step one: the method comprises the steps that a stainless steel pipe needing to be subjected to size detection is inserted into a three-rotation chuck (6) after penetrating a guide pipe (8), the stainless steel pipe main body is fixedly clamped through the three-jaw chuck (6), meanwhile, a bidirectional threaded rod (9) is driven to rotate through a rotation adjusting bolt (15), a moving plate (10) at two ends is driven to move towards the middle through rotation of the bidirectional threaded rod (9), a connecting rod (11) is driven to synchronously move through movement of the moving plate (10), an arc limiting plate (12) is driven to move at the same time, the roller shaft (13) is enabled to be in contact with the surface of the stainless steel pipe main body through movement of the arc limiting plate (12), rotation of the bidirectional threaded rod (9) is stopped after the roller shaft is in contact, and meanwhile, a detection probe of a size detector (25) is in butt joint with the surface of the stainless steel pipe main body;
step two: after clamping and fixing are finished, the driving motor (2) is started to drive the first belt pulley (3) to rotate through the output shaft, the first belt pulley (3) is rotated to drive the second belt pulley (26) and the third belt pulley (27) through the belt (28), the rotation of the second belt pulley (26) drives the threaded rod (16) to synchronously move, the rotation of the threaded rod (16) drives the moving block (17) to synchronously move, and meanwhile, the moving block (17) moves to drive the balance plate (20) to synchronously move along the second guide rod (18) through the guide block (19);
step three: the rotation of the third belt pulley (27) drives the transmission rod (5) to rotate, and simultaneously drives the three-jaw chuck (6) to synchronously move, and the rotation of the three-jaw chuck (6) drives the stainless steel pipe main body to stably and synchronously rotate through the roll shaft (13);
step four: the rotation of stainless steel pipe main part and the slow movement of balance board (20) make the circumference surface of stainless steel pipe main part and the detection probe of size detector (25) carry out uninterrupted contact, carry out the monitoring processing of the circumference size of stainless steel pipe main part through size detector (25), the opening of light source (23) is polished the illumination to stainless steel pipe main part simultaneously, detect the processing to the surface of stainless steel pipe main part through industry camera (22) simultaneously, the relevant data information of industry camera (22) and size detector (25) detection is sent to the display.
