Abstract

The utility model provides air-tightness inspection equipment, which comprises a gas source, a water sink, a water sink bracket for supporting the water sink, and an inflation bench. The inflation bench is arranged inside the water sink. A cylinder bracket is welded above the inflation bench. A cylinder is arranged on the cylinder bracket. The cylinder is connected with a pressure plate through a shaft coupling. A plugging rod is arranged under the pressure plate. The inflation bench is connected with an inflation switch through a pipeline. The lower part of the water sink is provided with a water inlet and the water inlet is connected with a water pipe. A water pump arranged on the water pipe is positioned between the water sink and a water tank. During the inspection of air tightness, a workpiece to be inspected is placed onto the inflation bench and the pressure plate is driven by the cylinder to move downwards. Meanwhile, the plugging rod is simultaneously driven to move downwards, and the port of the workpiece to be inspected is ensured to be docked with the plugging rod. The water pump pumps water to fill the water sink, and then the inflation bench is inflated. Simultaneously, whether bubbles are generated in the water sink or not is observed. The air-tightness inspection equipment has the advantages of simple structure, convenient maintenance, convenient operation, accurate detection for air tightness, and the like.

Description

Air tight test equipment
Technical field
The utility model belongs to the inspection machine technical field, especially relates to a kind of air tight test equipment.
Background technology
Along with rapid development of economy, industries such as standard machinery, automobile, excavation are also prosperous day by day, and these industries all need various power-equipments such as diesel engine, gasoline engine etc., cause the demand of diesel engine, gasoline engine to increase substantially.The housing of diesel engine, gasoline engine is as a kind of indispensable parts, and its production has also got into the large batch of epoch.The housing of engine normally passes through casting; In casting process, produce defectives such as sbrinkage blowhole, crackle sometimes; These defectives cause problems such as oil impregnate, leakage of oil easily, the working environment of severe contamination complete machine, and cause huge waste; Exist hidden danger simultaneously, when serious even cause self-burning of vehicle.Therefore in the housing manufacture process, must carry out impermeability to motor body and detect.But the cost cost of air tight test equipment is higher at present; Unsuitable medium-sized and small enterprises are used, and in medium-sized and small enterprises, generally adopt hand to stop up the mouth of pipe; The operation of other end aeration; And it is placed into tank detects air tightness of workpiece and whether reach requirement, this kind mode hand labor intensity is big, and detection efficiency is low.
Summary of the invention
The problem that the utility model will solve provides a kind of simple in structure, practical, easy to operate, air tight test air tight test equipment accurately, is particularly suitable for checking the impermeability of motor body etc.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of air tight test equipment comprises the tank support of source of the gas, tank, support tank and inflates platform; Said inflation platform is installed in the inside of tank, and the top of inflation platform is welded with the cylinder support, on the cylinder support cylinder is installed; Cylinder is connected with pressing plate through shaft coupling; The below of said pressing plate is equipped with the shutoff bar, and said inflation platform is connected with gas-filled switching tube through pipeline, and the below of tank is provided with water inlet; The water inlet place is connected with water pipe, and the water pipe between tank and the water tank is provided with water pump.
Further, be provided with tensimeter between said gas-filled switching tube and the source of the gas.
Further, said cylinder is stepped on switch through lead and pin and is connected.
Further, the water pipe between said tank and the water pump is provided with water source switch.
Advantage and the good effect that the utlity model has are: when carrying out air tight test work, workpiece to be checked is put on the inflation platform, moves downward with the air cylinder driven pressing plate then; Drive the shutoff bar simultaneously and move downward, and guarantee the shutoff bar and wait to check mouthful joining of workpiece, with water pump with tank pump full water; Open gas-filled switching tube then; Whether in the inflation platform, inflate, observing simultaneously has bubble to produce in the tank, and the utility model makes air tight test more convenient; Have advantages such as simple in structure, easy to maintenance, practical, easy to operate, that air tight test is accurate.

Embodiment
As shown in Figure 1, a kind of air tight test equipment of the utility model comprises source of the gas, tank 1, supports the tank support 13 of tank 1 and inflates platform 6; It is characterized in that: said inflation platform 6 is installed in the inside of tank 1, and the top of inflation platform 6 is welded with cylinder support 3, and cylinder 2 is installed on the cylinder support 3; Cylinder 2 is connected with pressing plate 4 through shaft coupling; The below of said pressing plate 4 is equipped with shutoff bar 5, and said inflation platform 6 is connected with gas-filled switching tube 7 through pipeline, and the below of tank 1 is provided with water inlet; The water inlet place is connected with water pipe, and the water pipe between tank 1 and the water tank 12 is provided with water pump 11.
For the ease of observing the air pressure in the inflation platform 6, between said gas-filled switching tube 7 and source of the gas, tensimeter 8 is set.For the ease of staff's operation, said cylinder 2 is stepped on switch 10 through lead and pin and is connected.Water pipe between said tank 1 and the water pump 11 is provided with water source switch 9.
The course of work of this instance: when carrying out air tight test work, workpiece to be checked is put on the inflation platform 6, opens pin then and step on switch 10; Drive pressing plate 4 with cylinder 2 and move downward, drive shutoff bar 5 simultaneously and move downward, and guarantee shutoff bar 5 and wait to check the mouth of workpiece to join; Open water source switch 9 then; With tank 1 pump full water, open gas-filled switching tube 7 with water pump 11 then, inflation in inflation platform 6; Observe the numerical value whether bubble generation and tensimeter 8 are arranged in the tank 1 simultaneously, adjust air pressure at any time.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
