Description

Technical Field

[0001] The invention relates to the technical field of shaft rod workpiece straightening, and in particular to a straightening machine. Background Art

[0002] People have higher and higher requirements for the straightening accuracy and detection technology of shaft rod workpieces. In view of the bending deformation of various shaft rod workpieces during the production process, the straightening machine usually needs to be equipped with multiple sets of support modules, and the corresponding support positions on different workpieces will also be different. Therefore, it is necessary to adjust the position of the support module according to different workpiece models. Usually, the position of the support module is adjusted manually. First, the debugger needs to rely on his personal practical experience to judge the approximate support position of the support module for different workpieces, and then manually move the support module to the approximate position, manually lock the support module to the straightening platform, and finally perform the straightening operation. If the straightening effect is not as expected, it is necessary to repeat the above measurement, movement, locking and straightening process until the support module is adjusted to the appropriate position to achieve the expected straightening effect. This process requires the debugger to repeatedly measure, move, lock and straighten, which is inconvenient to adjust, time-consuming and labor-intensive, and the manual operation positioning accuracy is low, which reduces the straightening efficiency.
