Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by it is clear that described embodiment is only a part of embodiment of the present invention, rather than
Whole embodiments.
Embodiment machine safety door as shown in Figure 1 to Figure 3, including the machine body being provided with control device
1st, the safe door bracket 2 on this machine body 1, safety door 3 and cylinder 4；Cylinder 4 connects control
The piston 41 of device and cylinder connects safety door 3, and safety door 3 and safe door bracket 2 are flexibly connected；Control
Device orders about safety door 3 along the displacement of safe door bracket 2 by cylinder 4, thus realize safety door 3 opening
Or closure.
The present embodiment also includes the first magnetic valve 5, the second magnetic valve 6, first throttle valve 7 and second throttle
8；The normally open 51 of the first magnetic valve connects the normally closed port 61 of the second magnetic valve, and the second magnetic valve 6 passes through the
One choke valve 7 connects the first valve 42 of cylinder；The normally closed port 52 of the first magnetic valve passes through second throttle 8
Connect the second valve 43 of cylinder.As to further improvement of this embodiment, also include the 3rd choke valve 9
4th choke valve 10.The normally open 51 of the first magnetic valve connects the normal of the second magnetic valve by the 3rd choke valve 9
Remain silent 61；The second of the normally closed port 52 of the first magnetic valve, the 4th choke valve 10, second throttle 8 and cylinder
Valve 43 is sequentially connected in series.First throttle valve 7, second throttle 8, the 3rd choke valve 9 and the 4th choke valve
10 are one-way throttle valve.
Cylinder 4 is fixed on safe door bracket 2, and the piston 41 of cylinder and safety door 3 are connected by aluminium block.
The present embodiment is also included for sensing the magnetic sensible switch 101 that safety door 3 is opened or closed, magnetic sensible switch
101 and control device connect.
The other structures of the present embodiment machine safety door are referring to prior art.
Further illustrate as to the present embodiment, its operation principle is now described.In normal boot-strap or program just
Often in process, the first magnetic valve 5 does not have energising to be in open mode, and the second magnetic valve 6 energising is often in
Open state, cylinder piston rises and drives safety door to rise (i.e. safety door is opened)；When the first magnetic valve 5 leads to
Electricity is in normally off (this is to press Xiamen to decline during button or at the end of machine tooling formula), the second magnetic valve
6 energisings are in opening (the second magnetic valve 6 only just closes when power is off), and cylinder piston declines and carries
Dynamic safety door declines (i.e. safety door closing).
Now as unexpected power-off, the second magnetic valve 6 closes, first valve the 42 to the second magnetic valve 6 of cylinder
The region of one closing of shaping, the gas in cylinder 4 cannot be discharged, and safety door 3 still keeps it turned on dress state；
Now the second magnetic valve 6 is normally closed, the normally opened no power of the first magnetic valve 5.In case of "on" position sudden shuts off gas
Source, the gas in cylinder 4 is in first throttle valve 7, second throttle 8, the 3rd choke valve the 9, the 4th throttling
In the presence of valve 10, door can slowly decline, and this decrease speed can be by throttle valve control.This two kinds of situations all may be used
To prevent from protecting the safety of operating personnel in the case of power-off or cut-out source of the gas."on" position incision is now described
Die source when, the principle why door can slowly decline：Cylinder 4 will decline, in the first valve 42 of cylinder
Gas will be discharged outward, and the second valve 43 of cylinder will have source of the gas to enter, and no source of the gas of now dying enters；
Gas in first valve 42 of cylinder will be discharged and can only be vented outward with the cylinder door gravity of itself, first segment
Stream valve 7 can control the size of exhaust, that is, the speed that door declines.
Further illustrate as to the present embodiment, now explanation delivers to this reality when workpiece by automatic feed mechanism
Workflow when applying：Positioning cylinder 2 implements contractive action, and both sides positioning acrylic 4 is controlled toward positioning
Tool central motion is implemented outward to spacing, now localization tool negative pressure of vacuum absorption workpiece, then positioning cylinder 2
Stretch action and push open positioning acrylic 4, location action completes.
The invention is not limited in above-mentioned embodiment, if the various changes to the present invention or modification without departing from
The spirit and scope of the present invention, if these change claim and the equivalent technologies belonging to the present invention with modification
Within the scope of, then the present invention is also intended to comprise these changes and modification.
