Description
Affiliated technical field
The utility model relates to wood processing machinery, especially drives the gas-liquid conversion driving device of wood processing machinery working table movement.
Background technique
The power output of hydraulic mechanism is reliable and stable, is highly suitable for action request occasion stably, so wood processing machinery adopts hydraulic mechanism to drive movable workbench in a large number.But hydraulic mechanism also has deficiency, is that hydraulic oil heating value when work is big on the one hand, may produce excessive temperature and damage Sealing as long-time running; Action of hydraulic mechanism is comparatively slow on the other hand, and for reset (idle stroke) of worktable, slow motion has just influenced efficient.
Summary of the invention
In order to overcome the deficiency of existing hydraulic mechanism, the utility model provides a kind of gas-liquid conversion driving device, this device sets the advantage of hydraulic mechanism and pneumatic mechanism, the working stroke of worktable is driven by hydraulic mechanism, reset (idle stroke) of worktable driven by pneumatic mechanism.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of gas-liquid conversion driving device, it is characterized in that: comprise oil storage cylinder, one-way throttle valve, gas-liquid special cylinder, solenoid directional control valve and conduit, the cylinder body of gas-liquid special cylinder is fixedlyed connected with bed piece, its piston rod is connected with stationary table, and its air storing cavity is connected with solenoid directional control valve by conduit; Oil storage cylinder is provided with the piston that its inside is divided into accumulator and gas storage chamber, the accumulator of oil storage cylinder is connected with the liquid storage cylinder of conduit with the gas-liquid special cylinder by one-way throttle valve, the installation direction of one-way throttle valve is, carry out throttling to flowing to oil storage cylinder hydraulic oil from the gas-liquid special cylinder, the gas storage chamber of oil storage cylinder is connected with solenoid directional control valve by conduit.
As to of the present utility model additional and perfect, also be provided with one-way valve between the liquid storage cylinder of gas-liquid special cylinder and the accumulator of oil storage cylinder, the installation direction of one-way valve is the unidirectional conducting of the accumulator of oil storage cylinder to the liquid storage cylinder of gas-liquid special cylinder.
The beneficial effects of the utility model are, the first, and the working stroke of worktable drives in the adjustable mode of hydraulic pressure, and moving of worktable is steadily reliable; The second, worktable reset (idle stroke) drive in the air pressure mode, travelling speed is fast; The 3rd, work control is simple, need not increase oil hydraulic pump or motor; The 4th, the system reliability height is not even long-time running can produce too high temperature rise yet.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Consult Fig. 1, a kind of gas-liquid conversion driving device, comprise oil storage cylinder 1, one-way throttle valve 2, gas-liquid special cylinder 3, solenoid directional control valve 4 and conduit, the cylinder body of gas-liquid special cylinder 3 is fixedlyed connected with bed piece (not drawing among the figure), its piston rod 31 is fixedlyed connected with worktable (not drawing among the figure), and its air storing cavity 32 is connected with solenoid directional control valve 4 by conduit 50; Oil storage cylinder 1 is provided with the piston 10 that its inside is divided into accumulator 11 and gas storage chamber 12, the accumulator 11 of oil storage cylinder 1 is connected with the liquid storage cylinder 33 of gas-liquid special cylinder 3 with conduit 51 by one-way throttle valve 2, the installation direction of one-way throttle valve 2 is, carry out throttling to flow to oil storage cylinder 1 hydraulic oil from gas-liquid special cylinder 3, the gas storage chamber 12 of oil storage cylinder 1 is connected with solenoid directional control valve 4 by conduit 52.
For improving the motion speed of this device, also can between the accumulator 11 of the liquid storage cylinder 33 of gas-liquid special cylinder 3 and oil storage cylinder 1, add one-way valve 6, the installation direction of one-way valve 6 is the unidirectional conducting of the accumulator 11 of oil storage cylinder 1 to the liquid storage cylinder 33 of gas-liquid special cylinder 3.
Working procedure of the present utility model is as follows, pressurized air enters the air storing cavity 32 of gas-liquid special cylinder 3 under the control of solenoid directional control valve 4, promoting its piston rod 31 moves, and then provide power for the working stroke of worktable, on the other hand, hydraulic oil in the liquid storage cylinder 33 is squeezed, and flows back to oil storage cylinder 1 through one-way throttle valve 2.In this process, because the incompressibility of hydraulic oil and the throttling action of one-way throttle valve, so worktable mobile be actually by this device by the hydraulic part controlling and driving, promptly the utility model make the working stroke of worktable utilized hydraulic mechanism move steadily, reliable and adjust characteristic of accurate.After worktable is finished the work stroke, solenoid directional control valve 4 is converted into gas port, pressurized air enters the gas storage chamber 12 of oil storage cylinder 1, make oil storage cylinder 1 interior hydraulic oil be back to the liquid storage cylinder 33 of gas-liquid special cylinder 3 through one-way throttle valve 2 and one-way valve 6, promote the stopper rod 31 of gas-liquid special cylinder 3, it is moving that worktable is made complex displacement.In this process, because the one-way of one-way throttle valve 2 and one-way valve 6, the hydraulic oil of process is not subjected to any throttling action, hydraulic circuit is in complete on state, can regard as the hydraulic oil in gas-liquid special cylinder 3 and the oil storage cylinder 1 as a whole, therefore, the resetting of worktable be actually this device by the pneumatic part controlling and driving, promptly the return stroke of worktable has utilized air pressure mechanism to move characteristics fast.So far, the utility model has been finished a work cycle, and the working stroke of worktable is driven by hydraulic mechanism, and the idle stroke that resets of worktable is driven by pneumatic mechanism.
Above-described specific embodiment only is the utility model preferred embodiment, and the equivalent arrangements of being done according to the utility model claim all should be technology of the present utility model and contains such as.
