The pallet location switch 16 matched with buffer portion 7 is also provided with in described base plate 1.
The material blocking rod location switch 17 matched with the bottom of material blocking rod 4 is also provided with in described cylinder body 3.
Compared with the existing technology, tool has the following advantages in the present invention:
The pneumatic gear of this kind of version stops device, its structure is simple, design ingenious, rationally distributed, it stops existing for device for traditional standardized gear: be difficult to select according to actual needs gear to stop stroke, the defect such as with high costs, design a kind of special construction utilizing source of the gas, it can select arbitrarily gear to stop stroke as required on the one hand, be that a kind of gear of nonstandardized technique stops structure, therefore its specific aim is comparatively strong, is applicable to the occasion that some has specific demand; Also to stop device than traditional gear lower for its cost in addition, and then reduce the operating cost of enterprise; It is also designed with pressurize and arrives level detecting apparatus simultaneously, and its particularity run and reliability can both be protected.Therefore can say that it has possessed multiple advantage, special for being suitable for applying in the art, its market outlook are very wide.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As shown in Figures 1 to 4: a kind of pneumatic gear stops device, comprise the base plate 1 based on, length direction on even keel along base plate 1 is provided with the axis of guide 2, this axis of guide 2 slidably connects the cylinder body 3 longitudinally arranged, the material blocking rod 4 that can vertically move is provided with in cylinder body 3, material blocking rod 4 is socketed in backgauge rod aperture 15, and this material blocking rod 4 is controlled by the electromagnetic valve be arranged in cylinder body 3, is also provided with spring 5 in the below of material blocking rod 4 simultaneously, the shock strut 6 matched with cylinder body 3 is also horizontally disposed with in base plate 1, this shock strut 6 is slidably socketed in buffer portion 7, the piston 8 being positioned at shock strut 6 end is then among the cushion chamber of buffer portion 7, cushion chamber is separated into large chamber 10 and loculus 11 two parts by this piston 8, and large chamber 10 is wherein close cylinder body 3 direction that, cylinder body 1 is also provided with the triggering roller 12 that can move relative to base plate 1 along with cylinder body 3, base plate 1 then swings the skewback 13 be connected with triggering roller 12 and matching, this skewback 13 is connected with the valve on the pressurize pipeline be communicated with on loculus 11, the bleeder line in large chamber 10 is then provided with speed governing check valve, and be connected by pipeline between the admission line in large chamber 10 and the deflation hole 14 be opened on cylinder body 3, and deflation hole 14 described here is positioned at the upper edge place of backgauge rod aperture 15, the pallet location switch 16 matched with buffer portion 7 is provided with in base plate 1, the material blocking rod location switch 17 matched with the bottom of material blocking rod 4 is provided with in cylinder body 3.
The working process that the pneumatic gear of the embodiment of the present invention stops device is as follows: be arranged on by this device and process on position that (assembling) station matches, when needing this device to work, electromagnetic valve does not give electricity, material blocking rod 4 is in the state of ejecting under the effect of spring 5, pallet marches to this device place under the effect of roller-way, after the collision block of pallet bottom collides the top of material blocking rod 4, cylinder body 3 laterally slides along the axis of guide 2, in the process of cylinder body 3 movement, gas in large chamber 10 is discharged, and the moving velocity of cylinder body 3 can change by regulating the speed governing check valve on the bleeder line of large chamber 10, after gas in large chamber 10 is all discharged, the end movement of buffer portion 7 is to end position, namely pallet location switch 16 place is moved to, pallet location switch 16 sends signal, notice control system pallet has moved to gear off-position and has put, in the process that cylinder body 3 moves, the triggering roller 12 be connected on cylinder body 3 also can move relative to base plate 1, and skewback 13 is pressed, the valve be connected with skewback 13 then can be opened, by injecting the gas with certain pressure in pressure maintaining pipe road direction loculus 11, this part gas can ensure that piston 8 can not counter motion, to keep the invariant position of pallet,
Workpiece now on pallet can implement the operations such as processing, assembling, after operation terminates, when needing to let pass, electromagnetic valve gives electricity, and material blocking rod 4 reclaims, after the top of material blocking rod 4 departs from the contact with pallet collision block, pallet continues to advance under the effect of roller-way, and when after the end position that material blocking rod 4 moves on the lower, material blocking rod location switch 17 detects that material blocking rod 4 motion puts in place, send signal to control system, inform that control system material blocking rod 4 has been in and reclaim state completely; When the top of material blocking rod 4 is retracted to after in backgauge rod aperture 15, the deflation hole 14 being positioned at backgauge rod aperture 15 top is opened, gas enters large chamber 10 by pipeline, loculus 11 starts exhaust simultaneously, the volume in large chamber 10 becomes large gradually, at the effect lower cylinder body 3 of large chamber 10 internal gas pressure along the axis of guide 2 counter motion to initial position; After above-mentioned motion completes, electromagnetic valve power-off, under the effect of spring 5, material blocking rod 4 pushes up back original position, waits for backgauge operation next time.
