Abstract
A water injection mode of a hub air tightness testing machine comprises an air storage tank (1), a water storage tank (2), an air inflation water pressing system (3), a water returning air deflating system (4), a testing water groove (5), a liquid lifting pipe (6), and a water level detecting system (7). The water injection mode is characterized in that a large amount of high pressure gas is stored in the air storage tank (1), when a machine tool sends a signal to the air inflation water pressing system (3), a solenoid valve in the system is opened, and the high pressure gas in the air storage tank (1) is filled to the water storage tank (2); when a water level is lowered down to the preset water level of the water level detecting system, the solenoid valve of the water returning air deflating system is closed, and then a working cycle is finished. According to the water injection mode of the hub air tightness testing machine, water is injected through the air pressure, a caisson is not needed, the size of the water storage tank is reduced, materials consumed by the machine tool are reduced, and cost is reduced. More machine tools can be placed in a limited environment, and productivity is improved.
Description
Technical field
The invention belongs to automobile and motorcycle wheel hub air-tight test equipment, can be widely used in 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 for use.The test water flooding regime generally has pressure injection water filling method of testing and workpiece entry method of testing up and down.Pressure injection water filling method of testing is most popular now.He cooperates by reserve tank and caisson, guaranteeing under the situation airtight between reserve tank and the caisson to come setting-out to go into the test bucket and water is taken away by similar motion in the form of piston, this mode is higher to the welding requirements of water tank, because caisson constantly moves up and down, collision water storage casing, grown service time and can cause the fracture by fatigue of tank weld place, occurred leaking.Workpiece entry method of testing lathe up and down so eliminate gradually, is not done explanation owing to find that in use very big potential safety hazard is arranged here.
Summary of the invention
The deficiency on the setting-out mode at above-mentioned wheel hub gas tightness testing machine the objective of the invention is to adopt the water tank water storage, with the mode that charges and discharge gas, and about the realization water level, thus the test water level of realization wheel hub.
Technical scheme of the present invention realizes in the following manner: the water flooding regime of wheel hub gas tightness testing machine, have with lower member and constitute: gas-holder, reserve tank, inflation water pressuring system, backwater blow-off system, testing flume, stalk and sensed water level system form, it is characterized in that: described by a large amount of gases at high pressure of gas-holder storage, when lathe sends signal to the inflation water pressuring system; Intrasystem solenoid valve is opened, and the high pressure gas in the gas-holder is charged in the reserve tank; Water is owing to injecting gas in the reserve tank, and water flows into testing flume by stalk behind the pressurized; When water level rose to the height of water level of sensed water level default, water level stopped to rise; Closed electromagnetic valve in the inflation water pressuring system keeps water level; After lathe sent the water-break signal, backwater blow-off system solenoid valve was opened, and the air in the water tank is emitted, owing to draw off air in the reserve tank, the water that is in the testing flume influences lower water-back to water tank what conduct oneself with dignity; When water level falls back on the water level of water level detecting default, backwater blow-off system closed electromagnetic valve.Finish a working cycle.
The present invention owing to be the air pressure water filling, under the situation that guarantees welding technology, has not had the collision of picture caisson waterflood timing tool stressed, and the phenomenon that can bump and break and occur leaking has not 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 reduces.Because lathe has only 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 enterprise requires more and more higher to the workshop utilization of space, more lathe can be put in the space of having adopted the direct economization of this mode in limited environment, improve production capacity.

Embodiment
Known by Fig. 1, the water flooding regime of wheel hub gas tightness testing machine, have with lower member and constitute: gas-holder 1, reserve tank 2, inflation water pressuring system 3, backwater blow-off system 4, testing flume 5, stalk 6 and sensed water level system 7 form, store 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 is opened, and the high pressure gas in the gas-holder 1 is charged in the reserve tank 2; Water is owing to injecting gas in the reserve tank 2, 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; Closed electromagnetic valve in the inflation water pressuring system 3 keeps 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 2 is emitted, owing to draw off air in the reserve tank, the water that is in the testing flume influences lower water-back to water tank what conduct oneself with dignity; When water level falls back on the water level of water level detecting default, backwater blow-off system closed electromagnetic valve.Finish a working cycle.
