Abstract
The utility model relates to a water tank for a hydraulic type air tight testing machine; mainly, an upper and a lower water tanks are arranged at the bottom of the testing machine; electromagnetic valves for pressurization and decompression and a guide tube are respectively arranged on both sides of the lower water tank; the top margin of the guide tube is connected with the bottom of an upper water tank, wherein, the electromagnetic valve for pressure is connected with an air compressor. Thereby, the operation of the visual inspection of operators is convenient; the error of a test caused by the lifting of a machine table can be prevented.
Description
The utility model relates to the water tank of the airtight test machine of a kind of hydraulic type, refers to a kind of lifting that utilizes water level especially, with the cisten mechanism of the range estimation operation that reaches airtight test.
Because general engine, finished products such as cylinder, need keep its absolute precision and impermeability, so after manufacturing is finished, need to come test product with the airtight test machine of high precision, and when recording defective products, seek the flaw place by water tank, and known test machine as shown in Figure 1, lie in, the below is respectively equipped with lifting table 11 and water tank 12, when need detect defective products, promptly utilize lifting table 11 that whole smelting tool is descended with test product and be dipped in the water tank 12, seen by the form 121 of water tank 12 for operating personnel and to look bubble generation place, to find out the flaw place of test product, only these modes have operating personnel and lie prostrate to see in ground and look inconvenience and produce the collimation error, and make because of lifting table rocks that smelting tool and test article obturation effect are influenced tests inaccurate disappearance, very undesirable.
The fundamental purpose of the utility model, promptly at the water tank that the airtight test machine of a kind of hydraulic type is provided, the person estimates operation with handled easily, prevents the test error that lifting table may produce.
For reaching above-mentioned purpose, the utility model mainly is provided with a tester table, be provided with the hoistable platform that supplies clamping finished product to be measured in the top of this board, the bottom of board then is provided with, lower header, it is characterized in that: the both sides of this lower header are respectively equipped with pressurization and pressure release solenoid valve and conduit, the apical margin of conduit is connected in the bottom of wooden case, be connected in air compressor and wherein add pressure electromagnetic valve, in order to do by the unlatching that adds pressure electromagnetic valve, air pressure is charged in the lower header, water in this lower header is risen in the upper water box via conduit, make to place the finished product to be measured of smelting tool to be dipped in upper water box, to constitute airtight test.
Wherein: this upper water box surface root edge is provided with a water level controller, in order to do for the water level that detects upper water box, adds closing of pressure electromagnetic valve with control.
After adopting said structure, the utility model is established above lower header in the tester table bottom, and be provided with pressurization and pressure release solenoid valve in these lower header both sides and be connected in the conduit of upper water box, keying by solenoid valve, the water level that makes lower header charges into because of external pressure, and rises to upper water box via conduit, makes the test product that places upper water box be dipped in upper water box, with handled easily person's range estimation operation, and prevent the test error that lifting table may produce.
Below in conjunction with drawings and Examples, the utility model is further described.
The structure and the test implementation illustration intention of board commonly used by Fig. 1 system;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the test implementation illustration intention of the utility model;
Fig. 4 is that originally this is intended to novel test implementation illustration.
See also Fig. 2, the utility model mainly is provided with the hoistable platform 21 of clamping finished product to be measured in the top of tester table 2, the bottom of board 2 then is provided with smelting tool 22 and reaches, lower header 23,24, wherein, the both sides of this lower header 24, be respectively equipped with being referred to as pressurize solenoid valve 241 and pressure release solenoid valve 242, and to being referred to as conduit 243,244, and make this two conduit 243,244 apical margin is connected in the bottom of upper water box 23, this adds pressure electromagnetic valve 241 and then is connected in an air compressor, in order to do by the unlatching that adds pressure electromagnetic valve 241, air pressure is charged in the lower header 24, with the water level of this lower header 24 via conduit 243,244 rise to upper water box 23, and when water level rose to certain altitude, the detection by the water level controller 231 of being located at upper water box surface root edge added pressure electromagnetic valve 241 and close, test product for hoistable platform 21 clampings is dipped in this upper water box 23, in order to do supplying to carry out airtight test.
See also Fig. 3, the utility model is when practical operation, finished product 3 to be measured is placed on the smelting tool 22, when the finished product of being surveyed is defective products, promptly open and add pressure electromagnetic valve 241, air pressure is charged into lower header 24, the water that makes this lower header 24 is because of air pressure, and via conduit 243,244 rise to upper water box 23, and in full during to water level controller 231, close to add pressure electromagnetic valve 241, so, finished product 3 to be measured can be dipped in the water of upper water box 23, for the flaw place of operating personnel, because this upper water box 23 is the middle position that is positioned at test board 2 by observing window 232 detection products to be tested, can be beneficial to personnel's observation, and hoistable platform 21 keeps motionless when rising because of water level, also can prevent effectively that it from rocking, and avoids causing the error of test.
And as shown in Figure 4, when test finished, operating personnel can open pressure release magnet valve 242 by control circuit, with the air pressure in the lower header 24 of releasing, made the water of upper water box 23 flow back to lower header 24 along conduit 243,244, and finished airtight detection.
In sum, the utility model is above, lower header cooperates pressurization or pressure release solenoid valve, makes water level be able to lifting in upper water box, is beneficial to airtight test, except that the range estimation operation that makes operating personnel more the facility, can prevent that still lifting table from rocking the test error that may be produced.
