Abstract

The invention relates to a novel method and equipment for simultaneously rolling and polishing the inner surface and the outer surface of a large thin-wall cylindrical workpiece. The method for rolling and polishing integrates a main shaft mode, a vibration mode and a rotation mode. Due to the loading and unloading mode that a linear motion unit drives a support to lift the workpiece, the mountingmode that a spindle box fixes the workpiece, the outer wall machining mode that the outer surface of the workpiece is covered with a grinding block and grinding fluid, the inner wall machining mode that the workpiece rotates for rolling and polishing, and the mode of generating a motion flow field under driving of a vibration motor, the automatic equipment can simultaneously roll and polish the inner wall and the outer wall of the large thin-wall cylindrical workpiece.

Description

technical field [0001] This patent relates to the field of finishing processing. A method and equipment for simultaneously rolling and finishing the inner and outer surfaces of a large thin-walled tube. Background technique [0002] Surface barrel finishing is to place a workpiece in a free state or a non-free state in a container containing a processing medium, and generate a certain movement form through the workpiece, the container, or both, so that a complex relationship between the workpiece and the abrasive is formed. Relative movement, thereby removing burrs and edge chamfers on the surface of the workpiece, eliminating residual impurities after casting, forging and heat treatment on the surface of the workpiece, refining the microstructure and lattice arrangement of the processed surface, repairing microscopic cracks, and improving the stress state of the workpiece surface Processing methods. [0003] The barrel finish machine mainly includes the following forms: r...
