Abstract
The utility model discloses a tool for detecting the tightness of an automotive tube. The tool comprises a sleeve, a rubber ring, through holes, a steel ring and a gas-filling pin, wherein one end of the sleeve is a round opening, the rubber ring is arranged in the sleeve, the through hole is arranged on the rubber ring, the diameter of the through hole is equal to the diameter of the round opening of the sleeve and also equal to the external diameter of the rubber tube. The steel ring is arranged on the other end of the sleeve, and the rubber ring is fixed in the sleeve. A through hole is arranged on the steel ring to allow the gas-filling pin to pass through. The tool solves the problem of the prior art that when the tightness of the automotive oil tube is detected at high pressure, a quick-insert male joint ejects out and does not block the tube, so that the enough bite force is ensured when the tightness of the automotive tube is detected at the high pressure, and simultaneously the oil tube is not damaged.
Description
Technical field
For detection of a frock for automobile oil pipe sealing, the specifically detection to oil pipe sealing under high-pressure situations.
Background technology
The performance of automobile oil pipe comprised a lot, and property indices is all in order to guarantee that in use oil pipe can smooth and easy logical oil.Wherein, the sealing of automobile oil pipe is just important especially, when detecting oil pipe sealing property, oil pipe is sealed at both ends, is sold in oil pipe and is inflated, the sealing of test oil pipe by inflation.In conventional operation, tend to cause the gas leakage of sealed port even sealing-plug to be ejected because aeration quantity is excessive, cause testing.
Utility model content
For traditional test automobile oil pipe sealing, especially during Hi-pot test, sealed end can not be fixed on the problem in oil pipe, the utility model proposes a kind of frock for detection of automobile oil pipe sealing.
This frock has comprised sleeve, rubber ring, steel ring and inflation pin, its middle sleeve one end is for being provided with circular open, rubber ring is placed in sleeve, rubber ring is provided with through hole, through-hole diameter and sleeve circular open equal diameters, steel ring is located at the sleeve other end, and rubber ring can be fixed in sleeve, steel ring is provided with through hole simultaneously, inflation pin can be passed, the inner circumferential surface of described rubber ring has the lines of ridge shape, and larger friction force can be provided at work, prevents the disengaging of oil pipe and frock.
Further, at the two ends of rubber ring, be respectively provided with a rubber sheet gasket, this rubber sheet gasket can provide the environment of better sealing, and while preventing from testing, the gas leakage of sealed end, makes test result more accurate.
Further, at sleeve, be provided with cylinder outward, cylinder operation drives sleeve extruding rubber ring, makes rubber ring produce the seal of deformation extruding oil pipe, makes sealing effectiveness better.
Further, this frock is provided with work top, more convenient while making to test.
Accompanying drawing explanation
Shown in Fig. 1, it is this tool structure schematic diagram.
Shown in Fig. 2, it is rubber ring inside surface ridge shape texture maps.
Embodiment
Shown in Fig. 1, frock has comprised sleeve 1, rubber ring 2, steel ring 3 and inflation pin 4, its middle sleeve 1 one end is for being provided with circular open, rubber ring 2 is placed in sleeve 1, and rubber ring 2 is provided with through hole, through-hole diameter and sleeve circular open equal diameters, steel ring 3 is located at sleeve 1 other end, and rubber ring 2 can be fixed in sleeve 1, steel ring 3 is provided with through hole simultaneously, inflation pin 4 can be passed.The overall diameter of inflation pin 4 equals the interior diameter of oil pipe to be tested.
During test, oil pipe is through the through hole of sleeve 1 and rubber ring 2, and the through hole of inflation pin 4 inserts oil pipe, opens cylinder 6, and cylinder 6 band moving sleeves 1 are extruding rubber ring 2 inwardly, and rubber ring 2, owing to being squeezed, produces deformation, has mainly occurred to stretch in the expansion of radial direction.Insert like this oil pipe of inflation pin and the connection of inflation pin is more firm, meanwhile, because the inner periphery of rubber ring 2 exists the lines of ridge shape, there is certain friction force with oil-pipe external wall.
In order to make better tightness, at the two ends of rubber ring 2, respectively established rubber sheet gasket 5, make the sealing property at two ends better, guarantee not occur the phenomenon of gas leakage in tool structure.
The motion of sleeve 1 is driven by cylinder 6, and cylinder 6 is bled or inflated, with the indentation of moving sleeve 1, thus compression or the recovery of drive rubber ring 2.
In order to make frock test process more convenient, be equipped with a worktable.
