[0003] The existing method of determining the local bending position or multiple small bending positions of the lead screw is mainly manual straightening, and the bending position is manually determined. Testing does not meet actual production needs
However, the existing automatic straightening machine is suitable for the overall bending of the lead screw, and still requires manual participation. The straightening effect is judged by visual inspection, which is inefficient and prone to misjudgment and missed judgment.

The invention relates to the technical field of image processing, in particular to a lead screw bending positioning and straightening method and system. According to the method, the abnormal degree of the screw rod is judged according to the difference between the spectrum texture feature and the standard texture feature in the spectrum image. And determining a curved screw image according to the abnormal degree. And analyzing the edge pixel points of the curved screw image to obtain the crest edge and the crest edge length sequence. And taking the qualified screw crest width as a standard to obtain an abnormal value in the crest edge length sequence, and obtaining the maximum bending position through the position of the abnormal value. And the bending degree is further obtained according to the abnormal value and the tooth top width and the tooth bottom width of the qualified screw rod. And according to the bending degree, operating parameters of the lead screw straightening machine are controlled, and the maximum bending position is straightened. Automatic lead screw bending detection is achieved through frequency spectrum image features and camera imaging features, and a straightening machine is reasonably controlled according to the bending degree.
Description
technical field [0001] The invention relates to the technical field of image data processing, in particular to a method and system for bending, positioning and aligning a lead screw. Background technique [0002] During the production process of the lead screw, due to the influence of the parameters of the manufacturing equipment, the lead screw is prone to bending. Therefore, in addition to the blank process in the production process of the lead screw, straightening is required in the roughing and semi-finishing stages to reduce the curvature of the workpiece and make the machining allowance uniform. [0003] The existing methods for determining the local bending position of the lead screw or multiple small-scale bending are mainly manual straightening, and the bending position is determined manually. Inspection can not meet the actual production needs. However, the existing automatic straightening machine is suitable for the overall bending of the lead screw, and still r...
