Novel ultrasonic shot blasting surface strengthening device

Abstract

The invention discloses a novel ultrasonic shot blasting surface strengthening device. According to the novel ultrasonic shot blasting surface strengthening device, a shot chamber bottom plate is arranged on the upper end side of a fixed base plate, and a shot chamber assembly is arranged on the upper end side of the shot chamber bottom plate; the shot chamber assembly comprises a lower shot chamber and an upper shot chamber, a lower-end shot blasting cavity is formed in the lower shot chamber, and an upper-end shot blasting cavity is formed in the upper shot chamber; the upper shot chamber isprovided with an upper-end test piece station gate opening, and the lower shot chamber is provided with a lower-end test piece station gate opening; a bolt inserting hole is formed in the shot chamber assembly, a test piece locking mechanism comprises a locking pressing plate and a locking bolt screwed in an internal threaded hole of the locking pressing plate, and the lower end part of the locking bolt extends into the bolt inserting hole; and an ultrasonic assembly arranged on the fixed bottom plate comprises an ultrasonic transducer, an amplitude-change pole and a shot blasting tool head,and the upper end of the shot blasting tool head penetrates through a bottom plate through hole of the shot chamber bottom plate from bottom to top and stretches into a shot blasting cavity in the lower end of the lower shot chamber. Through the structural design, the novel ultrasonic shot blasting surface strengthening device has the advantages of being novel in structural design, high in shot blasting efficiency and high in space utilization rate.

Description

technical field [0001] The invention relates to the technical field of ultrasonic shot peening devices, in particular to a novel ultrasonic shot peening surface strengthening device. Background technique [0002] Ultrasonic shot peening is a new type of material surface modification treatment method, which achieves the purpose of increasing the surface strength of the material by producing mechanical deformation on the material surface. [0003] It should be explained that ultrasonic shot peening is to promote the plastic deformation of the surface of the metal parts through the impact of the striker or the shot body on the surface of the metal parts, thereby generating residual compressive stress and nano-layers on the surface of the parts, thereby improving the strength of the metal parts. Purpose. Among them, according to the different shot peening media used, ultrasonic shot peening can be divided into two types: ultrasonic impact (striking pin type) and ultrasonic shot...
