Description
Technical field
The utility model relates to a kind of mechanical scanner that is used for the Ultrasonic Nondestructive instrument, is mainly used in the detection of circular arc pipe fitting and curved surface, can detect small diameter tube simultaneously.
Background technology
The product quality of Ultrasonic Nondestructive instrument in many industrial circles detects, there is irreplaceable vital role aspects such as device security performance inspection, one of them important component part is exactly mechanical scanner, being used to carry ultrasonic probe moves in the detected material surface, realization is to the ultrasonic scan of object to be detected, the existing machinery scanner comprises body frame and is connected the prolongation frame of body frame one side, described body frame is made of crossbeam and two longerons that are connected the crossbeam two ends, the two ends of described each longeron are provided with magnet-wheel mechanism, the magnet-wheel of described magnet-wheel mechanism connects support by magnet-wheel and is connected on the described longeron, because the longeron of existing scanner is straight, under the situation that magnet-wheel and other part dimension can not arbitrarily reduce, the span that lays respectively between two magnet-wheels at longeron two ends can not arbitrarily reduce, and therefore is difficult to adapt to the scanning to the less curved face object of the less pipe fitting of diameter or other radius-of-curvature.
The utility model content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of mechanical scanner that is used for the Ultrasonic Nondestructive instrument, is suitable for the scanning of other less curved face object of less pipe fitting of diameter and curvature.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of mechanical scanner that is used for the Ultrasonic Nondestructive instrument, comprise body frame, described body frame is made of crossbeam and two longerons that are connected to described crossbeam two ends, the two ends of described each longeron are provided with magnet-wheel mechanism, the magnet-wheel of described magnet-wheel mechanism connects corresponding described longeron by the magnet-wheel support, convex arc in the middle of described each longeron all is.
Because the utility model is arranged to arc with longeron, therefore the distance that is installed between the magnet-wheel at longeron two ends is shorter than longeron counterpart, when being used for less pipe fitting of scanning diameter or similar curved, two magnet-wheels with the distance between two contact points between the pipe fitting surface less than the distance between the two magnet-wheel axle center, reduced the angular distance between two contact points thus effectively, magnet-wheel can steadily be moved reliably on the less pipe fitting surface of diameter, avoided under the prior art because of two the magnet-wheels less pipe fitting surface of contact diameter or the defective that can not move reliably at the less pipe fitting surface-stable of diameter simultaneously, guarantee to detect the reliability of data, enlarged the accommodation of Ultrasonic Detection instrument.Simultaneously, this scanner does not change the one-piece construction of existing scanner and the structure of other each parts basically, have simple and compact for structure, dirigibility good, accuracy in detection and reliability advantages of higher, can be used for the detection than the pipe fitting and the similar curved object of minor diameter.
