Before the start, with circulating work platform is different up and down local time, need not to install additional a slide unit, the secondary guide rail at two ends rests on respectively on the diagonal angle of two row workbench, become mated condition with table slide, on the secondary guide rail working slider is housed respectively, the position that other slide unit sets in advance is the same with the position that circulating work platform up and down sets in advance.

During start, the energising air feed, slide unit anchor clamps on the secondary guide rail of original position install part to be processed, press starting switch, this is equivalent to two groups does not have the automatic intermittent circulating work platform of the up and down loop structure of return mechanism to move simultaneously, at the beginning, auxiliary propelling movement cylinder 40 air inlets of initial sum diagonal position, the slide unit that is promoting on the secondary guide rail of initial sum diagonal position advances to separately First guide rail and slide unit composite set, after the slide unit on the secondary guide rail in two ends enters the first job position, be subjected to the two ends cross slide way of outside electrical equipment control and Rodless cylinder 47 air inlets on the slide rest device, because the slide block of Rodless cylinder 47 is fixed on the horizontal slide unit, the slide block secondary guide rail that drives on the horizontal slide unit that advances docks with the table slide of another row, ensuing operation is consistent with the automatic intermittent circulating work platform of loop structure up and down, until last pneumatic thrust unit of two groups circulating work platform is shifted slide unit onto on the secondary track-type facilities of horizontal slide unit, behind the return, be subjected to two ends cross slide way and the 47 reverse air inlets of the Rodless cylinder on the slide rest device of outside electrical equipment control, the secondary guide rail that drives on the horizontal slide unit is got back to initial position, and a work period finishes.

3, the device when the automatic intermittent circulating work platform is single workbench independent loops work

The automatic intermittent circulating work platform is for circulation up and down or can switch to the work of single workbench independent loops during plane circulation.

The below is with one group of workbench wherein, a workbench has 3 working positions, the automatic drilling that is used as in the machining is example explanation automatic intermittent circulating work platform principle: before (such as Figure 21) start, install anchor clamps on the slide unit, the automatic drilling unit head is installed and is adjusted to the right place.

In one group two workbench, one is the slide unit that connecting of pneumatic pull unit with being connected is the slide unit that pneumatic thrust unit is connecting, back and forth circulation on workbench separately, starting switch is installed separately, the workbench that is equivalent to two separate units is worked alone respectively, different parts can be installed respectively process.

Two consistent first spacing centering blocks 23 on stopping means are located at open position, and a rear moving spacing centering block 50 is located at blocking position, and a rear spacing centering block 23 is located at again open position again.

The cylinder 12 of controlling pneumatic pull unit sets in advance with slide unit and is stretching out extreme position, and the cylinder 12 of controlling pneumatic thrust unit sets in advance at punctured position with slide unit.

The slide unit list workbench independent loops operation principle that pneumatic pull unit is connecting:

During start, the energising air feed, install part to be processed at slide unit, press starting switch, cylinder 12 cylinder rods of the outside electrical equipment control that links shrink, and advance with slide unit, simultaneously, limiting cylinder 21 air inlets that slide unit moves on the stopping means are stretched out, drive gag lever post 20 and rotate, be fixed on the spacing centering block of on the gag lever post 20 first 23 from open position, turn to blocking position, when the position block 11 of slide unit is run into stop screw 24 on the spacing centering block 23, be stressed, working slider moves stopping means integral body and retreats, and buffer spring 28 by compression, until cylinder support plate 22 is run into buffer casting 27, slide unit puts in place and stops.It is the same that operation control is advanced with slide unit with above-mentioned pneumatic pull unit, until the 3rd automatic drilling unit head process finishing of last station namely, touch the travel switch that stops on the automatic drilling unit head, at this moment, spacing centering block 23 is motionless, is subjected to the cylinder 12 reverse air inlets of outside electrical equipment control, directly with the slide unit return, simultaneously, limiting cylinder 21 pressure releases at two ends and logical atmosphere.

Moving spacing centering block 50 that is located at open position in the middle of the slide unit return is crossed, advance to first the spacing centering block 23 that is in blocking position, the fixing slide carriage 7 of slide unit or adjusting slide 8 and position block 11, hit the inclined-plane (such as Figure 17) of pressing to this spacing centering block 23, the inclined-plane corresponding with inclined-plane on this spacing centering block 23 also arranged on the position block 11, owing to also lead at this moment atmosphere after limiting cylinder 21 pressure releases at two ends, the limiting cylinder 21 extraneous cylinder rod of ining succession, be stressed or pulling force can free-extension, and again with spacing centering block 23 interlocks, the inclined-plane hits the downward horizontal component of pressing spacing centering block 23 to form, make spacing centering block 23 turn to open position from blocking position, slide unit moves on, and stretches out extreme position until the cylinder rod of cylinder 12 rests on, and namely slide unit is got back to the position that sets in advance when initial.A work period finishes, and behind the renewal part, presses starting switch, and second work period begins.

The slide unit list workbench independent loops operation principle that slide unit list workbench independent loops operation principle and the pneumatic pull unit that pneumatic thrust unit is connecting connecting is consistent, difference is because that cylinder 12 is installed is towards the opposite, during operation, promote the slide unit operation of advancing by stretching out cylinder rod, then shrink cylinder rod during return.
