[0024] By means of the inductive sensor 603, which is an existing distance sensor, model reference: CS-3L300, the commanding height of each bend of the workpiece 7 to be straightened can be measured, and the existing control principle is used to make the push cylinder 601 drive the support head 602 to move, so as to provide fitting support for the bend, and the push cylinder 601, the support head 602 and the inductive sensor 603 are independently provided in multiple groups, so as to be able to independently adjust and support different bending parts of the long-axis workpiece 7, to ensure the stability of the workpiece 7, and to avoid the workpiece from naturally sagging under the action of gravity, resulting in inaccurate bending amount measured for the workpiece and difficulty in precise straightening. By moving the gantry 3, the straightening cylinder 4 and the support seat 5 can be driven to move left and right on the workbench 2, and with the extrusion force of the straightening cylinder 4 and the support seat 5, each point can be straightened in turn when moving to the bent part after detection;

[0025] like Figure 1-Figure 5 As shown, fixing mechanisms 8 for pressurizing and tightening are installed at both ends of the body support 1, and the fixing mechanism 8 includes a movable push cylinder 801 and a telescopic cylinder 802, and the telescopic cylinder 802 is installed at the upper end of the movable push cylinder 801, and the fixing mechanism 8 also includes a pressure head 803, and the front end of the telescopic cylinder 802 is installed with a pressure head 803.
