The metal pipe testing device has the testing precision matching industry standard, and high testing speed, and the structure is simple to be manufactured.
Description
Technical field
The present invention relates to a kind of pick-up unit, particularly a kind of checkout equipment that is applied to industrial metal tube.
Background technology
Whether qualified the wall thickness accuracy of the production run middle tube body of the tubing in the auto parts machinery, the particularly horizontal degree of uniformity of wall thickness are very important index of tubing one.Often need adjust rolling technological parameter for improving the tubing qualification rate, therefore, tubular measurement is absolutely necessary.In the long-term production practice, people have constantly proposed some measuring methods, as: " laser one ultrasonic measurement system " of (1) German Man Naisiman Steel tube Co., Ltd development, it is to produce ultrasound wave by pulsed laser, by interfering to come Measuring Object thickness, be a kind of non-contact measurement.This method is just in the experimental phase, also not commercialization.This non-contact measurement not only has its application limit, and system is huge, complex structure, cost an arm and a leg; (2) " supersonic thickness meter ", domestic a large amount of at present portable supersonic thicknessmeters that use.This method generally is used for the thickness measure of steel plate.When being used for the measurement of steel pipe, there is the low problem of precision.Mainly be because the steel pipe profile is a right cylinder, ultrasonic meter is difficult to accurately locate along the normal direction of tube-surface, and certain angular deviation is arranged a little, will cause bigger measuring error; (3) destructive test method is a kind of manual measurement method that generally use at present steel pipe's production scene at home.It according to the certain size segmentation, along laterally dissecting into some equal pipeline sections, is measured with wall thickness micrometer gauge tested body to the pipeline section wall thickness, calculate average thickness again.This method is not only taken a lot of work but also time-consuming, also out of true.It belongs to destructive detection method, and the tubing after the measurement can not utilize again.
Chinese patent application, the patent No. 03204907.2, it has announced a kind of measurement mechanism of weldless steel tube wall thickness, is made up of bearing, main guide pipe and inside surface measuring mechanism, displacement transducer, computing machine four parts.Two bearings are installed in respectively on the chuck and centre frame of engine lathe, about tested steel pipe is packed between two bearings, main guide pipe penetrates the lathe spindle hole and is slidingly matched with the endoporus of bearing, links together with lathe saddle again by traction handle and assistant support; The inside surface measuring mechanism is installed in the main guide pipe, it be by be fixed on lever in the main guide pipe, vertically be installed on the main guide pipe and abut against tested steel pipe internal-surface interior chaining pin, be positioned on the lever and and constitute by the inside surface displacement transducer that assistant support links to each other with lathe saddle; The outside surface displacement transducer is positioned on the outside surface of tested steel pipe and with lathe saddle and is connected.For chaining pin in making and inside surface are close to, press-fit a spring at the tail end of interior chaining pin, spring places again in the thread bush, and thread bush is threaded with the tube wall of main guide pipe.In order to make the inside surface displacement transducer that is positioned on the lever, the detected surface of chaining pin height situation in truly reflecting, lever is that vertically the tube wall with main guide pipe is fixed together with an axle, between axle and the lever bearing is installed.Inside surface displacement transducer, outside surface displacement transducer by A heart converter input computer data acquisition system, can obtain the height variable signal of the steel pipe surfaces externally and internally of gained tubular delta data, and can be presented on the screen.Its operation more complicated of such device realizes difficulty.
Summary of the invention
The object of the present invention is to provide a kind of very easy detection to go out metal tube whether crooked checkout equipment is arranged.
In order to reach described purpose, checkout equipment provided by the invention, it mainly comprises a monitor station; Described monitor station is provided with light hole, and monitor station is provided with ruler, and described ruler below is provided with the cushion block that makes metal tube consistent with the ruler height, is provided with the detection lamp below the described light hole.
The length of above-mentioned light hole is consistent with ruler.
The length of above-mentioned detection lamp is consistent with the length of light hole.
Whether the pipe shaft that the present invention can detect metal tube very easily has bending, thereby total man worker detects and expensive pick-up unit before replacing.This checkout equipment accuracy of detection meets industry standard, and detection speed is fast, and structurally the present invention is simple simultaneously realizes easily.
Description of drawings
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a straight sectional drawing of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
The technical scheme that provides according to Fig. 1 and Fig. 2, this checkout equipment mainly is at monitor station 7 light hole 1 (see figure 2) to be set as can be known, on monitor station, be provided with simultaneously ruler 2 (see figure 1)s, this ruler position is at the edge of light hole, its length is consistent with the length of light hole, is provided with two cushion blocks 4 below ruler, and these two cushion blocks can make metal tube 3 highly consistent with ruler 2, detection lamp 5 (see figure 2)s that are provided with under the light hole are connected with monitor station 7 by support, and its length is consistent with light hole 1.
The equipment that obtains according to technique scheme is placed on the metal tube 3 of required detection on the cushion block 4 on the monitor station 7 in use, and itself and ruler 2 are close to, and justify align; Turn on and detect lamp 5, because this lamp is positioned at the below of light hole, then detect light that lamp sends and just can arrive slit 6 between ruler and the metal tube by light hole, as long as detection person is tight with pressing between ruler and the metal tube with hand, whether there is light to appear by the slit of observing between ruler and the metal tube, if have the side and the ruler of this metal tube of explanation inconsistent, defective, detection person detects the whole side of metal tube by the rotating metallic pipe simultaneously.
More than be one of embodiments of the present invention,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize purpose of the present invention equally for those skilled in the art.But this variation obviously should be in the protection domain of claims of the present invention.
