Abstract

The invention provides a method and device for carrying out polishing through flowing of viscoelasticity abrasive materials with spiral complex curved surfaces and belongs to the field of mechanical equipment. The device comprises a machined screw rod, the abrasive materials, a sealing box, a fixing die, a gap and a screw rod drive device. One end of the machined screw rod is connected with the screw rod drive device, the other end of the machined screw rod is immersed into the abrasive materials, the screw rod drive device is installed on the upper portion of the sealing box, the fixing die is installed in the sealing box through a supporting rod, the abrasive materials are the viscoelasticity abrasive materials, and the fixing die is a tubular hollow die. When the screw rod drive device drives the machined screw rod to rotate at a high speed, the abrasive materials move upwards along the spiral surfaces; meanwhile, under restraining of the fixing die, the abrasive materials extrude the surface of the screw rod, polish the surface of the screw rod, and flow back to the sealing box after reaching the top end of the fixing die, so that polishing of a circulating type is achieved; according to the method and the device, the screw rod can be polished efficiently with high quality and uniformity.

Description

technical field [0001] The invention relates to a viscoelastic abrasive flow polishing method and device for spiral complex curved surfaces, belonging to the field of mechanical equipment. Background technique [0002] Spiral curved surface is a kind of complex curved surface. The processing equipment of complex curved surface parts has complex structure and high cost. Its surface polishing technology has become a hot spot in the field of precision machining. Among them, the screw is a typical workpiece with a helical surface. In recent years, the screw has been widely used in air compressors, refrigerators, industrial pumps, and plastic machinery. Screw is the "heart" part of plastic machinery, and its quality directly affects the life of the machine and the quality of molded products. How to process high-quality screw to make it meet the design requirements has become an important topic in the plastic machinery manufacturing industry at home and abroad. [0003] At pres...
