A Bidirectional Correction Device for Incomplete Circular Workpieces

Abstract

The invention discloses a rotary driving mechanism and a bidirectional correction device for an incomplete arc workpiece. The rotary driving mechanism is used for enabling the whole bidirectional correction device to move around the incomplete arc workpiece and comprises a driving device, a bearing seat, two guide rails and a plurality of bearings. The bearings are fixed at the bottom of the bearing seat, and first V-shaped grooves are formed in the outer lateral walls of the bearings. The circle centers of the two guide rails are the same, the radiuses of the two guide rails are different, and V-shaped flanges matched with the first V-shaped grooves are arranged on two opposite side faces between the two guide rails. The bearings are accommodated between the two V-shaped flanges at the ends of the two guide rails through the first V-shaped grooves, so that the bearings are clamped between the two guide rails and can be guided to move by the two guide rails. The driving device is provided with a first gear, a second gear meshing with the first gear is arranged on the outer lateral wall of the most peripheral guide rail, the driving device can drive the bearings to slide on the two guide rails through meshing transmission of the two gears, and the bearing seat can be driven to move finally.

Description

technical field [0001] The invention relates to a rotary drive mechanism of a bidirectional straightening device, in particular to a bidirectional straightening device for a non-complete circular arc workpiece. Background technique [0002] Incomplete arc-shaped workpieces are mainly used for connecting multiple sections of aircraft cabins and rocket fuel storage tanks. They are mainly made of L-shaped cross-section aluminum alloy profiles. However, due to the phenomenon of material springback, the surface of the workpiece is prone to wrinkles and bulges after bending. And other defects, it is necessary to manually perform local percussion correction on the bulge and folds. Due to the large size of the workpiece, the manual percussion correction workload is large, and the processing quality and accuracy are guaranteed. Contents of the invention [0003] In view of the above-mentioned technical defects, the present invention provides a two-way straightening device for incom...

Problems solved by technology

[0003] In view of the above-mentioned technical defects, the present invention provides a two-way straightening device for incomplete arc-shaped workpieces. Its rotary drive mechanism can facilitate the two-way straightening device to make the whole two-way straightening device surround the Back to the non-complete arc-shaped workpiece movement, so that the two-way correction device can easily replace the manual correction of the surface defects of the arc-shaped workpiece, and improve the accuracy and quality of the corrected workpiece
