The invention relates to a specimen rotating device of high-temperature short-blasting in the mechanical processing technical field, which comprises a rotation shaft, a shafts specimen holder, a connecting system, a body, a rotating system and a specimen heating system, wherein one end of the rotation shaft is used to fix the shafts specimen holder, the other end is horizontally fixed on the bodythrough the connecting system and is connected with the connecting system, the rotation shaft is placed in the metal tube of the connecting system, and is connected with the specimen heating system bymeans of bearings, the shafts specimen holder is placed in the specimen heating system, and plastic sleeves are all sleeved on the outer side of the connecting system and the shafts specimen holder.The device is used to hold and rotate shafts specimen, in particular to nonferrous metal such as magnesium alloy specimen, increases the plastic deformability thereof through firstly heating up specimen with high temperature, wherein the highest temperature can reach 300DEG C, then conducting short-blasting treatment for the specimen in order to increase the evenness and stability of the specimensurface state after treated, further to increase the fatigue property thereof at largest maximum, and can prevent foreign matter such scrap iron and the like from contaminating the specimen simultaneously.
Description
technical field [0001] The invention relates to a device in the technical field of machining, more specifically, a sample rotation device for high temperature shot peening. Background technique [0002] As we all know, shot peening can increase the fatigue life and fatigue strength of the sample, clean the surface hygiene of mechanical parts, improve the quality of the workpiece surface paint and galvanizing process, etc.; for metals with poor plasticity such as magnesium alloys, shot peening The strengthening effect is limited. In order to improve the shot peening effect of metals with poor plasticity such as magnesium alloys to a greater extent, people have developed high temperature shot peening. Compared with room temperature shot peening, high temperature shot peening can lead to greater Plastic deformation causes greater residual compressive stress and can enhance the stability of residual stress, so high temperature shot peening is more effective for improving fatigue...
