Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Figure 1-3, a kind of pressure control device, comprise Z axle travel mechanism 1, pressure heads mechanism 2, spring 3, cylinder 4, with barometric pneumatic control valve and the clock gauge 5 that is used for the measuring spring elongation, described spring 3 is connected between Z axle travel mechanism 1 and the pressure heads mechanism 2, described cylinder 4 is fixed in the Z axle travel mechanism 1, the push rod of this cylinder 4 is connected with pressure heads mechanism 2, described pneumatic control valve is located on the cylinder 4, described clock gauge 5 is fixed in the Z axle travel mechanism 1, and its measuring junction fully contacts with pressure heads mechanism 2.
Described clock gauge 5 adopts striker formula clock gauge, and its needle pellet fully contacts with pressure heads mechanism 2; Described Z axle travel mechanism 1 comprises that frame 6, line slideway 7, straight line move module 8 and drive straight line and moves the common servomotor 9 that module moves up and down, described frame 6 and line slideway 7 all are fixed in straight line and move on the module 8, and described straight line moves module 8 and is in transmission connection with common servomotor 9; Described pressure heads mechanism 2 comprises pressure head frame 10 and pressure head 11, and described pressure head frame 10 is slidingly connected with line slideway 7, and described pressure head 11 is fixed in the pressure head frame 10 times; Described spring 3 is connected between frame 6 and the pressure head frame 10; Described cylinder 4 is fixed on the frame 6; The utility model is to utilize clock gauge to measure the elongation x of spring under cylinder power output N effect that connects pressure heads mechanism and Z axle travel mechanism.When boarded head pressing object 12, pressure heads mechanism is moved up with respect to Z axle travel mechanism makes spring come back to initial length apart from x, think that then this moment, boarded head acted on the pressure size of object and the equal and opposite in direction of cylinder power output N, at this moment read the magnitude numerical value that rain glass numerical value just can obtain the cylinder power output, regulate atmospheric pressure value by pneumatic control valve, just can realize accurate control boarded head pressure.
Embodiment
The mechanism of present embodiment mainly forms pressure heads mechanism by working head frame and working head; Move module, line slideway and common servomotor by frame, straight line and form Z axle travel mechanism; Line slideway is fixed in and not only plays the effect of connection between Z axle travel mechanism and the pressure heads mechanism pressure heads mechanism is slided up and down with respect to Z axle travel mechanism; Cylinder is fixed in the Z axle travel mechanism and the push rod of power output is connected with pressure heads mechanism, and cylinder power output size is regulated by the barometric pneumatic control valve of being with of contact with it; Spring connects pressure head and the dynamic balance effect plays in Z axle travel mechanism; Striker formula clock gauge is fixed in the Z axle travel mechanism and needle pellet will fully be touched with pressure heads mechanism one plane.
Promptly debug after mechanism's assembling:
1, elder generation sets to zero air pressure and makes not power output of cylinder.Pressure heads mechanism just just can be with respect to Z axle travel mechanism to lower slider under the pulling force effect of spring, and this moment, spring tension F equaled the gravity G (F=G) of pressure heads mechanism.The relative position of Z axle travel mechanism and pressure heads mechanism just can not change when equilibrium state, and therefore the numerical value of handle striker formula this moment clock gauge is designated as 0 point.
2, adjust band rain glass pneumatic control valve, make cylinder power output N.Pressure heads mechanism moves down with respect to Z axle travel mechanism under the promotion of cylinder, the spring elongation, and spring tension F1 equals pressure head gravity G and adds upper cylinder power output N (F1=G+N).This moment, the numerical value of clock gauge was changed into x (F1-F=k*x k is a elastic coefficient), and this x value just is the elongation of spring.
3, with pressure transducer as on the workplace, operating personnel start the motion of driven by servomotor boarded head, up to the pressure head lower surface is contacted with pressure transducer, and the numerical value that continues to move down pressure transducer constantly rises (because pressure transducer is incompressible, so this moment, pressure heads mechanism just moved upward with respect to Z axle travel mechanism) turn back to 0 boarded head up to clock gauge numerical value from x and stop to move down, this moment spring tension and pressure head gravitational equilibrium F-G=0, so the size of the power N that just exports for pneumatic cylinder of the numerical value that shows of pressure transducer at this moment.
4, constantly adjusting each force value that pneumatic control valve is shown to pressure transducer to need and write down barometric numerical value, is that 0.15Mpa........... gets off resulting data recording for use in the future when air pressure is 0.1Mpa, 6N when being 5N such as pressure.
After the boarded head debugging is finished, as long as adjust atmospheric pressure value according to the data of record, stop when clock gauge is got back to 0 position whenever boarded head moves downward, the pressure of the pressing of boarded head just is the pairing force value of this atmospheric pressure value on the tables of data at this moment.So just, realized control to boarded head pressure.
