Working principle:

The concrete operation step of the utility model are as follows:

1. preparation: part to be measured being placed on the locker of work platform sinistral first, water is filled in water tank；

2. removing pressing plate: starting pressing plate cylinder carries out telescopic rod retract action, so that top board separates (such as Fig. 4 with bottom plate It is shown), then the lower platen being located between the two is under no restraint, and two lower platen taking-ups are placed on work platform sinistral and are waited for Survey one side of part；

3. part to be measured loads: part to be measured being placed sequentially in the survey part slot on lower platen, the survey part slot of two lower platens After piling, lower platen is put back between top board and bottom plate, starting pressing plate cylinder carries out telescopic rod extending action, so that upper pressure Plate merges with bottom plate, and lower platen is compressed (as shown in Figure 3)；

4. part leaks hunting: starting two cylinders that leak hunting and carry out telescopic rod retract action, the then survey being fixedly connected with telescopic rod Intermediate plate, connecting rod of leaking hunting, supporting plate simultaneously operation are leaked, and then the press plate mechanism being located on supporting plate is driven to sink down into water tank (at least guarantee complete submerged of top board；As shown in Figure 6), the gas in caisson is passed through by the pressing plate stomata of bottom plate Floor cavities, and then the inner cavity of part to be measured is made to have gas；

5. observing and recording: whether staff has bubble dew on the milling plane that device external observes each part to be measured Out, and remember the position of the part；

6. label distinguish: starting two leak hunting cylinders carry out telescopic rod extending action (as shown in Fig. 7), press plate mechanism by Moved in water with the position of marking mechanism level (be exactly, thimble and surveyed part and be in same level position), start Two mark cylinders carry out telescopic rod and extend and retract movement (Fig. 9 to Figure 10 returns state shown in Fig. 9), so that thimble is hit It hits and has surveyed part, generate pitting label in piece surface, finished for indicating that these parts have detected；

Place superiority and inferiority part 7. distinguishing: starting pressing plate cylinder carries out telescopic rod retract action, and top board is separated with bottom plate, taken Lower platen (as shown in Figure 4) out, by the rejected part of gas leakage bubble is removed and is placed on work platform dextral in water before (it is mainly used for distinguishing rejected part, can actually be placed in any different utensil) in pallet, then by qualified part It is placed in another pallet.

Above step is repeated, the work of leaking hunting to a large amount of parts to be measured can be completed, not need this practical new when work finishes When type, mark cylinders retract, the cylinder that leaks hunting stretches out, and pressing plate cylinder stretches out, and opens the switch valve of water tank bottom, empties in water tank Water closes caisson, completes the use of the utility model.

Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art Personnel embody the principles of the present invention to some variations that some of them part may be made, and belong to the utility model Protection scope within.
