Ultrasonic multi-head impact device and method for manufacturing materials such as robots

Abstract

The invention relates to a robot equal material manufacturing and multi-head ultrasonic peening device and method. In order to conform to a manufacturing pattern based on addition in recent years, theequal material ultrasonic peening device and an installation method thereof in additive equal and subtractive material integrated compound manufacturing conducted on a thin-wall part with a complex shape are provided. By combining ultrasonic peening and additive and subtractive material manufacturing, welding residual stress can be eliminated, surface nanocrystallines are obtained, and damaged part repair is achieved, and the internal structure is changed to achieve performance optimization. The device is connected with an industrial robot tail end arm, a robot hand is controlled through programming to run according to a preconceived track, and meanwhile, through an ultrasonic peening gun, the different side surfaces of a part after material addition are peened simultaneously, so that a hammer forging peening equal mateirla shape controlling technology process of the top surface and the bilateral side surfaces of the thin-wall wall part is completed at once. The device and the methodare simple, convenient and lower in cost, for a processed component, residual stress can be eliminated, and surface crystalline grains can be refined.

Description

technical field [0001] The invention relates to a multi-head ultrasonic impact device and method for manufacturing a robot and other materials, which belongs to the thermal hammer forging process of mechanical processing, and is used for controlling the refinement of the surface layer and internal structure of the component after the material is added in the integrated composite manufacturing of adding material and subtracting material . Background technique [0002] In recent years, under the background of resource saving and high-efficiency manufacturing, the additive manufacturing technology based on the "additive" processing mode has shown broad application prospects in the manufacture of thin-walled parts with complex shapes. Additive manufacturing technology is a technology that uses CAD design data to manufacture solid parts by accumulating materials layer by layer. In the field of additive manufacturing, the additive manufacturing technology of metal parts using arc...
