Title: FLEXIBLE CLAMP AND METHOD FOR USE IN MILLING BLADES HAVING LARGE COMPLEX CURVED SURFACES
Abstract:
A flexible clamp and a method for use in milling blades having large complex curved surfaces, comprising: a lower portion clamping portion (2) which is arranged on a workbench (1), wherein a flexible clamping portion is cooperatively arranged at an upper side of the lower portion clamping portion (2); two ends of the flexible clamping portion are connected to a horizontal moving mechanism, and an end portion of the horizontal moving mechanism is connected to a vertical moving mechanism; the flexible clamping portion comprises an elastic clamping body which flexibly adheres to a side wall of a blade, the elastic clamping body flexibly clamping an upper portion side wall of the blade, while the lower portion clamping portion (2) clamps a bottom portion of the blade; during processing, the horizontal moving mechanism and the vertical moving mechanism drive the elastic clamping body to adjust the position at which the blade is clamped so as to preserve an area to be processed. The present invention solves the problem of processing vibration during the processing of a thin-walled part having a complex curved surface, and may also reduce processing distortion of thin-walled structures, such as a large-sized blades.
