Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
Embodiment machine safety door as shown in Figure 1 to Figure 3, comprises the machine body 1 being provided with control device, safety door support 2, safety door 3 and the cylinder 4 be located on this machine body 1; Cylinder 4 connection control device and the piston 41 of cylinder connects safety door 3, safety door 3 and safety door support 2 are flexibly connected; Control device orders about safety door 3 along safety door support 2 displacement by cylinder 4, thus realizes safety door 3 and to open or closed.
The present embodiment also comprises the first magnetic valve 5, second magnetic valve 6, first throttle valve 7 and second throttle 8; Normally closed port 61, second magnetic valve 6 that the normal opening 51 of the first magnetic valve connects the second magnetic valve connects the first valve 42 of cylinder by first throttle valve 7; The normally closed port 52 of the first magnetic valve connects the second valve 43 of cylinder by second throttle 8.As to further improvement of this embodiment, also comprise the 3rd choke valve 9 the 4th choke valve 10.The normal opening 51 of the first magnetic valve connects the normally closed port 61 of the second magnetic valve by the 3rd choke valve 9; Second valve 43 of the normally closed port 52 of the first magnetic valve, the 4th choke valve 10, second throttle 8 and cylinder is connected successively.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 safety door support 2, and the piston 41 of cylinder is connected by aluminium block with safety door 3.
The present embodiment also comprises to be opened or closed magnetic sensible switch 101 for responding to safety door 3, and magnetic sensible switch 101 is connected with control device.
Other structure of the present embodiment machine safety door is see prior art.
As further illustrating the present embodiment, its operation principle is now described.In normal boot-strap or program normal process process, the first magnetic valve 5 does not have energising to be in open mode, and the second magnetic valve 6 energising is in normally open, and cylinder piston rises and drives safety door to rise (namely safety door is opened); When the first magnetic valve 5 energising is in normally off (this is when pressing Xiamen decline button or at the end of machine tooling formula), second magnetic valve 6 energising is in opening (the second magnetic valve 6 is only just closed when power-off), and cylinder piston declines and drives safety door to decline (namely safety door is closed).
Now as unexpected power-off, the second magnetic valve 6 closes, the shaping closed region of the first valve 42 to the second magnetic valve 6 of cylinder, and the gas in cylinder 4 cannot be discharged, and safety door 3 is still held open dress state; Now the second magnetic valve 6 is normally closed, and the first magnetic valve 5 often opens no power.In case of "on" position cuts off source of the gas suddenly, the gas in cylinder 4 is under the effect of first throttle valve 7, second throttle 8, the 3rd choke valve 9, the 4th choke valve 10, and door can slowly decline, and this decrease speed can by throttle valve control.The safety of operating personnel is protected these two kinds of situations can prevent in power-off or cut off source of the gas.Now illustrate "on" position incision die source time, the principle why door can slowly decline: cylinder 4 will decline, and the gas in the first valve 42 of cylinder will be discharged outward, and the second valve 43 of cylinder will have source of the gas to enter, and now die and to enter without source of the gas; Gas in first valve 42 of cylinder will be discharged and can only be vented outward with the gravity of cylinder door itself, and first throttle valve 7 can control the size be vented, the speed of namely door decline.
As further illustrating the present embodiment, workflow when the present embodiment delivered to by workpiece by automatic feed mechanism is now described: positioning cylinder 2 implements contractive action, both sides are located acrylic 4 toward localization tool central motion to spacing, now localization tool negative pressure of vacuum absorption workpiece, then positioning cylinder 2 is implemented overhanging action and is pushed open by location acrylic 4, and location action completes.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
