Method and device for testing shot-peening speed by means of rotary motion

Abstract

The invention discloses a device for testing shot-peening speed by means of rotary motion. The device comprises a nozzle, a shot, a fixed screening plate, a rotary screening plate, a rotating baffle,a rotating shaft and a deformed material layer. The nozzle is arranged downwards. The fixed screening plate is disposed below the nozzle. The rotary screening plate is disposed under the fixed screening plate. The rotating baffle is disposed under the rotary screening plate. The rotary screening plate and the rotating baffle are disposed at two ends of the rotating shaft respectively. The fixed screening plate and the rotary screening plate are provided with single through holes. The rotating baffle is provided with the deformed material layer. The centroid of the nozzle coincides with the axis of the through hole of the fixed screening plate. When the rotary screening plate is rotated to a certain angle, the axis of the through hole of the fixed screening plate and the axis of the throughhole of the rotary screening plate coincide with each other. The invention provides a method and device for testing the shot-peening speed by means of rotary motion, which can accurately and conveniently measure the speed of the shot.

Description

technical field [0001] The invention relates to a method and a device for testing shot peening speed by rotating motion, and belongs to the technical field of speed measurement. Background technique [0002] Shot peening is to spray high-speed shot blasting onto the surface of the part to make the surface of the part deform and form a strengthening layer with a certain thickness to improve the fatigue strength of the part. It can also be used for surface matting, removal of scale and elimination of residual stress. Shot peening is a surface strengthening process widely used in factories. The speed of shot peening will directly affect the effect of surface strengthening treatment, therefore, the speed of shot peening is an important technical indicator. At present, there are relatively few methods and devices that can measure the speed of small volumes and high speeds more accurately, and the equipment is expensive (such as high-speed photography equipment, particle image ve...

Problems solved by technology

At present, there are relatively few methods and devices that can accurately measure the speed of small volumes and high speeds, and the equipment is expensive (such as high-speed photography equipment, particle image velocimeters, photoelectric tube velocimeters, etc.)

These methods and devices obviously cannot meet the research needs of those skilled in the art. Therefore, it is necessary to design a shot peening velocity measuring device and method thereof with simple structure, accurate velocity measurement, low cost and effective
