Description
Technical field:
This utility model relates to a kind of fluid power system, is applied to twin grinder and two kinds of types of Twp-sided polishing machine
On.
Background technology:
In the conventional art of twin grinder and Twp-sided polishing machine, upper dish is to be risen by pneumatic actuation, decline and grinding
Live, during polishing, workpiece is carried out Stress control.But owing to air has compressible characteristic, when carrying out Stress control,
Pressure oscillation is big, and its precision and stationarity often do not reach the requirement of precise finiss, when carrying out pressure adjustment and change, can make
, there is the phenomenon of fragment in the impact of workpiece in pairs.
Utility model content:
The purpose of this utility model is to provide the fluid power system that a kind of control accuracy is high, operate steadily.
The technical scheme that this utility model is taked for achieving the above object is as follows:
A kind of fluid power system, it is characterised in that: including oil cylinder, oil cylinder passes through pressure transducer and pressure distribution plate phase
Even, pressure distribution plate is connected with some dowel steels, and precision liquid potential source is connected with oil cylinder, and precision liquid potential source oil supply cylinder provides hydraulic pressure,
Control system is connected with pressure transducer, precision liquid potential source respectively, group between pressure transducer, control system, precision liquid potential source
Become a closed-loop control system.
Further it is provided that
Described fluid power system, is applied on twin grinder or Twp-sided polishing machine, and pressure distribution plate passes through dowel steel
Connect top lap or the upper polishing disk of buffing machine of twin grinder.
Described dowel steel is set to 6-12 root.
Described precision liquid potential source be directly drive with buncher oil pump high-accuracy hydraulic power supply or with servo electricity
The hydraulic power system that machine controls.
The beneficial effects of the utility model are as follows:
A kind of fluid power system of the present utility model, is applied on twin grinder and Twp-sided polishing machine, passes through hydraulic pressure
Type of drive controls upper dish in the rising of upper dish, down maneuver and work process and workpiece is applied precision pressure, has good
Servo characteristic, on dish carry out lifting drive while, can grind and polishing process in workpiece provide meet the requirements
Stable grinding and polish pressure, can reduce the impact to workpiece, simultaneously compared with existing Pneumatic drive system, have more
Good precision and stationarity.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is control principle drawing of the present utility model.
Label in figure: 1, oil cylinder；2, pressure transducer；3, pressure distribution plate；4, dowel steel；5, top lap；6, control
System；7, precision liquid potential source.
Detailed description of the invention:
In embodiment as shown in Figure 1 and Figure 2, a kind of fluid power system of the present utility model, it is applied to twin grinding
Machine, including oil cylinder 1, oil cylinder 1 is connected with pressure distribution plate 3 by pressure transducer 2, and pressure distribution plate 3 is by some dowel steels 4
Connecting the top lap 5 of twin grinder, precision liquid potential source 7 is connected with oil cylinder 1, and precision liquid potential source 7 provides hydraulic pressure to oil cylinder 1,
Control system 6 is connected with pressure transducer 2, precision liquid potential source 7 respectively, pressure transducer 2, control system 6, precision liquid potential source 7
Between form a closed-loop control system.
Described dowel steel 4 is set to 6-12 root.
Described precision liquid potential source 7 is directly to drive the high-accuracy hydraulic power supply of oil pump with buncher or use servo
The hydraulic power system that motor controls.
Described control system 6 can use existing motion controller or nonshared control unit.
Operation principle of the present utility model is as follows:
During work, pressure transducer 2 detect actual pressure (the upper dish applying power to lower wall), then transmit a signal to
Control system 6, control system 6 is according to the pressure signal of sensor feedback, by closed loop control algorithm, determines to top lap 5
Thering is provided and grind accurately or polish pressure, and transmit a signal to precision liquid potential source 7, precision liquid potential source 7 is by controlling for oil supply
The hydraulic flow of cylinder 1, controls the hydraulic power that oil cylinder 1 provides, owing to oil cylinder 1 is by pressure transducer 2 and pressure distribution plate 3
Being connected, pressure distribution plate 3 connects top lap 5 by dowel steel 4, and so, precision liquid potential source 7 provides hydraulic pressure to oil cylinder 1, through pressure
After force transducer 2 distributes with pressure distribution plate 3, dowel steel 4 it is uniformly transferred on top lap 5, drives top lap 5
Lifting.Owing to forming a closed-loop control system between pressure transducer 2, control system 6, precision liquid potential source 7, in this system,
Pressure transducer 2 detects actual pressure, and is carried out the adjustment of hydraulic power by control system 6, by above-mentioned power conducting path,
Thus provide grinding pressure accurately to top lap 5.
When this utility model is applied to Twp-sided polishing machine, polishing disk will be replaced with by top lap 5, also can obtain identical
Effect.
