Abstract
The utility model discloses a spindle box lifting balancing device which comprises oil cylinders and screw rod lifting devices connected between stand columns and a spindle box. Cylinder bodies of one set of oil cylinders are connected with the spindle box, cylinder bodies of the other set of oil cylinders are connected with the stand columns, piston rods of the two sets of oil cylinders are opposite and are fixedly connected through oil cylinder connecting plates, and an oil inlet of each oil cylinder is connected with a nitrogen bottle containing hydraulic oil through a high-pressure oil pipe. The spindle box lifting balancing device is good in balancing effect, the spindle box can stably move, performance is stable, and production efficiency is improved.
Description
Technical field
The utility model belongs to the machine tool technology field, especially relates to a kind of main spindle box lifting balance device.
Background technology
The general solid casting that adopts of the counter weight device of lathe headstock is placed in the column chamber, by steel wire rope or chain, the pulley assembly through the column top is connected with main spindle box, steel wire rope or chain very easily fracture after operation a period of time in this device, thereby cause the accident, solid casting is also wasted mass energy and resource simultaneously.After adopting the nitrogen balance system, situation makes moderate progress, but existing market is sold and only limited to the little lathe of main spindle box lifting travel, otherwise, will maybe can't install or take large quantity space because of the long complete machine that stretches out of the oil cylinder in balance sysmte, give and produce and use and make troubles.
Summary of the invention
The purpose of this utility model is: provide that a kind of main spindle box moves steadily, the main spindle box lifting balance device of good balance effect.
The technical solution of the utility model is: comprise the oil cylinder and the screw lifting device that are connected between column and main spindle box, oil cylinder comprises two group oil cylinders up and down that are oppositely arranged, the cylinder body of one group oil cylinder is connected with main spindle box, the cylinder body of another group oil cylinder is connected with column, relatively and be fixed together by the oil cylinder connecting plate, the oil-in of every oil cylinder is connected with the nitrogen cylinder that hydraulic oil is housed by high-pressure oil pipe the piston rod of two group oil cylinders.
Further, every group oil cylinder comprises one or two oil cylinders.
The beneficial effects of the utility model are: the utility model changes oil cylinder into stack and uses, stretch out successively and replace whole long-cylinder with branched oil cylinder, when lifting motor drives main spindle box and moves up by leading screw, nitrogen pressure in nitrogen cylinder is pressed into branched oil cylinder by hydraulic oil, two group oil cylinders are regained successively, the weight of piston rod supports main shaft case balancing main shaft case; When lifting motor drives main spindle box and moves down by leading screw, the piston rod of two group oil cylinders stretches out successively, and the hydraulic oil of branched oil cylinder is pressed in nitrogen cylinder by high-pressure oil pipe again, and main spindle box arrives processing needs position, the weight of balancing main shaft case, alleviated the power of lifting motor.The utility model has solved the large route problem of main spindle box by the nitrogen balance system, the main spindle box shift motion is strengthened, greatly reduce the processing technology of oil cylinder in lathe volume and simplification balance sysmte, long-cylinder can be changed into to the short oil cylinder, reduce difficulty of processing, saving resource and the energy, good balance effect, main spindle box moves steadily, and stable performance, improved production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The layout drawing that Fig. 2 is oil cylinder in the utility model.
The specific embodiment
From the layout drawing of structural representation of the present utility model shown in Fig. 1 and Fig. 2 oil cylinder, can find out, the utility model comprises column 4, main spindle box 5, is connected to two group oil cylinders, screw lifting device and nitrogen cylinder 6 between column and main spindle box, screw lifting device comprises lifting motor 1 and ball-screw 3, ball-screw 3 is connected with main spindle box 5 by nut, bearing block 2 support and connection are passed through on column 4 in leading screw 3 two ends, lifting motor 1 is arranged on column 4 and is connected with ball-screw 3 one ends, and lifting motor 1 drives main spindle box 5 by leading screw 3 and moves up and down.Oil cylinder comprises two group oil cylinders up and down that are oppositely arranged, and the cylinder body II 10 of a group oil cylinder II is connected with main spindle box, and upwards, main spindle box is connected and fixed place 13 to piston rod II 11; The cylinder body I 7 of another group oil cylinder I is connected with column 4, and piston rod I 8 is downward, and the piston rod that column is connected and fixed place's 12, two group oil cylinders relatively and be fixed together by oil cylinder connecting plate 14.Every group oil cylinder comprises one or two oil cylinders, configures as required every group oil cylinder quantity, one of the oil cylinder I of stretching out downwards as piston rod I 8, two of the oil cylinder II that piston rod II 11 protrudes upward, two the symmetrical oil cylinder I of oil cylinder II both sides.Certainly, according to actual requirement, the oil cylinder of every group oil cylinder configurable 3 or greater number.Because the piston rod of upper and lower two group oil cylinders is fixed together by oil cylinder connecting plate 14, two group oil cylinders stacks are used, branched oil cylinder stretches out piston rod supports main shaft case successively, the main spindle box shift motion is strengthened, simultaneously, the long-cylinder that tradition can be used changes the short oil cylinder into, reduces difficulty of processing.The oil-in 9 of every oil cylinder is positioned at the oil cylinder link, and oil-in 9 is connected with nitrogen cylinder 6 by high-pressure oil pipe, is filled with the nitrogen of appropriate hydraulic oil and appropriate pressure in nitrogen cylinder 6.
Operation principle of the present utility model is: when lifting motor 1 moves up by leading screw 3 drive main spindle boxes 5, the nitrogen pressures in nitrogen cylinder 6 are pressed into branched oil cylinder by hydraulic oil, and two group oil cylinders are regained successively, piston rod supports main shaft case, the weight of balancing main shaft case; When lifting motor 1 moves down by leading screw 3 drive main spindle boxes 5, the piston rod of two group oil cylinders stretches out successively, and the hydraulic oil of branched oil cylinder is pressed in nitrogen cylinder by high-pressure oil pipe again, and main spindle box 5 arrives processing needs position; Use and so forth.
