Embodiment Construction

[0033] The following examples will further illustrate the present invention, but do not limit the present invention thereby.

[0034] As shown in Figure 1(a)-(b), the novel device for nano-micronizing the surface of metal materials of the present invention consists of four motors (a variable-speed motor 19 on the top to control the middle beam, a spindle motor 11 to control the speed of the rolling head, two It is composed of five main parts: the feed motor 5 for table control feed, the top spindle lift and speed change pulley group 14, the middle spindle drive shaft system, the combination of rolling head, the workbench and the overall frame of the equipment for realizing horizontal and vertical bidirectional feed. The equipment adopts mechanical transmission and pressurization mode: the variable speed motor 19 controlling the middle beam drives the transmission screw 12 on both sides to rotate through the pulley transmission system, so that the middle beam 10 where the rollin...

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 ...
