Description
Technical field
The utility model belongs to hydraulic system pressure retaining technology field, is specifically related to a kind of Horizontal iron ball lapping machine hydraulic system.
Background technique
Horizontal iron ball lapping machine is last one manufacturing procedure in steel ball processing, so very high to the stability requirement of equipment and pressure.Its pressure is that the hydraulic pressure used controls, and conventional Stress control principle as shown in Figure 1, uses accumulator pressurize.Under this hydraulic system normal operation, metering pump is shut down, and only has and just start when pressure is less than regulated pressure, uses this pressurize mode can make pressure transient, pressure surge greatly, thus can affect the precision of processing steel ball.
Summary of the invention
The technical problem that the utility model solves there is provided the effective and Horizontal iron ball lapping machine hydraulic system that energy consumption is lower of a kind of pressure stability, pressurize.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: Horizontal iron ball lapping machine hydraulic system, it is characterized in that between oil hydraulic cylinder and fuel tank, forming circulation loop by two oil circuits, on an oil circuit wherein by fuel tank to oil hydraulic cylinder rodless cavity between be provided with oil purifier, limit pressure type variable pump and solenoid directional control valve successively, oil circuit between solenoid directional control valve and oil hydraulic cylinder is provided with pressure gauge, the middle part of another oil circuit is connected with solenoid directional control valve, and two ends are connected with the rod chamber of oil hydraulic cylinder with fuel tank respectively.
The utility model compared with prior art has following beneficial effect: utilize the Horizontal iron ball lapping machine of this hydraulic system can ensure stable pressure, and then produces the higher steel ball of precision.
Accompanying drawing explanation
Fig. 1 is the long splice composition of Horizontal iron ball lapping machine hydraulic system in prior art, and Fig. 2 is long splice composition of the present utility model.
Drawing illustrates: 1, fuel tank, 2, oil hydraulic cylinder, 3, oil purifier, 4, metering pump, 5, solenoid directional control valve, 6, Pilot operated check valve, 7, electromagnetic relief valve, 8, pressure gauge, 9, accumulator, 10, oil circuit control, 11, limit pressure type variable pump.
Embodiment
Describe particular content of the present utility model by reference to the accompanying drawings in detail.
As shown in Figure 1, Horizontal iron ball lapping machine hydraulic system of the prior art is made up of two symmetrical oil circuits, an oil circuit is wherein provided with oil purifier 3 successively by between the rodless cavity of fuel tank 1 to oil hydraulic cylinder 2, metering pump 4, solenoid directional control valve 5 and Pilot operated check valve 6, electromagnetic relief valve 7 is parallel on metering pump 4, for the pressure of regulator solution pressing system, oil circuit between Pilot operated check valve 6 and solenoid directional control valve 5 is respectively equipped with pressure gauge 8 and accumulator 9, the middle part of another oil circuit is connected with solenoid directional control valve 5, two ends are connected with the rod chamber of fuel tank 1 with oil hydraulic cylinder 2 respectively, oil circuit between oil hydraulic cylinder 2 with solenoid directional control valve 5 is connected with Pilot operated check valve 6 by oil circuit control 10.
As shown in Figure 2, Horizontal iron ball lapping machine hydraulic system of the present utility model forms circulation loop by two oil circuits between oil hydraulic cylinder 1 and fuel tank 2, oil purifier 3, limit pressure type variable pump 11 and solenoid directional control valve 5 is provided with successively between rodless cavity by fuel tank 1 to oil hydraulic cylinder 2 on an oil circuit wherein, oil circuit between solenoid directional control valve 5 and oil hydraulic cylinder 2 is provided with pressure gauge 8, the middle part of another oil circuit is connected with solenoid directional control valve 5, and two ends are connected with the rod chamber of fuel tank 1 with oil hydraulic cylinder 2 respectively.
When the left position work of solenoid directional control valve, the oil that limit pressure type variable pump is up to arrives the rodless cavity of oil hydraulic cylinder through solenoid directional control valve, thus push piston and move right, when the right position work of solenoid directional control valve, the oil that limit pressure type variable pump is got enters the rod chamber of oil hydraulic cylinder through the right position of solenoid directional control valve, thus push piston and be moved to the left, the left and right bit interleaving of solenoid directional control valve works, make piston can realize moving back and forth, when the meta work of solenoid directional control valve, the piston of oil hydraulic cylinder can be parked in any position.The hydraulic principle of this system utilizes a limit pressure type variable pump to keep pressure, equipment driven by motor limit pressure type variable pump in the process of work is always in running order, limit pressure type variable pump is always fuel-displaced endlessly before hydraulic system reaches adjusted pressure, when pressure reaches the pressure that hydraulic system adjusts, the oil that limit pressure type variable pump goes out is only for hydraulic system leakage, when hydraulic system does not occur to reveal, limit pressure type variable pump dallies, do not do work, so there is no energy waste, and because limit pressure type variable pump is always in running order, and then can the pressure of stable output.
More than show and describe basic principle of the present utility model; major character and advantage; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
