Abstract

The invention relates to an auxiliary supporting vibration suppression device for milling a thin-wall curved-surface part. The auxiliary supporting vibration suppression device comprises a base, base bolts, a supporting plate, an adjusting screw rod, an adjusting block, a supporting bolt and a rubber head. The base is fixed to the two sides of the thin-wall curved-surface part through the base bolts, the bottom of the adjusting screw rod is placed in a reserved groove of the base, the adjusting block penetrates through the supporting plate and the adjusting screw rod, vertical movement of the adjusting block is controlled by screwing the adjusting screw rod, the supporting bolt penetrates into a horizontal threaded hole of the adjusting block, the rubber head sleeves the head of the supporting bolt, and the supporting bolt is screwed to be adjusted to abut against the surface of the thin-wall curved-surface part and is tightened and fixed. According to the device, the rigidity of the thin-wall curved-surface part is improved, and the thin-wall curved-surface part is not prone to deformation during milling, so that the milling vibration suppression effect is achieved.

Description

technical field [0001] The invention relates to the field of milling, in particular to an auxiliary support and damping device for thin-walled curved surface parts. Background technique [0002] When thin-walled curved surface parts are milled, due to the thin-walled characteristics of the parts, they are easily deformed during the processing, and then chatter occurs, making the processing unstable and affecting the processing quality and efficiency of the parts. [0003] Document 1 "Y.Q.Yang, W.Dai, Q.Liu, Design and implementation of two-degree-of-freedom tuned mass damper in milling vibration mitigation. Journal of Sound and Vibration, 2015, 335, 78-88." A vibration suppression method based on an adjustable mass damper, the method adjusts the dynamic parameters of the adjustable mass damper to match the modal parameters of the workpiece, so as to achieve the effect of vibration suppression. However, this method can only be used on thin-walled straight plates, and is not ...
