Description
Technical field
The invention belongs to Engine Block Test field, specifically refer to the interior swollen blocking device of a kind of camshaft hole.
Background technique
The amount of leakage of the water channel of engine cylinder-body, cylinder cap and assembly, oil duct, cavity is directly connected to the overall performance of motor, when testing the leakage rate of water channel, oil duct and cavity, the hole needing shutoff to be correlated with and face, then the whole inner chamber by shutoff is inflated, with leak detector, its leakage rate is detected.When shutoff camshaft hole, if camshaft hole is as a whole or when having installed camshaft cover, traditional shutoff mode is difficult to realize normal shutoff, therefore designs simple to operate, a shutoff reliable camshaft hole endoporus blocking device and just seems particularly important.
The camshaft hole of motor is most to be had oilhole in hole at cylinder cap top, when carrying out shutoff by prior art to it, generally not to install camshaft cover, its shutoff scheme as shown in Figure 1 and Figure 2: have oilhole 5 to need shutoff in camshaft hole 1; Push rod 4 promotes block head 3 under the effect of power source (being generally cylinder, oil cylinder or pneumohydraulic pressure-cylinder, not shown in FIG.), produces distortion under extrusion carry out shutoff oilhole 5 by the polyurethane sealing plug 4 be fixed on block head 3.
The major defect of prior art is:
1, existing camshaft hole endoporus blocking technology, can normally use when block head and push rod under can arranging, but in narrow space, plug and push rod cannot arrange under when cannot use;
2, in single camshaft hole, have multiple hole to need shutoff, and when needing a composition complete cavity, can get up in different holes by this technological scheme in independent shutoff, form relatively independent cavity, therefore cannot use;
3, the shutoff of each camshaft hole needs an independent power source, has oilhole to need shutoff, then need 5 power sources if namely had in 5 camshaft holes;
4, installing camshaft cover, or camshaft hole is an entirety, when namely camshaft hole is a complete cylindrical hole, this scheme cannot use;
5, prior art is difficult to realize manual shutoff.
