Abstract
The invention discloses a device detecting air tightness of a wheel hub and an application method of the device. The device detecting air tightness of the wheel hub comprises a conveying device, a transmission device, a sealing device and a detector which are successively arranged; wherein the detector comprises an ionization chamber, a first magnetic field, a second magnetic field and a sensor which are successively arranged. A detecting method is that transversally conveying the wheel hub into a sealing device, after compacting and sealing, injecting inert gases into the sealing device; if the wheel hub does not have air leakage, then no gases can escape from the sealing device; if the wheel hub have air leakage, then the inert gases escape from the sealing device and flow into the ionization chamber to be ionized into charge particles, the charge particles flow into the sensor from the first magnetic field and the magnetic field in directional mode, and the sensor sends out alarming signals. The device detecting air tightness of the wheel hub and the application method of the device have the advantages that the air tightness and the detecting method are full-automatic methods, wheel hub air leakage is informed through alarming rather than eye judging, the detecting technology is more reliable and stable, data are easy to be recoded and performed with statistics, detecting efficiency is high, and worker labor intensity is lowered.
Description
Technical field
The present invention relates to the bubble-tight equipment of a kind of detection wheel hub and application process thereof, belong to the detection technique field.
Background technology
Aluminium alloy wheel hub impermeability detection technique, conventional art is the close detection of aqueous vapor, be that bubble leaks method, it detects principle is that aluminium alloy wheel hub is inboard by external force, the outside is sealed with sealing pad, then wheel hub and sealing pad are immersed in the water, and are filled with the atmospheric pressure of 0.5mpa, if wheel hub has small opening, gas can go out to leak out gas from small opening, forms bubble in water.It is also simple that this mode detects principle, also is widely used.Shortcoming is to judge roughly by artificial according to the formation speed of Air Bubble Size, form and bubble, and detection time is long, can not adapt to the requirement of modern automobile industry development.
Summary of the invention
The objective of the invention is provides the bubble-tight equipment of a kind of detection wheel hub and detection method to solve the problems referred to above in order to solve the defective of the existing poor accuracy of wheel hub impermeability detection in prior art.
To achieve these goals, technical scheme of the present invention is as follows:
The bubble-tight equipment of a kind of detection wheel hub is characterized in that, comprising: the conveyer that sets gradually, packoff and detecting device, wherein, described detecting device comprises ionization chamber, the first magnetic field and the second magnetic field and the sensor that sets gradually.
In the present invention, described packoff comprises an air admission hole and a venthole, and described air admission hole is arranged on the top of packoff, and described venthole is arranged on the sidewall of packoff.
In the present invention, described the first magnetic field is provided with adjustable pilot hole.
In the present invention, described sensor is gas sensor.
Using the standby bubble-tight method of wheel hub that detects of installing of the present invention, is that wheel hub is laterally sent in packoff by conveyer, and after press seal, inert gas injecting in the packoff if wheel hub is air tight, is overflowed in packoff without gas; If wheel hub gas leakage, inert gas is overflowed from packoff, flow in ionization chamber and be ionized into charged particle, described charged particle continues to flow in the first magnetic field, under the Lorentz force effect in magnetic field in directed movement to the second magnetic field, in flow sensor behind the second magnetic field, send alerting signal by sensor.
Advantage of the present invention is: this air tightness detection equipment and detection mode are full automatic methods, not with the naked eye to go judgement, but inform wheel hub gas leakage with reporting to the police, its detection technique is more reliable and stable, data easily record statistics, detection efficiency is high, labor strength reduces.
