However, the first clamp driving member D0 serves as a driving member, and the second clamp driving member E0 serves as a driven member.

In specific implementation, the runout detection mechanism F0 may employ a displacement sensor to detect the rotary runout of the workpiece surface, so as to analyze the runout of the workpiece for subsequent automatic pressure alignment.
Two clamping driving mechanisms D0 and E0 are fixed on the upper surface of the sliding table B2 through bolts, a clamping cylinder D7 acts to push out and drive a rotary center D12 on a rotary platform D8 and the tail end of an encoder to be respectively clamped and connected to two ends of a workpiece G0, then a servo motor D9 on the rotary platform D8 of the first clamping driving part D0 rotates to clamp and fix the workpiece G0 to perform rotary motion around the axis of the workpiece.

After the jumping data is obtained through detection, the bending position of the workpiece G0 is obtained, the sliding table driving mechanism C0 drives the workpiece G0 to move to a preset position, so that the bending position of the workpiece G0 is located right below a pressure head mechanism A4 of a driving hydraulic cylinder A2, and meanwhile, the servo motor D9 of a first clamping driving mechanism D0 is driven to drive the workpiece G0 to rotate, so that the bending position of the workpiece G0 faces to be located at the upper part, namely, is bent upwards; then the clamping cylinders D7 of the two clamping driving mechanisms D0 and E0 retreat to release the two ends of the workpiece G0, and the workpiece G0 is not clamped any more and falls onto the two supporting blocks A3. At the moment, the external hydraulic system drives the hydraulic cylinder A2 to drive the pressure head mechanism A4 to press down to the middle bending position of the workpiece G0, so that the workpiece G0 is bent and straightened. After the single straightening is finished, the two clamping driving mechanisms D0 and the clamping cylinder D7 of the E0 push out again to clamp the fixed workpiece G0, and the floating cylinder D6 pushes up to lift the workpiece for subsequent rotation run-out measurement. Through the steps, the equipment can realize automatic jumping measurement and pressure straightening correction of the workpiece.
The working process of the invention is as follows:
as shown in fig. 10, in the measuring state, the hydraulic cylinder a2 is retracted, the ram mechanism a4 is raised, and the slide B2 is located at the middle of the horizontally moving slide member B0. The clamping cylinder D7 is pushed out to make the head conical surface of the rotating centre D12 match with the centre holes at two ends of the workpiece G0. The floating cylinder D6 pushes the rotary platform D8 to be lifted, and the axle center of the workpiece G0 is slightly higher than the axle center of the arc groove on the upper surface of the supporting block A3. The runout detecting mechanism F0 measures the revolution runout of the workpiece. The servo motor D9 rotates to drive the workpiece G0 to carry out rotary run-out measurement.
As shown in fig. 11, in the stage where the slide table is shifted to be loaded, the slide table B2 is moved to the control program preset loading position. The floating cylinder D6 retracts to make the rotary platform D8 fall down, and the clamping cylinder D7 retracts to make the head conical surface of the rotary centre D12 and centre holes at two ends of the workpiece G0 relatively far away. The runout detecting mechanism F0 measures the revolution runout of the workpiece. Final work piece G0 landed on support block A3. Waiting for the load to proceed.
In the loaded condition to straighten the workpiece, floating cylinder D6 remains retracted and clamp cylinder D7 remains retracted, as shown in fig. 12, to prevent the pivot point D12 from interfering with the workpiece G0. The runout detecting mechanism F0 measures the revolution runout of the workpiece. The workpiece G0 falls on the supporting block A3, and the hydraulic cylinder A2 pushes out to enable the pressure head mechanism A4 to descend slowly, so that pressure is provided to bend the workpiece G0 gradually, and therefore pressure straightening is achieved.
