Abstract
The invention discloses a steel pipe end roundness detection system comprising a detection unit used for detecting displacement data information and rotation angle information of movement of a steel pipe and image information of the end of the steel pipe, a driving device used for driving the steel pipe to move, and a processing unit used for receiving the data information of the steel pipe transmitted by the detection unit, processing the received information and calculating the diameter error of the steel pipe. According to the steel pipe end roundness detection system disclosed by the invention, the detection unit is adopted to acquire an image of the end of the steel pipe and the driving device is adopted to move the steel pipe by a certain angle to a certain position, then, the detection unit detects the angle information and displacement information of the movement of the steel pipe and transmits the detected data information to the processing unit, and finally, the processing unit processes the received data information and calculates and judges the diameter error of the detected steel pipe and the roundness error of the end of the detected steel pipe.
Description
Technical field
The present invention relates to a kind of steel tube end part system for detecting roundness.
Background technology
Man-hour will be carried out thickening process adding in the end of the firm pipe of oil well, and two ends carry out adding bulk processing in a heated state.The steel pipe two ends diameter of such thickening is different from mid diameter, cause steel pipe must carry out detorsion in follow-up process, the detection system of the steel tube end part of prior art is mostly artificial orthosis, utilize and manually carry out rotating and manual measurement, error can be there is when detecting like this, and testing result is slower.
Summary of the invention
According to prior art Problems existing, the invention discloses a kind of steel tube end part system for detecting roundness, comprise the detecting unit of the image information for examination steel tube moving displacement data message, rotational angle information and steel tube end part;
The drive unit moved for driving steel pipe;
And receive the data message of the steel pipe that detecting unit transmits, the information received is processed, calculates the processing unit of diameter of steel tube degree of error.
Under duty: utilize drive unit drive the certain displacement of steel pipe movement and rotate certain angle value, described detecting unit detects the data message that this steel pipe moves, and measure this steel tube end part radian, rotational angle data message and testing result is sent to processing unit.
Described detecting unit comprise for examination steel tube moving displacement data message displacement transducer and for examination steel tube rotate angle information angular transducer and to the end of steel pipe carry out make a video recording process video camera.
Described processing unit comprises receiving the scrambler that data message carries out process computing and the diagnostic module diagnosed data message and calculate.
Steel tube end part system for detecting roundness disclosed by the invention, detecting unit is utilized to carry out image acquisition to the end of steel pipe, utilize drive unit to steel pipe movement certain angle and certain position, then detecting unit is utilized to detect angle information and the displacement information of its movement, again the data message detected is sent in processing unit, processing unit processes the data message received, calculate, judge this detected diameter error of steel pipe and the deviation from circular from of steel tube end part.
