Description
Technical field
The utility model belongs to detection technique field, relates to a kind of air-tightness detection device, particularly the bubble-tight equipment of a kind of inspection vehicle plastic oil pan.
Background technology
Oil sump (English name is: OilPan) is positioned at engine bottom: dismantled and assembled, and by the shell of crankcase seals as oil storage tank.Oil sump is the Lower Half of crankcase, is also called lower crankcase.It can prevent impurity from entering, and collects and store the lubricating oil flowed back to by each friction surface of diesel engine, and non-dramatic song partial heat, prevents oil ageing.So in automobile engine oil pan assembly production run, need to detect its impermeability, existing detection adopts manually to carry out, the automobile engine oil pan being about to close is immersed in the water, in water, engine sump tank is filled and add pressurized air, observe engine sump tank and whether there is leakage.This operation labour intensity is large, inefficiency, and adopts artificial press seal part, and dynamics is not easy to control, and its Detection job is unstable.
Owing to there is this problem, through retrieval, find that there is Chinese patent literature and disclose a kind of test machine for detecting gas tightness of engine oil pan [Authorization Notice No.: CN101446511B].Although this machine instead of manually, but still water need be utilized detect, and this device is talked about not high automatically, also need staff to make more cooperating.
Utility model content
The purpose of this utility model there are the problems referred to above for existing technology, and propose a kind of auto plastics oil sump testing apparatus, this testing apparatus is without the need to water tank, easy to use, and automaticity is high, reduces workman's labor capacity, enhance productivity.
The purpose of this utility model realizes by following technical proposal: a kind of auto plastics oil sump testing apparatus, comprises base, frame, controller etc.Described base is fixed with support bar, and described supporting bar top is fixed with lower air cylinder, described in press down cylinder piston and connect slide plate, described slide plate is slidably enclosed within described support bar, and lower air cylinder controls slide plate and moves up and down along support bar.Fix a cylinder bottom described slide plate, cylinder piston is provided with plug, plug is for blocking the open bore on plastic oil pan.Be provided with depression bar bottom described slide plate, depression bar is used for the position of plastic oil pan to fix.Described base is provided with test board, chain connection in the middle part of described test board edge and several clamping bar, one end of described clamping bar is connected with the piston hinge of clamping cylinder, clamping bar is equivalent to lever, clamping cylinder piston stretches out and lifts clamping bar one end, the clamping bar other end will press down, thus is pressed on test board at oil sump edge.Described test board is provided with inflation inlet and gas pressure detector, as various gas pressure sensor, described inflation inlet connects charger.
The principle of work of this auto plastics oil sump testing apparatus is such, oil sump is tipped upside down on test board, inflation inlet and gas pressure detector are all covered by oil sump, controlling clamping cylinder is pressed on test board by oil sump edge, slide plate moves down, down-pressed pole pushes down oil sump, the position of oil sump is tentatively fixing, cylinder control plug stretches out to be blocked the opening port of oil sump, charger is inflated to certain pressure by inflation inlet in oil sump, then air feed is stopped to enter packing stage, at this moment gas pressure detector detects the pressure of gas in oil sump, if air pressure remains unchanged, explanation oil sump is air tight, if pressure reduces oil sump gas leakage is described gradually, control alarm equipment alarm.
In above-mentioned auto plastics oil sump testing apparatus, described clamping bar inside is provided with controlled electromagnet, and described electromagnet connects current controller, and described test board is placed with iron ball.At packing stage, the electric current controlling electromagnet changes magnetic force size, the shock oil sump thus control iron ball rolls in oil sump, the air-tightness of test oil drain pan under vibration operating mode.Because the gap structure sometimes due to little is special, air tight when housing is subject to uniform pressure, but may will leak gas in the case of vibrations.
In above-mentioned auto plastics oil sump testing apparatus, described slide plate is connected to the exterior bottom of a cover body, described cover body mouth down, described cover body mouth edge is provided with rubber layer, the cylinder of described depression bar and connection plug is fixed on the inside bottom of described cover body, described base is provided with inflation inlet and gas pressure detector, described inflation inlet connects charger.When slide plate glides, oil sump can cover together with test board by cover body completely, thus cover body and base form a closed space.Identical with above-mentioned Cleaning Principle, in cover body, fill the gas as certain pressure by the inflation inlet on base, utilize the gas pressure detector detected pressures situation of change on base, thus judge whether oil sump leaks.Because sometimes by the impact of leak shape or when having fragmentation but also do not leak, leakage situation can not be measured by oil sump internal pressurization, but find leakage during the pressurized of oil sump outside.
In above-mentioned auto plastics oil sump testing apparatus, be connected with telescoping mechanism between described depression bar and slide plate, as pneumatic cylinder, linear electric motors etc.Control the flexible to adapt to the shape bottom oil sump of telescoping mechanism, or utilize telescoping mechanism to beat at the bottom of oil sump, so that in the sealing vibrating test oil drain pan under operating mode.
In above-mentioned auto plastics oil sump testing apparatus, the gas piping of described clamping cylinder is communicating together.So that all clamping cylinders produce identical pressure.
In above-mentioned auto plastics oil sump testing apparatus, this equipment also comprises coder, and coder is used for qualified oil sump to stamp identification code.
Compared with prior art, this auto plastics oil sump testing apparatus has the following advantages:
1, the utility model is by forming closed space by oil sump and test board, and utilize pressurize to test impermeability, easy to operate, automaticity is high.
2, the utility model not only can be measured under the environment of oil sump by interior pressure, can also measure under by the environment of external pressure, and can also oil sump impermeability under measuring vibrations work condition environment, makes the reliability of measurement higher.
3, the utility model structure is simple, and easy to operate, cost is low, greatly can improve the bubble-tight detection efficiency of oil sump.
