and judging whether the sizes of all parts of the detected bearing ring (7) meet the requirements or not through the computer (2), and blanking according to the detection result.
9. The dimension detection method for bearing ring machining according to claim 8, characterized in that: the size of each position of the bearing ring (7) in rotation is detected by using a detection piece (5), and the device comprises:
detecting the thickness of the bearing ring (7) rotating by using a double crystal straight probe (52);
and detecting the distance from the detection piece (5) to the inner wall of the bearing ring (7) opposite to the detection piece when the bearing ring (7) moves by using a laser probe (51).
10. The dimension detection method for bearing ring machining according to claim 8, characterized in that: judge through computer (2) whether size everywhere of bearing ring (7) that detects meets the requirements to carry out the unloading according to the testing result, include:
signals detected by the double-crystal straight probe (52) and the laser probe (51) are processed into numbers by a processor of the computer (2);
judging whether the obtained number is within a preset range;
if the material is in the preset range, the first conveying belt (91) is used for blanking;
if the current is not within the preset range, the second conveyer belt (93) is used for blanking.
