The pressure water-injection type air tightness testing machine is characterized in that a machine tool gives outs a signal, an electromagnetic valve (8) is opened, and a high-pressure gas in the air inflation water pressing system (3) is inflated in the water storage tank (2); water in the water storage tank flows into the test water channel (5) after being pressed to a water level height set by the detection water level system (7), and an air tightness test is carried out on an automobile hub. According to the utility model, as adoption of pressure water injection, a water leakage phenomenon caused by collision and cracks does not occur, thereby improving the reliability of the machine tool. The water level needs not to be kept in a test barrel, thereby ensuring the service life of the test barrel, the cleanliness of test water and the sight of an operator, and improving the test effect. The air tightness testing machine adopts pressure water injection and does not need a caisson, the volume of the water storage tank is reduced, the material consumption of the machine tool is low, and the cost is low.
Description
Technical field
The utility model belongs to automobile and motorcycle wheel hub air-tight test equipment, is used for the water filling test of horizontal and vertical gas tightness testing machine.
Background technology
Vertical or the horizontal workbench of the general employing of existing automotive hub gas tightness testing machine, by waterflood system water is injected the test bucket, after water covers wheel hub, bubble when leaking gas by aluminium wheel hub in the visual observations water is checked the gas leakage situation of aluminium wheel hub, and this is the air tight test method that domestic most producer selects.The test water flooding regime generally has up and down entry method of testing of pressure injection water filling method of testing and workpiece.Pressure injection water filling method of testing is now most popular, to cooperate by reserve tank and caisson, guaranteeing to come setting-out to enter the test bucket by similar motion in the form of piston in the situation airtight between reserve tank and the caisson and water is taken away, this mode is higher to the welding requirements of water tank, because caisson constantly moves up and down, collision water storage casing has been grown and can cause the fracture by fatigue of tank weld place service time, occurs leaking.
Summary of the invention
For above deficiency, the purpose of this utility model provides a kind of air pressure water injection type gas tightness testing machine, is to make water flood about the original caisson into the air pressure water flood, storing water in water tank, with the mode of inflation/deflation, about the realization water level, thus the test water level of realization wheel hub.
The technical solution adopted in the utility model is: air pressure water injection type gas tightness testing machine, comprise gas-holder, reserve tank, the inflation water pressuring system, the backwater blow-off system, testing flume, stalk and sensed water level system, reserve tank is located at the bottom of testing machine, the upper left side of reserve tank is connected with gas-holder by solenoid valve and tracheae, gas-holder stores gases at high pressure, be provided with stalk in the reserve tank, stalk is connected with testing flume, testing flume is provided with the sensed water level system, it is characterized in that: described lathe sends signal, solenoid valve is opened, and the high pressure gas in the inflation water pressuring system is filled with in the reserve tank; Flow into testing flume to the height of water level of sensed water level default by stalk behind the water pressurized in the reserve tank, water level stops to rise; Automotive hub carries out air-tight test.
Described solenoid valve is opened the backwater blow-off system, and the air in the water tank is emitted, and the water backwater in the testing flume is to water tank, and test is finished.
Described gas-holder is provided with air intake opening and gas outlet, and the bottom is provided with two solenoid valves.
The utility model structure owing to be the air pressure water filling, in the situation that guarantees welding technology, has not had the collision of picture caisson waterflood timing tool stressed, and the phenomenon that can not bump and break and occur leaking has improved the reliability of lathe.Water level need not to remain in the test bucket always, has guaranteed life-span and the cleaning of test water and operator's the sight line of test bucket, improves the test effect.The air pressure water filling need not caisson, has reduced the volume of reserve tank, and the lathe consumptive material is few, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Known by Fig. 1, air pressure water injection type gas tightness testing machine, comprise gas-holder 1, reserve tank 2, inflation water pressuring system 3, backwater blow-off system 4, testing flume 5, stalk 6, sensed water level system 7 forms, reserve tank 2 is located at the bottom of testing machine, the upper left side of reserve tank 2 is connected with gas-holder 1 by solenoid valve 8 and tracheae, gas-holder 1 stores gases at high pressure, gas-holder 1 is provided with air intake opening 9 and gas outlet 10, be provided with stalk 6 in the reserve tank 2, stalk 6 is connected with testing flume 5, the sensed water level system 7 that is provided with of testing flume 5 stores a large amount of gases at high pressure by gas-holder 1, when lathe sends signal to inflation water pressuring system 3; Intrasystem solenoid valve 8 is opened, and the high pressure gas in the gas-holder 1 is filled with in the reserve tank 2; Water is owing to injecting gas in the reserve tank, and water flows into testing flumes 5 by stalk 6 behind the pressurized; When water level rose to the height of water level of sensed water level system 7 settings, water level stopped to rise; Inflation water pressuring system 3 interior solenoid valves 8 cut out, and keep water level; After lathe sent the water-break signal, backwater blow-off system 4 solenoid valves were opened, and the air in the water tank is emitted, owing to draw off air in the reserve tank 2, the water that is in 5 li of testing flumes affects lower water-back to reserve tank 2 what conduct oneself with dignity; When water level falls back on the water level of sensed water level system 7 settings, backwater blow-off system closed electromagnetic valve.Finish a working cycle.
The step of its inflation setting-out work is: the inflation solenoid valve is opened, the high pressure gas that prestores in the gas-holder is filled with reserve tank, and setting-out enters the test bucket, after level switch detects water level and puts in place, the inflation closed electromagnetic valve, lathe begins test job, and after being completed, pressure-releasing electromagnetic valve is opened, water is got back in the reserve tank under the effect of deadweight, the drained level switch of water obtains signal, closes air release, and whole job step finishes.
Owing to be the air pressure water filling, in the situation that guarantees welding technology, there has not been the collision of picture caisson waterflood timing tool stressed, the phenomenon that can not bump and break and occur leaking has improved the reliability of lathe.Moreover water level need not to remain in the test bucket always, guaranteed the life-span of test bucket and the cleaning of test water, guaranteed operator's sight line, improves the test effect.The air pressure water filling need not caisson, has reduced the volume of reserve tank, so the lathe consumptive material reduces cost.The purpose of this utility model is, because lathe only has a water tank, the volume of lathe reduces, every lathe can be the client and saves 1.2 square metres of occupations of land, now the most expensive is exactly the soil, so that enterprise requires the utilization factor in space, workshop is more and more higher, and the space of having adopted the direct economization of this mode, can in limited environment, put more lathe, improve production capacity.
