The invention discloses a
system for automatically detecting the expanding amount of a tube on a
heat exchanger tube plate. The
system comprises a base, a
robot, a
robot control cabinet and an industrial
personal computer, a
tail end shaft of the
robot is fixedly connected with a bias plate, and the bias plate is fixedly provided with a global camera, a local camera and a
laser range finder; a shell is connected to the offset plate, an anti-rotation sleeve and a cover plate are sequentially and fixedly arranged at the front end of the shell, a
linear motor is fixedly arranged on the rear side of the shell, an electric push rod of the
linear motor is fixedly connected with a convex cone, a concave cone is arranged on the front side of the convex cone and comprises an anti-rotation sliding block and a connecting shaft, a groove is formed in the rear side of the anti-rotation sliding block, and the anti-rotation sliding block is arranged in an anti-rotation hole of the anti-rotation sleeve in a sliding mode. The connecting shaft penetrates through the cover plate in a sliding mode, an inner
diameter gauge offset block is fixedly connected to the connecting shaft, and an inner
diameter gauge is arranged on the inner
diameter gauge offset block. The invention further discloses a method for automatically detecting the expanding amount of the tube on the
heat exchanger tube plate. According to the invention, systematization,
automation and intellectualization of detection are realized, manpower is saved, wrong detection and missing detection caused by human factors can be avoided, the accuracy of measurement data is ensured, and the detection precision and the detection efficiency are improved.
