Abstract

The utility model relates to a plunger cylinder pressure-tight test device which comprises a test bench and a pressure supply system. At least one pair of plunger cylinder clamping stations is arranged on the test bench in a left-and-right symmetry mode. The pressure supply system comprises an oil tank, an oil hydraulic pump and a reversing valve, wherein an inlet of the oil hydraulic pump is connected with the oil tank, an outlet of the oil hydraulic pump is connected with an oil inlet of the reversing valve, a left outlet and a right outlet of the reversing valve are respectively provided with a connecting oil tube which is communicated into a left clamping station and a right clamping station, the clamping stations are grooves, and a communicating groove is arranged between the left clamping station and the right clamping station. The reversing valve is a two-position four-way reversing valve. The number of the clamping stations is 2-5 pairs. The plunger cylinder pressure-tight test device has the advantages of being capable of lightening the physical force of workers, simple and convenient to operate, strong in safety and high in production efficiency due to the facts that two plunger cylinders are pressed toward each other in an opposite mode, and resetting of plungers is completed.

Description

A kind of plunger cylinder Withstand test device
Technical field
The utility model relates to the plunger cylinder technical field, relates in particular to a kind of plunger cylinder Withstand test device.
Background technique
Plunger cylinder is industrial important hydraulic parts commonly used, is characterized in only having a filler opening, and when squeezing into pressure oil in from filler opening to cylinder barrel, plunger outwards advances under the oil pressure effect; Plunger returns, and need rely on external force.When plunger cylinder is carried out voltage-withstand test, after squeezing into oil pressure, also need by applying external force with plunger return at present.For small-sized oil cylinder, need by manually pushing; For mill type cylinder, also need its vertical placement, the bottom fixes, and adds loads in the above and just can be pressed into plunger.This test way, labor intensity is large, poor stability, and especially to a large amount of plunger cylinders to be tested, efficient is very low.
The model utility content
The utility model provides a kind of plunger cylinder Withstand test device for above-mentioned the deficiencies in the prior art.To reduce test labor intensity, improve testing efficiency.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of plunger cylinder Withstand test device, comprise test stand and supply pressing system, left and right at least one pair of plunger cylinder station that is installed that is arranged with on described test stand, the described pressing system that supplies comprises fuel tank, oil hydraulic pump and selector valve, described oil hydraulic pump entrance is connected with described fuel tank, described oil hydraulic pump outlet is connected with described selector valve filler opening, and the left and right outlet of described selector valve is respectively equipped with the connected pipes that leads to the described left and right station that is installed.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the described station that is installed is groove, and described left and right being installed is provided with connectivity slot between station.
Further, described selector valve is two-position four way change valve.
Further, the described station that is installed is provided with 2-5 pair.
The beneficial effects of the utility model are: by two plunger cylinders mutually to pressing, complete plunger return, it is high that this plunger cylinder Withstand test device can alleviate workman's muscle power, easy and simple to handle, high safety, manufacturing efficiency.

Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figures 1 to 4, a kind of plunger cylinder Withstand test device, comprise test stand 11 and supply pressing system, left and right at least one pair of plunger cylinder station 1 that is installed that is arranged with on described test stand 11, the described pressing system that supplies comprises fuel tank 2, oil hydraulic pump 3 and selector valve 4, described oil hydraulic pump 3 entrances are connected with described fuel tank 2, and described oil hydraulic pump 3 outlets are connected with described selector valve 4 filler openings, and the left and right outlet of described selector valve 4 is respectively equipped with the connected pipes 5 that leads to the described left and right station 1 that is installed.
The described station 1 that is installed is groove 9, and described left and right being installed is provided with connectivity slot 10 between station.
Described selector valve 4 is two-position four way change valves.
The described station 1 that is installed is provided with 2-5 pair.
Working principle of the present utility model: first plunger cylinder 8 to be measured being packed into respectively in pairs during test is installed in station 1, is connected by connecting sleeve 6 among the Cylinder Plunger 7 of positioned opposite.Left and right plunger cylinder 8 is communicated with left and right connected pipes 5 respectively.Start for pressing system, when the plunger cylinder punching press of left side, left Cylinder Plunger is pressed into cylinder bottom with the right side Cylinder Plunger resets it.If in like manner give the right side pressurising, the left side is resetted.Therefore can repeatedly fill, pressure release work, both can test withstand voltagely, can also carry out life test.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
