Abstract
The invention belongs to the field of mechanical component associated manufacture, and particularly relates to a piston side leakage experiment table. The piston side leakage experiment table comprises a working rack, a sealing steel ring and a pumping station. The working rack is mainly composed of a workbench and four supporting columns which supports the bottom of the workbench. The workbench is provided with a ventilating hole. The ventilating hole is connected with an air inlet pipe and an air outlet pipe. The air inlet pipe is communicated with the pumping station. The sealing steel ring is arranged above the ventilating hole. A portal frame which is fixed on the workbench is arranged above the sealing steel ring. A fastening bolt is arranged on the portal frame at a position which corresponds with the ventilating hole. The air inlet pipe is provided with an air gauge. The piston side leakage experiment table has a simple and practical structure. The sealing steel ring and the fastening bolt closely seal the housing of the piston. Then through pressurizing the inner part of the housing and retaining the pressure, whether read number reduction of the air gauge occurs is observed. If a reduced read number is within an allowed range, the housing is determined as qualified. The piston side leakage experiment table has advantages of quick detection and convenient operation.
Description
Technical field
The invention belongs to the supporting manufacture of component of machine field, relate in particular to a kind of piston experiment table that leaks hunting.
Background technology
At present, need to leak hunting to the shell of the piston completing, whether the shell with observation piston is qualified, in prior art, be mainly in body seal is backward and suppress for the shell mode of leaking hunting of piston, this shell is being put into water, observing in water whether have Bubble formation, the complicated structure of this kind of leak-checking apparatus, need multiple positioning tools just can complete the work of leaking hunting, testing efficiency is lower.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, and a kind of piston experiment table that leaks hunting is provided, simple in structure, improve testing efficiency.
The present invention for achieving the above object, by the following technical solutions: a kind of piston experiment table that leaks hunting, it is characterized in that: comprise Working gantry, ring gasket and pumping plant, described Working gantry is mainly made up of worktable and four support columns being supported on worktable bottom, described worktable is provided with air hole, this air hole is connected with respectively air inlet pipeline and outlet pipe, and described air inlet pipeline is communicated with pumping plant, and described ring gasket is positioned at the top of air hole; The top of described ring gasket is provided with the portal frame being fixed on worktable, and the position corresponding to air hole on described portal frame is provided with fastening bolt; Described air inlet pipeline is provided with rain glass.
Also comprise the pressing plate of a shell for clamping piston.
Described fastening bolt matches with the thread bush on portal frame.
The both sides of described thread bush are provided with reinforcement.
On described air inlet pipeline and outlet pipe, be respectively equipped with individual event valve.
Beneficial effect: the present invention is simple in structure, practical, ring gasket and fastening bolt seal the shell of piston closely, carry out pressurize by after suppressing to enclosure again, observe barometric reading and whether have reduction, if illustrate that in allowed limits this shell is specification product, otherwise product is substandard product, detect fast simple operation.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: 1, worktable; 2, ring gasket; 3, support column; 4, air hole; 5, air inlet pipeline; 6, outlet pipe; 7, portal frame; 8, fastening bolt; 9, rain glass; 10, thread bush; 11, reinforcement.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of piston experiment table that leaks hunting, comprise Working gantry, ring gasket 2 and pumping plant (not shown), described Working gantry is mainly made up of worktable 1 and four support columns 3 being supported on worktable bottom, described worktable is provided with air hole 4, and this air hole is connected with respectively air inlet pipeline 5 and outlet pipe 6, and described air inlet pipeline is communicated with pumping plant, described ring gasket is positioned at the top of air hole, and sealing steel ring is used for the body seal of piston; The top of described ring gasket is provided with the portal frame 7 being fixed on worktable, on described portal frame, is provided with fastening bolt 8 corresponding to the position of air hole; Described air inlet pipeline is provided with rain glass 9, determines that by observing barometric reading whether product is qualified.In order to increase the lifting surface area of fastening bolt on shell, also comprise the pressing plate of a shell for clamping piston.In the present invention, described fastening bolt matches with the thread bush 10 on portal frame.More firm for what thread bush and portal frame were fixed, the both sides of described thread bush are provided with reinforcement 11.On described air inlet pipeline and outlet pipe, be respectively equipped with individual event valve, prevent the reverse refluence of gas.
The present invention is simple in structure, practical, ring gasket and fastening bolt seal the shell of piston closely, carry out pressurize by after suppressing to enclosure again, observe barometric reading and whether have reduction, if illustrate that in allowed limits this shell is specification product, otherwise product is substandard product, detect fast simple operation.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
