Abstract
The utility model discloses a novel vertical type lathe power-off static pressure protective device. One end of a power shaft is connected to a gear pump through a shaft coupling, and the middle of the power shaft is connected to a flywheel. The power shafts at two sides of the flywheel are respectively connected to a small retainer ring, an inner ring of a bearing and a circular nut in order. An outer ring of the bearing is connected to an inner hole of a bearing pedestal, and an inner end face of the bearing pedestal is connected to an inner end cap. An inner hole of the inner end cap is connected to an external surface of the retainer ring through a sealing ring. A flange inner hole connected to an outer end of the bearing pedestal is connected to a power shaft through a gland and a revolution sealing ring. The flange is connected to an outer ring of the bearing through a large retainer ring. The bearing pedestal is fixed to a lower seat and an oil box wall. An oil filter is connected to the gear pump through an oil pipe, and the gear pump is connected to an oil outlet pipe and is fixed to a pump support connected to the flange. The novel vertical type lathe power-off static pressure protective device is advantageous in that the structure is simple and transmission efficiency is high; when a sudden power-off occurs, oil can still be supplied for a static pressure guide rail of a machine tool by means of the rotatory inertia of the heavy type flywheel for more than 15 seconds, and thereby the possibility of damaging the machine tool guide rail can be completely eliminated.
Description
Technical field
The utility model relates to a kind of protective device, relates in particular to a kind of novel vertical lathe outage static pressure protective device, belongs to the mechanized equipment technical field.
Background technology
Heavy-duty engine lathe such as numerical control vertical lathe was to characteristic development such as high-mechanic, high-speed, high efficiency, high accuracy, high automations in recent years, and the technical performance of lathe and characteristics comprise that aspects such as machine tool structure, Technological adaptability, precision, dependability and pleasant property have largely and improve.Have the ability that a lot of enterprises possess jumboes such as production numerical control movement vertical type lathe and mill-turn now both at home and abroad, our factory has successfully been developed high accuracy double-column vertical milling Vehicle Processing center HDVTM1250 product, the space of country at heavy high accuracy process unit will be filled up, for changing the situation that China's heavy machine tool only captures low-end market, promote the technical value added of homemade lathe, have strategic importance.But following, the power-off protection apparatus of heavy high accuracy process units such as numerical control high accuracy double-column vertical milling Vehicle Processing center becomes a primary difficult problem.
Summary of the invention
In order to address the above problem; the purpose of this utility model is to provide a kind of novel vertical lathe outage static pressure protective device; be to adopt independently hydrostatic slideway fueller; line shaft at this device adds heavy flywheel; can be after outage suddenly, by the inertia rotation of heavy flywheel, still can be lathe hydrostatic slideway fuel feeding more than 15 seconds; can avoid damaging the possibility of hydrostatic slideway fully, improve security and the reliability of lathe work greatly.
The technical solution of the utility model is: novel vertical lathe outage static pressure protective device, and by oil filter, gear pump, pump support, shaft coupling, rotary seal ring, bearing, flywheel, ring flange, round nut, line shaft, following, bearing block, inner end cap, little retainer plate, retainer plate, gland, motor are formed greatly.End at line shaft is connected with motor, is connected with gear pump at the other end by shaft coupling, is connected with flywheel in the centre of line shaft.On the line shaft of flywheel both sides, be connected with interior ring, the round nut of little retainer plate, bearing respectively in turn, the outer shroud of bearing is connected with inner hole of bearing seat, the bearing block inner face is connected with inner end cap, the inner end cap endoporus is connected with the retainer plate outer surface by sealing ring, bearing block outer end flange connecting dish endoporus is connected with line shaft by gland, rotary seal ring, ring flange also is connected with the outer shroud of bearing by big retainer plate, and bearing block is fixed on down on seat and the oil tank wall.Be built-in with oil filter at the fuel tank of forming with oil tank wall by following, oil filter is connected with gear pump by oil pipe, and gear pump also is connected with flowline and is fixed on the pump support that is connected with ring flange.
The beneficial effects of the utility model are: a kind of novel vertical lathe outage static pressure protective device that the utility model provides is a kind of independently hydrostatic slideway fueller; have simple in structure, advantages such as transmission efficiency is high, good reliability; after outage suddenly; the rotatory inertia that still can lean on heavy flywheel is that lathe hydrostatic slideway fuel feeding is more than 15 seconds; can avoid damaging the possibility of machine tool guideway fully, improve security and the reliability of lathe work.Be applicable to various CNC double-column vertical turning ﹠ boring mills, use on the various lathes such as digital control vertical milling and drilling machine, digital control vertical mill teeth machine.
