Ultrasonic shot blasting device for shaft parts

Abstract

The invention discloses an ultrasonic shot blasting device for shaft parts. The ultrasonic shot blasting device for the shaft parts comprises a workbench, an ultrasonic vibration device and a clampingdevice, and is characterized in that the ultrasonic vibration device consists of a transducer A, an amplitude-change pole A, a transducer B, an amplitude-change pole B and a circular tool head; the ultrasonic vibration device is mounted on the workbench through a support A and a support B; a through hole is formed in the workbench, a shot blasting chamber composed of a bottom plate, the annular tool head, an annular electromagnet and a top plate is arranged above the through hole, shots are placed in the shot blasting chamber, the shaft parts to be subjected to shot blasting are vertically placed through the clamping device and extend into the shot blasting chamber, and the clamping device is composed of a mechanical arm A, a mechanical arm B, a guide rail, a sensor A and a sensor B, thesensor A and the sensor B are mounted on the guide rail. According to the ultrasonic shot blasting device for the shaft parts, the annular tool head generates ultrasonic traveling waves under the combined action of two ultrasonic vibration heads, the shots are driven to conduct shot blasting treatment on the circumferential face of the shaft parts at the same time, and shot blasting uniformity isguaranteed.

Description

technical field [0001] The invention relates to the technical field of parts surface strengthening equipment, in particular to an ultrasonic shot peening device for shaft parts. Background technique [0002] Shot peening is a cold working surface modification and forming technology. Under the action of high-pressure wind or compressed air, the projectile hits the workpiece at a certain speed, causing elastic-plastic deformation of the material and forming pits on the metal surface, resulting in countless depressions. Overlap to form a uniform residual compressive stress layer. However, the impact force of traditional mechanical shot peening projectiles is limited, and the depth of residual stress produced by it is also limited, and the dents on the surface are relatively deep, resulting in increased metal surface roughness, and subsequent finishing processes need to be added to ensure the integrity of the parts roughness. In addition, dry shot peening is currently the most...
