Abstract

The invention relates to a laser shot peening device suitable for a plate-shaped sample. The laser shot peening device suitable for the plate-shaped sample comprises a power device, a transmission device, a lens assembly device and a tank device sequentially arranged along the horizontal direction, wherein the power device comprises a motor; the motor is in transmission connection with a gear; thegear is connected with a support table through a longitudinal rack; the motor is used for driving the gear to rotate, so that the support table moves along the longitudinal rack in a reciprocating way; the transmission device comprises a support table; the lens assembly device is arranged on the support table and comprises a laser emission instrument; a laser beam emitted by the laser emission instrument enters the tank device through the lens assembly; the tank device comprises a protection tank; a reflecting mirror is arranged in the protection tank; and the sample is located on a path of alaser beam reflected by the reflecting mirror. The laser shot peening device suitable for the plate-shaped sample provided by the invention is easy to implement in a lab, simple to operate and less influenced by the environment.

Description

technical field [0001] The invention relates to the field of material surface modification experiment devices, in particular to a laser shot peening strengthening device suitable for plate samples. Background technique [0002] With the continuous development of military devices, aerospace, automobiles and other fields, the performance of metal materials has become a research hotspot. Under some special conditions, alloy materials are required to serve in high temperature environments, and they are required to have good high temperature strength and fatigue resistance. and creep properties. However, at present, most of the metal components often have fatigue cracks on the surface under the complex service environment for a long time, which will cause the parts to fail. In order to improve the service life of structural parts in the service environment and increase the reliability of materials, surface modification technology has been more and more researched.
