Description

Self-adaptive fixing device for processing aluminum castings Technical Field The utility model relates to the technical field of aluminum casting machining and fixing, in particular to a self-adaptive fixing device for aluminum casting machining. Background The fixing of the aluminum casting is an important link in the aluminum casting processing process, and ensures the stability and accuracy of the aluminum casting in the processing, testing and assembling processes. The fixing method of the aluminum casting mainly comprises two main types of mechanical fixing and chemical fixing. The mechanical fixing mainly depends on modes of clamping devices, bolt connection and the like to fix the aluminum casting on processing equipment or a workbench. The chemical fixing is to bond the aluminum casting and other components together by using chemical materials such as adhesives. In the process of processing the aluminum castings, the clamping device is widely applied to realizing the clamping and fixing of the aluminum castings to be processed. Irregularities in the shape of the aluminum casting present challenges to the clamping device. Conventional clamping devices are often designed to hold workpieces of relatively regular or standard shape. When facing aluminum castings of varying curvature or shape, these devices may not be effectively adaptable and closely conform to the workpiece surface. Such mismatch may result in insufficient clamping force, movement or deformation of the workpiece during processing, and thus, affect processing accuracy and workpiece quality. The difficulty in adapting the clamping device may also lead to uneven stress on the workpiece. During the clamping process, if the clamping device cannot uniformly distribute the clamping force, the aluminum casting may generate stress concentration due to excessive local pressure. Such stress concentrations may not only lead to deformation of the workpiece, but may also initiate defects such as cracks, and in severe cases even result in rejection of the workpiece.
