Abstract
The utility model belongs to the field of mechanical parts manufacturing, and especially relates to a piston automatic leak test bench which comprises a work bench, a sealed steel ring and a pump station. A gantry crane fixed on the work bench is arranged above the sealed steel ring. The upper part of the gantry crane is hinged with a rotation rod. An end of the rotation rod is respectively hinged with a piston rod of a cylinder and a top end of a pressing rod. The cylinder is arranged on a support plate fixed on the work bench. An end of the pressing rod is fixedly connected with the upper part of the sealed steel ring. The piston automatic leak test bench has the advantages of simple structure and practicability, the piston rod of the cylinder drives the rotation rod and the pressing rod to move, the pressing rod downwardly presses the sealed steel ring tightly under the action of the cylinder piston rod, pressure filling is carried out on the internal part of the shell and then pressure keeping is carried out, whether a reading of a pressure gauge is decreased or not is observed, if the reading is in a permissible range, the shell is a qualified product, otherwise the product is unqualified, the detection is rapid, and the operation is convenient.
Description
Technical field
The utility model belongs to the supporting manufacturing of component of machine field, relates in particular to a kind of piston experiment table that automatically leaks hunting.
Background technology
at present, need to leak hunting at the shell to the piston that completes, whether the shell with the observation piston is qualified, be mainly for the shell mode of leaking hunting of piston in prior art and suppress in body seal is backward, primary structure is for comprising Working gantry, ring gasket and pumping plant, described Working gantry mainly is made 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, described air inlet pipeline is communicated with pumping plant, described ring gasket is positioned at the top of air hole, the top of described ring gasket is provided with the portal frame that is 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.During detection, the shell of piston is placed on and tightens fastening bolt after sealing on ring gasket and hold out against the backward enclosure of shell and suppress, judge by observing barometric reading whether shell leaks gas, the experiment table that leaks hunting of this kind structure needs people workman that fastening bolt is tightened, and work efficiency is lower.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of piston experiment table that automatically leaks hunting is provided, and is simple in structure, improves testing efficiency.
The utility model for achieving the above object, by the following technical solutions: a kind of piston experiment table that automatically leaks hunting, comprise Working gantry, ring gasket and pumping plant, described Working gantry mainly is made 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; Described air inlet pipeline is provided with rain glass, it is characterized in that: the top of described ring gasket is provided with the portal frame that is fixed on worktable, described portal frame upper articulation one bull stick, the end of described bull stick is hinged with the top of the piston rod of cylinder and depression bar respectively, described cylinder is arranged on the back up pad that is fixed on worktable, and the end of described depression bar and ring gasket top are affixed.
Described depression bar is made of the two parts that are threaded.
One side of described worktable is provided with Electric Appliance Cabinet.
Be respectively equipped with individual event valve on described air inlet pipeline and outlet pipe.
Beneficial effect: the utility model is simple in structure, practical, the piston rod of cylinder drives bull stick and depression bar moves, depression bar is downward press seal steel ring under the effect of cylinder piston rod, whether carry out pressurize by after suppressing to enclosure again, observing barometric reading has reduction, if illustrate that in allowed limits this shell is specification product, otherwise, product is substandard product, detects fast simple operation.
