Technical Field
The utility model relates to a detect technical field, especially relate to a pipe fitting surface defect automatic checkout device.
Background
The special equipment such as the pipe fitting has various quality problems such as electric arc damage, welding beading, sinking, corrosion and the like in the manufacturing and using processes, and the detection of the surface defect of the pipe fitting is the basis of the quality evaluation of the pipe fitting and the reliability evaluation of the pipe fitting and is also the basis for improving the manufacturing quality and the service performance of the pipe fitting.
According to the specification of NB/T47013-2015 pressure-bearing equipment nondestructive testing, the surface defects of the pipe fitting are mainly divided into the existing defects and the circular defects. The grade of the surface defect of the pipe fitting needs to be divided according to parameters such as length, size, area and the like of the defect. In actual detection, mostly the manual work snatchs the pipe fitting and observes to judge its surface defect position, and need use the measuring tool of corresponding precision, carry out defect grade to it and judge. The industrial camera is combined with the rotating device and the clamping device to shoot the defects on the whole surface of the pipe fitting, and then the programming of a software program is combined, so that the positioning and quantitative evaluation of the defects on the surface of the pipe fitting can be realized, and the automatic detection of the defects on the surface of the pipe fitting is realized.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
Fig. 1 is an overall structure of an automatic detection device for surface defects of pipe fittings, which comprises: the system comprises a rotating module, an image acquisition module, a pipe fitting to be tested 106, a pipe fitting to be tested clamp and a frame box 101; the rotating module is arranged at the bottom of the automatic detection device; the pipe to be tested is arranged on the rotating module through the pipe clamp to be tested; the image acquisition module is fixed on the frame box body through a fixing device; the rotation module comprises a rotation stage 105 and a motor 107; the pipe fitting clamp to be tested comprises a three-jaw chuck 103 and a flange 104; the image acquisition module includes three industrial cameras 102.
The rotating platform 105 is fixed on the bottom tray of the frame box 101 by a fixing device and is connected and driven to rotate by a motor 107. Drive its according to regulation angle rotation, pause through the motor, to every pipe fitting that awaits measuring, the revolving stage is guaranteed the accumulative rotation at least and is reached 360, makes the whole surface of pipe fitting all gathered by the camera.
The three-jaw chuck 103 is fixed on the rotary table 105 through a flange 104 and a fixing device, and is used for clamping a pipe fitting 106 to be tested, so that the pipe fitting can be in a stable and upright state in the rotating process and the pause.
One industrial camera is fixed on a top cover plate of the frame box body 101 through a fixing device, the other industrial camera is fixed on a side baffle of the frame box body 101, and the other industrial camera is fixed on a bottom tray of the frame box body 101 and is used for shooting outer surface images of the upper portion, the side wall and the bottom of the pipe fitting from the upper side, the side edge and the bottom respectively. After the pipe fitting is rotated by a fixed angle and stabilized as required, the three industrial cameras start to shoot simultaneously, after the shooting is finished, the pipe fitting can start to rotate next time, all photos collected by the cameras are uploaded to a computer to be stored, and the compiling of a software program is combined, so that the positioning and quantitative evaluation of the surface defects of the pipe fitting are realized, and the purpose of replacing manpower to carry out automatic detection on the surface defects of the pipe fitting is achieved.
The working process of the embodiment is as follows: firstly, a motor drives a rotating platform to rotate by a fixed angle as required, and the rotating platform drives a pipe fitting to be tested to regularly rotate through a three-grab chuck and then is static and stable; three industrial cameras at different positions shoot images of the outer surface of the pipe fitting at the same time; repeating the first working step and the second working step, ensuring that the pipe fitting rotates at least for one circle completely, and enabling the industrial camera to shoot the whole outer surface of the pipe fitting completely; and fourthly, transmitting all the collected pictures to a computer, and detecting the position and the size of the surface defect of the pipe fitting by using a computer program.
Although the embodiments of the present invention have been described above, the description is only for the convenience of understanding the present invention, and the present invention is not limited thereto. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
