Self-aligning grinding surface nanocrystallization device

Abstract

The invention discloses a self-aligning grinding surface nanocrystallization device. According to the device, surface nanocrystallization of a metal material is induced by means of the principle that grain refinement is caused by plastic deformation. The device is mainly composed of a top variable-speed belt wheel set, a middle driving shaft system, a grinding head assembly, a working table capable of achieving horizontal feeding and longitudinal feeding, and an integrated framework, wherein connection of a main shaft variable-frequency and variable-speed motor and a grinding head system is achieved through the middle driving shaft system, and automatic alignment of a grinding head is achieved through a ball-cage type universal joint. Lead screws on the two sides of the device are in matched transmission with a nut in a middle cross beam where a main shaft motor is located to achieve vertical movement of the middle shaft system, so that the surface of a plate is pressed. Guide rails in the horizontal direction and longitudinal direction are arranged on the working table to achieve bidirectional feeding, and a workpiece clamp is installed on the upper portion of the working table. According to the device, machining efficiency and operation user friendliness are improved greatly, and nanocrystallization effect is good.

Description

technical field [0001] The invention belongs to the field of surface rolling processing of materials, in particular to an adjustable center rolling surface nanometerization device. Background technique [0002] At present, the existing nano-processing devices for the surface of metal materials are mainly divided into two categories: one is a device inspired by traditional shot peening technology, which repeatedly impacts the surface of metal materials through metal balls or cylindrical indenters; One is that the indenter with built-in metal balls rotates, and the balls rotate and roll on the metal surface to cause plastic deformation on the material surface. Among them, due to the limitation of the overall manual loading method and the rigid transmission of the spindle, the existing second type of surface nanometerization device has problems such as small effective processing size, poor operability and high requirements for the flatness of the workpiece by the indenter, and ...
