Description
Technical field:
The utility model relates to a kind of hydraulic pressure installation, especially a kind of hydraulic pressure installation that is used for the main shaft balance on vertical machine.
Background technique:
Because the requirement of machining accuracy, the main shaft of vertical machine all is furnished with Equilibrator, is generally mechanical counterweight now, comes balancing main shaft with the weight of constant weight, heaviness not only, and also the machining accuracy of lathe is not high yet.
Summary of the invention:
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of precision high hydraulic balance device.
For achieving the above object, the technical solution adopted in the utility model is: machine tool chief axis balanced hydraulic device comprises fuel tank (9) and is fixed on motor (2), Variable plunger pump (1), one-way valve (3), three-way pressure reducing valve (5), accumulator (7), filter (10) on the fuel tank (9).Each inter-module all connects by transport pipe.Motor (2) is connected with Variable plunger pump (1).One-way valve (3) one ends are connected with Variable plunger pump (1), and the other end is connected with three-way pressure reducing valve (5).The oil outlet of three-way pressure reducing valve (5) is connected on the oil cylinder, is provided with accumulator (7) between three-way pressure reducing valve (5) and oil cylinder.The flow-off of three-way pressure reducing valve (5) is connected in the fuel tank (9) through filter (10).Pressure gauge (6-1) is connected with Variable plunger pump (1).Pressure gauge (6-2) links to each other with three-way pressure reducing valve (5).On fuel tank (9), also be provided with relief valve (4), electric contact thermometer (13), show level meter (14), air-strainer (15) and air-cooled cooler (11).
The utility model modern design, simple in structure, be easy to control, accurately the balance machine tool chief axis.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the right elevation of Fig. 1.
Fig. 4 is a fundamental diagram of the present utility model.
Embodiment:
As shown in Figure 1-Figure 3: machine tool chief axis balanced hydraulic device comprises fuel tank 9 and the motor 2, Variable plunger pump 1, one-way valve 3, three-way pressure reducing valve 5, accumulator 7, the filter 10 that are fixed on the fuel tank 9.Each inter-module all connects by transport pipe.Motor 2 is connected with Variable plunger pump 1.One-way valve 3 one ends are connected with Variable plunger pump 1, and the other end is connected with three-way pressure reducing valve 5.The oil outlet of three-way pressure reducing valve 5 is connected on the oil cylinder, is provided with accumulator 7 between three-way pressure reducing valve 5 and oil cylinder.The flow-off of three-way pressure reducing valve 5 is connected in the fuel tank 9 through filter 10.Pressure gauge 6-1 is connected with Variable plunger pump 1.Pressure gauge 6-2 links to each other with three-way pressure reducing valve 5.On fuel tank 9, also be provided with relief valve 4, electric contact thermometer 13, show level meter 14, air-strainer 15 and air-cooled cooler 11.
Working principle:
As shown in Figure 4: motor 2 starts, and drives Variable plunger pump 1, and fluid is sucked from the pump inlet port, discharges from oil outlet, and can form certain pressure, and this pressure can show by pressure gauge 6-1.Pressure oil enters three-way pressure reducing valve 5 through one-way valve 3.The secondary pressure of three-way pressure reducing valve 5 is determined according to main shaft weight, also can adjust by the electric power difference of spindle motor rise and fall, for improving performance, reduces pressure pulsation simultaneously, has set up accumulator 7.When main shaft rose, pressure oil entered main shaft balancing cylinder 8 through three-way pressure reducing valve 5 decompressions, guarantees oil cylinder 8 cavity of resorption constant pressures.When main shaft descends, pressure oil in the main shaft balancing cylinder 8 is discharged through the flow-off of three-way pressure reducing valve 5, through filter 10 oil sump tanks 9, pressure was basic identical when this moment, oil pressure relief and main shaft rose, thereby guarantee no matter main shaft rises or descends, and can obtain identical exerting oneself from main shaft balancing cylinder 8.The secondary pressure of three-way pressure reducing valve 5 is shown by pressure gauge 6-2.The relief valve 4 main safety effects that rise are used to protect oil pump.The deep fat that Variable plunger pump 1 drain tap is discharged flows back to fuel tank 9 through air-cooled cooler 11.The electric contact thermometer 13 that shows the oil temperature is arranged in this device in addition, show the level meter 14 of liquid level, and the air-strainer 15 that is used for the oiling exhaust.
