[0002] In the finish machining process, workpiece is positioned on fixture by vacuum adsorption positioning device, so that the fixture can be reliably attached to the surface of the product, and then the shell is further processed by machining equipment. The existing vacuum adsorption positioning device is generally connected by a jig plate with positioning pins and a vacuum suction tube, and an adsorption force is generated on the shell by directly sucking air through the vacuum suction tube to complete the positioning and fixing of the shell. With this vacuum adsorption positioning device structure, since the vacuum suction tube directly adsorbs and holds the product, residual waste will enter the vacuum suction tube from the vacuum suction port when the jig surface is cleaned after processing, and the accumulation of waste in the pipeline can easily cause pipeline blockage, resulting in unstable suction force for subsequent processing products, which makes the structure and appearance of the processed product not meet the quality requirements. Therefore, we propose a self-positioning vacuum adsorption device for finish machining. SUMMARY
