and the rigidity of the hydrostatic guide rail are kept stable.
Description
Technical field
The present invention relates to the auxiliary component of slide block type hydrostatic slideway, especially relevant with oil suction hydraulic circuit combination unit with the draining piece with the slide block type hydrostatic slideway.
Background technology
Traditional hydrostatic slideway oil return is all to contact with atmosphere to the discharge of lathe oil-recovery tank, this kind mode is called the open type discharge, blowdown presssure is zero, because oil contacts with atmosphere, easily produce the oil pollution environment, impurity is easily sneaked in fluid and is caused oil itself to pollute, and affects oily service life, the present invention is directed to above-mentioned technical problem and with draining piece and oil suction hydraulic circuit, changes traditional open circuit and change the enclosed oil return system into.
Summary of the invention
The present invention is directed to the problems referred to above, designed the slide block type hydrostatic slideway with draining piece and oil suction hydraulic circuit, solve to have and pollute and the life of oil problem.
For addressing the above problem, the present invention has designed the draining piece consistent with slide block type hydrostatic slideway slide block profile, with slide block type, installs to link into an integrated entity to form the unified moulding of slide block type hydrostatic slideway.
The draining hole is connected with the oil suction hydraulic circuit with pipe joint; hydraulic circuit is comprised of low pressure constant displacement pump, choke valve, check valve, filter, cooler; the metered flow of requirement constant displacement pump is greater than the use amount of slide block type hydrostatic slideway; the cooling power of cooler is greater than the caloric value of hydrostatic slideway; guarantee that fluid is cooled in time; improve the stability of hydrostatic slideway, the protection loop of choke valve and check valve formation pump simultaneously, prevent that constant displacement pump from being inhaled sky.
The accompanying drawing explanation:
Fig. 1 is the stereoscopic three-dimensional figure of draining piece of the present invention.
Fig. 2 is draining piece of the present invention and oil suction hydraulic loop structure schematic diagram
Fig. 3 is draining piece and slide block type hydrostatic slideway scheme of installation in the present invention
The specific embodiment
As shown in Figure 2, the pressure oil flowed out from static pressure slide block pressure oil pocket enters respectively draining piece 1, focuses in collection hole 16, then by draining hole 3, is connected with the oil suction hydraulic circuit.Oil return is through the effect of oil scavenge pump 10, and through filter 14, cooler 15 flows back to fuel tank.In order to control return pressure, overflow valve 13 regulation and control are arranged.In order to protect low pressure constant displacement pump 10 not find time, installed choke valve 11 additional, check valve 12, purpose is the service life that extends low pressure constant displacement pump 10.This package unit has formed the secondary enclosed of hydrostatic slideway and has reclaimed hydraulic oil system.
As Figure 1-3, draining piece 1 is tightened on static pressure slide block 18 by screw hole 4,5,6,7,8,9 with screw, profile is consistent with guide rail 17, easy for installation, is communicated with the oil suction hydraulic circuit with pipe joint, can test or use.
