Referring to Fig. 3, Fig. 3 is the Weighting system pneumatic diagram of an embodiment of the present invention, including Telescopic-cylinder bar P1,
Throttle valve P2, relief valve P3, pressure reducing valve P4, check valve P5, switch P6 and pneumatic triple piece P7.
The basic conception of Weighting system are as follows: connect a check valve P5 and one side by side in the airflow path of balance cylinder 7 and let out
Pressure valve P3, wherein check valve P5 is only capable of allowing air-flow out of external unidirectional inflow balance cylinder 7, the air pressure in balance cylinder 7
When preset value no more than relief valve P3, relief valve P3 is in close state, and at this moment air inlet circuit is into the cavity of balance cylinder 7
Make-up gas, when the intracorporal air pressure of 7 chamber of balance cylinder is greater than the preset value of relief valve P3 setting, relief valve is started to work, to
Outer releasing gas reduces air pressure in balance cylinder 7, when the intracorporal air pressure of 7 chamber of balance cylinder is identical as the preset value of relief valve P3,
Relief valve P3 stops working, and the preset value of relief valve P3 is determined according to the common gravity size of Z axis slide unit 10 and work package 8
Fixed, the preset value of relief valve P3 is identical as the preset value of pressure reducing valve P4 at this time.
As one embodiment, the preset value of pressure reducing valve P4 is regarded the preset value of relief valve P3 by relief valve P3, is subtracted at this time
The preset value of pressure valve P4 is determined according to the common gravity size of Z axis slide unit 10 and work package 8.
When process equipment works normally, (Z axis is sliding with the mover of Z axis linear motor by the Telescopic-cylinder bar P1 of balance cylinder 7
Platform 10) it moves synchronously, it is based on above-mentioned Weighting system, when Z axis slide unit 10 moves downward, 7 cavity of balance cylinder becomes smaller, cylinder interior
Air pressure get higher, when air pressure is more than the preset value of relief valve P3, relief valve P3 start outward lose heart, reduce by 7 chamber of balance cylinder
Intracorporal air pressure, to guarantee that Z axis slide unit 10 works normally；When Z axis slide unit moves upwards, 7 cavity of balance cylinder becomes larger, cylinder
Internal air pressure becomes smaller, at this moment can by air inlet circuit into the cavity of balance cylinder 7 make-up gas, avoid because of balance cylinder 7
The too small influence Z axis slide unit 10 of air pressure works in cavity.
In addition, the present embodiment has also been sequentially connected in series pneumatic triple piece P7 and switch P6 on air inlet circuit along airintake direction,
Realize the air inlet control of balance cylinder 7.The utility model is additionally provided with the throttle valve of the speed for adjusting air inlet and outlet,
In the present embodiment, throttle valve is connected on air inlet circuit and the confluence circuit of pressure release circuit end, in other of the utility model
In embodiment, air inlet circuit and pressure release circuit do not include shared confluence circuit, connect respectively on air inlet circuit and pressure release circuit
There is throttle valve P2.
Specifically, when linear motor works, station 3 slides in Y-axis guide rail 4, and X-axis slide unit 6 is sliding in X-axis guide rail
Dynamic, the Z axis slide unit 10 on X-axis slide unit 6 slides up and down, and is produced by work package 8 to the product being located on station 3
And processing, operating system 9 control the control device in the movement of each linear motor and Weighting system based on machining information
System.
When Z axis slide unit 10 moves downward, the cavity of balance cylinder 7 becomes smaller, and the air pressure of cylinder inside cavity is got higher, and works as air pressure
When preset value more than relief valve P3, relief valve P3 starts to lose heart outward to reduce the intracorporal air pressure of 7 chamber of balance cylinder, to guarantee
Z axis slide unit 10 can work normally；When Z axis slide unit moves upwards, the cavity in balance cylinder 7 becomes larger, the gas of cylinder interior
Buckling is small, at this moment can be avoided by make-up gas in the cavity of air inlet meeting road direction balance cylinder 7 because of gas in 7 cavity of balance cylinder
Small influence Z axis slide unit 10 is pressed through to work.
When Z axis slide unit 10 stops working in a flash, motor will drive 10 stop motion of Z axis slide unit, the chamber of balance cylinder 7
Body size is no longer changed, when the intracorporal air pressure of 7 chamber of balance cylinder is more than the preset value of relief valve P3 setting, relief valve P3
In state discouraged outward, since check valve P5 has single-phase conduction, check valve does not lose heart outward at this time, also not to
Interior make-up gas, when relief valve P3 after a period of work, make the intracorporal air pressure of the chamber of balance cylinder 7 equal to relief valve P3 be arranged
Preset value when, relief valve P3 stops working, and at this moment check valve P5 does not still lose heart outward, not into the cavity of balance cylinder 7
Tonifying Qi, therefore, the intracorporal air pressure of chamber of balance cylinder 7 at this time remain unchanged, due to relief valve P3 setting preset value when root
The total force setting of work package 8 according to Z axis slide unit 10 and on Z axis slide unit 10, so balance cylinder 7 at this time is by stretching
The power that contracting bar P1 gives Z axis slide unit 10 can just offset Z axis slide unit 10 and on Z axis slide unit 10 work package 8 gravity,
So that Z axis slide unit 10 will not slide when idle；The intracorporal air pressure of 7 chamber of balance cylinder is less than relief valve P3 setting
When preset value, relief valve P3 does not work at this time, and air inlet circuit passes through check valve P5 make-up gas into the cavity of balance cylinder 7,
When the intracorporal air pressure of 7 chamber of balance cylinder is identical with the preset value of pressure reducing valve P4, air inlet circuit is automatically stopped tonifying Qi, keeps balance
State.The preset value of relief valve P3 is identical as the preset value of pressure reducing valve P4.
As one embodiment, the preset value of pressure reducing valve P4 is regarded the preset value of relief valve P3 by relief valve P3, is subtracted at this time
The preset value of pressure valve P4 is determined according to the common gravity size of Z axis slide unit 10 and work package 8.
In addition, alarm device 12 sounds an alarm when unexpected situation occurs, staff is reminded to handle in time.
It is illustrating for progress to be implemented to the preferable of the utility model, but the invention is not limited to the reality above
Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention
Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
