After employing above-mentioned technical proposal, the beneficial effects of the utility model are：
Because air compressor machine assembly device for detecting sealability includes bottom plate, base and column are fixed with bottom plate, base is
The drum-shaped structure of upper end open, the side of base are provided with the air inlet of connect base inner chamber, and column upper end is fixedly connected with
Crossbeam, crossbeam are provided with tapped through hole, and tapped through hole internal thread is connected with leading screw, and the upper end of leading screw is provided with handle, under leading screw
End is fixed with protective plate, and protective plate is corresponding up and down with base；When detecting the air-tightness of air compressor machine, by the flange face branch of crankcase
Support on the upper surface of base, protective plate is resisted against on rear end cap by rotating threaded shaft, the position of fixed air compressor machine, flange face and bottom
Seat is tightly connected, and by air inlet toward gases at high pressure are passed through in base, gases at high pressure are by between the input shaft and crankcase of bent axle
Space enter in the cavity that surrounds jointly of cylinder body, piston, crankcase and rear end cap, observe the combination of rear end cap and crankcase
Whether the faying face in face, cylinder body and crankcase has bubble generation, such as bubble-free generation, then illustrates that air compressor machine meets requirement of dispatching from the factory.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, and it is not used in restriction the utility model.
As Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are jointly shown, a kind of air compressor machine assembly device for detecting sealability, including：Horizontal bottom
Plate 1, base 8 and column 2 are respectively fixedly connected with by bolt on bottom plate 1, base 8 is located at the side of column 2.
Base 8 is the drum-shaped structure of upper end open, and the side of base 8 is provided with the air inlet being connected with the inner chamber of base 8
Mouth 81, the upper surface of base 8 is provided with sealing ring.
The upper end of column 2 is bolted to connection horizontal crossbeam 3, and the end of crossbeam 3 is provided with tapped through hole 31, spiral shell
