Abstract

The invention discloses a bidirectional correcting device for an incomplete circular-arc-shaped workpiece. The bidirectional correcting device comprises a rotary driving mechanism, a clamping mechanism and a bidirectional hammering mechanism, wherein the rotary driving mechanism is used for enabling the whole bidirectional correcting device to move around the incomplete circular-arc-shaped workpiece, the clamping mechanism is used for clamping a horizontal upper surface and a circular-arc-shaped side surface of the incomplete circular-arc-shaped workpiece, and the bidirectional hammering mechanism is used for realizing knocking correction of the horizontal upper surface and the circular-arc-shaped side surface of the incomplete circular-arc-shaped workpiece; the rotary driving mechanism comprises a driving device, a bearing base, two guide rails and a plurality of bearings; the clamping mechanism is fixed on the bearing base and comprises a movable horizontal surface fixing clamping platform and a movable arc surface fixing clamping platform, wherein the two clamping platforms are the same in structure, and the mounting positions of the two clamping platforms are adjusted according to different surfaces to be machined of the incomplete circular-arc-shaped workpiece; and the bidirectional hammering mechanism is fixed on the bearing base and comprises a support adjusting platform, a C-shaped support and two impact air cylinders.

Description

technical field [0001] The invention relates to a bidirectional straightening device, in particular to a bidirectional straightening device for incomplete arc-shaped workpieces. 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 correcting device for incomplete arc-shaped workpieces, which r...
