Description

A kind of leakage tester elasticity closure
Technical field
The invention belongs to automobile manufacturing field, more particularly to a kind of elasticity closure of leakage tester.
Background technology
With the reach of science, the living standard more and more higher of people, automobile use in daily life is more and more general And, one of necessity as life.
Current power engineer's workshop machining cylinder body line in, middle leakage tester be to cylinder block passage inner chamber castability whether One of important detecting devices of existing defects, when leakage test is carried out, lathe is carried out by fixture plugging block to workpiece surface Sealing, workpiece surface feature good seal when only blocking just can guarantee that the stability and reliability of leakage test.
The need for cylinder block passage is due to casting technique, so surface boss number is more, when leakage test is carried out, cylinder body Middle leakage tester must carry out closure sealing to cylinder block passage difference boss face simultaneously.Due to each type water channel boss face position and Height is different, and appearance and size is basically identical, to realize that the quick of production built-in unit is remodeled, it is necessary to quick-replaceable leak test Machine the whole series water channel plugging plate.And existing plugging plate uses fixed length design closure, this kind of method must assure that preceding operation processing Part feature surface quality and difference in height stabilization, but existing cylinder body water jacket boss face is due to process layout's limitation or cutter difference, So that there is certain error in processing, necessarily cause the difference in height between two faces not to be fixed value, can so cause wherein one The closure decrement very little in individual face, its sealing can be deteriorated, and erroneous judgement be caused to workpiece, to middle leakage tester leak test FTQ(Disposably Qualification rate)It is very big with stability influence.
For this reason, it is necessary to a kind of new leakage tester elasticity closure is designed, such that it is able to be applied to closure different height Face.
