The type of drive of described driving mechanism is gear-rack drive.Certainly, also can adopt other type of drive.
The present embodiment course of work and operation principle are as follows:
(1) workpiece is ajusted: centering body 10 and tensioning mechanism 11 actions, workpiece automatic centering is ajusted.
(2) profile scanning: mobile platform 2 drives workpiece by portal frame 5, detects workpiece appearance and size by the profile scanning sensor 14 on portal frame 5.
(3) proofread and correct: control system 9, first according to the data of workpiece appearance and size, is analyzed workpiece deformation situation, and then sent corresponding fill order to hydraulic system 6.
Distortion for workpiece evagination, oppositely support cylinder 13 first oppositely props up workpiece, then by the main correction oil cylinder I 7 compressive strain positions on portal frame 5, correcting deformed, the correction amount of being pressed into of main correction oil cylinder I 7 is controlled according to the size of workpiece deformation automatically by control system 9.
Distortion for workpiece indent, oppositely support cylinder 13 first oppositely props up workpiece, then the aspectant main correction oil cylinder I 7 of the required correction of workpiece on portal frame 5 is moved to and is close to workpiece, on inside workpiece cantilever beam 4, the main correction oil cylinder I 7 of stretching out on portal frame 5 is withstood by the outer wall of workpiece in one end of main correction oil cylinder II 12, other end top workpiece deformation face, correcting deformed, the correction amount of being pressed into of main correction oil cylinder II 12 is controlled according to the size of workpiece deformation automatically by control system 9.
In trimming process, the concrete data that relate to have: deflection, elastic deformation amount and the correction amount of being pressed into.
Wherein, deflection is for workpiece, defect, and its numerical value is detected and obtained by profile scanning sensor 14; Elastic deformation amount's index arm cylinder can be recovered the maximum amount of being pressed into of original form after pressing, every kind of arm cylinder only has data, and these data are inputted by people; What the correction amount of being pressed into was said is relative datum, equals the actual amount of being pressed into and deduct elastic deformation amount on numerical value, and this correction amount of being pressed into can just make the distortion of arm cylinder be corrected.Proofreading and correct oil cylinder elongation is: oil cylinder pressure head is to the mean value of the distance+elastic deformation amount's of arm cylinder benchmark+nearest apart from deflection the correction amount of being pressed into.
(4) check size: after all point calibrations that need to proofread and correct are complete, workpiece by portal frame 5, detects workpiece appearance and size by profile scanning sensor 14 again, if workpiece appearance and size is qualified, make mobile platform 2 return origin-location, unclamp centering body 10 and tensioning mechanism 11, hang away workpiece; On the contrary, again proofread and correct, until qualified.
