Abstract
The invention discloses a spindle box lifting balance device. The spindle box lifting balance device comprises oil cylinders which are connected between a stand column and a spindle box and a leading screw lifting device, wherein a cylinder body of one set of oil cylinder is connected with the spindle box, a cylinder body of the other set of oil cylinder is connected with the stand column, piston rods of the two sets of oil cylinders are opposite to each other and fixedly connected together through an oil cylinder connecting plate, and an oil inlet of each oil cylinder is connected with a nitrogen gas cylinder with hydraulic oil through a high-pressure oil pipe. The spindle box lifting balance device is good in balance effect, the spindle box is smooth and steady in moving, and stable in performance, and production efficiency is improved.
Description
Technical field
The invention belongs to the machine tool technology field, especially relate 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 places in the column chamber, pulley assembly through the column top is connected with main spindle box by steel wire rope or chain, steel wire rope or chain very easily rupture after moving 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 the balance sysmte, make troubles for production and use.
Summary of the invention
The objective of the invention is: provide that a kind of main spindle box moves steadily, the main spindle box lifting balance device of good balance effect.
Technical scheme of the present invention is: comprise the oil cylinder and the screw lifting device that are connected between column and the main spindle box, oil cylinder comprises up and down two group oil cylinders 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, the piston rod of two group oil cylinders is fixed together relatively and by the oil cylinder connecting plate, and the oil-in of every oil cylinder is connected with the nitrogen cylinder that hydraulic oil is housed by high-pressure oil pipe.
Further, every group oil cylinder comprises one or two oil cylinders.
The invention has the beneficial effects as follows: the present invention changes oil cylinder into stack and uses, stretch out successively whole long-cylinder of replacement with branched oil cylinder, when lifting motor moves up by leading screw drive main spindle box, nitrogen pressure in the nitrogen cylinder is pressed into branched oil cylinder with 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 moves down by leading screw drive main spindle box, the piston rod of two group oil cylinders stretches out successively, and the hydraulic oil of branched oil cylinder is pressed in the nitrogen cylinder by high-pressure oil pipe again, and main spindle box arrives processing needs the position, the weight of balancing main shaft case has alleviated the power of lifting motor.The present invention has solved the large route problem of main spindle box with the nitrogen balance system, the main spindle box shift motion is strengthened, greatly reduce the processing technology of oil cylinder in lathe volume and the simplification balance sysmte, long-cylinder can be changed into the short oil cylinder, reduce difficulty of processing, saving resource and the energy, good balance effect, main spindle box moves steadily, and stable performance has improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the layout drawing of oil cylinder among the present invention.
The specific embodiment
Can find out from the layout drawing of structural representation of the present invention shown in Figure 1 and Fig. 2 oil cylinder, the present invention includes column 4, main spindle box 5, be connected to two group oil cylinders, screw lifting device and nitrogen cylinder 6 between column and the 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 installed on the 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 up and down two group oil cylinders that are oppositely arranged, and the cylinder body II 10 of a group oil cylinder II is connected with main spindle box, and piston rod II 11 makes progress, and main spindle box is connected and fixed place 13; 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 is fixed together relatively and by oil cylinder connecting plate 14.Every group oil cylinder comprises one or two oil cylinders, disposes as required every group oil cylinder quantity, one of the oil cylinder I of stretching out downwards such 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 two group oil cylinders is fixed together by oil cylinder connecting plate 14 up and down, the stack of two group oil cylinders is used, branched oil cylinder stretches out piston rod supports main shaft case successively, the main spindle box shift motion is strengthened, simultaneously, can change the long-cylinder that tradition is used into the short oil cylinder, reduce 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 an amount of hydraulic oil and an amount of pressure in the nitrogen cylinder 6.
Operation principle of the present invention is: when lifting motor 1 moved up by leading screw 3 drive main spindle boxes 5, the nitrogen pressures in the nitrogen cylinder 6 were pressed into branched oil cylinder with 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 drove main spindle boxes 5 and moves down by leading screw 3, the piston rod of two group oil cylinders stretched out successively, and the hydraulic oil of branched oil cylinder is pressed in the nitrogen cylinder by high-pressure oil pipe again, and main spindle box 5 arrives processing needs the position; Use and so forth.
