Description
Technical field
The present invention relates to plastic pipe quality testing field, in particular, is related to a kind of plastic pipe inner diameter measurement dress
Put.
Background technology
At present the annual rate of growth in Material of Plastic Tube in Our Country market occupies the first in the world up to 15%, and Plastics in China tubing market has
Huge growing space.However, due to plastic pipe wide market so that enterprise enters one after another, relatively low access door
A series of problems, such as sill cause irregular marketing, therefore competitive pressure is very huge.Solve what plastic pipe enterprise faced
Predicament, the task of top priority is that requirement enterprise itself makes the best of one's way the road improved quality as first substantial improvements, but existing plastic pipe chi
Very little detection typically adopts manual measurement, inefficiency, and manual detection to there is the not high situation generation of accuracy of detection unavoidably, therefore
The quality of product cannot be effectively ensured.
The content of the invention
It is an object of the invention to provide a kind of novel maglev type plastic pipe inside diameter detection device of structure is realizing replacing
For manual measurement, ensure certainty of measurement, improve detection efficiency.
A further object of the present invention is to propose a kind of detection method of maglev type plastic pipe inside diameter detection device.
A kind of maglev type plastic pipe inside diameter detection device, including electric magnet, the logical detent plug of magnetic suspension, for gathering magnetic suspension
Position sensor, retractor device, the controller of logical detent plug position signalling；The electric magnet is arranged on retractor device, and position passes
Sensor is arranged on electric magnet, and controller is electrically connected with electric magnet, position sensor；The retractor device band motor magnet makees line
Property stretching motion；The logical detent plug of the magnetic suspension is suspended in below electric magnet after electric magnet energization；The controller is used to control
The magnetic field intensity of electric magnet and the data of processing position sensor acquisition.
Preferably, the electric magnet carries even number of poles, and each pair magnetic pole is symmetrical expression arrangement, is wound with each magnetic pole
Coil.The number of turn of coil of the present invention sets according to the quality size of the logical detent plug of magnetic suspension.
Magnetic field in the present invention on alive circular coil produced by every a bit of electric current, all points to same in coil
One direction, therefore the magnetic field in coil is big compared with the magnetic field intensity that straight wire electric current is produced, and the electric current of circular coil is bigger, radius is healed
Little, then the magnetic field intensity at hub of a spool is i.e. bigger, and the controller controls electromagnetism by electric current on control electromagnet coil
The magnetic field intensity of ferrum.
The logical detent plug of magnetic suspension follows retractor device during moving to plastic pipe, when one part is entered in tubing
When, the magnetic force suffered by it will reduce, now by controller come the size of current in regulating magnet coil increasing magnetic field
Intensity, can just keep the suspended state of the logical detent plug of magnetic suspension.Said process can also be by increasing adaptation function to controller
To realize.
Preferably, the two ends of the logical detent plug of the magnetic suspension are spheroids, and mid portion is cone table；Detent plug two ends are led in magnetic suspension
Spheroid there are different diameters.The different spheroid of two diameters is embedded in the magnetcisuspension that the two ends of a cone table constitute the present invention
Floating logical detent plug, the logical detent plug of the magnetic suspension can be by attraction.
A kind of detection method of application maglev type plastic pipe inside diameter detection device, comprises the following steps：
S1：Electric magnet is powered, and the logical detent plug of magnetic suspension is suspended in the lower section of electric magnet；
S2：Moving telescopic device so as to which band motor magnet makees stretching motion toward plastic pipe pore direction；
S3：The position signalling of the logical detent plug of position sensor Real-time Collection magnetic suspension is simultaneously sent to controller and is processed；
S4：Controller is judged whether the plastic pipe for measuring is qualified by default criterion.
Judge the qualified criterion of plastic pipe internal diameter as：D/2≤L ＜ D/2+d/2+H；Judge that plastic pipe internal diameter is less than normal
Criterion be：0≤L ＜ d/2；
The diameter of the spheroid that wherein D is relatively large in diameter in the spheroid for the logical detent plug two ends of magnetic suspension, d is the logical detent plug two of magnetic suspension
The less sphere diameter of diameter in the spheroid at end, H is the width of the logical detent plug cone table of magnetic suspension, and L is collected for position sensor
The logical detent plug of magnetic suspension the length that enters in expects pipe material of the logical detent plug of position signalling-magnetic suspension.
When the logical detent plug of magnetic suspension fully enters plastic pipe, position sensor does not have displacement signal data output to show modeling
The internal diameter of expects pipe material is bigger than normal, and plastic pipe is unqualified.
If the small end spheroid of the logical detent plug of magnetic suspension can be entered in plastic pipe, and moves to big end spheroid and centre always
Cone table junction is just obstructed can not advance, and the internal diameter for now indicating that plastic pipe deducts small end spheroid in big end sphere diameter
In the margin of tolerance of diameter, now just explanation plastic pipe is qualified.
If the logical detent plug of magnetic suspension to plastic pipe when moving, just it is obstructed not in small end spheroid and middle cone table junction
When can advance, illustrate that the internal diameter of plastic pipe is too little, plastic pipe is unqualified.
If the small end spheroid of the logical detent plug of magnetic suspension and big end spheroid can pass through the internal diameter of plastic pipe, whole magnetcisuspension
Floating logical detent plug is just capped, and position sensor cannot export the logical stop bit shifting signal of magnetic suspension, now illustrate plastic pipe
Internal diameter is too big, and plastic pipe is unqualified.
Relative to prior art, the invention has the beneficial effects as follows：Fast and accurately the internal diameter size of plastic pipe can be entered
Row detection, the not high situation of the accuracy of detection existed when effectively reducing manual detection occurs, and the quality for making product is guaranteed, and has
There are good economic results in society.
