Description
Technical field
The utility model relates to auto parts and components air tight test equipment, specifically a kind of cylinder cap air tight test device.
Background technology
Cylinder cap is one of necessary parts in engine, because the water jacket hole of cylinder cap bottom is more, easily cause clamping force uneven and leak gas, affected the accuracy of tightness test, simultaneously, because the structural limitations versatility of existing verifying attachment is poor, cause the cylinder cap of different size need to respectively coordinate an air tight test device, not only improved operation experimentation cost, once produce when corresponding product suspends, to cause verifying attachment idle, and not only cause the waste of the resources of production, and wasted space.The cylinder cap air tight test device that for this reason needs a kind of highly versatile easy to use.
Utility model content
The purpose of this utility model is to provide a kind of cylinder cap air tight test device, has fundamentally solved that existing cylinder cap air tight test device inconvenient operation, applicable cylinder cap specification are single, large, the problem such as testing staff's labour intensity is large takes up room.Its structural design is ingenious, have simple in structure, easy to assembly quick, little, the advantage such as accuracy in detection is high, testing staff's labour intensity is low takes up room.
The purpose of this utility model is achieved in that this cylinder cap air tight test device comprises for the fixing fastener of cylinder cap, be arranged on the compressed air inlet of cylinder cap inlet end, be arranged on variable valve and tensimeter on cylinder cap compressed air outlet, its technical essential is: described fastener comprises fixed mount, be arranged on the water tank of fixed mount bottom, be arranged on the lift cylinder at fixed mount top, be arranged on the vertical guide rail on fixed mount, by the spacing tressel on guide rail of guide wheel, be arranged on the vertical clamping cylinder on tressel, be arranged on the horizontal-clamping cylinder on fixed mount, tressel is arranged on the output terminal of lift cylinder, tressel bottom is provided with backing plate, the output terminal of horizontal-clamping cylinder is provided with clapboard, on backing plate, be also provided with horizontal-clamping portion, between the inclined-plane of horizontal-clamping portion and clapboard, be provided with pinch wheels, the opposite side of horizontal-clamping portion is provided with the limiting section being fixed on tressel, and compressed air inlet is arranged on limiting section, vertically on the inlet end of clamping cylinder, horizontal-clamping cylinder, lift cylinder, is respectively equipped with hand rotary valve.
The advantage the utlity model has and positive technique effect are: lift cylinder drives tressel to complete workpiece to drop to water tank bottom vertical clamping workpiece surface, simultaneously below workpiece water jacket hole directly and tressel base rubber seal by pressure seal, prevent that pressurized air from shifting out from water jacket hole.Therefore, can adopt higher input pressure to test, thereby make assay more accurately and reliably.And while testing for the cylinder cap of different size, only need to change backing plate and seal element.Reduce to greatest extent the quantity of pick-up unit, saved manufacturing cost, reduced labour intensity, saved space.
