Abstract

The invention discloses a sucking supporting head provided with rigid and flexible supports and used for machining grids of a thin-walled workpiece. The sucking supporting head comprises a base, wherein ventilation holes used for connection of a negative pressure pump are formed in the right end surface and the side surface of the base; multiple circumferential stepped through holes with parallel axes are uniformly formed in the base in the circumferential direction, a central stepped through hole parallel to the axes of the circumferential stepped through holes is formed in the center of the base, internal threads are arranged on left sides of the multiple circumferential stepped through holes and the left side of the central stepped through hole, a threaded connection part, a left spring and an auxiliary bulb supporting rod sleeved with a right spring are sequentially mounted in each circumferential stepped through hole from left to right, and a rubber suction cup is fixedly connected onto the outer circumference of the right end surface of the base. The sucking supporting head is provided with the flexible supports and the rubber suction cup to reduce vibration of the thin-walled workpiece and is also provided with the rigid supports to accurately position the thin-walled workpiece, meanwhile, the rigidity of the thin-walled workpiece is increased due to the multi-point supports, and the machining precision is improved.

Description

technical field [0001] The invention relates to an adsorption support head, in particular to an adsorption support head for grid processing of thin-walled parts. Background technique [0002] At present, in the aviation manufacturing industry, it is often necessary to process diamond-shaped grids on thin-walled parts. However, due to the relatively low rigidity of thin-walled parts, deformation and chatter are likely to occur under the influence of milling forces during processing, and it is difficult to ensure that thin-walled parts machining accuracy. The commonly used methods for grid processing of thin-walled parts are chemical milling and pattern milling, but the precision of chemical milling is low and the pollution is large, while the efficiency of pattern milling is low and the versatility is poor. [0003] Later, the mirror image processing technology of thin-walled parts was developed. US Patent Document No. US7682112 discloses a method and equipment for machinin...
